Description
Technical field
The utility model is related to packaging machinery field more particularly to a kind of leakage-proof environmental-protection valve bags.
Background technology
With the continuous development of present material science, novel material emerges one after another, and material property is also constantly changing,
Want preferably to preserve, transport, sell, the packing instructions of its product will also be improved therewith.Valve bag is as a kind of main
Packing appliance, carry important role in tasks such as the storages, transport, sale of material.As a kind of storage apparatus,
Require valve bag with certain to material protection effect, for the characteristic of a variety of materials, valve bag must have corresponding anti-
Each attribute such as light, moisture-proof, antistatic, to ensure that material never degenerates discoloration within certain time limit；It, will be straight as a kind of outer packing
It connects and is contacted with user, give the most intuitive impression of user, this requires valve bags to want durable, is conveniently operated, brief introduction U.S.
It sees.
However, due to valve bag be mainly used for pack edible powder, chemical powder, chemical fertilizer, synthetic material, explosive, grain,
The powderies such as salt, minerals or granular solid material, during packed and transported, can usually occur material from valve port leak out or
The case where ejection, causes loss of material or powder material to become damp and rotten, and causes to waste, cause damages to user.
Invention content
The utility model in view of the deficiencies of the prior art, provides a kind of leakage-proof environmental-protection valve bag, is connected using outside
The double-deck valve port layer structure can avoid the leakage of filling material completely, and effectively, applicability is wide for environmental protection.
The another object of the utility model is to provide the preparation method of above-mentioned leakage-proof environmental-protection valve bag.
The utility model is achieved by the following technical programs.
A kind of leakage-proof environmental-protection valve bag, including valve bag bag body and valve port, the bag body are cuboid, are set in the valve port
There are the first valve port layer and the second valve port layer with valve port coaxial line, the first valve port layer is sheathed in the second valve port layer, described
The outer wall of second valve port layer is bonded with the inner wall of the valve port；The first valve port layer is connected with the outside of the second valve port layer, institute
State the length of the first valve port layer, the length of the second valve port layer, the bag body width ratio be 6 ~ 8:13~16:10~11.
When the valve port sacked material, filling head is continued to stretch into the second valve port layer by the first valve port layer, material passes through
Second valve port layer inner port is fallen into valve bag；After the completion of charging, by material up push up in the way of valve port sealed；It is utilizing
When existing valve bag proceeds as described above, material has been possible to a little outside leakage, and when utilization the utility model valve bag
The case where material leaks out is can completely avoid, reason is：1. limiting the length of the first valve port layer：The width of the bag body
Than being 6 ~ 8:10 ~ 11, so that the inner port of the first valve port layer is located at the close bag intracoelomic cavity of the Delta Region formed on the upside of valve port
Side, when charging, avoid the first valve port layer from routing up outward；2. limiting the length of the second valve port layer：The width ratio of the bag body is 13
~16:10 ~ 11, gas and material in bag are blocked using the second valve port layer, prevents material from spraying；3. the length of the first valve port layer：The
The length ratio of two valve port layers is 6 ~ 8:13 ~ 16, the first valve port layer length of internal layer and the second valve port layer length of outer layer are according to one
Certainty ratio is arranged, and forms two valve port layers that inner port is misaligned, the second valve port layer is divided into the overlay region with the first valve port layer
The Non-overlapping Domain of domain and close bag intracoelomic cavity so that a little leakage enters overlay region in the material of Non-overlapping Domain after the completion of charging
In domain, and the external connections being connected with the second valve port layer by the first valve port layer block, and can effectively prevent the leakage of all materials
Go out, it is ensured that smooth filling, leakage-proof environmental-protection.
The first valve port layer and the second side of the valve port layer far from bag intracoelomic cavity are the first valve port layer and second outside it
Valve port layer can be that the outer end of the two is connected or the outer end of the first valve port layer is attached to the second valve port layer outer end and slightly leans on
Interior position.
Preferably, second valve port be placed on the bag body interior section length and the width ratio of the bag body it is not small
In 13:10.5；Under conditions of existing processing technology, if being less than this ratio, leakproof ash effect will be in a slight decrease.
Inventor by a large number of experiments find, it is preferred that the first valve port layer, the second valve port layer length ratio be 7:
15。
