Description

Technical Field

[0001] This utility model belongs to the field of material transport carrier technology, specifically relating to a general-purpose roll-type product packaging pallet box. Background Technology

[0002] Adhesive film is a thin film material mainly composed of adhesives and a substrate. It is clear and transparent, protecting objects from scratches, damage, dust, and other contaminants. Adhesive film can be used in packaging materials, electronic product protective films, and medical device packaging. Finished adhesive film is packaged in rolls. For off-site transportation of roll adhesive film, current methods generally use pallet packaging or cardboard box packaging. Pallet packaging involves placing the roll on a pallet and securing it to the pallet with strapping and stretch film. Cardboard box packaging provides stronger protection for individual rolls and is suitable for smaller loads. It usually also includes foam or air cushions to reduce impact damage. The protective materials used in pallet and cardboard box packaging cannot be reused, which is not only environmentally unfriendly but also increases packaging costs. The packaging process requires wrapping and filling materials, making it cumbersome and heavily reliant on manual labor. Furthermore, pallet packaging rolls are directly exposed, and cardboard boxes are easily squeezed during transportation. Therefore, neither of these packaging methods can provide strong protection for the roll film, and the roll film is easily damaged during transportation. Utility Model Content

[0003] To address the aforementioned problems and technical needs, this utility model provides a universal roll-type product packaging pallet box. This pallet box does not require filling with protective material, can be recycled, and can stably support and protect the film roll, thereby reducing packaging costs and enhancing the protective effect.

[0004] The technical solution of this utility model is as follows: A general-purpose roll material product packaging box, including a top cover, a bottom support plate, a roll material support plate, a roll material, and a U-shaped side panel. The bottom support plate is rectangular, with symmetrical support slots on both sides and a ring of side panel slots around its four sides. Two roll material support plates are respectively inserted into two support slots. The upper edge of the roll material support plate has multiple support grooves, the bottom of which extends to the middle of the roll material support plate. Fixed mandrels extend from the center of both ends of the roll material and can be correspondingly engaged. Within the support groove, opposing roll material support plates limit and support the roll material through the support groove. When the fixed mandrel is supported within the support groove, the upper side of the roll material is no higher than the upper edge of the roll material support plate. Two opposing U-shaped side panels are respectively inserted into the side panel slots from both sides. The corners of the U-shaped side panels are right angles. The two U-shaped side panels join to form a rectangular space, enclosing the roll material support plate and the roll material. The top cover is placed on the upper edge of the two U-shaped side panels, and the top cover limits both the U-shaped side panels and the roll material support plate. In this solution, the roll material support plates provide support and limit the roll material, allowing the roll material to remain suspended within the box. During the box's transport, the roll material does not require cushioning materials such as foam, and there is no squeezing or collision between the roll material and the box. This saves packaging costs and provides better protection for the roll material.

[0005] Furthermore, the support slots include a left slot, a middle slot, and a right slot spaced along a straight line. The areas between the left and middle slots, and between the right and middle slots, are flat surfaces flush with the base plate. Two symmetrical positioning grooves are provided on both sides of the bottom edge of the roll material support plate. The roll material support plate is inserted into the support slots, with the two sides and the middle portion of the bottom edge of the roll material support plate respectively engaging with the left, right, and middle slots. The two positioning grooves are respectively embedded between the middle slot and the left and right slots. By configuring the support slots and the roll material support plate as a convex-concave mating engagement, the roll material support plate can be positioned, preventing it from sliding along its length. After assembly, the roll material support plate and the base plate maintain a relatively fixed position.

[0006] Furthermore, the bottom support plate is symmetrically provided with multiple sets of support slots on both sides, and the support slots are parallel to each other. By inserting the roll material support plate into different support slots, it can accommodate roll materials of different lengths.

[0007] Furthermore, the bottom edge of the top cover is provided with a top groove, and the upper edges of the two U-shaped panels in the enclosed state are embedded in the top groove. A limiting protrusion is provided parallel to the inner side of the top groove, limiting the upper edge of the roll material support plate. The limiting protrusion and the support groove respectively limit the upper and lower edges of the roll material support plate, keeping the roll material support plate stable within the box and improving the stability of the support.

[0008] Furthermore, the opposite ends of the two U-shaped panels are connected by an H-shaped edge strip. The H-shaped edge strip is the same height as the U-shaped panel, and slots with the same thickness as the U-shaped panel are provided on both sides of the H-shaped edge strip. The opposite ends of the two U-shaped panels are respectively inserted into the slots on both sides of the same H-shaped edge strip.

[0009] Furthermore, the base plate has a built-in grid-shaped steel frame. The grid-shaped steel frame can improve the rigidity of the base plate, increase its load-bearing capacity, and prevent the base plate from deforming.

[0010] Furthermore, the bottom support plate has protruding support feet at its corners and center, and the upper surface of the top cover has support foot positioning grooves. When multiple pallet boxes are stacked, the support feet of the upper bottom support plate fall into the corresponding support foot positioning grooves of the lower top cover. The pallet boxes can be stacked on top of each other, saving transportation space and increasing the carrying capacity.

[0011] Furthermore, a packer is provided at each of the four edges of the top cover and the bottom support plate, which can lock the top cover, the bottom support plate and the U-shaped panel together.

[0012] The beneficial effects of this utility model are as follows: 1) Two opposing roll support plates support the roll material inside the box, keeping it suspended. The roll material's perimeter will not collide or be squeezed with the top cover, side walls, and bottom support plate of the box. The box does not need additional protective materials such as foam to achieve a good protective effect, reducing packaging costs; 2) The top cover, roll support plates, U-shaped side panels, and bottom support plate of the box can all be freely disassembled. After disassembly, stacking them can save storage space and reduce recycling costs. All parts of the box can be recycled, making it more environmentally friendly than cardboard box packaging; 3) Multiple support slots are provided to improve the versatility of the box and meet the transportation requirements of roll materials of different lengths.
