The design of the adjusting wheel 10 enables the operator to adjust the position of the fixed cutter 6 through a simple rotation action without the need for complex tools or professional knowledge, thereby greatly simplifying the operation process.

The drive motor 13 is arranged on the mounting base 1, and the two groups of conveying rollers 11 are connected through a transmission assembly. A clamping assembly is correspondingly provided at the conveying rollers 11; the drive motor 13 directly drives one group of conveying rollers 11, and the other group of conveying rollers 11 is connected through the transmission assembly. This design ensures the consistency and controllability of the conveying speed, and helps to accurately control the conveying speed of the material. By setting two groups of conveying rollers 11, the materials at the two groups of fixed cutters 6 can be continuously conveyed respectively. The setting of the auxiliary part 12 provides rotation support for the two groups of conveying rollers 11, and the material is stably conveyed by following the rotation of the conveying rollers 11 through the clamping assembly.

The design of the isolation member 17 places the two sets of transmission gears 14 in a closed space, effectively preventing the entry of external impurities and extending the service life of the transmission assembly.

[0030] like Figures 1 to 4As shown, as a preferred solution, the clamping assembly includes a mobile frame 18 that is slidably arranged in the positioning groove of the mounting member 2, and a clamping roller 19 is rotatably arranged on the mobile frame 18.

The material is placed on the conveying roller 11 and is stably conveyed by the clamping roller 19 of the clamping assembly to avoid sliding or offset. The drive motor 13 is started and the two sets of conveying rollers 11 are driven to operate synchronously through the transmission assembly. When the material reaches the predetermined position, the cylinder 5 drives the mobile cutter 4 to move along the track on the mounting base 1 and cooperates with the fixed cutter 6 to perform cutting operations.
