[0002] Wires and cables are a type of wire product used to transmit electrical energy (electromagnetic), information and realize electromagnetic energy conversion. During the production process of wires and cables, a longitudinal wrapping machine is required to wrap a layer of aluminum-plastic tape on the surface of the semi-finished wires and cables to improve the performance of the wires and cables.

[0003] In the existing longitudinal wrapping machine for wires and cables, when the aluminum-plastic tape passes through the shaping mold and is wrapped around the semi-finished wires and cables, aluminum shavings will be generated due to friction between the aluminum-plastic tape and the shaping mold. When these aluminum shavings enter between the aluminum-plastic tape and the semi-finished wires and cables, they will affect the fit between the two and cause the aluminum-plastic tape to wrinkle and bulge. For this reason, we propose a longitudinal wrapping machine for wires and cables. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1: Figures 1 to 4 As shown, the utility model proposes a longitudinal wrapping machine for wires and cables, comprising a semi-finished wire and cable 1, an aluminum-plastic tape 2 and a machine base 10, a U-shaped tube 3 is installed on one side of the upper surface of the machine base 10, a notch is provided on the upper surface of the U-shaped tube 3, a reducer 5 is installed at the end of the U-shaped tube 3, the aluminum-plastic tape 2 passes through the U-shaped tube 3 and the reducer 5 and is wrapped around the outer surface of the semi-finished wire and cable 1, a shaping tube 8 is installed at the end of the reducer 5, a groove 7 is provided on the upper surface of the machine base 10 below the shaping tube 8, a heating ring 6 is sleeved on the outer surface of the shaping tube 8, and the heating ring 6 is located inside the groove 7, a fan 11 is installed on one side of the inside of the machine base 10, an air outlet 14 is installed at the output end of the fan 11, and the air outlet 14 is installed at the output end of the air outlet 14. A nozzle 15 is installed at the end of the U-shaped tube 3 and is located above the U-shaped tube 3 and close to the reducer 5. A filter box 12 is installed inside the base 10 near the outer side of the fan 11. The input end of the fan 11 is connected to the inner side of the filter box 12. An exhaust pipe 13 is installed on the upper surface of the filter box 12. A wind cover 16 is installed at the end of the exhaust pipe 13. The wind cover 16 is located above the U-shaped tube 3 and away from the side of the nozzle 15. A filter screen 18 is installed inside the filter box 12.

Support legs 9 are installed near the four corners of the lower surface of the base 10.

[0020] The working principle of a longitudinal wrapping machine for wires and cables based on Example 1 is as follows: when the aluminum-plastic tape 2 passes through the U-shaped tube 3, the tape is gradually changed into a U-shaped ring, and the aluminum chips generated by the friction between the aluminum-plastic tape 2 and the U-shaped tube 3 are blown away by the high-pressure gas blown out by the air nozzle 15. At the same time, the gas inside the filter box 12 enters the fan 11 to reduce the air pressure inside the filter box 12, and the raised aluminum chips are sucked into the filter box 12 by the wind hood 16 and filtered out by the filter screen 18. When the U-shaped aluminum-plastic tape 2 enters the reducer 5, it changes from a U-shaped ring to a ring and is wrapped around the semi-finished wires and cables 1. The semi-finished wires and cables 1 wrapped with the aluminum-plastic tape 2 enter the shaping tube 8 and are heated by the heating ring 6 so that the aluminum-plastic tape 2 adheres to the outer surface of the semi-finished wires and cables 1.

[0021] Embodiment 2: Figure 1 and Figure 4 As shown, the utility model proposes a longitudinal wrapping machine for electric wires and cables. Compared with the first embodiment, this embodiment also includes a sealing plate 20 installed on the outside of the filter box 12, a pull block 19 installed on the outside of the sealing plate 20, a protrusion 21 installed on the inside of the sealing plate 20, a card slot 17 is provided on one side of the filter box 12 close to the sealing plate 20, a rubber clip 22 is installed on the outer surface of the protrusion 21, and the rubber clip 22 is located inside the card slot 17.

[0022] In this embodiment, when it is necessary to clean the filter screen 18 and the inside of the filter box 12, the sealing plate 20 is pulled by the pull block 19, and the rubber clip 22 on the outer surface of the protrusion 21 and the card groove 17 on the inner wall of the filter box 12 are separated, and the sealing plate 20 can be removed, so that the inside of the filter box 12 and the filter screen 18 can be cleaned.
