Food packaging equipment and food packaging method

Abstract

The invention belongs to the technical field of packaging equipment, in particular to food packaging equipment and a food packaging method. The food packaging equipment comprises a high-temperature material barrel, a packaging film and a driving roller; the packaging film is wound on the outer surface of a plastic film roller; the free end of the packaging film is wound on the surface of the driving roller; a hard plastic film is arranged on the surface of the packaging film; three edges of the hard plastic film are pressed on the surface of the packaging film through hot pressing, and an opening is formed in the top of the hard plastic film; an auxiliary roller is arranged between the plastic film roller and the driving roller; the packaging film passes through the surface of the auxiliary roller; the auxiliary roller consists of two circular plates and a plurality of groups of iron rods; and the two circular plates are fixedly connected by the iron rods. According to the food packaging equipment and the food packaging method, the opening of the hard plastic film can be opened without an additional opening device, so that the process flow can be simplified; and meanwhile, hot airinside the high-temperature material barrel can heat a heat transfer plate through an elastic heat conduction pipe for heat sealing at the opening, so that an electric heating plate does not need to be used, and waste heat is recycled while the electric energy is saved.

Description

technical field [0001] The invention belongs to the technical field of packaging equipment, in particular to a food packaging equipment and a food packaging method thereof. Background technique [0002] Food packaging machine, in short, is a machine that packs and seals food so that it can be stored for a long time. The food packaging equipment in the prior art is generally composed of the following devices: conveying device, mouth opening device, feeding device and sealing device. Basically, it is necessary to stretch the packaging bag used for food packaging first, and then put the food into the packaging bag The inside of the box is then hot-pressed and sealed by an electric heating plate, and then the sealed packaging bag containing food is transported to the inside of the packaging box. Obviously, if the above-mentioned method is used for packaging, the process flow is more complicated. If Using higher automation machinery, because the mechanical equipment includes the...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, solve the complex packaging process of the prior art, the high price of the equipment caused by the opening device in the packaging equipment, and the lack of the opening device in the equipment leads to low production efficiency, and at the same time, the heat energy of roasted seeds and nuts can not be effectively used during packaging. The problem of utilization, a kind of food packaging equipment and food packaging method thereof that the present invention proposes
