[0002] Bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is various sizes, thicknesses and specifications of plastic or other materials packaging bags. Generally speaking, plastic packaging bags are the main products.
[0003] In the process of processing and producing many films, the films need to be cut according to customized requirements. Most of the existing cutting equipment adjusts the cutting components through hydraulic rods or electric push rods. Although they can cut, the efficiency is relatively low and it is difficult to meet the requirements of automated production. At the same time, since most cutting equipment does not restrict the film during cutting, it is inevitable that the film will warp, etc., resulting in deviations in the cutting position.

The connecting plate is symmetrically fixed to the left and right ends of the cutting rod, and the connecting plate can be slid up and down along the inside of the limiting slide groove for adjustment.
[0011] Furthermore, a cutting knife set is arranged on the outer surface of the cutting rod, and the cutting knife set is connected to the cutting rod via bolts.
[0012] Furthermore, the adjustment mechanism includes an adjusting rod, an adjusting disk, a connecting gear, a driving gear and a servo motor. The adjusting rod is rotatably connected to one end of the cutting rod, the adjusting disk is rotatably connected to the other end of the adjusting rod, and the adjusting disk and the adjusting rod are eccentrically arranged. A connecting gear is fixed at the center of a side of the connecting gear away from the adjusting disk, the driving gear is meshed and connected to one side of the connecting gear, and the servo motor is fixed at the center position of one end of the driving gear.
