Case 1: Energy saving upgrade of high-speed beverage bottle production line
A certain bottled water enterprise has one fully automatic bottle blowing line with eight outlets. The original heating system has high energy consumption, uneven bottle wall thickness, a defect rate of about 2%, and high annual electricity pressure.
Solutions:
1. Selection: Infrared Gold Backed Short Wave IR Lamp, single power 1.5-2kW, directional radiation without secondary reflection requirements;
2. Configuration: Multi zone independent temperature control, 6-8 lamps per zone, combined with infrared temperature sensors and PLC dynamic power adjustment;
3. Installation: Horizontal/vertical dual arrangement, with a lamp spacing of 25-35mm, forming a 360 ° air interlayer for heat dissipation.
4. Energy consumption: saving about 15% of electricity costs annually, saving 120kWh of electricity per 10000 bottles, and 120000 kWh of electricity per year when producing 100 million bottles;
5. Quality: The surface temperature difference of the preform has been reduced from ± 5 ℃ to ± 2 ℃, the heating uniformity has been improved, and the defect rate has been reduced from 2% to 1%;
6. Maintenance: The lifespan of the lamp tube has been extended to 8000 hours, a 30% increase compared to traditional products, and the frequency of lamp replacement has been reduced.
Case 2: Cost reduction through the transformation of semi-automatic bottle blowing machine
The old semi-automatic bottle blowing machine (ZQ22-III series) in a certain packaging factory has low heating efficiency, uneven rotation of bottle preforms, limited production capacity, and high scrap rate.
Solutions:
1. Selection: Gold plated reflective infrared lamp tube, supports horizontal/vertical installation, comes with an integrated reflector, simplifies the structure;
2. Renovation: Install 8-12 light tubes on each device, configure an independent temperature control box, adjust the direction of the light tubes to adapt to different bottle preforms;
3. Optimization: Adopting a design of orbital revolution and preform rotation to improve heating uniformity.
4. Production capacity: The hourly output of 600ml bottles per unit has increased from 800 to 1000, with an efficiency increase of 25%;
5. Cost reduction: The number of operators has been reduced from 2 to 1, without the need for special training, resulting in a 35% reduction in maintenance costs;
6. Quality: The scrap rate of finished products is lower than the industry average, and the transparency and strength of the bottle body meet the standards.
