Description

Technical Field

[0001] The utility model relates to the technical field of unloading bottles from a PE bottle bin, and more particularly to a self-service bottle unloading device for a PE bottle bin. Background Art

[0002] PE is a type of plastic raw material. PE bottles are plastic packaging bottles made from polyethylene. After production, PE bottles are stored in a bottle silo. When a PE bottle is used, it is removed from the silo and manually pushed onto a conveyor belt. The conveyor belt then transports the bottle to a bottle unscrambler, which organizes the bottles and moves them to the bottom of the filling equipment for filling. Manually placing the bottles onto the conveyor belt is labor-intensive and requires staff to be stationed near the equipment, making it impractical. Therefore, we have proposed a self-service bottle unloading device for PE bottles. Utility Model Content
