Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for non-metallic mineral products. Background Art

[0002] Non-metallic mineral products are manufactured products made from raw materials with inherent properties of non-metallic minerals. They are of various types and properties and are widely used in national economic construction. The materials of non-metallic mineral products are as follows: lightweight building materials and thermal insulation and sound insulation materials (gypsum products, natural stone products, calcium silicate products, expanded perlite products, etc.), various refractory bricks and high-temperature insulation materials, sealing materials (cylinder gaskets, packings), friction materials (various brake pads, clutch plates), electrical insulation materials (mica products), filtration, adsorption, chemical catalytic materials, etc. At present, in the industrial production process, the original materials need to be ground and crushed, and the crushed particles are required to meet the required requirements.

[0003] After the non-metallic mineral products are crushed, they need to be ground by a grinder. When grinding with existing grinding equipment, the materials usually remain stationary on the material tray and are easily piled up during grinding, resulting in uneven grinding and reduced grinding efficiency. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The object is put into the bottom shell, and the push rod motor extends downward to drive the grinding mechanism to move downward. The servo motor rotates the grinding mechanism to rotate and grind the object in the bottom shell. The rotating grinding rod lifts the ground powder through the spiral groove, and cooperates with the baffle to block the top of the fixed ring, so that the lifted powder passes through the screen and falls into the collection box under the action of the rotating centrifugal force.

[0008] Preferably, a fixing frame is fixed to one end of the top of the bottom plate, and a push rod motor is installed on the top inner wall of the fixing frame.

[0009] The push rod motor is installed and fixed by a fixing bracket.

[0010] Preferably, a servo motor is fixed to the bottom end of the push rod motor, and the output shaft of the servo motor is connected and fixed to the top end of the rotating rod.

[0011] The height position of the grinding mechanism is adjusted by the extension and retraction of the push rod motor, and the grinding mechanism is rotated by the servo motor to complete the grinding operation.

[0012] Preferably, fixed blocks are fixed around the outer wall of the bottom shell at equal distances, and one end of the fixed block away from the bottom shell is connected and fixed to the inner wall of the collection box.

[0013] The placement mechanism is connected and fixed to the inner wall of the collection box through a connected fixing block.

[0014] Preferably, the bottom of the bottom shell and the bottom of the collection box do not contact each other, and the bottom of the collection box is plug-connected to the bottom plate through a hexagonal block.

[0015] A gap is left between the bottom shell and the collecting box to facilitate pouring out of the ground powder.

[0016] Preferably, a spiral groove is formed on the rod wall of the grinding rod, and the outer diameter of the grinding rod is smaller than the top inner diameter of the bottom shell.

[0017] The rotating grinding rod lifts the ground powder through the spiral groove, and the lifted powder falls into the collection box through the screen under the action of the rotating centrifugal force.

[0018] The beneficial effects of the utility model are:

[0019] By putting an object into the bottom shell, the push rod motor extends downward to drive the grinding mechanism to move downward, and the servo motor rotates the grinding mechanism to rotationally grind the object in the bottom shell. The rotating grinding rod lifts the ground powder through the spiral groove, and cooperates with the baffle to block the top of the fixed ring, so that the lifted powder falls into the collection box through the screen under the action of the rotating centrifugal force. This effectively solves the problem in the prior art that when grinding equipment is grinding, the material usually remains stationary on the material tray, and is easily piled up during grinding, resulting in uneven grinding and reduced grinding efficiency.
