Description

Technical Field

[0001] This utility model relates to the technical field of pipe winding equipment, and in particular to a pipe winding equipment with automatic tension adjustment. Background Technology

[0002] Automatic tension-adjustable pipe winding equipment is a specialized device used in pipe processing to automatically wind and coat pipes. Through the coordinated work of the frame, winding rollers, feeding components, and other structures, it realizes the automated operation of pipe coating, which can improve the efficiency and quality of pipe coating and is widely used in the field of pipe production and processing.

[0003] In existing pipe winding and coating technologies, most equipment can only achieve simple winding of the membrane onto the pipe, with the membrane directly connected to the pipe. Throughout the winding process, there is no effective tension adjustment mechanism in the middle. This leads to fluctuations in the tension of the membrane as the diameter of the membrane roll on the winding roller changes during the coating process, making it prone to loosening. Loose membranes do not adhere tightly to the pipe, affecting not only the appearance quality of the pipe coating but also reducing the membrane's protective effect. Furthermore, the membrane is prone to detachment during subsequent pipe transportation or use. Therefore, this application provides a pipe winding device with automatic tension adjustment to meet this requirement. Utility Model Content

A rocker arm is rotatably connected to the top end of the drive shaft. The shaft of the feeding roller is rotatably connected to one end of the rocker arm, and an adjustment groove is provided inside the rocker arm.

[0010] Optionally, a bidirectional lead screw is rotatably connected to the top of the fixed plate, and a slip ring is symmetrically threaded to the outer side of the bidirectional lead screw. A pin is fixedly connected to the top of the slip ring, and the pin slides inside the adjustment groove.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] In the above-mentioned solution, the automatic tension-adjusting pipe winding equipment provided in this application uses the pushing action of the spring in the fixed box on the slide table to keep the tension roller constantly stretching the winding film, ensuring the tension of the film during the winding process, avoiding the problem of loose film and poor adhesion to the pipe due to the lack of tension adjustment mechanism, and significantly improving the appearance and protective effect of pipe coating.

[0015] The opening and closing degree between the two feeding rollers can be adjusted by rotating the bidirectional screw through the handwheel, which can adapt to pipes of different diameters for feeding and coating operations. There is no need to equip separate equipment for pipes of different diameters, which reduces the cost of use and improves the practicality and economy of the equipment.

[0031] like Figures 1 to 4As shown, an embodiment of this utility model provides an automatic tension-adjusting pipe winding device, including a frame 1. A support frame 28 is fixedly connected to the top of the frame 1. A fixing ring 2 is fixedly connected to the top of the frame 1 and to one side of the support frame 28. A rotating ring 3 is rotatably connected to the inner side of the fixing ring 2. A first motor 4 is fixedly connected to the base of the frame 1. The first motor 4 and the rotating ring 3 are connected by belt drive. A mounting shaft is rotatably connected to one side of the rotating ring 3. A winding roller 5 is detachably connected to the mounting shaft. The support frame 28 can support the pipe, and the support frame 28 is equipped with... The rotatable roller can better transport the pipe. The first motor 4 drives the rotating ring 3 to rotate, so that the winding roller 5 can rotate around the pipe at the center of the rotating ring 3. The winding roller 5 rotates outside the rotating ring 3 and can rotate on its own axis during the revolution, so as to achieve the coating of the pipe. The tension adjustment component is used to adjust the winding tension. The tension adjustment component is connected to the rotating ring 3. The feeding component is used to drive the pipe to be continuously fed. The feeding component is connected to the frame 1. The drive component is used to drive the feeding component to work. The drive component is connected to the frame 1.

[0032] In this embodiment, as Figure 4 and Figure 5 As shown, the tension adjustment assembly includes a fixed box 6 fixed to one side of the rotating ring 3. A slide table 7 is slidably connected inside the fixed box 6. A tension roller 8 is rotatably connected to one side of the slide table 7. A spring 9 is fixedly connected between one side of the inner wall of the fixed box 6 and the slide table 7. Since the film on the winding roller 5 passes through the tension roller 8 before winding the pipe, and the fixed box 6 is equipped with a spring 9, the slide table 7 can be pushed by the spring 9, thereby making the tension roller 8 always stretch the winding film, maintaining the tension of the film wound on the pipe, and preventing the phenomenon of film separation from the pipe due to insufficient tension.

[0033] In this embodiment, as Figures 1 to 3As shown, the feeding assembly includes a buckle plate 10 fixed to the top of the frame 1. A bearing roller 11 is rotatably connected inside the buckle plate 10. A constraint groove 101 is symmetrically formed inside the buckle plate 10. A feeding roller 15 is symmetrically arranged above the buckle plate 10, and the shaft of the feeding roller 15 extends to the bottom of the buckle plate 10 through the constraint groove 101. A fixing plate 12 is fixedly connected inside the frame 1. A drive shaft 13 is symmetrically rotatably connected inside the fixing plate 12. A rocker arm 14 is rotatably connected to the top of the drive shaft 13. The shaft of the feeding roller 15 is rotatably connected to one end of the rocker arm 14. An adjustment groove 19 is formed inside the rocker arm 14. A rocker arm 14 is rotatably connected to the top of the fixing plate 12. A bidirectional lead screw 16 is provided, with symmetrical threaded connections of slip rings 17 on its outer side. A pin 18 is fixedly connected to the top of the slip ring 17, and the pin 18 slides inside the adjusting groove 19. One end of the bidirectional lead screw 16 passes through the frame 1 and is fixedly connected to a handwheel 20. The handwheel 20 drives the bidirectional lead screw 16 to rotate, which can move the two slip rings 17 and the corresponding pins 18. Since the pin 18 of the rocker arm 14 slides in the adjusting groove 19 inside the rocker arm 14, the slip rings 17 and the pins 18 can drive the rocker arm 14 to rotate, which can change the opening and closing degree between the two feeding rollers 15 to adapt to pipes of different diameters and improve the applicability.

[0034] In this embodiment, as Figure 3 As shown, the drive assembly includes a mounting base 21 fixed on the frame 1. A second motor 22 is fixedly connected to the top of the mounting base 21. A worm gear 23 is fixedly connected to the output end of the second motor 22. A worm wheel 24 is fixedly connected to the outside of the drive shaft 13, and the worm wheel 24 meshes with the worm gear 23. A gear disc 25 is fixedly connected to the outside of the drive shaft 13. A transmission gear 26 is symmetrically rotatably connected to the top of the fixed plate 12. The gear disc 25 and the transmission gear 26 mesh with each other. A driven gear 27 is fixedly connected to the shaft of the feeding roller 15 through the rocker arm 14. 27 meshes with the gear disc 25. The second motor 22 drives the worm 23 and worm wheel 24 to rotate, which can drive one of the transmission shafts 13 to rotate. At this time, the transmission shaft 13 drives the corresponding gear disc 25 to rotate. At the same time, the gear disc 25, in conjunction with two transmission gears 26, drives the gear disc 25 on the other transmission shaft 13 to rotate. Meanwhile, the gear disc 25 drives the driven gear 27 at the bottom of the feeding roller 15 to rotate. At this time, the feeding roller 15, in conjunction with the bearing roller 11, can drive the pipe to move, and in conjunction with the rotating ring 3 and the winding roller 5, wrap and coat the pipe.

[0035] The working principle of this utility model:

[0036] Rotating the handwheel 20 drives the bidirectional lead screw 16, which is fixedly connected to it, to rotate on the top of the fixed plate 12. Since the outer side of the bidirectional lead screw 16 is symmetrically threaded with slip rings 17, and the pin 18 at the top of the slip ring 17 is embedded in the adjusting groove 19 inside the rocker arm 14, as the bidirectional lead screw 16 rotates, the two slip rings 17 will move synchronously in opposite directions along the lead screw axis. The pin 18 slides in the adjusting groove 19 and generates a thrust on the rocker arm 14. One end of the rocker arm 14 is rotatably connected to the top of the drive shaft 13, and the other end is rotatably connected to the shaft of the feeding roller 15. Under the thrust of the pin 18, the rocker arm 14 rotates around the top of the drive shaft 13, thereby driving the two feeding rollers 15 to move up and down along the constraint groove 101 on the buckle plate 10, changing the opening degree between the two feeding rollers 15 until feeding. The spacing between roller 15 and the bearing roller 11 inside the buckle plate 10 is adapted to the diameter of the pipe to be processed. One end of the pipe to be coated is placed on the bearing frame 28. The rotatable shaft roller on the bearing frame 28 can reduce the friction between the pipe and the bearing frame 28. The pipe is pushed so that the other end of the pipe passes through the center position inside the fixing ring 2 until the middle section of the pipe is within the encirclement of the winding roller 5. At the same time, it is ensured that the bottom of the pipe is in contact with the surface of the bearing roller 11 inside the buckle plate 10. The second motor 22 in the drive assembly is started. The second motor 22 is fixed on the top of the mounting base 21. Its output end drives the worm gear 23 to rotate. The worm gear 23 is meshed with the worm wheel 24 fixed on the outside of the transmission shaft 13. The rotation of the worm gear 23 drives the worm wheel 24 and one of the transmission shafts 13 fixed thereto to rotate synchronously. A gear disc 25 is fixed to the outside of the drive shaft 13. The gear disc 25 meshes with the drive gear 26 that rotates symmetrically on the top of the fixed plate 12. As the gear disc 25 rotates, the two drive gears 26 drive the gear disc 25 on the other drive shaft 13 to rotate synchronously in the opposite direction. At the same time, the two gear discs 25 mesh with the driven gear 27 fixed after the shaft of the feeding roller 15 passes through the rocker arm 14. The rotation of the gear disc 25 drives the driven gear 27 and the feeding roller 15 to rotate. At this time, the friction generated by the rotation of the feeding roller 15, combined with the support of the bearing roller 11, drives the pipeline to move continuously and uniformly in the horizontal direction. During the movement of the pipeline, the rotatable shaft roller on the bearing frame 28 rotates synchronously with the pipeline to assist in the smooth conveying of the pipeline. The first motor 4 is started in conjunction with the belt. The rotating ring 3 rotates around the inner axis of the fixed ring 2, driving the winding roller 5 on the mounting shaft to revolve around the axis of the pipe. Simultaneously, because the wrapping film on the winding roller 5 is attached to the pipe surface via the slide table 7, the tension generated on the wrapping film as the pipe continues to move will drive the winding roller 5 to rotate around the axis of the mounting shaft. The winding roller 5 rotates synchronously during its revolution, ensuring that the wrapping film is evenly released and wound onto the pipe surface. During the release of the wrapping film by the winding roller 5, the wrapping film first passes through the tension roller 8 in the tension adjustment assembly before being wound onto the pipe surface. The fixing box 6 of the tension adjustment assembly is fixed to one side of the rotating ring 3. The slide table 7 is slidably connected inside the fixing box 6, and the tension roller 8 is rotatably connected to one side of the slide table 7. A spring 9 is fixed between the inner wall of the fixing box 6 and the slide table 7.When the diameter of the film roll on the winding roller 5 changes, causing fluctuations in the tension of the stretch film: If the tension decreases, the elastic force of the spring 9 will push the slide 7 to slide inside the fixed box 6, thereby causing the tension roller 8 to move away from the winding roller 5, stretching the stretch film to increase tension. If the tension increases, the tension of the stretch film on the tension roller 8 will compress the spring 9, causing the slide 7 to slide closer to the winding roller 5, appropriately releasing the tension. Through the elastic action of the spring 9, the positions of the slide 7 and the tension roller 8 can be adjusted in real time to ensure that the tension roller 8 always exerts a stable tensile force on the stretch film, avoiding looseness or excessive tightness of the stretch film, and ensuring a tight fit between the film and the pipeline.
