Description

Technical Field

The invention relates to a cleaning technology, in particular to a cleaning device and a color sorter.

Background

In the color selector, the cleaning device is mainly structurally characterized in that a cylinder drives a cleaning member to move, and glass of the sorting chamber device is cleaned by a dust cleaning brush arranged on the cleaning member.

At present, the attaching tightness of the ash cleaning brush and glass of the sorting chamber device is mainly adjusted through a torsion spring. In the cleaning process, the elastic force provided by the torsion spring is carried out through the force arm extending out at two ends of the spring body and rotating around the central shaft of the spring body, and the torsion spring can only finely adjust the bonding tightness of the ash cleaning brush and the glass of the sorting chamber device due to the limitation of the installation of the working torsion angle stress arm of the force arm. When the glass manufacturing deviation of the sorting chamber is large or the surface flatness of the glass generates large fluctuation on the surface of the glass due to the light emission and the generated heat of the photoelectric system of the sorting chamber device in the using process, the torsion spring can not be increased to enable the ash cleaning brush to be better attached to the glass, so that the ash cleaning effect is affected.

The beneficial effects of the invention are as follows: when the ash cleaning brush receives the contact pressure increase between the ash cleaning brush and the glass caused by the fluctuation change of the surface flatness of the glass, the increase of the contact pressure is transmitted to the spiral spring through the ash cleaning brush and the movable support, and the spiral spring is axially compressed and the movable support pivots relative to the fixed support, so that the increased contact pressure is released and reduced; when the ash brush receives the reduction of the contact pressure between the ash brush and the glass caused by the fluctuation change of the surface flatness of the glass, the reduction of the contact pressure is transmitted to the spiral spring through the ash brush and the movable support, and the spiral spring axially stretches (along the first rod and the second rod of the guide rod pair) due to the elastic action and the movable support pivots relative to the fixed support, so that the reduced contact pressure obtains the external force of the spiral spring to increase the contact pressure between the ash brush and the glass. Therefore, even if the change of the contact pressure between the ash cleaning brush and the glass, which is generated by the fluctuation and change of the surface flatness of the glass, is large, the movable support, the fixed support, the spiral spring and the guide rod pair can adjust the large pressure change to a stable state together, so that the ash cleaning brush always keeps good fit with the glass during working, and the ash cleaning effect is improved.

Furthermore, expressions of directions indicated for explaining the operation and constitution of each member in the embodiment such as up, down, left, right, front and rear and the like are not absolute but relative, and although these directions are appropriate when each member is in the position shown in the drawings, when these positions are changed, these directions should be interpreted differently to correspond to the changes.

Fig. 1 shows a schematic diagram of a color sorter according to an embodiment of the invention.

As shown in fig. 1, the color sorter comprises a feeding device M1, a sorting chamber device M2, a rejecting device M3, a receiving device M4, an ash blocking plate M5, a cleaning device M6 and a dust collecting device M7.

The feeding device M1 includes a feed hopper M11, a vibrating hopper M12, a vibrator M13, and a feeding channel M14.

The feed hopper M11 is adapted to receive the material particles to be selected. The vibrating hopper M12 communicates with the feed hopper M11 to receive material particles from the feed hopper M11. The vibrator M13 is connected to the vibration hopper M12 and is configured to generate reciprocating vibrations toward and away from the feed channel M14, so that the material particles in the vibration hopper M12 vibrate and enter the feed channel M14 in a material-by-material manner. The feed channel M14 is arranged to be inclined with respect to the Z direction (i.e. up-down direction) so as to enable one material to fall down by gravity.

The sorting chamber device M2 judges whether the material particles meet the requirements according to the colors of the material particles input by the feeding channel M14. The sorting chamber arrangement M2 may be implemented using any suitable optoelectronic system. In order to avoid the influence of dust or the like on the optoelectronic system, the sorting chamber means M2 is provided with a light-penetrable glass G.

The rejecting device M3 is communicatively connected to the sorting chamber device M2, and based on the sorting chamber device M2, whether the material particles meet the requirements or not is judged, and the corresponding material particles are subjected to air injection to change the material track so as to reject. The air injection may be implemented based on any suitable air path system and control system, and as shown in fig. 1, the rejecting device M3 includes an injection valve M31 and an injection nozzle M32, where the injection valve M31 communicates with the air path system and is in communication with the sorting chamber device M2, the injection nozzle M32 communicates with the injection valve M31 and is provided with an injection nozzle plate M321 on a side facing the feeding channel M14, and the injection nozzle plate M321 is provided with an injection hole (not shown). For example, when the sorting chamber device M2 determines that the material particles do not meet the requirements according to the color of the material particles input by the feeding channel M14, the sorting chamber device M2 communicates to the spraying valve M31, and the spraying valve M31 is started, so that the air jet provided by the air path system is sprayed to the determined material particles entering the sorting chamber device M2 through the spraying hole of the nozzle plate M321, thereby changing the motion trail of the determined material particles; when the sorting chamber device M2 judges that the material particles meet the requirements according to the colors of the material particles input by the feeding channel M14, the sorting chamber device M2 is communicated to the spray valve M31, and the spray valve M31 is not started, so that the movement track of the material particles is not changed. Of course, the foregoing operation procedure may also be set as follows: when the sorting chamber device M2 judges that the material particles meet the requirements according to the colors of the material particles input by the feeding channel M14, the operation of the spray valve M31 is started, so that the motion trail of the judged material particles is changed; when the sorting chamber device M2 judges that the material particles do not meet the requirements according to the colors of the material particles input by the feeding channel M14, the sorting chamber device M2 is communicated to the spraying valve M31, and the spraying valve M31 is not started, so that the movement track of the material particles is not changed.

The receiving device M4 is provided with a first cavity M41 and a second cavity M42 spaced apart. It should be noted that, the first cavity M41 may receive material particles that meet the requirements, or may receive material particles that do not meet the requirements; the second cavity M42 may receive material particles meeting the requirements, or may receive material particles not meeting the requirements, so long as the material particles are separated and stored after being sorted.

The ash blocking plate M5 is arranged above the material receiving device M4 to block external dust from falling into the first cavity M41 and the second cavity M42 of the material receiving device M4. In the figure, the ash blocking plate M5 is shown as being disposed above the first chamber M41, but the ash blocking plate M5 may be disposed as well above the second chamber M42 as actually required.

The cleaning device M6 cleans the glass G, the soot sheet M5, and the nozzle plate M321 of the color sorter M2.

The dust suction device M7 faces the dust blocking plate M5 to suck dust falling on the dust blocking plate M5. For example, the dust suction device M6 may directly suck the dust falling on the dust blocking plate M5, or the dust suction device M6 may suck the dust cleaned by the cleaning device M7 from the dust blocking plate M5.

The construction of the cleaning device M6 is described in detail below.

Fig. 2 shows a perspective view of an embodiment of the cleaning device M6 of the color sorter, in which the brush holder 18 on the right is directly connected to the connecting mechanism 11 for convenience of explanation. Fig. 3 is a perspective view of the cleaning device M6 of fig. 2, seen from another angle, wherein the drive mechanism 10 is omitted for clarity, and wherein the brush holder 18 on the left is directly connected to the connecting mechanism 11.

As shown in fig. 2 and 3, the cleaning device M6 includes a driving mechanism 10, a connecting mechanism 11, a fixed bracket 12, a movable bracket 13, a guide bar pair 14, a coil spring 15, and an ash brush 16. The cleaning device M6 may further include a shaft 17, a brush holder 18, a release limiting mechanism 19, and a rotation limiting mechanism 20, depending on the actual use. Depending on the actual use, the cleaning device M6 may further comprise a dust guard brush 21 and a nozzle plate brush 22.

Fig. 4 shows a partially enlarged perspective view of the drive mechanism 10 of the cleaning device M6; FIG. 5 shows a cross-sectional view of a simplified portion of FIG. 4; FIG. 6 shows a cross-sectional view of the bushing structure 104 of the drive mechanism 10; fig. 7 is a plan view of the bushing structure 104.

The drive mechanism 10 is for effecting at least driving in the X direction. Preferably parallel to the surface of the glass G in the X direction, in other words, the X direction is preferably the direction of reciprocal linear movement of the soot cleaning brush 16. Depending on the actual use, the drive mechanism 10 may be used to achieve only driving in the X direction. As shown in fig. 3, the driving mechanism 10 includes a linear cylinder 101, a slider 102, and two mounting brackets 103. The driving mechanism 10 may further comprise two bushing structures 104 and two nuts 105, depending on the actual use.

The linear cylinder 101 includes an axis extending in the X direction. As shown in fig. 5, each end portion of the linear cylinder 101 has a threaded portion 101a provided with a thread, and a portion of the linear cylinder 101 adjacent to the threaded portion 101a forms a flange surface 101b, in other words, a portion of the linear cylinder 101 adjacent to the threaded portion 101a has a diameter larger than that of the threaded portion 101 a.

The sliding block 102 is sleeved on the linear cylinder 101 and is driven by the linear cylinder 101. Specifically, the slider 102 has a circular hole 102a penetrating therethrough, the slider 102 is fitted over the linear cylinder 101 via the circular hole 102a, and the slider 102 is rotatable about the axis of the linear cylinder 101 and is reciprocally movable along the axis of the linear cylinder 101 by the drive of the linear cylinder 101. The slider 102 may be rectangular or square in shape.

Two mounting brackets 103 are respectively connected to both ends of the linear cylinder 101 to suspend the linear cylinder 101. Each mounting bracket 103 is adapted to be secured to a frame (not shown). As shown in fig. 4 and 5, each mounting bracket 103 is provided with a through hole h. Specifically, as shown in fig. 2 and 4, each mounting bracket 103 includes a first flat plate portion 103a. Further, each mounting bracket 103 may further include a second flat plate portion 103b, a third flat plate portion 103c, and a fourth flat plate portion 103d. The through hole h is provided in the first flat plate portion 103a, and the first flat plate portion 103a intersects (preferably is perpendicular to) the linear cylinder 101 and is fit over the corresponding bush structure 104 through the through hole h in a clearance fit manner. The second flat plate portion 103b is bent from the first flat plate portion 103a and extends away from the linear cylinder 101 in the X direction. The third flat plate portion 103c is bent from the second flat plate portion 103b and extends toward the linear cylinder 101 in the Y direction. The fourth flat plate portion 103d is bent from the third flat plate portion 103c and extends away from the linear cylinder 101 in the Z direction, and the fourth flat plate portion 103d is for fixing to the frame.

Each of the bush structures 104 is fitted to the through hole h of the corresponding mounting bracket 103 with a clearance fit (that is, each of the mounting brackets 103 is fitted over the bush structure 104 with a clearance fit) and protrudes outside the through hole h of the corresponding mounting bracket 103 in the X direction (that is, the dimension of each of the bush structures 104 in the X direction is larger than the dimension of the through hole h in the X direction). Each bush structure 104 is fitted over the threaded portion 101a of each end of the linear cylinder 101 with a clearance fit, in other words, the threaded portion 101a of each end of the linear cylinder 101 passes through the corresponding bush structure 104 with a clearance fit.

Each bushing structure 104 may take a variety of forms. In the example of fig. 4-7, each bushing structure 104 may be an integrally formed annular body. In another embodiment of each bushing structure, not shown, the bushing structure 104 may be comprised of a plurality of cylinders arranged in a ring.

In the example of fig. 4-7, each bushing structure 104 includes a barrel portion 104a and a flange portion 104b. The flange portion 104b extends radially outward from the entire periphery of the barrel portion 104 a. The cylindrical portion 104a of each bush structure 104 is fitted to the through hole h of the corresponding mounting bracket 103 with a clearance fit, and the flange portion 104b of each bush structure 104 is located outside the through hole h of the corresponding mounting bracket 103 and spaced apart from the corresponding mounting bracket 103 in the X direction.

An outer peripheral surface of each bush structure 104 (specifically, for example, an outer peripheral surface of the cylindrical portion 104 a) corresponding to the through hole h is formed with an anti-rotation structure R together with an inner peripheral surface corresponding to the through hole h. The rotation preventing structure R prevents each bush structure 104 (specifically, for example, the cylindrical portion 104 a) from rotating in the through hole h of the corresponding mounting bracket 103, and further prevents the rectilinear cylinder 101 from rotating together with the nut 105. The anti-rotation structure R may take any suitable form. In the example of fig. 4 and 5, the outer peripheral surface of the cylindrical portion 104a of each bushing structure 104 is provided with a first plane P1 and a first arc surface C1, and the inner peripheral surface of the through hole h of the corresponding mounting bracket 103 is provided with a second plane P2 and a second arc surface C2, where the first plane P1 and the second plane P2 are opposite and the first arc surface C1 and the second arc surface C2 are opposite to form an anti-rotation structure R. The relationship of the first plane P1, the first circular arc surface C1, the second plane P2, and the second circular arc surface C2 in terms of dimensions is sufficient to prevent each of the bush structures 104 (specifically, for example, the cylindrical portion 104 a) from rotating in the through hole h of the corresponding mounting bracket 103. In other embodiments, the outer peripheral surface of the cylindrical portion 104a and the inner peripheral surface of the through hole h of the corresponding mounting bracket 103 may form a concave-convex fit structure, and the anti-rotation structure R can be realized as well.

Each nut 105 is threadedly engaged with the threaded portion 101a of each end of the linear cylinder 101 to clamp the corresponding bushing structure 104 between the corresponding flange face 101b of the linear cylinder 101 and the nut 105. Specifically, as shown in fig. 5, each nut 105 is pressed against the outer surface of the cylindrical portion 104a of the corresponding bush structure 104 in the X direction. Based on the above-mentioned each bush structure 104 being mounted in the through hole h of the corresponding mounting bracket 103 in a clearance fit and protruding outside the through hole h of the corresponding mounting bracket 103 in the X direction, each bush structure 104 is sleeved on the threaded portion 101a of each end portion of the linear cylinder 101 in a clearance fit, at this time, each mounting bracket 103 will only play a role of suspending the linear cylinder 101 without receiving the torsion of the nut 105, so that each mounting bracket 103 will not deform, and further the interval between the two mounting brackets 103 remains stable, and the stability and flatness of the suspension support of the linear cylinder 101 remain stable, thereby ensuring the stability of the linear cylinder 101 driven in the X direction. In addition, when each nut 105 is screwed with the threaded portion 101a at each end of the linear cylinder 101, since each bushing structure 104 is sleeved on the threaded portion 101a at each end of the linear cylinder 101 in a clearance fit manner, the torsion and compression force during the screwing process of each nut 105 and the threaded portion 101a can be randomly dispersed in a part (the flange portion 104b can also play a role in dispersing torsion and compression force) due to the clearance fit between each bushing structure 104 and the threaded portion 101a, so that when the nut 105 completes clamping the corresponding bushing structure 104 between the corresponding flange surface 101b of the linear cylinder 101 and the nut 105, the torsion and compression force transferred to the linear cylinder 101 can be reduced, thereby reducing the deflection deformation of the linear cylinder 101, further reducing the internal stress generated by the deflection deformation of the cylinder 101 and being transferred to the ash brush 16 via the connecting mechanism 11 (and the fixing bracket 12 and the brush frame 18 adopted in some cases), finally reducing the influence on the balance and stability of the contact force between the ash brush 16 and the glass G, facilitating the operation stability of the ash brush 16, in addition, reducing the wear between the slide block 102 and the linear cylinder 101, and improving the durability of the linear cylinder 101.

As shown in fig. 2 and 3, the connection mechanism 11 is fixedly connected to the driving mechanism 10 to move with the driving mechanism 10 under the driving of the driving mechanism 10. Specifically, for example, the connection mechanism 11 is fixedly connected to the slider 102.

In the example of fig. 2 and 3, the connection mechanism 11 includes a mount 111. The connection mechanism 11 may also include a connection plate 112.

In the example of fig. 2 and 3, the mount 111 is fixedly connected to the drive mechanism 10 to move with the drive mechanism 10 under the drive of the drive mechanism 10. Specifically, as shown in fig. 2, the mount 111 is fixedly connected to the slider 102.

In the example shown in fig. 2, one end of the connection plate 112 is fixed to the slider 102, and the other end of the connection plate 112 is fixed to the mount 111. More specifically, as previously described, the slider 102 may be rectangular or square in shape, and accordingly, the connecting plate 112 is attached and fixed face-to-face to one surface of the slider 102. Preferably, the plate surface of the connection plate 112 is parallel to the X-direction, and the connection mechanism 11 is mirror-symmetrical in structure with respect to the center surface 113, and the center surface 113 is perpendicular to the X-direction, thereby facilitating symmetrical arrangement of various components attached to the connection mechanism 11, which will be described later.

Fig. 8 shows an assembled perspective view of the fixed bracket 12, the movable bracket 13, the guide bar pair 14, and the coil spring 15 of the cleaning device M6, viewed from one angle; fig. 9 shows an assembled perspective view of the fixed bracket 12, the movable bracket 13, the guide bar pair 14, and the coil spring 15 of the cleaning device M6, viewed from another angle.

As shown in fig. 8 and 9, the fixing bracket 12 includes a connection portion 121 and an extension portion 122. Depending on the actual use, the fixing bracket 12 may further include a mounting portion 123. Depending on the actual use, the fixing bracket 12 may further include a limiting portion 124.

As shown in fig. 8 and 9, the connection portion 121 is fixedly connected to the connection mechanism 11 (specifically, for example, the mounting seat 111, but not limited thereto, and an appropriate portion or member of the connection mechanism 11 may be selected according to actual needs). Specifically, the connection portion 121 of the fixing bracket 12 includes a first plate portion 121a, a second plate portion 121b, and a third plate portion 121c, the first plate portion 121a and the second plate portion 121b being disposed opposite to each other, the third plate portion 121c being connected between the first plate portion 121a and the second plate portion 121b and to the extension portion 122.

As shown in fig. 8 and 9 in combination with fig. 3, the extension portion 122 extends from the connection portion 121 in the Z direction. The direction in which the extension portion 122 extends in the Z direction may be determined depending on the actual situation, in other words, the extension portion 122 may protrude from the connection portion 121 in the Z direction forward upward, obliquely upward, forward downward, or obliquely downward, depending on the actual situation of use, but in the example shown in the drawing, the extension portion 122 extends obliquely downward in the Z direction from the connection portion 121. As shown in fig. 9, the extension 122 is preferably flat plate-shaped.

As shown in fig. 8 and 9, the mounting portion 123 is fixedly connected to the connection portion 121 and fixedly mounted on the connection mechanism 11 (specifically, for example, the mounting seat 111, but not limited thereto, and an appropriate portion or member of the connection mechanism 11 may be selected according to actual needs). In other words, the connection portion 121 is fixedly mounted on the connection mechanism 11 via the mounting portion 123. Of course, the mounting portion 123 may not be used, and the connecting portion 121 may be directly and fixedly connected to the connecting mechanism 11. The mounting portion 123 may be provided with a waist hole, and is connected with the connection mechanism 11 in a waist hole manner, so that the distance and the tightness between the ash cleaning brush 16 and the glass G can be conveniently and large-sized adjusted.

As shown in fig. 8 and 9, the limiting portion 124 extends outward from the connecting portion 121 toward the first portion 131 of the movable bracket 13 and interferes with the pivot track of the first portion 131 of the movable bracket 13 to limit the angle at which the movable bracket 13 pivots relative to the fixed bracket 12. In addition, the stopper 124 also serves to prevent the coil spring 15 from coming out of the first and second levers 141 and 142. Specifically, the stopper 124 includes a first tab portion 124a and a second tab portion 124b, the first tab portion 124a extending outwardly from the first plate portion 121a toward the third wall portion 131c and interfering with the pivotal trajectory of the third wall portion 131c of the first portion 131 of the movable bracket 13, and the second tab portion 124b extending outwardly from the second plate portion 121b toward the third wall portion 131c and interfering with the pivotal trajectory of the third wall portion 131c of the first portion 131 of the movable bracket 13.

As shown in fig. 8 and 9, the movable bracket 13 includes a first portion 131 and a second portion 132. The first portion 131 is pivotally connected to the connecting portion 121 of the fixed bracket 12. The second portion 132 extends from the first portion 131 and is opposite the extension 122 of the fixed bracket 12 (i.e., a direction in which the second portion 132 and the extension 122 are opposite each other intersects the Z-direction and the X-direction). The second portion 132 is preferably flat plate-shaped so that the interval between the second portion 132 and the extension portion 122 can be well defined when the extension portion 122 is also flat plate-shaped; more preferably, the second portion 132 and the extension portion 122 are parallel to each other, so that the compression limit of the coil spring 15 and the sizes of the first rod 141 and the second rod 142, which will be described later, can be precisely determined. To achieve a pivotal connection, in the example of fig. 8 and 9, the first portion 131 of the movable bracket 13 and the connecting portion 121 of the fixed bracket 12 comprise portions that nest with each other. Specifically, the first portion 131 of the movable bracket 13 includes a first wall portion 131a, a second wall portion 131b, and a third wall portion 131c, the first wall portion 131a and the second wall portion 131b are opposite to each other, the third wall portion 131c is connected between the first wall portion 131a and the second wall portion 131b and is connected to the second portion 132, the first wall portion 131a is juxtaposed and spaced apart from the outer side of the first wall portion 131a, and the second wall portion 131b is juxtaposed and spaced apart from the outer side of the second wall portion 131b to form the portions nested with each other (the "space" is used to ensure smoothness of pivoting of the movable bracket 13), and the third wall portion 131c is opposite to the third plate portion 121 c.

In the example of fig. 8 and 9, the pair of guide bars 14 comprises a first bar 141 and a second bar 142, the first bar 141 being fixed (preferably with the axis perpendicular to the X-direction, even more preferably with the axis perpendicular extension 122) to the extension 122 of the fixed support 12 and the second bar 142 being fixed (preferably with the axis perpendicular to the X-direction, even more preferably with the axis perpendicular extension 122) to the second portion 132 of the mobile support 13. The first rod 141 and the second rod 142 are axially opposite. The first lever 141 includes a first axial end surface 141a and a first support portion 141b, and the second lever 142 includes a second axial end surface 142a and a second support portion 142b, the first axial end surface 141a and the second axial end surface 142a facing each other, the first support portion 141b and the second support portion 142b being located between the extension portion 122 of the fixed bracket 12 and the second portion 132 of the movable bracket 13. Preferably, when the movable bracket 13 is opposite to the fixed bracket 12 so that the first axial end surface 141a and the second axial end surface 142a are close to each other, the first axial end surface 141a and the second axial end surface 142a are kept out of contact (i.e. are spaced apart) all the time, so that the adjustment range of the tightness of the spiral spring 15 for attaching the ash brush 16 to the glass G is facilitated to be improved. Of course, the abutment of the first axial end face 141a and the second axial end face 142a may also be used to define the limit compression degree of the coil spring 15.

In the example of fig. 8 and 9, the coil spring 15 is sleeved on the first lever 141 and the second lever 142 (specifically, the coil spring 15 is sleeved on the first supporting portion 141b of the first lever 141 and the second supporting portion 142b of the second lever 142). Both ends of the coil spring 15 are abutted against the extension portion 122 of the fixed bracket 12 and the second portion 132 of the movable bracket 13, respectively. In the example of fig. 8 and 9, the coil springs 15 and the pairs of guide bars 14 are arranged together in groups, the groups being arranged in a row between the extension 122 of the fixed bracket 12 and the second portion 132 of the movable bracket 13. Preferably, the arrangement direction is parallel to the X direction, in other words, the axial direction of the first rod 141 and the second rod 142 is orthogonal to the X direction. Of course, the coil spring 15 and the pair of guide bars 14 may also be arranged together in a single group, the position being centrally located between the extension 122 of the fixed bracket 12 and the second portion 132 of the movable bracket 13. The number of sets of coil springs 15 and pairs of guide rods 14, the stiffness, number of turns, pitch diameter of coil springs 15, and the length and diameter of the corresponding guide rods 14 can be determined based on the degree of tightness of fit required for the actual desired application of the brush 16 to glass G.

As shown in fig. 2, the ash brush 16 is attached to the movable bracket 13. The connection part of the ash removing brush 16 and the movable support 13 is not limited, so long as the work of the ash removing brush 16 and the movable support 13 is not affected. Preferably, the ash brush 16 is attached to one of the first portion 131 and the second portion 132 of the movable bracket 13, and more preferably, the ash brush 16 is attached to the second portion 132 of the movable bracket 13 to avoid interference with the pivoting of the escape restriction mechanism 19 described later, while reducing the complexity of the design. In operation, when the soot cleaning brush 16 receives an increase in contact pressure with the glass G due to a fluctuation in the surface flatness of the glass G, the increase in contact pressure is transmitted to the coil spring 15 through the soot cleaning brush 16, the movable bracket 13, and the coil spring 15 is axially compressed and the movable bracket 13 pivots (rotates clockwise in fig. 3) with respect to the fixed bracket 12, so that the increased contact pressure is released to be reduced; when the soot cleaning brush 16 receives a decrease in contact pressure with the glass G due to fluctuation variation in surface flatness of the glass G, the decrease in contact pressure is transmitted to the coil spring 15 through the soot cleaning brush 16, the movable bracket 13, and when the coil spring 15 is axially elongated (along the first rod 141 and the second rod 142 of the guide rod pair 14) by elastic action and the movable bracket 13 is pivoted (counterclockwise in fig. 3) with respect to the fixed bracket 12, the decreased contact pressure is caused to increase the contact pressure between the soot cleaning brush 16 and the glass G by the external force of the coil spring. Therefore, even if the change of the contact pressure between the ash cleaning brush 16 and the glass G, which is generated by the fluctuation and change of the surface flatness of the glass G, is large, the movable support 13, the fixed support 12, the spiral spring 15 and the guide rod pair 14 can be adjusted to a stable state together, so that the ash cleaning brush 16 always keeps good adhesion with the glass G during working, and the ash cleaning effect is improved.

The ash brush 16 includes a brush skin 161 and a brush cover 162. The brush cover 161 is mounted on the brush cover 162, and the brush cover 162 is connected to the movable bracket 13. The brush 16 may also include two shafts 163, depending on the application. As shown in fig. 8 and 9, the shaft body 17 passes through the aforementioned portions nested with each other to pivot the first portion 131 of the movable bracket 13 with respect to the connection portion 121 of the fixed bracket 12 about the axis of the shaft body 17.

Specifically, the shaft 17 includes a first sub-shaft 171 and a second sub-shaft 172. The first sub-shaft 171 has a first sub-shaft end face 171a, and the second sub-shaft 172 has a second sub-shaft end face 172a, the first sub-shaft end face 171a and the second sub-shaft end face 172a facing each other and being spaced apart. The first sub-shaft 171 penetrates the first wall portion 131a and the first plate portion 121a, wherein the first sub-shaft 171 penetrates the first wall portion 131a fixedly with the first wall portion 131a, and the first sub-shaft 171 penetrates the first plate portion 121a in a clearance fit with the first plate portion 121a. The second sub-shaft body 172 penetrates the second wall portion 131b and the second plate portion 121b, wherein the second sub-shaft body 172 penetrates the second wall portion 131b fixedly with the second wall portion 131b, and the second sub-shaft body 172 penetrates the second plate portion 121b in a clearance fit with the second plate portion 121b.

The first sub-shaft 171 may be a screw, and the first sub-shaft 171 passes through the first wall portion 131a in threaded connection with the first wall portion 131a. Likewise, the second sub-shaft 172 may be a screw, and the second sub-shaft 172 is threaded through the second wall 131b with the second wall 131b. In alternative embodiments, the first and second sub-shafts 171 and 172 may take the form of rivets.

Fig. 10 is a partially assembled perspective view of the cleaning device M6. Fig. 11 is a perspective view showing an embodiment of the brush holder 18, the escape restriction mechanism 19, and the rotation restriction mechanism 20 of the cleaning device M6, and fig. 12 is a front view of fig. 11. Fig. 13 is a perspective view showing another embodiment of the brush holder 18, the escape restriction mechanism 19, and the rotation restriction mechanism 20, and fig. 14 is a front view of fig. 13.

Since the brush holder 18, the escape restriction mechanism 19, and the rotation restriction mechanism 20 are combined together for use, the three will be described together. The brush holder 18 is provided with two channels C opening in a direction toward the brush sheet 161 on both sides in the X direction, respectively, and the brush holder 18 is fixedly connected to the movable bracket 13 in a direction away from the brush sheet 161. The shaft 163 of the ash brush 16 is disposed to be able to enter and exit the corresponding channel C of the brush holder 18 to pivotally connect the brush holder 18 to the brush housing 162. The escape restriction mechanism 19 is pivotally connected to the brush holder 18, and the escape restriction mechanism 19 has two restriction grooves S. The escape restriction mechanism 19 is provided: when the ash brush 16 is mounted, the escape restriction mechanism 19 is pivoted to a position where the restriction groove S accommodates the corresponding shaft lever 163 and intersects the corresponding channel C (in other words, the position of each shaft lever 163 is located on the pivot path of the corresponding restriction groove S) to prevent the corresponding shaft lever 163 from escaping from the corresponding channel C; when the ash brush 16 is detached, the escape restriction mechanism 19 is reversely pivoted so that each restriction groove S of the escape restriction mechanism 19 is reversely pivoted completely out of the corresponding shaft lever 163. The rotation limiting mechanism 20 is provided: when the escape restriction mechanism 19 is pivoted to a position where the restriction groove S accommodates the corresponding shaft lever 163 and intersects the restriction groove S with the corresponding channel C at the time of mounting the ash cleaning brush 16, the rotation restriction mechanism 20 fixes the escape restriction mechanism 19 and the brush holder 18 together and prevents the escape restriction mechanism 19 from pivoting relative to the brush holder 18; when the ash cleaning brush 16 is detached, the rotation restricting mechanism 20 releases the fixation of the escape restricting mechanism 19 and the brush holder 18 and allows the escape restricting mechanism 19 to pivot in the opposite direction with respect to the brush holder 18. The ash brush 16 can be easily attached and detached by the arrangement of the rotation restricting mechanism 20 and the escape restricting mechanism 19. Note that in fig. 2 and 3, one brush holder 18 directly connected to the connecting mechanism 11 does not employ the fixed holder 12, the movable holder 13, the pair of guide rods 14, and the coil spring 15, but the fitting adjustment of this brush holder 18 to the glass G is achieved by the other brush holder 18 employing the fixed holder 12, the movable holder 13, the pair of guide rods 14, and the coil spring 15 as shown in the drawings, which can simplify the structure. Of course, in alternative embodiments, the brush holder 18 may also be combined with the fixed holder 12, the movable holder 13, the guide bar pair 14, and the coil spring 15. In other words, the brush holder 18, the escape restriction mechanism 19, and the rotation restriction mechanism 20 may be used alone, or may be used in combination with the fixed bracket 12, the movable bracket 13, the guide rod pair 14, and the coil spring 15.

Specifically, in the example shown in fig. 11 to 14, the brush holder 18 includes two first side walls 181 and a second side wall 182. The two first side walls 181 are opposite to each other, and the second side wall 182 is connected between the two first side walls 181. The second side wall 182 is fixed to the second portion 132 of the movable bracket 13 with a wall surface in the thickness direction facing the second portion 132 fixed to the movable bracket 13, and preferably, the second side wall 182 protrudes toward the second portion 132 of the movable bracket 13 with respect to the two first side walls 181, so that the protruding portion is fixed to the second portion 132 of the movable bracket 13, thereby facilitating the fixation of the second side wall 182 and the second portion 132 of the movable bracket 13 in operation. Each first side wall 181 has a side edge 181a located on a side of each first side wall 181 remote from the second side wall 182, each first side wall 181 has a channel C that penetrates each first side wall 181 in the thickness direction of each first side wall 181 and extends from the first side edge 181a to the second side wall 182 and opens at the side edge 181 a. Each first side wall 181 is preferably flat

Specifically, in the example shown in fig. 11 to 14, the escape restriction mechanism 19 includes two first sheet bodies 191 and second sheet bodies 192. The two first sheets 191 are opposite to each other. The second sheet 192 is connected between the two first sheets 191. The first sheets 191 are juxtaposed and spaced (to ensure the smoothness of the pivoting of the release limiting mechanism 19 relative to the brush frame 18) on the outer side of the corresponding first sidewall 181, wherein one of the two first sheets 191 is close to the working stop position of the ash cleaning brush 16. Each first sheet 191 has an edge portion 191a intersecting the second sheet 192 and distant from the second portion 132 of the movable bracket 13. Each first sheet 191 has a restricting groove S. The restricting groove S penetrates each first sheet 191 in the thickness direction of each first sheet 191, extends from the edge portion 191a to the second portion 132 of the movable bracket 13, and opens at the edge portion 191a. Each first tab 191 is pivotally connected to a corresponding first sidewall 181 to enable the escape limiting mechanism 19 to be pivotally connected to the brush holder 18. Each of the first sheets 191 is preferably flat plate-shaped. In the example of fig. 11 to 14, the portion of the restricting slot S provided by each first sheet 191 is narrower than the other portions of each first sheet 191, so that the portion of the restricting slot S provided by each first sheet 191 and the other portions of each first sheet 191 form a notch 191c, and the provision of the notch 191c can reduce the distance by which the restricting slot S is pivoted out of and engages with the corresponding shaft 163, thereby reducing the size of each first sheet 191, and further reducing the overall size and occupied space of the escape restricting mechanism 19, thereby providing space for the extended function of the high cleaning apparatus M6.

To achieve the pivotal connection of the escape limiting mechanism 19, in the example shown in fig. 11 to 14, the escape limiting mechanism 19 further comprises two shaft portions 193. The two shaft portions 193 are axially opposite and spaced apart, and each shaft portion 193 penetrates through a corresponding first sheet 191 and a first side wall 181, wherein each shaft portion 193 and the corresponding first sheet 191 fixedly penetrate through the corresponding first sheet 191, and each shaft portion 193 and the corresponding first side wall 181 penetrate through the corresponding first side wall 181 in a clearance fit.

The rotation limiting mechanism 20 is preferably mounted near the work stop position. The operator can operate the rotation limiting mechanism 20 from the outside of the work stop position, thereby improving the operational convenience and work efficiency of the operator, and avoiding the limitation in space of operating the rotation limiting mechanism 20 from the inside of the work stop position. The rotation limiting mechanism 20 is provided: when the ash cleaning brush 16 is installed, the rotation limiting mechanism 20 penetrates through the corresponding adjacent first sheet 191 and the first side wall 181 and fixes the corresponding adjacent first sheet 191 and the first side wall 181, wherein the rotation limiting mechanism 20 fixedly penetrates through the corresponding first side wall 181 with the corresponding first side wall 181, and the rotation limiting mechanism 20 penetrates through the corresponding first sheet 191 in a clearance fit with the corresponding first sheet 191; when the ash brush 16 is detached, the rotation restricting mechanism 20 is removed from the first side wall 181 to enable the escape restricting mechanism 19 to rotate about the axis of the two shaft portions 193, so that the restricting grooves S of the two first sheet bodies 191 are respectively disengaged from the two shaft levers 163.

The rotation limiting mechanism 20 may take a variety of suitable forms. In the example shown in fig. 11 and 12, the rotation limiting mechanism 20 is a screw, each first sheet 191 is provided with a waist hole 191b, and the screw is provided with: when the ash brush 16 is installed, the screws pass through the waist holes 191b of the corresponding first sheet bodies 191 and fasten the first sheet bodies 191 and the first side walls 181 together, wherein the screws pass through the first side walls 181 in a threaded manner but pass through the corresponding first sheet bodies 191 in a clearance fit manner; upon removal of the brush 16, the screw is loosened from the first sidewall 181 and no removal is required so that the screw can move along the waist hole 191b and the removal limiting mechanism 19 can pivot about the axis of the shaft portion 193 relative to the brush holder 18. In the example shown in fig. 13 and 14, the rotation limiting mechanism 20 is a spring pin including a built-in coil spring (not shown) and a shaft pin 201 passing through the coil spring, and the rotation limiting mechanism 20 is provided so that: when the ash cleaning brush 16 is installed, the pin 201 is pressed from the outside, so that the pin 201 passes through the corresponding adjacent first sheet 191 and first side wall 181 and the pin 201 is fixedly connected with the first side wall 181; when the ash brush 16 is detached, the pin 201 is pulled out from the outside to disengage the pin 201 from the first side wall 181, thereby enabling the escape restriction mechanism 19 to pivot about the shaft portion 193 with respect to the brush holder 18. Whether in the form of a screw or a helical spring pin, the rotation limiting mechanism 20 does not need to be completely detached, so that the efficiency of mounting and detaching the ash cleaning brush 16 is improved, and the working efficiency of the color selector is further improved.

Fig. 15 shows the arrangement of the dust deflector brush 21 and the nozzle plate brush 22 of the cleaning device M6.

As shown in fig. 15, the connection mechanism 11, the fixed bracket 12, the movable bracket 13, the guide bar pair 14, the coil spring 15, and the ash brush 16 are mirror-symmetrical in structure with respect to a center plane 113 perpendicular to the X direction, and the two ash blocking plate brushes 21 are mirror-symmetrically installed on opposite sides of the connection mechanism 11 (specifically, for example, the installation base 111, but not limited thereto, an appropriate portion or member of the connection mechanism 11 may be selected depending on actual needs), and the two nozzle plate brushes 22 are mirror-symmetrically installed on opposite sides of the connection mechanism 11 with respect to the center plane 113. In other words, the brush 16 is located in the middle of the two plate brushes 21 in the X direction (similarly, the brush 16 is located in the middle of the two plate brushes 22 in the X direction. The plate brushes 21 are used for cleaning the accumulated material on the plate brushes M5. The plate brushes 22 are used for cleaning the accumulated material on the plate in the nozzle device. In this way, the cleaning device M6 is in a symmetrical state (i.e. symmetrical structure) with respect to the center plane 113 in the moving direction (i.e. along the X direction), the cleaning device M6 can maintain the balance left and right during the cleaning process, and the single side weight caused by the single side arrangement is avoided, thereby the left and right shake, inclination and shake of the cleaning device M6 in the cleaning motion direction during the cleaning process are avoided, so that the operation stability of the cleaning process is improved, and the cleaning efficiency and cleaning effect are improved by adopting the two plate brushes 21 and the two plate brushes 22.

Finally, the cleaning device M6 according to the invention can be used alone or in any other way, without being limited to a color sorter, as long as the particular corresponding components of the color sorter (for example, the dust deflector brush 21 and the nozzle plate brush 22) are removed.

The above detailed description describes various exemplary embodiments, but is not intended to be limited to the combinations explicitly disclosed herein. Thus, unless otherwise indicated, the various features disclosed herein may be combined together to form a number of additional combinations that are not shown for the sake of brevity.
