Problems solved by technology

Due to the special structure and limited by the molding conditions of glass products, my country is currently unable to produce glass syringes for prefilled syringes by itself, so that all the more than 30 filling production lines introduced in my country rely on the import of prefilled syringes from European countries, which greatly limits The development of my country's pharmaceutical industry has caused a large outflow of funds, and the localization of prefilled syringes is imminent

Abstract

The invention relates to a glass syringe molding machine for prefilled syringes, which is used for molding glass syringes for prefilled syringes. It has a frame, a molding mechanism and a transmission mechanism, and is characterized in that it includes a glass tube input mechanism and a head molding mechanism , Tail flanging mechanism and annealing mechanism, and a glass tube conveying mechanism is arranged between each mechanism. The molding of the glass syringe of the prefilled syringe is realized, and the structure is compact, automatic operation can be realized, the manufacturing cost is low, the production efficiency is high, and the working environment is good. The invention is successfully developed, realizes the localized production of the prefilled syringe, saves funds, promotes the development of the pharmaceutical industry, and has remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a glass syringe molding machine for pre-filling and sealing syringes, which is used for molding the glass syringes of pre-filling and sealing syringes. Background technique [0002] The development of syringes to this day has undergone major changes, and there are three generations of products. The first generation product is an all-glass syringe, the second generation is a disposable plastic syringe, and the third generation is a prefilled syringe. The prefilled syringe is a syringe that doubles as a drug package, also known as a drug solution packaging container with an injection needle. It is to directly pack the drug solution, especially some precious drug solutions, into the syringe, and inject it directly when using it, avoiding the operation of mixing the drug. loss of liquid medicine and secondary pollution. Plastic cannot be stored in contact with the liquid medicine for a long time, so plastic syringes do not meet t...
