An automatic liquid injection vacuum sealing machine

Abstract

The invention discloses an automatic liquid injection vacuum sealing machine, the structure of which comprises a sealing main machine, a control panel, a guide rail, a driver, a transmission plate, and a supporting base. The flow rod descends vertically inside the guide ring, and at the same time, through the guide flow of the inclined flow tube and the partition bar, the air bubbles generated during the milk injection process are reduced, and the needle pierces the air bubbles at the opening of the plastic bag to avoid the opening of the plastic bag There is a gap at the center to improve the airtightness of the milk in the plastic bag. During the movement of the two conflicting plates, the extrusion rod in the middle remains still, so that the sliding rod slides inside the sliding groove, so that the linkage rod pulls The lamination board is pulled into the top surface of the collision board, and the synchronous collision of the four lamination boards ensures that the opening of the plastic bag is kept neat, avoiding gaps at the opening of the plastic bag during the heat sealing process, and improving the airtightness of the milk in the plastic bag.

Description

technical field [0001] The invention relates to the field of vacuum sealing machines, more specifically, to an automatic liquid injection vacuum sealing machine. Background technique [0002] In the process of producing milk in plastic bags, it is necessary to use the automatic liquid injection vacuum sealing machine to inject milk, and then heat the opening of the plastic packaging bag by heating the heating plate on the automatic liquid injection vacuum sealing machine to a certain temperature Pressurization makes the opening of the plastic packaging bag tightly sealed, prolongs the shelf life of the milk, and ensures the quality of the milk. However, during the process of injecting milk into the plastic bag, the milk tends to generate air bubbles inside the plastic bag, and the bubbles rise and accumulate in the plastic packaging bag. At the opening, the opening of the plastic packaging bag is not neat. At this time, direct heating and pressure will easily cause a gap at ...

[0002] In the process of producing milk in plastic bags, it is necessary to use the automatic liquid injection vacuum sealing machine to inject milk, and then heat the opening of the plastic packaging bag by heating the heating plate on the automatic liquid injection vacuum sealing machine to a certain temperature Pressurization makes the opening of the plastic packaging bag tightly sealed, prolongs the shelf life of the milk, and ensures the quality of the milk. However, during the process of injecting milk into the plastic bag, the milk tends to generate air bubbles inside the plastic bag, and the bubbles rise and accumulate in the plastic packaging bag. At the opening, the opening of the plastic packaging bag is not neat. At this time, direct heating and pressure will easily cause a gap at the opening of the plastic packaging bag, resulting in leakage of the milk in the plastic bag after the sealing is completed, which reduces the sealing of the milk in the plastic bag. sex
