Automatic Continuous Bag Type Modified Atmosphere Packaging Machine

Abstract

The invention relates to a fully-automatic continuous bag type modified atmosphere packaging machine. The packaging machine comprises a machine frame, wherein a feeding chain is arranged on the machine frame, a set of air pipe connectors and a set of air pipe fixing devices are arranged on the machine frame symmetrical about the feeding chain, gas replacement mechanisms are installed on the air pipe fixing devices respectively, one end of each gas replacement mechanism is communicated with the corresponding air pipe connector, and the other end of each gas replacement mechanism extends into a packaging cavity. The packaging machine is simple in structure and quick and convenient to install, movement of the gas replacement mechanisms in the left-right directions, up-down directions and front-back directions can be effectively achieved due to the arrangement of the air pipe fixing devices, so that modified atmosphere packaging requirements of different products are met, and adjustment is flexible, quick and convenient. Due to the arrangement of the air pipe connectors, inflation of an inflation pipe and exhaust of an exhaust pipe can be achieved at the same time, and in this way, replacement speed of gas in the packaging cavity is high, the replacement rate is high, and gas mixing precision is high.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a fully automatic continuous bag-type modified atmosphere packaging machine. Background technique [0002] At present, there are two main gas replacement methods for bag-type modified atmosphere packaging machines on the market: one is the vacuum inflation type, and its working process is to vacuumize the packaging bag first and then pour protective gas into the packaging, although this gas replacement form can be Higher gas replacement accuracy is obtained, but it is difficult to realize the continuous packaging process, and the packaging operation efficiency is low; the other is the flushing type, that is, a single tube is used to directly inject prefabricated gas into the packaging to discharge the original gas in the packaging to a certain extent. The effect of gas adjustment can realize continuous operation, but its replacement accuracy is low, it is difficult to achieve accurate gas c...

[0002] At present, there are two main gas replacement methods for bag-type modified atmosphere packaging machines on the market: one is the vacuum inflation type, and its working process is to vacuumize the packaging bag first and then pour protective gas into the packaging, although this gas replacement form can be Higher gas replacement accuracy is obtained, but it is difficult to realize the continuous packaging process, and the packaging operation efficiency is low; the other is the flushing type, that is, a single tube is used to directly inject prefabricated gas into the packaging to discharge the original gas in the packaging to a certain extent. The effect of gas adjustment can realize continuous operation, but its replacement accuracy is low, it is difficult to achieve accurate gas composition in the package, and it cannot meet the product packaging that requires high precision of gas composition in the package.

In the actual production process, the disadvantages of the two methods will cause certain restrictions on the production and application of the company's products
