Double-station vacuum forming box

Abstract

The invention discloses a double-station vacuum forming box which comprises a double-station feeding mechanism and two vacuum forming boxes, wherein the double-station feeding mechanism continuously conveys materials to be formed to the two vacuum forming boxes in a transversely moving mode; the two vacuum forming boxes can realize continuous joint work; and the material forming packaging efficiency can be greatly improved. The double-station vacuum forming box comprises a double-station feeding mechanism, two top baffle plate mechanisms, an installing plate and two vacuum forming boxes in sequential arrangement from top to bottom; the two-station feeding mechanism comprises a feeding device with two vertical material passages and a transverse moving component used for transversely movingthe feeding device; the two top baffle plate mechanisms are matched with the vacuum forming boxes to be used; each top baffle plate mechanism comprises a baffle plate and a baffle plate moving component; and each vacuum forming box comprises an outer box body fixed under the installing plate, a rotating plate mechanism arranged at the bottom of the outer box body, and a transverse sealing component, an upper pressing component, a lateral pressing component and a bottom plate in sequential arrangement in the outer box body from top to bottom.

Description

technical field [0001] The invention relates to the technical field of packaging machines, in particular to a double-station vacuum forming box. Background technique [0002] The packaging machine is a machine that uses packaging bags to package products, which plays the role of protection and beauty. [0003] Vacuum packaging machine is a kind of packaging machine. The vacuum packaging machine can automatically extract the air in the packaging bag, and complete the sealing process after reaching the predetermined vacuum degree. Vacuum packaging machines are often used in the food industry, because after vacuum packaging, food can resist oxidation, so as to achieve the purpose of long-term preservation. In the prior art, the vacuum packaging machines are all designed with a single vacuum forming box, that is, the existing vacuum packaging machines can only complete the vacuum packaging of one material at a time, which has the defect of low efficiency. In addition, for the ...

Problems solved by technology

In the prior art, the vacuum packaging machines are all designed with a single vacuum forming box, that is, the existing vacuum packaging machines can only complete the vacuum packaging of one material at a time, which has the defect of low efficiency

In addition, for the packaged products of bricks, the packaged products packaged by the existing vacuum packaging machine have a bulge on the top, that is, there will be a conical bulge on the top, which is formed by the natural accumulation of materials when they fall, resulting in Products packaged by vacuum packaging machines have defects of insufficient aesthetics
