AI Technical Summary
In existing heating devices for blow molding machines, the installation stability of heating lamps is relatively weak, posing a risk of displacement.
The lamp clamp design includes upper and lower clamping plates that work together to hold the heating lamp, and the clamping space is adjusted by the clamping cap. The installation stability is improved by the assembly bolts and positioning grooves, and the heating effect is adjusted by the adjusting rod and positioning bolts.
This design achieves stable installation of the heating lamp, prevents axial movement, improves the overall stability and convenience of the device, and allows for easy adjustment of the distance between the lamp and the preform to change the heating effect.

Abstract
Claims
1. A heating device for a bottle blowing machine, characterized in that: It includes two supporting columns (1) arranged side by side along the preform conveying direction. The upper ends of the two supporting columns (1) are connected to a supporting frame (2). Mounting rods (3) are installed on both sides of the supporting frame (2). Several lamp tube rods (4) are fixedly sleeved on the outside of the mounting rods (3). Each lamp tube rod (4) is provided with a lamp tube clamp (5) at its end. A heating lamp tube (6) arranged along the preform conveying direction is clamped in the lamp tube clamp (5). The lamp clamp (5) includes a connecting piece (51) that is fixed to the end of the lamp support rod (4) by screws, an upper clamping piece (52) fixedly disposed on the upper end of the connecting piece (51), and a lower clamping piece (53) fixedly disposed on the lower end of the connecting piece (51). The upper clamping piece (52) and the lower clamping piece (53) cooperate to press the heating lamp (6) onto the connecting piece (51). The upper clamping piece (52) includes an upper horizontal extension section (521) integrally formed with the connecting piece (51), an upper outer extension section (522) integrally formed with the upper horizontal extension section (521) and extending obliquely upward, and an upper clamping section (523) rotatably connected to the upper outer extension section (522) via a hinge. The upper clamping section (523) is cylindrical. The lower clamping piece (53) includes a lower horizontal extension section (531) integrally formed with the connecting piece (51) and an upper clamping section (523) rotatably connected to the lower outer extension section (522) via a hinge. The flat extension section (531) is integrally formed and extends downward at an inclination. The lower outer extension section (532) is rotatably connected to the lower outer extension section (532) by a hinge. The lower clamping section (533) is provided with a clamping through hole (7) from top to bottom. The upper clamping section (523) passes through the clamping through hole (7). The outer side of the upper clamping section (523) is threaded with a clamping cap (8). The clamping cap (8) abuts against the bottom surface of the lower clamping section (533).
2. A heating device for a bottle blowing machine according to claim 1, characterized in that: The diameter of the upper clamping section (523) is smaller than the width of the clamping through hole (7). When the upper clamping section (523) passes through the clamping through hole (7), buffer gaps are left on both sides of the upper clamping section (523).
3. A heating device for a bottle blowing machine according to claim 1, characterized in that: The end edge of the clamping cap (8) is provided with rounded corners.
4. A heating device for a bottle blowing machine according to claim 1, characterized in that: The lamp tube support rod (4) is threaded with an assembly bolt (9) on its side wall, and the threaded section of the assembly bolt (9) abuts against the side wall of the mounting support rod (3).
5. A heating device for a bottle blowing machine according to claim 4, characterized in that: The mounting rod (3) has a positioning groove (10) on its side wall.
