Description

Technical Field

[0001] The invention relates to the technical field of cable design, and in particular to a cable recovery device. Background Art

[0002] With the rapid development of the communication industry, from the simple telephone and telegraph cables in the past to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables, wires and cables are 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. Since cables have insulating skins, the recycling of discarded cables is very important. The present invention designs a cable recycling device. The cable is passed through a cutting device, a separating device and a collecting device in sequence to separate and collect the cable core and the insulating skin. The insulating skin is separated from the cable core for the first time by a first cutting tool, and the cable core and the insulating skin are completely separated by a second cutting tool, so that they enter the separating device in a more dispersed manner for centrifugal separation, which makes the separation effect better. After complete separation, the cables are collected. The setting of a collecting device can well separate the insulating skin accidentally mixed in the cable core, and finally the separation and collection of the metal and non-metal of the cable are realized. The process is automated, which makes a great contribution to the cable and environmental protection industry. Summary of the invention

[0003] A cable recovery device designed in the present invention is characterized in that it includes a cutting device, a separating device and a collecting device connected in sequence, the cutting device includes a cutting channel and a first cutting tool and a second cutting tool arranged on the inner wall of the cutting channel, the separating device includes a centrifugal chamber and a vent hole arranged at the bottom of the centrifugal chamber, the first cutting tool includes a plurality of peeling knives distributed in a circle along the direction of the cutting channel, the second cutting tool includes a plurality of separating knives distributed perpendicular to the cutting channel, and the separating knives are arranged to intersect with each other.

[0004] Thus, the cable passes through the cutting device, the separating device and the collecting device in sequence, and finally the insulation skin and the cable core are separated. The cable first enters the cutting channel, and then is cut and separated for the first time by the first cutting tool, so that the insulation skin of the cable is separated from the cable core for the first time, and then the cable core and the insulation skin are separated for the second time by the second cutting tool, ensuring that the cable core and the insulation skin are completely separated before entering the separating device, and then further separated by centrifugation in the separating device, and finally the cable core and the insulation skin are recovered separately by the collecting device.

[0005] As a preferred embodiment of the present invention, the separation device comprises an outer shell and an inner shell, a vacuum layer is formed between the outer shell and the inner shell, the inner shell is wrapped to form the centrifugal chamber, and a motor is connected to the bottom of the inner shell to control its rotation.

[0006] As a preferred embodiment of the present invention, the separation knife includes two blades controlled by a motor, and the second cutting tool also includes a partition opening arranged on the discharge side of the separation knife.

[0007] Therefore, the partition opening is elastic and detachably connected to the cutting channel. The opening area of ​​the partition opening is between the cross-sectional area of ​​the unsheathed cable and the cross-sectional area of ​​the sheathed cable to ensure perfect separation of the insulation skin and the metal material after the secondary cutting of the cable, thereby reducing the separation burden of the separation device.

[0008] As a preferred embodiment of the present invention, the number of the peeling knives is preferably four, and the peeling knives are arranged in an arc shape along the cutting channel.

[0009] Therefore, the four peeling knives span the entire circle, that is, the blade of each peeling knife rotates 90 degrees in an arc, so that the outer insulation skin of the cable can be better separated from the cable core. After cutting, the centrifugal force during the cutting process can prevent the insulation skin from sticking to the cable core after cutting, thus preparing for the next step of separation.

[0010] As a preferred embodiment of the present invention, the cross-sectional areas at both ends of the inner shell are smaller than the cross-sectional area in the middle, and the bottom of the inner shell is funnel-shaped.

[0011] As a preferred embodiment of the present invention, the collecting device includes a water filtering layer, a metal collecting box arranged at the outlet of the water filtering layer, and a collecting box connected to the water filtering layer.

[0012] The present invention has the following beneficial effects:

[0013] The present invention has strong applicability and great development prospects. Compared with the prior art, the present invention designs a cable recovery device, which sequentially passes the cable through a cutting device, a separating device and a collecting device to separate and collect the cable core and the insulating skin. The insulating skin is separated from the cable core for the first time by a first cutting tool, and the cable core and the insulating skin are completely separated by a second cutting tool, so that they enter the separation device more dispersedly for centrifugal separation, so that the separation effect is better. After complete separation, the cables are collected, and the setting of a collecting device can well separate the insulating skin accidentally mixed in the cable core, and finally the separation and collection of the metal and non-metal of the cable are realized, which is automated and has a great contribution to the cable and environmental protection cause.
