This invention relates to the field of silicone product spraying technology, specifically disclosing a spraying device for surface treatment of silicone products. The device includes a worktable with notches at both ends, a conveyor belt at the notches, and a protective cover on top. The invention utilizes connecting parts and clamping blocks. The clamping blocks secure the silicone product on the worktable, while the two connecting parts move to opposite sides of the product. Activating the spray nozzle completes the spraying of the silicone product. During spraying, a rotary motor drives a rotating rod to reciprocate, allowing the silicone product to be sprayed without rotating itself. This method prevents the silicone product from shifting before the coating cures due to inertia from its own rotation, thus improving the spraying quality.

This invention relates to the field of solid waste treatment technology, specifically a process for processing and utilizing silicone products. The process includes first cleaning and removing contaminants from the silicone products in a cleaning box, then drying them before they fall into a crushing box. The silicone products are separated and piled up by a distribution plate. The rotation of the linkage column in the main crushing unit simultaneously drives the upper distribution blade and the lower crushing blade. Simultaneously, the rotation of the linkage column in the auxiliary crushing unit simultaneously drives the upper distribution blade and the lower double blade, all working together to compress and cut the silicone products. Long or large silicone products are first cut or shredded by the distribution blade and fall to the bottom of the crushing box, where they are further crushed into smaller pieces by the crushing blade and the double blade. This reduces the working pressure on the servo motor. A baffle plate and a spring plate disperse the broken silicone product pieces, ensuring the crushing box remains clean after unloading, eliminating the need for time-consuming manual cleaning.
