Description

Technical Field

[0001] The utility model belongs to the technical field of spray guns, and in particular relates to a multi-component spray gun used for spraying polyurethane fast-solidifying materials. Background Art

[0002] A general term for macromolecular compounds containing repeated carbamate groups on the main chain of polyurethane rapid solidification materials, which are formed by the addition polymerization of organic diisocyanates or polyisocyanates and dihydroxy or polyhydroxy compounds. When in use, polyurethane needs to be sprayed on the surface of the object in use, usually by spraying with a spray gun, and the existing spray gun is a device used for spraying polyurethane rapid solidification materials. When the spray gun is in use, it enters the internal multi-component spray of two grouped fluid channels through a connector, enters the interior of a mixing mechanism again through the two grouped fluid channels, and the mixing mechanism mixes the polyurethane, and then sprays it out to the outside through the spray hole again, which is convenient for the spray gun multi-component spraying;

[0003] When the existing spray gun is used to spray polyurethane fast-setting materials, the feed pipe of the spray connection is directly clamped on the surface of the connecting head and fixed again by a fastening hoop. Therefore, it is not convenient to reinforce the connecting head between the end of the connecting pipe and the end of the spray gun after fixed installation. Combined with the gravity of the feed pipe itself, the continuous movement of the spray gun during hand-held spraying causes the connecting pipe to shake unstably at the end of the connecting head. Long-term shaking can easily cause the end of the connecting pipe to be unstable or even damaged and fall off, affecting the fixation of the feed pipe and the connecting head when the spray gun is spraying polyurethane fast-setting materials. For this reason, the utility model proposes a multi-component spray gun for spraying polyurethane fast-setting materials. Utility Model Content

After entering the mixing mechanism 108, the polyurethane is mixed and then sprayed out to the outside through the spray hole 109 again. The spray gun body 100 is also provided with:

[0026] A reinforcement connection mechanism is provided, and the reinforcement connection mechanism includes a connection component arranged at the middle position of one end of the lower surface of the main gun body 101, and two reinforcement installation components are arranged at the bottom end of the connection component. After the feed pipe and the connecting head 105 are fixedly installed, the end of the feed pipe and the end of the main gun body 101 are reinforced and fixedly connected by the reinforcement connection mechanism.

[0027] In order to facilitate the installation of the mounting ring 1051 through the connecting assembly and to reinforce the installation of the feed pipe, in the present embodiment, preferably, the connecting assembly includes a flexible suspension rod 1052 fixed to the lower surface of one end of the main gun body 101 by screws, and the end of the flexible suspension rod 1052 is integrally formed with a connecting piece 1053, and both ends of the connecting piece 1053 are fixed with mounting rings 1051 by screws, so that the mounting ring 1051 can be conveniently installed through the flexible suspension rod 1052 and the connecting piece 1053, and the feed pipe can be reinforced and installed inside the mounting ring 1051, so that it is convenient to fix and install it for use.

[0029] An isolation and protection mechanism is provided, and the isolation and protection mechanism includes an isolation and protection component arranged at the end of the main gun body 101 and located on the outer surface of the nozzle 104. A rotating mounting component is arranged in the middle position of the isolation and protection component. When the spray gun main body 100 generates splashes when spraying materials, the isolation and protection mechanism can protect the hands, and the splashed materials are not easy to adhere to the hands, thereby improving the isolation and protection effect of the spray gun main body 100 when spraying polyurethane rapid-solidification materials.

[0030] In order to facilitate the isolation and protection of the hands when the spray gun main body 100 is spraying through the isolation and protection component, and not easily cause the material to splash on the hands, in this embodiment, preferably, the isolation and protection component includes a protective cover 1041 arranged at the end of the main gun body 101 on the outer surface of the nozzle 104, and the inner surface of the protective cover 1041 is an arc structure. When splashing occurs when the spray gun main body 100 sprays materials, the protective cover 1041 isolates and protects the hands and the nozzle 104, which facilitates isolation and protection when spraying materials and is not easy to splash.

[0032] The working principle and use process of the utility model are as follows: when using the multi-component spray gun for spraying polyurethane fast-solidifying materials, the air quick-connect hose 102 can be connected to the external air inlet pipe, the connector 105 can be connected to the external polyurethane feed pipe, the handle 103 can be held and the trigger 106 can be pulled to open the cleaning rod for use, and when the trigger 106 is pulled, the feed pipe connected to the connector 105 is fed into the interior of the main gun body 101 until the multi-component sprays enter the two grouping fluid channels 107 respectively, and enter the interior of the mixing mechanism 108 again through the two grouping fluid channels 107, and the polyurethane is mixed after entering the interior of the mixing mechanism 108, and then sprayed out to the outside world again through the spray hole 109, so as to facilitate the spraying of the polyurethane fast-solidifying material through the spray gun body 100, and when cleaning, the air intake is cleaned through the air quick-connect hose 102;

[0033] Then, when the spray gun body 100 connects the connector 105 to the feed pipe before use, the feed pipe is passed through the inside of the mounting ring 1051 and fits against the inner surface of the fixed clamping plate 1057, and the hand-held knob 1055 drives the threaded rod 1056 to move. When the threaded rod 1056 moves, it drives the movable clamping plate 1054 to move and clamp and fix on the surface of the feed pipe, so that the feed pipe and the connector 105 are installed and fixed again, and the tight fixation is strengthened during the rotation reinforcement, and the feed pipe will not be pressed and blocked to affect the discharge, so that the spray gun body 100 is subjected to the gravity of the feed pipe during spraying and is strengthened during continuous movement, and is not easy to cause shaking, instability or falling off, thereby improving the strengthening and fixation of the connection between the feed pipe and the connector 105 when the spray gun body 100 is spraying the polyurethane rapid solidification material;

[0034] Finally, before using the spray gun body 100, close the external threaded ring 1043 on the end of the main gun body 101 and rotate the fixing screw 1044 to fix it, and then rotate the internal threaded ring 1042 on the outer surface of the external threaded ring 1043 to fix the protective cover 1041 on the end of the main gun body 101 at the outer surface of the nozzle 104. After fixed installation, when the spray gun body 100 is vigorously spraying polyurethane fast-setting material, the splashing polyurethane fast-setting material is isolated and protected by the protective cover 1041, which is not easy to cause splashing and adhesion of materials on the hands and the rear surface of the spray gun body 100, which is convenient for protection during operation and improves the isolation and protection effect of the spray gun body 100 when spraying polyurethane fast-setting material.
