Structurally-improved pneumatic airless spray machine

Abstract

The invention provides a structurally-improved pneumatic airless spray machine, and belongs to the field of spraying equipment. The pneumatic airless spray machine comprises a machine body, wherein the machine body is arranged on a rack body; four rollers are arranged at the bottom of the rack body; the rack body is connected with a spray gun through a high-pressure hose; the spray gun comprises a gun body; the gun body is connected with the high-pressure hose through a hose connector. In the working process, a connecting rod of the pneumatic airless spray machine can move smoothly and stably, and then the rack body with the four rollers can roll conveniently and move to an appropriate operation position; the spray gun connected through the high-pressure hose can move conveniently, the operation is convenient, and the spraying efficiency can be improved.

Description

technical field [0001] The invention relates to the field of spraying equipment, in particular to a high-pressure airless spraying machine with an improved structure. Background technique [0002] High-pressure airless spraying (referred to as airless spraying), which can be divided into single and double (multiple) components, has been widely used in the construction industry in Europe, America and other countries. Different from air spraying, high-pressure airless spraying is a process that does not need compressed air to atomize the paint, but applies high pressure to the corresponding paint to atomize the paint when it is sprayed. The working principle of the high-pressure airless sprayer is to continuously transport paint into the closed paint pipeline through the high-pressure plunger pump, thereby forming a high pressure (usually 11MPa-25MPa) in the pipeline in the confined space. Then loosen the trigger of the spray gun connected to the end of the paint tube to forc...

AI Technical Summary

Problems solved by technology

[0009] However, the high-pressure airless spraying machine is not used for small workpieces, and the amount of paint sprayed and the width of the spray width cannot be adjusted.

At the same time, the pressure and speed of spraying are large, which can cause damage to the skin, and compared with air spraying, the cost investment of its equipment is relatively high

[0010] The structure design of the traditional high-pressure airless spraying machine is unreasonable, and the practicality is not convenient enough
