Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel production technology, and in particular relates to a vibrating screening device for raw materials in grinding wheel production. Background Technology

[0002] Zirconium corundum has good resistance to molten metal erosion. As an advanced abrasive, it can be used to manufacture high-performance fiber-reinforced grinding wheels. Generally, zirconia corundum needs to be screened before processing fiber-reinforced resin thin-film grinding wheels in order to improve the quality of the grinding wheel.

[0003] When screening raw materials for grinding wheels, a vibrating screening device is required. Since the material tends to concentrate on the top of the screen plate during feeding, the material cannot fully contact the screen plate in a short time, leaving room for improvement in screening efficiency. Therefore, a vibrating screening device for raw materials in grinding wheel production is needed to disperse the material concentrated on the top of the screen plate, so that the material is evenly distributed when fed onto the top of the screen plate, thereby improving the efficiency of the vibrating screening device in screening raw materials. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating screening device for raw materials in grinding wheel production, which disperses the raw materials gathered at the top of the screen plate, so that the raw materials are evenly distributed when they are fed onto the top of the screen plate, thereby improving the efficiency of the vibrating screening device in screening raw materials and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A vibrating screening device for raw materials in grinding wheel production includes a vibrating frame: a screen plate is installed on the inner wall of the vibrating frame and a horizontal plate is fixedly connected thereto; a rotating column is rotatably connected to the top of the horizontal plate; a U-shaped plate and a groove plate are fixedly connected to the surface of the rotating column; a motor is fixedly installed on the top of the horizontal plate; a support rod is fixedly connected to the output shaft of the motor through a flange; a slider is rotatably connected to the surface of the support rod through a rotating shaft; a sliding groove, a locking block, and a rectangular block are provided on the top of the horizontal plate; a dial shaft is fixedly connected to the top of the rectangular block; and rake teeth are fixedly connected to the surface of the rectangular block.

[0006] Preferably, the slider is located in the inner cavity of the groove plate and is slidably connected to the inner wall of the groove plate.

[0007] Preferably, the slide groove is fixedly connected to the horizontal plate, and the locking block is slidably connected to the slide groove and fixedly connected to the rectangular block.

[0008] Preferably, the top end of the dial shaft extends into the inner cavity of the U-shaped plate, and a rotating sleeve is rotatably connected to the surface of the dial shaft, the rotating sleeve being in contact with the inner wall of the U-shaped plate.

[0009] Preferably, the bottom of the rake teeth fits into the top of the sieve plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a grooved plate to drive a rotating column to rotate back and forth, which in turn drives a rectangular block to move back and forth via a U-shaped plate and a rotating shaft. The rectangular block then drives the rake teeth to distribute the raw material on the top of the screen plate, thereby spreading out the raw material gathered on the top of the screen plate and ensuring that the raw material is evenly distributed when it is fed onto the top of the screen plate. This improves the efficiency of the vibrating screening device in screening raw materials.

[0012] 2. By using a rotating sleeve, this utility model protects the surface of the dial shaft, preventing it from wearing out too quickly when it comes into direct contact with the inner wall of the U-shaped plate, thereby improving the service life of the dial shaft. Attached Figure Description

A screen plate 2 is installed on the inner wall of the vibrating frame 1 and a horizontal plate 3 is fixedly connected thereto. A rotating column 4 is rotatably connected to the top of the horizontal plate 3. A U-shaped plate 5 and a groove plate 6 are fixedly connected to the surface of the rotating column 4.

[0023] Example 2:

[0024] Figure 1-4 This invention illustrates a vibrating sieving device for raw materials used in grinding wheel production, comprising a vibrating frame 1; a sieve plate 2 is mounted on the inner wall of the vibrating frame 1 and a horizontal plate 3 is fixedly connected thereto; a rotating column 4 is rotatably connected to the top of the horizontal plate 3; a U-shaped plate 5 and a groove plate 6 are fixedly connected to the surface of the rotating column 4; a motor 7 is fixedly mounted on the top of the horizontal plate 3; a support rod 8 is fixedly connected to the output shaft of the motor 7 via a flange; a slider 9 is rotatably connected to the surface of the support rod 8 via a rotating shaft; and a sliding groove 10, a locking block 11, and a rectangular block 12 are provided on the top of the horizontal plate 3. A rotary shaft 13 is fixedly connected to the top of the rectangular block 12. The top end of the rotary shaft 13 extends into the inner cavity of the U-shaped plate 5. A rotating sleeve 14 is rotatably connected to the surface of the rotary shaft 13. The rotating sleeve 14 fits against the inner wall of the U-shaped plate 5. The rotating sleeve 14 protects the surface of the rotary shaft 13, preventing the rotary shaft 13 from wearing out too quickly when it comes into direct contact with the inner wall of the U-shaped plate 5, thereby improving the service life of the rotary shaft 13. A rake tooth 15 is fixedly connected to the surface of the rectangular block 12. The bottom of the rake tooth 15 fits against the top of the sieve plate 2.

[0025] Working Principle: When using this invention, the user pours the raw material into the vibrating frame 1. At this time, the vibrating frame 1 drives the screen plate 2 to screen the raw material. Simultaneously, the motor 7 is turned on to drive the support rod 8 to rotate. The support rod 8 drives the rotating column 4 to rotate back and forth through the slider 9 and the groove plate 6. Then, the rotating column 4 drives the rotating shaft 13 through the U-shaped plate 5 to move the rectangular block 12 back and forth. During this process, the movement of the rectangular block 12 is limited by the cooperation of the sliding groove 10 and the locking block 11, ensuring the stability of the position of the rectangular block 12 during movement. Then, the rectangular block 12 drives the rake teeth 15 to distribute the raw material on the top of the screen plate 2, realizing the spreading of the raw material gathered on the top of the screen plate, so that the raw material is evenly distributed when it is put on the top of the screen plate, thereby improving the efficiency of the vibrating screening device in screening raw materials.

[0026] In summary, this vibrating screening device for raw materials used in grinding wheel production drives the rotating column 4 to reciprocate through the groove plate 6. The rotating column 4, through the U-shaped plate 5, moves the rotating shaft 13 to drive the rectangular block 12 to reciprocate. The rectangular block 12 then drives the rake teeth 15 to distribute the raw material on the top of the screen plate 2. This achieves the purpose of spreading out the raw material gathered on the top of the screen plate, so that the raw material is evenly distributed when it is put into the top of the screen plate, thereby improving the efficiency of the vibrating screening device in screening raw materials.
