Description

Technical Field

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

[0002] Screen printing refers to using a silk screen as a base and making a screen printing plate with images through a photosensitive plate-making method. Screen printing consists of five major elements: screen printing plate, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the screen printing plate with images can pass through the ink, while the mesh holes of the non-image parts cannot pass through the ink.

[0003] During the screen printing process, a large amount of ink will adhere to the bottom of the screen printing scraper due to the reciprocating operation. The ink adhered to the bottom of the screen printing scraper needs to be cleaned in time, otherwise it will affect the printing quality of the screen printed product.

[0004] However, screen printing scrapers have various shapes, and the cleaning device has to match the shapes of different screen printing scrapers during cleaning, resulting in low cleaning efficiency; therefore, it does not meet the existing needs. In this regard, we propose a cleaning device for screen printing scrapers. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figure 1 and Figure 2 As shown, a cleaning device for a screen printing scraper comprises a fixed seat 1, and two fixed plates 5 are fixed on the upper surface of the fixed seat 1, and the upper ends of the two fixed plates 5 are slidably plugged with reinforcement connecting plates 6, and the tops of the two reinforcement connecting plates 6 are fixed with tension adjustment plates 7, and the four end corners of the fixed seat 1 are fixed with support frames 2. A cleaning cloth strip 3 is installed between the four support frames 2, and a support rod 4 is installed on the inner side of the cleaning cloth strip 3. The end of the support rod 4 is rotatably connected to the support frame 2, and the cleaning cloth strip 3 passes under the tension adjustment plate 7, and the screen printing scraper is placed above the cleaning cloth strip 3, and the cleaning cloth strip 3 is pulled downward by using the tension adjustment plate 7 to make the cleaning cloth strip 3 fit the outer surface of the screen printing scraper, and then the screen printing scraper is pulled to slide on the surface of the cleaning cloth strip 3, so that the screen printing scraper can be cleaned.

[0023] like Figures 2 to 4 As shown, a positioning groove 12 is provided at the top of the fixed plate 5, and the bottom end of the reinforcement connecting plate 6 is slidably inserted into the inner side of the positioning groove 12, and the bottom end of the reinforcement connecting plate 6 is fixedly inlaid with an adsorption magnet 10, and an electromagnet 11 is fixed inside the positioning groove 12, and return springs 13 are installed on both sides of the electromagnet 11, and the bottom end of the return spring 13 is fixed to the fixed plate 5, and the top end of the return spring 13 is inserted into the bottom end of the reinforcement connecting plate 6 and is detachably connected to the reinforcement connecting plate 6, and the adsorption magnet 10 and the electromagnet 11 are magnetically adsorbed and connected, and the magnetic adsorption force of the electromagnet 11 on the adsorption magnet 10 is greater than the sum of the elastic forces of the two return springs 13. After the electromagnet 11 is energized, it pulls the adsorption magnet 10 and the reinforcement connecting plate 6 downward, so that the reinforcement connecting plate 6 drives the tension adjustment plate 7 to move downward and pull the cleaning cloth strip 3, and adjusts the tension of the cleaning cloth strip 3 so that the top of the cleaning cloth strip 3 fits the bottom surface of the screen printing scraper.

[0024] like Figure 2 As shown, elastic bands 8 are fixed to the top ends of two support frames 2 on the same vertical plane, and a pressing block 9 is bonded to the middle of the bottom surface of the elastic bands 8. The pressing block 9 includes an outer shell and an inner core. The outer shell is made of rubber, and the inner core is made of logs. The elastic elastic bands 8 are used to pull the pressing block 9 downward, so that the pressing block 9 applies pressure from above the screen printing scraper, thereby increasing the contact friction between the screen printing scraper and the cleaning cloth strip 3.

[0025] Working principle: First, pull the two lower pressing blocks 9 upward, and then pass the screen printing scraper from under the two lower pressing blocks 9. At this time, the screen printing scraper is located between the cleaning cloth strip 3 and the lower pressing block 9. Then release the lower pressing block 9. At this time, the lower pressing block 9 of the elastic band 8 moves downward and applies a pressure to the screen printing scraper from above, pressing the screen printing scraper tightly against the top of the cleaning cloth strip 3. Then turn on the power of the device. After the power is turned on, the electromagnet 11 adds magnetic force and attracts the adsorption magnet 10 downward. At this time The adsorption magnet 10 drives the reinforcement connecting plate 6 and the tension adjustment plate 7 to move downward and causes the reinforcement connecting plate 6 to compress the positioning groove 12, and the tension adjustment plate 7 will pull the bottom of the cleaning cloth strip 3 downward when moving downward, so that the cleaning cloth strip 3 is tightly attached to the bottom surface of the screen printing scraper, and the friction between the screen printing scraper and the cleaning cloth strip 3 is increased, and finally the screen printing scraper is pulled to make the screen printing scraper slide between the lower pressing block 9 and the cleaning cloth strip 3, and the stains on the screen printing scraper will be cleaned by the cleaning cloth strip 3.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
