Embodiment Construction

[0037] The present invention will be further described below in conjunction with embodiment:

[0038] Such as Figure 1-12 Shown, the plastic medicine bottle prefilling needle continuous production technique of the present invention comprises the following steps:

[0039] ①Tube embryo extrusion: Extruder 2 carries out vacuum feeding through vacuum feeder 1, and the plastic particles are transported from the plastic particle temporary storage room to the plastic particle hopper of extruder 2 through the action of vacuum; extruder 2 It is mainly composed of plastic granule hopper, extruder driving mechanism (driven by hydraulic motor, variable frequency motor, servo motor or constant torque motor, etc.), extruder screw, heating system, water cooling system, pressure detection system, die head system, and corresponding The wall thickness control system consists of the extruder 2 heating and melting the plastic particles, driven by the extruder drive mechanism and the plasticizat...

Abstract

The invention belongs to the technical field of pharmaceutical equipment, and particularly relates to a needle pre-filling continuous production process for plastic medicine bottles. The process comprises the following steps of (1) tube blank extrusion, (2) tube blank transfer, (3) needle adding and bottle making, (4) filling, (5) injector piston adding and sealing, and (6) blanking. The needle pre-filling continuous production process for the plastic medicine bottles is a whole systematic process and covers a process from raw material conveying to final product conveying, compared with a traditional BFS process, a packaging process is characterized in that an injection needle adding station and an injector piston adding station are added and A-level air shower protection is added in a whole transferring process, functions of equipment are greatly increased, the quality of produced products is higher, the sterile safety of the products is better, and the problem of pollution possibly existing in a process from production to injection of medicines is fundamentally solved.

Description

technical field [0001] The invention relates to a continuous production process of plastic medicine bottle prefilled needles, belonging to the technical field of pharmaceutical equipment. Background technique [0002] The production of plastic medicine bottles by conventional BFS equipment includes extrusion station, filling station, mold station, punching station, sterility assurance and other stations. During the operation of the equipment, the plastic particles are firstly extruded The machine continuously extrudes, and then forms a tubular tube embryo, which is cut off by a hot cutter when the length is appropriate, and transferred from the mold station to the filling station, where the bottle is blown to form a bottle body, and then the non-woven tube is produced. Bacterial products, but the products produced by this process still need to take the medicine with a syringe during the medication process, and then add the liquid medicine to the medicine that needs to be inj...
