Then, the electric push rod 301 is extended to drive the transmission roller 204 located above to descend, clamping the sheet between the upper and lower transmission rollers 204. At this time, the cylinder 203 acts downward to drive the cutter 202 to accurately cut the sheet. After cutting, the first motor is started to drive the transmission roller 204 located below to rotate, continuously and stably pushing the clamped sheet into the fixed frame 2. Through this process, the continuous cutting of the sheet is realized, effectively improving the processing efficiency and reducing manual intervention, thereby improving the cutting effect of the device.

[0024] In the embodiment, guide grooves 303 are formed in the inner walls of the fixed frame 2, and sliding blocks 304 are fixed to the two sides of the movable plate 201.
