Full-automatic continuous box type gas-control packing device

Abstract

The invention relates to a completely automatic continuous box-typed air conditioning packaging machine, which is characterized in that operations of vacuum pumping, inflating and box packaging are respectively completed on two continuous working positions; an air replacing device comprises a sealing chamber which is connected with a cylinder shaft; a sealing chamber is internally provided with the air replacing device which respectively carries out the air pumping and inflating of the air replacing chamber by an external pumping pipeline and an inflating pipeline; the external inflating pipeline is arranged on an air conditioning auxiliary device which carries out the conditioning of the air in the box by the external inflating pipeline; a thermal sealing film guiding device and the air conditioning auxiliary device are connected on a frame; the thermal sealing device is fixedly connected with the frame by a connecting screw; a first film cutting device and a second film cutting device are respectively arranged on the frame. The completely automatic continuous box-typed air conditioning packaging machine has high air replacing rate and air mixing precision and quick packaging speed, meets the requirements of changed volume of the packaging products and various styles of exterior of the packaging boxes, and has the advantages of integrating the sealing and slicing into a whole, etc.

Description

technical field [0001] The invention relates to a fully automatic continuous box-type modified atmosphere packaging machine, in particular to a modified atmosphere packaging machine with rapid gas replacement and functions of sealing and cutting, belonging to the technical field of modified atmosphere packaging machinery and equipment . Background technique [0002] In the prior art, there are currently two gas replacement and operation methods for box-packed modified atmosphere packaging machines on the market: one is to place the packaging box containing the product in a closed cavity, first vacuumize it, and then fill it with pre-filled air. Configure the gas, and then seal the box. The above operation process is completed at the same station; the second is to adopt the gas flushing replacement, that is, the packaging box containing the product is placed in the working chamber, and the pre-configured gas is used to directly flush the inside of the box. Exhaust the origin...

AI Technical Summary

Problems solved by technology

The two have their own advantages and disadvantages. The first method can obtain a higher gas replacement rate and gas mixing accuracy, but since the three operations of vacuuming, inflation, and sealing are completed at the same station, the equipment has a longer working cycle , the production speed is low; in the second method, because the vacuum operation is not used, the gas replacement is faster and the productivity is higher, but the gas replacement rate and gas mixing accuracy are low, which affects the freshness of the product.

In the actual production process, the disadvantages of the two methods have caused certain restrictions on the production and application of product companies.
