Description

Technical Field

[0001] This invention relates to the field of UV ink screen printing technology, and in particular to a UV ink screen printing apparatus and its usage method. Background Technology

[0002] UV ink screen printing equipment is a high-efficiency and environmentally friendly printing device that combines screen printing technology with UV curing technology. Through an automated control system, this equipment can achieve high-precision, high-volume screen printing.

[0003] A novel squeegee assembly disclosed in Chinese Invention Patent Application Publication No. CN223832625U, while reducing maintenance difficulty and cost, keeping workpieces clean, reducing cleaning work, and ultimately improving production efficiency and product quality, suffers from several drawbacks. The squeegee lacks components to prevent ink buildup on the blade, requiring operators to frequently stop the machine to remove ink lumps from the blade back. This increases the labor intensity of manual maintenance and wastes solvents for cleaning the squeegee and screen, thus reducing the company's production efficiency and overall economic benefits. Furthermore, the squeegee primarily uses manual application for ink placement, which may result in ink being applied to non-processing areas, rendering the ink unusable and wasting UV ink, thus increasing production costs. Therefore, this application provides a UV ink screen printing device and its usage method to meet these needs. Summary of the Invention

[0012] Preferably, the ink delivery module includes an ink cartridge, a vertical plate on the back of the ink cartridge, the ink cartridge being threadedly connected to the vertical plate via an ink cartridge bolt, an ink filling end fixedly connected to the top of the ink cartridge, a screw cap threadedly connected to the surface of the ink filling end, a water pump on the back of the ink cartridge, the water pump being threadedly connected to the ink cartridge via a water pump bolt, and the water pump and the circular hole being mutually compatible.

[0014] A method of using a UV ink screen printing apparatus includes the following steps: Step 1: The operator can complete the entire ink feeding and printing process by operating the main unit. Place the object to be printed on top of the object placement plate, then activate the fourth cylinder to push the fourth push rod to press the screen onto the top of the object. Activate the ink feeding module to deliver ink to the core processing area in the middle of the screen. Then activate the second cylinder to drive the second push rod so that the squeegee can press onto the ink. Activate the third cylinder to drive the third push rod so that the first and second sliders can move horizontally inside the slide rail, thereby causing the squeegee to spread the ink evenly. After the first slider reaches the end of the slide rail, activate the first cylinder to drive the first push rod downward, thereby causing the doctor blade module to move downward onto the ink. Then restart the third cylinder so that the first and second sliders can return to their original positions, and the second cylinder is also activated simultaneously to lift the squeegee. At this time, the doctor blade module scrapes the ink downward, allowing the ink to be printed onto the object. Step Two: The external air pipe connects to specially supplied industrial gas that has undergone filtering treatment. The air pump pressurizes the incoming gas and then transmits it through the outlet to the bellows, finally ejecting it through the nozzle. The ejected gas forms a gas curtain, preventing ink from accumulating on the back of the doctor blade. Before this, the operator needs to turn on the power to the external power cord, allowing current to flow into the voltage regulator for voltage stabilization, and then powering the laser emitter. This enables the laser emitter to emit laser light, which is emitted from the laser emitting head, with a laser beam emitted from both sides of the nozzle. Two lasers simulate the position of the gas curtain being sprayed onto the back of the scraper. Then, based on the position of the gas curtain simulated by the lasers, the long rod bolts are loosened to adjust the length of the bellows. The cooperation of the rod sleeve and the track rod can limit the movement trajectory of the bellows. After confirming that the gas curtain is tightly attached to the back of the scraper, the long rod bolts are tightened again to fix the adjusted bellows. The gas curtain sprayed from the adjusted nozzle can then be sprayed tightly onto the back of the scraper, isolating the ink from the back of the scraper and thus reducing the possibility of ink accumulating on the back of the scraper. Step 3: Ink is injected into the ink cartridge through the ink filling end, and then the screw cap is rotated onto the surface of the ink filling end. The ink in the ink cartridge can be drawn out into the horizontal water pipe, and then the ink will enter the vertical water pipe. The ink in the vertical water pipe is divided into the first short pipe. Part of the ink flows out through the first ink outlet pipe, while the other part of the ink enters the second short pipe and then flows out through the second ink outlet pipe. Finally, all the ink flows into the core processing area of ​​the screen.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, the doctor blade module allows the device to spray an air curtain that adheres tightly to the blade, thus preventing ink from sticking to the blade. This inhibits ink accumulation on the back of the blade to a certain extent, enabling the equipment to adapt to longer continuous production cycles. It significantly reduces the number of times operators need to stop the machine frequently to remove ink lumps from the back of the blade. This not only reduces the labor intensity of manual maintenance but also reduces the waste of solvent consumables for cleaning the doctor blade and screen, thereby helping to improve the company's production efficiency and overall economic benefits.

[0016] By setting up an ink delivery module, the device can use precisely controlled jetting force to release ink in a targeted and quantitative manner to the core processing area. This "on-demand ink supply" method ensures that the ink is distributed only within the effective printing area, which can reduce the amount of ineffective ink residue in non-processing areas to a certain extent, thereby reducing the waste of UV ink and lowering production costs.

[0017] In summary, this invention has the advantages of suppressing ink buildup on the blade, reducing downtime for removing lumps from the blade back, reducing labor intensity for manual maintenance and waste of cleaning solvents, increasing enterprise production efficiency and overall economic benefits, accurately delivering ink to the core processing area, fully utilizing the ink, reducing UV ink waste, and lowering production costs.

A track rod 105, a first threaded sleeve 106 and an air outlet 107 are fixedly connected to the side of the air pump 102 from front to back.

[0032] One end of the track rod 105 is threadedly connected to a limit plate 108. The surface of the track rod 105 is provided with a rod sleeve 109. A first thin post 110 is fixedly connected to the surface of the rod sleeve 109. A second threaded sleeve 111 is fixedly connected to one end of the first thin post 110. A long bolt 112 is threadedly connected inside the first threaded sleeve 106 and the second threaded sleeve 111. A second thin post 113 is fixedly connected to the surface of the second threaded sleeve 111.

[0033] A corrugated pipe 114 is fixedly connected to one end of the second thin column 113. A rigid air pipe 115 is fixedly connected to one end of the corrugated pipe 114. A jet nozzle 116 is fixedly connected to the bottom of the rigid air pipe 115. Laser emitters 117 are provided on both sides of the jet nozzle 116. The jet nozzle 116 is threadedly connected to the laser emitter 117 via laser emitter bolts.

[0034] A voltage regulator 118 is fixedly connected to the top of the laser emitter 117. An external wire 119 is provided on the top of the voltage regulator 118. A laser emitting head 120 is provided at the bottom of the laser emitter 117.

[0035] The T-shaped plate 101 is installed at the bottom of the first push rod 2. The external air pipe 103 is installed on the air pump 102. The air pump 102 is fixed to the top of the scraper 104 by the air pump bolt. The track rod 105, the first threaded sleeve 106, and the air outlet 107 are welded to the side of the air pump 102. The limiting plate 108 is screwed to the end of the track rod 105. The rod sleeve 109 is fitted onto the surface of the track rod 105. The first thin post 110 is welded between the rod sleeve 109 and the second threaded sleeve 111. The long rod bolt 112 is used for installation. The first threaded sleeve 106 and the second threaded sleeve 111 are installed inside each other. The second thin column 113 is welded between the second threaded sleeve 111 and the bellows 114. The rigid air pipe 115 is welded between the bellows 114 and the nozzle 116. The laser emitter 117 is fixed to both sides of the nozzle 116 by laser emitter bolts. The voltage regulator 118 is welded to the laser emitter 117. The external wire 119 is installed on the voltage regulator 118. The laser emitter head 120 and the laser emitter 117 are connected as a whole.

[0036] The external air pipe 103 is connected to specially supplied industrial gas that has undergone filtration treatment. The air pump 102 pressurizes the incoming gas and then transmits it through the outlet 107 to the bellows 114, and finally ejects it through the nozzle 116. The ejected gas can form a gas curtain to prevent ink from accumulating on the back of the doctor blade 104. Before this, the operator needs to turn on the power supply of the external power cord 119 so that the current can enter the voltage regulator 118 for voltage regulation, and then power the laser emitter 117 so that the laser emitter 117 can emit laser. The laser is emitted from the laser emitting head 120, and two lasers are emitted from both sides of the nozzle 116. The laser simulates the position of the gas curtain being sprayed onto the back of the scraper 104. Then, based on the position of the gas curtain simulated by the laser, the long rod bolt 112 is loosened, thereby adjusting the length of the bellows 114. The cooperation of the sleeve 109 and the track rod 105 can restrict the movement trajectory of the bellows 114. After confirming that the gas curtain is tightly attached to the back of the scraper 104, the long rod bolt 112 is tightened again, thereby fixing the adjusted bellows 114. The gas curtain sprayed from the adjusted nozzle 116 can then be sprayed tightly onto the back of the scraper 104, isolating the ink from the back of the scraper 104, thereby reducing the possibility of ink accumulating on the back of the scraper 104.

[0037] By using the doctor blade module 1, the device can spray an air curtain that adheres tightly to the blade, thus preventing ink from sticking to the blade. This inhibits ink accumulation on the back of the blade to a certain extent, allowing the equipment to adapt to longer continuous production cycles. It also significantly reduces the number of times operators need to stop the machine to remove ink lumps from the back of the blade. This not only reduces the labor intensity of manual maintenance but also reduces the waste of solvent consumables for cleaning the doctor blade and screen, thereby helping to improve the company's production efficiency and overall economic benefits.

[0038] like Figures 10 to 12 As shown, in this embodiment, the ink delivery module 18 includes an ink cartridge 1801. A vertical plate 17 is provided on the back of the ink cartridge 1801. The ink cartridge 1801 is threadedly connected to the vertical plate 17 via an ink cartridge bolt. An ink filling end 1802 is fixedly connected to the top of the ink cartridge 1801. A screw cap 1803 is threadedly connected to the surface of the ink filling end 1802. A water pump 1804 is provided on the back of the ink cartridge 1801. The water pump 1804 is threadedly connected to the ink cartridge 1801 via a water pump bolt. The water pump 1804 and the circular hole are mutually compatible.

[0039] One end of the water pump 1804 is threadedly connected to a horizontal water pipe 1805. One end of the horizontal water pipe 1805 is fixedly connected to a vertical water pipe 1806. A first short pipe 1807 is fixedly connected to the surface of the vertical water pipe 1806. One end of the first short pipe 1807 is fixedly connected to a first ink outlet pipe 1808. A second short pipe 1809 is fixedly connected to the surface of the first ink outlet pipe 1808. One end of the second short pipe 1809 is fixedly connected to a second ink outlet pipe 1810.

[0040] The ink cartridge 1801 is fixed to the vertical plate 17 by ink cartridge bolts. The ink filling end 1802 is welded to the top of the ink cartridge 1801. The screw cap 1803 is screwed onto the surface of the ink filling end 1802. The water pump 1804 is fixed to the ink cartridge 1801 by water pump bolts. The horizontal water pipe 1805 is installed on the water pump 1804. The vertical water pipe 1806 and the horizontal water pipe 1805 are integrally formed. The first short pipe 1807 is welded between the vertical water pipe 1806 and the first ink outlet pipe 1808. The second short pipe 1809 is welded between the first ink outlet pipe 1808 and the second ink outlet pipe 1810.

[0041] Ink is injected into ink cartridge 1801 through ink filling end 1802, and then the screw cap 1803 is rotated onto the surface of ink filling end 1802. The ink in ink cartridge 1801 can be drawn out through ink cartridge 1801 into horizontal water pipe 1805, and then the ink will enter vertical water pipe 1806. The ink in vertical water pipe 1806 is diverted into first short pipe 1807. Part of the ink flows out through first ink outlet pipe 1808, while the other part of the ink enters second short pipe 1809 and then flows out through second ink outlet pipe 1810. Finally, all the ink flows into the core processing area of ​​screen 22.

[0042] By setting up the ink delivery module 18, the device can use precisely controlled jetting force to release ink in a targeted and quantitative manner to the core processing area. This "on-demand ink supply" method ensures that the ink is distributed only within the effective printing range, which can reduce the amount of ineffective ink residue in non-processing areas to a certain extent, thereby reducing the waste of UV ink and lowering production costs.

[0043] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0044] A method of using a UV ink screen printing apparatus includes the following steps: Step 1: The operator can complete the entire ink feeding and printing process by operating the main unit 24. Place the object to be printed on top of the object placement plate 23, then activate the fourth cylinder 20 to push the fourth push rod 21, thereby pressing the screen 22 onto the top of the object to be printed. Activate the ink feeding module 18 to deliver ink to the central core processing area of ​​the screen 22. Then, activate the second cylinder 11 to drive the second push rod 12 so that the smear plate 13 can press onto the ink. Finally, activate the third cylinder 15 to drive the third push rod 14 to move the first slider 6 and the second slider 8... The slide can move horizontally inside the slide rail 16, thereby driving the smear plate 13 to spread the ink evenly. After the first slider 6 reaches the end of the slide rail 16, the first cylinder 3 is activated to drive the first push rod 2 to move downward, thereby causing the scraper module 1 to move downward onto the ink. Then the third cylinder 15 is restarted, so that the first slider 6 and the second slider 8 can return to their original positions. The second cylinder 11 is also activated simultaneously to lift the smear plate 13. At this time, the scraper module 1 scrapes the ink downward, so that the ink can be printed onto the object to be printed. Step 2: The external air pipe 103 is connected to specially supplied industrial gas that has undergone filtering treatment. The air pump 102 pressurizes the incoming gas and then transmits it through the outlet 107 to the bellows 114, and finally ejects it through the nozzle 116. The ejected gas can form a gas curtain to prevent ink from accumulating on the back of the doctor blade 104. Before this, the operator needs to turn on the power supply of the external power cord 119 so that the current can enter the voltage regulator 118 for voltage regulation, and then power the laser emitter 117, so that the laser emitter 117 can emit laser light. The laser light is emitted from the laser emitting head 120, and one laser light is emitted from each side of the nozzle 116, for a total of Two lasers simulate the position of the gas curtain being sprayed onto the back of the scraper 104. Then, according to the position of the gas curtain simulated by the laser, the long rod bolt 112 is unscrewed, thereby adjusting the length of the bellows 114. The cooperation of the rod sleeve 109 and the track rod 105 can limit the movement trajectory of the bellows 114. After confirming that the gas curtain is tightly attached to the back of the scraper 104, the long rod bolt 112 is tightened again, thereby fixing the adjusted bellows 114. The gas curtain sprayed from the adjusted nozzle 116 can be sprayed tightly onto the back of the scraper 104, isolating the ink from the back of the scraper 104, thereby reducing the possibility of ink accumulating on the back of the scraper 104. Step 3: Ink is injected into ink cartridge 1801 through ink filling end 1802. Then, the screw cap 1803 is rotated and placed on the surface of ink filling end 1802. The ink in ink cartridge 1801 can be drawn out through ink cartridge 1801 into horizontal water pipe 1805. Then the ink will enter vertical water pipe 1806. The ink in vertical water pipe 1806 is diverted into first short pipe 1807. Part of the ink flows out through first ink outlet pipe 1808, while the other part of the ink enters second short pipe 1809 and then flows out through second ink outlet pipe 1810. Finally, all the ink flows into the core processing area of ​​screen 22.

[0045] The technical solution provided by this invention: The operator can complete the entire ink feeding and printing process by operating the main unit 24. The object to be printed is placed on top of the object placement plate 23. Then, the fourth cylinder 20 is activated to push the fourth push rod 21, thereby pressing the screen 22 onto the top of the object to be printed. The ink feeding module 18 is activated to deliver ink to the central core processing area of ​​the screen 22. Then, the second cylinder 11 is activated to drive the second push rod 12, allowing the smear plate 13 to press onto the ink. Then, the third cylinder 15 is activated to drive the third push rod 14, allowing the first slider 6 and the second slider 8 to advance horizontally inside the slide rail 16, thereby causing the smear plate 13 to spread the ink evenly. After the first slider 6 reaches the end of the slide rail 16, the first... Cylinder 3 drives the first push rod 2 downward, causing the doctor blade module 1 to move downward onto the ink. Then, the third cylinder 15 is restarted, allowing the first slider 6 and the second slider 8 to return to their original positions. Simultaneously, the second cylinder 11 is also activated, lifting the squeegee 13. At this time, the doctor blade module 1 scrapes the ink downward, allowing the ink to be printed onto the object to be printed. The external air pipe 103 is connected to specially supplied industrial gas that has undergone filtration treatment. The air pump 102 pressurizes the incoming gas and then transmits it through the air outlet 107 to the bellows 114, and finally sprays it out through the nozzle 116. The sprayed gas can form an air curtain to prevent ink from accumulating on the back of the doctor blade 104. Before this, the operator needs to... First, turn on the power supply to the external power cord 119 so that the current can enter the voltage regulator 118 for voltage regulation. Then, power is supplied to the laser emitter 117, enabling it to emit lasers. The lasers are emitted from the laser emitter head 120, with one laser beam emitted from each side of the nozzle 116, for a total of two laser beams. This simulates the position of the gas curtain being sprayed onto the back of the scraper 104. Then, according to the position of the gas curtain simulated by the laser, loosen the long rod bolt 112 to adjust the length of the bellows 114. The cooperation of the rod sleeve 109 and the track rod 105 restricts the movement trajectory of the bellows 114. After confirming that the gas curtain is tightly attached to the back of the scraper 104, loosen the long rod bolt 112 again. The air is tightened to secure the adjusted corrugated pipe 114. The gas curtain ejected from the adjusted nozzle 116 can then be sprayed tightly against the back of the scraper 104, isolating the ink from the back of the scraper 104 and reducing the possibility of ink accumulation on the back of the scraper 104. The ink is injected into the ink cartridge 1801 through the ink filling end 1802, and then the screw cap 1803 is rotated onto the surface of the ink filling end 1802. The ink in the ink cartridge 1801 can be drawn out through the ink cartridge 1801 into the horizontal water pipe 1805, and then the ink will enter the vertical water pipe 1806. The ink in the vertical water pipe 1806 is then diverted into the first short pipe 1807, and a portion of the ink flows out through the first ink outlet pipe 1808.The remaining ink enters the second short tube 1809 and flows out through the second ink outlet tube 1810, ultimately concentrating entirely in the core processing area of ​​the screen 22.

Place the object to be printed on top of the object placement plate (23), then start the fourth cylinder (20) to push the fourth push rod (21) to press the screen (22) onto the top of the object to be printed. Start the ink feeding module (18) to deliver the ink to the central core processing area of ​​the screen (22). Then start the second cylinder (11) to drive the second push rod (12) so that the smear plate (13) can press onto the ink. Then start the third cylinder (15) to drive the third push rod (14) so ​​that the first slider (6) and the second slider (8) can press onto the ink. The first slider (6) can move horizontally inside the slide rail (16), thereby driving the squeegee (13) to spread the ink evenly. Then, after the first slider (6) reaches the end of the slide rail (16), the first cylinder (3) is started to drive the first push rod (2) to move downward, thereby causing the scraper module (1) to move downward onto the ink. Then, the third cylinder (15) is restarted, so that the first slider (6) and the second slider (8) can return to their original positions, and the second cylinder (11) is also started synchronously to lift the squeegee (13).

The sprayed gas can form a gas curtain to prevent ink from accumulating on the back of the doctor blade (104). Before this, the operator needs to turn on the power of the external power cord (119) so that the current can enter the voltage regulator (118) for voltage regulation and then power the laser emitter (117), so that the laser emitter (117) can emit laser.

The use of the rod sleeve (109) and the track rod (105) can limit the movement trajectory of the bellows (114). After confirming that the gas curtain is close to the back of the scraper (104), the long rod bolt (112) is tightened again, thereby fixing the adjusted bellows (114). The gas curtain sprayed from the adjusted nozzle (116) can be sprayed close to the back of the scraper (104), isolating the ink from the back of the scraper (104), thereby reducing the possibility of ink accumulating on the back of the scraper (104). Step 3: The ink is injected into the ink cartridge (1801) through the ink filling end (1802), and then the screw cap (1803) is rotated and placed on the surface of the ink filling end (1802). The ink in the ink cartridge (1801) can be drawn out through the ink cartridge (1801) into the horizontal water pipe (1805), and then the ink will enter the vertical water pipe (1806).
