  1. Operating principles and procedures of the prefilled syringe filling machine

The prefilled syringe filling machine is a device used for automatic filling of pre-filled syringes. Its operating principles are based on a series of steps, including changing pre-filled sealing components, disassembling filling needles and needle holders, operating plunger transfer devices, and disassembling vacuum chambers. The specific steps are as follows:

(1) Changing pre-filled sealing components: Replace the corresponding components such as filling needles, needle holders, and plunger transfer devices according to different product specifications.

To adapt to the filling of products with different specifications, the prefilled syringe filling machine needs to replace the corresponding components. Here are the methods for changing common components:

– Filling needles: Loosen the fixing nut of the filling needle and remove it from the needle head sleeve.

– Needle holders: Pull out the needle head sleeve from the needle holder and slowly remove the needle holder.

– Plunger transfer device: Loosen the fixing screw of the plunger rod and remove the plunger rod.

– Vacuum chamber: Disconnect the vacuum tube connection, loosen the fixing screw, and prevent it from falling.

– Suction cup and center plate: Loosen the fixing screw on the suction cup and center plate, and remove the suction cup and center positioning plate.

 

(2) Syringe filling: Fill the liquid into the pre-filled syringe through the XY platform and pump system, and perform vacuum suction and plunger sealing operations.

(3) Plunger transfer and sealing: Transfer the plunger to the correct position and perform sealing operation to ensure the syringe is sealed.

(4) Disassembling the vacuum chamber and shaking pot: Disassemble the vacuum chamber and shaking pot for cleaning and maintenance convenience.

(5) Disassembling the suction cup and center plate: Disassemble the suction cup and center plate for replacement and cleaning purposes.

 

  1. Common troubleshooting and repair

During the operation of the prefilled syringe filling machine, various malfunctions may occur. The following are the methods for troubleshooting common faults and considerations for repair:

Fault types: Faults are usually categorized into immediate machine stop, machine stop at origin, and automatic restart after machine stop. Locate the cause of the fault based on the alarm information and resolve the issue.

Common causes of faults: Fault causes may include lack of materials, power failures, wear of photoelectric switch reflectors, loose positions of proximity switches, loose synchronization belts, etc. Analyze the faults based on alarm information and equipment status, and take corresponding troubleshooting methods.

Equipment maintenance: Perform regular maintenance tasks on the equipment, including cleaning, lubrication, inspection of vulnerable parts, and functional testing. Establish a maintenance plan and follow it to ensure the stable operation of the equipment.

 

  1. Daily maintenance and regular maintenance plan for the prefilled syringe filling machine

Daily maintenance is crucial to ensure the normal operation of the prefilled syringe filling machine. The following are the contents and plans for daily maintenance and regular maintenance:

Daily cleaning: Regularly clean the equipment to avoid accumulation of residue and contamination. Pay attention to the selection of cleaning materials and avoid using organic solvents and corrosive substances.

Lubrication and inspection: Regularly lubricate and inspect the transmission components to ensure their normal operation and tightness.

Inspection of vulnerable parts: Regularly inspect the degree of wear on vulnerable parts and replace them in a timely manner to ensure the normal operation of the equipment.

Functional testing: Regularly perform functional testing of the equipment to ensure that all functions are working properly.

Maintenance records and analysis: Maintenance personnel should keep records of troubleshooting, maintenance tasks, and analysis to provide a basis for subsequent preventive measures.

By properly installing and maintaining the prefilled syringe filling machine, it can work stably and provide high-quality injector products. The above content provides a guide for the installation and maintenance of the prefilled syringe filling machine, assisting operators and maintenance personnel in performing correct operations and maintenance work, thereby improving the equipment’s lifespan and production efficiency.
