Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to an extrusion tray. Background Art

[0002] A tray is an essential carrier for goods in modern logistics operations. It not only relates to the quality and efficiency of goods forklifting and storage, but also is an indispensable carrier tool for the goods flow on the production line. As an important loading, storage and transportation equipment in the logistics transportation process, the tray, when used in conjunction with a forklift, plays a huge role in modern logistics. The benefits brought by the tray to modern logistics are mainly reflected in the realization of unitization, standardization and standardization of item packaging, protection of items, and facilitation of logistics and business flows. There are various types of trays. Classified by material, they can be divided into wooden trays, plastic trays, steel trays, etc. Among them, the forming methods of plastic trays include two major categories: injection molding and blow molding. The production speed of injection molded trays is faster, the efficiency is higher, and trays of larger sizes can be produced. However, the cost of injection molded trays is relatively high, and the investment in production equipment is relatively large. Blown trays are generally lighter, have stronger impact resistance, longer service life, and lower production costs. However, due to their slower production speed, they are only suitable for small batch production and customization of various shapes, sizes and colors.

[0003] Therefore, our company has developed a method of producing a goods tray by extrusion molding. However, due to the limitations of the structural form and technological process of the extrusion molding die, the existing goods trays cannot meet the technological process of extrusion molding. For example, the prior art discloses a goods tray (authorized publication number: CN 204124505 U), which includes a body and a plurality of independent connecting sleeves fixedly connected to the lower side surface of the body. Since the connecting sleeves are independent individuals, gaps are formed between any two adjacent connecting sleeves in the X-axis direction and the Y-axis direction. In the technological process of extrusion molding, the tray with this structure cannot meet the production requirements, and its body is a single-layer structure, and its load-bearing capacity is limited, and the strength still needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the above background art, and provide an extrusion tray. By arranging a plurality of support components in the horizontal direction, and the support components are arranged in a continuous state in the vertical direction, the structure of the extrusion tray is changed, so that it can better meet the technological requirements of extrusion molding, realize continuous production operations, thereby improving the production efficiency of the tray and reducing the production cost of the tray.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows: An extrusion tray includes a tray bearing plate and a support member disposed at the lower end of the tray bearing plate. The tray bearing plate and the support member are integrally formed. A plurality of the support members are symmetrically arranged in the transverse direction, and a forklift insertion portion is formed between the two support members, which facilitates the fork feet of the forklift to smoothly enter the bottom of the extrusion tray to realize the transportation of goods. Moreover, any one of the support members is continuously arranged in the longitudinal direction, which is beneficial to improving the overall strength of the extrusion tray and also facilitates the implementation of the extrusion molding process.

[0006] The tray bearing plate includes a first hollow grid structure, and the first hollow grid structure can be set into a two-layer structure or a multi-layer structure according to the actual load-bearing strength requirements.

[0007] The support member includes a second hollow grid structure, and the second hollow grid structure can be set into a two-layer structure or a multi-layer structure according to the actual height and strength requirements. The setting of the hollow grid structure makes the extrusion tray have stronger bending resistance, and when achieving the same mechanical effect, the quality of the tray is lighter.

[0008] Preferably, the second hollow grid structure is higher than the first hollow grid structure, which is beneficial to the fork feet of the forklift to smoothly enter the bottom of the extrusion tray to realize the transfer and transportation of goods.

[0009] Furthermore, the second hollow grid structure is in an inverted trapezoid shape, with a larger upper end and a smaller lower end, and has stronger load-bearing capacity.

[0010] Furthermore, a reinforcing steel strip or a fiberglass strip is disposed inside the tray bearing plate by co-extrusion to improve the overall strength of the product.

[0011] Furthermore, the reinforcing steel strip or the fiberglass strip can be arranged at intervals left and right, or at intervals up and down, or the reinforcing steel strip or the fiberglass strip can be arranged in the four directions of up, down, left, and right of the tray bearing plate.

[0012] The beneficial effects of the present utility model are as follows: (1) By arranging a plurality of support members in the transverse direction and the support members being continuously arranged in the longitudinal direction, the structure of the extrusion tray is changed, enabling it to better meet the process requirements of extrusion molding, realizing continuous production operations, thereby improving the production efficiency of the tray and reducing the production cost of the tray; (2) By setting the first hollow grid structure and the second hollow grid structure, the extrusion tray has stronger bending resistance, and when achieving the same mechanical effect, the quality of the tray is lighter; (3) By setting the reinforcing steel strip or the fiberglass strip, the overall strength of the product is further improved.

[0018] The present utility model will now be described in further detail with reference to the drawings. These drawings are all simplified schematic views, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0019] As Figures 1 to 3 shown, an extrusion tray includes a tray bearing plate 001 and a support member 002 disposed at the lower end of the tray bearing plate 001. The tray bearing plate 001 and the support member 002 are integrally formed. Three groups of the support members 002 are symmetrically arranged in the transverse direction. A forklift insertion part 003 is formed between the two support members 002, which facilitates the forklift forks to smoothly enter the bottom of the extrusion tray to realize the transportation of goods. Moreover, any one of the support members 002 is continuously arranged in the longitudinal direction, which is beneficial to improving the overall strength of the extrusion tray and also facilitating the implementation of the extrusion molding process.

[0020] The tray bearing plate 001 includes a first hollow grid structure 004, and the first hollow grid structure 004 can be set into a two-layer structure according to the actual load-bearing strength requirements.

[0021] The support member 002 includes a second hollow grid structure 005, and the second hollow grid structure 005 can also be set into a two-layer structure according to the actual height and strength requirements. The setting of the hollow grid structure makes the extrusion tray have stronger bending resistance, and when achieving the same mechanical effect, the quality of the tray is lighter.

[0022] As Figure 1As shown, the second hollow grid structure 005 is higher than the first hollow grid structure 004, which is conducive to the forklift forks smoothly entering the bottom of the extrusion tray to achieve the transfer and transportation of goods. And the second hollow grid structure 005 is in an inverted trapezoid shape, with a larger upper end and a smaller lower end, and has a stronger bearing capacity.

[0023] As Figure 3 shown, inside the tray bearing plate 001, reinforcing steel strips 006 are arranged at left and right intervals by co-extrusion, thereby improving the overall strength of the tray.

[0024] The production and molding method of this extrusion tray relies on an extrusion die. The extrusion die extrudes molten materials such as PE, PP, or PVC through the extrusion die to form a shape. If it is necessary to further improve the strength, the molten materials can be co-extruded with reinforcing steel strips or glass fibers to achieve continuous production operations. Then, according to the required length, it is cut in the length direction (extrusion direction) to form individual trays, that is, extrusion trays are formed. Since extrusion molding has higher efficiency and lower production costs compared to injection molding and blow molding, it has higher market value.

[0025] Taking the above ideal embodiments based on the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
