A simple and detailed introduction to the structure of pearl cotton high-pressure foaming machineA simple and detailed introduction to the structure of pearl cotton high-pressure foaming machine:
1、 Feed section, raw materials are fed into extruder by feed section, including bin, screw, barrel, main motor of extruder, etc., and AC motor is connected with server screw according to reducer.
2、 Forming heating section, the basic principle of pearl cotton high-pressure foaming machine forming heating section: this part of the equipment has heating structure and refrigeration equipment, which will slowly reduce the temperature of the melted raw materials until the raw materials are extruded according to the screw, and the product is set up according to the feeding position of butane pump and anti shrinkage agent pump, so that the raw materials will not reverse flow in the opposite direction, so as to ensure the safety of production.
3、 In the melting heating section, the electric heating circle with high equipment power dissolves DPE epoxy resin particles, and pushes the dissolved epoxy resin forward according to the screw.
4、 Part of the tube, part of the melted material after extrusion. As soon as the raw material passes through the die lip, polyurethane foaming begins. The thickness of EPE pearl cotton sheet lies in die lip and traction rate.
5、 The traction roller, which is drawn from the sheet by the shaped drum, shall maintain the balance of traction speed. The traction roller is equipped with a DC variable-frequency variable-speed motor, which is conducive to regulating the traction speed.
6、 Shape the drum according to the centrifugal fan in this part to produce air cooling.
7、 The transposed material preparation roller is equipped with a meter counter to confirm the sheet length. When the roll length is set to 190 °, the second roller just begins to unwind the sheet.
