Description

Technical Field

[0001] This application relates to the field of pallets, and more particularly to a molded pallet and a transport system. Background Technology

[0002] A pallet is a structure used for containerizing, stacking, handling, and transporting goods, primarily for carrying them. Pallets are widely used in logistics, warehousing, transportation, and packaging. To reduce carbon emissions, protect the environment, and lower costs, replacing solid wood pallets with molded pallets made from recycled materials such as wood shavings and bamboo is becoming a development trend.

[0003] Currently, the pallets used are nine-corner molded pallets, which are formed in one piece through molding. The nine corner blocks in the nine-corner molded pallet are used to provide support, and the openings of the corner blocks face upwards.

[0004] However, when using this type of pallet, because the openings of the corner blocks face upwards, the surface of the pallet that supports the items has nine large-area grooves or pits, which makes the bottom of the supported items unevenly stressed and prone to breakage.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0040] The most commonly used molded pallets on the market are nine-corner molded pallets, which are formed in one piece through molding. The nine corner supports of the nine-corner molded pallet provide support; each corner support is hollow, with one end open and the other closed. When using a nine-corner molded pallet to carry items, the open ends of the corner supports face the support panel, while the closed ends face away from the support panel. This results in two problems: First, the open ends of the nine corner supports create nine large grooves or pits on the support panel, causing uneven stress on the bottom of the items supported by the pallet, making them prone to breakage. Second, when the nine-corner molded pallet is placed on a logistics transport line, the mismatch between the pallet and the line can cause the closed ends of the corner supports to get stuck in the gap between adjacent rollers, preventing the entire pallet of items from being transported or causing it to shake violently. Based on this, this application proposes a molded pallet that can provide uniform support for the carried items and is suitable for logistics transportation lines. The technical solution of the molded pallet designed in this application is described as follows:

[0041] Figure 1 This is a schematic diagram of a three-dimensional structure of a molded tray provided in an embodiment of this application. Please refer to [link / reference]. Figure 1 This application provides a molded tray, including a molded support 110 and a molded panel 120.

[0042] The molded bracket 110 includes: an integrally formed base plate 111 and multiple support blocks 112. The base plate 111 has multiple openings 113 corresponding to the multiple support blocks 112. One end of the support block 112 near the base plate 111 is fixedly connected to the base plate 111 at the corresponding opening 113, and the support block 112 has an inner cavity communicating with the corresponding opening 113.

[0043] The molded panel 120 includes: adjacent main support parts and multiple auxiliary support parts. The multiple auxiliary support parts are connected to the ends of multiple support blocks 112 opposite to the bottom plate 111. The side of the main support part opposite to the molded bracket 110 is flush with the side of the auxiliary support part opposite to the molded bracket 110.

[0044] The main support and at least part of the auxiliary support are located on the side opposite to the molded bracket 110 and are used to support the items.

[0045] By designing the support pier 112, which provides support, on the base plate 111 of the molding bracket 110, and setting the opening of the support pier 112 facing the base plate 111, the support pier 112 in the molding bracket 110 is connected to the auxiliary support part in the molding panel 120. The side of the main support part away from the molding bracket 110 is flush with the side of the auxiliary support part away from the molding bracket 110. In this way, at least the surface of the molding panel 120 away from the molding bracket 110 is a relatively flat surface, which facilitates the provision of uniform support force to the items carried on it, and effectively avoids the damage of items carried on the molding tray due to uneven force.

[0046] When transporting molded pallets on a logistics transportation line, the bottom plate 111 contacts multiple rollers on the logistics transportation line, which enables the molded pallets to be transported smoothly, making the molded pallets compatible with the logistics transportation line.

[0047] For example, the items carried on the molded pallet may be foam boxes containing liquid crystal displays. The molded pallet can carry one foam box or multiple stacked foam boxes. The molded pallet provided in this application embodiment is highly scalable and can also be extended to other industries, such as chemical and logistics industries.

[0048] Figure 2 This is a three-dimensional structural diagram of a molded panel 120 provided in an embodiment of this application. Please refer to... Figure 2 In one feasible implementation, the molded panel 120 has a plurality of positioning rings 121 on the side facing the base plate 111, and the plurality of positioning rings 121 correspond one-to-one with a plurality of auxiliary support parts.

[0049] The end of the support pier 112 is connected to the corresponding auxiliary support within the area enclosed by the corresponding positioning ring 121.

[0050] Multiple positioning rings 121 provide positioning and limiting for the connection of multiple support blocks 112 and multiple auxiliary support parts, facilitating quick alignment and connection of the molding bracket 110 and the molding panel 120, thereby improving the production efficiency of the molding tray. Furthermore, the positioning rings 121, in conjunction with the corresponding auxiliary support parts, also provide more contact surface at the ends of the support blocks 112, ensuring the connection strength between the molding bracket 110 and the molding panel 120.

[0051] It is understood that the auxiliary support portion refers to the plate body at the molded panel 120 corresponding to the positioning ring 121, and the main support portion refers to the plate body at the molded panel 120 corresponding to the area other than the multiple auxiliary support portions. That is, the molded panel 120 is composed of the plate body corresponding to the main support portion and the plate bodies at the multiple auxiliary support portions.

[0052] Figure 3This is a schematic cross-sectional view of a molded bracket provided in an embodiment of this application. Figure 4 This is a schematic diagram of another cross-sectional structure of a molded bracket provided in an embodiment of this application. Figure 5 This is a partially enlarged structural diagram of a molded bracket provided in an embodiment of this application.

[0053] Please see Figures 3-5 In one feasible embodiment, the molded panel 120 facing the base plate 111 also has a first mating part 122 located in the area enclosed by the positioning ring 121; the end of the support block has a second mating part 1121 that engages with the first mating part 122.

[0054] The first mating part 122 and the second mating part 1121 are mated together in a concave-convex manner, which can increase the contact area between the support pier 112 and the corresponding auxiliary support part, thereby improving the connection strength between the support pier 112 and the auxiliary support part.

[0055] Specifically, in some feasible embodiments, the first mating part 122 has a first mating arc surface on the side facing the second mating part 1121, and the second mating part 1121 has a second mating arc surface on the side facing the first mating part 122, with the first mating arc surface and the second mating arc surface in contact.

[0056] The support pier 112 and the molded panel 120 are attached to each other through the first mating arc surface and the second mating arc surface, that is, the support pier 112 and the auxiliary support part are in a concave-convex fit, which can increase the contact area between the support pier 112 and the auxiliary support part, thereby ensuring the connection strength between the support pier 112 and the auxiliary support part.

[0057] Figure 6 This is a partially enlarged schematic diagram of another molded bracket provided in an embodiment of this application. Figure 7 This is a partially enlarged structural schematic diagram of another molded bracket provided in the embodiments of this application.

[0058] Please see Figures 6-7 For example, one of the first mating arc surface and the second mating arc surface is a convex arc surface, and the other of the first mating arc surface and the second mating arc surface is a concave arc surface.

[0059] For example, Figure 6 As shown, the first mating arc surface on the support pier 112 is a convex arc surface, and the second mating arc surface on the molding panel 120 that contacts the support pier 112 is a concave arc surface. The concave arc surface on the molding panel 120 wraps around the convex arc surface on the support pier 112. For example... Figure 7As shown, the first mating arc surface on the support pier 112 is an arc-shaped concave surface, and the second mating arc surface on the molded panel 120 that contacts the support pier 112 is an arc-shaped convex surface. The arc-shaped concave surface on the support pier 112 wraps around the arc-shaped convex surface on the molded panel 120.

[0060] To ensure the contact area between the curved convex and curved concave surfaces, the curvatures of both surfaces are consistent. A smaller curvature corresponds to a smoother surface, reducing the likelihood of stress concentration between the support pier 112 and the contacting molded panel 120. Conversely, a larger curvature corresponds to a steeper surface, increasing the likelihood of stress concentration between the support pier 112 and the contacting molded panel 120. This can easily puncture or deform the molded panel 120. Therefore, to avoid stress concentration between the support pier 112 and the molded panel 120, the curvature of both the curved concave and curved convex surfaces is less than or equal to 1 / 80.

[0061] For example, both the arc-shaped convex surface and the arc-shaped concave surface are semi-elliptical arc surfaces or both are hemispherical surfaces.

[0062] Figure 8 This is a partially enlarged structural diagram of another molded bracket provided in an embodiment of this application. Please refer to... Figure 8 Specifically, in some other feasible embodiments, the first mating part 122 has a plurality of first teeth on the side facing the second mating part 1121, and the second mating part 1121 has a plurality of second teeth on the side facing the first mating part 122, and the plurality of first teeth and the plurality of second teeth mesh with each other.

[0063] The support block 112 and the molded panel 120 are connected by multiple first teeth and multiple second teeth meshing together, which can effectively increase the contact area between the support block 112 and the molded panel 120 and enhance the bonding strength between the support block 112 and the molded panel 120.

[0064] For example, the end of the support pier 112 facing the molding panel 120 has five first teeth, and the side of the molding panel 120 facing the support pier 112 has five corresponding second teeth. The side lengths of the first and second teeth are the same, for example, both the first and second teeth are 5-7 mm. It should be noted that the side lengths of the first and second teeth refer to... Figure 8 The dimension in the horizontal direction.

[0065] Figure 9 and Figure 10 These are all schematic diagrams of a three-dimensional structure of a molded bracket provided in the embodiments of this application. Figure 11 yes Figure 9 or Figure 10 A three-dimensional structural diagram of the medium-molded support from another perspective.

[0066] Please see Figures 9-11 In some feasible embodiments, the base plate 111 includes at least two first plates 114 and at least three second plates 115 connected together. The at least two first plates 114 are spaced apart along a first direction, and the at least three second plates 115 are spaced apart along a second direction. The first and second directions intersect, for example, the first and second directions are perpendicular. In other embodiments, the base plate 111 includes at least three first plates 114 and at least two second plates 115 connected together. The at least three first plates 114 are spaced apart along a first direction, and the at least two second plates 115 are spaced apart along a second direction. The first and second directions intersect. Specifically, for example, the base plate 111 includes three first plates 114 and three second plates 115 connected together. The number and arrangement of the first plates 114 and the second plates 115 can be adjusted according to actual needs, and are not exhaustively listed here.

[0067] Two adjacent first plates 114 in the first direction and two adjacent second plates 115 in the second direction are used to form a hollow area, so that at least two hollow areas can be formed on the base plate 111. At least two support blocks 112 are fixed on both the first plate 114 and the second plate 115, and the support block 112 on the first plate 114 is the first support block 112a, and the support block 112 on the second plate 115 is the second support block 112b.

[0068] A rectangular base plate 111 and a rectangular cutout area can be formed by at least two first plates 114 spaced apart along a first direction and at least three second plates 115 spaced apart along a second direction. The rectangular shape of the base plate 111, and the shape of the molding panel 120 matching the shape of the base plate 111, allows the molding panel 120 to provide a larger support surface for the supported items, facilitating the support of larger or more items. The rectangular cutout area creates a larger cutout effect on the base plate 111, helping to reduce the weight and material usage of the base plate 111.

[0069] Each first plate 114 and each second plate 115 is fixed with at least two support blocks 112, which can ensure that the molding bracket 110 provides better support for the molding panel 120, or strengthen the support strength of the molding bracket 110 so that the molding tray can bear heavier items.

[0070] Please see Figures 9-10Specifically, in some feasible embodiments, the number of first support piers 112a on the first plate 114 is the same as the number of second plates 115, and at least three first support piers 112a on the first plate 114 correspond to at least three second plates 115. The second support piers 112b on the second plate 115 are arranged in a row with their corresponding first support piers 112a in the first direction. This arrangement effectively reduces the number of first support piers 112a, decreases the material usage of the molding bracket 110, and ensures the overall support strength of the molding bracket 110 for the molding panel 120. The arrangement of the second support piers 112b on the second plate 115 with their corresponding first support piers 112a in the first direction facilitates joint support of the molding panel 120 by the first support piers 112a and 112b in the first direction, ensuring a greater combined support effect between the first support piers 112a and 112b.

[0071] Please see Figures 9-10 For example, in a row of support piers 112 arranged in the first direction, the distance between adjacent first support piers 112a and second support piers 112b is less than the distance between two adjacent second support piers 112b in the first direction, and less than the distance between two adjacent first support piers 112a in the second direction.

[0072] By making the distance between two adjacent first support blocks 112a in the second direction and the distance between two adjacent second support blocks 112b in the first direction relatively large, the molded pallet can be easily handled by cooperating with the corresponding transfer equipment in the first or second direction. For example, if the distance between two adjacent first support blocks 112a in the second direction and the distance between two adjacent second support blocks 112b in the first direction are both slightly larger than the fork tines of a forklift, the forklift tines can be inserted into the channel between two adjacent rows of support blocks in the second direction or between two adjacent rows of second support blocks 112b in the first direction.

[0073] In a row of support piers 112 arranged in the first direction, the distance between adjacent first support piers 112a and second support piers 112b is smaller than the distance between two adjacent first support piers 112a in the second direction and the distance between two adjacent second support piers 112b in the first direction. On the one hand, this facilitates the compact design of the molded tray, and on the other hand, it helps to ensure the support strength of the molded bracket 110.

[0074] Specifically, for example Figures 9-10 As shown, along the first direction, the second plate 115 has three equally spaced second support piers 112b.

[0075] Please see Figures 9-10 For example, the width of the base plate 111 corresponds to the dimension in the second direction, the length of the base plate 111 corresponds to the dimension in the first direction, and the width of the base plate 111 is less than the length of the base plate 111.

[0076] The portion of the first plate 114 located between two adjacent first support piers 112a includes at least two first reinforcing ribs 116 and at least one auxiliary reinforcing rib 117. The two ends of each first reinforcing rib 116 are connected to the two adjacent first support piers. An auxiliary reinforcing rib 117 is distributed between the two adjacent first reinforcing ribs 116 in a first direction, and the end of the auxiliary reinforcing rib 117 is separated from the first support pier. The at least two first reinforcing ribs 116 and at least one auxiliary reinforcing rib 117 facilitate the enhancement of the strength of the first plate 114.

[0077] The portion of the second plate 115 located between two adjacent second support piers 112b has at least two second reinforcing ribs 118, with each end of the second reinforcing rib 118 connected to one of the two adjacent second support piers. The two second reinforcing ribs 118 facilitate the enhancement of the strength of the second plate 115.

[0078] When the strength of the first plate 114 and the strength of the second plate 115 are both enhanced, the strength of the entire molding bracket 110 can be effectively increased, thereby ensuring the support strength of the molding bracket 110 to the molding panel 120.

[0079] Specifically, for example Figures 9-10 As shown, the portion of the first plate 114 located between two adjacent first support piers 112a has: two first reinforcing ribs 116 and one auxiliary reinforcing rib 117. The two first reinforcing ribs 116 are symmetrically distributed about the auxiliary reinforcing rib 117. The auxiliary reinforcing rib 117 is elongated, and the two first reinforcing ribs 116 are arc-shaped or bent. The portion of the second plate 115 located between two adjacent second support piers 112b has: two second reinforcing ribs 118. The two second reinforcing ribs 118 are symmetrically distributed and are both arc-shaped or bent.

[0080] Specifically, the spacing between the two first reinforcing ribs 116 between two adjacent first support piers 112a initially increases and then decreases as they move away from one of the first support piers 112a, reaching its maximum value at the midpoint between the two first support piers 112a. This helps to increase the moment of inertia of the first plate 114 and its bending strength, preventing the first plate 114 from bending during use. Similarly, the spacing between the two second reinforcing ribs 118 between two adjacent second support piers 112b initially increases and then decreases as they move away from one of the second support piers 112b, reaching its maximum value at the midpoint between the two second support piers 112b.

[0081] Please see Figures 9-10 Specifically, in some feasible embodiments, the base plate 111 further includes a third reinforcing rib 119. In a row of support piers 112 arranged in the first direction, the third reinforcing rib 119 is distributed between adjacent first support piers 112a and second support piers 112b, and the two ends of the third reinforcing rib 119 are respectively connected to the adjacent first support piers and second support piers.

[0082] The third reinforcing rib 119 effectively strengthens the base plate 111 and the adjacent first support pier 112a and second support pier 112b. The first reinforcing rib 116, the second reinforcing rib 118, the third reinforcing rib 119, and the auxiliary reinforcing rib 117 work together to effectively improve the strength of the entire molded support 110.

[0083] Please see Figure 2 In some feasible embodiments, the molded panel 120 has a plurality of fourth reinforcing ribs 123 on the side facing the molded support 110. Some of the fourth reinforcing ribs 123 are connected head to head of adjacent fourth reinforcing ribs 123 to form a reinforcing rib ring, and the remaining fourth reinforcing ribs 123 are distributed within the reinforcing rib ring. The remaining fourth reinforcing ribs 123 can be separated from the reinforcing rib ring.

[0084] By increasing the strength of the molded panel 120 through the fourth reinforcing rib 123, the strength of both the molded bracket 110 and the molded panel 120 is improved, which can significantly enhance the strength of the molded tray and make it easier for the molded tray to bear heavier or more items.

[0085] Please see Figures 5-8 In some feasible embodiments, the support pier 112 includes: an integrally formed support plate 1122 and a support sidewall 1123.

[0086] The support plate 1122 is located at one end of the support side wall 1123 and together with the support side wall 1123 to form an inner cavity. The end of the support side wall 1123 facing away from the support plate 1122 is fixedly connected to the base plate 111 at the opening 113.

[0087] The support plate 1122 is connected to the auxiliary support part. The thickness of the support plate 1122 is greater than the maximum thickness of the support side wall 1123 and greater than the thickness of the bottom plate 111.

[0088] The support plate 1122 on the support pier 112 has a smaller area compared to the entire base plate 111 or the molding bracket 110. Since the support plate 1122 is connected to the molding panel 120 and supports the molding panel 120 and the weight of the items placed on it, it requires significant structural strength to ensure effective support for the molding panel 120 and the items on it. When the thickness of the support plate 1122 is greater than the maximum thickness of the support sidewall 1123 and also greater than the thickness of the base plate 111, the structural strength of the support plate 1122 is effectively guaranteed, thus ensuring its supporting performance so that the molding tray can stably support the items.

[0089] It is understandable that the end of the supporting sidewall 1123 facing away from the supporting plate 1122 is fixedly connected to the base plate 111 at the opening 113. This can mean that the end of the supporting sidewall 1123 facing away from the supporting plate 1122 is fixedly connected to the base plate 111 facing the side of the molding panel 120 at the opening 113, or it can mean that the end of the supporting sidewall 1123 facing away from the supporting plate 1122 is fixedly connected to the base plate 111 on the inner wall of the opening 113. When the end of the support sidewall 1123 facing away from the support plate 1122 is fixedly connected to the inner wall of the opening 113 and the bottom plate 111, the end of the support sidewall 1123 in the opening 113 needs to be flush with the side of the bottom plate 111 facing away from the molding panel 120, or the end of the support sidewall 1123 in the opening 113 is located inside the opening 113, so as to ensure that the side of the bottom plate 111 facing away from the molding panel 120 is a relatively flat surface, thereby ensuring the transportation effect of the molding pallet on the transport roller line.

[0090] Please see Figures 3-8 In some feasible embodiments, the radial dimension of the support sidewall 1123 gradually decreases along the direction from the base plate 111 to the molded panel 120.

[0091] When the radial dimension of the support sidewall 1123 gradually decreases along the direction from the base plate 111 to the molding panel 120, it is convenient to manufacture the molding bracket 110, for example, to facilitate demolding.

[0092] It is understandable that when the inner and outer walls of the support sidewall 1123 have the same shape, that is, when the wall thickness of the support sidewall 1123 is the same, the radial dimension of the support sidewall 1123 gradually decreases along the direction from the base plate 111 to the molding panel 120. This means that the radial dimensions of both the inner and outer walls of the support sidewall 1123 gradually decrease along the direction from the base plate 111 to the molding panel 120. For example, the inner and outer walls of the support pier 112 are both frustum-shaped or frustum-shaped. When the inner and outer wall shapes of the support sidewall 1123 are inconsistent, that is, when the wall thickness of the support sidewall 1123 is inconsistent, the radial dimension of the support sidewall 1123 gradually decreases along the direction from the base plate 111 to the molding panel 120. This means that the radial dimension of the inner or outer wall of the support sidewall 1123 gradually decreases along the direction from the base plate 111 to the molding panel 120. For example, the inner wall of the support sidewall 1123 is cylindrical and the outer wall of the support sidewall 1123 is frustum-shaped, or the inner wall of the support sidewall 1123 is frustum-shaped and the outer wall of the support sidewall 1123 is cylindrical, or the inner wall of the support sidewall 1123 is cylindrical and the outer wall of the support sidewall 1123 is frustum-shaped.

[0093] Please see Figures 5-8 In some feasible embodiments, the outer surface of the support sidewall 1123 has multiple step groups, which are arranged sequentially in the axial direction of the support pier 112, and each step group includes at least one step, with at least one step in a step group distributed around the inner cavity.

[0094] Specifically, in this embodiment, the inner and outer walls of the support sidewall 1123 have the same shape, for example, both are frustum-shaped or both are truncated pyramidal. When the inner and outer walls of the support sidewall 1123 have the same shape and are both frustum-shaped or both are truncated pyramidal, although it is convenient to process and manufacture, during the molding process, there may be a shortage of material in some parts of the support sidewall 1123.

[0095] By providing multiple sets of steps on the outer side of the support sidewall 1123, and having these sets of steps arranged sequentially along the axial direction of the support pier 112, the thickness of the support sidewall 1123 can be effectively increased, preventing local material shortages or deficiencies in the support sidewall 1123. Furthermore, the strength of the support sidewall 1123 can be enhanced, giving the support pier 112 better support and improving the load-bearing capacity of the molded pallet.

[0096] It should be noted that the aforementioned step group refers to the step group located at the same axial position on the supporting sidewall 1123, and the step group may include one or more steps.

[0097] When a step group includes multiple steps, the multiple steps are distributed circumferentially around the inner cavity of the support pier 112. Multiple steps in the same step group can be connected end to end circumferentially to form a ring of steps, or multiple steps in the same step group can be distributed at intervals circumferentially.

[0098] The number and distribution of steps in different step groups can be the same or different. For example, a step group on the first floor may include multiple steps that are connected end to end in the circumference, while a step group on an adjacent floor in the axial direction may include multiple steps that are spaced apart in the circumference. It can be understood that "multiple" means two, three, four, etc.

[0099] Specifically, in this embodiment, in order to facilitate processing and fully ensure the strength of the supporting sidewall 1123, each layer of steps along the axial direction of the supporting sidewall 1123 includes multiple steps, and the multiple steps are connected end to end to form a ring of steps, that is, each layer of steps is a ring of steps.

[0100] In some feasible implementations, the thickness of the support plate 1122 is greater than or equal to the thickness of the molded panel 120.

[0101] The molded tray also includes a connector, and the support block 112 is connected to the molded panel 120 via the connector.

[0102] The cross-sectional area of ​​the support plate 1122 is smaller than that of the molded panel 120, meaning the cross-sectional area of ​​the support plate 1122 is relatively smaller than that of the molded panel 120. This allows the thickness of the support plate 1122 to be greater than or equal to the thickness of the molded panel 120. This helps ensure the strength of the support plate 1122, thereby ensuring its supportive properties.

[0103] Since the support plate 1122 and support sidewall 1123 in the support block 112 are integrally formed structures, and the support block 112 and base plate 111 in the molded bracket 110 are integrally formed structures, when assembling the molded tray, it is only necessary to connect the molded panel 120 and the support plate 1122 on the support block 112 through the connector, which effectively reduces the number of parts that need to be connected in the molded tray and reduces processing costs.

[0104] For example, the connector is a threaded nail, which is threadedly connected to the molding panel 120 and the support plate 1122 to achieve a stable connection between the molding bracket 110 and the molding panel 120. The threaded nail allows for a detachable connection between the molding bracket 110 and the molding panel 120, facilitating the recycling and reuse of both components, making it more low-carbon and environmentally friendly, and reducing costs.

[0105] For example, the thickness h1 of the support plate 1122 is 20-25 mm, and the thickness h2 of the molding panel 120 is 15-20 mm. Within this thickness range, the molding panel 120 and the support plate 1122 can also increase the contact thickness between the threaded nail and the molding tray, thereby enhancing the nail's strength and ensuring the connection stability or connection strength between the molding bracket 110 and the molding panel 120.

[0106] The molded tray in the above embodiments of this application features a support block 112 designed on the base plate 111 of the molding bracket 110, with the opening of the support block 112 facing the base plate 111. The support block 112 in the molding bracket 110 is connected to the auxiliary support portion in the molding panel 120. The side of the main support portion away from the molding bracket 110 is flush with the side of the auxiliary support portion away from the molding bracket 110. This ensures that the surface of the molding panel 120 away from the molding bracket 110 is relatively flat, facilitating the provision of uniform support force to the items carried on it and effectively preventing damage caused by uneven force on the items carried on the molded tray. The integrally molded bracket 110 reduces the number of parts in the molded tray, correspondingly reducing the number of connection points, thereby lowering material and processing costs. The molding bracket 110 and the molding panel 120 are detachably connected by threaded fasteners, facilitating the disassembly and recycling of the molded tray. By optimizing the structure of the support pier 112, the supporting performance of the support pier 112 can be increased, and the bonding strength between the molding bracket 110 and the molding panel 120 can be guaranteed. Compared with the nine-corner molding pallet, the molding pallet in this embodiment can be adapted to the transport roller line, so that the molding pallet can move smoothly on the transport roller line.

[0107] This application also provides a transportation system, including: a transportation mechanism and a molded pallet as described above.

[0108] The transport mechanism includes multiple rollers arranged side-by-side and spaced apart along the transport direction, used to convey molded pallets along the transport direction. These rollers form a transport roller line as described above along the transport direction.

[0109] The transportation system includes the molded pallet in the above embodiments, and therefore also has the advantages of the molded pallet in the above embodiments, so it will not be described again here.

[0110] In one feasible implementation, the transport system further includes a handling mechanism for handling the molded pallet to the transport roller line, or for removing the molded pallet from the transport roller line.

[0111] Among them, the handling mechanism, such as a forklift, achieves the handling function by inserting its forks into the insertion channel formed in the molded pallet.

[0112] Handling mechanisms can improve the efficiency or automation of transportation systems and free up manpower.

[0113] The transportation system provided in this application can be applied, for example, to a liquid crystal display packaging production line to assist in the packaging of liquid crystal display products. Of course, the transportation system is highly scalable and can be extended to other industries; this application does not impose specific limitations.
