Raw material pulverizer for polyurethane foam plastic production and pulverizing method

Abstract

The invention discloses a raw material pulverizer for polyurethane foam plastic production and a pulverizing method, and relates to the field of polyurethane foam plastic production. The raw material pulverizer comprises a base, the top of the base is connected with a pulverizing box through a plurality of damping assemblies, and the top of the pulverizing box is fixedly connected with a cutting box through a plurality of stand columns. An L-shaped machine base is fixedly installed on one side of the cutting box, a driving motor is fixedly arranged on one side of the L-shaped machine base, a discharging pipe is fixedly connected to the bottom side of the cutting box, and a control valve is fixedly arranged on the discharging pipe. The raw material pulverizer is reasonable in structure, when the driving motor is started, cutting blades can be driven to rotate for preliminary pretreatment, two crushing tooth rollers can also be driven to rotate oppositely for crushing treatment, meanwhile, a conveying spiral blade can also be driven to rotate to convey unqualified raw materials for repeated crushing again, finally, all the raw materials can be crushed to be qualified, manual screening and investment are not needed any more, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the field of polyurethane foam production, in particular to a raw material pulverizer for polyurethane foam production and a pulverization method. Background technique [0002] Polyurethane foam is made of isocyanate and hydroxyl compound through polymerization and foaming. According to its hardness, it can be divided into two types: soft and hard. It has excellent elasticity, softness, elongation and compressive strength; good chemical stability, resistant to many solvents and oils; excellent wear resistance, 20 times larger than natural sponge; and excellent processability, heat insulation , Adhesive and other properties, it is a kind of cushioning material with excellent performance. In the production of polyurethane foam, it is necessary to use a pulverizer to pulverize the raw materials. [0003] It is difficult for the existing raw material pulverizers for polyurethane foam to pulverize large pieces of raw materials int...

AI Technical Summary

Problems solved by technology

[0003] It is difficult for the existing raw material pulverizers for polyurethane foam to pulverize large pieces of raw materials into the required size at one time. The raw materials that are not completely pulverized need to be re-screened by the staff and put into the pulverizer again for repeated pulverization, increasing It reduces the labor intensity of the staff and is inconvenient for users to use. At the same time, when the pulverizer directly pulverizes large raw materials, it is easy to cause damage to the pulverization gear roller, which reduces the pulverization accuracy and service life of the pulverizer. For this reason, this application discloses A raw material pulverizer for polyurethane foam production is developed to meet people's needs
