Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, specifically relating to an automatic cable cutting device with safety protection. Background Technology

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of conductors. After the cable is manufactured, it needs to be packaged and transported. At this time, a cable cutting machine is needed to cut the cable to a suitable length to facilitate the packaging and transportation of the cable.

[0003] However, when cutting cables, if only one cable fixing mechanism is installed on both sides of the cutting blade at the top of the cutting table, it is difficult to fully restrain the cable. A single fixing mechanism refers to a specific existing device with only one fixing / clamping mechanism on one side of the cutting blade. When the cutting blade contacts the cable and applies cutting force, the cable is highly likely to deviate due to uneven force. Once the cable deviates, the cutting position cannot accurately match the predetermined cutting line, and the cut cable, in terms of length, cut smoothness, and other critical dimensions, is very likely to fail to meet the established process requirements. Based on the above problems, this application proposes an automatic cable cutting device with safety protection to improve these issues. Utility Model Content

[0004] The purpose of this invention is to provide an automatic cable cutting device with safety protection. The device uses a motor on a fixed plate to drive a threaded rod to rotate, causing the clamping plates to move in opposite directions and securely fix the cable. At the same time, the auxiliary pressure plate on the connecting rod fits tightly against the cable, preventing displacement and shaking during cable cutting, thus improving the accuracy and quality of cable cutting.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] An automatic cable cutting device with safety protection includes a cutting table. A fixing plate, a base, and two support frames are sequentially fixed to the upper end of the cutting table from one side to the other. A motor is fixed to one side of the upper end of the fixing plate. A threaded rod is fixed to the output end of the motor, and clamping plates are threaded to both ends of the outer side of the threaded rod. A support plate is fixed to the upper end of the base. An electric push rod is fixed to the upper end of the support plate. The output end of the electric push rod extends to the lower end of the support plate. A connecting plate is fixed to the output end of the electric push rod and located at the lower end of the support plate. A cutting blade is fixed to the lower end of the connecting plate.

[0007] In a preferred embodiment, the threaded rod has two external threads on its outer side, and the two external threads have opposite directions of rotation.

[0008] In a preferred embodiment, both of the two clamping plates have anti-slip surfaces on their sides that are close to each other.

[0009] In a preferred embodiment, the upper end of the fixing plate is provided with sliding grooves on both sides, and the two clamping plates are fixed with sliding plates on both sides, and the sliding grooves and sliding plates are compatible.

[0010] In a preferred embodiment, a movable plate is fixed to the side of the connecting plate away from the fixed plate, a circular plate is slidably connected inside the movable plate, a connecting rod is fixed to the lower end of the circular plate, the lower end of the connecting rod extends to the lower end of the movable plate, a pressure plate is fixed to the lower end of the connecting rod, and a spring is provided inside the movable plate and at the upper end of the circular plate.

[0011] In a preferred embodiment, a rotating rod is rotatably connected between the two support frames, and a guide wheel is fixed to the outer side of the rotating rod.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model uses a motor mounted on a fixed plate to drive a threaded rod to rotate. The rotation of the threaded rod causes the threaded clamping plates connected to it to move towards each other, which can accurately and firmly fix the cable. At the same time, a pressure plate is set at the end of the cutting blade away from the clamping plate. During the descent of the cutting blade, the connecting rod assists the pressure plate in closely fitting the cable, preventing the cable from shifting or shaking during the cutting process, thus improving the accuracy and quality of cable cutting.

[0020] 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.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model 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 this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] 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 this utility model. The phrase "in a preferred 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 mutually excludes other embodiments.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0024] Please see the appendix Figures 1 to 2 As shown, this utility model provides an automatic cable cutting device with safety protection, including a cutting table 10. A fixing plate 11, a base 20, and two support frames 30 are fixed sequentially from one side to the other on the upper end of the cutting table 10. A motor 12 is fixed on one side of the upper end of the fixing plate 11. A threaded rod 13 is fixed to the output end of the motor 12, and clamping plates 14 are threaded to both ends of the outer side of the threaded rod 13. A support plate 21 is fixed to the upper end of the base 20. An electric push rod 22 is fixed to the upper end of the support plate 21. The output end of the electric push rod 22 extends to the lower end of the support plate 21. A connecting plate 23 is fixed to the output end of the electric push rod 22 and located at the lower end of the support plate 21. A cutting blade 24 is fixed to the lower end of the connecting plate 23. Two external threads are opened on the outer side of the threaded rod 13, and the two external threads have opposite directions of rotation.

[0025] In this embodiment, when the cable needs to be cut, the cable to be cut is placed between two clamping plates 14, and the motor 12 on the fixing plate 11 is started. (The motor 12 is electrically connected to an external power supply via wires and is powered by an external power supply.) The output end of the motor 12 is fixed with a threaded rod 13. When the motor 12 starts, it drives the threaded rod 13 to rotate. Because there are two opposite external threads on the outside of the threaded rod 13, and both opposite external threads are threaded to clamping plates 14, when the threaded rod 13 rotates, the two clamping plates 14 located inside the fixing plate 11 will move towards each other along the threaded rod 13 under the action of the threads until the clamping plates 14 tightly clamp the cable, thereby achieving a stable fixation of the cable. After the cable is fixed, the electric push rod 22 supported by the support plate 21 on the base 20 is started. The output end of the electric push rod 22 drives the connecting plate 23 and the cutting blade 24 below to move downward. The cutting blade 24 contacts and cuts the cable, completing the cutting operation.

[0026] Secondly, please refer to it again. Figure 2 Both of the two clamping plates 14 have anti-slip surfaces on their sides that are close to each other.

[0027] In this embodiment, the two clamping plates 14 are provided with anti-slip surfaces on their sides that are close to each other, which effectively increases the friction between the two clamping plates 14 and the cable, making the cable more securely fixed.

[0028] Secondly, please refer to the following as well. Figure 2 The upper end of the fixed plate 11 has grooves 15 on both sides, and the two clamping plates 14 have slide plates 16 fixed on both sides, and the grooves 15 and slide plates 16 are compatible.

[0029] In this embodiment, because the upper end of the fixing plate 11 has grooves 15 on both sides, and the two clamping plates 14 are fixed with matching sliding plates 16 on both sides, when the two clamping plates 14 move, the sliding plates 16 will slide along the grooves 15, which will guide the clamping plates 14 so that they can move smoothly along a predetermined trajectory, thereby moving closer to or away from the cable for fixing or loosening operations.

[0030] To further understand and explain, Figure 3 and Figure 4 For example, a movable plate 25 is fixed on the side of the connecting plate 23 away from the fixed plate 11. A circular plate 26 is slidably connected inside the movable plate 25. A connecting rod 27 is fixed at the lower end of the circular plate 26. The lower end of the connecting rod 27 extends to the lower end of the movable plate 25. A pressure plate 28 is fixed at the lower end of the connecting rod 27. A spring 29 is provided inside the movable plate 25 and at the upper end of the circular plate 26.

[0031] In this embodiment, when the cable is cut, the electric push rod 22 is activated, which drives the connecting plate 23 to move downward. Since the moving plate 25 is fixed on the side of the connecting plate 23 away from the fixed plate 11, the moving plate 25 will move downward accordingly. When the pressure plate 28 contacts the cable, as the connecting plate 23 continues to descend, the spring 29 is compressed, the circular plate 26 slides upward inside the moving plate 25, and the connecting rod 27 also moves upward relative to the moving plate 25. At this time, the pressure plate 28 presses the cable tightly under the elastic force of the spring 29 and the push of the connecting rod 27. When the cutting is completed, the electric push rod 22 drives the connecting plate 23 to rise, the spring 29 gradually returns to its original state, and the circular plate 26, the connecting rod 27 and the pressure plate 28 also reset.

[0032] It should be noted that, in the initial state, the height of the pressure plate 28 is lower than the height of the cutting blade 24. When cutting the cable, the pressure plate 28 first fixes the cable, and the cutting blade 24 then cuts the cable. A cutting groove is provided at the upper end of the base 20 and directly below the cutting blade 24 to facilitate the cutting of the cable.

[0033] In a preferred embodiment, please refer to Figure 1 A rotating rod 31 is rotatably connected between the two support frames 30, and a guide wheel 32 is fixed on the outer side of the rotating rod 31.

[0034] In this embodiment, when the cable is placed on the cutting table 10 in preparation for cutting, the cable needs to pass over the guide wheel 32. Before cutting, as the cable is moved, the guide wheel 32 will rotate on the rotating rod 31. The rotation of the guide wheel 32 can effectively reduce the friction of the cable during the movement, allowing the cable to pass through the cutting area more smoothly, improving the efficiency of cable transport during the cutting process, and avoiding damage to the cable surface due to excessive friction.

[0035] The working principle of this utility is as follows:

[0036] During operation, the cable is first placed between two clamping plates 14 on the cutting table 10. The motor 12 on the fixed plate 11 is started, and the motor 12 drives the threaded rod 13 with reverse threads to rotate, causing the clamping plates 14 to move towards each other and clamp the cable. At the same time, the sliding plates 16 on both sides of the clamping plates 14 slide along the sliding grooves 15 on the fixed plate 11 to guide the cable. The anti-slip surface of the clamping plates 14 increases the friction with the cable. After the cable is fixed, the electric push rod 22 supported by the support plate 21 on the base 20 is started, which drives the connecting plate 23 and the cutting blade 24 to descend and cut the cable. Before cutting, the pressure plate 28 in the moving plate 25 on one side of the connecting plate 23 first presses the cable under the action of the spring 29. During cutting, the cable passes over the guide wheel 32 on the rotating rod 31 that is rotatably connected between the two support frames 30. The rotation of the guide wheel 32 reduces the friction of the cable movement, ensuring that the cable passes smoothly through the cutting area, completing the automatic, stable and safe cutting operation of the cable.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
