Automatic packaging unit for vacuum packaging of inner bag and outer bag

Abstract

The invention relates to an automatic packaging unit for vacuum packaging of an inner bag and an outer bag, comprising a material hopper arranged on top of a case, a feeding device, a metering device, an inner bag loading device, an outer bag loading device and a vacuum sealing device arranged successively below the material hopper, the unit also comprises an inner bag film supplying device and an inner bag making device, and an outer bag conveying device which is arranged between the outer bag loading device and the vacuum sealing device; and an outer bag deposited device and an outer bag gaping device which are correspondingly arranged on the outer bag conveying device. The inner bag loading device includes a load hopper movably arranged below the metering device and an inner bag film clamping mechanism arranged at the lower end of the load hopper; the inner film supplying device includes a reel and an inner bag supporting mechanism; the inner bag supporting mechanism includes a hollow outer cylinder fixed in the case and a suspension type inner cylinder movably sleeved in the outer cylinder, and over-film gap is arranged between the inner and the outer cylinders. The unit organically connects each automatic steps of vacuum packaging of the inner bag and outer bag, automatically and continuously finishes the inner bag and outer bag vacuum packaging of fluid solid small grain materials such as tea and so on, and greatly improves automation degree and production efficiency.

Description

technical field

[0001] The present invention relates to a kind of equipment that is used for packaging materials such as tea leaves and other liquid solid particles, especially an automatic vacuum packaging machine used for vacuum packaging small liquid solid particles such as tea leaves in inner and outer bags, which can continuously and automatically complete the inner and outer bags. An all-in-one machine for vacuum packaging. Background technique

[0002] In order to prolong the shelf life and preservation period of liquid solid small particle materials such as tea, facilitate storage and better adapt to the needs and use of consumers at different levels, the materials are usually vacuum-packed. The existing vacuum packaging method of the inner and outer bags is to firstly put the predetermined amount of material after manual or automatic metering into the empty film inner bag, then fold the film inner bag approximately in the center, and then manually pack the folded in...
