Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment. Background Art

[0002] Rubber blankets play a vital role in the printing industry, not only protecting the quality of printed products but also improving printing efficiency. Soft and wear-resistant, rubber blankets effectively protect printed surfaces from scratches and damage. During the printing process, as part of the printing press, the rubber blanket creates a certain amount of pressure between the printing plate and the printed product, ensuring even contact between the printed product and the ink on the plate while preventing damage from direct contact between the plate and the printed product. The rubber blanket's softness and elasticity allow it to adapt to printed products of varying shapes and sizes, facilitating a smoother printing process. It evenly distributes pressure, ensuring even ink transfer to the printed product, thereby improving printing quality and efficiency.

[0003] Rubber blankets must be kept clean during use to prevent impurities from building up and hardening into a solid mass, thereby affecting their performance. Cleaning the blanket is crucial to ensuring its long-term use and performance. Proper cleaning methods and the use of appropriate cleaning fluids can effectively remove dirt and extend the life of the blanket. However, conventional techniques often overuse blankets, accumulating impurities such as dust, paper lint, powder, and fillers. Manually removing these impurities is time-consuming and labor-intensive, and can easily lead to inadequate cleaning, shortening the blanket's lifespan and impacting its performance. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic cleaning device for a rubber cloth in order to solve the above technical problems.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A rubber cloth automatic cleaning device includes a cleaning tank, a receiving roller for carrying the rubber cloth is provided on the cleaning tank, a guiding mechanism is provided on one side of the receiving roller, the cleaning tank carries washing liquid, and a double-sided cleaning mechanism is provided in the cleaning tank below the guiding mechanism, the double-sided cleaning mechanism includes slag removal rollers symmetrically arranged in the cleaning tank and driven by a motor, the slag removal rollers are distributed in several groups, and bristles are distributed on the periphery of the slag removal rollers, the double-sided cleaning mechanism also includes a residue stripping unit provided in the cleaning tank, and a sponge cleaning roller is provided at the output end of the cleaning tank.

[0007] Through the above scheme, the rubber cloth to be cleaned is wound on the receiving roller and guided into the cleaning tank by the guiding mechanism. The rubber cloth is cleaned with the washing liquid and repeatedly cleaned by the residue removal roller and the bristles, and the residue on the periphery of the rubber cloth is cleaned by the residue stripping unit, and the residue debris and printing oil on the periphery of the rubber cloth are cleaned. Then the rubber cloth enters the sponge cleaning roller to clean the water stains on the periphery. The whole process has a high degree of automation, cleanness, high operating efficiency, and can be adapted to batch cleaning of rubber cloths, which greatly improves the cleaning efficiency and saves labor.

[0008] Furthermore, the guiding mechanism includes guiding rollers symmetrically distributed on the side walls of both sides of the cleaning tank. The guiding rollers are driven by a motor, and the outer periphery of the guiding rollers is covered with a rubber layer.

The sponge cleaning roller 14 is driven by a chain drive from two motors in the same group, which drives the sponge cleaning rollers 14 in relative motion, facilitating the pulling of the blanket. The rubber cloth to be cleaned is wound on the receiving roller 12 and guided into the cleaning tank 11 by a guiding mechanism. The rubber cloth is cleaned with washing liquid and repeatedly cleaned by the residue removal roller 13 and the bristles, and the residue on the periphery of the rubber cloth is cleaned by the residue stripping unit. The residue debris and printing oil on the periphery of the rubber cloth are cleaned, and then the rubber cloth enters the sponge cleaning roller 14 to clean the water stains on the periphery. The whole process has a high degree of automation, cleanness, high operating efficiency, and can adapt to batch cleaning of rubber cloths, which greatly improves the cleaning efficiency and saves labor.

[0032] Reference Figure 1 and Figure 3The rubber blanket is soft, easily stacked, and inconvenient to clean. To facilitate the pulling of the blanket, a guide mechanism is provided. The guide mechanism includes guide rollers 15 symmetrically distributed on the side walls of the cleaning tank 11. The guide rollers 15 are driven by a motor and coated with a rubber layer. The motor-driven guide rollers 15 facilitate the movement and guidance of the blanket. The rubber layer also provides an anti-slip function, preventing the blanket from slipping.

[0033] Reference Figure 1 and Figure 2 and Figure 3 At least two groups of guide rods 15 are provided on the side wall of the same side of the cleaning tank 11. The guide rods 15 are symmetrically distributed in a group of two on the side wall of the same side of the cleaning tank 11. Belt transmission is adopted between the guide rods 15 in the same group. The cleaning tank 11 is provided with an anti-pinch mechanism at the guide rods 15. The anti-pinch mechanism includes a travel groove 16 provided on the side wall of the cleaning tank 11 above the guide rod 15. A slider 17 and a tensioning spring 18 are provided in the travel groove 16. The tensioning spring 18 has a tendency to urge the slider 17 to move away from the travel groove 16. Among the two guide rods 15 symmetrically distributed on the same side of the cleaning tank 11, one guide rod 15 is connected to the motor, and the other guide rod 15 is connected to the slider 17.
