Definitions

  • the invention relates to the field of polystyrene pallets, in particular to a composite ribbed expanded polystyrene pallet and a manufacturing method thereof.
  • pallets are one of the essential transportation tools.
  • the market mainly includes iron pallets, wooden pallets and plastic pallets.
  • the quality of iron pallets is large, which increases the transportation cost; the quality of wooden pallets is small, but it is easy to be wetted by rot and reduce the service life;
  • the quality of the pallet is heavier and costly, and the foam tray is light in weight but the bearing strength is relatively small compared to iron pallets and wooden pallets.
  • the ribbed expanded polystyrene tray of the invention has the advantages of light weight and strong strength due to the inclusion of reinforcing ribs. Therefore, the effect of saving resources and saving logistics costs will be achieved.
  • the technical problem to be solved by the present invention is to provide a composite ribbed expanded polystyrene pallet and a manufacturing method thereof, which are made of polystyrene material as a body material, light in weight, and coated with a high-strength engineering plastic film base.
  • the special production process adds reinforcing ribs to the body, has good load-bearing performance, economical and practical products, and greatly saves logistics costs. It has broad market prospects in the popularization of composite reinforced expanded polystyrene pallets and their manufacturing methods.
  • the present invention provides a composite ribbed expanded polystyrene pallet and a manufacturing method thereof, comprising: a body and a bottom, the bottom cover covering a bottom surface and a side surface of the body, the body
  • the material is expanded polystyrene
  • the body comprises a pallet surface platform and a plurality of support legs, the plurality of support legs are integrally disposed at the bottom of the pallet surface platform, and the interior of the pallet surface platform is arranged in parallel Several a reinforcing rib, wherein the plurality of reinforcing ribs are respectively disposed with respect to the plurality of supporting legs.
  • the shoe includes a side plate and a bottom body that matches the bottom of the pallet platform, and the side plates are respectively disposed inside the side of the body, To prevent liquid from penetrating.
  • the height of the side panels is less than the thickness of the body.
  • the shoe is a high strength engineering plastic film.
  • the plurality of reinforcing ribs are provided with a plurality of process holes.
  • the cross-sections of the plurality of reinforcing ribs are in the shape of a work shape, a T shape or an L shape.
  • the reinforcing ribs are made of engineering plastics.
  • the method for producing the composite ribbed expanded polystyrene pallet comprises the following steps:
  • the plurality of reinforcing ribs in the step (3) are fixed by a rib support frame, one end of the rib support frame is fixed on the punch, and the other end is provided a spring piece abutting the reinforcing rib, the free end of the spring piece is provided with a certain bending, and the spring piece of the rib support frame is inserted into the process hole of the rib during production, and is bent by the same End support Positioning the reinforcing ribs, after the forming is completed, the spring piece of the rib support frame generates an elastic deformation surface, and the embossing ribs are withdrawn from the body and the rib is left in the body The interior of the body.
  • the invention has the beneficial effects that the composite ribbed expanded polystyrene pallet of the invention and the manufacturing method thereof adopt polystyrene material as the body material, light weight, surface coated with high-strength engineering plastic film bottom support and special production process
  • the ribs are added to the body, the bearing performance is good, the product is economical and practical, and the logistics cost is greatly saved.
  • the composite ribbed expanded polystyrene pallet and the manufacturing method thereof have broad market prospects.
  • FIG. 1 is a schematic structural view of a body of a composite ribbed expanded polystyrene pallet of the present invention and a manufacturing method thereof;
