[0065] As Figure 8 and Figure 9 and Figure 10 and Figure 11 and Figure 12 and Figure 13 and Figure 14 and Figure 15 When the moving die template is far away from the fixed die template, and then the cloth needs to be hung on the hanging needle 811:

[0066] Firstly, 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 mounting shaft 11 to rotate through the tooth ring 112 engaged with the gear 115, at this time, the suspension plate 117 and the suspension 4 and the sliding plate 2 will rotate along the rotating axis of the mounting shaft 11, until the mounting shaft 11 rotates by 90 degrees, so that the suspension 4 is turned into the moving die template and the fixed die template from between the two guide rods corresponding to the upper and lower (such as Figure 1 ), at this time, the communication groove 214 on the first clamping plate 211 and the second clamping plate 212 will be corresponding to the hanging needle 811 on the cavity plate of the moving die template.

[0067] Secondly, 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, the rotating directions of the first rotating shaft 51 and the second rotating shaft 52 are opposite, at this time, through the cooperation of the first sleeve 511 and the second sleeve 521 with the rotating first rotating shaft 51 and the second rotating shaft 52, the cloth on the two cloth rolls 218 can be put out to the first clamping plate 211 and the second clamping plate 212, and the cloth put out from the two cloth rolls 218 can be overlapped.

[0068] Third step, after the cloth is put out 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 abutting plate 315 and the second clamping plate 212, then the piston rod of the first cylinder 213 pushes the first clamping plate 211 to move close to the second clamping plate 212, at this time the slide column 312, the connecting plate 313, the tension spring 314 and the abutting plate 315 will move with the first clamping plate 211, until the abutting plate 315 tightly abuts the overlapping part of the two cloths on the second clamping plate 212.

[0069] Fourth step, open the second cylinder 221, the piston rod of the second cylinder 221 drives the two push plates 222 to move away from the fixed plate 22, until the two push plates 222 pass through the two vertical grooves 215 on the first clamping plate 211 and the second clamping plate, at this time the push plate 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, then the piston rod of the first cylinder 213 pushes the first clamping plate 211 to move close to the second clamping plate 212 again, at this time the abutting plate 315 will enter the placing groove 3, the tension spring 314 is pulled by the pull rope, until the first clamping plate 211 tightly presses the cloth on the second clamping plate.

[0070] Fifth step, through the oil cylinder, the movable die template moves close to the fixed die template, at this time the movable die template moves close to the second clamping plate 212, until one end of the hanging needle 811 on the cavity plate in the movable die template passes through the communication 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.

[0071] Sixth step, 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 below the first rotating shaft 51 and the second rotating shaft 52 is conveyed upward, the cloth is tightened, then the third motor 63 is opened, 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 sliding block 61 and is threadedly connected with the sliding block 61, so when the second screw rod 62 rotates, it can drive the sliding block 61 to move horizontally on the horizontal plate 6, when the sliding block 61 moves horizontally, the sliding block 61 passes through one side of the cloth, at this time the cutting knife 611 on the sliding block 61 can cut the cloth tightened below the first rotating shaft 51 and the second rotating shaft 52, after the cloth below 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 reversely, so that the sliding block 61 moves back to the original position.

[0072] Seventh step, through the piston rod of the second cylinder 221 drive two push plate 222 close to the fixed plate 22, until two push plate 222 are moved to the first clamping plate 211 away from the second clamping plate 212 one side, and through the first cylinder 213 make the first clamping plate 211 away from the second clamping plate 212, release the clamping of cloth.

[0073] Eighth step, open the first motor 413, the rotating shaft of the first motor 413 drive the first screw 412 clockwise, at this time because the first screw 412 one end through the push block 411 and with push block 411 screw connection, and push block 411 along with in the slide plate 2, so when the first screw 412 clockwise rotation can be through the push block 411 drive the slide plate 2 in the suspension 4 vertical upward movement, at this time the vertical plate 21 and the first clamping plate 211 and the second clamping plate 212 will follow the slide plate 2 upward movement, at this time along with the first clamping plate 211 and the second clamping plate 212 upward movement, the needle 811 will be in the communication groove 214 downward movement, and the cloth on the needle 811 between the first clamping plate 211 and the second clamping plate 212 will also move downward, until each needle 811 is from the communication groove 214 vertical downward move out.

[0074] Ninth step, when the needle 811 from the communication groove 214 vertical downward move out, through the oil cylinder, make the dynamic code template away from the second clamping plate 212, then the rotating shaft of the first motor 413 drive the first screw 412 counterclockwise rotation, make the slide plate 2 and the vertical plate 21 and the first clamping plate 211 and the second clamping plate 212 move back to the original position, then the rotating shaft of the servo motor 114 drive gear 115 reverse rotation 90 degrees, make the suspension 4 from the corresponding two guide rod between the dynamic code template and the fixed code template can be out, through the above process, without manual cloth hanging on the needle 811, save manpower.

[0075] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the application. Thus, if these modifications and variations of the application fall within the scope of the application claims and their equivalent technology, the application also intends to include these modifications and variations.
