Simple nitrogen filling packaging device

Abstract

The invention provides a simple and easy nitrogen-filled packing device and belongs to a food package technology. According to the technical scheme, a liquid nitrogen tank, a gas nitrogen tank, an air inlet cylinder one-way valve, an air cylinder, a piston, an air outlet cylinder one-way valve, a nitrogen supply control valve, a nitrogen supply nozzle, a nitrogen-filled food bottle and the like are sequentially connected and combined. The simple and easy nitrogen-filled packing device is characterized in that the air cylinder is provided with the air inlet cylinder one-way valve and the air outlet cylinder one-way valve; a piston centre shaft integrated with the piston is sequentially connected with a nitrogen supply connecting rod and a piston pedal through hinges; the valve handle of the nitrogen supply control valve is sequentially connected with a nitrogen supply switch valve rod and a nitrogen supply switch pedal through hinges; the nitrogen-filled food bottle is placed on the lifting table; a working table connecting rod and a working table pedal lever are sequentially connected below the lifting table; and the working table pedal lever, the nitrogen supply switch pedal and the piston pedal are integrally interlocked. The simple and easy nitrogen-filled packing device has the beneficial effects in that the simple and easy nitrogen-filled packing device with the advantages of less investment, no utilization of three-phase electricity, pedal power, low requirement on an operation technology, and less security accident can be realized; and the simple and easy nitrogen-filled packing device can be touched and seen, is popular to a family, a small workshop and an individual workshop, and is popular to food and vegetable vendors. The simple and easy nitrogen-filled packing device is a sensitive, convenient and effect tool.

Description

Technical field: [0001] The invention belongs to the technical field of food packaging, especially the technical field of a simple nitrogen-filled packaging device. Background technique: [0002] Looking at the existing technology of nitrogen-filled packaging, all of them use vacuum nitrogen-filled packaging, and most of them use mechanical power to achieve vacuuming and nitrogen-making nitrogen-filling sealed packaging. The equipment investment is at least more than 100,000 yuan, and three-phase electricity is required. It is a difficult task for a family or family workshop or a food and vegetable vendor. For this reason, a simple nitrogen-filling packaging device that does not require three-phase electricity and is powered by a pedal is welcomed by everyone. [0003] The prior art nitrogen-filled packaging, such as the patent name of the patent number ZL200610161603.5 called "vacuum nitrogen-filled packaging machine", is equipped with air compressors, vacuum pumps, nitrogen tanks...
