Description

Cloth feeder

Technical Field

The invention relates to the field of cloth processing equipment, in particular to a cloth feeder.

Background

In the cloth manufacturing process, it is necessary to feed the fabric to a printer via a cloth feeder and to perform surface pattern printing in the printer. In order to facilitate the relation between the cloth feeding speed of the cloth feeding 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 is required to be arranged between the cloth feeding machine and the printer. After the floating roller and the cloth feeding direction are vertically pressed on the cloth, the gravity of the floating roller is utilized to press the cloth, and when the cloth pulling speed of the printer is increased in the production process, a large pulling force is applied to the cloth so as to enable the floating roller to be increased, and the cloth feeding speed is required to be increased at the moment; when the cloth pulling speed is reduced, the pulling force on the cloth is reduced, so that the dancer roll is lowered, and at this time, the cloth feeding speed needs to be reduced. Therefore, the change of the cloth pulling speed of the printer and the relation between the cloth pulling speed of the printer and the cloth feeding speed of the cloth feeder are known by observing the rising and falling of the floating roller, so that a reference basis is provided for the adjustment of the cloth feeding speed. However, the change of the spreading speed of the spreading machine has a great randomness according to the requirements of the production process, and the weight of the floating roller is fixed, so that the highest point and the lowest point of the floating roller and the rising and falling stroke of the floating roller in different printing programs can be greatly changed, great trouble is brought to observation and monitoring, and the adjustment of the cloth feeding speed is also inconvenient.

Disclosure of Invention

Accordingly, it is necessary to provide a cloth feeder for solving the problem that the position change of the dancer roller is unstable during the cloth feeding and printing.

The utility model provides a cloth feeder, includes dancer roll and dancer roll stroke adjustment device, dancer roll stroke adjustment device includes:

the transmission chain assembly is connected with the floating roller so that the transmission chain assembly synchronously rotates under the drive of the floating roller;

the synchronous belt assembly is connected with the transmission chain assembly to be linked with the transmission chain assembly;

And the damping driving component is connected with the synchronous belt assembly to provide a damping force opposite to the moving direction of the synchronous belt assembly.

The cloth feeder has at least the following beneficial technical effects:

The highest point and the lowest point of the floating roller in the cloth feeding printing program and the stroke change from the rising to the falling of the floating roller are small, so that the position of the floating roller is greatly convenient to observe and monitor, and the cloth feeding speed and the cloth spreading speed are favorably adjusted to be matched.

The damping driving part does not directly drive the transmission chain assembly, so that the frequent application of force to the transmission chain assembly is prevented from generating larger stress and shortening the service life of the transmission chain assembly; the transmission chain component is linked with the synchronous belt component, and the damping driving component applies force to the synchronous belt component, so that the control and adjustment of a larger floating roller travel range are facilitated.

When the stroke of the floating roller is stabilized, the position of the middle point of the descending stroke is basically stabilized, and the whole cloth feeding speed level of the cloth feeder in the production process can be adjusted so that the middle point of the descending stroke of the floating roller reaches a proper position. For example, when the position of the middle point of the stroke 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 basis of the original cloth pulling speed; when the position of the middle point of the stroke is always lower, the cloth pulling speed is always at a relatively low level, and the cloth feeding speed level of the cloth feeder in the whole production process can be reduced on the basis of the original cloth pulling speed.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein 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 feeder 1 including a dancer roller stroke adjustment 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 synchronously rotates under the drive of the floating roller 10;

A timing belt assembly 120 coupled with the drive chain assembly 110 to be coupled with the drive chain assembly 110;

And a damping driving part 130 coupled with the timing belt assembly 120 to provide a damping force opposite to the moving direction of the timing belt assembly 120.

In the figure, a cloth is fed to the cloth feeder 1 via the cloth feed roller 30, is moved in a direction indicated by an arrow under the guidance of parallel guide rollers in the cloth feeder 1, and finally is fed forward via the feed-out roller 40 around the dancer roller 10 to the printer. In the working process, when the cloth pulling speed of the printer is increased, the pulling force of the cloth is increased to support the floating roller 10 to enable the position of the floating roller 10 to be increased, the rising floating roller 10 drives the transmission chain assembly 110 to rotate, the transmission chain assembly 110 rotates and simultaneously drives the synchronous belt assembly 120 to move, at the moment, the damping driving part 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 to be raised 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 pulling force on the cloth 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 reversely rotate, the transmission chain assembly 110 reversely rotates and simultaneously drives the synchronous belt assembly 120 to reversely move, and the damping driving part 130 provides damping force to slow the lowering speed of the floating roller 10 until the floating roller 10 stops descending, so that the height of the lowest point reached by the lowering of the floating roller is increased, and the lowering position is prevented from being excessively lowered.

Through implementing the process, the highest point and the lowest point of the floating roller 10 and the stroke change from the rising to the falling of the floating roller 10 in the printing program are small, so that the position of the floating roller 10 is greatly convenient to observe and monitor, and the cloth feeding speed is favorably adjusted to be matched with the cloth spreading speed.

The damping driving part 130 does not directly drive the transmission chain assembly 110, so that the frequent application of force to the transmission chain assembly 110 is prevented from generating larger stress to shorten the service life of the transmission chain assembly; 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 larger floating roller travel range can be controlled and adjusted.

In some embodiments, a drive train assembly 110 is provided at the end of dancer 10. Specifically, the transmission chain assembly 110 may be installed on the side of the cloth feeder 1, the side of the cloth feeder 1 is provided with a guide groove 1-1, and the end of the dancer 10 is disposed in the guide groove 1-1 and can move up and down along the guide groove 1-1. The installation operation is convenient by adopting the setting mode. In other embodiments, the drive train assembly 110 may be disposed in the middle of the dancer 10, without limitation.

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 dancer 10 is end-connected to the driving chain 112. The structure design is simple and easy, and the implementation and the installation are convenient. In other embodiments, the drive chain assembly 110 includes three or more sprockets and a drive chain 112 surrounding the sprockets, without limitation.

In some embodiments, the dancer 10 ends are connected to a drive chain 112 by a fixed block 11. The damage to the drive chain 112 caused by the direct connection can be avoided by the way of the connection of the fixing blocks 11.

In some embodiments, the guide posts 12 are disposed up and down, and slidably engage the fixed block 11 to slide the fixed block 11 along the length of the guide posts 12. The guide column 12 has a guide function, so that the fixed block 11 and the floating roller 10 can be ensured to translate up and down all the time, and the position deviation is avoided for a long service time.

With continued reference to fig. 5, in some embodiments, the synchronous belt assembly 120 includes two pulleys 121 and a belt body 122 encircling the two pulleys 121. The structure design is simple and easy, and the implementation and the installation are convenient. In other embodiments, the timing belt assembly 120 includes three or more pulleys 121 and a belt body 122 surrounding the pulleys 121, without limitation. Preferably, the band 122 is a flat band.

In some embodiments, two pulleys 121 are disposed coaxially with the two drive sprockets 111, respectively. In this embodiment, the two pulleys 121 are coaxially arranged with the two driving sprockets 111, so that the installation space of the whole device can be saved, and the installation length of the driving chain assembly 110 can be prolonged, which is beneficial to controlling and adjusting a larger travel range. In other embodiments, one of the two pulleys 121 is coaxially disposed with one of the two drive sprockets 111, and may be coupled to the drive chain assembly 110 for interlocking purposes, as not limited herein.

In some embodiments, the damping driving part 130 is a telescopic rod 131, an extending direction of the telescopic rod 131 is parallel to a moving direction of the timing belt assembly 120, and an 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 slow down the timing belt assembly 120 until the timing belt assembly 120 stops moving, thereby stopping the up-and-down movement of the dancer 10 synchronously. Preferably, the telescopic rod 131 is a cylinder. Specifically, the air cylinder may be controlled to be pressurized by a precise pressure regulating valve to generate a damping force, and the moving speed is reduced until the stop by applying resistance to the dancer 10 by the timing belt assembly 120, which corresponds to changing the weight of the dancer 10. In other embodiments, the telescopic rod 131 may be an electric telescopic rod 131 or a hydraulic cylinder, which generates a damping force by current change and hydraulic force application, respectively, without limitation.

In some embodiments, the ends of the telescoping rod 131 are slidably disposed on a guide rod 132 parallel to the telescoping rod 131. The guide rod 132 has a guiding function, so that the telescopic rod 131 can be ensured to stretch along the self extending direction all the time, and the use time is prevented from shifting the self stretching direction.

In some embodiments, the end of the telescoping 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 belt body 122. In the embodiment, the clamping mode can avoid directly connecting the clamping body 133 with the belt body 122 by using fasteners such as bolts, so that the damage to the surface of the belt can be reduced, and the service life is prolonged; and the clamping body 133 directly clamps the belt body 122, thereby preventing the belt body 122 from being deformed.

In some embodiments, further comprising:

A position detection unit for detecting the position of the dancer 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 increased, the cloth spreading speed of the cloth spreading machine is increased, and the control unit controls the cloth feeding speed of the cloth feeding machine 1 to be increased so as to be matched with the cloth spreading speed; when the sensor detects a decrease in the position of the dancer roll 10, indicating a decrease in the cloth pulling speed of the cloth puller at this time, the control unit controls the cloth feeding speed of the cloth feeder 1 to be adjusted down so as to match the cloth pulling speed. Therefore, the aim of assisting in adjusting the cloth feeding speed in real time is achieved by using the embodiment, compared with a method for manually adjusting the cloth feeding speed, the method does not need to take care of in real time, and is convenient to operate; more importantly, the safety accident caused by collision between the floating roller 10 and other parts on the cloth feeder 1 due to the fact that the speed of the cloth feeder 1 is not manually adjusted timely due to negligence is avoided.

Preferably, the position detecting unit is a displacement sensor, and is disposed on the driving chain assembly 110. Specifically, the displacement sensor may be an absolute value encoder, and may be disposed on the driving sprocket 111 of the driving chain assembly 110, and because the driving sprocket 111 is driven by the dancer roll 10 to rotate synchronously, when the displacement sensor detects a change in the rotational position of the driving sprocket 111, it indicates that the horizontal position of the dancer roll 10 changes, that is, by detecting a change in the rotational position of the driving sprocket 111, it may reflect a change in the horizontal position of the dancer roll 10.

Further, the control unit is communicatively coupled to the damping drive section 130. When the control unit judges that the horizontal position of the dancer 10 is changed too much, the control unit controls the damping force of the height-adjusting damping driving part 130 to stop moving the dancer 10 in the shortest time to prevent the position of the dancer 10 from rising too high or falling too low to collide with other parts on the cloth feeder 1 and thus cause a safety accident.

When actually feeding cloth, the surface of many cloth is uneven, wrinkles are easy to appear, and the subsequent printing is affected; in addition, the cloth sent out by the cloth feeder 1 is easy to deviate from the standard cloth feeding direction, so that the cloth is inconvenient to store on one hand, and the direction of the cloth fed into the printer by the cloth feeder 1 is also deviated, and the printed pattern is askew and the quality is not up to standard. To this end, referring to fig. 3, in some embodiments, the cloth feeder 1 further comprises:

The cloth feeder 50 is provided adjacent to the cloth feed roller 30 of the cloth feeder 1 in the cloth feeder 1, and the axis of the cloth feeder 50 is parallel to the axis of the cloth feed roller 30.

The cloth dispenser 50 rotatably dispenses cloth. The cloth feeder 50 is adjacent to the cloth feed roller 30 of the cloth feeder 1 and is arranged on the cloth feeder 1, and the axis of the cloth feeder 50 is parallel to the axis of the cloth feed roller 30, so that the direction in which the cloth is fed out of the cloth feeder 50 is completely perpendicular to the cloth feed roller 30, the direction in which the cloth is fed into the cloth feeder 1 can be kept stable, the probability of deviation in the cloth feeding direction of the printer via the cloth feeder 1 is reduced, and the cloth coming out of the cloth feeder 1 is not easy to wrinkle.

In the embodiment, the cloth feeding direction is consistent with the preset direction, the cloth feeding direction is perpendicular 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 cloth direction fed into the printer is kept stable, and the situation that the printed pattern is askew can not occur. Because the cloth coming out of the cloth feeder 1 is not easy to wrinkle, the pattern with better quality can be printed after the cloth enters the printer later.

In order to meet various actual use demands, a cloth placing frame 60 can be arranged beside the cloth feeder 1, the cloth quantity of the cloth placing frame 60 which can be wound is larger, and the requirement of mass cloth feeding and printing can be met. When the processed cloth is less, the cloth is directly put by adopting the cloth putting device 50.

During use of the cloth feeder 1, it was found that the cloth fed from the cloth feeder 1 was not smooth enough and that the cloth fed through the cloth feeder 1 still had a certain probability of deviating from the standard feeding direction. To this end, referring to fig. 1, in some embodiments, the cloth feeder 1 further comprises:

a feed-out roller 20 rotatably provided to the cloth feeder 1;

The limiting structure comprises two limiting plates 210 which are oppositely arranged at two ends of the feed-out roller 20, wherein each limiting plate 210 comprises a fixed end 211 and a movable end 212 which can swing around the fixed end 211 along the width direction of the feed-out machine 1, the fixed ends 211 of the two limiting plates 210 are equal in horizontal height, 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 larger than the distance 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 sleeved on the sending-out roller 20, and a spreading component 320 which is distributed on the circumferential surface of the sending-out roller 20 and can slide along the axial direction of the sending-out roller 20, wherein two ends of the spreading component 320 along the axial direction of the sending-out roller 20 are respectively connected with the rotary connecting piece 310 on the corresponding side;

the driving part 400 is connected with one of the two limiting plates 210 to drive the limiting plate 210 to swing around 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 inclined to the outside of the feeding machine 1 with the fixed ends 211 as hinge points, respectively, and since the rotary connecting members 310 are mounted on the limiting plates 210, the upper parts of the rotary connecting members 310 are also inclined to the outside of the feeding machine 1 together with the limiting plates 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. A cloth spreading assembly 320 for guiding the cloth into the cloth feeder 1 through the cloth feeding roller 30 and spreading the cloth on the surface of the cloth feeding roller 20 along the circumferential direction, and driving the cloth feeding roller 20 to rotate so as to convey the cloth forward, wherein the cloth spreading assembly 320 is respectively connected with the rotary connecting pieces 310 on the corresponding sides along the two ends of the axial direction of the cloth feeding roller 20, when the cloth feeding roller 20 rotates, the part of the cloth spreading assembly 320 positioned on the upper peripheral surface 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 along the width direction by friction force generated by contact with the surface of the cloth; since the cloth spread assembly 320 is rotatable together with the feed-out roller 20, as the feed-out roller 20 rotates, a portion of the cloth spread assembly 320 located at the upper outer circumferential surface of the feed-out roller 20 rotates to the lower portion of the feed-out 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 cloth spread assembly 320 rotated to the lower outer circumferential surface of the feed-out roller 20 slides toward the middle of the feed-out roller 20 in the axial direction of the feed-out roller 20, and since the cloth spread assembly 320 at the lower outer circumferential surface of the feed-out roller 20 does not contact with cloth, it does not have an influence on cloth.

According to the above steps, the cloth is spread by the spread assembly 320 as the feed roller 20 rotates and finally fed out through the feed roller 40. When the cloth feeding direction deviates from the preset direction, i.e., one side of the cloth cover along the width direction thereof, the driving part 400 drives the limiting plate 210 to swing around the fixed end 211 thereof in the opposite direction to the deviation side, and the rotary connecting member 310, the cloth spreading assembly 320 and the limiting plate 210 can swing at the same time, so that the cloth on the surface of the cloth spreading assembly 320 can be moved to the other side opposite to the deviation direction, thereby correcting the deviated cloth to the correct direction.

The design structure is not complex, and the manufacturing cost is low. The manual adjustment operation is not needed, the working efficiency is improved, and the spreading and leveling effects on the cloth are good; both sides of the cloth width direction can be always limited in the boundary, so that the cloth feeding direction always keeps consistent with the preset direction.

Because the surface of the cloth is flat and tight when the cloth is fed, the pattern with better quality can be printed after the pattern subsequently enters the printer. The cloth feeding direction is always consistent with the preset direction, and is always perpendicular 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 is convenient to store; on the other hand, the direction of cloth fed into the printer is very standard, and the conditions that printed patterns are askew, the quality is not up to standard and the like can not occur.

In some embodiments, the two movable ends 212 are connected by a connecting rod 220 that is parallel to the feed-out roller 20. The device is simple in arrangement form, convenient to operate and easy to implement. In other embodiments, a fixed connection may be provided by a connector, without limitation.

Preferably, the length of the connecting rod 220 is adjustable. After the length of the connection rod 220 is changed, the outward inclination of the limiting plate 210 may be changed, for example, when the length of the connection rod 220 is increased, the outward inclination of the limiting plate 210 is greater, and during the rotation of the delivery roll 20, the cloth spreading assembly 320 rotated to the upper peripheral surface of the delivery roll 20 may slide a longer distance toward both ends of the delivery roll 20 in the axial direction of the delivery roll 20, thereby increasing the acting time on the cloth by extending the sliding amount, spreading the cloth more fully along the width thereof, and spreading the cloth spread on the surface of the cloth spreading assembly 320 more effectively to remove wrinkles.

Preferably, the connecting rod 220 includes two rod bodies 221 and a screw sleeve 222 disposed between the two rod bodies 221 for butting threaded ends of the rod bodies 221. In operation, the connecting rod 220 can be lengthened or shortened by rotating the threaded sleeve 222, the operation is simple and convenient, and the setting cost is low. In other embodiments, the connecting rod 220 may be an electric telescopic rod 131 or a pneumatic rod, without limitation.

Referring to fig. 1,3 and 4, in some embodiments, the spreading assembly 320 includes a plurality of sliding bodies 321 respectively distributed on circumferential surfaces of both ends of the feed-out roller 20, the sliding bodies 321 may slide along an axial direction of the feed-out roller 20, and ends of the sliding bodies 321 are connected with the swing connectors 310 of the corresponding sides. In the embodiment shown in the drawing, the two limiting plates 210 are respectively inclined to the outside of the cloth feeder 1 by taking the fixed ends 211 as hinge points, and since the rotary connecting members 310 are mounted on the limiting plates 210, the upper parts of the rotary connecting members 310 are also inclined to the outside of the cloth feeder 1 together with the limiting plates 210, i.e. 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. Since the end of the sliding body 321 is connected to the rotary connector 310 on the corresponding side, the sliding body 321 moving to the upper outer circumferential surface of the feed-out roller 20 when the feed-out roller 20 rotates slides toward the end of the feed-out roller 20 in the axial direction of the feed-out roller 20, and the cloth laid on the surface thereof is spread in the width direction by the frictional force generated by contact with the cloth surface to remove wrinkles; with the rotation of the feed-out roller 20, the sliding body 321 of the upper outer circumferential surface of the feed-out roller 20 rotates to the lower portion of the feed-out roller 20, and since the distance between the lower portions of the two swing links 310 is smaller than the distance between the upper portions of the two swing links 310, the sliding body 321 slides toward the middle portion of the feed-out roller 20 in the axial direction of the feed-out roller 20 when rotating to the lower portion of the feed-out roller 20, and since the sliding body 321 does not contact with the cloth when rotating to the lower outer circumferential surface of the feed-out roller 20, it does not affect the cloth.
