Description

Technical Field

[0001] The utility model belongs to the technical field of cable production equipment, in particular to a fire-resistant mica tape wrapping device. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulating cores, and their respective coatings, total protective layers and outer sheaths. The coating of the cable core is usually made by winding the mica tape evenly on the surface of the cable core through a winding device. However, most of the winding devices currently used on cables have poor applicability, and during the winding process, the cable core cannot be effectively limited, resulting in the cable core being prone to shaking during the winding process, affecting the winding effect, and there are certain defects.

[0003] A cable fire-resistant mica tape wrapping device with publication number CN211555599U can effectively limit the cable core during the wrapping process through the setting of the wire pressing assembly, effectively reduce the frequency of cable core shaking during the wrapping process, and improve the cable wrapping effect. At the same time, the utility model has strong applicability and can realize the wrapping of mica tapes of different thicknesses for cable cores of different diameters, which is highly practical. However, it still needs to be manually pre-wound at the front end before the machine can be started for automatic wrapping, which is not conducive to continuous processing. Utility Model Content

[0006] In a further embodiment, the harness plate is provided with a plurality of provisions, and a hole adapted to the cable is provided at the center of the harness plate.

[0007] In a further embodiment, the cavity of the square shell is provided with two symmetrical movable plates, and two side plates are connected to adjacent sides of the two movable plates.

[0012] In a further embodiment, a driving motor is installed on one side of the circular shell, and a driving end of the driving motor passes through the circular shell and is connected to the center of the driving gear.

[0013] In a further embodiment, a threading hole is opened in the center of the round shell, and support rods are connected between the bottom ends of the wiring harness plate, the round shell and the square shell and the bottom plate.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The embedded design of the ring gear and the round shell and the fixed position of the card cover limit the ring gear. Through the meshing design of the driving gear and the inner ring of the ring gear and the connection design of the driving motor and the center of the driving gear, combined with the connection between the winder and the ring gear, when the driving motor is running, it can drive the winder outside the ring gear to rotate, so as to realize automatic wrapping.

The symmetrical design of the two moving plates and the pressure wheel design on the adjacent side of the moving plate, and the connection design between the pressure wheel and the side plate through a one-way bearing, make the cable only move outward in one direction, and will not slide inward, causing the mica tape to be pressed and loosened;

[0017] The thread connection design of the bidirectional screws at both ends of the moving plate and the design that the threads at both ends of the bidirectional screws are in opposite directions, combined with the connection design of the rotating motor and the bidirectional screw, when the rotating motor is running, it can drive the two moving plates to move, so that the two pressing wheels drive the mica tape and the cable to be pressed and fixed, so as to adapt to cables of different diameters;

[0018] The refractory mica tape wrapping device can not only automatically press the mica tape to reduce the manual winding process in the initial stage, but also has an automatic wrapping effect, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
