Vertical packaging machine send membrane and encapsulation mechanism design
Abstract：Packer is a kind of processing equipment commonly used in modern industrial . According to the requirement of automatic candy packer, the overall mechanism design and calculation of the packer were accomplished in this paper. Both the functions of delivering and packaging were realized in this design, by which packaging and sealing were done in the process of food delivering.
The overall design scheme of vertical packer was carried out on the basic of the research on the conveying and packaging scheme. The chain wheel is driven by motor, the film is fed by the drum that is connected with chain wheel. The double reduction gearbox connected with the chain wheel is applied to medium sealing device.. To achieve end sealing process, the closing and opening of end seal heating device is realized through the process that the cylinder pushes a piece of plate to press another piece of plate.
Keywords: Packer; Gear reducer; medium seal; End seal; Transmission chain; Heating roller
