Description

Technical Field

[0001] This utility model relates to the field of automatic spray painting technology, and in particular to a mechanism for controlling and resolving automatic spray painting gun clogging. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets using pressure or centrifugal force, and then applies the coating to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivatives of the above basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying.

[0003] Currently, automatic paint spray guns apply paint to the surface of objects, preventing the paint from being inhaled by the human body. The nozzle, located at the mouth of the automatic paint spray gun, is the main component that sprays out the pressurized paint. However, this method presents the following problems in actual operation:

[0004] 1. In actual use, due to the accumulation of paint inside the nozzle, and the solidification of the paint inside the nozzle after solidification, the nozzle becomes blocked and cannot spray out the paint or the sprayed paint is unevenly distributed.

[0005] 2. Due to prolonged contact with outside air, the paint hardens and clogs the nozzle, causing blockage. The usual solution is to remove the nozzle from the front of the spray gun, rinse it with water, and use a rod to unclog it. After unclogging, the nozzle is screwed back on. This cleaning method is quite troublesome, requiring repeated manual removal, cleaning, and installation of the nozzle. Moreover, frequent removal and installation can cause wear on the nozzle mounting location, leading to loosening and air leakage, which affects the service life of the spray gun. Summary of the Invention

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a mechanism for controlling and solving the blockage of automatic paint spray guns, so as to solve the technical problems that the nozzle of the current paint spray gun is easily blocked by solidified paint, and the repeated disassembly of the paint spray gun head is prone to causing severe wear and tear on the nozzle, and easy loosening and air leakage.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A mechanism for controlling and resolving automatic paint spray gun clogging includes a spray gun body, an anti-clogging mechanism for the spray gun body is fixedly installed on the inner surface of the spray gun body, and a quick-release mechanism for the spray gun head is fixedly installed on the outer surface of the spray gun body.

[0010] The spray gun anti-clogging mechanism includes a partition, the outer surface of which is fixedly connected to the inner surface of the spray gun body. A connecting pipe is fixedly installed on the left side of the partition, and an air inlet pipe is connected to the outer surface of the connecting pipe. The right end of the air inlet pipe is connected to the left side of the partition.

[0011] As an improved technical solution, the spray gun anti-clogging mechanism also includes a valve core, the outer surface of which is slidably connected to the inner surface of the air inlet pipe, a spring is fixedly installed on the right side of the valve core, the right end of which is fixedly connected to the inner wall of the air inlet pipe, and an air jet hole is formed through the outer surface of the valve core.

[0012] As an improved technical solution, the spray gun anti-clogging mechanism also includes an electromagnetic coil, the inner surface of which is fitted onto the outer surface of the air inlet pipe.

[0013] As an improved technical solution, the quick-release mechanism for the gun head includes a gun head, the inner surface of which is engaged with the outer surface of the spray gun body, a connecting block is fixedly installed on the outer surface of the gun head, and a locking rod is fixedly installed on the right side of the connecting block.

[0017] As an improved technical solution, the outer surface of the gun head is connected to a feed pipe, and a valve is fixedly installed on the outer surface of the feed pipe.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are:

[0019] 1. This utility model improves the design by enhancing the cleaning of residual paint inside the spray gun.

This avoids repeated disassembly of the spray head, which can easily cause severe wear and tear, leading to loosening and air leakage. Attached Figure Description

The right end of the air inlet pipe 23 is connected to the left side of the partition 21.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the spray gun anti-clogging mechanism 2 also includes a valve core 24. The outer surface of the valve core 24 is slidably connected to the inner surface of the air inlet pipe 23. A spring 25 is fixedly installed on the right side of the valve core 24. The right end of the spring 25 is fixedly connected to the inner wall of the air inlet pipe 23. An air jet hole 26 is opened through the outer surface of the valve core 24.

[0036] like Figure 2 and Figure 3 As shown, the spray gun anti-clogging mechanism 2 also includes an electromagnetic coil 27, the inner surface of which is fitted onto the outer surface of the air inlet pipe 23.

[0037] The electromagnetic coil 27 is electrically connected to an external power supply and is controlled by an external PLC programming program.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, the quick-release mechanism 3 for the gun head includes a gun head 31. The inner surface of the gun head 31 is engaged with the outer surface of the spray gun body 1. A connecting block 32 is fixedly installed on the outer surface of the gun head 31, and a locking rod 33 is fixedly installed on the right side of the connecting block 32.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, the quick-release mechanism 3 for the gun head also includes a connecting box 34. A fixing component 35 is fixedly installed on the inner surface of the connecting box 34. The fixing component 35 includes a first worm gear 351. The outer surface of the first worm gear 351 is rotatably connected to the inner surface of the connecting box 34. A turntable 352 is fixedly installed on the top end of the first worm gear 351.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, the fixing assembly 35 also includes a second worm gear 353, the two ends of which are rotatably connected to the inner surface of the connecting box 34, and a first worm wheel 354 is fixedly installed on the outer surface of the second worm gear 353. The outer surface of the first worm wheel 354 is threadedly connected to the outer surface of the first worm gear 351.

[0041] like Figure 1 , Figure 4 and Figure 5As shown, the fixing assembly 35 also includes a threaded rod 355, the outer surface of which is rotatably connected to the inner surface of the connecting box 34, a second worm gear 356 is fixedly installed on the outer surface of the threaded rod 355, the outer surface of the second worm gear 356 meshes with the outer surface of the second worm 353, and a bracket 357 is provided on the outer surface of the threaded rod 355 away from the second worm gear 356.

[0043] Valve 5 is electrically connected to an external power source and is controlled by an external PLC programming program.

[0044] During use, high-pressure gas flows inside the spray gun body 1. When the spray gun is in use, valve 5 opens, and paint enters the nozzle 31 through the feed pipe 4. The solenoid coil 27 is energized, generating magnetic force that moves the valve core 24 into the solenoid coil 27. This aligns the air jet 26 within the valve core 24 with the air inlet pipe 23, allowing gas from the spray gun body 1 to enter the air jet 26 through the air inlet pipe 23 and exit from the air jet 26, thus spraying the paint out by the high-pressure gas. When the paint is not being sprayed, valve 5 closes, and the solenoid coil 27 is periodically energized and de-energized, causing the valve core 24 to move through the spring 25. High-pressure gas is sprayed in a flash to clean the paint residue inside the nozzle 31. When the nozzle 31 needs to be disassembled and installed, the operator rotates the turntable 352. The turntable 352 drives the first worm wheel 354 to rotate through the first worm 351. The first worm wheel 354 drives the second worm wheel 356 to rotate through the second worm 353. The second worm wheel 356 drives the clamp 357 to move outward through the threaded rod 355, so that the clamp 357 is disengaged from the clamp rod 33, allowing the nozzle 31 to be removed from the spray gun body 1 for easy cleaning. The nozzle 31 can be installed back onto the spray gun body 1 by reversing the operation.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
