Pillow type fresh food packaging machine

Pillow-type fresh food packaging machine, also known as bag forming-filling-sealing machine, uses a composite film to wrap the fresh food and then seals it to keep fresh. The schematic structure is shown in Figure 1. Fresh food packaging materials not only need to have a certain strength, but also need a certain barrier ability to prevent fresh food from deteriorating. Therefore, the packaging material is a composite film that integrates the superior properties of multiple materials, and the usual thickness is 35-80 μm. Pillow-type fresh food packaging machine is mainly composed of the following parts: feeding mechanism, film feeding mechanism, vertical sealing mechanism, horizontal sealing and transverse cutting mechanism. This type of packaging machine is generally a lower film type, feeding and film feeding are carried out at the same time, and the packaged fresh food is transported to the top of the composite film through the feeding mechanism. The composite film is folded upward through the folding film plate to be made into a cylindrical shape, and is longitudinally sealed by the heat-sealing roller in the longitudinal sealing mechanism, and at the same time provides power for the transportation of the film. The feeding mechanism is equipped with sensors to control the feeding speed. Since the packaging container containing the fresh food has a certain height, the transverse sealing and cutting mechanism is equipped with a cutting knife that moves up and down to cut the film. The cutting knife is connected with the heating element, and the heat sealing and film cutting are performed at the same time. The finished fresh food is packaged. It is sent to the collection box by the conveying mechanism.
