Description

Technical Field

[0001] The invention relates to the field of food packaging, in particular to food packaging paper and a packaging device and a packaging method for the packaging paper. Background Art

[0002] Existing solid food packaging, such as instant noodles, candies, etc., mostly uses plastic materials, which is not environmentally friendly, and most of the inside is fully coated with glue, which wastes resources. Moreover, after sealing, a separate setting is required to replace the cutting mechanism to separate the sealed packaging bags, which increases time and equipment costs and is inefficient.

[0003] Therefore, those skilled in the art provide food packaging paper and a packaging device and a packaging method for the packaging paper to solve the problems raised in the above background technology. Summary of the invention

[0008] As a further solution of the present invention: the middle isolation glue layer and the edge glue layer are made of food-grade hot-sealing glue or cold-sealing glue.

[0009] The packaging device of food packaging paper comprises a packaging pressing wheel 1 and a packaging pressing wheel 2 for pressing the packaging paper, arc grooves are provided on the side walls of the packaging pressing wheel 1 and the packaging pressing wheel 2, and edge pressing parts and head and tail pressing parts are respectively provided on the packaging pressing wheel 1 and the packaging pressing wheel 2 on both sides and ends of the arc groove, and wheel axles for installation are integrally formed at both ends of the packaging pressing wheel 1 and the packaging pressing wheel 2.

[0010] As a further solution of the present invention: a cutting support copper block is embedded and fixed in the middle of the head and tail pressing parts of the packaging pressing wheel one, and a cutting knife body is fixedly installed in the middle of the head and tail pressing parts of the packaging pressing wheel two.

[0011] As a further solution of the present invention: the edge pressing part of the packaging pressing wheel one and the packaging pressing wheel two is the same width as the edge glue layer, the head and tail pressing part width of the packaging pressing wheel one and the packaging pressing wheel two is the same width as the middle isolation glue layer, and the axial size of the upper edge pressing part of the packaging pressing wheel one and the packaging pressing wheel two is the same as the distance between the two middle isolation glue layers.

[0012] As a further solution of the present invention: when the middle isolation coating layer and the edge coating layer are made of food-grade cold sealing adhesive, a heating layer is embedded in the edge pressing part and the head and tail pressing part of the packaging pressing wheel 1 and the packaging pressing wheel 2.

[0013] The packaging method of food wrapping paper includes the following steps:

[0014] S101, gluing: applying edge glue layers on two edge portions of one side of the packaging paper, applying a middle isolation glue layer on the packaging paper at equal intervals along the direction of the edge glue layers, and winding the glued packaging paper on a winding wheel for standby use;

[0015] S102, paper placement: two winding wheels are arranged opposite to each other on the packaging machine, ensuring that the glue-coated surfaces of the packaging paper are opposite to each other after the packaging paper is unfolded, and the packaging paper is placed on the packaging pressing wheel 1 and the packaging pressing wheel 2;

[0016] S103, packaging: The food to be packaged is conveyed to the middle part of two packaging papers through a conveying device, and the edge glue layer and the middle isolation glue layer are adhered to each other by applying force by the packaging pressing wheel 1 and the packaging pressing wheel 2, so as to achieve packaging. In addition, the cutting knife body and the cutting support copper block cooperate to directly cut and separate the packaged food packaging bags.

[0017] Preferably, in step S101 and step S102, the edge pressing parts of packaging pressing wheel one and packaging pressing wheel two match the width dimension of the edge glue coating layer, the width of the head and tail pressing parts of packaging pressing wheel one and packaging pressing wheel two matches the width of the middle isolation glue coating layer, and the axial dimension of the upper edge pressing parts of packaging pressing wheel one and packaging pressing wheel two matches the distance between the two middle isolation glue coating layers.

[0018] Preferably, in step S103, when cold sealing adhesive is used, it can be directly bonded at home. When hot sealing adhesive is selected, the packaging pressing wheel 1 and the packaging pressing wheel 2 embedded with a heating layer are used to heat and press the sealing.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the present invention completes the pressing and sealing, the cutting knife body can realize the rapid cutting and separation of the connected packaging bags, eliminating the trouble of adding a cutting mechanism at the bottom separately, improving efficiency, saving costs, and greatly reducing the overall height of the device; it can ensure that the packaging of one packaging bag is completed when the packaging pressing wheel 1 and the packaging pressing wheel 2 rotate one circle. Through such an arrangement, the scope of the packaging paper glue layer can be greatly reduced, saving resources.

[0021] 2. The present invention adopts the method of applying hot-sealing glue or cold-sealing glue on the local bonding part of the packaging paper to replace the existing full coating, which is more cost-saving, and by using packaging paper or aluminum film paper instead of plastic materials, it is more environmentally friendly.
