Description

Technical Field

[0001] The invention belongs to the field of glass processing, and in particular relates to glass silk-screen printing equipment. Background Art

[0002] Nowadays, people often use the method of silk screen printing for printing on glass. Silk screen printing only requires that the ink on the silk screen plate be driven through the pattern on the surface of the silk screen plate, and the ink will directly pass through the holes on the surface of the silk screen plate to generate a pattern on the glass surface. However, in the process of driving the ink, the contact area between the ink and the air increases, which will cause the water inside the ink to evaporate quickly. After the water evaporates, the fluidity of the ink becomes worse, and it will become more viscous, and it is easy to block the holes on the silk screen plate. The present invention provides a glass silk screen printing device to solve the above problems. Summary of the invention

[0040] Furthermore, each stirring roller 19 is provided with a fifth slide groove 62, and a second slider 64 is provided inside each fifth slide groove 62 for sliding sealing. An arc-shaped elastic sheet 67 is fixedly provided on the side of each second slider 64 away from the fourth rotating shaft 54, and one end of each arc-shaped elastic sheet 67 extends out of the fifth slide groove 62, and a plurality of filtering holes 68 are provided on the end of each arc-shaped elastic sheet 67 extending out of the fifth slide groove 62.

[0041] Working principle: Initially, the printing plate is fixedly installed between the two support frames 33, and then a sufficient amount of ink is poured on the surface of the printing plate above the ink block 18, and then the glass to be screen-printed is installed between the clamping plates 13 below. A sufficient amount of water is filled into the water tank 50, and because of the obstruction of the slide plate 44, the water inside the water tank 50 will not fall directly through the water outlet 52.

[0042] When screen printing is required, the first drive motor 27 is first started, and the first drive motor 27 drives the first lead screw 28 to rotate, thereby driving the support plate 14 to move downward. When the bottom of the printing plate between the two support frames 33 contacts the glass surface below that needs screen printing, the first drive motor 27 stops driving. Then the second drive motor 31 is started, and the second drive motor 31 drives the second lead screw 30 to rotate. Driven by the second lead screw 30, the ink-driving device 16 starts to move in the direction where the ink is poured. When the ink-driving device 16 moves to the point where the ink is between the ink-driving block 18 and the scraper 17, the second drive motor 31 stops driving. Then start the second telescopic motor 21, and the second telescopic motor 21 drives the ink driving block 18 to gradually extend out of the fourth slide groove 71. During the descending process of the ink driving block 18, when the fourth rotating shaft 54 ​​inside the third slot 59 hits the convex head 61 on the surface of the push rod 58, the convex head 61 on the surface of the push rod 58 will push the fourth rotating shaft 54 ​​to overcome the elastic force of the second spring 60, and push the fourth rotating shaft 54 ​​into the third slot 59. When a convex head 61 passes through the fourth rotating shaft 54, the elastic force of the second spring 60 is restored to push the fourth rotating shaft 54 ​​back to its initial position.

[0043] When the ink-driving block 18 descends to a certain distance, the racks 23 on the circumferential surface of each stirring roller 19 connected to the fourth rotating shaft 54 ​​inside the third notch 59 will first contact the ink on the surface of the printing plate, and the stirring roller 19 will move forward and backward with the fourth rotating shaft 54 ​​under the action of the convex head 61. During the movement of the stirring roller 19, the racks 23 on the surface of the stirring roller 19 will stir the ink at the bottom. The fluidity of the ink will gradually deteriorate when it is exposed to the air for a long time, which can easily cause the holes on the printing plate to be blocked and affect the silk screen printing effect. Stirring the ink can effectively prevent the fluidity of the ink from deteriorating.

[0044] When the ink-driving head 24 below the ink-driving block 18 hits the surface of the printing plate, the second telescopic motor 21 is turned off, and the second drive motor 31 is started to reverse. Under the action of the first lead screw 28, the ink-driving device 16 will be driven to move to the other side. During the movement of the ink-driving device 16, the arc-shaped elastic sheet 67 extending from the inside of the stirring roller 19 will first scoop up the ink, and the ink scooped up by the arc-shaped elastic sheet 67 will flow to the ink-driving head 24 behind through the filter hole 68. The ink-driving head 24 at the bottom of the ink-driving device 16 will drive the ink forward together. During the forward movement, the ink-driving head 24 will drive the ink from the holes on the surface of the printing plate to the glass surface below to complete the silk screen printing on the glass. When there are some lumps or ink flakes that are not thoroughly ground in the ink, the arc-shaped elastic sheet 67 can shovel these lumps and ink flakes on the surface of the arc-shaped elastic sheet 67, which can effectively prevent the lumps of ink flakes from being driven by the ink-driving head 24 and blocking the holes on the surface of the printing plate.

[0045] When the ink-driving device 16 reaches the limit position, the second drive motor 31 stops driving, and then the first telescopic motor 35 is started. The output end of the first telescopic motor 35 extends, and at the same time drives the sliding shell 38 to slide out of the second slide groove 37. When the scraper 17 inside the sliding shell 38 contacts the printing plate below, the first telescopic motor 35 stops driving. Then the second telescopic motor 21 is started, and the output end of the second telescopic motor 21 retracts, while driving the ink driving block 18 back to the fourth slide groove 71. In the process of the ink driving block 18 returning to the fourth slide groove 71, when the fourth rotating shaft 54 ​​is pushed back to the third slot 59 by the convex head 61, the connecting rod 55 will synchronously retreat with the stirring roller 19. During the retreat process, the connecting rod 55 will hit the connecting rope 69. Because one end of the connecting rope 69 is fixed by the fixing rod 70, the end of the connecting rope 69 inside the fifth slot 65 connected to the second slider 64 will generate a pulling force on one end of the second slider 64. When the pulling force generated by the connecting rope 69 overcomes the third spring 66 inside the support tube 63, the second slider 64 will slide toward the connecting rod 55, and at the same time, the arc elastic sheet 67 will be brought back to the fifth slide groove 62. When the arc elastic sheet 67 returns to the fifth slide groove 62, the lumps and ink sheets shoveled up on the surface of the arc elastic sheet 67 will be scraped off by the rack 23.

[0046] When the ink-driving block 18 returns to the fourth slide groove 71, the second telescopic motor 21 is turned off, and then the second drive motor 31 is started to reverse, and the ink-driving device 16 will be driven to move in the opposite direction of the ink-driving. During the movement, the ink on the driven side will be scraped back to the other side by the scraper 17. During the ink-driving process, the ink contacts with the air in a larger area, so the water inside the ink will be released faster. When the water inside the ink is released to a certain extent, the ink will become more viscous. When the viscosity of the ink reaches a certain extent, the resistance of the scraper 17 will become larger. When the resistance received by the scraper 17 is large enough to make the scraper 17 overcome the elastic force of the first spring 51, the scraper 17 will rotate around the first rotating shaft 40 by a slight angle. During the rotation of the scraper 17, the rotating rod 47 will be driven to penetrate deeper into the third slide groove 43. When the rotating rod 47 penetrates a certain distance into the third slide groove 43, the slide plate 44 will be pushed into the third slide groove 43 by the rotating rod 47 for a certain distance. When the slide plate 44 slides into the third slide groove 43, the water outlet 45 will be driven to the middle of the water outlet trough 52, and the water inside the water outlet trough 52 will flow into the water storage tank 56 below through the water outlet hole 45. When all the ink is scraped to the other side, turn off the second drive motor 31, and then start the first telescopic motor 35. The output end of the first telescopic motor 35 brings the sliding housing 38 back to the inside of the second slide groove 37. Then start the second telescopic motor 21, and the second telescopic motor 21 drives the ink-driving block 18 to move down again. During the downward movement of the ink-driving block 18, under the action of the convex head 61 and the fourth rotating shaft 54, the water inside the water storage tank 56 will be vibrated into the ink below, and the stirring roller 19 can quickly blend the ink and water to reduce the viscosity of the ink during the forward and backward movement. During the forward and backward movement of the stirring roller 19, the rack 23 on the surface of the stirring roller 19 will also grind and crush the lumps and ink flakes scooped up by the arc-shaped elastic sheet 67.
