Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and in particular to a window-type semi-transparent ink printing device. Background Technology

[0002] In the process of printing semi-transparent ink for windows, screen printing equipment is usually used. The basic working principle is: ink is applied to the screen, and a squeegee is used to scrape the surface of the screen, allowing the ink to pass through the opening area of ​​the screen and be printed onto the surface of the substrate (such as glass, plastic, and other window materials). However, in the actual printing process, especially when printing small areas (such as the button area of ​​a smartwatch, the decorative ring of a camera, etc.), due to the small printing area, the ink is easy to accumulate on both sides of the squeegee during the ink scraping process, forming two residual ink marks. On the one hand, if the residual ink is not cleaned in time, it may drip onto the printing area, causing printing pollution or uneven light transmission. On the other hand, it also leads to ink waste.

[0003] Therefore, a semi-transparent ink printing device with a viewing window was designed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a semi-transparent ink printing device with a window. It solves the problem that in screen printing of semi-transparent ink with a window, ink tends to accumulate on both sides of the squeegee during small-area printing, forming residual ink marks. This can contaminate the printing area, affecting the uniformity of light transmission, and also waste ink, requiring frequent cleaning and affecting production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A semi-transparent ink printing device with a screen printing machine includes a screen printing machine body, a connecting plate located at the bottom of the screen printing machine body, and a scraper located at the bottom of the connecting plate. Limiting plates are fixedly provided on both sides of the scraper to form an inwardly constricted shape with the scraper, so as to prevent ink overflow during printing.

[0006] Preferably, two mounting bases are fixedly installed on the main body of the screen printing equipment, and the bottoms of the two mounting bases are fixedly connected to the connecting plate. Preferably, the limiting plates are symmetrically distributed to guide and collect the ink overflowing from both sides of the scraper to the inner side of the limiting plates.

[0007] Preferably, the scraper and the limiting plate are made by an integral molding process, and the material is a hard aluminum alloy substrate. The scraper blade is plated with a hard chrome layer to improve wear resistance.

[0008] Preferably, a rubber strip is fixedly provided at the bottom of both the scraper and the limiting plate. The rubber strip is a soft silicone scraper with a Shore A50 hardness, which makes light contact with the wire mesh surface.

[0009] Preferably, a mounting block is fixedly provided on the top of the scraper. The mounting block is T-shaped, and the horizontal portion of the T-shaped mounting block is parallel to the connecting plate.

[0010] Preferably, the top of the connecting plate is fixedly connected to the mounting base, and the connecting plate has a mounting groove on the side near the scraper.

[0011] Preferably, the mounting groove matches the mounting block, and the mounting block can be slidably inserted along the mounting groove.

[0012] Preferably, multiple locking blocks are fixedly provided on both sides of the mounting block, and the multiple locking blocks are hemispherical and made of rubber.

[0013] Preferably, multiple slots matching the card block are provided on both symmetrical sides of the inner wall of the mounting groove, and the card block is engaged and fixed with the slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves both high-efficiency printing and ink recovery through an innovative squeegee design. The inwardly tapering limiting plate and squeegee complete the pattern transfer during the printing stroke. On the return stroke, the inward tapering effectively collects excess ink from both sides, significantly improving ink recovery rate, reducing waste, and facilitating the reuse of recovered ink. It also ensures a cleaner screen surface during secondary printing. The silicone strip at the bottom provides flexible protection for the screen surface while maintaining effective ink scraping, extending its service life. Furthermore, the mounting block and mounting groove allow for quick disassembly and replacement of the squeegee. This solves the problem in semi-transparent screen printing where ink easily accumulates on both sides of the squeegee during small-area printing, forming residual ink marks that can contaminate the printing area, affecting light transmission uniformity, and causing ink waste.

[0022] Please see Figures 1-4 A semi-transparent ink printing device with a window includes a screen printing device body 1, a connecting plate 2 located at the bottom of the screen printing device body 1, and a scraper 3 located at the bottom of the connecting plate 2. Limiting plates 31 are fixedly provided on both sides of the scraper 3 to form an inwardly constricted shape with the scraper 3, so as to prevent ink overflow during printing. Two mounting seats 11 are fixedly installed on the screen printing device body 1, and the bottom of the two mounting seats 11 is fixedly connected to the connecting plate 2. The limiting plates 31 are symmetrically distributed and are used to guide and collect the ink overflowing from both sides of the scraper 3 to the inner side of the limiting plates 31. The scraper 3 and the limiting plates 31 are made by an integral molding process and are made of hard aluminum alloy substrate. The scraper blade is plated with hard chrome to improve wear resistance. Rubber strips 32 are fixedly installed at the bottom of both the scraper 3 and the limiting plates 31. The rubber strips 32 are soft silicone scraper strips with Shore A50 hardness and lightly contact the screen surface. The top of the scraper 3 is fixedly installed with a mounting block 33. The mounting block 33 is T-shaped and the horizontal part of the T-shaped mounting block 33 is parallel to the connecting plate 2. When using this device, the window body to be printed is placed at the bottom of the screen. After placement, the entire screen printing equipment body 1 is driven to move the connecting plate 2 and squeegee 3 installed at the bottom of the mounting base 11 down to the screen. At the same time, the two squeegees 3 are driven to move along the screen to achieve printing. Before printing, ink is dripped onto the screen surface. The two squeegees 3 move back and forth along the screen. When they move back, they are limited by the limiting plates 31 on both sides of the squeegee 3. The overflow ink on both sides is recovered by the U-shaped limiting plate, which is convenient for subsequent reuse. The design of the squeegee 3 and the limiting plate 31 is adopted to complete the pattern transfer during the printing stroke. During the return stroke, the inward-curving limiting plate 31 guides and collects the overflow ink on both sides. The bottom silicone strip 32 gently contacts the screen, and the chrome-plated blade provides wear resistance. The overflow ink recovery rate is greatly improved, and ink waste is reduced.

[0023] The top of the connecting plate 2 is fixedly connected to the mounting base 11. The connecting plate 2 has a mounting groove 21 on the side near the scraper 3. The mounting groove 21 matches the mounting block 33, and the mounting block 33 can slide and insert along the mounting groove 21. Multiple locking blocks 34 are fixedly provided on both sides of the mounting block 33. The multiple locking blocks 34 are hemispherical and made of rubber. Multiple locking slots 22 that match the locking blocks 34 are provided on both symmetrical sides of the inner wall of the mounting groove 21. The locking blocks 34 and the locking slots 22 are locked and fixed. By using the mounting block 33 and the mounting groove 21 together, the scraper 3 can be quickly disassembled and assembled. In order to avoid the scraper 3 from being difficult to clean the surface ink after long-term use, the entire mounting block 33 can be manually pulled out along the mounting groove 21 for replacement. After replacement, the new scraper 3 is inserted into the mounting groove 21 along the mounting block 33. During the insertion process, the locking block 34 deforms and can be locked into multiple locking grooves 22 in sequence to achieve reset and fixation. This completes the disassembly and assembly, which is convenient for cleaning. The mounting groove 21 and the T-shaped mounting block 33 are fitted with a clearance (fitting tolerance H8 / f7) to ensure smooth sliding while avoiding shaking. The hemispherical rubber block 34 (Shore A60 hardness) and the trapezoidal groove 22 are designed to achieve buffering through elastic deformation when inserted, and the final locking force is controlled within the range of 8-12N, which ensures that it can be operated with one hand and can remain locked under printing vibration conditions.

[0024] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
