Description

Technical Field

[0001] This utility model relates to the field of long glass fiber polypropylene processing technology, specifically a cooling mechanism for a long glass fiber polypropylene extruder. Background Technology

[0002] Long glass fiber polypropylene is a thermoplastic composite material, often composed of polypropylene resin and long glass fibers. The long glass fibers are uniformly dispersed in the polypropylene matrix, thus giving the composite material excellent mechanical properties, such as high strength, high stiffness and good impact resistance. Because long glass fiber polypropylene composites combine the lightweight, chemical resistance and easy processing properties of polypropylene with the high strength and thermal stability of glass fibers, they are very popular in various industrial applications.

[0003] Chinese patent document CN222712807U discloses a cooling mechanism for a long glass fiber polypropylene extruder, including a base and an extruder body mounted on the base. The extruder body includes an extrusion cylinder and multiple supports for supporting the extrusion cylinder. The extrusion cylinder has a feed port and a discharge port. A cooling component is sleeved on the outside of the extrusion cylinder. The cooling component includes multiple mounting plates sleeved on the outside of the extrusion cylinder and multiple connecting rods for connecting the mounting plates. A fan is detachably mounted between two adjacent mounting plates. A turntable is fixedly connected to the middle of the connecting rods. The turntable rotates to drive the cooling component to rotate, thereby cooling the extrusion cylinder from multiple directions. The cooling mechanism for the long glass fiber polypropylene extruder provided by this invention allows the cooling component to slide and rotate on the surface of the extrusion cylinder, reducing the cooling dead angle of the extrusion cylinder and improving the efficiency of the device in cooling the extrusion cylinder.

[0004] The existing technology mentioned above cannot quickly transfer and absorb heat inside the extruder barrel. At the same time, high external temperatures can easily penetrate into the extruder barrel, causing overheating inside the extruder barrel. Therefore, it is necessary to develop a cooling mechanism for long glass fiber polypropylene extruders. Utility Model Content
