Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, and in particular to an automated powder conveying device. Background Technology

[0002] The powder conveying system achieves the purpose of powder conveying through vacuum suction. The system can automatically convey various materials to the hopper of the processing equipment, solving the dust problem during feeding and reducing the labor intensity of workers.

[0003] Existing powder conveying systems use negative pressure to transport powder from the raw material bin to the processing equipment. During the conveying process, the powder needs to be screened by screening equipment to ensure the uniformity of the conveyed powder particles. However, the existing screening mechanism can only screen by particle size and cannot effectively crush agglomerated powder. During the long-term powder conveying process, the accumulated powder clumps will gradually block the screening mechanism, affecting the use of the equipment and requiring frequent cleaning and replacement, thus reducing production efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an automated powder conveying device to solve the problem that the screening mechanism cannot effectively remove powder clumps and is prone to clogging.

[0005] To achieve the above objectives, this utility model provides an automated powder conveying device, including a storage bin and a powder collection bin. A negative pressure fan is installed on one side of the powder collection bin. The storage bin and the powder collection bin are connected by a conveying pipeline. A processing bin is installed on the conveying pipeline. The processing bin is equipped with a sieving mechanism to sieve and process the conveyed powder. A drying mechanism is installed on the inner side wall of the processing bin to dry the conveyed powder.

[0006] A further improvement is that the screening and processing mechanism includes a screen frame, which is installed inside the processing box. A screen is installed in the middle of the screen frame. A support is installed inside the processing box. A motor is installed on one side of the support, and a scraper is rotatably installed on the other side of the support. The output end of the motor is connected to the scraper, and the scraper is set to fit the screen.

[0007] A further improvement is that a grinding plate is set in the middle of the screen frame, the grinding plate and the screen are spaced apart, the scraper is arc-shaped, and a pressing plate is set on the side of the scraper, and the pressing plate is inclined.

[0008] A further improvement is that a vibrating rod is installed on the motor output end, and a striking block is set at the end of the vibrating rod. Multiple protrusions are equidistantly arranged around the side of the screen frame, and both the protrusions and the striking blocks are curved structures.

[0009] A further improvement is that the drying mechanism includes a heating plate, which is arranged around the inner wall of the processing chamber.

[0010] A further improvement is that the negative pressure fan and the powder collection box are connected by a blower pipe, and a filter is installed at the connection between the powder collection box and the blower pipe.

[0011] The beneficial effects of this invention are as follows: By installing a negative pressure fan to create negative pressure inside the powder collection box, the powder is conveyed through the conveying pipeline. The sealed conveying system reduces powder dispersion and airborne particles in the workshop, improving the working environment and lowering the risk of dust exposure for operators, thus protecting employee health. Automated operation reduces manual intervention and lowers labor costs. Furthermore, precise control of the conveying process reduces powder waste, improves raw material utilization, and further reduces production costs.

[0012] The conveyed powder is screened by a screening mechanism. A scraper removes powder clumps from the screen surface, reducing clogging. The scraped powder clumps move along the scraper to the grinding plate, where they are crushed by the action of the pressure plate and grinding plate, further reducing powder clump aggregation. A vibrating rod, driven by a motor, causes the striking block to contact the protruding block, thus striking the screening frame and reducing powder adhesion to the screen surface, effectively preventing screen clogging.

The output end of the motor 9 is connected to the scraper 10. The scraper 10 is set to fit against the screen 7. The motor 9 drives the scraper 10 to rotate, and the scraper 10 scrapes off the powder clumps accumulated on the screen 7. A grinding plate 11 is provided in the middle of the screen frame 6. The grinding plate 11 and the screen 7 are spaced apart. The scraper 10 is arc-shaped. A pressing plate 12 is provided on the side of the scraper 10. The pressing plate 12 is inclined. As the scraper 10 rotates, the powder agglomerates gather and move along the side of the scraper 10 toward the grinding plate 11. The powder agglomerates gradually move onto the grinding plate 11. The cylinder is gradually crushed by the pressing plate 12, thereby reducing the presence of powder agglomerates and reducing the generation of blockages.
