Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a water circulation mechanism for cleaning a printing screen. Background Art

[0002] Screen printing refers to the use of silk screen as a base and the use of photosensitive platemaking methods to make a screen with images. Screen printing consists of five major elements: screen, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the image part of the screen can pass through the ink, while the mesh holes of the non-image part cannot pass through the ink. When printing, ink is poured into one end of the screen printing plate, and a certain amount of pressure is applied to the ink part of the screen with a scraper. At the same time, it moves at a constant speed toward the other end of the screen. During the movement, the ink is squeezed from the mesh holes of the image part by the scraper onto the substrate.

[0003] A Chinese patent application numbered CN202320388715.3 discloses a screen printing mold cleaning device, the technology of which is as follows: including a water tank, a frame, a fixing structure, and a flushing structure, characterized in that: the frame includes a base, support walls are fixed on the upper side of the base near both sides, a top wall is fixed on the top of the two support walls, baffles are fixed between the two support walls near both sides, a fixing structure is provided between the two baffles, the fixing structure includes two fixing frames, two openings are provided on the side of the fixing frame, and slots are provided on the sides of the two openings, a flushing structure is fixed under the top wall, and the flushing structure includes several telescopic rods, and a flat-head nozzle is fixed at the bottom of each telescopic rod.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figure 2 、 5 As shown, a water circulation mechanism for cleaning a printing screen includes a supporting cabinet 1, an LED lighting device 2 is fixedly connected to the interior of the supporting cabinet 1, a fixing structure 3 is fixedly connected to the supporting cabinet 1, the fixing structure 3 is located in front of the LED lighting device 2, and the fixing structure 3 is used to provide a supporting force and a clamping force for the screen, a water receiving container 4 is also fixedly connected to the supporting cabinet 1, the water receiving container 4 is located below the fixing structure 3, a drain port 13 is provided on one side of the water receiving container 4, a water storage tank 14 is fixedly connected to the bottom of the water receiving container 4, the drain port 13 drains water to the opening of the water storage tank 14, a water pipe 15 is provided in the water storage tank 14, and the water pipe 15 is used to connect a water suction pump to absorb water from the water storage tank 14 to clean the screen.

[0024] like Figure 1 、 3As shown in Figures 4 and 5, the top surface of the water receiving container 4 is in the shape of an inverted quadrangular pyramid, with a filter port 5 in the middle of the water receiving container 4. The edge of the filter port 5 is recessed downward to form a card interface 6. A card connection portion 8 is provided on the top outer peripheral wall of the filter 7. The filter 7 is abutted against the card interface 6 through the card connection portion 8, thereby realizing the detachability of the filter 7. A number of filter holes 9 are provided on the filter 7 for filtering solid glue in the water. A handle 10 is rotatably connected to the inner peripheral wall of the top of the filter 7. A guide groove 11 is provided in the middle section of the bottom surface of the inner cavity of the water receiving container 4. The lowest point of the guide groove 11 is connected to the drain outlet 13. Drainage portions 12 that converge thereto are provided on both sides of the guide groove 11, so that water can flow accurately and quickly into the water storage tank 14.

[0025] like Figure 1 As shown, the fixing structure 3 includes a first clamping strip 31 and a second clamping strip 32, and a cavity for clamping the screen is left between the first clamping strip 31 and the second clamping strip 32. The distances from the top and bottom surfaces of the cavity to the LED lighting device 2 increase successively. The length of the fixing structure 3 is less than two-thirds of the length of the supporting cabinet 1 and the water receiving container 4. Silicone pads 33 are provided on the two surfaces facing each other in the cavity. The silicone pads 33 are used to increase the friction between the clamping and the screen, thereby making the screen clamping more stable. In addition, the silicone pads 33 are elastic and can better protect the frame on the screen.

[0026] Working principle:

[0027] When there is water in the water tank 14, use a water suction pump to connect the water pipe 15 on the water tank 14, and then use a water gun to connect the water suction pump, and then clamp the screen to be cleaned from the left side of the fixed structure 3 into the cavity between the first clamping strip 31 and the second clamping strip 32. At this time, the upper end of the screen leans on the LED lighting device 2, and then turn on the switch of the water gun to start cleaning the screen. When cleaning the screen, the water flow and the washed solid glue flow along the surface of the screen into the cavity of the fixed structure 3 or directly into the water receiving container 4. When a screen is cleaned, if there is solid glue left in the cavity of the fixed structure 3, the cavity can be flushed with a water gun, so that the solid glue flows from the left end of the fixed structure 3 into the water receiving container 4. Because the top surface of the water receiving container 4 is an inverted quadrangular pyramid, the water flow will flow along the cone surface toward the filter port 5, and then flow into the filter 7. The cleaned water passes through the filter After filtering by 7, the solid glue remains in the filter 7, and the water will pass through the filter holes 9 on the filter 7 and flow into the inner cavity of the water receiving container 4. Since the guide groove 11 on the inner cavity is inclined, the water will flow quickly into the water storage tank 14 along the inclined surface. If the water volume is large, two drainage parts 12 that flow into the guide groove 11 are provided on both sides of the guide groove 11, so that all the filtered water can accurately flow into the water storage tank 14. The water in the water storage tank 14 is sucked out through the water pipe 15 by the water suction pump, and finally sprayed out by the water gun to clean the screen again, so as to achieve the effect of water circulation and reduce the waste of water resources. When there is too much solid glue, you can turn the handle 10 on the filter 7 to take out the filter 7, and then pour all the cleaned solid glue into the trash can, and then you can install the filter 7 back on the card interface 6 in the filter port 5 and use it again.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
