Abstract

The invention relates to a molding machine for foam of a heat insulation layer of a waste refrigerator, which can extrude powdered polyurethane foam of the heat insulation layer of the waste refrigerator into foam blocks, eliminate the potential safety hazard that the foam is inflammable and easy to dissipate, further overcome the shortcoming that the polyurethane foam occupies too much space due to the light weight and save the cost for logistics and warehousing. The molding machine comprises a frame seat, an extrusion molding machine, a feeding machine and a speed reducer, wherein the speed reducer, the feeding machine and the extrusion molding machine are respectively fixed on the frame seat, a feeding port is arranged on the feeding machine, a spiral conveying rod is arranged in the feeding machine, the extrusion molding machine comprises a bin, an extrusion cavity which is combined by mutually orthogonal rods in three directions is arranged at the lower part of the bin, an X-direction extrusion/discharge rod, a Y-direction extrusion rod and a Z-direction push-pull rod are arranged in three orthogonal directions (namely the X-direction, the Y-direction and the Z-direction) of the extrusion cavity, one end of the spiral conveying rod is connected with the bin, the other end of the spiral conveying rod is connected with the speed reducer, and the X-direction extrusion/discharge rod, the Y-direction extrusion rod and the Z-direction push-pull rod are respectively connected with an X-direction hydraulic cylinder, a Y-direction hydraulic cylinder and a Z-direction hydraulic cylinder.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to the field of recycling and processing of waste household appliances, in particular to a foam molding machine for heat insulation layers of waste refrigerators. Background technique [0002] With the promulgation of the "Regulations on the Administration of Recycling and Disposal of Waste Electrical and Electronic Products" and the continuous promotion of the "old-for-new" policy of household appliances, the dismantling and disposal of waste household appliances has become an emerging industry in my country. Among them, the treatment of discarded refrigerators is different from the dismantling mode of other discarded household appliances, which is mainly based on manual assembly lines and supplemented by mechanical tooling, and adopts the mode of overall crushing and mechanical sorting. Among the constituent materials of the refrigerator, the polyurethane foam filled in the...
