A kind of vacuum packing device
Technical field
The present invention relates to article packing equipment, specifically be meant a kind of vacuum packing device, it can be widely used on the article vacuum packaging equipments such as tealeaves, coffee.
Background technology
Some article such as daily tealeaves, coffee on the market, great majority adopt vacuum packaging bags packing back to sell, and have dwindled the volume of article like this, have made things convenient for it to carry, sell and prolonged the use shelf-life of article.
With the tealeaves vacuum packaging is example, and the vacuum-packed process of tealeaves was mainly for four steps: the tealeaves weighing, pack, vacuumize and seal.To vacuumize, to seal, existing great majority adopt outer odd test to vacuumize packing, are put in the vacuum packaging bag that tealeaves is housed on the operating table surface; The vacuum packaging bag sack is matched with the bleeding point of extraction equipment; Start extraction equipment then it is bled to vacuum packaging bag, be extracted into to a certain degree, sack is sealed; Take out vacuum packaging bag, both accomplished the process that it is vacuumized and seals.
The outer odd test of above-mentioned employing vacuumizes packaging process, and is only simple to the gas pumping in the vacuum packaging bag, needs good cooperation between sack and the bleeding point, just can bleed its complicated operation and use duration then; When sealing, a spot of gas is prone to get in the packaging bag from sack, makes degree of vacuum not high.
Summary of the invention
The present invention provides a kind of vacuum packing device, and its purpose is to overcome existing outer odd test and vacuumizes the manner of packing existence and vacuumize and use duration, the not high shortcoming of degree of vacuum.
In order to address the above problem, the present invention adopts following technical scheme:
