[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] During the production process of injection molding raw materials, it is necessary to crush the block or granular injection molding raw materials into the required particles or powder for subsequent injection molding. The crusher provided by the utility model can clean the crushing knife 8 and remove the debris accumulated on the crushing knife 8 to avoid the accumulation of too much debris on the crushing knife 8 and the rotating shaft 7, which affects the crushing work of the crushing knife 8.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a crusher for injection molding raw material production, including a crushing box 1, two rotating shafts 7 are rotatably connected between the inner walls of both sides of the crushing box 1, and multiple crushing knives 8 are fixed to the outer walls of the two rotating shafts 7. A cleaning mechanism 2 is arranged on one side of the crushing box 1, and the cleaning mechanism 2 includes a fixed shell 201 fixedly connected to one side of the crushing box 1, and a double-headed screw rod 203 is rotatably connected between the inner walls of both ends of the fixed shell 201. A first motor 202 is fixed to one end of the fixed shell 201, and the output end of the first motor 202 passes through the fixed shell 201 and is fixed to the double-headed screw rod 203. The outer walls at both ends of 203 are respectively screwed with sliders 204, and a limit rod is fixed between the inner walls at both ends of the fixed shell 201. The slider 204 is slidably connected to the outer wall of the limit rod. A mounting frame 205 is fixed on one side of the slider 204, and a cleaning piece 206 is fixed at the bottom end of the mounting frame 205. A connecting piece 207 is fixed at one end of the mounting frame 205. The interior of the connecting piece 207 is a cavity, and a plurality of water guns 208 are fixedly connected at the bottom end. Water tanks 3 are fixed at both ends of the crushing box 1, and a water pump is installed in the water tank 3. The water outlet of the water pump is fixedly connected with a connecting pipe, which passes through the crushing box 1 and is fixedly connected with the connecting piece 207.

[0021] It should be noted that the double-headed screw 203 is driven to rotate by the first motor 202, and the rotation of the double-headed screw 203 drives the slider 204 to move, thereby moving the cleaning member 206 and the connecting member 207. During the movement, the water pump sends the water in the water tank 3 into the connecting member 207 through the connecting pipe, and then sprays it out through the water gun 208 to clean the rotating shaft 7 and the crushing knife 8. When the cleaning member 206 moves to the highest point of the rotating shaft 7, the cleaning member 206 cleans the outer wall of the rotating shaft 7 and the outer walls on both sides of the crushing knife 8 through the rotation of the rotating shaft 7, so that the crushing knife 8 and the rotating shaft 7 can be well cleaned, avoiding the accumulation of a lot of debris on the crushing knife 8 and the rotating shaft 7, which affects the crushing work of the crushing knife 8.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a feed box 5 is fixed to the top of the crushing box 1, and a feed pipe 13 is fixed to the top of the feed box 5.

A second motor is fixed to one side of the feed box 5, and the output end of the second motor passes through the feed box 5 and is fixed to the rotating rod 10. A plurality of discharge ports 12 are provided between the bottom end of the feed box 5 and the top of the crushing box 1. A mounting shell 4 is fixed to the other side of the crushing box 1, and a fixing rod 9 is fixed between the inner walls of both ends of the mounting shell 4. A connecting block is fixed to one end of the mounting frame 205, and the connecting block slides on the fixing rod 9. A supporting frame is fixed to the outer wall of the bottom end of the crushing box 1, and a universal wheel is installed at the bottom end of the supporting frame, and the universal wheel has a brake function. A controller 6 is installed on one side of the crushing box 1, and the controller 6 is electrically connected to the first motor 202, the water pump and the second motor.

[0023] It should be noted that the raw materials are fed into the feed box 5 through the feed pipe 13, and then the second motor drives the rotating rod 10 to rotate, and the rotation of the rotating rod 10 drives the auger 11 to rotate, and the rotation of the auger 11 transports the raw materials, so that the raw materials will not fall from one position, avoiding the raw materials from being crushed in one position.

[0024] Working principle: when it is necessary to clean the crushing knife 8 in the crushing box 1, the first motor 202 is started through the controller 6, and the first motor 202 drives the double-headed screw 203 to rotate, and the rotation of the double-headed screw 203 drives the slider 204 to move, so that the cleaning piece 206 and the connecting piece 207 move. During the movement, the water pump sends the water in the water tank 3 into the connecting piece 207 through the connecting pipe, and then sprays it out through the water gun 208 to clean the rotating shaft 7 and the crushing knife 8, and when the cleaning piece 206 moves to the highest point of the rotating shaft 7, the rotating shaft 7 rotates, and the cleaning piece 206 cleans the outer wall of the rotating shaft 7 and the outer walls on both sides of the crushing knife 8.
