[0034] Please see Figure 1-4 As shown, a pulverizer for powder coating production includes:

[0035] The pulverizing chamber assembly 1 includes a chamber body 101, a chamber cover 102, and an outlet 103;

[0036] The crushing component 2 is fixedly installed on the upper surface of the bin cover 102, and one end of the crushing component 2 extends into the inner cavity of the bin body 101. The crushing component 2 is used to crush and process raw materials.

[0037] Auxiliary cooling component 3 is fixedly installed on the upper surface of the bin cover 102. The auxiliary cooling component 3 is used to automatically cool the raw materials during crushing and processing.

[0038] Through the above technical solution, by setting the auxiliary cooling component 3, the resin raw material can be automatically cooled by heat conduction when the crushing component 2 crushes the raw material, thereby achieving the beneficial effect of automatic cooling, and at the same time, no additional power source is required. It is especially suitable for use when crushing raw materials that are easily damaged by high temperature.

[0039] The bottom of the hopper 101 is provided with an outlet 103, and a valve is installed on the outlet 103. Through this technical solution, after the raw material is crushed, the outlet 103 can be opened to discharge the material.

[0040] The crushing assembly 2 includes a fixed bracket 201, a rotating rod 202, a bevel gear A 203, a servo motor 204, a bevel gear B 205, a crushing blade 206, and a heat-conducting rod 207. The fixed bracket 201 is fixedly installed on the upper surface of the chamber cover 102. The rotating rod 202 is rotatably connected to the middle of the fixed bracket 201, and one end of the rotating rod 202 extends into the inner cavity of the chamber body 101.

[0041] A bevel gear A203 is fixedly connected to the arc-shaped wall of the rotating rod 202. A servo motor 204 is fixedly connected to the side wall of the fixed bracket 201. The output shaft of the servo motor 204 extends to the inner side of the fixed bracket 201. A bevel gear B205 is fixedly connected to the output shaft of the servo motor 204. The bevel gear B205 meshes with the bevel gear A203. A crushing blade 206 is fixedly connected to the bottom end of the rotating rod 202. Through this technical solution, the operation of the servo motor 204 can drive the bevel gear B205 to rotate, thereby driving the bevel gear A203 to rotate, which in turn drives the rotating rod 202 to rotate. The rotation of the rotating rod 202 can drive the crushing blade 206 to rotate, thereby crushing the resin raw material.

[0042] A plurality of heat-conducting rods 207 are fixedly connected to the arc-shaped wall of the rotating rod 202. The rotating rod 202 has a hollow inner cavity, and the heat-conducting rods 207 have inner cavities. The inner cavities of the rotating rod 202 and the heat-conducting rods 207 are interconnected. Through this technical solution, when the resin raw material is crushed, the rotation of the heat-conducting rods 207 can also contact the raw material. Through heat exchange, the temperature of the raw material is reduced, avoiding overheating damage.

[0043] The upper end of the rotating rod 202 is rotatably connected to a rotary joint A208, and the lower end of the rotating rod 202 is rotatably connected to a rotary joint B209. A discharge pipe 210 is fixedly connected to the rotary joint B209.

[0044] The auxiliary cooling component 3 includes a fixed plate frame 301, a rotating disk 302, a rotating rod 303, a bevel gear C304, a connecting cylinder 305, a moving piston 306, a moving rod 307, and a bracket 308. The fixed plate frame 301 is fixedly installed on the upper surface of the cover 102. The rotating rod 303 is rotatably connected to the fixed plate frame 301. One end of the rotating rod 303 is fixedly connected to the rotating disk 302, and the other end of the rotating rod 303 is fixedly connected to the bevel gear C304. The bevel gear C304 meshes with the bevel gear A203. Through this technical solution, the rotation of the bevel gear A203 can drive the bevel gear C304 to rotate, which in turn drives the rotating rod 303 to rotate, thereby driving the rotating disk 302 to rotate.

[0045] A bracket 308 is fixedly connected to the upper surface of the cover 102, and a connecting cylinder 305 is rotatably connected to the upper end of the bracket 308.

[0046] A movable piston 306 is slidably connected in the inner cavity of the connecting cylinder 305. One end of a movable rod 307 is fixedly connected to the side wall of the movable piston 306. The other end of the movable rod 307 passes through the side wall of the inner cavity of the connecting cylinder 305 and extends to the outside of the wall. One end of the movable rod 307 extends to the side wall of the rotating disk 302 and is rotatably connected to the rotating disk 302. Through this technical solution, the rotation of the rotating disk 302 can drive one end of the movable rod 307 to move in a ring, which in turn can drive the movable piston 306 to reciprocate in the inner cavity of the connecting cylinder 305.

[0047] An output hose 309 and an intake hose 310 are fixedly connected in the inner cavity of the connecting cylinder 305. One end of the output hose 309 extends to and is connected to the rotary joint A208. An output check valve is installed on the output hose 309, and an input check valve is installed on the intake hose 310.

[0048] When this device is in use, one end of the suction hose 310 is extended into the cold water chamber, which is filled with cold water. One end of the discharge pipe 210 is also extended into the cold water chamber. The moving piston 306 moves back and forth within the inner cavity of the connecting cylinder 305, thereby continuously injecting cold water into the inner cavity of the rotating rod 202 and then returning it to the cold water chamber through the discharge pipe 210. This circulating cold water can quickly remove the heat from the raw materials, avoiding the problem of overheating.
