Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating machines, and more particularly to a coating device with pressure regulation. Background Technology
[0002] A coating device is a piece of equipment used to uniformly apply a liquid coating onto the surface of a substrate. It is widely used in industries such as paper, film, paint, and electronic materials. The basic principle of a coating device is to uniformly coat the material surface with a coating through a certain coating method. Its core components include coating rollers, doctor blades, paint tanks, and drying systems. The coating rollers transfer the coating onto the substrate through contact with the substrate, while the doctor blades control the thickness of the coating to ensure uniform coating.
[0003] The design of coating equipment must consider the uniformity of the coating, the drying rate, the compatibility of materials, and the operational stability of the equipment. Modern coating equipment is equipped with an automated control system that can monitor the quality and thickness of the coating in real time, ensuring precise control of the production process. Drying during the coating process is crucial. Solvents or moisture in the coating are usually removed by ovens or infrared heating systems to form a strong coating.
[0004] Current coating equipment already includes pressure regulating devices, which can manually or electrically control the pressure of the rollers and the doctor blade to change the coating thickness. However, in traditional coating equipment, multiple rollers are linked by gears or chains, and after long-term operation, the gears and chains need to be lubricated. The traditional lubrication method is manual application, which is time-consuming, labor-intensive, and inefficient. Therefore, a coating device with pressure regulation is proposed to solve the above problems. Utility Model Content

[0036] Working Principle: When using the coating machine 1 for coating, first adjust the pressure of the roller and the doctor blade according to the requirements. Then, add the coating material into the coating machine 1. At this time, control the coating machine 1 to work. The roller drives the substrate to be conveyed and contact the coating material. With the help of the doctor blade, the coating material is evenly spread. At the same time, control the fan 14 to work, so that the air collection port 13 generates suction to suck away the debris and the odor emitted by the coating material. The gas enters the housing 11 along the air pipe 12 and is purified by the activated carbon filter 16. The gas is filtered and harmful substances are adsorbed before being discharged into the air to avoid gas pollution of the working environment. After a period of use, a certain amount of impurities are collected in the collection frame 15 and the adsorption effect of the activated carbon filter 16 decreases. At this time, it is necessary to replace the activated carbon filter 16 and remove the impurities. By pulling the insertion rod 18, the sliding plate 20 compresses the spring 21, disengaging the insertion rod 18 from the collection frame 15. At the same time, the stop rod 22 automatically falls and inserts into the insertion hole 19 to prevent insertion. When rod 18 automatically resets, collection frame 15 is unlocked. Remove collection frame 15 from housing 11, clean away impurities, and replace activated carbon filter 16 with a new one. Then reinsert collection frame 15 into housing 11. Pull up stop rod 22 to disengage from insertion hole 19. Spring 21 will immediately push slide plate 20, causing insertion rod 18 to reset and be inserted into collection frame 15, thus fixing collection frame 15. It can then be used again. After a period of use, the gears and chains inside coating machine 1 need to be lubricated in time. By opening valve 8, spring 3 will immediately push piston 4 to reset, creating positive pressure in housing 2. This, along with the roller shaft of coating machine 1, drives cam 10 to rotate, pushing slide rod 5 to squeeze piston 4, compressing spring 3, creating negative pressure in housing 2. This, along with the one-way valves 7 on both sides, delivers lubricating oil from oil tank 9 along oil pipe 6 to coating machine 1, thus lubricating gears and chains. The operation is convenient and labor-saving.
