Description

Technical Field

[0001] This utility model belongs to the technical field of pipe fitting rotating equipment, specifically relating to an automatic rotating equipment for the production of anti-corrosion pipe fittings. Background Technology

[0002] Currently, the base materials for anti-corrosion steel pipes include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. Three-layer anti-corrosion coatings, with their excellent corrosion resistance, water vapor penetration resistance, and mechanical properties, are widely used in the oil pipeline industry. The anti-corrosion layer is crucial to the lifespan of buried pipelines. Pipes of the same material can vary drastically; some can remain uncorroded underground for decades, while others leak within years. This difference stems from the different external anti-corrosion layers they employ.

[0003] During the production process, rotating equipment is needed to rotate the pipe fittings to spray the anti-corrosion layer. However, since traditional rotating equipment requires clamping and fixing the pipe fittings, the clamped parts of the pipe fittings cannot be sprayed during the spraying process due to the influence of the clamps. Often, it is necessary to spray both sides of the pipe fittings separately, which leads to low efficiency in spraying the pipe fittings. Furthermore, the secondary spraying of the pipe fittings in the center position results in different thicknesses of the anti-corrosion coating. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic rotating equipment for the production of anti-corrosion pipe fittings. This automatic rotating equipment aims to solve the technical problems of existing technologies, where traditional rotating equipment requires clamping and fixing the pipe fittings. During the spraying process, the clamped parts of the pipe fittings are affected by the clamps and cannot be sprayed, often requiring spraying on both sides of the pipe fittings separately. This results in low efficiency in the spraying of pipe fittings, and the secondary spraying of the pipe fittings in the center position leads to different thicknesses of the anti-corrosion coating.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides an automatic rotating device for producing anti-corrosion pipe fittings. The automatic rotating device for producing anti-corrosion pipe fittings includes a support box and drive rollers symmetrically arranged at the top of the support box. The top ends of the two drive rollers are clamped to the pipe fitting body. Slide grooves are opened on both sides of the top surface of the support box. Double threaded screws are rotatably installed in the two slide grooves. The two ends of the two double threaded screws with opposite thread directions are threaded with sliding frames connected to the drive rollers. Coating cotton is rotatably arranged in the support box to contact the outer wall of the pipe fitting body.

[0008] When using this technical solution, sliding frames are fixed in adjustable grooves on both sides of the top surface of the support box. The drive roller between the two sliding frames on the same side supports the pipe body, and the baffles at both ends of the drive rollers position the pipe body to prevent it from slipping between the two drive rollers. The first motor drives the drive roller to rotate, causing the pipe body to rotate. During the rotation, the paint cotton comes into contact with the pipe body, facilitating spraying of the rotating pipe body and improving the spraying effect. A double-threaded screw is embedded in the groove. When the second motor rotates, the double-threaded screw drives the sliding frame to move in the groove. During the movement of the sliding frame, the distance between the two baffles is adjusted, and the pipe body is tightly connected to the paint cotton during the adjustment process. This solution is suitable for the rotational spraying of pipe bodies of different sizes.

[0009] Preferably, both ends of the drive roller are fixedly sleeved with baffles that contact the side wall of the main body of the pipe, and the drive roller is rotatably inserted into the sliding frame.

[0010] Furthermore, a first motor is fixed to the side wall of one of the sliding frames, and the shaft of the first motor is fixedly connected to the drive roller.

[0011] Furthermore, a second motor is fixedly installed on the outer wall of the support box, and the shaft of the second motor is connected to a double-threaded lead screw.

[0012] Furthermore, the ends of the two double-threaded lead screws furthest from the second motor are each fixedly fitted with synchronous pulleys through the support box, and a synchronous belt is fitted between the two synchronous pulleys.

[0013] Furthermore, an installation cylinder is embedded within the coating cotton, and an installation shaft that is rotatably inserted into the support box is fixed within the installation cylinder.

[0014] Furthermore, the inner wall of the support box is fixed with a scraper that abuts against the coating cotton, and the top of the scraper is fixed with a load-bearing plate that is connected to the inner wall of the support box at equal intervals.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model features adjustable sliding frames fixed in grooves on both sides of the top surface of the support box. The drive roller between the two sliding frames on the same side supports the main body of the pipe, and the baffles at both ends of the drive roller position the main body of the pipe to prevent it from slipping between the two drive rollers. The first motor drives the drive roller to rotate, which in turn drives the main body of the pipe to rotate. During the rotation, the paint cotton comes into contact with the main body of the pipe, which facilitates the spraying of the rotating main body of the pipe and improves the spraying effect of the main body of the pipe.

[0018] By embedding a double-threaded screw in the slide groove, the second motor drives the sliding frame to move in the slide groove during rotation. During the movement of the sliding frame, the distance between the two baffles is adjusted, and the pipe body is tightly connected to the coating cotton during the adjustment process. It is suitable for rotary spraying of pipe bodies of different sizes. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is an automatic rotating device for producing anti-corrosion pipe fittings, and its structural schematic diagram is shown below. Figure 1 and Figure 2As shown, the automatic rotating equipment for producing anti-corrosion pipe fittings includes a support box 1 and drive rollers 2 symmetrically arranged at the top of the support box 1. The top ends of the two drive rollers 2 are clamped to the pipe fitting body 4. Slide grooves 10 are opened on both sides of the top surface of the support box 1. Double threaded screws 6 are rotatably installed in the two slide grooves 10. The two ends of the two double threaded screws 6 with opposite thread directions are threadedly sleeved with sliding frames 5 connected to the drive rollers 2. Coating cotton 15 is rotatably arranged in the support box 1 and contacts the outer wall of the pipe fitting body 4.

[0027] Both ends of the drive roller 2 are fixedly fitted with baffles 3 that contact the side wall of the pipe body 4. The drive roller 2 is rotatably inserted into the sliding frame 5. One of the sliding frames 5 has a first motor 8 fixed to its side wall. The shaft of the first motor 8 is fixedly connected to the drive roller 2. The drive roller 2 between the two sliding frames 5 on the same side supports the pipe body 4. The baffles 3 at both ends of the drive roller 2 position the pipe body 4 to prevent the pipe body 4 from slipping between the two drive rollers 2. The first motor 8 drives the drive roller 2 to rotate, which in turn drives the pipe body 4 to rotate. During the rotation, the coating cotton 15 comes into contact with the pipe body 4.

[0028] like Figure 3 and Figure 4 As shown, a second motor 9 is fixedly installed on the outer wall of the support box 1. The shaft of the second motor 9 is connected to a double-threaded screw 6. The ends of the two double-threaded screws 6 away from the second motor 9 pass through the support box 1 and are fixedly sleeved with synchronous pulleys 13. A synchronous belt 12 is sleeved between the two synchronous pulleys 13. An installation cylinder 14 is embedded in the coating cotton 15. An installation shaft 7 is fixed in the installation cylinder 14 and rotatably inserted into the support box 1. A scraper 11 that abuts against the coating cotton 15 is fixed on the inner wall of the support box 1. A load-bearing plate 16 connected to the inner wall of the support box 1 is fixed at equal distances at the top of the scraper 11. When the second motor 9 rotates, it causes the double-threaded screw 6 to drive the sliding frame 5 to move in the slide groove 10 during the rotation. The two sets of double-threaded screws 6 rotate simultaneously through the synchronous pulleys 13 and the synchronous belt 12. During the movement, the sliding frame 5 adjusts the distance between the two baffles 3 and makes the pipe body 4 tightly connected to the coating cotton 15.

[0029] Working principle: When using the device of this technical solution, the pipe body 4 is placed between two drive rollers 2. The drive rollers 2 between the two sliding frames 5 on the same side support the pipe body 4, and the baffles 3 at both ends of the drive rollers 2 position the pipe body 4 to prevent the pipe body 4 from slipping between the two drive rollers 2. When the second motor 9 is started, the double threaded screw 6 drives the sliding frame 5 to move in the slide groove 10 during the rotation. The two sets of double threaded screws 6 rotate simultaneously through the synchronous pulley 13 and the synchronous belt 12. During the movement of the sliding frame 5, the distance between the two baffles 3 is adjusted, and during the adjustment, the pipe body 4 is tightly connected to the coating cotton 15. When the first motor 8 is started, the drive rollers 2 are rotated, which drives the pipe body 4 to rotate. During the rotation, the coating cotton 15 comes into contact with the pipe body 4, which facilitates the spraying of the rotating pipe body 4 and improves the spraying effect of the pipe body 4.

[0030] All technical features in this embodiment can be freely combined according to actual needs.
