一种吹瓶机用加热结构

Abstract

本实用新型提供了一种吹瓶机用加热结构，包括两根支撑立柱，两根支撑立柱的上端共同连接有支撑框架，支撑框架的两侧均安装有安装支杆，安装支杆的外侧固定套设有若干灯管支杆，每一灯管支杆的端部均设置有灯管夹，灯管夹中夹紧安装有加热灯管；灯管夹包括通过螺钉压紧固定在灯管支杆端部的连接片、设置在连接片上下两端的夹片，夹片的中部向外凸起并形成夹持段；夹持段由上至下贯穿设置有腰型通孔，两腰型通孔之间穿设有限位支杆，限位支杆的两端均螺纹连接有限位螺母，限位螺母与夹持段的外壁相抵紧。限位支杆与夹持段靠近连接片的挡肩相配合，可用以限制加热灯管沿灯管支杆轴向的移动，使得加热灯管具有安装稳定性较强的优势。

A limiting support rod (8) is provided between the two waist-shaped through holes (7). The limiting support rod (8) is used to drive the heating lamp tube (6) to abut against the shoulder of the clamping section (521) near the connecting piece (51). Both ends of the limiting support rod (8) are threaded with limiting nuts (9). The limiting nuts (9) abut against the outer wall of the clamping section (521).

2. The heating structure for a bottle blowing machine according to claim 1, characterized in that: The limiting support rod (8) is provided with two positioning protrusions (10) near the heating lamp tube (6). The two positioning protrusions (10) are symmetrically distributed vertically with the heating lamp tube (6) as the center of symmetry, and both positioning protrusions (10) abut against the outer wall of the heating lamp tube (6).

3. The heating structure for a bottle blowing machine according to claim 2, characterized in that: The positioning protrusion (10) is conical, with its small end facing the heating lamp tube (6) and having a hemispherical buffer surface.

4. The heating structure for a bottle blowing machine according to claim 2, characterized in that: A connecting through hole (11) is provided at the position opposite to the positioning protrusion (10) of the limiting support rod (8). The central axis of the connecting through hole (11) is perpendicular to the central axis of the limiting support rod (8). A connecting support rod (12) is provided at the end of the positioning protrusion (10) away from the heating lamp tube (6). The connecting support rod (12) passes through the connecting through hole (11). A connecting nut (13) is threaded to the end of the connecting support rod (12). The connecting nut (13) abuts against the side wall of the limiting support rod (8).

5. The heating structure for a blow molding machine according to claim 1, characterized in that: The lamp tube support rod (4) is threaded with an assembly bolt (14) on its side wall, and the threaded section of the assembly bolt (14) abuts against the side wall of the mounting support rod (3).

6. A heating structure for a bottle blowing machine according to claim 5, characterized in that: A positioning groove (15) is provided on the side wall of the mounting support rod (3). The positioning groove (15) is arranged along the axial direction of the mounting support rod (3). The threaded section of the mounting bolt (14) extends into the positioning groove (15).

7. The heating structure for a bottle blowing machine according to claim 6, characterized in that: The lamp support rod (4) includes an adjusting seat (41) and an adjusting rod (42). The adjusting seat (41) is fixedly connected to the mounting support rod (3) via the mounting bolt (14). The adjusting seat (41) has an adjusting through hole (16) perpendicular to the bottle preform conveying direction. The adjusting rod (42) is slidably disposed in the adjusting through hole (16). A positioning bolt (17) is threadedly connected to the side wall of the adjusting seat (41). The threaded section of the positioning bolt (17) abuts against the side wall of the adjusting rod (42).

8. The heating structure for a bottle blowing machine according to claim 7, characterized in that: A positioning plane (18) is provided on the side wall of the adjusting rod (42).
