Mixing head having enhanced mixing performance and discharging device thereof

Abstract

The purpose of the present invention is to provide a mixing head which mixes a plurality of flowing raw materials so as to discharge the same and has enhanced mixing performance so as to more effectively mix the plurality of flowing raw materials, and a discharge device for the same. The mixing head for mixing a plurality of raw materials which are separately supplied so as to discharge the same, according to the present invention, comprises: a mixing member for carrying out a first mixing of the raw materials; a discharge member communicating with the mixing chamber of the mixing member such that the raw materials are introduced into a discharge movement path; a rotation member having a penetrated movement path which functions as a part of the discharge movement path, and which rotates in the state that the central axial line of the penetrated movement path is relative to the central axial line of the discharge movement path such that the rotation member can be inclined at a predetermined angle so as to form a joining section in the discharge movement path; and a driver for driving the rotation member so as to rotate the rotation member.

Description

technical field [0001] The present invention relates to a mixing head and a discharge device thereof for improved mixing performance. In particular, it relates to a mixing head and a discharge device thereof, in which a rotating body forming a part of the flow path is provided in the flow path of the mixing head for discharging mixed raw materials, and the narrow flow section generated by the rotating body obliquely can Allows for good mixing of materials. Background technique [0002] The mixing head is a device that sprays two or more types of raw materials through a high-pressure nozzle and mixes them by impact. It is mainly used in the manufacture of polyurethane foam products. After the high-pressure injection of polyol (Polyol) and isocyanate (Isocyanate) is mixed, the mixed material is injected into the mold. [0003] The raw materials mixed inside the mixing head need to be in a good mixed state in a short period before being discharged. Therefore, many efforts hav...

Problems solved by technology

[0008] However, the structure of the above-mentioned conventional mixing head (1) also cannot realize sufficient and satisfactory mixing (mixing) between the raw materials, thus making the mixing performance of the raw materials homogeneously mixed is the most important factor for determining the quality of the foamed product.
