Flat aluminum-plastic blister packaging machineThe whole machine adopts segmented combination: PVC forming, feeding, and heat sealing are in one section, and tropical aluminum cold forming, heat sealing, and punching are in one section for separate packaging. This machine is widely used for capsule, tablet, sugar coating, capsule, injection, irregular shape, as well as medical equipment, light food, electronic component blister sealing packaging.
The common problems and solutions of flat aluminum-plastic blister packaging machine are as follows:
1. Incomplete/damaged molding
Mainly caused by insufficient sealing of the mold or abnormal air pressure. It is necessary to adjust the parallelism of the upper and lower molds, check the condition of the sealing ring, replace damaged parts, and optimize the compressed air pressure (0.6-0.8MPa) and blowing time. If PVC shrinks unevenly after heating, the material should be replaced in a timely manner.
2. PVC film deviation or unilateral tightness
It is necessary to calibrate the installation position of the mold to ensure alignment with the centerline of the track, adjust the track width to match the film width, and increase the cooling water flow if necessary to prevent PVC from being deformed by heat.
3. Poor heat sealing/unclear mesh pattern
When the temperature is insufficient or the pressure is uneven, it is necessary to increase the heat sealing temperature (usually 120-150 ℃) and level the contact surface between the upper and lower films. Mesh blockage requires cleaning residue with a steel brush, while aluminum foil penetration requires reducing temperature or pressure.
4. Aluminum foil wrinkles/diagonal wrinkles
Adjust the left and right height knobs of the front pressure rod of the heat sealing module to eliminate unilateral tension, while checking the parallelism of the aluminum foil pressing wheel and aligning it with the track.
5. Leakage or accumulation of excess pieces
By adjusting the opening size of the feeder to match the material flow rate, optimizing the temperature of the upper and lower heating plates (usually 90-110 ℃ in the forming section) to improve the foaming effect, and adjusting the contact height between the brush and the material.
6. Offset of punching position
The lateral offset needs to be corrected for the installation angle of the forming/heat sealing mold, and the longitudinal offset can be calibrated by adjusting the punching and moving handle to adjust the stroke. Regularly check the tension of the synchronous belt to prevent slipping.
7. Abnormal operation of equipment
When the heat sealed component does not heat up, priority should be given to troubleshooting circuit breaks, damaged heating tubes, or blown fuses, and corresponding replacement of faulty components should be carried out. Temperature runaway requires detection of thermocouple circuit or replacement of temperature regulator. The transmission system card immediately needs to lubricate the guide rail and gear set, remove foreign objects from moving parts, and adjust the belt tension.
