[0034] It should be noted that: The primary power source preferably selects a biaxial motor 21, and the two shafts are respectively fixedly connected with transmission rods 22;

[0035] It should be added that: One ends of the two groups of worms 231 are respectively fixedly connected to one ends of the corresponding transmission rods 22, and each group of worms 231 meshes with the corresponding worm gear 232.

[0036] Furthermore, a rectangular wrapping box is provided around the worm 231 and the worm wheel 232. The worm 231 and the worm wheel 232 are rotatably arranged in the rectangular wrapping box. At the same time, the transmission rod 22 passes through the rectangular wrapping box and can support the rectangular wrapping box.

[0037] A number of groups of feed ports 11 are provided on the equipment main body 1 to facilitate the entry of the PVC rubber strip. A discharge port 12 is provided at the bottom of the equipment main body 1 to facilitate the discharge of the granular PVC rubber strip after cutting. A motor hole 13 is provided on the right side of the equipment main body 1. A bearing 14 is fixedly connected to the inner wall of the equipment main body 1. A bearing ring guide groove 15 is provided on one side of the upper part of the equipment main body 1. The motor fixed disk bearing ring 26 is movably arranged in the bearing ring guide groove 15.

[0038] The cutting assembly 3 includes a secondary power source. One end of the secondary power source is connected to a lower roller 34. The lower roller 34 is rotatably arranged on the equipment main body 1 to keep its position fixed. The cutting assembly 3 further includes a tertiary power source. One end of the tertiary power source is connected to an upper roller 33. The upper roller 33 is connected to the motor fixed disk 25.

[0039] It should be noted that: the secondary power source is preferably the first driving motor 31, and the tertiary power source is preferably the second driving motor 32. The first driving motor 31 is fixedly connected to the outside of the equipment main body 1, and the second driving motor 32 is fixed on the motor fixed disk 25.

[0040] It should be added that: the first driving motor 31 and the second driving motor 32 rotate in opposite directions during operation.

[0041] The output shaft of the secondary power source passes through the motor hole 13 on the equipment main body 1 and is fixedly connected to one end of the lower roller 34 for driving the lower roller 34 to rotate.

[0042] A number of cutter teeth are provided on the surfaces of the lower roller 34 and the upper roller 33, and the material is stainless steel. Through the arrangement of the cutter teeth on the lower roller 34 and the upper roller 33, the cutting of the PVC rubber strip can be realized. And because the cutter teeth are densely distributed on the surfaces of the lower roller 34 and the upper roller 33, the PVC rubber strip can be cut into granules during the cutting process of the PVC rubber strip.

[0043] The specific principle is as follows: According to the size of the target PVC pellets, the biaxial motor 21 is started to drive the rotating rod 22 to rotate. The rotating rod 22 drives the worm 231 in the transmission assembly 23 to rotate, which drives the worm gear 232 to rotate. At the same time, the worm gear 232 drives the lead screw 24 to rotate, and the lead screw 24 drives the motor fixed disk bearing ring 26 and the motor fixed disk 25 to move up and down in the bearing ring guide groove 15. The second drive motor 32 and the upper roller 33 are driven by the motor fixed disk 25 to move up and down in the bearing ring guide groove 15, so that the distance between the lower roller 34 and the upper roller 33 can be changed to meet the cutting requirements of PVC pellets with different diameters, and the purpose of changing the size of the cut pellets can be achieved. Then, the strip-shaped PVC strip enters between the two rollers through the feed port 11. At the same time, the second drive motor 32 and the first drive motor 31 fixed on the output shaft on one side of the equipment main body 1 passing through the motor hole 13 are started. Then, the strip-shaped plastic is cut into pellets. After that, the cut PVC pellets will be discharged through the discharge port 12.
