Title: HEATING LAMP-TUBE FOR BOTTLE BLOWING MACHINE
Abstract:
A heating lamp-tube for a bottle blowing machine comprises a tube body (1). A lamp filament (13) is disposed inside the tube body (1). A cross section of the tube body (1) consists of: an arc curve section (11) facing to a bottle preform (100); a parabola section (12) that is connected to the arc curve section (11) and that is back to the bottle preform (100); a hyperbola section; or an elliptic curve section. The lamp filament (13) is located at the focus of the parabola section (12) and the hyperbola section or the elliptic curve section. A coating layer (2) capable of reflecting light rays is disposed on the surface of the parabola section (12) or the surface of the hyperbola section or the surface of the elliptic curve section respectively. The lamp-tube has a good light ray reflection efficiency and can effectively improve the utilization rate of light energy.
