Description

Technical Field

[0001] The utility model relates to the technical field of flame-retardant wrapping tapes, in particular to a wrapping tape for low-smoke, halogen-free and highly flame-retardant cables. Background Art

[0002] Cable is an electrical device composed of conductors and insulating materials, mainly used for power transmission and signal transmission. Cable is usually composed of multiple conductors, which can be a single conductor or multiple conductors bundled together. The insulation layer is used to protect the conductors and prevent leakage and short circuit. Depending on the application and requirements, cables have various types and specifications.

[0003] Wrapping tape (also known as wrapping material, wrapping film or winding tape) is a material used to wrap and protect cables. It is usually used for the insulation layer and mechanical protection of cables. Cable wrapping tape is an important material for cable manufacturing and protection. It is mainly used to wrap cable conductors or coils to improve their mechanical strength, provide insulation and prevent damage caused by the external environment.

[0004] At present, in the cable wrapping process, a wrapping tape made of a single type of insulating and wear-resistant material is usually used, and manual wrapping is often adopted. After the wrapping is completed, it is cut with the help of auxiliary tools. This operation method not only reduces the safety of the wrapping tape, but also reduces the wrapping efficiency. Therefore, we propose a low-smoke, halogen-free, and highly flame-retardant cable wrapping tape. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figures 1-6 As shown, in this embodiment, a wrapping tape for low-smoke halogen-free and highly flame-retardant cables includes a wrapping tape body 1, which is composed of an insulating layer 2, a wear-resistant layer 3 and a flame-retardant layer 4. The inner walls of the insulating layer 2 are fixedly connected to the wear-resistant layer 3, and the inner walls of the wear-resistant layer 3 are fixedly connected with the flame-retardant layer 4. A rotating drum 8 is fixedly connected between the inner walls of the wrapping tape body 1, and both ends of the rotating drum 8 are rotatably connected to fixed plates 5. The two fixed plates 5 are respectively rotatably connected to the two sides of the wrapping tape body 1, and a guide block 6 is fixedly connected between the outer sides of the two fixed plates 5. A cutting assembly is provided on the top of the guide block 6, and a guide groove 14 is opened on one side of the guide block 6. The guide groove 14 passes through the guide block 6, and the outer side of the wrapping tape body 1 is slidably connected between the inner walls of the guide groove 14.

[0024] When wrapping the cable with the wrapping tape, the wrapping tape body 1 is first formed by the insulating layer 2, the wear-resistant layer 3 and the flame-retardant layer 4, so that the cable is safely protected. Then the operator manually pulls one end of the wrapping tape body 1, so that the outer side of the wrapping tape body 1 slides between the inner walls of the guide groove 14, so that the rotating drum 8 connected to the inner side of the wrapping tape body 1 rotates between the two fixed plates 5, so that the operator can quickly wrap the cable. After the wrapping is completed, the wrapping tape body 1 is cut off by the cutting assembly, so that the entire wrapping work is completed smoothly, thereby improving the safety of the wrapping tape and the efficiency of the wrapping work.

[0025] like Figures 1-6As shown, the cutting assembly includes a slide groove 12, a lower pressure block 16 is slidably connected between the inner walls of the slide groove 12, a spring 13 is fixedly connected between the lower pressure block 16 and the inner wall of the slide groove 12, a pressing block 7 is slidably connected above the guide block 6, the inner side of the pressing block 7 is fixedly connected to the top of the lower pressure block 16, guide grooves 15 are provided on both sides of the guide block 6, guide blocks 10 are fixedly connected on both sides of the pressing block 7, one side of the two guide blocks 10 slides between the inner walls of the two guide grooves 15 respectively, a cutter 11 is fixedly connected to one side of the pressing block 7, and a connecting block 9 is fixedly connected to one side of the guide block 6. A cutting groove 17 is provided on the top of the connecting block 9, and the outer side of the cutter 11 contacts the inner side of the cutting groove 17.

[0026] By manually pressing the button 7, the pressing block 16 applies pressure to the spring 13 inside the slide groove 12, and then the two guide blocks 10 slide between the inner walls of the two guide grooves 15 respectively, thereby driving the cutter 11 to move on one side of the guide block 6. Through the action of the connecting block 9, the outer side of the cutter 11 contacts the inner side of the cutting groove 17, thereby cutting the wrapping tape, thereby improving the convenience and efficiency of wrapping the wrapping tape.

[0027] The utility model provides a wrapping tape for low-smoke, halogen-free and highly flame-retardant cables. The specific working principle is as follows: when the wrapping tape is wrapped around the cable, the wrapping tape body 1 is first formed by the insulating layer 2, the wear-resistant layer 3 and the flame-retardant layer 4, so that the cable is safely protected. Then, the operator manually pulls one end of the wrapping tape body 1 so that the outer side of the wrapping tape body 1 slides between the inner walls of the tape guide groove 14, so that the rotating drum 8 connected to the inner side of the wrapping tape body 1 rotates between the two fixed plates 5, so that the operator can wrap the cable quickly. After the wrapping is completed, the pressing block 7 is manually pressed down so that the pressing block 16 applies pressure to the spring 13 inside the slide groove 12, and then the two guide blocks 10 slide between the inner walls of the two guide grooves 15 respectively, thereby driving the cutter 11 to move on one side of the tape guide block 6. Through the action of the connecting block 9, the outer side of the cutter 11 contacts the inner side of the cutting groove 17, thereby cutting the wrapping tape body 1, so that the entire wrapping work is completed smoothly.
