Mechanical, fully-automatic and intelligent vacuum packaging machine for non-particulate materials

Abstract

A mechanical, fully-automatic and intelligent vacuum packaging machine for non-particulate materials comprises a chassis, a feed hopper, a vibration feeding mechanism, a metering mechanism, a bag supplying device, a bag opening device, a bag filling mechanism, a bag sealing and cutting mechanism and a vacuum sealing device. A vacuum packaging device comprises a left cavity and a right cavity, wherein the left cavity and the right cavity are drawn together to form a vacuum chamber; a sealing component used for sealing a packaging bag under the conditions of high temperature and hot pressing isarranged at the upper side of an inner cavity of the vacuum chamber; the middle part of the inner cavity of the vacuum chamber is provided with an anti-sticking positioning device used for positioning and clamping the packaging bag; the anti-sticking positioning device comprises a frame body seat; the two lower side parts of the frame body seat are respectively provided with a positioning shaft in a penetrating way; a pair of supporting plates that can be drawn together in a crossing way so as to support the lower part of the packaging bag are articulated on the two positioning shafts; channels for the crossing of the two supporting plates are arranged on the supporting plates at intervals; the supporting plates are positioned under the frame body seat; and a pair of clamping plates that can be drawn together oppositely so as to clamp the upper part of the packaging bag are articulated on the two positioning shafts in an inner cavity of the frame body seat.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a mechanical fully automatic non-granule intelligent vacuum packaging machine. Background technique [0002] Vacuum packaging technology originated in the 1940s. In 1950, polyester and polyethylene plastic films were successfully used in vacuum packaging, and since then, vacuum packaging has developed rapidly. my country's vacuum packaging technology was developed in the early 1980s, and the vacuum inflation packaging technology was used in small quantities in the early 1990s. With the promotion of small packages and the development of supermarkets, its scope of application has become wider and wider. Some will gradually replace rigid packaging. [0003] After decades of development, vacuum packaging equipment still has many technical defects. For example, during heat sealing, the packaging bag is easy to stick to the heat sealing rod, and the material cannot be dropped norma...

AI Technical Summary

Problems solved by technology

For example, during heat sealing, the packaging bag is easy to stick to the heat sealing rod, and the material cannot be dropped normally, which affects the normal production

As another example, the sealing assembly of the existing packaging equipment includes two relatively moving sealing rods, and the driving mechanism of the sealing rods is separated, that is, each sealing rod has its own cylinder drive, which not only wastes resources, but also increases The volume of the mechanism makes the whole mechanism complex and the reliability of operation is low
