Description

Technical Field

[0001] This utility model relates to the field of security cabling cutting technology, and specifically discloses a cutting device for security cabling. Background Technology

[0002] During the construction of security engineering projects, it is necessary to plan, lay and manage the cables required by each subsystem of the security system in a unified manner. When carrying out security cabling construction, the cables need to be cut and processed using cutting equipment according to the different lengths used.

[0003] Chinese patent CN218015466U discloses a wire cutting device, including a base, a cutting frame fixed in the middle of the base, symmetrical hydraulic push rods fixed on the cutting frame, and a cutting blade fixed at the movable end of each hydraulic push rod. A set of positioning brackets is fixed on each side of the base. This wire cutting device, by passing the wire sequentially through a placement slot and placing it on the symmetrical positioning brackets, facilitates the control of the positioning seats moving downwards along the support rod. In conjunction with L-shaped and N-shaped connecting rods, three sets of gourd-shaped connecting blocks are pushed to contact the top of the clamping component, causing the clamping component to move downwards and fix both ends of the wire in the clamping groove. The hydraulic push rods drive the cutting blades downwards, facilitating the cutting of the positioned wire. This solves the problems of low efficiency and the tendency for the wire to move during the cutting process, which hinders precise cutting.

[0004] This technical solution requires manual handling of cables and measurement of the cable length to be cut during application, which presents technical problems such as the inability to continuously and efficiently transport cables and the inability to simultaneously measure the cable length required for cabling. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a cutting device for security wiring to solve the problems of existing wire cutting devices requiring manual handling of cables and measurement of the length of cables to be cut, which cannot continuously and efficiently transport cables and cannot simultaneously measure the length of cables to be cut during wiring construction.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] The aforementioned security wiring cutting device includes a base. A frame and a groove are fixedly arranged at intervals on the upper surface of the base.

[0011] Furthermore, stabilizing rods are fixedly installed at both ends of the inner side of the frame, and the stabilizing rods are fixedly connected to the top and bottom ends of the inner side of the frame.

[0012] Furthermore, both ends of the tool holder are fixedly provided with stabilizing sleeves in conjunction with stabilizing rods. The stabilizing sleeves are sleeved on the outer surface of the stabilizing rods and can slide up and down along the outer surface of the stabilizing rods.

[0025] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-4As shown, the security wiring cutting device includes a base 1. A frame 2 and a groove 3 are fixedly arranged at intervals on the upper surface of the base 1. A cylinder 8 is fixedly arranged through the middle of the top of the frame 2. A connecting plate 20 is fixedly arranged at the bottom of the cylinder 8. A blade holder 17 is fixedly arranged at the bottom of the connecting plate 20. A cutting blade 15 is fixedly arranged at the bottom of the blade holder 17. The groove 3 is U-shaped. A conveying roller 7 and a linkage roller 11 are rotatably arranged from top to bottom on the inner side of the groove 3. Rubber pads 6 are sleeved on the outer surfaces of the conveying roller 7 and the linkage roller 11. A drive motor 12 is fixedly arranged on the top of the outer wall of the groove 3 in conjunction with the conveying roller 7. A speedometer 4 is fixedly arranged on the top of the inner wall of the groove 3 away from the drive motor 12. A stabilizing component is also arranged at the bottom of the connecting plate 20. The stabilizing component and the blade holder 17 are spaced apart.

[0028] The end of the conveying roller 7 near the drive motor 12 passes through the trough 3 and is fixedly connected to the output end of the drive motor 12.

[0029] The conveying roller 7 and the linkage roller 11 are arranged in parallel and spaced apart, and a shearing table 9 is fixedly installed at the bottom of the inner side of the frame 2.

[0030] Positioning cylinders 5 are fixedly installed in the middle of both sides of the upper end face of the base 1, and the two positioning cylinders 5 are at the same height. The height of the two positioning cylinders 5 is adapted to the height of the upper end face of the shearing table 9 and the height of the gap between the conveying roller 7 and the linkage roller 11.

[0031] Stabilizing rods 10 are fixedly installed at both ends of the inner side of the frame 2, and the stabilizing rods 10 are fixedly connected to the top and bottom ends of the inner side of the frame 2.

[0032] Both ends of the tool holder 17 are fixedly provided with stabilizing sleeves 16 in conjunction with the stabilizing rod 10. The stabilizing sleeves 16 are sleeved on the outer surface of the stabilizing rod 10 and can slide up and down along the outer surface of the stabilizing rod 10.

[0033] With the above setup, the positioning cylinder 5 positions the cables of the input and output devices, ensuring the stability of the entire working process. After the cable is conveyed to the upper surface of the shearing table 9 and fixed to a certain length, the cylinder 8 is activated to push the cutter holder 17 and the shearing cutter 15 downward to cut the cable. When the cutter holder 17 descends, the stabilizing sleeve 16 slides downward on the outer surface of the stabilizing rod 10 to limit and stabilize the cutter holder 17 and the shearing cutter 15. The drive motor 12 drives the conveying roller 7 to rotate, and the linkage roller 11 is used to transmit the cable that passes between them. The rotation of the conveying roller 7 and the linkage roller 11 are opposite. The rubber pad 6 ensures the continuity of cable conveying. The number of rotations of the conveying roller 7 is measured by the speedometer 4, thereby determining the length of the conveyed cable. There is no need to manually measure the cable length and then compare it before cutting, which improves the efficiency of cable cutting in security wiring construction, reduces manual operation, and lowers costs.

[0034] The stabilizing component includes a through hole 21 that is opened through the middle of the connecting plate 20. A movable rod 18 is slidably disposed through the through hole 21. The top end of the movable rod 18 is slidably disposed in the cylinder 8. A pressure plate 19 is fixedly disposed at the bottom end of the movable rod 18. A protective pad 14 is fixedly disposed at the bottom end of the pressure plate 19.

[0035] A compression spring 13 is sleeved on the outer surface of the movable rod 18, and the compression spring 13 is disposed between the connecting plate 20 and the pressure plate 19.

[0036] The top end of the compression spring 13 is fixedly connected to the bottom end of the connecting plate 20, and the bottom end of the compression spring 13 is fixedly connected to the top end of the pressure plate 19.

[0037] The height of the bottom of the protective pad 14 is lower than the height of the bottom of the shearing blade 15.

[0038] With the above setup, because the height of the bottom of the protective pad 14 is lower than the height of the bottom of the shearing blade 15, when the connecting plate 20 is driven down by the cylinder 8, the pressure plate 19 is pushed by the compression spring 13 to contact the cable first and press and stabilize the cable before the shearing blade 15 contacts the cable and performs shearing. When the compression spring 13 is compressed, the movable rod 18 supports and stabilizes the compression spring 13 in the through hole 21, preventing the pressure plate 19 from tilting due to the bending of the compression spring 13. By fixing the protective pad 14 at the bottom of the pressure plate 19, the cable sheath is protected by the protective pad 14, so that the cable can be pressed and stabilized safely and stably during the shearing process, ensuring the accuracy of the shearing.

[0039] Working principle and process:

[0040] When using the shearing equipment, the cable to be cut is first threaded through the positioning cylinder 5 on one side and through the upper end face of the shearing table 9. It then passes through the gap between the conveying roller 7 and the linkage roller 11, and exits through the positioning cylinder 5 on the other side. The conveying roller 7 is then driven to rotate, and the cable is conveyed through the linkage roller 11. Rubber pads 6 prevent slippage between the cable and the conveying roller 7 and linkage roller 11. During cable conveying, a speedometer 4 is used to measure the number of rotations of the conveying roller 7, thereby determining the length of the conveyed cable. Once the desired cable length is reached, the drive motor 12 stops. The machine operates by starting cylinder 8 to push connecting plate 20 downward. During the downward movement of connecting plate 20, pressure plate 19 is first pressed and stabilized by spring 13. Then, cutting tool 15 contacts the cable and cuts it. At the same time, moving rod 18 supports and stabilizes spring 13, and protective pad 14 protects the cable sheath. During the descent of connecting plate 20, stabilizing sleeve 16 slides downward on the outer surface of stabilizing rod 10 to limit and stabilize tool holder 17 and cutting tool 15, thereby performing efficient, stable and precise fixed-length cutting of security cables.
