Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, and in particular to an external mixing spray gun for a low-pressure air-supported and pressure-controlled two-component spraying device. Background Technology

[0002] As is well known, spraying equipment is a specialized tool used to uniformly spray liquid materials such as paint and coatings onto the surfaces of various objects. It plays a crucial role in many fields such as industrial production, building decoration, and automobile manufacturing and repair. Typically, in spraying equipment, paint is transported from a storage container through pipes under certain pressure to the spray gun.

[0003] However, traditional spray guns typically have only one feed channel in their internal structure, which can only allow one type of material. If multiple colors or materials need to be sprayed, the spray gun must be thoroughly cleaned each time it is changed to prevent different colors or materials from mixing and affecting the spraying effect. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-pressure, air-supported, two-component spraying equipment with an external mixing spray gun. When using this spray gun, the use of a two-component spray gun eliminates the need for frequent material changes. This spray gun allows for the simultaneous preparation of both components, eliminating the need for thorough cleaning of the spray gun after spraying one component, as is required with traditional spray guns, thus significantly reducing the time spent on material changes and spray gun cleaning, and improving the overall efficiency of the spraying operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A low-pressure air-supported and pressure-controlled two-component spraying device with an external mixing spray gun includes a grip, a connecting frame fixedly connected to the front end of the grip, and flow tubes penetratingly connected to both sides of the outer wall of the front end of the connecting frame. An adjuster is threadedly connected to the outer wall of the front end of each flow tube, and a spray head is penetratingly connected to the front end of each adjuster.

[0007] Compared with existing spray guns, the above technical solution allows for separate control of the flow rate of the two-component materials through the design of the flow pipe, regulator, and regulating valve. The regulator facilitates adjustment of the spraying angle, and the regulating valve allows for precise adjustment of the spraying amount of each component material according to actual spraying requirements.

[0008] Furthermore, a switch frame is hinged to the middle of the outer walls on both sides of the grip;

[0009] The above technical solution, through the switch frame, facilitates the delivery of coatings.

[0010] Furthermore, both sides of the lower surface of the connecting frame are connected through liquid inlet pipes, and the lower end of the liquid inlet pipes is threadedly connected to a delivery pipe.

[0011] The above technical solution facilitates the delivery of coatings to the inlet pipe via the delivery pipe.

[0012] Furthermore, regulating valves are provided on the outer wall of the opposite side of the spray head;

[0013] The above technical solution allows for easy adjustment of the spray size via a regulating valve.

[0014] This utility model has the following beneficial effects:

[0015] 1. The present invention proposes a low-pressure air-supported two-component spraying equipment with external mixing spray gun. Compared with existing spraying equipment spray guns, this spraying equipment spray gun eliminates the need for frequent material changes by using a two-component spray gun. Using this spray gun, both components can be prepared simultaneously, eliminating the need to thoroughly clean the spray gun after spraying one component before switching to the other component, as is the case with traditional spray guns. This greatly reduces the time spent on material changes and spray gun cleaning, and improves the overall efficiency of the spraying operation.

[0016] 2. The present invention proposes a low-pressure air-supported two-component spraying equipment external mixing spray gun. Compared with the existing spraying equipment spray guns, the design of the flow pipe, regulator and regulating valve of the spraying equipment spray gun allows the flow rate of the two-component materials to be controlled separately. The regulator facilitates the adjustment of the spraying angle, and the regulating valve can accurately adjust the spraying amount of each component material according to the actual spraying requirements.
