[0002] Wires and cables are wire products used to transmit electrical 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 insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors, and the surface of the cable will be coated with insulating materials to achieve insulation effects. Usually, a coating device is used to coat the cable with refractory materials.

[0003] The copper wire is affected by its own stress. When it is unrolled from the copper wire coil, the copper wire will be slightly bent. When the coating device wraps the hot-melt plastic mud around the copper wire, the bent copper wire will not be in the center of the wire, resulting in uneven thickness of the wire sheath.

During this process, the slider plate will slide outward along the inner wall of the slide groove, and the spring will force the obstruction slide plate to contact the inner wall of the obstruction tooth block, and the arc surface of the obstruction tooth block contacts the arc surface of the obstruction slider, and the obstruction tooth block will provide a large resistance to the movement of the slider plate. At this time, when the electric telescopic rod drives the control block to move outward, the bottom mounting frame is blocked and difficult to move, and the control block will move outward along the outer wall of the mounting frame, causing the ball bearing to roll along the inclined surface of the inclined surface one, and the rolling ball bearing drives the sliding column and the clamping frame to move toward the center, so that the clamping frames at both ends are moved from Figure 4 The status changes to Figure 6 In the state, the cross clamping frame will apply a clamping force to the copper wire, and when the control block moves to the outermost edge of the mounting frame, the control block will drive the mounting frame to move outward along an inner wall of the slide groove. Through the application of the above components, after the clamping frame clamps the copper wire, the displaced mounting frame will straighten the copper wire, thereby eliminating most of the residual stress in the copper wire and reducing the degree of bending of the copper wire before entering the coating box.

At this time, the rolling plate drives the arc surface to contact the outer wall of the roller, and the roller will force the L-shaped rod to slide downward along the inner wall of the second slide groove, and the downward L-shaped rod will be inserted into the gap between the copper wire groups. When the L-shaped rod slides down to the lowest position, the rotating force of the rolling plate will drive the inner ring to rotate synchronously through the L-shaped rod, and the rotating L-shaped rod will force multiple copper wires to rotate and twist together.

When the electric telescopic rod 21 extends outward, the gear 47 will rotate along the outer wall of the gear rod 48 and force the rolling plate 44 to rotate counterclockwise. At this time, the arc surface 53 loses the restriction on the roller 55, and then the spring three 56 releases the mechanical power, forcing the L-shaped rod 54 to reset and shrink, so that the L-shaped rod 54 is away from the copper wire. Through the application of the above components, it is avoided that the driving mechanism 2 and the processing mechanism 3 will not continue to twist when the copper wire is in a tight state when straightening the copper wire, causing the copper wire to be subjected to excessive pressure and causing damage to the copper wire.
