Description

TECHNICAL FIELD

[0001] The utility model relates to the cable stripping field especially relates to a cable stripping device. BACKGROUND

[0002] Cables are usually composed of various metals (such as copper, aluminum, etc.) and non-metallic materials such as plastic and rubber. During the recycling process, the outer skin and insulating layer of the cable are stripped off, which can significantly improve the purity of the recovered metals. High-purity metals have higher value when reused and are easier to process and handle.

[0003] If the cable is not stripped, it can be directly smelted or recycled in other ways. The non-metallic parts (such as plastic and rubber) may produce toxic and harmful gases at high temperatures, causing environmental pollution. In addition, impure metals may also have a negative impact on the environment when reused. Therefore, stripping is an important step to reduce environmental pollution.

[0004] Stripping can effectively separate the metal and non-metal parts of the cable, making it easier to recycle and process later. This not only improves the efficiency of recycling, but also reduces the cost of recycling. At the same time, the metal part after stripping can directly enter the metal recycling process, and the non-metal part can enter the corresponding plastic or rubber recycling process, realizing the maximum utilization of resources.

[0005] In the Chinese patent with application number CN202323199715.8, a power cable stripper is mentioned, which includes a bottom plate, a fixed plate fixedly installed on one side of the top outer surface of the bottom plate, an arc-shaped plate one fixedly installed on the top of the fixed plate, and multiple support rods fixedly installed on the top outer surface of the bottom plate near the arc-shaped plate one. Place the end of the cable to be stripped on the outer surface of the arc-shaped plate one, then start the multiple electric push rods to move the arc-shaped plate two downward, so that the arc-shaped plate two contacts the outer surface of the cable. This can clamp cables of different sizes to prevent them from moving during stripping, which can cause danger. The opposite surfaces of the arc-shaped plate one and the arc-shaped plate two are provided with multiple balls, which can more conveniently push the cable to perform stripping work. At the same time, start the two hydraulic cylinders to move the blade to the cutting groove, so that the skin of the cable can be stripped when the cable is pushed.

[0006] However, the above-mentioned power cable stripper still has some shortcomings: after the power cable is put into the stripper, it still needs to be manually pushed towards the blade side, and the arc-shaped clamping plate and the arc-shaped plate cannot be adjusted in radius when facing power cables of different diameters, which cannot adapt to power cables of different diameters, and the scope of application is small. UTILITY MODEL CONTENTS

[0007] To address the problems existing in the prior art, this utility model provides a power cable stripper that can solve the problems that existing power cable strippers cannot push the cable and cannot adapt to power cables of different diameters.

[0008] A cable stripper includes a base, a drive unit disposed on one side of the base, and a push unit, a cut unit, and a fixing unit disposed sequentially on the base.

Each pushing roller has a bevel gear at both ends, and the bevel gears at both ends of each pushing roller mesh with the bevel gears of the adjacent pushing rollers in pairs. The driving unit can drive one of the pushing rollers to make all the pushing rollers rotate.

[0010] The push roller has a hollow structure and an air bladder is provided therein. The air bladder is provided with several protruding keys. The outer wall of the push roller is provided with key holes and inflation holes. When the air bladder is inflated, it expands and causes the protruding keys to pass through the key holes and protrude in a direction away from the axis of the push roller, and the protruding keys press against the cable. The rotation of the push roller can drive the cable to move in the direction of rotation.

[0011] The cutting section includes several supports disposed on one side of the frame and a blade fixedly disposed at one end of the supports.

[0012] The fixing part is located on the side of the cutting part away from the pushing part. The fixing part clamps the cable, so that the section of cable located between the fixing part and the pushing part is kept straight in the direction of movement.

[0013] Furthermore, each push roller is provided with a bearing seat on its left and right sides. The bearing seat has a shaft hole coaxial with the push roller, so that the rotation of the push roller coaxially can be set in the shaft hole of each pair of bearing seats. The push rollers are push rollers coplanar with the bearing seats, and the two pairs of push rollers are respectively in close contact with the cable.

[0014] Furthermore, the bracket is provided with a blade holder, which has a through groove into which a blade handle can be inserted. The axis of the through groove points perpendicularly to the axis of the cable. The blade is fixed on the blade handle, and the cutting surface of the blade is perpendicular to the cross-section of the cable.

[0015] Furthermore, the tool holder is a through-slot structure with an opening on the upper side. The opening is parallel to the through-slot channel, and a flange extends upward from both sides of the slot wall at the upper opening of the through-slot. A threaded hole is provided on the flange, the axis of the threaded hole is perpendicular to the flange, and a bolt and a matching nut are provided therein. After the bolt and nut are tightened, the through-slot clamps the tool handle, thereby fixing the tool handle.

[0016] Furthermore, the groove walls on both sides of the through groove are provided with first positioning holes, and the handle is provided with a plurality of second positioning holes arranged in an array along the handle axis. Positioning pins can be inserted into the positioning holes to fix the handle so that it will not rotate after being subjected to force.

[0017] Furthermore, the airbag and the raised key are integrally formed. The airbag is made of soft and elastic plastic, and the raised key is made of hard plastic. The two are joined together by interlocking. Metal teeth that increase friction are fixedly provided on the hard plastic, and the direction of the metal teeth is perpendicular to the direction of movement of the cable.

[0018] Furthermore, the fixing part includes several telescopic support rods vertically arranged on the top surface of the base, and the telescopic rods are located on the side of the bracket away from the pushing part. A roller plate is mounted on the telescopic support rod, the roller plate is parallel to the base, and several rollers are rotatably arranged on the roller plate to support the cable. Support brackets are also provided on the left and right sides of the telescopic bracket, and rollers are provided at the ends of the support brackets.

[0019] Furthermore, the drive unit consists of a motor and a reducer, the output shaft of the reducer is parallel to the base, and one of the push rollers is coaxially and fixedly connected to the output shaft of the reducer.

[0020] This invention has the following advantages: 1. Addressing the issue that existing cable strippers require manual cable pushing or additional devices, this invention uses a pushing roller to push the cable. The pushing roller has a hollow structure, and the air bladder inside causes the raised key to retract, allowing for adaptation to different wire diameters. It also increases the friction between the pushing roller and the cable. The transmission between the pushing rollers relies on bevel gears, requiring only one motor and reducer to drive the entire device. 2. Regarding the issue of adapting to different wire diameters, the blade position of this device can also be adjusted. Attached Figure Description

[0027] like Figure 1 As shown, a cable stripper includes a base 1, a drive unit disposed on one side of the base 1, and a push unit, a cutting unit, and a fixing unit disposed sequentially on the base 1.

[0028] The pushing unit includes a frame 31 vertically mounted on the base 1. Several coplanar pushing rollers 32 are rotatably mounted on the frame 31 and connected end to end in sequence. Each pushing roller 32 has a bevel gear 33 at both ends. The bevel gear 33 at both ends of each pushing roller 32 meshes with the bevel gear 33 of the adjacent pushing roller 32 in pairs. The driving unit can drive one of the pushing rollers 32 to make all the pushing rollers 32 rotate.

[0029] like Figure 3 As shown, the push roller 32 has a hollow structure and contains an air bladder 34. The air bladder 34 has several raised keys 36. The outer wall of the push roller 32 has keyholes 37 and inflation holes 35. An inflation valve 34 is fixedly installed in the inflation hole 35. After inflation (not shown in the figure) is completed, the inflation pipe can be removed, and the air valve will maintain the air pressure inside the air bladder 34. This is existing technology and will not be elaborated further. When the air bladder 34 is inflated, the expansion causes the raised keys 36 to pass through the keyholes 37 and protrude in a direction away from the axis of the push roller 32, pressing the raised keys 36 against the cable. Rotation of the push roller 32 can drive the cable to move in the direction of rotation. Preferably, as shown... Figure 1 As shown, each push roller 32 has a bearing seat 311 on its left and right sides. The bearing seat 311 has a shaft hole coaxial with the push roller 32, allowing the push roller 32 to rotate coaxially within the shaft hole of each pair of bearing seats 311. The push rollers 32 are coplanar with the bearing seats 311, and the two pairs of push rollers 32 respectively press against the cable, increasing the friction between the push roller 32 and the cable. Preferably, the airbag 34 and the raised key 36 are integrally formed. The airbag 34 is made of soft, elastic plastic, and the raised key 36 is made of hard plastic. The two are joined together. The raised key 36 is fixedly provided with metal teeth 361 to increase friction, and the direction of the metal teeth 361 is perpendicular to the direction of cable movement.

[0030] like Figure 2 As shown, the cutting section includes several supports 41 disposed on one side of the frame 31 and a blade 42 fixedly disposed at one end of each support 41. Preferably, as shown... Figure 2 As shown, a blade holder 412 is provided on the bracket 41. The blade holder 412 has a through groove into which a blade handle 43 can be inserted. The axis of the through groove points perpendicularly to the axis of the cable. The blade 42 is fixed on the blade handle 43, and the cutting surface of the blade 42 is perpendicular to the cross-section of the cable. Preferably, the blade holder 412 is a through groove structure with an upper opening 413. The opening 413 is parallel to the through groove channel, and a flange 414 extends upward from both sides of the groove wall at the upper opening 413. A threaded hole 415 is provided on the flange 414. The axis of the threaded hole 415 is perpendicular to the flange 414, and a bolt and a mating nut are provided therein. After the bolt and nut are tightened, the through groove clamps the blade handle 43, thereby fixing the blade handle 43. Preferably, the groove walls on both sides of the through groove are provided with first positioning holes 44, and the handle 43 is provided with a plurality of second positioning holes 45 arranged in an array along the axis of the handle 43. Positioning pins can be inserted into the positioning holes to fix the handle 43 so that it will not rotate after being subjected to force.

[0031] like Figure 4 As shown, the fixing part is located on the side of the cutting part away from the pushing part. The fixing part clamps the cable, so that the section of cable located between the fixing part and the pushing part is kept straight in the direction of movement.

[0032] Preferably, the fixing part includes several telescopic support rods 51 vertically arranged on the base 1, and the telescopic support rods 51 are located on the side of the bracket 41 away from the pushing part. A roller plate 52 is mounted on the telescopic support rod 51. The roller plate 52 is parallel to the base 1, and several rollers 53 are rotatably arranged on the roller plate 52 to support the cable. Supporting brackets 54 are also provided on the left and right sides of the telescopic bracket 41. A roller 55 is provided at the end of the supporting bracket 54. The roller 55 supports the cable, and the rotation direction of the roller 55 is the same as the movement direction of the cable.

[0033] Preferably, the drive unit consists of a motor and a reducer, the output shaft 2 of the reducer is parallel to the base 1, and one of the push rollers 32 is coaxially and fixedly connected to the output shaft 2 of the reducer.

[0034] It should be noted that the connection between the motor and the reducer is not shown in the diagram, and the motor needs to be connected to a power source not shown in the diagram to start.

[0035] The method of using this utility model is as follows: the cable is placed between the push rollers 32 from the side away from the cutting part, and the air inlet on the push roller 32 is inflated to make the air bag 34 expand, so that the protruding key 36 on the air bag 34 presses tightly against the outer wall of the cable. The protruding key 36 is also provided with metal teeth 361, which can increase the friction against the outer wall of the cable. After pressing, the motor is started to drive the reducer, so that the push roller 32, which is coaxially fixedly connected to the output shaft 2, rotates. The meshing bevel gears 33 make all the push rollers 32 rotate, thereby creating a thrust on the cable to move towards the cutting part. The position of the blade 42 of the cutting part can be adjusted according to the thickness of the cable sheath. The position of the support roller 55 of the fixing part and the height of the roller 53 plate 52 can be adjusted according to the actual situation.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
