Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing, and in particular to a multi-layer bonding processing device for steel-lined polyurethane composite pipes. Background Technology

[0002] In the complex operating conditions of modern industry, pipeline systems, as key carriers of material transmission, face extremely stringent performance requirements. Steel-lined polyurethane composite pipes, with their unique performance advantages, have been widely used in many fields. The polyurethane lining provides excellent wear resistance, acid and alkali resistance, scale prevention, and resistance to hydrolytic aging, effectively resisting the erosion of various corrosive media and particulate materials, and greatly extending the service life of the pipeline.

[0003] In the multi-layer bonding processing equipment for steel-lined polyurethane composite pipes, polyurethane spraying plays a crucial role. The sprayed polyurethane material can quickly form a dense and continuous elastomer film on the surface of the steel pipe. On the one hand, due to its excellent adhesion properties, it firmly bonds with the inner wall of the steel pipe to form a stable composite structure, thereby enhancing the overall strength and toughness of the pipe.

[0004] Existing technologies often use fixed-size slots or clamps, which are difficult to adapt to composite pipes of different diameters and are prone to loose fixing. This can cause the composite pipe to shake or shift during the painting process, which is not conducive to meeting diverse production needs. Utility Model Content

The outer wall of the second threaded rod 21 is threadedly connected to the inside of the first rotating column 22.

[0029] Specifically, the support frame 16 is used to fix the third motor 20. During the rotation of the third motor 20, the second threaded rod 21 will rotate. During the rotation of the second threaded rod 21, it will rotate inside the first rotating column 22.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A second motor 13 is fixedly connected to the outer wall of the slide plate 12. A bidirectional threaded rod 14 is fixedly connected to the output end of the second motor 13.

The slide plate 12 is connected to the inside of the slide plate 12; the first light bar 11 is fixedly connected to the inside of the workbench 1, and the slide plate 12 is slidably connected to the outer wall of the first light bar 11; the upper surface of the workbench 1 is fixedly connected to the U-shaped frame 2, the upper surface of the U-shaped frame 2 is fixedly connected to the spray chamber 3, one end of the suction pipe 4 is fixedly connected to the inside of the spray chamber 3, the other end of the suction pipe 4 is fixedly connected to the pump 5, the lower surface of the pump 5 is fixedly connected to the upper surface of the U-shaped frame 2; the output end of the pump 5 is fixedly connected to one end of the discharge pipe 6, the other end of the discharge pipe 6 is fixedly connected to the spray box 7, and the inner wall of the spray box 7 is fixedly connected to the nozzle 8.

[0031] Specifically, the slide plate 12 is used to fix the second motor 13. During rotation, the second motor 13 drives the bidirectional threaded rod 14 to rotate, and the bidirectional threaded rod 14 rotates inside the slider 15. The slide plate 12 is used to fix the second optical bar 29, which in turn limits the movement of the slider 15. The worktable 1 is used to fix the first motor 9. During rotation, the first motor 9 drives the first threaded rod 10 to rotate, and the first threaded rod 10 rotates inside the worktable 1. The worktable 1 is used to... The first light bar 11 serves a fixing function and limits the sliding plate 12. The worktable 1 serves to fix the U-shaped frame 2, which in turn fixes the material pump 5 and the spraying bin 3. The spraying bin 3 holds polyurethane spray coating. When in use, the material pump 5 is started, and the pump 5 creates a negative pressure inside the spraying bin 3 through the suction pipe 4, which draws out the coating and then through the discharge pipe 6 into the spray box 7. Finally, the coating is evenly sprayed out through the nozzle 8 to process the composite tube.

[0032] Working principle: When the composite pipe needs to be fixed, the third motor 20 is started. The output end of the third motor 20 rotates, thereby driving the second threaded rod 21 to rotate. During the rotation of the second threaded rod 21, the first rotating column 22 moves, which in turn drives the third fixing block 24 to move. The third fixing block 24 then drives the transmission rod 26 to move through the second rotating column 25. During the movement of the transmission rod 26, the first fixing block 18 moves upward through the second rotating column 25. This movement of the first fixing block 18 then drives the support block 27 to move. During this process, the first fixing block 18 slides on the inner wall of the slot 17 opened in the support frame 16, thereby achieving the effect of fixing composite pipes of different diameters. This helps to prevent the composite pipe from shaking or shifting during the painting process, ensuring the uniformity and accuracy of multi-layer bonding processing.

[0033] When the composite pipe needs polyurethane spraying, the first motor 9 is started. The rotation of the output end of the first motor 9 drives the first threaded rod 10 to rotate, so that the first threaded rod 10 rotates inside the worktable 1. During this process, the rotation of the first threaded rod 10 drives the slide plate 12 to move. When the slide plate 12 passes under the U-shaped frame 2, the suction pump 5 is started, which causes the paint in the spraying chamber 3 to enter the suction pump 5 through the suction pipe 4, and then enter the spraying box 7 through the discharge pipe 6, and finally be sprayed out by the nozzle 8. At this time, the composite pipe can be sprayed, thereby achieving the effect of automated and precise spraying, which is conducive to improving the painting efficiency of composite pipe, reducing human operation errors, and enhancing the practicality and processing stability of the equipment.

[0034] When the composite tube needs to be clamped, the second motor 13 is started. The output end of the second motor 13 rotates, thereby driving the bidirectional threaded rod 14 to rotate. When the bidirectional threaded rod 14 rotates, it rotates inside the slide plate 12. In turn, the bidirectional threaded rod 14 drives the slider 15 to move during the rotation, thereby achieving the effect of initial positioning of the composite tube. This is beneficial for providing a precise reference for subsequent fixing operations and ensuring the stability of the composite tube's position during processing.
