Abstract
A continuous mixing feeding device with anti-blocking function comprises an internal tube; a chain extender cavity and a prepolymer cavity are installed on the external wall of the internal tube; the chain extender cavity and the prepolymer cavity are provided with a material inlet, respectively, wherein the internal tube is fixed with the chain extender cavity and the prepolymer cavity via a bearing, respectively; the internal tube is sleeved inside the two cavities; a hole is arranged on the surface of the internal tube in the chain extender cavity; the internal tube is connected with a motor; and a plurality of anti-blocking scraping pieces are arranged on the external wall in the vicinity of an outlet of the internal tube. The continuous mixing feeding device with anti-blocking function uses the motor to enable the hollow anti-blocking scraping pieces to be continuously rotated, so as to effectively avoid blocking the outlet of the mixing feeding device and vortex phenomenon caused by the anti-blocking scraping pieces in the process of rotation. According to the utility model, the sectional areas of the outlets of the internal and external tubes in the mixing feeding device are reduced, thereby largely reducing the possibility for gathering and agglomerating small colloid particles on the section of the outlet of the mixing feeding device. The device has simple structure and long use period and the like.
