Description

Technical Field

[0001] The present invention relates to the technical field of industrial dust removal equipment, in particular to a negative pressure dust removal and cleaning mechanism with a spraying function and a dust removal and cleaning method, which are suitable for mold cleaning operations in brake pad production. Background Art

[0002] During the brake pad production process, after the brake pads are pressed and demolded, the mold must be cleaned of reaction residue. The next production run also requires spraying a release agent and cleaning the friction powder that landed on the mold surface during material addition. Conventional processes lack dust covers or vacuum mechanisms, causing friction powder and reaction residue to be blown into the air and surrounding areas during cleaning, polluting the environment and endangering health, failing to meet environmental protection requirements. Existing equipment lacks an integrated design, separating dust removal and spraying processes, resulting in low efficiency.

[0003] Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0015] According to a further optimization solution, a ventilation hole is provided on the upper portion of the cleaning brush, and the ventilation hole is connected to the dust suction pipe through a conduit.
