Continuous box type gas regulation packaging machine

Abstract

The invention discloses a continuous box type gas regulation packaging machine, comprising a conveying transmission system used for conveying boxes, a packaging system used for sealing the boxes and a transmission and control system, wherein the packaging system comprises a gas replacing mechanism used for replacing gas in the box and a heat sealing mechanism used for sealing the box after the gas is replaced, and the transmission and control system is used for rolling and releasing a heat sealing thin film for the packaging system. The continuous box type gas regulation packaging machine provided by the invention has simple structure, continuous automation gas regulation packaging can be carried out on wrappage in a box type structure, main operations such as gas replacing, box sealing and film cutting are completed on the same station, the integral structure is compact, the production space is saved, the transfer time on a production line is saved; the gas replacing accuracy and thegas mixing accuracy in a packaging box are high; and multiple boxes can be simultaneously packaged, and the packaging speed is fast.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a continuous box-type modified atmosphere packaging machine, which belongs to the technical field of packaging. Background technique [0002] At present, fresh-keeping packaging in food and other fields has gradually developed from vacuum packaging to modified atmosphere packaging, that is, other inert gases are used to replace the air in the food packaging box. Modified atmosphere packaging has many advantages that traditional vacuum packaging cannot match. Fast and high productivity, but the current modified atmosphere packaging machines also have some areas that need to be improved, such as simple modified atmosphere packaging machines can only work in one step, and the packaging efficiency is low; the structure of modified atmosphere packaging machines that can operate continuously and automatically Gas, box sealing, film cutting and other operations generally require several stations t...

[0002] At present, fresh-keeping packaging in food and other fields has gradually developed from vacuum packaging to modified atmosphere packaging, that is, other inert gases are used to replace the air in the food packaging box. Modified atmosphere packaging has many advantages that traditional vacuum packaging cannot match. Fast and high productivity, but the current modified atmosphere packaging machines also have some areas that need to be improved, such as simple modified atmosphere packaging machines can only work in a single step, and the packaging efficiency is low; Gas, box sealing, film cutting and other operations generally require several stations to complete, the equipment work line is long, and the required work space is large
