AI Technical Summary

Technical Problem

Existing metal surface spraying equipment often creates dead zones for mixing inside the paint tank, making it difficult for the paint to mix fully at the bottom. In particular, the mixing effect in the vertical direction is poor, affecting the uniformity and stability of the paint.

Method used

It adopts a combination structure of active bevel gear, driven bevel gear, movable shaft, turntable, pull plate, connecting seat, lifting rod and lifting plate. The stirring shaft is driven to rotate by servo motor, which drives the bevel gear and stirring blade to rotate. At the same time, the lifting plate moves up and down in the paint tank to achieve multi-dimensional stirring. Combined with the vertical stirring force of the lifting plate, it ensures that the paint is fully mixed.

Benefits of technology

It effectively reduces dead zones in the mixing process, improves the uniformity and mixing effect of the coating, ensures uniform pigment dispersion, and fully integrates the solvent and solute, thereby enhancing the mixing effect of the coating.

Abstract

This utility model discloses a metal surface spraying device, relating to the field of metal surface processing. The device includes a spraying box with a paint tank mounted on its back. A top plate is bolted to the top of the paint tank, and a housing is fixed to the top of the top plate. The device comprises a driving bevel gear, a driven bevel gear, a turntable, a pull plate, a lifting rod, and a lifting plate. When the paint needs to be stirred, a second servo motor drives the stirring shaft to rotate. The stirring shaft then drives the driving bevel gear and the stirring blade to rotate. The driving bevel gear drives the driven bevel gear to rotate, which in turn drives the movable shaft to rotate. The movable shaft then drives the turntable to rotate. The rotation of the turntable pulls the pull plate, which in turn pulls the connecting seat upwards, causing the lifting rod to move upwards and the lifting plate to move upwards. As the second turntable continues to rotate, the lifting plate can move up and down repeatedly. The lifting plate can directly act on the paint at the bottom of the paint tank, effectively reducing the bottom stirring dead zone.
