Description

Technical Field

[0001] The present invention relates to the field of PE pipe coiling devices, and more particularly, to a coiling device for PE pipes. Background Art

[0002] A PE pipe coiling device is a coiling equipment for high-density polyethylene (PE) pipes. This device generally includes a sturdy frame and a rotating system to ensure that the pipe material can enter the coiling process at a constant speed, avoiding quality defects in the coiled pipes caused by jamming or uneven feeding, enabling the PE pipes to be neatly coiled together for convenient space management. The design of the coiling device takes into account the diameter and length of the pipes to ensure that even very long PE pipes can be effectively managed.

[0003] Due to its material, the PE pipe has good flexibility and plasticity. When coiling the PE pipe, under the continuous and uniform external force applied by the coiling device, the pipe body bends and gradually coils tightly. As the coiling operation progresses, not only is there a high morphological fit between the PE pipe and the coiling device, but also due to the tight contact, a large frictional force is generated between the two. Coupled with the flexibility of the PE pipe itself, which enables it to well conform to the shape of the coiling device, the degree of tight fitting is further aggravated. As a result, after the PE pipe is coiled, it is tightly attached to the coiling device, and thus it is difficult to remove from the coiling device.

[0004] How to invent a coiling device for PE pipes to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Example, referring to Figures 1 - 6 , a coiling device for PE pipes, including a base 1, a vertical frame 2 fixedly connected to the top of the base 1, a load-bearing seat 3 fixedly connected to the side wall of the vertical frame 2, a connecting plate 4 rotatably connected to the load-bearing seat 3, a ring gear 40 fixedly sleeved on the side wall of the connecting plate 4, a limiting seat 5 fixedly connected to the side wall of the connecting plate 4, and further including: a coiling component, the coiling component is arranged on one side of the limiting seat 5 and is used for coiling the PE pipe; a reciprocating component, the reciprocating component is arranged on the vertical frame 2 and is used for orderly winding the PE pipe; an auxiliary component, the auxiliary component is arranged on the vertical frame 2 and is used for fixing the coiled PE pipe. A plurality of limiting plates 50 are arranged on the limiting seat 5 at equal circumferential intervals, and a winding groove 6 is arranged on the limiting seat 5.

[0031] The reel assembly includes a plurality of rotating members 7 fixedly connected to the limit seat 5. The rotating members 7 are arranged at equal circumferential intervals on the limit seat 5. A coiling plate 8 is fixedly connected to the rotating member 7. The end cross-section of the coiling plate 8 is arc-shaped. A plurality of opening and closing plates 9 are arranged at the end of the coiling plate 8. The number of the opening and closing plates 9 is the same as that of the limit plates 50. A fixed sleeve 10 is fixedly connected to the limit seat 5. A moving tube 11 and an output shaft 13 are arranged inside the fixed sleeve 10. A sliding rod 12 is fixedly connected to the outer side wall of the moving tube 11. The fixed sleeve 10 and the moving tube 11 are slidably connected through the sliding rod 12. A threaded shaft 14 is fixedly connected to the end of the output shaft 13. The inner side wall of the moving tube 11 is in threaded fit connection with the threaded shaft 14. A plurality of fixed seats 15 are fixedly connected to the end of the moving tube 11. A connecting block 16 is fixedly connected to the end of the coiling plate 8. The connecting block 16 is located inside the coiling plate 8. The coiling plate 8 is rotatably connected to the opening and closing plate 9 through the connecting block 16. The fixed seat 15 is rotatably connected to the end of the opening and closing plate 9. A clamping seat 17 is fixedly connected to the outer side wall of the moving tube 11. A sliding shaft 171 is slidably connected inside the clamping seat 17. The sliding shaft 171 is non-rotatably arranged with the clamping seat 17. A clamping plate 172 is fixedly connected to one end of the sliding shaft 171. A spring 173 is fixedly connected to the other end of the sliding shaft 171. The end of the spring 173 is fixedly connected to the side wall of the moving tube 11. A ratchet assembly 18 is fixedly connected to the inner side wall of the load-bearing seat 3. A small gear 19 is rotatably connected to the ratchet assembly 18. The small gear 19 is meshed with the ring gear 40. A first motor 130 is fixedly connected to the vertical frame 2. The output end of the first motor 130 is fixedly connected to the output shaft 13. The load-bearing seat 3 and the first motor 130 are located on both sides of the vertical frame 2. A plurality of reinforcing ribs are arranged on the vertical frame 2.

[0032] It should be noted that the PE pipe to be coiled is inserted into the ring 28. By pulling the clamping plate 172 to separate it from the clamping seat 17, the end of the PE pipe is placed in the gap between the clamping plate 172 and the clamping seat 17. Since the clamping plate 172 is pulled by the spring 173 through the sliding shaft 171, the end of the PE pipe is fixed on the clamping seat 17, completing the preliminary preparation work of the PE pipe.

[0033] By starting the first motor 130, the output shaft 13 and the threaded shaft 14 are driven to rotate. The moving tube 11 is driven to rotate through the thread. Since the moving tube 11 is limited by the opening and closing plate 9 and remains in a state of relative rest with the threaded shaft 14, the fixed sleeve 10 is driven to rotate by the sliding rod 12 on the moving tube 11, driving the limit seat 5 to rotate on the connecting plate 4. The limit seat 5 drives the coiling plate 8 to move in a circular motion around the seat through the rotating member 7, so that the PE pipe is wound around a plurality of coiling plates 8, thus starting the coiling process.

[0034] It should be noted that by rotating the first motor 130 in the reverse direction, the output shaft 13 and the threaded shaft 14 are driven to rotate. Due to the setting of the ratchet assembly 18, the pinion 19 can only rotate in one direction. When the first motor 130 rotates in the reverse direction, the ring gear 40 remains fixed due to its meshing with the pinion 19, keeping the fixed sleeve 10 fixed. The moving pipe 11 moves towards the direction of the limit seat 5 due to the rotation of the threaded shaft 14, driving the opening and closing plate 9 to rotate on the connecting block 16 through the fixed seat 15. Since the connecting block 16 is located inside the coiling plate 8, the included angle between the opening and closing plate 9 and the coiling plate 8 increases, making the opening and closing plate 9 parallel to the coiling plate 8. The opening and closing plate 9 no longer blocks the coiled PE pipe, allowing the PE pipe to be removed from the device; during the process of the opening and closing plate 9 gradually becoming parallel to the coiling plate 8, since the opening and closing plate 9 also rotates on the fixed seat 15, the end of the coiling plate 8 also moves towards the direction of the moving pipe 11, thereby reducing the contact surface between the coiling plate 8 and the coiled PE pipe, facilitating the removal of the PE pipe from the device and preventing the PE pipe from consuming more time during the removal process.

[0035] Referring to Figures 7 - 8 , the reciprocating assembly includes a reciprocating frame 21 fixedly connected to the side wall of the vertical frame 2 and a second motor 22. The second motor 22 and the reciprocating frame 21 are located on both sides of the vertical frame 2. A support seat 23 is fixedly connected to the bottom of the reciprocating frame 21. The output end of the second motor 22 is fixedly connected to a lead screw 24. The support seat 23 is rotationally connected to the lead screw 24. A reciprocating seat 25 is connected to the lead screw 24 through a threaded fit. A reciprocating groove ²⁶ is provided on the reciprocating frame 21. The reciprocating seat 25 is slidably connected to the reciprocating frame 21 through the reciprocating groove 26. The top of the reciprocating seat 25 is fixedly connected to a shearing frame 27 and a ring 28. The ring 28 is located inside the shearing frame 27. The top of the shearing frame 27 is fixedly connected to a third motor 29. The output end of the third motor 29 is provided with a telescopic rod 30. The bottom end of the telescopic rod 30 is fixedly connected to a cutting knife 31. The cutting knife 31 is slidably connected to the inner side wall of the shearing frame 27.

[0036] It should be noted that by starting the second motor 22, the lead screw 24 is driven to rotate, and the reciprocating seat 25 is driven to move in the length direction of the reciprocating frame 21 through the thread, driving the ring 28 to move. By controlling the second motor 22 to move in the reverse direction, the PE pipe is orderly wound around the coiling plate 8, preventing the situation of multi-layer overlapping winding during the winding process.

[0037] By starting the third motor 29, the telescopic rod 30 is driven to extend, causing the cutting knife 31 to move in the vertically downward direction. The end of the cutting knife 31 exerts a shearing force on the PE pipe to cut the PE pipe. The tie strap is passed through the gap between the coiling plates 8 and the threading groove 6, and the tying process of the PE pipe is completed by tightening the tie strap.

[0038] Referring to Figure 9, the auxiliary component includes a fourth motor 41 fixedly connected to the top of the base 1. The output end of the fourth motor 41 is fixedly connected with an auxiliary rod 42. The end of the auxiliary rod 42 is fixedly connected with a swing rod 43. The end of the swing rod 43 is rotatably connected with a rolling rod 44. A bearing frame 45 is arranged on the top of the base 1. The top of the bearing frame 45 is fixedly connected with a push plate 46. The push plate 46 is arranged in a fitting manner with the vertical frame 2. The top of the bearing frame 45 is arranged in an arc shape. The bottom of the bearing frame 45 is slidably connected with the base 1 through a chute.

[0039] It should be noted that after the device completes the coiling process, by starting the fourth motor 41, the auxiliary rod 42 is driven to rotate, driving the swing rod 43 to swing, so that the rolling rod 44 presses the coiled PE pipe to prevent the PE pipe from loosening due to its own tension.

[0040] In this embodiment, the PE pipe to be coiled is inserted into the ring 28, and then the end of the PE pipe is fixed on the clamping seat 17. By starting the first motor 130, the limit seat 5 rotates on the connecting plate 4. The limit seat 5 drives the coiling plate 8 to move in a circular motion around the seat through the rotating part 7, so that the PE pipe is wound around a plurality of coiling plates 8. By controlling the forward and reverse rotation of the second motor 22, the PE pipe is wound on the coiling plate 8 in an orderly manner. After the device completes the coiling process, by starting the fourth motor 41, the rolling rod 44 presses the coiled PE pipe. By starting the third motor 29, the end of the cutting knife 31 applies a shearing force to the PE pipe to cut off the PE pipe, and finally the PE pipe is bundled to complete the working process of coiling the pipe.

[0041] By rotating the first motor 130 in the reverse direction, under the reverse locking action of the ratchet assembly 18, the moving pipe 11 moves towards the limit seat 5, making the opening and closing plate 9 in a parallel state with the coiling plate 8, so that the opening and closing plate 9 no longer blocks the coiled PE pipe. At the same time, since the opening and closing plate 9 also rotates on the fixed seat 15, the end of the coiling plate 8 also moves towards the moving pipe 11, thereby reducing the contact area between the coiling plate 8 and the coiled PE pipe, facilitating the removal of the PE pipe from the device. By moving the bearing frame 45 in the direction opposite to the vertical frame 2, the push plate 46 pushes the coiled PE pipe away from the hanging device to complete the process of removing the PE pipe from the device.

[0042] It should be noted that the specific model and specification of the motor need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here.

[0043] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
