Analysis of the heating and temperature control system of the blister machine!

The following small series talks about the heating and temperature control system of the blister machine:

In fact, it is just an electric heating box, built-in heating tube, thermocouple, thermostat control, advantages: simple structure, convenient installation, low price, disadvantages: uneven temperature;

Electric heating tube heating, combined step switch cooperates with autotransformer to realize temperature adjustment, adopts autotransformer to step-down temperature adjustment, six-step combination switch adjusts from 120V, 140V, 160V, 180V, 200V, 220V, representative Product, Italian six-speed switch, domestic multi-speed combination switch, advantages: simple adjustment, convenient installation, fast maintenance, disadvantages: small temperature adjustment range;

Heating bricks are heated, the combined step switch is equipped with autotransformer for temperature adjustment, additional ammeter indication, autotransformer is used for step-down temperature adjustment, the six-step combination switch is 120V, 140V, 160V, 180V, 200V , 220V adjustment, with installation ammeter or voltmeter instructions, advantages: simple structure, convenient installation, fast maintenance, disadvantages: small temperature adjustment range;

Heating bricks or heating tubes are used to fine-tune the temperature, using the non-linear characteristics of the thyristor for stepless adjustment from 0 volts to 220 volts, and additional ammeter or voltmeter instructions. Advantages: wide adjustment range, fine-tuning, simple structure, convenient installation, disadvantages: easy to accidentally touch, large temperature display error, high reduction rate;

The heating brick is heated, the temperature is adjusted by pulling out the switch, and the 220 volt voltage is divided into 99 levels adjustment by using the two-position pull-out switch and resistance combination, additional ammeter indication, heating brick heating, integrated temperature controller, digital display, digital display, representative Products: AoYi company products, Nanxing company products, advantages: easy installation, temperature adjustment, simple and intuitive display, disadvantages: can not be combined with the programmable controller system, which is not conducive to equipment intelligence and Internet of Things upgrades;

Heating brick heating, integrated temperature control module temperature adjustment (temperature controller can be used to adjust temperature, can be combined with PLC, touch screen temperature adjustment, can store data, representative products: Aoyi, Nanxing;

Heating brick heating, intelligent temperature control integrated module, programmable controller control, touch screen adjustment, touch screen display, currently mainly products of Guangdong Nanxing Company and Shanghai Zhuanggu Company, Nanxing Company’s product features, integrated intelligent temperature control system, using integrated 12 channels single board independent or combined board but combined, single board 12 channels only use one temperature measurement point, or combine multiple single boards to use one temperature measurement point, and distribute the used humidity to other heating bricks through calculations, one control one Touch screen adjustment, touch screen display, advantages: after temperature adjustment, the furnace temperature will not be affected by the change of the grid voltage, simple installation, fast maintenance, data storage can be realized by PLC combination, which is conducive to the upgrade of equipment in the direction of intelligence, and is conducive to the upgrade of the Internet of Things. Disadvantages: The price is slightly higher and the promotion is not enough. The characteristics of the intelligent temperature control system of Shanghai Zhuanggu Company. Its temperature control method is to collect temperature data, and distribute it to other heating bricks through high-speed calculations. Real-time monitoring, instant compensation, fault diagnosis, can be Combine with PLC to realize data storage, programmable control, programmable control, programmable control, programmable control.

The above is the heating and temperature control system of the blister machine introduced by the editor! I hope to help you understand the simple description and provide reference for the content. For more inquiries, you can always pay attention to the update of our website!
