Therefore, the terms of direction are used to explain and understand the utility model, rather than to limit the utility model. In addition, in the drawings, the structures similar or identical are indicated by the same reference numerals.

[0039] Referring to Figures 1 to 5 It shows an embodiment of the pulp molding inner packaging structure provided by the utility model, and the structure and working principle of the pulp molding inner packaging structure will be described in detail below with reference to the drawings in the specification. The pulp molding inner packaging structure is used for the inner packaging of a display screen 200, which comprises: side edge paper plastic wrapping members 10 wrapped on the upper, lower, left and right side edges of the display screen 200 respectively; diagonal paper plastic wrapping members 20 wrapped on the four corners of the display screen 200 respectively; wherein the outer side surfaces of the side edge paper plastic wrapping members 10 and the diagonal paper plastic wrapping members 20 are overlapped with paper plastic folding edges 2, and the paper plastic folding edges 2 are formed by outwardly folding the side edges of the side edge paper plastic wrapping members 10 and the diagonal paper plastic wrapping members 20.

[0040] In a specific implementation, the pulp molding inner packaging structure is mainly used for inner packaging of the display screen 200, provides safety protection for the display screen 200, and the application scenario is mainly the factory packaging or transportation of the display screen 200 product. When the display screen 200 product is shipped, inner and outer packaging protection treatment is performed. The inner packaging is a packaging structure directly contacting the display screen 200, which is mainly used to prevent the display screen 200 from being damaged due to inertial impact or jolt during handling or transportation. The outer packaging is a structure containing the entire inner packaging, which cooperates with the inner packaging to prevent the display screen 200 product from being bumped or scratched during handling or transportation. The pulp molding inner packaging structure of the embodiment mainly adopts a pulp molding structure design. The pulp molding is a three-dimensional structure packaging material formed by a mold under certain pressure and shape, and the molded pulp molding is a cavity structure composed of a surface. The pulp molding inner packaging structure includes a side pulp wrapping piece 10 and a diagonal pulp wrapping piece 20. The side pulp wrapping piece 10 and the diagonal pulp wrapping piece 20 are wrapping structures adapted to the shape of the side and diagonal of the display screen 200, but the side pulp wrapping piece 10 and the diagonal pulp wrapping piece 20 protect different parts of the display screen 200. The side pulp wrapping piece 10 is a "one" shaped wrapping structure, which is wrapped around the upper, lower, left and right four sides of the display screen 200, and is mainly used to protect the four sides of the display screen 200. The pulp wrapping of the diagonal pulp wrapping piece 20 is an "L" shaped wrapping structure, which is wrapped around the four corners of the display screen 200, and the diagonal pulp wrapping piece 20 is mainly used to protect the four corners of the display screen 200. Specifically, the inner side of the side pulp wrapping piece 10 and the diagonal pulp wrapping piece 20 is a groove designed to fit the side and diagonal profile of the display screen 200, which is wrapped by cooperating with the shape of the side and diagonal of the display screen 200. The side pulp wrapping piece 10 and the diagonal pulp wrapping piece 20 together have at least eight pulp pieces, which package and protect the upper, lower, left and right four sides of the display screen 200 and the four corners of the display screen 200. The outer side of the side pulp wrapping piece 10 and the diagonal pulp wrapping piece 20 is overlaid with a pulp folding edge 2, such as Figures 2 to 4As shown, the paper-plastic folded edge 2 is specifically formed by outwardly folding the side edges of the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20, and is integrally connected with the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20. The paper-plastic folded edge 2 is superimposed on the outer side of the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20, i.e., on the side of the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20 that faces away from the display screen 200, and is in conformity with the shape of the outer side of the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20. In order to meet the packaging size requirements of the display screen 200, the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20 can be superimposed with the paper-plastic folded edge 2 on multiple different outer sides, and the actual packaging requirements can be designed accordingly. By superimposing the paper-plastic folded edge 2 on the outer side of the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20, the outer side of the paper-plastic edge covering of the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20 has an additional layer of paper-plastic structure, and the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20 both have two layers of paper-plastic structure from inside to outside, and have higher edge covering structure strength. In actual packaging scenarios, the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20 wrap the four edges and four corners of the display screen 200, respectively, and the paper-plastic folded edge 2 is superimposed on the outer side of the side paper-plastic edge covering member 10 and the diagonal paper-plastic edge covering member 20, and is in contact with the inner wall of the outer packaging structure such as a carton to provide support. The display screen 200 and the outer packaging structure have two layers of paper-plastic structure therebetween, and compared with the traditional single-layer paper-plastic structure, the structural strength is improved, the impact resistance is stronger, and the stability and safety of the packaging of the large-size display screen 200 product can be effectively improved.

[0041] The pulp molding inner packaging structure of the embodiment adopts environmentally friendly fully degradable pulp molding, and the structural strength of the pulp molding is improved through the structure design of edge covering and edge folding. The inner packaging structure of the display screen product is improved in terms of load bearing and impact resistance, and the stability and safety of the packaging of the large-size display screen product are greatly improved.

[0042] In an embodiment, with reference to Figures 1 to 5The side paper-plastic edging component 10 includes an upper side paper-plastic edging 11 and a lower side paper-plastic edging 12. The upper side paper-plastic edging 11 and the lower side paper-plastic edging 12 respectively wrap around the upper and lower sides of the display screen 200. The upper side paper-plastic edging 11 and the lower side paper-plastic edging 12 are overlapped on at least one outer surface of the display screen 200 facing away from it in the normal direction. In a specific implementation, the side paper-plastic edging component 10 includes an upper side paper-plastic edging 11 and a lower side paper-plastic edging 12, which wrap around the upper and lower sides of the display screen 200 respectively to protect the upper and lower sides of the display screen 200. The upper and lower paper-plastic edging edges 11 and 12 are overlapped on at least one outer surface of the display screen 200 facing away from it in the normal direction. Specifically, the normal direction of the display screen 200 is perpendicular to the screen of the display screen 200. Figure 1 As shown, direction a represents the normal direction of the display screen, and direction b represents the horizontal direction of the display screen 200. The upper side paper-plastic edging 11 and the lower side paper-plastic edging 12 have two outer surfaces facing away from the display screen 200 in the normal direction, namely the front and rear outer surfaces. At least one of these two outer surfaces is overlapped with the paper-plastic folded edge 2. In this embodiment, the upper side paper-plastic edging 11 is overlapped with the paper-plastic folded edge 2 on both outer surfaces in the normal direction of the display screen 200, that is, the upper side paper-plastic edging 11 adopts two-sided folding. According to the ridge size of the bottom edge of the display screen 200, the lower side paper-plastic edging 12 is overlapped with the paper-plastic folded edge 2 on only one outer surface in the normal direction of the display screen 200, that is, the lower side paper-plastic edging 12 adopts one-sided folding. In actual packaging scenarios, by overlapping the upper side paper-plastic edge 11 and the lower side paper-plastic edge 12 with the paper-plastic folded edge 2, the strength of the upper and lower edge structures is enhanced. The paper-plastic folded edge 2 fits and supports the outer packaging structure. The supporting force of the display screen 200 can be applied to the outer packaging structure through the paper-plastic folded edge 2, which enhances stability and improves the protection of the display screen 200 by the packaging structure.

[0043] In one embodiment, reference is made to Figures 1 to 5The side paper-plastic edging component 10 includes a left side paper-plastic edging component 13 and a right side paper-plastic edging component 14. The left side paper-plastic edging component 13 and the right side paper-plastic edging component 14 respectively wrap around the left and right sides of the display screen 200. Specifically, the left side paper-plastic edging component 10 includes a left side paper-plastic edging component 13 and a right side paper-plastic edging component 14. The left side paper-plastic edging component 13 and the right side paper-plastic edging component 14 respectively wrap around the left and right sides of the display screen 200 to protect the left and right sides of the display screen 200. The left side paper-plastic edging component 13 and the right side paper-plastic edging component 14 have overlapping paper-plastic folded edges 2 on the outer surface of the display screen 200 facing away from the display screen 200. Specifically, the normal direction of display screen 200 is the direction perpendicular to the screen of display screen 200, such as... Figure 1 As shown, direction a represents the normal of the display screen, and direction b represents the horizontal direction of the display screen 200. The left and right paper-plastic edging edges 13 and 14 have two outer surfaces facing away from the display screen 200 in the normal direction. Both outer surfaces are overlapped with paper-plastic folded edges 2, meaning the left and right paper-plastic edging edges 13 and 14 employ double-sided folds. In actual packaging scenarios, by overlapping the paper-plastic folded edges 2 on the left and right paper-plastic edging edges 13 and 14, the strength of the left and right edging structures is enhanced. The paper-plastic folded edges 2 fit snugly against the outer packaging structure, and the supporting force of the display screen 200 can be applied to the outer packaging structure through the paper-plastic folded edges 2, enhancing stability and improving the protection of the display screen 200 by the packaging structure.

[0044] In one embodiment, reference is made to Figures 1 to 5 The diagonal paper-plastic edging component 20 includes a top left corner paper-plastic edging component 21 and a top right corner paper-plastic edging component 22. The top left corner paper-plastic edging component 21 and the top right corner paper-plastic edging component 22 respectively wrap around the top left and top right corners of the display screen 200. The top left corner paper-plastic edging component 21 and the top right corner paper-plastic edging component 22 overlap the paper-plastic folded edge 2 on the outer surface of the display screen 200 in the normal direction and horizontal direction, away from the display screen 200. In specific implementation, the diagonal paper-plastic edging component 20 includes a top left corner paper-plastic edging component 21 and a top right corner paper-plastic edging component 22, which respectively wrap around the top left and top right corners of the display screen 200 to protect the top left and top right corners of the display screen 200. The upper left and upper right corner paper-plastic edging edges 21 and 22 are both overlapped on the outer surfaces of the display screen 200 in both the normal direction and horizontal direction, away from the display screen 200. Specifically, the normal direction of the display screen 200 is the direction perpendicular to the screen of the display screen 200, such as... Figure 1As shown, the normal direction of the display screen is represented by direction a, and the lateral direction of the display screen 200 is represented by direction b. The two outer sides of the display screen 200, which are away from the display screen 200 in the normal direction of the display screen 200, are both overlaid with the paper plastic folding edge 2, that is, the left upper corner paper plastic wrapping edge 21 and the right upper corner paper plastic wrapping edge 22 adopt three-edge folding. In the actual packaging scenario, by overlaying the paper plastic folding edge 2 on the left upper corner paper plastic wrapping edge 21 and the right upper corner paper plastic wrapping edge 22, the strength of the wrapping structure of the two corners at the top is strengthened, the paper plastic folding edge 2 is adhered to the support of the outer packaging structure, the supporting force of the display screen 200 can be applied to the outer packaging structure through the paper plastic folding edge 2, the stability is enhanced, and the protection of the packaging structure on the display screen 200 is improved.

[0045] In an embodiment, referring to Figures 1 to 5 , the diagonal paper plastic wrapping member 20 includes a left lower corner paper plastic wrapping edge 23 and a right lower corner paper plastic wrapping edge 24, which are wrapped around the left lower corner and the right lower corner of the display screen 200, respectively. In particular embodiments, the diagonal paper plastic wrapping member 20 includes a left lower corner paper plastic wrapping edge 23 and a right lower corner paper plastic wrapping edge 24, which are wrapped around the left lower corner and the right lower corner of the display screen 200, respectively, to protect the left lower corner and the right lower corner of the display screen 200. The left lower corner paper plastic wrapping edge 23 and the right lower corner paper plastic wrapping edge 24 are both overlaid with the paper plastic folding edge 2 on at least one outer side of the display screen 200 in the normal direction of the display screen 200. Specifically, the normal direction of the display screen 200 is perpendicular to the screen of the display screen 200, and the lateral direction of the display screen 200 is represented by direction b. The two outer sides of the display screen 200, which are away from the display screen 200 in the normal direction of the display screen 200, are both overlaid with the paper plastic folding edge 2, that is, the left upper corner paper plastic wrapping edge 21 and the right upper corner paper plastic wrapping edge 22 adopt three-edge folding. In the actual packaging scenario, by overlaying the paper plastic folding edge 2 on the left upper corner paper plastic wrapping edge 21 and the right upper corner paper plastic wrapping edge 22, the strength of the wrapping structure of the two corners at the top is strengthened, the paper plastic folding edge 2 is adhered to the support of the outer packaging structure, the supporting force of the display screen 200 can be applied to the outer packaging structure through the paper plastic folding edge 2, the stability is enhanced, and the protection of the packaging structure on the display screen 200 is improved.

[0046] Further, referring toFigure 1 、 Figure 2 、 Figure 5 and Figure 6 The pulp molding inner packaging structure further comprises a corner guard paperboard piece 30, which is attached to the outer side of the lower left paper plastic edge wrapping 23 and the outer side of the lower right paper plastic edge wrapping 24 along the diagonal direction of the display screen 200. Specifically, the bottom edge of the display screen 200 bears a large pressure, and in the drop test during the transportation process, the two corners of the bottom edge of the display screen 200 are the two most fragile corners. Therefore, the embodiment strengthens the protection capability of the two corners of the bottom edge of the display screen 200 by the corner guard paperboard piece 30. The two corner guard paperboard pieces 30 are designed to cooperate with the lower left paper plastic edge wrapping 23 and the lower right paper plastic edge wrapping 24 respectively. The corner guard paperboard piece 30 is designed by using paperboard material and can be any paperboard structure. The overall shape of the corner guard paperboard piece 30 is designed as an "L" shape, which is adapted to the shape of the outer side of the lower left paper plastic edge wrapping 23 and the lower right paper plastic edge wrapping 24. The two corner guard paperboard pieces 30 are respectively attached to the outer side of the lower left paper plastic edge wrapping 23 and the outer side of the lower right paper plastic edge wrapping 24 along the diagonal direction of the display screen 200, and are kept attached to the outer side of the lower left paper plastic edge wrapping 23 and the lower right paper plastic edge wrapping 24. In the actual packaging scene, the corner guard paperboard piece 30 is attached and supported by the outer packaging structure, the corner strength of the packaging bottom is increased, and when the display screen 200 package collides diagonally or falls, the corner guard paperboard piece 30 deforms to provide a buffering effect. The impact force between the ground and the packaging corner is dispersed by the corner guard paperboard piece 30, thereby improving the protection capability of the display screen 200 during the transportation process.

[0047] Further, with reference to Figures 6 to 9The corner protection paperboard piece 30 comprises an inner corner protection paperboard 31, an outer corner protection paperboard 32 and a middle honeycomb paperboard 33. The inner corner protection paperboard 31 is attached to the outer side of the lower left corner plastic wrapping 23 and the outer side of the lower right corner plastic wrapping 24. The middle honeycomb paperboard 33 is attached to the outer side of the inner corner protection paperboard 31. The outer corner protection paperboard 32 is attached to the outer side of the middle honeycomb paperboard 33. In a specific implementation, the corner protection paperboard piece 30 mainly comprises the inner corner protection paperboard 31, the outer corner protection paperboard 32 and the middle honeycomb paperboard 33. The inner corner protection paperboard 31 and the outer corner protection paperboard 32 are similar in shape and are both "L"-shaped paperboard structures. The inner corner protection paperboard 31 of the two corner protection paperboard pieces 30 is respectively attached to the outer side of the lower left corner plastic wrapping 23 and the outer side of the lower right corner plastic wrapping 24 and is attached and installed along the diagonal direction of the display screen 200. The middle honeycomb paperboard 33 is a honeycomb paperboard structure and comprises a plurality of hexagonal structures that are closely connected. The middle honeycomb paperboard 33 is attached to the outer side of the inner corner protection paperboard 31. The outer corner protection paperboard 32 is attached to the outer side of the middle honeycomb paperboard 33. The middle honeycomb paperboard 33 is sandwiched between the inner corner protection paperboard 31 and the outer corner protection paperboard 32. The entire corner protection paperboard piece 30 comprises three layers of paperboard structures from the inside to the outside. The middle layer is a honeycomb paperboard structure and can provide better buffering effect. When the display screen 200 package falls in a corner or a ridge, the impact force in the corner or the ridge direction is dispersed to each hexagonal structure of the middle honeycomb paperboard 33. The corner strength of the package is greatly improved.

[0048] In one embodiment, referring to Figure 10The outer side of the side paper-plastic wrapping part 10 and the diagonal paper-plastic wrapping part 20 is concavely formed with at least one groove 101, and the paper-plastic folding edge 2 is convexly formed with at least one convex rib 201 on the side facing the side paper-plastic wrapping part 10 and the diagonal paper-plastic wrapping part 20, and the convex rib 201 is embedded in the groove 101 to make the side paper-plastic folding edge 2 and the side paper-plastic wrapping part 10 and the diagonal paper-plastic wrapping part 20 overlap. In a specific implementation, the side paper-plastic wrapping part 10 and the diagonal paper-plastic wrapping part 20 are both cavity structures composed of a surface, and the outer side of the side paper-plastic wrapping part 10 and the diagonal paper-plastic wrapping part 20 is concavely formed with at least one groove 101, which is a groove structure on the side of the paper-plastic wrapping.
