[0001] The invention relates to the technical field of spraying equipment, and in particular to a spray gun mounting adapter. Background Art

[0002] The spray gun adapter is an installation product that connects the paint spray gun and the robot arm motion module. The internal flow channel is specially designed so that it can correspond to the fluid inlet and outlet of the specified spray gun product with a special appearance structure. At the same time, it is easy to disassemble and assemble, and the structure setting of the inclined surface of the installation surface allows the spray gun to meet various spraying angles.

[0003] The existing spray gun mounting adapter has a relatively simple function and only supports basic installation support. Adding subsequent module functions increases assembly difficulty and maintenance steps. Summary of the invention

[0004] The main purpose of the present invention is to provide a spray gun mounting adapter, which aims to solve the technical problem of reducing the subsequent installation of the spray gun module system and the complexity of external installation of the equipment, while saving solvent usage and facilitating maintenance, and providing more margin space for the rear mechanism.

[0005] In order to achieve the above-mentioned object of the invention, the first aspect of the present invention provides a spray gun mounting adapter, the adapter comprising:

[0006] Flange structure, used for connection with the mounting base;

[0007] The front end face has an inclined surface, and the inclined surface serves as a sealing surface for mounting with the spray gun;

[0008] Three color-changing one-way valve installation positions are provided on both sides of the adapter, and the installation positions are marked with identification numbers 1 to 6;

[0009] The bottom is provided with three threaded holes for fixing the mixing plate assembly;

[0010] The interior is provided with interlaced but mutually unconnected flow channels, which include but are not limited to a solvent cleaning port (A), a catalyst feed port (B), a main agent feed port (C), an air cleaning port (D), a main agent quick discharge port (E), a catalyst quick discharge port (F), a one-way valve opening port (J, L, G, K, M, I), and an atomizing nozzle (O), a fan nozzle (N) and a switch gun air inlet (H) of a spray gun (3).

[0011] Furthermore, a total of 15 marks from A to O are engraved on the back mounting surface of the adapter, which respectively correspond to hoses of different media channels, and the flow channels lead to different installation positions of the one-way valve.

[0012] Furthermore, an inlet for the spray gun and an outlet are provided on the end surface of the adapter, and the inlet for the spray gun and the outlet are respectively connected to corresponding hoses.

[0013] Furthermore, in the normal working state, only the catalyst feed port (B) and the main agent feed port (C) of the adapter are opened, and air is introduced through the corresponding one-way valve opening ports (L, K) to open the one-way valve, while the one-way valve positions (5, 6) are in a closed state.

[0014] Furthermore, in the cleaning mode, the one-way valves (2, 4) are closed, the catalyst quick discharge channel (F) and the main agent quick discharge channel (E) are opened, and air is introduced through the one-way valve opening ports (M, I) to open the one-way valves (5, 6), so that the catalyst and the main agent are quickly discharged from the quick discharge ports.

[0015] Furthermore, in the cleaning mode, the solvent cleaning port (A) and the air cleaning port (D) are opened, and air is introduced through the one-way valve opening port (G, J) to open the one-way valve (3, 1), and the air and the cleaning agent are alternately introduced into the spray gun for cleaning.

[0016] Furthermore, in the normal working mode of the flow channel of the adapter, the catalyst (B) and the main agent (C) can be mixed in the adapter and discharged to the solvent mixing plate through the bottom outlet, and after further mixing with the mixing core in the mixing plate, enter the spray gun upward from the head position of the adapter.

[0017] Furthermore, the one-way valve (1-6) structure of the adapter can be opened or closed by controlling the air supply, thereby realizing the fluid guiding function in different working modes, including but not limited to fluid mixing and spraying in the normal working mode, and rapid fluid discharge and spray gun cleaning in the cleaning mode.

[0018] Furthermore, two ends of the main channel at the bottom of the adapter are connected, and the two ends of the main channel are connected for cleaning and maintenance. In a non-working state, a sealing plug is used to seal the plug hole to prevent impurities from entering.

[0019] Furthermore, the cooperation between the front sealing surface of the adapter and the spray gun ensures tightness and sealing of the installation, preventing leakage during the spraying process.

[0020] Beneficial effects:

[0038] Reference Figure 1-Figure 5 An embodiment of the present invention provides a spray gun mounting adapter, the adapter 1 comprising:

[0039] The flange structure 11 is used to connect with the mounting base 4;

[0040] The front end face has an inclined surface 12, and the inclined surface 12 serves as a sealing surface for mounting and cooperating with the spray gun 3;

[0041] Three color-changing one-way valve installation positions 13 are provided on both sides of the adapter, and the installation positions 13 are marked with identification numbers 1 to 6;

[0042] The bottom is provided with three threaded holes 17 for fixing the mixing plate assembly 2, and screws are used to connect the mixing plate assembly 2 through the three threaded holes 17;

[0043] There are staggered but non-interconnected flow channels inside, which include but are not limited to solvent cleaning port A, catalyst feed port B, main agent feed port C, air cleaning port D, main agent quick discharge port E, catalyst quick discharge port F, one-way valve opening ports J, L, G, K, M, I and atomizing nozzle O, fan nozzle N and switch gun air inlet H of the spray gun 3.

[0044] In this embodiment, the adapter 1 is an integral structural member made of metal material, and its appearance and structure are compact and reasonable, ensuring good adaptability in a small space. The back structure of the adapter 1 is provided with a flange structure 11, and the flange structure 11 is provided with a plurality of bolt holes for fixed connection with the mounting base 4 of the spray system. In order to ensure the stability and sealing of the connection, auxiliary components such as sealing rings can be added between the flange structure 11 and the mounting base 4. The front end face of the adapter 1 is provided with a bevel 12, and the bevel 12 serves as a sealing surface, which matches the interface of the spray gun 3, ensuring the tightness and sealing performance of the two during installation. In addition, in order to facilitate operators to identify different flow channels and functions,

[0045] The internal structure of the adapter 1 is provided with a plurality of interlaced but unconnected flow channels, each of which has a clear functional orientation. Among them, the solvent cleaning port A is used to introduce the cleaning solvent, the catalyst feed port B and the main agent feed port C are used to introduce the catalyst and the main agent material respectively, and the air cleaning port D is used to introduce the cleaning air. In addition, it also includes the main agent quick discharge port E and the catalyst quick discharge port F, which are used to quickly discharge the residue in the cleaning mode.

[0046] The flow channels are connected to the one-way valves 2, 4, 5, and 6 through the one-way valve opening ports J, L, G, K, M, and I, ensuring the directional flow of the fluid. The working fluid of the spray gun 3 will eventually be output through the atomizing nozzle O, the fan nozzle N, and the switch gun air inlet H to complete the spraying operation.

[0047] Optionally, the back mounting surface of the adapter 1 is engraved with 15 marks from A to O, which correspond to the hoses 5 of different media channels, and the flow channels lead to different positions of the installation position 13 of the one-way valve. The back mounting surface of the adapter 1 is engraved with 15 marks from A to O, each mark corresponds to the connection point of the hose 5 of different media channels, which facilitates the correct connection of the hose.

[0048] In one embodiment, an inlet port 14 and an outlet port 15 are formed on the end surface of the adapter 1 , and the inlet port 14 and the outlet port 15 are respectively connected to the corresponding hose 5 .

[0049] In the normal working state, only the catalyst feed port B and the main agent feed port C of the adapter 1 are open, and air is introduced through the corresponding one-way valve opening ports L and K to open the one-way valve, while the one-way valve positions 5 and 6 are in the closed state.

[0050] When the adapter 1 is in normal working mode, the catalyst B and the main agent C are mixed in the adapter 1 and flow to the mixing plate assembly 2 through the bottom outlet. In the mixing plate assembly 2, the mixed liquid is fully in contact with the mixing core to ensure a uniform mixing effect. Subsequently, the mixed liquid enters the spray gun 3 upward through the head position of the adapter 1 to achieve the spraying operation.

[0051] Six one-way valves 1-6 are arranged in the adapter 1, which are respectively located at the installation positions 13 of the three color-changing one-way valves on both sides of the adapter 1. The one-way valve has an ingenious structure and can be opened or closed by controlling the air flow, thereby guiding the fluid in different working modes. For example, in the normal working mode, the catalyst feed port B and the main agent feed port C are open, and the one-way valves 5 and 6 are in a closed state; while in the cleaning mode, the one-way valves 5 and 6 are opened, and the catalyst quick discharge flow channel F and the main agent quick discharge flow channel E are opened to achieve rapid discharge.

[0052] In one embodiment, in the cleaning mode, the one-way valves 2 and 4 are closed, the catalyst quick discharge flow channel F and the main agent quick discharge flow channel E are opened, and air is introduced through the one-way valve opening ports M and I to open the one-way valves 5 and 6, and the catalyst and the main agent are quickly discharged from the quick discharge ports. In the cleaning mode, the solvent cleaning port A and the air cleaning port D are opened, and air is introduced through the one-way valve opening ports G and J to open the one-way valves 3 and 1, and the air and the cleaning agent are alternately introduced into the spray gun 3 for cleaning.

[0053] When the adapter 1 needs to be cleaned, it can be switched to the cleaning mode. At this time, the one-way valves 2 and 4 are closed, the catalyst quick discharge flow channel F and the main agent quick discharge flow channel E are opened, and air is introduced through the one-way valve opening ports M and I to open the one-way valves 5 and 6, so that the catalyst and the main agent are quickly discharged from the quick discharge ports. At the same time, the solvent cleaning port A and the air cleaning port D are opened, and air is introduced through the one-way valve opening ports G and J to open the one-way valves 3 and 1, and the air and cleaning agent are alternately introduced into the spray gun 3 to clean the spray gun 3 comprehensively.

[0054] When the flow channel of the adapter 1 is in normal working mode, the catalyst B and the main agent C can be mixed in the adapter 1 and discharged to the solvent mixing plate through the bottom outlet, and then further mixed with the mixing core in the mixing plate and enter the spray gun 3 upward from the head position of the adapter 1.

[0055] In one embodiment, the one-way valve 1-6 structure of the adapter 1 can be opened or closed by controlling the air supply, thereby realizing the fluid guiding function in different working modes, including but not limited to fluid mixing and spraying in the normal working mode, and rapid fluid discharge and spray gun 3 cleaning in the cleaning mode.

[0056] In one embodiment, the two ends of the main flow channel at the bottom of the adapter 1 are connected, and the two ends of the main flow channel are connected for cleaning and maintenance. In a non-working state, a sealing plug is used to seal the plug hole 16 to prevent impurities from entering.

[0057] The two ends of the main flow channel at the bottom of the adapter 1 are connected. This structural setting not only facilitates cleaning and maintenance, but also facilitates sealing with a sealing plug through the plug hole 16 position when not in operation, to prevent impurities from entering the flow channel and affecting the normal progress of subsequent work.

[0058] The cooperation between the front sealing surface of the adapter 1 and the spray gun 3 ensures the tightness and sealing of the installation, preventing leakage during the spraying process.

[0059] In summary, the flow channel structure setting of the spray gun 3 mounting adapter 1 has the following characteristics:

[0060] The flow channel structure inside the adapter 1 is arranged to be staggered, but the various flow channels are not interconnected, which means that different fluids such as catalysts, main agents, cleaning solvents, etc. have different dedicated channels inside, thus avoiding mutual contamination or improper mixing.

[0061] The flow channel system includes but is not limited to solvent cleaning port A, catalyst feed port B, main agent feed port C, air cleaning port D, main agent quick discharge port E, catalyst quick discharge port F, one-way valve opening ports J, L, G, K, M, I, and atomizing nozzle O, fan nozzle N and switch gun air inlet H of the spray gun 3. Such a structural setting ensures the correct guidance of the fluid in various working modes.

[0062] The adapter 1 is provided with a plurality of one-way valve openings, through which the one-way valve is opened and closed, thereby realizing the selective opening or closing of different flow channels. The installation position 13 of the one-way valve is provided with identification numbers 1 to 6 for easy identification and management. The main flow channel at the bottom of the adapter 1 is connected at both ends, and this structural setting is conducive to cleaning the flow channel during cleaning and maintenance. In the non-working state, the plug hole 16 is sealed with a sealing plug to prevent external impurities from entering the flow channel.

[0063] In normal working mode, catalyst B and main agent C are mixed inside adapter 1, and then discharged to mixing plate assembly 2 through the bottom outlet, further mixed with the mixing core, and finally enter spray gun 3 from the head position of adapter 1 for spraying.

[0064] In the cleaning mode, the solvent cleaning port A and the air cleaning port D are opened, and air is introduced through the one-way valve opening ports G and J to open the one-way valves 3 and 1, and the air and the cleaning agent are alternately introduced into the spray gun 3 to clean the inside of the spray gun 3 and the flow channel of the adapter 1.

[0065] A total of 15 marks from A to O are engraved on the mounting surface at the back of the adapter 1, each mark corresponds to a different medium channel hose 5, ensuring the correct connection between the flow channel and the external hose. The inclined surface 12 on the front face of the adapter 1 serves as a sealing surface, which fits tightly with the interface of the spray gun 3 to ensure that no leakage occurs during the spraying process.

[0066] Note: Under normal working conditions, the working principle of the spray gun 3 mounting adapter 1 is as follows:

[0067] The catalyst is input into the adapter 1 through the catalyst feed port B, and the main agent is input into the adapter 1 through the main agent feed port C. Air is introduced through the corresponding one-way valve opening ports L and K to open the one-way valve, allowing the catalyst and the main agent to flow through.

[0068] Inside the adapter 1, the catalyst B and the main agent C are mixed in the adapter 1 and then discharged through the bottom outlet to the mixing plate assembly 2. The mixed fluid is further mixed with the mixing core in the mixing plate.

[0069] Finally, the mixed liquid passes through the head of the adapter 1 and enters the atomizing nozzle O or the fan nozzle N of the spray gun 3, ready for spraying.

[0070] The switch gun air inlet H provides the compressed air required to operate the spray gun 3, and is used to control the opening and closing of the spray gun 3. The atomizing nozzle O and the fan nozzle N are where the fluid finally passes through. The spray gun 3 sprays the mixed fluid in a suitable form through these two nozzles to meet different spraying requirements.

[0071] The flow channel structure setting inside the adapter 1 ensures that the catalyst and the main agent can be mixed in the adapter 1, and discharged to the solvent mixing plate through the bottom outlet, and then enter the spray gun 3 from the mixing plate. The structural setting of the main channel at both ends is convenient for cleaning and maintenance, but in the non-working state, the plug hole 16 is closed with a sealing plug to prevent impurities from entering. The inclined surface 12 at the front end of the adapter 1 serves as a sealing surface, which fits tightly with the interface of the spray gun 3 to ensure that no leakage occurs during the spraying process. The adapter 1 is connected to the mounting base 4 through the flange structure 11 to ensure the stability of the installation.

[0072] Through the above working principle, the spray gun 3 is installed with the adapter 1 to achieve accurate mixing and delivery of the catalyst and the main agent during the spraying process, while ensuring the safety of the operation of the spray gun 3 and the consistency of the spraying quality. The structural setting of the adapter 1 not only takes into account the needs of the spraying operation, but also takes into account the ease of maintenance and service life of the equipment.

[0073] In cleaning mode, the spray gun 3 mounting adapter 1 works as follows:

[0074] When the cleaning mode is started, the one-way valves 2 and 4 corresponding to the normal working mode are closed to prevent the entry of the working fluid. At the same time, the catalyst quick discharge flow channel F and the main agent quick discharge flow channel E are opened, and compressed air is introduced through the one-way valve opening ports M and I, so that the one-way valves 5 and 6 are opened, which can prompt the catalyst and the main agent to be quickly discharged from their respective quick discharge ports, reduce the substances remaining in the adapter 1, and improve the cleaning efficiency.

[0075] In the cleaning mode, the solvent cleaning port A and the air cleaning port D are opened, allowing the cleaning solvent and compressed air to enter the inside of the adapter 1. Air is introduced through the one-way valve opening ports G and J to open the one-way valves 3 and 1, thereby guiding the cleaning solvent and air into the spray gun 3. This alternating flow helps to remove the residue inside the spray gun 3 and keep the spray gun 3 clean. The operation in the cleaning mode is achieved by controlling the opening or closing of different one-way valves, with the aim of allowing the cleaning liquid and air to flow along a preset path to achieve the best cleaning effect. After the cleaning is completed, you can check again whether there is any residue inside the adapter 1, and repeat the cleaning process as needed until the spray gun 3 is completely clean.

[0076] The staggered but non-interconnected flow channel structure setting inside the adapter 1 supports the effective operation of the cleaning mode, ensuring that the cleaning liquid and air can reach all parts that need to be cleaned and can be discharged smoothly, avoiding the existence of dead corners.

[0077] In the cleaning mode, the spray gun 3 mounting adapter 1 introduces cleaning fluid and air by changing the state of the one-way valve and utilizing a specific flow channel layout to achieve thorough cleaning of the spray gun 3 and its related components, thereby ensuring long-term stable operation of the spray system.

[0078] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
