Description

Technical Field

[0001] This utility model relates to the field of powdering equipment, and in particular to a powdering equipment for tablecloths. Background Technology

[0002] Powder spreading equipment is a device that enables the uniform spreading of powdered materials. It is suitable for quantitative or qualitative spreading of materials in specific areas in scenarios such as agricultural planting, food processing, and building decoration. It is especially suitable for places where the working area is relatively concentrated and powder spreading tasks need to be completed at a high frequency. It can meet the basic requirements for powder material spreading efficiency and coverage in different scenarios.

[0003] Existing tablecloth powdering equipment typically involves first pouring the corresponding powder material into the equipment's powder storage bin according to the tablecloth material and the desired treatment effect. The equipment then targets the area of ​​the tablecloth to be treated, using its own powder dispensing structure to evenly cover the tablecloth surface with powder. Once the equipment is started, it achieves automated powdering operation.

[0004] Existing tablecloth powdering equipment has significant drawbacks in daily operation. Firstly, when the powder stored inside the equipment becomes damp due to environmental humidity, it easily clumps together. These clumps can easily get stuck in the powdering channel, causing blockages and forcing the powdering operation to stop, thus affecting overall work efficiency. Secondly, most existing equipment uses a fixed installation method for the powdering structure, with relatively fixed connections between components. When the powdering structure malfunctions and requires repair, workers must disassemble multiple fixed components to access the faulty part, which is not only cumbersome but also time-consuming, resulting in a complex and inefficient repair process. Therefore, this paper proposes a new tablecloth powdering device to solve these problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a powder-spreading device for tablecloths, aiming to improve the problems in the prior art where the powder clumps due to moisture, causing blockage of the powder-spreading structure and making the installation and maintenance of the powder-spreading structure complicated.

A knob 12 is threadedly connected to the outer wall of the mounting plate 3, adjusting the position of the connecting block 11 by rotating the knob 12, thereby changing the distance between the auxiliary roller 9 and the active roller 8, thus adjusting the pulverizing effect of the agglomerated powder.

[0024] Reference Figures 2-4A connecting block 11 is threaded onto the outer wall of the end of the knob 12. The connecting block 11 is used to install and fix the auxiliary roller 9 and the scraper 23. The auxiliary roller 9 is rotatably connected to its inner wall. The auxiliary roller 9 cooperates with the active roller 8 to crush and pulverize the agglomerated powder, and realizes the conveying and spreading of the powder. The auxiliary roller 9 meshes with the gear 10 on the mounting plate 3 through a fixedly connected gear 10, and is also connected to the active roller 8 through the gear 10 on the mounting plate 3. The scraper 23 is inserted into the inner wall of the connecting block 11. The scraper 23 is used to scrape off the powder remaining on the surface of the active roller 8 and the auxiliary roller 9. The top outer wall of the scraper 23 is in contact with the bottom outer wall of the active roller 8 and the auxiliary roller 9. The outer wall of the mounting plate 3 is provided with a mounting groove 16, which provides space for the slider 13 to move and be installed. The slider 13 is inserted into its inner wall and can move along the mounting groove 16 to adjust the position of the screen 15. The inner wall of the slider 13 is rotatably connected to a conveying shaft 14, which is used to filter the powder evenly from the screen 15. The bottom outer wall of the slider 13 is fixedly connected to the screen 15, which is used to break up the clumps of powder and ensure that the powder is evenly spread. The top outer wall of the mounting plate 3 is fixedly connected to a powder hopper 4, which is used to store the powder to be spread. The outer wall of the mounting plate 3 is fixedly connected to a shell 5 by bolts, which is used to protect the transmission structure.

[0025] Reference Figures 3-5 The inner wall of the mounting frame 1 is fixedly connected to a fixing block 21, which is used to install and fix the spring 20 and the guide rod 19. The outer wall of the fixing block 21 is fixedly connected to the spring 20, which provides elastic force to keep the mounting block 18 stable and has a certain buffering capacity. The inner wall of the fixing block 21 is inserted with the guide rod 19, which is used to limit the movement direction of the mounting block 18 and ensure its sliding stability. The end of the guide rod 19 is fixedly connected to the outer wall of the mounting block 18. The inner wall of the mounting frame 1 is slidably connected to the mounting block 18, which is used to install and fix the transmission roller 17.

The motor 2 at the top of the frame provides power after starting. The motor 2 transmits power through the transmission belt 6 connected to the output end. At the same time, the transmission belt 6 drives the transmission wheel 7 to achieve power steering and transmission. The gear 10 installed on the mounting plate 3 realizes the meshing transmission between components. Under the power drive, the active roller 8 is connected to the auxiliary roller 9 through the gear 10, driving the auxiliary roller 9 to rotate. If it is necessary to adjust the crushing effect of the agglomerated powder, the knob 12 can be rotated to change the position of the connecting block 11, thereby adjusting the distance between the auxiliary roller 9 and the active roller 8. The auxiliary roller 9 and the active roller 8 cooperate to crush and convey the agglomerated powder falling from the powder hopper 4. The scraper 23 on the connecting block 11 scrapes off the residual powder on the surface of the active roller 8 and the auxiliary roller 9. The crushed powder falls to the slider 13. The slider 13 can move along the mounting groove 16 of the mounting plate 3 to adjust the position of the screen 15. The conveying shaft 14 inside the slider 13 filters the powder evenly from the screen 15. The screen 15 further crushes the residual clumps of powder to ensure even spreading. At the same time, on the fixing block 21 on the inner wall of the mounting frame 1, the spring 20 provides elastic force and the guide rod 19 restricts the direction of movement, so that the mounting block 18 remains stable and can be buffered. The transmission roller 17 on the mounting block 18 drives the transmission table cloth 22 to move, realizing continuous powder spreading operation. The outer shell 5 on the outer wall of the mounting plate 3 protects the internal transmission structure of the equipment.
