Description

Technical Field

[0001] This utility model relates to the field of metal product spraying technology, specifically to a surface spraying device for metal products. Background Technology

[0002] Spray paint is a common decorative and protective material. It can form a hard, smooth, and beautiful coating on various surfaces. Spray paint can be made of artificial paints such as nitrocellulose, resin, pigments, and solvents. It can also be applied to metal using the principle of compressed air. Because metal products are relatively heavy, when spraying paint around the surface of a metal product, the paint is easily thrown out by centrifugal force, and the paint is easily unevenly distributed on the surface of the metal product, resulting in an uneven surface.

[0003] The existing technology has the following problems:

[0004] 1. Existing surface spraying equipment for metal products has the problem of poor spraying effect when spraying paint on the surface of metal pipes. It is not only difficult to effectively and evenly spray paint on the surface of metal pipes, but also easy to create spraying blind spots at the clamping points of the pipes.

[0005] 2. In the use of existing surface spraying equipment for metal products, when applying paint to the metal pipe clamping device, the large weight of the pipe itself makes moving the pipe quite cumbersome. Utility Model Content

[0006] This invention provides a surface coating device for metal products to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A surface coating device for metal products includes a coating body and a paint gun. A fixed chamber is fixedly connected to one end of the top of the coating body, and a toothed ring is rotatably connected to the inner wall of the fixed chamber. A fixed ring is fixedly connected to the inner wall of the toothed ring.

[0009] The inner wall of the spraying body is rotatably connected to both ends of a traction rod, and both ends of the outer wall of the traction rod are provided with a moving platform. The top of the moving platform is provided with a fixing component, and the bottom of the moving platform is provided with an electric roller. The bottom of the electric roller is slidably connected to the bottom of the inner wall of the spraying body.

[0010] A further improvement of the present invention is that the fixing component includes an arc-shaped block slidably connected to the top of one side of the inner cavity of the moving platform, and a support block is fixedly connected to one side of the outer wall of the arc-shaped block. A closing block is rotatably connected to the top of the support block, and one end of the closing block is engaged with one side of the outer wall of the support block.

[0011] A further improvement of the present invention is that: a plurality of slots are provided on one side of the inner wall of the fixing ring, and the inner wall of the slots is engaged with the outer wall of the closing block and the support block.

[0012] A further improvement of this utility model is that: the inner walls of the closing block and the supporting block are both fixedly connected to several fixed boxes, and the inner walls of the fixed boxes are fixedly connected to electric telescopic rods, while the output end of the electric telescopic rods is rotatably connected to a contact wheel.

[0013] A further improvement of the present invention is that: a drive motor is fixedly connected to one end of the top of the spraying body near the fixed chamber, and a drive gear is fixedly connected to the output end of the drive motor, and the top of the drive gear meshes with the outer wall of the gear ring.

[0014] A further improvement of this utility model is that: a support gear is rotatably connected to the top end of the spraying body away from the transmission motor, and the top of the support gear meshes with the outer wall of the gear ring.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a surface spraying device for metal products. By performing a secondary coating on the parts of the metal pipe surface that are not fully coated with paint, and by fixing the metal pipe by clamping at both ends, the device can spray the pipe surface over the largest area at once. After the paint dries, the position of the moving table is adjusted to coat the uncoated areas. This further solves the problem that traditional surface spraying devices for metal products are difficult to use effectively and evenly when spraying paint on the surface of metal pipes, and are prone to creating spraying blind spots at the clamping points of the pipes, resulting in poor spraying effect.

[0017] 2. This utility model provides a surface spraying device for metal products. By pushing one end of a metal tube, the outer wall of the metal tube rolls under the action of a contact wheel that clamps it, and the inner wall of the metal tube can be easily moved, exposing the unpainted areas on the surface of the metal tube. This makes it easier for operators to touch up the unpainted areas, further solving the problem that in the use of traditional surface spraying devices for metal products, the movement of the tube is cumbersome due to its large weight when touching up the metal tube clamping device.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-5 As shown, this utility model provides a surface spraying device for metal products, including a spraying body 1 and a spray gun 17. A fixed chamber 2 is fixedly connected to one end of the top of the spraying body 1, and a toothed ring 3 is rotatably connected to the inner wall of the fixed chamber 2. A fixed ring 4 is fixedly connected to the inner wall of the toothed ring 3. A traction rod 5 is rotatably connected to both ends of the inner wall of the spraying body 1, and a moving platform 6 is provided at both ends of the outer wall of the traction rod 5. The protrusion of the moving platform 6 is embedded in the closed threaded groove of the traction rod 5. The traction rod 5 rotates to drive the moving platform 6 to reciprocate. The bottom of the moving platform 6 is slidably connected to the top of the spraying body 1. A fixing component is provided on the top of the moving platform 6. The fixing component includes an arc-shaped block 7 slidably connected to the top of one side of the inner cavity of the moving platform 6, and a support block 8 is fixedly connected to one side of the outer wall of the arc-shaped block 7. A closing block 9 is rotatably connected to the top of the support block 8, and one end of the closing block 9 is engaged with one side of the outer wall of the support block 8.

[0026] During operation, traction rods 5 are installed at both ends of the inner wall of the spraying body 1, and moving platforms 6 are installed at both ends of the outer wall of the traction rods 5. Since the bottom of the moving platform 6 is equipped with electric rollers (electric rollers are existing technology), when the forklift lifts the metal pipe, the electric rollers at the bottom of the moving platform 6 are activated, so that the moving platform 6 moves to the side of the top of the spraying body 1 away from the fixed chamber 2 under the guidance of the traction rods 5, leaving a gap between the two moving platforms 6, so that the forklift's insert plate is between the two moving platforms 6. An arc-shaped block 7 is installed at the top of one side of the inner cavity of the moving platform 6, and a support block 8 is installed on one side of the outer wall of the arc-shaped block 7. The metal pipe placed on the surface of the insert plate is lifted by the fixing box 11 and the contact wheel 13 installed on the inner wall of the support block 8. Then, the closing block 9 installed at the top of the support block 8 is rotated so that one end of the closing block 9 is inserted into one side of the outer wall of the support block 8, and the metal pipe is wrapped. Then, the electric rollers are started again, and the moving platform 6 and the metal pipe are moved towards the fixed chamber 2. Since the inner wall of the fixed chamber 2 is provided with a toothed ring 3 and the inner wall of the toothed ring 3 is provided with a fixing ring 4, when the moving platform 6 near the fixing ring 4 first comes into contact with the outer wall of the fixed chamber 2 and the support block 8 and the closing block 9 are inserted into the fixing ring 4, the transmission motor 14 provided at the top of the spraying body 1 near the fixed chamber 2 is started, so that the transmission motor 14 drives the transmission gear 15 provided at the output end, and drives the toothed ring 3 and the fixing ring 4 to rotate. Thus, the slot 10 provided in the inner wall of the fixing ring 4 pushes the support block 8 and the closing block 9. Under the restriction of the arc block 7, they rotate 150 degrees clockwise and counterclockwise with the metal pipe as the center. At this time, the workers use the external spray gun 17 to spray the paint on the surface of the metal pipe, thus completing the spraying of the surface of the metal pipe.

[0027] It should be further explained that, since the metal pipe is constantly in a state of continuous rotation at a relatively slow speed, when the paint gun 17 sprays paint onto the surface of the metal pipe, on the one hand, the inertia generated during the rotation of the metal pipe causes excess paint on its surface to concentrate at the bottom of the metal pipe and drip down along the bottom. On the other hand, as the paint continuously moves towards the bottom of the metal pipe, the parts of the metal pipe surface that are not completely coated with paint can be coated a second time. Moreover, by using the clamping method to fix the metal pipe at both ends, the surface of the pipe can be sprayed over the largest possible area at once. After the paint dries, the position of the moving table 6 can be adjusted to coat the un-sprayed areas. This further solves the problem that, in the use of traditional surface spraying devices for metal products, it is not only difficult to effectively and evenly spray paint onto the surface of the metal pipe, but also easy to create spraying blind spots at the clamping points of the pipe, resulting in poor spraying effect.

[0028] A plurality of slots 10 are provided on one side of the inner wall of the fixing ring 4, and the inner wall of the slots 10 is engaged with the outer wall of the closing block 9 and the support block 8. A plurality of fixing boxes 11 are fixedly connected to the inner walls of the closing block 9 and the support block 8, and an electric telescopic rod 12 is fixedly connected to the inner wall of the fixing box 11. The output end of the electric telescopic rod 12 is rotatably connected to a contact wheel 13. A drive motor 14 is fixedly connected to the top end of the spraying body 1 near the fixing chamber 2, and a drive gear 15 is fixedly connected to the output end of the drive motor 14. The top of the drive gear 15 meshes with the outer wall of the gear ring 3. A support gear 16 is rotatably connected to the top end of the spraying body 1 away from the drive motor 14, and the top of the support gear 16 meshes with the outer wall of the gear ring 3.

[0029] During operation, several slots 10 are provided on one side of the inner wall of the fixed ring 4. When the electric roller drives the moving platform 6 close to the fixed chamber 2, the closing block 9 and one side of the outer wall of the support block 8 are embedded in the slots 10. Several fixing boxes 11 are provided on the inner walls of the closing block 9 and the support block 8. The electric telescopic rod 12 provided on the inner wall of the fixing box 11 is activated, causing the contact wheel 13 provided at the output end of the electric telescopic rod 12 to move towards the center between the support block 8 and the closing block 9. The surface of the contact wheel 13 pushes the metal tube to the center, thereby moving the metal tube to the center. The tubing is then fixed in place. At this point, the drive motor 14, located at the top of the spraying body 1 near the fixing chamber 2, is activated. The drive motor 14 drives the drive gear 15 at its output end, causing the gear ring 3 to rotate within the fixing chamber 2. Simultaneously, a support gear 16, located at the top of the spraying body 1 away from the drive motor 14, works in conjunction with the drive gear 15 to support both ends of the bottom of the gear ring 3. This ensures greater stability when the gear ring 3 rotates, driving the fixing ring 4, support block 8, closing block 9, and the metal tubing.

[0030] It should be further explained that after the surface of the metal pipe is painted and the paint on the surface of the metal pipe dries, pushing one end of the metal pipe causes the contact wheel 13 clamping the outer wall of the metal pipe to roll under the action of lateral thrust, and the metal pipe clamped by the inner wall can be easily moved, exposing the unpainted areas on the surface of the metal pipe due to clamping. This makes it easier for operators to touch up the unpainted areas, further solving the problem that when using traditional surface spraying devices for metal products, the movement of the pipe is cumbersome due to the large weight of the pipe itself when touching up the paint on the clamping device.

[0031] The working principle of the surface coating device for metal products will be explained in detail below.

[0032] like Figures 1-5As shown, by setting traction rods 5 at both ends of the inner wall of the spraying body 1, and setting moving platforms 6 at both ends of the outer wall of the traction rods 5, and since the bottom of the moving platform 6 is equipped with electric rollers (the electric rollers here are existing technology), when the forklift lifts the metal pipe, the electric rollers at the bottom of the moving platform 6 are activated, so that the moving platform 6 moves to the side of the top of the spraying body 1 away from the fixed chamber 2 under the guidance of the traction rods 5, and a gap is left between the two moving platforms 6 so that the forklift's insert plate is between the two moving platforms 6. By setting an arc-shaped block 7 at the top of one side of the inner cavity of the moving platform 6, and setting a support block 8 on one side of the outer wall of the arc-shaped block 7, the metal pipe placed on the surface of the insert plate is lifted by using the fixing box 11 and contact wheel 13 set on the inner wall of the support block 8. Then, the closing block 9 set on the top of the support block 8 is rotated so that one end of the closing block 9 is inserted into one side of the outer wall of the support block 8 and wraps the metal pipe. Then, the electric rollers are activated again, and the moving platform 6 and the metal pipe are moved towards the fixed chamber 2. Since the inner wall of the fixed chamber 2 is equipped with The device has a gear ring 3, and a fixing ring 4 is provided on the inner wall of the gear ring 3. When the moving platform 6 near the fixing ring 4 first comes into contact with the outer wall of the fixing chamber 2, and the support block 8 and the closing block 9 are inserted into the fixing ring 4, the transmission motor 14 provided at the top of the spraying body 1 near the fixing chamber 2 is started. The transmission motor 14 drives the transmission gear 15 provided at the output end, which drives the gear ring 3 and the fixing ring 4 to rotate. The slot 10 provided on the inner wall of the fixing ring 4 pushes the support block 8 and the closing block 9. Under the restriction of the arc block 7, they rotate 150 degrees clockwise and counterclockwise around the metal pipe. At this time, the worker uses the external spray gun 17 to spray paint on the surface of the metal pipe, thereby completing the spraying of the metal pipe surface. This further solves the problem that in the process of using traditional surface spraying devices for metal products, it is not only difficult to effectively and evenly spray paint on the surface of the metal pipe, but also easy to create spraying blind spots at the clamping point of the pipe, resulting in poor spraying effect.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
