Description

Technical Field

[0001] This utility model relates to the field of cable stripping, and in particular to a cable stripping device. Background Technology

[0002] Cables are typically made of a variety of high-quality materials, including metallic materials such as copper and aluminum, and non-metallic materials such as plastics and rubber. When recycling these cables, stripping away the outer sheath and insulation is crucial, as this step significantly improves the purity of the recycled metals. High-purity metals not only have higher reuse value but are also easier to process and handle.

[0003] If cables are directly melted down or recycled without being stripped, their internal non-metallic components (such as plastics and rubber) may release toxic and harmful gases under high-temperature conditions, posing a serious threat to the ecological environment. Furthermore, metals containing impurities may also pose environmental risks during reuse. Therefore, wire stripping is not only crucial for improving metal purity but also an important step in reducing environmental pollution and protecting the ecological environment.

[0004] Wire stripping effectively separates the metal and non-metal components of cables, greatly facilitating subsequent recycling and processing. This not only significantly improves recycling efficiency but also effectively reduces recycling costs. The stripped metal parts can directly enter the metal recycling process, while the non-metal parts can be sent to the appropriate plastic or rubber recycling processes, thereby maximizing and efficiently utilizing resources. This approach not only contributes to resource recycling but also promotes the sustainable development of environmental protection.

[0005] Chinese patent application CN202323199715.8 discloses a power cable stripper, comprising: a base plate, a fixing plate fixedly installed on one side of the top outer surface of the base plate, an arc-shaped plate fixedly installed on the top of the fixing plate, and multiple support rods fixedly installed on the top of the base plate near the outer surface of the arc-shaped plate. One end of the cable to be stripped is placed on the outer surface of the arc-shaped plate, and then multiple electric push rods are activated to move the arc-shaped plate downwards, bringing it into contact with the outer surface of the cable. This clamps cables of different sizes, preventing shaking and potential danger during stripping. Multiple ball bearings are provided on the opposing surfaces of the arc-shaped plate and the arc-shaped plate, facilitating the pushing of the cable for stripping. Simultaneously, two hydraulic cylinders are activated to move the blades to the cutting grooves, allowing the cable's outer sheath to be stripped as it is pushed.

[0006] However, the aforementioned power cable stripper has a problem: when stripping the wire, after the rubber covering the wire core is cut open, it is still confined within the clamping space of the first and second arc plates. After the rubber is cut open, it still rubs against both sides of the blade, which not only causes greater wear on the blade but also makes the cable cutting process unsmooth. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a cable stripping device that can solve the problems of blade wear and insufficient smoothness in the cable cutting process caused by the rubber being tightly attached to the blade in the prior art.

[0008] A cable stripping device includes a horizontally placed base, on which a cutting part for cutting cables and a pulling part for pulling the outer sheath of cables are arranged in sequence.

[0009] The cutting part includes opposing clamping plates vertically mounted on the base. An adjustable blade is provided on the side of the clamping plate near the pulling part. The blade protrudes from the opposite side of the clamping plate. Supporting mechanisms for limiting the cable are also provided on both sides of the clamping plate.

[0010] The pulling part includes a support plate arranged on the base along the cable direction, which supports the cable. A platform is mounted above the support plate, and two meshing gears are movably embedded on the platform. The rotation surfaces of the two gears are coplanar and parallel to the top surface of the base. An operating lever is mounted on the top surface of one of the gears. A movable shaft passing through the top surface is coaxially mounted below each gear. A vertical movable roller is mounted on the side of the movable shaft away from the cable. Rotating the operating lever can cause the lower movable roller to rotate around the axis of the movable shaft. The operating lever can also be fixed at a specific angle by a fixing mechanism set on the platform to fix the lower movable shaft. A drive roller is vertically mounted on the side of the movable roller away from the cable, which is driven by a drive device on one side of the base. After the movable roller rotates to the side of the drive roller, it can cooperate to clamp the cable sheath and pull it away from the cutting part.

[0011] Furthermore, a connecting member is provided between the movable roller and the movable shaft, and the connecting member will not interfere with the support plate when the movable roller rotates about the movable shaft as an axis.

[0012] Furthermore, the driving device includes a motor disposed on one side of the base, a drive shaft mounted on the output shaft of the motor, a first bevel gear coaxially sleeved on the drive shaft, and a second bevel gear meshing with the bevel gear on the drive shaft at one end of the drive roller. The drive shaft rotates under the action of the motor, thereby driving the drive roller to rotate.

[0013] Furthermore, the platform is mounted on the base by several support columns. The support columns are provided with a bearing seat for mounting the drive roller on the side near the support plate. The drive roller can be mounted in the bearing seat and rotates around the axis of the drive roller. The second bevel gear is located at the bottom of the drive roller.

[0014] Furthermore, the clamping plate is an arc-shaped plate, and the opposing clamping plates are clamping plates with their arc-shaped concave surfaces facing each other.

[0015] Furthermore, the top surface of the base is vertically provided with a mounting bracket for mounting clamping plates. The opposing clamping plates are divided into a first clamping plate and a second clamping plate. The first clamping plate is mounted above the second clamping plate via the mounting bracket and its position relative to the second clamping plate can be adjusted on the mounting bracket. The second clamping plate is fixed below the first clamping plate by a support column.

[0016] Furthermore, the support mechanism includes spring rollers symmetrically arranged on both sides of the second clamping plate. The rotation surface of the rollers is parallel to the top surface of the base, and the spring rollers can support the cable on both sides while reducing friction.

[0017] Furthermore, the spring roller includes a mounting block, the mounting block having a clearance groove facing the opposite spring roller, a spring perpendicular to the end face of the clearance groove is fixedly mounted, the other end of the spring is connected to a slider that can move in the clearance groove, and a spring roller with a rotation surface parallel to the ground is mounted on the end of the slider away from the end face of the clearance groove.

[0018] Furthermore, the fixing mechanism includes a positioning through hole with its axis perpendicular to the platform, which is opened in the middle of the operating lever. Several positioning blind holes with their axes perpendicular to the platform are opened on the platform with the center of the gear fixed to the operating lever as the axis. After rotating to a suitable angle, the positioning pin can be inserted into the positioning through hole and the positioning blind hole to play a positioning role.

[0019] Furthermore, the drive roller is provided with alternating transverse and longitudinal patterns.

[0020] This invention has the following advantages: Addressing the problems of blade wear and uneven cable cutting caused by the rubber sheet tightly adhering to the blade in existing technologies, this invention features an adjustable-angle pulling part that allows the two longitudinally cut rubber halves to be separated laterally. Because the rubber sheet is pulled apart by the pulling part, the blade only contacts the cut area of ​​the rubber sheet through its cutting edge, while the sidewall does not come into contact with the rubber sheet. Furthermore, because the drive roller and movable roller clamp the rubber sheet, the cable is subjected to a pulling force to one side under the rotation of the drive roller. Therefore, this invention eliminates the need for an additional cable-pushing device or manual cable pushing, saving production costs. Attached Figure Description
