A crushing rod 6 is provided at the bottom end of the inner rod 5, and a driving mechanism is provided on the device frame 1.

[0020] Through the above technical solution, when the device is in use, the raw materials of the thermistor are placed in the grinding barrel 2, and the slide 4 is driven by the driving mechanism to slide up and down along the slide groove 3, and the linked inner rod 5 moves downward while rotating, so that the crushing rod 6 enters the grinding barrel 2 in a spiral shape to continuously crush and crush the raw materials.

[0021] Specifically, the driving mechanism includes a motor 7 fixedly mounted on the top of the device frame 1 , an output end of the motor 7 is fixedly connected to a driving shaft 8 , and an end of the driving shaft 8 away from the motor 7 is fixedly connected to a rotary plate 9 .

[0022] Through the above technical solution, turning on the motor 7 can drive the drive shaft 8 to rotate, thereby linking the rotary plate 9 to rotate.

[0023] Specifically, the outer surface of the rotary plate 9 is rotatably connected to the inner shaft 10, the outer surface of the inner shaft 10 is rotatably connected to the slider 11, the top of the slide 4 is fixedly connected to the arc frame 12, and the inner surface of the arc frame 12 is slidably connected to the outer surface of the slider 11.

[0024] Through the above technical solution, the rotating plate 9 will drive the inner shaft 10 to move synchronously during the rotation process, and finally the linkage slider 11 will slide along the inner wall of the arc frame 12 while driving it.

[0025] Specifically, a guide rod 13 is fixedly connected to the outer surface of the device frame 1 , and a sliding sleeve 14 is slidably connected to the outer surface of the guide rod 13 .

[0026] Through the above technical solution, the guide rod 13 is designed to be inclined so that it can cooperate with the driving rack 15 to move up and down synchronously with the slide 4, and at the same time drive the inner rod 5 to rotate through the gear 17.

[0027] Specifically, the outer surface of the sliding sleeve 14 is fixedly connected to the driving rack 15 , and the inner side of the sliding seat 4 is provided with a guide groove 16 , and the inner surface of the guide groove 16 is slidably connected to the outer surface of the driving rack 15 .

[0028] Through the above technical solution, the guide groove 16 is designed to allow the driving rack 15 to move laterally along a fixed track.

[0031] Working principle: When the device is in use, the raw material of the thermistor is first placed in the crushing barrel 2, and then the motor 7 is turned on to drive the driving shaft 8 to rotate. The driving shaft 8 will drive the rotary plate 9 to rotate during the rotation process, and then the inner shaft 10 will rotate. The inner shaft 10 will drive the slider 11 to slide along the inner wall of the arc frame 12, and at the same time drive the arc frame 12. The arc frame 12 is relatively limited by the slide seat 4, so the arc frame 12 will drive the slide seat 4 to slide down along the slide groove 3. In this process, the inner rod 5 will drive the crushing rod 6 to move downward synchronously. At the same time, the sliding sleeve 14 will slide down along the surface of the guide rod 13, and at the same time drive the driving rod 6 to move downward. The movable rack 15 slides laterally along the guide groove 16. The driving rack 15 will drive the gear 17 meshing with it to rotate during the lateral movement, and finally drive the inner rod 5 to rotate, so that the crushing rod 6 gradually enters the crushing barrel 2 in a spiral shape, and continuously and evenly crushes the raw materials in the crushing barrel 2, making the crushing result more uniform and fine. The crushing rod 6 enters the crushing barrel 2 in a spiral shape, which can make full use of the space and achieve more effective crushing of the raw materials, so that the raw materials are subjected to more uniform pressure distribution during the crushing process, which is conducive to obtaining a uniform crushing effect, fully covering the raw materials, and improving the crushing efficiency.
