Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] Please refer to Figures 1-8 A cloth pulling machine for garment production, comprising a mounting rack 1 and sequentially arranged cloth feeding assembly 2, guiding assembly 3, positioning and cutting assembly 4 and cloth pulling assembly 5 assembled on the mounting rack 1.

[0042] The feeding assembly 2 comprises a cloth storage roller 21 and a driving mechanism 22, the cloth storage roller 21 is rotatably installed on the mounting rack 1, the cloth 7 is wound on the cloth storage roller 21 and sequentially passes through the guide assembly 3, the positioning and cutting assembly 4 and is fixed by the cloth pulling assembly 5, the driving mechanism 22 is assembled on the mounting rack 1 and is power-connected with the cloth storage roller 21.

[0043] The cloth pulling assembly 5 comprises a sliding rack plate 51, an extension rack plate 52 and upper and lower clamping plates 531 and 532 respectively clamping the upper and lower sides of the cloth 7, the sliding rack plate 51 is assembled on the mounting rack 1 and slides along the length direction of the cloth 7, the extension rack plate 52 is fixedly connected with an extension shaft 521 which is slidingly installed on the sliding rack plate 51, the upper and lower clamping plates 531 and 532 are both hingedly connected with connecting rods A 533 and B 534, the connecting rods A 533 and B 534 are respectively hingedly connected with the sliding rack plate 51 and the extension shaft 521.

[0044] Further comprising a cloth discharging assembly 6 assembled in the mounting rack 1, the cloth discharging assembly 6 is arranged below the feeding assembly 2, the guide assembly 3, the positioning and cutting assembly 4 and the cloth pulling assembly 5.

[0045] The mounting rack 1 can ensure that the feeding assembly 2, the guide assembly 3, the positioning and cutting assembly 4, the cloth pulling assembly 5 and the cloth discharging assembly 6 are stably assembled and operated thereon, so as to realize the pulling, cutting and discharging of the cloth 7.

[0046] When the cloth pulling operation is performed, the cloth 7 wound on the cloth storage roller 21 is discharged under the driving of the driving mechanism 22, and the cloth 7 is pulled straight under the driving of the cloth pulling assembly 5, the discharging speed of the cloth storage roller 21 is matched with the running speed of the sliding rack plate 51 in the cloth pulling assembly 5, so that the discharged cloth 7 is maintained within a specific tension level range, the pulling operation is realized, after the cloth 7 is pulled out to a specific length, the positioning and cutting assembly 4 operates to cut the cloth 7, at this time, the cloth pulling assembly 5 cancels the clamping posture of the cut cloth 7, so that the cloth 7 falls into the cloth discharging assembly 6 below and is outputted outward by the cloth discharging assembly 6.

[0047] The guide assembly 3 can stably transition the cloth 7 discharged from the cloth storage roller 21 and be received by the cloth pulling assembly 5, and can also flatten the width direction of the cloth 7, so as to avoid the folding of the cloth 7 in the pulling process.

[0048] For the cloth pulling assembly 5, when the extension rack plate 52 drives the extension shaft 521 to move towards one side of the upper and lower clamping plates 531 and 532, the upper and lower clamping plates 531 and 532 can be separated from each other and cancel the clamping action on the cloth 7 through the action of the connecting rods A 533 and B 534, when the extension rack plate 52 reversely moves, the upper and lower clamping plates 531 and 532 can be brought close to each other and clamp the cloth 7.

[0049] To ensure that the discharging assembly 2 can be stably assembled on the mounting rack 1, and to facilitate the disassembly and assembly of the cloth storage roller 21, and to realize the stable discharge of the cloth 7, the following technical solutions are provided.

[0050] A U-shaped clamping groove 11 is formed on the mounting rack 1, and a connecting shaft 211 is fixedly connected to the axis of the cloth storage roller 21 and rotatably installed in the U-shaped clamping groove 11.

[0051] The driving mechanism 22 includes a driving motor A221, a spline shaft 222, a telescopic cylinder A223, and a worm gear 224 and a worm shaft 225 rotatably installed on the outside of the mounting rack 1. The output shaft of the driving motor A221 is power-connected with the worm shaft 225, the worm shaft 225 is in meshing engagement with the worm gear 224, coaxial splines are formed at the axis of the worm gear 224 and the connecting shaft 211, the telescopic cylinder A223 is fixedly installed on the outside of the mounting rack 1, and the spline shaft 222 is slidingly inserted into the spline and rotatably connected with the movable end of the telescopic cylinder A223.

[0052] A bearing 212 can be assembled on the connecting shaft 211, which is in close contact with the U-shaped clamping groove 11, and can ensure the stability of the operation of the cloth storage roller 21 in the U-shaped clamping groove 11. At the same time, the U-shaped clamping groove 11 facilitates the disassembly and assembly of the cloth storage roller 21.

[0053] When the driving motor A221 is working, it can drive the worm shaft 225 to rotate, and in turn drive the worm gear 224 and the spline shaft 222 inserted therein to stably rotate. When the spline shaft 222 is inserted into the spline of the connecting shaft 211 by the telescopic cylinder A223, the power at the end of the worm gear 224 can be transmitted to the connecting shaft 211 through the spline shaft 222, and in turn drive the cloth storage roller 21 to stably rotate.

[0054] When it is necessary to replace the cloth storage roller 21, the telescopic cylinder A223 is controlled to drive the spline shaft 222 to extend out of the spline on the connecting shaft 211, so as to cut off the power connection between the driving mechanism 22 and the cloth storage roller 21, and in turn facilitate the replacement of the cloth storage roller 21.

[0055] Since the worm gear 224 and the worm shaft 225 have the characteristics of speed reduction and torque increase and one-way self-locking, when the power is transmitted from the worm shaft 225 to the worm gear 224, the torque can be amplified and the speed can be reduced, so as to drive the cloth storage roller 21 to rotate stably at low speed. The power can only be transmitted from the worm shaft 225 to the worm gear 224 in one direction, which can also avoid the invalid rotation of the cloth storage roller 21 caused by the cloth storage assembly 5 pulling the cloth storage roller 21 through the discharged cloth 7, and in turn cause the problem of insufficient pulling force applied to the cloth 7.

[0056] To ensure that the guiding assembly 3 can be stably installed and operated on the mounting rack 1, and to realize the transition and transition of the discharged cloth 7 and the flattening of the cloth 7 in the width direction, the following technical solutions are provided.

[0057] The guiding assembly 3 comprises two groups of guiding rollers 31 and an action roller 32 arranged between the two groups of guiding rollers 31, the guiding rollers 31 and the action roller 32 are rotatably installed on the mounting rack 1, the cloth 7 sequentially passes along the arrangement direction of the guiding rollers 31 and the action roller 32, the outer surface of the action roller 32 is fixedly connected with two groups of spiral strips 321 arranged in opposite spiral directions, the two groups of spiral strips 321 are connected at the center of the action roller 32, and the upper surface of the cloth 7 is in close contact with the spiral strips 321.

[0058] When the cloth 7 is transmitted under the joint action of the feeding assembly 2 and the cloth pulling assembly 5, the guiding rollers 31 and the action roller 32 can be stably operated, the guiding rollers 31 can stably transition the cloth 7 discharged from the cloth storage roller 21 to the cloth pulling assembly 5, so that the discharged cloth 7 is arranged horizontally under the action of the cloth pulling assembly 5.

[0059] The action roller 32 and the spiral strips 321 arranged thereon can exert a parallel and width direction force on the cloth 7 during operation, thereby effectively flattening the cloth 7 passing through the action roller 32 in the width direction.

[0060] In order to ensure that the positioning and cutting assembly 4 can be stably installed on the mounting rack 1 and realize positioning and cutting of the straightened cloth 7, the following technical solutions are provided.

[0061] The mounting rack 1 is fixedly connected with a mounting rack plate 12 arranged along the width direction of the cloth 7, the positioning and cutting assembly 4 comprises a pad 41, a pressing seat 42, a cutting knife 43, and a telescopic cylinder B 44 and a telescopic cylinder C 45 fixedly installed on the mounting rack plate 12 and arranged in a vertical direction, the pad 41 is arranged below the cloth 7, the pressing seat 42 and the cutting knife 43 are arranged above the cloth 7 and are fixedly connected with the movable ends of the telescopic cylinder B 44 and the telescopic cylinder C 45 respectively.

[0062] When cutting the cloth 7, first control the telescopic cylinder B 44 to drive the pressing seat 42 to move downward, so that the pressing seat 42 cooperates with the pad 41 and clamps and positions the cloth 7, then control the telescopic cylinder C 45 to drive the cutting knife 43 to move downward and cooperate with the pad 41 to complete the cutting of the cloth 7.

[0063] The cutting knife 43 is arranged at the rear side of the pressing seat 42, after the cloth 7 is cut, the cloth 7 discharged from the cloth storage roller 21 is still clamped between the pad 41 and the pressing seat 42, which facilitates the cloth pulling assembly 5 transporting from here to clamp and cut the cloth 7 again.

[0064] In order to ensure that the sliding rack plate 51 in the cloth pulling assembly 5 can stably slide on the mounting rack 1 and ensure that the telescopic rack plate 52 can stably slide relative to the sliding rack plate 51, the following technical solutions are provided.

[0065] The sliding guide groove 13 is arranged on the mounting rack 1, and the sliding rack plate 51 is slidingly installed in the sliding guide groove 13.

[0066] The cloth pulling assembly 5 further comprises a driving motor B54, adjusting lead screws 55 and a telescopic cylinder D56. The adjusting lead screws 55 are rotatably installed on the two sides of the mounting rack 1. The two ends of the sliding rack plate 51 are fixedly connected with connecting seats 511 which are rotatably connected with the adjusting lead screws 55. The ends of the two adjusting lead screws 55 are fixedly connected with transmission sprockets A551. The two transmission sprockets A551 are connected through a chain transmission. The output shaft of the driving motor B54 is power-connected with one of the adjusting lead screws 55. The telescopic cylinder D56 is fixedly installed on the sliding rack plate 51, and the movable end of the telescopic cylinder D56 is fixedly connected with the telescopic rack plate 52.

[0067] The arrangement of the sliding guide groove 13 can ensure the stable sliding of the sliding rack plate 51 along the horizontal direction. When one of the adjusting lead screws 55 is driven to rotate by the driving motor B54, the two adjusting lead screws 55 can be simultaneously driven to rotate through the combination of the transmission sprocket A551 and the chain, and then the sliding rack plate 51 can be stably slid along the sliding guide groove 13 through the combination of the adjusting lead screw 55 and the connecting seat 511.

[0068] During the telescopic movement of the telescopic cylinder D56, the telescopic rack plate 52 can be driven to telescopically move relative to the sliding rack plate 51, so as to adjust the clamping and loosening posture of the upper clamping plate 531 and the lower clamping plate 532.

[0069] In order to ensure that the cloth discharging assembly 6 can be stably installed on the mounting rack 1 and effectively transmit the cloth which cannot be cut, the following technical solutions are provided.

[0070] The cloth discharging assembly 6 comprises driving motor C61 and transmission rollers 62 and a receiving plate 63 which are arranged in pairs. The transmission rollers 62 are rotatably installed on the mounting rack 1. The receiving plate 63 is fixedly installed on the mounting rack 1 and is flush with the top of the transmission rollers 62. The transmission rollers 62 are fixedly connected with transmission sprockets B621. The transmission sprockets B621 on the two groups of transmission rollers 62 are connected through a chain transmission. The driving motor C61 is power-connected with one of the transmission rollers 62.

[0071] After the cloth 7 is cut by the positioning and cutting assembly 4, the cut end can fall on the cloth discharging assembly 6 below. The uniformly arranged transmission rollers 62 and the receiving plate 63 can effectively receive the cloth 7 and avoid the cloth 7 from falling through the gap between the transmission rollers 62. Then the cloth pulling assembly 5 releases the cut cloth 7, so that the cloth 7 completely falls on the cloth discharging assembly 6. The combination of the transmission sprockets B621 and the chain can ensure that the transmission rollers 62 always rotate synchronously. When the transmission rollers 62 are driven to rotate by the driving motor C61, the cloth 7 on the transmission rollers 62 can be output from the discharging assembly 2.

[0072] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the application can be implemented in other particular forms without departing from the spirit or essential characteristics of the application. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
