High frequency medium heating equipment is used in the field of plastic bonding, which is called high frequency thermal bonding machine, also called high wave plastic welding machine. This kind of equipment is widely used in the welding process of the carpets of the car and in the production process of the sun shading board. The production process of plastic rubber products, such as inflatable toys, raincoats, shower curtains, sunshade, charge boat, and so on, is also used in large quantities.
For a qualified high-frequency equipment, we must first ensure the safety of the production process and operator, and secondly, ensure the stability of operation and the perfection of function. To do the above, we need to meet the following functions.
1, at present, most of the high frequency equipment now being used in China is not shielded or shielded. Serious electromagnetic pollution can not only cause great harm to the health of the operator. It will also cause serious interference to electronic devices such as communication, navigation, etc. Even damage. At the same time, the stability of the equipment's own work will also have a bad effect. The high frequency equipment that accords with the national standard and has perfect functions shall adopt strict shielding measures, including filtering, bypass, isolation and other measures, so that the high frequency electromagnetic field radiation is far lower than the national standard.
2, our company with most of the equipment adopts PLC control, touch screen display mode. Original power automatic tracking system, digital process parameters setting. Make each piece of work strictly according to the same process parameters. Fully guarantee the consistency of product quality.
The welding process of general equipment with material welding time gradually melted under pressure thin material breakdown capacity decreased, the current rapid increase in the changing time by heating time control is difficult to achieve accurate, then prone to occurred flow or strike fire situation. The automatic tracking system of power can increase the power in the first period of second hours to keep welding, large power, third times the power control in low power state for ignition, which can effectively prevent the phenomenon of breakdown fire strike occurred, to ensure the quality of products from the ignition of the mold damage protection.
3, the fault self diagnosis system has greatly facilitated the maintenance and repair of the equipment.
4, a highly sensitive spark protection system can block the electronic tube in 1/100000 seconds. And the high voltage power supply is cut off in time so that the point of the discharge stroke is just as big as the tip of the needle. This protection device is also applied to the common configuration of the equipment in our company.
