A connecting rod 55 is connected to one end of the take-up drum 9. A turntable 26 is installed at one end of the connecting rod 55. The turntable 26 rotates through the other switching frame 8. A drive structure is provided on one of the housings 2. The second clamping structure includes a groove 54 formed in the middle of the side of the transfer plate 14 away from the vertical plate 12. Two rotating shafts 19 are rotatably connected between the two sides of the groove 54. A flipping block 20 is rotatably sleeved on each rotating shaft 19. A torsion spring is connected between the flipping block 20 and the groove wall of the groove 54. A clamping strip 21 is installed at one end of each flipping block 20. A through groove 15 is formed on the transfer plate 14 near the groove 54. A first electric push rod 16 is installed on one side of the through groove 15. The output shaft of the first electric push rod 16 is inserted into the groove 54 and one end is connected to a pull rod 17. An extrusion strip 18 is installed at one end of the pull rod 17. The extrusion strip 18 is located between the two flipping blocks 20. The first clamping structure includes an inner groove 22 opened on the upper and lower sides of the first through groove 11, a clamping plate 23 is movably inserted into the inner groove 22, a fourth through groove is opened on the side of the inner groove 22 near the turntable 26, a driving plate 24 is movably passed through the fourth through groove, and a driving structure is provided on the turntable 26. The driving structure includes a second electric push rod 27 installed on one side of the turntable 26. One end of the output shaft of the second electric push rod 27 is connected to a U-shaped frame 28. The U-shaped frame 28 moves through a second through slot 29 opened on the turntable 26. A driving slot 25 is opened on the driving plate 24. A through rod 30 is fixedly passed through the U-shaped frame 28. The through rod 30 moves through the driving slot 25. The slitting structure includes a fixing strip 52 connected to the second fixing plate 50, two sets of guide rods 31 rotatably arranged between the two fixing strips 52, a guide cylinder 32 fixedly sleeved on each guide rod 31, a mounting plate 33 fastened between the two fixing strips 52 by bolts, a second motor 34 mounted on the rear side of the mounting plate 33, a rotating rod 35 rotatably connected between the inner walls of the front and rear sides of the mounting plate 33, a plurality of slitting blades 36 equally spaced on the rotating rod 35, and the output shaft of the second motor 34 connected to one end of the rotating rod 35; The drive structure includes an L-shaped plate 37 fastened to one of the housings 2, a fourth motor 38 mounted on the L-shaped plate 37, a first gear 39 sleeved on the output shaft of the fourth motor 38, and a second gear 40 fixedly sleeved at one end of one of the rotating drums 6. The second gear 40 meshes with the first gear 39. First, the first motor 10 is started to drive the take-up drum 9 to rotate, and the rotating take-up drum 9 winds up the slit insulating paper. At the same time, the second motor 34 on the mounting plate 33 is started to drive the rotating rod 35 and the slitting blade 36 to rotate, slitting the insulating paper between the two sets of guide cylinders 32, and the insulating paper is cut from... Three winding drums 51 pass through to ensure the insulation remains taut during the slitting process, thus guaranteeing slitting quality. When one set of winding drums 9 finishes winding and another set needs to be replaced for slitting, the insulation paper is first cut. After cutting, the fourth motor 38 on the L-shaped plate 37 is activated, which drives the switching frame 8 to rotate via the first gear 39 and the second gear 40, switching the other set of winding drums 9 to the winding position. Then, the cylinder 13 on the vertical plate 12 is activated to move the transfer plate 14 towards the fixed strip 52. When the transfer plate 14 passes through the first winding drum 9... When the through slot 11 moves the clamping strip 21 to the remaining insulating paper, the first electric push rod 16 in the through slot 15 is activated, causing the extrusion strip 18 to move away from the slitting blade 36. During the movement, the extrusion strip 18 squeezes the two flipping blocks 20, pushing the flipping blocks 20 to rotate on the rotating shaft 19, causing the clamping strip 21 to clamp the cut insulating paper. Then, the first electric push rod 16 causes the clamped insulating paper to move in the opposite direction, pulling the insulating paper through the first through slot 11 in the opposite direction. At this time, the second electric push rod 27 on the turntable 26 is activated, causing the U-shaped frame 28 to move through the second through slot 29. The moving part of the plate 24 drives the through rod 30 to move in the drive groove 25 of the drive plate 24. By squeezing the groove wall of the drive groove 25 with the through rod 30, the two clamping plates 23 are moved closer to each other in the first through groove 11, clamping the insulating paper in the first through groove 11. Then, the insulating paper is released between the clamping strips 21, so that the cut multiple strips of insulating paper are directly pulled into the take-up drum 9 for clamping and fixing. Then, the corresponding first motor 10 is started to drive the take-up drum 9 to rotate, so that the cutting of insulating paper can continue. The operation is more labor-saving, convenient and efficient.

[0019] See Figure 10 and Figure 11The cutting structure includes two vertical slots 42 on the T-shaped plate 41, with a screw 43 passing through each slot 42. The two screws 43 in each group are fixedly connected, and the upper and lower threads of the screw 43 are in opposite directions. A third motor 44 is installed at the top of the T-shaped plate 41, and the bottom of the output shaft of the third motor 44 is connected to one of the upper screws 43. Lifting blocks 53 are slidably arranged at both ends of each vertical slot 42. The lifting blocks 53 have threaded slots for the screws 43 to pass through. Lifting plates 45 are connected between the lifting blocks 53 on the two T-shaped plates 41. Cutting blades 46 are arranged on one side of each pair of lifting plates 45 that are close to each other. A third clamping structure is arranged on the lifting plates 45. The third clamping structure includes an H-shaped plate 48 mounted on a lifting plate 45. A third through slot 47 is provided on the lifting plate 45 for the H-shaped plate 48 to move through. A spring 49 connects the H-shaped plate 48 and the lifting plate 45. During cutting, the third motor 44 on the T-shaped plate 41 is activated to drive two sets of screws 43 to rotate. Each set of lifting blocks 53 moves towards each other, causing the lifting plate 45 to move. During the movement, the lifting plate 45 drives the corresponding H-shaped plate 48 to clamp onto the insulating paper. Then, the lifting plate 45 continues to move, driving the cutting blade 46 to move and cut the insulating paper. After cutting, the lifting plate 45 moves in the opposite direction, removing the cutting blade 46 from the insulating paper. At this time, the remaining insulating paper is still clamped between the H-shaped plates 48, allowing the clamping strip 21 to smoothly clamp the insulating paper between the H-shaped plates 48 and transfer it to the take-up drum 9.

[0020] The implementation principle of the insulating paper slitting mechanism in this embodiment of the invention is as follows: First, the first motor 10 is started to drive the winding drum 9 to rotate. The rotating winding drum 9 winds up the slit insulating paper. At the same time, the second motor 34 on the mounting plate 33 is started to drive the rotating rod 35 and the slitting blade 36 to rotate, slitting the insulating paper between the two sets of guide cylinders 32. The insulating paper passes through the three winding cylinders 51, which ensures that the insulating paper is in a taut state during the slitting process, thereby ensuring the slitting quality. When one set of winding drums 9 finishes winding and it is necessary to replace it with another set of winding drums 9 to continue the slitting work, firstly, the third motor 44 on the T-shaped plate 41 is started to drive the two sets of screws 43 to rotate. Each set of lifting blocks 53 moves towards each other, causing the lifting plate 45 to move. During the movement, the lifting plate 45 causes the corresponding H-shaped plate 48 to clamp onto the insulating paper. Then, the lifting plate 45 continues to move, causing the cutting blade 46 to move and cut the insulating paper. After cutting, the lifting plate 45 moves in the opposite direction, removing the cutting blade 46 from the insulating paper. At this time, the remaining insulating paper is still clamped between the H-shaped plates 48. Then, the fourth motor 38 on the L-shaped plate 37 is started, which drives the switching frame 8 to rotate through the first gear 39 and the second gear 40, switching another set of take-up drums 9 to the take-up position. Then, the cylinder 13 on the vertical plate 12 is started, which drives the transfer plate 14 to move towards the fixed bar 5. The process involves two movements. When the transfer plate 14 passes through the first through slot 11 on the take-up drum 9, it moves the clamping strip 21 to the insulating paper between the H-shaped plates 48. The first electric push rod 16 in the through slot 15 then moves the extrusion strip 18 away from the slitting blade 36. During this movement, the extrusion strip 18 presses against the two flipping blocks 20, causing them to rotate on the rotating shaft 19. This causes the clamping strip 21 to clamp the cut insulating paper. Then, the lifting plate 45 continues to move, moving the H-shaped plates 48 back to their original position. After the insulating paper is released between the H-shaped plates 48, the first electric push rod 16 moves the clamped insulating paper in the opposite direction, pulling it back through the first through slot 11. At this point, the process begins... The second electric push rod 27 on the rotating turntable 26 drives the U-shaped frame 28 to move in the second through groove 29, which in turn drives the through rod 30 to move in the drive groove 25 of the drive plate 24. By using the through rod 30 to squeeze the groove wall of the drive groove 25, the two clamping plates 23 are driven to move towards each other in the first through groove 11, clamping the insulating paper in the first through groove 11. Then, the insulating paper is released between the clamping strips 21, so that the cut multiple strips of insulating paper are directly pulled into the take-up drum 9 for clamping and fixing. Finally, the corresponding first motor 10 is started to drive the take-up drum 9 to rotate, so that the cutting of insulating paper can continue. The operation is more labor-saving, convenient and efficient.

[0021] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
