The output end of the motor is fixedly connected with a first rotating column. One side wall of the first rotating column is fixedly connected with a gear. However, when this device cuts the elastic band, after each cutting is completed, it is necessary to manually take out the elastic band, then fix the elastic band on the device again, and then perform the next cutting. The working efficiency of the device is low. At the same time, when this device cuts the elastic band, it is necessary to manually control the movement of the cutting knife to cut the elastic band, wasting labor force.

[0028] Refer to the attached Figure 5 and 7 -8:

[0029] The cutting structure 5 includes a hydraulic cylinder 501.

[0030] Working principle:

[0031] When it is necessary to cut the elastic band, the staff puts one end of the elastic band into the inside of the machine body 1 through the opening above the machine body 1 and makes it fit against the first round roller 405 and the second round roller 12.

[0032] Feeding work:

[0033] First, connect the external power supply of the first motor 401 to start the first motor 401 to drive the disc 402 to rotate. The rotation of the disc 402 drives the cylinder 403 to rotate. The rotation of the cylinder 403 can periodically drive the grooved wheel 404 to rotate. The rotation of the grooved wheel 404 drives the first roller 405 to rotate, so that the first roller 405 and the second roller 12 clamp the elastic band, and the elastic band is conveyed downward when the first roller 405 rotates.

[0034] When the elastic band falls to a certain position due to gravity, connect the external power supply of the electric telescopic rod 8 to start the electric telescopic rod 8 to drive the clamping plate 9 to move. The movement of the clamping plate 9 pushes the elastic band to abut against the first inclined plate 6 to fix the elastic band.

[0035] Cutting work:

[0036] Start the hydraulic cylinder 501 to drive the straight rod 502 to move. The movement of the straight rod 502 drives the connecting rod 503 to move to both sides. The movement of the connecting rod 503 to both sides drives the curved rod 505 to move to both sides. The movement of the curved rod 505 to both sides drives the front ends of the blades 506 to approach each other to cut the elastic band.

[0037] After cutting, the elastic band falls into the collection box 10 due to gravity. After cutting, the staff can pull the handle 11 to pull out the collection box from the inside of the machine body 1 to collect the cut elastic band.
