A polyurethane foam machine

Abstract

The invention discloses a polyurethane foaming machine, which comprises a casing, a silo and a driving shaft. A silo is arranged above the casing, and the number of silos is multiple groups. The bottom of the silo is connected with a feed pipe. , the bottom of the feed pipe is communicated with a first pressure pump. According to the density of different raw materials, the present invention can place high-density raw materials in high-position bins through the connection of multiple sets of silos and shells. When raw materials are mixed in an inclined shell, gravity factors can be avoided to cause higher densities. Large raw materials are concentrated under the inner cavity of the shell to prevent uneven mixing of raw materials. At the same time, the inclined shell makes it neither the same nor tangent to the incoming direction of raw materials, which increases the degree of confusion when raw materials enter the shell. The gap between the driving shaft and the driven shaft is large, and the blades have grooves, which increases the throughput of raw materials, improves the distribution and mixing effect of raw materials in the shell, and is beneficial to the mixing of raw materials in the foaming machine. It is suitable for a wide range of promotion and use.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a polyurethane foaming machine. Background technique [0002] Polyurethane is a kind of polymer compound, its full name is polyurethane, and it can be made into polyurethane plastic, polyurethane fiber, polyurethane rubber and elastomer. The device is a kind of foaming equipment that makes the aqueous solution of the foaming agent reach a certain concentration. However, when the existing polyurethane foam machine needs to mix multiple raw materials, the raw materials are often added into the machine together and then stirred. Due to the difference in raw material density, the raw materials with higher density due to gravity may concentrate at the bottom, resulting in uneven raw material mixing. Average, affecting the quality of foamed products. Therefore, we propose a polyurethane foaming machine. Contents of the invention [0003] The object of the present invention is to provide a...
