The advantage of this method is that the packaging is quick and convenient, the application of cardboard boxes is extremely mature, and there are no application difficulties. However, in the actual handling and transportation of large items, the twelve right-angled sides of the cardboard boxes of the above shape at the intersection of the faces are prone to deformation after being subjected to force or moisture, and may even be damaged in severe cases, resulting in collision or damage to the items inside the packaging box. In particular, the four longitudinal right-angled sides are prone to bumping during handling and transportation. After being bumped and damaged, the overall right-angled sides are unstable and more prone to bumping and damage. This vicious cycle results in the overall packaging of large items being in tatters after being transported to the target location, and even the items inside are damaged, ultimately resulting in economic losses to the transporter.

[0015] In order to make the technical means, innovative features and functions implemented by the utility model easy to understand, the utility model will be further described below.
[0016] like Figure 1-5 As shown, the technical scheme of the packaging box for rolled non-woven fabric rolls of the utility model comprises a packaging body arranged around the outside of the rolled non-woven fabric roll, a cap-shaped upper packaging cover 2 covering the upper edge of the packaging body, and a lower packaging cover 3 having the same shape as the upper packaging cover 2 and closing the lower edge of the packaging body, wherein the packaging body comprises a plurality of vertical packaging side panels 1.1 contacting and cooperating with a partial area of the outer side of the non-woven fabric roll, and a plurality of transition connecting plates 1.2, wherein the two sides of the transition connecting plate 1.2 are connected to two adjacent packaging side panels 1.1, and a deformation space is reserved between the transition connecting plate 1.2 and the outer side of the non-woven fabric roll for deformation of the transition connecting plate 1.2 and a part of the packaging side panel 1.1, The upper packaging cover 2 and the lower packaging cover 3 are formed by folding a whole packaging mother board after cutting and wrapping it with oily waterproof paper. A plurality of folding areas are provided on the packaging mother board, and the folding areas are symmetrically arranged in pairs. The folding area includes a pair of axially symmetrical S-shaped cutting seams 4 and a folding groove 5 located between the two cutting seams 4. The cutting seams 4 extend from an initial edge of the packaging mother board to the center of the packaging mother board respectively. Two bending points 6 at the same position of the two cutting seams 4 form an inward neck on the packaging mother board. The folding groove 5 is located in the area formed by connecting the two bending points 6 and the ends of the two cutting seams 4.
[0017] Before packaging the rolled non-woven fabric roll, it is necessary to fold the entire pre-cut packaging mother board into the upper packaging cover 2 and the lower packaging cover 3 in advance, that is, first flip up the folding plate formed after the two cutting seams 4 are cut so that it forms a 90° angle with the packaging mother board, and then flip up part of the packaging mother board on both sides of the folding plate to form the vertical brims of the upper packaging cover 2 and the lower packaging cover 3, and put the part of the packaging mother board cut at both ends of the brim into the inner wall of the folding plate and fit it into the inner wall of the folding plate, and finally, the top of the folding plate can be folded back to the inner wall of the folding plate to clamp the two ends of the brim. At the same time, according to actual conditions, the top part of the folding plate can be inserted into the folding groove 5 to realize the limit cooperation in the folding direction of the folding plate. In this way, after all the folding areas are folded, they are wrapped with oily waterproof paper to complete the pre-processing of the upper packaging cover 2 and the lower packaging cover 3 before packaging the rolled non-woven fabric roll.
[0018] In one embodiment of the present invention, Figure 4-5 As shown, the packaging motherboard is a rectangular or square paper foldable hard board, the folding area is located at four right-angle areas of the packaging motherboard, the cutting seams 4 extend from an initial right-angle side of the packaging motherboard to the center of the packaging motherboard, and the cutting seams 4 include a first cutting seam 4.1 extending from the initial right-angle side to the center of the packaging motherboard, a second cutting seam 4.2 whose head end is connected to the end of the first cutting seam 4.1 and extends to the center of the packaging motherboard, and a third cutting seam 4.3 whose head end is connected to the end of the second cutting seam 4.2 and extends to the center of the packaging motherboard According to the actual size of the non-woven fabric roll, if necessary, the lengths of the first cutting seam 4.1, the second cutting seam 4.2 and the third cutting seam 4.3 can be designed to be equal. In order to indicate that the three cutting seams are not strictly equal but do not affect the flexible adjustment according to actual needs during the actual application process, the angle between the first cutting seam 4.1 and the initial right-angle side is in the range of 30°-60°, the second cutting seam 4.2 is perpendicular to the initial right-angle side, and the third cutting seam 4.3 is parallel to the initial right-angle side. In the application process of commonly used rectangular or cube-shaped packaging boxes, the position design of the first cutting seam 4.1, the second cutting seam 4.2, and the third cutting seam 4.3 is convenient for cutting out the overall cutting seam 4 through the cutting equipment, greatly reducing the cutting difficulty and the demand for cutting accuracy, and reducing the production and application cost of the overall packaging box.
[0019] In a preferred embodiment of the present invention, Figure 4-5 As shown, the folding groove 5 is located between the two third cutting seams 4.3, and the extension direction of the folding groove 5 is parallel to or located on the same straight line as the position of the connecting line at the ends of the two third cutting seams 4.3. The design that the folding groove 5 is parallel to or located on the same straight line as the connecting line at the ends of the two third cutting seams 4.3 facilitates the folding plate cut from the packaging mother board to be flipped upwards, is easier to shape, and is not easy to return to its original position.
[0020] In actual application, the cross-section of the transition connecting plate 1.2 is an arc convex outward from the rolled non-woven fabric roll, and the curvature of the transition connecting plate 1.2 is smaller than the curvature of the outer wall of the rolled non-woven fabric roll. The convex transition connecting plate 1.2 can reserve more deformation space between the transition connecting plate 1.2 and the rolled non-woven fabric roll, thereby minimizing the influence of the inevitable deformation of the transition connecting plate 1.2 on the rolled non-woven fabric roll. The curvature of the transition connecting plate 1.2 is smaller than the curvature of the outer wall of the rolled non-woven fabric roll, which makes the transition of the outer wall of the overall packaging box smoother and more integrated. Under the support of the packaging side panel 1.1, the transition connecting plate 1.2 is relatively less likely to deform after being subjected to force and moisture, and the structural strength of the overall packaging box is also partially improved. The overall packaging box is also more sturdy and durable. Under certain conditions, the packaging box can also be recycled for a second time, which reduces the application cost and is relatively more environmentally friendly.
[0021] Although the utility model has been disclosed as above in terms of specific embodiments, it is not intended to limit the utility model. Any technician in this field can make slight changes and modifications without departing from the spirit and scope of the utility model. Therefore, the scope of protection of the utility model should be determined by the scope of the attached claims.
