Description

A kind of corrugated board

Technical field

The utility model is related to cardboard, more particularly to a kind of corrugated board.

Background technology

Corrugated board is an adherend for multilayer, and it is at least made up of one layer of waveform refill layer and a layer paperboard.Corrugation Cardboard has mechanical strength very high, can support and fallen by the collision and falling in goods handling process, mainly for the manufacture of carton, carton Sandwich and delicate articles external packing.Corrugated board temperature influence is small, and shading performance is good, typically by humidity influenceed also compared with It is small, but should not for a long time be used in the larger environment of humidity.

The patent of Publication No. CN203046409U discloses a kind of waterproof and dampproof corrugated board, including upper surface layer, in Interbed, undersurface layer, it is characterised in that：The upper surface layer is facial tissue, and the lower surface is base stock, and the intermediate layer is hole Paper, new paper, pit pass sequentially through glue and are bonded from top to bottom, and moistureproof oxidant layer is additionally provided with described facial tissue, base stock.

When this corrugated board makes, in order that the connection for obtaining corrugated board is more reliable, it is relative in any two-layer Glue is filled on face, is so needed using substantial amounts of glue.

Utility model content

The purpose of this utility model is to provide a kind of corrugated board, can save the usage amount of glue.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of corrugated board, bag At least two-layer plate body is included, plate body described in adjacent two layers is correspondingly arranged raised and draw-in groove, plate body described in adjacent two layers is also corresponded to and set It is equipped with groove and connector, adjacent two layers plate body raised and draw-in groove clamping engagement when abutting, when adjacent two layers plate body is abutted The connector is inserted in the groove and the outer wall of connector is spaced to form space with the inwall of groove, is filled in the space There is glue.

This programme ensures the bonding strength of adjacent plate body so as to ensure monoblock corrugation by way of clamping and bonding are combined The bonding strength of cardboard, and used due to this programme is the mode of many spot gluings, it is relative Nian Jie with existing face, greatly save The consumption of glue, although less, but because the yield of corrugated board is big, it adds up one piece of glue usage amount of corrugated board The glue quantity of consumption is big, therefore can greatly save cost.

Further, the connector face relative with groove side is in wavy.

The bond area of glue can so be increased, further the reliability of lifting adjacent plate body connection.

Further, the connector face relative with groove bottom land is in the arc-shaped of evagination.

The arc-shaped of evagination can play guide effect, while also further increasing the bond area of glue, be lifted adjacent The reliability of plate body connection.

Further, a pair of matching raised, draw-in grooves and a pair of grooves of matching, connector are spaced setting of staggering.

Staggering projection, draw-in groove and groove, the connector of setting can be so that each region bonding strength of adjacent plate body compares Uniformly, so cause adjacent plate body integrated connection reliability.

Further, two pairs of projections and draw-in groove are set per adjacent two Duis between connector and groove.

By the more of the quantity setting of raised draw-in groove, the consumption of glue can be further reduced.

Further, the raised outer ring being connected with inner ring including inner ring, by connection strap, be filled in inner ring and outer ring Between sponge.

So sponge is set between inner ring and outer ring, the deformability of projection can be increased, so as to raised and draw-in groove card Tighter, and sponge low cost.

Further, two pairs of projections of arbitrary neighborhood, draw-in groove or adjacent pair projection, draw-in groove and a pair of grooves, connectors Or spacing between arbitrary neighborhood two pair of a groove, connector is equal.

So equidistantly the projection of arrangement, draw-in groove and groove, connector cause tie point（Adhesive spots and card contact）Distribution Uniformly so that corrugated board integrated connection is reliable.

Further, the spacing is 25-30mm.

The bonding strength of the setting influence corrugated board of spacing, spacing is bigger, and bonding strength is poorer, but its cost is got over Low, above-mentioned spacing is set to 25-30mm by considering cost and bonding strength factor.

Further, the plate body sets three layers, and marine glue is coated with outside outermost plate body.

The setting of marine glue can cause that corrugated board has certain waterproof ability.

Further, the glue is polyvinyl alcohol environmental protection glue.

Polyvinyl alcohol environmental protection glue is pollution-free to production and use environment, and low cost, process is simple, adhesive effect are good, dry Solidification speed is fast, without hot pressing energy-saving effect remarkable advantage.

In sum, the utility model has the advantages that：The utility model simple structure, bonding strength is high, has Effect reduces glue quantity, cost-effective, environment friendly and pollution-free.

Specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

This specific embodiment is only that, to explanation of the present utility model, it is not to limitation of the present utility model, ability Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but As long as all being protected by Patent Law in right of the present utility model.

A kind of corrugated board, such as Fig. 1-2, including three ply board body 1, plate body 1 described in adjacent two layers are correspondingly arranged raised 2 Hes Draw-in groove 3, plate body 1 described in adjacent two layers is also correspondingly arranged fluted 4 and connector 5, raised 2 Hes when adjacent two layers plate body 1 is abutted Draw-in groove 3 is engaged by clamping, when adjacent two layers plate body 1 is abutted the connector 5 insert in the groove 4 and the outer wall of connector 5 with The inwall of groove 4 is spaced to form space 6, and glue is filled with the space 6, and glue is polyvinyl alcohol environmental protection glue.

Such as Fig. 2, the inner chamber that its further groove 4 is formed is cylindrical, the face relative with the side of groove 4 of connector 5 be in it is wavy, The face relative with the bottom land of groove 4 of connector 5 is in the arc-shaped of evagination.The bond area of glue can be increased by above-mentioned design, The reliability of the lifting connection of adjacent plate body 1.

Such as Fig. 1, in being cylindric, raised 2 cylindrical and raised 2 diameters are slightly larger than draw-in groove 3 for the inner chamber that draw-in groove 3 is formed Internal diameter；Such as Fig. 3, the outer ring 52 that raised 2 include inner ring 51, is connected by connection strap 53 with inner ring 51, be filled in inner ring 51 and Sponge 54 between outer ring 52, causes that raised 2 is tightr with the cooperation of draw-in groove 3 through the above way.

Such as Fig. 1, per two pairs of projections 2 and draw-in groove 3 is set between adjacent two pairs of connectors 5 and groove 4, arbitrary neighborhood two is to convex The spacing risen between 2, draw-in groove 3 or adjacent pair projection 2, draw-in groove 3 and groove 4, connector 5 is equal, and the spacing is 25- 30mm。

To cause that corrugated board has certain water resistance, such as Fig. 1, marine glue is coated with the plate body 1 of the superiors 7, general corrugated paper only has one side outside, therefore only need to coat one layer of marine glue 7 in the plate body 1 of the superiors.

When making, filling part glue in present groove 4 afterwards again presses two adjacent block bodies.
