Description

Technical Field

[0001] The utility model belongs to the field of transport boxes, and in particular relates to a paper-wood combined pallet and a transport box. Background Art

[0002] Pallets are important cargo platforms in the process of logistics and transportation. They realize the unitization, standardization and efficiency of cargo circulation, improve the efficiency and quality of logistics operations, reduce the risk of cargo collision damage, and reduce logistics costs. At present, the commonly used pallets on the market are wooden pallets, plastic pallets, metal pallets, paper pallets, and other composite material pallets. Due to the high comprehensive cost performance of wooden pallets, they have become the first choice of various industries. However, the processing of wooden pallets requires a large amount of wood resources, which directly consumes forest resources. This is contrary to the current dual carbon goals of "carbon neutrality" and "carbon peak" proposed at home and abroad. Therefore, various industries have begun to think about how to reduce the use of wooden pallets. For the logistics transportation of lighter goods, paper pallets can be used as a substitute. For the long-distance transportation of heavy goods, the requirements for the load-bearing strength and weather resistance of pallets are relatively high, so wooden pallets still need to be used. The structure of wooden pallets will be customized according to the actual needs of the goods, and generally includes bottom plates, foot piers, reinforcement plates, and panels. For heavy products, such as automotive power batteries, the product weight ranges from about 300 to 700kg, and the weight of the wooden pallet ranges from 100 to 200kg. When the container reaches the vehicle load limit, the container space utilization rate is still relatively low. If the weight of the packaging box and pallet can be reduced while ensuring the safety of the packaging, the number of boxes in the container can be increased, thereby reducing the freight cost per product.

[0021] Figure numerals: 1 - front vertical plate 2 - rear vertical plate 3 - left vertical plate 4 - right vertical plate 5 - horizontal boss 6 - horizontal groove 7 - vertical boss 8 - vertical groove 9 - inclined surface 10 - bottom support 11 - horizontal reinforcement plate 12 - top panel 13 - longitudinal reinforcement plate 14 - filling plate 15 - bottom plate 16 - top frame 17 - foot pier 18 - enclosure box.

[0022] like Figure 1 As shown in Figure 5, the utility model provides a paper-wood combined pallet, which includes at least two bottom brackets 10, at least two transverse reinforcing plates 11 arranged on the bottom brackets 10, a top frame 16 arranged on the transverse reinforcing plates 11 and surrounding the top surface of the pallet, and a top panel 12 arranged on the transverse reinforcing plates 11 and placed in the top frame 16. The overall structure of the pallet supports the material through two bottom brackets 10, making it convenient for forklifts to pick up the material. The horizontal structural strength of the pallet is ensured by the horizontal reinforcement plates 11 fixed on the bottom brackets 10. The top frame 16 is installed around the horizontal reinforcement plates 11 to protect the sides of the top panel 12 installed on the horizontal reinforcement plates 11 to avoid being hit by a forklift. When in use, the material is placed on the top panel 12 and the top frame 16. The simplest structure relative to the pallet is that the number of bottom brackets 10 and the number of horizontal reinforcement plates 11 are two, and the specific number can be determined according to the volume and weight of the carried material. When the carried material is larger and heavier or smaller and heavier, the corresponding bottom brackets 10 will be more, and the number of horizontal reinforcement plates 11 will also be more. When the carried material is smaller and lighter or larger and lighter, the corresponding bottom brackets 10 will be fewer, and the number of horizontal reinforcement plates 11 will also be fewer. The number of bottom brackets 10 and the number of horizontal reinforcement plates 11 can also be increased according to demand.

[0023] The pallet further includes a plurality of filling plates 14 disposed on the base 10 and between the two transverse reinforcing plates 11. The filling plates 14 are added between the transverse reinforcing plates 11 to ensure that the bottom of the top panel 12 is supported all around to prevent deformation of the suspended position around the top panel 12 due to excessive weight of the material.

[0024] The base support 10 includes a base plate 15, at least two foot piers 17 disposed on the base plate 15, and a longitudinal reinforcing plate 13 disposed on the foot piers 17. The base support 10 provides sufficient forklift space by supporting the foot piers 17 with the base plate 15 and the longitudinal reinforcing plate 13, and the foot piers 17 are fixed between the base plate 15 and the longitudinal reinforcing plate 13 in a uniformly distributed manner, such as two foot piers 17, distributed at both ends, and three foot piers 17, distributed at both ends and the middle, and so on. The foot piers 17 are fixed to the base plate 15 by means of row nails, and the longitudinal reinforcing plate 13, the transverse reinforcing plate 11 and the top frame 16 are also fixed to the foot piers 17 by means of row nails.

[0025] The foot pier 17 is a solid wood foot pier. The use of a solid wood foot pier can make the pallet have a greater load-bearing capacity, but it will increase the overall weight of the pallet. Therefore, when the material is particularly heavy and the hollow solid wood foot pier is not enough to support it, this solid wood foot pier is selected; if it does not exceed the support of the hollow solid wood foot pier, a hollow solid wood foot pier can be selected to reduce the overall weight of the pallet.

[0026] The foot pier 17 is a hollow solid wood foot pier, such as Figure 3As shown in Figure 5, the foot pier 17 includes a front vertical plate 1, a rear vertical plate 2, a left vertical plate 3 and a right vertical plate 4 forming a square structure; the front vertical plate 1 has the same structure as the rear vertical plate 2, has inclined surfaces 9 at both ends, and is provided with a horizontal boss 5 and a horizontal groove 6 in the horizontal direction; the left vertical plate 3 has the same structure as the right vertical plate 4, has inclined surfaces 9 at both ends that are complementary to the inclined surfaces 9 of the front vertical plate 1 and the rear vertical plate 2, and is provided with a vertical groove 8 and a vertical boss 7 that cooperate with the horizontal boss 5 and the horizontal groove 6 in the vertical direction; the front vertical plate 1, the rear vertical plate 2, the left vertical plate 3 and the right vertical plate 4 are mortise and tenoned together by the complementary horizontal boss 5 and the vertical groove 8 and the complementary horizontal groove 6 and the vertical boss 7. The horizontal boss 5 or vertical boss 7 and the horizontal groove 6 or vertical groove 7 on the front vertical plate 1, the rear vertical plate 2, the left vertical plate 3 and the right vertical plate 4 are all processed by an inclined mortise and tenon tool. The horizontal boss 5 and the horizontal groove 6 are complementary to each other, and one side of the horizontal boss 5 and one side of the horizontal groove 6 are on the same horizontal line, that is, the horizontal boss 5 and the horizontal groove 6 have one side that is coplanar, and the same is true for the vertical boss 7 and the vertical groove 8. The front vertical plate 1, the rear vertical plate 2, the left vertical plate 3 and the right vertical plate 4 are mortised together by means of bosses and grooves, which are more stable and firm than conventional overlapping and abutting structures, and can also ensure the bearing strength.

[0027] The inclined surface is 40-50°. The inclined surface is 45°. The inclined surface 9 can be made into 40-50° to achieve mortise and tenon splicing, but the splicing angle needs to be 90°, that is, if the inclined surfaces 9 at both ends of the front vertical plate 1 and the rear vertical plate 2 are made into 40°, in order to cooperate with the use of the front vertical plate 1 and the rear vertical plate 2, the inclined surfaces 9 at both ends of the left vertical plate 3 and the right vertical plate 4 need to be made into 50° to form mutual compensation, and vice versa. However, during production, due to the different angles of the inclined surfaces 9, it is necessary to replace the mortise knife for separate production. If the inclined surface 9 is made into 45°, the inclined surfaces 9 at both ends of the front vertical plate 1, the rear vertical plate 2, the left vertical plate 3 and the right vertical plate 4 are all 45°, forming mutual compensation. During production, due to the same angle of the inclined surfaces 9, it is not necessary to replace the mortise knife for separate production.

[0028] The top panel 12 is one or more of corrugated paperboard, honeycomb paperboard or corrugated composite board. Since the corrugated paperboard, honeycomb paperboard or corrugated composite board are all hollow structures, compared with wooden boards, they have low density and light weight, do not require multiple people to carry, and are convenient for processing and assembly; in addition, the honeycomb structure or wave structure in the middle has good bearing strength, and compared with wooden boards, has a certain compressible resilience, has a buffering and shock absorbing effect, and is low in cost compared with wooden boards.

[0029] like Figure 6As shown, a transport box includes the pallet, a box 18 disposed on the pallet, and an upper cover plate (not shown in the figure) disposed on the box 18. The box 18 of the transport box contacts the pallet, and the weight is borne by the top frame 16 and transferred to the filling plate 14, the longitudinal reinforcing plate 13, the foot pier 17 and the bottom plate 15, which are all made of wood materials, are relatively pressure-resistant, and avoid the possibility of squeezing and deforming the top panel 12.

[0030] The enclosure 18 and the upper cover are made of paper material or wood material. A suitable enclosure 18 is selected according to the volume and weight of the material to be carried. In addition, different enclosures 18 can be selected according to different needs. If paper material is selected, the weight of the transport box can be reduced, but there will be a slight lack of load-bearing capacity. If wood material is selected, the weight of the transport box will be increased, but it can bear a heavier load.

[0031] This type of pallet combines paper and wood. The paper material used as the pallet panel has a relatively smooth and flat surface. There is no need to add soft foam gaskets for isolation and protection when in contact with the product, which can reduce the use of auxiliary materials. Paper boards are all hollow structures. Compared with wooden boards, they have low density and light weight. They do not require multiple people to carry and are convenient for processing and assembly. For heavy product packaging, under weight-limited conditions, the packaging weight can be reduced, the packaging quantity can be increased, and the product-spreading freight can be reduced. The honeycomb structure or wave structure in the middle of the paper board has good planar bearing strength. Compared with wooden boards, paper boards have a certain compressible resilience and have a cushioning and shock-absorbing effect. Compared with wooden boards, paper boards are lower in cost.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
