Description

Technical Field

[0001] This utility model relates to the field of steel pipe production, specifically a steel pipe painting device. Background Technology

[0002] Steel pipes are a common piping material, typically made of steel, used to transport liquids, gases, and solids. They are widely used in construction, engineering, manufacturing, and other fields. Steel pipes generally have good strength and corrosion resistance and can be custom-manufactured to meet specific needs.

[0003] After the steel pipe forming and cutting process is completed, surface treatment is required, such as coating, plating or spraying paint, to improve corrosion resistance and appearance. Spraying paint is a common processing method in steel pipe surface treatment. However, steel pipe spraying mainly relies on manual operation or simple mechanical devices. These methods have problems such as uneven spraying, low efficiency and environmental pollution. Summary of the Invention

[0004] (1) Technical problems solved

[0005] The technical problem this utility model aims to solve is that steel pipe painting currently mainly relies on manual operation or simple mechanical devices, which have problems such as uneven painting, low efficiency, and environmental pollution.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A steel pipe spray painting device includes a spray tank, chucks on both inner walls of the spray tank, a motor on the outer side of the spray tank, the motor shaft passing through the spray tank and fixedly connected to the chucks, a support frame above the spray tank, a ball screw in the middle of the support frame, a slide on the ball screw nut assembly, a spray head on the slide, a screw motor on one side of the support frame, a synchronous pulley on the screw motor shaft, a synchronous belt on the synchronous pulley, a second ball screw at the bottom of the spray tank, a second synchronous pulley at one end of the second ball screw, a negative pressure machine on the second ball screw nut assembly, and a negative pressure hood above the negative pressure machine.

[0009] Furthermore, the chuck is a three-jaw chuck, which includes a first chuck and a second chuck. The first chuck is connected to the motor shaft, and a bearing is provided in the inner wall of the paint spray tank. The second chuck is connected to the bearing in the paint spray tank.

[0010] Furthermore, the nozzle is a paint nozzle, and a paint supply tank is provided outside the paint spray tank. The nozzle and the paint supply tank are connected by an oil pipe.

[0011] Furthermore, one end of the synchronous belt is connected to the synchronous pulley, and the other end is connected to the second synchronous pulley. One end of the second ball screw passes through the paint spray tank and extends to the outside of the paint spray tank. A limiting baffle is provided at one end of the second ball screw.

[0012] Furthermore, a motor fixing plate is provided below the lead screw motor, and the motor fixing plate is fixedly connected to the support frame.

[0013] Furthermore, the paint spray tank has discharge ports on both sides.

[0014] (3) Beneficial effects

[0015] The beneficial effects of the utility model are:

[0016] The system employs automated rotary painting of steel pipes, with a paint tank providing protection. This improves efficiency while preventing excessive paint spillage into the air during the painting process. A synchronous belt drives the nozzles and negative pressure unit to operate in sync, ensuring that the negative pressure hood and nozzles remain in synchronized positions throughout the painting process. After the nozzles spray paint onto the steel pipe surface, excess paint is drawn towards the bottom of the paint tank and absorbed by the negative pressure hood, reducing pollution to both indoor and outdoor environments and preventing indoor workers from inhaling atomized paint.

[0022] Please see Figure 1-2 The steel pipe spraying device shown includes a spray tank 1, chucks 2 on both inner walls of the spray tank 1, a motor 3 on the outer side of the spray tank 1, the motor 3 shaft passing through the spray tank 1 and fixedly connected to the chucks 2, a support frame 4 above the spray tank 1, a ball screw 5 in the middle of the support frame 4, a slide 6 on the nut of the ball screw 5, a spray nozzle 7 on the slide 6, a screw motor 8 on one side of the support frame 4, a synchronous pulley 8a on the shaft of the screw motor 8, a synchronous belt 9 on the synchronous pulley 8a, a second ball screw 10 at the bottom of the spray tank 1, a second synchronous pulley 10a at one end of the second ball screw 10, a negative pressure machine 11 on the nut of the second ball screw 10, and a negative pressure cover 12 above the negative pressure machine 11.

[0023] Chuck 2 is a three-jaw chuck, which includes a first chuck 2a and a second chuck 2b. The first chuck 2a is connected to the shaft of the motor 3. A bearing is provided in the inner wall of the paint tank 1. The second chuck 2b is connected to the bearing in the paint tank 1. The shaft of the motor 3 provides rotational power to the chuck 2. When the steel pipe needs to be painted, the steel pipe is put in from the discharge port 1a. Then, both ends of the steel pipe are put into the first chuck 2a and the second chuck 2b. Then, the chuck is adjusted to tighten and clamp the two ends of the steel pipe. The first chuck 2a is rotated by the motor 3, while one end of the second chuck is connected to the bearing for auxiliary rotation. When the motor 3 starts, the steel pipe is clamped and rotated under the drive of the chuck 2 to make its surface painted evenly.

[0024] The nozzle 7 is a paint nozzle. The paint tank 1 is equipped with a paint supply tank. The nozzle 7 is connected to the paint supply tank through an oil pipe. The connection between the paint supply tank, the oil pipe and the nozzle 7 is a common method and device for connecting paint nozzles. It will not be described in detail here, as it is existing technology. Paint is placed in the paint supply tank. Paint is supplied to the nozzle 7 through the oil pipe and sprayed onto the surface of the steel pipe through the nozzle 7.

[0025] One end of the synchronous belt 9 is connected to the synchronous pulley 8a, and the other end is connected to the second synchronous pulley 10a. One end of the second ball screw 10 passes through the paint tank 1 and extends to the outside of the paint tank 1. A limit stop 10b is provided at one end of the second ball screw 10. The function of the synchronous belt 9 is to connect the ball screw 5 and the second ball screw 10. The synchronous belt 9 is connected by the synchronous pulley 8a and the second synchronous pulley 10a. The synchronous pulley 8a and the second synchronous pulley 10a are respectively fixedly sleeved on the two ends of the ball screw 5 and the second ball screw 10. The ball screw 5 is rotated by the drive of the screw motor 8, converting the rotation into a linear motion. The linear motion drives the slide table 6 to reciprocate the spray nozzle 7. Simultaneously, the synchronous belt 9 drives the second ball screw 10 to move synchronously, causing the negative pressure unit 11 on the second ball screw 10 to move synchronously. This ensures that the negative pressure unit 11 is always below the nozzle 7. When the paint sprayed from the nozzle 7 is dispersed in a mist, the negative pressure unit 11 provides negative pressure to absorb it through the negative pressure cover 12. At the same time, the negative pressure unit 11 can be connected to an external air duct to concentrate or discharge the collected mist. The negative pressure unit 11 is fixed on the nut assembly of the second ball screw 10 and reciprocates through the nut assembly.

[0026] A motor fixing plate 8b is provided below the lead screw motor 8. The motor fixing plate 8b is fixedly connected to the support frame 4. A hollow groove 8c is opened on the motor fixing plate 8b. The synchronous belt 9 is connected to the second synchronous pulley 10a through the hollow groove 8c. The motor fixing plate 8b is used to fix the lead screw motor 8 on it, and the synchronous belt 9 is allowed to pass through the hollow groove 8c to connect with the second synchronous pulley 10a.

[0027] The paint spray tank 1 has discharge ports 1a on both sides. The discharge ports 1a are used to facilitate the entry of staff, daily maintenance, and placement and removal of steel pipes.

[0028] The specific working principle is as follows: the worker puts the steel pipe into the paint spray tank 1 through the discharge port 1a, clamps the two ends of the steel pipe with the chuck 2, then the motor 3 starts to drive the steel pipe to rotate, while the lead screw motor 8 drives the ball screw 5 and the second ball screw 10 to work, so that the spray head 7 reciprocates to spray paint, and the negative pressure hood 12 collects the emitted gaseous paint mist to prevent environmental pollution.
