For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0028] like Figure 1 , Figure 2 , Figure 3As shown, a plastic particle segmentation device includes a bottom plate 1, a top plate 2 and a slitting mechanism 3. A leg 11 is provided at the bottom corner of the bottom plate 1, a limiting rod 12 is provided at the top corner, a limiting hole 23 is provided at the corner of the top plate 2, a through hole is provided on the side wall of the limiting hole 23, a bolt is threadedly provided at the through hole, the limiting rod 12 is provided through the limiting hole 23, and the end of the bolt is provided to press the limiting rod 12, thereby making the bottom plate 1 and the top plate 2 stably connected, and at the same time providing support for adjusting the relative position of the top plate 2 and the bottom plate 1 according to the slitting requirements of the plastic long strip raw material. The slitting mechanism 3 is provided at the front side of the top plate 2 and the bottom plate 1, and includes a slitting knife 34 and a control device, and the control device can force the slitting knife 34 to regularly rise and fall in contact with the front side of the top plate 2, thereby slitting the plastic long strip raw material protruding from the bottom plate 1 and the top plate 2.

[0029] like Figure 2 , Figure 3 As shown, in order to make the plastic long strip material stable during the cutting process, limiting grooves 13 are arranged on the adjacent side walls of the bottom plate 1 and the top plate 2. The limiting grooves 13 are arranged along the width direction of the bottom plate 1 and the top plate 2, and there are multiple limiting grooves 13. Both ends of each limiting groove 13 are arranged to be openings. Therefore, when cutting the plastic long strip material, it is penetrated through the space formed by the two limiting grooves 13 set on the top plate 2 and the bottom plate 1. Under the action of the limiting grooves 13, the plastic long strip material is forced to be stable and movably set at the limiting grooves 13. At the same time, the plastic long strip material is cut while the slitting knife 34 moves up and down, thereby realizing the limitation of the position of the plastic long strip material, avoiding the deviation of the plastic long strip material due to the action of the slitting knife, affecting the slitting of plastic particles.

[0030] like Figure 2 , Figure 3 , Figure 4 As shown, in order to control the long plastic strip material to intermittently protrude from the top plate 2 and the bottom plate 1, a first mounting hole 15 is provided on the bottom plate 1, and a second mounting hole 22 is provided on the top plate 2. The first mounting hole 15 and the second mounting hole 22 are both arranged along the length direction of the bottom plate 1 and the top plate 2, and a rotating rod 14 and a driving rod 21 are respectively provided on the inner sides. The top of the rotating rod 14 is higher than the bottom of the limiting groove 13 of the bottom plate 1, and the bottom of the driving rod 21 is lower than the top of the limiting groove 13 of the top plate 2. The driving rod 21 and the rotating rod 14 are directly opposite. Therefore, when the long plastic strip material is placed in the space formed by the limiting groove 13, the rotating rod 14 and the driving rod 21 can fit and clamp the long plastic strip material, and control the movement of the long plastic strip material under the rotation of the driving rod 21, and the end thereof protrudes from the space formed by the limiting groove 13, which provides convenience for realizing continuous cutting of plastic particles.

[0031] like Figure 4As shown in the figure, in order to control the rotation of the driving rod 21, a central shaft 24 is disposed through the driving rod 21. A driven gear 27 is provided at the end of the central shaft 24 protruding from the top plate 2. A driving gear 26 is meshed on the side of the driven gear 27. The driving gear 26 is sleeved on the output shaft of the first motor 25. Under the operation of the first motor 25, the rotation of the driving gear 26 can be controlled, and then the driven gear 27 and the driving rod 21 can be driven to rotate synchronously, providing power for the movement of the plastic strip raw material.

[0032] As Figure 5 , Figure 6 , Figure 7 , Figure 8 shown, in order to realize the lifting of the cutting knife 34, the control device further includes a fixing plate 33, a lifting frame 32 and a second motor 31. The fixing plate 33 is connected to the front side of the bottom plate 1 by bolts. Vertical rods 38 are fixedly provided at both ends of the fixing plate 33. The lifting frame 32 is arranged in a U-shaped structure and spans below the bottom plate 1. Driving rods 36 are provided above the ends of the lifting frame 32 protruding from the bottom plate 1. The second motor 31 is fixedly provided on the lower side of the bottom plate 1, and a cam 35 is provided on the output shaft. The cam 35 contacts the lifting frame 32. Therefore, under the action of the second motor 31, the rotation of the cam 35 can be controlled, and then the lifting frame 32 can be controlled to descend. In addition, an end plate 37 is provided at the end of the cutting knife 34. A channel is provided on the end plate 37, and the tops of the vertical rods 38 and the driving rods 36 all penetrate through the through holes of the end plate 37. At the same time, a return spring is sleeved on the vertical rod 38, and the top of the return spring contacts the end plate 37. Under the cooperation of the cam 35 and the return spring, the lifting frame 32 can drive the cutting knife 34 to lift and lower, completing the cutting of the plastic strip raw material. Specifically, when the cam 35 rotates, due to its unevenness, the lifting frame 32 can be forced to descend. When the lifting frame 32 descends, the return spring is further compressed, and then the cutting of the plastic strip particles is realized. When the lifting frame 32 descends to the lowest position, the lifting frame 32 can drive the cutting knife 34 to rise under the action of the return spring. During the rising process of the cutting knife 34, the driving rod 21 rotates, forcing the plastic strip raw material to move and protrude from the bottom plate 1 and the top plate 2. During the descending process of the cutting knife 34, the plastic strip raw material stops moving. In summary, under the cooperation of the driving rod 21, the cam 35 and the return spring, the regular movement of the cutting knife 34 and the plastic strip raw material is controlled, realizing the cutting and processing of plastic particles.

[0033] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
