Problems solved by technology

Due to the cumbersome processing technology and high initial investment cost, this pallet rarely appears in the market, and 90% of domestic manufacturers do not have the conditions to process this pallet, and the initial mold investment cost is also relatively expensive. Most manufacturers are not willing to take this risk. risk developing such pallets
The market utilization rate is not high, and this product is basically eliminated

Abstract

The invention relates to a high-strength ultralight tray and a preparation method thereof. The high-strength ultralight tray is subjected to injection molding by thermoplastic composite material; the upper surface of the high-strength ultralight tray is a plane in a hollow structure; cross-shaped grid ribs are arranged in the hollow structure; the side surface and the upper surface of the high-strength ultralight tray are in 90-degree connection; the junction is in fillet transition; the side surface is provided with an opening used for a forklift; the side surfaces are connected at an angle of 90 degrees; the junction is in the fillet transition; the bottom surface is provided with nine footings; one footing is arranged on the center position; and the rest eight footings are evenly distributed around the bottom surface and are connected by connection ribs. The preparation method comprises the following steps of firstly, preparing polyolefin reinforcing material, and then carrying out injection molding to obtain the high-strength ultralight tray. Compared with the prior art, the invention has the advantages of short injection molding period time, high production efficiency and low production cost, and the obtained product has the advantages of light weight, big bearing and relatively long service life.

Description

technical field [0001] The invention relates to a plastic pallet, in particular to a high-strength ultra-light pallet and a preparation method thereof. Background technique [0002] Pallets are mainly used in logistics turnover, production transportation, material storage and other fields, and play a very important role in modern industry and warehousing logistics industry. Traditional pallets are wooden pallets, and metal pallets are used in some fields, but the appearance and cleanliness of wooden pallets need to be improved, and burrs are prone to appear on the corners; for our country with such a low population and forest occupancy rate, wooden pallets are also not conducive to long-term maintenance. develop. With the development of the petroleum industry, various plastic injection trays, plastic blister trays, plastic blow molding trays, core foam composite trays, wood-plastic composite trays and other new trays have also been more and more used. Chinese patent CN1016...
