Description

Technical Field

[0001] This application relates to the field of paint spraying, and more particularly to an acrylic resin paint film-forming spraying apparatus. Background Technology

[0002] Acrylic resin coatings are synthetic resin coatings with acrylic resin as the main film-forming substance. They are divided into two categories: thermoplastic and thermosetting. Thermoplastic acrylic paints rely on solvent evaporation for drying and are commonly used in construction, automotive, and other fields. Thermosetting acrylic paints cure through cross-linking of functional groups such as hydroxyl and carboxyl groups and are suitable for high-requirement applications such as aerospace and medical devices. Acrylic resin coatings are often applied using spray guns. A conventional spray gun is simply a tool for spraying paint for surface treatment of products and is a type of coating equipment. It works by atomizing paint into tiny droplets using compressed air, which are then sprayed onto the surface of the object under the influence of the airflow. It mainly consists of a spray cap, nozzle, needle valve, and gun body. An external air pressure device needs to be connected. When using a conventional spray gun, the user holds the spray gun body, which has a nozzle attached to one end. The top of the nozzle is connected to a storage tank. The paint to be sprayed is added to the storage tank, and one end of the spray gun body is connected to the air pressure device. The air pressure device pressurizes the paint and sprays it onto the surface of the object, thus completing the paint spraying process.

[0003] Regarding the aforementioned technologies, the inventors believe that when using conventional spray guns, the paint is often in a viscous state, which easily leads to paint sticking to the sides of the spray gun during actual use. This makes it difficult to use up all the paint, and if not cleaned in time, the paint can solidify in the storage tank, affecting the ease of use of the spray gun.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue of paint sticking to the walls of conventional spray guns during paint storage, this application provides an acrylic resin paint film-forming spraying device.

[0006] The acrylic resin coating film-forming spraying device provided in this application adopts the following technical solution: An acrylic resin coating film-forming spraying device includes a spray gun body and a pusher plate. A nozzle is fixedly installed at one end of the spray gun body, and a storage tank is connected to the top of the nozzle. A threaded rod is fixedly connected to one end of the pusher plate, and a control handle is fixedly installed at one end of the threaded rod. A connecting ring is threadedly connected to the surface of the threaded rod, and several mounting brackets are fixedly installed on the surface of the connecting ring. The surface of the pusher plate is slidably connected to the inner wall of the storage tank, and the dimensions of the pusher plate surface are adapted to the dimensions of the inner wall of the storage tank. The center of the pusher plate and the center of the threaded rod are on the same straight line.

[0007] Preferably, a plurality of the mounting brackets are arranged in a circular array with the center of the connecting ring as the axis, and a limiting bracket is rotatably mounted on the inner wall of the mounting bracket, the surface of the limiting bracket being engaged with the surface of the storage tank.

[0008] Preferably, a first spring is fixedly connected to one end of the limiting frame, and the end of the first spring away from the limiting frame is fixedly installed on the surface of the mounting frame.

[0009] Preferably, the surface of the pusher plate is fixedly connected to two auxiliary rings, which are rubber rings, and the surfaces of the auxiliary rings are slidably installed with the inner wall of the storage tank, and the dimensions of the auxiliary ring surfaces are interference-fitted with the dimensions of the inner wall of the storage tank.

[0010] Preferably, one end of the connecting ring is fixedly connected to a second spring, and the center of the second spring is on the same straight line as the center of the threaded rod.

[0011] Preferably, a bearing is fixedly installed at the end of the second spring away from the connecting ring, and one end of the bearing is rotatably connected to one end of the control handle.

[0012] Preferably, the surface of the limiting frame is fitted with a plurality of limiting frames, which are arranged in a circular array around the center of the storage tank. The dimensions of the inner wall of the limiting frame are adapted to the dimensions of the surface of the limiting frame, and one end of the limiting frame is fixedly installed on the surface of the storage tank.

[0013] In summary, this application includes the following beneficial technical effects: 1. By installing a push plate inside a storage tank, one end of the push plate is connected to a control handle via a threaded rod. The surface of the threaded rod is connected to the surface of the storage tank via a connecting ring and a mounting bracket, allowing the control handle to rotate the threaded rod within the connecting ring. This rotates the push plate within the storage tank, pushing the paint adhering to the tank walls. A limit bracket is rotatably connected to the inner wall of the mounting bracket, allowing the connection between the mounting bracket and the storage tank to be released by pulling one end of the limit bracket. This makes installation and disassembly of the storage tank and mounting bracket more convenient. A first spring is installed at one end of the limit bracket to keep it engaged with the surface of the storage tank. Two rubber auxiliary rings are installed on the surface of the push plate to improve the seal between the push plate and the storage tank. Compared to existing technologies, this significantly improves the ease of use of the paint spray gun. 2. A second spring can also be installed at one end of the connecting ring to keep the pusher moving downwards, preventing the pusher from shifting due to loosening of the threaded rod. One end of the second spring is rotatably connected to the surface of the control handle with the aid of a bearing to reduce the friction between the second spring and the control handle. One end of the limit frame is fixedly installed on the limit frame on the surface of the storage tank to limit the position of the limit frame, effectively improving the performance of the device.

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses an acrylic resin coating film-forming spraying apparatus, referring to... Figure 1 - Figure 2The spray gun includes a spray gun body 1. In use, the user holds the spray gun body 1, one end of which is fitted with a nozzle 2. The top of the nozzle 2 is connected to a storage tank 3. Paint to be sprayed is added to the storage tank 3, and one end of the spray gun body 1 is connected to an air pressure device. The air pressure device pressurizes the paint and sprays it onto the surface of the object to be coated, thus completing the paint spraying process. A push plate 4 is installed inside the storage tank 3. One end of the push plate 4 is fitted with a threaded rod 5, and one end of the threaded rod 5 is connected to a control handle 6. A connecting ring 7 is installed on the surface of the threaded rod 5. The surface of the connecting ring 7 is connected to the surface of the storage tank 3 via a mounting bracket 8. By using the control handle 6 to rotate the threaded rod 5 within the connecting ring 7, the push plate 4 at one end of the threaded rod 5 moves within the storage tank 3, pushing away any paint adhering to the walls of the storage tank 3. This effectively improves the convenience of using the paint spray gun and avoids the inconvenience caused by paint adhering to the walls.

[0018] Reference Figure 2 The inner wall of the mounting bracket 8 is rotatably connected to a limiting bracket 9. One end of the limiting bracket 9 is engaged with the surface of the storage tank 3. The limiting bracket 9 keeps the mounting bracket 8 engaged with the surface of the storage tank 3. Pulling one end of the limiting bracket 9 releases the connection between the mounting bracket 8 and the storage tank 3, making it more convenient to install and remove the storage tank 3 and the mounting bracket 8. One end of the limiting bracket 9 is equipped with a first spring 10, and one end of the first spring 10 is fixedly connected to the surface of the mounting bracket 8. The first spring 10 pushes one end of the limiting bracket 9, keeping one end of the limiting bracket 9 engaged with the surface of the storage tank 3. Two rubber auxiliary rings 11 are installed on the surface of the push plate 4. The surface of the auxiliary rings 11 is slidably connected to the inner wall of the storage tank 3. The auxiliary rings 11 improve the sealing between the push plate 4 and the storage tank 3, effectively improving the pushing effect of the push plate 4 on the coating in the storage tank 3.

[0019] Reference Figure 2 - Figure 4 A second spring 12 is installed at one end of the connecting ring 7. The second spring 12 pulls one end of the control handle 6, thereby pushing the pusher downward and preventing the threaded rod 5 from loosening and causing the push plate 4 to shift. A bearing 13 is installed at one end of the second spring 12. One end of the bearing 13 is rotatably connected to the surface of the control handle 6. The bearing 13 reduces the friction between the second spring 12 and the control handle 6, thereby preventing the second spring 12 from rotating when the spray gun body 1 rotates. One end of the limit frame 9 is engaged with a limit frame 14. One end of the limit frame 14 is fixedly installed on the surface of the storage tank 3. The limit frame 14 restricts the position of the limit frame 9, thereby improving the stability of the limit frame 9 after installation.

[0020] The implementation principle of the acrylic resin coating film-forming spraying device in this application embodiment is as follows: A pusher plate 4 is installed inside a storage tank 3. A threaded rod 5 is installed at one end of the pusher plate 4, and a control handle 6 is connected to the other end of the threaded rod 5. A connecting ring 7 is installed on the surface of the threaded rod 5. The surface of the connecting ring 7 is connected to the surface of the storage tank 3 via a mounting frame 8, so that the threaded rod 5 can be rotated within the connecting ring 7 by the control handle 6. This controls the pusher plate 4 at one end of the threaded rod 5 to move within the storage tank 3, pushing the coating adhering to the wall of the storage tank 3, thus avoiding the inconvenience caused by coating adhering to the wall. A limit frame 9 is rotatably connected to the inner wall of the mounting frame 8. One end of the limit frame 9 is engaged with the surface of the storage tank 3, so that the limit frame can be used to... 9. The mounting bracket 8 is held in place with the surface of the storage tank 3, and the connection between the mounting bracket 8 and the storage tank 3 can be released by pulling one end of the limiting bracket 9. This makes it more convenient to install and remove the storage tank 3 and the mounting bracket 8. One end of the limiting bracket 9 is equipped with a first spring 10, and one end of the first spring 10 is fixedly connected to the surface of the mounting bracket 8. This allows the first spring 10 to push one end of the limiting bracket 9, holding it in place with the surface of the storage tank 3. Two rubber auxiliary rings 11 are installed on the surface of the push plate 4. The surface of the auxiliary rings 11 is slidably connected to the inner wall of the storage tank 3. This allows the auxiliary rings 11 to improve the sealing between the push plate 4 and the storage tank 3, effectively improving the pushing effect of the push plate 4 on the coating inside the storage tank 3.

[0021] A second spring 12 can also be installed at one end of the connecting ring 7, so that the control handle 6 can be pulled by the second spring 12, thereby keeping the pusher moving downward and preventing the push plate 4 from shifting due to the loosening of the threaded rod 5. A bearing 13 is installed at one end of the second spring 12, and one end of the bearing 13 is rotatably connected to the surface of the control handle 6, so that the friction between the second spring 12 and the control handle 6 can be reduced by the bearing 13, thereby preventing the second spring 12 from rotating when the spray gun body 1 rotates. One end of the limit frame 9 is snapped into the limit frame 14, and one end of the limit frame 14 is fixedly installed on the surface of the storage tank 3, so that the position of the limit frame 9 can be limited by the limit frame 14, thereby improving the stability of the limit frame 9 after installation.

[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
