Intelligent small-capacity ampoule bottle heat sealing machine special for laboratory

Abstract

The invention discloses a laboratory special intelligent small-capacity ampoule bottle melting sealing machine which comprises a melting sealing table and a supporting platform arranged on the upper portion of the melting sealing table, the upper portion of the melting sealing table is connected with an air injection base through a supporting base, and the air injection base comprises a base body, a first cavity and a second cavity, a through first connecting hole is formed between the first cavity and the second cavity, a sealing unit is arranged in the first cavity, a driving unit is arranged in the second cavity and comprises an electromagnet distributed at the bottom of the second cavity and a moving part arranged in the second cavity, and a metal sheet matched with the electromagnet is arranged on the side, opposite to the electromagnet, of the moving part; and the sealing unit is connected with the moving part, so that the sealing unit moves up and down through the movement of the moving part. The sealing device is good in sealing performance and stable in gas outlet, so that the stability of combustion flames is improved, and the sealing quality of ampoule bottles is improved.

Description

technical field [0001] The invention relates to an ampoule bottle fusion sealing technology, in particular to a laboratory-specific intelligent small-capacity ampoule bottle fusion sealing machine. Background technique [0002] Injections are one of the common dosage forms of pharmaceutical preparations, among which small-volume water injections are the most common. The preparation process includes key steps such as liquid medicine preparation, filling and sealing of ampoules, and sterilization and leak detection. Each step needs to be carried out in the laboratory. Tests have shown that small-capacity ampoule fusion sealing requires a fusion sealing machine. Because the currently used ampoule fusion sealing machine mixes liquefied gas and compressed air in a certain proportion to generate flames, the glass ampoule is calcined and sealed. The air intake is through Ordinary rotary switch control, if the time is too long, it will often cause the outlet flow to fluctuate, and e...

[0002] Injections are one of the common dosage forms of pharmaceutical preparations, among which small-volume water injections are the most common. The preparation process includes key steps such as liquid medicine preparation, filling and sealing of ampoules, and sterilization and leak detection. Each step needs to be carried out in the laboratory. The test proves that the small-capacity ampoule fusion seal requires a fusion sealing machine. Because the currently used ampoule fusion sealing machine mixes liquefied gas and air compressed gas in a certain proportion to generate flames, the glass ampoule is calcined and sealed, and the air intake is through Ordinary rotary switch control, if the time is too long, it often causes the outlet air flow to fluctuate, and even automatically loosen and leak, causing the flame to be too large or extinguished. At the same time, the flame temperature is not up to standard, and there is a risk of air leakage. This leads to uneven sealing of ampoules, unqualified phenomena such as burnt head and tilted head. In addition, because the ampoule fusion sealing machine does not have a glass ampoule bottle placement table, the drawing and sealing positions of each person are inconsistent when sealing, which in turn leads to inconsistent lengths of glass ampoule seals.
