As shown in fig. 10, the plastic powder processing apparatus 6 includes a second rotating shaft 603, a second thrust ball bearing 605 and a second gear 604 are installed at the upper end of the second rotating shaft 603, a special-shaped shaft 606 and a special-shaped shaft fixing screw 607 are installed at the lower end, and a storage barrel 602 and a short pin 601 are sequentially installed on the special-shaped shaft 606; the plastic powder handling device 6 is mounted in the through hole 502 and cooperates with the first gearwheel 302.
As shown in fig. 11, the screen structure 608 has a screen in the middle for filtering the water for milling.
As shown in fig. 12, the irregular shaft fixing screw 607 has a radial three-rod structure.
As shown in fig. 13, the plastic powder drying device 7 is a cylindrical fan.
The using process of the invention is as follows: when the plastic crushing and grinding device is used, after waste plastics are pretreated to be in a proper size, the waste plastics enter the plastic crushing and grinding device 2 from the top cover 203 of the plastic crushing and grinding device, the crushing and grinding driving motor 1 drives the first rotating shaft 201 to rotate, the crushing stop plate 206 and the crushing moving blade 207 which are arranged on the crushing and grinding driving motor can crush the waste plastics, when the waste plastics are crushed to be in a proper size, the waste plastics can fall from the hole of the blanking plate 208, at the moment, the crushed plastics can be mixed with water which passes through the filter 402 and the water pump 403 in the water circulating device 4 and flows through the water pipe 401, and the water is stored in the water tank 501. After the mixing, wet milling was performed by using the movable grinding blade 211 and the fixed grinding blade 210. The wet grinding can realize uniform grinding, and avoid the adverse effects of dust, noise, plastic powder static electricity and the like. The ground plastic powder falls into the storage bin 602 and excess moisture can be filtered out of the mesh structure 608 at the bottom of the storage bin 602. When the plastic powder is stored to a certain amount, the driving steering engine 301 of the plastic powder processing device rotation driving device 3 drives the first gear 302 to rotate and rotate to the second gear 604 of the plastic powder processing device 6, after the plastic powder processing device integrally rotates, the storage barrel 602 filled with the plastic powder rotates to the position below the plastic powder drying device 7, the drying processing is started, and meanwhile, an empty storage barrel 602 rotates to the position below the plastic crushing and grinding device 2. After the plastic powder is dried, the plastic powder processing device 6 rotates out of the base 5 by the plastic powder processing device rotation driving device 3, and the storage barrel 602 filled with the dried plastic powder can be taken down by pulling out the short pin 601.
The foregoing is only a preferred embodiment of the present invention, and many variations in the specific embodiments and applications of the invention may be made by those skilled in the art without departing from the spirit of the invention, which falls within the scope of the claims of this patent.
