Wherein, in order to prevent the material from being stuck on the top of the feeding box 16 and being unable to normally fall down onto the auxiliary grinding disc 20 for grinding, a movable groove for the movement of the movable magnetic block 15 is formed on the inner wall of the fixed seat 10, the movable groove is shaped as a T-shaped groove, a V-shaped inner cavity is formed on the inner wall of the fixed seat 10, the movable magnetic block 15 is movably mounted in the inclined inner wall of the fixed seat 10, meanwhile, a material pulling block 21 is fixedly mounted on the top of the auxiliary grinding disc 20, the number of the material pulling blocks 21 is six, the six material pulling blocks 21 are mounted on the surface of the auxiliary grinding disc 20 at equal angles by taking the central axis of the auxiliary grinding disc 20 as the center, so that when the material is blocked on the top of the feeding box 16, the material quantity of the materials at the main grinding disc 19 and the auxiliary grinding disc 20 is continuously reduced, so that the load between the auxiliary grinding disc 20 and the main grinding disc 19 is reduced, therefore make driving motor 2's load reduce, and then strengthen its drive shaft 3's rate of rotation, meanwhile, rate of rotation through drive shaft 3 strengthens, and then leads to fixing base 10's rate of rotation to increase, therefore make movable magnetic path 15 when receiving outside throwing power, its movable magnetic path 15 can follow the activity groove upward movement on the fixing base 10, make the distance between its floating magnetic path 14 and the movable magnetic path 15 shorten, and then under the effect of magnetic repulsion, upwards push up its floating magnetic path 14, make material shifting block 21 contact the material of its feed box 16 jam, and then realize its purpose of putty automatic processing.

Referring to fig. 3 and 7, in order to make the floating block 13 opposite to the magnetic surface of the movable magnetic block 15 on the fixed seat 10 during the rotation process, the floating block 13 is set to be in a convex platform shape, the floating magnetic block 14 is fixedly installed on the inclined surface of the floating block 13, at the same time, the number of the floating magnetic blocks 14 and the number of the movable magnetic blocks 15 are six, the six floating magnetic blocks 14 are fixed to the side wall of the floating block 13 at equal angles by taking the central axis of the floating block 13 as the center, and the movable magnetic blocks 15 are movably installed on the inner wall of the fixed seat 10 at equal angles, so that the magnetic forces applied to the floating magnetic blocks 14 and the movable magnetic blocks 15 during the rotation process are simultaneously ended, and the purpose of up-and-down floating when the floating magnetic blocks 14 and the movable magnetic blocks 15 are influenced by the magnetic force is ensured.

Referring to fig. 6 and 7, in order to make the transmission shaft 12 transmit the torque of the support shaft 6 and make the transmission shaft 12 and the transmission sleeve 17 rotate relatively, the side wall of the transmission shaft 12 is made cylindrical, and the connecting end of the transmission shaft 12 and the support shaft 6 is provided with an oval shape, so that the support shaft 6 and the transmission shaft 12 can synchronously rotate and can slide up and down due to the oval design.

Referring to fig. 6, in order to make the movable magnetic block 15 have enough throwing power to lift up the floating magnetic block 14 during the rotation process, the number of teeth of the driving gear 4 is twice as large as that of the driven pulley 7, so that when the module and the pressure angle between the gears are the same, the rotation rate of the driven pulley 7 is increased during the rotation process of the driving gear 4, thereby not only increasing the rotation grinding efficiency of the main grinding disc 19, but also ensuring that the movable magnetic block 15 has enough throwing power in the idle state.

In order to enable large-particle materials in the feeding box 16 to be sheared and crushed, the diameter value of the main grinding disc 19 is set to be one point twice of the diameter value of the auxiliary grinding disc 20, so that the materials can be subjected to rough grinding treatment through the transmission shaft 12 in the rotating process, and fine grinding of the main grinding disc 19 is performed after the materials are sheared between the main grinding disc 19 and the auxiliary grinding disc 20, so that the grinding sequence is sequentially enhanced, the abrasion in the fine grinding process of the main grinding disc 19 can be reduced, and meanwhile, the grinding quality is also ensured.

The using method of the invention has the following working principle:

a preparation state: firstly fixing its base 1 in position, secondly, by energizing its drive motor 2 and placing its material to be ground in a feed box 16;

grinding state (rotation direction refer to fig. 5): through the rotation of the driving motor 2, the driving motor 2 drives the driving shaft 3 to rotate, so that the driving gear 4 and the driving pulley 5 synchronously rotate along with the driving shaft 3, the driving gear 4 synchronously rotates relative to the driven gear 11 through external teeth, so that the driven gear 11 drives the fixed seat 10 to synchronously rotate, the transmission sleeve 17 synchronously rotates with the fixed seat 10 through the rotating sleeve 9, so that the transmission sleeve 17 drives the main grinding disc 19 to rotate, the main grinding disc 19 and the fixed grinding disc 18 relatively rotate, so as to grind the material through the main grinding disc 19, meanwhile, in the process of driving the driving gear 4 and the driving pulley 5 to be synchronous and same-directional rotation through the belt 8, the driving pulley 5 and the driven pulley 7 drive the supporting shaft 6 to rotate through the driving pulley 3, meanwhile, the auxiliary grinding disc 20 synchronously rotates along with the supporting shaft 6 through the transmission shaft 12, at the moment, the direction of rotation of the auxiliary grinding disc 20 is opposite to that of the main grinding disc 19, so that after the materials are primarily ground through the auxiliary grinding disc 20, the materials are put between the main grinding disc 19 and the auxiliary grinding disc 20 for shearing grinding, and then the materials are finally finely ground through the main grinding disc 19;

the method is suitable for different particle grinding states: in the process of grinding the auxiliary grinding disc 20 and the main grinding disc 19, the transmission shaft 12 and the driven gear 11 rotate relatively, so that the floating magnetic block 14 on the transmission shaft 12 and the movable magnetic block 15 also rotate and rotate in opposite directions, further the floating magnetic block 14 on the floating block 13 is influenced by the magnetic repulsion between the floating magnetic block and the movable magnetic block 15 when facing the magnetic surface of the movable magnetic block 15, the floating magnetic block 14 causes the floating block 13 to drive the transmission shaft 12 to push upwards under the action of the repulsion of the movable magnetic block 15, the auxiliary grinding disc 20 is far away from the main grinding disc 19 to rotate reversely, meanwhile, when the floating magnetic block 14 rotates far away from the movable magnetic block 15, the distance between the auxiliary grinding disc 20 and the main grinding disc 19 is shortened through the magnetic attraction and the self gravity of the floating magnetic block 14 to the fixed seat 10, and therefore the grinding pressure between the main grinding disc 19 and the auxiliary grinding disc 20 is increased and the grinding shearing range is shortened, the shearing of large-particle materials between the main grinding disc 19 and the auxiliary grinding disc 20 is realized, meanwhile, the materials are more smooth when passing through the side walls of the main grinding disc 19 and the fixed grinding disc 18 through extrusion, and the phenomenon that the materials are blocked between the main grinding disc 19 and the fixed grinding disc 18 is reduced;

material blockage at the top of feed box 16: when the grinding wheel works, because the materials are gathered at the top of the feeding box 16 and do not slide down to the auxiliary grinding disc 20, because the materials between the auxiliary grinding disc 20 and the main grinding disc 19 are continuously reduced during grinding, the load generated between the main grinding disc 19 and the auxiliary grinding disc 20 is gradually reduced, the load of the driving motor 2 is reduced, the rotating speed of the driving motor is increased, meanwhile, when the rotating speed of the driving shaft 3 is increased, the driving gear 4 drives the driven gear 11 to synchronously increase the rotating speed of the fixed seat 10, so that the movable magnetic block 15 is influenced by the outward throwing force and slides outward along the movable groove on the fixed seat 10, the relative distance between the movable magnetic block 15 and the floating magnetic block 14 is shortened, and the movable magnetic block 15 pushes the floating magnetic block 14 to move upward under the influence of the repulsive force between the floating magnetic block 14 and the movable magnetic block 15, and then the floating block 13 drives the transmission shaft 12 to move upwards through the floating magnetic block 14, the floating block 13 pushes the auxiliary grinding disc 20 to enable the material stirring block 21 to move upwards and to contact the blocking position through the material stirring block 21, the material is stirred continuously by the material stirring block 21, so that the material falls, after the material falls, the load of the driving motor 2 is increased again, the rotating speed of the driving shaft 3 is reduced, the movable magnetic block 15 slides to the bottom of the fixed seat 10 under the pressure of the floating magnetic block 14 and the gravity of the movable magnetic block, the grinding and shearing work is carried out again, and finally, the ground material is discharged from the discharge cylinder 22.
