Description
Technical Field
[0001] The utility model relates to the technical field of packaging bag production, in particular to a fixed-length cutting packaging bag making machine. Background Art
[0002] Food packaging is an integral part of food commodities and one of the main projects in the food industry. It protects food and prevents it from being damaged by biological, chemical, and physical external factors during the circulation process from the factory to the hands of consumers. It can also have the function of maintaining the stable quality of the food itself. It facilitates the consumption of food and is the first to show the appearance of food and attract consumers. It has value beyond material cost. Food packaging bags are a kind of packaging design. In order to facilitate the preservation and storage of food in life, product packaging bags are produced. When making packaging bags, the raw materials of the packaging bags need to be cut to a fixed length.
[0003] The existing fixed-length cutting packaging bag making machine drives the packaging bag raw material shaft to rotate through a motor, and cooperates with the motor to drive the crank-connecting rod mechanism to drive the cutting knife to reciprocate cutting, thereby realizing fixed-length cutting of the packaging bag raw materials. There are some problems. For example, in actual use, as the packaging bag raw material on the packaging bag raw material shaft is gradually consumed, the length of the packaging bag raw material extended after the packaging bag raw material shaft rotates one circle gradually decreases. The single-chip microcomputer is required to control the motor speed in real time. During the adjustment process, errors will inevitably occur. For this reason, we propose a fixed-length cutting packaging bag making machine. Utility Model Content
