Description

technical field [0001] The invention relates to the technical field of food packaging bag manufacturing equipment, in particular to a bag making machine. Background technique [0002] The bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is plastic or other material packaging bags with different sizes, thicknesses and specifications. Generally speaking, plastic packaging bags are the main products. [0003] The eight-side sealing bag is composed of the front, the back, two sides and the bottom surface. When in use, the eight-side sealing bag can be opened to form a cuboid structure, which greatly increases its internal capacity, and when used in shopping places such as supermarkets, It can stand up after being opened, which is convenient for displaying products to customers; therefore, eight-side seal bags are widely used in many commodities, but the existing eight-side seal bag production line is...

Problems solved by technology

[0003] The eight-side seal bag is composed of the front, the back, two sides and the bottom surface. When in use, the eight-side seal bag can be opened to form a cuboid structure, which greatly increases its internal capacity, and when used in shopping places such as supermarkets, It can stand up after opening, which is convenient for displaying products to customers; therefore, eight-side sealing bags are widely used in many commodities, but the existing eight-side sealing bag production line is relatively single, and cannot be adjusted according to the size of the sealing bag, making the application There are certain limitations, and when cutting the envelope to form the front and back, the envelope may often be offset, resulting in unreliable cutting, making the front and back of the final envelope not aligned, affecting product quality
