Halogen infrared heating tubes play an important role in fully automatic bottle blowing machines and have many advantages. The following is a detailed introduction:
1. Heating principle and characteristics
Heating principle: Halogen infrared heating tubes heat the filament to a high temperature by applying current to the filament. The halogen gas around the filament reacts chemically with the evaporated tungsten to form tungsten halides, which decompose near the filament and are redeposited on the filament, extending the life of the filament. At the same time, the infrared radiation energy generated by the heating of the filament can efficiently heat the preform.
Radiation characteristics: The infrared wavelength range emitted by halogen infrared heating tubes is relatively wide, of which medium-wave infrared accounts for a large proportion. Medium-wave infrared has a strong penetrating ability and can penetrate deep into the interior of the preform, so that the inside and outside of the preform are heated at the same time, and the heating is more uniform and rapid.
2. Advantages in fully automatic bottle blowing machines
(I) Efficient and rapid heating
Rapid heating: Halogen infrared heating tubes have a fast thermal response speed and can convert electrical energy into infrared radiation energy in a short time, so that the preform heats up rapidly. For example, when blowing PET bottles, the use of halogen infrared heating tubes can shorten the preheating time of the bottle blank from tens of seconds in traditional heating methods to more than ten seconds or even shorter, greatly improving the production efficiency of the bottle blowing machine.
Efficient energy transfer: Its infrared radiation can directly act on the bottle blank without the need for conduction through an intermediate medium, reducing heat loss and improving energy transfer efficiency. Compared with the traditional heat conduction heating method, the bottle blank can absorb more effective heat, further accelerating the heating speed of the bottle blank.
(II) Accurate temperature control
Good temperature uniformity: The uniform infrared radiation emitted by the halogen infrared heating tube can ensure that all parts of the bottle blank are heated evenly and the temperature consistency is high. This is crucial for the bottle blowing process, which can effectively avoid quality problems such as uneven bottle wall thickness and deformation caused by excessively high or low local temperature of the bottle blank, and improve the quality stability of the bottle blowing product.
Accurate temperature control capability: The heating tube works well with the temperature control system of the fully automatic bottle blowing machine, and can accurately adjust the heating power according to different bottle blank materials, thicknesses and bottle blowing process requirements to achieve accurate control of the bottle blank temperature. The temperature control accuracy can reach \\u00b11\\u2103 or even higher, meeting the process requirements of high-precision bottle blowing.
(III) Adapt to a variety of preform materials
Strong material compatibility: The fully automatic bottle blowing machine can handle preforms of various materials, such as PET, PC, PP, etc. Halogen infrared heating tubes can flexibly adjust the heating parameters according to the absorption characteristics of infrared rays of different materials to achieve effective heating of preforms of various materials. For example, PET preforms have a better absorption effect on medium-wave infrared rays, while PC preforms need to adjust the wavelength and power of infrared rays appropriately. Halogen infrared heating tubes can meet these requirements well, enhancing the versatility and adaptability of bottle blowing machines.
Flexible process adjustment: During the bottle blowing process, different bottle shapes, specifications and production requirements require different heating processes. Halogen infrared heating tubes can easily achieve various complex heating processes by changing the arrangement of heating tubes and adjusting the distribution of heating power to meet the diverse needs of bottle blowing production.
