Description

Technical Field

[0001] This utility model belongs to the field of cable recycling technology, and in particular relates to an automatic stripping and cutting device for power cables. Background Technology

[0002] Power cables are the core wires used in power systems to transmit and distribute high-power electrical energy. When cables are no longer usable, for environmental and economic reasons, the insulation of the cables is stripped to allow for the sorting, recycling, and reuse of metals such as copper and the plastic sheath, thus avoiding waste.

[0003] Chinese utility model patent CN222508599U discloses an automatic stripping and cutting device for power cables. By inserting the power cable into a conveying trough and using conveying rollers, the cable is conveyed by crisscrossing rotation, avoiding the inconvenience of cable fixing methods, thereby reducing labor input, saving time, and improving the efficiency of stripping power cables.

[0004] Research revealed that the aforementioned devices are inconvenient for securely clamping cables of various thicknesses and sizes. Furthermore, their large size and complex structure hinder ease of use and operation, resulting in low practicality. Therefore, there is an urgent need to improve existing automatic power cable stripping and cutting devices and provide a new type of automatic power cable stripping and cutting device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing an automatic stripping and cutting device for power cables that is reasonably designed, simple in structure, relatively small in size, easy to operate, and applicable to various types and sizes of cables, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic stripping and cutting device for power cables includes a base plate, an electric telescopic rod, and a drive motor. The upper surface of the base plate is symmetrically fixed with mounting brackets. Auxiliary guide wheels are bearing-mounted at the top of each of the two mounting brackets. A support is fixedly installed on the upper rear of the base plate. The top of the support is symmetrically fixed with the electric telescopic rod. A movable frame is fixedly connected to the telescopic end of the electric telescopic rod. A pushing component and a cutting component are provided in the middle of the movable frame. Second horizontal shafts are bearing-mounted at both ends of the movable frame. An active guide wheel is fixedly sleeved on the outer side of the middle of the second horizontal shaft. A large gear is fixedly connected to the rear end of the second horizontal shaft. A drive motor is fixedly installed on the left front outer wall of the movable frame, and the output end of the drive motor is fixedly connected to the front end of the left second horizontal shaft.

[0008] In a preferred embodiment, the two auxiliary guide wheels are located directly below the two active guide wheels. The middle part of both the auxiliary guide wheels and the active guide wheels is provided with a concave surface, and an anti-slip outer skin is bonded to the concave surface. The anti-slip outer skin is made of elastic rubber.

[0009] In a preferred embodiment, the active guide wheel is linked to the cutting component through the pushing component, and the two active guide wheels always rotate in the same direction and at the same speed.

[0010] In a preferred embodiment, the pushing assembly includes a first horizontal shaft, a circular block, and a small gear. The first horizontal shaft bearing is installed at the top center of the movable frame. The top of the movable frame has a groove-like structure. The circular block is fixedly sleeved on the outer side of the middle of the first horizontal shaft. The small gear is fixedly connected to the rear end of the first horizontal shaft.

[0011] In a preferred embodiment, the pinion is meshed between the two large gears, the two large gears having the same diameter and not in contact with each other.

[0012] In a preferred embodiment, the slitting assembly includes a movable block, a through groove, and a slitting blade. The movable block is engaged and slidably located within a groove-shaped structure at the top of the movable frame. The through groove is provided inside the movable block, and the slitting blade is fixedly installed at the bottom center of the movable block by bolts.

[0013] In a preferred embodiment, the movable block is movably fitted onto the outside of the circular block, and the circular block is eccentrically positioned outside the first horizontal axis.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] The movable frame can be stably raised and lowered in the vertical direction by controlling the electric telescopic rod, which facilitates quick adjustment of the distance between the active guide wheel and the auxiliary guide wheel to meet the clamping and stripping requirements of cables of different sizes. Moreover, both the auxiliary guide wheel and the active guide wheel have concave surfaces in the middle, and the concave surfaces are bonded with rubber anti-slip outer skin, which facilitates stable clamping and conveying of cables. It is also convenient to stably cut the cable outer sheath with the cutting blade, which facilitates the separation of the cable outer sheath from the internal metal wire.

[0017] When the two large gears rotate, the small gear can drive the first horizontal shaft and the circular block to rotate quickly. Since the circular block is eccentrically set outside the first horizontal shaft, it can squeeze the movable block with a through groove inside when it rotates. This causes the movable block to drive the slitting blade to move up and down rapidly in the movable frame, which helps to reduce slitting resistance. The outer skin slitting is more stable, smoother, and more efficient. Moreover, the device is relatively small in size, simple in structure, and easy to operate. Attached Figure Description

[0026] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0027] like Figure 1-5As shown, the automatic stripping and cutting device for power cables of this utility model includes a base plate 1, an electric telescopic rod 5, and a drive motor 9. A fixed frame 2 is symmetrically fixed to the upper surface of the base plate 1. Auxiliary guide wheels 3 are mounted on the top of each of the two fixed frames 2 via bearings. A bracket 4 is fixedly installed on the upper rear of the base plate 1. Electric telescopic rods 5 are symmetrically fixedly installed on the top of the bracket 4. A movable frame 6 is fixedly connected to the telescopic end of the electric telescopic rod 5. A pushing component 7 and a cutting component 8 are provided in the middle of the movable frame 6. A second horizontal shaft 10 is mounted on both the left and right ends of the movable frame 6 via bearings. An active guide wheel 11 is fixedly sleeved on the outer side of the middle of the second horizontal shaft 10. A large gear 13 is fixedly connected to the rear end of the second horizontal shaft 10. A drive motor 9 is fixedly installed on the left front outer wall of the movable frame 6. The output end of the drive motor 9 is fixedly connected to the front end of the left second horizontal shaft 10.

[0028] Based on the above structure, two auxiliary guide wheels 3 are located directly below the two active guide wheels 11. Both the auxiliary guide wheels 3 and the active guide wheels 11 have concave surfaces in the middle, and anti-slip outer skin 12 is bonded to the concave surfaces. The anti-slip outer skin 12 is made of elastic rubber.

[0029] In this embodiment, both the auxiliary guide wheel 3 and the active guide wheel 11 have concave surfaces in the middle, and the concave surfaces are bonded with anti-slip rubber outer skin 12, which facilitates stable clamping and transmission of the cable.

[0030] Based on the above structure, the active guide wheel 11 is linked with the cutting component 8 through the pushing component 7, and the two active guide wheels 11 always rotate in the same direction and at the same speed.

[0031] In this embodiment, the two active guide wheels 11 rotate at the same speed and in the same direction, which facilitates the stable transmission of the cable.

[0032] Based on the above structure, the pushing component 7 includes a first horizontal shaft 71, a circular block 72 and a small gear 73. The first horizontal shaft 71 is mounted on the top center of the movable frame 6. The top of the movable frame 6 has a groove structure. The circular block 72 is fixedly sleeved on the outer side of the middle of the first horizontal shaft 71. The rear end of the first horizontal shaft 71 is fixedly connected to the small gear 73.

[0033] Based on the above structure, the pinion 73 is meshed between two large gears 13, the two large gears 13 having the same diameter and not contacting each other.

[0034] In this embodiment, when controlling the rotation of the large gear 13, it is convenient to use the small gear 73 that meshes with the large gear 13 to drive the first horizontal shaft 71 and the circular block 72 to rotate, and the rotation speed of the small gear 73 is greater than the rotation speed of the large gear 13.

[0035] Based on the above structure, the slitting assembly 8 includes a movable block 81, a through groove 82 and a slitting blade 83. The movable block 81 is engaged and slidably located in the groove structure opened at the top of the movable frame 6. The through groove 82 is opened inside the movable block 81. The slitting blade 83 is fixedly installed at the bottom center of the movable block 81 by bolts.

[0036] Based on the above structure, the movable block 81 is movably sleeved on the outside of the circular block 72, and the circular block 72 is eccentrically positioned on the outside of the first horizontal axis 71.

[0037] In this embodiment, when the first horizontal axis 71 drives the circular block 72, which is eccentrically fixed on its outer side, to rotate, the circular block 72 can squeeze the movable block 81 with the through groove 82 inside, so that the movable block 81 drives the cutting blade 83 to reciprocate and rise and fall quickly, which helps to reduce the cutting resistance to the cable sheath and makes the cutting of the cable sheath more stable and smooth.

[0038] The working principle of this utility model is as follows:

[0039] In use, the cable to be stripped is first placed in the concave surface of the two auxiliary guide wheels 3, and the cutting blade 83 cuts the cable sheath. Then, the electric telescopic rod 5 is activated to control the movable frame 6 to move vertically downward. The active guide wheel 11 is used to press the cable on top of the auxiliary guide wheels 3. Then, the drive motor 9 is activated to control the active guide wheel 11, the second horizontal shaft 10 and the large gear 13 to rotate synchronously, which facilitates the cable to start transmission. Moreover, the small gear 73 that meshes with the large gear 13 facilitates the synchronous and rapid rotation of the first horizontal shaft 71 and the circular block 72. The circular block 72, which is eccentrically fixed to the outside of the first horizontal shaft 71, can squeeze the movable block 81 with a through groove 82 inside when rotating. The movable block 81 drives the cutting blade 83 to reciprocate and move up and down rapidly in the movable frame 6, thereby reducing the cutting resistance to the cable sheath. The cable sheath cutting is more stable, smooth and efficient.

[0040] This device allows for quick adjustment of the distance between the auxiliary guide wheel 3 and the active guide wheel 11, facilitating the clamping and stripping of cables of different sizes. Both the auxiliary guide wheel 3 and the active guide wheel 11 have concave surfaces in the middle, with rubber anti-slip outer sheath 12 bonded inside the concave surfaces, which facilitates stable clamping and conveying of the cable. It also allows for stable cutting of the cable sheath by the cutting blade 83, facilitating the separation of the cable sheath from the internal metal wires. Furthermore, the device is relatively small in size, simple in structure, and easy to operate.

[0041] It should be noted that this device is powered by an external power source. The electric telescopic rod 5 and the drive motor 9 are existing electrical products, and their specific control methods are mature technologies, not innovative improvements in this case, so they will not be described in detail.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
