Forming device and packaging machine comprising forming device

Abstract

The invention relates to the technical field of packaging machines, in particular to a forming device and a packaging machine comprising the forming device. The forming device comprises a negative pressure pipeline, a bundling mechanism and a swing mechanism. One end of the bundling mechanism is provided with a groove assembly used for fixing and keeping a sealing film to be of an arc-shaped structure, and the other end of the bundling mechanism is rotatably connected with the swing mechanism; the swing mechanism is used for driving the bundling mechanism to swing back and forth; and the forming device is arranged on the packaging machine. The forming device and the packaging machine comprising the forming device are convenient to install, easy and convenient to debug, simple in process and convenient to machine, and the productivity is improved. PVDC films are used for outer packaging of the product, packaging treatment is convenient, and environmental pollution is reduced. A preforming material is changed into a PVDC sealing film from a traditional aluminum wire, stress of a forming die in the forming process is reduced, abrasion of the forming die is reduced, and the service life of the forming die is prolonged.

Description

technical field [0001] The present invention relates to the technical field of packaging machines, in particular to a molding device and a packaging machine containing the molding device. Background technique [0002] The forming device of the existing automatic vertical filling and packaging machine is composed of multiple parts, the processing technology is complicated, and the installation is complicated. The existing sealing and forming device is a product that is sealed by an aluminum wire, and the pre-formed material is an aluminum wire. During the forming process of the aluminum wire, the forming die bears a large impact force, and sliding friction occurs between the forming die and the aluminum wire. The service life is short, and one kind of forming mold corresponds to one kind of aluminum buckle. When replacing the forming mold, the replacement and debugging time is long, which reduces the production efficiency and increases the production cost. Because the moldin...

Problems solved by technology

[0003] The first purpose of the present invention is to provide a molding device, which can solve the problem that children are at risk in the process of eating through the metal detector using the aluminum wire buckle molding device method, using PVDC (PVDC is plastic) material The sealing film (the sealing film is a small piece of PVDC material) replaces the aluminum wire buckle forming device for ligation and sealing;

[0004] The second purpose of the present invention is to provide a packaging machine system, which aims to solve the problem of the existing aluminum buckle, which takes a long time to replace and debug when changing the forming mold, which reduces the production efficiency, causes sliding friction between the forming mold and the aluminum wire, and shortens the life of the forming mold. short question
