Description

Technical Field

[0001] This application relates to the field of cable stripping technology, and in particular to a cable stripping device for power engineering. Background Technology

[0002] Cables, as the core carriers of power transmission and signal communication, possess enormous recycling value after their lifespan. Their structure typically includes an outer protective sheath, an inner metal shielding layer for electromagnetic shielding, and the core conductive wire.

[0003] A search revealed Chinese utility model patent publication number CN218088318U, which discloses a cable stripping machine. After one end of the cable is inserted into a slot, the first hydraulic telescopic cylinder is activated via the control panel. Under the action of the first hydraulic telescopic cylinder, a U-shaped frame and guide wheels move towards the cable side, allowing the two sets of guide wheels to clamp the outer surface of the cable. The first servo motor is then activated, driving the guide wheels to rotate via a conveyor belt. The force of the rotating guide wheels moves the cable towards the winding assembly. Through the provided conveying assembly, the cable can be conveyed, cut, and stripped, thus solving the problems of existing cable stripping machines.

[0004] Regarding the aforementioned technologies, the inventors believe the following technical shortcomings require improvement: While traditional mechanical wire stripping has a large processing capacity, it is a crude recycling method with high equipment investment and energy consumption. Furthermore, during the crushing process, the intermingling and contamination of different materials are unavoidable, resulting in low purity of the recovered metals and significantly reduced quality of the plastics, drastically lowering their economic value. In particular, shielding layer materials with specific functions completely lose their structural value after crushing and can only be treated as low-grade waste, making it difficult to achieve complete and undamaged separation of the various structural layers of the cable. Utility Model Content

In addition, during the crushing process, the intermingling and contamination of different materials are unavoidable, resulting in low purity of recycled metals and a significant reduction in plastic quality, thus greatly reducing economic value.

[0006] This application provides a cable stripping device for power engineering, employing the following technical solution:

[0007] A cable stripping device for power engineering includes a conductor roller, a raised platform, an electric rotary table, an embedded turntable, a slow turntable, an inner layer recovery assembly, a wire stabilizing assembly, and a sheath cutting assembly. The conductor roller is disposed on both sides of the raised platform. The electric rotary table is installed on the inner side of the raised platform. The embedded turntable is installed on the inner side of the electric rotary table. The slow turntable is movably connected to the outer side of the raised platform. The inner layer recovery assembly is installed on the outer side of the slow turntable. The wire stabilizing assembly is installed on the inner side of the embedded turntable. The sheath cutting assembly is installed on the outer side of the embedded turntable.

[0008] In one feasible technical solution of this application, the inner layer recycling component includes a servo motor, a positioning shaft, an alloy cam, a smooth dial plate, and an inner layer positioning part. The servo motor is installed on the top of the elevated platform. The positioning shaft is fixedly connected to the outside of the output end of the servo motor. The alloy cam is sleeved on the outside of the positioning shaft. The smooth dial plate is fixedly connected to the outside of the slow turntable, and the outer surface of the smooth dial plate is slidably connected to the protruding end surface of the alloy cam. The inner layer positioning part is installed on the outside of the slow turntable.

[0009] In one feasible technical solution of this application, the inner positioning part includes a transverse support plate, a pneumatic finger, a convex plate, and an electric telescopic rod. The transverse support plate is fixedly connected to the outside of the slow turntable. The pneumatic finger is installed on one side of the transverse support plate and is used to clamp the shielding layer and the waterproof insulation layer. The convex plate is fixedly connected to the top of the slow turntable. The electric telescopic rod is fixedly connected to one side of the convex plate, and the output end of the electric telescopic rod is fixedly connected to the surface of the transverse support plate.

[0010] In one feasible technical solution of this application, the stabilizing assembly includes a shaft lug plate, an abutment ball, and a compression spring. The shaft lug plate is movably connected to the inner side of the embedded turntable, the abutment ball is sleeved on the outer side of the central axis of the shaft lug plate, and the two sides of the compression spring are fixedly connected to the surfaces of the shaft lug plate and the embedded turntable, respectively.

[0011] In one feasible technical solution of this application, the sheath cutting assembly includes an inclined bracket, a push cylinder, a connecting plate, and a lateral cutting plate. The inclined bracket is fixedly connected to the outside of the embedded turntable. The push cylinder is installed on one side of the inclined bracket. The connecting plate is fixedly connected to the outside of the output end of the push cylinder and is slidably connected to the middle of the inclined bracket. The lateral cutting plate is fixedly connected to one side of the connecting plate and is used for lateral cutting of the cable sheath.

[0012] In one feasible technical solution of this application, a laser displacement sensor for detecting the cutting thickness is also installed on the outer side of the connecting plate.

[0013] In one feasible technical solution of this application, the side of the transverse support plate away from the pneumatic finger is provided with a placement groove for recovering the inner shielding layer and waterproof insulation layer of the cable sheath.

[0014] In one feasible technical solution of this application, the inner side of the slow turntable is further provided with a limiting groove that matches the size of the connection between the transverse support plate and the turntable.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] In this device, the lateral cutting plate in the sheath cutting assembly, under the precise control of a laser displacement sensor, cuts only the sheath without damaging the inner layer. Subsequently, the pneumatic fingers of the inner layer recycling assembly can hold the exposed shielding layer and waterproof insulation layer endpoints. Through a servo motor driving an alloy cam and other structures, a slow turntable is rotated, winding the complete, strip-shaped shielding and insulation layers into the placement groove of the transverse support plate. This allows the shielding layer material, which would otherwise become low-grade impurities after crushing, to be recycled in a state of high purity and high structural integrity.

[0018] The inner layer recycling component achieves automated winding and recycling of the inner layer material through a servo motor and cam mechanism, resulting in neat and complete winding. The cable stabilizing component provides flexible radial constraint to the cable through the cooperation of a contact ball and a compression spring, ensuring the cable remains stable during rotation and pulling, thus providing a foundation for precise cutting and smooth winding. The entire device achieves semi-automatic or even automated operation from stripping to inner layer recycling, with high processing efficiency, stable and reliable product quality, and low labor intensity, perfectly solving the problems of low efficiency and unstable quality of manual stripping. In addition, the electric rotary table, embedded turntable, and slow turntable constitute the main drive frame, allowing actions such as sheath cutting, core stabilization, and inner layer winding to be performed synchronously or sequentially, ensuring a smooth process.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a cable stripping device for power engineering. (Refer to...) Figures 1 to 6 The cable stripping device for power engineering includes a conductor roller 1, an elevated platform 2, an electric rotary table 3, an embedded turntable 4, a slow turntable 5, an inner layer recovery assembly 6, a wire stabilizing assembly 7, and a sheath cutting assembly 8. The conductor roller 1 is arranged on both sides of the elevated platform 2. The electric rotary table 3 is installed on the inner side of the elevated platform 2. The embedded turntable 4 is installed on the inner side of the electric rotary table 3. The slow turntable 5 is movably connected to the outer side of the elevated platform 2. The inner layer recovery assembly 6 is installed on the outer side of the slow turntable 5. The wire stabilizing assembly 7 is installed on the inner side of the embedded turntable 4. The sheath cutting assembly 8 is installed on the outer side of the embedded turntable 4.

[0039] The inner layer recycling component 6 includes a servo motor 61, a positioning shaft 62, an alloy cam 63, a smooth dial plate 64, and an inner layer positioning part 9. The servo motor 61 is mounted on the top of the elevated platform 2. The positioning shaft 62 is fixedly connected to the outside of the output end of the servo motor 61. The alloy cam 63 is sleeved on the outside of the positioning shaft 62. The smooth dial plate 64 is fixedly connected to the outside of the slow turntable 5, and the outer surface of the smooth dial plate 64 is slidably connected to the protruding end surface of the alloy cam 63. The inner layer positioning part 9 is mounted on the outside of the slow turntable 5.

[0040] The inner positioning part 9 includes a transverse support plate 91, a pneumatic finger 92, a protruding plate 93, and an electric telescopic rod 94. The transverse support plate 91 is fixedly connected to the outside of the slow turntable 5. The pneumatic finger 92 is installed on one side of the transverse support plate 91 and is used to clamp the shielding layer and the waterproof insulation layer. The protruding plate 93 is fixedly connected to the top of the slow turntable 5. The electric telescopic rod 94 is fixedly connected to one side of the protruding plate 93, and the output end of the electric telescopic rod 94 is fixedly connected to the surface of the transverse support plate 91.

[0041] The cam profile interacts with the smooth dial plate 64 fixed on the slow turntable 5, converting the continuous rotation of the servo motor 61 into a smooth, intermittent slow rotation of the slow turntable 5. The slow turntable 5 drives the transverse support plate 91 and its pneumatic fingers 92 to rotate synchronously through the limiting groove 12, thereby completely and smoothly winding and storing the shielding layer and waterproof insulation layer in the mounting groove 11 of the transverse support plate 91.

[0042] The stabilizing assembly 7 includes a shaft lug plate 71, an abutment ball 72, and a compression spring 73. The shaft lug plate 71 is movably connected to the inner side of the embedded turntable 4. The abutment ball 72 is sleeved on the outer side of the central axis of the shaft lug plate 71. The two sides of the compression spring 73 are fixedly connected to the surfaces of the shaft lug plate 71 and the embedded turntable 4, respectively.

[0043] The cable is guided to the machining center via guide rollers 1 on both sides of the raised platform 2 and passes through the embedded turntable 4. During this process, the cable stabilizing assembly 7, consisting of a shaft lug plate 71, abutment ball 72, and compression spring 73, provides flexible radial constraint for the cable, effectively suppressing its swaying during subsequent rotation and pulling operations, laying the foundation for precise machining.

[0044] The sheath cutting assembly 8 includes an inclined bracket 81, a push cylinder 82, a connecting plate 83, and a lateral cutting plate 84. The inclined bracket 81 is fixedly connected to the outside of the embedded turntable 4. The push cylinder 82 is installed on one side of the inclined bracket 81. The connecting plate 83 is fixedly connected to the outside of the output end of the push cylinder 82 and is slidably connected to the middle of the inclined bracket 81. The lateral cutting plate 84 is fixedly connected to one side of the connecting plate 83 and is used for lateral cutting of the cable sheath.

[0045] The cylinder 82 drives the connecting plate 83 and the lateral cutting plate 84 to feed the cable. Crucially, the laser displacement sensor 10 mounted on the connecting plate 83 monitors the cable's outer diameter in real time and provides feedback on the cutting depth, forming a closed-loop control system. This ensures that the lateral cutting plate 84 can accurately cut into the sheath to the predetermined depth, completely avoiding damage to the internal functional layers. After cutting, the cable sheath can be completely extracted.

[0046] A laser displacement sensor 10 for detecting the cutting thickness is also installed on the outside of the connecting plate 83.

[0047] A groove 11 for retrieving the inner shielding layer and waterproof insulation layer of the cable sheath is provided on the side of the transverse support plate 91 away from the pneumatic finger 92.

[0048] The inner side of the slow turntable 5 is also provided with a limiting groove 12 that matches the size of the connection between the horizontal support plate 91 and the turntable 5.

[0049] The connection between the elevated platform 2 and the slow turntable 5 is also equipped with finely ground support rods 13 and circular grooves 14 that are compatible in size.

[0050] The usage process of the cable stripping device for power engineering in this embodiment is roughly as follows:

[0051] The cable to be processed is first guided into the central working area of ​​the equipment via the guide rollers 1 on both sides of the elevated platform 2. The cable passes through the center of the embedded turntable 4 and enters the channel formed by the cable stabilizing assembly 7. Under the action of the compression spring 73, the shaft lug 71 of this assembly applies flexible radial pressure to the cable through the contact ball 72, ensuring the cable remains stable during subsequent processing and preventing swaying. At the same time, the sheath cutting assembly 8 starts to work, and its push cylinder 82 drives the connecting plate 83 to slide along the inclined bracket 81, thereby driving the lateral cutting plate 84 to feed the cable. During this process, the laser displacement sensor 10 installed on the connecting plate 83 monitors the cable outer diameter and cutting depth in real time, forming a closed-loop control to ensure accurate cutting depth, cutting only the sheath without damaging the internal functional layers. After the annular cut is completed, the cable sheath that has been annularly cut can be pulled out by an external traction device. After the sheath is peeled off, the cable's shielding layer and waterproof insulation layer will be exposed. At this time, the inner layer positioning part 9 starts to operate. The electric telescopic rod 94 pushes the transverse support plate 91 toward the cable, allowing the pneumatic fingers 92 mounted on it to accurately clamp the exposed ends of the shielding layer and waterproof insulation layer. During this process, the servo motor 61 starts, driving the positioning shaft 62 and alloy cam 63 to rotate. The contour surface of the alloy cam 63 slides into contact with the smooth dial plate 64 fixed on the slow turntable 5, converting the continuous rotation of the servo motor 61 into intermittent, smooth, slow rotation of the slow turntable 5. The slow turntable 5 drives the transverse support plate 91 to rotate synchronously through its inner limiting groove 12. The shielding layer and waterproof insulation layer, clamped by the pneumatic fingers 92, are completely wound and retracted into the placement groove 11 on its side as the transverse support plate 91 rotates. The stability of the entire rotation process is ensured by the precise fit of the finely ground support rod 13 and the circular groove 14 at the connection between the elevated platform 2 and the slow turntable 5. Finally, the transverse support plate 91, fully wound with the inner layer material, can be removed for material recycling.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
