Technical Field

The invention belongs to the technical field of airport luggage conveying equipment, and particularly relates to a foamed plastic tray coated with a wear-resistant coating.

Background

According to the relevant research, the rapid passage of airport passengers and the expansion of the passenger transportation capacity of airports are required to realize the efficient intensive storage and the high-speed remote transportation of the luggage which is consigned by the airport passengers and has the characteristics of diversity, non-standardization and the like. Therefore, a luggage sorting system based on double narrow belts high-speed conveying is developed, all checked luggage in the system is placed in a uniform container, namely a tray, and the system only needs to drive the tray to finish the transportation and sorting of the luggage, so that the effective protection of the luggage can be realized.

The existing traditional pallet is manufactured by injection molding, rotational molding, blow molding, high-temperature fusion molding of plastic foaming particles and the like, and the common materials are as follows: PP, ABS, PC, PA, EPP and other plastics. The tray is generally constructed as follows: 1. connecting after layered manufacturing; 2. filling foaming material after hollow integral forming; 3. the plastic foaming particles are integrally pressed and molded. The main problems are that the operation is unstable, which causes large noise, the anti-abrasion ability is insufficient in the high-speed conveying process, and the impact resistance is poor, for example, Chinese patent with the patent number of CN205169148U discloses an automatic logistics plastic tray with an electronic label, which comprises a shell and an inner filling body, wherein the manufacturing process comprises the steps of injection molding the plastic shell and then injecting the inner filling body; it has the following disadvantages: the tray is integrally hollow-formed, reinforcing ribs are difficult to increase in the tray according to the prior art, so that the deformation of the tray is serious due to stress, environment and the like after the tray is formed, the tray is easy to jump during operation, particularly in a non-belt transmission area such as a turning section and a shunting section, in the secondary injection molding and filling process of the tray, the shell of the tray is easy to deform due to high temperature generated by chemical reaction of a foaming material, if a cavity is formed in the tray, the gravity center of the tray is easy to deviate, and the operation stability of the tray is reduced; the electronic tag clamping sleeve is connected to the bottom of the tray through screws in a chained mode, and the screws can be easily loosened due to long-term vibration of the tray.

For example, chinese patent No. CN105705423U discloses a pallet for transporting luggage, which is formed by heating, foaming and molding beads of foamed polypropylene in a mold to form a solid integrally molded pallet, the interior of the particles of the foamed polypropylene is foamed by air, and the particles are fused together by the surface, which results in a reduction in the attraction force between the material molecules. According to the test, the surface of the conveying tray is worn sharply at the speed of more than 7m/s, the side surface of the conveying tray is worn and even cracked when the conveying tray impacts with the side surface of the track, and meanwhile, the surface contacting with the luggage is rough after being scratched by the luggage, so that the sorting of the luggage is influenced.

Disclosure of Invention

The invention aims to: in order to solve the defects, a foamed plastic tray coated with a wear-resistant coating is provided, and relates to a luggage conveying appliance. The production process of the appliance is that the core part adopts foamed plastic as a body, and then the surface is sprayed with the wear-resistant coating.

The technical scheme adopted by the invention is as follows:

the utility model provides a coating wear-resisting coating's foamed plastic tray, includes core and surperficial wear-resisting coating, the core is made by foamed plastic, and the surperficial wear-resisting coating is scribbled to the core outside, and the core is inside to be provided with the chip, is provided with chip fixed knot on the core and constructs, the tray both ends are provided with V type stacked structure.

Further preferred in the present invention, the core material includes but is not limited to foamed rigid PU, foamed PP, foamed PVC, EPP and other rigid foamed plastics.

Further preferred in the present invention, the surface wear-resistant coating material includes, but is not limited to, polyurea paint, wear-resistant polyurethane, and the like.

According to a further preferred embodiment of the present invention, the chips are symmetrically arranged on the core portion in a left-right manner, the chip fixing structure includes an installation groove, fixing protrusions and a jacking groove, the chips are installed in the installation groove, the fixing protrusions are symmetrically arranged and clamped in the middle of the chips, the fixing protrusions are fixed in the installation groove, the jacking groove is arranged at the lower end of the chip, and the jacking groove is arranged on the core portion.

In a further preferred embodiment of the present invention, the contact portion of the lifting groove and the chip is an arc portion fitted with the chip.

According to a further preferred embodiment of the present invention, the V-shaped stacking structure includes V-shaped grooves and V-shaped protrusions disposed on two sides of the tray, the upper side of the tray is recessed inwards to form the V-shaped groove, and the lower side of the adjacent tray is recessed downwards to form the V-shaped protrusion matching with the V-shaped groove.

In a further preferred embodiment of the present invention, the core is provided with a reinforcing rib on the luggage surface.

A method for manufacturing a foamed plastic tray coated with a wear-resistant coating adopts foamed plastic as a body, and the wear-resistant coating is sprayed on the surface of the foamed plastic.
