The clamping post 17 penetrates and is slidably connected to the right side of the inner surface of the connecting member 15, enabling the clamping post 17 to move horizontally along the inner surface of the connecting member 15. A clamping groove A16 is provided on the left side of the outer surface of the support frame 1, enabling the rear end of the clamping post 17 to be clamped to the outer surface of the support frame 1. The rear end of the outer surface of the clamping post 17 is clamped to the clamping groove A16, enabling the connecting member 15 and the tension roller 4 to be clamped through the rear end of the clamping post 17 and the clamping groove A16 and fixed at a specified position. One end of a spring A11 is fixedly connected to the top of the outer surface of a column 9, and the other end of the spring A11 is fixedly connected to the inner surface of a tool holder 5, enabling the column 9 to drive a wedge block 12 to move upward through the elastic force of the spring A11 when the clamping block 13 is rotated into a vertical groove 202, releasing the fixation between the tool holder 5 and a tool roller 3. One end of the spring B18 is fixedly connected to the outer surface of the clamping post 17, and the other end of the spring B18 is fixedly connected to the right side of the inner surface of the connecting member 15, enabling the clamping post 17 to move outward through the elastic force of the spring B18 and be clamped to the clamping groove A16 when the pulling of the clamping post 17 stops.

[0041] Refer to Figure 6 , Figure 8 - Figure 9The T-shaped groove 20 includes a clamping groove 201, a vertical groove 202, and an annular groove 203. The outer surface of the clamping block 13 is clamped with the inner surface of the clamping groove 201, so that when the clamping block 13 is clamped with the clamping groove 201, the column 9 and the wedge block 12 can be fixed at the specified position. The outer surface of the clamping block 13 is slidably connected with the inner surface of the vertical groove 202, so that when the clamping block 13 is rotated to the position of the vertical groove 202, it can move vertically along the inner surface of the vertical groove 202 and drive the wedge block 12 to move upward, releasing the effect of clamping with the clamping groove B19. The outer surface of the clamping block 13 is rotatably connected with the inner surface of the annular groove 203, so that when the clamping block 13 moves into the annular groove 203, it can rotate to adjust the position of the clamping block 13.

[0042] Reference Figure 1 - Figure 2 The outer surface of the slitting auxiliary roller 7 is in contact with the cast film 2, so that the cast film 2 can move along the outer surface of the slitting auxiliary roller 7. The middle part of the outer surface of the cast film 2 is in contact with the outer surface of the tension roller 4, so that the tension roller 4 can control the cast film 2 after slitting. The bottom end of the inner surface of the support frame 1 is rotatably connected to the receiving roller 6, so that the receiving roller 6 can rotate along the bottom end of the inner surface of the support frame 1. The outer surface of the receiving roller 6 is fixedly connected to the barrel 8, and the outer surface of the barrel 8 is in contact with the cast film 2, so that when the receiving roller 6 rotates, it can drive the barrel 8 to receive the cast film 2.

[0043] Working principle: When using the device, first guide the large roll of cast film 2 between the annular cutter 10 and the slitting auxiliary roller 7, so that the annular cutter 10 cuts the cast film 2 into the required width, and then pulls the cut cast film 2 to the barrel 8 on the receiving roller 6 to collect the cut cast film 2.

[0044] When it is necessary to adjust the width of the slit cast film 2, first stop the device, then press down the cylinder 9 first, so that it drives the clamping block 13 and the wedge block 12 to move downward, release the clamping of the clamping block 13 and the clamping groove 201, and make the clamping block 13 move into the annular groove 203. Then rotate the cylinder 9 to drive the two groups of clamping blocks 13 to move into the vertical groove 202. Then release the cylinder 9, so that it moves upward due to the elastic force of the spring A11 and drives the wedge block 12 to move together. When the wedge block 12 moves upward to the specified position, the fixing of the tool holder 5 and the tool roller 3 will be released. Then push the tool holder 5 to the left or right to drive the annular tool 10 to move together. When it moves to the specified position, first press the cylinder 9 to drive the clamping block 13 and the wedge block 12 to move downward at the same time, so that the clamping block 13 moves into the annular groove 203, and the wedge block 12 is clamped with the clamping groove B19. Then rotate the cylinder 9 to drive the clamping block 13 to rotate to directly below the clamping groove 201. Then release the cylinder 9, so that the cylinder 9 drives the clamping block 13 to move upward due to the elastic force of the spring A11 and is clamped with the clamping groove 201, and the wedge block 12 always remains clamped with the clamping groove B19, fixing the tool holder 5 and the annular tool 10 at the specified position. Then adjust the other group of tool holders 5 to the appropriate position in the above manner, so as to achieve the effect of adjusting the slit width.

[0045] When it is necessary to adjust the tension of the slit cast film 2, first pull the clamping column 17 outward to release its clamping with the clamping groove A16, and at the same time release the fixing of the connecting piece 15 and the tension roller 4. Then move the connecting piece 15 upward or downward to drive the tension roller 4 to move together, so that the tension roller 4 increases or decreases the extrusion of the surface of the cast film 2. When it moves to the specified position, release the clamping column 17, so that it moves inward due to the elastic force of the spring B18 and is clamped with the clamping groove A16, fixing the connecting piece 15 and the tension roller 4 at the specified position, so as to achieve the effect of adjusting the tension of the slit cast film 2.
