[0033] Working process:

[0034] First, according to the diameter of the TPU fixed ring 9, the second linear transmission device 5g and the longitudinal slider 5t adjust the shear head of the pneumatic scissors 5j to the appropriate height.

[0035] Then the cylinder output extends the burr positioning block 7c to the hole 7g, which is located in the notch a1, then the worker places the TPU fixed ring 9 on the placement plate 8, and inserts the sheet burr 9a of the TPU fixed ring 9 into the burr clamping groove 7d, and then clamps the TPU fixed ring 9 on both sides of the sheet burr 9a into the first clamping roller 4j and the second clamping roller 4k on both sides of the burr positioning block 7c, so that the TPU fixed ring 9 is clamped by the first clamping roller 4j and the second clamping roller 4k.

[0036] Then the second motor 4c starts, driving the screw rod 4b to rotate, so that the distance between the two nuts 4f on it increases by a certain distance, and at the same time the distance between the two sliders 4g also increases by a certain distance under the drive of the nuts 4f. At this time, the first clamping roller 4j and the second clamping roller 4k on the two sliders 4g will pull the TPU fixed ring 9 to both sides, so that the sheet burr of the TPU fixed ring 9 is tightened, ensuring that there is no wrinkle on the sheet burr, facilitating the trimming of the pneumatic scissors 5j and the quality inspection of the strength of the bonding part of the TPU fixed ring 9. At this time, the cylinder is retracted so that the burr positioning block 7c is retracted below the table top 2.

[0037] Finally, start the first motor 3u to drive the frame 3b to rotate downward so that the placement plate 8 is in a vertical state, then start the first linear transmission device 5c to push the second slider 5b forward, so that the blade of the pneumatic scissors 5j is in contact with the sheet burr 9a, then start the pneumatic scissors 5j to start cutting off the sheet burr 9a, and then start the first motor 3u again to drive the frame 3b to rotate in the opposite direction so that the pneumatic scissors 5j gradually cuts off all the sheet burrs 9a. After cutting, the whole device is reset.
