Description

Technical Field

[0001] This utility model belongs to the field of aluminum stranded wire processing technology, specifically relating to a device for preventing strand breakage during wire cutting. Background Technology

[0002] Aluminum stranded wire is a type of bare conductor. In my country, aluminum-clad steel stranded wire is commonly used as the conductor. The steel core mainly serves to increase strength, while the aluminum stranded wire primarily transmits electrical energy. The cross-sectional area of ​​the conductor varies depending on the voltage. The processing of aluminum stranded wire involves multiple steps, including grinding, stretching, and cutting. During cutting, anti-stranding devices are used to limit the movement of multiple strands, ensuring the stability of the conductor's position during cutting.

[0003] Chinese invention patent CN110227774A discloses a wire cutting anti-stretching device. The first connecting arm is provided with several groups, and the multiple groups of first connecting arms are connected in sequence through a first pin and a connecting hole to form a flexible connecting arm. The first connecting arm at the head end is movably connected to the first protective cover through a third pin. The first connecting arm at the tail end is provided with a second connecting arm on one side, and the upper side of the second connecting arm is provided with several ratchet teeth.

[0004] The aforementioned patent uses a locking mechanism and ratchet to adjust the position and angle of multiple sets of first connecting arms, thereby limiting the wire in the middle. However, there are certain problems in actual use. Specifically, the multiple sets of first connecting arms are connected by a first pin. Although the angle can be adjusted stably, there are still gaps and spacing between the first connecting arms. Furthermore, as the first connecting arms tighten, they will squeeze the wire, causing indentations on the outer surface of the wire, which affects the overall stability of the device during use.

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A wire cutting anti-snagging device includes a connecting frame, a mounting frame, and a tightening belt. The connecting frame has mounting frames symmetrically installed at both ends. The mounting frame has a tightening belt inside to limit the wire. Inside the mounting frame and at the end of the tightening belt, there is a winding mechanism for adjusting the length of the tightening belt. The winding mechanism includes a connecting rod, a winding roller, and a rotating rod. The connecting rod is installed on one side inside the mounting frame and connected to one end of the tightening belt. The winding roller is installed on the other side inside the mounting frame and winds up the other end of the tightening belt. A rotating rod is installed at the end of the winding roller and is rotatably connected to the mounting frame.

[0008] As a preferred embodiment of this utility model, the tightening belt is made of soft aluminum alloy, and the aluminum alloy belt is wrapped with a rubber layer.

[0009] As a preferred embodiment of the present invention, the winding mechanism further includes a housing and a limiting component. The housing is mounted on the side of the mounting frame, and the limiting component is installed inside the housing.

[0010] As a preferred technical solution of this utility model, the limiting component includes a rotating gear, a locking plate, a pulling rod, and a spring assembly. The rotating gear is rotatably installed inside the housing and is connected to the rotating rod. The locking plate, which meshes with the rotating gear, is slidably installed inside the housing. A pulling rod is installed at the end of the locking plate and is slidably connected to the housing. A spring assembly is sleeved on the outside of the pulling rod.

[0011] As a preferred embodiment of this utility model, both the rotating gear and the positioning plate are equipped with trapezoidal toothed plates for cooperation, and one end of the spring assembly is connected to the positioning plate, while the other end of the spring assembly is connected to the inner wall of the outer shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a tightening belt and a winding mechanism. By adjusting the length of the tightening belt through the rotation of the winding roller, its overall inner diameter changes, thereby quickly and stably positioning and reinforcing the wire, facilitating stable cutting by subsequent cutting equipment. The material and structural design of the tightening belt itself reduces the gap between it and the wire, preventing the wire from falling out due to excessive gaps. Simultaneously, the extrusion mechanism compresses the sidewalls of the tightening belt against the winding roller and connecting rod, ensuring a more stable fit between the tightening belt and the wire, further enhancing the tightening effect.

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] Depend on Figure 1 As shown, this is a schematic diagram of the wire cutting and anti-fragmentation device in this embodiment. The device includes a connecting frame 1, a mounting frame 2, and a tightening band 3. The connecting frame 1 is symmetrically equipped with mounting frames 2 at both ends. The mounting frame 2 is equipped with a tightening band 3 for limiting the wire. The tightening band 3 is made of soft aluminum alloy strip and is wrapped with a rubber layer. The mounting frame 2 is equipped with a winding mechanism 4 for adjusting the length of the tightening band 3 inside the mounting frame 2 and located at the end of the tightening band 3.

[0027] After the wires that need to be limited are neatly arranged, they are placed inside the tightening belt 3. Then, under the action of the winding mechanism 4, the entire length of the tightening belt 3 is wound up, causing the inner diameter of the tightening belt 3 to change. The tightening belt 3 squeezes and clamps the wires to lock the wire position. The tightening belt 3 itself is made of soft aluminum alloy strip, which can fit as closely as possible to the outer wall of the wire, reducing the size of the gap between the tightening belt 3 and the wire and preventing the wire from falling out of the gap. The mounting frame 2 is provided with two sets to simultaneously limit both ends of the wire to be processed. The overall length of the connecting frame 1 can be adjusted and changed to facilitate limiting wires of different lengths.

[0028] From the appendix Figure 2 and Figure 3 As shown, this is a schematic diagram of the winding mechanism 4 in this embodiment. The winding mechanism 4 includes a connecting rod 41, a winding roller 42, a housing 43, a limiting component 44, and a rotating rod 45. The connecting rod 41 is installed on one side inside the mounting frame 2 and is connected to one end of the tightening belt 3. The winding roller 42 is installed on the other side inside the mounting frame 2 and winds up the other end of the tightening belt 3. The rotating rod 45 is installed at the end of the winding roller 42 and is rotatably connected to the mounting frame 2. The housing 43 is installed on the side of the mounting frame 2, and the limiting component 44 is installed inside the housing 43.

[0029] The wire to be positioned is inserted into the tightening belt 3. Then, by rotating the rotating rod 45, the winding roller 42 winds up one end of the tightening belt 3, causing the overall length of the tightening belt 3 to change. The tightening belt 3 positions the wire, and the rotation angle of the winding roller 42 is locked by the cooperation of the housing 43 and the limiting component 44 to prevent the winding roller 42 from retracting due to the compression of the wire after the tightening belt 3 is positioned.

[0030] From the appendix Figure 4 As shown, this is a schematic diagram of the limiting component 44 in this embodiment. The limiting component 44 includes a rotating gear 441, a locking plate 442, a pulling rod 443, and a spring assembly 444. The rotating gear 441 is rotatably installed inside the outer shell 43 and is connected to the rotating rod 45. The locking plate 442, which meshes with the rotating gear 441, is slidably installed inside the outer shell 43. The pulling rod 443 is installed at the end of the locking plate 442 and is slidably connected to the outer shell 43. The spring assembly 444 is sleeved on the outside of the pulling rod 443. Both the rotating gear 441 and the locking plate 442 are equipped with trapezoidal toothed plates for cooperation. One end of the spring assembly 444 is connected to the locking plate 442, and the other end of the spring assembly 444 is connected to the inner wall of the outer shell 43.

[0031] When the rotating rod 45 rotates to wind up the tensioning belt 3 outside the take-up roller 42, the rotating gear 441 rotates synchronously under the drive of the rotating rod 45. The locking plate 442 moves upward due to the pressure of the trapezoidal toothed plate outside the rotating gear 441. At this time, the spring assembly 444 enters the storage state, driving the locking plate 442 to slide closer to the rotating gear 441, so that the locking plate 442 re-engages with the rotating gear 441. The structure and shape of the trapezoidal toothed plate prevent the rotating gear 441 from retracting, ensuring the stability of the take-up roller 42 during the winding process.

[0032] From the appendix Figure 5 As shown, this is a structural schematic diagram of the extrusion mechanism 5 in this embodiment. It also includes the extrusion mechanism 5. The extrusion mechanism 5 is symmetrically installed on both sides of the mounting frame 2. The extrusion mechanism 5 includes a side housing 51, a movable plate 52, an extrusion frame 53, and an extrusion screw 54. The side housing 51 is installed on the side of the mounting frame 2. The movable plate 52 is slidably installed inside the side housing 51. The extrusion frame 53 is installed on the side of the movable plate 52. The extrusion screw 54 is rotatably installed at the end of the movable plate 52. The extrusion screw 54 is threadedly connected to the side housing 51.

[0033] After the tightening belt 3 has finished limiting the conductor, the extrusion screw 54 is rotated to push the moving plate 52, causing the extrusion frame 53 to slide closer to the tightening belt 3. The extrusion frame 53 extrudes the tightening belt 3 and pushes the connection between the tightening belt 3 and the connecting rod 41 and the winding roller 42, so that the tightening belt 3 fits better against the outer wall of the conductor.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
