Abstract

This utility model provides a roller cushioning packaging box, including a plate and an elastic telescopic cushioning pad. The plate includes a base plate and a sealing plate. The cushioning pad is fixedly disposed on the inner sides of both ends of the base plate. When the end of the roller abuts against the side wall of the cushioning pad, the cushioning pad and the base plate rotate around the end of the roller to form a receiving cavity for tightly fitting and accommodating the end. The sealing plate is rotatably connected to the base plate and supports and covers the end face of the cushioning pad opposite to the roller. Through the integrated structural design of the base plate and the cushioning pad, the packaging box can be freely and quickly switched between a storage state and a wrapped state, thereby effectively improving packaging efficiency and convenience. At the same time, by setting the cushioning pad as two buffer bodies with their support surfaces perpendicular to each other, effective cushioning support is achieved for the end of the roller in the axial and radial directions, further improving the packaging protection stability of the roller.

Description

Technical Field

[0001] This utility model belongs to the field of cardboard packaging technology, specifically relating to a roller cushioning packaging box. Background Technology

[0002] In modern industrial production and logistics transportation, long and narrow roller products have a large demand for transportation and use in many fields due to their unique shape and wide range of applications. For the packaging protection of rollers, the protection of the roller ends is particularly important.

[0003] The common packaging method currently is to simply wrap the entire roller with packaging material, while only adding a few extra layers of packaging material to the ends. This approach seems to provide enhanced protection for the ends, but it actually has many drawbacks. First, this simple multi-layered wrapping method wastes a lot of packaging material. Due to the lack of targeted design, excessive material often needs to be wrapped around the ends to ensure protection, which not only increases packaging costs but also wastes resources. Second, this packaging method has poor cushioning and protection performance. During transportation, the roller may be subjected to various external impacts and compressions, especially the ends, which are more susceptible to damage. Simple multi-layered wrapping cannot provide sufficient cushioning and cannot effectively absorb and disperse external forces, making the roller ends more prone to wear, deformation, and even breakage.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] like Figure 1-2As shown, this utility model provides a roller cushioning packaging box, which is mainly used to package and protect the electrically powered roller 3 (electric roller). Since the two ends 31 of the roller 3 are the core rotating parts and at least one end is provided with an electric wire 32, and the core parts are easily affected by external forces, bending, deformation or even damage, the packaging and protection of the ends 31 of the roller 3 is particularly important.

[0033] Specifically, the cushioning packaging box includes a board body 1 and an elastically expandable cushioning pad 2. The board body 1 includes a base plate 11 extending radially and a sealing plate 12 extending axially (axial refers to the extension direction of the axis P of the roller 3, and radial refers to the direction perpendicular to the axis P). The two ends of the expandable cushioning pad 2 are respectively fixedly disposed on the inner sides of the two ends of the base plate 11. The cushioning pad 2 and the base plate 11 rotate around the axis P to form a wrapped state. In the wrapped state, the cushioning pad 2 and the base plate 11 both form a radial closed-loop structure. The cushioning pad 2 forms a receiving cavity 13 for tightly fitting and accommodating the end 31. The base plate 11 is disposed on the outer periphery of the cushioning pad 2 to fix and protect the cushioning pad 2.

[0034] When storing, such as Figure 3 As shown in B ( Figure 3 In the diagram, A represents the unfolded state of substrate 11 and B represents the folded state of substrate 11. The substrate 11 is folded along the middle fold line Q, and the cushioning pad 2 is compressed, so that the packaging box is in a flat folded state, which makes it convenient for users to stack and store multiple packaging boxes, and helps to save storage space for packaging materials.

[0035] When using it, such as Figure 4-6 As shown, the user only needs to stretch and unfold the two ends of the substrate 11 or the buffer pad 2 in the radial direction, and then press the end 31 of the roller 3 against the buffer pad 2 from top to bottom. Under the action of gravity of the roller 3 and the shrinkage elasticity of the buffer pad 2, the buffer pad 2 and the substrate 11 rotate around the end 31 of the roller 3 and wrap around it to form the receiving cavity 13. At this time, the end 31 of the roller 3 is firmly wrapped and fixed in the receiving cavity 13, thereby achieving effective cushioning protection of the end 31. At the same time, the whole packaging process is simple and convenient, and no additional cushioning filler is required. It is not only cheaper and more environmentally friendly, but also more efficient.

[0036] It is important to note that, such as Figure 7As shown, with the packaging box wrapping both ends of the roller 3, the roller 3 is supported by the packaging box, and the middle part of the roller 3 is suspended at a certain distance from the ground or tabletop, thereby achieving the purpose of moisture and water protection for the roller 3. At the same time, it also avoids the problem of the middle part of the roller 3 colliding with the ground when it is accidentally dropped during handling and transportation, further improving the transportation safety of the roller 3. Meanwhile, under the protection of the cushioning pad 2 and the base plate 11, the peripheral wall of the end 31 of the roller 3 receives strong cushioning support in both the radial and axial directions, thereby effectively preventing the end 31 of the roller 3 from detaching from or being damaged by the packaging box due to back-and-forth, left-and-right, up-and-down shaking or collision during transportation, further improving the cushioning protection of the roller 3.

[0037] Specifically, such as Figure 7-9 As shown, the end 31 of the roller 3 includes an inner rod 311 and an outer rod 312. The outer rod 312 is disposed outside the inner rod 311 and its diameter is smaller than that of the inner rod 311. Therefore, a step 313 is formed between the inner rod 311 and the outer rod 312. In order to achieve effective support and buffer protection for the end 31, the buffer pad 2 is a retractable honeycomb paper core structure, including a first buffer body 21 and a second buffer body 22 (both the first buffer body 21 and the second buffer body 22 are also the honeycomb paper core structure). The first buffer body 21 surrounds and protects the outer rod 312, while the second buffer body 22 surrounds and protects the inner rod 311.

[0038] Furthermore, since the honeycomb paper cores all have end faces that support cushioning force, these end faces are formed by a number of spaced through holes 23, which can provide favorable cushioning support for the packaged goods. Correspondingly, these end faces are the first support surface 211 of the first buffer body 21 and the second support surface 221 of the second buffer body 22. The first support surface 211 and the second support surface 221 are arranged perpendicular to each other, and the axis P of the roller 3 is arranged perpendicular to the first support surface 211. At this time, the first support surface 211 abuts against the step 313, and the second support surface 221 abuts against the peripheral wall of the inner rod body 311. By abutting the first support surface 211 against the step 313, both ends of the roller 3 are subjected to cushioning force. The axial buffer support force effectively improves the axial buffer protection of the roller 3. At the same time, by correspondingly abutting the second support surface 221 against the peripheral wall of the inner rod 311, the peripheral wall of the inner rod 311 is subjected to radial buffer support force, which effectively improves the radial buffer protection of the end 31 of the roller 3. In other words, through the vertical arrangement of the first support surface 211 and the second support surface 221 and the mutual cooperation of the first buffer body 21 and the second buffer body 22, buffer protection for the roller 3 in the front-back, up-down, and left-right directions is achieved. Similarly, the user can also fill the space between the receiving cavity 13 and the peripheral wall of the end 31 of the roller 3 with adhesive to further strengthen the connection stability between the buffer pad 2 and the roller 3.

[0039] Specifically, such as Figure 3 , 6 As shown, the substrate 11 is used to wrap and support the buffer pad 2 for protection. In practical applications, the wrapping shape of the substrate 11 can be a triangular pyramid, a quadrangular prism, or a polygonal prism. In this embodiment, the substrate 11 is wrapped into a heptagonal prism shape, including a bottom plate 111, a side plate 112, a top plate 113, and a fixing plate 114 arranged symmetrically and rotatably connected in sequence. The top plate 113 includes a connecting plate 1131 and a connecting plate 1132 rotatably connected to each other. The connecting plate 1131 is rotatably connected between the fixing plate 114 and the connecting plate 1132. In the wrapped state, one end face of the two fixing plates 114 is tightly abutting against each other, and the other end face is fixedly bonded to the retractable end of the buffer pad 2. That is to say, the fixing plate 114 and the buffer pad 2 together enclose the receiving cavity 13.

[0040] Furthermore, such as Figure 3 As shown, the fixing plate 114 is provided with a notch 1141 that matches the curve contour of the outer surface of the roller 3 (e.g. Figure 3 (A) The adhesive portion of the buffer pad 2 corresponds to the shape of the fixing plate 114 (e.g., A). Figure 3(B) By setting the notch 1141, the inner wall shape of the receiving cavity 13 is highly fitted with the outer surface of the end 31 of the roller 3, thereby providing sufficient and stable buffer support force for the end 31 of the roller 3.

[0041] Furthermore, such as Figure 7 , 10 As shown in Figure 11, the receiving cavity 13 is provided with a wire-passing hole 131 for allowing the wire 32 to pass through. The first connecting plate 1131 is provided with an outwardly extending extension 1133, and the second connecting plate 1132 is provided with a slot 1134 corresponding to the extension 1133. The slot 1134 communicates with the axial end face of the heptagonal prism. That is to say, during packaging, the wire 32 extends outward from the outer rod 312 and passes through the wire-passing hole 131, the axial end face of the heptagonal prism, and the slot 1134 in sequence, and then extends to the outer periphery of the packaging box or the roller 3, thereby facilitating the user to individually package and protect the wire 32.

[0042] Preferably, in the extension direction along axis P, both connecting plates 1132 are provided with slots 1134, and the two slots 1134 are spaced apart, so that the wire 32 can extend outward from either slot 1134, further improving the convenience of independent packaging of the wire 32.

[0043] Specifically, such as Figure 7 , 10 As shown in Figure 11, the sealing plate 12 is disposed on the substrate 11 at one end away from the roller 3 and is used to close the axial end face of the heptagonal prism (accommodating cavity 13). In the wrapped state, the first buffer body 21 abuts between the sealing plate 12 and the second buffer body 22. At this time, the sealing plate 12 supports and covers the end face of the first buffer body 21 away from the roller 3 and provides effective support for the first buffer body 21, further improving the axial buffer protection stability of the roller 3.

[0044] Meanwhile, the sealing plate 12 can further reinforce the wrapping state of the substrate 11 and the buffer pad 2. Specifically, the sealing plate 12 is provided with a snap-fit ​​plate 121 at the end away from the substrate 11. The snap-fit ​​plate 121 is provided with a first snap-fit ​​groove 122 in the middle. The two fixing plates 114 are provided with a second snap-fit ​​groove 1142 corresponding to the first snap-fit ​​groove 122. The second snap-fit ​​groove 1142 is located on the side close to the top plate 113.

[0045] During packaging, the sealing plate 12 covers the axial end face of the receiving cavity 13, and the snap-fit ​​plate 121 extends to the inner side of the heptagonal prism and is arranged vertically and vertically corresponding to the top plate 113. At this time, the first snap-fit ​​groove 122 is snapped and fixed with the two second snap-fit ​​grooves 1142, so that the two fixing plates 114 are kept in close contact, thereby achieving reinforcement of the packaged state.

[0046] Specifically, since kraft paper has the advantages of high strength and good toughness, while corrugated cardboard has the advantages of higher strength and cushioning, and both are not only low in production cost, but also recyclable and environmentally friendly, in this embodiment, the board 1 is preferably corrugated cardboard, and the material of the cushioning pad 2 is preferably kraft paper.

[0047] The following is a detailed explanation of the working principle of this utility model;

[0048] When the packaging box is in its stored state, the user stretches the two ends of the base plate 11 or the buffer pad 2 in the radial direction to unfold it, and then presses the roller 3 against the buffer pad 2 from top to bottom. At this time, the base plate 11 and the buffer pad 2 rotate around the end 31 of the roller 3 to form a wrapped state, achieving a tight fit and wrapping of the end 31. Then, the sealing plate 12 is folded towards the receiving cavity 13, so that the snap-fit ​​plate 121 on the sealing plate 12 snaps and locks the two fixing plates 114, thereby further reinforcing and supporting the wrapped state.

[0049] The innovation of this utility model lies in the integrated structural design of the base plate and the cushioning pad, which allows the packaging box to switch freely and quickly between the storage state and the wrapped state, thereby effectively improving packaging efficiency and convenience. At the same time, by setting the cushioning pad as two buffer bodies with their support surfaces perpendicular to each other, effective cushioning support is achieved for the roller end in both the axial and radial directions, further improving the packaging protection stability of the roller.
