Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and more specifically, to a cutting device for cable production. Background Technology

[0002] Cable cutting equipment is used to cut cables, wires, or other types of conductors to the required lengths. These devices typically play an important role in cable production lines, enabling precise cutting of different types and specifications of cables for subsequent packaging, splicing, or other processing steps.

[0003] In the prior art, such as the "Cable Cutting Device" in Chinese Patent Publication No. CN220532853U, the device does not require manual fixing of the cable or operation of the circular saw during the cable cutting process, thus ensuring the safety of the operation.

[0004] However, during the use of the above device, if a second cutting operation is required after the cable has been cut, the operator needs to remove the cable from the clamping mechanism and adjust it to the appropriate length before placing it back into the clamping mechanism for the second cutting operation. This process requires the operator to spend a lot of time disassembling and assembling the positioning cable, which is very inconvenient and reduces the efficiency of the device in continuous cutting operations. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for cable production, which solves the problem that existing devices require reassembly and repositioning of cables when performing secondary cutting, thus reducing the efficiency of continuous cutting operations.

[0006] To achieve the above objectives, a cutting device for cable production is provided, including a workbench, a fixed frame fixedly connected to the top surface of the workbench, a frame fixedly connected to the top surface of the workbench, a positioning plate fixedly connected inside the frame, and a cable clamping mechanism provided inside the fixed frame for clamping the cable to be cut. The cable clamping mechanism includes a motor fixedly connected to one side of the fixed frame and a bidirectional lead screw rotatably connected inside the fixed frame. The external threads of the bidirectional lead screw are connected to two symmetrically arranged movable plates, both of which are slidably connected inside the fixed frame, and two pulleys are rotatably connected to opposite sides of the two movable plates.

[0007] The frame is equipped with a cable positioning mechanism, which is used to position the cable to be cut.

[0008] As a further improvement to this technical solution, one end of the bidirectional lead screw passes through one side of the inner wall of the fixed frame and is connected to the output end of the motor for transmission, and the other end of the bidirectional lead screw passes through the other side of the inner wall of the fixed frame and is fixedly connected to a first bevel gear.

[0009] As a further improvement to this technical solution, the cable positioning mechanism includes a lifting plate slidably connected inside the frame and fixed wheels fixedly connected to the top surface of the workbench, with the lifting wheels rotatably connected to the bottom of the lifting plate.

[0010] As a further improvement to this technical solution, one end of the lifting plate penetrates through one side of the inner wall of the frame and is threadedly connected to a connecting screw. The bottom of the connecting screw is rotatably connected to the top surface of the worktable, and a second bevel gear is fixedly connected to the outside of the connecting screw.

[0011] As a further improvement to this technical solution, a rotating rod is rotatably connected to the top surface of the worktable, and both ends of the rotating rod are fixedly connected to transmission bevel gears.

[0012] As a further improvement to this technical solution, one of the transmission bevel gears meshes with a first bevel gear, and the other transmission bevel gear meshes with a second bevel gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this cable production cutting device, a cable clamping mechanism and a cable positioning mechanism are set up. Four pulleys, fixed wheels and lifting wheels are used to clamp and position the cable. While the cable is limited, it can still move in a directional manner by cooperating with the rotation of the pulleys, fixed wheels and lifting wheels. In this way, if a secondary cutting operation is required after the device has cut the cable, the operator can directly pull the cable through the positioning plate and cut the cable directly after pulling it to a suitable length, saving the time of repositioning and clamping the cable and improving the working efficiency of the device.

[0015] 2. In this cable production cutting device, by setting a rotating rod with transmission bevel gears fixed at both ends, and utilizing the meshing transmission relationship between the two transmission bevel gears, the first bevel gear and the second bevel gear, it is possible to simultaneously realize the clamping and positioning of the cable by the lifting wheel and the fixed wheel while the motor starts to clamp and fix the cable on both sides, thereby improving the clamping and positioning efficiency of the device for the cable.

Detailed Implementation

[0022] 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.

[0023] Example: Please refer to Figure 1 - Figure 4 As shown, the purpose of this embodiment is to provide a cutting device for cable production, including a workbench 1, a fixed frame 2 fixedly connected to the top surface of the workbench 1, a frame 3 fixedly connected to the top surface of the workbench 1, a positioning plate 31 fixedly connected inside the frame 3, and a cable clamping mechanism 4 provided inside the fixed frame 2, which is used to clamp the cable to be cut. The cable clamping mechanism 4 includes a motor 41 fixedly connected to one side of the fixed frame 2 and a bidirectional lead screw 43 rotatably connected inside the fixed frame 2. The external threads of the bidirectional lead screw 43 are connected to two symmetrically arranged moving plates 42. Both moving plates 42 are slidably connected inside the fixed frame 2, and two pulleys 44 are rotatably connected to the opposite side of the two moving plates 42.

[0024] One end of the bidirectional lead screw 43 passes through one side of the inner wall of the fixed frame 2 and is connected to the output end of the motor 41. The other end of the bidirectional lead screw 43 passes through the other side of the inner wall of the fixed frame 2 and is fixedly connected to the first bevel gear 45.

[0025] In this embodiment, the frame 3 is equipped with a cable cutting mechanism, which is existing technology and will not be described in detail here. The positioning plate 31 has a through-hole, through which the cable can pass to enter the cutting mechanism for cutting. The motor 41 drives the bidirectional lead screw 43 to rotate, thereby controlling the two moving plates 42 to move closer or further apart within the fixed frame 2, thereby changing the distance between the two pulleys 44. This allows the pulleys 44 to clamp and release the cable. When the pulleys 44 clamp the cable, the cable can move in coordination with the pulleys 44. In this way, after the device cuts the cable, the operator can move the cable by pulling the end of the cable directly, without the need for secondary clamping and fixing of the cable, which improves the convenience of the device.

[0026] In addition, the frame 3 is equipped with a cable positioning mechanism 5, which is used to position the cable to be cut.

[0027] The cable positioning mechanism 5 includes a lifting plate 51 that is slidably connected inside the frame 3 and a fixed wheel 52 that is fixedly connected to the top surface of the workbench 1. The bottom of the lifting plate 51 is rotatably connected to the lifting wheel 53.

[0028] One end of the lifting plate 51 passes through one side of the inner wall of the frame 3 and is threadedly connected to a connecting screw 54. The bottom of the connecting screw 54 is rotatably connected to the top surface of the worktable 1, and a second bevel gear 55 is fixedly connected to the outside of the connecting screw 54.

[0029] A rotating rod 6 is rotatably connected to the top surface of the workbench 1, and both ends of the rotating rod 6 are fixedly connected to transmission bevel gears 61.

[0030] One of the transmission bevel gears 61 meshes with the first bevel gear 45, and the other transmission bevel gear 61 meshes with the second bevel gear 55.

[0031] In this embodiment, the spatial positions between the multiple pulleys 44 correspond to the spatial positions between the fixed wheel 52 and the lifting wheel 53, and also correspond to the positions of the positioning holes on the positioning plate 31. The cable positioning mechanism 5 is used to position the cable at the same height as the positioning holes on the positioning plate 31, and can also clamp the cable. In use, the lifting plate 51 drives the lifting wheel 53 to rise and fall, thereby controlling the lifting wheel 53 and the fixed wheel 52 to move closer or further apart, so that the lifting wheel 53 and the fixed wheel 52 can adapt to cables of different sizes and clamp and position the cable. When the motor 41 drives the bidirectional lead screw 43 to rotate, the first bevel gear 45 and its meshing transmission bevel gear 61 drive the rotating rod 6 to rotate, thereby driving the second bevel gear 55 to rotate at the other end of the rotating rod 6, achieving the effect of synchronously driving the connecting lead screw 54. In this way, when the cable clamping mechanism 4 clamps and fixes the cable, the cable positioning mechanism 5 can also clamp and position the cable synchronously, improving the clamping and positioning efficiency of the device for the cable.

[0032] The working principle of this device is as follows: First, the operator passes one end of the cable through the positioning hole on the positioning plate 31 and places the main body of the cable between multiple pulleys 44. At the same time, one end of the cable is placed on the fixed wheel 52. Then, the operator starts the motor 41 to drive the bidirectional lead screw 43 to rotate, thereby causing the moving plates 42 on both sides to drive the multiple pulleys 44 to move closer together until the cable is clamped and fixed. During this process, through the cooperation between the rotating rod 6 and the transmission bevel gears 61 at both ends, the connecting lead screw 54 can be driven to rotate synchronously. At this time, the lifting plate 51 descends, and the lifting wheel 53 clamps the end of the cable close to the positioning plate 31. Then, the operator can cut the cable through the cutting mechanism on the frame 3. After the cutting is completed, if the cable still needs to be cut again, the operator can directly pull the cable out through the positioning hole on the positioning plate 31. During this process, with the help of the pulleys 44, fixed wheel 52 and lifting wheel 53, the cable can move directly during the clamping process. After the operator pulls the cable out to a suitable length, the cutting operation can continue.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
