Description

[Technical field]

[0001] The present invention relates to the technical field of packaging of goods, and in particular to the structure, processing method and processing equipment of honeycomb-structured impact-resistant paper pad. [Background technology]

[0002] As logistics develops, the transportation of documents and goods has been realized through logistics and postal services, and the above-mentioned packaging materials are used in large quantities. The types of goods are diverse, and honeycomb-structured shock-resistant paper pads are widely used in packaging used to transport fragile goods.

[0003] In the prior art, the shock-resistant materials used are, first, foam shock-absorbing plates or blocks, second, air bubble cushioning, and third, honeycomb-structured shock-resistant paper pads, which are used as shock-resistant packaging when transporting fragile items. The first and second shock-resistant packaging mentioned above are both large in volume, are not environmentally friendly, and have problems such as the difficulty of recycling and disposing of packaging waste. The honeycomb-structured shock-resistant paper pad needs to be stretched before use, and the shock-absorbing effect is obtained by stretching. In the prior art, the honeycomb-structured shock-resistant paper pad was stretched manually or by machine, but the paper mesh-shaped shock-resistant pad is made of paper and has elasticity, so when it is stretched and not fixed, it returns to its original state before stretching due to its elasticity, which is inconvenient to use. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention aims to solve the technical problem associated with the inconvenience of use in that, when a paper mesh-shaped impact-resistant pad is stretched, it returns to its original state before stretching due to its elasticity, and to provide a structure, processing method, and processing equipment for a honeycomb-structured impact-resistant paper pad, which is based on a conventional honeycomb-structure impact-resistant paper pad structure and changes the conventional structure of a paper mesh-shaped impact-resistant pad through a molding process, so that the shape of the paper mesh-shaped impact-resistant pad is fixed and does not return to its original state before stretching even after it is stretched. [Means for solving the problem]

[0005] In order to achieve the above-mentioned objectives, the technical method adopted by the present invention is a honeycomb-structured impact-resistant paper pad structure, which is formed by bonding the end faces of paper pieces having a honeycomb structure to each other at equal intervals.

[0006] The end faces of the paper pieces have a honeycomb structure, and the portions where the paper pieces are not glued have bent curved portions at both the top and bottom ends, and the portions where the paper pieces are glued have intermediate curved portions.

[0007] The method for shaping the honeycomb-structured impact-resistant paper pad is realized by stretching and shaping a contracted mesh-like impact-resistant paper pad, which is made by bonding a set of parallel-arranged paper pieces together at equal intervals.

[0008] Step A1: The contracted mesh-like impact-resistant paper pad is stretched and expanded to form an impact-resistant paper pad with a honeycomb structure in which hexagonal-shaped pieces of paper are attached to each other at equal intervals.

[0009] Step A2: A honeycomb-structured impact-resistant paper pad is passed through a folded scraper while maintaining a constant stretching stress, so that both the top and bottom ends of the stretched hexagonal-shaped paper piece are curved to one side.

[0010] In step A3, the hexagonal mesh-like impact-resistant paper pad formed in step A2, in which both the upper and lower ends of the hexagonal-shaped paper pieces are curved to one side, is passed through opposing rollers of the designed thickness and rolled to a fixed shape, resulting in an impact-resistant paper pad with a honeycomb structure that has the designed thickness, has folded curved portions at both the upper and lower ends of the parts where the paper pieces are not glued, and has an intermediate curved portion in the part where the paper pieces are glued.

[0011] The design spacing of the opposing rollers for regular rolling is designed so that the distance between the outer circles of the opposing rollers is less than or equal to 30-50% of the design thickness of the honeycomb-structured impact-resistant paper pad before it is put into the rollers.

[0012] The honeycomb structure impact resistant paper pad forming device comprises a frame section, a scraper section and a forming rolling section.

[0013] The scraper part includes a flexible upper scraper and a flexible lower scraper, the flexible upper scraper and the flexible lower scraper are fixed at an incline to the frame part, and the distance between the flexible upper scraper and the flexible lower scraper is smaller than the design thickness of the honeycomb structure impact-resistant paper pad.

[0014] The said shaping rolling section comprises a rigid forming roller, the said rigid forming roller is fixed to a frame section, and the distance of the outer circle of the rigid forming roller is less than or equal to 30-50% of the design thickness of the honeycomb structure impact resistant paper pad before being put into the rigid forming roller. Effect of the Invention

[0015] The honeycomb impact-resistant paper pad structure has the advantages of being simple in structure, not deforming, and easy to use.

[0016] The method of shaping the honeycomb-structured impact-resistant paper pad is simple, and can be completed in one go by stretching and shaping.

[0017] The honeycomb structure shock-resistant paper pad forming device is simple in structure and efficient. [Brief description of the drawings]

[0019] The present invention will be described in detail below in conjunction with the drawings.

[0020] Please refer to the figure. The figure shows a shock-resistant paper pad structure with a honeycomb structure, and the shock-resistant paper pad structure is constructed by pasting the end faces of a set of paper pieces with a honeycomb structure to each other at equal intervals. The end faces of the paper pieces 1 have a honeycomb structure, and the upper and lower ends of the non-bonded parts of the paper pieces 1 are provided with bent curved parts 1-1, and the bonded parts of the paper pieces 1 are provided with intermediate curved parts 1-2.

[0021] Bend curved sections 1-1 are provided at both the top and bottom ends of the non-glued portion of the paper piece 1, and a middle curved section 1-2 is provided at the glued portion of the paper piece 1. By providing bend curved sections 1-1 at both the top and bottom ends of the honeycomb-structured impact-resistant paper pad 3 and a middle curved section 1-2 at the glued portion of the paper piece 1, the elasticity of the paper piece 1 prevents the paper pieces 1 from returning to their original parallel, approaching state even after molding, and further enhances the impact absorption effect of the honeycomb-structured impact-resistant paper pad 3.

[0022] The standard method for making a honeycomb-structured impact-resistant paper pad is to stretch and mold a shrunk mesh-like impact-resistant paper pad made by bonding a set of parallel arranged paper pieces together at equal intervals, and then carry out the following steps.

[0023] Step A1. The contracted mesh-like impact-resistant paper pad is stretched and expanded to form a honeycomb-structured impact-resistant paper pad in which hexagonal-shaped pieces of paper are attached to each other at equal intervals.

[0024] The purpose of step A1 is to first stretch it into an unfolded state.

[0025] Step A2. The honeycomb-structured impact-resistant paper pad is passed through a folded scraper while maintaining a constant stretching stress, so that both the top and bottom ends of the stretched hexagonal-shaped paper piece are curved to one side.

[0026] Through the action of the folding scraper, the stretched and unfolded honeycomb-structured impact-resistant paper pad is uniformly unfolded, and at the same time, both the upper and lower ends of the stretched hexagonal paper pieces are curved to one side in the same direction, thereby preparing the subsequent process of forming the curved parts.

[0027] Step A3: The hexagonal mesh-shaped impact-resistant paper pad, in which both the upper and lower ends of the hexagonal paper pieces are curved to one side according to step A2, is passed through opposing rollers with a designed interval to form a fixed roll, thereby forming an impact-resistant paper pad with a honeycomb structure having a designed thickness, with folded curved parts formed at both the upper and lower ends of the non-bonded parts of the paper pieces, and with a middle curved part provided in the bonded parts of the paper pieces.

[0028] By rolling the paper piece with the opposing rollers in a fixed shape, both the top and bottom ends of the paper piece completed in step A2 are curved to one side in the same direction, so that the opposing rollers form bent curved portions at both the top and bottom ends of the non-glued portion of the paper piece.

[0029] The design interval of the regular rolling of the opposing rollers is designed so that the distance between the outer circles of the opposing rollers is less than or equal to 30-50% of the design thickness of the honeycomb-structured impact-resistant paper pad before it is put into the opposing rollers.

[0030] In the embodiment of the present invention, the constant shape rolling in step 3 is repeated two or three times to more reliably form a bent curved portion that does not return to its original shape due to elasticity.

[0031] In an embodiment of the present invention, the pair of opposing rollers having a designed gap in step A3 are hot rollers, and the top and bottom ends of the unbonded portion of the paper piece are rolled with the hot rollers to form a bent curved portion.

[0032] The honeycomb structure impact resistant paper pad forming device comprises a frame section, a scraper section and a forming rolling section.

[0033] The scraper unit includes a flexible upper scraper 2-1 and a flexible lower scraper 2-2, which are inclined and fixed to a frame unit 5. The distance between the flexible upper scraper 2-1 and the flexible lower scraper 2-2 is smaller than the thickness of the impact-resistant paper pad 3 with a honeycomb structure.

[0034] The purpose of installing the flexible upper scraper 2-1 and the flexible lower scraper 2-2 is to evenly spread the honeycomb-structured impact-resistant paper pad 3 while at the same time allowing both the upper and lower ends of the paper piece to bend to one side in the same direction in preparation for the process of forming bending curves at both the upper and lower ends of the parts of the paper piece that are not glued by the opposing rollers.

[0035] The said standard rolling section comprises a rigid forming roller 4-1, the rigid forming roller 4-1 is fixed to a frame section 5, and the distance of the outer circle of the rigid forming roller 4-1 is less than or equal to 30-50% of the design thickness of the honeycomb-structured impact-resistant paper pad 3 before it is put into the rigid forming roller 4-1.

[0036] In the embodiment of the present invention, the shaping rolling section further includes a rigid forming roller 4-2, which is fixed to the frame section 5, and the distance of the outer circle of the rigid forming roller 4-2 is less than or equal to 50-65% of the design thickness of the honeycomb-structured impact-resistant paper pad 3 before being inserted into the rigid forming roller 4-2. The inlet end of the rigid forming roller 4-2 corresponds to the outlet end of the rigid forming roller 4-1. The rigid forming roller 4-2 is used to form the bent curved portion, which makes the shaping more uniform.

[0037] In the embodiment of the present invention, the flexible upper scraper 2-1 and the flexible lower scraper 2-2 are elastic pieces with brushes or sawtooth. When using the flexible upper scraper 2-1 and the flexible lower scraper 2-2, they will not damage the impact-resistant paper pad 3 with honeycomb structure.

[0038] In an embodiment of the present invention, the rigid forming roller 4-1 or the rigid secondary forming roller 4-2 is a hot roller. [Explanation of symbols]
