[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Please refer to Figures 1 to 8 To address the technical problems described in the background section, embodiments of this utility model provide a core tray, comprising: a tray body 1, on which a bearing area 11 for holding cores is provided; a support structure 2, on which the tray body 1 is mounted, and the support structure 2 supports at least a portion of the tray body 1; and a fixing structure 3, which is connected to both the tray body 1 and the support structure 2 to fix the tray body 1 to the support structure 2; wherein the fixing structure 3 is a strip structure extending along the edge of the tray body 1, and there are multiple fixing structures 3 arranged sequentially along the edge of the tray body 1.

[0034] This embodiment of the invention employs a modular design for the core tray, comprising a tray body 1, a support structure 2, and a fixing structure 3. The support structure 2 supports at least a portion of the tray body 1, and the fixing structure 3 is a strip-shaped structure extending along the edge of the tray body 1. Multiple fixing structures 3 secure the edge of the tray body 1, ensuring its reliable installation on the support structure 2. This structural design allows the tray body 1 to be reliably mounted on the support structure 2, thereby enhancing the structural strength of the tray body 1, reducing deformation, and increasing its load-bearing capacity. This enables it to withstand heavier loads and better meet the requirements of long-term stress and subsequent cell baking. Thus, the structural strength of the core tray can be significantly improved at a relatively low cost, better meeting usage requirements and solving the technical problem of low structural strength in related technologies, demonstrating high practical application value.

[0035] In this embodiment, the pallet body 1 and the support structure 2 are detachably connected (e.g., by snap-fit, fastener connection, etc., as long as the connection and disassembly between the two can be achieved). By designing the structure between the two as detachable, the pallet body 1 can be easily disassembled and replaced when it is damaged, making the maintenance of the core tray more convenient.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, in this embodiment, the bearing area 11 is divided into several units, each unit corresponding to a single core during use. The surface of each unit that mates with the core is the bearing surface, and at least part of the bearing surface has a shape that matches the shape of the core. When the core is placed in the bearing area 11, the bearing surface mates with the outer surface of the core. This makes the bearing of the core by the tray body 1 more stable and reliable.

[0037] In this embodiment, the core tray includes multiple tray bodies 1, each with a different shape and / or size of its bearing surface, allowing for the support of cores of different shapes and / or sizes. The tray bodies 1 are detachably connected to the support structure 2. By disassembling the tray bodies 1 from the support structure 2, different tray bodies 1 can be easily replaced, making it suitable for supporting cores of different sizes and / or shapes. Compared to trays in related technologies that can only support one type of core, this effectively improves the versatility of the core tray.

[0038] As one of the preferred embodiments, the support structure 2 is a frame structure, which is located at the bottom of the pallet body 1 to support the pallet body 1. In this way, not only is the weight of the support structure 2 smaller, but its supporting effect can also be guaranteed.

[0039] In a preferred embodiment, the support structure 2 is a ring frame. When the pallet body 1 is installed onto the ring frame, the ring frame contacts the edge of the pallet body 1 to support the edge of the pallet body 1. This provides a more uniform support force to the pallet body 1 and improves the support effect of the pallet body 1.

[0040] In this embodiment, at least a portion of the pallet body 1 is located between the support structure 2 and the fixing structure 3, so that the pallet body 1 is pressed and fixed to the support structure 2 by the fixing structure 3. In this way, not only is it convenient to install and disassemble the pallet body 1, but the fixing force is also more distributed and uniform, the fixing effect is better, and the risk of tearing at the fixing position of the pallet body 1 can be reduced.

[0041] The fixing structure 3 is provided with a plurality of first protrusions 31, which are spaced apart along the length of the strip structure. The supporting structure 2 is provided with a plurality of first mating holes 24, and the plurality of first protrusions 31 are inserted into the plurality of first mating holes 24 in a corresponding manner. The supporting structure 2 is provided with a plurality of second protrusions 23, which are spaced apart along the length of the strip structure. The fixing structure 3 is provided with a plurality of second mating holes 32, and the plurality of second protrusions 23 are inserted into the plurality of second mating holes 32 in a corresponding manner. The tray body 1 is provided with a plurality of first through holes 13, and the plurality of first protrusions 31 are inserted into the plurality of first through holes 13 in a corresponding manner. The tray body 1 is provided with a plurality of second through holes 14, and the plurality of second protrusions 23 are inserted into the plurality of second through holes 14 in a corresponding manner.

[0042] Please refer to Figure 3 , Figure 7 and Figure 8 , Figure 3 This is a schematic diagram of the support structure of an embodiment of the core tray of this utility model from a first-view perspective. Figure 7 This is a schematic diagram illustrating an embodiment of the core tray of this utility model in a stacked state of multiple trays. Figure 8 for Figure 7 A magnified structural diagram of a local area in the middle. Figure 7In this embodiment, the first tray 10 is stacked on top of the second tray 20. The support structure 2 is provided with a positioning part 21. When multiple core trays are stacked, adjacent core trays engage with each other through the positioning part 21 to position them. By designing the positioning part 21, when multiple core trays are stacked, two core trays engage with each other through the positioning part 21. Specifically, the positioning part 21 of one core tray can engage with any position of another core tray, for example, the positioning part 21 of one core tray can be inserted into the positioning part 21 of another core tray, thereby achieving positioning and ensuring a more accurate engagement between the two core trays, thus ensuring stacking stability.

[0043] The support structure 2 is provided with a support part 22, which supports adjacent core trays when multiple core trays are stacked. By designing the support part 22, adjacent core trays can be supported (e.g., the support structure 2 of adjacent trays, or the tray body 1 of adjacent trays), resulting in more stable stacking and stronger compressive strength between adjacent core trays, thus allowing for more layers to be stacked. Actual verification shows that trays in related technologies typically have no more than 15 stacked layers. However, the core tray of this invention, using the above-described structure, can have up to 20 stacked layers. In a preferred embodiment, there are multiple positioning parts 21, which are sequentially spaced along the circumference of the support structure 2. In this embodiment, there are multiple positioning parts 21, which are sequentially and correspondingly positioned at multiple corners of the support structure 2. There are also multiple support parts 22, which are sequentially spaced along the circumference of the support structure 2, thereby improving its support effect.

[0044] like Figure 5 As shown in this embodiment, the pallet body 1 is provided with multiple clearance openings 12, and the positions of the multiple clearance openings 12 correspond one-to-one with the positions of multiple positioning parts 21. Each positioning part 21 is inserted into the corresponding clearance opening 12. In this way, not only can the pallet body 1 avoid interference with the positioning parts 21, but the positioning parts 21 can also be used to position the pallet body 1, thereby improving the stability of the installation of the pallet body 1.

[0045] As some preferred embodiments, the roll core tray satisfies at least one of the following: the tray body 1 is manufactured using a vacuum forming process, thereby reducing its manufacturing cost and better fitting with the roll core for load-bearing. Even with the tray body 1 manufactured using a vacuum forming process, the roll core tray, in conjunction with the support structure 2 and the fixing structure 3, still possesses high structural strength to meet usage requirements.

[0046] The function of the support structure 2 is to increase the overall structural strength of the core tray. Therefore, in a preferred embodiment, it is designed to have higher strength than the tray body 1. For example, when the core tray holds cores, the thickness of the support structure 2 is greater than the material thickness of the tray body 1 along the direction of force on the core tray. Figure 2 As shown, when the tray body 1 holds the core roll, its stress direction is downward. Along the vertical direction, the material thickness of the tray body 1 is relatively thin, while the thickness of the support structure 2 is significantly greater along the vertical direction. Through the supporting effect of the support structure 2, the pressure resistance of the tray body 1 can be significantly improved, increasing the load-bearing capacity of the core roll tray. For example, when the core roll tray holds the core roll, along the stress direction of the core roll tray, the deformation resistance of the support structure 2 is greater than that of the tray body 1.

[0047] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0048] The core tray of this utility model embodiment includes: a tray body 1, on which a bearing area 11 for holding cores is provided; a support structure 2, on which the tray body 1 is installed, and the support structure 2 supports at least a portion of the tray body 1; and a fixing structure 3, which is connected to both the tray body 1 and the support structure 2 to fix the tray body 1 to the support structure 2. The fixing structure 3 is a strip-shaped structure extending along the edge of the tray body 1, and there are multiple fixing structures 3 arranged sequentially along the edge of the tray body 1. The core tray of this utility model embodiment adopts a modular design, comprising a tray body 1, a support structure 2, and a fixing structure 3. The support structure 2 supports at least a portion of the tray body 1, and the fixing structure 3, being a strip-shaped structure extending along the edge of the tray body 1, fixes the edge of the tray body 1 to ensure reliable installation on the support structure 2. This structural design allows the tray body 1 to be reliably mounted on the support structure 2. The support structure 2 enhances the structural strength of the tray body 1, reduces deformation, and increases its load-bearing capacity, enabling it to withstand heavier loads and better meet the requirements of long-term stress and subsequent cell baking. This significantly improves the structural strength of the core tray at a relatively low cost, better meeting usage requirements and solving the technical problem of low structural strength in core trays in related technologies. It has high practical application value.
