Description

Technical Field

[0001] The present invention relates to the technical field of cable connection, and more specifically, it relates to a rapid wire stripping device for communication cables. Background Art

[0002] Communication cables can be divided into single-core cables and multi-core cables according to the number of core wires. A single-core cable mainly consists of a single conductive core wire and an insulating protective layer wrapped around it. Among them, the conductive core wire usually selects metal materials with excellent electrical conductivity such as copper and aluminum, and the insulating layer plays the role of effectively isolating the core wire from the external environment, thereby preventing the occurrence of electric leakage and the generation of signal interference. In actual applications, when connecting a single-core communication cable, it is necessary to first cut the cable to a length that meets the requirements, and then perform wire stripping on both ends of the cable for subsequent connection.

[0003] Within the scope of the prior art, the cutting and wire stripping operations of single-core communication cables mostly rely on manual labor. Specifically, the operator first manually cuts the cable to the specified length with a tool, and then uses a special wire stripping tool to perform wire stripping operations on both ends of the cable. However, this manual operation method has obvious disadvantages, not only with low operation efficiency, but also with a cumbersome and complex operation process. Especially when facing a large number of cable wire stripping tasks, the above problems are more prominent. Summary of the Invention

Detailed implementation manners

[0032] In the present invention, unless otherwise specified, the orientations such as "upper" and "lower" generally refer to the directions shown in the drawings, or to the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left" and "right" generally refer to the left and right shown in the drawings; "inner" and "outer" refer to the inner and outer of the contour of each component itself. However, the above orientation terms are not used to limit the present invention.

[0033] Embodiment: Please refer to Figures 1-15 the structural schematic diagram. The present invention provides the following technical solution: A rapid wire stripping device for communication cables, including a machine base 1, a chute base 2 is provided on the machine base 1, two sliding plates 3 are symmetrically and slidably provided on the chute base 2, two sliders 4 are slidably provided on each sliding plate 3 in an up-and-down symmetrical manner, connection blocks 5 are connected between the two upper sliders 4 and between the two lower sliders 4, a cutting knife 6 for cutting communication cables is provided on the side surface of the connection block 5, a semi-circular clamping opening 401 for clamping the communication cable is provided on the slider 4, and a wire stripping knife 7 for cutting the cable insulation layer is provided on the side of the slider 4 and located on the side of the slider 4 facing the cutting knife 6. Among them, the wire stripping knife 7 has a semi-circular notch, and the radius of the semi-circular notch of the wire stripping knife 7 is equal to the radius of the communication cable core. When the two wire stripping knives 7 approach the communication cable at the same time, the blades of the wire stripping knives 7 cut off the insulation layer of the communication cable, and the communication cable core is located in the semi-circular notches of the two wire stripping knives 7, so the wire stripping knives 7 have no influence on the core of the communication cable.

[0034] Specifically, place the communication cable between the two sliders 4 on each sliding plate 3 and align the communication cable with the semi-circular clamping opening 401 of the slider 4. When the sliders 4 move towards the communication cable at the same time, the semi-circular clamping openings 401 of the two sliders 4 on each sliding plate 3 clamp the communication cable at the same time, and the wire stripping knives 7 cut off the insulation layer of the communication cable. At the same time, the sliders 4 drive the connection blocks 5 to approach the communication cable at the same time, so the cutting knife 6 cuts off the communication cable.

[0035] Sliding columns 8 are connected between the two upper sliders 4 and between the two lower sliders 4. Slide seats 9 are provided on the sides of the two sliding plates 3. A connecting plate 10 is slidably provided on the two slide seats 9 together. A first spring 11 is connected between the connecting plate 10 and the slide seats 9. A clamping block 12 is provided on the side of the connecting plate 10 close to the sliding column 8. Two inclined chutes 1201 are provided on the clamping block 12 in an up-and-down symmetrical manner, and the two inclined chutes 1201 respectively form a sliding fit with the two sliding columns 8. A contact strip 13 is provided on the opposite side of the connecting plate 10 to the clamping block 12.

[0036] There are two side plates 14 provided on the machine base 1. A wire stripping motor 15 is provided on one side plate 14. A main shaft 17 is rotatably provided on the two side plates 14. Two transmission wheels of the transmission mechanism 16 are respectively provided on the rotating shaft of the wire stripping motor 15 and the main shaft 17. A cam 18 for driving the contact bar 13 is provided in the middle of the main shaft 17.

[0037] Among them, the transmission mechanism 16 is composed of two transmission wheels and a transmission belt. The transmission belt is wound around the transmission belt together. When one transmission wheel rotates, power is transmitted through the transmission belt to make the other transmission wheel rotate.

[0038] Specifically, start the wire stripping motor 15, transmit power through the transmission mechanism 16, and drive the main shaft 17 to rotate. The main shaft 17 drives the cam 18 to rotate synchronously. During the process of the cam 18 rotating from 45 degrees to 90 degrees, the cam 18 drives the contact bar 13 to move towards the slider 4. The moving contact bar 13 drives the connecting plate 10 and the clamping block 12 to move synchronously. Two inclined chutes 1201 on the clamping block 12 respectively drive the two sliding columns 8 to move towards the communication cable. Therefore, the slider 4 moves towards the communication cable at the same time.

[0039] A support rod 19 is provided on the main shaft 17. A roller 20 is provided at the end of the support rod 19. An inclined pressure block 21 that cooperates with the roller 20 is provided on the first slide plate 3. An inclined surface is provided on the starting inclined pressure block 21. The roller 20 is used to roll on the inclined pressure block 21. Two traction seats 22 are provided on the machine base 1. Traction components are provided on both of the two traction seats 22. A second spring 23 is connected between the second slide plate 3 and the second traction seat 22.

[0040] Specifically, during the process of the cam 18 rotating from 180 degrees to 225 degrees, the roller 20 rolls on the inclined surface of the inclined pressure block 21, driving the inclined pressure block 21 and the two slide plates 3 to move towards the second traction seat 22. The second spring 23 is compressed. Each slider 4 moves synchronously with the slide plate 3. The two sliders 4 on the first slide plate 3 strip the insulating layer of the communication cable. During the process of the cam 18 rotating from 225 degrees to 270 degrees, the cam 18 first separates from the contact bar 13. The first spring 11 provides elastic force to make the connecting plate 10 and the clamping block 12 move away from the sliding column 8. Two inclined chutes 1201 on the clamping block 12 respectively drive the two sliding columns 8 to move away from the communication cable. Therefore, the slider 4, the cutting knife 6 and the wire stripping knife 7 are all separated from the communication cable. Subsequently, the roller 20 separates from the inclined surface of the inclined pressure block 21. The second spring 23 provides elastic force to make each slide plate 3 move to the original state.

[0041] The base 1 is provided with a traction motor 24. The rotating shaft of the traction motor 24 is coaxially and slidably connected with a middle rotating shaft 25. Specifically, the traction motor 24 and the middle rotating shaft 25 are connected by a sliding spline, and the middle rotating shaft 25 is rotatably arranged on a rotating support plate 26. The rotating support plate 26 is fixedly arranged above the base 1. A first bevel gear 27 is arranged on the middle rotating shaft 25. A third spring 28 is sleeved outside the middle rotating shaft 25. The two ends of the third spring 28 are respectively in contact with the rotating support plate 26 and the first bevel gear 27. A circular push plate 29 in contact with the cam 18 is arranged at the end of the middle rotating shaft 25.

[0042] The traction assembly includes a second bevel gear 30 meshing with the first bevel gear 27. The second bevel gears 30 of the two traction assemblies are respectively located on both sides of the first bevel gear 27. The second bevel gear 30 is fixedly arranged at one end of a side rotating shaft 31. The side rotating shaft 31 is rotatably arranged on the corresponding side plate 14. A third bevel gear 32 is arranged at the other end of the side rotating shaft 31. A fourth bevel gear 33 meshing with the side of the third bevel gear 32 is arranged. The fourth bevel gear 33 is fixedly arranged at one end of a secondary rotating shaft 34. The secondary rotating shaft 34 is rotatably arranged on the base 1 and is rotatably arranged in the corresponding traction seat 22. The secondary rotating shaft 34 passes through the traction seat 22, and a lower runner 35 for pulling the cable is arranged at the other end of the secondary rotating shaft 34. A groove for clamping the communication cable is arranged on the cylindrical surface of the lower runner 35.

[0043] The traction assembly further includes a first gear 36 fixedly arranged on the secondary rotating shaft 34. A pressure block 37 is slidably arranged in the traction seat 22. An upper rotating shaft 38 is rotatably arranged in the pressure block 37. An upper runner 40 cooperating with the lower runner 35 is arranged at one end of the upper rotating shaft 38. A groove for clamping the communication cable is arranged on the cylindrical surface of the upper runner 40. A second gear 39 meshing with the first gear 36 is arranged at the other end of the upper rotating shaft 38. A screw 41 is screwed into the top of the traction seat 22. A fourth spring 42 is connected between the screw 41 and the pressure block 37.

[0044] In the original state, that is, when the cam 18 is at the zero-degree state, adjust the screwing degree of the screws 41 of the two sets of traction components, so as to adjust the tightness of the fourth spring 42, that is, adjust the downward pressure exerted by the fourth spring 42 on the pressing block 37. Sequentially place the communication cable between the upper runner 40 and the lower runner 35 of the first and second sets of traction components. The fourth spring 42 provides elastic force to clamp the communication cable by the grooves of the upper runner 40 and the lower runner 35. At the same time, when the cam 18 is at the zero-degree state, the cam 18 contacts the circular push plate 29, and the third spring 28 is compressed, so that the first bevel gear 27 and the second bevel gear 30 are in the meshed state. The traction motor 24 drives the middle rotating shaft 25 to rotate. The middle rotating shaft 25 drives the first bevel gear 27 to rotate synchronously. The first bevel gear 27 drives the second bevel gears 30 of the two sets of traction components to rotate synchronously. The power is transmitted through the side rotating shafts 31, the third bevel gears 32, the fourth bevel gears 33, and the auxiliary rotating shafts 34 of each set of traction components, so that the lower runners 35 of the two sets of traction components rotate synchronously. The power is transmitted through the first gear 36 and the second gear 39, so the upper runners 40 rotate synchronously. Therefore, the two sets of traction components pull the communication cable forward, and the communication cable moves along the direction from the first set of traction components to the second set of traction components.

[0045] During the process of the cam 18 rotating from zero degree to forty-five degrees, the cam 18 disengages from the circular push plate 29. The third spring 28 provides elastic force to move the middle rotating shaft 25 and the circular push plate 29 away from the second bevel gear 30, that is, the first bevel gear 27 and the second bevel gear 30 are separated, and the second bevel gears 30 of the two sets of traction components no longer rotate, so the communication cable no longer advances. During the process of the cam 18 moving from two hundred and seventy degrees to three hundred and sixty degrees (zero degree), the cam 18 contacts the circular push plate 29 again, so it drives the circular push plate 29 to move towards the second bevel gear 30, and makes the first bevel gear 27 mesh with the second bevel gear 30 again.

[0046] A third gear 44 and a fourth gear 45 are rotatably provided on the second side plate 14. The third gear 44 and the fourth gear 45 are meshed with each other. A fifth gear 46 is meshed beside the fourth gear 45. The fifth gear 46 is fixedly provided on the side rotating shaft 31 of the second set of traction components. A sector gear 43 for driving the third gear 44 is provided on the main shaft 17.

[0047] During the process of the cam 18 rotating from ninety degrees to one hundred and eighty degrees, the first bevel gear 27 is still separated from the second bevel gear 30. The sector gear 43 meshes with the third gear 44. The power is transmitted through the third gear 44 and the fourth gear 45, so that the side rotating shaft 31 of the second set of traction components rotates. Therefore, the upper runner 40 and the auxiliary rotating shaft 34 of the second traction component rotate, and the cut communication cable is pulled out. At the same time, during this process, since the two sliders 4 on the second slide plate 3 clamp the cut communication cable, and the corresponding two stripping knives 7 cut the insulating layer at the tail end of the cut communication cable, the insulating layer at the tail end of the cut communication cable is automatically peeled off.

[0048] A support plate 47 is provided on the machine base 1. A fixed wire cylinder 48 is provided on the support plate 47. A flared opening is provided at the entrance of the fixed wire cylinder 48. The flared opening at the entrance of the fixed wire cylinder 48 is aligned with the centers of the lower runner 35 and the upper runner 40 of the first set of traction components. The exit of the fixed wire cylinder 48 is aligned with the centers of the two sliders 4 on the first slide plate 3.

[0049] Specifically, when placing the communication cable, the communication cable is placed into the fixed wire cylinder 48. Therefore, after cutting the communication cable, the lower runner 35 and the upper runner 40 of the first set of traction components pull the communication cable forward, facilitating the entry of the new communication cable between the respective sliders 4.

[0050] A support plate 49 is provided on the machine base 1. A telescopic wire cylinder 50 is provided on the support plate 49. A spring five 51 is connected between the two telescopic joints of the telescopic wire cylinder 50. The two telescopic joints of the telescopic wire cylinder 50 are in sliding connection. A flared opening is provided at the entrance of the telescopic wire cylinder 50. The flared opening at the entrance of the telescopic wire cylinder 50 is aligned with the centers of the two sliders 4 on the second slide plate 3. The exit of the telescopic wire cylinder 50 is aligned with the centers of the lower runner 35 and the upper runner 40 of the second set of traction components.

[0051] Specifically, when placing the communication cable, the communication cable is placed into the telescopic wire cylinder 50. When the slide plate 3 moves towards the second chute seat 2, the two sliders 4 on the second slide plate 3 contact the flared opening at the entrance of the telescopic wire cylinder 50, causing the telescopic joints of the telescopic wire cylinder 50 to contract and the spring five 51 to be compressed. When the slider 4 returns to its original state, the spring five 51 provides elastic force to cause the telescopic joints of the telescopic wire cylinder 50 to return to their original state. After the cut communication cable is pulled out, the telescopic wire cylinder 50 facilitates the entry of the new communication cable between the lower runner 35 and the upper runner 40 of the second set of traction components.

[0052] Working principle: In the original state, that is, when the cam 18 is in the zero-degree state, adjust the screwing degree of the screws 41 of the two sets of traction components, thereby adjusting the tightness of the spring four 42, that is, adjusting the downward pressure exerted by the spring four 42 on the pressure block 37. Place the cables on the communication cable reel into the upper runner 40 and the lower runner 35 of the first and second sets of traction components in sequence. The spring four 42 provides elastic force to clamp the communication cable with the grooves of the upper runner 40 and the lower runner 35. At this time, the communication cable is placed between the two sliders 4 on each slide plate 3 and is aligned with the semi-circular clamping openings 401 of the sliders 4. At the same time, place the communication cable into the fixed wire cylinder 48 and the telescopic wire cylinder 50. And when the cam 18 is in the zero-degree state, the cam 18 contacts the circular push plate 29, and the spring three 28 is compressed, causing the bevel gear one 27 and the bevel gear two 30 to be in a meshing state; the slide plate 3 is located at a position away from the second traction seat 22.

[0053] Start the traction motor 24. The traction motor 24 drives the middle rotating shaft 25 to rotate. The middle rotating shaft 25 drives the first bevel gear 27 to rotate synchronously. The first bevel gear 27 drives the second bevel gears 30 of the two groups of traction assemblies to rotate synchronously. The power is transmitted through the side rotating shafts 31, the third bevel gears 32, the fourth bevel gears 33, and the auxiliary rotating shafts 34 of each group of traction assemblies, so that the lower rotating wheels 35 of the two groups of traction assemblies rotate synchronously. The power is transmitted through the first gear 36 and the second gear 39, so the upper rotating wheel 40 rotates synchronously. Therefore, the two groups of traction assemblies pull the communication cable forward, and the communication cable moves along the direction from the first group of traction assemblies to the second group of traction assemblies.

[0054] When the two groups of traction assemblies pull the communication cable to move the required length, start the stripping motor 15. The power is transmitted through the transmission mechanism 16 to drive the main shaft 17 to rotate. The main shaft 17 drives the cam 18 to rotate synchronously.

[0055] During the process of the cam 18 rotating from 0 degree to 45 degrees, the cam 18 disengages from the roller 20. The third spring 28 provides elastic force to move the middle rotating shaft 25 and the circular push plate 29 in the direction away from the second bevel gear 30, that is, the first bevel gear 27 and the second bevel gear 30 are separated, and the second bevel gears 30 of the two groups of traction assemblies no longer rotate, so the communication cable no longer moves forward.

[0056] During the process of the cam 18 rotating from 45 degrees to 90 degrees, the cam 18 drives the contact strip 13 to move in the direction of the slider 4. The contact strip 13 drives the connecting plate 10 and the clamping block 12 to move synchronously. The two inclined chutes 1201 on the clamping block 12 respectively drive the two sliding columns 8 to move in the direction of the communication cable, so the slider 4 moves in the direction of the communication cable at the same time. The semi-circular clamping mouths 401 of the two sliders 4 on each sliding plate 3 clamp the communication cable at the same time. The slider 4 drives the connecting block 5 to move closer to the communication cable at the same time, so that the cutting knife 6 cuts off the communication cable. At the same time, the two stripping knives 7 corresponding to the first group of sliding plates 3 cut off the insulating layer at the head end of the communication cable that has not been cut off, and the two stripping knives 7 corresponding to the second group of sliding plates 3 cut off the insulating layer at the tail end of the communication cable that has been cut off.

[0057] During the process of the cam 18 rotating from 90 degrees to 180 degrees, the sector gear 43 meshes with the third gear 44. The power is transmitted through the third gear 44 and the fourth gear 45 to make the side rotating shaft 31 of the second group of traction assemblies rotate. Therefore, the upper rotating wheel 40 and the auxiliary rotating shaft 34 of the second traction assembly rotate to pull out the cut-off communication cable. At the same time, during this process, since the two sliders 4 on the second sliding plate 3 clamp the insulating layer of the cut-off communication cable, the insulating layer at the tail end of the cut-off communication cable is automatically peeled off.

[0058] When the cam 18 rotates from 180 degrees to 225 degrees, the roller 20 rolls on the inclined surface of the inclined pressure block 21, driving the inclined pressure block 21 and the two slide plates 3 to move towards the second traction seat 22. The second spring 23 is compressed, and each slider 4 moves synchronously with the slide plate 3. Since the two sliders 4 on the first slide plate 3 clamp the insulating layer of the uncut communication cable, the insulating layer at the head end of the uncut communication cable is automatically peeled off.

[0059] When the cam 18 rotates from 225 degrees to 270 degrees, the cam 18 first separates from the contact strip 13. The first spring 11 provides elastic force to move the connecting plate 10 and the clamping block 12 away from the sliding column 8. The two inclined chutes 1201 on the clamping block 12 respectively drive the two sliding columns 8 to move away from the communication cable. Therefore, the slider 4, the cutting knife 6 and the wire stripping knife 7 are all separated from the communication cable. Subsequently, the roller 20 separates from the inclined surface of the inclined pressure block 21, and the second spring 23 provides elastic force to move each slide plate 3 to its original state.

[0060] When the cam 18 rotates from 270 degrees to 360 degrees (0 degrees), the cam 18 comes into contact with the roller 20 again, so it drives the circular push plate 29 to move towards the bevel gear 30, making the bevel gear 27 mesh with the bevel gear 30 again.

[0061] Therefore, during one rotation of the cam 18, the cutting knife 6 automatically cuts the communication cable and automatically peels off the insulating layer at the head end of the uncut communication cable and the insulating layer at the tail end of the cut communication cable. Therefore, during the periodic operation of the cam 18, the continuous communication cable is automatically cut, and the two ends of the communication cable are automatically wire-stripped. During this process, only the periodic start and stop of the wire-stripping motor 15 need to be controlled, and the traction motor 24 does not need to stop rotating, thus reducing the complexity of the control system.

[0062] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
