Description

Technical Field

[0001] The utility model relates to the technical field of jeans spraying equipment, in particular to a spray gun with adjustable spray volume. Background Art

[0002] A spray gun is a tool for spraying paint, used for surface treatment of products. It is a type of coating equipment. It uses compressed air to atomize the paint into fine paint droplets, which are then sprayed onto the surface of the object under the influence of the airflow. It has a wide range of applications. For example, in the production process of jeans, a spray gun is needed to spray the paint on the surface of jeans. For example, the jeans spraying equipment with reference number: 2024209903421, our company uses a spray gun to spray the surface of jeans.

[0003] Reference application number: 201621290345.6 is a multifunctional leather spraying device. The existing spray gun mainly includes a gun body, a gun nozzle, a gun core, a flow regulating valve and other parts. After the continuous development of the spray gun, the existing spray gun can already achieve automatic spraying, which is mainly based on the synergy of compressed air and paint supply system, and the atomization effect of the nozzle to achieve automatic spraying. However, whether it is a manual or automatic spray gun, the spray volume still needs to be manually adjusted, and the existing flow regulating valves are connected to the gun core. By manually twisting the flow regulating valve, the gun core is moved closer to or away from the nozzle, thereby achieving the adjustment of the spray volume. This results in that during the use of the jeans spraying equipment, whenever the spray volume needs to be changed, the equipment needs to be paused, the spray volume manually adjusted, and then the equipment is restarted for automatic spraying, which is very troublesome.
