Description

Technical Field

[0001] The present invention relates to the technical field of cable processing equipment, in particular to an automatic cable stripping machine. Background Art

[0002] Cable stripping is a crucial step in the recycling process, driven by factors including increased economic value, environmental compliance, efficient resource utilization, and ease of subsequent processing. The core value of cables lies in their inner metal conductors (such as copper and aluminum), while the outer insulation materials (such as plastic and rubber) have lower recycling value. Selling unstripped cables directly will result in them being classified as "mixed waste." Furthermore, the melting of insulated cables produces smoke and residue, reducing the purity of the metal. Furthermore, the outer insulation material of cables also poses certain hazards. If directly incinerated (e.g., by fire), materials like PVC release highly toxic gases such as dioxins and hydrogen chloride, seriously polluting the environment. They are difficult to degrade in landfills, leading to long-term contamination of soil and groundwater. After cable stripping, the metal conductors can be remelted into high-purity raw materials for use in the manufacture of new cables or industrial materials. Insulation materials (such as PE and rubber) can be recycled into plastic products (such as pipes and floor mats) through processes like crushing and granulation, reducing resource waste.

[0003] In the existing cable stripping equipment, during the cable stripping operation, the cables that have not been stripped are mostly controlled by the unwinding machine, so that the cables can smoothly enter the stripping equipment, and the metal conductors left after the stripping process are mostly controlled by the winding machine to achieve the purpose of smoothly storing the metal conductors. Most of the equipment uses a cutter to separate the external insulating material (such as plastic, rubber) from the internal metal conductor (copper, aluminum, etc.). However, after the cutter cuts the insulating sheath on the outer surface, the insulating sheath and the internal metal conductor are prone to adhesion. The electric cutter is not convenient for peeling off the adhered part. The adhered part is likely to affect the stripping quality and is more likely to affect the winding operation of the metal conductor, reducing the stripping efficiency. Therefore, the present invention provides an automatic cable stripping machine to meet the needs. Summary of the Invention

[0004] In view of the above problems, the present invention provides an automatic cable stripping machine.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an automatic cable stripping machine, comprising a cutting outer ring and a first guide ring and a second guide ring arranged on the front and rear sides of the cutting outer ring and coaxially distributed therewith, wherein the cutting outer ring is provided with a plurality of cutting units equidistantly distributed along a circular track, and the cable on which the stripping operation has not been performed passes through the second guide ring and the inside of the cutting outer ring, and after the cutting unit performs the cutting operation, the metal conductor with the outer skin stripped moves into the inside of the first guide ring.

[0006] The first guide ring is provided with two groups of synchronously movable positioning roller groups 1, a driving frame 1 installed on the positioning roller group 1, and a stripping sleeve installed on the driving frame 1. The second guide ring is provided with multiple groups of positioning roller groups 2 equidistantly distributed along a circular track, and a driving frame 2 installed on the positioning roller group 2. Both the driving frame 1 and the driving frame 2 are provided with power units that can drive them to move.

[0007] When the power unit drives the two sets of positioning roller group 1 and the multiple sets of positioning roller group 2 to move toward the metal conductor cable and the cable respectively, the two stripping sleeves are spliced into a funnel-shaped structure. As the cable moves, the insulating outer sheath of the cable is cut by the cutting unit and moved out to the outside of the stripping sleeve, and the metal conductor is located inside the stripping sleeve.

[0008] Furthermore, the cutting unit includes a driving ring arranged outside the cutting outer ring, and the inner and outer surfaces of the driving ring are provided with tooth blocks evenly distributed along the circumferential trajectory. The tooth blocks located on the inner surface of the driving ring are engaged with multiple synchronous gears evenly distributed along the circumferential trajectory. The synchronous gears are all connected to a synchronous sleeve that can rotate synchronously with the first synchronous shaft through a first synchronous shaft, and the first synchronous shaft is installed on the inner wall of the cutting outer ring.

[0009] A pair of mounting grooves are provided on the surface of the synchronous sleeve along its diameter direction, and cutting blades are provided in the mounting grooves. As the driving ring rotates, multiple sets of synchronous gears and the synchronous sleeve rotate synchronously until the cutting blades face the central axis position of the cutting outer ring.

[0010] Furthermore, the inner wall of the outer cutting collar is connected to a coaxially distributed inner cutting collar via a bracket, and both the outer cutting collar and the inner cutting collar are provided with a channel for exposing the cutting blade.

[0011] Furthermore, a first driving gear is provided on the outside of the cutting outer ring, the first driving gear is engaged with the tooth block on the outer surface of the driving ring, and a driving component that can control its rotation is provided on the first driving gear.

[0012] Furthermore, the first guide ring and the second guide ring are both provided with a linkage external gear ring of the same specifications, and the first guide ring and the second guide ring are both installed with a second drive gear that meshes with the linkage external gear ring. The two second drive gears are connected by the same linkage shaft, and the end of the linkage shaft is provided with a drive component that can drive it to rotate.

[0013] Furthermore, the power unit is arranged on the outside of the first guide ring or the second guide ring, and each group of power units includes a parallel distributed transmission gear 1, a transmission gear 2 and a second synchronization shaft connecting the transmission gear 1 and the transmission gear 2. The second synchronization shaft is installed on the outer wall of the first guide ring or the second guide ring, and the transmission gear 1 located on the outside of the first guide ring and the second guide ring is meshed with the linkage external gear ring on the outside thereof.

[0014] Furthermore, the first guide ring and the second guide ring are respectively provided with channels for accommodating the exposure of the drive frame 1 and the drive frame 2. The drive frame 1 and the drive frame 2 are both provided with racks meshing with the transmission gear 2. As the transmission gear 1 and the transmission gear 2 rotate synchronously, the drive frame 1 and the drive frame 2 can respectively carry the positioning roller group 1 and the positioning roller group 2 to move toward the metal conductor and the cable.

[0015] Furthermore, the first guide ring and the second guide ring are both provided with a limit frame outside which can accommodate the movement of the drive frame one or the drive frame two. When the positioning roller group one and the positioning roller group two move toward the cable and the metal conductor respectively, the drive frame one and the drive frame two both move along the distribution direction of the limit frame.

[0016] In summary, the technical effects and advantages of the present invention are as follows:

[0017] 1. The present invention can effectively prevent the insulating outer layer of the metal conductor from sticking to the metal conductor after cutting by setting the stripping sleeve. As the metal conductor moves, the insulating outer layer can be quickly scraped off the metal conductor, which improves the stripping quality while ensuring the smoothness of the cable and metal conductor during movement.

[0018] 2. During the stripping process, the present invention allows for rapid switching of multiple cutting blade positions, enabling cutting operations at different points on the insulation sheath. This improves the comprehensiveness of the cutting operation and allows the insulation sheath to be quickly separated from the metal conductor. This also reduces the time required to replace the cutting blades at each point, ensuring optimal cutting performance and further enhancing the quality of cable cutting.

[0019] 3. During the stripping process, the present invention's first and second positioning rollers move synchronously to precisely position the metal conductor and cable, effectively preventing any shaking during cable payout and metal conductor winding that could affect the cutting process, thereby improving cutting accuracy. This reduces the time required for point-by-point positioning and enhances operational efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: A cable automatic stripping machine, such as Figure 1 As shown, the automatic cable stripping machine comprises a cutting outer collar 1, and first and second guide rings 2 and 3, coaxially arranged in front and rear of the cutting outer collar 1. The cutting outer collar 1 houses multiple sets of cutting units equidistantly spaced along a circular trajectory. During the cable stripping process, unstripped cables are mostly controlled by a pay-off machine, allowing them to smoothly enter the automatic cable stripping machine. The remaining metal conductors after stripping are mostly controlled by a reel to smoothly receive them. With the assistance of the pay-off and reel, tension is applied to the cable during the stripping process, allowing it to move smoothly and be stripped.

[0033] Therefore, during the actual use of the automatic cable stripping machine, the cable that has not been stripped needs to pass through the second guide ring 3 and enter the inner side of the cutting outer ring 1. After the cutting unit on the inner side of the cutting outer ring 1 performs the cutting operation, the metal conductor with the outer skin stripped is moved into the inner side of the first guide ring 2 until the metal conductor is centrally wound.

[0034] In order to maintain the stability of the cable and the metal conductor stripped after cutting on the inner side of the second guide ring 3 and the first guide ring 2, as shown in FIG. Figure 2 、 Figure 3 As shown, the first guide ring 2 is equipped with two sets of synchronously movable positioning roller groups 1 21, a driving frame 1 22 mounted on positioning roller group 1 21, and a stripping sleeve 23 mounted on driving frame 1 22. The second guide ring 3 is equipped with multiple sets of positioning roller groups 2 31 equidistantly distributed along a circular track, and a driving frame 2 32 mounted on positioning roller group 2 31. In order to enable the synchronous movement of positioning roller groups 1 21 and 2 31 to position the cable and the metal conductor stripped after cutting, each driving frame 1 22 and driving frame 2 32 is equipped with a power unit that can drive them to move.

[0035] When the power unit drives the two sets of positioning roller group 1 21 and the multiple sets of positioning roller group 2 31 to move toward the metal conductor cable and the cable respectively, the two stripping sleeves 23 are spliced into a funnel-shaped structure. As the cable moves, the insulating outer sheath of the cable is cut by the cutting unit and moved out to the outside of the stripping sleeve 23, and the metal conductor is located on the inside of the stripping sleeve 23.

[0036] The setting of the stripping sleeve 23 can effectively prevent the insulating outer layer of the metal conductor from sticking to the metal conductor after cutting. As the metal conductor moves, the insulating outer layer can be quickly scraped off the metal conductor, effectively avoiding the phenomenon of the metal conductor moving stuck caused by the insulating outer layer sticking to the surface of the metal conductor. While ensuring the stripping quality, it also ensures the smoothness of the movement of the cable and the metal conductor.

[0037] Example 2, based on Example 1, Figure 7 、 Figure 8 As shown, the cutting unit includes a driving ring 12 arranged outside the cutting outer collar 1, and the inner and outer surfaces of the driving ring 12 are provided with tooth blocks equidistantly distributed along the circumferential trajectory. The tooth blocks located on the inner surface of the driving ring 12 are engaged with multiple synchronous gears 13 equidistantly distributed along the circumferential trajectory. The synchronous gears 13 are all connected to a synchronous sleeve 15 that can rotate synchronously with the first synchronous shaft 14. The first synchronous shaft 14 is installed on the inner wall of the cutting outer collar 1.

[0038] Reference Figure 9 The surface of the synchronous sleeve 15 is provided with a pair of mounting grooves 151 along its diameter. Each mounting groove 151 is equipped with a cutting blade 16. When the cable is located inside the outer cutting collar 1, as the drive ring 12 rotates, the multiple sets of synchronous gears 13 and the synchronous sleeve 15 rotate synchronously until the cutting blades 16 are aligned with the central axis of the outer cutting collar 1. As the cable moves, the multiple cutting blades 16, which are aligned with the cable insulation, cut the cable insulation at different points on the outer sheath, improving the comprehensiveness of the cutting operation and allowing the insulation to be quickly separated from the metal conductor.

[0039] Furthermore, since two cutting blades 16 are mounted on the surface of the synchronous sleeve 15 based on the arrangement of the mounting grooves 151, after the cutting operation is completed, if it is found that the blades are wearing out the cable insulation, the drive ring 12 can be controlled to rotate, causing the multiple sets of synchronous gears 13 and the synchronous sleeve 15 to rotate again until the other cutting blade 16 on the surface of the synchronous sleeve 15 is aligned with the central axis of the outer cutting ring 1, thereby performing the cutting operation on the cable. During the operation, the time of replacing the cutting blades 16 at each point can be reduced, the cutting effect of the cutting blades 16 is guaranteed, and the cutting quality of the cable is further improved.

[0040] During the initial installation of the cable, in order to facilitate the positioning of the cable, a cutting inner ring 11 coaxially distributed therewith is connected to the inner wall of the cutting outer ring 1 through a bracket. The cable needs to be placed inside the cutting inner ring 11. In order to ensure the smooth implementation of the cutting operation, channels are provided on the cutting outer ring 1 and the cutting inner ring 11 for exposing the cutting blade 16.

[0041] In order to enable the drive ring 12 to rotate smoothly and to facilitate switching the position of the cutting blade 16, a first drive gear 17 is provided outside the cutting outer collar 1. The first drive gear 17 is engaged with the tooth block on the outer surface of the drive ring 12, and the first drive gear 17 is provided with a drive component that can control its rotation.

[0042] Example 3: Figure 4-6 As shown, in Example 1, based on the setting of positioning roller group 1 21 and positioning roller group 2 31, during the cable cutting operation, the metal conductor after the outer skin is cut and the cable that has not been cut can be positioned at the front and rear sides of the cutting unit respectively, so as to maintain the stability of the cable during the movement inside the cutting unit, avoid the cable from shaking during the movement, and facilitate the cutting unit to cut the cable accurately and stably.

[0043] Furthermore, based on Example 1, the first and second guide rings 2 and 3 are each provided with a linkage external gear ring 4 of the same specifications. Furthermore, each of the first and second guide rings 2 and 3 is equipped with a second drive gear 8 that meshes with the linkage external gear ring 4. The two second drive gears 8 are connected by a common linkage shaft 9, the end of which is provided with a drive assembly that drives the second drive gears 8 to rotate. When the drive assembly is in operation, the linkage external gear ring 4 on the first and second guide rings 2 and 3 rotates synchronously due to the connection between the second drive gear 8 and the linkage external gear ring 4.

[0044] To move positioning roller set 1 21 and positioning roller set 2 31 toward the metal conductor and cable, a power unit is located outside the first guide ring 2 or the second guide ring 3. Each power unit includes a parallel transmission gear 1 5 and transmission gear 2 7, as well as a second synchronization shaft 6 connecting transmission gear 1 5 and transmission gear 2 7. The second synchronization shaft 6 is mounted on the outer wall of the first guide ring 2 or the second guide ring 3. The transmission gear 1 5 located outside the first guide ring 2 or the second guide ring 3 meshes with the linkage outer gear ring 4 outside of the first guide ring 2 or the second guide ring 3. When the linkage outer gear ring 4 rotates, the transmission gear 1 5 located outside the first guide ring 2 or the second guide ring 3 also rotates synchronously.

[0045] Since the first guide ring 2 and the second guide ring 3 are respectively provided with channels for accommodating the exposure of the drive frame 1 22 and the drive frame 2 32, the drive frame 1 22 and the drive frame 2 32 are both provided with racks meshing with the transmission gear 2 7. As the transmission gear 1 5 and the transmission gear 2 7 rotate synchronously, the drive frame 1 22 and the drive frame 2 32 can respectively carry the positioning roller group 1 21 and the positioning roller group 2 31 to move toward the metal conductor and the cable.

[0046] Therefore, during the cutting process, positioning roller assembly 1 21 and positioning roller assembly 2 31 can move synchronously to precisely position the metal conductor and cable, ensuring that the cable before and after stripping are aligned on the same straight path. This provides high positioning accuracy, effectively preventing the shaking caused by the cable unwinding and the metal conductor winding from affecting the cutting operation. This prevents the cutting blade 16 from cutting the metal conductor or incompletely cutting the insulation, thereby improving the accuracy of the cutting operation. Furthermore, it reduces the time required for point-by-point positioning operations, improving operational efficiency.

[0047] A limit frame 10 is provided outside the first guide ring 2 and the second guide ring 3 to accommodate the movement of the drive frame 1 22 or the drive frame 2 32. The setting of the limit frame 10 can maintain the stability of the drive frame 1 22 and the drive frame 2 32. When the positioning roller group 1 21 and the positioning roller group 2 31 move toward the cable and the metal conductor respectively, the drive frame 1 22 and the drive frame 2 32 both move along the distribution direction of the limit frame 10, thereby avoiding the drive frame 1 22 and the drive frame 2 32 from shaking during the movement.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
