Description

Technical Field

[0001] This utility model relates to the field of pipe processing, specifically to a painting device for metal pipes. Background Technology

[0002] Metal pipes, as a common type of metal profile, are an excellent choice for both support and transportation. Their unique rigidity and resistance to cold and heat allow them to be well-suited to various working environments and to accommodate fluids of various properties. However, due to their metallic characteristics, metal pipes are prone to rust and corrosion. Once metal pipes rust or corrode, there are significant hidden dangers. Therefore, it is necessary to paint the pipes, which can effectively protect them and enhance their appearance.

[0003] The existing painting methods for metal pipes are mostly direct spraying, which involves aiming the spray nozzle at the pipe and applying the paint directly to the surface of the pipe. Then, the paint on the surface of the pipe is heat-cured to complete the painting work of the metal pipe.

[0004] However, in the actual painting process, temperature has a significant impact on the painting effect. When the temperature is too low, the drying time of the paint will be longer, the coating will dry slowly, the viscosity of the paint will increase, and the fluidity will be reduced. This may result in brush marks, orange peel, and other problems on the coating surface. At the same time, in a low-temperature environment, the adhesion of the paint will decrease, which may cause the coating to peel off, flake, or crack. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a painting device for metal pipes to solve the technical problem that low temperature will affect the painting effect of metal pipes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a painting device for metal pipes, comprising a base, with movable seats and fixed seats arranged on both sides of the top of the base, a mounting seat slidably arranged on the top of the base, a driving mechanism mounted on the top of the mounting seat, multiple spray nozzles arranged on the top of the mounting seat, and a dryer mounted on the top of the mounting seat on one side of the spray nozzles. Rotary discs are rotatably connected to the opposite surfaces of the movable seats and fixed seats, and multiple positioning blocks are threadedly connected to one side of each rotating disc. The rotating discs are hollow, and the rotating discs of the movable seats are connected to the dryer via a pipe.

[0007] The present invention is further configured such that the air outlet of the dryer is provided with a vertical air outlet and an inclined air outlet.

[0008] The present invention is further configured such that the driving mechanism includes a motor, a gear and a rack, the motor is mounted on the top of the mounting base, the output end of the motor is connected to the gear, and the mounting base is provided with a rack inside, and the gear and the rack mesh with each other.

[0009] The present invention is further configured such that the positioning blocks are assembled with each other through threaded portions, and the assembled positioning blocks are conical.

[0010] The present invention is further provided that the outer wall of the positioning block is provided with a rubber pad.

[0011] The present invention is further provided that a rotational sealing structure is provided between the rotating disk and the movable seat and the fixed seat.

[0012] The present invention is further configured such that the top of the fixed base is provided with an air outlet, and the air outlet is connected to the rotating disk.

[0013] In summary, the present invention has the following beneficial effects: The pipe is placed between the movable seat and the fixed seat, and the metal pipe is sprayed with paint through the spray nozzle. During the spraying process, the paint is dried by the dryer. The hot air of the dryer can also be introduced into the rotating plate through the pipe and injected into the pipe through the positioning block to preheat the inner wall of the pipe, effectively increasing the temperature of the inner and outer surfaces of the pipe. When the paint is sprayed and adheres to the surface of the pipe, it can effectively improve the drying speed and the coating quality of the paint. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] A painting device for metal pipes, such as Figure 1-3 As shown, the device includes a base 1, with a movable seat 2 and a fixed seat 3 on both sides of the top of the base 1. A rotating disk 10 is rotatably connected to the opposite surfaces of the movable seat 2 and the fixed seat 3. Multiple positioning blocks 13 are threadedly connected to one side of each rotating disk 10. The positioning blocks 13 are assembled with each other through threaded portions 14, and the assembled positioning blocks 13 are conical. The positioning blocks 13 constitute a positioning fixture for the pipe. The movable seat 2 is slidably installed on the top of the base 1. The pipe is placed between the movable seat 2 and the fixed seat 3. The movement of the movable seat 2 is controlled to clamp the pipe. The specific sliding structure of the movable seat 2 is not shown in the figure. It is a common screw linear guide mechanism. Those skilled in the art can choose a suitable structure for use.

[0020] A mounting base 4 is slidably mounted on the top of the base 1. A drive mechanism 5 is mounted on the top of the mounting base 4. Multiple paint spray heads 6 are mounted on the top of the mounting base 4. A dryer 7 is mounted on one side of the paint spray head 6 on the top of the mounting base 4. The paint spray head 6 is connected to an external paint supply device. The drive mechanism 5 includes a motor, gears, and racks. The motor is mounted on the top of the mounting base 4. The output end of the motor is connected to the gears. A rack is installed inside the mounting base 4, and the gears and racks mesh with each other. The rotating disk 10 is a hollow structure, and the rotating disk 10 of the movable base 2 is connected to the dryer 7 through a pipe. After the pipe is placed, the motor of the drive mechanism 5 is started. The motor drives the gears and racks to mesh and transmit, controlling the mounting base 4 to move along the top of the base 1 and turning on the dryer 7. Part of the hot air from the dryer 7 is blown out to preheat the surface of the pipe, and the other part of the hot air enters the rotating disk 10 through the pipe.

[0021] The positioning block 13 has a hollow structure inside and is connected to the rotating disk 10. After hot air enters the rotating disk 10, it is sprayed out from the positioning block 13. Since the positioning block 13 is inserted into the pipe as a tooling fixture, the hot air sprayed out from the positioning block 13 will preheat the inner wall of the pipe. Combined with the external preheating of the dryer 7, the pipe can be effectively heated to reach the appropriate painting temperature.

[0022] Furthermore, the air outlet of the dryer 7 is equipped with a vertical air outlet 8 and an inclined air outlet 9. The vertical air outlet 8 and the inclined air outlet 9 can improve the air outlet position of the dryer 7, so that it can heat the outer wall of the pipe comprehensively.

[0023] Meanwhile, after the pipe is preheated, it needs to be painted. The external paint supply equipment provides paint to the spray head 6. The paint is sprayed out from the spray head 6. With the movement of the mounting base 4, the rotating motor 12 installed on the outer wall of the fixed base 3 controls the rotation of the rotating disk 10 and the pipe, so that the paint can be completely sprayed onto the surface of the pipe. The mechanism for controlling the pipe is a common motor rotation mechanism, so it is not described in detail. The hot air sprayed from the dryer 7 can increase the drying speed of the paint during the painting process.

[0024] Furthermore, the positioning blocks 13 are assembled with each other through the threaded part 14, and the assembled positioning blocks 13 are conical, so they can be adapted to metal pipes of different diameters. The outer wall of the positioning block 13 is provided with a rubber pad 11. After being inserted into both ends of the pipe, the rubber pad 11 can effectively improve the sealing effect and prevent hot air from flowing out, thus affecting the preheating effect.

[0025] A rotational sealing structure is provided between the rotating disk 10, the movable seat 2, and the fixed seat 3. The rotational sealing structure allows hot air to be transferred smoothly without affecting the rotation of the rotating disk 10.

[0026] The top of the fixed base 3 is provided with an air outlet, which is connected to the rotating disk 10. The air outlet is connected to the outside through a pipe. The hot air blown out by the dryer 7 is discharged from the air outlet, completing a hot air circulation process.

[0027] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
