Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile wheel hub packaging, in particular to a tray, a partition and a wheel hub packaging material. Background Art
[0002] During the transportation of wheel hubs, it is often necessary to stack multiple wheel hubs together and place them together in a container for collective transportation. In order to prevent collisions between wheel hubs during transportation, it is often necessary to wrap the outside of the wheel hub with packaging materials, such as foam pads, bubble wrap and other materials to protect the wheel hub. While fixing the wheel hub, avoid collisions between adjacent wheel hubs due to shaking during transportation, thereby causing damage to the wheel hub. In order to make full use of all the space in the container, it is often necessary to stack the wheel hubs to make full use of the three-dimensional space in the container. At the same time, wheel hubs can be classified into different sizes according to their different sizes, and wheel hubs of different sizes cannot be directly stacked due to their different diameters.
[0003] At present, a packaging material is used to fix the wheel hub, and the packaging material includes a middle liner and a pallet. The middle liner is provided with a fixing position for fixing the wheel hub, and different sizes of wheel hubs will have different middle liners corresponding to it. During the transportation of the wheel hub, there will be a pallet corresponding to the middle liner at the bottom of the packaging material. Since the size and position of the fixing position of the wheel hub of different middle liners will be different, different pallets are required. The demand for pallets during use is far less than that of middle liners, but the sizes of wheel hubs are numerous, so corresponding pallets need to be set for wheel hubs of different sizes, that is, multiple pallet molds must be produced, which increases production costs. In addition, pallets of multiple sizes often cause the misuse of pallets and middle liners, which affects the packaging and transportation efficiency of the wheel hub. Utility Model Content
[0004] In order to make up for the deficiency that different middle liners in the prior art need to match different pallets, thus multiple pallet molds need to be opened, while the utilization rate of the pallets is low, resulting in an increase in the cost of opening the molds, the utility model provides a pallet, a partition and a hub packaging material.

[0048] Example 1
[0049] like Figure 1 , Figure 2 As shown, the utility model provides a pallet, the pallet has a first upper surface and a first lower surface opposite to the first upper surface, the first upper surface is provided with a positioning structure, the positioning structure is used to be adapted and installed with the partitions of various hub packaging materials, and the positioning structure includes: at least one positioning space 1, which is provided on the first upper surface of the pallet. Among them, at least one positioning space 1 is used to position any partition cover when it is provided on the first upper surface of the pallet.
[0050] It is not difficult to infer from the above content that in the process of using the partition, the partition needs to be fixed on the pallet so that the pallet can be supported. The positioning structure set on the first upper surface of the pallet needs to be adapted to the bottom of the partition, and the partition is positioned by the positioning structure so that the partition is fixed, and then the hub can be set on the partition. At this time, since the partition is positioned and will not slide relative to the pallet, the hub can also remain stationary after being placed on the partition, which is convenient for the overall transportation of the hub placed on the partition. At the same time, the size of the hub is different. In order to meet the placement of hubs of different sizes, a partition corresponding to the size of the hub will be made. A hub storage position 5 is set on the second upper surface of the partition. The hub storage position 5 is a disc protruding upward, and the diameter of the disc is the same as the inner diameter of the hub. When the hub is set in the hub storage position 5, the inner diameter of the hub matches the diameter of the hub storage position 5, so that the hub can be set outside the disc and limited by the disc. Therefore, in order to fix hubs of different sizes, it is necessary to select a partition corresponding to the size of the hub. Different hub storage positions 5 have different diameters of discs, so in order to keep the total area of the partition unchanged, the layout of the hub storage positions 5 on the partition is also different. In this embodiment, the positioning space 1 of the tray can match different partitions, and the partition is positioned with the tray through the positioning space 1 of the tray to ensure that there is no relative offset after the partition is placed. As a result, different partitions for placing hubs of different sizes can use the same pallet as a supporting base, that is, the handling of hubs of different sizes is completed, and the adaptability of the pallet is improved. At the same time, the development of the production mold of the pallet is reduced, and due to the improvement of the adaptability of the pallet, there is no need to worry about the mismatch between the selected pallet and the partition during the packaging process of the hub. The work efficiency in the hub packaging process is improved, and the error problem in the packaging process is also avoided.
[0051] like Figure 1 , Figure 2 As shown, the positioning space 1 includes: an external positioning space 11 and an internal positioning space 12. The external positioning space 11 is arranged at the edge of the first upper surface of the tray, and the external positioning space 11 cooperates with the external limiting protrusion 31 of the partition to position the partition. The internal positioning space 12 is arranged in the middle part of the first upper surface of the tray, and the internal positioning space 12 cooperates with the internal limiting protrusion 32 of the partition to position the partition.
[0052] It is not difficult to infer from the above content that the external positioning space 11 on the pallet can be matched and positioned with the surrounding of the partition. When the surrounding of the partition is matched and positioned with the pallet, the center of the partition and the center of the pallet are located on the same straight line, and the surrounding of the pallet can evenly support the partition. When the wheel hub is placed on the partition, the self-weight of the wheel hub will act on the partition. When the center of the partition and the center of the pallet are located on the same vertical line, and the surrounding of the partition is positioned by the external positioning space 11 of the pallet. At this time, the force of the wheel hub on the partition can be evenly transmitted to the pallet. In addition, the pallet can be subjected to uniform external force from the partition, avoiding uneven force on a certain part of the pallet due to the positioning deviation between the pallet and the partition, thereby causing damage to the pallet or the partition. Furthermore, multiple layers of hubs will be stacked during transportation, so it is necessary to set partitions between each layer of hubs. Because the centers of the pallet and the partition are on the same vertical line, the center of gravity of the stacked wheel hub is also located at the center of the pallet and the partition, so the stacked wheel hub will not tip over due to the difference in the center of gravity, which further ensures the safety of the wheel hub transportation.
[0053] The internal positioning space 12 on the pallet can be positioned and matched with the middle part of the partition. Since the material used in the middle part of the pallet is more than the material around the pallet, the size of the internal positioning space 12 is larger than the size of the external positioning space 11. This allows more matching parts between the partition and the pallet, thereby improving the stability of the matching between the pallet and the partition. The matching between the partition and the pallet is ensured, and the stability of the wheel hub during transportation is also ensured.
[0054] In addition, if Figure 1 , Figure 2The positioning structure shown in the embodiment of the utility model also includes: at least one positioning protrusion 2, which is arranged on the first upper surface of the pallet. Wherein, at least one positioning protrusion 2 is used to position the partition when any partition cover is arranged on the first upper surface of the pallet. The positioning protrusion 2 includes: an external positioning protrusion 21 and an internal positioning protrusion 22. The external positioning protrusion 21 is arranged at the edge of the first upper surface of the pallet, and an external positioning space 11 is formed on the external positioning protrusion 21. The internal positioning protrusion 22 is arranged in the middle part of the first upper surface of the pallet, and an internal positioning space 12 is formed on the internal positioning protrusion 22. Wherein, at least part of the external limiting protrusion 31 cooperates with the external positioning protrusion 21 from the side of the external positioning protrusion 21 away from the center of the pallet.
[0055] It is not difficult to infer from the above content that in the process of matching the partition and the tray, the limiting protrusion 3 set on the second lower surface of the partition will extend into the positioning space 1 set on the first upper surface of the tray. The positioning protrusion 2 will have depressions of different shapes, and the positioning space 1 is formed by the depression. Therefore, when the limiting protrusion 3 and the positioning space 1 cooperate with each other, the side walls of some limiting protrusions 3 will be mutually attached and mutually limited with the side walls of some positioning protrusions 2 to position the partition on the tray. And from the above we can get that in order to make the partition better positioned on the tray. It is necessary to position the partition around the external positioning space 11, and at the same time use the internal positioning space 12 to position the middle part of the partition to ensure the positioning effect between the partition and the tray. The external positioning protrusion 21 and the internal positioning protrusion 22 can meet the requirements of forming the external positioning space 11 and the internal positioning space 12 on the tray. And in some embodiments, in order to improve the strength of the positioning protrusion 2, the external positioning protrusion 21 and the internal positioning protrusion 22 can be integrally formed with the tray body. This ensures the strength of the positioning protrusion 2, and also ensures the overall strength of the pallet. The external limiting protrusion 31 of the partition needs to cooperate with the external positioning protrusion 21 from the side of the external positioning protrusion 21 away from the center of the pallet. At this time, when the partition is positioned on the pallet, the external limiting protrusion 31 of the partition will surround and cooperate with the outer circle of the external positioning protrusion 21, so that the partition forms a covering effect like a lid. In this state, the external limiting protrusion 31 and the external positioning protrusion 21 will limit each other in the horizontal direction. After positioning, the partition will not slide relative to the pallet horizontally, further improving the stability after positioning.
[0056] In addition, if Figure 1 , Figure 2 As shown in the embodiment of the utility model, the pallet further comprises a plurality of legs 6, which are recessed from the first upper surface of the pallet toward the first lower surface to form a hollow shell 61. At least one positioning space 1 partially overlaps with the hollow shell 61.
[0057] It is not difficult to infer from the above that the support leg 6 and the pallet are formed in one piece. The connection between the support leg 6 and the pallet body is eliminated, thereby improving the overall strength of the pallet. In addition, the hollow foot support reduces the overall mass of the foot support, thereby reducing the overall mass of the pallet, making it easier to carry the pallet while ensuring the wheel hub. Furthermore, part of the positioning space 1 partially overlaps with the hollow shell 61 of the foot support, that is, the positioning space 1 utilizes part of the space of the hollow shell 61. When the limiting protrusion 3 of the partition cooperates with the positioning space 1 of the pallet, part of the limiting protrusion 3 will extend into the hollow shell 61. By reusing space, the number of additional positioning spaces 1 opened on the pallet is reduced, and the positioning between the partition and the pallet is met while ensuring the structural rigidity of the pallet.
[0058] Example 2
[0059] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, an embodiment of the utility model further provides a partition, the partition having a second upper surface and a second lower surface opposite to the second upper surface. A limiting structure is provided on the second lower surface, and the limiting structure is used to be adapted and installed with the above-mentioned tray. The limiting structure includes: at least one limiting protrusion 3, which is provided on the second lower surface of the partition. Among them, when any limiting protrusion 3 is used for the partition cover to be provided on the first upper surface of the tray, it is embedded in at least one positioning groove of the tray, so that the partition is positioned on the first upper surface of the tray.
[0060] It is not difficult to infer from the above content that in the process of packaging the wheel hub, the partition needs to be set on the pallet, and then the wheel hub is placed on the wheel hub placement position on the partition. Therefore, the partition and the pallet need to cooperate first to position the partition to prevent the partition from moving. When positioning the partition, the limiting protrusion 3 located on the second lower surface of the partition can be inserted into the positioning space 1 of the pallet in Example 1. Since there is a cooperation between the limiting protrusion 3 and the positioning space 1, the limiting protrusion 3 can be restricted by the positioning space 1, which limits the freedom of the limiting protrusion 3 and the freedom of the partition, so that the partition is positioned on the pallet. When the partition is stable, the wheel hub can be placed better. In order to be able to set wheel hubs of different sizes, partitions with different wheel hub placement positions will be prepared to correspond to the size of the wheel hub. Therefore, through Figure 3 and Figure 5We know that the hub placement positions of the partitions for placing wheels of different sizes are different in size, and the arrangement of the hub placement positions is also different. Therefore, the distribution of the limiting protrusions 3 of the partitions of different sizes is also different. In the process of positioning the partitions and the tray, the limiting protrusions 3 of different partitions can be inserted into different positioning spaces 1 located on the first upper surface of the tray. When positioning, not all positioning spaces 1 will extend into the limiting protrusions 3 at the same time. More positioning spaces 1 are reserved for matching with other different partitions, which improves the adaptability between the partitions and the push trays, and is more conducive to improving the packaging efficiency during the wheel packaging process.
[0061] And refer to Figure 4 , Figure 6 As shown, in some embodiments of the utility model, the limiting protrusion 3 includes: an external limiting protrusion 31 and an internal limiting protrusion 32. The external limiting protrusion 31 is arranged at the edge of the second lower surface of the partition, and the external limiting protrusion 31 cooperates with the external positioning space 11 of the tray to position the partition. The internal limiting protrusion 32 is arranged at the edge of the second lower surface of the partition, and the internal limiting protrusion 32 cooperates with the internal positioning space 12 of the tray to position the partition.
[0062] It is not difficult to infer from the above content that the external limiting protrusion 31 can achieve accurate positioning between the periphery of the partition and the pallet. When the periphery of the partition and the periphery of the pallet are accurately positioned, their centers are located on the same numerical line, which avoids the problem of the center of gravity of the stacked wheel hubs being misaligned after the wheel hubs are packaged, causing problems such as tipping. The internal limiting protrusion 32 can match the internal positioning space 12 of the pallet, thereby further ensuring the positioning effect between the partition and the pallet.
[0063] For further reference Figure 4 , Figure 6 As shown, the limiting structure also includes: at least one limiting groove 4, which is arranged on the second lower surface of the partition. Among them, when any limiting groove 4 is used for the partition cover to be arranged on the first upper surface of the pallet, it is embedded by at least one positioning protrusion 2 on the pallet, so that the partition is positioned on the first upper surface of the pallet. The limiting groove 4 includes: an external limiting groove 41 and an internal limiting groove 42. The external limiting groove 41 is formed on the external limiting protrusion 31, which is used to cooperate with the external positioning protrusion 21 of the pallet to position the partition. The internal limiting groove 42 is formed on the internal limiting protrusion 32, which is used to cooperate with the internal positioning protrusion 22 of the pallet to position the partition.
[0064] It is not difficult to infer from the above content that the internal limiting protrusion 32 and the external limiting protrusion 31 are respectively used to cooperate with the surrounding and the middle part of the partition when the partition is positioned. And the internal limiting protrusion 32 and the external limiting protrusion 31 need to extend into the external positioning space 11 and the internal positioning space 12 respectively. Since the external positioning space 1 and the internal positioning space 12 are respectively set on the external positioning protrusion 21 and the internal positioning protrusion 22, the external positioning protrusion 21 and the internal positioning protrusion 22 will also move toward the direction of the partition during the cooperation between the internal limiting protrusion 32 and the external limiting protrusion 31. The external limiting groove 41 and the internal limiting groove 42 can make the external positioning protrusion 21 and the internal positioning protrusion 22 extend, which has the effect of avoiding the external positioning protrusion 21 and the internal positioning protrusion 22. To ensure the fit between the partition and the pallet, the fit between the external limit groove 41 and the external positioning protrusion 21, as well as the fit between the internal limit groove 42 and the internal positioning protrusion 22, can further strengthen the fit between the partition and the pallet, thereby ensuring the positioning effect of the partition.
[0065] Example 3
[0066] Finally, an embodiment of the utility model further provides a hub packaging material, comprising: the above-mentioned pallet and at least one of the above-mentioned partitions, wherein any one of the partitions is used to cover the first upper surface of the pallet, so that the pallet supports and positions the partition.
[0067] It can be concluded from the above content that when the wheel hub packaging material adopts the above-mentioned pallet and partition, the partition can not only be accurately positioned on the pallet, but also because the pallet can match various sizes of partitions, the packaging difficulty of the wheel hub is also reduced. For example, when two wheels of different sizes need to be stacked and transported, first place the first pallet on the bottom layer, position the first size of partition on the bottom layer of the pallet, and then place the wheel hub on the positioned partition. After the first size of the wheel hub is placed, cover the wheel hub with a layer of partition after placement, and place the partition on the covered partition. After the partition is placed, place another pallet on the partition, and position another size of partition on the placed pallet. At this time, the wheel hub of the corresponding size can be placed on the new partition. Since the pallet can match different partitions, there is no need to worry about taking the two pallets by mistake when facing this situation. While improving work efficiency, it reduces the probability of errors in the packaging process. In addition, the utilization rate of pallets is less than that of partitions, so in the production process of packaging materials, the number of partitions is often more than that of pallets. Therefore, the utilization rate of pallet molds is lower than that of partition molds. When the pallet can be matched with a variety of partitions, the utilization rate of the pallet mold is improved, which fully reduces the production cost.
