Description

Technical Field

[0001] The invention relates to the technical field of paint raw material production, and in particular to a paint filtering device in paint production and processing. Background Art

[0002] Paint filter is a kind of filtering equipment specially designed for use in the paint production and processing. Its main function is to remove solid impurities, particulate matter and possible sediments in the paint, thereby ensuring the purity and uniformity of the paint. This device is widely used in paint production, coating lines, ink manufacturing and other fields.

[0003] In the prior art, a Chinese patent document with publication number CN221230101U proposes an impurity filtering device for paint raw material production, including a processing box, a top hopper fixedly connected to the left side of the processing box, a filtering mechanism arranged inside the processing box, a filtering frame arranged on one side of the filtering mechanism, a collecting mechanism arranged on the right side of the filtering frame, the top hopper fixedly connected to the left side of the filtering frame, and the filtering mechanism including a pushing component. Although the impurity filtering device for paint raw material production can improve the smoothness of the paint flow filtering process when the pushing frame reciprocates left and right through the filtering mechanism, there will be no accumulation at the bottom of the filtering frame, and good filtering quality can be achieved. The paint raw materials can be further processed to enhance the practicality of the device, but in actual use, the liquid inlet of the paint filter device is fixed at a specific position, which makes it easy for solid impurities in the paint to deposit and block the tiny holes on the filter plate on the side of the liquid inlet. Once these leaks are filled with solid objects, paint may splash when flowing through, which not only significantly reduces the filtration efficiency and quality of the paint, but also may cause unclean working environment. More seriously, in the long-term use process, the paint directly impacts the area on the filter plate that is closely connected to the liquid inlet, so this part is under high wear pressure, which accelerates the damage process of the filter. Frequent replacement of the filter not only increases maintenance costs, but also affects the continuity and efficiency of the production line.

[0021] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figures 1 to 6 As shown, a paint filtering device in paint production and processing comprises a filter box 1, three filter plates 12 are arranged inside the filter box 1, the filter plates 12 are woven from metal materials, the three filter plates 12 are all arranged obliquely, and the inclination direction of the middle filter plate 12 is opposite to the direction of the upper and lower filter plates 12, both ends of the three filter plates 12 are fixedly connected with fixed plates 16, and one end of the fixed plates 16 on both sides is fixedly connected with a slider 17, a shaking component is arranged on one side of the filter box 1, and the shaking component is used to drive the three filter plates 12 to shake up and down synchronously inside the filter box 1, a rectangular groove 2 is opened on one side of the upper end of the filter box 1, and a telescopic sleeve 5 is arranged inside the rectangular groove 2, and a reciprocating moving component is arranged on the upper end of the filter box 1, and the reciprocating moving component is used to drive the lower end of the telescopic sleeve 5 to move back and forth in the rectangular groove 2; The reciprocating motion component is used to realize the back and forth movement of the lower end of the telescopic sleeve 5 in the rectangular groove 2. The reciprocating motion can change the path and angle of the paint entering the filter box 1, so that the solid impurities in the paint are more evenly distributed on the filter plate 12, avoiding the problem of local excessive wear and blockage, and reducing the replacement frequency of the filter plate 12. Secondly, by changing the position of the liquid inlet, the filtering area of ​​the filter plate 12 can be more effectively utilized, thereby improving the filtering efficiency; the shaking component is used to realize the synchronous up and down shaking of the three filter plates 12 inside the filter box 1. The shaking action can effectively prevent the solid impurities in the paint from staying in the leakage holes of the filter plates 12 for a long time, avoiding the blockage of the leakage holes, thereby ensuring the smooth flow and filtering efficiency of the paint. Secondly, the shaking also helps to loosen and remove impurities that have been attached to the filter plate 12, reducing the burden on the filter plate 12 and extending the service life of the filter plate 12. In addition, through shaking, the paint on the filter plate 12 can be more evenly distributed, further improving the filtering quality and purity of the paint.

[0024] Further, such as Figures 1 to 3As shown, the shaking assembly includes a first mounting frame 9 fixedly connected to the lower end of the end surface of one side of the filter box 1, a first servo motor 10 is arranged on one side of the inner wall of the first mounting frame 9, a rotating wheel 19 is fixedly connected to the output end of the first servo motor 10, a connecting rod 8 is rotatably connected to the upper end of the rotating wheel 19, and the upper end of the connecting rod 8 is rotatably connected to the upper end of a slider 17 on one side, and slide grooves are provided on both sides of the middle part of the filter box 1, and the slider 17 is slidably connected in the slide grooves; In the paint filtering device, the shaking assembly is composed of a first mounting frame 9, a first servo motor 10, a rotating wheel 19 and a connecting rod 8. The first mounting frame 9 is firmly connected to the lower end of one side end surface of the filter box 1, providing a solid support for it. When the first servo motor 10 receives a start signal, its output end starts to rotate at a high speed, driving the rotating wheel 19 fixedly connected thereto to rotate accordingly. The rotating wheel 19 is rotationally connected to the connecting rod 8 and the rotating connection is not in the middle of the rotating wheel 19. Therefore, when the rotating wheel 19 rotates, the connecting rod 8 will also swing accordingly, and the upper end of the connecting rod 8 is rotationally connected to the upper end of the slider 17 on one side. Then, the slider 17 is slidably connected to the slide grooves opened on both sides of the middle part of the filter box 1. This design ensures that when the connecting rod 8 swings, it can push the slider 17 to do up and down reciprocating motion in the slide groove. Since the slider 17 is fixedly connected to the two ends of the filter plate 12, when the slider 17 moves up and down, it will drive the entire filter plate 12 to shake up and down synchronously inside the filter box 1. This shaking action can not only effectively prevent solid impurities in the paint from clogging the leakage holes of the filter plate 12, but also loosen and remove impurities attached to the filter plate 12, thereby improving the filtration efficiency and extending the service life of the filter plate 12.

[0025] Further, such as Figure 2 , Figure 5 , Figure 6 As shown, the reciprocating moving assembly includes a fixed block 14 fixedly connected to the upper end of the inner wall of the filter box 1, and a reciprocating screw rod 13 is rotatably connected to the fixed block 14. The outer wall of the reciprocating screw rod 13 is transmission-connected with a transmission block 18, one end of the transmission block 18 is fixedly connected to the lower end of the telescopic sleeve 5, and the lower end of the telescopic sleeve 5 passes through the transmission block 18. The end of the transmission block 18 away from the telescopic sleeve 5 is slidably connected to the filter box 1 and the sliding direction is parallel to the reciprocating screw rod 13. Both sides of the middle of the outer wall of the reciprocating screw rod 13 are fixedly connected. The reciprocating moving assembly also includes a fixed block 21 connected to the filter box 1. A fixed rod 3 is provided in the middle of one side of the end, one end of the fixed rod 3 is fixedly connected to the upper end of the outer wall of the telescopic sleeve 5, the upper end of the telescopic sleeve 5 is fixedly connected to a flange 4, a second mounting bracket 28 is fixedly connected to one side of the middle part of the rear end surface of the filter box 1, and a second servo motor 29 is arranged on the end surface of the second mounting bracket 28 close to the filter box 1, and a driving pulley 27 is fixedly connected to the output end of the second servo motor 29, and a toothed belt 25 is connected to the external transmission of the driving pulley 27, and both sides of the toothed belt 25 are connected to the driven pulley 20, and one side of the driven pulley 20 is fixedly connected to the reciprocating screw rod 13.

[0026] In the paint filtering device, the reciprocating moving component realizes the back and forth movement of the lower end of the telescopic sleeve 5 in the rectangular groove 2. When the liquid is injected, the output end of the second servo motor 29 starts to rotate, driving the active pulley 27 fixedly connected thereto to rotate accordingly. The active pulley 27 is connected to the driven pulleys 20 on both sides through the toothed belt 25. Therefore, when the active pulley 27 rotates, the toothed belt 25 and the driven pulley 20 are driven to rotate together. Among them, the driven pulley 20 on one side is fixedly connected to the reciprocating screw 13. Therefore, when the driven pulley 20 rotates, the reciprocating screw 13 is driven to rotate synchronously. The outer wall of the reciprocating screw 13 is connected to the transmission block 18. One end of the transmission block 18 is fixedly connected to the lower end of the telescopic sleeve 5. When the reciprocating screw 13 rotates, the transmission block 18 is connected to the lower end of the telescopic sleeve 5. Due to the presence of the stopper 21, the transmission block 18 will reciprocate along the axial direction of the reciprocating screw 13. This movement is achieved through the threaded cooperation between the screw and the transmission block 18, which ensures the accuracy and stability of the movement. At the same time, the end of the transmission block 18 away from the telescopic sleeve 5 is slidably connected to the filter box 1, and the sliding direction is parallel to the reciprocating screw 13. This design ensures that the transmission block 18 can drive the lower end of the telescopic sleeve 5 to move back and forth in the rectangular groove 2 when moving, thereby changing the path of the paint entering the filter box 1. In addition, one end of the fixed rod 3 is fixedly connected to the upper end of the outer wall of the telescopic sleeve 5, providing additional support and stability for the telescopic sleeve 5. The upper end of the telescopic sleeve 5 is also fixedly connected to a flange 4, which is convenient for connecting with the paint delivery pipeline. Further, as Figures 2 to 5 As shown, a driving gear shaft 6 is fixedly connected to the middle part of the driven pulley 20 on the other side, and one end of the driving gear shaft 6 is meshedly connected to a bevel gear shaft 7, and the lower end of the bevel gear shaft 7 extends into the lower end of the inner part of the filter box 1 and passes through three filter plates 12, and the outer wall of the bevel gear shaft 7 is located at the upper end of the three filter plates 12, and a spoiler extrusion assembly is provided, and the spoiler extrusion assembly includes a connecting plate 22 fixedly connected to the outer wall of the bevel gear shaft 7, and both sides of the lower end of the connecting plate 22 are fixedly connected to telescopic springs 23, and the lower ends of the two telescopic springs 23 are fixedly connected to a buffer plate 24, and the lower end of the buffer plate 24 is fixedly connected to a spoiler block 15, and the cross-section of the spoiler block 15 is spiral, and the lower end of the spoiler block 15 is evenly spaced and rotatably connected to a plurality of balls 26, and the outer wall of the balls 26 is in contact with the upper end surface of the filter plate 12, and one side of the lower end surface of the filter box 1 is fixedly connected to a drain pipe 11 for draining liquid; In the paint filtering device, the drive of the second servo motor 29 not only realizes the reciprocating movement of the lower end of the telescopic sleeve 5 in the rectangular groove 2, but also drives the rotation of the driving gear shaft 6. The driving gear shaft 6 is connected with the bevel gear shaft 7 through meshing, and the rotational power is transmitted to the bevel gear shaft 7, so that it rotates synchronously. The lower end of the bevel gear shaft 7 extends into the interior of the filter box 1 and passes through the three filter plates 12. The outer wall of the part located at the upper end of the filter plate 12 is installed with a spoiler extrusion assembly, which is composed of a connecting plate 22, a telescopic spring 23, a buffer plate 24 and a spoiler block 15. When the bevel gear shaft 7 rotates, it will drive the connecting plate 22 and the spoiler block 15 below it to rotate together. The cross section of the spoiler block 15 is a spiral line shape. This design enables it to effectively disturb the flow of paint during rotation, so that the solid impurities in the paint are more evenly distributed on the filter plate 12, avoiding local blockage and making the paint flow more evenly on the surface of the filter plate 12. At the same time, the ball 26 at the lower end of the spoiler block 15 is in close contact with the upper end surface of the filter plate 12, which not only reduces the friction resistance, but also enables the spoiler block 15 to Solid materials are squeezed and crushed to prevent particles from adhering to the surface of the filter plate 12, further improving the filtering efficiency of the paint. In addition, the existence of the telescopic spring 23 and the buffer plate 24 provides a certain elastic support, i.e., buffering, for the spoiler block 15, so that when the shaking component drives the filter plate 12 to shake up and down, the spoiler block 15 and the ball 26 will not interfere with the up and down shaking of the filter plate 12. As the paint flows and filters, the pure paint will eventually pass through the three layers of filter plates 12 with different mesh sizes and will converge to the bottom of the filter box 1 and be discharged through the drain pipe 11.
