Description
Technical Field
[0001] The utility model relates to the technical field of cable processing, in particular to a cutting device for fireproof cables. Background Art
[0002] At present, the most widely used fire-resistant cables are mainly UL series flame-retardant cables and flame-retardant low-smoke halogen-free cables. Flame-retardant cables mainly rely on filling materials inside the cables that can provide good flame-retardant properties. Commonly used flame-retardant cable filler materials include mineral fillers, polystyrene foam, silicone fillers, etc. Among them, mineral fillers are one of the most commonly used materials in flame-retardant cable fillers. Mineral fillers are usually a mixture of high-temperature quartz sand, alumina, magnesium oxide and other substances, and have good high temperature resistance and flame retardant properties.
[0003] After searching, the existing Chinese patent announcement number is: CN220387765U, which provides a fire-proof cable cutting device. The patent drives the guide wheel to rotate through an external driving device. Since the arc-shaped opening on the outer surface of the guide wheel fits with the outer surface of the cable body, the cable body can be pressed when the guide wheel rotates, making the cable body straight while conveying the cable body.
[0004] Although the above patent can transport the cable in a straight line, the above scheme still has the following problems: since the fillers in the fireproof cable are mostly mineral fillers, when the fireproof cable is cut and truncated, the cutting knife will cut the mineral fillers in the fireproof cable. Since the mineral fillers will produce large flying dust when cutting, and since the device is not shielded when cutting the fireproof cable, the large flying dust will cause harm to the health of the surrounding workers.
[0005] In view of the above problems, a fireproof cable cutting device is proposed. Utility Model Content

[0033] Combination Figure 2 and Figure 3 , second pressure plates 19 are fixedly connected to both sides of the inner wall of the protection box 1 for placing the fireproof cable body 2, and a lifting plate 7 is slidably connected to the inner wall of the protection box 1, and two first pressure plates 9 are fixedly connected to the bottom of the lifting plate 7, and the two first pressure plates 9 and the two second pressure plates 19 are all arc-shaped, so that the first pressure plates 9 and the second pressure plates 19 can better fit with the surface of the fireproof cable body 2, thereby ensuring the fixing effect of the device on the fireproof cable body 2.
[0034] The surfaces of the two first pressure plates 9 and the two second pressure plates 19 are fixedly connected with anti-slip pads 10. The provision of the anti-slip pads 10 increases the friction between the surface of the fireproof cable body 2 and the first pressure plates 9 and the second pressure plates 19, thereby avoiding the fireproof cable body 2 from shifting in the protective box 1 when the device cuts and truncates the fireproof cable body 2, thereby ensuring the fixing effect of the device on the fireproof cable body 2.
[0035] The surface of the protection box 1 is threadedly connected with a threaded rod 3 that penetrates the surface of the protection box 1. The lower end of the threaded rod 3 is rotatably connected to the surface of the lifting plate 7. Through the setting of the threaded rod 3, the staff can drive the lifting plate 7 to slide and descend in the protection box 1 by rotating the threaded rod 3, thereby clamping and fixing the fire-proof cable body 2. The surface of the lifting plate 7 is fixedly connected with a telescopic rod 8, and the upper end of the telescopic rod 8 is fixedly connected to the inner wall of the protection box 1 to guide the sliding of the lifting plate 7.
[0036] The telescopic rod 8 includes a telescopic inner rod and a telescopic outer sleeve. The telescopic inner rod and the telescopic outer sleeve slide with each other, so that the length of the telescopic rod 8 can be changed, thereby ensuring the smooth operation of the device.
[0037] Furthermore, an electric push rod 17 is fixedly connected to the inner wall of the protection box 1, and a power box 12 is fixedly connected to the lower end of the electric push rod 17. A motor is arranged inside the power box 12 to provide power for the operation of the device.

[0039] The upper end of the nozzle 13 is fixedly connected to the lower end of the bellows 14. Through the setting of the bellows 14, when the lifting plate 7 is lifted up and down in the protective box 1, the bellows 14 can be correspondingly extended and retracted with the lifting of the lifting plate 7, thereby ensuring the mutual connection between the nozzle 13 and the drain pipe 15 and ensuring the smooth flow of water.
[0040] Combination Figure 4 A pull rod 16 is fixedly connected to the surface of the power box 12, and the pull rod 16 passes through the surface of the protective box 1 and is slidably connected to the inside of the protective box 1.

[0041] Specifically, when cutting the fireproof cable body 2, the fireproof cable body 2 is passed through the protection box 1, and then the threaded rod 3 is rotated, thereby driving the lifting plate 7 to slide down in the protection box 1, and driving the two first pressure plates 9 to descend, and gradually fit with the second pressure plate 19, so as to fix the fireproof cable body 2, and then the staff can start the electric push rod 17 and the power box 12, thereby driving the cutting knife 11 to descend and rotate at the same time, as the power box 12 and the cutting knife 11 descend, the cutting knife 11 cuts and cuts the fireproof cable body 2, and at the same time, the power box 12 descends, pulling the pull rod 16, thereby driving the partition plate 6 to slide down in the water tank 4, thereby gradually reducing the space below the water tank 4, so that the partition plate 6 squeezes the water at the bottom of the water tank 4, so that the pressure in the space below the water tank 4 gradually increases, and the pressure acts on the drain pipe 1 5 is squeezed, so that the one-way valve 20 in the drain pipe 15 is opened, so that the water flow can flow in the drain pipe 15 and flow out through the nozzle 13 to spray the cutting knife 11, thereby realizing the cooling of the cutting knife 11, avoiding the cutting knife 11 working for a long time, the temperature of the cutting knife 11 is high, thereby reducing the service life of the cutting knife 11, and at the same time, the cutting knife 11 and the fireproof cable body 2 can be soaked, thereby avoiding the situation that when the cutting knife 11 cuts the fireproof cable body 2, the filler inside the fireproof cable body 2 is cut by the cutting knife 11, and a large amount of flying dust is generated, thereby reducing the pollution caused to the outside world when the fireproof cable body 2 is cut, reducing the damage caused to the staff when the fireproof cable body 2 is cut, thereby improving the use effect of the device, and having high promotion value and practicality.
[0042] Working principle: Start the electric push rod 17 and the power box 12, drive the cutting knife 11 to descend and rotate at the same time, and then the cutting knife 11 cuts and cuts the fireproof cable body 2. At the same time, the descent of the power box 12 pulls the pull rod 16, driving the partition plate 6 to slide and descend in the water tank 4, so that the partition plate 6 squeezes the water at the bottom of the water tank 4, so that the pressure in the space below the water tank 4 gradually increases, and then squeezes the one-way valve 20 in the drain pipe 15, so that the one-way valve 20 in the drain pipe 15 opens, so that the water can flow in the drain pipe 15 and flow out through the nozzle 13 to spray the cutting knife 11.
