First, the overall structure of the blister packing machine

Pharmaceutical blister machine is one of the key equipment in modernized pharmaceutical production line, and its overall structure is divided into two parts: host part and control system.

(I) Main machine part

The host part mainly includes feeding system, molding system, cutting system and discharging system. These systems work together to complete the continuous production of blister.

1. Feeding system: It is responsible for automatically feeding the pharmaceutical raw materials into the blister packing machine blister molding area to ensure the accuracy and uniformity of the raw materials.

2. Forming System: Presses pharmaceutical raw materials into blisters of specified shapes and sizes through precise mold and pressure control,and then blister sealing in blister packing machine

3. Cutting system: In the process of continuous production of blisters, the blisters are cut off at the right time to form independent pharmaceutical packaging units.

4. Discharge system: conveying the cut off blisters to the collection area for subsequent packaging and transportation.

(ii) Control system

Control system is the "brain" of the blister packing machine, responsible for monitoring and regulating the host of the various aspects of work. It is usually composed of PLC (programmable logic controller) and touch screen to realize automation control, data recording and fault alarm functions.

Second, the blister packing machine workstation details

The workflow of the blister machine can be subdivided into the feeding station, blister packing machine blister molding station, cut off the workstation and the next workstation.

(A) feeding station

Feeding station is the starting point of blister production. In this station, pharmaceutical raw materials are accurately measured and fed into the molding system. Equipment such as vibrators or screw conveyors are used to ensure even distribution and smooth flow of raw materials.

(ii) Blister molding station of blister packing machine

The molding station is the core part of the blister machine. Here, pharmaceutical raw materials are pressed into the shape of blister by the mold under the action of high temperature and pressure. During the molding process, parameters such as temperature, pressure and time need to be strictly controlled to ensure the quality and stability of the blister.

(C) Cutting off station

The cutting station is responsible for cutting the continuously produced blisters according to the set length. The integrity and consistency of each blister is ensured by precise pneumatic or mechanical cutting devices.

(D) Unloading station

The unloading station is the end point of the blister packaging process. The cut blister packing machine are transported to the discharging system, and after collecting, organizing and counting, they are ready to enter the next packaging process.

Third, blister machine maintenance and maintenance

In order to ensure the stable operation and prolong the service life of the blister machine, regular maintenance and repair is essential.

(A) regular cleaning

Regular cleaning of the blister machine to remove dust and dirt accumulated on the surface. In particular, key parts such as molding dies and cutting devices need to be disassembled and cleaned regularly to prevent residues from affecting product quality.

(B) lubrication maintenance

Regular lubrication of the moving parts of the blister machine to reduce friction and wear. According to the requirements of the equipment manual, use the appropriate lubricant and lubrication cycle to ensure that the lubrication effect is durable.

(C) Regular inspection

Regularly conduct a comprehensive inspection of the blister packing machine, including the electrical system, air pressure system, transmission system, etc.. Promptly repair or replace damaged parts when problems are found to ensure the normal operation of the equipment.

In summary, blister packaging in pharmaceutical industry is one of the indispensable equipment in the pharmaceutical production line. Through its overall structure, station details and maintenance and maintenance of a comprehensive introduction, I hope to provide useful reference and guidance for the relevant operation and maintenance personnel.
