The working principle of infrared heating lamps for bottle blowing machines is to use the radiation characteristics of infrared rays to heat the preforms. The specific steps are as follows:
Preheating: The preforms are irradiated by infrared high-temperature lamps to heat and soften the body of the preforms. In order to maintain the shape of the bottle mouth, the mouth of the preform does not need to be heated, so a cooling device is required for cooling.
Bottle blowing: The preforms that have been preheated are placed in the blow mold and inflated with high pressure. Under the action of high-pressure gas, the preforms are blown and stretched into the desired bottle shape.
During the bottle blowing process, the power, temperature and irradiation time of the infrared heating lamps need to be controlled to ensure that the preforms can be evenly heated and softened, and achieve the appropriate bottle blowing effect.
At the same time, it is also necessary to adjust the process parameters of the bottle blowing machine according to different preform materials and shapes, such as stretching speed, pre-blowing time, etc., to ensure the quality and efficiency of bottle blowing.
