DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2 As shown, a glass screen printing device includes a connecting frame 1, two cylinders 2 are fixedly arranged on the left and right sides above the surface of the connecting frame 1, the lower end of the cylinder 2 is fixedly arranged with the same movable frame 3, slots 4 are opened on the opposite sides of the longitudinal frame surface of the movable frame 3, and blocks 5 are slidably arranged through the front ends of the inner surfaces of the slots 4, a pull rod 6 is fixedly installed on one end of the block 5 close to the outer side of the movable frame 3, a telescopic spring 7 is fixedly installed on the surface of the pull rod 6 close to the movable frame 3, and one end of the telescopic spring 7 is fixedly connected to the movable frame 3, an insert block 8 is slidably arranged inside the slot 4 at the rear side of the stop block 5, and a screen body 9 is fixedly installed in the middle of the opposite side of the insert block 8.

[0024] Furthermore, after the inserting block 8 is inserted into the slot 4 , the entire wire mesh body 9 can be limited in the up, down, left, and right directions to prevent the wire mesh body 9 from vibrating and deviating.

[0025] Furthermore, the front side of the front of the block 5 is set as an inclined surface, so that when the plug block 8 is inserted, the block 5 can be pushed to move together. The rear side of the block 5 is a right-angled surface. After the plug block 8 is fully inserted, the right-angled surface of the block 5 cannot push the block 5 to move together, and then cooperate with the rear end of the slot body of the slot 4 so that the wire mesh body 9 can be completely stably and firmly installed on the movable frame 3.

[0026] Furthermore, the pull rod 6 is connected to the stopper 5, and the retraction movement of the stopper 5 can be controlled by pulling the pull rod 6, so that the wire mesh body 9 can be quickly disassembled.

[0027] like Figure 1 and Figure 3 As shown, collecting troughs 10 are fixedly installed at the rear end of the middle of the longitudinal frames on both sides of the movable frame 3, and the collecting troughs 10 and the screen body 9 are located in the same horizontal plane, and a screw rod 11 and a guide rod 12 are sequentially arranged from left to right in the middle of the opposite side of the front and rear end transverse frames of the movable frame 3, and the screw rod 11 is rotatably connected to the movable frame 3, and the guide rod 12 is fixedly connected to the movable frame 3, the screw rod 11 is driven to rotate by a rotating motor, and the surfaces of the screw rod 11 and the guide rod 12 are penetrated by the same movable plate 13, and the movable plate 13 is threadedly connected to the screw rod 11 and slidably connected to the guide rod 12, a pressure block 14 is fixedly installed at the front end below the surface of the movable plate 13, and a thrust spring 15 is fixedly installed on the rear side below the surface of the movable plate 13, and a scraper 16 is fixedly arranged at the bottom end of the thrust spring 15.

[0028] Furthermore, the screw rod 11 is rotated by the rotary motor, and the guide rod 12 limits the movable plate 13, which is then pushed by the thread to move, driving the pressing block 14 to press and move against the surface of the screen body 9 to print on the glass.

[0029] Furthermore, the scraper 16 will also follow the moving plate 13 to move in contact with the surface of the screen body 9, push and scrape off excess ink on the surface of the screen body 9, so that only the amount of ink required for a single printing will adhere to the surface of the screen body 9. The excess ink will be scraped backwards and pushed into the collecting tank 10 by the scraper 16 to collect the remaining ink.

[0030] Furthermore, by utilizing the elasticity of the thrust spring 15 , the scraper 16 itself can be adjusted to move up and down, thereby avoiding the situation in which the screen body 9 is broken due to excessive buckling during the scraping and sliding process.

[0031] like Figure 1 and Figure 4 As shown, a placing table 17 is fixedly provided in the middle of the bottom end of the connecting frame 1, and "L"-shaped limiting plates 18 are fixedly installed at the four corners above the surface of the placing table 17, a suction cup 19 is fixedly installed in the middle above the surface of the placing table 17, and a vacuum machine 20 is fixedly provided in the middle below the surface of the placing table 17, and the air inlet end of the vacuum machine 20 is connected to a conveying pipe 21, which passes through the placing table 17 and is connected to the inside of the suction cup 19.

[0032] Furthermore, the limiting plates 18 enable the four corners of the glass to be precisely positioned, ensuring that the glass plate and the printing surface of the screen body 9 are precisely aligned.

[0033] Furthermore, the vacuum machine 20 extracts the air in the suction cup 19 through the suction of the conveying pipe 21, and then the glass is stably placed on the placement table 17 under atmospheric pressure, effectively preventing the glass plate from shaking and deviating during the printing process.

[0034] Working principle: When using the glass screen printing device, first, insert the screen body 9 into the slot 4 through the plug block 8, use the inclined surface of the block 5 to push the block 5 to move outward and converge into the front end inner wall of the slot 4, and push the pull rod 6 to extend and pull the telescopic spring 7. After the plug block 8 is fully inserted, under the rebound force of the telescopic spring 7, the pull rod 6 will be pulled to push the block 5 to reset and insert it into the front end groove body of the slot 4, thereby blocking the slot 4, so that the plug block 8 can carry the screen body 9 to be installed stably, firmly and quickly, and then the limiting plate 18 is used to accurately position the four corners of the glass to ensure that the glass plate and the printing surface of the screen body 9 are accurately aligned. At this time, the bottom of the glass will fit the suction cup 19, and then, start the vacuum machine 20, extract the air in the suction cup 19 through the conveying pipe 21, and use atmospheric pressure to firmly fix the glass plate on the placement table 17, and then Finally, start the cylinder 2 to push the movable frame 3 downward so that the screen body 9 is attached to the surface of the glass plate, and the screw rod 11 rotates. Under the limit of the guide rod 12, the movable plate 13 is driven to drive the pressure block 14 to fit the surface of the screen body 9 and squeeze and move to print on the glass, and the scraper 16 will also follow the movable plate 13 to fit the surface of the screen body 9 and push and scrape off the excess ink on the surface of the screen body 9, so that the surface of the screen body 9 will only adhere to the amount of ink required for a single printing, and the excess ink will be scraped backward and pushed into the collecting tank 10 with the scraper 16. After multiple printings, pull the pull rod 6 for the second time, and pull the stopper 5 to converge for the second time into the front end inner wall of the slot 4, and then reopen the slot 4, pull the screen body 9 through the plug block 8 to slide out along the slot 4, and then it can be disassembled for cleaning and replacement. This is the working principle of the glass screen printing device.
