DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-4 As shown, a waste plastic processing and recycling device of the present invention comprises a pulverizing frame 1, in which two pulverizing rollers 11 are installed for parallel rotation, a transmission mechanism connected to the two pulverizing rollers 11 is arranged on the outer side of the pulverizing frame 1, the two pulverizing rollers 11 are meshed with each other, a collecting box 12 is connected to the lower side of the pulverizing frame 1, pressing plates 13 are arranged on the front and rear sides of the upper part of the collecting box 12, the two pressing plates 13 are slidably installed in the collecting box 12, a driving mechanism connected to the two pressing plates 13 is arranged on the upper side of the collecting box 12, an inner cavity 14 is arranged in the two pressing plates 13, a slide plate 15 is slidably installed in the two inner cavities 14, a rebound mechanism matching the slide plate 15 is arranged in the two inner cavities 14, a pressure rod 16 that can extend out of the pressing plate 13 is arranged on the opposite side of the two slide plates 15, a protruding port 17 is arranged on the right side of the lower part of the collecting box 12, the protruding port 17 is equipped with a cover plate 18, and a pushing mechanism matching the protruding port 17 is arranged in the collecting box 12.

[0028] When the staff needs to crush the waste plastic, the waste plastic can be put into the crushing frame 1 from the upper side of the crushing frame 1, and the transmission mechanism drives the two crushing rollers 11 to rotate simultaneously, and the two crushing rollers 11 mesh with each other and rotate, and the waste plastic can pass through the two crushing rollers 11, and the crushing blades on the outer surfaces of the two crushing rollers 11 can crush the waste plastic. After passing through the two crushing rollers 11, the waste plastic falls downward under the action of gravity and falls on the lower surface of the collection box 12;

[0029] When the crushed waste plastics are accumulated on the lower side of the collecting box 12 under the action of gravity, the driving mechanism starts to work, driving the two pressing plates 13 to move downward. During the downward movement of the pressing plates 13, the rebound mechanisms in the two pressing plates 13 start to work at the same time, driving the two slide plates 15 to approach each other. During the approach of the two slide plates 16, the plurality of pressing rods 16 are driven to extend between the two pressing plates 13. Therefore, the plurality of pressing rods 16 will follow the two pressing plates 13 to move downward. When the pressing rods 16 and the pressing plates 13 move downward at the same time, the waste plastics in the collecting box 12 will be squeezed downward until the waste plastics are squeezed downward to the height of the extension port 17. At this time, the staff can open the cover plate 18, and the staff will place the waste plastic storage bag at the extension port 17 position, and then drive the pushing mechanism to start working, and push the waste plastics squeezed by the lower sides of the pressing plates 13 and the pressing rods 16 out of the extension port 17, so that the compressed waste plastics can be pushed into the storage bag, which is convenient for the staff to store the waste plastics. Such a design is convenient for the staff to store and transport the crushed waste plastics.

[0030] After the waste plastic is removed from the extension port 17, the two pressing plates 13 can be driven by the driving mechanism to move upward and reset. After the two pressing plates 13 are driven upward to the upper side of the collection box 12, the rebound mechanism starts to work again, driving the two slide plates 15 away from each other, thereby driving a plurality of pressing rods 16 to be retracted into the inner cavity 14, and will not block the waste plastic falling from between the two crushing rollers 11.

[0031] The transmission mechanism includes two gears 2 rotatably assembled on the outside of the crushing frame 1, the two gears 2 are meshed with each other, and the two gears 2 are respectively connected to the two crushing rollers 11 by transmission. A shielding cover 21 matching the two gears 2 is provided on the outside of the crushing frame 1, and a motor 22 connected to one of the gears 2 by transmission is provided on the outside of the shielding cover 21.

[0032] When the motor 22 starts to work, it will drive one of the gears 2 to start rotating. Since the two gears 2 are meshed with each other, the two gears 2 start to rotate at the same time, thereby driving the two crushing rollers 11 to rotate at the same time.

[0033] The driving mechanism includes two first hydraulic rods 23, both of which are arranged on the upper side of the collection box 12. The driving rods of the two first hydraulic rods 23 extend into the collection box 12 and are respectively connected to the two pressing plates 16. When the two first hydraulic rods 23 begin to extend, the two pressing plates 16 are driven to move downward rapidly in the collection box 12. When the two first hydraulic rods 23 begin to contract, the pressing plates 16 are driven to move upward rapidly in the collection box 12.

[0034] The rebound mechanism includes two slide bars 24, which are respectively arranged on both sides of the inner cavity 14. The two ends of the slide plate 15 are respectively sleeved on the outer surfaces of the two slide bars 24. The side of the slide plate 15 facing the pressure rod 16 is provided with a spring 25 sleeved on the outer surface of the slide bar 24. The slide plate 15 is equipped with a first magnet block 251, and the inner wall of the collection box 12 is provided with a second magnet block 252 that magnetically repels the first magnet block 251.

[0035] When the pressing plate 13 is on the upper side of the collecting box 12, the spring 25 is stretched to drive the slide plate 15 into the inner cavity 14, thereby driving a number of pressure rods 16 into the inner cavity 14 through the slide plate 15. When the pressing plate 13 moves downward, the first magnet block 251 is matched with the second magnet block 252. Since the first magnet block 251 and the second magnet block 252 repel each other magnetically, the slide plate 15 is pushed in the inner cavity 14, and the number of pressure rods 16 are pushed out of the inner cavity 14. When the pressing plate 13 moves upward to reset, the first magnet block 251 and the second magnet block 252 are staggered, so the spring 25 is stretched to drive the slide plate 15 into the inner cavity 14.

[0036] The pushing mechanism includes a push plate 26 , which is mounted on the side of the collecting box 12 away from the extension port 17 . Two second hydraulic rods 27 are mounted on the outside of the collecting box 12 . The transmission rods of the two second hydraulic rods 27 extend into the collecting box 12 and are connected to the push plate 26 .

[0037] When the second hydraulic rod 27 begins to extend, it drives the push plate 26 to slide in the collection box 12, and the push plate 26 pushes the waste plastic in the collection box 12 to be ejected from the extension port 17.

[0038] The inner wall of the collecting box 12 is provided with a groove 271 which matches the push plate 26. When the waste plastics are not pushed, the push plate 26 is located in the groove 271 and will not block the waste plastics falling downwards.

[0039] Two inclined plates 28 are provided on the upper side of the crushing frame 1, and the two inclined plates 28 are inclined downward on opposite sides, and the two inclined plates 28 are arranged parallel to the two crushing rollers 11. The design of the two inclined plates 28 can guide the waste plastics entering the crushing frame 1 and guide the waste plastics into between the two crushing rollers 11.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
