Pressing plate structure of filter cotton of painting dynamic pressure chamber for automobile coating

Abstract

The invention discloses a pressing plate structure of filter cotton of a painting dynamic pressure chamber for automobile coating. The pressing plate structure comprises a dynamic pressure chamber bottom plate and a wind shield, a filter cotton mounting port is formed in the dynamic pressure chamber bottom plate, the pressing plate structure further comprises a pressing plate frame and a positioning structure used for positioning the wind shield, one side of the pressing plate frame is hinged to the dynamic pressure chamber bottom plate, a locking structure used for being locked on the dynamicpressure chamber bottom plate is arranged at the other side of the pressing plate frame, and the positioning structure is arranged on the pressing plate frame. The pressing plate structure of the filter cotton of the painting dynamic pressure chamber for automobile coating is reasonable in structural design; the wind shield only needs to be adjusted in position and fixed according to the requirements of air pressure, air direction, laminar flow and the like of the whole painting chamber for the first time, repeated adjustment is not needed in the follow-up process, the time for filter cottonreplacement, and air pressure and air direction adjustment is shortened, and batch quality accidents caused by the unstable wind direction of the painting chamber are avoided; and the manufacturing cost is low, the performance is stable, the control is convenient, the later maintenance cost is low, the existing production line arrangement is not influenced, and the whole appearance is attractive.

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.
