Description

Technical Field

[0001] This utility model relates to the field of printing technology, specifically a durable PS plate-based printing device. Background Technology

[0002] Durable PS plate-based printing equipment is a printing device that uses durable PS plates (pre-coated photosensitive plates) as the plate carrier. Its core feature is that by optimizing the plate base material, device structure, and process control, it improves the printing plate's durability (number of reprints) and printing stability, making it suitable for medium to high-volume printing needs (such as packaging, books, and commercial advertising). The PS plate base is the substrate of the printing plate, mostly made of high-purity aluminum alloy plate. After rolling and annealing, the surface flatness is ensured, reducing pressure fluctuations during printing. It is the preferred equipment for mass printing scenarios that balances cost and quality.

[0003] The existing technology still has the following shortcomings:

[0004] 1. Existing durable PS plate-based printing equipment has a problem where the substrate tends to curl after the printing process is completed. The curling is essentially a deformation caused by uneven stress and humidity on both sides of the substrate (usually various types of paper), which affects the quality of the printed product.

[0005] 2. Existing durable PS plate printing equipment lacks the function of adjusting for substrates of different sizes during the anti-curling process. Due to the different thicknesses of the substrates, the anti-curling effect cannot be guaranteed if there is no targeted adjustment function. Utility Model Content

[0006] The purpose of this invention is to provide a durable PS plate base printing device to solve the problems mentioned in the background art and overcome its technical defects.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a durable PS plate base printing device, including a support platform, two limiting grooves are opened inside the support platform, and movable mounting brackets are slidably connected inside the two limiting grooves. An adjusting screw is threadedly connected to the lower part of the movable mounting bracket, the adjusting screw passes through the bottom of the support platform and is rotatably connected thereto, and an adjusting knob is fixedly connected to the lower part of the adjusting screw.

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] like Figures 1-6 As shown, this utility model provides a technical solution:

[0029] A durable PS plate base printing device includes a support platform 1. Two limiting grooves 2 are formed inside the support platform 1. Movable mounting brackets 3 are slidably connected inside each of the two limiting grooves 2. An adjusting screw 4 is threadedly connected to the lower part of the movable mounting bracket 3. The adjusting screw 4 passes through the bottom of the support platform 1 and is rotatably connected thereto. An adjusting knob 5 is fixedly connected to the lower part of the adjusting screw 4. An anti-rollover pressure roller 1 6 is rotatably connected between the two movable mounting brackets 3. When it is necessary to adjust the distance between the anti-rollover pressure roller 1 6 and the anti-rollover pressure roller 2 15, the operator rotates the two adjusting knobs 5. During the rotation of the adjusting knobs 5, the adjusting screw 4 rotates, causing the movable mounting brackets 3 to move vertically, thereby moving the anti-rollover pressure roller 1 6 closer to or further away from the anti-rollover pressure roller 2 15, thus achieving the adjustment of the distance between them.

[0030] A housing 7 is fixedly connected to one side of the support platform 1. A servo motor 8 is fixedly connected inside the housing 7. A pulley 9 is rotatably connected to one side of the support platform 1. The pulley 9 is located inside the housing 7. The output end of the servo motor 8 is coaxially and fixedly connected to the pulley 9. A second pulley 10 is rotatably connected to the outside of the movable mounting bracket 3. An anti-winding pressure roller 6 is fixedly connected to the second pulley 10. A sliding groove 11 is provided on one side of the support platform 1. A sliding block 12 is slidably connected inside the sliding groove 11. An adjusting shaft 13 is fixedly connected to the outside of the sliding block 12. Several springs 14 are fixedly connected inside the sliding block 12. One end of each spring 14 is fixedly connected to the sliding block 12. A belt is fitted between pulley 9, pulley 10, and adjusting shaft 13. An anti-rolling pressure roller 15 is rotatably connected to the inner side of the support platform 1. When the operator starts the servo motor 8, the servo motor 8 drives pulley 9 to rotate. Pulley 9 drives pulley 10 to rotate via the belt. During the rotation of pulley 10, the anti-rolling pressure roller 6 rotates, working in conjunction with the anti-rolling pressure roller 15 to flatten the substrate and prevent curling. When the operator adjusts the distance between the anti-rolling pressure roller 6 and the anti-rolling pressure roller 15, the belt pulls the adjusting shaft 13 closer to or further away from pulley 9. The sliding block 12, which is fixedly connected to the adjusting shaft 13, is connected to the inner wall of the sliding groove 11 via springs 14. Therefore, the adjusting shaft 13 slides along the sliding groove 11, ensuring that the belt is always taut.

[0031] A base 16 is fixedly connected to one side of the support platform 1, and a printing machine body 17 is fixedly connected above the base 16. A conveyor belt 18 is installed inside the base 16. The printed substrate that has completed the printing process is transported through the conveyor belt 18 inside the base 16 to between the anti-roll pressure roller 6 and the anti-roll pressure roller 15.

[0032] The working principle of this utility model is as follows:

[0033] First, the printed substrate, having completed the printing process, is conveyed via the conveyor belt 18 inside the base 16 to the space between anti-rollover pressure roller 6 and anti-rollover pressure roller 15. Then, the operator starts the servo motor 8, which drives pulley 9 to rotate. Pulley 9, through a belt, drives pulley 10 to rotate. During rotation, pulley 10 drives anti-rollover pressure roller 6 to rotate, working in conjunction with anti-rollover pressure roller 15 to flatten the printed substrate, preventing curling, improving the quality of the printed product, and reducing the breakage rate. When it is necessary to adjust the distance between anti-rollover pressure roller 6 and anti-rollover pressure roller 15, the operator rotates two adjustment knobs 5. During rotation, the adjustment knobs 5 drive the adjustment screw 4 to rotate, which in turn moves the movable mounting bracket 3 vertically, causing anti-rollover pressure roller 6 to move closer to or further away from anti-rollover pressure roller 15, thus adjusting the distance between them to accommodate substrates of different thicknesses. When the operator adjusts the distance between the anti-winding pressure roller 16 and the anti-winding pressure roller 25, the belt will pull the adjusting shaft 13 closer to or further away from the pulley 19. The sliding block 12, which is fixedly connected to the adjusting shaft 13, is connected to the inner wall of the sliding groove 11 through the spring 14. Therefore, the adjusting shaft 13 slides along the sliding groove 11, thereby ensuring that the belt is always in a taut state and ensuring the transmission effect of the belt.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
