Sponge foaming method

Abstract

The invention discloses a sponge foaming method. The sponge foaming method comprises a pre-foaming barrel, a drainage pipe, a fluidized bed, a supporting frame, a material conveying device, a liquid conveying pipe, a water tank, a first material conveying hopper, a raw material barrel, a first raw material conveying screw rod, a weight-measuring device, a second material conveying hopper, a base,a second raw material conveying screw rod, an upper base, a speed reducer, a water pump, a water meter, a rotary shaft, a detector, a switch valve, a material conveying pipe, an impeller, air suctionholes, air exhausting holes and a spiral blade; the side wall of the pre-foaming barrel is fixedly connected with the drainage pipe; the lower portion, which is relative to the drainage pipe, of the side wall of the pre-foaming barrel is fixedly connected with the material conveying device; the side wall of the pre-foaming barrel is fixedly connected with the fluidized bed and the material conveying device is arranged in 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 liquidconveying pipe and the other end of the liquid conveying pipe is fixedly connected with the water tank. The method has the beneficial effects that the foam can be relatively even, the defective percentage can be reduced, the cleaning can be relatively convenient and the degree of automation can be relatively high.

Description

technical field [0001] The invention relates to the technical field of foaming machines, in particular to a sponge foaming method and its use. 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 rate, c...
