Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to a stop-and-go rotary screen printing machine. Background Technology

[0002] The stop-and-go rotary screen printing machine is a high-precision printing device that combines the characteristics of intermittent motion and roller structure. It is specially designed for complex patterns and multi-color overprinting. The ink is squeezed by a squeegee and transferred to the substrate through the stencil pattern of the printing plate. The ink layer is thick and the color saturation is high, making it suitable for a variety of materials.

[0003] In existing rotary screen printing machines, the installation of the printing plate is quite complicated, requiring operators to rotate multiple knobs to fix the printing plate, which is time-consuming and laborious, prolongs the printing time, and makes it inconvenient for operators to change the printing plate according to different printing needs. At the same time, after a long printing period, the ink on the printing plate dries and becomes solid, adhering to the printing plate, which is inconvenient to clean and cannot meet the needs of operators. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stop-and-go rotary drum screen printing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotary screen printing machine includes a base and a printing plate. A printing body is fixedly mounted on the base. Two sets of symmetrical mounting structures are mounted on the printing body. Each mounting structure includes two sliding openings on the printing body, with mounting blocks slidably connected to each of the two openings. One end of each mounting block is threadedly connected to a threaded rod, and both threaded rods are rotatably connected to the printing body. The printing plate has two mounting openings, with two mounting blocks slidably connected to each of the two openings. The two threaded rods are connected by a belt drive assembly. The two sets of mounting structures are connected by a gear drive assembly. A rotary motor is fixedly mounted on the printing body, and the motor shaft of the rotary motor is fixedly mounted on one of the threaded rods.

[0007] Preferably, the gear transmission assembly includes a bevel gear 1 fixedly mounted on two threaded rods, a reciprocating screw rotatably connected to the printing body, bevel gear 2 fixedly mounted at both ends of the reciprocating screw, the two bevel gear 2 meshing with the two bevel gear 1 respectively, and a scraping assembly mounted on the reciprocating screw.

[0008] Preferably, the scraping assembly includes a first movable block threaded onto a reciprocating screw, a slide rod fixedly installed on the printing body, a second movable block slidably connected to the slide rod, a lifting block slidably connected inside both the first and second movable blocks, a screw rotatably connected to one of the lifting blocks, the screw thread passing through the first movable block, and a scraping block fixedly installed on both lifting blocks.

[0009] Preferably, the printing plate has a groove, and multiple sliders are fixedly installed on the printing body, with the multiple sliders slidably connected in the groove.

[0010] Preferably, the base is equipped with a control device corresponding to the rotary motor.

[0011] Preferably, a rotating handle is fixedly installed on one end of the screw, and a rubber sleeve is fitted onto the rotating handle.

[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: by rotating a motor to drive a threaded rod to rotate, and with the cooperation of the belt transmission assembly, two threaded rods rotate simultaneously, and with the cooperation of the gear transmission assembly, four threaded rods rotate simultaneously. Therefore, four mounting blocks slide into the mounting opening of the printing plate and are squeezed, so that the printing plate can be quickly installed and removed, making it convenient for workers to replace the printing plate.

[0013] 2. The reciprocating screw rotation drives the moving block and lifting block to move on the printing plate, which allows the scraping block to scrape up solid deposits on the printing plate, facilitating subsequent cleaning work and meeting the needs of the staff.

Detailed Implementation

[0018] Reference Figures 1-3 A stop-and-go rotary screen printing machine includes a base 1 and a printing plate 2. A printing body 3 is fixedly mounted on the base 1. The base 1 and the printing body 3 are the printing parts of the stop-and-go rotary screen printing machine. The stop-and-go rotary screen printing machine is existing technology, and its structure includes a roller for conveying the printing substrate, which will not be described in detail here. Two sets of mutually symmetrical mounting structures are installed on the printing body 3. The mounting structure includes two sliding openings 4 on the printing body 3, and mounting blocks 5 are slidably connected in both sliding openings 4. One end of each mounting block 5 is threadedly connected to a threaded rod. 6. Both threaded rods 6 are rotatably connected to the printing body 3. The printing plate 2 has two mounting holes 7. Two mounting blocks 5 are slidably connected in the two mounting holes 7 respectively. The two threaded rods 6 are connected by a belt drive assembly 8. The belt drive assembly 8 consists of two pulleys and a belt body. The two sets of mounting structures are connected by a gear drive assembly. A rotary motor 9 is fixedly installed on the printing body 3. The rotary motor 9 is existing technology and can make the object connected to its motor shaft rotate. The motor shaft of the rotary motor 9 is fixedly installed on one of the threaded rods 6.

[0019] By opening the rotary motor 9, a threaded rod 6 is driven to rotate. With the cooperation of the belt drive assembly 8, two threaded rods 6 in this mounting structure rotate simultaneously. Furthermore, with the cooperation of the gear drive assembly, all four threaded rods 6 rotate simultaneously. As a result, the four mounting blocks 5 slide into the mounting openings 7 on the printing plate 2 and press against the printing plate 2, thereby quickly completing the installation of the printing plate 2. When disassembly is required, the rotary motor 9 is opened in reverse to complete the disassembly.

[0020] The gear transmission assembly includes a bevel gear 10 fixedly mounted on two threaded rods 6, a reciprocating screw 11 rotatably connected to the printing body 3, bevel gears 12 fixedly mounted at both ends of the reciprocating screw 11, the two bevel gears 12 meshing with the two bevel gears 10 respectively, and a scraping assembly mounted on the reciprocating screw 11.

[0021] The rotation of a threaded rod 6 causes the fixedly installed bevel gear 10 to rotate, which in turn drives the meshing bevel gear 12 to rotate, and causes the fixedly installed reciprocating screw 11 to rotate. As the reciprocating screw 11 rotates, the bevel gear 12 and bevel gear 10 at the other end rotate, which in turn drives the rotation of the threaded rod 6 in another mounting structure.

[0022] The scraping assembly includes a first movable block 13 threaded onto a reciprocating screw 11, a slide rod 14 fixedly mounted on the printing body 3, a second movable block 15 slidably connected to the slide rod 14, and lifting blocks 16 slidably connected inside both the first movable block 13 and the second movable block 15. A screw 17 is rotatably connected to one of the lifting blocks 16, and the screw 17 is threaded through the first movable block 13. The two lifting blocks 16 are together fixedly mounted with a scraping block 18. The overall position of the scraping assembly does not contact the positions of the brush and scraper in the printing body 3, so it will not interfere with the printing work.

[0023] During the disassembly of the printing plate 2, the rotation of the reciprocating screw 11 causes the moving block 13 to reciprocate. Due to the lifting block 16 and the scraping block 18, the moving block 2 15 is also driven to reciprocate. Therefore, the scraping block 18 scrapes up the solid deposits on the printing plate 2. The scraped-up impurities will remain on the printing plate 2, requiring further cleaning by the staff. By rotating the screw 17, the lifting block 16 can be raised and lowered, so as not to affect the removal and placement of the printing plate 2.

[0024] The printing plate 2 has a groove 19, and multiple sliders 20 are fixedly installed on the printing body 3. The multiple sliders 20 are slidably connected in the groove 19. The base 1 is equipped with a control device corresponding to the rotary motor 9. A rotating handle 21 is fixedly installed on one end of the screw 17, and a rubber sleeve is fitted on the rotating handle 21.

[0025] By sliding the slider 20 within the groove 19, the sliding of the printing plate 2 can be restricted, making it more stable to be placed in. The control device allows for faster operation of the rotary motor 9, which is beneficial for operators. By rotating the handle 21, the screw 17 can be easily rotated, thereby completing the lifting and lowering of the lifting block 16.

[0026] In this invention, the working principle is as follows: Opening the rotary motor 9 drives a threaded rod 6 to rotate. With the cooperation of the belt drive assembly 8, both threaded rods 6 in this mounting structure rotate simultaneously. The rotation of one threaded rod 6 causes the fixedly mounted bevel gear 10 to rotate, thereby driving the meshing bevel gear 12 to rotate, and causing the fixedly mounted reciprocating screw 11 to rotate. The rotation of the reciprocating screw 11 causes the bevel gear 12 and bevel gear 10 at the other end to rotate, thus driving the rotation of the threaded rod 6 in the other mounting structure. This results in all four threaded rods 6 rotating simultaneously. Therefore, the four mounting blocks 5 slide into the mounting openings 7 on the printing plate 2, and the printing... The printing plate 2 is squeezed to quickly complete the installation of the printing plate 2. When disassembly is required, the rotary motor 9 is turned in reverse to complete the disassembly. During the disassembly of the printing plate 2, the rotation of the reciprocating screw 11 will drive the moving block 13 to reciprocate. Due to the lifting block 16 and the scraping block 18, the moving block 2 15 will also reciprocate. Therefore, the scraping block 18 will scrape up the solid attachments on the printing plate 2. The scraped impurities will remain on the printing plate 2, and the staff will need to clean the printing plate 2 further. By rotating the screw 17, the lifting block 16 can be raised and lowered, so as not to affect the removal and placement of the printing plate 2.
