Then, when the hot cutter 4 cuts the woven bag, the stepper motor 10 drives the transmission shaft 11 to rotate, and the rotation of the transmission shaft 11 drives the gear 12 on the transmission shaft 11 to rotate. Then, due to the meshing of the two gears 12, the other gear 12 revolves around the gear 12 on the transmission shaft 11, and then the gear 12 on the movable column 15 drives the linkage rod 14 to rotate, and then when the linkage rod 14 rotates, through the existence of the limit bar 36, it drives the sliding block 17 to move in the slide groove of the limit bar 36, and drives the scraper block 24 through the sliding block 17 to clean the liquefied woven bag residue attached to the hot cutter 4.

When the scraping bar 27 needs to be replaced, the scraping bar 27 is replaced by contacting the clamping state of the clamping bar 28 and the hot cutting bar 26. When the woven bag is cut, the linkage motor 31 is started, and then the rotation of the linkage motor 31 drives the rotating column 32 to rotate, and then the several pushing blocks 34 on the rotating column 32 temporarily fix the woven bag. When the cutting is completed, the cut woven bag is moved away by the pushing block 34.
