[0002] With the rapid development of the power industry and the increasing use of cables, the recycling of waste cables has become an important link in resource recycling and environmental protection. In the cable recycling process, separating the protective layer from the core is a key step, and in the prior art, after cutting the protective layer of the cable, further separating the rubber layer and the metal layer in the protective layer is inconvenient. Traditional cable recycling stripping devices, after cutting the protective layer of the cable, due to the irregular shape of the protective layer, especially the semicircular cross-section or other curved shape, the rubber layer and the metal layer are tightly attached and have a complex structure, making it difficult to directly separate the rubber layer and the metal layer. If manual separation is used, not only is the efficiency low, the labor intensity is large, but also the separation effect is poor, which can easily cause damage to the rubber layer and the metal layer, reducing the recycling quality and utilization rate. Some existing automatic separation equipment often needs to pre-treat the protective layer, such as additional folding, stretching and other operations, which increases the complexity and operating cost of the equipment, and the separation effect is not ideal, which cannot meet the needs of large-scale and efficient cable recycling. SUMMARY

[0009] In summary, the present application has the following beneficial technical effects: 1. By arranging the flattening mechanism, the stable conveying of the protective layer is realized by using multiple conveying rollers, the first expansion ball, the second expansion ball and the compression roller in the extrusion component act on the protective layer in turn, and the protective layer with an irregular shape such as a semicircular cross section can be gradually flattened. Among them, the first expansion ball and the second expansion ball first preliminarily expand the protective layer, so that the curved parts of the protective layer are gradually unfolded, and then the compression roller further compacts, so as to ensure the flatness of the protective layer; 2. The hanging frame in the extrusion component is convenient to move along the length direction of the support frame through the cooperation of the lead screw and the sliding block, which is convenient for processing the protective layer, the push rod motor on the rotating frame can push the base plate to move, which is convenient for adjusting the contact position of the first expansion ball, the second expansion ball and the compression roller with the protective layer, and convenient for switching the first expansion ball, the second expansion ball and the compression roller; 3.

The guide wheel inside the cover is used for guiding the protective layer.
[0010] 4. After the protective layer is flattened by the flattening mechanism, the protective layer is subjected to rolling treatment by the rolling mechanism. Since the protective layer has been flattened, the bonding force between the rubber layer and the metal layer is weakened, and the separation of the two under the action of rolling can be more effectively realized.
