Description

Wheel hub water transfer printing equipment

technical field

The invention relates to a wheel hub water transfer printing device.

Background technique

In recent years, the number of automobiles in my country has been showing an increasing trend. With the increase in the number of private cars, the automobile modification industry has developed rapidly. Among them, automobile wheels have become the parts that many private car owners are keen to modify. The common methods mainly include upgrading the size and material, spraying and printing, etc. . Among them, water transfer printing technology has become a popular technology for wheel surface printing modification due to its advantages of low cost, rich pattern personality, and not being affected by the uneven shape of the printing surface.

Water transfer printing technology includes two types of water mark transfer technology and water coating transfer technology. Most of the modifications to the hub are water coating transfer technology. The water coating transfer technology uses a water-based film that is easily dissolved in water to carry pictures and texts. The film that has undergone special chemical treatment is printed with the desired color pattern and then sent to the surface of the water. After the film is dissolved but does not destroy the activator of the texture on the film, the color texture pattern is evenly transferred to the surface of the product by the action of water pressure. After cleaning and drying, a transparent protective coating is applied. It can make the product present a completely different visual effect and solve the problem of printing on three-dimensional products.

During the transfer process of the hub, after the hub to be transferred is put into the water, the transfer film remaining around the hub floats on the water surface, and the transfer film remaining in the water is easily covered on the surface of the hub again when the hub is picked up in the water. To affect the transfer pattern, now the wheel hub is swayed in water to keep the remaining transfer film away from the wheel hub and then take out the wheel hub, which affects the transfer efficiency and the worker's physical strength. In addition, due to the large volume of the hub, the water surface will fluctuate when it is taken out, which is not conducive to placing a new transfer film. As a result, it is necessary to wait for the water surface to stabilize before transferring the next hub. At the same time, the water transfer technology has requirements for the water entry angle of the hub to be transferred, so it is necessary to design a water transfer device that can clean the residual transfer film on the water surface, adjust the water entry angle of the hub, and quickly smooth the water surface fluctuations.
