Description

Technical Field

[0001] The invention relates to the technical field of chemical tin solution production, in particular to a raw material conveying device for chemical tin solution production. Background Art

[0002] Chemical tin solution is an important chemical substance used for metal surface treatment. It reduces tin metal ions and deposits them on the surface of the substrate to form a uniform and dense tin layer to improve the corrosion resistance and aesthetics of the metal surface. In the electronics industry, chemical tin solution is used to enhance the solderability and oxidation resistance of electronic components, while in decorative plating, it provides a lead-free, environmentally friendly alternative.

[0003] The raw materials for the production of chemical tin solution mainly include tin raw materials and chemical raw materials. When conveying the raw materials for its production, a conveying device is usually used. According to the patent application number CN202320206140.9, in this aluminum raw material conveying device, the conveyor belt cleaning mechanism can clean the aluminum raw materials attached to the surface of the conveyor belt, improve the smoothness of the conveyor belt surface, and prevent the aluminum raw materials attached to the surface of the conveyor belt from accumulating, thereby causing waste of aluminum raw material transportation; in this aluminum raw material conveying device, the conveyor belt beating mechanism can beat the conveyor belt, and the aluminum raw materials attached to the surface of the conveyor belt are vibrated, causing the aluminum raw materials to fall, thereby strengthening the cleaning of the conveyor belt surface;

[0004] When the conveying device in the above patent is used to transport the raw materials for the production of chemical tin solution, the quantitative feeding of the raw materials cannot be achieved, which affects the ratio accuracy of the raw materials in the production process of the chemical tin solution.
