Advantages of infrared heating tubes in fully automatic bottle blowing machines
(I) Efficient and fast heating
Fast 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 preforms can be heated quickly. For example, when blowing PET bottles, the use of halogen infrared heating tubes can shorten the preform preheating time 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 energy acts directly on the preform without the need for conduction through an intermediate medium, reducing heat loss and improving energy transfer efficiency. Compared with traditional heat conduction heating methods, the preform can absorb more effective heat, further accelerating the heating speed of the preform.
(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 preform 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 temperatures of the preform, and improve the quality stability of the bottle blowing products.
Precise temperature control capability: The heating tube works well with the temperature control system of the fully automatic bottle blowing machine. It can accurately adjust the heating power according to different preform materials, thicknesses and bottle blowing process requirements, and realize precise control of the preform temperature. The temperature control accuracy can reach ±1℃ 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 heating parameters according to the absorption characteristics of infrared rays of different materials, so as 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 appropriately adjust the wavelength and power of infrared rays. Halogen infrared heating tubes can meet these requirements well, enhancing the versatility and adaptability of the bottle blowing machine.
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 realize various complex heating processes by changing the arrangement of the heating tubes, adjusting the heating power distribution, etc., to meet the diverse needs of bottle blowing production.
