Therefore, in the production and processing of prefabricated insulated pipes, the pipe fittings need to be sprayed and wound.

[0043] It should be noted that the present invention is a continuous spray winding device for the production of prefabricated insulation pipes. First, the staff can drive the fourth hydraulic rod 15 and drive the loading frame 16 to move downward to the lowest end. At this time, the loading frame 16 passes through the third through groove 14 on the feed frame 12 and moves downward until the loading frame 16 is located below the third through groove 14. Then the staff can place the pipe fittings 22 that need to be processed on the feed frame 12. At this time, under the inclined guiding action of the feed frame 12, the pipe fittings 22 can move to the top of the loading frame 16 by themselves through the feed frame 12 in the feed trough 11. Then, under the driving action of the fourth hydraulic rod 15, the pipe fittings 22 can be pushed upward by the loading frame 16. At the same time, the loading frame 16 can separate the next pipe fitting 22 to prevent the next pipe fitting 22 from moving to the third through groove 14 and causing it to detach.

[0044] After the pipe fitting 22 moves upward to between the first positioning block 504 and the second positioning block 9, the first hydraulic rod 3 and the third hydraulic rod 6 on the device housing 1 can be driven. Under the driving action of the first hydraulic rod 3 and the third hydraulic rod 6, the first mounting plate 4 and the second mounting plate 7 can be pushed to move toward the middle at the same time, thereby driving the first positioning block 504 and the second positioning block 9 to move toward the middle at the same time, so that the pipe fitting 22 can be conveniently and stably clamped and positioned, ensuring the convenience and stability of subsequent spraying and winding of the pipe fitting 22. After the pipe fitting 22 is clamped and positioned, the loading frame 16 on the fourth hydraulic rod 15 can be driven to move downward and reset, waiting for the loading of the next pipe fitting 22. In the process of clamping the pipe fitting 22, when the first mounting plate 4 and the second mounting plate 7 move toward the middle, the first mounting plate 4 can drive the support block 537 at the end of the reciprocating screw rod 507 to be inserted into the second mounting plate 7 for auxiliary support.

[0045] At this time, under the driving action of the servo motor 502, the first positioning block 504 can be driven to rotate stably through the rotating shaft 503 at the output end, and then the pipe 22 and the second positioning block 9 can be driven to rotate simultaneously, so as to ensure the stability of the rotation state of the pipe 22. At the same time, during the rotation of the rotating shaft 503, the first gear 505 can be driven to rotate simultaneously, and the second gear 506 meshingly connected on both sides can drive the corresponding reciprocating screw rod 507 to rotate simultaneously. At this time, under the rotation action of the reciprocating screw rod 507 on both sides, the sleeve 512 on the first transfer frame 509 can be driven to reciprocate on the pipe 22 through the threaded fixed block 508. Movement, during the reciprocating motion of the sleeve 512, the pipe fitting 22 always keeps rotating at a uniform speed, and under the action of the movement of the sleeve 512, it can drive the second transfer frames 523 on the upper and lower sides to move synchronously. At this time, under the action of the water pipe 524, the clean water can be stably transported to the second nozzle 525 on the second transfer frame 523 and sprayed. At the same time, combined with the reciprocating motion of the second nozzle 525 and the flexible brush 526 on the second transfer frame 523 and the uniform rotation of the pipe fitting 22, the automatic cleaning process of the outer wall of the pipe fitting 22 can be automatically completed, and the staff can set up wastewater recovery equipment in the device to recover wastewater.

[0046] After the outer wall of the pipe 22 is cleaned, the water transportation inside the water pipe 524 can be stopped. At this time, the small air pump 532 and the electric heating tube 531 on the insulation frame 530 are turned on. Under the driving action of the small air pump 532, the air is sucked through the first fixed tube 533, and the air can be discharged through the second fixed tube 534 on the insulation frame 530. During the air flow, it can be heated by each electric heating tube 531. At this time, under the movement of the sleeve 512, the insulation frame 530 on the fixed blocks 508 on both sides can be driven to reciprocate, and combined with the uniform rotation of the pipe 22, the outer wall of the pipe 22 can be automatically dried.

[0047] After the pipe 22 is cleaned and dried, the second hydraulic rod 516 can drive the rack 518 to move through the connecting plate 517 and drive the third gear 519 to engage and rotate. At this time, the third gear 519 drives the second transfer frame 523 on the connecting plate 522 to automatically rotate outward through the transmission shaft 520 on the limit plate 521, and moves out of the connecting groove 513 on the sleeve 512. At this time, the flexible brush 526 on the second transfer frame 523 moves out of the sleeve 512. At the same time, during the movement of the rack 518, the rubber piston 528 can be pushed to move into the gas storage frame 515 through the plug rod 527. At this time, the gas storage frame 515 can automatically move to the rubber airbag 514 through the air guide pipe 529. Dynamic inflation completes the automatic closing of the connecting groove 513, so as to avoid the polyurethane adhering to the flexible brush 526 during the subsequent polyurethane spraying process, which is inconvenient to clean and affects the stability of the subsequent working state of the flexible brush 526; similarly, under the reciprocating motion of the sleeve 512 and the uniform rotation of the pipe 22, the polyurethane is transported to the inside of the first transfer frame 509 through the guide pipe 510 and sprayed out through the first nozzle 511, so that the outer wall of the pipe 22 can be automatically and uniformly sprayed in all directions; and after the pipe 22 is sprayed, it can also pass through the first fixed tube 533 on the small air pump 532, combined with the second fixed tube 534 on the insulation frame 530 and each electric heating tube 531, to complete the drying process after spraying.

[0048] After the pipe fitting 22 completes the spraying treatment, it can drive the connecting plate 517 on the second hydraulic rod 516 to move and reset. At this time, the connecting plate 517 can drive the third gear 519 to rotate in the opposite direction through the rack 518, and then can drive the second transfer frame 523 to rotate into the connecting groove 513 through the connecting plate 522 on the transmission shaft 520, waiting for the next cleaning treatment. At the same time, under the movement of the rack 518, it can drive the rubber piston 528 on the plug rod 527 to move and reset, and then can automatically evacuate the rubber airbag 514 through the air guide pipe 529 on the air storage frame 515 to avoid the rubber airbag 514 from blocking the reset of the second transfer frame 523.

[0049] After the pipe fitting 22 has completed the spraying and drying treatment, the staff can pass the polyethylene film extruded by the polyethylene extruder through the second through groove 10, and guide it between the guide rollers 536 on both sides of the installation frame 535, and then wrap the end of the polyethylene film around the left end of the pipe fitting 22. Then, combined with the uniform movement of the sleeve 512 from left to right, the guide rollers 536 on both sides of the installation frame 535 can be used to push the polyethylene film to move synchronously, and combined with the uniform rotation of the pipe fitting 22, the polyethylene film can be automatically and evenly wrapped around the pipe fitting 22. After the winding is completed, the polyethylene film can be cut off to complete the continuous spraying and winding process of the prefabricated insulation pipe.

[0050] Subsequently, under the driving action of the fifth hydraulic rod 20, the extension plate 21 can be pushed to move downwardly toward the pipe fitting 22. At this time, under the driving action of the first hydraulic rod 3 and the third hydraulic rod 6, the first mounting plate 4 and the second mounting plate 7 can be pushed to move to the side at the same time, thereby driving the first positioning block 504 and the second positioning block 9 to move away from the pipe fitting 22. At this time, the pipe fitting 22 can fall onto the extension plate 21. At this time, under the inclined guiding action of the extension plate 21 and the internal unloading frame 19 of the unloading trough 18, the unloading work of the pipe fitting 22 can be automatically completed. Subsequently, through repeated operations, the continuous spraying and winding processing of the prefabricated insulation pipes can be completed in batches.
