Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel-reinforced plastic composite pipe production technology, specifically to a weft disc support structure for steel-reinforced plastic composite pipe production. Background Technology
[0002] In the production process of steel-reinforced plastic composite pipes, weft wires are wound onto the weft reel to provide weft yarn for the composite pipe production. The weft reel needs to be stably supported by a support structure to ensure that it can rotate normally and continuously and stably output weft yarn.
[0003] In existing weft reel support structures, the connection between the bottom circular flange of the guide post and the roller end cover is such that half of the internal thread is on the guide post flange and the other half is on the bottom of the roller end cover. After the guide post and roller end cover are inserted and fitted, they are locked in place by set screws. Simultaneously, the insertion interface between the guide post and roller end cover is circular, and the relative rotation between the guide post and roller end cover is constrained by the set screws between them.
[0004] In actual production, frequent replacement of weft reels is required. During this process, an open-end wrench is used to loosen or tighten the nut. The force applied by the wrench is transferred to the set screw between the guide post and the roller end cap. Over time, this can break the set screw, causing the guide post to separate from the roller end cap and rotate with the nut. This delays the weft reel replacement time. Furthermore, the weft reel cannot be effectively locked in place, causing it to rotate radially while being impacted by its own weight, potentially leading to it falling off. This not only damages the weft reel and the supporting structure but can also disrupt production, resulting in economic losses.
[0005] To address these issues, a weld is typically used to encircle the guide post flange edge and the seam where it meets the roller end cover. While this method ensures a more secure connection between the guide post and the roller end cover, preventing issues like incomplete locking and reel slippage, it also makes disassembly quite difficult when replacing the weft reel due to the welding, increasing equipment maintenance costs and complexity. Utility Model Content
[0006] The purpose of this utility model is to provide a support structure for the weft reel in steel-reinforced plastic composite pipe production. This support structure allows the guide column and the roller end cover to rotate together, avoiding affecting the time for replacing the weft reel, locking the weft reel in place, and facilitating the replacement of the weft reel.
[0007] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: a steel-framed plastic composite pipe production weft disc support structure, including a support base;
[0008] The weft reel is coaxially sleeved on the support base and can rotate on the support base;
[0009] A guide assembly, which is coaxially mounted on the support base;
[0010] A locking assembly is provided on the guide assembly and can lock the weft reel onto the support.
[0011] The guide assembly includes a roller end cap, which is disposed on the support base;
[0012] A guide post, on which the locking assembly is provided, and which penetrates the roller end cover;
[0013] Fastener, wherein the fastener is disposed between the roller end cap and the guide post;
[0014] Polygonal groove; the polygonal groove is coaxially disposed at the bottom of the roller end cover;
[0015] A limiting plate is coaxially disposed at the bottom of the guide post and is inserted into the polygonal slot.
[0016] In some embodiments, the support includes a support shaft seat;
[0017] A support roller, which is coaxially sleeved on the support shaft seat;
[0018] Two bearings are fitted onto the support shaft seat, and the support roller is fitted onto the two bearings.
[0019] In some embodiments, the guide assembly further includes a plug slot, which is coaxially disposed on the top of the roller end cap and connected to the polygonal groove;
[0020] At least two first mounting holes, the first mounting holes penetrating the inner top wall of the polygonal groove;
[0021] At least two second mounting holes are provided, which penetrate the limiting plate and are coaxially arranged with the first mounting hole. The fasteners are detachably connected between the second mounting holes and the first mounting holes.
[0022] In some embodiments, the cross-section of the limiting disk is a regular hexagon.
[0023] In some embodiments, the fastener is an internal hexagon head screw.
[0024] In some embodiments, the locking assembly includes a pressing member, which is coaxially sleeved on the guide post and presses against the weft reel;
[0025] A locking nut is screwed into the guide post, and the bottom of the locking nut is pressed against the pressing member.
[0026] In some embodiments, a braking assembly is further included, the braking assembly including a mounting base, the mounting base being fixedly connected to the support shaft seat;
[0027] A threaded hole that penetrates the mounting base;
[0028] An adjusting block, wherein the adjusting block is screwed into the threaded hole;
[0029] A connecting rod, which passes through the adjusting block;
[0030] A brake plate is located at the end of the connecting rod away from the adjusting block and is attached to the support roller;
[0031] A brake spring is disposed between the adjusting block and the brake plate and is sleeved on the connecting rod.
[0032] In summary, this utility model has the following beneficial effects:
[0033] This invention features a limiting plate at the bottom of the guide post and a polygonal groove at the bottom of the roller end cover that engages with the limiting plate. By constraining the limiting plate through the polygonal groove, the limiting plate is prevented from rotating within the groove, thus avoiding the guide post and locking assembly from rotating together. This prevents the weft reel from being improperly locked, affecting the time required to replace the weft reel. Furthermore, when disassembling or tightening the locking assembly, the invention can distribute the force transmitted from the locking assembly to the roller end cover and guide post, thereby reducing the force transmitted to the fasteners and preventing them from being cut.

[0041] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0042] refer to Figure 1-6 A steel-reinforced plastic composite pipe production weft reel support structure includes a support base 1, a weft reel 2, a guide assembly 3, and a locking assembly 4. The support base 1 is the basic load-bearing component of the entire support structure, providing stable support for the installation and rotation of the weft reel 2. The weft reel 2 is coaxially sleeved on the support base 1 and can rotate on the support base 1. The guide assembly 3 is coaxially mounted on the support base 1 and can guide and position the locking assembly 4, ensuring that the locking assembly 4 can accurately and stably lock the weft reel 2 onto the support base 1. The locking assembly 4 is mounted on the guide assembly 3 and can reliably lock the weft reel 2 onto the support base 1, ensuring that the weft reel 2 will not loosen or shift during the production of the steel-reinforced plastic composite pipe.
[0043] The guide assembly 3 includes a roller end cap 31, a guide post 32, a fastener 33, a polygonal groove 34, a limiting plate 35, a plug-in groove 36, at least two first mounting holes 37, and at least two second mounting holes 38. The roller end cap 31 is mounted on the support base 1 and can be made of aluminum alloy. The roller end cap 31 is coaxially mounted on the support roller 12 and can be connected by positioning pins and bolts to ensure coaxiality and connection stability between the two. The guide post 32 is equipped with a locking assembly 4, which can be connected by bolts and can be made of high-strength alloy steel. The top of the roller end cap 31 is coaxially provided with a plug-in groove 36, which can be plugged into the guide post 32. The bottom of the roller end cap 31 is coaxially provided with a polygonal groove 34, which connects to the plug-in groove 36. The bottom of the guide post 32 is coaxially provided with a limiting plate 35. 5. The limiting plate 35 can be inserted into the polygonal groove 34. The multiple faces of the polygonal groove 34 can limit the position of the limiting plate 35 within the polygonal groove 34, preventing relative rotation between the limiting plate 35 and the polygonal groove 34. Thus, during the disassembly or tightening of the locking assembly 4, the force applied by the open-end wrench will be transmitted to the fastener 33 between the guide post and the roller end cover, as well as between the limiting plate 35 and the polygonal groove 34. The constraint of the inner wall of the polygonal groove 34 on the rotation of the limiting plate 35 can share this force, thereby reducing the magnitude of the force transmitted to the fastener 33 and preventing long-term damage to the fastener 33. The guide post 32 separates from the roller end cover 31 and rotates together with the locking assembly 4, thus affecting the time for replacing the weft reel. This ensures that the weft reel is effectively locked in place and prevents the weft reel from falling off.
[0044] The top wall of the polygonal groove 34 is provided with a first mounting hole 37, and the limiting plate 35 is provided with a second mounting hole 38. The second mounting hole 38 and the first mounting hole 37 are coaxially arranged. Both the second mounting hole 38 and the first mounting hole 37 can be threaded holes. The fastener 33 can be screwed into the second mounting hole 38 and the first mounting hole 37 to achieve a tight connection between the guide post 32 and the roller end cover 31.
[0045] In some embodiments, the limiting disc 35 has a regular hexagonal cross-section. The regular hexagon can limit the rotation of the guide post 32 within the roller end cover 31, ensuring the stability of the guide post 32's position during operation, thereby ensuring the stable operation of the locking assembly 4.
[0046] In some embodiments, the fastener 33 may be an internal hex socket head cap screw. By tightening the screw with an internal hex wrench, the guide post 32 can be firmly fixed to the roller end cap 31, ensuring the overall structural stability and reliability of the guide assembly 3.
[0047] In some embodiments, the support base 1 includes a support shaft seat 11, a support roller 12, and two bearings 13. The support shaft seat 11 may be made of high-strength alloy steel to ensure sufficient strength and rigidity, enabling it to remain stable under complex working conditions without deformation or damage. The support roller 12 is coaxially sleeved on the support shaft seat 11. The support roller 12 may be made of wear-resistant cast iron. The two bearings 13 are sleeved on the support shaft seat 11, and the support roller 12 is sleeved on the two bearings 13. The bearings 13 may be high-precision deep groove ball bearings. The two bearings 13 ensure that the support roller 12 can rotate flexibly and smoothly on the support shaft seat 11, providing reliable support and a rotational foundation for the normal operation of the weft disc 2.
[0048] In some embodiments, the locking assembly 4 includes a pressing member 41 and a locking nut 42. The pressing member 41 is coaxially sleeved on the guide post 32 and pressed onto the weft reel 2. The pressing member 41 may include structures such as a chuck, a patterned disc, and a pressure plate, which are existing technologies and will not be described in detail here. The locking nut 42 is screwed into the guide post 32, and the bottom of the locking nut 42 is pressed onto the pressing member 41. By rotating the locking nut 42, the pressing member 41 can be pushed to move downward along the guide post 32, thereby pressing the weft reel 2 tightly onto the support roller 12.
[0049] In some embodiments, to further improve the control capability of the rotation of the weft reel 2 during the production process of steel-reinforced plastic composite pipe, a brake assembly 5 is also included. The brake assembly 5 includes a fixed seat 51, a threaded hole 52, an adjusting block 53, a connecting rod 54, a brake plate 55, and a brake spring 56. The fixed seat 51 can be made of high-strength steel and is fixedly connected to the support shaft seat 11 by welding. The threaded hole 52 passes through the fixed seat 51. The adjusting block 53 is screwed into the threaded hole 52. The connecting rod 54 passes through the adjusting block 53. The brake plate 55 is located at the end of the connecting rod 54 away from the adjusting block 53 and is attached to the support roller 12. The brake plate 55 can be an arc plate adapted to the outer surface of the support roller 12 to ensure that it can be tightly attached to the support roller 12 during braking and generate sufficient friction. During braking, the friction between the brake plate 55 and the support roller 12 can effectively prevent the rotation of the support roller 12, thereby achieving braking of the weft reel 2. The brake spring 56 is located between the adjusting block 53 and the brake plate 55, and is sleeved on the connecting rod 54. By rotating the adjusting block 53, it can be moved axially in the threaded hole 52, thereby adjusting the working state of the brake assembly 5.
[0050] When braking of the weft reel 2 is required, the adjusting block 53 is rotated to move it closer to the support roller 12, compressing the brake spring 56. The elastic force generated by the brake spring 56 pushes the brake plate 55 tightly against the support roller 12, achieving braking of the support roller 12 through friction, thereby preventing the rotation of the weft reel 2. When braking is not required, the adjusting block 53 is rotated in the opposite direction, the brake spring 56 returns to its original position, and the brake plate 55 separates from the support roller 12, allowing the weft reel 2 to rotate freely. The brake spring 56 ensures that the brake plate 55 operates smoothly and reliably during braking and release, and the braking force can be flexibly adjusted according to actual needs, meeting the requirements of different production processes for controlling the rotation of the weft reel 2.
[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
