Description

Technical Field

[0001] This utility model relates to the field of stripping device technology, and in particular to a convenient stripping device for recycling wires and cables. Background Technology

[0002] A hand-cranked cable recycling device is a manual stripping machine specifically designed for the cable recycling process. It can be defined as a device that uses a hand-cranked drive mechanism to operate the internal cutting components, separating the outer insulation of the cable from the metal core, thus achieving efficient cable recycling. Specifically, this device typically consists of a hand crank, a transmission gear set, a housing, a circular cutting blade, guide wheels, and a waste collection trough. Its core function is to allow manual cranking of the handle to cause the cutting blade to cut radially into the insulation of the cable, while the guide wheels pull the cable forward, completing the continuous stripping of the insulation. Its application is crucial in the cable recycling field.

[0003] Current hand-cranked cable stripping devices suffer from significant maintenance inconvenience due to their built-in circular cutter and lack of convenient grinding mechanisms. The existing devices typically have a circular cutter fixed inside the housing, with its blades arranged in a ring. The initial design intention was to achieve uniform cutting of the insulation by the contact between the ring-shaped blades and the cable surface. However, in actual use, the cutter is prone to chipping and dulling due to prolonged friction with the tough insulation, leading to decreased stripping efficiency and potentially damaging the metal core wire due to incomplete cutting. Because the cutter is located inside the device and closely adjacent to the transmission components and guide structure, grinding requires disassembling multiple parts, including the housing and transmission gear set, to expose the cutter surface. This cumbersome process is prone to damaging internal components. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a convenient stripping device for recycling wires and cables, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a convenient stripping device for wire and cable recycling, including a frame. A stripping roller is rotatably connected to the inside of the frame via bearings. A threaded post is threadedly connected to the top of the frame, and a lifting frame is rotatably connected to the bottom of the threaded post via bearings. The lifting frame is slidably connected to the frame. An annular cutting blade is rotatably connected to the inside of the lifting frame via bearings, and the annular cutting blade corresponds to the top and bottom. Limiting slots are formed through the left and right sides of the lifting frame. A threaded sleeve is slidably connected to the inner wall of each limiting slot. Two threaded sleeves are connected together... A U-shaped frame is fixedly connected between the two threaded sleeves. A locking bolt is threaded onto the inner wall of each threaded sleeve. The nuts of the two locking bolts are fitted against the left and right sides of the lifting frame. A grinding stone is slidably connected to the inner wall of the U-shaped frame. The grinding stone is located above the annular cutting blade. A frame is fixedly connected to the top of the grinding stone. The frame is slidably connected to the U-shaped frame. Two symmetrically arranged control plates are slidably connected to the inner wall of the frame. A spring is fixedly connected between the two control plates. A locking pin is fixedly connected to the side of each control plate away from the spring. Both locking pins penetrate the frame and engage with the U-shaped frame.

[0007] Preferably, in any of the above solutions, the top of the U-shaped frame is provided with an assembly groove, and the frame is slidably connected to the U-shaped frame through the assembly groove. The assembly groove restricts the sliding direction of the frame, ensuring that the frame drives the grinding stone to accurately align with the annular cutting blade, avoiding uneven grinding caused by the grinding stone shifting during grinding. At the same time, the sliding connection method facilitates the frame to move back and forth for grinding operations, improving grinding efficiency.

[0008] Preferably, the inner wall of the assembly slot has two symmetrically arranged locking holes. Both locking pins pass through the frame and engage with the U-shaped frame through the locking holes. When grinding is not required, the locking pins engage with the locking holes to prevent the frame and grinding stone from sliding accidentally, thus avoiding unnecessary contact between the grinding stone and the ring cutting blade and causing wear. When grinding is required, pressing the control plate will disengage the locking pins from the locking holes, making the operation convenient and balancing safety and flexibility.

[0009] Preferably, one end of the annular cutting blade is fixedly connected to a spline sleeve, the inner wall of the spline sleeve is slidably connected to a spline shaft, and the end of the spline shaft away from the annular cutting blade is fixedly connected to a crank handle. The spline connection ensures that the rotational force of the crank handle can be effectively transmitted to the annular cutting blade, and also allows the annular cutting blade to remain connected to the spline shaft when it moves up and down with the lifting frame, without affecting the height adjustment, and ensuring that the cutting blade can rotate normally in different positions to perform peeling operations.

[0010] Preferably, the bottom surface of the whetstone is provided with a grinding groove, and the annular cutting blade is slidably connected to the whetstone through the grinding groove. The shape of the grinding groove is adapted to the blade of the annular cutting blade, so that the whetstone can fully contact the blade during the sliding process, ensuring that each part can be evenly ground, avoiding the problem of incomplete grinding by traditional flat whetstones, and ensuring the sharpness of the annular cutting blade.

[0011] Preferably, as described in any of the above schemes, guide plates are fixedly connected to both the left and right sides of the lifting frame, and both guide plates are slidably connected to the frame. The guide plates restrict the movement trajectory of the lifting frame, preventing it from tilting or shaking during up and down movement, ensuring that the annular cutting blade and the stripping roller always remain parallel and aligned, avoiding uneven stripping of the cable or damage to the metal core wire due to the deviation of the cutting blade, and improving the operational stability of the device.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. The specific operating steps for sharpening the ring-shaped cutting blade are as follows: First, loosen the locking bolt to allow the threaded sleeve to slide along the limiting groove, causing the U-shaped frame and grinding stone to move down and contact the ring-shaped cutting blade. Then, tighten the locking bolt to fix the position of the threaded sleeve. Subsequently, use the crank handle to move the ring-shaped cutting blade inside the sharpening groove. This operating procedure enables convenient sharpening of the ring-shaped cutting blade without disassembling the lifting frame or other components. By adjusting the lifting of the U-shaped frame and the position of the grinding stone, the built-in ring-shaped cutting blade can be directly processed. The sharpening groove conforms to the shape of the blade to ensure uniform sharpening, and the cooperation between the locking pin and the locking hole ensures a stable sharpening process. This solves the cumbersome problem of disassembly required for traditional sharpening devices, improves maintenance efficiency, and extends the service life of the cutting blade.

[0014] 2. When adjusting the distance between the stripping roller and the cutting blade, the specific operating steps are as follows: Rotate the threaded column to drive the lifting frame to slide along the frame. The guide plate ensures the smooth movement of the lifting frame, making the distance between the annular cutting blade and the stripping roller suitable for the cable diameter. After adjustment, use the crank handle below to drive the stripping roller to rotate, working with the annular cutting blade to strip the cable. This operating process precisely adjusts the height of the annular cutting blade through the threaded column to adapt to the stripping needs of cables of different specifications. The cooperation between the spline shaft and the spline sleeve ensures stable power transmission, and the guide plate enhances the movement stability of the lifting frame, preventing the cutting blade from deviating and causing uneven stripping. The overall structure balances adjustment flexibility and operational stability, improving the device's adaptability to various cables and the stripping quality. Attached Figure Description

[0027] A convenient stripping device for recycling electric wires and cables works on the following principle:

[0028] 1): First, loosen the locking bolt 9 so that the threaded sleeve 7 slides along the limiting groove 6, which will drive the U-shaped frame 8 and the grinding stone 10 to move down to contact the annular cutting blade 5. Then tighten the locking bolt 9 to fix the position of the threaded sleeve 7.
