Polyurethane mixing device

Abstract

The invention discloses a polyurethane mixing device, The structure of the device comprises a connecting seat; the connecting seat is provided with a motor; the lower end of the connecting seat is provided with a valve seat; a mixing barrel is arranged at the lower end of the valve seat; a discharge hole is arranged at the lower end of the mixing barrel; the connecting seat is internally provided with a connecting shaft; the upper end of the connecting shaft is connected with an output shaft of the motor; the lower end of the connecting shaft passes through the valve seat and is connected with the top of a mixing bar arranged in the mixing barrel; the valve seat is provided with a feeding hole; the feeding hole is communicated with an inner cavity of the mixing barrel; the valve seat is also provided with a water inlet which is also communicated with the inner cavity of the mixing barrel; and a mixing needle is arranged along the double-helix line of the longitudinal direction on the outer wall of the mixing bar. The polyurethane mixing device has the advantages of convenience in cleaning, uniformity in mixing and lighter structure.

Description

technical field [0001] The invention relates to a polyurethane mixing device. Background technique [0002] Polyurethane foam is widely used, and its semi-rigid polyurethane products mainly include steering wheels and automobile dashboards. At present, the foaming method is generally used in the production of polyurethane foam, that is, the raw materials are mixed under high-speed stirring and then foamed. The structure of the traditional polyurethane mixing device includes: a connecting seat, a motor is installed on the connecting seat, a valve seat is arranged at the lower end of the connecting seat, a mixing barrel is arranged at the lower end of the valve seat, and a discharge valve is arranged at the lower end of the mixing barrel. A connecting shaft is arranged in the connecting seat, the upper end of the connecting shaft is connected with the output shaft of the motor, and the lower end of the connecting shaft passes through the valve seat and connects with the top o...

Problems solved by technology

When cleaning, the cleaning agent is introduced from the water inlet, and the cleaning agent enters the inner cavity of the mixing cylinder. However, due to the large contact area between the mixing impeller and the raw materials, there are many raw materials remaining on the mixing impeller after the mixing is completed, and cleaning is very difficult. convenient
