High frequency medium heating technology of high frequency plastic welding machine is applied to the field of plastic packaging. Its working principle is to use electronic self-excited vibration to generate a high-frequency electric field, which is applied to the electrode. Under the effect of the high-frequency electric field, the molecular structure of the plastic will produce polarization, and generate heat under the pressure to achieve hot melting. After using the high frequency plastic welding machine, what daily maintenance items should be carried out? How to check if the current of the high frequency plastic welding machine is abnormal? Now let's get to know.
1、 Daily maintenance of high frequency plastic welding machine
1. Before stopping the high cycle plastic welding machine, the inside and outside of the machine and its surroundings must be cleaned. The die head and rubber material shall be kept clean, and the ash in the high cycle swinging bucket shall be cleaned.
2. The mechanical moving parts of the high frequency plastic welding machine are filled with lubricating oil. The surface of the steel plate is sprayed with antirust oil to prevent moisture and rust. The machine must turn off the main power supply and air source. Do not place it in a damp place or a sunny place for a long time. Do not place it in a sunny place or a sunless place for a long time.
3. If the high frequency plastic welding machine has been out of service for a long time, due to the cold weather, the electronic tubes of the machine will be preheated for at least 30 minutes before starting up next year, which can extend the life of the high frequency electronic tubes. Before starting up, check the electrical appliances for moisture and moisture, and then dry them with a blower.
2、 Inspection method for normal current of high cycle plastic welding machine
1. Observe whether the electronic tube on the front page lights up.
2. Cut off the air source, start the high-frequency switch and observe whether the pointer of the high-frequency instrument is 0.2A.
3. If the ammeter does not display, you can check whether the door resistance is normal or observe whether the AC contactor is working.
4. If the ammeter has a display and the automatic turntable high-frequency machine is at 0.2A, it can detect whether the mold or capacitor chip is ignited.
5. Whether the welding time indicator can jump according to the adjusted time value.
Thank you for your patient reading. The above is an introduction to the daily maintenance of the high frequency plastic welding machine and the inspection methods for whether the current is normal.
