Corrosion-prevention coating equipment for metal wire mesh grid

Abstract

The invention discloses corrosion-prevention coating equipment for a metal wire mesh grid, which successively comprises a curling machine, a pretreatment system, electrostatic coating equipment, a powder dispersing system, a powder drying and solidifying drying channel and a rolling machine, wherein the stations of the electrostatic coating equipment, the powder dispersing system and the powder drying and solidifying drying channel are respectively provided with a clamp-type stretching conveyor; the clamp-type stretching conveyor comprises a conveying chain a and a conveying chain b, wherein the conveying chain a is positioned on the stations of the electrostatic coating equipment and the powder dispersing system; the conveying chain b is positioned on the station of the powder drying and solidifying drying channel; and a needle plate type chain belt system used for temporarily fixing the metal wire mesh grid is arranged at the adjacent position of the conveying chain a and the conveying chain b. Due to a horizontal structure, 2-8 overlapping type production lines can be installed according to the requirement of a production program, the occupied land is small, and the heat efficiency use ratio is high. The metal wire mesh grid with a high quality requirement can be used for replacing stainless steel wire weaving, the manufacture cost is lowered, and the processing equipment is arranged in the sealed environment and has small pollution on the environment.

Description

technical field [0001] The invention belongs to the technical field of industrial coating equipment, and in particular relates to a fully automatic equipment for performing anti-corrosion coating treatment on metal wire braided mesh workpieces. Background technique [0002] At present, the coating method of metal wire mesh adopts a simple coating equipment that directly sprays powder on the vertical bare net and then solidifies it. There is a net release rack in front of the equipment and a net collection rack in the back. The wire mesh is used as the transmission belt for transmission operation. Because the bare mesh has dust and oil in the weaving production process, if it is not cleaned and sprayed directly, the powder adhesion is poor and it is easy to fall off, which seriously affects the service life of the mesh. Another fatal defect is to rely on the wire mesh as a transmission belt to operate. During the operation, due to the influence of the warp and weft t...

Problems solved by technology

Because the bare mesh has dust and oil in the weaving production process, if it is not cleaned and sprayed directly, the powder adhesion is poor and it is easy to fall off, which seriously affects the service life of the mesh

Another fatal defect is to rely on the wire mesh as a transmission belt to operate. During the operation, due to the influence of the warp and weft tension of the wire mesh and the uneven transmission force during the wire mesh transmission process, the mesh structure of the wire mesh will be deformed. Seriously affect the technical quality of the screen

Due to the influence of the warp and weft tension of the wire mesh, the speed of production and operation of the wire mesh will appear during the coating process, the structure of the wire mesh will be tight and loose, and the thickness of the powder coating will be uneven. It will block the mesh square hole structure

Due to the backward development of anti-corrosion coating equipment for wire mesh, there is no special wire mesh coating production line equipment in China, so some domestic wire mesh manufacturers directly supply bare wire mesh with lower technical requirements without any coating protection deal with
