Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying equipment, in particular to a pneumatic paint spraying device. Background Art

[0002] A paint spray gun is a tool for spraying paint. It is used for surface treatment of products and is a type of coating equipment. It uses compressed air to atomize the paint into tiny paint droplets, which are sprayed onto the surface of the object under the drive of the airflow. It is mainly composed of a spray cap, nozzle, needle valve and gun body.

[0003] After searching, the patent number is CN218340075U, and the name is a utility model of a paint spray gun with an adjustable paint canister, which includes a paint spray gun body and an adjustable paint canister assembly. Through research and analysis, it is found that although the setting of the corrugated connecting barrel and the adjustable telescopic part during use can reduce the frequent disassembly and filling when spraying a larger area, and improve the spraying efficiency, etc., however, there are still the following disadvantages to a certain extent.

[0004] For example, the device does not have a limit function. During use, the adjustment knob on the surface of the paint spray gun cannot be limited, which causes the internal components of the paint spray gun to age easily during long-term use, and then causes the adjustment knob to rotate, thereby affecting subsequent painting work. In order to solve the above technical problems, we have designed a pneumatic paint spraying device. Utility Model Content

[0005] The utility model aims to provide a pneumatic paint spraying device, which has the advantages of limiting function and anti-sedimentation function, and solves the problem that the existing paint spray gun cannot limit and fix the adjustment knob during use and does not have the anti-sedimentation function.

[0007] Preferably, the air supply mechanism comprises an air supply pipe, the left side of the air supply pipe is connected to the air inlet pipe, the right end of the air supply pipe is connected to the connecting pipe, and a manual valve is fixedly installed on the surface of the air supply pipe.

[0008] Preferably, the limiting mechanism includes a spring, the opposite ends of the spring are fixedly connected to the partition, the opposite ends of the spring are fixedly connected to a movable plate, the right side of the movable plate is riveted with an adjustment plate, the opposite side of the movable plate is riveted with a limiting plate, and the opposite side of the limiting plate passes through the limiting frame and engages with the adjusting knob.

[0009] Preferably, rectangular holes are provided at the top and bottom of the right side of the limiting frame, and the right side of the adjusting plate passes through the rectangular hole.

[0010] Preferably, the bottom of the pot cover is connected to a paint supply tube, and the bottom end of the paint supply tube extends to the inner cavity of the cylinder.

[0011] Preferably, there are several stirring blades, and the stirring blades are arranged at equal distances.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model has the advantage of a limiting function through the cooperation of a limiting frame, a partition and a limiting mechanism. The limiting plate is engaged with the adjusting knob to prevent it from rotating. When the adjusting knob needs to be rotated, the adjusting plate is pulled, and the adjusting plate drives the movable plate to move. The compression spring of the movable plate drives the limiting plate to move, and one end of the limiting plate moves away from the adjusting knob, thereby releasing the limit on the adjusting knob, and then the adjusting knob is rotated.

[0014] 2. The utility model has the advantage of anti-sedimentation function through the cooperation of the cylinder, filter holes, stirring blades, blades, air inlet pipe, exhaust pipe and air supply mechanism. The manual valve is rotated, and the compressed gas is transported to the inner cavity of the sealing cover through the air supply pipe and the air inlet pipe. The compressed gas blows the blades, and the excess air circulates once and is discharged to the outside of the sealing cover through the exhaust pipe. The blades drive the cylinder and the stirring blades to rotate, thereby stirring the paint so that it will not precipitate. BRIEF DESCRIPTION OF THE DRAWINGS
