Problems solved by technology

[0006] During the packaging process of the packaging machine, when the material is unloaded in the packaging bag, the air will enter the bag with the material, affecting the residual oxygen in the packaging bag. At the same time, during the movement of the packaging bag, it will also cause air The entry of air affects the residual oxygen in the bag, thus affecting the storage of materials in the bag

Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the processing technology of the packaging machine to reduce the residual oxygen content includes the following steps:

[0026] Transport the packaging bag to the bag opening station, and fill the bag with nitrogen; the packaging bag is conveyed to the bag opening station under the action of the conveying device, and the bag is filled with nitrogen to replace the air in the bag for the first time after opening , before the packaging bag is transported to the bag opening station, the packaging bag can be made into a roll film bag or a prefabricated bag. Since the mass of nitrogen is less than that of air when it is filled with nitrogen, during the movement, Nitrogen gas will move upwards, thereby leaving the packaging bag, so that the packaging bag needs to be filled with nitrogen several times, and the bag opening sta...

Abstract

The invention relates to a processing technology for reducing residual oxygen for a packaging machine. The processing technology comprises the following steps that A, the packaging bag is transportedto a bag opening station, and the packaging bag is filled with nitrogen; B, the packaging bag is transported to a discharging station, and the packaging bag is filled with nitrogen after discharging;C, the packaging bag is transported to a bag unfolding station, and the packaging bag is filled with nitrogen; and D, heat seal is carried out on the packaging bag, and then cold seal is carried out.Compared with the prior art, through three times of nitrogen filling, it is ensured that the residual oxygen in the packaging bag is within the standard range, the packaging bag has been opened and closed after three times of nitrogen filling, the nitrogen in the packaging bag is isolated from outside air, and therefore the heat seal and cold seal enable the nitrogen in the packaging bag to be more stable.

Description

technical field [0001] The invention belongs to the technical field of packaging machines, and in particular relates to a processing technology for packaging machines to reduce residual oxygen. Background technique [0002] The packaging machine is a kind of product packaging and it plays the role of protection and beauty. The packaging machine is used to produce packaging products in an assembly line, and it is a kind of packaging equipment around the product. [0003] With the development of social economy, more and more customers have requirements on the residual oxygen content of food. For the modified atmosphere packaging of cooked food, the control of residual oxygen is very important. The principle of modified atmosphere packaging of cooked food is mainly It replaces the oxygen in the air and then injects a certain proportion of carbon dioxide and nitrogen mixed gas or 100% nitrogen into the packaging box to isolate the oxygen and prevent the oxidation reaction of the...
