Dip-coating and drying integrated machine for Dacromet treatment

Abstract

The invention discloses a dip-coating and drying integrated machine for Dacromet treatment and relates to the technical field of Dacromet treatment equipment. The dip-coating and drying integrated machine for Dacromet treatment comprises a dip-coating mechanism, a drying mechanism and a conveyor which are successively arranged from front to back. The dip-coating and drying integrated machine for Dacromet treatment also comprises movable carrying transportation mechanisms which can be fixed above the dip-coating mechanism, the drying mechanism or the conveyor, separately. The dip-coating and drying integrated machine for Dacromet treatment disclosed by the invention can be used for coating, draining and drying workpieces, is high in integrated degree, reduces severe collision in a workpiecetransfer process and improves the coating effect of the workpieces; in the coating process, contact of a dip-coating liquid and the workpieces is increased and accumulation of the workpieces is avoided; in the drying process, a hot air flow and the workpieces are in contact favorably and accumulation of the workpieces is avoided, so that the surfaces of the workpieces can be heated uniformly, thedrying effect can be optimized and the drying time can be shortened.

Description

technical field [0001] The invention relates to the technical field of dacromet treatment equipment, in particular to a dip-coating and drying integrated machine for dacromet treatment. Background technique [0002] Dacromet is a new type of anti-corrosion coating. During the whole process of production, processing and workpiece coating, Dacromet will not produce waste water, waste gas and waste residue that pollute the environment. It is a green and environmentally friendly metal surface treatment technology. . Dacromet has high corrosion resistance, high heat resistance, no hydrogen embrittlement, strong permeability, good environmental protection, and the formed coating has good bonding force with the metal substrate. Dacromet coated on the surface of the metal workpiece Luo coating can play a good role in protecting metal workpieces, and has been widely used in auto parts, subway tunnels, railways, highways, bridges, electrical appliances, hardware tools and other field...

AI Technical Summary

Problems solved by technology

[0006] (1) During the dip coating process, although there is relative movement between the workpiece and the dacromet dipping solution, the workpieces are relatively static, and the workpieces that are piled up on each other are prone to the problem of uneven coating;

[0007] (2) Dacromet coating itself has a certain viscosity, which is easy to make small-sized and small-sized workpieces stick to each other after coating, and form "agglomerates" after curing and sintering, and the centrifugal force generated during the draining process may intensify This "caking" phenomenon;

[0008] (3) Different processes in the production process need to use different equipment. In the process of transferring from the dipping machine to the drying furnace, there will be more severe collisions during the dumping and transportation of the workpiece, which will easily cause localized coating on the surface of the workpiece. Peeling, thus affecting the coating effect

[0009] The above-mentioned factors not only affect the appearance of the workpiece, but also lead to the failure of the physical performance of the workpiece in severe cases, or cause the anti-corrosion effect of the surface coating of the workpiece to fail to meet the requirements, reducing the yield
