Description

Technical Field

[0001] The utility model relates to the technical field of spray gun docking, in particular to a rapid docking device for the outlets of two-component raw materials. Background Technique

[0002] The two-component spraying machine is an important machine in polyurethane foam production and is used in cooperation with a spray gun.

[0003] The two-component raw materials are mixed and reacted in the spray gun and then sprayed onto the working surface to complete foaming. After a single operation, polyurethane foam will inevitably remain in the spray gun, which will cause the spray gun to be blocked. In severe cases, the spray gun cannot be used. It is necessary to disassemble, clean, repair or replace the spray gun.

[0004] During the process of shutting down for disassembly and repair, the raw materials remaining in the pipeline cause great trouble to disassembly and cleaning, and also result in waste and environmental pollution. Content of the Utility Model

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A rapid docking device for the outlets of two-component raw materials, including an upper valve body and a lower valve body; the upper valve body and the lower valve body are used to support device components, and the upper valve body and the lower valve body are provided with: grooves, bumps, threaded holes, fixing bolts and raw material transmission control components;

[0006] Among them, the raw material transmission control components include: a spraying machine pipeline joint, a spray gun joint, a material conveying pipe, a needle valve, a discharge port, a connecting pipe, a docking head and a docking groove;

[0007] The discharge port is opened at the bottom of the upper valve body and the top of the lower valve body. The needle valve is installed at the bottom of the upper valve body and behind the lower valve body. The material conveying pipe is connected between the front ends inside the upper valve body and the lower valve body and the needle valve. The spraying machine pipeline joint and the spray gun joint are installed in front of the upper valve body and the lower valve body and are connected to the front end of the material conveying pipe. The connecting pipe is connected between the needle valve and the discharge port. The docking head is installed at the discharge port of the upper valve body, and the docking groove is opened at the discharge port at the top of the lower valve body. Through this component, the conveyance and control of the spray gun raw materials can be carried out, so as to ensure that the temperature and pressure in the spraying machine pipeline remain unchanged when the spray gun is disassembled.

[0008] Preferably, two groups of the raw material transmission control components are provided.

[0009] Preferably, the control end of the needle valve extends out of the surfaces of the upper valve body and the lower valve body.

[0010] Preferably, a sealing ring is provided on the docking head.

[0011] Beneficial Effects

[0012] The present rapid butt-joint device for the outlet of two-component raw materials has the following beneficial effects:

[0013] This case is installed between the pipeline of a two-component spraying machine and the spray gun. Through the raw material transmission control component, when the spray gun is disassembled and cleaned, first close the four needle valves of this device to keep the raw materials in the pipeline, which can ensure that the temperature and pressure in the pipeline of the spraying machine remain unchanged when the spray gun is disassembled. Loosen the bolts fixing the upper and lower valve blocks and separate the upper and lower valve blocks; open the two needle valves of the upper valve block respectively, and introduce the raw materials of the two components in the upper valve block into the designated positions for storage; after there is no raw material residue in the spray gun, carry out the disassembly and cleaning work.

[0019] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution.

[0021] A rapid butt-joint device for the outlet of two-component raw materials includes an upper valve body 1 and a lower valve body 2; the upper valve body 1 and the lower valve body 2 are used to support the device components, and the upper valve body 1 and the lower valve body 2 are provided with: a groove 3, a convex block 4, a threaded hole 5, a fixing bolt 6, and a raw material transmission control component;

[0022] Among them, the raw material transmission control component includes: a spraying machine pipe joint 7, a spray gun joint 8, a feeding pipe 9, a needle valve 10, a discharge port 11, a connecting pipe 12, a docking head 13 and a docking groove 14;

[0023] The discharge port 11 is opened at the bottom of the upper valve body 1 and the top of the lower valve body 2. The needle valve 10 is installed at the bottom of the upper valve body 1 and behind the lower valve body 2. The feeding pipe 9 is connected between the front ends inside the upper valve body 1 and the lower valve body 2 and the needle valve 10. The spraying machine pipe joint 7 and the spray gun joint 8 are installed in front of the upper valve body 1 and the lower valve body 2 and connected to the front end of the feeding pipe 9. The connecting pipe 12 is connected between the needle valve 10 and the discharge port 11. The docking head 13 is installed at the discharge port 11 of the upper valve body 1. The docking groove 14 is opened at the discharge port 11 at the top of the lower valve body 2.

[0024] It should be noted that when the nozzle is working, connect the spraying machine pipe to the spraying machine pipe joint 7 and connect the spray gun to the spray gun joint 8. Subsequently, the raw material can complete the raw material transmission through the feeding pipe 9 and the opened needle valve 10. When it is necessary to disassemble the paint sprayer, close the needle valve 10 to stop the raw material transmission. Then, after removing the fixing bolts 6, the upper valve body 1 and the lower valve body 2 can be separated, so that the spray gun connected to the upper valve body 1 and the lower valve body 2 can be separated. Then, open the needle valve 10 in the upper valve body 1 to discharge the raw material in the components in the upper valve body 1. Then, the nozzle can be separated from the upper valve body 1 to clean the nozzle, and this process will not be affected.
