[0002] Automatic slitting machine is an important mechanical equipment that can cut roll materials by using cutting tools. It is widely used in packaging, printing, electronics, medical and other fields. In the production of PE plastic cast film, automatic slitting machine is usually used to achieve efficient slitting.

[0003] At present, when the PE plastic cast film automatic slitting machines on the market are in use, the positions of most tools are set to be fixed, and they lack adaptability to different cutting widths. Although the cutting width of some models can be adjusted manually, it is difficult to accurately control the cutting size of the tool, which affects the actual cutting quality. At the same time, the sharpness of the tool will gradually decrease due to wear during continuous use, and these models are more cumbersome when replacing the tools, which increases the workload of the staff. Therefore, in order to solve these problems, we need to consider designing an automatic PE plastic cast film slitting machine. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 5 A PE plastic cast film automatic slitting machine includes a workbench 1, a U-shaped support plate 2 is fixedly connected to the upper end of the workbench 1, four side plates 17 are fixedly connected to the upper end of the workbench 1, and two film pressing rollers 18 are rotatably connected between each two matching side plates 17. Each two matching film pressing rollers 18 are used to ensure the normal transportation of the cast film to ensure the smooth progress of the slitting operation;

[0022] Among them, it also includes a moving mechanism, which includes two electric telescopic rods 3 installed on the upper end of the U-shaped support plate 2, the telescopic ends of the two electric telescopic rods 3 are fixedly connected to the U-shaped support frame 4, and a motor 5 is installed on the right side of the U-shaped support frame 4. The motor 5 is a servo motor that can change the rotation direction. A bidirectional threaded rod 6 is rotatably connected between the left and right inner walls of the U-shaped support frame 4. The thread directions of the two threaded ends on the bidirectional threaded rod 6 are opposite. The right end of the bidirectional threaded rod 6 passes through the right side of the U-shaped support frame 4 and is fixedly connected to the output shaft of the motor 5. The two threaded ends of the bidirectional threaded rod 6 are threadedly connected with sliders 7. The upper ends of the two sliders 7 are fitted with the inner top of the U-shaped support frame 4, and the lower ends of the two sliders 7 are provided with mounting grooves 8.

[0023] Among them, it also includes two cutting assemblies, both of which are used to cut cast film and are easy to replace. The cutting assembly includes a mounting block 9 arranged in the mounting groove 8, the upper end of the mounting block 9 fits with the inner wall of the mounting groove 8, the upper end of the mounting block 9 is provided with a limiting through groove 10, and the lower end of the mounting block 9 is provided with a cutting blade 11. The front side of the slider 7 is provided with a circular connecting block 12, and the rear side of the circular connecting block 12 is fixedly connected to a limiting rod 13, which passes through the slider 7 and fits with the inner wall of the limiting through groove 10. By controlling the limiting rod 13 to pass through the limiting through groove 10, the mounting block 9 can be limited. The rear side of the circular connecting block 12 is fixedly connected with an annular permanent magnet 14. The front side of the slider 7 is made of iron and can be magnetically attracted to the annular permanent magnet 14, thereby ensuring the fixation of the circular connecting block 12 and the limiting rod 13;

[0024] Among them, the front sides of the two sliders 7 are fixedly connected with pointers 15, and the front side of the U-shaped support frame 4 is provided with scale lines 16. The scale lines 16 cooperate with the two pointers 15 to facilitate the staff to intuitively understand the current cutting width and ensure the actual cutting accuracy.

[0025] In the utility model, when in use, the staff first controls the motor 5 to drive the bidirectional threaded rod 6 to rotate, and drives the two sliders 7, the two mounting blocks 9, the two cutting blades 11, and the two pointers 15 to move horizontally. During this period, by observing the movement of the two pointers 15 in conjunction with the scale lines 16, the staff can intuitively understand the current cutting width until the specified cutting width is reached. The cast film to be cut is then passed through between the two lamination rollers 18 on the rear side, the inner side of the U-shaped support plate 2, and the two lamination rollers 18 on the front side and continuously transported. During the transportation process, the two electric telescopic rods 3 are controlled to drive the U-shaped support frame 4 to move downward, and drive the two sliders 7, the two mounting blocks 9, and the two cutting blades 11 to move downward synchronously, so that the lower ends of the two cutting blades 11 will contact the cast film and cut it. The entire cutting process can meet the needs of different cutting widths with high accuracy, thereby ensuring the quality of cutting.

[0026] It is worth mentioning that when the cutting blade 11 needs to be replaced, the staff can hold the mounting block 9 at the upper end of the cutting blade 11 that needs to be replaced, and then pull out the circular connecting block 12 on the front side of the mounting block 9 forward, driving the corresponding limit rod 13 to move out to cancel the limit on the mounting block 9. At this time, the cutting blade 11 can be removed, and then the mounting block 9 at the upper end of the new cutting blade 11 can be aligned with the mounting slot 8 and inserted. After it is fully inserted, the limit rod 13 is controlled to pass through the limit slot 10 on the mounting block 9, and at the same time cooperate with the annular permanent magnet 14 to fix the circular connecting block 12. In this way, the cutting blade 11 can be conveniently replaced, and the cutting efficiency of the cutting blade 11 is guaranteed.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
