Beverage bottle production line
● Background of the case: A large beverage production enterprise has multiple beverage bottle blowing production lines. In the past, traditional heating methods were used, which had problems such as uneven heating, high energy consumption, and low production efficiency.
● Application effect: After introducing infrared heating lamps, the rapid and uniform heating of bottle preforms is achieved by precisely controlling the wavelength and energy output of the infrared lamp tube, significantly improving the consistency of bottle thickness and enhancing product quality. At the same time, the heating time is shortened, energy consumption is reduced by about 15%, and production efficiency is greatly improved.
When choosing an infrared heating lamp suitable for a bottle blowing machine, the following aspects need to be considered:
Wavelength
● Matching preform material: Different plastic preform materials have different absorption characteristics for infrared radiation. For example, PET plastic bottle preforms usually have good absorption effects in the wavelength range of 1.2 µ m to 1.5 µ m. Choosing an infrared heating lamp in this wavelength range can achieve rapid heating and efficient energy utilization.
● Heating depth requirement: Short wave infrared (0.75-1.4um) has strong penetration power, which can evenly heat the preform from the inside out. It is suitable for the preform preheating and forming stage, such as drying and curing of high-speed printing equipment, plastic blowing and welding, etc.
Power
● Consider the size of the heating area: Select the power based on the size of the heating area of the bottle blowing machine and the number of preforms. The heating area is large and there are many preforms, requiring high-power heating lamps to ensure sufficient heat supply and uniform heating. A large hollow container blowing machine with a large heating area may require a heating lamp of over 3000W.
● Adapt to production speed: With fast production speed, it is required that the heating lamp can provide sufficient heat in a short period of time to reach the appropriate blow molding temperature for the preform. High power heating lamps or multiple sets of heating lamps should be selected for high-speed production lines.
Lamp material
● Quartz glass: It has good transparency and high temperature resistance, can withstand high temperatures without deformation, and can ensure effective transmission of infrared radiation and stable heating. It is a commonly used material for infrared heating lamps.
● Tungsten wire: As a filament material, it has high melting point, high resistance and other characteristics, and can quickly generate heat and infrared radiation after being energized. It has high heating efficiency and can quickly reach the working temperature of the heating lamp.
Reflecting layer
● Enhanced heating effect: Infrared heating lamps with reflective layers can reflect the infrared energy that has not been absorbed by the preform back to the surface of the preform, improving heating efficiency and reducing energy waste. The reflective layer material, such as aluminum alloy or ceramic coating, can achieve a reflectivity of about 95%.
● Optimize heating uniformity: By designing the shape and angle of the reflective layer reasonably, infrared rays can be more evenly irradiated on the preform, avoiding local overheating or insufficient heating, which helps to improve the quality and consistency of the bottle body.
Brand and Quality
● Market reputation: Choosing well-known brands of infrared heating lamps usually ensures better product quality and performance. Brands such as USHIO and Philips have a high level of recognition and good reputation in the bottle blowing machine industry.
● Service life: High quality heating lamps have a long service life, reducing the frequency of equipment downtime and lamp replacement, and lowering maintenance costs. For example, the service life of some light tubes can reach over 5000 hours, which can save more time and costs for enterprises compared to ordinary light tubes.
Control system compatibility
● Adjustable: The heating lamp should be compatible with the control system of the bottle blowing machine to achieve precise power adjustment. This allows for flexible adjustment of heating temperature and time according to different preform materials, specifications, and production process requirements, ensuring the best heating effect for preforms.
● Response speed: The fast response heating lamp can adjust the output power in a timely manner according to the temperature changes of the preform during the production process, improving production efficiency and product quality. For example, some shortwave infrared heating lamps can quickly heat up or cool down within 1-3 seconds, making the heating process control more flexible.
