The cutting blade 10 can pass through the cutting groove 8, so that the cutting blade 10 can contact the self-adhesive waterproof coiled material after passing through the coil pressing plate 7 to achieve cutting. A motor 111 in the scraper assembly 11 is fixedly connected to an outer wall of one side of the coil pressing plate 7 by bolts. There are two motors 111 in total, and the two motors 111 are symmetrically arranged on an outer wall of one side of the coil pressing plate 7. The motor 111 is fixedly connected with a ball screw 112 through an output end on one side thereof. A nut seat on the ball screw 112 is fixedly connected with a connecting rod 113 through a nut.

A cutting groove 12 is provided at the top center of the cutting base 2.

[0024] It should be noted that, due to the uneven cutting of existing self-adhesive waterproof membranes, sticking occurs during cutting, and a large amount of glue adheres to the cutter, causing subsequent cutting to be obstructed.
