Abstract

Disclosed is a powder supply device for electrostatic spraying of a powder coating material, relating to the field of powder coating. The device comprises an outer housing. A feeding chamber is disposed in the outer housing, and a turnplate is rotatably disposed in the feeding chamber. A plurality of coating material storage containers are fixedly disposed on the turnplate. A feeding mechanism used to feed the coating material to a spray gun is provided at the storage containers. A material preparation cylinder used to configure different components of the coating material is fixedly disposed on a top surface of the outer housing. The preparation and supply of coating materials are separated such that each time a coating material has been conveyed from a storage container, the next storage container can immediately perform a material supply operation, thereby reducing intermediary manual operations and improving processing efficiency. When the majority of the coating material in a storage container has been conveyed, nozzles are used to blow the coating material up, so as to reduce the amount of coating material remaining in the storage container. A temporary storage box is provided to temporarily store the conveyed coating material therein, and enables the coating material in the temporary storage box to be stirred and screened, so as to reduce clogging of the spray gun.

Description

一种用于粉末涂料静电喷涂的供粉装置A powder supply device for electrostatic spraying of powder coatings 技术领域technical field
本发明属于粉末涂装领域，具体为一种用于粉末涂料静电喷涂的供粉装置。The invention belongs to the field of powder coating, in particular to a powder supply device for electrostatic spraying of powder coatings.
背景技术Background technique
静电喷涂是一项使用非常广泛的涂装技术，相对于一般的喷涂工艺，速递块，效率高，喷涂效果好，静电喷涂的粉末涂料被存储在一个储料罐内，由于在喷涂时，涂料直接通过管道进行输送，在输送涂料的时候，经过高压气体和静电场传送，而未被传送的涂料也会直接带电，非常不便于对储料罐内的粉末进行更换和添加，而且在高压气体传送的时候，一些粉末会因为粘接在一起对喷枪口产生堵塞。Electrostatic spraying is a very widely used coating technology. Compared with the general spraying process, the express block has high efficiency and good spraying effect. The powder coating of electrostatic spraying is stored in a storage tank. It is conveyed directly through the pipeline. When conveying the paint, it is conveyed through high-pressure gas and electrostatic field, and the paint that has not been conveyed will also be directly charged, which is very inconvenient to replace and add the powder in the storage tank. During delivery, some of the powder will clog the nozzle of the spray gun by sticking together.
目前的静电喷涂设备的供料装置都是通过单一的储料罐进行供应的，在储料罐内的涂料使用完之后，需要人工进行混合配置和添加，这也就导致在喷涂时效率降低，不方便持续供应涂料，特别是在无法对喷涂设备进行供料时，储料罐内还会残留有大量的余料，导致使用浪费。The feeding devices of the current electrostatic spraying equipment are all supplied through a single storage tank. After the paint in the storage tank is used up, it needs to be mixed, configured and added manually, which also leads to a decrease in the efficiency of spraying. It is inconvenient to continuously supply paint, especially when the spraying equipment cannot be supplied, a large amount of residual material will remain in the storage tank, resulting in waste of use.
发明内容SUMMARY OF THE INVENTION
本发明的目的是针对以上问题，提供一种用于粉末涂料静电喷涂的供粉装置，便于持续供料，减少储料罐内的余料残留。The purpose of the present invention is to address the above problems, and provide a powder supply device for electrostatic spraying of powder coatings, which is convenient for continuous supply of materials and reduces residual material residues in the storage tank.
