Problems solved by technology

However, at present, the wire stripping machine does not have the function of automatic wire separation. The peeled plastic wrapping layer and the metal core are still tightly connected together. It is necessary to use manual work to realize the complete separation of the two, which is troublesome to operate and low in efficiency.

Embodiment 1

[0024] figure 1 Shown is a wire stripping machine with different diameters of wire inlet holes installed, which can handle different wire diameters. figure 2 After the waste electric wires 2 of different diameters shown are inserted from the round hole 1 of the nearest hole diameter, they are moved forward under the action of the rotating cutting knife 3, and at the same time, the outer layer of the package is cut open, and the line is further along the arrow The direction shown enters between the two rotatable pressing rollers 4 that are arranged subsequently, and under the action of the pressing rollers, the cut wrapping outer layer 5 is separated from the metal core 6 and discharged (in figure 2 The figure only shows the status of waste electric wires before they enter, and the status of the cladding layer and metal core after separation. In actual operation, the cladding layer and copper core are a continuous process from the entrance to the exit, and the wires are also ...

Embodiment 2

[0026] exist Figure 4 A rotating pressure roller 11 with teeth is installed between the round hole and the cutting knife of the shown wire stripping machine to drive the wires to move inwards for cutting, and the rest are the same as in Embodiment 1. In this example, the transmission mechanism adopts a belt drive. The outer wrapping layer contains thin wire waste wires with multiple strands of non-metallic wrapping layers and metal cores. The waste wires with an outer diameter of 5-80mm have good adaptability. Compared with the machine without pressure roller 4, the outer wrapping layer The ratio of separation from the internal thin lines has increased by about 72% from the original 20% to about 92%. If the thin wire in the outer wrapping layer is more than 5mm, it can be applied to this machine to separate the wrapping layer from the metal core. If it is a thin wire below 5mm, it can be separated by cutting and separating.

Embodiment 3

[0028] The structure of stripping machine is identical with embodiment 2, difference is in figure 1 The slitting knife of the wire stripper shown is not a rotating knife, but a Figure 5 Two fixed knives 12 arranged up and down are shown. When the waste electric wire passes in the direction indicated by the arrow, the fixed knife cuts the outer layer of the package, and then the outer layer of the package is separated from the metal core by the rear rotating pressure roller and discharged. The separation ratio of the cladding layer from the metal core is also close to that of the rotary knife machine, at 94-95%. After the fixed knife is used, it has a significant effect on the initial knife used, but due to the small action surface, heavy load, fast passivation, and frequent replacement. Therefore, it is more suitable for cables with thicker coatings. In addition, if the wrapping layer contains wires of materials such as hemp rope, it is more suitable for the models shown i...

Abstract

The invention relates to a method and a device thereof for automatically peeling and splitting scrap electrical wires. The method comprises the following steps of: sectioning a coating layer of a single electric wire or an electric cable via a sectioning mechanism in the axial direction and then further separating the coating layer from a metal core by radial extrusion. The device at least comprises a feeding mechanism, a sectioning mechanism, an automatic splitting mechanism, an electromotor and a transmission mechanism. Two rotatable compression rollers with insection or two smooth rotatable compression rollers are mounted up and down behind the sectioning mechanism, and the electric wire sectioned by the sectioning mechanism penetrates through the two compression rollers, and the gap between the two compression rollers can be adjusted. By adopting the structure, a wire stripping machine not only strips waste electric wires, but also completely separates the coating layer from the metal core, realizes the automatic operation, has high operation speed, improves the efficiency and reduces the cost.

Description

technical field [0001] The invention relates to a method and equipment for stripping and separating wrapping layers and metal cores of waste electric wires, and is suitable for stripping and separating wrapping layers and metal cores of waste electric wires and cables. Background technique [0002] Resource recovery of waste wires and cables is very important for both environmental protection and resource reuse. Among them, automatic wire stripping machines with thicker wire diameters are commonly used to peel off the wrapping layer and the metal core. Therefore, the wire stripping machine is a device that is widely used in the field of recycling and processing of waste wires and cables. It adopts cutting operation, the working principle is to introduce a single regular wire into the wire feeding hole, and use a rotating blade or a fixed blade to cut the wrapping layer along the axis of the wire, so as to realize the plastic wrapping layer and the metal core. stripping. H...
