Abstract
The utility model relates to a mixing and sealing device of a polyurethane pouring nose, mainly solving the problems of poorer sealing performance, easiness of abrasion and service life shortening of the traditional polyurethane pouring nose sealing device. The nose comprises a stirring shaft, wherein the periphery of the stirring shaft is fixed with a sealing sleeve, and the lower end of the sealing sleeve is fixed with a moving sealing ring; and a static sealing ring forming a moving sealing fit with the moving sealing ring is fixed in an inner cavity of a nose square. According to the mixing and sealing device, because the sealing structure of the moving ring and the static ring is adopted by the mixing and sealing device of the polyurethane pouring nose, the sealing performance is good; and the sealing structure has the advantages of difficult abrasion, so that the sealing effectiveness is guaranteed, the condition of sealing leakage is prevented, and the service life of the product is effectively avoided being shortened due to the problem of poor sealing performance.
