The utility model discloses the structure is ingenious, and the hot melt piece seals the back through ultrasonic wave hot melt and seals that the effect is good, effectively avoids sealing out the hourglass powder, because the base member piece is range upon range of with the hot melt piece setting, effectively promotes the load intensity of valve port moreover, avoids sealing the back valve port atress and breaks open.
Description
Technical Field
The utility model relates to a valve port bag field especially relates to an ultrasonic wave heat-seal valve port.
Background
With the continuous development of the material science at present, the new type of material comes out endlessly, and the material characteristics thereof are continuously changed, so that the packaging requirements of the product are improved along with the desire for better storage, transportation and sale. Valve bags are a major packaging material and play an important role in the storage, transportation, distribution, etc. of materials. As a storage appliance, the valve bag is required to have a certain protection effect on materials, and aiming at the characteristics of various materials, the valve bag has various properties such as light resistance, moisture resistance, static resistance and the like so as to ensure that the materials are not deteriorated and discolored within a certain period of time; as an outer package, will be in direct contact with the user, giving the user the most intuitive impression that the valve bag is strong and durable, easy to handle, simple and aesthetically pleasing.
However, since the valve bag is mainly used for packaging powdery or granular solid materials such as edible powder, chemical fertilizer, synthetic materials, explosives, grains, salt, minerals and the like, leakage or ejection of the materials from the valve opening often occurs in the packaging and transportation process and the filling process, so that material loss or damp deterioration of the powdery materials is caused, waste is caused, and loss is caused to users.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can effectively avoid sealing the ultrasonic heat-seal valve port of back hourglass powder.
Realize the utility model discloses the technical scheme of purpose is: an ultrasonic heat-sealing valve port comprises a base sheet and a hot melt sheet; the hot melt sheet is adhered to the base sheet, and the area of the hot melt sheet is the same as that of the base sheet; the two sides of the base sheet are connected and surround the cylindrical body with two open ends, and the hot melt sheet is positioned on the inner wall of the base sheet.
The base sheet is a liner paper layer.
The hot melt sheet is a PE film.
A bonding area is arranged on the outer wall of the base sheet; a peelable release layer is bonded to the bonding region.
The bonding area of the substrate sheet is pressure-sensitive adhesive; the stripping layer is release paper.
The bonding area of the base sheet is arranged around the outer wall of the base sheet in a circle.
A barrier plastic sheet is arranged in the inner cavity of the base sheet; the blocking plastic sheet is cylindrical, the front end of the blocking plastic sheet is connected with the hot melt sheet, and the rear end of the blocking plastic sheet extends towards the material filling direction; the diameter of the rear end of the blocking plastic sheet is smaller than that of the front end.
By adopting the technical scheme, the utility model discloses following beneficial effect has: the utility model discloses the structure is ingenious, and the hot melt piece seals the back through ultrasonic wave hot melt and seals that the effect is good, effectively avoids sealing out the hourglass powder, because the base member piece is range upon range of with the hot melt piece setting, effectively promotes the load intensity of valve port moreover, avoids sealing the back valve port atress and breaks open.
Drawings
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which
FIG. 1 is a schematic structural view of the present invention showing the removal of the bonding area;
FIG. 2 is a schematic structural view of the present invention;
fig. 3 is a sectional view of the present invention.
The reference numbers are: the base piece 1, the bonding area 1-1, the stripping layer 1-2, the hot melt piece 2 and the barrier plastic piece 3.
Detailed Description
Example one
Referring to fig. 1, the ultrasonic heat-sealing valve port of the present embodiment includes a base sheet 1 and a thermal melt sheet 2.
The hot melt sheet 2 is adhered to the base sheet 1, and the area of the hot melt sheet 2 is the same as that of the base sheet 1. The two sides of the base sheet 1 are connected and surround the cylindrical shape with two open ends, and the base sheet 1 is a lining paper layer on the inner wall of the base sheet 1 of the hot melt sheet 2, preferably, the lining paper layer is 80 g of paper. The hot melt sheet 2 is a PE film. And the base sheet 1 is pressed and ultrasonically heat-sealed through the ultrasonic hot press to seal the hot melt sheet 2 in a hot melt manner, so that the valve port is sealed.
Referring to fig. 2, the outer wall of the base sheet 1 is provided with a bonding region 1-1 connected with the valve port of the valve bag. The bonded area 1-1 is bonded with a peelable release layer 1-2. The stripping layer 1-2 is required to be stripped during installation, the valve port extends into the valve port part of the valve port bag, the bonding area 1-1 is bonded with the inner wall of the valve port part of the valve port bag to realize installation, the installation is very convenient, the adaptability is wide, and paper bags and woven bags can be installed. The adhesive area 1-1 of the base sheet 1 is a pressure sensitive adhesive. The stripping layer 1-2 is release paper. In order to avoid powder leakage of the valve bag, the bonding area 1-1 of the base sheet 1 is arranged around the outer wall of the base sheet 1 for one circle, so that the valve bag is bonded with the inner wall of the valve port of the valve bag for one circle.
Referring to fig. 3, a barrier plastic sheet 3 is arranged in the inner cavity of the base sheet 1. The two ends of the blocking plastic sheet 3 are open and are cylindrical, the circumferential surface of the front end is connected with the hot melt sheet 2, and the rear end extends towards the material filling direction. The diameter of the blocking plastic sheet 3 is gradually decreased from the front end to the rear end, so that leakage of materials from a valve port caused by air pressure during filling can be effectively reduced, and most of powder objects are blocked between the outer wall of the blocking plastic sheet 3 and the inner wall of the hot melt sheet 2 due to the fact that the diameter of the rear end of the blocking plastic sheet 3 is smaller than the diameter of the front end when the powder objects splashed outwards from the valve pocket are splashed outwards.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
