As a specific example, in the first embodiment and the second embodiment, the geometrical shaped body on geometry sheet material unit 32 104 uniformly from the downwardly projecting molding in sheet material top surface of geometry sheet material unit 32, the geometry of each geometric units branch The equal planform of body 104 is identical.As shown in Figure 4 b, when D2 arranges in a second direction, the geometric form of each geometry sheet material unit 32 Same direction (in the figure downwards) arrangement of the D2 in a second direction of shape body 104, the first sheet material unit of arbitrary neighborhood and second sheet material The alignment thereof of unit are as follows: so that the second geometric form of the first geometrical shaped body and the second sheet material unit on the first sheet material unit D2's shape body is staggered in a second direction, i.e. non-alignment state.As shown in Figure 4 b, axial pass-through holes 101 by a geometry inner hole 105 with The geometry spacer holes 106 of D2 alignment are put together in a second direction.At this point, the inner hole circumferential closure knot of the geometrical shaped body 104 Structure includes the geometrical shaped body 104 of the part of the sheet material flat wall and its two sides on adjacent geometry sheet material unit 32.Certainly, exist The shape and structure of each geometrical shaped body 104 of geometry sheet material unit 32 is identical and when being equidistantly spaced from, appropriate at this time mobile to adjust The whole aligned position along first direction D1 can also form suitable unit assembly 100.

In Figure 1b, it is clear that the axial pass-through holes 101 of part include a geometry inner hole 105, the axial pass-through holes of part 101 include three geometry inner holes 105.In Fig. 3, then each axial pass-through holes 101 include that a geometry inner hole 105 or one are several What spacer holes 106, and inner hole circumferential closure structure is flat sheets unit 31.

It is further to note that being passed through in unit assembly 100 of the invention along the axial direction that first direction D1 is sequentially distributed Through-hole 101 be not limited to include geometry inner hole 105 first kind axial pass-through holes 101, also may be present not includes geometry inner hole 105, And only include the second class axial pass-through holes 101 of geometry spacer holes 106, as shown in Figure 3.But it is at least wrapped in unit assembly 100 Include multiple first kind axial pass-through holes 101 being made of geometry inner hole 105 of a line or multirow.

In the first embodiment, unit assembly 100 and geometric units branch are strip, first direction D1 and Two direction D2 are vertical and two side length directions of respectively unit assembly 100, and second direction D2 is perpendicular to geometry sheet material unit 32 sheet surface, axial pass-through holes 101 are penetrated through along the thickness direction of unit assembly 100, i.e. the edge geometry inner hole centreline OO' The thickness direction of unit assembly 100.First direction D1 shown in Fig. 1 a is the length direction of unit assembly 100, second party It is the width direction of unit assembly 100 to D2, third direction D3 is the thickness direction of unit assembly 100, but all directions are fixed Position can be interchanged, and the invention is not limited thereto.And in first direction D1, second direction D2 and third direction D3 each other between any two It is also not necessarily limited to form right angle angle, such as third direction D3 and first direction D1 or second direction D2 can form acute angle, i.e., Geometry inner hole 105 is the angling hole relative to the core material cross section defined first direction D1 and second direction D2, rather than vertical hole.

In unit assembly 100, the adjoining boundary of adjacent geometric units branch can be by different several of two shape and structures What unit sheet 32 is spliced, that is, includes at least two kinds of geometry sheet material unit, constitutes the combination of profile sheeting unit Splicing.For example, the geometry inner hole 105 in the geometric units sheet material 32 of the first geometric units branch shown in Fig. 1 b is half positive six side The shape in shape hole, the geometry inner hole 105 in the geometric units sheet material 32 of the second geometric units branch are the shape of half diamond hole, also There is the geometry inner hole 105 in the geometric units sheet material 32 of third geometry branch for the shape of kidney slot, and three kinds of geometric units pieces Geometrical shaped body 104 in material 32 can be different along the span of first direction D1.

Due to unit assembly 100, adjacent Liang Ge geometric units branch all has different geometrical shaped bodies 104, i.e., extremely It include less two kinds of geometry sheet material unit 32, so that the geometry list of the adjoining in entire unit assembly 100 of the invention With a variety of axial pass-through holes 101 of different shapes along first direction D1 distribution between first branch.Such as it is shown in Fig. 1 b The second geometric units branch and third geometric units branch adjoining boundary multiple axial pass-through holes 101, axial pass-through holes 101 can be by the geometry spacer holes 106 of one and half kidney-shaped hole shapes and 105 structure of geometry inner hole of one and half regular hexagon hole shapes At, alternatively, axial pass-through holes 101 can by two or the geometry spacer holes 106 of several half kidney-shaped hole shapes with two or several The geometry inner hole 105 of a half regular hexagon hole shape is constituted.

It can be seen that different shape structure geometry sheet material unit constitute profile sheeting unit it is combined and spliced when, and Non- each geometry high point 102 and geometry low spot 103, which can correspond to, to connect, the geometry high point 102 or several of part What shape low spot 103 can be in hanging shape.

It should be noted that constitute above profile sheeting unit it is combined and spliced when, can also be other such as half water chestnuts Shape hole and half kidney slot are spliced into axial pass-through holes 101.In addition, the contact surface of the contact portion between geometry sheet material unit 32 is unlimited Connect in same type face, is also possible to such as plane and docking for cambered surface etc..In unit assembly 100, axial pass-through holes 101 shape is not limited to each shape shown in the drawings, is also possible to regular quadrangle, circle etc., not reinflated herein carefully to state.

It, only need to be along the when the shape and structure of two neighboring geometry sheet material unit 32 is identical in unit assembly 100 On the basis of Justified multiple geometry sheet material units 32 of one direction D1, geometry sheet material unit 32 is surrounded and is parallel to first The rotation axis (such as long side of geometry sheet material unit 32) of direction D1 is overturn, wherein so that two neighboring geometry sheet material unit 32 reverses direction on the contrary, on a geometry sheet material unit 32 geometrical shaped body 104 with it is another several after reverse flip D2 is aligned simultaneously integrally connected to geometrical shaped body 104 on what sheet material unit 32 in a second direction.Wherein, the geometry after reverse flip In sheet material unit 32, the location swap of spikes/low- points.Certainly, two neighboring geometry sheet material unit 32 can also be surrounded and is parallel to The rotation axis (such as long side of geometry sheet material unit 32) of first direction D1 is overturn and reverses direction is consistent, and then along first party It adjusts to D1 is mobile with the certain distance that is staggered, thus as previously mentioned, so that the first geometrical shaped body on the first sheet material unit It is successively alternately arranged with the second geometrical shaped body on the second adjacent sheet material unit along first direction D1.As a result, based on above-mentioned Any arrangement overturning rule, strictly can accordingly form entire unit assembly 100.

In addition, sheet material unit can be single sheet structure, it is also possible to multi-layer sheet structure.As shown in figure 5, geometry piece Material unit 32 includes tri- layers of A, B, C, and layers of material may be the same or different.When wherein the material of adjacent two layers is identical, it can be considered Same layer.When adjacent geometry sheet material unit 32 is combined into cell cube assembly 100, combination can be A-A-C-C The A layer of contact, i.e. the A layer of the geometry sheet material unit 32 geometry sheet material unit 32 adjacent with side combines, while geometry sheet material list The C layer of the C layer of the member 32 geometry sheet material unit 32 adjacent with the other side combines.It can certainly be such as A-C-A-C or A- The combination of A-C-C-A-C also can also be combination more than both aforesaid ways or both.When there are A- in combination When C is combined, a certain distance can be mutually staggered between geometry sheet material unit 32 neighbouring at this time and is then combined.

Optionally, flat sheets unit 31 and/or geometry sheet material unit 32 are for double layer sheet structure and including with compatible Property for realizing set-up function functional layer and be used for load bearing structure sheaf.Wherein, structure sheaf and functional layer are two The material of unlike material, but both materials have compatibility, i.e. and two kinds of materials can not be directly warm by binder in mold Composite molding.Further, the multilayer tablet that flat sheets unit 31 and/or geometry sheet material unit 32 are three layers or three layers or more Material structure and including for realizing set-up function functional layer and be used for load bearing structure sheaf.When adjacent materials at two layers it Between when not having compatibility, three layers or three layers or more of multi-layer sheet structure further includes the adjacent two layers for being folded in incompatibility In low temperature glue-line so that adjacent materials at two layers molding bonded.Alternatively, three layers or three layers or more of multi-layer sheet structure is also It may include the material of three kinds or more unlike material, the arbitrary neighborhood materials at two layers in this three kinds or more material is equal Has compatibility, i.e. arbitrary neighborhood materials at two layers can not pass through the directly hot composite molding of binder in mold.Certainly, this hair Bright without being limited thereto, three layers or three layers or more of multi-layer sheet structure can also be other materials combining form.For the load for improving core material The minimum thickness of the single sheet structure of lotus ability, flat sheets unit 31 and/or geometry sheet material unit 32 should be preferably arranged to Not less than 0.1mm.

The thermoplastic composition core material of the simple and novel honeycomb shape of composed structure is elaborated in conjunction with attached drawing above, passes through list A geometry sheet material unit 32 or flat sheets unit 31 are arranged with geometric units subcombinations, polymerization can form combination core material, Manufacture easy to process reduces cost, will also carefully state below.But the advantages of thermoplastic composition core material of the invention, is without being limited thereto, more Importantly, due to processing convenience set forth below, thermoplastic composition core material according to the present invention has larger wall Other reinforcing materials etc. can be filled in thickness, so that high intensity is realized, particularly suitable for heavily loaded field etc..

The thermoplasticity core material of existing round tube honeycomb or semiclosed folded-sheet honeycomb structure is required in forming process using plastic uptake Or blow molding process is inhaled since the molding of thermoplastic material is limited by various reasons such as material plastic property and tonnages Modeling or blow molding process should not be used to process planform complexity and the biggish product of wall thickness.Which limits the maximums of honeycomb hole Hole wall, and process flow is discontinuous, and processing efficiency is low, at high cost.In thickest by limited time, central filler material is easy to produce Raw broken wall forms rejected product to destroy the structure of core material.In an embodiment of the present invention, sheet material unit 32 is by smooth 10 compression moulding of sheet material, it is no blow molding or plastic uptake link, so that the technique in terms of without wall thickness limits.Referring to Fig. 1 b, passed through axially In through-hole 101, the axis hole peripheral wall of axial pass-through holes 101 is divided into contact portion wall thickness and non-contact portion wall thickness, in thermoplastic of the invention Property combination core material in, the minimum thickness of the axis hole peripheral wall of axial pass-through holes 101 should be not less than 0.1mm, and the maximum of axis hole peripheral wall is thick Degree is not only restricted to processing technology.The thickness of axis hole peripheral wall (such as can be increased by increasing briquetting pressure of the pressurization on sheet material 10 The pressure etc. of forming roller pair) or increase the realizations such as molding extrusion pressure of sheet material 10 and thicken.It can guarantee enough wall thickness thickness When, addible packing material type is more in sheet material 10, and sheet material is not allowed to be also easy to produce broken wall in process, mentions significantly High production efficiency and the diversified production range for having expanded product.

In addition, the external diameter of a circle of the axial pass-through holes 101 of arbitrary shape can be preferably arranged to be not less than 1mm；With/ Or, can be preferred by the hole axial length of the axial pass-through holes 101 of arbitrary shape and the diameter ratio of the circumscribed circle of the axial pass-through holes 101 It is set as no more than 200, so that core material obtains more preferably heavily loaded lightening effect.

Relative to the metal formings material such as traditional steel and aluminium, thermoplastic material have light weight, corrosion-resistant, good insulating, The advantages that easily bonding and weld.In addition, plastic plate is easy recycling, it is convenient for secondary operation, can economizes on resources.Currently, thermoplastic Property the positive component of material substitute traditional metal materials, can be used for the fields such as building, traffic, container.In the present invention, sheet material unit Material use thermoplastic material, and the metal formings material such as non-aluminum, iron, to realize itself lightweight, therefore sheet material unit Material may include thermoplastic polymer, the fibre-reinforced thermoplastic resin based composite material of thermoplastic polymer, filler filling And/or plastic deformation paper, steel plastic compount object etc..As an example, thermoplastic polymer can be polypropylene, polyethylene, gather Amide, thermoplastic polyester, polyvinyl chloride, polystyrene, polycarbonate, polyphenylene oxide, thermoplastic elastomer (TPE), multi-component copolymer thermoplasticity One of plastics, polymethyl methacrylate, polyphenylene sulfide, polyether-ether-ketone and polyimides or in which a variety of blends. In the thermoplastic polymer of filler filling, filler can be organic matter, inorganic matter or both to have, specifically, and filler can be with For wax, talcum powder, carbon black, white carbon black, kaolin, calcium carbonate, stearic acid, calcium stearate, whisker, titanium dioxide, iron oxide, face One of material, fire retardant and antioxidant or in which a variety of compositions.The fibre-reinforced thermoplastic resin-based composite wood Fiber in material can be one of organic fiber, inorfil, metallic fiber, macromolecular fibre, plant fiber or a variety of. Fiber in the fibre-reinforced thermoplastic resin based composite material can be glass fibre, carbon fiber, basalt fibre, steel One of silk fiber, polypropylene fibre, polyester fiber, ultra high molecular weight polyethylene fiber, polyimide fiber and flaxen fiber Or many of composition.

As shown in fig. 7, sheet material unit or the sheet material 10 for going out sheet material unit for machine-shaping can be single layer structure or more Layer structure, such as the sandwich sandwich of diagram, wherein may include central filler material layer, such as the B layer of diagram.Centre is filled out Filling material layer can be enhanced packing material and/or function packing material.It is strong that enhanced packing material can significantly increase core material Degree, can also fill function packing material, such as fire proofing and/or acoustic material, to realize the functions such as fire-retardant, sound insulation.This The thermoplastic composition core material of kind of the achievable relatively thick with packing material, can be applied to more demanding to high-strength light each In a field, such as in the increasing various carrier vehicles of load-carrying, especially heavily loaded electric power transporting coal train or cruising ability are not The electronic logistic car of car body need to be mitigated enough etc..

It is after molding shown in Fig. 1 a to obtain the satisfactory thermoplastic composition core material that can be realized lightweight heavy duty It, can be more as subtracting the axial pass-through holes 101 in matter hole to realize lightweight by being arranged in unit assembly 100.Referring to figure 1a, in times of unit assembly 100 defined with second direction D2 by first direction D1 and intersected with 100 entity of unit assembly One plane, i.e., in any cross sectional planes of unit assembly 100, plane voidage should be not less than 40%, further, plane Voidage should be not less than 60%.In the above-mentioned cross sectional planes of unit assembly 100, the plane voidage, that is, each axial direction The hole area of section summation of through hole 101 and the ratio between the site area of the cross sectional planes.

It is light-weighted simultaneously, for realize heavy duty, in addition to material select, should also improve material volume utilization rate, i.e., along carry Lotus Impact direction is able to bear the live part of load and the mass ratio of integral part or volume ratio.For popular, along load by The true part of the force in power direction is load bearing live part, and perpendicular to the material part or blank part of load Impact direction Dividing then is load bearing inactive portion, and the material volume utilization rate of inactive portion is 0.As an example, in fig 1 a, working as third Direction D3 is when bearing compressive load direction, and the material volume utilization rate of unit assembly 100 is not less than 60%, it is preferred that material Expect that volume utilization is not less than 80%.

It should be noted that since the adjacent Liang Ge geometric units branch of unit assembly 100 all has different geometry The structure of bodies 104, i.e., adjacent geometric units branch is different, and plane voidage and/or material volume utilization rate may Difference, so that can have a variety of different performances or branch's averag density etc. in same core material.

Wherein, the definition about material volume utilization rate has reality along loading direction when material bears compressive load Body material and the accumulative height of solid material are more than or equal to the material volume and material of the maximum height part of 95% direction material The ratio between total volume is material volume utilization rate.Since material is generally difficult to as regular shape, there are both ends defects, central defect Or other combined defects etc., in order to make it easy to understand, in combination with patented invention content, the case where will likely encountering herein point For five classes, first kind Quan Guantong, the second class is an existing defects, and third class is both ends existing defects, and the 4th class is centre Existing defects, the 5th class are combined.

Specifically, Fig. 6 a~Fig. 6 e ' respectively illustrates the calculation specifications of above-mentioned five classes situation, wherein compressive load direction It is Y-direction, Y₀For material maximum height, Y₁To have the height of solid material, Y₂For flaw height, material volume utilization rate It is S₁/S₀, S₀For universe area, S₁For effective area, S₀Calculation formula is S₀=∑ dxdy.For the significant surface of five class situations Product S₁Calculation specifications, will address one by one below.It should be noted that definition material volume utilization for simplicity, material bodies The definition of product utilization rate censures material volume using cross-sectional area, such as cross section in the Z-direction that does not mark in the example shown and existing There is diagram all the same, S can be used at this time₀Instead of material total volume, S₁Instead of material effective volume；Such as along Z-direction cross section with Existing diagram is not identical, then total volume is actual volume, and effective volume is then that any one cross section meets and defined above has Imitate the sum of the volume of entity of cross section.Also, in view of material is not when destroying, certain change can occur under load effect Shape, so that accumulative height slightly below maximum height can also bear load originally, but the deflection of material is limited, therefore is provided tired The maximum height of direction material of the meter height more than or equal to 95%, i.e. Y₁≥0.95Y₀, Y₂≤0.05Y₀。

When the structure of thermoplastic composition core material is full perforation, referring to Fig. 6 a, Fig. 6 a ', the dash area of Fig. 6 a is illustrated The total cross-section of bearing wall, the total cross-section area of the bearing wall are S₀；The bearing wall of support force can be contributed in loading direction Live part is the dash area of Fig. 6 a ', area S₁, S₁=S₀=∑ dxdy.When the structure of thermoplastic composition core material is one When head existing defects, referring to Fig. 6 b, Fig. 6 b ', the dash area of Fig. 6 b illustrates the total cross-section of bearing wall, the bearing wall it is total Cross-sectional area is S₀；The dash area that the live part of the bearing wall of support force is Fig. 6 b ', face can be contributed in loading direction Product is S₁, S₁=∑ dxdy ∣ Y₀≥y≥Y₁.When the structure of thermoplastic composition core material is both ends existing defects, referring to Fig. 6 c, figure The dash area of 6c ', Fig. 6 c illustrate the total cross-section of bearing wall, and the total cross-section area of the bearing wall is S₀；In load side The dash area for being Fig. 6 c ' to the live part for the bearing wall that can contribute support force, area S₁, S₁=∑ dxdy ∣ Y₀≥y ≥Y₁.When the structure of thermoplastic composition core material is central defect, referring to Fig. 6 d, Fig. 6 d ', the dash area of Fig. 6 d, which illustrates, to be held The total cross-section of wall is carried, the total cross-section area of the bearing wall is S₀；Having for the bearing wall of support force can be contributed in loading direction The dash area that effect part is Fig. 6 d ', area S₁, S₁=∑ dxdy ∣ Y₀≥y≥Y₀-Y₂.When the knot of thermoplastic composition core material When structure is combined defect, referring to Fig. 6 e, Fig. 6 e ', the dash area of Fig. 6 e illustrates the total cross-section of bearing wall, the bearing wall Total cross-section area be S₀；The dash area that the live part of the bearing wall of support force is Fig. 6 e ' can be contributed in loading direction, Its area is S₁, S₁=∑ dxdy ∣ Y₀≥y≥Y₁And Y₀≥y≥Y₀-Y₂。

For the thermoplastic composition core material for processing cellular first embodiment shown in Fig. 1 a, Fig. 1 b, shown in Fig. 7~Fig. 8 c Embodiment in, provide the first production method of thermoplastic composition core material.Unit shown in Fig. 1 a, Fig. 1 b is combined below For assembly 100, to illustrate the machine-shaping process of the unit assembly 100.

Referring to Fig. 7~Fig. 8 c, the production method of the thermoplastic composition core material includes the following steps that assembly line is worked continuously:

S181, the smooth sheet material 10 of multiple groups is persistently exported along assembly line outbound course X with packet mode, multiple groups sheet material 10 Sheet surface is parallel to each other and is spaced apart along the broadside outbound course Y of sheet material 10；

S182, grouping Processing each group sheet material 10, by every group of 10 division processing of sheet material at along assembly line outbound course X in band-like The multiple geometry sheet material units 32 extended are machined in the sheet surface of geometry sheet material unit 32 along assembly line outbound course X weight The non-closed geometrical shaped body 104 presented again；

S183, each geometry sheet material unit 32 after division processing in each group is overturn by preset angle with packet mode respectively Degree, so that the length direction L of the geometry sheet material unit 32 after overturning is kept along assembly line outbound course X, geometry sheet material unit 32 Width direction W and sheet material 10 broadside outbound course Y between formed angle a；

S184, each geometry sheet material unit 32 after overturning in each group is uniformly collapsed and is laminated along broadside outbound course Y It is spliced into unit assembly 100.

As it can be seen that the thermoplastic composition core material structure shape of aforementioned production method production is novel, at least by multiple geometric units Branch's splicing composition, and arbitrarily adjacent Liang Ge geometric units branch has different geometrical shaped bodies, each geometric units point Portion includes at least multiple geometry sheet material units 32, is substantially distinguished from the cellular-core of existing unicity structure.Spirit can be passed through It is living to convert different geometric units subcombinations to change the performance or branch's averag density etc. of different branches in same core material, from And make can have a variety of different performances or branch's averag density etc. in same core material, to be applied to that there is specific function demand Field, meet the diversified demand in practical application.In addition, this production method has ensured that the production of thermoplastic composition core material connects Continuous property, can automatic assembly line production, the sheet material 10 continuously exported by assembly line upstream end processes from assembly line downstream The unit assembly 100 persistently exported, compared to the artificial discontinuous production method participated in or interrupt is needed, production efficiency is obtained It is greatly improved, to have versatility large-scale production, the basis of product cost is greatly reduced greatly.Wherein, pass through the side such as roll-in Formula direct die mould on sheet material 10 goes out the wave crest and trough of honeycomb, i.e. geometrical shaped body 104 etc., the rings such as no plastic uptake or blow molding Section, so that sheet material can have biggish wall thickness, can be filled more reinforcing material, so that the unit assembly 100 after roll-forming There can also be biggish wall thickness, intensity is high, and wastes without any material, realizes economizing type production.

Comparably, there are mainly of two types for the existing thermoplastic resin-based honeycomb core largely used, and one is round tube bees Nest core, main technique are high speed double-layer coextrusion out compared with the single round tube of thick wall, and forming wall thickness through blow molding is 0.1~0.3mm thick More light wall pipes are superimposed as sticking together and are put into baking oven by light wall pipe, so that outer layer low temperature material melts and inner layer high temperature material holding solid-state, it is cold But it is cut as required after.Second is semiclosed folded-sheet honeycomb structure, and technical process is that continuous material passes through perpendicular to material face Plastic deformation generate, to form semi-hexagon shape cell-wall and lesser join domain, by being folded along transmission direction, unit It keeps away and meets, to form honeycomb body structure.It is limited to production technology, this two kinds of production methods can only all be produced with unicity knot The cellular-core of structure, the diversified demand being unable to satisfy in practical application.Also, the cellular simple process of the round tube of the first, But since production discontinuously causes, i.e., there is heating temperature-fall period in baking oven, cause round tube honeycomb production efficiency lower, production cost There is blow molding link in forming process, lead to that functional stuffing and reinforcing filler can not be filled in material in height, application is limited. The technique production of second of semiclosed folded-sheet honeycomb structure is continuous, but its it is semiclosed cause material waste more, exist in molding and inhale Link is moulded, causes also fill functional stuffing and reinforcing filler in material, application is limited.

And the present invention can be fully solved that honeycomb-shaped structure present in above two scheme is single, can not fill functional stuffing The problem of with reinforcing filler, Gao Chengben and material waste, provide it is a kind of it is novel combine a variety of honeycomb-shaped structures, it is fillable, Low cost, economizing type honeycomb combination core material and its production method and production equipment.

In the first production method of the invention, multiple groups flat sheets 10 can be exported by multiple groups along the broadside of sheet material 10 The outlet for the thermoplastic material molding equipment 1 that direction Y is spaced apart persistently exports, can be on horizontal pipelining platform along stream Waterline outbound course X persistently mobile output.Sheet material 10, the not same order of geometry sheet material unit 32 in process for ease of understanding The orientation of section and mutual position relation, in the embodiment of each production method shown in the drawings and production equipment, definition Absolute coordinate system and relative coordinate system.Wherein, sheet material 10 steadily exports, and can't overturn, therefore assembly line outbound course X, Broadside outbound course Y, that is, sheet material 10 length direction and width direction.Accordingly it is contemplated that being exported with the molding of sheet molding equipment Or the start position of pipelining platform defines absolute coordinate system.In each method and apparatus embodiment shown in the drawings, Absolute coordinate system includes assembly line outbound course X, broadside outbound course Y and flowing water line platform vertical direction Z, origin position setting In the molding outlet of sheet molding equipment or the start position of pipelining platform, assembly line outbound course X, broadside output side Limit the levelling bench surface of pipelining platform or the sheet material from the sheet material 10 for molding mouthful horizontal output jointly to Y Surface.Meanwhile dynamic coordinate system, i.e. width direction W (i.e. Fig. 1 a of geometry sheet material unit 32 are defined for geometry sheet material unit 32 In third direction D3) and length direction L (i.e. the first direction D1 of Fig. 1 a), geometry sheet material unit 32 can be showed clearly The positional relationship before and after steering in process.

As shown in figure 9, the production method of the present embodiment can outline include output step, division processing step, overturning step Splice step with collapsing.Wherein, in output step 181, multiple groups is persistently exported along assembly line outbound course X with packet mode and are put down Whole sheet material 10, the sheet surface of multiple groups sheet material 10 are parallel to each other and are spaced apart along the broadside outbound course Y of sheet material 10.Work as list When the size of first assembly 100 in a second direction requires larger, then greater number of geometry sheet material unit 32 is needed to be spliced, Thus sheet material 10 also correspondingly needs to increase along the size of broadside outbound course Y.However, when sheet material 10 is along broadside outbound course Y It is oversized when, the production difficulty of sheet material 10 greatly increases, and the production cost of output equipment and output mask and maintenance at This is also greatly increased.Also, due to the limitation of production technology and equipments, output broadside ruler of the sheet material 10 along broadside outbound course Y Very little also limited, the size for the unit assembly 100 for thus causing single group output sheet material 10 to be produced is restricted significantly.And Output step 181 of the invention combines multiple groups using the way of output along broadside outbound course Y grouping and multiple groups output sheet material 10 The broadside size of the broadside outbound course of sheet material 10 can greatly increase the geometry sheet material list along broadside outbound course Y synchronism output The quantity of member 32, has thus significantly expanded the production size of unit assembly 100.

In addition, the smooth sheet material 10 of multiple groups is persistently exported along assembly line outbound course X with packet mode, so that every pack Material 10 is subsequent can correspond to the geometric units for processing the thermoplastic composition core material of the first embodiment as shown in Fig. 1 a, Fig. 1 b Branch, the geometric units branch of the embodiment include multiple geometry sheet material units 32 with same geometry body 104.? The geometric units with different geometries body 104 are processed by the different geometrical shaped body molding assembly 2 of flexible transformation Branch, to change the performance or branch's averag density etc. of different branches in same core material, so that can have in same core material A variety of different performances or branch's averag density etc..In addition to the unit assembly 100 of first embodiment, naturally it is also possible to flexible group Close the unit assembly that various different structures are more formed by geometric units branch that different geometry sheet material units 32 forms 100, the invention is not limited thereto, and this makes it possible to obtain the various unit assemblys with different branch's performances or branch's averag density 100。

Optionally, output step 181 may include；

To be layered extrusion way output, so that sheet material 10 is formed as the multi-layer sheet structure along sheet thickness direction.

Wherein, it is squeezed out by layering and is directly compounded to form the sheet material 10 with multi-layer sheet structure, multilayer tablet in mould Material structure may include for realizing the functional layer of set-up function and for load bearing structure sheaf, and functional layer cocoa is fire-retardant Layer, erosion resistant coating or puigging, however, the present invention is not limited thereto also may be, for example, the function that gas defence layer etc. has other various functions Layer.Sheet material between layers can have compatibility, i.e. two kinds of materials can not be directly warm by binder in mold Composite molding；When sheet material between layers does not have compatibility, binder can be used to incompatible materials at two layers It is bonded.The different performance of multilayer material can be combined by the sheet material 10 of multi-layer sheet structure, to form a variety of function of collection The incomparable excellent properties of the material of single structure can be possessed in the functional structure material of one, can be applied to that there is difference The multiple fields of application scenarios.
