Description
Technical Field
The invention relates to the field of cloth processing equipment, in particular to a cloth feeding machine.
Background
In the production process of cloth, the fabric needs to be sent to a printer through a cloth feeding machine and printed with a surface pattern in the printer. In order to facilitate the relationship between the cloth feeding speed of the cloth unwinding machine and the cloth pulling speed of the printer, the cloth feeding speed is further adjusted to ensure that the cloth feeding speed is matched with the cloth pulling speed, and a floating roller needs to be arranged between the cloth feeding machine and the printer. The floating roller is pressed on the cloth vertically to the cloth feeding direction, then the cloth is pressed by the gravity of the floating roller, when the cloth pulling speed of the printer is increased in the production process, a large pulling force is applied to the cloth to enable the floating roller to be increased, and at the moment, the cloth feeding speed needs to be increased; when the cloth pulling speed is reduced, the pulling force on the cloth is reduced so as to lower the floating roller, and the cloth feeding speed needs to be reduced at the moment. Therefore, the change of the cloth drawing speed of the printer and the relation between the cloth drawing speed of the printer and the cloth feeding speed of the cloth feeding machine are known by observing the ascending and descending of the floating roller, so that a reference basis is provided for the adjustment of the cloth feeding speed. However, the variation of the cloth spreading speed of the cloth spreading machine according to the requirements of the production process has great randomness, and the weight of the floating roller is fixed, so that the highest point and the lowest point of the floating roller and the ascending-descending stroke of the floating roller in different printing procedures have great variation, great trouble is brought to observation and monitoring, and the adjustment of the cloth feeding speed is not facilitated.

For example, when the position of the stroke midpoint is always higher, the cloth pulling speed is always at a relatively higher level, and the cloth feeding speed level can be comprehensively increased on the original basis; when the position of the stroke middle point is lower all the time, the cloth pulling speed is lower all the time, and the cloth feeding speed level of the cloth feeding machine in the whole production process can be adjusted lower on the original basis.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present; when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 and 5, in an embodiment of the present invention, there is provided a cloth feeding machine 1 including a dancer roller stroke adjusting device including:
the transmission chain assembly 110 is arranged up and down, and the transmission chain assembly 110 is connected with the floating roller 10 so that the transmission chain assembly 110 can synchronously rotate under the driving of the floating roller 10;
a timing belt assembly 120 coupled with the drive chain assembly 110 to be interlocked with the drive chain assembly 110;
and a damping driving member 130 connected to the timing belt assembly 120 to provide a damping force opposite to a moving direction of the timing belt assembly 120.
In the figure, a cloth is fed into the cloth feeding machine 1 via a cloth feeding roller 30, guided by parallel guide rollers in the cloth feeding machine 1, moved in the direction indicated by the arrow, and finally passed around a floating roller 10 and fed forward to a printer via a feed-out roller 40. In the working process, when the cloth pulling speed of the printer is increased, the cloth pulling force is increased so as to support the floating roller 10 and enable the position of the floating roller to be increased, the rising floating roller 10 drives the transmission chain assembly 110 to rotate, the transmission chain assembly 110 drives the synchronous belt assembly 120 to move while rotating, at the moment, the damping driving component 130 provides damping force to enable the rising speed of the floating roller 10 to be reduced until the floating roller 10 stops rising, so that the height of the floating roller which rises to the highest point is reduced, and the rising position is prevented from being too high; when the cloth pulling speed of the printer is reduced, the cloth pulling force is reduced, so that the position of the floating roller 10 is reduced, the lowered floating roller 10 drives the transmission chain assembly 110 to rotate reversely, the transmission chain assembly 110 drives the synchronous belt assembly 120 to move reversely while rotating reversely, at the moment, the damping driving component 130 provides damping force to slow down the lowering speed of the floating roller 10 until the floating roller 10 stops lowering, so that the height of the lowest point reached by the lowering is increased, and the lowering position is prevented from being too low.
By implementing the process, the variation of the highest point and the lowest point of the floating roller 10 and the ascending stroke and the descending stroke of the floating roller 10 in the printing process is small, so that the observation and the monitoring of the position of the floating roller 10 are greatly facilitated, and the adjustment of the cloth feeding speed to be matched with the cloth pulling speed is facilitated.
The damping driving component 130 does not directly drive the transmission chain component 110, so as to prevent the transmission chain component 110 from being frequently applied with force to generate large stress and shorten the service life of the transmission chain component 110; the transmission chain assembly 110 is linked with the synchronous belt assembly 120, and the damping driving component 130 applies force to the synchronous belt assembly 120, so that the large stroke range of the floating roller can be controlled and adjusted.
In some embodiments, the drive chain assembly 110 is provided at the end of the dancer 10. Specifically, the transmission chain assembly 110 can be installed on the side surface of the cloth feeding machine 1, the side surface of the cloth feeding machine 1 is provided with a guide groove 1-1, and the end part of the floating roller 10 is arranged in the guide groove 1-1 and can move up and down along the guide groove 1-1. The installation operation is facilitated by adopting the arrangement mode. In other embodiments, the drive chain assembly 110 may be disposed in the middle of the dancer 10, and is not limited thereto.
Referring to fig. 5, in some embodiments, the driving chain assembly 110 includes two driving sprockets 111 disposed one above the other and a driving chain 112 for driving the two driving sprockets 111, and the end of the dancer roller 10 is connected to the driving chain 112. The structure is simple in design and convenient to implement and install. In other embodiments, the drive chain assembly 110 includes three or more sprockets and a drive chain 112 encircling the sprockets, without limitation.
In some embodiments, the end of the dancer 10 is connected to the drive chain 112 via a fixed block 11. The mode of connecting through fixed block 11 can avoid direct connection to form the damage to drive chain 112.
In some embodiments, the device further comprises guide posts 12 arranged up and down, and the guide posts are slidably matched with the fixing block 11 so that the fixing block 11 can slide along the length direction of the guide posts 12. The guide post 12 has a guiding function, so that the fixed block 11 and the floating roller 10 can be ensured to move vertically all the time, and the position deviation caused by long service time is avoided.
With continued reference to fig. 5, in some embodiments, the timing belt assembly 120 includes two pulleys 121 and a belt 122 looped around the two pulleys 121. The structure is simple in design and convenient to implement and install. In other embodiments, the timing belt assembly 120 includes three or more pulleys 121 and a belt 122 wound around the pulleys 121, which is not limited herein. Preferably, the belt body 122 is a flat belt.
In some embodiments, two pulleys 121 are coaxially disposed with the two drive sprockets 111, respectively. In this embodiment, the two belt pulleys 121 are respectively coaxially disposed with the two transmission chain wheels 111, so that the installation space of the whole device can be saved, the arrangement length of the transmission chain assembly 110 can be extended, and the control and adjustment of a large stroke range are facilitated. In other embodiments, one of the two pulleys 121 is disposed coaxially with one of the two driving sprockets 111, and may be coupled to the driving chain assembly 110 for linkage, which is not limited herein.
In some embodiments, the damping driving member 130 is a telescopic rod 131, the extension direction of the telescopic rod 131 is parallel to the moving direction of the timing belt assembly 120, and the end of the telescopic rod 131 is connected to the timing belt assembly 120. When the timing belt assembly 120 moves, a damping force is generated in the telescopic rod 131 to decelerate the timing belt assembly 120 until the timing belt assembly 120 stops moving, so that the floating roller 10 synchronously stops moving up and down. Preferably, the extension rod 131 is a cylinder. Specifically, the air cylinder may be controlled to pressurize by a fine pressure regulating valve to generate a damping force, and applying a resistance force to the dancing roll 10 by the timing belt assembly 120 reduces the moving speed until stopping, which corresponds to changing the weight of the dancing roll 10. In other embodiments, the extension rod 131 may be an electric extension rod 131 or a hydraulic cylinder, which generates the damping force by current variation and hydraulic pressure application, respectively, without limitation.
In some embodiments, the end of telescoping rod 131 is slidably disposed on a guide rod 132 that is parallel to telescoping rod 131. The guide rod 132 has a guiding function, so that the telescopic rod 131 can be ensured to be telescopic along the extending direction of the telescopic rod all the time, and the telescopic direction of the telescopic rod can be prevented from being deviated for a long time.
In some embodiments, the end of the telescopic rod 131 is provided with a clamping body 133, and the clamping body 133 clamps the timing belt assembly 120. Specifically, the clamping body 133 can clamp the strap 122. In this embodiment, the clamping manner can avoid the use of fasteners such as bolts to directly connect the clamping body 133 with the belt body 122, which can reduce the surface damage to the belt and prolong the service life; and the clamping body 133 directly clamps the band 122, thereby preventing the band 122 from being deformed.
In some embodiments, further comprising:
a position detection unit for detecting the position of the dancer roller 10;
and the control unit is in communication connection with the position detection unit and the cloth feeder 1 and is used for adjusting the cloth feeding speed of the cloth feeder 1 according to the position information of the floating roller 10 detected by the position detection unit.
When the position detection unit detects that the position of the floating roller 10 is lifted, the cloth spreading speed of the cloth spreading machine is increased, and the control unit controls and increases the cloth feeding speed of the cloth feeding machine 1 to enable the cloth feeding speed to be matched with the cloth spreading speed; when the sensor detects a decrease in the position of the dancer roll 10, indicating that the spreading speed of the spreader is decreasing at that time, the control unit controls to slow down the feed speed of the spreader 1 to match the spreading speed. Therefore, the purpose of assisting in adjusting the cloth feeding speed in real time is achieved by using the embodiment, and compared with a method for manually adjusting the cloth feeding speed, the method does not need to be watched in real time and is convenient to operate; more importantly, the safety accident caused by the collision between the position of the floating roller 10 which is too high or too low and other components on the cloth feeding machine 1 due to carelessness and failure to manually adjust the speed of the cloth feeding machine 1 in time can be avoided.
Preferably, the position detecting unit is a displacement sensor, and is disposed on the driving chain assembly 110. Specifically, the displacement sensor can select an absolute value encoder, and can be arranged on a transmission chain wheel 111 of the transmission chain assembly 110, because the transmission chain wheel 111 synchronously rotates under the driving of the floating roller 10, when the displacement sensor detects the change of the rotation position of the transmission chain wheel 111, the change of the horizontal position of the floating roller 10 is indicated, that is, the change of the horizontal position of the floating roller 10 can be reflected by detecting the change of the rotation position of the transmission chain wheel 111.
Further, the control unit is communicatively coupled to the damping drive component 130. When the control unit judges that the position detection unit detects that the horizontal position of the floating roller 10 changes too much, the control unit increases the damping force of the damping driving part 130 to stop the floating roller 10 from moving in the shortest time to prevent the position of the floating roller 10 from rising too high or falling too low to collide with other parts on the cloth feeding machine 1 and further cause safety accidents.
During actual cloth feeding, the fact that the surfaces of a plurality of pieces of cloth are uneven and easily wrinkled is found, and subsequent printing is influenced; in addition, the cloth fed by the cloth feeder 1 is easy to deviate from the standard cloth feeding direction, which is inconvenient to store the cloth, and the direction fed into the printer by the cloth feeder 1 is also deviated, so that the printed pattern is inclined and the quality of the printed pattern does not reach the standard. To this end, with reference to fig. 3, in some embodiments, the cloth feed machine 1 further comprises:
the cloth releasing device 50 is arranged on the cloth feeding machine 1 adjacent to the cloth feeding roller 30 of the cloth feeding machine 1, and the axis of the cloth releasing device 50 is parallel to the axis of the cloth feeding roller 30.
The cloth discharger 50 can discharge the cloth in a rotating manner. Put cloth ware 50 and cloth feeding roller 30 of cloth feeding machine 1 adjacent locate cloth feeding machine 1, and the axis of putting cloth ware 50 is parallel with the axis of cloth feeding roller 30, can guarantee to put the direction that cloth ware 50 played the cloth and be completely perpendicular to cloth feeding roller 30, the direction of cloth input cloth feeding machine 1 can remain stable to reduce the probability that the cloth direction that sends into the printer through cloth feeding machine 1 appears the skew in the source, and the cloth that comes out from cloth feeding machine 1 also is difficult for appearing the fold.
In the embodiment, the cloth feeding direction is consistent with the preset direction, the cloth feeding direction is vertical to the width direction of the cloth, and the cloth can be directly wound into a standard cloth roll after being fed out; on the other hand, the subsequent cloth feeding direction of the printer is kept stable, and the situation that the printed pattern is inclined can not occur. Because the cloth from the cloth feeding machine 1 is not easy to wrinkle, the cloth can be printed with patterns with better quality after subsequently entering a printer.
In order to meet various actual use requirements, the cloth placing frame 60 can be arranged beside the cloth feeding machine 1, the cloth amount which can be wound by the cloth placing frame 60 is larger, and the requirement of batch cloth feeding and printing can be met. When the number of the processed cloth is less, the cloth is directly released by the cloth releasing device 50.
During the use of the cloth feeder 1, it is found that the cloth fed out of the cloth feeder 1 is not smooth enough and that the cloth fed out of the cloth feeder 1 still has a certain probability of deviating from the standard cloth feeding direction. To this end, with reference to fig. 1, in some embodiments, the cloth feeder 1 further comprises:
a feed roller 20 rotatably provided in the cloth feeder 1;
the limiting structure comprises two limiting plates 210 which are oppositely arranged at two ends of the sending-out roller 20, each limiting plate 210 comprises a fixed end 211 and a movable end 212 which can swing around the fixed end 211 in the width direction of the cloth feeding machine 1, the horizontal heights of the fixed ends 211 of the two limiting plates 210 are equal, the movable ends 212 of the two limiting plates 210 are connected, and the distance between the movable ends 212 of the two limiting plates 210 is greater than that between the fixed ends 211 of the two limiting plates 210;
the leveling component 300 comprises a rotary connecting piece 310 which is arranged on the surface of one side of the two limiting plates 210 opposite to each other and is sleeved on the delivery roller 20, and a cloth spreading component 320 which is distributed on the circumferential surface of the delivery roller 20 and can slide along the axial direction of the delivery roller 20, wherein two ends of the cloth spreading component 320 along the axial direction of the delivery roller 20 are respectively connected with the rotary connecting piece 310 on the corresponding side;
and a driving member 400 connected to one of the two stopper plates 210 to drive the stopper plate 210 to swing about the fixed end 211 thereof.
As shown in fig. 1, since the distance between the movable ends 212 of the two limiting plates 210 is greater than the distance between the two fixed ends 211, that is, the two limiting plates 210 are respectively inclined to the outer side of the cloth feeding machine 1 by using the fixed ends 211 as hinge points, since the rotary connecting member 310 is installed on the limiting plate 210, the upper part of the rotary connecting member 310 is also inclined to the outer side of the cloth feeding machine 1 together with the limiting plate 210, that is, the distance between the upper parts of the two rotary connecting members 310 is greater than the distance between the lower parts of the two rotary connecting members 310. The cloth is guided into the cloth feeding machine 1 through the cloth feeding roller 30 and spread on the cloth spreading component 320 on the surface of the cloth feeding roller 20 along the circumferential direction, the cloth feeding roller 20 is driven to rotate so as to feed the cloth forwards, and because the two ends of the cloth spreading component 320 along the axial direction of the cloth feeding roller 20 are respectively connected with the rotary connecting pieces 310 on the corresponding sides, when the cloth feeding roller 20 rotates, the part of the cloth spreading component 320 on the outer circumferential surface of the upper part of the cloth feeding roller 20 slides towards the two ends of the cloth feeding roller 20 along the axial direction of the cloth feeding roller 20, and the cloth spread on the surface of the cloth is spread and kept flat along the width direction through the friction force generated by the contact with the surface of the cloth; since the spreading members 320 and the delivery roller 20 are rotatable together, as the delivery roller 20 rotates, the portion of the spreading members 320 located on the outer peripheral surface of the upper portion of the delivery roller 20 rotates to the lower portion of the delivery roller 20, and since the distance between the lower portions of the two rotary connectors 310 is smaller than the distance between the upper portions of the two rotary connectors 310, the spreading members 320 rotated to the outer peripheral surface of the lower portion of the delivery roller 20 slide toward the middle of the delivery roller 20 along the axial direction of the delivery roller 20, and since the spreading members 320 on the outer peripheral surface of the lower portion of the delivery roller 20 do not contact with the cloth, the cloth is not affected.
According to the above steps, the cloth can be spread by the spreading assembly 320 with the rotation of the delivery roller 20 and finally output through the delivery roller 40. When the cloth feeding direction deviates from the preset direction, that is, the cloth surface deviates along one side of the width direction of the cloth surface, the driving member 400 drives the limiting plate 210 to swing around the fixed end 211 thereof in the direction opposite to the deviating side, and since the rotary connecting member 310, the cloth spreading assembly 320 and the limiting plate 210 can swing simultaneously, the cloth on the surface of the cloth spreading assembly 320 can be moved to the other side opposite to the deviating direction, and thus the deviated cloth can be corrected to the correct direction.
The design structure is not complex, and the manufacturing cost is lower. Manual adjustment operation is not needed, the working efficiency is improved, and the spreading and flattening effects on the cloth are good; both sides of the cloth width direction can be always limited within the boundary, so that the cloth feeding direction is always kept consistent with the preset direction.
Because the surface of the cloth is smooth and tight during cloth feeding, the pattern with better quality can be printed after the cloth enters the printer subsequently. The cloth feeding direction is always consistent with the preset direction, and is always vertical to the width direction of the cloth, so that the cloth can be directly wound into a standard cloth roll after being fed out, and the cloth storage is facilitated; on the other hand, the cloth direction fed into the printer is very standard, and the situations of printing pattern deflection, quality substandard and the like can not occur.
