Detailed Description
The invention is described in detail below with reference to the figures and examples.
The composite corrugated board comprises a surface paper layer 1, a corrugated core layer 2 and an inner paper layer 3, wherein the inner paper layer 3 is positioned on the inner side of the corrugated core layer 2, the surface paper layer 1 is positioned on the outer side of the corrugated core layer 2, the corrugated core layer 2 comprises a plurality of supporting paper blocks 4 which are glued between the inner paper layer 3 and the surface paper layer 1, a supplementing channel 5 is formed in the area between the supporting paper blocks 4, and the supplementing channel 5 is latticed between the surface paper layer 1 and the inner paper layer 3. The replenishment path 5 is provided with slidable replenishment paper blocks 6, and the replenishment paper blocks 6 fill the areas between the support paper blocks 4.
The middle part of the supplementary paper block 6 protrudes to form a butting end 7, the butting end 7 is butted between the inner paper layer 3 and the surface paper layer 1, and the supplementary paper block 6 is formed by winding paper sheets and is internally filled with foam particles 8. The end part of the supplementary paper block 6 contacting the adjacent supplementary paper block 6 is provided with an arc-shaped crimping end 9, and the part of the crimping end 9 contacting the adjacent supplementary paper block 6 is provided with a smooth crimping surface 10. One end of the paper supporting block 4 extends towards the inside of the replenishing channel 5 to form a leading end 11, the side surface of the leading end 11 is bent inwards or curved to form an arc shape, and the bent or curved end part supports the inner wall of the paper supporting block 4 to abut against the inner wall of the paper supporting block 4 in the area inside the paper supporting block 4. The side surface of the bent part of the leading end 11 is contacted with the side surface of the abutting end 7, and the distance between the adjacent leading ends 11 is less than the minimum width of the maximum section of the supplementary paper block 6. The shortest distance size between the abutting supporting paper blocks 4 is smaller than the maximum width size of the replenishing paper block 6, and the minimum width size of the replenishing channel 5 is larger than the maximum width size of the replenishing paper block 6.
In other cases, as shown in fig. 3, the supporting paper block 4 comprises two hollow circular truncated cone blocks with their reduced ends abutting against each other, and is formed by a plurality of paper strips which are twisted and then surrounded in a ring shape. More specifically, the supporting paper block 4 is formed by twisting a plurality of paper strips into a flat strip shape and then enclosing the flat strip shape into a hollow round table shape. One end of the hollow circular table block, which is far away from the reduced end of the hollow circular table block, is fixed with the inner paper layer 3 or the surface paper layer 1 through gluing, and the supporting paper block 4 is approximately shaped like a funnel. The adjacent and contacted reduction ends are glued with a shielding piece 12 for shielding the inner cavity of the hollow circular table block. The shielding piece 12 can increase the contact area between two hollow circular truncated cone blocks when the abutting hollow circular truncated cone blocks are not coaxial.
The implementation principle of the embodiment is as follows: the supporting paper block 4 plays a supporting role between the surface paper layer 1 and the inner paper layer 3, so that the composite corrugated board has preliminary structural strength, and simultaneously forms a supplementary channel 5 with the surface paper layer 1 and the inner paper layer 3. The twisted supporting paper blocks 4 have higher strength, and if the composite corrugated board collapses under external force, the reduced ends of the adjacent supporting paper blocks 4 are abutted and can be flattened by the external force, and the reduced ends of the supporting paper blocks 4 collapse inwards at the same time, so that the complementary channel 5 cannot be interfered or blocked due to bending.
The supplementary paper block 6 slides in the supplementary channel 5 and plays a role of filling, and if the flat strip-shaped supporting paper block 4 formed by rolling is adopted, the side curve of the supporting paper block 4 has a larger contact part with the supplementary paper block 6, and the supportable range of the supporting paper block 4 can be increased. At this time, if the local portion of the composite corrugated cardboard is flattened by an external force, the flattened portion is restored and expanded by beating the local portion, the supplementary paper block 6 is filled in the portion under the effect of the self-weight of the supplementary paper block 6, or the supplementary paper block 6 beside the portion is squeezed, the pressure contact end 9 of the supplementary paper block 6 allows the adjacent supplementary paper block 6 to transmit the pressure after being pressed by the outside, the contact area between the adjacent supplementary paper blocks 6 is increased by the pressure contact surface 10, and the pressure bearing capacity of the pressure contact end 9 is improved. The paper supplementing blocks 6 are filled into the flattened parts under the action of external pressing force, the parts are enabled to be bulged, the paper supplementing blocks 6 at other parts can sequentially fill gaps, and self repair after local damage is achieved.
In the repairing process, the supplementary paper block 6 is forced to move, the twisted side edge of the supporting paper block 4 is provided with a curve which can guide the supplementary paper block 6 to slide downwards to supplement a lower broken area, and the curve of the side edge also enables the supplementary paper block 6 to slide downwards and rotate, so that the probability of stopping the supplementary paper block in the supplementary channel 5 is reduced. When the replenishing paper block 6 moves, the foam particles 8 in the replenishing paper block 6 can increase the compressive strength of the replenishing paper block 6, and the replenishing paper block 6 is not easily deformed. Meanwhile, the foam particles 8 flow out and fill the supplementary channel 5 after the supplementary paper block 6 is crushed or punctured, and fill gaps, so that the compressive strength of the damaged part of the composite corrugated board is repaired and increased.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
