Sponge foaming machine

Abstract

The invention discloses a sponge foaming machine, which comprises a pre-foaming barrel, a water discharge pipe, a fluidized bed, a supporting frame, a feeding device, an infusion pipe, a water tank, afirst feeding hopper, a raw material barrel, a first raw material conveying screw, a weighing device, a second feeding hopper, a base, a second raw material conveying screw. an upper base, a speed reducer, a water pump, a water meter, a rotating shaft, a detector, a switch valve, a feeding pipe, an impeller, a suction hole, a vent hole and a spiral blade, wherein the side wall of the pre-foamingbarrel is fixedly connected with the water discharge pipe; the feeding device is fixedly connected with the side wall of the pre-foaming barrel with respect to the lower part of the water discharge pipe; the side wall of the pre-foaming barrel is fixedly connected with the fluidized bed; the feeding device is arranged inside the fluidized bed; the lower end of the fluidized bed is fixedly connected with the supporting frame; the bottom of the pre-foaming barrel is fixedly connected with the infusion pipe; the other end of the infusion pipe is fixedly connected with the water tank. The machinehas the advantages that the foaming is uniform, the defective rate is reduced, the cleaning is convenient, and the degree of automation is relatively high.

Description

technical field [0001] The invention relates to the technical field of foaming machines, in particular to a sponge foaming machine and its use method. Background technique [0002] Polyurethane soft foam rubber, polyurethane is the most common polymer material in life, widely used in the production of various "sponge" products. And elastic materials for shock absorption and anti-friction purposes, such as shoe soles, tractor tank track substrates. The foaming resin, foaming aid and binder resin (to make the finished product adhesive) are mixed together, and it needs to be foamed with a sponge foaming machine. [0003] However, the current sponge foaming machine has the problems of uneven foaming, high defective rate, inconvenient cleaning, and low degree of automation, and the use method of the current sponge foaming machine is relatively complicated, and it is not easy to master and control. [0004] Therefore need to invent a kind of foaming more evenly, reduce defective...
