[0030] A guide plate 52 is fixed on the inner side of the processing box 5 and above the hollow water separation box 40. The guide plate 52 allows the discharged powder to fall smoothly onto the second arc plate 31 to avoid falling into the gap connected to the hollow water separation box 40, thereby increasing the practicability of the equipment.

[0031] The working principle of the present invention is as follows: waste plastics enter the processing box 5 through the second feed hopper 6, the first motor 10 is started, the first motor 10 drives one of the active crushing knives 7 to rotate, the active crushing knife 7 cooperates with two second gears 9, so that the two active crushing knives 7 rotate synchronously relative to each other, and then cooperates with the fixed crushing knife 8 to crush the waste plastics, and the powder falls onto the first arc plate 11, the small-diameter powder passes through the first filter hole on the first arc plate 11, and the coarse powder remains on the first arc plate 11, and the first motor 10 cooperates with the first belt transmission mechanism 14 to drive the first rotating shaft 12 to rotate, the first rotating shaft 12 drives the spiral pushing blade 13 to rotate, and pushes the coarse powder into the circulation box 15, and then the second rotating shaft 20 is driven to rotate by the input shaft of the rotating active crushing knife 7 in cooperation with the second belt unloading mechanism 22, and the second rotating shaft 20 carries The second shaft block 19 is driven to rotate, and the second shaft block 19 cooperates with the first shaft block 18 to drive the feeding screw 17. The feeding screw 17 cooperates with the circulating feeding pipe 16 and the L-shaped discharge pipe 21 to feed the coarse powder in the circulation box 15 into the processing box 5. After secondary crushing by the active crushing knife 7, it circulates in sequence until the powder meets the requirements, and passes through the rotating second rotating shaft 20. At the same time, it cooperates with two pulleys and belts to make the pulley rotate and drive the limiting slider 28 on the pulley to rotate. The limiting slider 28 and the limiting slide groove 26 slide and cooperate to drive the sector gear 25 to reciprocate. The sector gear 25 is meshed with the first gear 24, driving the worm 29 at one end of the third rotating shaft 23 to reciprocate. The worm 29 is meshed with the worm wheel 30, and drives the L-shaped discharge pipe 21 to swing back and forth, so that the powder coming out of the L-shaped discharge pipe 21 can evenly fall on the active crushing knife 7;When the powder falls onto the second curved plate 31, the water pump 50 is started, and the water pump 50 transports the water at the bottom of the processing box 5 into the hollow water separation box 40, and sprays it onto the powder through the flushing head 41 to clean the powder. At the same time, the curved wheel 49 is driven to rotate by the rotating first rotating shaft 12, and the curved wheel 49 cooperates with the upper limit rod 48 to drive the linkage rod 46 to move back and forth. The reciprocating slider 47 on the other end of the linkage rod 46 cooperates with the reciprocating slide groove 45 to drive one of the hollow water separation boxes 40 to swing back and forth, and then cooperates with the first connecting rod 42 and the second connecting rod 43 to drive the other hollow water separation box 40 to swing back and forth, thereby improving the working range and working efficiency of the flushing head 41. At the same time, the second motor 39 is started, and the second motor 39 drives the fourth rotating shaft 37 to rotate, and the fourth rotating shaft 37 drives the cleaning spiral 34, the drainage spiral 35 and the feeding spiral 36 to rotate synchronously. When the powder falls onto the second curved plate 31, water is sprayed onto the powder on the second curved plate 31. , the powder is cleaned by the rotation of the cleaning spiral 34, and the waste water flows out through the second filter hole on the second arc plate 31. The cleaning spiral 34 rotates and pushes the powder along the second arc plate 31 to the bucket-shaped tube 32, and the water flows back to the second arc plate 31 through the drainage spiral 35 rotating in the bucket-shaped tube 32 by gravity, and falls through the second filter hole. At the same time, the drainage spiral 35 rotates and pushes the powder in the bucket-shaped tube 32 to the drying tube 33. After being heated by the heating plate 38 on the drying tube 33, the powder in the drying tube 33 is heated, dried and preliminarily plasticized. Finally, the rotating feeding spiral 36 sends the powder into the first feeding hopper 3, and then the powder is plasticized by the injection mechanism 2. The plasticized molten raw material is injected into the clamping mechanism 4 for film pressing to make a plastic product; According to the search engine search, the injection mechanism 2 and the clamping mechanism 4 are both existing technologies and have nothing to do with the technical points of this scheme, so the working principle will not be described in detail. ;

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
