Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable crushing, and particularly to a special cutting and crushing device for cable outer sheaths. Background Art

[0002] For cables with signal shielding layers or multi-core cables, recycling is particularly difficult. In the prior art, the insulation layer or the outer sheath of the cable with a shielding layer is usually broken after the core is drawn off. After the outer sheath with a shielding layer is cut and broken, the metal components and rubber components are separated by a centrifuge. The metal components are handed over to the next process for smelting and purification, and the rubber components are chemically treated to break the chains into small molecules and then further processed.

[0003] During the process of cutting and crushing the cable outer sheath, the crushing knife will heat up after working for a long time, and in severe cases, it will even cause the cable outer sheath to melt and burn, emitting a pungent smell, and will accelerate the wear of the crushing knife.

A spiral discharge port that is compatible with the spiral block is provided at the bottom of the cleaning shell. The top of the spiral block extends to the inside of the spiral discharge port and is slidably connected to the inner wall of the spiral discharge port. When discharging, the material inside the cleaning shell only needs to be driven to rotate by the cleaning device to move the material to the position of the discharge port and be discharged from the discharge port. Discharging is more convenient, and the discharge port structure and opening and closing operation are simple.

[0018] The present invention provides a cable sheath cutting and crushing device, which has the following beneficial effects:

[0019] 1. A special cutting and shredding device for cable sheath is provided with a shredding device. The cable is put into the shredding cylinder through the feed port, and then the shredding shaft is driven to rotate by the driving motor. The shredding shaft drives the shredding knife to rotate through the control circle. The cable is cut during the rotation of the shredding knife. During the cutting process, the shredding knife can cooperate with the extrusion block. The cable is supported from the side by the extrusion block. Then the shredding knife moves between the extrusion blocks to cut the cable, which can provide support for the cutting operation and has a good cutting effect. An annular air duct and a diversion air duct are provided. The annular air duct sends cold air into the extrusion block through the diversion air duct and blows it onto the shredding knife through the air hole, which can cool the shredding knife and avoid the situation where the shredding knife is overheated and aggravated by wear. The air hole is provided on the side of the extrusion block, so that the shredding knife can be cooled when it moves between the extrusion blocks, and the cooling effect is good.

[0020] 2. This special cutting and crushing device for cable sheath is provided with a control circle. When the crushing knife is blunted and cannot effectively cut the cable, the crushing knife encounters increased resistance from the cable when contacting the cable. The resistance pushes the crushing knife to drive the rotating circle to rotate in the opposite direction of the inner circle inside the rotating groove, which can drive the inner wall of the arc groove to squeeze the arc spring. When the resistance is large to a certain extent and the crushing knife is blunted to a certain extent, the arc spring can escape from the inside of the arc groove and enter the inside of the control groove, squeezing the squeezing switch inside the control groove. The extrusion switch can be used to control the alarm to sound, so that the crushing knife can sound the alarm in time when it is blunted to the extent that it cannot effectively cut, thereby avoiding the situation where the cut and crushed materials do not meet the requirements and cause low processing efficiency.

[0021] 3. The special cutting and crushing device for cable sheaths is provided with a cleaning device. After the granular materials crushed by the crushing device fall into the cleaning housing, the cleaning shafts at both ends are driven by a double-headed motor to rotate in opposite directions. The cleaning shafts drive the connecting support rods to rotate, and the connecting support rods drive the cleaning brushes to rotate through the inclined plates. The upper and lower cleaning brushes move relatively, so that the materials therebetween can be squeezed and brushed. Compared with the traditional stirring and cleaning, the compression springs can provide pressing force for the inclined plates and the cleaning brushes, so that the upper and lower cleaning brushes can squeeze the materials therebetween, and the cleaning effect is better and the cleaning efficiency is higher.

[0022] 4. When the special cutting and crushing device for cable sheaths needs to discharge materials, rotate the threaded ejector rod and take out the threaded ejector rod from the bottom of the cleaning housing. The threaded ejector rod drives the spiral plug block to disengage from the spiral discharge port through the discharge tray, and then the materials inside the cleaning housing can be discharged through the spiral discharge port. Since the discharge port is spiral-shaped, when discharging materials, only need to drive the materials inside the cleaning housing to rotate through the cleaning device, and the materials can be moved to the position of the discharge port and discharged from the discharge port. The discharging is relatively convenient, and the structure and opening / closing operation of the discharge port are simple. BRIEF DESCRIPTION OF THE DRAWINGS
