Inside the top plate 202, the top plate 202 is provided with a round hole adapted to the rotating rod 310, the rotating rod 310 is rotatably connected to the pressing plate 304, two sets of springs 305 are installed on the upper surface of the pressing plate 304, a cutter group 308 is engaged between the upper limit block 306 and the lower limit block 301, and fixing holes 302 adapted to the insertion rod 309 are provided at both ends of the cutter group 308, and the lifting ring 307 is pulled upward, and the lifting ring 307 moves upward to drive the upper limit block 306 After the upper limit block 306 is lifted up, the upper limit block 306 moves upward, driving the insertion rod 309 to disengage the fixing hole 302. When the upper limit block 306 moves upward, it drives the rotating rod 310 to move upward. The rotating rod 310 moves upward, driving the pressure plate 304 to move upward. The pressure plate 304 moves upward and compresses the spring 305. When the bottom of the upper limit block 306 reaches the top of the top plate 202, the upper limit block 306 is rotated 180°. At this time, the upper limit block 306 does not block the cutter group 308 from moving upward. The cutter group 308 is then taken out upward, the cutter group 308 is polished or replaced, and the cutter group 308 is placed in the lower limit hole 303 of the lower limit block 301 to complete the initial limit, and ensure that the fixing hole 302 is facing upward, and then the upper limit block 306 is rotated 180° to return to its original position. Driven by the rebound of the spring 305, the upper limit hole 311 is driven to clamp the cutter group 308, and the insertion rod 309 is driven to clamp the fixing hole 302.

[0027] Working principle: When the double-sided adhesive mother roll is actually cut, different fixing rods 7 are installed according to the diameter of the axial hole of the mother roll, and the screw 13 at the end of the fixing rod 7 is aligned with the threaded hole 12 and screwed in to complete the installation, and then the mother roll is sleeved on the outside of the fixing rod 7, and one end of the mother roll is pressed against the limit plate 9, and then the fixing plate 14 is used to press the other end of the mother roll (different fixing rods 7 are adapted to different fixing plates 14), and the fixing bolt 15 is used to fix the fixing plate 14;

[0028] At this time, the pushing component 2 is started, and the electric telescopic rod 204 is started to drive the push plate 203 to move horizontally in the direction of the fixed rod 7. The push plate 203 moves horizontally to drive the slide plate 206 to slide along the slide groove 6. The slide plate 206 moves to drive the top plate 202 to move horizontally. The top plate 202 moves horizontally to drive the cutting group 308 to completely cut into the mother roll until the blade contacts the fixed rod 7 (different cutting groups 308 are replaced according to production needs). At this time, the mother roll is cut, and then the motor 10 is started. The motor 10 starts to drive the connecting rod 11 to rotate. The rotation of the connecting rod 11 drives the limit plate 9 to rotate. The rotation of the limit plate 9 drives the fixed rod 7 to rotate. The rotation of the fixed rod 7 drives the mother roll to rotate. The mother roll rotates, and the cutting group 308 completes the slitting of the mother roll. The cutting group 308 can be used to split multiple groups at a time to improve production efficiency.

[0029] When the blade of the cutter group 308 is blunt and needs to be polished or replaced, or when the cutter group 308 is replaced according to the double-sided tape of different production widths (the production widths of the double-sided tape are different, and the commonly used widths are 0.5 cm, 1 cm, and 2 cm), pull the lifting ring 307 upward, the lifting ring 307 moves upward to drive the upper limit block 306 to move upward, the upper limit block 306 moves upward to drive the insertion rod 309 to disengage from the fixing hole 302, and the upper limit block 306 moves upward to drive the rotating rod 310 to move upward, and the rotating rod 310 moves upward to drive the pressure plate 304 to move upward, and the pressure plate 304 moves upward to compress the spring 305. When the bottom of the upper limit block 306 reaches the top of the top plate 202, the upper limit block 306 is rotated 180°. At this time, the upper limit block 306 does not block the cutter group 308 from moving upward. The cutter group 308 is then taken out upward, the cutter group 308 is polished or replaced, and the cutter group 308 is placed in the lower limit hole 303 of the lower limit block 301 to complete the initial limit, and ensure that the fixing hole 302 is facing upward. The upper limit block 306 is then rotated 180° to return to its original position. Driven by the rebound of the spring 305, the upper limit hole 311 is driven to clamp the cutter group 308, and the insertion rod 309 is driven to clamp the fixing hole 302.
