A guide plate 12 is fixedly connected to the surface of one side of the lifting plate 9. The guide plate 12 is inclined. The guide plate 12 can better guide the raw materials on the inclined plate 11 through the material discharge slot and the material feed slot to the inside of the crusher body 2. The surfaces on both sides of the lifting plate 9 are fixedly connected to the limiting plates 13. Limiting grooves 14 are provided on both sides, and the surface of the limiting plate 13 is slidably connected to the inner wall of the limiting groove 14. The limiting plate 13 and the limiting groove 14 are used in conjunction with each other to guide and limit the lifting plate 9, thereby increasing the practicality of the lifting plate 9. An auxiliary mechanism 15 is installed on the top of the processing box 8, and a horizontal plate 16 is fixedly connected to the bottom of the auxiliary mechanism 15. An ferromagnetic magnet 17 is fixedly connected to the bottom of the horizontal plate 16. The width of the ferromagnetic magnet 17 is equal to that of the horizontal plate 16, and is equal to the width of the inner wall of the processing box 8. Based on this, In order to improve the adsorption effect of the magnetic magnet 17 on metal impurities in the injection molding raw materials, a vertical plate 18 is fixedly connected to the bottom of the processing box 8, and the number of the vertical plates 18 is two. A driving mechanism 19 is installed on the surface of the vertical plate 18. A rectangular groove 20 is opened at the bottom of the processing box 8 and is located on one side of the discharge chute. The number of the rectangular grooves 20 is three. A column 10 is fixedly connected to the top of the workbench 1. The top of the column 10 is fixedly connected to the bottom of the processing box 8. The column 10 can support the processing box 8 to increase the practicality of the device.

[0023] The inside of the pulverizer body 2 is provided with blades and a stirring device. The blades can pulverize the injection molding raw materials entering from the inside of the feed trough, and the stirring device can stir and mix the pulverized injection molding raw materials. This is an existing mature technology and will not be elaborated here.

[0024] The conveying mechanism 6 includes an auger shaft 61, a servo motor 62 and an auger blade 63. The bottom of the auger shaft 61 is rotatably connected to the bottom of the inner wall of the storage tank 4, and the top of the auger shaft 61 rotates and penetrates to the top of the empty barrel 5. The servo motor 62 is fixedly connected to the top of the empty barrel 5, and the top of the auger shaft 61 is fixedly connected to the output shaft of the servo motor 62. The auger blade 63 is fixedly connected to the surface of the auger shaft 61. When the staff starts the servo motor 62, the auger shaft 61 drives the auger blade 63 to rotate, so that the injection molding material in the storage tank 4 can be conveyed upward, and is conveyed to the processing box 8 through the conveying pipe 7 and the second slot. One side of the inner wall of the storage tank 4 is designed to be inclined, so that the raw material can be better conveyed upward through the conveying mechanism 6.

[0025] The auxiliary mechanism 15 includes a slide bar 151, a top plate 152 and a tension spring 153. There are two slide bars 151 and two tension springs 153. The slide bar 151 slides through the processing box 8. The top plate 152 is fixedly connected to the top of the slide bar 151. The tension spring 153 is sleeved on the surface of the slide bar 151. The two ends of the tension spring 153 are respectively fixedly connected to the top of the processing box 8 and the bottom of the top plate 152. The cross plate 16 is fixedly connected to the bottom of the slide bar 151. When the lifting plate 9 is lifted and drives the raw material placed on the inclined plate 11 to lift, and the raw material is vibrated, the magnet 17 contacts the raw material to absorb the metal impurities in the raw material, so as to reduce the problem that the metal impurities enter the inside of the crusher body 2 and damage the blade inside the crusher body 2 for crushing the raw material. The staff can regularly clean the metal impurities at the bottom of the magnet 17 through the first slot, so that the bottom of the magnet 17 can always be close to the raw material under the action of the elastic force of the tension spring 153.

[0026] The driving mechanism 19 includes a stepper motor 191, a rotating shaft 192 and a cam 193. The stepper motor 191 is fixedly connected to the surface of the vertical plate 18 on one side, one end of the rotating shaft 192 is rotatably connected to the surface of the vertical plate 18 on the other side, the other end of the rotating shaft 192 rotates and penetrates the vertical plate 18 on the other side, and the other end of the rotating shaft 192 is fixedly connected to the output shaft of the stepper motor 191. There are three cams 193, which are fixedly sleeved on the surface of the rotating shaft 192. The surface of the cam 193 contacts the surface of the rectangular groove 20. Accordingly, when the staff starts the stepper motor 191, the rotating shaft 192 rotates accordingly to drive the cam 193 to rotate. The raised part of the cam 193 contacts the bottom of the lifting plate 9 through the rectangular groove 20, so that the height of the lifting plate 9 can be lifted, so as to vibrate the raw material placed on the top of the inclined plate 11, so that the raw material can fall smoothly.

[0027] It should be noted that the horizontal plate 16, the lifting plate 9, the processing box 8 and the inclined plate 11 in the present device are all made of non-metallic materials.

[0028] Working principle: the staff pours the smaller injection molding raw material into the storage tank 4 and starts the servo motor 62 and the stepper motor 191. The auger shaft 61 and the auger blade 63 cooperate to convey the raw material in the storage tank 4 upward and inject it into the processing box 8 through the conveying pipe 7 and the second slot. The raw material falls to the top of the inclined plate 11. At the same time, the cam 193 can intermittently adjust the height of the lifting plate 9. When the surface of the cam 193 is no longer in contact with the bottom of the lifting plate 9, the lifting plate 9 can fall under the action of gravity. In this process, the inclined plate 11 drives the raw material to vibrate to assist the raw material to fall. In this process, the ferromagnetic magnet 17 can adsorb and clean some metal impurities in the injection molding raw material. The processed injection molding raw material falls into the inside of the crusher body 2 through the discharge trough and the feed trough. The blades and stirring equipment inside the crusher body 2 can crush and mix the injection molding raw material.

[0029] For larger injection molding raw materials, the staff can directly place them into the processing box 8 through the first slot. After that, the larger injection molding raw materials can fall into the inside of the crusher body 2 through the discharge chute and the feed chute and be crushed and stirred. In this process, the staff can clean up the metal impurities mixed inside the larger injection molding raw materials.
