Problems solved by technology
[0004] Among them, the twin-screw extruder generally directly enters the inside of the extruder when feeding, and heats and extrudes inside the extruder, without the process of material premixing and preheating, and the materials are not fully mixed. , leading to poor quality of fiber-reinforced thermoplastics, and at the same time, the feeding control device of some existing twin-screw extruders does not have the function of fixing the controller, and the heat dissipation effect is not ideal

The feeding control device comprises a mounting box, an extrusion box is arranged at the top of the mounting box, a feeding box is arranged on the upper surface of the extrusion box, a feeding port is formed in the top of the feeding box, a top plate is arranged at the top of the feeding box, and a feeding port is formed in the top of the top plate. A motor box is arranged on the side face of the feeding box, a second motor is arranged in the motor box, a crushing wheel is arranged at the top of an output shaft of the second motor and located in the feeding box, and a melting bin is arranged at the bottom of the feeding box and is obliquely arranged. By arranging a series of structures, fiber reinforced thermoplastic plastic raw materials can be crushed, the size of the raw materials is reduced, fusion among the raw materials is more sufficient, the product quality is improved, meanwhile, the fixing effect and the heat dissipation effect of the control box are improved, dust is isolated, the interior of the device is protected against dust influences, and the service life of the device is prolonged. The service life is prolonged.
Description
technical field [0001] The invention relates to the technical field of injection molding, in particular to a feeding control device of a fiber-reinforced thermoplastic twin-screw extruder. Background technique [0002] Fiber-reinforced thermoplastics are reinforced modified plastics prepared by reinforcing fibers. Compared with ordinary plastics, the mechanical properties and heat resistance of fiber-reinforced thermoplastics are greatly improved, and in some aspects, they reach or exceed the performance of metal materials. , The production method of fiber-reinforced thermoplastics is mainly processed by screw extrusion. [0003] The existing screw extrusion devices mainly include single screw extruder, twin screw extruder, multi-screw extruder and planetary screw extruder. Twin screw extrusion processing. [0004] Among them, the twin-screw extruder generally enters directly into the extruder when feeding, and heats and extrudes inside the extruder, which eliminates the p...
