Description

Double layer cell formable layer is with to roller mould

Technical field

The utility model is related to the technical field of cellular board former, especially a kind of double layer cell formable layer two pairs of rollers Mold.

Background technology

Currently, cellular board is typically the honeycomb core two sides for being bonded in one layer thicker securely by two pieces of relatively thin panels And manufactured plank, also known as honeycomb sandwich construction.Because cellular board has many advantages, such as light, strong, steady, heat preservation, heat-insulated, shockproof, Therefore it is widely used in every field.PP cellular boards are one kind in numerous cellular boards, and annual output is very big.

However the keriotheca moulding process in existing PP cellular boards is all single one layer of PP fused raw material fitting in the market Negative pressure of vacuum is formed in the honeycomb hole roll surface of honeycomb roll, then by vacuumizing, by PP material plastics sucking mouldings at the PP honeycombs of single sheets Layer（Single hole PP keriothecas or diplopore PP keriothecas）, then in each compound one layer of PP in keriotheca top and bottom, form PP cellular boards.It should The moulding process of keriotheca is only one layer of PP layers of progress plastics sucking moulding, in order to which proof strength needs consumption PP material more, weight Measure it is heavier, PP material be drawn onto behind bottom since the stroke inhaled down is excessive, cause bottom surface PP material it is very few cause expect wall it is too thin, serious shadow Ring the intensity of keriotheca.By taking the honeycomb hole of 10mm height as an example, when raw material is drawn onto bottom, PP material in bottom surface are very thin, sternly Ghost image rings the performances such as resistance to compression and the warping resistance of later stage molding plank.

Invention content

The technical problems to be solved in the utility model is：In order to which solve in above-mentioned background technology of the existing technology asks Topic provides a kind of double layer cell formable layer with to roller mould, changes the molding structure of the keriotheca of PP cellular boards, to enhance PP The resistance to compression of keriotheca, warping resistance, shock resistance.

Technical solution adopted by the utility model to solve its technical problems is：Double layer cell formable layer with to roller mould, Including the upper honeycomb roll being distributed up and down and lower honeycomb roll, the roll surface of the roll surface of upper honeycomb roll and lower honeycomb roll is flowing through between the two Two layers of molten condition the effect of PP material under it is tangent, the PP of two layers molten condition expects respectively in the work of upper honeycomb roll and lower honeycomb roll There is two layers of PP keriotheca with lower honeycomb plastics sucking moulding, and two layers of PP keriotheca glues at upper honeycomb roll and lower honeycomb roll tangency location Knot is together.

Further specifically, in above-mentioned technical proposal, offered respectively on the upper honeycomb roll and lower honeycomb roll several The suction hole being connected with negative pressure of vacuum machine.

Further specifically, in above-mentioned technical proposal, the specification of the upper honeycomb roll is identical with the specification of lower honeycomb roll.

Further specifically, in above-mentioned technical proposal, the upper honeycomb roll and lower honeycomb roll are single hole honeycomb roll, or The upper honeycomb roll of person and lower honeycomb roll are double-hole honeycomb roller.

Further specifically, in above-mentioned technical proposal, the upper honeycomb roll and the mirror image setting up and down of lower honeycomb roll.

The utility model has the beneficial effects that：Double layer cell formable layer provided by the utility model is with to roller mould, with original The former come is compared, in the case of identical grammes per square metre, same cellular layer height, the formed in mould keriotheca intensity of the two pairs of rollers Higher；Compared with original former, such as to reach identical keriotheca intensity, this consumes more the PP material that roller mould needs It is few, so as to directly reduce cost.

Description of the drawings

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments described in the application, for those of ordinary skill in the art, before not making the creative labor It puts, other drawings may also be obtained based on these drawings.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the sectional view of Fig. 1.

In attached drawing marked as：1, upper honeycomb roll；2, lower honeycomb roll.

Specific implementation mode

The technical issues of in order to keep the utility model solved, technical solution and advantageous effect are more clearly understood, below In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific implementation described herein Example is only used to explain the utility model, is not used to limit the utility model.

See Fig. 1 and Fig. 2, the double layer cell formable layer of the utility model is with to roller mould, including the upper honeycomb that is distributed up and down The roll surface of roller 1 and lower honeycomb roll 2, the roll surface of upper honeycomb roll 1 and lower honeycomb roll 2 is flowing through two layers of molten condition between the two It is tangent under the effect of PP material, the PP material of two layers molten condition respectively under the action of upper honeycomb roll 1 and lower honeycomb roll 2 honeycomb plastic uptake at Type has two layers of PP keriotheca, and two layers of PP keriotheca is bonded together at upper honeycomb roll 1 and lower 2 tangency location of honeycomb roll.Its In, several suction holes being connected with negative pressure of vacuum machine are offered respectively on upper honeycomb roll 1 and lower honeycomb roll 2.Upper honeycomb roll 1 Specification is identical with the specification of lower honeycomb roll 2.Upper honeycomb roll 1 and lower honeycomb roll 2 are 1 He of single hole honeycomb roll or upper honeycomb roll Lower honeycomb roll 2 is double-hole honeycomb roller.Upper honeycomb roll 1 and the setting of about 2 mirror image of lower honeycomb roll.

Subtle adjustable gap is stayed between upper honeycomb roll 1 and lower honeycomb roll 2, such PP material are in roll surface by plastics sucking moulding It is bonded together at once in tangency location afterwards, then after cooling and demolding, the keriotheca of forming double-layer material structure, keriotheca at this time is It is docking together at image by the keriotheca of upper and lower two single holes or diplopore, support or the drawing mutually of upper layer and lower layer honeycomb It stretches, compares the PP keriothecas of single layer material, the keriotheca of this double-deck material structure can form better intensity, then compound upper and lower two After layer PP planks, the entire PP cellular boards intensity of formation can be promoted well.

Equally by taking the honeycomb layer height of 10mm as an example, the honeycomb roll for being about 5mm using two honeycomb height to roller mould, two Layer melting PP raw materials are fitted in honeycomb roll roll surface simultaneously respectively, and plastics sucking moulding is bonded in tangency location, and demoulding is molding at this time The molding PP keriothecas intensity of the more original former of PP keriotheca intensity compares the promotion for having matter.

It is above-described, the only preferable specific implementation mode of the utility model, but the scope of protection of the utility model is simultaneously It is not limited to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this reality It is subject to equivalent substitution or change with novel technical solution and its utility model design, should all covers the protection in the utility model Within the scope of.
