Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a cutting mechanism for a cable stripping machine. Background Technology

[0002] A cable is a device used to transmit power, signals, or data. It consists of one or more insulated conductors and usually also includes a sheath, filler, and possibly other structural elements. The conductors of wires and cables are usually wrapped in insulation material. Stripping this layer of insulation material is the first step in connecting wires, which requires a stripping machine.

[0003] A search revealed a cable stripping device for cable production (publication number CN221806340U). The device includes a base plate with a fixed plate at its top center. A drive mechanism is mounted on the fixed plate, and a stripping mechanism is located on one side of the drive mechanism. The stripping mechanism includes a first motor fixedly mounted on the fixed plate, a first drive wheel fixedly mounted on the output shaft of the first motor, a first fixed shaft fixedly mounted on the fixed plate, and a first driven wheel rotatably connected to the first fixed shaft. Both the first drive wheel and the first driven wheel are equipped with cutting blades. This cable stripping device for cable production automatically drives the cable through the drive mechanism and strips the cable through the stripping mechanism. The device has a simple structure, is easy to carry, has high stripping efficiency, and facilitates cable stripping.

[0004] Based on the above patent, the cable is automatically driven by the set drive mechanism, and the cable is stripped by the set stripping mechanism. The device has a simple structure, is easy to carry, has high stripping efficiency, and is convenient for stripping cables. However, the above solution is not suitable for cables of different diameters. When encountering cables with smaller diameters, there may be insufficient cutting. In addition, the cutting blade needs to be replaced after long-term use. The above solution is not convenient for replacing the cutting blade.

[0005] In response to this technical problem, this application proposes a cutting mechanism for a cable stripping machine. Utility Model Content

By starting a second motor, the first bidirectional threaded rod is driven to rotate, thereby adjusting the position of the cutting body on the first moving plate to accommodate cables of different sizes. While the first bidirectional threaded rod rotates to adjust the position of the cutting body, the second bidirectional threaded rod can rotate synchronously through a transmission component, thereby adjusting the position of the separating plate according to the cable size to facilitate the separation of the cable sheath.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A cutting mechanism for a cable stripping machine includes a base plate. A first support frame is fixedly connected to the top right side of the base plate. A first motor is fixedly connected to the front end of the first support frame. A take-up drum is rotatably connected to the inner wall of the first support frame. The front end of the take-up drum is fixedly connected to the drive end of the first motor. A second support frame is fixedly connected to the top left side of the base plate. A connecting plate is connected to the rear side of the top of the second support frame via a first adjusting component. A cutting frame is provided at the bottom end of the connecting plate. A first rotating shaft is rotatably connected to the inner wall of the cutting frame. A roller is fixedly connected to the outer wall of the first rotating shaft.

A material distribution plate is connected to the middle of the inner wall of the base plate via a second adjusting component for adjusting the position of the material distribution plate.

[0009] Furthermore, the second adjustment component includes a second bidirectional threaded rod rotatably connected to the middle of the inner wall of the base plate, and a second movable plate is threadedly connected to both sides of the outer wall of the second bidirectional threaded rod. The bottom end of each material distribution plate is fixedly connected to the top end of the second movable plate.

[0010] Furthermore, the first adjustment component includes a second motor fixedly connected to the rear side of the top of the second support frame. The drive end of the second motor is fixedly connected to a first bidirectional threaded rod. Both sides of the outer wall of the first bidirectional threaded rod are threadedly connected to a first movable plate. The outer walls of the connecting plates are fixedly connected to the inner walls of the first movable plates. The bottom end of the first bidirectional threaded rod is rotatably connected to the inner wall of the base plate. The outer wall of the bottom end of the first bidirectional threaded rod is connected to the second bidirectional threaded rod through a transmission component.

[0011] Furthermore, the transmission assembly includes a second rotating shaft located on the outer wall of the bottom end of the first bidirectional threaded rod and fixedly connected to it by a transmission belt.

[0012] Furthermore, the gear assembly includes a driving bevel gear fixedly connected to the top of the second rotating shaft and a driven bevel gear fixedly connected to the rear end of the second bidirectional threaded rod, wherein the driving bevel gear meshes with the driven bevel gear.

[0013] Furthermore, the replacement component includes a connecting rod that is slidably connected to the inner wall of the connecting plate. A fixing block is fixedly connected to one outer end of the connecting rod. The fixing block is connected to the inner wall of the connecting plate by a spring. A pressing piece is fixedly connected to one inner end of the connecting rod.

[0014] Furthermore, the inner wall of the cutter holder is provided with fixing grooves on both sides, and the fixing block corresponds to the fixing groove.

[0015] Furthermore, one end of the spring is connected to the fixed block, and the other end of the spring is connected to the inner wall of the connecting plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by starting the second motor, the first bidirectional threaded rod is driven to rotate, thereby adjusting the position of the cutter body on the first moving plate to adapt to cables of different sizes. When the first bidirectional threaded rod rotates to adjust the position of the cutter body, the second bidirectional threaded rod can be rotated synchronously through the transmission component, thereby adjusting the position of the material distribution plate according to the size of the cable, so as to facilitate the distribution of the cable sheath.

[0018] 2. In this utility model, by pressing the two side plates, the two side fixing blocks are moved inward, thereby releasing the fixation between the cutter frame and the connecting plate.

[0025] 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.

[0026] Reference Figure 1-Figure 3 This utility model provides an embodiment of a cutting mechanism for a cable stripping machine, comprising a base plate 1, a first support frame 2 fixedly connected to the top right side of the base plate 1, a first motor 3 fixedly connected to the front end of the first support frame 2, a take-up drum 4 rotatably connected to the inner wall of the first support frame 2, the front end of the take-up drum 4 fixedly connected to the drive end of the first motor 3, a second support frame 5 fixedly connected to the top left side of the base plate 1, a second motor 6 fixedly connected to the rear side of the top of the second support frame 5, a first bidirectional threaded rod 7 fixedly connected to the drive end of the second motor 6, a first moving plate 8 threadedly connected to both sides of the outer wall of the first bidirectional threaded rod 7, a connecting plate 9 fixedly connected to the inner wall of the first moving plate 8, and the bottom end of the first bidirectional threaded rod 7 rotatably connected to the inner wall of the base plate 1. The outer wall of the second rotating shaft 15 is fixedly connected to the transmission belt 14. The bottom end of the second rotating shaft 15 is rotatably connected to the inner wall of the base plate 1. The top end of the second rotating shaft 15 is fixedly connected to the driving bevel gear 16 and the rear end of the second bidirectional threaded rod 18 is fixedly connected to the driven bevel gear 17. The driving bevel gear 16 and the driven bevel gear 17 mesh with each other. The bottom end of the connecting plate 9 is provided with a cutter holder 10. The inner wall of the cutter holder 10 is rotatably connected to the first rotating shaft 11. The outer wall of the first rotating shaft 11 is fixedly connected to the roller 12. The middle part of the outer wall of the roller 12 is fixedly connected to the cutter body 13. The middle part of the inner wall of the base plate 1 is rotatably connected to the second bidirectional threaded rod 18. The outer walls of the second bidirectional threaded rod 18 are threadedly connected to the second moving plate 19 on both sides. The bottom end of the material distribution plate 20 is fixedly connected to the top end of the second moving plate 19.

[0027] Specifically, when adapting to cables of different sizes, the second motor 6 is started, which drives the first bidirectional threaded rod 7 to rotate, thereby causing the first moving plates 8 on both sides to move inward or outward simultaneously. The movement of the first moving plates 8 adjusts the position of the cutter body 13 on the two rollers 12 to cut the cable. At this time, the rotation of the first bidirectional threaded rod 7 drives the second rotating shaft 15 to rotate synchronously through the transmission belt 14. Then, through the meshing between the driving bevel gear 16 and the driven bevel gear 17, the second bidirectional threaded rod 18 is driven to rotate. The rotation of the second bidirectional threaded rod 18 adjusts the position of the material distribution plate 20 on the two second moving plates 19, so that the material distribution plate 20 can synchronously adapt to the size of the cable, which is convenient for adjustment and improves the practicality of the device.

[0028] Reference Figure 1 and Figure 4 The connecting rod 23 is slidably connected to the inner wall of the connecting plate 9. A fixing block 21 is fixedly connected to one end of the outer side of the connecting rod 23. The fixing block 21 is connected to the inner wall of the connecting plate 9 by a spring 22. A pressing piece 24 is fixedly connected to one end of the inner side of the connecting rod 23. Fixing grooves are provided on both sides of the inner wall of the cutter holder 10. The fixing block 21 corresponds to the fixing groove. One end of the spring 22 is connected to the fixing block 21, and the other end of the spring 22 is connected to the inner wall of the connecting plate 9 for replacing the cutter body 13.

[0029] Specifically, when replacing the cutter body 13 on the roller 12, pressing the push plate 24 inward will move the connecting rods 23 on both sides inward, thereby moving the fixing block 21 inward, releasing the correspondence between the fixing block 21 and the fixing groove in the connecting plate 9, thus releasing the fixation between the connecting plate 9 and the cutter holder 10, making it easier to replace the cutter. When installing the cutter, by placing the cutter holder 10 in a suitable position, the elastic force of the spring 22 will move the fixing blocks 21 on both sides outward, thereby aligning them with the fixing groove, fixing the connecting plate 9 and the cutter holder 10, making it easier to replace the cutter.

[0030] Working Principle: To accommodate cables of different sizes, the system activates the second motor 6, which drives the first bidirectional threaded rod 7 to rotate. This action causes the first moving plates 8 on both sides to move inward or outward synchronously. As the first moving plates 8 shift, the position of the cutter bodies 13 on the two rollers 12 is adjusted, thereby achieving precise cutting of the cable. Simultaneously, the rotation of the first bidirectional threaded rod 7 is transmitted to the second rotating shaft 15 via the transmission belt 14, causing it to rotate synchronously. This rotation further drives the second bidirectional threaded rod 18 to rotate through the meshing of the driving bevel gear 16 and the driven bevel gear 17. The rotation of the second bidirectional threaded rod 18 adjusts the position of the material distribution plates 20 on the two second moving plates 19, ensuring that the material distribution plates 20 can synchronously adapt to changes in cable size. This design greatly improves the ease of adjustment and practicality of the device. When changing the cutter bodies 13 on the rollers 12, pressing the button 24 pushes the connecting rods 23 on both sides inward, thereby causing the fixing block 21 to also move inward, thus releasing the locking state between the fixing block 21 and the fixing groove inside the connecting plate 9. In this way, the fixed relationship between the connecting plate 9 and the cutter holder 10 is released, making it easier to replace the cutter. When installing the cutter, simply place the cutter holder 10 in the appropriate position, and using the elastic force of the spring 22, the fixing blocks 21 on both sides will move outward and realign with the fixing groove, thereby re-fixing the connecting plate 9 and the cutter holder 10, facilitating the installation of the cutter.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
