Description

Technical Field

[0001] The utility model relates to the technical field of recycled polyester bottle flake production, in particular to a packaging device for recycled polyester bottle flakes. Background Art

[0002] Polyester bottle flakes are 4*5*2 mm flake particles obtained by polymerizing polyester as raw material. The scientific name of polyester bottle flakes is polyethylene terephthalate, which is made by exchanging dimethyl terephthalate with ethylene glycol or esterifying terephthalic acid with ethylene glycol to synthesize dihydroxyethyl terephthalate, and then undergoing a condensation reaction. Polyester bottle flakes are widely used in the production of fibers, packaging materials, films, and engineering plastics. After the corresponding fibers, packaging materials, films, and engineering plastics are recycled, they need to be made into recycled polyester bottle flakes again to facilitate their subsequent production. After the preparation is completed, the recycled polyester bottle flakes need to be packaged and transported.

[0003] Application No. CN202322535148.2 discloses a packaging device for recycled polyester bottle flakes. By arranging a material receiving barrel, a movable plate, a connecting plate and an electric flat car, the problem that particles of recycled polyester bottle flakes are prone to pop out during packaging, causing material waste, and requiring additional cleaning and inconvenience in use is solved. The hanging ears on the recycled polyester bottle flake particle packaging are hung on the hook, and the hydraulic cylinder is started. The hydraulic cylinder drives the hydraulic rod, which drives the hook to drive the recycled polyester bottle flake particle packaging to rise until the movable plate rises to press the push switch on the connecting plate. After the push switch is pressed, the electric control valve is started to guide the recycled polyester bottle flake particles in the material receiving barrel from the output pipe to the recycled polyester bottle flake particle packaging, so that when in use, the recycled polyester bottle flake packaged material is directly guided into the packaging for packaging, which can better prevent particles from popping out and causing material waste during use.
