[0053] A grinding roller 17 is movably disposed at one end of a roller seat 18, and the grinding roller 17 and the bottom arm of the grinding box 13 are clearance-matched; and

[0054] One end of the abutment rod 21 is connected to the sliding seat 19 , and the other end is slidably matched with the inner wall of the bottom box 2 . A plurality of adjustment parts 11 are arranged around the bottom box 2 .

[0055] It should be noted that the elastic member can be a spring 20, a spring sheet or an elastic steel plate structure. In the present embodiment, the elastic member is preferably a spring 20, and the spring 20 is connected between the roller seat 18 and the sliding seat 19. As for the specific model parameters of the spring 20, no specific limitation is made here.

[0056] In a specific case of this embodiment, a resistance reducing member is provided between the other end of the abutment rod 21 and the inner wall of the bottom box 2 to reduce the friction resistance between the abutment rod 21 and the bottom box 2 .

[0062] It should be noted that the present embodiment is not limited to the above-mentioned threaded rod 8 and threaded sleeve 9 to adjust the position of the moving wheel 7, and can also be directly driven by a linear motor, electric cylinder or hydraulic cylinder, which are not listed here one by one.

[0063] In actual application, the moving wheels 7 can be used to facilitate the movement of the entire device to the working position without the need for staff to move it. When the entire device moves to the set position, the staff can rotate the screw sleeves 9 around the device, which can make the threaded rod 8 rotate under the action of the threaded cooperation between the screw sleeves 9 and the threaded rod 8, thereby driving the moving wheels 7 to move upward relative to the bottom box 2. Finally, the moving wheels 7 are separated from the ground, and the foot seats 10 are in contact with the ground, thereby avoiding the instability of the entire device caused by the moving wheels 7 when the entire device is working.

[0064] How this application works:

[0065] The moving wheels 7 can be used to facilitate the movement of the entire device to the working position without the need for staff to move it. When the entire device moves to the set position, the staff can rotate the screw sleeves 9 around the device, which can make the threaded rod 8 rotate under the action of the threaded cooperation between the screw sleeves 9 and the threaded rod 8, thereby driving the moving wheels 7 to move upward relative to the bottom box 2. Finally, the moving wheels 7 are separated from the ground, and the foot seats 10 are in contact with the ground, thereby avoiding the instability of the entire device caused by the moving wheels 7 when the entire device is working. The food additives are poured into the top box 1, and the stepper motor 4 is controlled by the controller 5 to be powered on and rotated, so as to drive the grinding seat 3 to rotate, thereby performing primary grinding processing on the food additives in the top box 1, and the food additives after the primary processing are discharged into the grinding box 13 along the feed port 23. While the stepper motor 4 drives the grinding seat 3 to rotate, the transmission wheel, the rotating shaft 6 and the belt can also be used to drive the grinding box 13 to rotate synchronously, so that the sliding seat 19 and the grinding roller 17 can be subjected to the effect of centrifugal force. When the resistance rod 21 and the roller 22 are separated from the adjustment part 11, the sliding seat 19 and the grinding roller 17 are moved outward along the guide rail under the effect of centrifugal force, so that the food additives at various positions of the bottom wall of the grinding box 13 can be subjected to secondary grinding processing, and the food additives after the final grinding processing are discharged from the discharge window 15 along the filter screen 16, and in this process, the food additives can also be subjected to the effect of centrifugal force to move outward in the grinding box 13, so that the food additives crushed by the grinding roller 17 can be prevented from adhering to the filter screen 16 and causing the filter screen 16 to be blocked.
