Cable stripping and pulling device

Abstract

This invention discloses a cable stripping and cutting device, including a base, and a stripping mechanism, a cutting mechanism, and a switching mechanism disposed above the base. After the stripping mechanism forms an annular cut on the outer layer of the cable, the switching mechanism switches the cutting mechanism to perform a scribing and cutting action on the outer layer of the cable. The stripping mechanism rotates and cuts along the circumferential direction of the outer layer of the cable, forming an annular cut on the outer layer of the cable, separating the stripped section from the retained section. Then, the cutting mechanism scribes and cuts along the axial direction of the outer layer of the cable in the stripped section, forming a tear opening in the axial direction of the stripped section. The outer layer of the stripped section is then torn off along the tear opening, which can easily peel off the outer layer of the cable, solving the problem that it is not easy to peel off the outer layer of large-size cables / cable outer layer materials / cable outer layer thickness.

Description

[0001] This invention relates to the field of cable equipment technology, and specifically to a cable stripping and cutting device. Background Technology

[0002] Cables come in a variety of specifications. For some large-diameter cables, due to the large outer diameter, the material of the outer layer (when the material is hard, the outer layer of the cable has a large adhesive force with the inside of the cable), or the thickness of the outer layer wall, it is difficult to directly peel off the outer layer of the cable using existing stripping mechanisms. Therefore, it is necessary to improve the existing stripping mechanisms and stripping processes. Summary of the Invention

A second bevel gear that cooperates with the first bevel gear is fixedly installed at the adjustment end of the rotary adjustment rod and the adjustment end of the sliding adjustment rod.

[0041] The above technical solution involves a rotary stripping mechanism that rotates and cuts the outer layer of the cable in a circumferential direction, creating an annular cut on the outer layer to separate the stripped section from the retained section. A scribing mechanism then scribes and cuts the outer layer of the stripped section along its axial direction, creating a tear opening. The outer layer of the stripped section is then torn off along this tear opening, allowing for easy stripping of the cable's outer layer. This solves the problem of difficulty in stripping large-size cables due to their outer layer material or wall thickness. A switching mechanism ensures that the rotary stripping mechanism and the scribing mechanism operate in opposite directions, guaranteeing operational stability. Attached Figure Description

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0056] Please see Figure 1As shown in Figure 12, the cable stripping and cutting device is used for stripping and cutting the outer layer of the cable. It includes a horizontally placed base 10 and a stripping mechanism 12 located above the base 10. The stripping mechanism 12 rotates and cuts the outer layer of the cable in a circumferential direction along the outer periphery of the cable to form an annular cut 11 on the outer periphery of the cable. The stripping mechanism 12 cuts a cut of a certain depth into the outer layer of the cable, that is, it cuts from the outer surface of the cable to the inner surface, without cutting the second layer of the cable. The outer layer of the cable is divided along the axial direction from the cut.

[0057] And a scribing mechanism 14 that scribing cuts along the axial direction of the cable from the outer periphery of the cable outer layer to form a tear opening 13 on the outer surface of the cable outer layer axially; the scribing mechanism 14 scribing at least one tear opening 13 from the surface of the cable outer layer along the axial direction of the cable, the tear opening 13 being located on the section of the outer layer that needs to be peeled off from the cable, the tearing depth of the tear opening 13 being consistent with the thickness of the cable outer layer, that is, the thickness from the outer surface to the inner surface of the cable outer layer, in order to facilitate the subsequent peeling of the cable outer layer that needs to be peeled off from the cable, the tear opening 13 preferably extends from the annular cut 11 all the way to the end of the cable outer layer that needs to be peeled off.

[0058] A switching mechanism 15 is provided to switch the working states of the stripping mechanism 12 and the scriber mechanism 14. After the stripping mechanism 12 forms an annular cut 11 on the outer layer of the cable, the switching mechanism 15 switches the scriber mechanism 14 to perform a scriber cutting action on the outer layer of the cable. By switching the stripping mechanism 12 and the scriber mechanism 14 through the switching mechanism 15, the interference between the two mechanisms is avoided. After the stripping mechanism 12 completes its action, the scriber mechanism 14 is switched to the working position, applying a force to the axial direction of the cable, causing the cable to move in its axial direction. The scriber mechanism 14 then performs a scriber cutting action along the outer layer of the cable, forming a tear 13 on the section of the cable that needs to be stripped. Of course, the entire scriber device can also be retracted to achieve relative movement of the cable in its axial direction.

[0059] In this application, the annular cut 11 formed by the stripping mechanism 12 on the outer circumferential surface of the cable is a closed cut perpendicular to the cable axis and surrounding the outer circumferential surface of the cable; the tearing opening 13 formed by the axial stripping mechanism 14 on the outer surface of the cable is a straight opening parallel to the cable axis along the outer surface of the cable; that is, the annular cut 11 and the tearing opening 13 are arranged perpendicularly from the projection of the cable diameter direction; the starting point of the tearing opening 13 formed by the stripping mechanism 14 on the outer surface of the cable is at the annular cut 11, and the ending point is at the end of the outer layer of the cable to be stripped. This combination of annular cut 11 and straight opening is the optimal implementation method, which facilitates better cutting between the outer layer of the cable to be stripped and the outer layer of the cable to be retained, facilitates the formation of the tearing opening 13 on the outer layer of the cable to be stripped, and facilitates the subsequent tearing of the outer layer of the cable to be stripped from the cable through the combination of cut and opening.

[0060] In this application, the stripping mechanism 12 includes a stripping blade assembly 16 that moves towards the outer circumferential surface of the cable along the cable diameter direction to strip the cable or moves away from the outer circumferential surface of the cable to remove the stripping. The stripping blade assembly 16 performs circumferential cutting on the outer layer of the cable. The scribing mechanism 14 includes a scribing blade assembly 17 that moves towards the outer circumferential surface of the cable along the cable diameter direction to scribe or moves away from the outer circumferential surface of the cable to remove the scribing. The scribing blade assembly 17 performs axial scribing on the outer layer of the cable.

[0061] In this application, a first support portion 18 and a second support portion 19 are fixedly arranged at intervals on the base 10; the first and second support portions are plate-shaped supports vertically mounted on the base 10; a rotating disk 20 is rotatably mounted in the middle of the first support portion 18 via a bearing; a switching mechanism 15 is arranged between the inner side of the rotating disk 20 and the second support portion 19; a rotary peeling knife assembly 16 and a slicing knife assembly 17 are arranged on the outer center sides of the rotating disk 20, forming an upper and lower arrangement in the accompanying drawings; the upper one is the slicing knife assembly 17 and the lower one is the rotary peeling knife assembly 16.

[0062] Specifically, a conduit 21 for cable to pass through is provided between the second support 19 and the rotating disk 20. One end of the conduit 21 is rotatably mounted in the middle of the second support 19 via a bearing and extends outward from the second support 19. The other end is fixedly connected to the middle of the rotating disk 20 via a connecting block 22. In this way, the conduit 21 and the rotating disk 20 can rotate between the first support 18 and the second support 19.

[0063] Specifically, the conduit 21 has a stripping slot 23 for the stripper assembly 16 and a slicing slot 24 for the slicing blade assembly 17. The front end of the stripper assembly 16 faces the stripping slot 23, and the front end of the slicing blade assembly 17 faces the slicing slot 24. After the cable is inserted into the conduit 21, the stripper assembly 16 can be inserted into the stripping slot 23 to strip the outer layer of the cable at that location, and similarly, the slicing blade assembly 17 can be inserted into the slicing slot 24 to slice the outer layer of the cable.

[0064] Specifically, the second support 19 is provided with a rotary drive mechanism that drives the cable tube 21 and drives the rotating disk 20 to rotate around the axis of the cable tube 21. The drive mechanism includes a motor 25, a first gear 26, a second gear 27, and a first transmission belt 28. The motor 25 is fixedly mounted on the outside of the second support 19, and the output end of the motor 25 extends through the second support 19 into the inside of the second support 19. The first gear 26 is mounted on the output end of the motor 25, and the second gear 27 is mounted on the cable tube 21. The first transmission belt is located between the first gear 26 and the second gear 27 for transmission. During the stripping process, the first gear 26 on the motor 25 drives the second gear 27 to rotate through the first transmission belt, and at the same time drives the cable tube 21 to rotate. Since the rotation of the cable tube 21 can drive the rotating disk to rotate, the stripping blade assembly 16 located outside the rotating disk 20 can rotate circumferentially around the cable in the cable tube 21.

[0065] In this application, the switching mechanism 15 includes a switching drive 29, a rotary stripping connecting arm 30, a slicing connecting arm 31, and a switching drive mechanism. One end of the rotary stripping connecting arm 30 is connected to the rotary stripping blade assembly 16, and the other end cooperates with the switching drive 29. One end of the slicing connecting arm 31 is connected to the slicing blade assembly 17, and the other end cooperates with the switching drive 29. The switching drive mechanism is connected to the switching drive 29 and provides driving force to the switching drive 29, i.e., drives the switching drive 29 to switch between the switching drive 29 and the rotary stripping connecting arm 30 and the slicing connecting arm 31. Through the cooperation of the switching drive 29 with the rotary stripping connecting arm 30 and the slicing connecting arm 31, the rotary stripping blade assembly 16 moves closer to the outer periphery of the cable, while the slicing blade assembly 17 moves away from the outer periphery of the cable, or the rotary stripping blade assembly 16 moves away from the outer periphery of the cable, while the slicing blade assembly 17 moves closer to the outer periphery of the cable, thereby achieving the switching between rotary stripping and slicing actions.

[0066] In this specific implementation, a peeling slider 32 and a sweeping slider 33 are slidably mounted on the inner side of the rotating disk 20 along the radial direction of the rotating disk 20 via a slide rail. The peeling slider 32 and the sweeping slider 33 are located on both sides of the center of the rotating disk 20, and the peeling slider 32 and the sweeping slider 33 can move along the radial direction of the rotating disk 20 respectively. One end of the peeling connecting arm 30 is equipped with a first rolling element 34 that cooperates with the switching drive 29. The middle part of the peeling connecting arm 30 is fixedly connected to the peeling slider 32, and the other end of the peeling connecting arm 30 is fixedly connected to the peeling knife assembly 16. One end of the sweeping connecting arm 31 is equipped with a second rolling element 35 that cooperates with the switching drive 29. The middle part of the sweeping connecting arm 31 is fixedly connected to the sweeping slider 33, and the other end of the sweeping connecting arm 31 is fixedly connected to the sweeping knife assembly 17. The first rolling element 34 and the second rolling element 35 are rollers mounted on the connecting arm.

[0067] In this specific implementation, the switching drive component 29 is a hollow cylindrical sleeve, which is sleeved on the tubing 21. The outer wall of the tubing 21 and the inner wall of the switching drive component 29 are slidably fitted using a sliding groove and slider mechanism. The switching drive component 29 can reciprocate along the axial direction of the tubing 21 on its outer surface. One side of the switching drive component 29 is provided with a peeling switching surface that cooperates with the first rolling element 34. The peeling switching surface includes a first driving surface 36 axially arranged along the outer peripheral surface of the switching drive component 29 and a second driving surface 37 forming a bevel from the outer peripheral surface of the switching drive component 29 toward the middle of the switching drive component 29. The other side of the switching drive component 29 is provided with a... The second rolling element 35 cooperates with a shifting switching surface, which includes a third driving surface 38 arranged axially along the outer peripheral surface of the switching drive member 29, a fourth driving surface 39 arranged axially along the switching drive member 29 and lower than the third driving surface 38, and an inclined fifth driving surface 40 connecting the third driving surface 38 and the fourth driving surface 39. The axial distance between the fourth driving surface 39 and the fifth driving surface 40 on the switching drive member 29 corresponds to the first driving surface 36, while the axial distance between the second driving surface 37 on the switching drive member 29 corresponds to the third driving surface 38. The second driving surface 37 and the fifth driving surface 40 have the same inclination direction on the switching drive member 29.

[0068] The following describes the switching process of the switching drive 29 on the slicing knife assembly 17 and the spin stripper assembly 16, based on the relationship between the rolling elements and the corresponding switching surfaces: When the switching drive 29 moves towards the rotating disk 20, and the first rolling element 34 is on the first driving surface 36 and the second rolling element 35 is on the fourth driving surface 39, the slicing knife assembly 17 is in the slicing position, and the spin stripper assembly 16 is away from the outer layer of the cable. During the retraction of the switching drive 29, when the second rolling element 35 is on the fifth driving surface 40 and the first rolling element 34 is on the first driving surface 36, the slicing knife assembly 17 retracts from the slicing position. When the first rolling element 34 rolls inward along the second driving surface 37 and the second rolling element 35 is on the third driving surface 38, the spin stripper assembly 16 moves closer to the outer layer of the cable, gradually entering the spin stripping position. This achieves the switching action between the spin stripper assembly 16 and the slicing knife assembly 17.

[0069] In this specific implementation, the switching drive mechanism provides reciprocating sliding for the switching drive component 29 on the conduit 21 to achieve the following switching process: when the switching drive mechanism drives the switching drive component 29 to slide along the conduit 21 toward the rotating disk 20, it drives the stripping blade assembly 16 away from the outer circumference of the cable and the slicing blade assembly 17 toward the outer circumference of the cable; when the switching drive mechanism drives the switching drive component 29 to slide along the conduit 21 away from the rotating disk 20, it drives the stripping blade assembly 16 toward the outer circumference of the cable and the slicing blade assembly 17 away from the outer circumference of the cable. Specifically, the switching drive mechanism includes a drive plate 41, a drive motor 42, and a drive screw 43. The drive plate 41 is rotatably mounted on the switching drive component 29 via bearings. The drive screw 43 is mounted on the rotating end of the drive motor 42. A threaded transmission is formed between the drive screw 43 and the drive plate 41. When the drive motor 42 rotates forward and backward, it drives the drive plate 41 to move back and forth through the drive screw 43, thereby driving the reciprocating movement of the switching drive component 29. To ensure the smooth movement of the drive plate 41, four guide posts are fixedly installed between the first support part 18 and the second support part 19. The guiding direction of the guide posts is the same as the axial direction of the conduit 21. The guide posts pass through the drive plate 41 to form a sliding fit for guidance.

[0070] In the specific implementation of this application, in order to ensure that the rolling element always rolls in contact with the corresponding driving surface, the peeling connecting arm 30 and the sliding connecting arm 31 are located on both sides of the center of the rotating disk 20; a tension elastic element 44 is provided between the peeling connecting arm 30 and the sliding connecting arm 31 to pull them towards the middle position in the mating direction; the tension elastic element 44 is a tension spring, one end of which is hooked on a bolt on one side of the peeling connecting arm 30 and the other end of which is hooked on a bolt on one side of the sliding connecting arm 31, forming a pulling force on the peeling connecting arm 30 and the sliding connecting arm 31 towards the middle; between the peeling connecting arm 30 and the rotating disk 20, and between the sliding connecting arm 31 and the rotating disk 20, a support elastic element 45 is provided with the opposite force to the tension elastic element 44. The supporting elastic element 45 is a spring. For example, the supporting elastic element 45 on one side of the rotary stripping connecting arm 30 is arranged as follows: a base block 46 is fixedly installed on the rotary disk 20, and an L-shaped pressure block 47 is fixedly installed on the rotary stripping connecting arm 30. One end of the supporting elastic element 45 rests on the L-shaped pressure block 47, and the other end is in the mounting hole of the base block 46, so that the supporting elastic element 45 is pressed between the L-shaped pressure block 47 and the base block 46. The supporting elastic element 45 on one side of the sliding connecting arm 31 is arranged in the same way.

[0071] In this specific implementation, the base 10 is provided with a clamping mechanism for clamping the cable when the stripping mechanism 12 rotates and strips the cable; a third support part 48 is fixedly installed on the base 10 on one side of the stripping mechanism 12, and the clamping mechanism is assembled on the third support part 48; specifically, the clamping mechanism includes a bearing plate 49, four sliding clamping blocks 50, a guide plate 51, a drive plate 52, a clamping drive mechanism, and a cable guide tube 53; the bearing plate 49 is fixedly assembled on one side of the third support part 48, one side of the guide plate 51 is fixedly assembled with the bearing plate 49, and the drive plate 52 is located on the other side of the guide plate 51; the four sliding clamping blocks 50 are slidably assembled on one side of the bearing plate 49 in a disengaged or engaged manner, and between the four sliding clamping blocks 50 A space is formed to clamp the cable. A sliding transmission component 54 is fixedly installed on the back of each sliding clamp 50, and the sliding transmission component 54 extends to a certain length. A sliding guide groove 55 is provided on the guide plate 51 for the sliding transmission component 54 to pass through. The drive plate 52 is located on one side of the guide plate 51. A drive groove 56 is provided on the drive plate 52 to cooperate with the sliding transmission component 54 and drive the sliding transmission component 54 to slide within the stroke of the sliding guide groove 55, so as to realize the separation or engagement of the four sliding clamps 50. When the drive plate 52 rotates, it drives the sliding transmission component 54 to move within the stroke of the sliding guide groove 55 through the drive groove 56, so as to drive the four sliding clamps 50 to form a separation or engagement action, thereby clamping or releasing the cable. The cable conduit 53 passes through the center of the bearing plate 49, the guide plate 51, and the drive plate 52. The cable enters from one end of the cable conduit 53 and enters between the four sliding clamps 50. The axis of the cable conduit 53 is coaxial with the axis of the cable tube 21. The conduit 53 is fixedly connected to the guide plate 51, and the drive plate 52 is rotatably mounted on the conduit 53 via a bearing.

[0072] Specifically, the drive disk 52 is driven to rotate by a wire clamping drive mechanism. The wire clamping drive mechanism includes a drive wheel 57, a driven wheel 58, a transmission belt 59, and a wire clamping motor 60. The wire clamping motor 60 is mounted on the base 10, the drive wheel 57 is mounted on the output end of the wire clamping motor 60, and the transmission belt 59 is arranged between the drive wheel 57 and the driven wheel 58 for transmission. The driven wheel 58 is fixedly connected to the drive disk 52. Thus, when the wire clamping motor 60 rotates in both directions, the driving force is transmitted to the drive disk 52 in sequence through the drive wheel 57, the transmission belt 59, and the driven wheel 58, so that the drive disk 52 can rotate in both directions, thereby realizing the clamping and loosening of the cable by the sliding clamp 50.

[0073] Specifically, to facilitate the sequential introduction of cables into conduit 53 and conduit 21, a guide tube 61 is provided on one side of the base 10 at the third support part 48, forming a coaxial connection with conduit 53. The guide tube 61 is provided with a tapered guide opening 62. The guide tube 61 is fixedly mounted on a bracket 63, and the lower end of the bracket 63 is fixed to the base 10.

[0074] Specifically, the slicing knife assembly 17 includes a slicing knife housing 64, a slicing knife 65, a slicing adjustment block 66, and a slicing adjustment rod 67. The slicing knife housing 64 is fixedly assembled with the slicing connecting arm 31 by screws, forming an installation space within the slicing knife housing 64. The slicing adjustment block 66 is slidably assembled in the installation space within the slicing knife housing 64. The slicing knife 65 is fixedly assembled to the slicing adjustment block 66 by screws, and the front end of the slicing knife 65 is a slicing cutting edge that extends out of the slicing knife housing 64. One end of the slicing adjustment rod 67 extends into the slicing knife housing 64 and is threadedly connected to the slicing adjustment block 66, while the other end is positioned for slicing. Outside the blade housing 64, serving as an adjustment end, when this end is rotated, the slicing adjustment rod 67 can drive the slicing adjustment block 66 to slide up and down inside the slicing blade housing 64, thereby adjusting the length of the cutting edge of the slicing blade 65 extending into the slicing blade housing 64, changing the slicing depth on the outer layer of the cable, and adapting to different slicing depth requirements; the cutting edge of the slicing blade 65 is arranged along the axial direction of the cable to facilitate better slicing of the outer layer of the cable; a retaining sleeve 68 is fixedly installed above the slicing blade housing 64, through which the slicing adjustment rod 67 passes, ensuring the rotational stability of the slicing adjustment rod 67.

[0075] In this application, a position adjustment mechanism for adjusting the slicing knife assembly 17 is also included. The position adjustment mechanism is installed on the outside of the third support portion 48 and specifically includes a position adjustment seat 69, an adjustment push rod 70, and a reset elastic element 71. The position adjustment seat 69 is fixedly installed on the outside of the third support portion 48, and has an installation space. The reset elastic element 71 is arranged in this installation space. The adjustment push rod 70 is slidably mounted on the adjustment seat, and a first bevel gear 72 is fixedly installed at the front end of the adjustment push rod 70. A [missing information - likely a gear or component] is fixedly installed at the rear end of the adjustment push rod 70. The adjusting rotary part 73 is used to operate the adjusting push rod 70; the adjusting end of the peeling adjusting rod and the adjusting end of the sliding adjusting rod 67 are fixedly provided with a second bevel gear 74 that cooperates with the first bevel gear 72; when the adjusting rotary part 73 is pushed, the reset elastic member 71 is compressed and stored, the first bevel gear 72 and the second bevel gear 74 mesh, the adjusting rotary part 73 is rotated, and the peeling adjusting rod is adjusted; when the pushing force of the adjusting rotary part 73 is removed, under the action of the reset elastic member 71, the adjusting push rod 70 drives the first bevel gear 72 and the second bevel gear 74 to separate and reset. Specifically, a movable block 75 is provided inside the position adjusting seat 69. The movable block 75 is fixedly mounted on the adjusting push rod 70. A position detection contact 76 is installed on the movable block 75. A positioning detector 77 that cooperates with the position detection contact 76 is also installed on the position adjusting seat 69. When the position detection contact 76 extends into the positioning detector 77, the positioning detector 77 detects positioning information, indicating that the first bevel gear 72 and the second bevel gear 74 are meshed. The adjusting rotating part 73 can be rotated to adjust the sliding adjusting rod 67. Specifically, the reset elastic member 71 is pressed between the inner wall of the position adjusting seat 69 and the movable block 75. When the external thrust on the adjusting rotating part 73 is removed, the reset elastic member 71... When the adjusting push rod 70 and the moving block 75 are moved outward to reset, the first bevel gear 72 and the second bevel gear 74 separate, and the position detection contact 76 separates from the position detector 77. In order to prevent misoperation, a limit cylinder 78 is also provided. The extension end of the limit cylinder 78 is equipped with a limit block 79. When the slicing knife assembly 17 does not need to be adjusted, the limit cylinder 78 extends, and the limit block 79 extends into the position adjusting seat 69 and blocks the moving block 75 on one side. When the adjusting rotating part 73 is pushed from the outside, the moving block 75 cannot move. When the slicing knife assembly 17 needs to be adjusted, the limit cylinder 78 is withdrawn, the limit block 79 is retracted, the blockage on the moving block 75 is removed, and the operation can be performed. Furthermore, in order to ensure the smooth movement of the adjusting push rod 70 and improve the accuracy of the movement, a guide seat 80 is fixedly installed on the inner side of the third support part 48. The adjusting push rod 70 passes through the guide seat 80 and is guided by the guide seat 80. A positioning rod 81 is fixedly installed on the moving block 75, and a positioning hole 82 is opened on the guide seat 80. When the moving block 75 moves, the positioning rod 81 is inserted into the positioning hole 82 to prevent the first bevel gear 72 from moving out of position.

[0076] In this application, a position detector 83 is provided on the first support part 18 to detect the position of the slicing knife assembly 17. That is, a detection part corresponding to the position detector 83 is installed on the adjustment end of the slicing adjustment rod 67 to cooperate with the position detector 83 to detect the position. When the position detector 83 detects that the slicing knife assembly 17 is in place, it means that the second bevel gear 74 is in the meshing position after the first bevel gear 72 has traveled, and the position adjustment mechanism can be operated.

[0077] In this application, the rotary stripper assembly 16 includes a rotary stripper housing 84, a rotary stripper 85, a rotary stripper adjusting block 86, and a rotary stripper adjusting rod 87. The rotary stripper housing 84 is fixedly assembled with the rotary stripper connecting arm 30. The rotary stripper adjusting block 86 is slidably assembled inside the rotary stripper housing 84. The rotary stripper 85 is fixedly assembled on the rotary stripper adjusting block 86. The front end of the rotary stripper 85 extends out of the rotary stripper housing 84. One end of the rotary stripper adjusting rod 87 extends into the rotary stripper housing 84 and is threadedly connected to the rotary stripper adjusting block 86. The other end is outside the rotary stripper housing 84 and serves as the adjusting end. The cutting edge of the front end of the rotary stripper 85 is arranged along the circumference of the cable. The main difference between the rotary stripper assembly 16 and the slicing knife assembly 17 is the different arrangement direction of the front cutting edge; their specific structures will not be described in detail here. In addition, when it is necessary to adjust the rotary stripper assembly 16, rotate the rotary stripper assembly 16 to the position detector position, so that the rotary stripper assembly 16 is in the position adjustment mechanism position, and then the extension length of the front cutting edge of the rotary stripper 85 of the rotary stripper assembly 16 can be adjusted. By adjusting the rotary stripper assembly 16 and the slicing knife assembly 17, the requirements for rotary stripping and slicing of the outer layer of cables of different thicknesses can be met.

[0078] In this application, a limiting rod 88 is installed at the end of the conduit 21, which is inserted into the conduit 21. The limiting rod 88 has a scale, and a locking screw 89 locks the limiting rod 88 and the conduit 21 together. In use, the cable enters the conduit 21 through the guide tube 61 and the cable threading tube 53, and rests on the limiting rod 88. The scale on the limiting rod 88 indicates the length of the outer layer that needs to be stripped from the cable, which is the axial distance between the limiting surface of the limiting rod and the stripping blade assembly 16. A cover 90 is installed on the base 10. Except for the end of the limiting rod 88, the locking screw 89, the adjusting rotating part 73, and the guide tube 61, which are exposed outside the cover, the entire device is protected by the cover 90. A control panel 91 is installed on the upper part of the cover 90 for operating the device.

[0079] The section of cable to be stripped passes through a guide tube and a conduit, then enters the conduit. A clamping mechanism holds the cable in place to ensure stability during the stripping process. A stripping blade assembly is used to create a ring-shaped cut on the outer layer of the cable. A switching mechanism resets the stripping blade assembly, and the slicing blade assembly enters the slicing position. The clamping mechanism releases its clamping force, but maintains a pre-clamped state (the clamping mechanism is in contact with the outer surface of the cable, but without creating a clamping force that prevents axial movement), preventing rotation during the slicing process. Force is applied from the outside to pull the cable out. The slicing blade assembly creates a tear along the stripped section of the cable from the ring-shaped cut. The outer layer of the cable is then torn off along this tear. During cable extraction, force is applied only along the cable's axis, without rotational force, ensuring the tear is created axially along the cable's outer layer. If the tear formed during cable extraction is not along the axial direction of the outer layer of the cable due to the cable's rotation, then it can be considered feasible to facilitate the peeling of the outer layer of the cable.
