[0002] With the development of economy and the adjustment of rural industrial structure, the market demand for plastic films in various industries in China is increasing. Among them, polyurethane film is becoming more and more popular due to its superior performance and environmental protection concept. Polyurethane film manufacturers often need to cut the films out of the sound field to meet the different width requirements of different customers, so slitting equipment is needed.

[0003] When adjusting the cutter position of the existing co-extruded film production online slitting device, the operator needs to manually unscrew the fastening screws. After unscrewing the screws, in order to ensure the accuracy of the cutter position, the operator usually needs to use a ruler or measuring tool for precise measurement. This measurement process is not only cumbersome, but also easily affected by human errors. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an online slitting device for co-extruded film production to solve the technical problem that operators usually need to use rulers and measuring equipment for measurement, which is relatively time-consuming.

[0017] Furthermore, a conveying roller group is arranged on one side of the pressure roller, and a feeding roller is arranged on one side of the conveying roller group.

[0018] By adopting the above technical solution, by arranging a conveying roller group on one side of the pressure roller, smooth transmission of the film before and after slitting can be ensured. The conveying roller group can effectively guide and support the film to prevent it from deflecting or wrinkling during transmission, thereby improving production efficiency and product quality.

[0019] Furthermore, a locking hole and a guide hole are provided on the left mounting seat, and a locking pin is provided inside the locking hole.

[0021] Furthermore, a pull rod is slidably connected inside the guide hole, and one end of the pull rod is fixedly connected via a connecting block and a locking pin.

[0022] By adopting the above technical solution, a simple and effective locking and unlocking mechanism is achieved by sliding a pull rod inside the guide hole and fixing one end of the pull rod with a connecting block and a locking pin, so that the operator can easily control the position of the locking pin through the pull rod, thereby locking or unlocking the cutter mechanism.

[0023] Furthermore, the other end of the pull rod is rotatably connected to the locking cam via a connecting frame.

[0024] By adopting the above technical solution, the other end of the pull rod is rotatably connected to the locking cam through the connecting frame, so that the rotation of the locking cam can directly control the linear movement of the pull rod, thereby controlling the insertion or extraction of the locking pin.

At the same time, the left mounting seat 1021 and the right mounting seat 1022 are firmly connected by bolts to ensure the overall rigidity of the cutter mechanism 102, so that high-precision slitting operations can be performed to achieve continuous and efficient production line operation.

[0038] See also Figure 1 , Figure 2 and Figure 3 A scale line 1025 is provided at one end of the hollow extension rod 1024. By providing the scale line 1025 at one end of the hollow extension rod 1024, an intuitive reference is provided for the operator, so that they can adjust the position of the cutter mechanism 102 more accurately, improve the slitting accuracy, reduce human errors, and thus ensure the consistency of the size of the slit film. At the same time, the setting of the scale line 1025 also greatly simplifies the adjustment process, reduces the time for repeated tests and measurements, and improves production efficiency. The operator only needs to adjust according to the position indicated by the scale line to quickly and accurately position the cutter mechanism 102, making the device easier to use and more efficient.

[0039] See also Figure 1 , Figure 2 and Figure 3 A groove 103 is provided on the sliding rod 101, and a threaded hole 1026 is provided on the left mounting seat 1021. By providing the groove 103 on the sliding rod 101, a stable sliding track is provided for the cutter mechanism 102, ensuring the stability and accuracy of the cutter mechanism during movement, making the adjustment of the cutter mechanism 102 smoother.

At the same time, the operator can easily lock or unlock the cutter mechanism through the locking pin 8, so as to facilitate position adjustment or maintenance, which not only improves the usability of the equipment, but also greatly enhances its safety and reliability.

[0046] See also Figure 4 and Figure 5A pull rod 9 is slidably connected inside the guide hole 7, and one end of the pull rod 9 is fixedly connected to the locking pin 8 through a connecting block 10.

At the same time, when the locking pin 8 is inserted into the locking hole 6, it can firmly lock the cutter mechanism 102 on the sliding rod 101 to prevent it from moving during operation.

[0047] See also Figure 4 and Figure 5 The other end of the pull rod 9 is rotatably connected to the locking cam 12 through the connecting frame 11, so that the rotation of the locking cam 12 can directly control the linear movement of the pull rod 9, and then control the insertion or extraction of the locking pin 8. By rotating the locking cam 12, the cutting mechanism 102 can be easily locked or unlocked, and the operation is simple and quick.

[0048] The implementation principle of the utility model is: first, when the cutter mechanism 102 needs to be loosened, the locking cam 12 is pulled upwards. At this time, the locking force between the locking pin 8 and the groove 103 is reduced, so that the cutter mechanism 102 can move freely. When locking is required, the locking cam 12 is locked. The locking cam 12 drives the locking pin 8 and the groove 103 to be pressed together through the connecting frame 11 and the pull rod 9, thereby completing the quick locking of the cutter mechanism 102.
