Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable processing, more particularly to a parallel wire device for cable processing. BACKGROUND

[0002] Cable is a general term for optical cable, cable and other articles. Cable has many uses, mainly for control installation, connection of equipment, power transmission and other multiple functions, and is a common and indispensable thing in daily life. Since the cable is live, special care is needed during installation. Cable parallel wire is a process of connecting more than two cable power lines of the same type. The application scenarios of cable parallel wire include multi-strand cable parallel wire and single-strand hard copper wire parallel wire.

[0003] Different parallel wire methods may be required for cables of different materials and specifications. For example, the parallel wire method for copper conductors and aluminum conductors is different. The surface of the aluminum core wire is easily oxidized. If it is directly articulated or crimped, it may cause electrochemical corrosion, resulting in increased contact resistance and overheating, causing line failure. Therefore, aluminum conductors usually use tight pressure connection and use copper or aluminum sleeves to maintain the connection. In addition, for multi-strand cable parallel wire, the copper core of the multi-strand wire is soft and easy to connect, so the core wire can be twisted tightly first, then tightly wrapped around the core wire of another conductor, and finally the excess wire ends are cut off. If the tension between the cores is uneven or too large during cable parallel wire, the cores may break.

[0004] In the prior art, when the cable breaks during the parallel wire process, the core wire in a stretched state falls to the ground after rapid rebound. Although the cable processing site is cleaned regularly, impurities may still exist. If the impurities adhere to the surface of the core wire, an additional cleaning step is required before the parallel wire process can continue, which affects the processing efficiency of the cable.

When the driving disc stops rotating, the first and second magnetic blocks can continue to press the core through magnetic attraction.

[0021] (3) The striker contacts the pressure sensor after moving, and then the controller activates the warning light and turns off the driving disc. Since the core is locked after breaking, the warning light will be activated, which not only alerts the staff but also allows for timely processing of the core after the driving disc stops running, ensuring the quality of the parallelized core and reducing the frequency of defective cables.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0033] Please refer to Figures 1 to 8 A parallel wire device for cable processing, comprising a body 1 and a driving disc 11 arranged on the right side of the upper end of the body 1, and the right side of the driving disc 11 is provided with a locking part 2.

[0034] The locking part 2 comprises connecting strips 21 hingedly arranged in an annular array on the right side of the driving disc 11, the inner surfaces of the connecting strips 21 are fixedly connected with fixed cylinders 22, the inner walls of the fixed cylinders 22 are provided with moving grooves 23, the left and right sides inside the moving grooves 23 are slidingly connected with moving discs 24, the outer sides of the left and right corresponding moving discs 24 are fixedly connected with connecting supports 25, the connecting supports 25 are slidingly connected inside the moving grooves 23, and the right side of the moving disc 24 is fixedly connected with rubber sheets 26 in an annular array.

[0035] The connecting strip 21 is arranged obliquely, the shape of the moving disc 24 is matched with the shape of the moving groove 23, and the rubber sheet 26 is arranged obliquely.

[0036] By adopting the above technical scheme, the body 1 is provided with a wire core, the wire core is passed through the driving disc 11, then the wire core is pulled, so that the wire core passes through the fixed cylinder 22 fixed by the connecting strip 21, and in the process that the wire core passes through the fixed cylinder 22, the wire core passes through the plurality of rubber sheets 26 gathered together, so that the rubber sheets 26 are pushed away, when the wire core is broken due to excessive tension in the process of doubling, the wire core quickly rebounds in a taut state, in this process, because the plurality of rubber sheets 26 are always in contact with the outside of the wire core, when the wire core moves to the right, the wire core will spread the plurality of rubber sheets 26, so that the wire core can flow smoothly, and when the wire core reverses due to rebound, the stress points of the plurality of rubber sheets 26 change, so that the plurality of rubber sheets 26 begin to gather and tightly fit on the outside of the wire core, so that the wire core is difficult to continue to move, at the same time, the plurality of rubber sheets 26 are fixed on the side of the same moving disc 24, and the two moving discs 24 are fixed in the same connecting bracket 25, when the wire core pulls the rubber sheet 26 to the left, the connecting bracket 25 will be pushed in the moving groove 23 due to the pushing of the moving disc 24, when the connecting bracket 25 moves to the side of the moving groove 23, the connecting bracket 25 cannot continue to move, and the wire core locked by the rubber sheet 26 cannot continue to move, because the wire core is broken during doubling, the rebounding wire core will be locked by the plurality of rubber sheets 26, effectively avoiding the wire core from falling to the ground due to breakage, not only facilitating the reconnection of the wire core, but also saving the subsequent step of cleaning the impurities on the surface of the wire core, so that the doubling efficiency of the wire core is guaranteed.

[0037] As shown in Figures 4 to 8 The inner and outer parts of the fixed cylinder 22 are provided with a pressing assembly 27, and the pressing assembly 27 includes sliding grooves 271 opened on the front and back sides of the inner wall of the moving groove 23.

[0038] The sliding grooves 271 are slidably connected with sliding blocks 272, the sliding blocks 272 are fixedly connected to the back of the connecting bracket 25, the inner back of the sliding groove 271 is provided with a movable groove 273, the back of the sliding block 272 is fixedly connected with a first connecting plate 274, the first connecting plate 274 is slidably connected in the movable groove 273, the left side of the first connecting plate 274 is hingedly connected with a second connecting plate 275, the right end of the second connecting plate 275 is slidably connected in the movable groove 273, the front end of the second connecting plate 275 is fixedly connected with a snap ring 276 on the left side, the inner surface of the snap ring 276 is fixedly connected with rubber strips 277 in a transverse linear array, the upper and lower sides of the front end of the snap ring 276 are provided with first magnetic blocks 278, and the upper and lower sides of the inner surface of the connecting strip 21 are provided with second magnetic blocks 279.

[0039] The active slot 273 penetrates the left side of the fixed cylinder 22, the shape of the first connecting plate 274 and the shape of the second connecting plate 275 are matched with the shape of the active slot 273, and the first magnetic block 278 and the second magnetic block 279 are magnetically attracted.

[0040] By adopting the above technical scheme, as the connecting bracket 25 moves to the left, the slider 272 outside the connecting bracket 25 will slide in the sliding groove 271 inside the fixed cylinder 22, wherein the slider 272 located at the back side is fixed with the first connecting plate 274, and the first connecting plate 274 is inside the active slot 273, when the slider 272 drives the first connecting plate 274 to slide inside the active slot 273, the second connecting plate 275 hinged with the first connecting plate 274 will gradually move out of the active slot 273, but the active range of the sliding groove 271 is limited, when the second connecting plate 275 completely leaves the active slot 273, the slider 272 can only continue to move a small distance, because the driving disc 11 is in a rotating state, after the second connecting plate 275 leaves the active slot 273, it will move towards the direction of the connecting strip 21 due to the rotation of the driving disc 11, as the clasp 276 on the other side of the second connecting plate 275 contacts the connecting strip 21, after the driving disc 11 stops rotating, the second magnetic block 279 on the side of the clasp 276 will be magnetically adsorbed with the first magnetic block 278 on the side of the connecting strip 21, at this time the clasp 276 will also press the wire core, and the rubber strip 277 inside the clasp 276 will contact the outside of the wire core, so that the wire core is locked, because the rubber strip 277 wraps the wire core while the second connecting plate 275 that leaves the active slot 273 quickly presses the wire core through the clasp 276, further improving the locking effect of the wire core, and avoiding the wire core from falling to the ground due to breakage, and after the driving disc 11 stops rotating, the wire core can also be pressed by the magnetic adsorption of the first magnetic block 278 and the second magnetic block 279.

[0041] As shown in Figures 6 to 8 The outer side of the body 1 is provided with a warning assembly 28, and the warning assembly 28 comprises a pressure spring 281 fixedly connected to the left side of the slider 272.

[0042] The other end of the pressure spring 281 is fixedly connected to the inside left side of the sliding groove 271, the left side of the slider 272 is fixedly connected with a striker 282, the inside left side of the sliding groove 271 is provided with a pressure sensor 283, the pressure spring 281 wraps the outside of the striker 282 and the pressure sensor 283, and the striker 282 moves to be in extrusion contact with the right side of the pressure sensor 283, the front side of the body 1 is provided with a controller 284, and the front side of the body 1 is provided with a warning light 285.

[0043] By adopting the above technical scheme, when the slider 272 slides to the left inside the sliding groove 271, the slider 272 can drive the striker 282 to move and extrude the pressure spring 281. When the striker 282 contacts the pressure sensor 283 inside the sliding groove 271, the pressure sensor 283 transmits information to the controller 284. Subsequently, the controller 284 starts the warning light 285 while the controller 284 also closes the driving disc 11. Since the wire core is locked after being broken, the warning light 285 will be started, which not only warns the staff, but also facilitates the timely processing of the wire core after the driving disc 11 stops running, so as to ensure the quality of the wire core after doubling, and reduce the frequency of defective cable.

[0044] As shown in Figures 2 to 4 The right side of the driving disc 11 is provided with an adjusting component 3, which includes an electric push rod 31 arranged on the front and back sides of the right end of the driving disc 11.

[0045] The telescopic end of the electric push rod 31 is fixedly connected with a push disc 32. The inside of the push disc 32 is annularly arranged with a limiting groove 33. The inside of the limiting groove 33 is rotatably connected with a limiting rod 34. Adjacent left and right corresponding limiting grooves 33 form a group, and adjacent left and right corresponding limiting rods 34 form a group.

[0046] The outer side of the push disc 32 is annularly arranged with a movable collar 35. Each group of limiting rods 34 is respectively located on the left and right sides of the movable collar 35. The movable collar 35 is slidably sleeved on the outer side of the connecting strip 21.

[0047] By adopting the above technical scheme, when the wire core is broken, the staff processes the wire core in time, and then starts the electric push rod 31 to push or pull the push disc 32. After the push plate moves, the movable collar 35 sleeved on the outer side of the connecting strip 21 is connected with the limiting groove 33 in the inside of the push disc 32 through the limiting rod 34, and the limiting rod 34 fixed on the two sides of the movable collar 35 can rotate in the limiting groove 33. With the movable collar 35 moving on the outer side of the connecting strip 21 driven by the push disc 32, the movable collar 35 will push the connecting strip 21, so that the connecting strip 21 hinged on the right side of the driving disc 11 changes the inclination angle of the right side of the driving disc 11. At this time, the pulling force of the connecting strip 21 on the wire core will also change. Since the position of the push disc 32 adjusts the position of the movable collar 35, the connecting strip 21 changes the pulling force of the wire core by driving the fixed cylinder 22 to move, so that the tension of the wire core in the doubling process will change, so as to quickly adjust the tension of the wire core in the doubling process, thereby reducing the frequency of wire core breakage.

[0048] Working principle: the core passes through the fixed cylinder 22 in the process of the rubber sheet 26 will be pushed away, when the core is broken due to excessive tension in the process of parallel wire, the core quickly rebounds in the state of tension, when the core moves to the right side, the core will be stretched, so that the core can flow through, when the core moves in the opposite direction due to rebound, the stress point of the rubber sheet 26 changes, so that the rubber sheet 26 begins to gather and closely fit on the outside of the core, so that the core is difficult to continue to move, when the core pulls the rubber sheet 26 to the left, the connecting bracket 25 will be pushed by the moving disc 24 in the moving groove 23, when the connecting bracket 25 moves to the side of the moving groove 23, the connecting bracket 25 cannot continue to move, and the core locked by the rubber sheet 26 also cannot continue to move, the slider 272 on the back side is fixed with the first connecting plate 274, and the first connecting plate 274 is in the activity slot 273, when the slider 272 drives the first connecting plate 274 to slide in the activity slot 273, the second connecting plate 275 connected with the first connecting plate 274 will gradually move out of the activity slot 273, because the driving disc 11 is in rotating state, the second connecting plate 275 will move to the direction of the connecting strip 21 after being separated from the activity slot 273, when the clasp ring 276 on the other side of the second connecting plate 275 contacts with the connecting strip 21, the second magnetic block 279 on the side of the clasp ring 276 will be magnetically adsorbed with the first magnetic block 278 on the side of the connecting strip 21 after the driving disc 11 stops rotating, at this time the clasp ring 276 will also press the core, and the rubber strip 277 in the clasp ring 276 will contact with the outside of the core, so that the core is locked, when the slider 272 slides to the left in the sliding groove 271, the slider 272 can drive the striker 282 to move and press the pressure spring 281, when the striker 282 contacts with the pressure sensor 283 in the sliding groove 271, the pressure sensor 283 will transmit information to the controller 284, then the controller 284 starts the warning light 285, and the controller 284 also closes the driving disc 11, then the electric push rod 31 pushes or pulls the pushing disc 32, because the movable sleeve ring 35 outside the connecting strip 21 is connected with the limiting groove 33 in the pushing disc 32 through the limiting rod 34, when the pushing disc 32 drives the movable sleeve ring 35 to move outside the connecting strip 21, the movable sleeve ring 35 will push the connecting strip 21, so that the connecting strip 21 connected with the right side of the driving disc 11 changes the inclination angle of the right side of the driving disc 11, so that the tension of the core changes.

[0049] The above merely shows the preferred embodiments of the present application; however, the protection scope of the present application is not limited to this.
