Plastic tray

Abstract

The invention relates to a plastic tray. The plastic tray comprises a base plate, a cover plate and wrinkles, wherein a plurality of support pillars and support seats are arranged on the base plate, and the support pillars are arranged at the edge of the base plate; the cover plate is arranged on the base plate through the support pillars; and the wrinkles are arranged on the bearing face of the cover plate, and the side faces of the base plate and the cover plate. According to the plastic tray, the upper surface and the side face of the tray are in wrinkle structures, the strength of the tray can be increased by first wrinkle units arranged on the cover plate, and the bearing capacity of the tray is further improved; and on the one hand, the strength of the tray can be increased by second wrinkle units arranged at the side faces of the base plate and the cover plate, the bearing capacity of the tray is further improved, and on the other hand, a fork hole part of the tray can be protected from being damaged by fork teeth by the second wrinkle units. In addition, fork hole ribs are changed into inclined decussate structures, an external force can be effectively scattered, and the bearing capacity of the tray is further improved. Besides, reinforcing ribs arranged among the support seats and in the support pillars can be similarly used for enhancing the strength of the tray and increasing the weld strength of the tray.

Description

technical field [0001] The invention relates to a plastic tray, especially a plastic tray combining the advantages of vacuum forming trays and injection molding trays. Background technique [0002] At present, with the rapid development of the economy, logistics has become an important part of the production process. Large-scale collaborative production requires the cooperation of efficient logistics, that is, product parts in the production base also need turnover, and in logistics and production turnover A large number of pallets are required to facilitate handling and loading and unloading with a small forklift. In the past, wooden pallets were used, but now plastic pallets are widely used. In order to be able to bear heavier items, plastic pallets are generally thicker, so a larger overall mold needs to be opened. [0003] There are mainly two types of plastic trays on the market, namely vacuum formed (including blow molding and blister) plastic trays and injection mold...

AI Technical Summary

Problems solved by technology

Vacuum formed trays have the characteristics of good toughness, long service life and light weight, but the vacuum formed trays have single functions and low strength

The injection molded tray has the characteristics of high strength, complex structure, and multiple functions, but the molded tray has poor toughness, high quality, and short service life.

The two types of plastic pallets have their own characteristics in terms of structure and function, but they have gradually been unable to meet the higher requirements of the current logistics industry for pallets in all aspects. It is urgent to develop a new pallet to replace the existing two pallets.
