Description

Technical Field

[0001] The utility model relates to the technical field of preform heating equipment, in particular to a lamp tube adjusting mechanism at the bottom of a heating box and a heating box comprising the lamp tube adjusting mechanism at the bottom of the heating box. Background Art

[0002] During the blow molding process, the preform needs to be heated to a highly elastic state (above 67°C and below 245°C) in a crystalline state before compressed air is introduced into the preform cavity to stretch and expand the preform. Figure 1 As shown, it includes a mounting base 1', on which a plurality of lamp tube assemblies 2' are installed at intervals in the vertical direction, wherein the lamp tube assembly 2' at the bottom is tilted and used to heat the arc side surface of the bottle blank 3' close to its bottom, but cannot face the bottom of the bottle blank 3', and the remaining lamp tube assemblies 2' are used to heat the side surface of the bottle blank 3'. The bottle blank heating device has a better heating effect for small-sized and thin bottle blanks.
