By means of the drawing winding machine, the problems that existing drawing winding efficiency is low, and drawings can hardly be separated from winding rollers are solved.

The invention relates to a preparation process of a BOPP heat-sealing film for packaging bags, which mainly includes the following steps: raw material processing, extrusion operation, cooling corona, winding and slitting and other processes, and the used BOPP heat-sealing film slitting equipment. It includes an operating table, a roll feeding mechanism, a cutting mechanism and a rewinding mechanism. The left end of the operating table is provided with a roll feeding mechanism, a cutting mechanism is installed in the middle of the operating table, and a winding mechanism is installed on the right end of the operating table. The following problems exist in the slitting of BOPP heat-sealing film for packaging bags. First, the existing BOPP heat-sealing film for packaging bags needs to adjust the distance between the knives when slitting, but the traditional slitting mechanism is an integrated knife. It is more troublesome to replace the knives with different spacings, which reduces the slitting efficiency and quality of the BOPP heat-sealing film for packaging bags; 2. After the BOPP heat-sealing film for packaging bags is slit, it cannot be stably wound. It affects the winding efficiency and quality of BOPP heat-sealing film for packaging bags.
