Description

Technical field of the invention

[0001] The present invention relates to a packaging material for objects and in particular a shock-absorbing honeycomb cardboard structure and a processing device for it. State of the art

[0002] With the development of logistics, people can ship documents, articles, and other items. Based on the above, packaging materials are widely used. Since there are many types of items, shock-absorbing honeycomb cardboard is frequently used, especially when packaging fragile items for transport.

[0003] Existing technology uses shock-absorbing materials, such as shock-absorbing foam sheets, bubble wrap bags, or shock-absorbing honeycomb cardboard, to create shock-absorbing packaging for transporting fragile items. Both shock-absorbing foam sheets and bubble wrap bags have the drawbacks of being bulky, not environmentally friendly, and difficult to recycle and dispose of as packaging waste. To achieve a shock-absorbing effect, shock-absorbing honeycomb cardboard must be stretched before use. Prior art uses manual or machine methods to stretch shock-absorbing honeycomb cardboard. After stretching, the grid-like, shock-absorbing cardboard completely returns to its original pre-stretch state due to its elasticity, which causes problems in use. Object of the invention

[0004] The object of the invention is to solve the problem that, after stretching, the grid-like, shock-absorbing cardboard returns to its original state due to its elasticity, which causes problems in its use. The present invention is based on the structure of existing shock-absorbing honeycomb cardboard. Through the forming process, the existing structure of the grid-like, shock-absorbing paper is modified to ensure that the shape of the grid-like, shock-absorbing paper does not return to its original state after stretching and forming. To solve the above problem, the present invention discloses a shock-absorbing honeycomb cardboard structure and a processing device for it.

[0005] The technical solutions used to solve the problem are described below: A shock-absorbing honeycomb cardboard structure is used, consisting of a series of paper strips with a honeycomb structure, the end surfaces of which are glued together at regular intervals.

[0006] The end surfaces of the paper strips represent a honeycomb structure, with the upper and lower ends of the unglued area of ​​each paper strip each having an edge fold section and the glued area of ​​each paper strip having a central fold section.

[0007] A forming device is used for the shock-absorbing honeycomb board, which includes a frame section, an edge scraper section and a forming roller section.

[0008] The edge scraper section comprises an upper flexible scraper and a lower flexible scraper, wherein the upper flexible scraper and the lower flexible scraper are attached obliquely to the frame section and the distance between the upper flexible scraper and the lower flexible scraper is less than the thickness of the shock-absorbing honeycomb board.

[0009] The forming roller section comprises a rigid forming roller pair, wherein the rigid forming roller pair is attached to the frame section and the distance between the outer circles of the rigid forming rollers is less than or equal to 30 to 50% of the thickness of the shock-absorbing honeycomb board before entering the rigid forming roller pair. Advantageous effects of the present invention:

[0010] The shock-absorbing honeycomb cardboard structure has the advantages of a simple structure, no deformation and easy use;

[0011] The forming device for the shock-absorbing honeycomb cardboard has a simple structure and enables high efficiency.

Detailed description of preferred embodiments

[0013] Reference is made to the figures, which show a shock-absorbing honeycomb cardboard structure. The shock-absorbing cardboard structure consists of a series of paper strips with a honeycomb structure, the end faces of which are glued together at regular intervals, wherein the end faces of the paper strips 1 represent a honeycomb structure, the upper and lower ends of the unglued section of each paper strip 1 are each provided with an edge fold 1-1, and the glued area of ​​each paper strip 1 is provided with a central fold 1-2.

[0014] Since the upper and lower ends of the unglued section of each paper strip 1 are each provided with an edge fold section 1-1, and the glued section of each paper strip 1 is provided with a central fold section 1-2, the shock-absorbing honeycomb cardboard 3 can, after forming, assume a state in which it does not return to its original state, in which the paper strips 1 are parallel to each other again due to elastic recovery. This improves the shock-absorbing effect of the shock-absorbing honeycomb cardboard 3.

[0015] A forming device is used for the shock-absorbing honeycomb board, which includes a frame section, an edge scraper section and a forming roller section.

[0016] The edge scraper section comprises an upper flexible scraper 2-1 and a lower flexible scraper 2-2, wherein the upper flexible scraper 2-1 and the lower flexible scraper 2-2 are attached obliquely to the frame section 5 and the distance between the upper flexible scraper 2-1 and the lower flexible scraper 2-2 is less than the thickness of the shock-absorbing honeycomb board 3.

[0017] The purpose of the arrangement of the upper flexible scraper 2-1 and the lower flexible scraper 2-2 is to stretch the shock-absorbing honeycomb cardboard 3 evenly. Simultaneously, the edge creases are formed by the pair of rollers at the upper and lower ends of the unglued sections of the paper strips to prepare them for the folding process.

[0018] The forming roller section comprises a rigid forming roller pair 4-1, wherein the rigid forming roller pair 4-1 is attached to the frame section 5 and the distance between the outer circles of the rigid forming rollers 4-1 is less than or equal to 30 to 50% of the thickness of the shock-absorbing honeycomb board 3 before entering the rigid forming roller pair 4-1.

[0019] In this embodiment of the present invention, the forming roller section further comprises a secondary rigid forming roller pair 4-2, wherein the secondary rigid forming roller pair 4-2 is attached to the frame section 5, the distance between the outer circles of the secondary rigid forming rollers 4-2 is less than or equal to 50 to 65% of the thickness of the shock-absorbing honeycomb board 3 before entering the secondary rigid forming roller pair 4-2, and the inlet end of the secondary rigid forming roller pair 4-2 corresponds to the outlet end of the rigid forming roller pair 4-1. The secondary rigid forming roller pair 4-2 serves to further form the edge creases.

[0020] In this embodiment of the present invention, the upper flexible scraper 2-1 and the lower flexible scraper 2-2 are brushes or elastic parts with teeth. The upper flexible scraper 2-1 and the lower flexible scraper 2-2 ensure that the shock-absorbing honeycomb cardboard 3 is not damaged during the process.

[0021] In this embodiment of the present invention, the rigid forming roller pair 4-1 or the secondary rigid forming roller pair 4-2 are hot rollers.
