In the automated production lines of food factories, central kitchens or large canteens, trays full of food need to run at high speed and smoothly on the conveyor belt, going through multiple links such as linear transmission, turning, climbing, and confluence.In this process, the relative sliding between the tray and the conveyor belt due to inertia, vibration or direction change is an important cause of the tray offset, collision and even spilling food.The design of non-slip shading is an effective solution to this engineering problem.The core principle is to increase the static friction coefficient of the contact surface with the conveyor belt (usually food-grade PU or PVC belt) by designing a specific texture pattern at the bottom of the tray, thereby providing sufficient adhesion to prevent unexpected movement.

The design forms of non-slip shading patterns are diverse, and the common ones are annular radial patterns, wavy patterns, dot matrix projections or cross-mesh patterns.Multiple factors need to be considered in the design: the height and density of the texture need to provide sufficient grip, but not too high and too dense to cause cleaning difficulties or affect the flatness of the tray placement.The direction of the texture is sometimes optimized according to the direction of transportation. For example, a directional texture is designed in the main direction of travel.The coefficient of friction of the material itself (such as PP) is also the basis.In addition, for trays that need to undergo freezing or high temperature environments, it is also necessary to ensure that the shading design will not deform and fail under temperature changes.

A complete set of engineering solutions not only includes shading design, but also needs to be considered in conjunction with the parameters of the conveying system.For example, the material, tension, running speed, and turning radius of the conveyor belt must be designed to match the non-slip performance of the pallet.In practical applications, simulation tests should be carried out to verify whether the pallet can maintain a stable trajectory on the conveyor belt under acceleration, deceleration, emergency stop, turning and slight vibration conditions, without stacking or overturning.For slope sections that need to be climbed, anti-skid requirements are higher, and additional ribs or drive assistance may be required.Investing in scientifically proven non-slip shading trays may be slightly more expensive than flat-bottomed trays, but it can significantly improve the operating stability and reliability of the production line, reduce production interruptions and material waste caused by pauses and cleaning up spills, and ensure the smooth and efficient automated production process. In the long run, it is an important detail to improve the overall equipment comprehensive efficiency (OEE).
