Abstract
The utility model discloses a molding central spindle of a liquid paper tank, which is characterized by comprising a main body the outer surface of which is coated with high temperature resistant material, and a fixed end integrally connected at the lower end of the main body, wherein the outer surface of the main body is provided with a concave air exhaust groove and a sealing surface used for sealing a side edge, an axial through hole is arranged in the main body, the air exhaust groove is provided with an air exhaust hole communicated with the axial through hole, and a cooling device is arranged in the main body. The utility model has the advantages that paper-plastic composite material with an aluminum foil layer can be rolled into a paper tube via the central spindle, then a top cover, a bottom cover and the paper tube are heated, pressurized and sealed to produce a liquid paper tank which can replace a ring-pull can via subsequent processing, which not only reduces the use and waste of metal resources but also reduces the production cost and the environment pollution, and the production and the processing are simple, convenient and quick; and the cooling device is arranged in the main body to make the central spindle keep constant temperature, so the melting of PE on the surface of the paper-plastic composite material caused by excess temperature of the central spindle is prevented.
Description
Technical field
The utility model relates to a kind of process equipment of liquid paper can, relates in particular to a kind of forming core shaft of liquid paper can.
Background technology
Traditional liquid beverage packs and substantially all adopts tinplate easy-to-draw jar, causes beverage rotten in the beverage to prevent that bacterium from entering, and prevents the ultraviolet ray irradiation and decompose vitamin in the beverage.But do the tank body and the bottom of pop can with tinplate, do easy-to-draw lid, can consume a large amount of iron and aluminium, and can bring certain environmental pollution with aluminium.
And in order to reduce using and wasting, reduce production costs and of metals resources to the pollution of environment, advocate the theory of current social environmental protection low-carbon (LC), the also available paper compound material that has an aluminium foil layer substitutes tinplate and makes the packing paper can, and this paper can play the intrusion that stops bacterium equally and prevent vitamin in the beverage to be subjected to ultraviolet the influence and the effect of decomposing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of forming core shaft of Working liquids paper can with the liquid paper can that reduces production costs that be used for.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of forming core shaft of liquid paper can, comprise that outer surface is coated with the stiff end that the main body that is coated with exotic material and one are connected described main body lower end, the outer surface of described main body is provided with the groove and be used for the face that seals that side seals of bleeding of indent, be provided with axially extending bore in the described main body, the described groove of bleeding is provided with the aspirating hole that is connected with described axially extending bore, is provided with cooling device in the described main body.
Described cooling device comprises two axial waterways that are arranged in the described main body, and the upper surface of described main body is provided with the tank that two waterways are connected.
Described tank be shaped as annular.
The described groove of bleeding is on the netted outer surface that is evenly distributed on described main body.
The material of described main body is 7075 extra super duralumin alloys, and described exotic material is a Teflon.
The outer surface of described stiff end is provided with plane of orientation.
Described main body is provided with demoulding tapering, after the paper web of forming paper can machines, makes things convenient for coming off of paper web.
Compared with prior art, the utility model has the advantages that by this mandrel and the paper compound material that has aluminium foil layer can be rolled into paper web, promptly made the liquid paper can that can replace pop can after through follow-up processing top cover, bottom and paper web being heated pressurizing and sealing then, promptly reduced using and wasting of metals resources, also reduce production costs and to the pollution of environment, and production and processing is simple, convenient, fast; And be provided with cooling device in the main body, and can make mandrel keep constant temperature, prevent that the mandrel temperature is too high and cause the thawing of composite paper-plastic material surface PE that in addition, the both sides of stiff end are provided with plane of orientation, the installing and fixing of aspect mandrel.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of forming core shaft of liquid paper can, comprising that outer surface is coated with is coated with Teflon and is provided with the main body 1 of demoulding tapering and the stiff end 2 that one is connected main body 1 lower end, the outer surface of stiff end 2 is provided with plane of orientation 21, the outer surface of main body 1 is provided with the netted equally distributed groove 3 and be used for the face that seals 11 that side seals of bleeding of being of indent, be provided with axially extending bore 4 in the main body 1, the groove 3 of bleeding is provided with the aspirating hole 31 that is connected with axially extending bore 4, be provided with two axial waterways 5 in the main body 1, the upper surface of main body 1 is provided with the annular water tank 6 that two waterways 5 are connected.
The operation principle of this device is: add man-hour, earlier the paper compound material is wound on the main body 1, the air that to bleed in the groove 3 by aspirating hole 31 are extracted out then, make the paper compound material and bleed between the groove 3 and form vacuum state and tightly be adsorbed on main body 1 surface so that involution, simultaneously, feeding cooling water in a waterway 5 flows out from another one waterway 5 through annular water tank 6, make it form a closed circuit, make it to keep constant temperature with the cooling mandrel, prevent that the mandrel temperature is too high and cause the thawing of composite paper-plastic material surface PE, the paper web involution that will be wound into by the paper compound material on the face of sealing 11 and cutting is blown into air at last the paper web that processes is come off from main body 1 in aspirating hole 31 then.
In the foregoing description, the material of main body 1 adopts 7075 extra super duralumin alloys.
