Description

Vertical corrugated paper backing plate tray

Technical Field

The utility model relates to a goods packing technical field, specifically speaking relates to a paper backing plate tray for commodity circulation storage transportation industry, more specifically says, relates to a but cyclic utilization vertical corrugated paper backing plate tray for transporting polycrystalline silicon bulk.

Background

The polysilicon material is a silicon material which is purified by a series of physical and chemical reactions by taking metal silicon as a raw material to reach a certain purity, can be directly applied to the manufacture of semiconductor elements, and can also be used as a raw material for preparing monocrystalline silicon. The silicon material is hard and brittle in physical quality, is easy to collide with the silicon ingot in the transportation process, causes the surface of the silicon ingot to be scratched or damaged, has higher reject ratio of subsequent products, brings serious loss to production, and more seriously causes personal injury and inevitable certain loss due to sharp corners after being crushed.

Chinese patent publication No. CN207826805U relates to a recyclable paper pallet for transporting polysilicon ingots, which discloses: the paper base plate tray comprises a rectangular base plate, a rectangular frame is bonded around the upper end surface or the upper and lower end surfaces of the base plate, the outer end surface of the frame is flush with the side end surface of the base plate, and the frame comprises two long guard strips and two short guard strips; the silicon ingot frame is characterized in that N long strip-shaped partition plate strips are arranged in the frame in parallel, the partition plate strips are parallel to the short edges of the frame, the two ends of each partition plate strip are abutted to the end faces of the first corner protectors, the N partition plate strips are arranged at equal intervals to divide the inside of the frame into N +1 grooves which are as large as the number of the grooves and used for containing a polysilicon ingot, and four U-shaped corner protectors III are bonded to the peripheries of the substrate and the frame. The base plate and the frame are both made of honeycomb paperboards and the like. Although the paper backing plate tray structure disclosed in the patent has the advantages of ensuring the transportation safety of the polysilicon ingot, being convenient to manufacture and use, low in cost, light in overall weight and recyclable, the substrate, the frame and the partition plate strips are honeycomb paperboards, the substrate is formed by bonding an upper surface paper and a lower surface paper with honeycomb papercores, and the frame and the partition plate strips are formed by bonding the upper surface paper and the lower surface paper with the honeycomb papercores through a U-shaped corner guard cover. The structure manufacturing form adopting the honeycomb structure and adopting glue for bonding not only greatly improves the raw material cost and the processing cost, but also the frame and the partition plate strips are easy to be stripped due to local unsmooth force and the like, and further the paper tray is deformed and damaged.
