Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and in particular to a cutting device for non-stop disc replacement for medium and high voltage cable processing. Background Art

[0002] In the traditional cable processing process, when a reel of cable is processed, it is usually necessary to stop the machine to replace the reel. With the continuous improvement of industrial automation and intelligent levels, the technology of non-stop reel replacement is also constantly developing and improving. For example, some advanced equipment has realized more intelligent control systems and more efficient reel replacement methods, further improving production efficiency and product quality. The non-stop reel replacement technology for cable processing not only solves the problems of low production efficiency, unstable product quality, high labor intensity and increased production costs under traditional methods, but also promotes the automation and intelligent development of the cable processing industry.

[0003] The non-stop reel-changing and cutting operation in medium and high voltage cable processing is an efficient and continuous cable production method that aims to reduce production interruptions and improve production efficiency. During the cable processing process, when a reel of cable material is about to run out, it can be quickly replaced with a new cable reel without interrupting the production process, and the cutting operation can continue. The main purpose of this operation method is to reduce production interruption time and improve production efficiency and product quality.

[0004] When the cable is cut without stopping the machine to change the reel, when the cutting knife is used for a long time and contacts with the cable, the cutting surface of the cutting knife will be worn and the cutting knife will no longer be sharp. When the cutting knife continues to cut the cable in this state, the cutting knife will not be sharp enough and the cutting knife will not be able to cut the cable, so the whole equipment needs to be stopped to replace the cutting knife before continuing the subsequent processing and cutting operation, which reduces the efficiency of the whole equipment. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention cooperates with two groups of cutting knives and two groups of matching clamping knives arranged inside the placement seat. In the working state, when the cutting knives cannot smoothly cut the cables, the cutting knives and the matching clamping knives can be driven to replace the old ones with new ones. The cables are cut by the replaced new cutting knives, thereby avoiding the disadvantage that the equipment needs to be shut down before the cutting knives can be replaced when the cutting knives are severely worn. At the same time, the normal operation of the equipment will not be affected during the entire replacement process, thereby improving the processing efficiency of the overall equipment;

[0020] 2. At the same time, after the cutting knife and the matching clamping knife are replaced, the matching clamping knife and the replaced cutting knife will limit the entire cable again, which is helpful for the cable to be better limited and fixed after the cutting knife is replaced and in the subsequent shearing process, and enhance the shearing effect of the cutting knife on the cable. Subsequently, under the thrust of the hydraulic rod, the cutting knife is driven to move toward the matching clamping knife. Then, under the cooperation of the cutting knife and the matching clamping knife, a shearing force is formed on the cable. Compared with traditional single-knife cutting, this shearing force is easier to cut the cable, and the shearing processing efficiency of the cable is improved. In addition, the above-mentioned shearing force can also effectively disperse the impact force of the cable on the cutting knife and the matching clamping knife, reduce the impact damage to the knife during the cutting process, increase the service life of the cutting knife and the matching clamping knife, and shorten the frequency of tool replacement;

[0021] 3. During the entire process of replacing the cutting knife, the position of the placement seat is detected by the set laser sensor. When it is found that the placement seat pauses and stays at the current position, the signal is transmitted to the console, and the console controls the start motor to drive the square shaft to rotate to avoid the wrong replacement of the cutting knife. At the same time, one end of the cut cable will be clamped by the elastic clamp, so that the entire cable can be more conveniently wound onto the new take-up reel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention. Example 1

[0034] See also Figures 1 to 9 , which is the first embodiment of the present invention, provides a technical solution: a cutting device for medium and high voltage cable processing without stopping the machine to change the disc, comprising a control console 1 and a rotating disc 2 arranged on the control console 1, the control console 1 is used to control the rotating disc 2 arranged thereon to rotate, so as to facilitate the replacement of the take-up disc 31 with a new one after the take-up disc 31 is full of cables during cable processing, and at the same time, the control console 1 controls the driving of the electronic components arranged on the rotating disc 2, so as to facilitate the cutting knife 49 to cut the cable;

[0035] A polyhedral rotating shaft 3 is symmetrically arranged on the rotating disk 2, and a take-up drum 31 is arranged on the polyhedral rotating shaft 3. The polyhedral rotating shaft 3 is used to rotate under the control of the control console 1. During the rotation process, the take-up drum 31 placed on the polyhedral rotating shaft 3 is driven to take up the cable. When the staff finds that the take-up drum 31 that is taking up the cable is about to be full of cable, the rotating disk 2 is controlled to rotate through the control console 1, and the new take-up drum 31 is adjusted to the waiting position for taking up the cable. Then, the cable is cut by the cutting component 4, so that it is wound on the new take-up drum 31, and the cable reel operation without stopping is completed. The cutting component 4 is symmetrically arranged on the rotating disk 2, and the cutting component 4 is used to cut the cable during the reel change process;

[0036] The cutting assembly 4 includes a swing arm 41 disposed on the rotating disk 2. The swing arm 41 is a square swing rod. When in use, the swing arm 41 is driven by a driving shaft disposed on the rotating disk 2 to swing 90 degrees. When the swing arm 41 changes from being perpendicular to the rotating disk 2 to being parallel to the rotating disk 2, a hydraulic rod 46 disposed inside the swing arm 41 drives a cutting knife 49 to cut the clamped cable.

[0037] A support plate 42 is arranged on one side of the swing arm 41, and a semi-ring matching plate 43 is arranged on the support plate 42. The semi-ring matching plate 43 is used to stabilize the cable during the cutting process when the cutting knife 49 cuts the cable. At the same time, the matching clamping knife 45 arranged on the support plate 42 stabilizes the cable on both sides of the cutting knife 49 to prevent the cable from being twisted after being squeezed when the cutting knife 49 cuts the cable, resulting in an uneven cutting surface caused by the cutting knife 49 on the cable. A fixed rotating shaft 44 is arranged on one side of the support plate 42;

[0038] A matching clamping knife 45 is arranged on the fixed rotating shaft 44. Two matching clamping knives 45 are arranged. The blades of the two clamping knives face the same direction, and the two clamping knives are fixedly connected to the fixed rotating shaft 44 through a circular fixed ring. When the cutting knife 49 is worn and needs to be replaced, the matching clamping knife 45 will be replaced through the arranged transmission assembly 6, thereby changing the blade direction of the matching clamping knife 45, so that the matching clamping knife 45 can cooperate with the new cutting knife 49 to cut the cable. A hydraulic rod 46 is arranged on the swing arm 41. A cavity is opened on the swing arm 41 for accommodating the hydraulic rod 46. At the same time, a part of the hydraulic rod 46 is placed in the cavity of the swing arm 41. A circular clamping ring is arranged at one end of the hydraulic rod 46 away from the swing arm 41. A clamping rotation relationship is formed between the circular clamping ring and the clamping column 47, so that when the clamping column 47 rotates, the hydraulic rod 46 will not rotate accordingly.

[0039] A clamping column 47 is movably arranged at one end of the hydraulic rod 46 away from the swing arm 41, and a placement seat 48 is arranged on the clamping column 47. The placement seat 48 is fixedly connected to the clamping column 47. The placement seat 48 is symmetrical as a whole. At the same time, two placement grooves are arranged inside the placement seat 48 for placing a new cutting knife 49 and a used cutting knife 49. When the clamping column 47 rotates, the placement seat 48 is driven to rotate synchronously. At this time, the cutting knife 49 placed inside the placement seat 48 will be swapped due to the rotation of the placement seat 48. In the process of swapping the position of the cutting knife 49, the direction of the blade of the cutting knife 49 will change, thereby changing the cutting direction of the cable being cut, so as to prevent the new cutting knife 49 from scratching the cutting surface of the broken cable when cutting along the previous cutting path;

[0040] The cutting knife 49 is symmetrically and movably arranged on the placement seat 48. The cutting knife 49 is arc-shaped and is movably placed in the internal placement groove of the placement seat 48. When cutting, the entire placement seat 48 is driven to move by the hydraulic rod 46, so that the cutting knife 49 and the matching clamping knife 45 form a shearing effect on the cable, thereby cutting the cable.

[0041] A driving assembly 5 is provided on the side of the placement seat 48 away from the engaging column 47. The driving assembly 5 is used to start after receiving the starting signal of the control console 1 to replace the cutting knife 49. A transmission assembly 6 is provided on the swing arm 41. The transmission assembly 6 is used to transmit power. The placement seat 48 is symmetrically provided with arc-shaped clamping plates 481 inside. The arc-shaped clamping plates 481 are used to clamp the cutting knife 49 stably. During the whole clamping process, the arc-shaped clamping plates 481 provide pulling force to the arc-shaped clamping plates 481 through the sliding plate 482 and the first spring 483 provided inside the placement seat 48, so that the arc surface of the arc-shaped clamping plates 481 is attached to the surface of the cutting knife 49 to prevent the cutting knife 49 from falling off during the working process.

[0042] A sliding plate 482 is provided on one side of the arc-shaped clamping plate 481, and the sliding plate 482 is fixedly connected to the arc-shaped clamping plate 481. A pulling force is generated on the arc-shaped clamping plate by a first spring 483 provided inside the placement seat 48, so that the sliding plate 482 can generate a certain clamping force on the cutting knife 49. A first spring 483 is provided on the side of the sliding plate 482 close to the arc-shaped clamping plate 481, and the first spring 483 is fixedly connected to the sliding plate 482. When the cutting knife 49 is installed inside the placement seat 48, the arc-shaped clamping plate 481 will be squeezed to displace, and the first spring 483 will simultaneously provide pulling force to the displaced arc-shaped clamping plate 481, so that the arc-shaped clamping plate 481 has a tendency to reset, so that the arc-shaped clamping plate 481 can provide a certain squeezing force on the cutting knife 49, thereby clamping the cutting knife 49.

[0043] A laser sensor 411 is arranged on the side of the swing arm 41 away from the semi-ring matching plate 43. The laser sensor 411 is used to monitor the time taken by the cutting knife 49 to cut the cable. When the placement seat 48 on which the cutting knife 49 is placed pauses and does not move in place, the laser sensor 411 transmits a signal to the control system inside the console 1, and the control system controls the drive assembly 5 to start, so that the current cutting knife 49 is replaced in time to avoid the situation where the cable cannot be cut;

[0044] A baffle plate 412 is provided on the side of the swing arm 41 close to the laser sensor 411. The baffle plate 412 has an arc-shaped opening at the end away from the hydraulic rod 46, and an elastic retractable plate is placed in the opening. The arc-shaped opening is consistent with the cutting opening formed after the cutting knife 49 is replaced, so that the staff can take out the severely worn cutting knife 49 from the inside of the placement seat 48 in time after observing that the cutting knife 49 is replaced, and replace the new cutting knife 49. At the same time, after the replacement is completed, the entire placement seat 48 is reset so that the cutting opening of the cutting knife 49 placed inside is facing the direction of the hydraulic rod 46 again;

[0045] A moving groove 413 is formed through the swing arm 41, and the moving groove 413 is used to facilitate the movement of the placement seat 48 to avoid the placement seat 48 being limited in movement during the movement process, resulting in the cutting knife 49 being unable to move to the specified position to shear the cable.

[0046] A movable guide rail 414 is provided on the side of the swing arm 41 away from the baffle 412. The movable guide rail 414 is used for the second clamping ring 416 to move synchronously through the L-shaped connecting rod 417. The movable guide rail 414 can limit the movement of the second clamping ring 416 to a certain extent to prevent it from moving excessively. A first clamping ring 415 is provided at one end of the movable guide rail 414. The first clamping ring 415 is semi-annular and is used to cooperate with the second clamping ring 416. When the engaging column 47 drives the second clamping ring 416 to move through the L-shaped connecting rod 417, the first clamping ring 415 and the second clamping ring 416 will gradually form a ring shape to limit the cable inside it to prevent the cable from moving randomly during the entire cutting operation. At the same time, during the cutting process, when the tool is replaced, the first clamping ring 415 and the second clamping ring 416 can prevent the cable from moving away from the current position, resulting in the cutting tool 49 being unable to completely cut the cable.

[0047] A second clamping ring 416 is movably provided on the movable guide rail 414, and balls are provided on the first clamping ring 415 and the second clamping ring 416. These balls reduce friction and avoid scratches and wear on the surface of the cable during clamping. At the same time, the balls can also prevent the cable from being unable to smoothly detach from the clamping ring after clamping. An L-shaped connecting rod 417 is provided on the second clamping ring 416, and the other end of the L-shaped connecting rod 417 is fixedly connected to the locking column 47. When the locking column 47 is moved by the hydraulic rod 46, the second clamping ring 416 can be moved synchronously by the L-shaped connecting rod 417 to clamp the cable.

[0048] A rotating disk 21 is symmetrically arranged on the rotating disk 2, and the rotating disk 21 is fixedly connected to the polymorphic rotating shaft 3. An elastic clamp block 22 is symmetrically arranged on the rotating disk 21. The elastic clamp block 22 is used to clamp the broken end of the cable through the elastic clamp block 22 when the cable is wound on the new winding drum 31, so that the cable can be rewound on the new winding drum 31.

[0049] During use, when it is necessary to replace a new take-up drum 31 for cable take-up operation, the entire rotating disk 2 will rotate to exchange the positions of the old and new take-up drums 31, and then the swing arm 41 will be lifted, and then the swing arm 41 set will fall under the control of the console 1 to intercept the connected cable, and then the hydraulic rod 46 drives the clamping column 47 to move, and under the movement of the clamping column 47, the placement seat 48 with the cutting knife 49 placed is driven to move synchronously, and at the same time, the second clamping ring 416 is driven by the action of the L-shaped connecting rod 417, so that the cable is pushed under the action of the second clamping ring 416, and then the cable is restricted under the action of the second clamping ring 416 and the first clamping ring 415, when the placement seat 48 drives the cutting knife 49 and the matching clamping knife 45 to cut the cable, during the entire cutting process, when the placement seat 48 enters the detection area of ​​the laser sensor 411 When the placement seat 48 is within the range, the laser sensor 411 will always detect the current position of the placement seat 48. When the placement seat 48 stops and does not move, the laser sensor 411 will transmit a signal to the inside of the console 1, so that the console 1 starts the driving component 5 to work, so that the set placement seat 48 and the matching clamping knife 45 are replaced. During the entire replacement process, the transmission component 6 will transmit power to the fixed rotating shaft 44 with the matching clamping knife 45, so that the matching clamping knife 45 is replaced slightly faster than the cutting knife 49. After the entire cutting knife 49 is replaced, the hydraulic rod 46 will drive the replaced cutting knife 49 to move in the opposite direction along the previous moving direction, and cut from the other side of the cable. This not only avoids the surface wear of the previous cutting surface of the cable on the new cutting knife 49, but also when cutting the cable from the other side of the cable, it can also cut the cable faster and complete the entire cutting operation. Example 2

[0050] See also Figures 1 to 8 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0051] The driving assembly 5 includes a square extension rod 51 arranged on the side of the placement seat 48 away from the engaging column 47. The square extension rod 51 and the placement seat 48 are in an engaging relationship. Through the square notch on the placement seat 48 and the square shape of the square extension rod 51, one end of the square extension rod 51 is embedded in the placement seat 48, so that when the square extension rod 51 rotates, the placement seat 48 can rotate synchronously. A moving cylinder 52 is arranged on the side of the square extension rod 51 away from the placement seat 48. The moving cylinder 52 is a T-shape, and a unidirectional spiral groove is provided on the surface of the moving cylinder 52. The rotation direction of the spiral groove is opposite to the rotation direction of the matching cylinder 53. Through the groove and the push rod 531 provided inside the matching cylinder 53, when the matching cylinder 53 rotates, the moving cylinder 52 will move first. When one side of the moving cylinder 52 contacts the external cylinder 57 so that it cannot continue to move, the moving cylinder 52 will rotate, thereby driving the placement seat 48 to rotate synchronously through the square extension rod 51;

[0052] A matching cylinder 53 is movably arranged outside the moving cylinder 52, and a push rod 531 is arranged inside the matching cylinder 53, and the push rod 531 contacts the spiral groove on the moving cylinder 52. A square shaft 54 ​​is arranged on the side of the matching cylinder 53 away from the square extension rod 51, and the square shaft 54 ​​is retractable, so that the matching cylinder 53 can have enough space to move. A starting motor 55 is arranged on the side of the square shaft 54 ​​away from the matching cylinder 53, and the starting motor 55 is used to start after receiving a signal from the control console 1, and drive the square shaft 54 ​​to rotate. Under the rotation of the square shaft 54, the matching cylinder 53 is driven to rotate synchronously, so that the movably arranged moving cylinder 52 moves first, and then rotates to drive the placement seat 48 to rotate synchronously;

[0053] A rotating collar 56 is provided on the square shaft 54, and is used for synchronously rotating with the square shaft 54. During the rotation, power is transmitted to the transmission shaft 62 through a conveyor belt 61 provided on the rotating collar 56. An external cylinder 57 is movably provided on the rotating collar 56 away from the starter motor 55. The external cylinder 57 and the rotating collar 56 are engaged and rotated, so that when the rotating collar 56 rotates, the external cylinder 57 does not synchronously rotate with it. The external cylinder 57 wraps the moving cylinder 52 therein, and an I-shaped groove is provided inside the external cylinder 57, so that when the moving cylinder 52 contacts the groove, it will no longer continue to move, so that the moving cylinder 52 can change from moving to rotating.

[0054] A supporting plate 571 is arranged on the outside of the external cylinder 57, and the other end of the supporting plate 571 is rotatably connected to the transmission shaft 62, so that when the transmission shaft 62 rotates, the supporting plate 571 will not affect it. A push rod 531 is arranged on the side of the matching cylinder 53 close to the moving cylinder 52, and a snap-fitting relationship is formed between the push rod 531 and the spiral groove on the moving cylinder 52. When the push rod 531 squeezes the moving cylinder 52 to move, when the moving cylinder 52 and the external cylinder 57 come into contact, the continued movement of the push rod 531 will prompt the moving cylinder 52 to rotate, thereby completing the transmission of power.

[0055] The rotation of the rotating sleeve 56 transmits the power to the transmission shaft 62 through the conveying belt 61. At the same time, the rotation of the matching cylinder 53 directly engages and slides with the spiral groove on the moving cylinder 52 which is opposite to the rotation of the matching cylinder 53 through the push rod 531, and first drives the moving cylinder 52 to move. When the side surface of the moving cylinder 52 contacts the inner wall of the external cylinder 57, the moving cylinder 52 is rotated by the rotation of the push rod 531. At this time, the rotation of the moving cylinder 52 will drive the entire placement seat 48 to rotate, and the position of the new and old cutting knives 49 is replaced. When the cutting knife 49 is severely worn and cannot smoothly cut the cable during the cutting process, the cutting knife 49 is replaced to continue the subsequent cutting operation, and the entire cable winding work is completed without stopping the machine during this process.

[0056] The remaining structures are the same as those of Example 1. Example 3

[0057] See also Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0058] The transmission assembly 6 includes a conveying belt 61 arranged on the rotating ring 56, a transmission shaft 62 arranged on the side of the conveying belt 61 away from the rotating ring 56, the transmission shaft 62 is rotatably engaged with the supporting fixed plate 571, and is used to support the transmission shaft 62 without affecting the rotation of the transmission shaft 62 itself, a one-way ratchet 63 arranged on the transmission shaft 62, and the one-way ratchet 63 is used for unidirectional power transmission, and a support extension plate 64 is arranged on the end of the transmission shaft 62 away from the conveying belt 61, and the support extension plate 64 is fixedly connected to the swing arm 41, and the support extension plate 64 is retractable. The transmission shaft 62 is supported and positioned by the action of the support extension plate 64 and the supporting fixed plate 571, so that the transmission shaft 62 can move synchronously with the rotating ring 56.

[0059] The transmission assembly 6 also includes a multi-stage extension rod 65 arranged on the side of the swing arm 41 close to the support extension plate 64, the multi-stage extension rod 65 is used to support the mobile toothed plate 66, and the multi-stage extension rod 65 can provide the mobile toothed plate 66 with a certain moving distance, the mobile toothed plate 66 arranged on the side of the multi-stage extension rod 65 away from the swing arm 41, the mobile toothed plate 66 has a certain cavity inside, and a plurality of second springs 661 are arrayed inside the cavity, and the second springs 661 provide elastic force to the one-way rack 662, when the one-way ratchet 63 rotates in the opposite direction of the one-way rack 662, the one-way rack 662 is pushed to drive the mobile toothed plate 66 to move;

[0060] A rotating gear 67 is arranged on the side of the support plate 42 close to the fixed shaft 44, and the rotating gear 67 is connected to the support plate 42 through a rotating rod, and the rotating gear 67 is meshed with the teeth arranged on the moving toothed plate 66. A transmission gear 68 is arranged on the end of the fixed shaft 44 close to the rotating gear 67, and the transmission gear 68 is meshed with the rotating gear 67, and there is a certain space distance between the position of the transmission gear 68 and the moving toothed plate 66, so that the moving toothed plate 66 will not contact with the transmission gear 68 when moving. A second spring 661 is arranged in an array inside the moving toothed plate 66;

[0061] The one-way rack 662 is movably arranged on the movable tooth plate 66, and a plug-in relationship is formed between the one-way rack 662 and the movable tooth plate 66, so that the one-way rack 662 can be reciprocated and lifted. At the same time, the groove arranged on the movable tooth plate 66 will limit the movement of the one-way rack 662 to prevent the one-way rack 662 from detaching from the movable tooth plate 66 when moving.

[0062] A fixed U-plate 663 is provided on the side of the movable tooth plate 66 away from the multi-stage extension rod 65. A certain space is provided in the middle of the fixed U-plate 663, so that when the transmission shaft 62 is separated from the one-way rack 662, the fixed U-plate 663 will not contact with the transmission shaft 62, thereby preventing the transmission shaft 62 from being unable to move out normally. A fixed rod 664 is provided on the side of the fixed U-plate 663 close to the one-way rack 662, and the fixed rod 664 passes through the swing arm 41. A third spring 665 is provided on the outside of the fixed rod 664. The third spring 665 is located between the end of the fixed rod 664 away from the fixed U-plate 663 and the swing arm 41, and is used to provide a certain elastic force so that the movable tooth plate 66 can be automatically reset in the absence of external force.

[0063] When the conveyor belt 61 transmits power to the transmission shaft 62, the transmission shaft 62 drives the one-way ratchet 63 to rotate, and at the same time cooperates with the one-way rack 662 set on the moving tooth plate 66 to drive the entire moving tooth plate 66 to move. Under the movement of the moving tooth plate 66, the power is transmitted to the fixed shaft 44 through the rotating gear 67, and then the two matching clamping knives 45 are swapped under the rotation of the fixed shaft 44 to change the current blade direction of the matching clamping knife 45. Then, the entire placement seat 48 is pushed by the hydraulic rod 46 to move in the opposite direction to cut the cable, completing the entire cutting process. After the entire placement seat 48 is pushed to the initial position by the hydraulic rod 46, the staff can remove the severely worn cutting knife 49 by pressing the elastic telescopic plate on the baffle 412, replace it with a new cutting knife 49, and then reset the opening direction of the entire placement seat 48 by starting the motor 55 to facilitate the next cutting operation. The resetting of the matching clamping knife 45 is provided by the elastic force provided by the third spring 665, so that the movable tooth plate 66 can be automatically reset in the absence of external force, and the opening direction of the matching clamping knife 45 is reset under the resetting of the movable tooth plate 66.
