Description

Technical Field

[0001] The utility model belongs to the technical field of coating equipment, and particularly relates to a surface coating equipment for MPP pipes made of plastic materials. Background Art

[0002] Most plastic blank products are formed by extrusion or compression molding. During the heat extrusion process, trace amounts of air or volatile impurities in the raw materials may escape to the surface, forming many microscopic defects such as "crater", resulting in a decrease in surface gloss and poor aesthetics. In addition, most conventional plastic parts have low wear resistance and solvent resistance, and are prone to scratching, fogging, surface damage, etc. Therefore, it is necessary to perform surface decoration and protection on plastic parts. Plastic materials with poor light aging performance can also be coated and protected with light-stabilized UV coatings to prevent or delay the aging of plastic substrates, which is particularly important for occasions that are often used outdoors and are exposed to sunlight and artificial short-wave light sources (such as fluorescent lamps) for a long time.

[0003] In the related art, an automatic coating device for the surface of plastic products is disclosed, including legs and a sliding device. A first base is distributed above the legs, and a motor box is arranged on the left side of the first base. A maintenance door is installed on the front side of the motor box. A second base is distributed above the motor box, and a rotating base is installed above the second base. The sliding device is fixed above the rotating base, and a plastic product body is connected to the right side of the sliding device. The automatic coating device for the surface of plastic products is provided with a rotating shaft. The rotating shaft, a micro motor and a gear form a rotating structure. After the user starts the micro motor, the micro motor drives the gear to rotate synchronously through the rotating shaft. The right side of the slide rail is a toothed structure, and the gear is meshed with the slide rail. Therefore, when the gear rotates, the gear drives the slider to perform a linear reciprocating motion along the slide rail, and its coating operation is automatically completed by the device, which can improve the coating efficiency of the plastic product surface and greatly save the labor of the user.
