[0019] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0020] Plastic crushers are mainly used to crush various plastics and rubbers, such as plastic profiles, tubes, rods, silk threads, films, and waste rubber products. The pellets obtained after crushing can be directly used in extruders or injection molding machines, or they can be recycled through basic granulation. The feed port of existing plastic crushers is generally covered with cloth or rubber to prevent the crushed material from splashing and injuring people. However, it is still difficult to avoid the crushed material from ejecting from the feed port, causing injuries. It also causes the spread of plastic dust and harmful substances, easily forming a dust cloud and causing dust explosion accidents. As a safety protection device in the application of plastic crushers, it is the core concept of this utility model.

[0021] like Figure 1 、 2 The protective cover 3 is arranged at the top end of the protective cover 3 so as to prevent the dust from spreading during the feeding process and the crushed material from splashing out of the crusher, thereby causing personal injury to the staff. The protective cover 3 is arranged upwardly and tilted, and the inclined top end of the protective cover 3 is connected to a feeding barrel 4, and an electric screw conveying blade is arranged inside the feeding barrel 4. The feeding barrel 4 is provided with a motor-driven screw conveying blade. The provided feeding barrel and the motor-driven screw conveying blade slowly send the material to be crushed from the feeding barrel to the protective cover and the feeding port, and finally enter the interior of the crusher, ensuring that the transportation is more convenient. A magnetic separation component is provided at the bottom end of the crusher 1. After the crushing is completed, the crushed material is sent into the magnetic separation component for magnetic separation of the crushed material for further differentiation.

[0022] like Figure 1 、 2 As shown, a crushing roller 6 is provided inside the crusher 1, and a guide tube 7 corresponding to the feeding port 2 is provided inside the crusher 1, and a corresponding row pipe 8 corresponding to the crushing roller 6 is provided at the bottom end of the guide tube 7, and a driving motor for driving the crushing roller 6 is fixed on the outer wall of the crusher 1.

[0023] There are two crushing rollers 6 and two external drive motors. The design of the corresponding discharge pipe 8 and the guide tube 7 ensures that the material is finally smoothly transported between the two crushing rollers 6 to complete the crushing work.

[0024] As shown in FIG1 , an electrical panel 9 is fixed on the outer wall of the grinder 1 , a dust pump 10 is mounted on the electrical panel 9 , a dust nozzle 11 is connected to the dust pump 10 through a pipe, and the dust nozzle 11 is fixed on the inner wall of the grinder 1 .

[0025] The function of the dust suction pump 10 and the dust suction nozzle 11 is to absorb the dust generated by the crushed material to prevent the dust from spreading outward. The dust suction pump 10 is provided with an outlet pipe, and the tail of the outlet pipe is tied with a collection bag through a thin rope. It is an existing collection structure and the process will not be described here.

[0026] See Figure 1-4 The magnetic separation component includes a magnetic separation shell 12 fixed on the pulverizer 1, a rotating drum 13 is rotatably arranged inside the magnetic separation shell 12, a semicircular magnet 14 is arranged in the rotating drum 13, and a fixed round rod 15 is fixed at one end of the magnet 14, the fixed round rod 15 slides through the rotating drum 13, and the fixed round rod 15 is fixedly passed through the magnetic separation shell 12, the pulverizer 1 is provided with a discharge pipe 16, the outlet of the discharge pipe 16 corresponds to the rotating drum 13, and the middle of the bottom end of the magnetic separation shell 12 is fixed. A scraper plate 17 is provided that contacts the rotating drum 13, an auxiliary dust suction pump 18 is installed on the electrical board 9, and an auxiliary dust suction nozzle 19 is connected to the auxiliary dust suction pump 18 through a pipe. The auxiliary dust suction nozzle 19 is fixed to the inner wall of the magnetic separation shell 12, and the end of the rotating drum 13 away from the fixed round rod 15 is fixed with a rolling round rod 20 that slides out of the magnetic separation shell 12, and an auxiliary drive motor that drives the rolling round rod 20 is fixed on the outer wall of the magnetic separation shell 12. The bottom end of the magnetic separation shell 12 is respectively connected to two discharge bins 21.

[0027] The magnet 14 then adsorbs the magnetic materials of the crushed raw materials, and finally discharges them along the discharge bin 21. The auxiliary drive motor drives the rotation of the drum 13, and the magnetic separation is completed by coordinating the adsorption of the magnet and the non-adsorption of the other half.

[0028] The present invention directly solves the problem of dust diffusion during the material crushing process, and also solves the problem that the crushed material is easily splashed out of the material inlet, causing harm to the staff. Therefore, the present application designs a protective cover at the feeding port, so that during the feeding process, dust will not spread, and the crushed material will not splash out of the crusher, causing personal injury to the staff, and effectively avoids the spread of plastic dust and harmful substances, which may easily form dust clouds and cause dust explosion accidents. Through the provided feeding barrel and the electric threaded conveying blades, the material to be crushed is slowly fed from the feeding barrel to the protective cover and the feeding port, and finally enters the interior of the crusher, ensuring that the transportation is more convenient. And after the crushing is completed, the crushed material is sent to the magnetic separation component for magnetic separation of the crushed material, and further differentiation work is carried out to improve the practicality of the device.
