Description
Technical Field
[0001] This utility model relates to the field of coating vibrating sieving technology, and in particular to a coating vibrating sieve for coating production. Background Technology
[0002] Paint is a material applied to the surface of an object, forming a solid film with protective, decorative, or special functions. It typically consists of film-forming substances, pigments, solvents, and additives. Film-forming substances are the key component of paint, determining the basic properties of the coating, such as adhesion, hardness, and weather resistance; common examples include resins and rubbers. Pigments give paint color and hiding power, resulting in an aesthetically pleasing appearance and enhancing the coating's durability. Solvents dissolve the film-forming substances and adjust the paint's viscosity for easier application; they evaporate during the drying process. Additives improve certain properties of the paint, such as leveling and drying speed. Paints are widely used in construction, automobiles, shipbuilding, furniture, and many other fields. They not only protect surfaces from environmental damage and extend their lifespan but also enhance aesthetics and meet diverse aesthetic and performance requirements.
[0003] A paint vibrating screen is a specialized device for screening paint. It utilizes vibration to cause the paint to vibrate at high frequency on a screen mesh, thus achieving screening and grading. The vibration causes the paint particles to continuously jump and tumble on the screen, preventing particle agglomeration and clogging, ensuring screen permeability and improving screening efficiency. Secondly, vibration allows particles of different sizes in the paint to be more accurately stratified according to size. Smaller particles pass through the screen faster, while larger particles are intercepted, achieving precise grading and ensuring uniform particle size distribution, thus improving paint quality and stability. Furthermore, vibration promotes uniform distribution of paint on the screen surface, preventing localized accumulation and making the screening process more uniform and efficient.
[0004] However, some existing paint vibrating screens cannot achieve efficient vibrating screening of paint. As a result, some larger particles cannot pass through the appropriate screen openings during the screening process, leading to low screening efficiency and an inability to effectively separate impurities from qualified paint. This seriously affects the overall efficiency and quality of paint production. Therefore, in order to address the above shortcomings, a paint vibrating screen for paint production is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a coating vibrating screen for coating production, which aims to improve the problem that some existing coating vibrating screens cannot achieve efficient vibration screening of coatings.

[0012] As a further description of the above technical solution:
[0013] A bevel gear one is fixedly connected to the outside of the drive shaft, a rotating shaft is rotatably connected to the inside of the fixed frame, a bevel gear two is fixedly connected to the outside of the rotating shaft, a scraper frame is fixedly connected to the bottom outside of the rotating shaft, and multiple scraper plates are fixedly connected to the top of the scraper frame.

[0024] This utility model has the following beneficial effects:
[0025] 1. In this invention, a motor drives the drive shaft and cam to rotate. The eccentricity of the cam causes it to intermittently press against the bottom of the second filter screen plate. Through the hinge between the second filter screen plate and the movable ball, the second filter screen plate is displaced and vibrates. This vibration not only acts on the second filter screen plate but is also transmitted through the connecting ring, the first filter screen plate, the fixed ring, and the support ring, driving the entire screening assembly to vibrate. Simultaneously, the cooperation of the sliding rod and the spring further enhances the vibration effect. The support ring quickly resets under the elastic force of the spring, enabling the screening assembly to continuously and efficiently screen the coating, greatly improving screening efficiency.
[0026] 2. In this invention, when the drive shaft rotates, it drives the first bevel gear to rotate. Through meshing with the second bevel gear, the drive shaft rotates, causing the scraper frame and scraper plate to perform circular motion. The scraper plate is externally slidably connected to the inside of the screening tank. During its circular motion, it scrapes the paint adhering to the inner wall of the screening tank, effectively preventing paint from accumulating on the inner wall, keeping the inner wall of the screening tank clean, and avoiding the impact of paint adhesion on subsequent screening work, thereby improving the overall screening efficiency and service life of the equipment.

[0033] 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.
[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a paint production vibrating screen, including a screening tank 1, which serves as the main container for the paint screening process. A drive assembly for providing power is located on the front side of the screening tank 1. The drive assembly includes a housing 2, the rear side of which is fixedly connected to the front side of the screening tank 1. A motor 3 is installed inside the housing 2, serving as the power source for the drive assembly. A drive shaft 4 is fixedly connected to the output end of the motor 3, and the drive shaft 4 rotates under the drive of the motor 3. A cam 5 is fixedly connected to the outside of the drive shaft 4. When the drive shaft 4 rotates under the drive of the motor 3, the cam 5 rotates with the drive shaft 4, and due to its eccentric characteristics, it intermittently squeezes the bottom of the filter screen plate 13. Multiple sliding rods 6 are slidably connected to the top of the screening tank 1, and each sliding rod 6 is fitted with a spring 7. When the filter screen plate vibrates, the sliding rods 6 displace along with the support ring 9, and under the action of the spring 7, they can quickly reset, enhancing the vibration effect. One end of the spring 7 is fixedly connected to the top side inside the screening tank 1, and the other end of the spring 7 is fixedly connected to the top of the support ring 9. During the vibration of the filter screen plate, the spring 7 will be compressed by the pressure transmitted from the sliding rod 6 and the support ring 9. When the pressure disappears, the spring 7 will quickly reset the support ring 9 by its own elasticity, thereby further improving the vibration effect and ensuring that the coating can be fully screened.
[0035] Reference Figures 2 to 3Each of the multiple sliding rods 6 has a limiting plate 8 fixedly connected to its top. The main function of the limiting plate 8 is to prevent the sliding rods 6 from detaching from the top of the screening tank 1 during movement. Support rings 9 are movably connected to the bottom of each of the multiple sliding rods 6, serving both support and connection functions. A fixing ring 10 is fixedly connected to the bottom of each support ring 9. The outside of the fixing ring 10 is slidably connected to the inside of the screening tank 1. A filter screen plate 11 is fixedly connected to the bottom of the fixing ring 10. During vibration, the filter screen plate 11 can perform preliminary screening of the coating, blocking larger particles of impurities above the screen plate, while smaller particles of coating pass through the screen holes to enter the next screening layer. A connecting ring 12 is fixedly connected to the bottom of the filter screen plate 11, and a filter screen plate 13 is fixedly connected to the bottom of the connecting ring 12. The diameters of the support ring 9, fixing ring 10, filter screen plate 11, connecting ring 12, and filter screen plate 13 are all slightly smaller than the diameter of the screening tank 1 to accommodate the screening action. The external sliding connection of filter screen plate 2 13 is to the inside of the screening tank 1. The screen hole size of filter screen plate 2 13 is different from that of filter screen plate 1 11, so as to achieve further fine screening of the coating.
[0036] Under the intermittent squeezing action of cam 5, filter screen plate 13 vibrates, further screening the coating material that has been initially screened by filter screen plate 11, allowing the qualified coating material to pass through the screen holes and enter the bottom of screening tank 1. Screening tank 1 is equipped with a protective assembly, which includes two support rods 14. The two support rods 14 are externally fixedly connected to the inside of screening tank 1, and the support rods 14 serve to support the fixed frame 15. The fixed frame 15 is fixedly connected to the adjacent side of the two support rods 14, and a connecting rod 18 is fixedly connected to the left side of the fixed frame 15. The connecting rod 18 is externally fixedly connected to the inside of screening tank 1. A movable ball 16 is fixedly connected to the top of the protective assembly. The outer top side of the movable ball 16 is hinged to the bottom of filter screen plate 13. The movable ball 16 allows filter screen plate 13 to flexibly change its angle and position when vibrated by the squeezing action of cam 5, ensuring the uniformity and efficiency of the vibration effect. A feed pipe 25 is fixedly connected to the top of the screening tank 1. The feed pipe 25 is the channel through which the coating enters the screening tank 1. A conical ring 26 is fixedly connected to the top of the feed pipe 25.
[0037] Reference Figures 2 to 4A bevel gear 17 is fixedly connected to the outside of the drive shaft 4. When the drive shaft 4 rotates, the bevel gear 17 rotates accordingly. A rotating shaft 19 is rotatably connected inside the fixed frame 15. A bevel gear 20 is fixedly connected to the outside of the rotating shaft 19. The bevel gear 17 and the bevel gear 20 are meshed together. A scraper frame 21 is fixedly connected to the bottom outside of the rotating shaft 19. Multiple scraper plates 22 are fixedly connected to the top of the scraper frame 21. Under the transmission action of the bevel gear 17 and the bevel gear 20, the rotating shaft 19 rotates, thereby driving the scraper frame 21 and the scraper plates 22 to perform circular motion. The scraping plate 22 is externally slidably connected to the inside of the screening tank 1. Driven by the rotating shaft 19, the scraping plate 22 performs a circular motion, scraping the paint adhering to the inner wall of the screening tank 1 to prevent paint accumulation, ensuring the cleanliness of the inner wall of the screening tank 1, and improving the screening efficiency and service life of the equipment. A discharge pipe 23 is fixedly connected to the bottom of the screening tank 1, serving as the channel for discharging the screened paint. A valve 24 is installed externally on the discharge pipe 23 to control the discharge volume and speed of the paint. Support legs 27 are fixedly connected to the four corners of the bottom of the screening tank 1.
[0038] Working Principle: When using this paint vibrating screen in paint production, simply pour the paint into the screening tank 1 through the conical ring 26 and the feed pipe 25. Then, start the motor 3. The motor 3 drives the drive shaft 4 and cam 5 to rotate. As the cam 5 rotates, the bottom of the filter screen plate 13 is intermittently squeezed by the cam 5. This displacement of the filter screen plate 13, caused by the hinge between the filter screen plate 13 and the movable ball 16, results in vibration of the filter screen plate 13. This vibration, in turn, causes displacement of the connecting ring 12, filter screen plate 11, fixed ring 10, and support ring 9, which in turn causes displacement of the sliding rod 6. This, in turn, causes the spring 7 to be subjected to... The force compresses, and the spring force of the spring 7 allows the support ring 9 to quickly return to its original position, thereby further improving the vibration effect. The coating can be effectively screened by the filter screen plate 11 and the filter screen plate 13. The screened coating will fall to the bottom of the screening tank 1. At this time, the rotation of the drive shaft 4 will drive the bevel gear 17 to rotate, which in turn drives the bevel gear 20 to rotate, which in turn drives the rotating shaft 19 to rotate. This will drive the scraper 21 and the scraper plate 22 to make a circular motion, which will scrape the coating adhering to the inner wall of the screening tank 1, thereby effectively preventing the coating from adhering to the inner wall of the screening tank 1. Finally, it can be discharged through the discharge pipe 23.
[0039] 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.
