Tray

Abstract

The invention discloses a tray. The tray comprises a top plate, a bottom plate and upright columns, wherein the top plate, the upright columns and the bottom plate are connected in sequence from top to bottom; and the top plate is provided with an upper plate body and a lower plate body which are connected with each other, and / or the bottom plate is provided with an upper plate body and a lower plate body which are connected with each other. The tray is low in cost and convenient to maintain.

Description

technical field [0001] The invention relates to a logistics appliance, in particular to a pallet. Background technique [0002] At present, pallets generally have wooden pallets and plastic pallets. According to the production method, plastic trays can be basically divided into the following categories: injection molding trays, blow molding trays, single-layer blister molding trays, double-layer blister molding trays, injection molding trays, and rotational molding trays. However, there are basically some shortcomings in different environments, cargo requirements, transportation and handling and other working conditions in the market: [0003] 1. The disadvantages of injection molded trays are: short service life, poor impact resistance, heavy tray weight, poor anti-skid and brittle materials in low-temperature cold storage, etc. Most of them cannot be repaired. [0004] 2. The disadvantages of blow molding pallets are: the pallet loading strength is generally not high, an...

AI Technical Summary

Problems solved by technology

[0003] 1. The disadvantages of injection molding trays are: short service life, poor impact resistance, heavy tray weight, poor anti-skid and brittle materials in low-temperature cold storage, etc. Most of them cannot be repaired

[0004] 2. The disadvantages of blow molding trays are: the loading strength of the trays is generally not high, and they cannot be put on the shelves. When the load is high, the local compression resistance is poor, the anti-skid is not good, and it cannot be repaired.

[0005] 3. The disadvantages of single-layer blister forming trays are: the strength of the tray is generally not high, and it cannot be put on the shelf. When the load is high, the local compressive capacity is poor, the anti-skid is not good, and it cannot be repaired. There are many groove structures on the surface, which cannot be used for sanitation, The surface requirements are flat and other requirements for goods

[0006] 4. The disadvantages of double-layer plastic forming trays are: when the hollow structure is under high load, the local compressive capacity is poor (static load), the anti-slip is not good, and it cannot be repaired; due to technological reasons, it is not possible to make a tray with a complex structure. uneven wall thickness

[0007] 5. The disadvantages of injection molded trays are: solid structure, heavy tray weight, poor anti-skid, no maintenance, low output, high product cost

[0008] 6. The disadvantages of rotomolding are: the pallet loading strength is generally not high, and it cannot be put on the shelf. When the load is high, the local compressive capacity is poor, the anti-skid is not good, the output is low, and it cannot be repaired.
