[Expert] Maintenance items of foam forming machine How to use foam machinery

The foam board production equipment is professionally provided by our company for the majority of consumers. In addition, there are many things to watch for the maintenance of the foam molding machine. Let’s take a look at 'How to use the maintenance of the foam molding machine' 'Foam Machinery'. Foam molding machine is a kind of equipment for processing materials required by the chemical industry such as foam and sponge. At present, the laser machine is mainly used for cutting. Due to the advantages of laser beam fine cutting, such as not easy to deform, smooth cutting, and no edge, it is currently used in various fields. Of course, it is inevitable that there will be failures during the use of the foam cutting machine and need to be overhauled. Now let's talk about the following precautions during overhaul.　　Only personnel who know how to use and operate are allowed to repair machinery or replace components! In order to prevent accidents or damage to the machine, the following principles must be observed during maintenance: 　　1. When a fault occurs, disconnect the power supply to stop the machine; 　　2. When the machine cannot be used normally, check the relevant manuals and use The manual determines the correct measures to be taken; the power supply must be turned off before overhauling or replacing components. 3. The parts (components) removed during the overhaul should be replaced with the same new parts (components) in situ, and the instruments used in the overhaul must be calibrated; 　　 4. It is strictly forbidden to put flammable or metal objects in the electrical cabinet or wiring Inside the box; 　　 5. Regularly check the cables and wires for damage to the foam, and the maintenance of the foam molding machine to prevent leakage or electric shock. More similar articles: A certain amount of foaming agent and water vapor are retained in the pre-expanded beads of the foam machinery and equipment. When they are out of the machine, they will condense into a liquid, and the liquid foaming agent will dissolve into the polystyrene to make the bubbles. The pressure drops quickly, negative pressure (partial vacuum) appears in the bubble, and the beads are very soft and easily deformed. Therefore, when air is sent, try not to make the wind pressure too large. The inner wall of the duct should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid static electricity. For ignition, the transmission speed should not exceed 8m/s to avoid damage to the beads.

Sparking, the transmission speed should not exceed 8m/s to avoid damage to the beads. The beads of the foam mechanical pre-expander are wet. After being discharged from the pre-expander, it absorbs air and suddenly encounters cold, causing the foaming agent in the honeycomb cells to condense and form a negative pressure in the cells, so the beads are in It must be placed for a period of time after the pre-expansion. On the one hand, it is dried, and on the other hand, it is allowed to infiltrate the air to eliminate the negative pressure, so that the internal pressure and external pressure in the cells are balanced, so as to prevent the cells from collapsing and make the beads elastic. How to use foam machinery The process of drying, cooling and stabilizing the cell pressure of the EPS beads just out of the pre-expander is called maturation. Maturation improves the further expansion of the pre-expanded beads during the molding process, the fusion between beads and the elasticity of the beads, which is beneficial to improve the quality of EPS products.
