[0002] Screen printing is extremely widely used and is closely related to our lives. Screen printing refers to using a silk screen as a base and using a photosensitive platemaking method to make a screen printing plate with images. Printing is carried out based on the basic principle that the mesh holes of the image and text part of the screen printing plate can pass ink, while the mesh holes of the non-image and text part cannot pass ink. Then, in order to use it normally next time, the screen printing plate needs to be cleaned before that.
[0003] After printing, the screen printing machine in the prior art will have a lot of ink adhered to the screen printing plate. If it is not cleaned in time, the ink adhered to the screen printing plate will become more stubborn and difficult to clean. It is time-consuming and laborious to clean it by general cleaning methods. At the same time, in order to clean the stubborn ink, a cleaning brush is often used to rub it repeatedly. In this way, the screen is easily seriously damaged during the repeated rubbing of the cleaning brush, resulting in damage. Utility Model Content

DETAILED DESCRIPTION
[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0021] Example 1
[0022] A cleaning device for screen printing, such as Figure 1-Figure 5 As shown, it includes a base frame 1, a mobile unit and an electric telescopic bracket 4; the base frame 1 is equipped with two symmetrically distributed mobile units; all mobile units are equipped with a total of four symmetrically distributed electric telescopic brackets 4;
[0023] It also includes a V-shaped accumulation plate 5, a spray plate 6, a limit plate 7, a drain pipe 501 and a water inlet pipe 502; the telescopic parts of all the electric telescopic brackets 4 are fixedly connected with a V-shaped accumulation plate 5, and a water outlet trough 5b is provided at the bottom of the V-shaped accumulation plate 5, the diameter of the water outlet trough 5b is consistent with the size of the screen printing plate to be cleaned, and an inclined groove 5a is provided on the V-shaped accumulation plate 5; the V-shaped accumulation plate 5 is installed with a spray plate 6; the base frame 1 is installed with two limit plates 7 which are symmetrically distributed on the left and right; the V-shaped accumulation plate 5 is installed with two symmetrically distributed drain pipes 501; the spray plate 6 is connected with the water inlet pipe 502.
[0024] The mobile unit includes an electric slide rail 2 and an electric slider 3; the base frame 1 is equipped with two electric slide rails 2 which are symmetrically distributed on the left and right; each electric slide rail 2 is equipped with an electric slider 3, and the electric slider 3 is fixedly connected to the electric telescopic bracket 4 on the corresponding side.
[0025] The utility model works specifically as follows:
[0026] First, the drain pipe 501 is connected to the external wastewater collection equipment, the water inlet pipe 502 is connected to the water pump, and the electric slide rail 2, the electric slider 3 and the electric telescopic bracket 4 are connected to the external power supply; initially, the screen printing plate to be cleaned is placed manually between the two limit plates 7, supported by the two limit plates 7, and then the water pump is turned on to input the cleaning liquid into the water inlet pipe 502 and flow out from the spray plate 6, and then the cleaning liquid passes through the water outlet trough 5b to flow to the surface of the screen printing plate, and at the same time, the electric telescopic bracket 4 is controlled to drive the V-shaped accumulation plate 5 and the spray plate 6 to move downward until the water outlet trough 5b contacts the surface of the screen printing plate. It should be noted that at this time, the flow rate input to the water inlet pipe 502 is much greater than the flow rate flowing out of the water outlet trough 5b, and the flow rate flowing out of the water outlet trough 5b is much greater than the amount of cleaning liquid passing through the screen. In this way, due to the provision of the V-shaped accumulation plate 5, excess cleaning liquid will accumulate inside it, and when the accumulated amount exceeds the drain When the water pipe 501 is passed through, the water is discharged from the drain pipe 501. Since the water outlet groove 5b is in contact with the surface of the screen printing plate, a large amount of cleaning liquid can be reduced from penetrating other surfaces of the screen printing plate that are not in contact with the water outlet groove 5b, thereby achieving the effect of the cleaning liquid accumulated in the V-shaped accumulation plate 5 to immerse the surface of the screen printing plate within the size of the water outlet groove 5b. The immersion can effectively remove the stubborn ink in the cleaning area, avoiding the problem that the stubborn ink on the existing screen printing plate is difficult to clean. At the same time, different from the existing immersion technology, the immersion is gradually carried out in a small range in the cleaning area, solving the problem that the immersion cleaning efficiency of a large range of stubborn ink is low and the stubborn ink cannot be removed well. In addition, different from the existing flushing technology, the problem that the cleaning liquid flushes the screen surface with a large impact force to remove the stubborn ink and causes damage is avoided, and the problem that the screen is seriously damaged during the repeated friction of the screen using a cleaning brush in the existing technology is avoided.
[0027] It should be noted that the V-shaped flow accumulation plate 5 is provided with an inclined groove 5a, thereby increasing the amount of cleaning liquid accumulated on the V-shaped flow accumulation plate 5, avoiding the problem that the cleaning liquid is discharged before the stubborn ink is melted due to insufficient accumulated cleaning liquid, resulting in poor immersion effect;
[0028] Subsequently, the electric slide 3 is controlled by the electric slide rail 2 to move back and forth repeatedly, and the electric telescopic bracket 4, the V-shaped flow accumulation plate 5 and the spray plate 6 are driven to move, so that the cleaning liquid can repeatedly soak different areas, thereby realizing the soaking of one side of the screen printing plate surface, and then, the water pump and the external power supply are turned off, the screen printing plate is manually removed from the limit plate 7, and it is turned over and placed again between the two limit plates 7, and at the same time, the water pump and the external power supply are turned on, and the above steps are repeated to complete the soaking of the other side of the screen printing plate surface.
[0029] Example 2
[0030] On the basis of Example 1, Figure 2-Figure 3 As shown, it also includes an electric push rod 601, a corrugated telescopic plate 602 and an electric sprayer 603; four symmetrically distributed electric push rods 601 are installed at the bottom of the spray plate 6; the telescopic parts of all electric push rods 601 are commonly fixed to the corrugated telescopic plate 602; the corrugated telescopic plate 602 is provided with a plurality of electric sprayers 603.
[0031] The utility model works specifically as follows:
[0032] Initially, the electric push rod 601 and the electric sprayer 603 are connected to the external power supply. When the cleaning liquid enters from the water inlet pipe 502 and flows through the spray plate 6 and the water outlet tank 5b to the surface of the screen printing plate, the external power supply is controlled to open the electric sprayer 603, so that the cleaning liquid is sprayed from the electric sprayer 603 to the water outlet tank 5b. At the same time, the electric sprayer 603 can control the flow rate of the cleaning liquid spray, thereby realizing the control of the flow rate of the cleaning liquid under different cleaning requirements, reducing the waste of the cleaning liquid, and avoiding the mismatch between the flow rate and the cleaning requirements, which causes excessive flow and damage to the screen surface. The problem of excessive impact force can be solved. At the same time, the telescopic part of the electric push rod 601 can be controlled to move downward by turning on the external power supply, so that the corrugated telescopic plate 602 can be telescoped downward, and the electric sprayer 603 can be driven to move, so that the electric sprayer 603 is closer to the water outlet trough 5b, thereby achieving a more precise injection of the cleaning liquid, and when the cleaning liquid accumulates in the V-shaped accumulation plate 5, the electric sprayer 603 can be inserted into it. In this way, the ejected cleaning liquid disturbs the accumulated cleaning liquid, so that the cleaning liquid and stubborn ink can be better integrated, thereby improving the immersion efficiency.
[0033] Example 3
[0034] On the basis of Example 2, Figure 4-Figure 5As shown, it also includes a wave cleaning plate 701, a water supply tank 702 and an electric nozzle 703; all the limiting plates 7 are equipped with a wave cleaning plate 701, and the wave cleaning plate 701 is divided into several sections along the direction of the limiting plate 7, each section of the wave cleaning plate 701 is arranged in a U shape, and the curved part of the wave cleaning plate 701 is arranged on the opposite sides of the two wave cleaning plates 701; the limiting plate 7 is equipped with a water supply tank 702, and the water supply tank 702 is provided with a water inlet; the wave cleaning plate 701 is provided with several electric nozzles 703, and the several electric nozzles 703 are distributed between two adjacent sections of the wave cleaning plate 701, and the limiting plate 7 is provided with several drainage grooves 7a.
[0035] The surface of the wave cleaning plate 701 is made of sponge material; the wave cleaning plate 701 has an increased cleaning ability for the screen printing plate frame, thereby avoiding the problem of neglecting the cleaning of the printing plate frame when cleaning the screen, resulting in a large amount of ink remaining on the printing plate frame and a low cleaning effect.
[0036] It also includes springs 704 and arc-shaped support plates 705; the limiting plate 7 is fixedly connected to a plurality of springs 704, and each spring 704 is located on opposite sides of the two wave cleaning plates 701, and each spring 704 corresponds to the position of each section of the wave cleaning plate 701; each spring 704 is fixedly connected to an arc-shaped support plate 705, and the arc-shaped support plate 705 is in contact with the opposite sides of the two wave cleaning plates 701.
[0037] Each arc-shaped support plate 705 is consistent in size with each section of the wave cleaning plate 701 ; the arc-shaped support plate 705 increases the supporting effect of the wave cleaning plate 701 , thereby preventing the wave cleaning plate 701 from excessive deformation due to long-term use.
[0038] The utility model works specifically as follows:
[0039] First, the water inlet provided on the water supply tank 702 is connected to the water pump, the electric nozzle 703 is connected to the external power supply, and the drainage groove 7a is connected to the external wastewater collection device. When the screen printing plate is immersed, part of the cleaning liquid mixed with the stubborn ink will splash onto the screen printing plate frame. In this way, the electric nozzle 703 can be turned on by controlling the external power supply, and part of the cleaning liquid is input from the water inlet provided on the water supply tank 702 and sprayed out by the electric nozzle 703, so that the cleaning liquid can rinse the screen printing plate frame, thereby avoiding the problem of a large amount of ink remaining on the screen printing plate frame and low cleaning effect. At the same time, the surface of the wave cleaning plate 701 is made of sponge material, which increases the cleaning ability of the plate to the screen printing plate frame while limiting the screen printing plate, and the electric nozzles 703 are evenly distributed between two adjacent sections of the wave cleaning plates 701, so that the cleaning liquid sprayed by the electric nozzle 703 has enough space to clean the printing plate frame, and the cleaning liquid after rinsing will be discharged through the drainage groove 7a;
[0040] At the same time, the spring 704 and the arc-shaped support plate 705 can support the wave cleaning plate 701, and when the screen printing plate generates pressure on the wave cleaning plate 701, the spring 704 will be compressed, and the compressed spring 704 will generate a rebound force in the direction of the screen printing plate, so that the wave cleaning plate 701 made of sponge material is squeezed, thereby squeezing out the sewage mixed with the cleaning liquid and stubborn ink in the wave cleaning plate 701 to avoid residue and increase the service life of the wave cleaning plate 701;
[0041] It should be noted that each arc support plate 705 is consistent in size with each section of the wave cleaning plate 701, thereby increasing the supporting effect of the arc support plate 705 on the wave cleaning plate 701 and avoiding the problem of excessive deformation of the wave cleaning plate 701 due to long-term use.
[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
