[0002] The recycling of insulating flexible cables is of great significance for environmental protection and resource recycling. First of all, waste cables contain a large amount of valuable metals such as copper and aluminum, as well as materials such as plastics. Through recycling, the reuse of these resources can be effectively realized, reducing the dependence on primary resources. When recycling insulating flexible cables, it is necessary to separate the conductors inside from the sheaths and classify the sheaths and conductors for processing.

At the other end of the rotating shaft, a centering shaft is provided. Inside the centering shaft, a cutter bar bracket is fixed. At both ends of the cutter bar bracket, cutter bars are respectively connected. The cutter bars are parallel to the centering shaft. At the outer ends of the two cutter bars, cutter body parts are respectively provided. The cutter body parts correspond to the centering shaft. Through the above settings, the utility model is used for stripping the sheath at one end of a hydraulic hose, can quickly strip the sheath, has accurate stripping length, adjustable cutting depth, and improves the efficiency of stripping the sheath of the hydraulic hose.

[0004] Although the above application can adjust the spacing between the cutter body parts by adjusting the worm and the worm wheel to improve the stripping accuracy, the cutter body parts always maintain a gap after adjustment, and can only strip the sheaths with a flat surface. When encountering sheaths with an uneven surface, it cannot be calibrated in time, which may lead to incomplete stripping of the sheath and affect the recycling effect of its conductors.

[0005] Therefore, an insulating flexible cable sheath stripping device is proposed to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] During specific implementation: As Figures 1-4 shown, an insulating flexible cable sheath stripping device includes:

[0022] The box body 100 is fixedly connected with two rotating wheels 300 at the middle part of the front end for guiding the insulated flexible cable; the cutter mechanism 500 includes two electric push rods 400 fixedly connected to the box body 100. The telescopic end of the electric push rod 400 is fixedly connected with a cylinder body 501. A cutter piston 5011 is arranged inside the cylinder body 501. A cutter body 5012 is fixedly connected to the opposite side of the cutter piston 5011. The surfaces of the two cylinder bodies 501 are connected with a vertical pipe 502 through an air pipe. An adjusting cylinder 504 communicated with the vertical pipe 502 is arranged inside the box body 100. A ventilation piston 5041 is arranged inside the adjusting cylinder 504. One end of the ventilation piston 5041 is fixedly connected with a spring 5043. An exhaust hole 5042 is arranged on the surface of the adjusting cylinder 504.

[0023] As Figure 2 , Figure 3 and Figure 4 shown, the cutter mechanism 500 further includes an inflation cylinder 503. An inflation piston 5031 is arranged inside the inflation cylinder 503. One end of the rotating wheel 300 is eccentrically provided with a movable rod 5032). The other end of the movable rod 5032 is hinged to the inflation piston 5031. A first one-way valve is arranged on the surface of the inflation cylinder 503. A second one-way valve is arranged at the connection between the inflation cylinder 503 and the air pipe. Limited by the first one-way valve and the second one-way valve, the gas flow direction of the inflation cylinder 503 during operation is that the outside air enters the inflation cylinder 503, and the gas in the inflation cylinder 503 flows unidirectionally to the vertical pipe 502.

[0024] In this embodiment, when the cable moves, under the action of the friction force between the two, the rotating wheel 300 rotates, thereby driving the movable rod 5032 eccentrically connected thereto to perform reciprocating operation. The movable rod 5032 will drive the inflation piston 5031 to perform reciprocating motion inside the inflation cylinder 503. During the cable stripping process, air supplement operation is continuously performed for the vertical pipe 502.

[0025] As Figure 1 , Figure 2 , and Figure 3As shown in the figure, two cutter bodies 5012 are arranged opposite to each other. One end of the cutter body 5012 penetrates the cylinder block 501 in a conical shape. Cutter limit blocks 5013 are arranged inside the cylinder block 501, and the cutter limit blocks 5013 are located below the connection between the cylinder block 501 and the air pipe. It can limit the final position of the cutter piston 5011 adjusted in the cylinder block 501, avoid excessive movement, and ensure the normal connection and operation between the vertical pipe 502 and the cylinder block 501. A limit rod is fixedly connected to the surface of the cylinder block 501. The lower end of the limit rod penetrates through a limit block, and the limit rod is slidably connected to the limit block. The limit block is fixedly connected to the box body 100. This increases the stability of the cylinder block 501 during adjustment and enables it to be adjusted along a predetermined route. Two tracks 200 are fixedly connected to the front end of the box body 100, and both opposite sides of the two tracks 200 extend out of the box body 100. The tracks 200 are used to guide and limit the inlet and outlet ends of the cable, reducing the occurrence of winding and knotting.

[0026] When the utility model is in use, first conduct the lead-in operation. The two ends of the cable are laid along the tracks 200, and the middle part is located between the two rotating wheels 300. Then conduct the debugging operation. Start the electric push rod 400 to push the cylinder block 501 closer to the surface of the cable until the cutter body 5012 contacts the surface of the cable. The cylinder block 501 continues to move, and the cutter body 5012 will slowly penetrate the sheath of the cable. The speed of the cylinder block 501 will be faster than that of the cutter body 5012. The cutter piston 5011 squeezes the gas inside the cylinder block 501, and after passing through the vertical pipe 502, it enters the adjustment cylinder 504, and the air pressure value inside it will increase, squeezing the air change piston 5041, and the spring 5043 will bend. When the air change piston 5041 moves near the exhaust hole 5042, the excess gas will be discharged, making the internal air pressure reach the preset constant value. After the debugging is completed, an external tool can be used to pull one end of the cable, and the two cutter bodies 5012 are used to strip the cable. During this process, the friction force will drive the rotating wheel 300 to rotate, thereby driving the movable rod 5032 eccentrically connected to it to perform reciprocating motion. The movable rod 5032 will drive the inflation piston 5031 to perform reciprocating motion in the inflation cylinder 503, and continuously supply air to the vertical pipe 502 during the cable stripping process.

[0027] It should be noted that in the above description, the electric push rod 400, the air pipe, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the electric push rod 400 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0028] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
