Description

Technical Field

[0001] This utility model relates to the field of peeling machine technology, and in particular to a peeling device and a peeling machine thereof. Background Technology

[0002] Cable stripping devices, as a type of cable stripping processing equipment, are mainly used to remove a certain length of insulation layer from the surface of the cable, thereby exposing the conductor end and facilitating subsequent wiring operations. However, in current practical applications, determining the cable stripping position usually relies on hoisting or traction equipment to achieve positioning during cable delivery. This positioning method has certain limitations. Because the stripping device itself cannot actively adjust the stripping length, its flexibility during use is poor, thus adversely affecting stripping efficiency and wiring accuracy. It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0017] This utility model provides a peeling device and a peeling machine thereof. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] In the description of this utility model, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this utility model based on the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0019] Please see Figures 1 to 4 This utility model provides a peeling device, including a fixed frame 1, a lower blade assembly 2, and an upper blade assembly 3. A push-pull portion 4 is provided on the fixed frame 1 along its length. The lower blade assembly 2 is slidably connected to the fixed frame 1, and the output end of the push-pull portion 4 is drively connected to the lower blade assembly 2. The push-pull portion 4 is used to drive the lower blade assembly 2 to slide along the length of the fixed frame 1. The upper blade assembly 3 is disposed above the lower blade assembly 2, and a peeling groove is formed between the upper blade assembly 3 and the lower blade assembly 2. Component 3 is connected to the lower cutter assembly 2 via a lifting part 5. The lifting part 5 is used to drive the upper cutter assembly 3 to move up and down toward the lower cutter assembly 2. The push-pull part 4, in conjunction with the external wire feeding mechanism, forms a cable stripping length adjustment mechanism. First, the external wire feeding mechanism drives the cable to the predetermined stripping position. Then, the push-pull part 4 drives the upper cutter assembly 3 and the lower cutter assembly 2 to slide to the stripping start position according to the stripping length of the cable. This method effectively improves the flexibility of cable stripping and can effectively improve the stripping accuracy and efficiency of the cable.

[0020] In actual use, the cable is fed into the stripping device by a front-end cable feeding mechanism, such as a winch or traction device. The cable passes through the stripping groove formed by the lower cutter assembly 2 and the upper cutter assembly 3. At this time, the upper cutter assembly 3 is in a high position, the stripping groove is fully open, and the cable can pass smoothly. According to the required stripping length, the push-pull part 4 drives the entire lower cutter assembly 2 and the upper cutter assembly 3 to slide along the length of the fixed frame 1. The moving distance is the stripping length. After the lower cutter assembly 2 and the upper cutter assembly 3 have moved into place, the lifting part 5 drives the upper cutter assembly 3 to move downward, cutting into the cable insulation layer at the same time. After the upper cutter assembly 3 and the lower cutter assembly 2 are clamped, the push-pull part 4 starts again, driving the lower cutter assembly 2 to move backward or forward a certain distance. Since the cable is clamped and fixed by the traction device, the upper cutter assembly 3 and the lower cutter assembly 2 generate axial displacement relative to the cable, peeling the cut insulation layer from the conductor, completing the stripping. After peeling is completed, the lifting unit 5 drives the upper cutter head assembly 3 to rise and release the cable; the pushing and pulling unit 4 pushes the lower cutter head assembly 2 and the upper cutter head assembly 3 back to their initial positions, ready for the peeling action.

[0021] like Figures 1 to 4As shown, further, a sliding frame 6 is provided on the top of the fixed frame 1 along its length direction. The sliding frame 6 is slidably connected to the fixed frame 1, and the lower cutter head assembly 2 is disposed on the sliding frame 6. A first hinge seat 11 is provided at one bottom end of the fixed frame 1. The fixed end of the push-pull part 4 is hinged to the first hinge seat 11, and the output end of the push-pull part 4 is provided with a second hinge seat 41. A push-pull plate 61 is provided on the sliding frame 6 and hinged to the second hinge seat 41. The sliding frame 6 and the fixed frame 1 form a linear sliding pair. The sliding frame 6 can reciprocate along the length direction of the fixed frame 1. The lower cutter head assembly 2 is installed as a whole on the sliding frame 6. The displacement of the sliding frame 6 can directly determine the cable stripping length. By providing the first hinge seat 11 and the second hinge seat 41 as rotation fulcrums for the fixed end and the output end of the push-pull part 4, the small angular deviations caused by manufacturing, assembly or force can be automatically compensated, avoiding the problem of interference between the push-pull part 4 and the fixed frame 1 during operation.

[0022] It should be noted that the push-pull part 4 is an existing electric telescopic rod, cylinder, servo electric cylinder or other device with telescopic function. The specific structure and working principle are existing technologies and will not be described in detail here.

[0023] like Figures 1 to 4 As shown, further, a guide slider 12 is provided on the top of the fixing frame 1, and a groove 13 with an opening on one side is provided on the guide slider 12. The sliding frame 6 is slidably connected to the groove 13, and a cover plate 14 is detachably connected to the opening of the groove 13. The groove 13 is opened on one side of the guide slider 12, and the cross-section of the groove 13 is C-shaped. After the sliding frame 6 is inserted from the opening side of the groove 13, the opening is closed by the cover plate 14 to form a complete closed guide pair. When maintaining the lower cutter head assembly 2 or the upper cutter head assembly 3, the cover plate 14 can be removed by screws, clips or quick-release pins, so that the cover plate 14 and the guide slider 12 are detachably connected. During disassembly and assembly, it is not necessary to completely remove the sliding frame 6; simply loosening the cover plate 14 allows the sliding frame 6 to be pulled out from the side.

[0024] like Figures 1 to 4 As shown, the lifting part 5 further includes a lifting cylinder 51. The side of the lifting cylinder 51 near its output end is connected to the lower cutter head assembly 2 via a guide rod assembly 52. ​​The upper cutter head assembly 3 is slidably connected to the guide rod assembly 52, and the output end of the lifting cylinder 51 is drively connected to the upper cutter head assembly 3. The cylinder body of the lifting cylinder 51 is fixed on the lower cutter head assembly 2. The guide rod assembly 52, the lower cutter head assembly 2, and the lifting cylinder 51 form a gantry frame. The two ends of the upper cutter head assembly 3 are slidably engaged with the guide rod assembly 52 via linear bearings or copper sleeves, and are rigidly connected to the output end of the lifting cylinder 51.

[0025] In this embodiment, when in standby mode, the output end of the lifting cylinder 51 retracts, the upper cutter assembly 3 is located at the upper end of the guide rod assembly 52, and the stripping groove is fully open. When the upper cutter assembly 3 descends, the output end of the lifting cylinder 51 extends and pushes the upper cutter assembly 3 vertically down along the guide rod; the descent distance is precisely controlled by the cylinder stroke or an external limit switch. When it is necessary to clamp or cut into the cable, the upper and lower cutters together grip the cable, and the blades cut into the insulation layer to a set depth; at this time, the guide rod assembly 52 bears the radial cutting reaction force to ensure the parallelism of the upper and lower cutters.

[0026] like Figures 1 to 4 As shown, the lower cutter head assembly 2 further includes a lower cutter seat 21 and a lower stripping cutter 22 disposed on the lower cutter seat 21; the upper cutter head assembly 3 includes an upper cutter seat 31 and an upper stripping cutter 32 disposed on the upper cutter seat 31; a cable routing groove 23 is provided at one end of the lower cutter seat 21 near the lower stripping cutter 22; the lower cutter seat 21 and the upper cutter seat 32 are connected by the lifting part 5; the stripping groove is located between the lower stripping cutter 22 and the upper stripping cutter 32; the cable is horizontally fed in by the traction device, passes through the cable routing groove 23, the bottom of the cable is supported by the bottom surface of the cable routing groove 23, and its two sides are limited by the side walls of the cable routing groove 23 to ensure that the center line of the cable coincides with the center line of the cutter; the bottom of the side wall of the cable routing groove 23 allows the automatically falling insulation debris to fall off, and the cable routing groove 23 also allows for easy manual observation of the cut quality.

[0027] like Figures 1 to 4 As shown, further, the upper stripping tool 32 includes a first stripping blade 321, which is disposed at the end of the upper blade holder 31; the lower stripping tool 22 includes a second stripping blade 221, which is disposed at the end of the lower blade holder 21; the first stripping blade 321 is provided with a first groove opening towards the second stripping blade 221, and the second stripping blade 221 is provided with a second groove opening towards the first stripping blade 321. The first groove and the second groove are staggered along the cable feeding direction, and the first groove and the second groove surround to form the stripping groove; the first groove and the second groove are staggered back and forth along the cable feeding direction, and when they are aligned vertically, they form a staggered closed stripping groove. The edges of the two grooves interlock in a shearing manner, cutting the insulation layer in a ring shape. The shearing blade formed by the staggered groove produces a combined tearing and shearing effect on the insulation layer, so that the insulation layer is completely peeled off, avoiding damage to the conductor due to its diameter being smaller than the closed circular hole of the groove.

[0028] In use, the cable passes horizontally through the cable routing groove 23, with its centerline located between the first and second cutting grooves. The lifting cylinder 51 drives the upper cutting seat 31 to descend, and the first cutting groove first covers the upper half of the cable; after continuing to descend, the second cutting groove covers the lower half of the cable, and the edges of the two cutting grooves interlock in a shearing manner, cutting the insulation layer in a ring shape.

[0029] like Figures 1 to 4 As shown, further, the upper peeling knife 32 also includes a positioning pressure knife 322, which is movably connected to the upper knife holder 31 and is located inside the first peeling knife 321; the lower peeling knife 22 also includes a positioning knife holder 222, which has a first slot 223 that mates with the positioning pressure knife 322. The positioning knife holder 222 is disposed on the lower knife holder 21 and is located inside the second peeling knife 221. A first slot 223 adapted to the first peeling knife 321 is formed between the positioning knife holder 222 and the second peeling knife 221. The cable is placed on the positioning knife holder 222 for radial coarse positioning. In the initial stage of the descent of the lifting cylinder 51, the positioning pressure knife 322 first contacts the cable and presses it firmly on the positioning knife holder 222. At least part of the positioning pressure knife 322 is inserted into the first slot 223 to complete the axial and radial precise positioning. At this time, the lifting cylinder 51 continues to descend, and the first stripping knife 321 is inserted into the corresponding second slot 224. The first stripping knife 321 and the second stripping knife 221 are misaligned and engaged to cut the insulation layer. Then the push-pull part 4 drives the lower knife holder 21 to move axially as a whole to complete the stripping of the insulation layer. The positioning pressure knife 322 always presses the cable to prevent the conductor from slipping with the insulation layer.

[0030] like Figures 1 to 4 As shown, further, the upper tool holder 31 is provided with a lifting groove, and the positioning pressure knife 322 is slidably connected to the lifting groove. The top of the positioning pressure knife 322 is provided with a limiting part 323, which is located above the upper opening of the lifting groove. Both ends of the limiting part 323 are connected to the upper tool holder 31 through first elastic elements (not shown in the figure). The positioning pressure knife 322 can slide up and down along the lifting groove. The limiting part 323 at the top of the positioning pressure knife 322 is T-shaped, and the flange of the limiting part 323 is always located above the upper opening of the lifting groove to prevent the positioning pressure knife 322 from falling out as a whole. A first elastic element, such as a compression spring, tension spring, or disc spring, is hung at each of the left and right ends of the limiting part 323. The other end of the first elastic element is fixed to the upper surface of the upper tool holder 31 to form a floating pre-compression mechanism. The first elastic element provides variable clamping force. The thicker the wire diameter, the greater the retraction, and the greater the clamping force, thus realizing adaptive clamping.

[0031] When in use, the lifting cylinder 51 descends, and the positioning pressure knife 322 contacts the cable first; since the first elastic element is compressible, the positioning pressure knife 322 retracts relative to the upper knife seat 31 into the lifting groove, and the elastic force is converted into a clamping force, which presses the cable firmly on the positioning knife seat 222.

[0032] like Figures 1 to 4 As shown, further, the bottom sides of the positioning knife holder 222 are connected to the lower knife holder 21 by second elastic elements (not shown in the figure); the positioning knife holder 222 is placed on the horizontal support platform of the lower knife holder 21, and a second elastic element, such as a compression spring, disc spring or rubber pad, is provided on each of the left and right sides of the bottom; the lower end of the second elastic element is fixed to the lower knife holder 21, and the upper end is pressed against the bottom of the positioning knife holder 222 to form a floating support, so as to cooperate with the positioning pressure knife 322 to realize the adaptive adjustment of the clamping force and meet the clamping and positioning requirements of cables with different wire diameters.

[0033] This utility model also provides a peeling machine, including the peeling device described above.

[0034] In summary, the push-pull unit 4 and the external wire feeding mechanism constitute a cable stripping length adjustment mechanism. First, the external wire feeding mechanism drives the cable to the preset stripping position; then, the push-pull unit 4, according to the desired stripping length, moves the upper cutter assembly 3 and the lower cutter assembly 2 to the stripping start position. This method significantly improves the flexibility of cable stripping, thereby effectively increasing the stripping accuracy and efficiency.
