Description

Technical Field

[0001] The utility model relates to the technical field of waste collection for spraying machines, in particular to a waste collection device for spraying machines. Background Art

[0002] A sprayer is a specialized coating device that utilizes spray technology, primarily used to disperse paint into a mist and apply it to surfaces. It primarily consists of a feeder, a spray gun, and an atomizer, and is suitable for applications in industries such as leather goods and handbags, gift packaging, furniture, footwear, and automotive manufacturing. The sprayer's operating principle is to control the airflow to momentarily reverse the direction of the air distribution reversing mechanism, causing the pneumatic motor's piston to perform a steady, continuous reciprocating motion. This pressurizes the incoming paint, which is then transported via a high-pressure hose to the spray gun, where it is instantly atomized and released onto the surface.

[0003] Sprayers can be categorized into various types, including electric airless sprayers, pneumatic airless sprayers, and internal combustion airless sprayers, depending on their power source and atomization method. Electric sprayers, however, have attracted widespread attention in the market for their high efficiency and environmental friendliness. These devices utilize an electric power source to disperse paint into a mist and apply it to the surface. They offer advantages such as high application efficiency, a smooth, even coating, strong adhesion, and a prolonged coating life.

[0004] At present, in the actual application of the waste collection device for sprayers, the collection device is fixedly installed at a designated position of the sprayer, and the collection mechanism is used to absorb and clean the waste air generated during the spraying process. However, the filter element of the collection mechanism is usually fixedly installed inside the collection device. When the collection device is used for a long time, a large amount of waste particles will adhere to the surface of the filter element. If it is not cleaned in time, the effectiveness of the collection device will be affected. Utility Model Content
