Bulb sealing machine for mercury thermometer production

Abstract

The invention discloses a bulb sealing machine for mercury thermometer production, which comprises a workbench and a servo motor, and the bottom of the workbench is fixedly connected with symmetrically distributed support legs. By means of the first conveying wheels which are distributed in a staggered mode and the first containing groove in the surface of the first conveying wheels, the thermometer body placed in the first containing groove can evenly pass through the first firing part and the second firing part to be effectively fired, excessive firing cannot be caused, and a large number ofwaste products cannot be generated; the stretching device can be used for effectively stretching the heated thermometer and effectively extruding glass burrs at two ends of the thermometer, so that auser can be effectively prevented from being scratched by edge burrs; the crushing knife arranged in the middle of the first conveying wheel can rapidly crush the stretched thermometers, it can be accurately guaranteed that the lengths of the thermometers on the two sides are roughly the same in the crushing process, and the thermometers subjected to high temperature can be crushed more easily.

Description

technical field [0001] The invention relates to the technical field of thermometer production, in particular to a bubble sealing machine for mercury thermometer production. Background technique [0002] Mercury thermometer, a type of thermometer, is made of glass and contains a column of mercury that rises with body temperature. Mercury thermometers are widely used in the medical field and ordinary households, and some pharmacies can buy mercury thermometers. [0003] Mercury thermometers need to be sealed in the manufacturing process, but the current sealing process is mostly done manually, resulting in uncertain sealing positions, and the sealing positions of each mercury thermometer are not the same, and It is difficult to grasp the heating time of sealing bubbles in the process of heating and sealing bubbles, which greatly increases the reject rate in the process of sealing bubbles. Therefore, we propose a sealing machine for the production of mercury thermometers. Co...
