Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to an automatic wire cutting device. Background Technology

[0002] Wires often need to be cut during use to enable them to conduct electricity to different electrical components. Existing cutting equipment usually relies on a traction device to pull the cable to a suitable length before cutting it with a cutting device. Since the traction device pulls the cable to a taut state, it is inevitable that the cable will break apart after being cut due to its own tension. The operator then needs to clamp the cut cable end back onto the clamping device to continue the cutting operation. This is cumbersome, inefficient, and makes it difficult to achieve continuous cutting operations. Utility Model Content

[0003] In view of this, the present invention provides an automatic wire cutting device, which can achieve continuous, stable and efficient cutting of cables without the need for clamping devices or frequent clamping and fixing of the cables to be cut, greatly improving cutting efficiency, saving time and effort, and making operation simpler and more convenient.

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic wire cutting device, including a base. A cable reel placement frame, a guide assembly, and a cutting assembly are sequentially arranged on the base along the direction of cable cutting. The reel-shaped cable is rotatably mounted on the cable reel placement frame. The guide assembly includes a fixing frame located between the cable reel placement frame and the cutting assembly, and a wire cylinder is mounted on the fixing frame. The cutting assembly includes a mounting frame mounted on the base, and a cutting roller and a pressing roller are rotatably mounted on the mounting frame. The cable to be cut passes sequentially through the guide cylinder and the channel between the cutting roller and the pressing roller. This utility model can automatically, efficiently, continuously, and rapidly cut the cable on the cable reel placement frame using the guide assembly in conjunction with the cutting assembly. Simultaneously, it avoids the problem of the cut cable breaking apart due to its own tension after being severed, requiring frequent machine stops and cable clamping before continuing the cutting operation, thus greatly improving the cable cutting efficiency.

[0005] The tangent roller has a slot, and a cutter is provided on the side wall of one of the slots.

[0006] The mounting frame is U-shaped, with grooves on both vertical side walls. A slider is slidably installed in each groove, and an adjustment frame is installed between the two sliders. The extrusion roller is rotatably installed between the two adjustment frames via a connecting shaft.

[0007] The upper part of the adjustment frame is equipped with a bearing, and a rotating shaft is rotatably installed inside the inner ring of the bearing. The outer side of the rotating shaft located at the upper part of the shaft is provided with an external thread. The adjustment frame is provided with a threaded hole that matches the external thread, and the rotating shaft is threaded into the threaded hole.

[0008] An adjustment disc is provided on the upper part of the rotating shaft, and an internal hexagonal hole is provided on the adjustment disc.

[0009] The axis of the guide cylinder passes between the highest point of the tangential roller and the lowest point of the extrusion roller.

[0010] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0011] 1. Improved cutting efficiency and continuity: This utility model can achieve automated and continuous cutting of coiled cables through the synergistic effect of the guide component (fixed frame + wire tube) and the cutting component (cutting roller + extrusion roller), avoiding the problem of frequent machine stops for fixing due to cable breakage in traditional cutting, and significantly improving work efficiency.

[0012] 2. Prevents cable breakage and ensures operational safety: This invention utilizes the slots of the tangent roller to fix the cable, and in conjunction with the pressure roller to apply pressure, effectively suppresses the release of cable tension at the moment the cutter completes the cut, preventing the cut section from breaking off. This reduces safety hazards, avoids downtime for maintenance, and ensures process continuity.

[0013] 3. Adaptable to various cable specifications, easy to adjust: This invention utilizes the sliding groove, slider, and adjustment frame structure on the U-shaped mounting bracket, combined with a threaded transmission mechanism (rotating shaft + bearing + adjusting disc), to quickly and accurately adjust the distance between the extrusion roller and the tangent roller. It easily adapts to the clamping requirements of cables of different diameters and simplifies blade replacement.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-3 As shown: This embodiment provides an automatic wire cutting device, including a base 100. A cable reel holder 200, a guide assembly 300, and a cutting assembly 400 are sequentially arranged on the base 100 along the direction of cable cutting. A reel-shaped cable is rotatably mounted on the cable reel holder 200. The guide assembly 300 includes a fixing frame 301 located between the cable reel holder 200 and the cutting assembly 400. A wire cylinder 302 is mounted on the fixing frame 301. The cutting assembly 400 includes a mounting frame 410 mounted on the base 100. A cutting roller 420 and a pressing roller 430 are rotatably mounted on the mounting frame 410. A rotating handle is provided on the outside of 420. The operator can rotate the cutting roller 420 by holding the rotating handle. The cable to be cut passes through the guide cylinder and the channel between the cutting roller 420 and the extrusion roller 430 in sequence. This utility model can automatically, efficiently and continuously cut the cable on the cable reel rack 200 by using the guide component 300 in conjunction with the cutting component 400. At the same time, it can avoid the problem that the cut cable will break after being cut due to its own tension, which would require frequent machine stops and the cable to be fixed and clamped before continuing the cutting operation. This greatly improves the cutting efficiency of the cable.

[0021] According to one embodiment of the present invention, such as Figure 1-3As shown, the tangent roller 420 has a slot 421, and a cutter 422 is provided on the side wall of one side of the slot 421. This utility model can realize the clamping and fixing of the cable through the slot 421. With the help of the cutter 422 and the extrusion roller 430 on the upper part of the tangent roller 420, the cable can be automatically cut under the driving action of the rotation of the tangent roller 420. The operation is more convenient. Moreover, the cooperation between the extrusion roller 430 and the tangent roller 420 can prevent the cable from automatically breaking off after being cut due to its own tension.

[0022] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the mounting bracket 410 is U-shaped. Slide grooves 411 are provided on the two vertical side walls of the mounting bracket 410. A slider 412 is slidably disposed within each slide groove 411. An adjustment bracket 413 is disposed between the two sliders 412. The extrusion roller 430 is rotatably disposed between the two adjustment brackets 413 via a connecting shaft. This invention allows for convenient and efficient adjustment of the distance between the extrusion roller 430 and the cutting roller by adjusting the height of the adjustment bracket 413, greatly improving the replacement of blades on the cutting roller and the clamping and fixing of cables of different diameters, making operation more convenient.

[0023] A bearing 500 is provided on the upper part of the adjusting frame 413. A rotating shaft 600 is rotatably mounted inside the inner ring of the bearing 500. An external thread is provided on the outer side of the rotating shaft 600 located on the upper part of the rotating shaft 600. A threaded hole adapted to the external thread is opened on the adjusting frame 413. The rotating shaft 600 is threaded into the threaded hole. By turning the rotating shaft 600, and with the cooperation between the external thread on the outer side of the rotating shaft 600 and the threaded hole of the adjusting frame 413, the rotating shaft 600, along with the adjusting frame 413 and the slider 412, can move up and down along the slide rail. This allows for convenient and efficient adjustment of the distance between the extrusion roller 430 and the cutting roller, making the operation more convenient.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, an adjustment disc 700 is provided on the upper part of the rotating shaft 600. The adjustment disc 700 has an internal hexagonal hole. This utility model provides a labor-saving and high-precision adjustment method through the design of the adjustment disc 700 and the internal hexagonal hole on the top of the rotating shaft 600. By rotating the rotating shaft 600 to drive the slider 412 to move vertically, the height of the extrusion roller 430 can be finely adjusted, making the operation intuitive and efficient.

[0025] The axis of the guide cylinder passes through the channel between the highest point of the tangent roller 420 and the lowest point of the extrusion roller 430. This utility model can achieve the effect of the guide cylinder. The axis of the guide cylinder strictly passes through the channel between the highest point of the tangent roller 420 and the lowest point of the extrusion roller 430, so that the cable always enters the cutting area along the preset trajectory, avoiding poor cutting or equipment jamming caused by skew, and improving the consistency of finished products.

[0026] How to use this utility model:

[0027] First, it should be clarified that the cutting device involved in this utility model is mainly used for automatic cable cutting. This utility model takes the cutting of wires during use as an example to describe its usage method in detail. When it is necessary to cut the wire, the operator first places the cable reel to be cut on the cable clamping disc, then inserts the bushing of the cable clamping disc into the rotating shaft on the cable reel placement frame 200, and then the operator rotates the rotating handle at the end of the cutting disc to rotate the cable clamping groove on the cutting disc to the appropriate position. Then the cable on the cable clamping disc passes through the guide cylinder and is clamped into the clamping groove 421. Then, the operator rotates the rotating handle on the outside of the cutting disc, causing the cutting disc to rotate while the cable rotates around the outside of the cutting disc. In the process, the extrusion disc and the cutter 422 work together to achieve continuous and efficient cutting of the cable. This utility model can achieve automated and continuous cutting of disc-shaped cables through the coordinated action of the guide component 300 (fixed frame 301 + wire cylinder 302) and the cutting component 400 (cutting roller 420 + extrusion roller 430), avoiding the problem of frequent machine stops for fixing due to cable breakage in traditional cutting, and significantly improving work efficiency.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
