[0033] 2. Coil Detailed implementation manners

[0034] Although the present utility model can be easily embodied in different forms of embodiments, only some specific embodiments are shown in the drawings and will be described in detail in this specification. At the same time, it can be understood that this specification should be regarded as a demonstration of the principles of the present utility model and is not intended to limit the present utility model to what is described herein.

[0035] Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the present utility model, rather than implying that each embodiment of the present utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to show possible system designs, these features can also be used in other combinations not explicitly described. Therefore, unless otherwise specified, the described combination is not intended to be limiting.

[0036] The present utility model provides a coil recycling packaging box for loading coils.

[0037] Among them, the coil can be a metal foil, which can specifically be a copper foil or an aluminum foil, or it can also be a film coil. The metal foil is wrapped around a reel to form a cylindrical coil.

[0038] Figure 1 The structural schematic diagram of the coil recycling packaging box of this embodiment loading a coil is shown. Refer to Figure 1 , this coil recycling packaging box 1 includes a pallet 11, two support plates 12, an enclosure panel 13 and a top cover 14.

[0039] See Figures 1-3 , the pallet 11 includes a loading surface 111 and a plurality of foot piers 112 protruding from the bottom of the loading surface 111. A plurality of groups of card slots 118 arranged in parallel are provided on the loading surface 111. The two support plates 12 can be selectively clamped on two groups of card slots 118 to movably connect themselves to opposite sides of the pallet 11. In Figure 2In it, four sets of parallel card slots 118 are provided on the tray 11, with two sets provided on each side of the tray 11. During use, the support plate 12 can be selectively installed in the two outer card slots 118 to obtain a relatively long spacing distance, so as to adapt to a longer coil 2. The support plate 12 can also be selectively installed in the two inner card slots 118 to obtain a relatively short spacing distance, so as to adapt to a shorter coil. It is also possible to install one support plate 12 in the outer card slot 118 and the other support plate 12 in the inner card slot 118 to match a coil 2 of medium length. In other embodiments, the number of card slots 118 is not limited to four. As shown in 10, multiple sets of parallel card slots 118 are provided on the tray 11 from one side to the other side in the transverse direction, or multiple sets of parallel card slots 118 can also be provided on the tray 11 from one side to the other side in the longitudinal direction according to needs.

[0040] See Figure 1 , the surrounding plate 13 surrounds the four sides of the tray 11 and is movably connected to the tray 11, and the two support plates 12 are surrounded inside the surrounding plate 13. The top cover 14 is removably covered above the support plate 12 and above the surrounding plate 13.

[0041] A limiting structure is also provided on the top cover 14. The limiting structure cooperates with at least a part of the top of the support plate 12 to keep the support plate 12 in a vertical state. That is, the cooperation of the two support plates 12 with different card slots 118 on the tray 11 adjusts the distance between the two support plates 12 arranged on opposite sides of the tray 11, and further adapts to coils 2 of different sizes. The limiting structure cooperates with the support plate 12 provided at each card slot 118 to keep the support plate 12 stably in a vertical state, ensuring that the support plate 12 stably supports the coil 2, and improving the versatility of the coil recycling packaging box 1.

[0042] After loading the goods, each part of the coil recycling packaging box 1 can be separated from each other, so that the support plate 12 and the surrounding plate 13 can both be folded and placed on the tray 11, realizing stacked transportation during the return journey, so as to reduce the transportation space and lower the transportation cost.

[0043] Figure 2 Fig. shows the structural schematic diagram of the tray in an embodiment. Figure 3 Fig. shows the structural schematic diagram of the tray from another perspective. Combining Figure 2 and Figure 3 , the tray 11 includes a bearing surface 111 and a plurality of feet 112 protruding from the bottom of the bearing surface 111.

[0044] The bearing surface 111 extends in the horizontal direction and is used to bear the coil 2.

[0045] The foot pier 112 is formed by the downward depression of the bearing surface 111 of the tray 11. Among them, a plurality of foot piers 112 are arranged at intervals. A foot pier 112 is provided at each of the four corners of the bearing surface 111. In this embodiment, the number of foot piers 112 is 9, which are distributed in a 3×3 array.

[0046] See Figure 3 , the space between two adjacent columns of foot piers 112 forms a fork-in space for the forklift forks to enter and exit. However, since the widths of forklift forks on the market vary, in order to adapt to the fork-lifting requirements of more forklifts as much as possible, the fork-in space between the foot piers 112 is usually designed to be wider as much as possible. This means that the size of the foot pier 112 will be reduced as much as possible.

[0047] Modern factories are often multi-story buildings with a building structure. Goods are often placed on different floors. In order to easily transport materials to different floors, a roller conveyor is usually set between two floors, and the materials can be easily transported between different floors through the rollers. The coiled material recycling packaging box 1 is no exception, and it also needs to be transported to the target floor through the roller conveyor. However, the small-sized foot pier 112 that is friendly to forklift adaptation is easily stuck in the gap between two adjacent rollers of the roller conveyor, resulting in abnormal operation of the conveyor.

[0048] In order to solve the problems of adapting to more forklifts and meeting the conveying requirements of the roller conveyor at the same time, the bottom side length of the foot pier 112 at the four corner positions of the coiled material recycling packaging box 1 of the present application is greater than the bottom side length of the foot pier 112 at the remaining positions. Therefore, when the tray 11 is placed on the conveyor, since the foot pier 112 at the four corner positions has a larger size, it will not be stuck in the gap between two adjacent rollers of the roller conveyor. And the size of the foot pier 112 at other positions except the foot pier 112 at the four corner positions is smaller, and a larger fork-in space can be formed between two adjacent columns of foot piers 112, so that the tray 11 can adapt to more sizes of AGV forklifts, thereby increasing the versatility of the coiled material recycling packaging box 1. Therefore, the coiled material recycling packaging box 1 can not only be used in cooperation with a variety of AGV forklifts, but also be transported through the roller conveyor.

[0049] See Figure 1 , the surrounding plate 13 is arranged around the tray 11 and is movably connected to the tray 11. The two support plates 12 are surrounded inside the surrounding plate 13.

[0050] Specifically, with reference to Figure 1 and Figure 2 , a circumferential support groove 115 is provided on the periphery of the bearing surface 111 of the tray 11, and the opening of the support groove 115 faces upward. The surrounding plate 13 is clamped in the support groove 115.

[0051] Furthermore, a retaining edge 116 is provided at the periphery of the bearing surface 111. The retaining edge 116 is located outside the support groove 115 and extends upward beyond the bearing surface 111, and is used to limit the position of the surrounding plate 13 located in the support groove 115 to keep it in a vertical state.

[0052] The surrounding plate 13 can be folded into a flat shape, so that it can be stacked on the bearing surface 111 for transportation. Preferably, the surrounding plate 13 includes two detachably connected plate bodies. Each plate body includes a side plate unit and end plate units arranged on both sides of the side plate unit. The end plate units can rotate relative to the side plate unit and fold to fit onto the side plate unit. When the surrounding plate 13 is erected on the tray 11, the side plates extend along the length direction of the tray 11, and the end plates extend along the width direction of the tray 11. In this embodiment, the two plate bodies are connected by a connecting beam. Specifically, the connecting beam is made of aluminum alloy, which improves the strength of the connection and ensures the supporting strength of the surrounding plate 13. In other embodiments, the connecting beam can also be made of plastic. It can be specifically selected according to actual needs.

[0053] The surrounding plate 13 can stand upright in the support groove 115 of the tray 11 to protect the coil 2 located inside the surrounding plate 13. The surrounding plate 13 can also be placed on the tray 11 by folding, which is convenient for the transportation of the surrounding plate 13 when it is empty. Dividing the surrounding plate 13 into two parts is convenient for a single user to operate.

[0054] The surrounding plate 13 can be a honeycomb panel. In this embodiment, the surrounding plate 13 is a PP honeycomb panel. The PP honeycomb panel is made of two relatively thin panels firmly bonded to both sides of a thicker honeycomb core material, also known as a honeycomb sandwich structure. Utilizing the characteristic of the honeycomb panel structure being relatively light in weight, the weight of the entire coil recycling packaging box 1 is reduced.

[0055] The top cover 14 is removably covered above the support plate 12 and above the surrounding plate 13.

[0056] Figure 6 Shows a schematic structural diagram of the top cover 14 in an embodiment. Refer to Figure 6 , the top surface of the top cover 14 is provided with criss-cross grooves 144, and a plurality of grooves 144 communicate with each other. The above grooves 144 are used to accommodate the packing straps. In this embodiment, a plurality of grooves 144 together form a "well" shape.

[0057] See Figure 7 , a surrounding plate groove 141 for the surrounding plate 13 to be inserted is provided around the top cover 14. Through the clamping connection between the top of the surrounding plate 13 and the surrounding plate groove 141, the surrounding plate 13 is further kept in a vertical state.

[0058] Alternatively, the top cover 14 includes a cover plate and a flanging that extends downward and bends along the edge of the cover plate. When the top cover 14 is covered on the surrounding plate 13, the flanging correspondingly fits onto the outer periphery of the surrounding plate 13 to keep the surrounding plate in a vertical state.

[0059] A limiting structure is further provided on the top cover 14. The limiting structure cooperates with at least a part of the top of the support plate 12 to better hold the support plate 12 in a vertical state together with the card slots 118 on the tray 11.

[0060] In one embodiment, the limiting structure includes two strip-shaped bumps 142 formed by protruding downward from the bottom surface of the top cover 14 near both sides (as Figure 7 shown). Correspondingly, two sets of parallel inner and outer card slots 118 are provided at the positions near both sides of the tray 11 (as Figure 2 and Figure 4 shown). When the two support plates 12 are respectively clamped at the two sets of inner card slots 118, the two bumps 142 respectively abut against the outer sides of the two support plates 12, and the inner sides of the support plates 12 are free sides without limitation. When installing the coil material in the coil circulation packaging box 1, although the top cover 14 has no limit on the inner sides of the support plates 12, since the coil material is located between the two support plates 12, the coil material can block the inner sides of the support plates 12 to prevent the support plates 12 from tilting inward. And the outer sides of the support plates 12 cannot tilt outward due to the blocking of the bumps 142, so as to reliably hold the support plates 12 in a vertical state.

[0061] With the limiting structure that limits one side of the support plate 12 by the bump 142, when the top cover 14 is covered on the support plate 12, due to the large distance between the two bumps 142, even if the user cannot see the positions of the bumps 142, the two support plates 12 can be easily aligned between the two bumps 142, so as to smoothly realize the blind insertion alignment of the top cover 14 and improve the assembly efficiency of the top cover 14.

[0062] When the two support plates 12 are respectively clamped at the two sets of outer card slots 118, since the periphery of the support plate 12 is provided with a surrounding plate 13, the surrounding plate 13 is used to block the outer side of the top of the support plate 12 to limit the support plate 12 from tilting outward, so as to ensure that the support plate 12 is kept in a vertical state. Figure 8 Another embodiment of the limiting structure is shown. Refer to Figure 8 , in another embodiment, a plurality of positioning slots 143 for inserting the support plate 12 are formed on the bottom surface of the top cover 14, and the plurality of positioning slots 143 are respectively aligned with a plurality of card slots 118 on the tray 11 (see Figure 2 , Figure 4 or Figure 8 ). That is, positioning slots 143 with openings downward are provided on the bottom surface of the top cover 14, the top of the support plate 12 extends into the positioning slots 143, and the bottom is clamped into the card slots 118, and the support plate 12 is kept in a vertical state through the limiting effects of the tray 11 and the top cover 14.

[0063] Figure 8In the embodiment, multiple sets of positioning grooves 143 are provided on the top cover to clamp the support plate 12, keeping the support plate 12 in a vertical state. Although this structure can also solve the problem of limiting the upper part of the support plate 12, compared with Figure 7 the embodiment, Figure 8 the space for the support plate 12 to be inserted into the positioning groove 143 is relatively narrow, and since the positioning groove 143 is at the bottom of the top cover 14, when the user installs the top cover 14, blind insertion and positioning are often required. To accurately insert the support plate 12 into the positioning groove 143, multiple position adjustments are often needed. Therefore, compared with Figure 7 the embodiment, Figure 8 the positioning difficulty of the limiting structure in it is slightly higher.

[0064] Continue to refer to Figure 3 , the distance between any two adjacent feet 112 is 70 - 500 mm. That is, Figure 3 the distance d in it.

[0065] The heights h of the multiple feet 112 are the same, all being 90 - 150 mm.

[0066] The side length a of the bottom of the foot 112 is 90 - 180 mm. The specific dimensions of the foot 112 can be set according to actual needs.

[0067] Preferably, the side lengths of the feet 112 gradually decrease from top to bottom. That is, the cross-section of each side of the foot 112 is an isosceles trapezoid. Therefore, the distance between two adjacent feet 112 gradually increases from top to bottom, which is more convenient for the AGV forklift to insert.

[0068] As above, multiple sets of parallelly arranged card slots 118 are provided on the bearing surface 111. Preferably, at least three sets of parallelly arranged card slots 118 are provided on the bearing surface 111. Exemplarily, for example, one set of card slots 118 is provided on the first side, and two sets of card slots 118 are provided on the second side. By selectively clamping one of the support plates 12 in the two card slots 118 on the second side, the distance between it and the support plate 12 clamped in the card slots 118 on the first side can be adjusted. Four sets of card slots 118, five sets of card slots 118 or other numbers of card slots 118 can also be provided on the bearing surface 111. The total number of card slots 118 and the number of card slots 118 on the opposite sides can be set according to actual needs.

[0069] The bearing surface 111 forms upwardly open pier slots 113 at the positions of the respective pier feet 112. At a position of the bearing surface 111 adjacent to the pier slot 113, a limiting slot 114 is provided. The limiting slot 114 and the pier slot 113 communicate to form a card slot 118 for the card-connecting portion 121 to be inserted into. Among them, the limiting slots 114 near the pier slots 113 at non-corner positions of the tray 11 constitute the main limiting slots 114, and the limiting slots 114 near the pier slots 113 at the corner positions of the tray 11 constitute the auxiliary limiting slots 114. The length of the main limiting slot 114 is greater than the length of the auxiliary limiting slot 114.

[0070] See Figure 4 and Figure 5 , the portion of the bearing surface 111 between two adjacent limiting slots 114 constitutes a card-connecting convex surface. At a position corresponding to the card-connecting convex surface at the bottom of the support plate 12, a plurality of notches 122 are provided. The portion of the support plate 12 between the notches 122 has a card-connecting portion 121. The card-connecting portion 121 is used to cooperate with the card slot 118 on the tray 11. The cooperation between the notch 122 and the card-connecting convex surface on the tray 11 is realized, so that the support plate 12 and the tray 11 are firmly card-connected.

[0071] In order to reduce the difficulty of aligning the card connection between the support plate 12 and the tray 11, and at the same time reduce the wear rate of the card-connecting portion at the bottom of the support plate 12. The notch at the bottom of the support plate 12 is formed by inward depression of the bottom edge where the support plate 12 contacts the tray 11. The remaining positions of the bottom edge of the support plate 12 except for the notches 122 constitute the card-connecting portion 121. The card-connecting portion 121 is card-connected in the card slot 118 of the tray 11, and the notch 122 is used to hold the card-connecting convex surface of the tray 11. That is, the card connection between the support plate 12 and the tray 11 is realized through the cooperation between the card-connecting portion 121 and the card slot 118 and the cooperation between the notch 122 and the card-connecting convex surface.

[0072] When the support plate 12 is card-connected to the tray 11, at each pier slot 113 of the card slot 118 on the tray 11, the size of the pier slot 113 is relatively large and constitutes a part of the card slot 118. It is very easy to align with the card-connecting portion 121 at the bottom of the support plate 12. Therefore, the support plate 12 can be quickly card-mounted on the tray 11, improving the assembly efficiency. At the same time, the card-connecting convex surface on the tray 11 is actually the bearing surface 111 of the tray 11, avoiding the negative impact that a card-connecting portion structure protruding from the bearing surface 111 may cause scratches to the coil 2 in case the coil 2 falls off the tray 11.

[0073] In addition, since no protruding structure protruding from its bottom edge is provided at the bottom of the support plate 12 to dock with the card slot 118 on the tray 11, but inwardly recessed notches 122 are provided at the bottom edge, the portion between the notches 122 forms a card-connecting portion 121 to dock with the card slot 118, ensuring that the bottom edge of the support plate 12 is not easily bruised or worn due to local outward protrusion.

[0074] Preferably, the length of the clamping portion 121 at the bottom edge of the support plate 12 is greater than the length of the notch 122. On the one hand, the longer clamping portion 121 cooperates with the card slot 118 on the tray 11, so that the clamping portion 121 and the card slot 118 outside the foot pier slot 113 have a longer cooperation distance, ensuring that the clamping portion 121 is firmly clamped on the tray 11. On the other hand, the longer clamping portion 121 can form an anti-wear protection edge at the bottom edge of the support plate 12, avoiding easy bumping and wear caused by local protrusion.

[0075] In this embodiment, the number of the clamping portions 121 is three, and the number of the notches 122 is two. Among them, a notch 122 is provided between any two adjacent clamping portions 121. The three clamping portions 121 are respectively an intermediate clamping portion 121 located between the two notches 122 and an end clamping portion 121 located outside the notch 122. The length of the intermediate clamping portion 121 is greater than the length of the end clamping portion 121, and is adapted to the main limiting groove 114 and the auxiliary limiting groove 114 on the tray 11.

[0076] By increasing the lengths of the intermediate clamping portion 121 and the main limiting groove 114, on the one hand, it facilitates the positioning between the intermediate clamping portion 121 and the main limiting groove 114, improving the positioning efficiency. On the other hand, it also improves the connection strength between the middle part of the support plate 12 and the tray 11, ensuring the stability of the main load-bearing part of the support plate 12 in the middle for carrying the coil 2.

[0077] A support groove 123 for supporting the reel of the coil 2 is provided on the support plate 12. The top of the support groove 123 is open. The support grooves 123 of the two support plates 12 are respectively used to clamp the axial two ends of the reel, realizing the support for the coil 2.

[0078] The number of the support grooves 123 on each support plate 12 can be set according to actual needs. In this embodiment, two support grooves 123 are provided on the support plate 12, and the two support grooves 123 are arranged at intervals in the transverse direction.

[0079] As the main load-bearing structure of the coil recycling packaging box, the support plate 12 has a large loss. Its strength not only affects the load-bearing performance of the coil recycling packaging box 1, but also directly affects the number of recycling times of the coil recycling packaging box 1. In this regard, the support plate 12 includes multiple layers of bamboo or wood plywood. Specifically, it means that the support plate 12 is a multi-layer board formed by gluing bamboo or wood with an adhesive.

[0080] The plywood made of bamboo or wood has excellent strength and load-bearing performance. However, the plywood made of bamboo or wood has a large self-weight, which affects the loading quantity of the transport vehicle. To solve this problem, a plurality of weight-reducing holes 124 are provided on the support plate 12 to reduce the weight of the support plate 12, thereby reducing the weight of the entire coiled material recycling packaging box 1 and effectively increasing the loading quantity during the transportation of the transport vehicle. Among them, the weight-reducing holes 124 avoid the area below the supporting groove 123 and are symmetrically distributed along the vertical center line of the support plate 12. With the above design, not only the weight of the support plate 12 is reduced, but also the uniform stress of the support plate 12 is ensured.

[0081] Preferably, the weight-reducing holes 124 between the two supporting grooves 123 of the support plate 12 include two vertical long holes with the long axis along the vertical direction. At least one horizontal long hole with the long axis in the horizontal direction is arranged below the two vertical long holes. At least one vertical long hole with the long axis in the vertical direction is arranged between each supporting groove 123 and the adjacent side. In this way, on the basis of ensuring that the support plate 12 has excellent strength and load-bearing performance, the self-weight of the bamboo or wood plywood can be reduced to the greatest extent, thereby increasing the loading quantity of the transport vehicle.

[0082] The shape of the weight-reducing hole 124 can be circular, or can also be oval, square with rounded corners at the four corners or other shapes, which are specifically set according to actual needs.

[0083] Continue to refer to Figure 6 , a plurality of receiving grooves 145 recessed downward are provided on the top surface of the top cover 14, and the plurality of receiving grooves 145 are arranged at intervals with the plurality of grooves 144. The plurality of receiving grooves 145 are arranged in one-to-one correspondence with the plurality of feet 112. The receiving groove 145 is used to receive the feet 112 so that the top cover 14 and the feet 112 can be stacked.

[0084] Refer to Figure 9 , the feet 112 of the coiled material recycling packaging box 1 located on the upper layer are received in the receiving grooves 145 of the top cover 14 of the coiled material recycling packaging box 1 located on the lower layer, realizing the stacking of the coiled material recycling packaging boxes 1, improving the stacking stability and reducing the floor area.

[0085] A receiving groove 117 recessed downward for accommodating the position locator is provided on the bearing surface 111. Specifically, in this embodiment, the receiving groove 117 is arranged in the middle area of the bearing surface 111. When the receiving groove 117 accommodates the locator, the top of the locator can be lower than or flush with the bearing surface 111, which can better protect the coiled material 2 located on the bearing surface 111.

[0086] Refer to Figure 10In one of the deformation modes of the support plate 12, the top of the support plate 12 is staggered to form step surfaces of different heights. The step surfaces of different heights are respectively a high step surface 125 and a low step surface 126. The high step surface 125 of the support plate 12 supports and abuts the top cover 14, and the low step surface 126 of the support plate 12 is located below the top cover 14. When the two support plates 12 are relatively placed on the tray 11, the high step surface 125 of one support plate 12 abuts against the low step surface 126 of the other support plate 12.

[0087] The top of the support plate 12 is arranged in a staggered manner, so that the support plate 12 can use its high step surface to support the top cover 14, thereby improving the load-bearing capacity of the coil recycling packaging box 1, so that multiple packaging boxes containing coils can be stacked and transported in the height direction, and the coil packaging tooling located at the bottom can support multiple layers of coil packaging tooling. Figure 11 When the empty coil recycling packaging box 1 is transported back, the two support plates 12 can be put into a flat plate with the high step surface 125 of one support plate 12 butted against the low step surface 126 of the other support plate 12, so that the two support plates 12 are pieced together into a flat plate and laid flat on the bearing surface 111, thereby avoiding the waste of space in the height direction caused by stacking the fixed components up and down, thereby reducing the transportation cost.

[0088] In summary, the coil recycling packaging box 1 has the following advantages:

[0089] 1. The support plates 12 can be selectively mounted in slots at different positions on the pallet 11, so that the positions of the two support plates 12 on opposite sides of the pallet 11 can be adjusted, thereby being able to adapt to coils 2 of different sizes, thereby improving the versatility of the coil recycling packaging box 1.

[0090] 2. The limiting structure on the top cover 14 cooperates with the support plate 12 provided at each slot 118 to keep the support plate 12 stably in a vertical state, ensuring that the support plate 12 stably supports the coil 2. In particular, two raised limiting structures are provided on both sides of the top cover, which can be easily blindly inserted and positioned with the support plate 12. Therefore, the convex blocks will not affect the assembly efficiency of the top cover 14 while limiting the support plate 12.

[0091] 3. The support plate 12 includes multiple layers of bamboo or wood plywood, and combined with the design of the weight-reducing holes 124, the support plate 12 meets the requirements of the supporting strength while reducing its own weight, thereby reducing the weight of the entire coil recycling packaging box 1 and increasing the effective loading quantity of the transport vehicle.

[0092] 4. A notch 122 is provided at the bottom edge of the support plate 12, and the remaining positions of the bottom edge of the support plate 12 except the notch 122 form a clamping portion 121. The length of the clamping portion 121 is greater than the length of the notch 122. When the clamping portion 121 of the support plate 12 is clamped in the card slot on the tray 11, it can be quickly positioned in the card slot, improving the assembly efficiency. At the same time, the design that the length of the clamping portion 121 is greater than the length of the notch 122 can also avoid the phenomenon of difficult positioning and clamping caused by wear of the clamping portion 121.

[0093] 5. The staggered arrangement at the top of the support plate 12 can, on the one hand, improve the load-bearing performance of the top cover, enabling multiple coiled material circulation packaging boxes to be stacked vertically for transportation. Moreover, during return transportation, the two support plates 12 can be placed flat on the tray 11 in such a way that the high step surface 125 of one support plate 12 abuts against the low step surface 126 of the other support plate 12, and can be stacked layer by layer, improving the return transportation efficiency.

Since the present utility model can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims.
