Simple and easy vacuum packaging device

Abstract

The invention provides a simple and easy vacuum packaging device in a food packaging technology. The simple and easy vacuum packaging device consists of a plastic food thin film bag, an electric heat sealing machine, bag opening upper-lower pressing soft belts, an exhaust pipe, an exhaust piston, a cylinder sleeve, an exhaust check valve, an air bleeding one-way valve, a pressure spring, a leverage pedal and the like; after the bag opening upper-lower pressing soft belts tightly press the exhaust pipe and the bag opening of the plastic food thin film bag, when the leverage pedal is stepped down by feet, the pressure spring is compressed, air exhaust is realized through a piston, the exhaust check valve is opened by air flow, and the air bleeding one-way valve is closed by the air flow, so that the air exhaust of the plastic food thin film bag can be realized; when the feet upward release the leverage pedal, the pressure spring expands, the piston is compressed upward, the exhaust check valve is closed by the air flow, and the air bleeding one-way valve is opened by the air flow, so that a preparation period of the next air exhaust of the plastic food thin film bag can be realized. In recirculation, the high vacuum inside the plastic food thin film bag is completed by pedal type vacuumization; and the opening is sealed by using the electric heat sealing machine, so that the simple and easy vacuum package of bagged particle foods can be realized through pedal power without spending a lot of money and using three-phase current. The simple and easy vacuum packaging device is a necessary tool for the family, particularly a self-employment venture in a family workshop, a food market or a tea market.

Description

Technical field: [0001] The invention belongs to the technical field of food packaging, in particular to the technical field of simple vacuum packaging devices. Background technique: [0002] Looking at more than 300 patents for vacuum packaging, most of the vacuum packaging in the prior art uses mechanical power to achieve vacuum pumping for sealing and packaging. A vacuum sealing machine invests tens of thousands of yuan and installs three-phase electricity. For family workshops, it is a difficult task. For this reason, it is everyone's hope to set up a simple vacuum packaging device that does not need three-phase electricity and is powered by pedals. [0003] The vacuum packing of prior art is that the patent name of CN87207100U is household vacuum packing box as the patent application number, but it is made up of air flow exchanging valve and electric heat sealing control electrical appliance etc. Its vacuum method is to squeeze the air bag by hand to extract the air in...

Problems solved by technology

However, it uses a power system to drive the elastic airbag respirator to complete vacuum pumping, and the structure is too complicated

[0005] The patent name of the existing technology such as the patent No. ZL87207157 is a household manual vacuum packer, but it realizes vacuum by manually reciprocatingly pulling the large and small pistons, which seems too complicated and laborious

[0006] The prior art such as th
