A foamed plastic tray coated with wear-resistant coating

Abstract

The invention discloses a foamed plastic tray coated with a wear-resistant coating, and belongs to the technical field of airport luggage conveying equipment. The foamed plastic tray comprises a corepart and the surface wear-resistant coating, wherein the core part is made of foamed plastic; the outer side of the core part is coated with the surface wear-resistant coating; a chip is arranged in the core part, the core part is provided with a chip fixing structure; and V-shaped stacking structures are arranged at the two ends of the tray. According to the foamed plastic tray, the core part adopts the foamed plastic as a body, the core part material comprises but is not limited to foamed hard PU, foamed PP, foamed PVC, EPP and other foamed plastic, then the wear-resistant coating is sprayedon the surface, the surface wear-resistant coating material comprises but is not limited to polyurea coating, wear-resistant polyurethane and the like, so that the wear resistance of the luggage trayis improved; and compared with the prior art, the overall weight of the tray is reduced, the wear resistance of the tray in the high-speed movement process is improved, the side surface of the tray is prevented from being worn or even broken, and the service life of the tray is prolonged.

Description

technical field [0001] The invention belongs to the technical field of airport baggage conveying equipment, and in particular relates to a foamed plastic tray coated with a wear-resistant coating. Background technique [0002] According to relevant research, in order to realize the rapid passage of passengers at the airport and expand the airport's passenger transportation capacity, it is necessary to realize efficient and dense storage and high-speed long-distance transportation of baggage checked by airport passengers with characteristics such as diversity, non-standardization, and non-standardization. For this reason, a luggage sorting system based on double narrow belt high-speed conveying has been developed. In this system, all checked luggage is placed in a unified container—the tray. The system only needs to drive the tray to complete the transportation and sorting of luggage. Picking, so that the effective protection of luggage can be achieved. [0003] The current ...

AI Technical Summary

Problems solved by technology

The main problems are that the operation is not stable, resulting in high noise, insufficient wear resistance during high-speed conveying, and low pallet strength and poor impact resistance. For example, the Chinese patent No. CN205169148U discloses a kind of automatic logistics with electronic tags. The plastic tray includes an outer shell and an inner filling body, and its manufacturing process is to inject the inner filling body after the plastic outer shell is formed; it has the following disadvantages: it adopts integral hollow molding, and it is difficult to add reinforcing ribs inside the tray according to the current technology, so the tray after molding Due to stress, environment, etc., the deformation of the pallet is relatively serious, and the result is that the pallet is prone to jumping during operation, especially in non-belt transmission areas, such as turning and diversion sections, and foaming during the secondary injection molding of the pallet The high temperature generated by the chemical reaction of the material is also easy to deform the outer shell of the tray. If there is a cavity inside, it is easy to make the center of gravity of the tray deviate, and the stability of the tray will be reduced. loose

According to the test, the surface of the pallet is rapidly worn when the pallet is transported at a speed greater than 7m / s. When the pallet hits the side of the track, the side of the pallet is worn or even broken. At the same time, the surface in contact with the luggage becomes rough after being scratched by the luggage, which affects the sorting of the luggage.
