A mounting seat 5 is fixedly connected to the output end of the hydraulic cylinder 4. A motor 6 is fixedly connected to one side of the mounting seat 5. The output shaft of the motor 6 is fixedly connected to a connecting shaft 8 through a coupling.

[0028] A limiting ring 9 is movably connected to the outer wall of the connecting shaft 8, and a cutter 10 is movably connected to the outer wall of the connecting shaft 8. A positioning post 11 is fixedly connected to one side of the cutter 10.

A support frame 16 is fixedly connected to one side of the support 1. When it is necessary to disassemble and replace the cutter 10, the mounting base 5 can be driven upward by the hydraulic cylinder 4, so that the limiting ring 9 can be moved away from the support frame 16. This facilitates the improvement of the operating space, makes it easy to disassemble the first clamping ring 12 and the second clamping ring 13 from the connecting shaft 8, and disassemble the limiting ring 9 from the connecting shaft 8, thereby facilitating the quick disassembly and replacement of the cutter 10 and improving the convenience of operation.

[0029] In this embodiment, a support block 7 is fixedly connected to the top of the mounting base 5, and a support seat 17 and a fixing block 18 are fixedly connected to the top of the support frame 16 respectively. A rotating shaft 19 is fixedly connected to the front of the fixing block 18, and a protective cover 20 is movably connected to one end of the rotating shaft 19. A post 21 is fixedly connected to the inner wall of the protective cover 20, which can place the protective cover 20 on the mounting base 5, thereby isolating the cutter 10 and avoiding safety hazards when cutting plastic film. This effectively improves the safety of processing operations and reduces the occurrence of accidents.

[0030] Example 2

[0031] Based on Embodiment 1, a preferred embodiment of the high-speed slitting device for plastic film processing with easy-to-change blades provided by this utility model is, for example... Figures 1 to 5 As shown: The top of the support block 7 has a slot, and the inner wall of the slot is movably connected to one end of the insertion post 21. The support block 7 is movably connected to the insertion post 21 through the slot, which can support and position the protective cover 20, thereby enabling the protective cover 20 to provide stable protection.

[0032] In this embodiment, a rubber sleeve is fixedly connected to the inner wall of the limiting ring 9, and the limiting ring 9 is movably connected to the connecting shaft 8 through the rubber sleeve. The outer wall of the limiting ring 9 is movably connected to the inner wall of the support base 17, which facilitates the stable installation of the limiting ring 9 outside the connecting shaft 8 and improves the tightness between the limiting ring 9 and the connecting shaft 8.

[0033] Furthermore, one end of the fastening rod 15 extends through the top of the first clamping ring 12 and the top of the second clamping ring 13 and into the screw ring 14. The outer wall of the fastening rod 15 is threaded, and the fastening rod 15 is threaded to the screw ring 14, which can connect and install the first clamping ring 12 and the second clamping ring 13, so that it can be stably installed outside the connecting shaft 8 to position the cutter 10, and at the same time, it also brings convenience to the later disassembly.

[0034] Furthermore, an alignment groove is provided on one side of the first clamping ring 12, and the inner wall of the alignment groove is movably connected to the outer wall of the positioning post 11. The first clamping ring 12 is movably connected to the positioning post 11 through the alignment groove, which enables the first clamping ring 12 to be stably connected to the cutter 10, thereby improving the connectivity between the structures.

[0035] In addition, the protective cover 20 is movably connected to the fixed block 18 via the rotating shaft 19, and the protective cover 20 is a transparent arc-shaped protective cover, which can effectively isolate it from the cutter 10, thereby improving the safety during processing.

[0036] In use, first pull the protective cover 20 upward to separate the bottom insert 21 from the support block 7. Then, through the cooperation of the rotating shaft 19, the protective cover 20 can be flipped and rotated away from the cutter 10. Then, start the hydraulic cylinder 4 to drive the mounting base 5 to move upward, thereby driving the motor 6 and the connecting shaft 8 to rise synchronously, and moving the limit ring 9 away from the support seat 17 on the support frame 16, providing operating space for subsequent disassembly of the cutter. Then, pull the limit ring 9 out of the connecting shaft 8, rotate the fastening rod 15 to disengage it from the screw ring 14 and at the same time separate it from the second clamping ring 13 and the first clamping ring 12, so that the second clamping ring 13 can be disassembled. Then, pull the first clamping ring 12 to one side to separate it from the positioning post 11 on one side of the cutter 10. Then, the cutter 10 can be disassembled from the connecting shaft 8, which is convenient for replacement and maintenance.

[0037] In summary, this high-speed slitting device for plastic film processing, which facilitates tool replacement, increases the operating space when the cutter 10 needs to be disassembled and replaced. It facilitates the removal of the first clamping ring 12 and the second clamping ring 13 from the connecting shaft 8, and the removal of the limiting ring 9 from the connecting shaft 8, thereby enabling quick disassembly and replacement of the cutter 10. The protective cover 20 can be placed on the mounting base 5 to isolate the cutter 10, avoiding safety hazards during plastic film slitting and effectively improving the safety of the processing operation.
