Description

Technical Field

[0001] The utility model belongs to the technical field of printing, and particularly relates to a pressure adjustable structure for ink printing. Background Technique

[0002] Pressure adjustment in ink printing is a key step to ensure printing quality; appropriate pressure can ensure uniform transfer of ink and clear printing effect; in a double-roller printing system, the pressure between the inking roller and the metal anilox roller determines the amount of ink on the anilox roller, and the pressure of the ink delivery device affects the ink transfer between the metal anilox roller and the printing plate roller; when adjusting the printing pressure, it should start from the last ink color and be gradually adjusted until all ink colors are accurately registered; the adjustment of printing pressure usually involves changing the center distance between the rollers or adjusting the lining thickness of the rollers; during the adjustment process, the minimum pressure should be used to complete the printing to reduce wear on the printing plate and blanket and extend the service life of the machine; in actual operation, the pressure should be determined according to the characteristics of the product and the size of the printing area; for example, halftone products may require greater pressure, while large-character and solid-color products relatively require less pressure; at the same time, the adjustment of printing pressure should also consider the type of paper and changes in temperature and humidity in the printing environment.

[0003] Currently, when using a double-roller printing machine, in order to achieve a better printing effect, it is necessary to adjust the pressure between the printing rollers. However, the distance between the two printing rollers of the existing double-roller printing machine is generally fixed, and the installation position of the printing rollers will become loose after long-term use, affecting the printing quality. Based on this, a pressure adjustable structure for ink printing is proposed. Summary of the Utility Model

[0019] Embodiment

[0020] As Figures 1-3 shown, a pressure adjustable structure for ink printing includes a box body 1 and an ink storage box 2. A cylinder 7 is installed on the top of the box body 1. The output end of the cylinder 7 is fixedly connected to a lifting frame 8. One side of the lifting frame 8 is fixedly connected to a motor 10. The output end of the motor 10 is fixedly connected to an upper printing roller 11. The upper printing roller 11 is rotatably connected inside the lifting frame 8. A lower printing roller 6 is installed directly below the upper printing roller 11 in the box body 1. The upper printing roller 11 and the lower printing roller 6 are adapted to each other. The inner top of the lifting frame 8 is fixedly connected to an ink coating box 13. The middle position at the bottom of the ink coating box 13 is fixedly connected to an ink coating cotton 14. The top of the lifting frame 8 is fixedly connected to a bellows 12. The bellows 12 is internally communicated with the ink coating box 13 and internally communicated with the ink storage box 2. An electric control valve is installed at the part where the bellows 12 is communicated with the ink storage box 2. The top of the ink storage box 2 is fixedly connected to an ink filling pipe 3. A sealing plug is installed at the top of the ink filling pipe 3. The ink coating cotton 14 is arranged on the top of the upper printing roller 11 and is adapted to the upper printing roller 11. Through grooves 9 are opened on both the front and rear sides of the box body 1. The lifting frame 8 is slidably connected inside the through grooves 9. Conveying holes 20 are opened on both the front and rear sides of the box body 1. Conveying plates 4 are fixedly connected to both the front and rear sides of the box body 1. The conveying plates 4 are flush with the conveying holes 20. Conveying rollers 5 are rotatably connected inside the conveying plates 4.

[0021] In use, open the sealing plug and add ink into the ink storage box 2 through the ink filling tube 3. When printing, place the product to be printed on the conveying plate 4 at the front side of the box body 1, convey it through the conveying roller 5 to between the upper printing roller 11 and the lower printing roller 6, and make the product pass through the conveying plate 4 at the rear side of the box body 1. Then, the air cylinder 7 can be started to push the lifting frame 8 to move downward, adjust the distance between the upper printing roller 11 and the lower printing roller 6, and adjust the pressure of the upper printing roller 11 and the lower printing roller 6 on the product. When the required pressure is reached, the motor 10 can be started to make the upper printing roller 11 rotate, and the electromagnetic valve is opened, so that the ink in the ink storage box 2 enters the ink coating box 13 through the corrugated pipe 12, moistens the ink coating cotton 14. When the upper printing roller 11 rotates past the ink coating cotton 14, the ink coating cotton 14 will smear the ink on the upper printing roller 11, and the upper printing roller 11 will print the product;

[0022] The adjustment of the distance between the upper printing roller 11 and the lower printing roller 6 is realized, so that the adjustable structure can be applied to the printing of products of different sizes, and the printing pressure can be adjusted under the action of the air cylinder 7 to ensure the printing effect. In addition, when adjusting the distance and the printing pressure, the corrugated pipe 12 provided can ensure that the ink storage box 2 always injects ink into the ink coating box 13, further ensuring the printing quality.

[0023] Such as Figure 1 、 Figure 2 and Figure 4 As shown, a sliding groove 15 is formed at the end part of the lifting frame 8 extending out of the box body 1. A sliding plate 16 is slidably connected in the sliding groove 15. A telescopic rod 17 and a connecting spring 18 are fixedly connected to the top of the sliding plate 16. The connecting spring 18 is sleeved on the telescopic rod 17. The top of the telescopic rod 17 and the connecting spring 18 is fixedly connected to the inner top of the sliding groove 15. A guiding roller 19 is rotatably connected to the adjacent side of the sliding plate 16. The guiding roller 19 is arranged opposite to the conveying roller 5, and the bottom of the guiding roller 19 is lower than the bottom of the upper printing roller 11.

[0024] In use, when the lifting frame 8 moves downward, the lifting frame 8 will drive the guiding roller 19 to move downward and press the product. During the process of reaching the required distance and pressure between the upper printing roller 11 and the lower printing roller 6, the guiding roller 19 will push the sliding plate 16 to slide upward under the action of the product, squeeze the telescopic rod 17 and the connecting spring 18, so that the guiding roller 19 squeezes and clamps the product through the conveying roller 5, preventing the product from gathering towards the upper printing roller 11 due to the change of the pressure when the upper printing roller 11 and the lower printing roller 6 print the product, resulting in an increase in the contact area between the upper printing roller 11 and the product and affecting the printing quality of the product;

[0025] It ensures the effective limitation of the product position during the printing of the product, thus ensuring the uniform transfer of ink and clear printing effect after the product is printed, and ensuring the printing quality of the product.

[0026] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
