Abstract

The invention discloses a vacuum extraction powder pump control system. The vacuum extraction powder pump control system comprises two or more powder conveying devices which are arranged in parallel.Each powder conveying device is provided with a powder cavity. Each powder cavity is provided with a feeding opening and a discharging opening. Each feeding opening is provided with a first opening and closing valve, and each discharging opening is provided with a second opening and closing valve, so that each feeding opening and each discharging opening are controlled to be opened and closed. Each powder cavity is connected with an air supply pipe and an air extraction pipe. Connection positions of air inlet pipes and the air extraction pipes are arranged to be close to the feeding openings and the discharging openings. The vacuum extraction powder pump control system is provided with the multiple powder conveying devices; in the working process, the multiple powder conveying devices canbe arranged to convey powder sequentially; powder conveying efficiency is improved; compressed air mingled in the powder conveying process is reduced; the powder conveying density is increased; production efficiency is improved; and the vacuum extraction powder pump control system has the cleaning function and is convenient to use and high in practicability.

Description

technical field [0001] The invention relates to the technical field of powder coating equipment, in particular to a vacuum powder pump control system for conveying powder. Background technique [0002] Powder spraying refers to a coating process that uses corona discharge to make powder coatings adhere to workpieces. After spraying the powder, it will form a coating film on the surface of the workpiece through steps such as hot melting and curing. [0003] In the powder spraying process, the first step is powder conveying. In the existing powder spraying process, the powder conveying is carried out by ordinary powder pump, that is, the powder is blown by compressed air. This conveying method exists in the process of use. The following deficiencies: [0004] 1. The powder conveying efficiency is low and the powder density is low (the conveyed powder contains a lot of compressed air); [0005] 2. Affect production efficiency; [0006] 3. No automatic cleaning function requ...
