Halogen semi-white-plated heating tube has unique advantages and important application value in fully automatic bottle blowing machines. The following is a detailed introduction:
I. Heating principle and characteristics
Halogen semi-white-plated heating tube is a semi-white-plated treatment on the basis of ordinary halogen heating tube. Its working principle is similar to that of ordinary halogen heating tube. The filament is heated by electric current, which then excites the halogen elements and reacts chemically with the filament, thereby extending the life of the filament and improving the luminous efficiency. At the same time, halogen elements will generate infrared radiation at high temperatures to achieve heating of objects. The semi-white-plated treatment is to coat part of the surface of the heating tube with a layer of white material. This layer of white material usually has high reflectivity and can change the radiation characteristics and heat distribution of the heating tube.
II. Advantages in fully automatic bottle blowing machines
(I) Efficient heating and rapid heating
Enhanced radiation efficiency: The semi-white-plated part of the halogen semi-white-plated heating tube can more effectively reflect and concentrate the infrared rays emitted by the filament to the part of the bottle blank that needs to be heated, thereby increasing the energy density radiated to the bottle blank, thereby speeding up the heating speed of the bottle blank. Compared with ordinary halogen heating tubes, the heating time of the preform can be shortened by about 20% – 30%, greatly improving the production efficiency of the blow molding machine.
Fast response characteristics: The halogen heating tube itself has a fast thermal response characteristic, and the semi-white coating treatment does not affect this characteristic, but further optimizes the heat transfer. During the heating process of the fully automatic blow molding machine, when the temperature of the preform needs to be quickly increased for the blow molding operation, the halogen semi-white coating heating tube can quickly convert electrical energy into thermal energy and transfer the heat to the preform in a concentrated manner, so that the preform reaches the appropriate temperature required for blowing in a short time.
(II) Accurate temperature control
Improved temperature uniformity: The special structure of the semi-white coating heating tube makes the radiated heat distribution more uniform, which can make the temperature rise of each part of the preform more consistent during the heating process. This is crucial for the blow molding process, because the uniform temperature distribution can ensure that the preform expands uniformly during the blowing process, avoid quality problems such as uneven bottle wall thickness and deformation caused by local temperature differences, and improve the quality stability and consistency of the blow molding products.
Synergy with the control system: Halogen semi-white-plated heating tubes can work well with the temperature control system of the fully automatic bottle blowing machine. By setting multiple temperature sensors in the heating area, the temperature changes of the preforms are monitored in real time, and the signals are fed back to the control system. The control system accurately adjusts the power of the heating tube according to the feedback information, thereby achieving precise control of the preform temperature. The error range can be controlled within a small range to meet the requirements of high-precision bottle blowing process.
