Description

Technical Field

[0001] This utility model belongs to the field of molded trays, and more specifically, relates to a molded tray. Background Technology

[0002] As the most basic containerization equipment in unitized logistics, pallets are closely related to the development of the logistics industry. In recent years, the logistics industry has grown steadily, and with the nationwide implementation of palletized transport, the pallet industry has also flourished. Pallets, as the main component in cargo movement and handling, are primarily used to protect goods, automate cargo transportation, and improve cargo flow efficiency. In today's bulk commodity trading system, weight is mostly used as the unit of measurement for transaction value, such as for weighing the goods themselves, preventing overweight transport vehicles, and measuring real-time weight increases or decreases during cargo use. Therefore, enabling the visualization of cargo weight would greatly improve trade efficiency.

[0003] Molded pallets, also known as plant fiber molded flat industrial pallets, are typically made from raw materials such as wood shavings, plant straw, and bamboo. They feature a one-piece structure, with the panel and support legs molded in a single process. The upper surface of the pallet is smooth and flat, suitable for transporting various goods, while the lower surface has reinforcing ribs. The pallet surface has balanced longitudinal and transverse stress, and multiple support legs allow for four-way forklift entry, making it a flat, four-way entry single-sided pallet.

[0004] Since molded pallets are made from recyclable resources such as straw, branches, wood chips, bamboo chips, and bamboo fertilizer, and the production process usually uses hot pressing, both the raw materials and the process are relatively environmentally friendly. Therefore, molded pallets are increasingly becoming the mainstay of the pallet market, and research on molded pallets is becoming more and more intensive. How to better utilize environmentally friendly raw materials and how to improve the load-bearing capacity and strength of pallets are key research directions for molded pallets.

[0005] Molded pallets, which secure cylindrical cargo, require precise calculations and design of each part of the mold to ensure a tight fit between the cylinder and the rest of the pallet. This necessitates high-precision machining techniques and rigorous quality control to ensure the cylinder is stably fixed in the accurate position. It also requires consideration of how to effectively absorb impact energy during loading to prevent the cargo from slipping on the pallet.

[0006] Therefore, in order to solve the above problems, there is an urgent need to find a molded tray. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a molded pallet, including a pallet base with multiple foot blocks. The pallet base is used to secure barrel-shaped goods, and the foot blocks support the pallet base. Each foot block has a concave surface and a convex surface. When the pallet base and barrel-shaped goods are stacked, the foot blocks of the pallet base on top of the barrel-shaped goods can secure the upper base of the barrel-shaped goods through their concave surfaces and convex surfaces. When storing barrel-shaped goods, the concave surfaces of the foot blocks can also engage with specially designed shelves, increasing the stability of the pallet base. The pallet base not only has limiting blocks to define and secure the lower base of the barrel-shaped goods, but also reinforcing ribs that are interlaced with the foot blocks to enhance the strength and rigidity of the molded pallet, thereby improving its load-bearing capacity and service life. The foot blocks can also be fitted with detachable support rods to protect the molded pallet in special environments.

[0008] A molded pallet includes a pallet base with foot blocks for securing goods; the foot blocks support the pallet base; when the molded pallet and goods are stacked in multiple layers, the foot blocks on top of the goods not only support the pallet base but also secure the goods below them.

[0009] In some methods, when goods are secured on a molded pallet, the foot blocks serve to support the pallet base and the goods fixed to it. Additionally, when molded pallets and goods are stacked in two or more layers, except for the top layer of goods, the remaining goods form a lower pallet base-goods-upper pallet base structure. In this case, the goods are secured by both upper and lower pallet bases. The lower base of the goods is secured by the limiting blocks of the lower pallet base, and the upper base is secured by the foot blocks of the upper pallet base, thus providing double securing. During transportation, this double securing makes the goods more stable, less prone to slippage, and increases the stability and safety of the transportation process. During loading and unloading, multi-layer stacking improves the efficiency of goods transfer. It is important to note that the foot blocks and pallet bases have certain load-bearing limits, so molded pallets and goods cannot be stacked indefinitely.

[0010] Furthermore, the foot block is provided with a concave surface and a convex surface. The concave surface can be inserted into the shelf, and the concave surface and the convex surface can be used together to fix the upper chassis of the goods. The foot block includes a first foot block, a second foot block and a third foot block.

[0011] In some designs, the pallet base features three different sized feet: a first foot, a second foot, and a third foot. Each foot has a varying number of concave and convex surfaces. These concave and convex surfaces are opposite each other, lying on the same plane. A portion is cut downwards from the concave surface, and the remaining portion is called a convex surface. When storing goods, the molded pallet's feet can be placed directly on a flat surface, with the convex surfaces in contact with the surface. Alternatively, the molded pallet can be placed on a specially designed shelf, where the concave surfaces of the feet act as slots, engaging with the convex surfaces of the shelf to increase storage stability. Although the feet are of different sizes, their regular distribution on the pallet base ensures that a forklift can easily access and load / unload goods.

[0012] In some configurations, the first foot block has two protrusions and two concave surfaces, arranged in the order of concave-protrusion-concave-protrusion; the second foot block has two concave surfaces and one protrusion, arranged in the order of concave-protrusion-concave; and the third foot block has two concave surfaces and one protrusion, arranged in the order of concave-protrusion-concave. The foot blocks are arranged symmetrically, with three rows arranged horizontally on the base of the tray, each row equally spaced. The first row consists of second foot block-third foot block-second foot block, the second row consists of first foot block-first foot block, and the third row consists of second foot block-third foot block-second foot block, with equal spacing between the foot blocks in each row.

[0013] Furthermore, the number of the first footing, the second footing, and the third footing may be multiple.

[0014] In some configurations, there are two first footholds, four second footholds, and two third footholds.

[0015] Furthermore, the length of the first foot block is greater than the length of the second foot block, which in turn is greater than the length of the third foot block.

[0016] In some designs, most molded pallets have multiple identical feet on the pallet base. However, the molded pallet of this invention combines performance and function by using feet of different sizes. This not only balances the stress on the pallet base, improving its load-bearing capacity and service life, but also allows the molded feet to secure the lower layer of goods when stacked, increasing stability.

[0017] Furthermore, the tray base also includes reinforcing ribs, which include a first reinforcing rib, a second reinforcing rib, a third reinforcing rib, and a fourth reinforcing rib.

[0018] In some designs, reinforcing ribs enhance the strength and rigidity of the pallet base, while also improving its load-bearing capacity and service life. The design of the reinforcing ribs can effectively distribute and withstand pressure without increasing the wall thickness, thereby reducing pallet deformation and damage. The first reinforcing rib includes three grooves facing different directions, the second reinforcing rib includes one groove, the third reinforcing rib includes one arc-shaped groove, and the fourth reinforcing rib includes two arc-shaped grooves.

[0019] Furthermore, the first, second, third, and fourth reinforcing ribs are symmetrically arranged and connected to the foot block.

[0020] In some designs, reinforcing ribs are symmetrically arranged on the pallet base. There are four first reinforcing ribs, four second reinforcing ribs, two third reinforcing ribs, and four fourth reinforcing ribs. The first reinforcing ribs connect the first and second foot blocks, the second reinforcing ribs connect the first and third foot blocks, the third reinforcing ribs connect the two first foot blocks, and the fourth reinforcing ribs connect the second and third foot blocks. Through the staggered connections of the reinforcing ribs and foot blocks, a reinforcing rib-foot block groove network is formed on the molded pallet base, enhancing the strength and rigidity of the molded pallet.

[0021] Furthermore, the pallet base also includes multiple limiting blocks, which are used to define and secure the chassis of the goods.

[0022] In some designs, the limiting blocks are raised structures on the pallet base designed to fit the shape of the underlying chassis of the goods. When the goods are placed on the pallet base for fixation, the limiting blocks can limit and secure the goods. The molded pallet base provided by this invention is used to fix barrel-shaped goods, so the underlying chassis of the goods is circular, and the limiting blocks all have a certain curvature.

[0023] Furthermore, the limiting block includes a first limiting block, a second limiting block, a third limiting block, and a fourth limiting block, which are symmetrically arranged.

[0024] In some configurations, there are four first limiting blocks, four second limiting blocks, four third limiting blocks, and two fourth limiting blocks. Each limiting block has an arc-shaped structure for securing the base of the barrel-shaped cargo. Securing a barrel-shaped cargo requires the combined action of one first limiting block, two second limiting blocks, one third limiting block, and one fourth limiting block.

[0025] Furthermore, the pallet base is polygonal, and the number of goods fixed by the pallet base includes one or more, wherein the goods are barrel-shaped.

[0026] Preferably, the pallet base is square in shape, which can hold up to four barrel-shaped goods. The square pallet base can be divided into four identical squares, each of which can have an inscribed circle. The diameter of the barrel-shaped goods is slightly longer than the diameter of the inscribed circle. On the one hand, this makes full use of the space of the pallet base. On the other hand, when the pallet base is full of four barrel-shaped goods, the four barrel-shaped goods are tightly packed together, reducing the probability of the barrel-shaped goods slipping during transportation and increasing the stability of the pallet base.

[0027] In some cases, barrelled goods include, but are not limited to, chemical drums made of plastic, steel, composite materials, etc.

[0028] In some methods, the diameter of the barrel-shaped goods fixed by a pallet base is fixed. If barrel-shaped goods of different diameters are fixed, the molded pallet provided by this utility model needs to be enlarged or reduced proportionally to the corresponding size.

[0029] Furthermore, it also includes support rods, which are detachable and include a first support rod and a second support rod. The first support rod and the second support rod can be fixed to the concave surface of the foot block, and each foot block can be fixed with one or two support rods.

[0030] In some applications, support rods are used in specific scenarios to help molded pallets adapt to different ground conditions, ensuring stable use of the pallet base in various environments. For example, in humid environments, support rods are installed on the footrests to prevent the pallet base from absorbing moisture and expanding or contracting, maintaining pallet stability, extending the lifespan of the pallet base, and reducing the frequency of maintenance and replacement. The cross-sectional area of ​​the first support rod is larger than that of the second support rod.

[0031] In some installation methods, the first and second support rods have the same length and height but different widths, so the first support rod has a higher load-bearing capacity than the second. When installing support rods on the pallet base, depending on the actual cargo being secured, you can choose to install only the first or second support rod, or a combination of both, on the foot blocks. One support rod is fixed to the concave surface of the first foot block, two to the concave surface of the second foot block, and two to the concave surface of the third foot block. Therefore, a maximum of six support rods can be installed. However, it is crucial that regardless of the type of support rod chosen, they must be installed symmetrically, and the symmetrical support rods must be of the same type. Otherwise, uneven stress on the pallet base may lead to deformation or breakage. When installing the support rods, first install one type of support rod on one side of the pallet base, and then install the same type of support rod on the symmetrical other side. When the maximum load-bearing capacity of the pallet base is reached, six first support rods should be installed.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments described below are intended to facilitate the understanding of the present invention and do not constitute any limitation thereof.

[0048] Example 1: A molded tray

[0049] like Figure 1 As shown, a molded pallet includes a pallet base 1 and a detachable support rod 2. The pallet base 1 is used to fix barrel-shaped goods 3.

[0050] like Figure 2 , 3As shown in Figure 4, the pallet base 1 includes a first foot block 4, a second foot block 5, and a third foot block 6. There are two first foot blocks 4, four second foot blocks 5, and two third foot blocks 6. The length of the first foot block 4 is greater than the length of the second foot block 5, which is greater than the length of the third foot block 6. The first foot block 4 has a concave surface 7, a protrusion 8, a concave surface 9, and a protrusion 10. The second foot block 5 has a concave surface 11, a protrusion 12, and a concave surface 13. The third foot block 6 has a concave surface 14, a protrusion 15, and a concave surface 16. The foot blocks are arranged in three rows horizontally on the pallet base 1, with equal distances between each row. The foot blocks in the first row are arranged as second foot block 5-third foot block 6-second foot block 5, the foot blocks in the second row are arranged as first foot block 4-first foot block 4, and the foot blocks in the third row are arranged as second foot block 5-third foot block 6-second foot block 5. The foot blocks in each row are spaced equidistantly. When storing goods, the feet of the molded pallet can be placed directly on a flat surface, with the raised parts in contact with the surface. The molded pallet can also be placed on a specially designed shelf, where the concave surface of the feet acts as a slot, allowing it to engage with the raised parts of the shelf, increasing the stability of the molded pallet during storage. Although feet of different sizes are provided, their regular distribution on the pallet base ensures that a forklift can insert itself for loading and unloading goods. When the pallet base 1 is stacked with barrel-shaped goods 3, except for the topmost barrel-shaped goods 3, the remaining barrel-shaped goods will form a structure of pallet base 1-barrel-shaped goods 3-pallet base 1. In this case, the barrel-shaped goods 3 are secured by two pallet bases 1, with the lower base of the barrel-shaped goods 3 secured by the limiting blocks of the pallet base 1, and the upper base of the barrel-shaped goods 3 secured by the feet. To secure the upper base of a barrel-shaped cargo 3, the concave and convex surfaces of the foot blocks work together. The convex surfaces 8 and 10 of the first foot block 4 and the convex surface 15 of the third foot block 6 engage the edge of the upper base of the barrel-shaped cargo 3. The convex surface 12 of the second foot block 5 abuts against the inner side of the upper base of the barrel-shaped cargo 3, confining the position of the upper base of the barrel-shaped cargo 3 within the concave surface 9 of the first foot block 4 and the concave surface 14 of the third foot block 6. It is important to note that there is a height difference between the edge of the upper base of the barrel-shaped cargo 3 and its inner side. This height difference matches the height difference between the concave and convex surfaces, ensuring that the concave and convex surfaces of the foot blocks, after jointly securing the upper base of the barrel-shaped cargo 3, remain on the same horizontal plane. During transportation, the barrel-shaped cargo 3 has double securing, making it more stable and less prone to slippage, thus increasing the stability and safety of the transportation process. During loading and unloading, multi-layer stacking improves the efficiency of transferring the barrel-shaped cargo 3.

[0051] like Figure 2 , 5As shown in Figure 6, the support rod 2 is used in some special scenarios to help the molded pallet adapt to different ground conditions and ensure that the pallet base 1 can be used stably in different environments. For example, in a humid environment, installing the support rod 2 on the foot block helps prevent the pallet base 1 from absorbing moisture and expanding and contracting in a humid environment, maintaining the stability of the molded pallet, helping to extend the service life of the pallet base, and reducing the frequency of maintenance and replacement. The support rod 2 includes a first support rod 17 and a second support rod 18. The first support rod 17 and the second support rod 18 are cubes with the same length and height, only differing in width. Therefore, the cross-sectional area of ​​the first support rod 17 is larger than that of the second support rod 18, and the supporting force limit of the first support rod 17 is greater than that of the second support rod 18. When installing support rods 2, the first row of foot blocks and the third row of foot blocks are symmetrically arranged. Therefore, the concave surfaces of the first row of foot blocks and the third row of foot blocks are on the same horizontal plane. That is, the concave surfaces 11 and 13 of the second foot blocks 5 in the first row correspond to the concave surfaces 11 and 13 of the second foot blocks 5 in the third row, allowing for the installation of two support rods 2. The first row of foot blocks has six concave surfaces, which correspond to the six concave surfaces of the third row of foot blocks. Therefore, the pallet base 1 can install a maximum of six support rods 2. The two first foot blocks 4 in the second row have only two concave surfaces, so only the support rods 2 on both sides can be installed. The support rods 2 must be installed symmetrically, otherwise, the pallet base 1 will be subjected to uneven stress, resulting in deformation or breakage. When installing support rods 2 on the pallet base 1, depending on the number and weight of the barrel-shaped goods 3 being fixed, one can choose to symmetrically install only the first support rod 17, the second support rod 18, or a combination of symmetrically installing the first support rod 17 and the second support rod 18 on the pallet base 1.

[0052] like Figures 7-8 As shown, the pallet base 1 is also provided with a first limiting block 19, a second limiting block 20, a third limiting block 21, and a fourth limiting block 22. The limiting blocks are some protruding structures on the pallet base with a certain curvature. There are four first limiting blocks 19, four second limiting blocks 20, four third limiting blocks 21, and two fourth limiting blocks 22. Each limiting block has an arc-shaped structure for fixing the lower base of the barrel-shaped goods 3. There is a certain height difference between the edge and the inner side of the lower base, and the height difference is consistent with the height of the limiting block. Fixing the lower base of one barrel-shaped goods 3 requires the joint constraint of one first limiting block 19, two second limiting blocks 20, one third limiting block 21, and one fourth limiting block 22. The first limiting block 19, the second limiting block 20, and the fourth limiting block 22 are used to hold the outer edge of the base of the barrel-shaped goods 3, and the third limiting block 21 is used to abut against the inner side of the base of the barrel-shaped goods 3.

[0053] like Figure 9As shown, the pallet base 1 also includes a first reinforcing rib 23, a second reinforcing rib 24, a third reinforcing rib 25, and a fourth reinforcing rib 26. The first reinforcing rib 23 includes three grooves facing different directions, the second reinforcing rib 24 includes one groove, the third reinforcing rib 25 includes one arc-shaped groove, and the fourth reinforcing rib 26 includes two arc-shaped grooves. The reinforcing ribs are symmetrically arranged on the pallet base. There are four first reinforcing ribs 23, four second reinforcing ribs 24, two third reinforcing ribs, and four fourth reinforcing ribs. The first reinforcing ribs 23 connect the first foot block 4 and the second foot block 5, the second reinforcing ribs 24 connect the first foot block 4 and the third foot block 6, the third reinforcing ribs 25 connect the two first foot blocks 4, and the fourth reinforcing ribs 26 connect the second foot block 5 and the third foot block 6. Through the staggered connection of the reinforcing ribs and foot blocks, a reinforcing rib-foot block groove network is formed on the molded pallet base 1, enhancing the strength and rigidity of the molded pallet 1, while improving its load-bearing capacity and service life.

[0054] The molded pallet provided in this embodiment is polygonal in shape, preferably square, and can hold up to four barrel-shaped goods. The square pallet base 1 can be divided into four identical squares, each of which can have an inscribed circle. The diameter of the barrel-shaped goods 3 is slightly longer than the diameter of the inscribed circle. On the one hand, this makes full use of the space of the pallet base 1. On the other hand, when the pallet base 1 is full of four barrel-shaped goods, the four barrel-shaped goods are tightly packed together, reducing the probability of the barrel-shaped goods 3 slipping during transportation and increasing the stability of the pallet base 1.

[0055] It should be noted that the diameter of the barrel-shaped goods 3 fixed by the pallet base 1 is fixed. If barrel-shaped goods 3 of different diameters are to be fixed, the molded pallet provided by this utility model needs to be enlarged or reduced proportionally to fix barrel-shaped goods 3 of the corresponding diameter.

[0056] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
