Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and particularly to a cable insulation skin cutting device for electric power construction. Background Art

[0002] As the core components of power transmission, cables and insulation sheaths have always been developed around the optimization of material properties and the improvement of safety. In traditional technologies, cables are formed by combining conductor cores and insulation skins. Cable insulation skins are often made of materials such as rubber and polyvinyl chloride. However, due to the closed sheaths, heat dissipation is poor, and continuous high temperatures may accelerate the thermal aging of the materials, affecting insulation stability. Therefore, in electric power construction, it not only includes laying new cables, but also includes detecting old cables, replacing new cables to ensure the stability of power transmission, and cutting and removing the aged cable insulation skins to recycle the conductor cores inside the cables.

[0003] However, after the existing cables are stripped of their insulation skins, only the conductor cores inside the cables are recycled, and the waste insulation skins need to be manually cleaned up a second time, which is easy to stack near the cutting device, affecting the continuous cutting efficiency of long cables.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] First, a bundling mechanism and a cutting mechanism are provided. First, the insulating skin is axially cut by the first cutting component to form two semi-circular semi-skin pieces. Then, the semi-skin pieces are cut into strips by the second cutting component. Then, they are bundled by an automatic bundling machine, pushed by the first electric telescopic rod to the stacking component, and finally received by the stacking component, and the bundled semi-skin pieces are stacked on one side, thereby realizing the rapid sorting of waste insulating skin, avoiding the situation that the continuous cutting efficiency is reduced due to the stacking of insulating skin. Further, an outer skin blowing mechanism is also provided.

[0024] Among them, the second cutting component is composed of a circumferential cutting knife, a driving part, and a telescopic part. The driving part pushes the circumferential cutting knife to move up and down. Since the cross-section of the cable is circular, when the circumferential cutting knife cuts to the middle, the telescopic part will drive the circumferential cutting knife to contract, ensuring that the semi-skin pieces are effectively cut into strips. Compared with the prior art's cutting method that surrounds the cable, the cutting method in the present invention has a simple structure and stable operation, can ensure a continuous and effective cutting effect, and the telescopic part always pushes the circumferential cutting knife against the cable to ensure an effective and stable cutting effect;

[0025] In addition, in order to improve the cutting efficiency and stability, a preheating mechanism and a cooling mechanism are provided. The insulating skin of the cable is preheated by the preheating mechanism, and then the cooling mechanism cools each blade of the cutting mechanism. After the insulating skin is preheated, it softens, making it more convenient to cut. And the low-temperature blades have higher hardness during cutting, and the softened insulating skin will not adhere to the low-temperature blades, effectively improving the cutting efficiency; further, a semiconductor refrigeration sheet is provided, the cold end of which supplies cold to the cooling mechanism, and the hot end supplies heat to the preheating mechanism, making full use of the refrigeration mechanism of the semiconductor refrigeration sheet, reducing energy waste, and achieving the purpose of energy saving;

[0026] Finally, a centering mechanism and a core wire collecting mechanism are provided. Through the thread action of the internal thread lock nut, it is ensured that each guide wheel faces the outer surface of the cable, ensuring the stability of the cable position and guaranteeing that each blade stably cuts the cable insulation skin. The core wire collecting mechanism can wind the cable conductor around the winding disc. Cooperating with the bundling mechanism, it can achieve the purpose of separating and storing the cable conductor and the insulation skin, eliminating the need for manual storage and facilitating the improvement of processing efficiency.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. In addition, it should be noted that for the sake of description, only the parts related to the invention are shown in the drawings.

[0050] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0051] Please refer to Figures 1 to 9 , an embodiment of the present invention provides a cable insulation skin cutting device for electric power construction, including:

[0052] A housing mechanism 2, including a wire passing hole 26 for the cable to pass through. The axial extension direction of the wire passing hole 26 is the first direction. The wire passing hole 26 has a feeding end and a discharging end along the first direction. The cable enters the wire passing hole 26 from the feeding end and then extends out of the wire passing hole 26 from the discharging end.

[0053] A cutting mechanism 6, arranged inside the housing mechanism 2, including a first cutting component arranged at the feeding end and two second cutting components arranged at the discharging end. The first cutting component includes an upper cutting knife 62 arranged at the top of the wire passing hole 26 and a lower cutting knife 61 arranged at the bottom along the second direction, for cutting the insulation skins at the top and bottom of the cable to form semi-skin parts distributed on both sides of the cable conductor along the third direction. Both of the two second cutting components include a circumferential cutting knife 63 that can move along the second direction. The circumferential cutting knife 63 is used to cut and separate the semi-skin parts from the insulation skin. The first direction, the second direction, and the third direction are perpendicular to each other; wherein, the first direction is Figure 1 the left-right direction in Figure 2 the up-down direction in Figure 3 the front-back direction in

[0054] A bundling mechanism 3, including an automatic bundling machine 32 arranged on the side of the discharging end away from the feeding end, and a stacking component arranged on the side of the automatic bundling machine 32 away from the discharging end. The stacking component is used to receive the bundled semi-skin parts and stack them on one side of the stacking component. The bundling mechanism 3 also includes a first electric telescopic rod 31 arranged below the wire passing hole 26. The first electric telescopic rod 31 is used to push the cable skin on the automatic bundling machine 32 to move along the first direction towards the stacking component.

[0055] As Figure 1 and Figure 2As shown, first, the insulating skin is axially cut by the first cutting assembly to form two semi-circular semi-skin pieces. Then, the semi-skin pieces are cut into strips by the second cutting assembly. Next, they are bundled by the automatic bundling machine 32, and then pushed by the first electric telescopic rod 31 towards the palletizing assembly. Finally, the palletizing assembly receives them and stacks the bundled semi-skin pieces on one side, thus achieving the rapid sorting of waste insulating skin and avoiding the situation where the continuous cutting efficiency is reduced due to the stacking of insulating skin.

[0056] In some embodiments, the housing mechanism 2 includes an inlet block 22, a central wire-passing block 21, and an outlet block 23 distributed along the first direction, as well as an upper fixing block 24 provided at the top of the central wire-passing block 21 and a lower fixing block 25 provided at the bottom; referring to Figure 4 , during assembly, first place the inlet block 22 and the outlet block 23 on the left and right sides of the central wire-passing block 21. Then, pass a long screw through the upper fixing block 24 and thread-connect it to the inlet block 22, the outlet block 23, and the central wire-passing block 21. Similarly, pass the long screw through the lower fixing block 25 and thread-connect it to the inlet block 22, the outlet block 23, and the central wire-passing block 21, thereby achieving the purpose of rapid assembly and disassembly and facilitating the installation and replacement of subsequent components.

[0057] In some embodiments, two second cutting assemblies are provided at the end of the central wire-passing block 21 away from the inlet block 22 and are distributed on both sides of the wire-passing channel 26 along the third direction. Each second cutting assembly includes:

[0058] A driving part, located on one side of the wire-passing channel 26 in the third direction, includes an internally threaded block 65 that can move up and down along the second direction;

[0059] A telescopic part, provided on the side of the internally threaded block 65 close to the wire-passing channel 26. The end of the telescopic part away from the internally threaded block 65 is connected to the circumferential cutting knife 63. When the circumferential cutting knife 63 moves along the second direction with the internally threaded block 65 and is blocked by the cable, it drives the circumferential cutting knife 63 to move along the third direction;

[0060] As Figures 4 to 8 shown, the driving part pushes the circumferential cutting knife 63 and the internally threaded block 65 to move up and down. Since the cross-section of the cable is circular, when the circumferential cutting knife 63 cuts to the middle, the telescopic part will drive the circumferential cutting knife 63 to contract, ensuring that the semi-skin pieces are effectively cut into strips. Compared with the existing cutting method that surrounds the cable, the cutting method in the present invention has a simple structure and stable operation, can ensure continuous and effective cutting, and the telescopic part always pushes the circumferential cutting knife 63 against the cable to ensure an effective and stable cutting effect.

[0061] In some embodiments, a preheating mechanism 8 is provided at the feeding end. The preheating mechanism 8 is used to pre-bake the insulating skin. A cooling mechanism 7 is provided inside the housing mechanism 2. The cooling mechanism 7 is used to reduce the temperatures of the upper cutting knife 62, the lower cutting knife 61, and the circumferential cutting knife 63. As Figures 4 to 8As shown, the insulating skin of the cable is preheated by the preheating mechanism 8, and then the cooling mechanism 7 cools each blade of the cutting mechanism 6. After the insulating skin is preheated, it softens, making it easier to cut. The low-temperature blades are harder during cutting, and the softened insulating skin will not adhere to the low-temperature blades, effectively improving the cutting efficiency.

[0062] In some embodiments, the cooling mechanism 7 includes two second channels 72 for heat exchange with the upper cutting knife 62 and the lower cutting knife 61, two first channels 71 for heat exchange with the circumferential cutting knife 63, and a coolant tank 74 internally communicating with the second channels 72;

[0063] The preheating mechanism 8 includes a pre-baking ring 83 coaxially arranged with the wire passing hole 26 at the feeding end. A second temperature transfer plate 87 is embedded at the end of the coolant tank 74 close to the preheating mechanism 8. A semiconductor refrigeration sheet 81 is provided at the end of the second temperature transfer plate 87 away from the preheating mechanism 8. The hot end of the semiconductor refrigeration sheet 81 is connected to the pre-baking ring 83, and the cold end is connected to the second temperature transfer plate 87;

[0064] As Figures 4 to 8 shown, the cold end of the semiconductor refrigeration sheet 81 supplies cold to the cooling mechanism 7, while the hot end supplies heat to the preheating mechanism 8, making full use of the refrigeration mechanism of the semiconductor refrigeration sheet 81, reducing energy waste, and achieving the purpose of energy conservation.

[0065] In some embodiments, both of the two second channels 72 are embedded and installed on the end face of the central wire passing block 21 close to the wire inlet block 22, and the two first channels 71 are embedded and installed on the end face of the central wire passing block 21 close to the wire outlet block 23. A return liquid hose 77 for connecting the two is provided between the top ends of the first channel 71 and the corresponding second channel 72. The bottom of the second channel 72 is internally communicated with the coolant tank 74. An out liquid hose 76 for connecting the two is provided between the bottom end of the first channel 71 and the coolant tank 74. A micro water pump 75 is provided on the out liquid hose 76. The micro water pump 75 is used to drive the coolant to flow into the bottom of the first channel 71 along the out liquid hose 76, flow into the top of the second channel 72 along the return liquid hose 77 from the top of the first channel 71, and flow back into the interior of the coolant tank 74 through the bottom of the second channel 72;

[0066] As Figures 4 to 8 shown, the coolant flows into the bottom of the first channel 71 along the out liquid hose 76, flows into the top of the second channel 72 along the return liquid hose 77 from the top of the first channel 71, and flows back into the interior of the coolant tank 74 through the bottom of the second channel 72, realizing the return of the entire coolant and ensuring a continuous and effective cooling effect. Among them, a temperature transfer column 73 is penetrated through the middle of the circumferential cutting knife 63. The first channel 71 is in a bracket shape. During the movement of the circumferential cutting knife 63, the temperature transfer column 73 always fits the surface of the first channel 71 to achieve the purpose of heat exchange. In addition, as Figure 5 andFigure 6 As shown, the upper cutting knife 62 and the lower cutting knife 61 are both embedded and installed at the end of the central wire-passing block 21 close to the wire-inlet block 22. The two second channels 72 have a first section that fits the upper cutting knife 62, a second section that avoids the wire-passing hole 26, and a third section that fits the lower cutting knife 61, ensuring the purpose of continuously and effectively cooling the two.

[0067] In some embodiments, the palletizing assembly includes a moving plate 36 provided on the side of the automatic strapping machine 32 away from the housing mechanism 2. On the top surface of the moving plate 36, there are two second electric telescopic rods 37 arranged along the third direction. The tops of the two second electric telescopic rods 37 are both connected by hinges to a receiving plate 39. The extending direction of its hinge axis is the first direction. A baffle 310 is provided at the edge of the top end of the receiving plate 39 away from the automatic strapping machine 32.

[0068] As Figure 1 and Figure 2 shown, the first electric telescopic rod 31 pushes the semi-finished leather pieces that have been strapped on the automatic strapping machine 32 onto the receiving plate 39. After being restricted by the baffle 310, the strapped semi-finished leather pieces stay on the receiving plate 39. At this time, when the other second electric telescopic rod 37 contracts or the other second electric telescopic rod 37 extends, the receiving plate 39 can be tilted to one side, and then the strapped semi-finished leather pieces can be stacked on one side, achieving the purpose of palletizing. Optionally, the tops of the two second electric telescopic rods 37 are both connected to the receiving plate 39 through hinge members 38. The hinge member 38 includes a first shaft seat provided at the top end of the second electric telescopic rod 37 and a second shaft seat provided at the bottom end of the receiving plate 39. The hinge axis passes through the first shaft seat and the second shaft seat to achieve the purpose of effective hinging.

[0069] In some embodiments, there are several housing mechanisms 2 and automatic strapping machines 32 arranged along the third direction and corresponding to each other. A long strip substrate 33 extending along the third direction is provided below the moving plate 36. Along the first direction on the top end of the long strip substrate 33, there are two electric slide rails 34. The extending directions of the two electric slide rails 34 are both the third direction. Sliders 35 are slidably connected to both of the two electric slide rails 34. The top end of each slider 35 is connected to the bottom surface of the moving plate 36.

[0070] As Figure 1 and Figure 2 shown, by setting multiple housing mechanisms 2, corresponding to multiple cutting mechanisms 6, preheating mechanisms 8, and cooling mechanisms 7, the purpose of simultaneous processing by multiple mechanisms is achieved. Further, as the slider 35 moves along the electric slide rail 34, the receiving plate 39 can receive the semi-finished leather pieces provided by each housing mechanism 2 and the automatic strapping machine 32, effectively improving the processing efficiency. Optionally, a frame 1 is provided at the bottom end of each housing mechanism 2 to ensure that the housing mechanism 2 has a certain height and can cooperate with the automatic strapping machine 32 for use.

[0071] In some embodiments, an outer skin air blowing mechanism 10 is provided inside the wire outlet block 23. The outer skin air blowing mechanism 10 includes air inlet channels 101 distributed on both sides of the wire passing channel 26 in the third direction. Small fans 102 are provided at the mutually remote ends of the two air inlet channels 101. Air distribution channels 103 extending upward are provided at the mutually close ends of the two air inlet channels 101. A plurality of air outlet channels 104 are arranged along the second direction on the side of the two air distribution channels 103 close to the wire passing channel 26. Each air outlet channel 104 extends obliquely in the first direction away from the wire inlet block 22 and toward the wire passing channel 26, and each air outlet channel 104 communicates with the wire passing channel 26 away from the air distribution channel 103.

[0072] As Figure 4 and Figure 9 shown, the small fan 102 introduces the external air flow into the air inlet channel 101. The air flow is distributed to each air outlet channel 104 through the air distribution channel 103. Since each air outlet channel 104 extends obliquely in the first direction away from the wire inlet block 22 and toward the wire passing channel 26, the air flow blows the cut semi-skin parts toward the automatic strapping machine 32 side, realizing the functions of automatic feeding, automatic strapping, and automatic palletizing, and effectively realizing automation and cutting processing efficiency.

[0073] In some embodiments, a centering mechanism 4 is provided on the side of the wire inlet end of the wire passing channel 26 away from the wire outlet end. The centering mechanism 4 includes an external thread sleeve 41 provided on the housing mechanism 2 and coaxially arranged with the wire passing channel 26. An internal thread lock nut 42 is threadedly connected to the end of the external thread sleeve 41 close to the housing mechanism 2. A plurality of cutting grooves 43 are provided around the other end. An installation groove 44 is provided between adjacent cutting grooves 43. A rotatable guide wheel 45 is provided inside the installation groove 44. The extending direction of the axis of the self-rotation shaft of each guide wheel 45 is perpendicular to the first direction.

[0074] Referring to Figure 3 , through the thread action of the internal thread lock nut 42, it is ensured that each guide wheel 45 faces the outer surface of the cable, ensuring the stability of the cable position. The self-rotation of the guide wheel 45 can also ensure the stable passing of the cable through the wire passing channel 26, and further ensure the stable cutting of the cable insulation skin by each blade. Optionally, a centering mechanism 4 can also be provided at the wire outlet end away from the wire inlet end, which can further improve the stability during the cable cutting process. And when pulling the cable conductor, the semi-skin parts can be driven to move synchronously under the action of static friction, ensuring that the semi-skin parts can also be sent out from the wire passing channel 26 after cutting.

[0075] In some embodiments, a core wire collecting mechanism 5 is provided at the top of the housing mechanism 2, including a winding disc 53 rotatable above the housing mechanism 2. The extending direction of the axis of the self-rotation shaft of the winding disc 53 is the third direction.

The installation shaft 52 is detachably installed at the top of the two shaft fixing plates 51, and the central sleeve of the cable reel 53 is sleeved on the installation shaft 52. The flanges of the cable reel 53 are restricted by the shaft fixing plates 51 to ensure the stable rotation of the cable reel 53.

[0077] In some embodiments, a partition plate 84 is provided between the central wire passing block 21 and the wire inlet block 22.

[0078] As Figure 4 and Figure 5 As shown in Figure 5 , the preheating ring 83 and the second channel 72 are separated by the partition plate 84 to avoid heat exchange. The heat insulation performance can ensure good preheating and cooling effects on both sides. At the same time, the settings of the second avoidance groove 86 and the first avoidance groove 85 will not interfere with the installation of the cable and the semiconductor refrigeration chip 81.

[0079] In some embodiments, the wire passing hole 26 includes a wire inlet hole 262 provided in the middle of the wire inlet block 22, a wire outlet hole 263 provided in the middle of the wire outlet block 23, and a central hole 261 provided in the middle of the central wire passing block 21. The preheating ring 83 is embedded inside the wire inlet hole 262. One outer edge of the preheating ring 83 is provided with a first temperature transfer plate 82, and the bottom end of the first temperature transfer plate 82 is connected to the hot end of the semiconductor refrigeration chip 81.

[0080] As Figure 4 As shown in Figure 4 , by inserting the preheating ring 83 into the wire inlet hole 262, the purpose of stable preheating of the preheating ring 83 is ensured, making full use of the refrigeration mechanism of the semiconductor refrigeration chip 81, effectively utilizing the heat at the hot end, and achieving the purpose of energy conservation.

[0081] In some embodiments, the housing mechanism 2 further includes a receiving cavity structure 9, and the receiving cavity structure 9 includes:

[0082] A third receiving cavity 93, provided at the top of the central wire passing block 21, for accommodating the return liquid hose 77 to avoid interference between the return liquid hose 77 and the upper fixing block 24;

[0083] The fourth accommodation cavity 94 is provided at the bottom end of the central wire-passing block 21 and is used to accommodate the liquid outlet hose 76 and the micro water pump 75 to prevent the two from interfering with the lower fixing block 25;

[0084] The first accommodation chamber 91 is provided at the end of the central wire-passing block 21 close to the wire outlet block 23 and is used to accommodate the second cutting assembly to prevent the second cutting assembly from interfering with the wire outlet block 23;

[0085] The second accommodation chamber 92 is provided at the end of the central wire-passing block 21 close to the wire inlet block 22 and is used to accommodate the semiconductor refrigeration sheet 81;

[0086] The fifth accommodation chamber 95 is provided at the end of the wire inlet block 22 close to the central wire-passing block 21 and is used to accommodate the first temperature transfer plate 82 to reduce the shaking of the first temperature transfer plate 82 and ensure that the cold end of the semiconductor refrigeration sheet 81 can stably contact and transfer with the second temperature transfer plate 87.

[0087] In some embodiments, the driving part includes a stud 64 that is arranged inside the first accommodation chamber 91, on one side of the wire-passing hole 26 in the third direction and has a stud 64 that can extend along the second direction. An internally threaded block 65 is connected to the stud 64 by a thread. The side surface of the internally threaded block 65 fits against the inner wall of the first accommodation chamber 91. One end of the stud 64 is provided with a driving motor 66;

[0088] The telescopic part includes two guide posts 67 arranged on the side surface of the internally threaded block 65. The two guide posts 67 extend toward the wire-passing hole 26 side. A sliding plate 68 is slidably connected to the ends of the two guide posts 67 away from the internally threaded block 65. The circumferential cutting knife 63 is installed on the sliding plate 68. The other end of the sliding plate 68 is provided with an adjusting spring 69, and the other end of the adjusting spring 69 is connected to the side surface of the internally threaded block 65.

[0089] As Figure 7 and Figure 8 shown, by driving the stud 64 to rotate through the driving motor 66, the internally threaded block 65 is restricted by the inner wall of the first accommodation chamber 91 to move up and down along the stud 64, thereby driving the telescopic part and the circumferential cutting knife 63 to move up and down. Since the cross-section of the cable is circular, when the circumferential cutting knife 63 cuts to the middle of the cable, the sliding plate 68 will drive the circumferential cutting knife 63 to move along the side of the internally threaded block 65, and the adjusting spring 69 will contract to ensure that the semi-skin part is effectively cut into strips. Compared with the existing cutting method that surrounds the cable, the cutting method in the present invention has a simple structure and stable operation, can ensure continuous and effective cutting, and after the adjusting spring 69 contracts, it can always push the circumferential cutting knife 63 against the cable to ensure an effective and stable cutting effect.
