Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will recognize without departing from the spirit and scope of the present invention.

The glass plate is conveyed into the heating furnace through a conveying mechanism such as a ceramic roller and the like and heated to be softened, then conveyed to the bending die to enable the softened glass plate to be formed into a required curved surface shape, finally conveyed between two opposite tempering air grids, and sprayed with high-speed low-temperature air flow towards the glass plate through the opposite tempering air grids to cool and temper the glass plate. Because the toughened glass has different curvatures in different use scenes, and in the actual production process, when the toughened air grid is used for cooling and toughening the glass plate, the angle error between the trajectory of the high-speed low-temperature air flow jetted by the toughened air grid and the curved surface of the glass plate is required to be within 0-15 degrees. Traditional tempering air grid is not strong to the toughened glass's of different curvatures adaptability, leads to the toughened glass of different curvatures to need be equipped with different tempering air grids, has not only increased toughened glass's manufacturing cost, and a large amount of tempering air grids need occupy a large amount of storage space moreover, are unfavorable for the production dispatch.

As shown in fig. 1, in one embodiment, a tempered air grid is provided, which includes an air box 500 and at least two air outlet units 10. The wind box 500 is used for supplying high-speed low-temperature airflow to each air outlet unit 10 to cool and temper a glass plate (not shown). And, two at least air-out units 10 can cooperate and form the air-out array with the profile assorted of glass board, satisfy the cooling tempering requirement of glass board.

As shown in fig. 1 and fig. 2, optionally, the air outlet unit 10 includes an air guiding duct 100, an air outlet head 200 and at least one expansion piece 300.

The air guide tube 100 may be made of flexible and stretchable materials such as silica gel or rubber, so that the air guide tube 100 can perform telescopic movement along a first preset direction (as shown in a direction a of fig. 2).

It should be noted that, the first preset direction may be any direction suitable for processing and producing tempered glass, for convenience of explaining the principle of the embodiment of the present application, the two tempering air grids are oppositely disposed in an up-down relationship, and the first preset direction is exemplified by a vertical direction, which is not to be understood as a limitation or limitation of the embodiment of the present application.

Wherein, the air outlet head 200 can be plate-shaped or block-shaped. The air outlet head 200 can be connected with one end of the air guide pipe 100 in a clamping, inserting and other modes, so that the air outlet 210 on the air outlet head 200 is communicated with the air guide pipe 100, high-speed low-temperature airflow flows out from the air box 500, flows out from the air outlet 210 after being guided by the air guide pipe 100 and finally blows towards the glass plate to cool and toughen the glass plate.

Specifically, the air outlet head 200 includes an air outlet surface disposed toward the glass plate, and at least two air outlets 210 disposed at an interval are disposed on the air outlet surface. The air duct 100 is located on the side of the air outlet head 200 departing from the glass plate.

Wherein, each expansion piece 300 all is equipped with the flexible end 310 that can follow vertical direction reciprocating motion, moreover, each flexible end 310 all rotates with air-out head 200 to be connected. Thus, the retractable end 310 is utilized to reciprocate along the vertical direction, so as to drive the air outlet head 200 to reciprocate along the vertical direction. Moreover, the air outlet head 200 can also rotate around the corresponding rotation axis relative to the telescopic end 310.

In addition, the outtake head 200 can be operatively rotated relative to the telescoping end 310. Therefore, under the action of the force, the air outlet head 200 can rotate around the corresponding rotation axis relative to the telescopic end 310, and then the position of the air outlet head 200 relative to the telescopic end 310 is adjusted.

Furthermore, the air outlet head 200 can be locked at any rotation position relative to the telescopic end 310 in an unoperated state. So when rotating the relative flexible end 310 of the first 200 of going out to suitable position, the first 200 of going out can stretch out and draw back relatively and hold 310 locking in this position, and the relative flexible end 310 takes place to remove or rotate when avoiding the air outlet 210 on the first 200 of going out to spray high-speed low temperature air current, guarantees that the surface of spraying to the glass board that high-speed low temperature air current can be accurate.

The air-out unit 10 of above-mentioned embodiment, when the camber of glass board changes, through the flexible end 310 along the flexible of vertical direction, thereby drive out first 200 along vertical direction motion, and simultaneously, can also make out first 200 relative flexible end 310 rotations of wind under the exogenic action, thereby can further adjust out the position of first 200 of wind, and then make out the trajectory of the high-speed low temperature air current that air outlet 210 department on the first 200 of wind and locate the ejection perpendicular to glass board place curved surface or air outlet 210 department and the angular error between the high-speed low temperature air current's that jets trajectory and glass board place curved surface within 0 ~ 15, thereby can adapt to the camber change of glass board, the commonality of tempering air grid has been strengthened. The production requirements of toughened glass with different curvatures can be met by using one toughened air grid, so that the production cost is reduced, the storage space is saved, and the production scheduling is facilitated.

It should be noted that the trajectory of the high-speed low-temperature airflow ejected from the air outlet 210 is perpendicular to the curved surface where the glass plate is located, and may be the trajectory of the high-speed low-temperature airflow ejected from the air outlet 210 extending along the normal direction of the curved surface corresponding to the glass plate, so as to ensure that the high-speed low-temperature airflow can sufficiently cool and toughen the glass plate. The angle error between the trajectory of the high-speed low-temperature airflow ejected from the air outlet 210 and the curved surface of the glass plate may be an included angle between the trajectory of the high-speed low-temperature airflow ejected from the air outlet 210 and the normal of the curved surface of the glass plate.

Wherein, flexible end 310 is connected with the rotation of air-out head 200, can adopt the pivot to connect or articulated mode such as go on, only need satisfy air-out head 200 can stretch out and draw back end 310 relatively when the atress effect and rotate in order to adjust the position, can stretch out and draw back end 310 locking in this position relatively after adjusting to suitable position can.

In addition, the rotation of the air outlet head 200 relative to the telescopic end 310 in the operated state can be achieved by applying an external force (e.g., a pulling force) to the air outlet head 200.

In addition, the air outlet head 200 can be locked at any rotation position relative to the telescopic end 310 in an unoperated state, and the locking of the air outlet head 200 and the telescopic end 310 can be realized by arranging a locking element such as a lock pin, and the like, and the friction force of the connection part of the air outlet head 200 and the telescopic end 310 can also be utilized.

Optionally, the telescopic end 310 and the air outlet head 200 are rotatably connected through a universal joint, so that the air outlet head 200 can rotate relative to the telescopic end 310 under the action of external force, the clamping cannot occur, and the telescopic end 310 can be locked at a proper position after being rotated to the proper position.

Optionally, the telescopic end 310 and the air outlet head 200 are rotatably connected through a ball hinge, so that the air outlet head 200 can rotate relative to the telescopic end 310 under the action of external force, the rotation is smooth, and the relative telescopic end 310 can be locked at a proper position under the action of friction force after the air outlet head 200 rotates to the proper position.

The air box 500 is communicated with one end of each air guiding pipe 100 far away from the air outlet head 200 in a sleeving or splicing manner. Even if the expansion piece 300 drives the air outlet head 200 to move along the vertical direction, the high-speed low-temperature airflow can be smoothly supplied to the air outlet 210 of the air outlet head 200 by utilizing the deformation expansion of the air guide pipe 100. The wind box 500 may further include an air outlet connector coupled to the air guide pipe 100.

The telescopic member 300 may be an electric cylinder, a hydraulic cylinder, an air cylinder, or other elements capable of achieving the telescopic function. The telescoping end 310 may be a rod or the like.

In order to facilitate the installation and connection between the air guide duct 100 and the air outlet head 200, the air leakage at the connection part between the air guide duct 100 and the air outlet head 200 is avoided.

As shown in fig. 2, optionally, the air outlet unit 10 further includes a first mounting member 400. The first mounting member 400 is provided with a first mounting through hole 410, so that one end of the air duct 100 can be mounted in the first mounting through hole 410 by means of plugging or clamping. And, one side that deviates from the air-out face at air-out head 200 is equipped with the air intake (not shown) that communicates with air outlet 210, can set firmly air-out head 200 on first installed part 400 with modes such as spiro union, welding, make one side that air-out head 200 deviates from the air-out face laminate with first installed part 400 each other, and make the air intake correspond the intercommunication with first installation through-hole 410, thereby realize the intercommunication of guide duct 100 and air intake, and then can avoid taking place gas leakage.

In addition, flexible end 310 rotates with first installed part 400 to be connected to make flexible end 310 when along vertical direction concertina movement, can drive first installed part 400 and remove along vertical direction, and then drive out first 200 and remove along vertical direction. And, under the external force effect, first installed part 400 and air-out head 200 all can rotate in order to adjust the position of air-out head 200 relative telescopic end 310, and when air-out head 200 adjusted to suitable position, air-out head 200 and first installed part 400 also can lock in this position relative telescopic end 310 in step.

Wherein the first mount 400 may be in the form of a mounting plate or mount.

The departure head can be connected to at least two air outlets 210 via an air inlet.

The rotational connection between the telescopic end 310 and the first mounting member 400 can also be realized by a universal joint or a ball hinge.

In addition, the second mounting through hole can guide the expansion and contraction of the air guide pipe 100, and the air guide pipe 100 is prevented from being wound or knotted.

Wherein the second mount may be in the form of a mounting plate or mount. The second mount may be disposed opposite to the first mount 400 in a vertical direction at a distance.

The first mounting end can be in the form of a machine body or a machine base, and can also be in the form of a cylinder body.

In order to make the rotation of the air outlet head 200 relative to the telescopic end 310 more flexible and the rotation amplitude larger, it can also be realized by increasing the moving stroke of the air outlet head 200 along the vertical direction.

Optionally, the air outlet unit 10 further includes at least one auxiliary jacking mechanism 700. Each auxiliary jacking mechanism 700 can perform jacking movement along the vertical direction. Wherein each telescoping member 300 is provided with a second mounting end 320 spaced opposite the telescoping end 310. And, at least a part of the second mounting ends 320 are connected with at least one auxiliary jacking mechanism 700 in a screw joint, clamping joint or the like in a one-to-one correspondence manner. So, flexible end 310 of extensible member 300 drives out first 200 removal of wind and accomplishes the back along vertical direction, the jacking motion that can utilize supplementary climbing mechanism 700 drives extensible member 300 wholly and further removes along vertical direction, and then can drive out first 200 and further remove along vertical direction, the ascending removal stroke of air-out head 200 in vertical direction has been increased, thereby can further increase the rotation range of the relative flexible end 310 of air-out head 200, and then the position of the adjustment air-out head 200 that can be more nimble, can adapt to the bigger camber change of glass board, the commonality of tempering air grid has further been strengthened.

It should be noted that, at least a part of the second mounting ends 320 are connected to at least one auxiliary jacking mechanism 700 in a one-to-one correspondence manner, which means that part of the second mounting ends 320 of the telescopic members 300 are connected to the auxiliary jacking mechanisms 700 in a one-to-one correspondence manner, while the other part of the second mounting ends 320 of the telescopic members 300 are not connected to the auxiliary jacking mechanisms 700 in a corresponding manner, that is, the number of the auxiliary jacking mechanisms 700 is less than the number of the telescopic members 300; the second mounting ends 320 of all the telescopic members 300 may be correspondingly connected to the auxiliary jacking mechanisms 700, that is, the number of the auxiliary jacking mechanisms 700 is the same as that of the telescopic members 300.

The second mounting end 320 may be in the form of a body or a base, or may be in the form of a cylinder.

The jacking movement of the auxiliary jacking mechanism 700 may be realized in a telescopic manner, for example, the auxiliary jacking mechanism 700 may be a jacking cylinder or a jacking hydraulic cylinder; the lifting movement of the auxiliary lifting mechanism 700 may also be achieved by a rotation manner, for example, the rotation of the cam pushes against the telescopic member 300 to move in the vertical direction; the lifting movement of the auxiliary jacking mechanism 700 may also be achieved by turning, for example, the turning of the turning table drives the telescopic member 300 to move in the vertical direction.

Optionally, the auxiliary jacking mechanism 700 includes a turning member 710 capable of turning in a vertical direction, and the turning member 710 is connected with the second mounting end 320 in a clamping manner, a screwing manner, or the like. So, the flexible end 310 of extensible member 300 drives out wind head 300 and stretches out and draws back along vertical direction, upset piece 710 can be in step at vertical orientation go up the upset, and then make extensible member 300 whole can further remove along vertical direction, thereby further increased the ascending removal stroke of wind-out head 200 in vertical direction, thereby can further increase the rotation range of the relative flexible end 310 of wind-out head 200, and then the position of the wind-out head 200 of adjustment that can be more nimble, can adapt to the bigger curvature change of glass board, the commonality of tempering air grid has further been strengthened.

It should be noted that, the flip 710 can be flipped in the vertical direction, which means that the flipping axis of the flip 710 is perpendicular to the vertical direction.

The specific number of the turnover members 710 can be flexibly adjusted or selected according to actual use requirements. Wherein, the flipping axis refers to a rotation axis around which the flipping member 710 rotates. Optionally, there are three telescopic members 300, two turning members 710, the second mounting ends 320 of the first and second telescopic members 300 are correspondingly connected to the two turning members 710, and the second mounting end 320 of the third telescopic member 300 is fixed to an external fixing position such as the bellows 500. So, first and second extensible member 300 are flexible, two upset pieces 710 that correspond can overturn in step, make first and second extensible member 300 can drive out first 200 removals longer distances in vertical direction, and third extensible member 300 drives out first 200 migration distances shorter relatively in vertical direction, make the displacement difference of the different sides of play first 200 in vertical direction bigger, and then make the inclination of the relative horizontal plane of play first 200 bigger.

In addition, the extending directions of the turning axes of the turning pieces 710 can be the same or different, and the turning pieces can be designed according to actual use requirements.

Alternatively, the second mounting ends 320 of the first and second telescopic members 300 are connected to the two turning members 710 in a one-to-one correspondence, the second mounting end 320 of the third telescopic member 300 is fixed to an external fixing position such as the bellows 500, and the turning axis of the turning member 710 connected to the first telescopic member 300 is perpendicular to the turning axis of the turning member 710 connected to the second telescopic member 300. Thus, when one of the turning members 710 is turned, the other turning member 710 remains still, and the turning of the turning member 710 and the corresponding extension and retraction of the telescopic end 310 of the telescopic member 300 are combined, so that the angle of inclination of the outlet head 200 with respect to the horizontal plane can reach 90 °.

Optionally, the second mounting ends 320 of the first and second telescopic members 300 are connected to the two turning members 710 in a one-to-one correspondence, the second mounting end 320 of the third telescopic member 300 is fixed to an external fixed position such as the bellows 500, and the turning axis of the turning member 710 connected to the first telescopic member 300 is in any direction, that is, the turning member 710 connected to the first telescopic member 300 is rotated in a universal direction, and the turning axis of the turning member 710 connected to the second telescopic member 300 is in any direction, that is, the turning member 710 connected to the second telescopic member 300 is also rotated in a universal direction. Thus, when one of the turning members 710 is turned, the other turning member 710 can be driven to link, so that the angle of inclination of the air-out head 200 relative to the horizontal plane can reach about 29 °.

Wherein, the upset of upset piece 710 can be the form that upset seat 711 and roll-over table 712 rotate to be connected, and form such as spiro union or joint can be adopted to roll-over seat 711 and set firmly on bellows 500, and form such as spiro union or joint can be adopted to second installation end 320 and set firmly on roll-over table 712 to can drive extensible member 300 when making the relative roll-over seat 711 upset of roll-over table 712 and remove along vertical direction.

Wherein, bellows 500 can set up the one side that deviates from first installed part 400 at the second installed part, and the form that bellows 500 and guide duct 100 directly communicate guarantees that wind-force can not take place a large amount of attenuations, is favorable to the cooling tempering of glass board.

Wherein, the number of extensible member 300 in every air-out unit 10 can carry out nimble design or adjustment according to actual in service behavior, for example, every air-out unit 10 can use one, two, three or more extensible member 300, only need satisfy can carry out the adjustment of adaptability to the height of the relative bellows 500 of air-out head 200 and the inclination of the relative bellows 500 of air-out head 200, can adapt to the curvature change of glass sheet.

In addition, when each air outlet unit 10 includes at least two telescopic members 300, each telescopic member 300 can be independently operated, so that the height of the air outlet head 200 relative to the bellows 500 and the inclination angle of the air outlet head 200 relative to the bellows 500 can be adaptively adjusted to adapt to the curvature change of the glass sheet.

Wherein, three extensible member 300 is triangle-shaped interval setting to, three flexible end 310 all is connected with the rotation of air-out head 200. Thus, when the telescopic ends 310 of the three telescopic members 300 are synchronously telescopic, the air outlet head 200 can be driven to ascend or descend along the vertical direction. Also, when there is a difference in the length of expansion and contraction between the respective expansion and contraction ends 310, the inclination angle of the wind-out head 200 with respect to the wind box 500 can be adjusted to accommodate the change in curvature of the glass sheet.

Optionally, there are two telescopic members 300 of one air outlet unit 10. Wherein, two extensible member 300 intervals set up to, two flexible end 310 all rotate with air-out head 200 and be connected. Thus, when the telescopic ends 310 of the two telescopic members 300 are synchronously telescopic, the air outlet head 200 can be driven to ascend or descend along the vertical direction. Also, when there is a difference in the length of extension and contraction between the two extension and contraction ends 310, the inclination angle of the wind-out head 200 with respect to the wind box 500 can be adjusted to accommodate the change in curvature of the glass sheet.
