What are the effects of using a small coating machine spray gun for too long:


Spray gun blockage: Spray gun blockage is a common problem, and the formation of blockage is mainly due to problems in the design of the spray gun air path. Some imported spray guns also have such design defects.


Spray gun pulse: Spray gun pulse is mainly caused by peristaltic pump, and pulse is an important factor affecting coating quality. There are many ways to eliminate pulse, such as increasing the length of the pipeline after peristaltic pump is discharged, adding adjustment structures, and so on.


Spray gun dripping: Spray gun dripping mostly occurs during gun cleaning. It is often said by manufacturers that clogging the spray gun can be done by cleaning the gun, but this is incorrect! The blockage of the spray gun can be divided into whisker blockage and membrane blockage. The second cleaning gun is a treatment method that occurs when the membrane is blocked.


Spray gun adjustment: The old-fashioned spray gun adjustment mechanism is basically manually adjusted, and all distances, such as the distance from the gun to the drug surface, and the spray gun adjustment mechanism are basically manually adjusted. All distances, such as the distance from the gun to the drug surface, and the angle of the spray gun, are artificially simulated and adjusted without a quantitative indicator.


Daily maintenance and upkeep methods for small coating machines:


1. The lubricating oil inside the gearbox and the lubricating grease inside the rolling bearing should be replaced regularly.


2. If the sugar coated pot is not used for a long time, it should be wiped clean and coated with oil on its surface to prevent the oxidation of the pot material or the generation of toxic copper compounds after being damp.


3. To ensure the lubrication conditions of the worm gear transmission in the gearbox, the temperature rise of the gearbox during operation shall not exceed 50C.


4. The oil proof sealing ring at the end of the worm shaft should be regularly inspected and replaced.


5. The machine must be reliably grounded, and its grounding resistance should be ≤ 4 Ω. 6. Do not remove electrical appliances and belt protective covers without authorization.


6. Clean the surface and interior dust, and keep the machine clean and hygienic. Although dust is small, it can damage the machine and make the coating machine run slowly, even unable to operate. So, it is important to regularly clean the dust from the coating machine.
