The threaded rod is rotatably mounted on the connecting block. One end of the threaded rod is located in the opening and is provided with a chuck. The other end of the threaded rod is located outside the connecting block. A limiting groove is provided in the opening and is located at the bottom of the connecting block. A clamping area for the tool holder shaft to pass through is formed between the chuck and the limiting groove. When the tool holder shaft is located in the clamping area, the slitting assembly can be mounted or disassembled on the tool holder shaft by rotating the threaded rod.

[0007] A movable groove is also arranged at one end of the connection block away from the opening, and the blade is movably connected in the movable groove.

[0008] In one embodiment, a screw bearing seat is provided at the bottom of the movable groove, and the slitting assembly also includes an adjusting component, which is located in the movable groove. The adjusting component includes a screw shaft and a slider, one end of the screw shaft is installed on the screw bearing seat, and the other end extends to the outside through the connecting block. The slider is movably connected to the screw shaft and connected to the blade. By rotating the screw shaft, the slider can move relatively in the movable groove, thereby driving the blade to move synchronously.

[0009] In one embodiment, the slitting assembly also includes a bolt, and the slider is also provided with a receiving groove and a screw hole, the receiving groove is located at the bottom of the slider, the screw hole is located on the side of the slider and is connected to the receiving groove, and a through hole is provided at the upper end of the blade, and the blade can be installed or removed on the slider through the cooperation of the bolt, the screw hole and the through hole.

[0010] In one embodiment, a knob is mounted on one end of the screw shaft outside the connection block.

[0028] Reference Figure 1-Figure 3A slitting device of a film casting machine comprises a frame 1, a knife frame shaft 2 arranged between the frames, a plurality of slitting components 3 arranged on the knife frame shaft 2, and a transmission roller 4 arranged between the frames 1 for transmitting materials, wherein the transmission roller 4 is located below the knife frame shaft 2, and a scale 41 is arranged on the transmission roller 4, which is conducive to an operator to accurately adjust the position corresponding to the blade 35, and the operation is more convenient, and the slitting component 3 is movably connected to the knife frame shaft 2, and the slitting component 3 is used to slitting and cutting a film;

[0029] The slitting assembly 3 includes a connecting block 31, a threaded rod 32 and a blade 35. One end of the connecting block 31 is provided with an opening 311, and the threaded rod 32 is rotatably mounted on the connecting block 31. One end of the threaded rod 32 is located in the opening and is provided with a clamping head 321. The other end of the threaded rod 32 is located outside the connecting block 31 and is provided with a rotating handle 322. A limiting groove 312 is provided in the opening 311 and is located at the bottom of the connecting block 31. Anti-slip paths are provided in the clamping head 321 and the limiting groove 312, so that the slitting assembly 3 is more stable during the slitting process and the production quality of the film is improved. A clamping area for the tool holder shaft 2 to pass through is formed between the clamping head 321 and the limiting groove 312. When the tool holder shaft 2 is located in the clamping area, the slitting assembly 3 can be quickly and conveniently installed or disassembled on the tool holder shaft 2 by rotating the threaded rod 32, thereby increasing the practicality of the slitting assembly 3 and effectively improving the production efficiency.

[0030] The end of the connecting block 31 away from the opening 311 is also provided with a movable groove 313, and a screw bearing seat is provided at the bottom of the movable groove 313. The slitting assembly 3 also includes an adjusting component 33, and the adjusting component 33 is located in the movable groove 313. The adjusting component 33 includes a screw shaft 331 and a slider 332. One end of the screw shaft 331 is installed on the screw bearing seat, and the other end extends to the outside through the connecting block 31 and is installed with a knob 3311. The operator can drive the screw shaft 331 to rotate by turning the knob 3311, which is convenient for the operator to quickly adjust, thereby improving the slitting assembly 3. In order to improve the performance of use, the slider 332 is movably connected to the screw shaft 331 and is connected to the blade 35. Through the knob 3311, the slider 332 can move relatively in the movable groove 313, thereby driving the blade 35 to move synchronously, and adjusting the distance between the blade 35 and the transmission roller 4 to meet the slitting requirements in various situations, thereby improving the practicality of the slitting device. When slitting is not required, it is only necessary to rotate the knob 3311 to adjust the position of the blade 35 upwards. There is no need to disassemble the slitting component 3. At the same time, the wear rate of the blade 44 is reduced, thereby effectively improving the production efficiency.

[0031] The cam 321 is then moved to the left of the tool holder 310 so that the tool 310 can be easily moved with the cam 321 being moved upwardly and downwardly.

[0032] In one embodiment, referring to Figure 1-Figure 3 The slitting assembly 3 also includes a bolt 34, and the slider 332 is also provided with a receiving groove 3321 and a screw hole 3322. The receiving groove 3321 is located at the bottom of the slider 332, and the screw hole 3322 is located on the side of the slider 332 and is connected to the receiving groove 3321. A through hole 351 is provided at the upper end of the blade 35, and the blade 35 is snapped into the receiving groove 3321. The bolt 34 passes through the screw hole 3322 and the through hole 351 to fix the blade 35 on the slider 332. This can effectively ensure the stability of the connection between the blade 35 and the slider 332 and prevent the blade 35 from falling off during the slitting process to affect the slitting effect. When the blade 35 needs to be adjusted or replaced, the blade 35 can be quickly and conveniently installed or removed, thereby improving the performance of the slitting device.
