Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, and specifically relates to a cable processing cable threading device. Background Technology

[0002] In the cable processing and manufacturing field, the cable production process typically includes key steps such as core drawing, insulation extrusion, sheath wrapping, and final winding. Among these, the extrusion process is the core link that imparts insulation performance and a specific outer structure to the cable, while cable threading and conveying is a crucial link connecting these processes and ensuring production continuity. As a key piece of equipment for cable threading and conveying during cable processing, the performance of the cable threading rack directly affects the cable production efficiency and product quality. Currently, most cable threading racks on the market primarily guide cables along a predetermined path, meeting certain production needs in basic cable threading and conveying. However, in actual cable processing and production, especially when working in conjunction with extruders and winding equipment, existing cable threading racks have revealed many problems that urgently need to be addressed. During cable threading and conveying, tension control is one of the key factors affecting cable quality. When the cable tension is insufficient, the cable may shake or shift during insulation or sheath extrusion, resulting in uneven extruded layer thickness and even serious quality problems such as exposed wires, which greatly affects the cable's insulation performance and service life.

[0003] While existing cable pulling frames can achieve cable pulling and transportation to a certain extent, their ability to adjust and control cable tension is very limited. Most traditional cable pulling frames lack effective tensioning mechanisms and cannot flexibly adjust cable tension according to cable specifications, materials, and production process requirements. Even if some cable pulling frames are equipped with simple tensioning devices, these devices are usually fixed in structure and have a narrow adjustment range, making it difficult to meet the diverse needs of cable tension in different production scenarios. In addition, existing cable pulling frames do not provide sufficient support and guidance for cables during transportation, which can easily lead to uneven local stress on the cable during transportation, further exacerbating the problem of unstable tension and thus affecting the overall processing quality of the cable. Therefore, this utility model proposes a cable processing and pulling device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1 to 4This embodiment of the present invention provides the following technical solution: a cable processing cable threading device, comprising a base 1, two threading plates 2 symmetrically fixed to the top of the base 1, and threading holes 21 formed through the surface of the threading plates 2 for the cable body 4 to pass through. During actual cable threading, the cable body 4 passes between the two threading plates 2. It works in conjunction with other extruders, winding equipment, etc., on the production line to achieve conventional cable processing steps. It also includes...

[0024] An adjustable elastic tensioning mechanism for tensioning the cable body 4 between two cable threading plates 2 includes two side support seats 51 symmetrically welded and fixed at the top center of the base 1, an adjustable base block 52 adjustablely installed between the two side support seats 51, two elastic lifting plates 53 movably installed on the top of the adjustable base block 52, and a tensioning roller 54 rotatably installed between the two elastic lifting plates 53 via a rotating shaft. The tensioning roller 54 rolls in contact with the bottom of the cable body 4, which can effectively tension the cable body 4 during the cable threading process, ensuring that the cable body 4 has appropriate tension. This effectively avoids problems such as uneven extrusion layer thickness and loose winding caused by insufficient tension, thereby ensuring the processing quality of the subsequent cable.

[0025] The support guide roller assembly 3, which is set on the outside of the cable threading plate 2, can effectively support the tensioned cable body 4 and ensure the stable threading of the cable body 4.

[0026] In this embodiment, preferably, the adjustable base block 52 has an inner movable cavity 56 inside, and an inner movable seat plate 57 is slidably disposed in the inner movable cavity 56. A spring 58 is also installed in the inner movable cavity 56 relative to the bottom of the inner movable seat plate 57. The bottom end of the elastic lifting plate 53 moves through the inner movable cavity 56 and is fixed to the inner movable seat plate 57. Under the pushing action of the spring 58, the tension roller 54 can effectively push the cable body 4 upward and tighten it during daily cable threading, ensuring that the tension of the cable body 4 is appropriate during the cable threading process. In addition, due to the extensibility of the spring 58, when the cable body 4 is subjected to a large tension, the tension roller 54 can also be pressed down for elastic tensioning, ensuring the stable cable threading of the cable body 4.

[0027] In this embodiment, preferably, the bottom end of the spring 58 abuts against the inner wall of the bottom end of the inner movable cavity 56, and the top end of the spring 58 abuts against the bottom surface of the inner movable seat plate 57.

[0028] In this embodiment, preferably, the top surface of the adjustable base block 52 is symmetrically provided with two strip-shaped plate holes for the elastic lifting plate 53 to pass through, and the strip-shaped plate holes are connected to the inner movable cavity 56, so as to allow the elastic lifting plate 53 to pass through smoothly and subsequently lift and slide.

[0029] In this embodiment, preferably, the adjustable elastic tensioning mechanism further includes an adjustment structure 55, which is disposed between the side support 51 and the adjustable base block 52. The adjustment structure 55 includes a screw 552 welded and fixed to the side of the adjustable base block 52, a strip groove 551 formed on the surface of the side support 51 for the screw 552 to pass through and move, and a hand-tightening screw ring 553 screwed onto the end surface of the screw 552 and abutting against the outer surface of the side support 51. After the hand-tightening screw ring 553 is fully tightened, the screw 552 and the adjustable base block 52 can be closed. The adjustable base block 52 is locked in place to ensure its height stability. When the height of the adjustable base block 52 and the tension roller 54 needs to be adjusted according to the actual tension requirements, simply loosen the hand-tightening screw 553 counterclockwise, and then move the adjustable base block 52 up and down to adjust the height. This ensures that the tension roller 54 has a suitable tension force on the cable body 4. When the tension force is adjusted to be appropriate, tighten the hand-tightening screw 553 clockwise to fully tighten it, thereby locking the screw 552 and the adjustable base block 52 in place to meet different tension requirements.

[0030] In this embodiment, preferably, multiple strip-shaped protrusions 5531 are evenly distributed on the circumferential surface of the hand-tightening screw 553, which can play an anti-slip role when the operator tightens the hand-tightening screw 553 in the future, and facilitates rotation and tightening.

[0031] In this embodiment, preferably, the support guide roller assembly 3 includes two side plates 31 symmetrically welded and fixed to the outer surface of the cable threading plate 2 and located on both sides of the cable threading hole 21. A support roller 32 is rotatably mounted between the two side plates 31 via a rotating shaft, and the support roller 32 rolls in contact with the top surface of the cable body 4, which can ensure the height consistency of the cable body 4 before and after cable threading. At the same time, the diameter at both ends of the support roller 32 is 1.2 times the diameter at the center, making the two ends of the support roller 32 larger than the center. The cable body 4 is conveyed and threaded at the center of the support roller 32. The two ends of the support roller 32 can guide the cable body 4 during the cable threading process and prevent the cable body 4 from deviating during cable threading.

[0032] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
