Automatic conveying device for silicon carbide micro-powder

Abstract

This utility model discloses an automatic conveying device for silicon carbide micro powder, including two mounting frames. Two rotating shafts are rotatably connected between the two mounting frames. A transmission mounting roller is fixedly connected to the outer surface of each rotating shaft, and a transmission belt drives the two transmission mounting rollers. When the drive cylinder is activated, the piston end of the drive cylinder moves the first connecting shaft, which in turn moves the movable feeding shell, causing the movable feeding shell to move closer to the transmission belt. The movable feeding shell is positioned below the conveying box. As the conveying box continues to move, the powder material inside the conveying box falls onto the movable and fixed feeding shells, and then through the fixed feeding shell into the feed hopper of the screening device. This method is time-saving, labor-saving, and safe and convenient to operate.

Description

[0001] This utility model relates to the field of silicon carbide micro powder production technology, and in particular to an automatic conveying device for silicon carbide micro powder. Background Technology

[0002] Silicon carbide micron powder refers to micron-sized silicon carbide powder that has been ultrafinely pulverized and classified using industrial grinding equipment. Since silicon carbide micron powder is primarily used in the abrasive industry, there are specific requirements for its classification; large particles must not be present, as their presence would severely impact the quality of abrasive production.

[0003] In the production process of silicon carbide micro powder, it is necessary to perform screening. The silicon carbide micro powder raw material is fed into a screening device for screening. In the existing technology, the feeding method is often to manually add the powder raw material to the feed hopper of the screening device multiple times. This method is time-consuming and labor-intensive. Moreover, adding the powder raw material to a high place poses certain safety hazards. Utility Model Content

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with the existing technology, this automatic silicon carbide micro powder conveying device starts the drive cylinder, and the piston end of the drive cylinder moves the first connecting shaft. The connecting mounting column moves the movable feeding shell, causing the movable feeding shell to move closer to the transmission belt. The movable feeding shell is located below the conveying box. The conveying box continues to move, causing the powder raw material inside the conveying box to fall onto the movable feeding shell and the fixed feeding shell. It then falls into the feed hopper of the screening device through the fixed feeding shell. This saves time and effort and is safe and convenient to operate.

[0020] 2. Compared with the existing technology, the automatic conveying device for silicon carbide micro powder starts the second servo motor. The output shaft of the second servo motor rotates the second connecting shaft, and the second connecting shaft rotates the striking cam. This causes the striking cam to continuously strike the fixed feeding shell, which speeds up the discharge of powder raw materials on the fixed feeding shell and reduces the residue of powder raw materials.

[0031] Working principle:

[0032] In use, first move the device to the screening device, positioning the fixed feeding housing 9 above the screening device's feed hopper. Add the silicon carbide micro powder raw material to the conveying box 6. Start the first servo motor 7. The output shaft of the first servo motor 7 rotates the first pulley, causing one of the rotating shafts to rotate the transmission mounting roller 4. The two transmission mounting rollers 4 move the transmission belt 5, which in turn moves the conveying box 6. When the conveying box 6 containing the powder raw material rotates to a high position, start the drive cylinder 14. The drive cylinder 14 then... The plug moves with the first connecting shaft, the first connecting shaft moves with the rectangular connecting block 13, the rectangular connecting block 13 moves with the connecting mounting column 12, and the connecting mounting column 12 moves with the movable feeding shell 10, causing the movable feeding shell 10 to move closer to the transmission belt 5. The movable feeding shell 10 is located below the conveying box 6. The conveying box 6 continues to move, causing the powder raw material inside the conveying box 6 to fall onto the movable feeding shell 10 and the fixed feeding shell 9, and then fall into the feed hopper of the screening device through the fixed feeding shell 9.

[0033] After the powder material inside the material conveying box 6 is poured out, the movable feeding shell 10 returns to its original position, making it easy for the empty material conveying box 6 to pass through.

[0034] The second servo motor 16 is started. The output shaft of the second servo motor 16 rotates the second connecting shaft, which in turn rotates the striking cam 17. This causes the striking cam 17 to continuously strike the fixed feeding housing 9, accelerating the discharge of powder raw materials from the fixed feeding housing 9 and reducing the residue of powder raw materials.
