Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tray stacking, particularly relates to a wooden tray production stacking mechanism. BACKGROUND

[0002] Wooden tray is a tray made of natural wood, which is the most widely used tray at present. The tray is a horizontal platform device for placing goods and products as unit load for assembly, stacking, handling and transportation. It is usually made of wood, metal or fiberboard, which is convenient for loading and unloading, handling unit materials and small quantities of materials. The main types of trays are wooden, plastic and metal. Wooden tray is the most widely used because of its low price and durability. After production, the tray needs to be manually transported and stacked for storage in the warehouse.

[0003] For example, the patent document with the announcement number CN221875763U discloses a wooden tray production stacking mechanism, which includes a stacking vehicle, a movable block and a protective plate. The stacking vehicle is fixedly installed on the top of a gantry, and a screw rod A is vertically rotatably installed inside the gantry. The movable block is slidingly installed in the gantry, and a screw hole A is vertically formed in the center of the movable block. The screw rod A penetrates the screw hole A and is threadedly engaged with the inner wall of the screw hole A. The movable block is symmetrically fixedly installed with spade teeth on both sides of the front end. The gantry is symmetrically installed with a track A below the front wall on both sides. A screw rod B is horizontally rotatably installed in the track A. The protective plate is provided in two groups. The above-mentioned device can gradually catch the trays on the production line for stacking without manual stacking. After stacking is completed, the trays can be directly transferred, which is more flexible, greatly improves the stacking efficiency and convenience, and provides better protection during stacking to avoid tray tipping and improve safety and reliability. In the prior art, the wooden tray is often stacked irregularly when using the stacking mechanism. The irregular deviation accumulates in the layer-by-layer stacking, which weakens the stability and may cause tipping during transportation. To avoid this problem, a stacking mechanism with a stacking shaping function is proposed. SUMMARY
