Polyurethane foaming mixing head drying mechanism

Abstract

The invention provides a polyurethane foaming mixing head drying mechanism. The polyurethane foaming mixing head drying mechanism comprises a drying base, a supporting table and a heating assembly; a drying groove for containing the lower portion of a polyurethane foaming mixing head is formed in the upper end face of the drying base, a drying hole is formed in the drying base, one end of the drying hole extends to the bottom of the drying groove, the other end of the drying hole communicates with an external air source, the supporting table is arranged in the drying groove, and the upper end face of the supporting table makes contact with the bottom of a mixing core of the polyurethane foaming mixing head. The heating assembly is arranged in the drying groove of the drying base and comprises at least one heating pipe and a plurality of heating supports, and the heating pipes are fixed to the wall of the drying groove through the heating supports. The polyurethane foaming mixing head drying mechanism has the beneficial technical effects that the structure is reasonable, the application is convenient, the drying mechanism is designed for the polyurethane foaming mixing head, moisture residues in the mixing head after cleaning are avoided, and the cleaning efficiency of the polyurethane foaming mixing head can be improved.

Description

technical field [0001] The invention relates to a polyurethane foam mixing head drying mechanism. Background technique [0002] Polyurethane waste regeneration technology completes the regeneration operation by processing polyurethane waste into powder or granules. It is necessary to use a polyurethane foam mixing head to complete the material processing into powder or granules for transportation and spraying. However, due to the polyurethane foam mixing head The mixing core It is a special-shaped structure, and there will be residual material remaining on the mixing core after the polyurethane foam mixing head is sprayed. [0003] The Chinese patent with the application number: CN201910001212.4 discloses a "polyurethane waste regeneration device", which includes a storage tank and a metering mechanism. The outer wall of the storage tank is equipped with a material level sensor, and the inside of the storage tank is provided with a The shaft is sealed, the metering mechanis...

AI Technical Summary

Problems solved by technology

It also discloses that "the inner side of the metering bracket is penetrated with a piston rod, the inside of the piston rod is provided with a solid inlet, the outer middle part of the piston rod is equipped with an oil cylinder, and the upper and lower ends of the oil cylinder are equipped with oil cylinder covers. The middle part of the inner side is equipped with a "cylinder piston" structure. Its main purpose is to extend the mixing core part at the lower end of the mixing head out of the seat for easy cleaning. However, after cleaning, it is necessary to wait for the water on the surface of the mixing head to evaporate completely before spraying the mixture again. Operation, waiting time is too long, affecting production efficiency; and it is easy to cause residual water droplets in the mixing head, affecting the subsequent spraying quality
