[0002] The fully automated screen printing device for scratch art production is an automated equipment used in scratch art manufacturing. It uses screen printing technology to precisely transfer ink onto scratch art paper to complete the printing of patterns and text. This device integrates modules for transmission, printing, and drying, enabling continuous and automated scratch art production, improving efficiency and printing quality, and reducing labor costs.

[0003] Application No. 202320133850.3 discloses a fully automatic screen printing device for scratch art. The fully automatic screen printing device for scratch art proposed in this solution uses a hydraulic push rod to raise and lower the printing table, thereby adjusting the position of the scratch art paper and improving the printing quality. The printing threaded rod drives the support rod to move smoothly, thereby moving the printing squeegee above the screen printing plate and improving the printing effect. It is simple to operate and highly practical.

[0004] The aforementioned device requires manual placement of one end of the scratch art paper onto the conveyor belt, which makes the paper prone to shifting. This shift leads to inaccurate printing pattern placement, significantly increasing the scrap rate. Furthermore, the scratch art paper is susceptible to jamming and wrinkling during transport, affecting equipment operation, reducing production efficiency, increasing production costs, and compromising print quality. Therefore, we propose a fully automatic screen printing device for scratch art production. Utility Model Content

[0034] Please see Figure 1-5 A fully automatic screen printing device for scratch art production, comprising:

[0035] Control panel 1;

[0036] Screen printing plate 3 is set at the bottom of the inside of the operating table 1.

[0037] Printing table 13 is located at the bottom of the inside of the operating table 1.

[0038] Conveyor belt 10 is installed at the bottom of the inside of the operating table 1. There are two sets of conveyor belt 10, which are symmetrically arranged on both sides of the inside of the operating table 1.

[0039] Anti-slip stripes 21, a number of anti-slip stripes 21 are set on the conveyor belt 10;

[0040] An L-shaped mounting plate 16 is fixedly connected to the inner wall of the control panel 1. A second cylinder 17 is fixedly connected to the top of the L-shaped mounting plate 16. A push plate 18 is fixedly connected to the output end of the second cylinder 17.

[0041] Anti-slip stripes 21 are set on the conveyor belt 10; the inner wall of the operating table 1 is connected to the push plate 18 through the L-shaped mounting plate 16 and the second cylinder 17.

[0042] The scratch art paper is placed above the conveyor belt 10, with one end abutting against the vertical inner wall of the L-shaped mounting plate 16. The second cylinder 17 drives the push plate 18 to move downward, pressing the paper smoothly onto the conveyor belt 10. The anti-slip stripes 21 on the surface of the conveyor belt 10 increase the friction between the paper and the conveyor belt, preventing the paper from shifting or slipping during transport. Through the cooperation of the L-shaped mounting plate 16 and the push plate 18, the scratch art paper is automatically aligned and pressed down for positioning, avoiding the shifting problem caused by manual placement. The anti-slip stripes 21 on the surface of the conveyor belt 10 further increase the friction between the paper and the conveyor belt, ensuring stable position during transport. The combination design of the slot 8 and the T-shaped block 9 allows for quick replacement of screen printing plates 3 with different patterns, shortening downtime for plate changes and improving production efficiency.

[0043] A first motor 2 is fixedly connected to the side wall of the control panel 1. A rotating drum 11 is fixedly sleeved at the output end of the first motor 2. The conveyor belt 10 is movably sleeved on the outer wall of the two sets of rotating drums 11.

[0044] After the first motor 2 is powered on, it drives the rotating drum 11 to rotate. The friction between the rotating drum 11 and the conveyor belt 10 drives the conveyor belt to run, realizing the automated transmission of the scratch paper.

[0045] The top side wall of the control panel 1 has a slot 8;

[0046] The slot 8 is matched with the screen printing plate 3;

[0047] A T-shaped block 9 is provided between the top side wall of the operating table 1 and the screen printing plate 3;

[0048] When replacing the screen printing plate 3, first remove the T-block 9, pull the old plate out of the slot 8, then push in the new plate, and finally use the T-block 9 to clamp and fix it. The cooperation between the T-block and the slot restricts the lateral movement of the printing plate.

[0049] The bottom wall inside the operating table 1 is fixedly connected to a third cylinder 20, and the printing table 13 is fixedly connected to the output end of the third cylinder 20. The printing table 13 is located between two conveyor belts 10.

[0050] When the scratch paper is conveyed to the middle of the conveyor belt 10, the piston rod of the third cylinder 20 extends, pushing the printing table 13 upward, lifting the paper upward and pressing it tightly against the bottom surface of the screen printing plate 3, forming the pressure required for printing.

[0051] A second motor 4 is fixedly connected to the top side wall of the operating table 1. A threaded rod 5 is fixedly connected to the output end of the second motor 4. The end of the threaded rod 5 away from the second motor 4 is rotatably connected to the top of the operating table 1.

[0053] A movable rod 6 is threadedly sleeved on the outer wall of the threaded rod 5, and the end of the movable rod 6 away from the threaded rod 5 is slidably sleeved on the outer wall of the limiting rod 12.

[0054] The second motor 4 drives the threaded rod 5 to rotate. The moving rod 6 moves axially along the threaded rod 5 due to the threaded transmission. At the same time, the limiting rod 12 restricts the rotation of the moving rod 6, so that it only makes linear reciprocating motion, thereby driving the printing squeegee 15 to move horizontally on the surface of the screen printing plate 3.

[0055] The bottom wall of the moving rod 6 is fixedly connected to the first cylinder 7, and the output end of the first cylinder 7 is fixedly connected to the lifting plate 14.

[0056] A printing scraper 15 is fixedly connected to the bottom of the lifting plate 14;

[0057] An ink scraper 19 is fixedly connected to the bottom of the lifting plate 14;

[0058] The first cylinder 7 drives the lifting plate 14 to rise and fall, so that the printing squeegee 15 adheres to or detaches from the screen printing plate 3; after the printing squeegee 15 completes one printing stroke, the ink squeegee 19 simultaneously spreads the remaining ink on the screen printing plate 3 in the opposite direction to prepare for the next printing.

[0059] Structural Description: Operating Table 1: As the basic support structure of the entire printing device, it provides installation positions and operating space for other components.

[0061] Screen printing plate 3: The core printing component, a template that carries the printed pattern. The pattern is transferred to the scratch paper through the ink penetration mesh. It can be installed and replaced through the slot 8 at the top of the operating table 1.

[0062] The second motor 4 is fixed to the top side wall of the operating table 1. Its output end is connected to the threaded rod 5. The motor drives the threaded rod 5 to rotate, which, together with the limit rod 12, realizes the linear reciprocating motion of the moving rod 6, thereby driving the printing squeegee 15 to perform printing operations on the screen printing plate 3.

[0063] Threaded rod 5: Connected to the output end of the second motor 4, it converts the rotational motion of the motor into the linear motion of the moving rod 6 through threaded transmission, thereby realizing the translation of the printing squeegee 15 on the screen printing plate 3.

[0064] Moving rod 6: It is threaded on the outer wall of threaded rod 5, and the other end is slidably sleeved on the outer wall of limiting rod 12. When threaded rod 5 rotates, it performs linear reciprocating motion under the guidance of limiting rod 12, which is used to drive the first cylinder 7, lifting plate 14, printing scraper 15 and other components to move.

[0065] The first cylinder 7 is fixed to the bottom wall of the moving rod 6. Its output end is connected to the lifting plate 14. The lifting plate 14 is raised and lowered by the extension and retraction of the cylinder, thereby adjusting the distance between the printing squeegee 15 and the screen printing plate 3, so as to realize the pressing printing and lifting reset actions of the printing squeegee 15.

[0066] Slot 8: Located on the top side wall of the operating table 1, matching the size of the screen printing plate 3, used for inserting and removing the screen printing plate 3, and working with the T-block 9 to achieve quick installation and fixation of the screen printing plate 3.

[0067] T-block 9: Used in conjunction with slot 8, it is inserted into the corresponding hole of slot 8 and screen printing plate 3 to fix screen printing plate 3 and prevent screen printing plate 3 from shifting during the printing process.

[0068] Conveyor belt 10: Two sets are provided, symmetrically installed on both sides inside the operating table 1, and sleeved on the outer wall of the rotating drum 11. It runs under the drive of the first motor 2 and is used to convey the scratch paper. The anti-slip stripes 21 on the surface can increase the friction with the scratch paper and prevent the paper from shifting during conveying.

[0069] Rotary drum 11: It is fixedly connected to the output end of the first motor 2 and drives the conveyor belt 10 to run through its own rotation. It is a key component for the power transmission of the conveyor belt 10.

[0070] Limiting rod 12: Fixed to the top side wall of the operating table 1, and set parallel to the threaded rod 5. Its function is to limit the movement trajectory of the moving rod 6, prevent the moving rod 6 from rotating when the threaded rod 5 rotates, and ensure that the moving rod 6 moves smoothly along a straight line.

[0071] Printing table 13: Located between two conveyor belts 10, it is fixedly connected to the output end of the third cylinder 20. Driven by the third cylinder 20, it can move up and down to lift the scratch paper and press it tightly against the bottom of the screen printing plate 3, ensuring that the paper and the printing plate are closely attached during printing.

[0072] Lifting plate 14: Connected to the output end of the first cylinder 7, it is lifted and lowered under the action of the first cylinder 7. It is used to install the printing squeegee 15 and the ink squeegee 19 and drive them to move up and down.

[0073] Printing squeegee 15: Fixed to the bottom of the lifting plate 14, it moves closely against the surface of the screen printing plate 3 under the coordinated action of the first cylinder 7 and the moving rod 6, squeezing the ink through the mesh onto the squeegee paper to complete the printing operation.

[0074] L-shaped mounting plate 16: Fixed to the inner wall of the operating table 1, used to install the second cylinder 17 and the push plate 18, providing a support structure for the positioning and pressing of the scratching paper. When the scratching paper is placed, one end can abut against the inner wall of the vertical part of the L-shaped mounting plate 16.

[0075] The second cylinder 17 is installed on the top of the L-shaped mounting plate 16. Its output end is connected to the push plate 18. The cylinder extends and retracts to drive the push plate 18 to move up and down, so as to smoothly press the scratch paper placed above the conveyor belt 10 onto the conveyor belt and avoid the paper from shifting.

[0076] Push plate 18: Connected to the output end of the second cylinder 17, it moves along the horizontal part of the L-shaped mounting plate 16 under the drive of the second cylinder 17, pressing the scratch paper onto the conveyor belt 10 to achieve precise positioning and placement of the scratch paper.

[0077] Ink scraper 19: Fixed at the bottom of the lifting plate 14 and located on one side of the printing scraper 15. When the printing scraper 15 completes the printing action and resets, it evenly spreads the ink accumulated on one end of the screen printing plate 3 onto the plate surface to prepare for the next printing.

[0078] The third cylinder 20 is fixed inside the bottom wall of the operating table 1. Its output end is connected to the printing table 13. The cylinder extends and retracts to control the lifting and lowering of the printing table 13, and adjusts the distance between the scratch paper and the screen printing plate 3 to ensure that the two are closely attached during printing.

[0079] Anti-slip stripes 21: These are set on the surface of the conveyor belt 10 to increase the friction between the conveyor belt 10 and the scratch paper, preventing the scratch paper from shifting or sliding during the conveying process and ensuring the stability of the paper transmission.

[0080] Remove the T-shaped block 9 from the slot 8 at the top of the operating table 1. Push the screen printing plate 3 with the corresponding pattern into the operating table 1 along the slot 8. Then insert the T-shaped block 9 into the slot at the top of the screen printing plate 3. Fix the screen printing plate 3 by cooperating with the slot 8. Place the scratch art paper above the two sets of conveyor belts 10, with one end of the paper abutting against the vertical inner wall of the L-shaped mounting plate 16. Start the first motor 2, whose output end drives the rotating drum 11 to rotate, and the paper moves towards the middle of the operating table 1 through the conveyor belt 10. At the same time, start the second cylinder 17, whose output end pushes the push plate 18 downward along the horizontal section of the L-shaped mounting plate 16, and presses the scratch art paper smoothly onto the conveyor belt 10. The anti-slip stripes 21 on the surface of the conveyor belt 10 increase the friction to prevent the paper from slipping. Paper offset; printing table lifting and bonding: when the scratch paper moves between the two sets of conveyor belts 10, the third cylinder 20 is activated, and its output end pushes the printing table 13 to rise, pressing the paper tightly against the bottom of the screen printing plate 3 to ensure accurate printing position; the first cylinder 7 is activated, and its output end drives the lifting plate 14 to fall, so that the printing squeegee 15 is pressed tightly against the surface of the screen printing plate 3; then the second motor 4 is activated, and its output end drives the threaded rod 5 to rotate. Under the guidance of the limit rod 12, the moving rod 6 moves back and forth along the threaded rod 5, and through the lifting plate 14, it drives the printing squeegee 15 to move at a uniform speed on the screen printing plate 3, printing ink through the mesh onto the scratch paper; after printing is completed, the ink squeegee 19 simultaneously spreads the accumulated ink evenly, preparing for the next printing.
