Description

Technical Field

[0001] The utility model relates to an automatic production line for fiber composite trays, belonging to the technical field of automatic production of fiber composite trays. Background Art

[0002] At present, in the tray processing industry, trays are mostly plastic trays, wooden trays and iron trays. The production equipment for plastic trays is an injection molding machine, and the mold is mostly designed for hot runner, which has high requirements for the melting fluidity of raw materials. Due to the mold, the cooling and forming time of the tray is relatively long, resulting in low production efficiency, high energy consumption and high raw material prices. Correspondingly, the price of plastic trays is relatively high; wooden trays are made of wooden squares, wooden boards or plywood. The raw materials are forest resources. In the main wood development provinces of our country, the logging of natural forests has been explicitly prohibited. Moreover, the assembly and production of wooden trays takes a long time, with low efficiency. It is very difficult to achieve complete uniformity in the size of the trays, which cannot meet the requirements of the automatic packaging line, is easily damaged by moisture, and has low strength. And when conducting foreign trade, fumigation and disinfection treatment are also required; although iron trays have relatively high strength, the welding time is long during production, and anti-corrosion treatments such as painting are required, resulting in low production efficiency.

[0003] Wood-plastic composite materials are a new type of composite materials that have emerged vigorously in recent years at home and abroad. They refer to using polyethylene, polypropylene, polyvinyl chloride, etc. to replace the usual resin adhesives, mixing with waste plant fibers such as wood powder, rice husk, straw, etc. to form a new wood material, and then through plastic processing technologies such as extrusion, molding, and injection molding to produce plates or profiles; mainly used in industries such as building materials, furniture, and logistics packaging.

[0004] In the prior art, there is no complete production line for wood-plastic trays, with low automation and low production efficiency of wood-plastic trays.

[0014] Furthermore, it further includes a bucket elevator and a forced feeder. The bucket elevator transports the material in the high-speed mixer to the forced feeder, and the forced feeder transports the material to the extruder.

[0015] Furthermore, the pallet-taking manipulator stacks the processed pallets on the pallet output device.
