Description

Technical Field

[0001] The utility model relates to the technical field of wrapping machine structures, in particular to a tension control device for a high-speed wrapping machine of a fire-resistant mica tape. Background Art

[0002] Taping machines, available in single, double, or triple layer configurations, wrap tape (mica tape, cotton paper tape, aluminum foil, polyester film, etc.) around the core wire via a rotating turntable. They are primarily used for wrapping the insulated core wires of electrical wires, power cables, control cables, and optical cables. For example, these machines include high-speed concentric steel tape armor wrapping machines.

[0003] During operation of the existing taping machine, the tension of the refractory mica tape is fixed, which results in the mica tape being easily torn or the cable being bent during the speed change of the taping machine.

[0004] Therefore, we propose a tension control device for a high-speed wrapping machine of refractory mica tape to solve the existing problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the background technology and to provide a tension control device for a high-speed wrapping machine of a refractory mica tape.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a tension control device for a high-speed wrapping machine of refractory mica tape, comprising a crossbeam, a turntable, a cable, a machine body, a slider and a screw, wherein a shaft is rotatably mounted on the machine body, a turntable is fixed to one end of the shaft, a crossbeam is fixed to the turntable by bolts, a slider is slidably provided on the crossbeam, the slider passes through the belt body, and one end of the belt body is wrapped around the cable.

[0007] Preferably, a mounting hole adapted to the shaft is provided on the machine body, and the shaft is rotatably mounted on the mounting hole.

[0008] Preferably, the crossbeam, the turntable and the shaft rod are all provided with through-holes adapted to the cables, the through-holes of the three are located on the same central axis, and the cables are movably connected to the through-holes.

[0009] Preferably, a square hole is provided on the slider, and the belt body moves through the square hole.

[0010] Preferably, a screw is rotatably mounted on the crossbeam, a screw hole adapted to the screw is provided on the slider, the screw thread is provided on the screw hole, and the rear surface of the slider is in sliding contact with the outer wall of the crossbeam.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. During use of the tension control device of the high-speed wrapping machine for refractory mica tape of the present invention, the turntable rotates to wrap the refractory mica tape body around the cable. During this process, the screw can be rotated as needed. When the control slider approaches the cable, the triangular area formed by the tape body, cable, and crossbeam becomes smaller. At this time, the tension of the tape body becomes larger. When the control slider moves away from the cable, the triangular area formed by the tape body, cable, and crossbeam becomes larger. At this time, the tension of the tape body becomes smaller. The utility model can adjust the tension of the refractory mica tape winding in real time according to the use needs of the personnel to prevent the tape body and the cable from being pulled by excessive external force.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] like Figure 1-3 As shown, the tension control device of the high-speed wrapping machine of refractory mica tape proposed by the present invention includes a beam 1, a turntable 2, a cable 4, a body 5, a slider 7 and a screw 9. A shaft 3 is rotatably mounted on the body 5, and a turntable 2 is fixed at one end of the shaft 3. The turntable 2 is fixed to the beam 1 by bolts. A slider 7 is slidably provided on the beam 1, and the slider 7 passes through the belt body 6. One end of the belt body 6 is wound around the cable 4.

[0020] Based on Example 1: the turntable 2 rotates to wrap the refractory mica tape 6 around the cable 4. During this process, the screw 9 can be rotated as needed. When the control slider 7 approaches the cable 4, the triangular area formed by the tape 6, the cable 4, and the crossbeam 1 becomes smaller. At this time, the tension of the tape 6 becomes greater. When the control slider 7 moves away from the cable 4, the triangular area formed by the tape 6, the cable 4, and the crossbeam 1 becomes larger. At this time, the tension of the tape 6 becomes smaller.

[0021] Example 2

[0022] like Figure 1-3 As shown, the tension control device of the high-speed wrapping machine of refractory mica tape proposed by the utility model, compared with the first embodiment, this embodiment also includes: a mounting hole adapted to the shaft rod 3 is opened on the machine body 5, and the shaft rod 3 is rotatably mounted on the mounting hole. The design of the mounting hole facilitates the positioning of the installation position of the shaft rod 3.

The through-holes 10 of the three are on the same central axis, and the cables 4 are movably connected to the through-holes 10. The design of the through-holes 10 facilitates the connection of the cables 4, so that the cables 4 can pass through the turntable 2 at a uniform speed for wrapping operations under the pull of external power.

[0024] A square hole 8 is provided on the slider 7 , and the belt body 6 moves through the square hole 8 . The design of the square hole 8 allows the slider 7 to limit the position of the belt body 6 .
