Multi-functional automatic paper bag machine using touch screen operation, with step fixed length, photoelectric tracking, automatic counting, automatic punching and other industrial control devices. At the same time, in order to further achieve the effect of energy saving and environmental protection, in the production process with the residual material recovery function, the production process of bag-making waste automatically collected, help to secondary utilization, reduce labor intensity, increase work efficiency. The machine only needs 1-2 people to operate, and can adjust the production speed and product size within a certain range. The working principle of the automatic non-woven bag making machine is to use high frequency oscillation by the welding head to transmit sound waves to the welding surface of the working object, instantly causing friction to the working object molecules, so as to complete the rapid dissolution of solid materials, fully automated production, easy operation, and can maximize the solution to human operation. We believe that with the improvement of science and technology, we will be able to produce more convenient and intelligent equipment.
