During use, the bottom end of the connecting rod 15 pulls the upper and lower seat 21 to slide up and down along the bottom end of the positioning seat 24, so that the cutting tool 23 moves up and down to realize the cutting of the fabric.

[0041] The integrated roller sewing machine with belt cutting directly installs the motor 12 at the end of the drive shaft 13 by using the fixed seat 11. The output end of the motor 12 is directly connected to the drive shaft 13. During driving, the response speed is fast, reducing the problems of high cost, difficult maintenance, and low transmission efficiency caused by complex transmission. At the same time, a plurality of groups of positioning and mounting holes 16 are provided on the outer surface of the end of the drive shaft 13 and the guiding crank 14. The drive shaft 13 and the guiding crank 14 are fixedly installed by screws passing through the positioning and mounting holes 16, so that the entire crank transmission part is assembled by multiple parts, reducing the difficulty of production and manufacturing. At the same time, when partial damage occurs later, only corresponding replacement is required, reducing the replacement cost.
