Subpackaging machine

Abstract

The invention relates to the technical field of medical industry clean room powder-injection subpackaging, in particular to a subpackaging machine. The subpackaging machine comprises a machine table face. A bottle feeding and discharging mechanism, a screw subpackaging mechanism, a powder adding mechanism, a penicillin bottle transmission mechanism, a plug pressing mechanism and a controller are arranged at the upper end of the machine table face. A closed air return device is further included and comprises an air return air pipe arranged at the lower end of the machine table face. The air return air pipe is externally connected with an air conditioner through an air conditioner connecting pipe. Multiple through holes are formed in a face plate of the machine table face and communicate with the air return air pipe through connecting parts. Through additional mounting of the closed air return device at the bottom of the machine table face of the subpackaging machine, airflow in the whole subpackaging machine isolation space is from top to bottom and from inside to outside, a turbulent flow layer in the whole subpackaging machine area is eliminated, dust and other particles generatedin the subpackaging process are eliminated in time, smoke module testing is smooth, and the GMP requirement is met.

Description

technical field [0001] The invention relates to the technical field of powder injection dispensing in a clean room of the pharmaceutical industry, in particular to a dispensing machine. Background technique [0002] The packaging process of injection products in the pharmaceutical industry has strict regulatory requirements. The existing machine space and structural design are unreasonable, and the installation of machine parts cannot be completely sealed. The isolation door needs to be opened to install machine parts, and there is a high risk of pollution. If the dust and particles generated during the packaging process cannot be eliminated in time, it will affect the packaging environment. [0003] In addition, the impact of air flow on sub-package production is self-evident, and the ordinary air intake and return air mode is difficult to meet the production requirements. And the air flow in the filling machine area is even more difficult to control, which makes it diffic...

[0002] The packaging process of injection products in the pharmaceutical industry has strict regulatory requirements. The existing machine space and structural design are unreasonable, and the installation of machine parts cannot be completely sealed. The isolation door needs to be opened to install machine parts, and there is a high risk of pollution. If the dust and particles generated during the packaging process cannot be eliminated in time, it will affect the packaging environment

[0003] In addition, the impact of air flow on sub-package production is self-evident, and the ordinary air intake and return air mode is difficult to meet the production requirements

And the air flow in the filling machine area is even more difficult to control, which makes it difficult for the airflow and pressure difference in the filling machine area to meet the GMP requirements, so that the environment of the product cannot be guaranteed.
