Abstract
Description
Technical Field
[0001] The invention relates to the technical field of corrugated paper, and in particular to a high-strength composite corrugated paper with a multi-layer structure and a manufacturing method thereof. Background Art
[0002] High-strength corrugated paper is widely used in the packaging industry due to its excellent pressure-bearing capacity and lightweight characteristics. Traditional high-strength corrugated paper usually uses a corrugated layer with a symmetrical structure, and forms a triangular three-dimensional structure by bonding the corrugated paper and the surface paper layer to obtain higher strength. However, since the corrugated layer is a vertically symmetrical structure, the triangular three-dimensional structure formed by the corrugated layer has a large rigidity. When external forces act on the corrugated paper, the corrugated paper cannot deform adaptively to buffer the forces. This causes the existing high-strength corrugated paper to easily break when subjected to impact and has poor toughness. In addition, the rigid structure of the corrugated paper limits its ability to deform when subjected to impact, which in turn affects its impact resistance. Summary of the invention

DETAILED DESCRIPTION
[0046] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.
[0047] Depend on Figures 1 to 4It can be seen that in this embodiment, the multi-layer high-strength composite corrugated paper 74 includes a corrugated paper layer 1, a first paper layer 2 arranged at the bottom of the corrugated paper layer 1, and a second paper layer 3 arranged at the top of the corrugated paper layer 1; the corrugated paper layer 1 includes a plurality of deformation segments 13 and a plurality of support segments 11; the corrugated paper layer 1 is formed by alternating the deformation segments 13 and the support segments 11; the connection between the top of the deformation segment 13 and the top of the support segment 11 is connected to the second paper layer 3; the connection between the bottom of the deformation segment 13 and the bottom of the support segment 11 is connected to the first paper layer 2; a deformation activity cavity 4 is enclosed and formed between the deformation segment 13, the support segment 11 and the first paper layer 2; a paper tube 5 is movably arranged in the deformation activity cavity 4; the first paper layer 2 is provided with an elastic member 6; the elastic member 6 is used to make the paper tube 5 abut against the deformation segment 13. In this embodiment, the rigidity of the support segment 11 is greater than the rigidity of the deformation segment 13.
[0048] Among them, the deformation section 13 has a certain elasticity and deformation degree, and can undergo a certain deformation under the action of external force; the elastic member 6 can be elastic paper or elastic plastic material; the paper tube 5 has a certain strength; in addition, the corrugated paper layer 1 is formed by alternating the deformation section 13 and the support section 11, thereby forming a wavy structure.
[0049] This embodiment can buffer the external force exerted on the corrugated paper by arranging the high-strength composite corrugated paper 74 into an asymmetric shape on the upper and lower sides.
[0050] In addition, by arranging the paper tube 5 and the elastic member 6 in the deformation activity cavity 4, when the external force applied to the corrugated paper is small, the deformation segment 13 is less recessed in the direction of the deformation activity cavity 4, and the deformation segment 13 drives the paper tube 5 to move in the direction of the support segment 11 during the recessing process. During the movement of the paper tube 5, since the elastic member 6 and the paper tube 5 are abutted against each other, the paper tube 5 can transfer the elastic force of the elastic member 6 to the deformation segment 13, thereby enhancing the impact resistance and buffering capacity of the high-strength composite corrugated paper 74.
[0051] When the external force applied to the corrugated paper is large, the deformation segment 13 is greatly sunken in the direction of the deformation activity cavity 4. After the paper tube 5 is squeezed by the deformation segment 13 to abut against the support segment 11, the deformation segment 13, the paper tube 5 and the support segment 11 form a triangular three-dimensional support structure, so that the corrugated paper is transformed into a rigid support state, so as to improve the ultimate strength of the high-strength composite corrugated paper 74.
[0052] In this embodiment, the deformation section 13 is concave inwardly toward the deformation activity cavity 4 to form an inner concave portion 14; the elastic member 6 abuts against the inner concave portion 14. Through the above arrangement, the deformation section 13 is formed into an elastic structure that bends toward the deformation activity cavity 4 in a natural state, so that it can be ensured that under the action of an external force, the deformation section 13 is deformed toward the deformation activity cavity 4, thereby pushing the paper tube 5 to move toward the support section 11.
[0053] In this embodiment, the cross-sectional shape of the paper tube 5 is circular. Through the above arrangement, the paper tube 5 is cylindrical as a whole, which has the advantage of high strength.
[0054] In this embodiment, the elastic member 6 includes a connecting plate 61 and an elastic arm 62 arranged on the connecting plate 61; the elastic arm 62 is arranged obliquely with the connecting plate 61; a first give-way groove 15 is penetrated through the bottom of the deformation section 13; a second give-way groove 12 is penetrated through the supporting section 11; in one of the deformation activity cavities 4, the connecting plate 61 is arranged on the top of the first surface paper layer 2 and is arranged at one end of the paper tube 5 in the deformation activity cavity 4; the elastic arm 62 passes through the first give-way groove 15 and the second give-way groove 12 in sequence and then enters the adjacent deformation activity cavity 4, and abuts against the other end of the paper tube 5 in the adjacent deformation activity cavity 4.
[0055] In order to make full use of the space in the corrugated paper, the connecting plate 61 and the elastic arm 62 are respectively arranged in two different deformation activity chambers 4; when the external force applied to the corrugated paper is large, the deformation segment 13 is greatly depressed in the direction of the deformation activity chamber 4, and the paper tube 5 is squeezed by the deformation segment 13 to move in the direction of the support segment 11 until the paper tube 5 abuts against the support segment 11, and at the same time the elastic arm 62 is pushed out of the second make way groove 12, so that the deformation segment 13, the paper tube 5 and the support segment 11 form a triangular three-dimensional support structure, so that the corrugated paper is transformed into a rigid support state, so as to improve the ultimate strength of the high-strength composite corrugated paper 74; after the external force disappears, the elastic arm 62 is reset and re-enters the deformation activity chamber 4 from the second make way groove 12, pushing the paper tube 5 and the deformation segment 13 to reset, thereby accelerating the recovery of the corrugated paper.
[0056] In this embodiment, the outer circumference of the paper tube 5 is provided with a limiting ring groove 51 that cooperates with the elastic arm 62. The limiting ring groove 51 is circumferentially arranged on the outer wall of the paper tube 5, so that the limiting ring groove 51 can be limited with the elastic arm 62 in the axial direction of the paper tube 5, thereby enhancing the overall stability of the high-strength composite corrugated paper 74.
