Description

[0001] The invention belongs to the technical field of lever-type grinding mills, and in particular relates to a lever-type grinding mill and a grinding head processing method thereof. Background Art

[0002] A lever mill is a device that uses the lever principle to grind materials. It usually has a rotatable grinding head. Through a specific lever structure and transmission device, the grinding head extrude, rub and grind the material in a specific motion in the grinding chamber, thereby crushing the material into the required powder size. The lever structure can adjust the pressure and contact method between the grinding head and the inner wall of the grinding chamber to meet the grinding needs of different materials, reduce the wear of components to a certain extent, and improve the stability and service life of the equipment.

[0003] In the field of powder processing, the grinding mill is a vital equipment. During the feeding process of the grinding mill, the materials enter the grinding chamber in a concentrated manner, which is prone to uneven distribution and causes material accumulation in some areas, affecting the grinding effect and efficiency. In addition, the rigid contact between the grinding head and the inner wall of the grinding chamber will cause excessive wear of the components, surface peeling and other problems, reducing the service life and stability of the equipment. For this reason, it is necessary to provide a lever-type grinding mill and a grinding head processing method thereof, which adopts a spiral to lift the materials and evenly disperse the materials so that the materials enter the grinding chamber evenly, and adopts an elastic internal support structure to prevent the grinding head from being damaged by rigid contact with the inner wall of the grinding chamber, and is equipped with a quick adjustment structure to quickly adjust the circular motion radius of the grinding head. Summary of the invention

[0004] The purpose of the present invention is to provide a lever-type grinding mill and a grinding head processing method thereof, which adopts a spiral to lift materials and evenly disperse materials so that the materials enter the grinding chamber evenly, and adopts an elastic internal support structure to prevent the grinding head from being damaged by rigid contact with the inner wall of the grinding chamber. At the same time, it is equipped with a quick adjustment structure, which can quickly adjust the circular motion radius of the grinding head to solve the above-mentioned technical problems.

[0005] The technical solution of the present invention for solving the above technical problems is as follows: a lever-type grinding mill and a grinding head processing method thereof, which are applied to a lever-type grinding mill, the lever-type grinding mill comprises a grinding mill chamber and a stone ball grinding head: the top of the grinding mill chamber is rotatably connected with a swivel, the inner cavity of the swivel is provided with an adjusting component, the inner cavity of the stone ball grinding head is provided with an inner support component, the inner support component comprises an inner support sleeve fixedly connected to the inner cavity of the stone ball grinding head, the top and bottom of the surface of the inner support sleeve are welded with a fixing plate, a plurality of bolts are annularly distributed on the surface of the fixing plate, the bolts penetrate the fixing plate and are fixedly connected to the stone ball grinding head, the top and bottom of the stone ball grinding head are provided with a positioning plate, a plurality of threaded pull rods are annularly distributed between the two positioning plates, the top and bottom ends of the threaded pull rods are both penetrated to one side of the positioning plate and are threadedly connected with a nut, the inner wall of the inner support sleeve is annularly distributed with a plurality of dampers, one end of the damper The gear is connected to the gear of the gear train of the motor and the gear is connected to the gear of the gear train through the gear chain, and the gear is connected to the gear of the gear train by the gear train connected to the gear of the gear train.

[0006] The processing method of the lever type grinding mill and the grinding head thereof is as follows:

[0007] 1. The user first conveys the material into the inner cavity of the feed bin, and then turns on the second DC motor, which drives the spiral conveying rod to rotate. During the rotation, the spiral conveying rod spirally lifts the material in the inner cavity of the feed bin, so that the material passes through the inner cavities of the fixed conveying pipe and the telescopic conveying pipe and enters the inner cavity of the discharge pipe. At the same time, the third DC motor is turned on, and the third DC motor drives the turntable to rotate in the inner cavity of the material shielding cover through the driving rod. The material entering the inner cavity of the discharge pipe enters the inner cavity of the material shielding cover under the combined action of material extrusion and gravity, so that the material falls to the top of the turntable. Under the rotation of the turntable, the material is evenly dispersed to the periphery of the inner cavity of the lifting platform, so that the material falls evenly into the inner cavity of the grinding mill bin;

[0008] Second, the first DC motor is turned on at the same time, and the first DC motor drives the driving gear to rotate. Due to the meshing transmission of the driving gear and the stressed gear ring, the rotating ring rotates in the inner cavity of the grinding mill chamber. The rotating ring drives the inner support sleeve to perform circular motion in the inner cavity of the grinding mill chamber through the common transmission action of the inner support seat, the sliding pin and the lever, thereby making the stone ball mill perform circular motion in the inner cavity of the grinding mill chamber. At the same time, the universal coupling rotates accordingly and grinds the materials entering the inner cavity of the grinding mill chamber. During the circular motion of the stone ball mill, the damper expands and contracts, thereby squeezing the stone ball mill, thereby strengthening the force of the stone ball mill surface on the material, and avoiding the rigid contact between the stone ball mill and the inner wall of the grinding mill chamber, which causes the stone ball mill surface to fall off or excessively wear.

[0009] 3. The user can adjust the grinding force of the stone ball mill according to the grinding needs. When adjusting, the user turns on the electric telescopic rod, so that the electric telescopic rod pushes the lifting platform upward to move, and at the same time makes the telescopic material delivery pipe slide on the surface of the fixed material delivery pipe. After the material cover is separated from the inner cavity of the rotating ring, the user uses an electric sleeve to cover the right end of the threaded adjustment rod, so that the threaded adjustment rod rotates in the inner cavity of the fixed frame. The fixed frame drives the threaded seat to move during the rotation process, thereby changing the angle of the sliding pin and the lever, and finally changing the circular motion radius of the stone ball mill, so as to adjust the contact force between the surface of the stone ball mill and the inner wall of the mill chamber;

[0010] 4. Finally, the ground materials are at the bottom of the inner cavity of the mule mill. The materials that meet the processing requirements fall from the pores on the surface of the filter under the repeated rolling action of the stone ball mill head and are discharged into the inner cavity of the discharge bin. The materials that do not meet the processing requirements remain on the surface of the filter and continue to be ground.

The grinding machine (1) performs a circular motion in the inner cavity of the grinding machine bin (1), and the universal coupling (65) rotates accordingly, and grinds the material entering the inner cavity of the grinding machine bin (1). During the circular motion of the stone ball grinding head (2), the damper (57) expands and contracts, thereby squeezing the stone ball grinding head (2), thereby strengthening the force of the stone ball grinding head (2) on the material, and preventing the stone ball grinding head (2) from rigidly contacting the inner wall of the grinding machine bin (1), causing the surface of the stone ball grinding head (2) to fall off or excessively wear; 3. The user can adjust the grinding force of the stone ball mill (2) according to the grinding requirements. When adjusting, the user turns on the electric telescopic rod (92), so that the electric telescopic rod (92) pushes the lifting platform (91) upward to move, and at the same time makes the telescopic material delivery pipe (83) slide on the surface of the fixed material delivery pipe (81). After the material shielding cover (93) is separated from the inner cavity of the rotating ring (3), the user uses an electric sleeve to be sleeved on the right end of the threaded adjustment rod (43), so that the threaded adjustment rod (43) rotates in the inner cavity of the fixed frame (42). The fixed frame (42) drives the threaded seat (44) to move during the rotation process, thereby changing the angle of the sliding pin (46) and the lever (64), and finally changing the circular motion radius of the stone ball mill (2), thereby adjusting the contact force between the surface of the stone ball mill (2) and the inner wall of the grinding machine chamber (1); Fourth, the ground materials are at the bottom of the inner cavity of the mule mill bin (1). The materials that meet the processing requirements fall from the pores on the surface of the filter screen (66) under the rolling action of the stone ball mill head (2) and enter the inner cavity of the discharge bin (7) for discharge. The materials that do not meet the processing requirements are retained on the surface of the filter screen (66) and continue to be ground.
