[0002] The paint filter is a device used to remove solid particles, impurities and gels from paint to ensure the purity and quality of the paint. It plays the following roles in the paint production process: Improve paint quality: remove insoluble matter and impurities to prevent paint surface defects. Protect production equipment: avoid wear and tear of spraying equipment caused by particles. Improve spraying effect: ensure uniform spraying and prevent nozzle clogging.

[0003] The existing paint filter generally pours the paint into the filter manually, and the solids in the paint are filtered by the filter, which is inconvenient and cumbersome. There are also existing methods of using pipes and faucets to fill the filter with the paint to be filtered. However, since the pore size of the filter used for paint filtration is small, the continuous input of paint can easily make the paint filtration speed lower than the paint input speed, resulting in paint overflow.

[0004] In order to solve the above problems, the present application provides a switch device and a fully automatic paint filter thereof, which can intermittently input paint and reduce the filtering pressure of the filter. Utility Model Content

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0029] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1As shown, a fully automatic paint filter includes a frame 1. A filter screen 2 is arranged in the middle of the frame 1. The aperture of the filter screen 2 can be adjusted according to actual needs. A housing 3 is arranged outside the filter screen 2. A discharge rack 4 is arranged at the bottom of the housing 3. The paint filtered by the filter screen 2 is collected by the discharge rack 4.

[0032] Embodiment 1: Switch device 5

[0033] like Figure 1-Figure 3 As shown, in order to achieve the purpose of intermittent feeding, the present application is also provided with a liquid storage tank 6 located in the middle of the frame 1 and above the filter screen 2. A liquid outlet 7 is provided at the bottom of the liquid storage tank 6. A switch device 4 is provided at the position of the liquid outlet 7. The switch device includes a plunger disk 8 made of rubber material. Drive rods 9 are respectively provided on both sides of the plunger disk 8.

[0034] Correspondingly, a slide rail 10 is fixedly provided at the position of the liquid storage tank 6 corresponding to the driving rod 9. The driving rod 9 is slidably arranged in the slide rail 10. A connecting rod 11 is hinged at the bottom of the driving rod 9. A rotating frame 12 is hinged at the end of the connecting rod 11. One end of the rotating frame 12 is hinged to the casing 3, and an output shaft 13 is hinged to the middle of the rotating frame 12. Among them, a cylinder 14 is connected to the bottom of the output shaft 13. When the cylinder 14 is working, it can drive the rotating frame 12 to swing clockwise, so that the connecting rod 11 moves, and then drives the driving rod 9 to be pushed and move upward along the slide rail 10, so that the plunger disk 8 abuts against the position of the liquid outlet 7, so as to close the liquid outlet 7 and prevent liquid from flowing out.

[0035] When the cylinder 14 works to drive the output shaft 13 downward, the rotating frame 12 rotates counterclockwise, thereby driving the connecting rod 11 to swing downward as a whole, and then driving the driving rod 9 to move downward, driving the plunger disk 8 away from the liquid outlet 7, so that the liquid outlet 7 discharges liquid.

[0036] Among them, a plurality of through holes 15 are arranged around the plunger disk 8 at the outer edge of the plunger disk 8. When the liquid in the liquid outlet 7 falls onto the plunger disk 8 through the liquid outlet 7, it flows out along the plurality of through holes 15 on the plunger disk 8 and enters the filter screen 2 in the housing 3 for filtration. The above arrangement can disperse the liquid discharge positions and reduce the filtration pressure of the filter screen 2 per unit area.

[0037] As described above, the cylinder 14 continuously reciprocates, so that the paint in the liquid outlet 7 intermittently flows into the filter screen 2 for filtration, thereby reducing the filtration pressure of the filter screen 2 per unit time, and also preventing the paint in the housing 3 from overflowing due to the filtration speed being lower than the liquid inlet speed.

[0038] Example 2: Feeding device 16

[0039] like Figure 3-Figure 5As shown, in order to achieve the purpose of multi-ratio feeding, the present application is provided with a feeding device 16 on one side of the frame 1. The feeding device 16 includes a batching box 17 arranged on one side of the frame 1. The corresponding additives can be loaded into the batching box 17. The batching box 17 is provided with a mounting hole 18 that passes through the batching box 17. A sliding rod 19 is slidably connected in the mounting hole 18. The diameter of the sliding rod 19 is smaller than the diameter of the mounting hole 18, and a plunger 20 is provided at the bottom of the sliding rod 19. When the plunger 20 abuts against the mounting hole 18, the mounting hole 18 cannot discharge liquid. When the plunger 20 is separated from the mounting hole 18, the additive flows out from the gap between the mounting hole 18 and the sliding rod 19.

[0040] Correspondingly, the top of the sliding rod 19 is fixedly connected with an inclined plate 21. The bottom of the inclined plate 21 is a plane, and a spring 22 is connected between the inclined plate 21 and the sliding rod 19.

[0041] The frame 1 may be provided with a filter screen 2 below the batching box 17, or may not be provided with the filter screen 2.

[0042] The frame 1 is provided with a feeding frame 23 communicated with the discharging frame 4 below the batching box 17 .

[0043] Optimally, when the output shaft 13 connected to one side of the rotating frame 12 drives the rotating frame 12 to rotate counterclockwise until the driving rod 9 moves downward, the rotating frame 12 swings to abut against the inclined plate 21, and the inclined plate 21 is squeezed to drive the sliding rod 19 to move downward. When the sliding rod 19 moves downward, the spring 22 is compressed and the plunger 20 at the bottom is opened, and the additive moves out of the batching box 17 and enters the feeding rack 23 and the discharging rack 4 to mix with the paint.

[0044] As described above, when it is necessary to add corresponding additives to the coating, the additives can be added during the process of filtering the coating, so that the additives and the coating are mixed in a certain ratio, and the ratio can be adjusted according to the aperture of the mounting hole 18 and the aperture of the liquid outlet 7. Through the above arrangement, the filtering process and the process of adding the additive are carried out simultaneously, thereby improving the production efficiency of the coating.

[0045] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
