Description

Technical Field

[0001] The utility model relates to the technical field of plastic spraying lines, in particular to a plastic spraying line capable of performing plastic spraying and paint spraying at the same time. Background Art

[0002] Plastic spraying is a surface treatment method in which plastic powder is sprayed onto parts. The advantages are that no thinner is required, the construction is environmentally friendly, non-toxic to the human body, the coating has excellent appearance quality, and strong adhesion and mechanical strength.

[0003] Currently available plastic spraying lines generally have the disadvantage of low working efficiency. Usually plastic spraying lines only have the function of plastic spraying. Plastic spraying and paint spraying are separate processes. The entire production process of the product is relatively slow, which continuously consumes manpower and easily causes damage to the machinery. Its working efficiency is also relatively slow and it is inconvenient to use.

[0004] After searching the existing Chinese patents: a plastic spraying line that can perform plastic spraying and painting at the same time (publication number: CN212092910U), including two side panels, the left and right sides of the bottom of the side panels are fixedly installed with fixed plates. The plastic spraying line that can perform plastic spraying and painting at the same time can push the processing part to the right by starting the driving motor and rotating the rotating wheel. When the part is pushed to the bottom of the plastic spraying gun, the pushing cylinder on the plastic spraying gun is started to push the piston down. By setting a connecting rod, the piston can move more stably, and the internal pressure of the receiving box at the top of the plastic spraying gun is increased, and the plastic spraying gun can be used to spray the processed part. After the plastic spraying is completed, the workpiece continues to be pushed to the right. When it reaches the bottom of the paint spraying gun, the pushing cylinder at the top of the paint spraying gun is started. Similarly, the paint contained in the right receiving box can be sprayed on the workpiece, thereby completing the painting and plastic spraying processes at the same time, so that the equipment achieves the purpose of high work efficiency.

[0005] Although the above-mentioned Chinese patent has achieved the goal of completing the painting and plastic spraying processes at the same time, making the equipment achieve the purpose of high working efficiency; however, the device lacks a drying mechanism, and it takes a lot of time to dry the paint after the spraying is completed, which is not conducive to subsequent transportation and processing, affecting the overall processing efficiency of the workpiece. Incompletely dried workpieces are prone to paint loss during transportation, affecting the spraying effect of the finished product.

[0006] Therefore, it is necessary to invent a plastic spraying line that can simultaneously perform plastic spraying and paint spraying to solve the above problems. Utility Model Content
