A pressure plate structure of filter cotton in dynamic pressure chamber for automobile painting and spraying

Abstract

The invention discloses a pressure plate structure for a filter cotton in a dynamic pressure chamber for automobile painting and spraying, which includes a bottom plate of the dynamic pressure chamber and a windshield. The positioning structure for positioning the windshield, one side of the pressure plate frame is hingedly connected with the bottom plate of the dynamic pressure chamber, and the other side of the pressure plate frame is provided with a locking structure for locking on the bottom plate of the dynamic pressure chamber, the positioning The structure is set on the platen frame. The structural design of the filter cotton pressure plate in the dynamic pressure chamber of the automobile painting painting is reasonable. The windshield only needs to be adjusted and fixed for the first time according to the requirements of the wind pressure, wind direction, and laminar flow of the entire paint spraying room. There is no need for repeated adjustments in the subsequent process, which reduces filtration. The time for cotton replacement and wind pressure and wind direction adjustment avoids batch quality accidents caused by unstable wind direction in the spray booth; low manufacturing cost, stable performance, convenient control, low post-maintenance cost, does not affect the existing production line layout, and the overall appearance.

Description

technical field [0001] The invention relates to the technical field of automobile painting, in particular to a filter cotton pressing plate structure of a dynamic pressure chamber for automobile painting and spraying. Background technique [0002] In the design of the dynamic pressure chamber of the spray booth of the automobile coating production line, the filter system of the dynamic pressure chamber adopts 3-4 rows of bag filters with a filtration accuracy grade of F6 (medium efficiency), and the number of each row depends on the space and wind speed requirements of the spray booth It depends, generally more than 30 pieces. [0003] In order to meet the requirements of air cleanliness and equal pressure wind speed in the spray booth, the medium-efficiency filter system of the dynamic pressure room needs to be replaced regularly during the production process. At present, in the process of replacing the filter, a lot of manpower and time are required to disassemble it; aft...

AI Technical Summary

Problems solved by technology

At present, in the process of replacing the filter, a lot of manpower and time are required to disassemble it; after the replacement, it is necessary to continuously adjust the opening size of each medium-efficiency filter baffle to meet the uniform wind pressure and laminar flow of the entire spray booth. It takes a lot of time and energy to adjust, and it is not easy to adjust in place, resulting in batch quality accidents, etc.
