How to ensure uniform heating when infrared heating lamps are used in bottle blowing machines?
Reasonable heating lamp layout
Circular distribution: It can ensure that the preform can receive equal amounts of infrared radiation in all directions, thereby achieving uniform heating.
Multi-layer layout: For higher or complex-shaped preforms, a multi-layer Infrared Heating Lamps layout can be adopted. The position and angle of each layer of heating lamps must be precisely designed to ensure that the preform can be evenly heated from top to bottom and from outside to inside.
Optimize heating lamp power and angle
Power adjustment: Adjust the power of each halogen heating bulbs according to the material, size and shape of the preform. . At the same time, it is necessary to ensure the power consistency of each halogen infrared heater lamp to avoid uneven heating caused by power differences.
Angle adjustment: Accurately adjust the irradiation angle of the Infrared quartz heater replacement lamp so that the infrared can irradiate vertically to the key parts of the preform surface.
Rotating device: During the heating process, the preform can be rotated to allow all sides of the preform to receive infrared irradiation evenly.
Movement control: In addition to rotation, the movement of the preform in the heating area is also important. For longer preforms, a uniform linear movement can be used so that each part of the preform can be sufficiently heated when passing through the heating area.
Temperature monitoring and feedback control
Temperature sensor layout: Temperature sensors are reasonably arranged around the preform to monitor the temperature of different parts of the preform in real time. These sensors can be contact (such as thermocouples) or non-contact (such as infrared thermal imagers).
Feedback control system: The temperature data collected by the temperature sensor is fed back to the control system. The control system automatically adjusts the power of the Quartz IR Halogen Heating Bulb, the rotation speed and movement speed of the preform according to the set temperature target and the actual monitored temperature difference.
