Vacuum packaging equipment based on folding forming of bottom film container and novel packaging box

Abstract

The vacuum packaging equipment comprises a base and a supporting frame fixedly installed on the base, the end, close to the top, of the supporting frame is provided with a discharging roller, the other end, close to the top, of the supporting frame is provided with a discharging roller, and a film body belt is connected between the discharging roller and a collecting roller. A folding mechanism used for container packaging forming is installed in the middle of the supporting frame, one end of the film body belt is fixedly connected to the outer wall of the discharging roller, and the other end of the film body belt penetrates through the folding mechanism, extends to the outer wall of the collecting roller and is fixedly connected with the collecting roller. Through the structure and principle design of the folding mechanism, a packaging box with a bottom folding and top sealing structure can be automatically formed, adverse effects such as wrinkles and local thinning of the formed container wall are effectively avoided, the surface printing and code spraying process is facilitated, and meanwhile the high ornamental degree is achieved.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a vacuum packaging device and a novel packaging box based on the folding and forming of a bottom film container. Background technique [0002] The common snack foods on the market are generally packaged by prefabricating small bags, manually opening the bag for filling, vacuuming and heat-sealing, or by thermoforming the film into an open-bottom container, filling materials, and vacuuming and heat-sealing. It also affects the hygiene and safety of food; the current vacuum packaging equipment based on the bottom film container folding and forming, and the equipment with the bottom folding function, in the packaging process, there are many steps, requiring manual filling of items, opening prefabricated bags, sealing, etc., work The efficiency is low, it is inconvenient to realize integral molding, and the equipment without bottom folding function is stretched by thermoforming thr...

Problems solved by technology

Moreover, it affects the hygiene and safety of food; the current vacuum packaging equipment based on the folding of the bottom film container, the equipment with the bottom folding function, in the packaging process, there are many steps, and the items need to be manually filled, and the prefabricated bags need to be opened and sealed when working. The efficiency is low, it is inconvenient to realize integral molding, and the equipment without the bottom folding function, through the thermoforming and stretching of the film, the formed container wall will be wrinkled and partially thinned, which is not beautiful
