Description

Technical Field

[0001] The invention relates to the technical field of spraying, in particular to a pipeline polytetrafluoroethylene paint spraying device capable of recycling the paint. Background Art

[0002] PTFE coating is a material with special properties. PTFE coating has excellent properties such as non-stickiness and high temperature resistance, which makes it widely used in many industries and fields.

[0003] In the prior art, the spraying of PTFE coatings on pipes often has some shortcomings. For example, it is difficult to achieve stable straight-line transportation when conveying the pipe to be sprayed, which may lead to uneven spraying effect. Moreover, during the spraying process, the traditional spraying device often cannot ensure that the PTFE coating is evenly attached to the pipe surface, affecting the product quality.

[0004] In addition, when the pipeline is sprayed, a large amount of excess paint will adhere to the inner wall of the spray cover. If these paints are not treated, it will not only cause a waste of resources, but also increase costs. More importantly, the excess untreated paint may pollute the environment and does not meet environmental protection requirements.

[0005] In order to solve these problems, the present invention came into being. Through a unique design, the first conveying trough and the second conveying trough are set to realize the linear conveying of the pipeline to be sprayed, ensuring the stability and uniformity of the spraying. At the same time, the setting of the spraying assembly enables the polytetrafluoroethylene coating to be sprayed evenly during the pipeline transportation process. More importantly, the synergistic effect of the scraping and recycling mechanism and the integrated driving mechanism effectively scrapes and recycles the excess coating adhered to the inner wall of the spraying cover, realizing the reuse of resources, reducing costs and protecting the environment.

[0044] During the implementation of the present invention, firstly, the pipe 4 to be sprayed is placed in the first conveying trough 2, and the pipe is pushed to move in the first conveying trough 2 by equipment or manually.
