Stress section based mechanical strength detection device for plastic pallet

Abstract

The invention discloses a stress section based mechanical strength detection device for a plastic pallet. The device structurally comprises four stress detectors, two equipment guide rails, a pressure source and two pallet supports, wherein the pallet supports and the pressure sources are used for simulating the full-load stress condition of the plastic pallet, the stress detectors are mounted on the equipment guide rails, detection arms of the stress detectors form a measurement loop with metal electrodes of stress detection units of key stressed parts of the plastic pallet, structural abnormity or aging degree of the plastic pallet is evaluated through detection of stress deformation, and accordingly, whether the plastic pallet can meet the continuous use requirement is judged. The detection device is high in automation degree and simple to mount and debug, solves the problem about mechanical strength detection of the moving plastic pallet, and has broad market application prospect in the logistic storage and transportation industry requiring a large quantity of plastic pallets.

Description

technical field [0001] The invention relates to a mechanical strength detection device for a plastic pallet based on a stress sheet, in particular to a mechanical strength detection device for applying pressure to a mechanical key part of the plastic pallet, and belongs to the technical field of logistics detection equipment. Background technique [0002] Plastic pallets are the inevitable product of the logistics industry's adaptation to environmental protection requirements and the development of the logistics industry. Using plastic pallets instead of wooden pallets can reduce forest damage. With the continuous strengthening of the concept of food safety, plastic trays are favored by the tobacco industry for their anti-corrosion, moisture-proof, anti-rust, anti-moth, and no mold. [0003] Plastic pallets can be divided into various specifications and sizes according to their shapes. At present, 1100mm×1100mm and 1200mm×1000mm are mainly used, accounting for about 50% of p...

Problems solved by technology

[0008] However, the mechanical strength of plastic pallets cannot be calculated from the measurement results of machine vision. The mechanical strength of plastic pallets needs to be tested under the action of external force to detect the stress change of plastic pallets.
