500mm 220v 1200w shortwave infrared heat lamps for fully-automatic bottle blowing machine
Halogen infrared heating tubes have many important applications in fully automatic bottle blowing machines. The following is a detailed description:
1. Heating principle and characteristics
Halogen infrared heating tubes use the special reaction of halogen gas (such as iodine or bromine) and tungsten filament at high temperature to achieve efficient heating. Electric current passes through the tungsten filament to make it heat up and generate infrared radiation. The halogen gas circulates in the heating tube, reacts with the evaporated tungsten and re-deposits tungsten on the tungsten filament, extending the life of the tungsten filament while ensuring the stability and continuity of heating. The infrared rays it emits have high energy and good radiation characteristics.
2. Advantages in fully automatic bottle blowing machines
(1) Efficient and fast heating
Fast heating capability: During the start-up phase of the bottle blowing machine, the preform needs to be quickly heated to the appropriate temperature for bottle blowing operation. Halogen infrared heating tubes can quickly convert electrical energy into infrared radiation energy, so that the temperature of the preform rises in a short time. For example, for common PET preforms, the use of halogen infrared heating tubes can heat them to the stretching temperature required for bottle blowing within a few seconds to tens of seconds, greatly improving the production efficiency of the bottle blowing machine.
Efficient energy transfer: Infrared radiation can directly penetrate the surface of the preform and transfer heat to the inside of the preform, making the temperature inside and outside the preform rise evenly. This direct energy transfer method avoids the time delay and energy loss of heat conduction from the outside to the inside in traditional heating methods, ensuring that the preform reaches a uniform stretchable state in a short time.
