like Fig. 9 and Fig.10 and Fig.11 and Fig.15 The cutting member includes a U-shaped horizontal plate 6 arranged at the top of the two vertical plates 21, and a slider 61 is horizontally slidably connected to the horizontal edge of the inner side of the horizontal plate 6, and a cutting knife 611 is inclined on the slider 61 for cutting the cloth, and the cutting knife 611 is located below the first rotating shaft 51 and the second rotating shaft 52, and one end of the cutting knife 611 away from the slider 61 is located outside the horizontal plate 6, and a second screw rod 62 is rotatably connected between the opposite sides of the horizontal plate 6, and one end of the second screw rod 62 passes through the slider 61 and is threadedly connected to the slider 61, and a third motor 63 for driving the second screw rod 62 to rotate is provided on the horizontal plate 6.

[0031] like Figure 8 and Fig. 9 and Fig.10 and Fig.11 and Fig.12 and Fig.13 and Fig.14 and Fig.15 , when the dynamic code template is away from the fixed code template, and the fabric needs to be hung on the hanging needle 811: In the first step, the servo motor 114 is turned on. The rotating shaft of the servo motor 114 drives the gear 115 to rotate. The gear 115 drives the installation shaft 11 to rotate through the gear ring 112 meshing therewith. At this time, the suspension plate 117, the suspension 4 and the slide plate 2 will follow the installation shaft 11 and rotate along the rotation axis of the installation shaft 11 until the installation shaft 11 rotates 90 degrees, so that the suspension 4 is transferred from between the two corresponding guide rods above and below to between the dynamic code template and the fixed code template (such as Figure 1 ), at this time, the connecting grooves 214 on the first clamping plate 211 and the second clamping plate 212 will correspond to the hanging pins 811 on the cavity plate in the dynamic code template.

[0032] In the second step, the two second motors 53 are turned on. The rotating shafts of the two second motors 53 drive the first rotating shaft 51 and the second rotating shaft 52 to rotate synchronously respectively. The first rotating shaft 51 and the second rotating shaft 52 rotate in opposite directions. At this time, through the cooperation of the rotating first rotating shaft 51 and the second rotating shaft 52 and the first sleeve 511 and the second sleeve 521, the cloth on the two cloth rolls 218 can be released between the first clamping plate 211 and the second clamping plate 212, and the cloth released from the two cloth rolls 218 overlap.

[0033] In the third step, after the cloth is released between the first clamping plate 211 and the second clamping plate 212, the two second motors 53 stop working. At this time, the overlapping part of the two cloths is located between the contact plate 315 and the second clamping plate 212, and then the first clamping plate 211 is pushed close to the second clamping plate 212 by the piston rod of the first cylinder 213. At this time, the sliding column 312, the connecting plate 313, the tension spring 314 and the contact plate 315 will move with the first clamping plate 211 until the contact plate 315 presses the overlapping part of the two cloths against the second clamping plate 212.

[0034] The fourth step is to open the second cylinder 221. The piston rod of the second cylinder 221 drives the two pushing plates 222 away from the fixed plate 22 until the two pushing plates 222 pass through the two vertical grooves 215 on the first clamping plate 211 and the second clamping plate. At this time, the pushing plates 222 will make the cloth between the first clamping plate 211 and the second clamping plate 212 protrude from the vertical groove 215 on the second clamping plate 212, and then the piston rod of the first cylinder 213 pushes the first clamping plate 211 to approach the second clamping plate 212 again. At this time, the contact plate 315 will enter the placement groove 3, and the tension spring 314 will be pulled until the first clamping plate 211 presses the cloth tightly on the second clamping plate.

[0035] The fifth step is to use the oil cylinder to make the moving code template close to the fixed code template. At this time, the moving code template will be close to the second clamping plate 212 until one end of the hanging needle 811 on the cavity plate in the moving code template passes through the connecting groove 214 on the first clamping plate 211 and the second clamping plate 212. At this time, the hanging needle 811 will pierce the cloth, and the cloth protruding from the vertical groove 215 on the second clamping plate 212 will enter the cavity on the cavity plate.

[0036] The sixth step is to transport the cloth under the first rotating shaft 51 and the second rotating shaft 52 upward by cooperating with the first sleeve 511 and the second sleeve 521 through the rotating first rotating shaft 51 and the second rotating shaft 52, tighten the cloth, and then turn on the third motor 63. The rotating shaft of the third motor 63 drives the second screw rod 62 to rotate. At this time, because one end of the second screw rod 62 passes through the slider 61 and is threadedly connected with the slider 61, when the second screw rod 62 rotates, it can drive the slider 61 to move horizontally on the cross plate 6. When the slider 61 moves horizontally, the slider 61 passes through one side of the cloth. At this time, the cutting knife 611 on the slider 61 can cut the cloth tightened under the first rotating shaft 51 and the second rotating shaft 52. After the cloth under the first rotating shaft 51 and the second rotating shaft 52 is cut, the rotating shaft of the third motor 63 drives the second screw rod 62 to rotate in the opposite direction, so that the slider 61 moves back to its original position.

[0037] In the seventh step, the piston rod of the second cylinder 221 drives the two pushing plates 222 to approach the fixed plate 22 until the two pushing plates 222 move to the side of the first clamping plate 211 away from the second clamping plate 212, and the first cylinder 213 makes the first clamping plate 211 move away from the second clamping plate 212 to release the clamping of the cloth.

[0038] The eighth step is to turn on the first motor 413. The rotating shaft of the first motor 413 drives the first screw rod 412 to rotate clockwise. At this time, because one end of the first screw rod 412 passes through the push block 411 and is threadedly connected to the push block 411, and the push block 411 is on the slide plate 2, when the first screw rod 412 rotates clockwise, the slide plate 2 can be driven to move vertically upward in the suspension 4 through the push block 411. At this time, the vertical plate 21 and the first clamping plate 211 and the second clamping plate 212 will move upward with the slide plate 2. At this time, as the first clamping plate 211 and the second clamping plate 212 move upward, the hanging needle 811 will move downward in the connecting groove 214, and the cloth on the hanging needle 811 located between the first clamping plate 211 and the second clamping plate 212 will also move downward until each hanging needle 811 moves vertically downward from the connecting groove 214.

[0039] In the ninth step, after the hanging needle 811 moves vertically downward from the connecting groove 214, the oil cylinder is used to make the movable code template move away from the second clamping plate 212, and then the rotating shaft of the first motor 413 drives the first screw rod 412 to rotate counterclockwise, so that the slide plate 2 and the vertical plate 21 and the first clamping plate 211 and the second clamping plate 212 move downward back to their original positions, and then the rotating shaft of the servo motor 114 drives the gear 115 to rotate 90 degrees in the opposite direction, so that the suspension 4 can be rotated out from between the two corresponding guide rods above and below and between the movable code template and the fixed code template. Through the above process, there is no need to manually hang the cloth on the hanging needle 811, which saves manpower.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
