Description

The foaming rotor body structure

Technical field

The utility model relates generally to a kind of foaming rotor body structure, refers to a kind of polypropylene expanded cup body structure that forms with the paper cup molding manufacturing especially.

Background technology

At present, the foaming rotor body structure that utilizes single foamed material to make, its manufacture all adopts foaming-formed haply, as tw Taiwan patent announcement number: M330272 " but foamed plastic container of microwave " and M302322 " goblet ", this class formation is owing to adopt the factor of expanded material, all only can carry out for a long time in foaming-formed mode, this mode of production is also for adopting the unique feasible manufacture method of expanded material, in view of the above, it produces outfit can only be special special-purpose, can't be suitable for the manufacturing of the container of other non-foam material more at all.

The dealer is arranged then in order to distinguish to some extent with the foaming-formed foaming rotor body structure of above-mentioned tradition, the spy is with this glass body and the cup end, after the first moulding separately, foam the again bottom applying operation of cup, as tw Taiwan patent announcement number: M286203 " container ", its claim independent entry is: a kind of container, comprise: a hollow body, has a peristome from the outside coiling of top periphery, and one from the bottom first joint portion of bending extension upwards, and a connecting support, have the sealing of this hollow body of sealing, and one bend downwards from sealing portion periphery and to extend and can be in conjunction with second joint portion of this first joint portion.Wherein dependent claims is set: this container, and for low-density polymeric resin material system is selected from group that the resin material that comprises highly foamed polystyrene and polypropylene forms wherein.

In the above-mentioned technical characterictic, first joint portion that this is rounded and second joint portion such as desire obtain absolute adaptation, must just can reach the purpose of binding in the mode of heating roll extrusion, in view of the above, cooperate this case in the prior art of its patent specification, to mention again, known containers is material with the cardboard, must pass through gluing during manufacturing, the processing of pressing and other correspondence is handled or the like, consult this case accompanying drawing simultaneously: the cup body is shown as jointless structure, its aforementioned so-called gluing as can be known, pressing, be meant that known dixie cup body engages the overlapping place, but not the binding at the bottom of dixie cup body and the dixie cup; Hence one can see that, the hollow body of this above-mentioned known " container ", adopt the integrated mode of high expanded polypropylene made, it produces the production procedure that equipment needed thereby not only will be purchased whole foaming, more need the hot pressing binding facility of traditional dixie cup bottom to cooperate, high shortcoming of producing the facility cost is arranged on the contrary, and the limited wait improvements of container production material.

Moreover, tradition is the made various container of material with the cardboard, because the ductility of cardboard itself is not good, therefore in its bonding place that overlaps everywhere, though after overheated pressurization operation, this is subjected to the cal(l)iper of pressurization place, and any variation is not arranged, cause aforementioned pressurization place layer upon layer of more apparent lofty, the shortcoming that can't improve is fully arranged.

In view of this, the utility model still only can adopt unique foaming-formed method for making based on the many years of experience and the current production devices of producing the paper container at above-mentioned foam material, improves innovation.

The utility model content

Main purpose of the present utility model provides a kind of foaming rotor body structure that can effectively reduce manufacturing cost.

Another purpose of the present utility model provides a kind of foaming rotor body structure, and its plate body thickness in each junction of cup can be less than any plate body thickness that is pressurizeed.

For achieving the above object, the utility model provides a kind of foaming rotor body structure, and it comprises:

Foaming rotor body, upper end are provided with outside coiling cup lip, and the bottom is provided with the junction surface, the end that bends inwards; At the bottom of the foaming rotor, its periphery can turn up downwards and circularize the joint portion, for binding with junction surface, the end roll extrusion of foaming rotor body;

Wherein, this foaming rotor body is provided with the jointing edge of overlapping bonding in side, with circle around constituting tubular, this jointing edge, junction surface, the aforementioned end, and the foaming rotor body position of fitting for annular joint portion relatively, again after pressing, the thickness that its thickness is pressurizeed less than the foaming rotor body; And should the annular joint portion after pressurization is incorporated into junction surface, the end, the thickness that its thickness is pressurizeed at the bottom of less than foaming rotor.

Wherein, be that identical foaming plate is made at the bottom of this foaming rotor body and the foaming rotor, and this foaming plate, can be a kind of polypropylene expanded plate body or foamed polystyrene board body or IXPE foaming plate body wherein any.

As can be seen from the above technical solutions, foaming rotor body structure of the present utility model, can use fully with cardboard and produce the manufacturing machine of dixie cup and identical manufacturing process, produce foaming cup with the dixie cup structure, the cup of two kinds of unlike materials can be produced to reach, and manufacturing cost can be effectively reduced with the cover production equipment.

Foaming rotor body structure of the present utility model with the hot pressing mode combination, makes the plate body thickness at this place not show lofty less than any plate body thickness that is pressurizeed in each junction of cup.
