The transfer machine has a wide range of uses. Among them, all the roll coaters for external wall insulation boards can be divided into two types. One is a UV transfer machine suitable for UV paint coating operations. The other is a roller coater suitable for fluorocarbon paint coating operations. The method of extending the life of the roll coater is as follows:
First, the roller coating machine used for fluorocarbon paint, you have to consider the problem of cleaning every shift, because the fluorocarbon paint for external wall insulation boards currently on the market is basically a self-drying baking paint. Generally, The film can be formed dry in 30 minutes at normal temperature. Based on the limitation of this condition, when maintaining the fluorocarbon paint roller coater, when the production interval exceeds 30 minutes, and there is no new supply of circulating paint, Immediately clean the paint on the coating roller and paint roller. Otherwise, when the paint is cured on the surface of the coating rubber roller, it will cause a very large quality hazard to the subsequent coating operation until the rubber roller is damaged.
Second, the UV transfer machine can be based on the UV paint is cured by ultraviolet paint, that is to say, this type of paint will not be cured without encountering ultraviolet light. In this way, when the UV transfer machine is maintained, it can be purposefully maintained to increase its service life: for example, when the production interval is less than three days, the coating rubber roller can be cleaned, only the uniform Separate the paint roller from the coating roller and ensure that the surface is not heavily painted. This not only saves the cost of cleaning, but also reduces the probability of damage to the coating roller!
Third, the main configuration and application of UV transfer machine:
1. The rubber roller adopts imported material PU rubber roller with a diameter of 250MM. The roller surface diameter is precisely processed by computer.
2. The smooth roller adopts a large smooth roller with a diameter of 130MM, the roller surface is chrome-plated, and the outer circle is precisely processed by a CNC grinding machine.
3, equipped with imported materials strong toughness scraper, adjusted by a small worm gear reducer, high accuracy.
4. The conveyor belt is a 3MMPU anti-slip belt, which is resistant to various solvents, prevents chemical corrosion and causes layer formation, and adds anti-skew devices.
5. The operation of the smooth roller and rubber roller is controlled by an independent frequency converter and reducer. The distance between them is adjusted by the eccentric shaft of the worm machine and the dovetail mechanism is driven. The error value is 0.05MM.
6. The UV transfer machine is equipped with a workpiece thickness measuring device, which can adjust the roller pressure according to the different thickness of the product. When the workpiece thickness is greater than the set value, the machine will automatically stop.
7, bearing seal structure to prevent paint penetration.
8. The whole machine is equipped with five Taiwan Delta inverters and five reducers.
9. The lifting system adopts a dovetail groove type lifting seat, which has no shaking during lifting, and has good stability. A far-infrared detection device is installed at the material inlet to prevent the entry of unsuitable materials.
10. The whole machine is equipped with a diaphragm pump and a 40L heating oil tank.
