AI Technical Summary

Technical Problem

When existing vacuum packaging machines deal with humidity items or items with liquid, they can easily cause the liquid in the packaging bag to flow into the vacuum chamber and pipes, causing liquid residue and mold in the pipes, which will affect the safety of the equipment.

Method used

A vacuum packaging machine that can extract liquid is designed. A solenoid valve is used to control the connection state between the vacuum chamber and the vacuum pump. The gas in the vacuum chamber is extracted through the first pipe, and the external gas is introduced through the second pipe to adjust the air pressure value of the vacuum chamber to avoid liquid flow. At the same time, the residual liquid in the first pipe is blown into the vacuum chamber by using the solenoid valve to reduce the residual liquid in the pipe.

Benefits of technology

It effectively avoids the flow of liquid into the vacuum chamber and pipe during vacuum packaging, reduces the risk of liquid residue and mold in the pipeline, and improves the safety and service life of the equipment.

Abstract

The utility model relates to a vacuum packaging machine capable of pumping liquid, which comprises a vacuum cavity, the vacuum cavity is connected with a first interface of an electromagnetic valve, a second interface of the electromagnetic valve is connected with an air inlet of a vacuum pump, a third interface of the electromagnetic valve is communicated with an air outlet of the vacuum pump, and a fourth interface of the electromagnetic valve is communicated with the outside. The electromagnetic valve controls a first state in which the first pipeline is communicated with the second pipeline and the third pipeline is communicated with the outside, and controls a second state in which the first pipeline is communicated with the third pipeline and the second pipeline is communicated with the outside, and the first state can complete the vacuumizing process of the vacuum cavity; the vacuum pump pumps outside air out, the outside air flows into the vacuum cavity through the first pipeline, the air pressure value can be adjusted, liquid in the packaging bag is prevented from flowing into the vacuum cavity, meanwhile, residual liquid in the first pipeline can be blown into the vacuum cavity, and therefore liquid residues in the first pipeline are reduced, and pollution to objects in the using process is reduced.
