A food vacuum packaging machine

Abstract

The invention belongs to the field of food mechanical processing, in particular to an intelligent food vacuum packaging machine which comprises a machine body. The machine body comprises an upper cover and a lower cover which are rotationally connected. An air extracting device and a circuit board are arranged inside the machine body, the upper cover is provided with an upper vacuum cavity, the lower cover is provided with a lower vacuum cavity, the side close to an opening of the lower cover is provided with a fixing mechanism, the fixing mechanism comprises a plurality of positioning bucklesdriven by a driving mechanism, the lower vacuum cavity is divided by a partition plate into independent small vacuum cavities, air nozzles are arranged in the small vacuum cavities correspondingly, the air nozzles communicate with a vacuum pump through air extracting pipes correspondingly, the upper vacuum cavity is provided with a sealing groove corresponding to the partition plate, and the partition plate extends upwards and is inserted into the sealing groove. The existing vacuum machine technology is adopted in an integrated mode, multi-package continuous operation is added on the basis of reserving existing technological advantages, the air extracting intensity can be adjusted according to the size of objects to be packaged, and therefore the purpose of saving energy is achieved.

Description

technical field [0001] The invention belongs to the field of food mechanical processing, in particular to a food vacuum packaging machine. Background technique [0002] At present, with the accelerated pace of daily life, the abundance of nutritious and health food, healthy diet and quality of life have become the focus of attention. Every family has endless fresh vegetables and fruits every day, and improper storage will lose the original nutrition and water; everyone has endless snacks every day, and they are always troubled about how to store half-eaten snacks. Some people have the habit of collecting precious calligraphy, paintings, photos, and jewelry, but if they are not properly preserved, they are easily oxidized, causing discoloration and mildew. Therefore, their packaging and storage is particularly important, and the vacuum packaging machine just solves the problems that many families are very concerned about.

AI Technical Summary

Problems solved by technology

[0003] There are two typical types of vacuum packaging machines commonly found in the market. One is as disclosed in CN202193231U or CN205221203U. This type of vacuum machine is easier to operate and can realize multi-package operations. The disadvantage is that the flow rate of the vacuum chamber is fixed and cannot be based on The flow rate of the items to be processed is adjusted. In addition, since there is no fixed mechanism during multi-package operation, it is easy to deviate; the other is disclosed in CN201670372U. The mouth goes directly into the bag to be sealed, so the air extraction is more thorough, the freshness preservation effect is better, and the machine life is relatively longer, but the flow rate of this vacuum machine is also not adjustable, and it cannot perform multi-pack operation
