Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, and in particular to a building coating spray gun. Background Technology

[0002] A spray gun is a device that uses the rapid release of liquid or compressed air as its power source. Spray guns are divided into two types: standard pressure and pressurized. There are also pressure spray guns, cartridge spray guns, and automatic recovery spray guns. In various industries, spray guns can be used directly with paint (simple spray guns) or installed in automated equipment such as automatic glue spraying machines, automatic adhesive applicators, automatic paint spraying machines, and coating machines. Paint, which adheres well to the substrate material and forms a complete and tough protective film when applied to the surface of an object, is called architectural coating. Spray guns are required when spraying architectural coatings.

[0003] A spray gun generally consists of a spray gun body and a storage tank. One type of spray gun, in which the storage tank is installed on the upper part of the spray gun body, feeds the paint into the interior of the spray gun body by gravity. This feeding method may cause some paint to adhere to the inner wall of the storage tank, wasting paint and making subsequent cleaning of the storage tank more troublesome. Therefore, a new type of architectural paint spray gun is needed to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions in this specification and facilitating understanding by those skilled in the art. The fact that these solutions have been described in the background section of this specification should not be construed as meaning that the aforementioned technical solutions are known to those skilled in the art.

[0009] Preferably, in any of the above embodiments, a guide plate is fixedly connected to the outer surface of the end cap, a guide rod passes through the guide plate, and the guide rod is slidably connected to the guide plate. The guide plate and the guide rod guide the movable ring seat, so that the movable ring seat can only move in a straight line in the vertical direction.

[0010] Preferably, in any of the above solutions, the inner diameter of the movable ring seat is equal to the outer diameter of the storage tank, and the movable ring seat is slidably connected to the storage tank, so that the movable ring seat can move smoothly.

[0011] Preferably, in any of the above embodiments, the extrusion rod passes through the end cap and extends into the interior of the storage tank. The extrusion rod is slidably connected to the end cap, and the scraper is slidably connected to the storage tank. The diameter of the scraper is equal to the inner diameter of the storage tank. The scraper is located below the connecting ring seat, so that the extrusion rod can smoothly drive the scraper to move, allowing the scraper to scrape off the coating adhering to the inner wall of the storage tank.

[0012] Preferably, in any of the above embodiments, the bottom end of the guide funnel corresponds to the position of the discharge pipe, and the guide funnel guides the paint, allowing the paint to flow quickly into the interior of the discharge pipe.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Through the coordinated arrangement of the lead screw, moving block, moving ring seat, connecting block, guide rod, push plate, extrusion rod, scraper, and guide funnel, the scraper can move downwards to scrape off the paint adhering to the inner wall of the storage tank. The scraped paint is then guided into the interior of the spray gun body by the guide funnel and discharge pipe for spraying, thus avoiding paint adhesion to the inner wall of the storage tank, saving paint. Furthermore, the coordinated arrangement with the connecting ring seat, end cap, and storage tank facilitates the installation and removal of the end cap, making it easy to remove the scraper from the inside of the storage tank, thus simplifying the cleaning of the storage tank.

[0015] 2. The sweat-absorbing cotton can absorb the sweat produced by the operator's hands during work, preventing the spray gun body from slipping due to sweat. The anti-slip texture can increase the friction between the operator's hand and the spray gun body. By wrapping the wristband around the operator's wrist, the operator can hold the spray gun body more stably, thereby greatly preventing the spray gun body from falling from the operator's hand during the spraying process and ensuring the smooth progress of the spraying work.

A mounting block 6 is fixedly connected to the outer surface of the end cap 5. A lead screw 7 is rotatably connected to one side of the mounting block 6 via a bearing. A knob is fixedly connected to the top of the lead screw 7. A moving block 8 is threadedly connected to the outer surface of the lead screw 7. A moving ring seat 9 is fixedly connected to one side of the moving block 8. A connecting block 10 is fixedly connected to the surface. A guide rod 11 is fixedly connected to one side of the connecting block 10. A push plate 12 is fixedly connected to the top of the guide rod 11. An extrusion rod 13 is fixedly connected to one side of the push plate 12. A scraper 14 is fixedly connected to the bottom of the extrusion rod 13. A guide funnel 15 is fixedly connected to the bottom of the storage tank 3. When spraying is performed, the amount of paint inside the storage tank 3 gradually decreases. By rotating the knob connected to the lead screw 7, the lead screw 7 is rotated. At this time, the moving block 8 drives the moving ring seat 9 to move downward. As the moving ring seat 9 moves, the connecting block 10 drives the guide rod 11 to move downward, thereby causing the push plate 12 to drive the extrusion rod 13 to move downward. At this time, the scraper 14 moves downward and scrapes the paint adhering to the inner wall of the storage tank 3.

[0023] As an optional technical solution of this utility model, a mounting groove is provided on one side of the spray gun body 1, and a sweat-absorbing cotton 16 is fixedly connected to the inner wall of the mounting groove. An anti-slip texture 17 is provided on one side of the spray gun body 1, and a wrist strap 18 is fixedly connected to one side of the spray gun body 1, which can greatly prevent the spray gun body 1 from falling from the operator's hand during the spraying process.

[0024] As an optional technical solution of this utility model, a guide plate 19 is fixedly connected to the outer surface of the end cover 5, and a guide rod 11 passes through the guide plate 19. The guide rod 11 is slidably connected to the guide plate 19. The guide plate 19 and the guide rod 11 guide the moving ring seat 9 so that the moving ring seat 9 can only move in a straight line in the vertical direction.

[0025] As an optional technical solution of this utility model, the inner diameter of the movable ring seat 9 is equal to the outer diameter of the storage tank 3, and the movable ring seat 9 is slidably connected to the storage tank 3, so that the movable ring seat 9 can move smoothly.

[0026] As an optional technical solution of this utility model, the extrusion rod 13 passes through the end cover 5 and extends into the interior of the storage tank 3. The extrusion rod 13 is slidably connected to the end cover 5, and the scraper 14 is slidably connected to the storage tank 3. The diameter of the scraper 14 is equal to the inner diameter of the storage tank 3. The scraper 14 is located below the connecting ring seat 4, so that the extrusion rod 13 can smoothly drive the scraper 14 to move, so that the scraper 14 scrapes off the coating adhering to the inner wall of the storage tank 3.

[0027] As an optional technical solution of this utility model, the bottom end of the guide funnel 15 corresponds to the position of the discharge pipe 2. The guide funnel 15 guides the paint, enabling the paint to flow quickly into the interior of the discharge pipe 2.

[0028] A type of architectural paint spray gun, the working principle of which is as follows:

[0029] During the spraying process, the amount of paint inside the storage tank 3 gradually decreases. Rotating the knob connected to the lead screw 7 causes the lead screw 7 to rotate. At this time, the moving block 8 drives the moving ring seat 9 to move downward. As the moving ring seat 9 moves, the connecting block 10 drives the guide rod 11 to move downward, thereby causing the push plate 12 to drive the extrusion rod 13 to move downward. At this time, the scraper 14 moves downward and scrapes the paint adhering to the inner wall of the storage tank 3, causing the paint adhering to the inner wall of the storage tank 3 to move downward, thus preventing the paint from adhering to the inner wall of the storage tank 3.

[0030] In summary, this architectural paint spray gun, through the coordinated arrangement of the lead screw 7, moving block 8, moving ring seat 9, connecting block 10, guide rod 11, push plate 12, extrusion rod 13, scraper 14, and guide funnel 15, enables the scraper 14 to move downwards and scrape the paint adhering to the inner wall of the storage tank 3. The scraped paint, under the action of the guide funnel 15 and the discharge pipe 2, enters the interior of the spray gun body 1 for spraying, thus avoiding paint adhesion to the inner wall of the storage tank 3, saving paint. Furthermore, the coordinated arrangement with the connecting ring seat 4, end cap 5, and storage tank 3 facilitates the installation and removal of the end cap 5. This makes it easier to remove the scraper 14 from the inside of the storage tank 3, making the cleaning of the storage tank 3 simpler. The sweat-absorbing cotton 16 can absorb the sweat produced by the operator's hands during work, preventing the spray gun body 1 from slipping due to sweat. The anti-slip texture 17 can increase the friction between the operator's hands and the spray gun body 1. By wrapping the wrist strap 18 around the operator's wrist, the operator can hold the spray gun body 1 more stably, thus greatly preventing the spray gun body 1 from falling from the operator's hands during the spraying process and ensuring the smooth progress of the spraying work.
