Description

Oil locking structure of food packaging bag

Technical Field

The invention relates to the technical field of food processing, in particular to an oil locking structure of a food packaging bag.

Background

The spicy stick is a food made of wheat flour or other grains and beans serving as main raw materials, is a snack, has good taste, is popular with consumers, even is exported to foreign countries in large batch, contains a large amount of food additives, has no unified manufacturing standard, is generally produced according to landmarks by spicy stick manufacturers on the market, and has the execution standards of DB41/T515-2007 and GB2760 generally, and the human health cannot be influenced as long as the spicy stick is added according to the national standards; the prior spicy strip packaging bag has two forms, the first is the most traditional bag sealing, the bag contains partial air, so that the bag body is bulged, but on the premise of long-term preservation, the fresh-keeping oil in the bag is positioned at the bottom due to the action of gravity for a long time and is disjointed with the spicy strips in the bag, so that the spicy strips are dried with less oil, and the eating taste is seriously influenced, the second is that the bag body is pumped into a vacuum state, so that the shelf life can be prolonged, the fresh-keeping oil can be locked in a fixed space, the condition of drying with less oil of the spicy strips is reduced, but the spicy strips are locked in position, and are compressed for a long time, so that the spicy strips are hardened and not fluffy enough, the influence on the taste is large, and in order to avoid the two conditions, the factory invests funds to research the new structure of the packaging bag, and provides an oil locking structure of the food packaging bag.

Disclosure of Invention

The invention mainly aims to provide an oil locking structure of a food packaging bag, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the invention adopts the technical scheme that:

the utility model provides a food package bag lock oily structure, includes outer bag and inner bag, the inner bag is located the inside of outer bag, and first half both bond together, be provided with pocket thin gasbag between the bottom of inner bag and the outer bag, pocket thin gasbag inboard is provided with the draw-in groove and supplies the inner bag bottom to insert to both bond, the outside of outer bag and pocket thin gasbag bonds mutually, the middle part of pocket thin gasbag is through the outside formula gas bag that resets of short trachea, but the formula gas bag that resets is gradually deformed after being extrudeed and is reset to the state of blowing, one side of the interior erroneous tendency formula gas bag that resets of short trachea is provided with the support, be provided with a plurality of groups of openings on the support, the support has the shutoff plectrum through spring coupling, the shutoff plectrum is located the shutoff inslot, the avris position in shutoff groove is provided with the backward flow passageway, the backward flow passageway includes import, ball, oblique raceway, hydraulic oil bag, pressure face, oil seal and export, the ball is located oblique raceway, the hydraulic oil seal is located the one end of oblique raceway.

Preferably, the hardness and the thickness of the outer bag material are both higher than those of the inner bag, and the inner bag is clamped inwards when the patch bag thin air bag swells.

Preferably, the spicy strips are arranged in the inner bag, and a fresh-keeping oil layer is arranged at the bottom of the inner bag.

Preferably, the formula that resets gas bag is the rubber material, is by manual extrusion, and later can be deformed gradually and reset to the state of blowing.

Preferably, the plugging groove is formed into a groove and matched with the plugging shifting piece in size, and the plugging shifting piece can move towards the pocket pasting thin air bag under the action of air pressure and then reset.

Preferably, one end of the inclined roller path is provided with a stop block acting on the ball, and the pressure surface is positioned on the hydraulic oil bag.

Preferably, under the contact of the ball, the pressure surface is sunken, hydraulic oil in the hydraulic oil bag is injected into the oil seal strip upwards, and the lower end surface of the oil seal strip is supported, so that the flow area of the return channel is reduced.

The invention provides an oil locking structure of a food packaging bag through improvement, and compared with the prior art, the oil locking structure has the following remarkable improvements and advantages:

(1) Design the thin gasbag of pocket, through the extrusion formula gas package that resets, gas gushes into the thin gasbag of pocket through the check valve in the twinkling of an eye, makes the gasbag swell, and inwards forms the clamping state to the inner bag when the thin gasbag of pocket swells, makes the fresh-keeping oil that is located the bottom upwards splash, abundant and peppery strip contact to guarantee edible taste, it is available at any time, can operate repeatedly, also can not produce the compression to peppery strip, effectively solve the problem of mentioning in the background art.

(2) The extrusion formula gas bag that resets can be with the help of self material attribute, can reset, the gaseous backward flow in return channel department gasbag, it makes the ball roll to the hydraulic pressure oil pocket direction of oblique raceway one end to produce the effort, form the extrusion to hydraulic pressure oil pocket, inject the inside hydraulic oil into the oil blanket strip in, the oil blanket strip props up downwards, make return channel's flow area diminish, thereby reach the purpose of control gas reflux speed, so, the time that the gas in the gasbag exists increases, the time of fresh-keeping oil and peppery strip effect also lengthens.

(3) Whole wrapping bag structural design is simple, and the material is cheap easily to be obtained, can not additionally increase too much cost to accord with actual service standard, improve work efficiency, the effect of using is better for traditional mode.
