Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a spraying device with uniform spraying thickness. Background Technology

[0002] Barrels are commonly used for storing, transporting, or packaging goods. During the production of barrels, the outer wall of the barrel needs to be painted to provide anti-corrosion protection and prevent the barrel material from coming into contact with the external environment. Moisture, chemicals, or other corrosive factors in the external environment may damage the appearance of the barrel, causing the surface of the barrel to corrode, oxidize, or rust. The paint layer can prevent these corrosive factors from eroding the barrel wall, thereby extending the service life of the barrel.

[0003] Existing technologies have the following problems:

[0004] After extensive searching, it was found that the patent document with application number CN202421062042.3 discloses a spraying device with uniform coating thickness. The patent uses a first electric push rod and an arc plate to fix and clamp the upper end of the barrel-shaped object. Then, the electric slide rail drives the spray gun on the front side of the moving block to move up and down to spray the barrel-shaped object.

[0005] However, the aforementioned patent still has some problems in actual use. The most obvious problem is that when the stencil filters the dripping spray liquid, some impurities are inevitably present in the spray liquid. These impurities accumulate over time and can cause the stencil to become clogged. When maintaining the stencil, workers need to disassemble it, which requires stopping the machine and wasting a lot of time, thus affecting the spraying efficiency.

[0006] To address these shortcomings, we have proposed a spraying device that provides uniform coating thickness. Utility Model Content
