Description

Technical Field

[0001] This utility model relates to the field of pigment production technology, and in particular to a sieving device for solid powder pigment production. Background Technology

[0002] In the production of solid powder pigments, sieving is a crucial step to ensure product quality and uniform particle size. High-quality sieving equipment not only improves pigment production efficiency but also plays a decisive role in the quality of the final product. With the continuous development of the pigment industry, higher demands are being placed on sieving equipment in terms of stability, ease of cleaning, and maintenance efficiency.

[0003] Currently, most solid powder pigment sieving equipment on the market adopts a simple vibrating sieving principle, relying on a motor to drive the screen body to vibrate, allowing the powder to be sieved on the screen surface. These devices use a fixed screen structure and vibration to allow powder that meets the particle size requirements to pass through the screen, achieving the separation of coarse and fine materials.

[0004] However, in actual use, these conventional screening equipment are prone to screen clogging due to the characteristics of solid powder pigments. Once the screen is clogged, it not only reduces screening efficiency and hinders production, but also increases labor intensity and production costs due to frequent manual cleaning, making it difficult to meet the needs of pigment manufacturers for efficient and stable production. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a sieving device for the production of solid powder pigments, which aims to improve the problem of powder clogging the screen in the actual use of conventional sieving equipment due to the characteristics of solid powder pigments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solid powder pigment production sieving device, comprising a base, a buffer spring fixedly connected to the upper surface of the base, a housing fixedly connected to the upper surface of the buffer spring, a top cover fixedly connected to the upper surface of the housing, a feed pipe fixedly connected to the upper surface of the top cover, a sieving plate slidably connected to the inner wall of the housing, and a cleaning component provided on the upper surface of the sieving plate;

[0007] The cleaning assembly includes a cleaning brush, the lower surface of which is attached to the upper surface of a screening plate. A sliding rod is fixedly connected to the upper surface of the cleaning brush. A second fixing plate is slidably connected to the outer wall of the cleaning brush. A first locking block is fixedly connected to the outer wall of the second fixing plate. A first spring is sleeved on the outer wall of the sliding rod. A first connecting rod is fixedly connected to the upper surface of the second fixing plate. A motor is fixedly connected to the upper surface of the top cover. The output end of the motor is fixedly connected to the top of the first connecting rod.

[0008] Furthermore, a slag discharge pipe is fixedly connected to the outer wall of the outer shell, a fixing plate is fixedly connected to the outer wall of the outer shell, a feeding pipe is fixedly connected to the outer wall of the outer shell, and a replacement component is provided on the inner wall of the fixing plate.

[0009] Furthermore, the replacement component includes a second locking block, the outer wall of which is slidably connected to the inner wall of a first fixing plate, a second connecting rod fixedly connected to the outer wall of the second locking block, a pressing block fixedly connected to the outer wall of the second connecting rod, a second spring fixedly connected to the outer wall of the pressing block, a sliding plate slidably connected to the inner wall of the first fixing plate, and the inner wall of the sliding plate fixedly connected to the outer wall of the screening plate.

[0010] Furthermore, one end of the spring is fixedly connected to the upper surface of the cleaning brush, and the other end of the spring is fixedly connected to the inner wall of the fixing plate.

[0011] Furthermore, the outer wall of the sliding rod is slidably connected to the inner wall of the second fixed plate, and the sliding rod is used to guide the cleaning brush.

[0012] Furthermore, the cleaning brush is disposed inside the housing and is used to scrape the material from the screening plate.

[0013] Furthermore, the outer wall of the second connecting rod is slidably connected to the inner wall of the first fixed plate, and the second connecting rod is used to drive the second locking block to move.

[0014] Furthermore, the outer wall of the first locking block is slidably connected to the inner wall of the outer shell, and the first locking block is used to limit the position of the second fixing plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the cleaning component is driven by a motor, and the cleaning brush is rotated to scrape the material. The cleaning brush is tightly attached to the screening plate by the elastic force of a spring, which effectively solves the problem of powder clogging the screening plate during the screening process. This not only greatly improves the scraping efficiency, but also ensures the stability of the scraping process by the limiting position of the locking block on the inner wall of the outer shell, thus ensuring the continuous and efficient operation of the screening work.

[0017] 2. In this utility model, pressing the pressing block inward causes the connecting rod two to move synchronously, causing the locking block two to slide along the inner wall of the fixed plate one, thereby disengaging from the inside of the sliding plate and releasing the fixation of the sliding plate. This achieves quick disassembly and installation of the screening plate, greatly reducing the difficulty of replacing the screening plate, shortening the equipment downtime for maintenance, and significantly improving the overall efficiency of the equipment.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a solid powder pigment production screening device, including a base 1, a buffer spring 2 fixedly connected to the upper surface of the base 1, a housing 14 fixedly connected to the upper surface of the buffer spring 2, a top cover 3 fixedly connected to the upper surface of the housing 14, and a feed pipe 6 fixedly connected to the upper surface of the top cover 3, which is responsible for accurately conveying the solid powder pigment to be screened into the interior of the housing 14, providing a material input channel for the screening process. A screening plate 15 is slidably connected to the inner wall of the housing 14, which screens the solid powder pigment through high-frequency vibration. A cleaning component is provided on the upper surface of the screening plate 15.

[0025] The cleaning assembly includes a cleaning brush 11, which scrapes material from the surface of the screening plate 15 by rotating to prevent clogging and ensure screening efficiency. The lower surface of the cleaning brush 11 is attached to the upper surface of the screening plate 15. A sliding rod 13 is fixedly connected to the upper surface of the cleaning brush 11, and a fixing plate 9 is slidably connected to the outer wall of the cleaning brush 11 to provide mounting support. Driven by the motor 7 and the connecting rod 8, the cleaning brush 11 performs a circular motion, scraping material from the screening plate 15. A locking block 10 is fixedly connected to the outer wall of the fixing plate 9, and the outer wall rotates along the inner wall of the outer casing 14 to restrict the fixing plate 9. The movement trajectory enhances the stability of the cleaning brush 11 in scraping material. A spring 12 is sleeved on the outer wall of the sliding rod 13. With its own elasticity, the cleaning brush 11 is always in close contact with the sieve plate 15, improving the scraping efficiency. A connecting rod 8 is fixedly connected to the upper surface of the fixed plate 2 9, connecting the output end of the motor 7 to the fixed plate 2 9, and transmitting the rotational power of the motor 7 to the fixed plate 2 9. A motor 7 is fixedly connected to the upper surface of the top cover 3. The fixed plate 2 9 is driven to make a circular motion around the sieve plate 15 through the connecting rod 18, thereby driving the cleaning brush 11 to rotate and scrape material. The output end of the motor 7 is fixedly connected to the top of the connecting rod 18.

[0026] Specifically, the solid powder pigment to be screened is first conveyed into the internal space of the outer shell 14 through the feed pipe 6. Then, the pre-configured vibration motor inside the equipment is started. The vibration force generated by the vibration motor will drive the screening plate 15 to vibrate at high frequency. During the screening process, due to the large amount of pigment powder, the screening plate 15 is prone to blockage. At this time, the motor 7 is started. The output end of the motor 7 drives the connecting rod 8 to rotate synchronously, thereby driving the fixed plate 9 to move around the screening plate 15 in a circular motion. The cleaning brush 11 fixed below the fixed plate 9 also rotates accordingly to scrape the surface of the screening plate 15. During this process, the spring 12 continuously pushes the cleaning brush 11 with its own elasticity, keeping it in close contact with the screening plate 15, which greatly improves the scraping efficiency. At the same time, the outer wall of the clamping block 10 rotates along the inner wall of the outer shell 14, effectively restricting the movement trajectory of the fixed plate 9, making the cleaning brush 11 more stable during the scraping process.

[0027] Reference Figure 3A slag discharge pipe 21 is fixedly connected to the outer wall of the outer casing 14. A fixing plate 5 is fixedly connected to the outer wall of the outer casing 14. A feed pipe 4 is fixedly connected to the outer wall of the outer casing 14. A replacement component is provided on the inner wall of the fixing plate 5. The replacement component includes a second locking block 17, which cooperates with the sliding plate 16 to fix and unlock the screening plate 15, facilitating the replacement of the screening plate 15. The outer wall of the second locking block 17 is slidably connected to the inner wall of the fixing plate 5. A second connecting rod 20 is fixedly connected to the outer wall of the second locking block 17. The connecting rod 20 connects the pressing block 18 and the locking block 17, transmitting the moving force of the pressing block 18 and driving the locking block 17 to move. The pressing block 18 is fixedly connected to the outer wall of the connecting rod 20. The operator presses the pressing block 18 to drive the connecting rod 20 to move, thereby separating or engaging the locking block 17 with the sliding plate 16. The pressing block 18 is fixedly connected to the outer wall of the spring 19. When the screening plate 15 is installed, the spring force causes the locking block 17 to engage inside the sliding plate 16, fixing the screening plate. 15. When the screening plate 15 is disassembled, it is deformed by the pressing block 18, causing the second locking block 17 to disengage from the sliding plate 16. The inner wall of the first fixing plate 5 is slidably connected to the sliding plate 16, which is fixedly connected to the screening plate 15. With the cooperation of the second locking block 17, the screening plate 15 can be quickly installed and disassembled. The inner wall of the sliding plate 16 is fixedly connected to the outer wall of the screening plate 15. One end of the first spring 12 is fixedly connected to the upper surface of the cleaning brush 11, and the other end of the first spring 12 is fixedly connected to the inner wall of the second fixing plate 9. The outer wall of the sliding rod 13 is slidably connected to the inner wall of the second fixing plate 9. The sliding rod 13 is used to guide the cleaning brush 11. The cleaning brush 11 is set inside the outer shell 14 and is used to scrape the screening plate 15. The outer wall of the second connecting rod 20 is slidably connected to the inner wall of the first fixing plate 5. The second connecting rod 20 is used to drive the second locking block 17 to move. The outer wall of the first locking block 10 is slidably connected to the inner wall of the outer shell 14. The first locking block 10 is used to limit the position of the second fixing plate 9.

[0028] Specifically, the operator presses the pressing block 18 inward, causing the connecting rod 20, which is fixedly connected to it, to move synchronously. This causes the spring 19 to undergo elastic deformation under pressure, and the locking block 17 disengages from the sliding plate 16, thus releasing the sliding plate 16 from its fixed state. Then, by pulling the sliding plate 16 outward, the worn screening plate 15 can be removed from the equipment for replacement. When installing the new screening plate 15, the operator pushes the sliding plate 16 to move the screening plate 15 smoothly into the outer casing 14. Then, the pressing block 18 is released, and the spring 19 returns to its elastic deformation. With its elastic force, the locking block 17 is engaged with the sliding plate 16, completing the fixation of the new screening plate 15 and successfully achieving the rapid replacement of the screening plate 15.

[0029] Working principle: When the screening equipment is needed, the powder is first fed into the inside of the outer shell 14 through the feed pipe 6. Then, the vibration motor inside the equipment is started to cooperate with the screening plate 15 for screening. During the screening process, too much powder can easily cause the screening plate 15 to become clogged. The starting motor 7 drives the fixed plate 9 to rotate the cleaning brush 11 to scrape the material from the screening plate 15. During this process, the elastic force of the spring 12 can push the cleaning brush 11 to fit tightly against the screening plate 15, thereby improving the scraping efficiency. The outer wall of the clamping block 10 rotates along the inner wall of the outer shell 14, making the scraping of the cleaning brush 11 more stable.

[0030] In addition, the screening plate 15 is prone to wear during long-term use and needs to be replaced. By pressing the pressing block 18 inward, the spring 19 is compressed, causing the locking block 17 to disengage from the sliding plate 16 and release the sliding plate 16. Then, by pulling out the sliding plate 16, the screening plate 15 can be replaced. When installing the screening plate 15, after pushing the sliding plate 16 to move the screening plate 15 into the housing 14, the pressing block 18 is released. The elastic force of the spring 19 can cause the locking block 17 to engage with the sliding plate 16 and be fixed, thus achieving the effect of quick replacement of the screening plate 15.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
