Description

Technical Field

[0001] The utility model relates to the field of plate and strip material cleaning equipment, in particular to a plate and strip double-sided scrubber. Background Art

[0002] Metal plates, strips, etc. are flat workpieces formed by forging or rolling blanks. During the production process of metal plates and strips, foreign matter such as metal debris, impurities, dust, glue of protective film, etc. will inevitably adhere to their surfaces. In order to prevent these foreign matter from affecting the quality of the finished products, it is necessary to remove foreign matter on the surface of the plates and strips before leaving the factory or further processing to keep the metal plates and strips clean.

[0003] However, the cleaning effect of common plate and strip cleaning equipment on metal plate and strip is not ideal. This is because the common plate cleaning equipment usually cleans the plate by spraying or brushing or a combination of the two. During the cleaning process, the plate and strip will be slightly deformed due to transmission or brushing, spraying, etc., or the thickness of the plate and strip itself is uneven, resulting in the plate not being cleaned everywhere. Especially when using a brush for cleaning, the brush must be at an appropriate distance and strength from the plate and strip to ensure a good cleaning effect. If the distance is too large, the surface of the plate and strip cannot be cleaned. If the distance is too small, the brush will wear too quickly and the bristles will damage the surface of the plate and strip. However, when the existing plate and strip cleaning equipment is working, the position of the brush roller is fixed, while the surface of the plate and strip is changing, resulting in the distance between the bristles and the workpiece surface cannot be maintained within an appropriate range, which affects the cleaning effect of the plate and strip.
