AI Technical Summary

Technical Problem

During the speaker housing painting process, the paint tends to pool at the bottom, resulting in a thicker paint layer on the lower side, which affects the painting effect. Furthermore, after painting, it is necessary to wait for it to dry or transfer it to a drying device, which affects the production schedule.

Method used

A coloring and painting device for speaker housing processing was designed, comprising a transfer mechanism, a spraying section, and a drying section. Driven by a motor and an electric cylinder, spraying and drying are performed simultaneously. A limiting part and a rotating plate structure are used to prevent paint from pooling. A frustum structure and a fixed ring support are used to ensure uniform spraying.

Benefits of technology

It improves spraying efficiency, prevents paint from pooling at the bottom of the casing, ensures spraying quality, and saves time on painting and drying, thus improving processing efficiency.

Abstract

The utility model belongs to loudspeaker shell processing technical field especially, be a kind of colouring paint spraying device for loudspeaker shell processing, present and propose the following scheme, including work bench, remove and send mechanism and electric cylinder by support installation on work bench on installation on work bench, electric cylinder can be used to drive spraying part and drying part, remove and send mechanism includes motor one, connecting plate, mobile seat, rotary plate, limiting portion, motor two, conducting plate and conducting ring. The device of the utility model is convenient in the process of respectively spraying paint and drying to loudspeaker shell on two groups of rotary plates, the loudspeaker shell on third group of rotary plates is disassembled and placed, effectively save time in the whole process, improve the processing efficiency of loudspeaker shell, and avoid after loudspeaker shell is finished spraying, paint liquid is collected in the bottom of loudspeaker shell, leading to that paint liquid on loudspeaker shell is not enough uniform, influence paint spraying quality.
