[0002] Printing equipment refers to the technology of batch copying the original content by making text, pictures, photos, anti-counterfeiting and other images into printing plates, and then printing ink and pressurizing the plates onto the surface of materials such as paper, textiles, plastic products, leather, ceramics, metals and wood products. It is collectively called printing, and is the process of transferring the content to the substrate through printing machinery and special inks. A printing press is a machine for printing text and images. Modern printing presses are generally composed of plate mounting, inking, embossing, and conveying mechanisms. The general working principle is to place the printed material on the conveying device, and then convey it to the bottom of the printing roller for rolling printing in sequence.

[0003] During the printing process, the distance between the printing roller and the printed product needs to be adjusted according to the different thicknesses of the printed product. Precise control is required during the adjustment process to prevent the printing roller from crushing the printed product. Most existing adjustment devices adjust the distance of the printing roller through a screw rod. However, the printing equipment will vibrate during the production process, and the screw rod does not have a self-locking function, which may cause the screw rod to rotate on its own. The printing roller may move during operation, causing damage to the printed product and resulting in defective products. To this end, we provide a printing roller adjustment device for printing equipment to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a printing roller adjustment device for printing equipment, comprising two lifting frames 1 and a supporting frame 2, the inner walls of the two lifting frames 1 are slidably connected with sliders 3, the lifting frames 1 allow the sliders 3 to have a sliding distance, the sliders 3 can drive the printing roller body 4 to move, the printing roller body 4 is arranged on the outside of the slider 3, the printed product is printed by the printing roller body 4, the inner side of the slider 3 is threadedly connected with a lead screw 5, the rotation of the lead screw 5 can provide power for the sliding of the slider 3, one end of the lead screw 5 is fixedly connected with a first bevel gear 6, the outer surface of the first bevel gear 6 is meshedly connected with a second bevel gear 7, the inner wall of the second bevel gear 7 is fixedly connected with a rotating shaft 8, the second bevel gear 7 is driven to rotate by the rotation of the rotating shaft 8, and the first bevel gear 6 is driven to rotate after the second bevel gear 7 rotates.

[0025] The outer surface of the rotating shaft 8 is rotatably connected to the inner side of the support frame 2, the lower surface of the support frame 2 is fixedly connected to the upper surface of the lifting frame 1, the outer surface of the support frame 2 is fixedly connected with a sleeve 9, the inner wall of the sleeve 9 is slidably connected with a sleeve 10, the inner side of the sleeve 9 is provided with a slide groove 18, the outer surface of the sleeve 10 is fixedly connected with a guide rail 19, the outer surface of the guide rail 19 is slidably connected to the inner wall of the slide groove 18. In order to prevent the sleeve 10 from rotating when sliding into the sleeve 9 again, the guide rail 19 is guided to slide back and forth by the slide groove 18, and the guide rail 19 can limit the rotation of the sleeve 10. A spring 11 is arranged inside the sleeve 10, one end of the spring 11 is fixedly connected to the inner wall of the sleeve 9, and the other end of the spring 11 is fixedly connected to the inner wall of the sleeve 10. The sleeve 9 provides a supporting force to the spring 11 to support the elastic output of the spring 11. The sleeve 10 is located outside the sleeve 9 One end of the part is fixedly connected with a first chuck 12, and the outer surface of the first chuck 12 is in sliding contact with a second chuck 13, and the inner wall of the second chuck 13 is fixedly connected to the outer surface of the rotating shaft 8. When the rotating shaft 8 rotates, the second chuck 13 is driven to rotate, and the second chuck 13 can push the first chuck 12 to move backward. While the first chuck 12 moves backward, it pushes the sliding sleeve 10 to slide inside the sleeve 9 and compresses the spring 11. The spring 11 accumulates elastic energy after being compressed. After the first chuck 12 and the second chuck 13 are misaligned and enter the lowest point, the spring 11 pushes the sliding sleeve 10 and the first chuck 12 to contact with the second chuck 13 to limit the rotation of the rotating shaft 8. When there is no external force driving, the misaligned contact between the first chuck 12 and the second chuck 13 supported by the spring 11 limits the rotation of the rotating shaft 8, so that the vibration generated by the printing equipment cannot cause the rotating shaft 8 to rotate.

[0026] The latching teeth on the first chuck 12 all have an inclination angle, and the latching teeth on the second chuck 13 have the same inclination angle as the latching teeth on the first chuck 12. The inclination angle of the latching teeth facilitates the offset sliding between the first chuck 12 and the second chuck 13. During the sliding process, the second chuck 13 pushes the first chuck 12 to move backward.

[0027] A first mounting seat 14 is fixedly connected to one side of the slider 3, and the inner wall of the first mounting seat 14 is fixedly connected to the outer surface of the printing roller body 4. When the printing roller body 4 is operating, it needs to exert a certain pressure downward on the printed product, and at the same time, the printed product will produce the same reaction force on the printing roller body 4. The first mounting seat 14 can maintain the supporting force of the printing roller body 4 and increase the stability of the printing roller body 4.

[0028] The inner bottom wall of the lifting frame 1 is fixedly connected with a second mounting seat 15, and the inner wall of the second mounting seat 15 is rotatably connected to the outer surface of the screw 5, and the other end of the screw 5 is rotatably connected to the inner side of the support frame 2. When the screw 5 rotates, in order to prevent one end from running off-center, one end of the screw 5 is restricted by the second mounting seat 15 to maintain the concentricity of the screw 5 during rotation and increase the accuracy of the up and down sliding of the slider 3. The lower surface of the lifting frame 1 is fixedly connected with a base 16, and multiple connecting seats 17 are fixedly connected on both sides of the base 16. The lifting frame 1 and the overall equipment are supported and carried by the base 16, and the base 16 is installed and fixed by the connecting seats 17 to reduce the vibration of the printing equipment during operation and improve the stability of the overall equipment.

[0029] Working principle: When the printing equipment is operating, the spring 11 can provide elastic supporting force for supporting the first chuck 12, so that the first chuck 12 is always in misaligned contact with the second chuck 13, limiting the rotation of the rotating shaft 8. When it is necessary to adjust the distance of the printing roller body 4, the rotating shaft 8 is first rotated, and the rotating shaft 8 drives the second chuck 13 to rotate. The second chuck 13 pushes the first chuck 12 to move backward. While the first chuck 12 moves backward, it pushes the sliding sleeve 10 to slide inside the sleeve 9. At the same time, the sliding sleeve 10 compresses the spring 11. After adjusting the distance between the printing shaft body and the printed product, stop rotating the rotating shaft 8. After the first chuck 12 and the second chuck 13 are misaligned and enter the lowest point, the spring 11 pushes the sliding sleeve 10 to slide outside the sleeve 9. At the same time, the sliding sleeve 10 pushes the first chuck 12 to contact the second chuck 13, limiting the rotation of the rotating shaft 8 when there is no external force driving.
