Description

Technical Field

[0001] The present application relates to the technical field of winding amorphous three-dimensional coiled iron cores, and in particular to an automatic unwinding double-station winding machine for amorphous three-dimensional coiled iron cores. Background Art

[0002] At present, amorphous three-dimensional winding transformers have been gradually accepted by the majority of users due to their advantages such as low loss, low noise, strong overload capacity, low no-load current, compact structure, and low power transformation cost. The amorphous three-dimensional winding core in the amorphous three-dimensional winding transformer is the most commonly used core in the existing distribution transformer. The amorphous three-dimensional winding core is composed of three identical single frames, and the three core columns of the assembled core are arranged in an equilateral triangle. Each single frame is continuously wound by a trapezoidal strip.

[0003] In the prior art, it is necessary to manually pull the uncut amorphous three-dimensional rolled iron core to the oblique cutting machine, and then use the special oblique cutting machine to cut the material obliquely to obtain a trapezoidal material strip. After this oblique cutting process, there will be positive and negative directions, so it is necessary to manually pull the positive amorphous three-dimensional rolled iron core to the winding device for winding. After winding the positive amorphous three-dimensional rolled iron core, it is also necessary to manually unwind the other reverse amorphous three-dimensional rolled iron core that has been cut, and then pull the positive amorphous three-dimensional rolled iron core to the winding device for winding.

[0004] Regarding the above-mentioned related technologies, it is troublesome and inefficient to manually pull the rolled uncut amorphous three-dimensional coiled iron core to the diagonal cutting machine. Manual pulling may also result in inaccurate operation, resulting in large deviations in the cutting or winding effects, and the risk of injury due to operational errors, so improvements are made.

[0008] The automatic feeding device is arranged between the mounting plate and the material cutting machine, and comprises a first end transfer roller, a second end transfer roller, a transmission assembly and a driving assembly. The unloading motor drives the core roll on the unloading roller to rotate, and the end of the core roll enters between the first end transfer roller and the second end transfer roller. The driving assembly is used to drive the first end transfer roller to approach the second end transfer roller to clamp the end of the core roll.

[0009] The transmission component includes an upper transmission roller group, a lower transmission roller group, a transmission belt and a transmission motor, the upper transmission roller group and the lower transmission roller group are both provided with transmission gears, the transmission gears are connected by the transmission belt, the transmission motor is arranged at the end of one of the upper transmission roller groups, and is used to drive the upper transmission roller group and the lower transmission roller group to transmit the unfolded iron core roll to the cutting machine, and the driving component is also used to move the unfolded end of the iron core roll to the transmission component through the first end transfer roller and the second end transfer roller;

[0010] A first material dividing transmission roller group and a second material dividing transmission roller group are arranged on one side of the material dividing machine away from the mounting plate, one end of the first material dividing transmission roller group is close to the material dividing machine, and the other end is close to the first winding device, and is used for transmitting and winding one of the two core rolls after dividing;

[0011] The second material distribution transmission roller group includes a first material discharge roller group and a second material discharge roller group, the second material discharge roller group is arranged on a side of the first material discharge roller group away from the material opening machine, the material discharge device is arranged between the first material discharge roller group and the second material discharge roller group, one end of the second material discharge roller group is arranged close to the material discharge device, and the other end is arranged close to the second winding device, which is used to transport and wind up the other of the two core rolls after distribution, and the material discharge device is used to discharge one of the two core rolls after distribution, so as to facilitate winding;

[0012] A first detection component is arranged above the second material unloading roller group for detecting whether there is a curling edge on the core roll after material separation before the core roll is transmitted and rolled into shape, and a second detection component is arranged above the first material separation transmission roller group for detecting whether there is a curling edge on the core roll after material separation before the core roll is transmitted and rolled into shape.

[0013] By adopting the above technical solution, the unloading motor is started, and the unloading motor drives the core roll on the unloading roller to rotate. During the rotation of the core roll, the end of the core roll will naturally droop and enter between the first end transfer roller and the second end transfer roller. The driving component in the present application can drive the first end transfer roller to move toward the second end transfer roller, so as to clamp the end of the core roll, and the driving component can also move the end of the core roll to the transmission component through the first end transfer roller and the second end transfer roller, start the transmission motor, and the transmission motor The upper transmission roller group and the lower transmission roller group are driven to rotate by the transmission gear and the transmission belt, so that the end of the iron core roll is transmitted to the cutting machine.

In the conventional technology, since the core roll needs to be divided into two trapezoids, when the divided core rolls are finally wound up, the two divided core rolls need to be wound up from the narrow head or the wide head. Therefore, when one of the divided core rolls is directly wound up, the other needs to be unwound first. The unwound device in the present application can be used for winding up the core rolls. When one core roll is being wound up, the other core roll is being unwound at the same time, thereby improving the efficiency of processing, winding and forming the core roll; when the cutting machine cuts the core roll, since the two core rolls after the cutting need to be transmitted separately, a large angle will appear between the two core rolls, which may cause curling of the core rolls after the cutting, thereby affecting the final forming quality.

Two groups of driven gears are arranged, and the two groups of driven gears are respectively arranged at the ends of the first end transfer roller and the second end transfer roller and mesh with each other. The driving gear is arranged on the upper transmission roller group and meshes with the transmission gear closest to the discharge roller. The swing structure is used to swing the first end transfer roller and the second end transfer roller through the swing block so that the driving gear and the driven gear mesh with each other. The limit member is used to fix the second mounting block on the mounting plate when the first mounting block and the second mounting block are separated.

The present application can perform preliminary flattening on the unfolded core roll and keep the opened core roll at a certain degree of tightness during traction, thereby improving the cutting effect of the cutting machine, and at the same time avoiding direct contact between the staff and the cutting machine, thereby reducing the possibility of staff being injured due to improper operation.

At this time, the first end transfer roller and the second end transfer roller are on the same vertical line, thereby realizing the swinging of the first end transfer roller and the second end transfer roller, and realizing the mutual meshing of the driving gear and the driven gear.

[0019] By adopting the above technical solution, when the first mounting block drives the second mounting block to move in the direction of the discharge roller, it is necessary to achieve separation between the first mounting block and the second mounting block. Therefore, when the first moving block is moving, the wedge block extends from the mounting groove under the action of the reset member and enters the clamping groove on the mounting plate, thereby achieving separation between the first mounting plate and the second mounting plate.

[0022] Optionally, the unloading assembly includes a winding and unwinding motor and an air pump, the winding and unwinding motor is arranged on a side of the mounting disk away from the winding roller, and the output shaft is connected to the winding roller, the air pump is arranged at the end of the winding roller away from the mounting disk, the winding roller is provided with a central hole inside, and a negative pressure hole is opened on the side wall, the air pump exhausts air from the inside of the winding roller to create negative pressure at the negative pressure hole to adsorb the end of the core roll behind the powder material.

[0023] By adopting the above technical solution, the reeling and unreeling motor is used to rotate the reeling roller forward and reverse, so as to realize the reeling and unreeling of the cut iron core roll through the reeling roller, and the vacuum pump can evacuate the inside of the reeling roller, so as to form a negative pressure at the negative pressure hole, so as to facilitate the adsorption and grasping of the end of the cut iron core roll.

[0025] By adopting the above technical scheme, the end of the core roll after dividing is passed through between the moving roller and the fixed roller and bent downward to be sucked and grabbed by the negative pressure hole. When the core roll wrapped on the winding roller becomes thicker and thicker, the moving roller will be pushed to move toward the fixed roller. When the other end of the core roll after dividing is located between the moving roller and the fixed roller, the moving roller and the fixed roller are just in a position to limit and clamp the other end of the core roll after dividing. When winding the core roll onto the winding roller, the moving roller can also squeeze the core roll that has been wound up, so that the winding is more fitted, avoiding stress inside the core roll that has been wound up, resulting in poor winding quality.

The drive is arranged on the baffle to move the baffle according to the change of the width of the core roll. The second detection component is arranged the same as the first detection component.

[0029] By adopting the above technical solution, a part of the linear laser emitted by the laser transmitter will be intercepted by the shielding plate, and the linear laser that is not blocked will irradiate the core coil under the laser transmitter. The driving part adjusts the position of the shielding plate according to the winding speed of the strip to ensure that the linear laser that is not blocked is completely irradiated on the core coil. When the core coil under the laser transmitter has curling, the width of the strip will be reduced, so a part of the linear laser will be irradiated on the laser detector. According to whether there is feedback from the laser detector, it is detected whether there is curling before the core coil is finally wound, so as to improve the quality of the final winding of the core coil.

[0030] Optionally, the first material distribution transmission roller group, the first material discharge roller group and the second material discharge roller group are all provided with a fixed plate at the end away from the cutting machine, the fixed plate is provided with a telescopic groove, a telescopic plate is provided in the telescopic groove, and an elastic member is provided between the bottom wall of the telescopic groove and the telescopic plate.

[0031] By adopting the above technical solution, the fixed plate and the telescopic plate can reduce the hanging length of the end of the core coil, thereby further facilitating the winding of the core coil and improving the winding quality.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. In conventional technology, since the core roll needs to be divided into two trapezoids, when the divided core roll is finally rolled up, the two divided core rolls need to be rolled up from the narrow end or the wide end. Therefore, when one of the divided core rolls is directly rolled up, the other needs to be unwound first. The unwound device in the present application can unwound the other core roll at the same time as one of the core rolls is rolled up, thereby improving the efficiency of processing, rolling and forming the core roll; when the opening machine opens the core roll, since the two divided core rolls need to be transmitted separately, a large angle will appear between the two core rolls, which may cause curling of the divided core rolls, thereby affecting the final forming quality. The first detection component and the second detection component in the present application can perform width detection on the two divided core rolls to avoid the final rolling of the core rolls with curling, thereby improving the processing and rolling quality of the core rolls;

[0034] 2. The fully automatic unloading of the material opening machine is realized, which saves the time of unloading the material opening machine. Manual traction may cause wrinkles and curling of the core roll. The present application can initially flatten the unfolded core roll and keep the opened core roll at a certain degree of tightness during traction, thereby improving the opening effect of the material opening machine. At the same time, it also avoids direct contact between the staff and the material opening machine, thereby reducing the possibility of staff being injured due to improper operation.

[0035] 3. The end of the core roll after the material separation passes through between the moving roller and the fixed roller, bends downward, and is sucked and grabbed by the negative pressure hole. When the core roll wound on the winding roller becomes thicker and thicker, it will push the moving roller to move toward the fixed roller. When the other end of the core roll after the material separation is located between the moving roller and the fixed roller, the moving roller and the fixed roller are just in a position to limit and clamp the other end of the core roll after the material separation. When the core roll is wound onto the winding roller, the moving roller can also squeeze the wound core roll, so that the wound core roll is more closely fitted, avoiding stress inside the wound core roll, which leads to poor winding quality.

[0036] 4. Multiple winding rollers, unwinding components and tail fixings can realize unwinding and winding the core roll after unwinding, and unwinding another core roll that has been unwound and wound, thereby further improving the final winding efficiency of the core roll;

[0037] 5. A portion of the linear laser emitted by the laser transmitter will be intercepted by the shielding plate, while the unshielded linear laser will irradiate the core coil under the laser transmitter. The driver adjusts the position of the shielding plate according to the winding speed of the strip to ensure that all the unshielded linear lasers are irradiated on the core coil. When the core coil under the laser transmitter has curling, the width of the strip will be reduced, so a portion of the linear laser will irradiate the laser detector. Depending on whether there is feedback from the laser detector, it is possible to detect whether the core coil has curling before the final winding of the core coil, so as to improve the quality of the final winding of the core coil.

The first mounting block 34 When the second mounting block 347 abuts against the first mounting block 346, the second mounting block 347 is overlapped and mounted on the first mounting block 346, the side of the swing block 345 away from the connecting rod 344 is welded to the first mounting block 346, the first end transfer roller 31 is mounted on the side of the first mounting block 346 away from the swing block 345, the second end transfer roller 32 is mounted on the side of the second mounting block 347 away from the swing block 345, two groups of driven gears 349 are installed, the two groups of driven gears 349 are respectively installed on the ends of the first end transfer roller 31 and the second end transfer roller 32 and mesh with each other, the driving gear 348 is installed on the upper transmission roller group 331, and meshes with the transmission gear 335 closest to the discharge roller.

[0053] The driving motor 341 drives the screw rod 342 to rotate. Since the screw rod 342 is threadedly connected to the moving block 343, the moving block 343 can be driven to move. During the movement of the moving block 343, the connecting rod 344 drives the swing block 345 to move synchronously. During the movement of the swing block 345, the swing block 345 will swing ninety degrees to the left and right of the swing structure 35, thereby driving the first mounting block 346 connected to the swing block 345 to swing ninety degrees synchronously. In this embodiment, the first mounting block 346 is installed in a rectangular shape, and the second mounting block 347 is installed in an "L" shape. When the first mounting block 346 and the second mounting block 347 are abutted, the second mounting block 347 will overlap the first mounting block 346. Therefore, when the first mounting block 346 rotates ninety degrees, it can drive the second mounting block 347 to swing ninety degrees synchronously. The first end transfer roller 31 and the second end transfer roller 32 rotate in a same vertical line, and the driving gear 348 and the driven gear 349 are meshed with each other, and the driven gear 349 is driven to rotate by the transmission gear 335, so that the first end transfer roller 31 and the second end transfer roller 32 automatically convey the end of the core roll to between the upper transmission roller group 331 and the lower transmission roller group 332, thereby realizing the fully automatic unloading of the cutting machine 4 and saving the time for unloading the cutting machine 4. Manual traction may cause wrinkles and curling of the core roll. The present application can perform preliminary flattening on the unfolded core roll and keep the opened core roll at a certain degree of tightness during traction, thereby improving the cutting effect of the cutting machine 4 and avoiding direct contact between the staff and the cutting machine 4, thereby reducing the possibility of staff being injured due to improper operation.

[0054] Reference Figure 5 The swing structure 35 in this embodiment is used to swing the first end transfer roller 31 and the second end transfer roller 32 through the swing block 345, so that the driving gear 348 and the driven gear 349 are meshed with each other. Therefore, the swing structure 35 in this embodiment includes a wide section groove 351 and a narrow section groove 352. The wide section groove 351 and the narrow section groove 352 are both opened on the mounting plate 1. The swing block 345 includes a semi-elliptical end and a semicircular end. The height of the semi-elliptical end is greater than the diameter of the semicircular end. The width of the narrow section groove 352 is set with the diameter of the semicircular end. The connection between the connecting rod 344 and the swing block 345 is located at the center of the semicircular end. When the swing block 345 is located in the wide section groove 351, the semi-elliptical end is located above the semicircular end. When the swing block 345 is located in the narrow section groove 352, the semi-elliptical end and the semicircular end are located on the same horizontal line.

[0055] When the swing block 345 is located in the wide groove 351, the semi-elliptical end and the semicircular end are on the same vertical line. At this time, the first end transfer roller 31 and the second end transfer roller 32 are on the same horizontal line. When the swing block 345 is about to enter the narrow groove 352, since the width of the narrow groove 352 is set to the same diameter as the semicircular end, and the moving block 343 continues to move the swing block 345 through the connecting rod 344, the swing block 345 will rotate ninety degrees, and at the same time drive the first end transfer roller 31 and the second end transfer roller 32 to swing ninety degrees toward the transmission component 33. At this time, the first end transfer roller 31 and the second end transfer roller 32 are on the same vertical line, so as to realize the swinging of the first end transfer roller 31 and the second end transfer roller 32, and realize the mutual meshing of the driving gear 348 and the driven gear 349.

[0056] Reference Figure 4 and Figure 5 The limiting member 36 in this embodiment is used to fix the second mounting block 347 on the mounting plate 1 when the first mounting block 346 and the second mounting block 347 are separated. Therefore, the limiting member 36 in this embodiment includes a wedge block 361 and a reset member. A mounting groove is provided on the second mounting block 347, and the wedge block 361 is installed in the mounting groove. A clamping groove is provided on the mounting plate 1 corresponding to the wedge block 361. The reset member is installed between the bottom of the mounting groove and the wedge block 361. When the first mounting block 346 and the second mounting block 347 are separated, the reset member drives the wedge block 361 to extend into the clamping groove. When the first mounting block 346 drives the second mounting block 347 to move in the direction of the discharge roller, it is necessary to achieve separation between the first mounting block 346 and the second mounting block 347. Therefore, when the first moving block 343 is moving, the wedge block 361 extends from the mounting groove under the action of the reset member and enters the clamping groove on the mounting plate 1, thereby achieving separation between the first mounting plate 1 and the second mounting plate 1. In this embodiment, the reset member is a spring, which is a preferred method of this embodiment. In other embodiments, the reset member may be an elastic rubber pad.

[0057] Reference Figure 1 , Figure 2 and Figure 6The material unloading device 5 includes a mounting plate 51, a material unloading motor 52, a winding roller 53, a material unloading assembly 54 and a tail fixing piece 55. The mounting plate 51 is rotatably mounted on the mounting frame 2, the material unloading motor 52 is fixedly mounted on the mounting frame 2 and the output shaft is connected to the mounting plate 51, the winding roller 53 is rotatably mounted on the side of the mounting plate 51 away from the material unloading motor 52, the material unloading assembly 54 is mounted on the mounting plate 51 and the winding roller 53, and is used to wind the core roll after material separation onto the winding roller 53 when the winding roller 53 is close to the first material unloading roller group 91, and unwind the core roll wound on the winding roller 53 when the winding roller 53 is close to the second material unloading roller group 92, and the tail fixing piece 55 is used to fix the outer end of the core roll wound on the winding roller 53, and realize automatic unwinding when the core roll is unwound.

[0058] Start the unloading motor 52 to drive the mounting plate 51 to rotate, thereby moving the winding roller 53 to a position close to the first unloading roller group 91, and then unloading and winding the cut core roll under the action of the unloading assembly 54, and the tail fixing part 55 can limit the outer end of the cut core roll when the winding of the cut core roll is completed, so as to facilitate the subsequent automatic unwinding; after the winding is completed, the unloading motor 52 is used to move the wound winding roller 53 to a position close to the second unloading roller group 92, and at this time, the unloading assembly 54 is used to automatically unwind the cut core roll, so that the unloaded core roll is transported to the second unloading roller group 92, and finally transported to the second winding device 7 through the second unloading roller group 92 for final winding.

[0059] Reference Figure 6 The material unloading assembly 54 includes a reeling and winding motor 541 and an air pump 542. The reeling and winding motor 541 is installed on the side of the mounting plate 51 away from the reeling roller 53, and the output shaft is connected to the reeling roller 53. The air pump 542 is installed at the end of the reeling roller 53 away from the mounting plate 51. The reeling roller 53 is installed in the middle hole inside, and a negative pressure hole 543 is opened on the side wall. The air pump 542 evacuates the inside of the reeling roller 53 to create negative pressure at the negative pressure hole 543 to adsorb the end of the core roll behind the powder.

[0060] The reeling and unreeling motor 541 is used to rotate the reeling roller 53 forward and reverse, so that the reeling roller 53 can reel in and unreel the cut core roll, and the vacuum pump 542 can evacuate the inside of the reeling roller 53, so as to form a negative pressure at the negative pressure hole 543, so as to facilitate the adsorption and grasping of the end of the cut core roll. Compared with manually winding the end of the cut core roll on the reeling roller 53, the use of negative pressure can save time, realize full automation, and avoid the situation of winding misalignment caused by manual operation.

[0061] Reference Figure 6The tail fixing part 55 includes a moving roller 551 and a fixed roller 552. The moving roller 551 is slidably installed on the side of the mounting plate 51 away from the material unloading motor 52, and the fixed roller 552 is fixedly installed on the side of the mounting plate 51 away from the material unloading motor 52. The end of the core roll after the material is divided passes through the moving roller 551 and the fixed roller 552 and is bent downward and adsorbed by the negative pressure hole 543. When the winding roller 53 winds up the core roll after the material is divided, it pushes the moving roller 551 to move toward the fixed roller 552 until the moving roller 551 and the fixed roller 552 clamp and fix the outer end of the wound core roll.

[0062] The end of the core roll after the separation passes through the downward bend between the moving roller 551 and the fixed roller 552 and is sucked and grabbed by the negative pressure hole 543. When the core roll wrapped on the winding roller 53 becomes thicker and thicker, the moving roller 551 will be pushed to move toward the fixed roller 552. When the other end of the core roll after the separation is located between the moving roller 551 and the fixed roller 552, the moving roller 551 and the fixed roller 552 are just in a position to limit and clamp the other end of the core roll after the separation. When the core roll is wound onto the winding roller 53, the moving roller 551 can also squeeze the already wound core roll, so that the winding is more fitted, avoiding stress inside the already wound core roll and causing poor winding quality.

[0063] Reference Figure 1 and Figure 2 , multiple groups of winding rollers 53 are installed, and the multiple groups of winding rollers 53 are installed at intervals and around the center of the mounting plate 51. Multiple groups of unwinding components 54 and tail fixings 55 are installed corresponding to the number of groups of winding rollers 53. Multiple winding rollers 53, unwinding components 54 and tail fixings 55 can realize unwinding of another core roll that has been unwound and wound while unwinding the core roll after unwinding, thereby further improving the final winding efficiency of the core roll. In this embodiment, four groups of winding rollers 53, unwinding components 54 and tail fixings 55 are provided. Four groups are a preferred mode of this embodiment, and can be adjusted according to actual needs in other embodiments.

[0064] After the core roll is cut by the cutter 4, since the two core rolls are to be transported separately, a large angle will appear between the two core rolls, which may cause curling of the core roll after the cut, thus affecting the final molding quality. Figure 7Therefore, the first detection component 10 in this embodiment includes a laser emitter 101, a laser detector 102, a baffle 103 and a driving member 104. The laser emitter 101 is installed above the second feed roller group 92 for emitting linear laser. The laser detector 102 is installed on the second feed roller group 92 for receiving the laser emitted by the laser emitter 101. The baffle 103 is installed between the laser emitter 101 and the laser detector 102 for shielding the linear laser outside the width according to the width of the core roll. The driving member 104 is installed on the baffle 103 for moving the baffle 103 according to the change in the width of the core roll. The second detection component 11 is installed together with the first detection component 10.

[0065] A portion of the linear laser emitted by the laser emitter 101 will be intercepted by the shielding plate 103, while the unshielded linear laser will irradiate the core coil below the laser emitter 101. The driving member 104 adjusts the position of the shielding plate 103 according to the winding speed of the strip to ensure that the unshielded linear laser is completely irradiated on the core coil. When the core coil below the laser emitter 101 has curling edges, the width of the strip will be reduced, so a portion of the linear laser will irradiate the laser detector 102. Depending on whether there is feedback from the laser detector 102, it is detected whether there is curling before the core coil is finally wound, so as to improve the quality of the final winding of the core coil. In this embodiment, the driving member 104 is an electric telescopic rod, which is a preferred embodiment of this embodiment. In other embodiments, the driving member 104 may be an electronic telescopic pump, etc.

[0066] Reference Figure 6 , the ends of the first material distribution transmission roller group 8, the first material discharge roller group 91 and the second material discharge roller group 92 away from the feeder 4 are all installed with a fixed plate 12, a telescopic slot is opened on the fixed plate 12, a telescopic plate 13 is installed in the telescopic slot, and an elastic member is installed between the bottom wall of the telescopic slot and the telescopic plate 13. The fixed plate 12 and the telescopic plate 13 can reduce the hanging length of the end of the core coil, thereby further facilitating the winding of the core coil and improving the winding quality. In this embodiment, the lower surface of the telescopic plate 13 is installed at an angle, and the closer to the mounting plate 51, the smaller the cross-sectional area, thereby ensuring that the fixed roller 552 can be staggered with the telescopic plate 13 through the lower surface of the telescopic plate 13 installed at an angle when rotating. In this embodiment, the elastic member is a spring, and the spring is a preferred embodiment of this embodiment. In other embodiments, the elastic member and are elastic rubber strips, etc.

[0067] The implementation principle of the automatic unloading double-station winding machine for amorphous three-dimensional iron core in the embodiment of the present application is as follows:

[0068] When it is necessary to automatically load the material cutting machine 4, the material discharging motor is started, and the material discharging motor drives the iron core roll on the material discharging roller to rotate. During the rotation of the iron core roll, the end of the iron core roll will naturally droop and enter between the first end transfer roller 31 and the second end transfer roller 32. The driving motor 341 drives the screw rod 342 to rotate. Since the screw rod 342 is threadedly connected to the moving block 343, the moving block 343 can be driven to move. During the movement of the moving block 343, the swing block 345 is driven to move synchronously through the connecting rod 344. When the swing block 345 is located in the wide section groove 351, the semi-elliptical end and the semi-circular end are on the same vertical line. At this time, the first end transfer roller 31 and the second end transfer roller 32 are in a straight line. The first and second end transfer rollers 31 and 32 are on the same horizontal line. When the swing block 345 is about to enter the narrow section groove 352, since the width of the narrow section groove 352 is set to be the same as the diameter of the semicircular end, and the moving block 343 continues to move the swing block 345 through the connecting rod 344, the swing block 345 will rotate ninety degrees, and at the same time drive the first end transfer roller 31 and the second end transfer roller 32 to swing ninety degrees toward the transmission component 33. At this time, the first end transfer roller 31 and the second end transfer roller 32 are on the same vertical line, so as to realize the swinging of the first end transfer roller 31 and the second end transfer roller 32, and realize the mutual meshing of the driving gear 348 and the driven gear 349, thereby realizing automatic feeding of the cutting machine 4;

[0069] When it is necessary to automatically unwind the split core roll, the end of the split core roll passes through the downward bend between the moving roller 551 and the fixed roller 552 and is sucked and grabbed by the negative pressure hole 543. When the core roll wound on the winding roller 53 becomes thicker and thicker, the moving roller 551 is pushed to move toward the fixed roller 552. When the other end of the split core roll is located between the moving roller 551 and the fixed roller 552, the moving roller 551 and the fixed roller 552 are just in a position to limit and clamp the other end of the split core roll. Multiple winding rollers 53, unwinding components 54 and tail fixings 55 can realize unwinding and winding the split core roll while unwinding another core roll that has been unwound and wound, thereby further improving the final winding efficiency of the core roll.

[0070] When it is necessary to detect whether there is curling before the core coil after material separation is finally wound up, a part of the linear laser emitted by the laser emitter 101 will be intercepted by the shielding plate 103, and the linear laser that is not blocked will be irradiated on the core coil strip below the laser emitter 101. The driving member 104 adjusts the position of the shielding plate 103 according to the winding speed of the strip to ensure that the linear laser that is not blocked is completely irradiated on the core coil strip. When the core coil strip below the laser emitter 101 has curling, the width of the strip will be reduced, so a part of the linear laser will be irradiated on the laser detector 102. According to whether there is feedback from the laser detector 102, it is detected whether there is curling before the core coil strip is finally wound up, so as to improve the quality of the final winding of the core coil strip.
