Description
Technical Field
The utility model relates to the technical field of aluminum foil yin-yang composite bag processing equipment, in particular to novel color-printed aluminum foil yin-yang composite bag processing equipment.
Background
In recent years, aluminum foil yin-yang composite bags emerging in the field of soft plastic packaging and manufacturing are increasingly accepted and accepted by markets due to the advantages of novel material configuration, light resistance and content visibility, so that a lot of products (such as meat products and the like) needing to be stored and transported in a light-proof manner and displaying the content on a shelf are packaged by the aluminum foil yin-yang composite bags in the markets at present.
As shown in fig. 1, the traditional aluminum foil yin-yang composite bag mainly comprises two parts in terms of material configuration: the light-resistant side 11 containing the aluminum foil and the non-aluminum foil side 12, the light-resistant side containing the aluminum foil is generally referred to as the "female side" or "back side" of the bag, and the other side not containing the aluminum foil is generally referred to as the "male side" or "front side" of the bag.
The two surfaces of the aluminum foil yin-yang composite bag are both generally made of multi-layer materials through gluing and compounding processes, the shade surface of the bag used for avoiding light contains a layer of extremely thin aluminum foil material, and typical combinations are as follows: mylar/aluminum foil/polypropylene film, the other side of the bag is at least partially visible to the contents and therefore does not contain aluminum foil material, typically in the combination: polyester film/polyamide film/polypropylene film. The aluminum foil is the best material with light resistance and high barrier property used in the field of soft plastic packaging at present, the aluminum foil is not transparent and the aluminum atoms are densely arranged, so that water and oxygen molecules in the external environment of the packaging are difficult to permeate, the aluminum foil has excellent water and oxygen barrier property, and the quality guarantee period of contents can be greatly prolonged. The composite film containing the aluminum foil is used as one surface of the bag, so that the barrier property of the whole bag can be improved, and the requirement of light-proof storage and transportation of goods can be met.
The traditional aluminum foil yin-yang composite bag is manufactured by respectively manufacturing materials required by the yin and yang surfaces of the bag into independent coiled materials, then respectively unreeling the coiled materials by a bag making machine, and then carrying out heat sealing and cutting processes. As shown in fig. 2, during bag making, the female side material of the bag is placed on an aluminum foil composite film unwinding frame 21, the male side material of the bag is placed on two unwinding frames 22, passes through a bag making traction roller 23, is pressed by a bag making heat sealing ironing knife 24, and is finally cut into bags by a bag making cutter 25.
At present, the traditional processing and manufacturing mode of the aluminum foil yin-yang composite bag has obvious defects or limitations. This limitation is highlighted by: because the materials forming the male and female surfaces of the bag belong to different unreels, and the unreeling tension control systems are independent respectively (the tension is the force which must be added on the composite film to realize smooth feeding), the materials on the upper and lower surfaces are extremely difficult to completely synchronize for a long time in the bag making traction and feeding processes, and small displacement errors can be gradually accumulated to unacceptable levels along with the bag making process when the independent tension controls the feeding.
The limitation of the manufacturing method is finally reflected in the defect that the industrial stable production cannot be realized for the packaging products (for example, the bag has the pattern on the positive surface and the pattern on the negative surface and the bar code on the bar code) of which the negative and positive surfaces are designed with color printing patterns and the patterns on the two surfaces are required to be in one-to-one correspondence and strict alignment. Therefore, most of aluminum foil yin-yang composite bags in the market at present are blank bags without printing or color-printed bags with only one pattern, so that the market application of the aluminum foil yin-yang composite bags is limited.
