1. When the high-speed blister packaging machine is powered on, the green indicator light will illuminate. Turn on the two heating switches for forming and heat sealing respectively. The first temperature controller controls the forming temperature, typically preset to 100ºC. The second temperature controller controls the heat sealing temperature, preset to 130ºC-140ºC. The preset temperatures for the forming and heat sealing temperature controllers should be adjusted according to the specific situation.
2. Lower the pressure block on the feeding roller. Once the forming heating plate reaches the desired temperature, turn on the main machine. The PVC plastic will form first, ensuring the bubble openings align with the heat sealing mold holes. Note that the heat sealing mold cylinder lowers, pressing the aluminum foil. The aluminum foil will then move towards the punch. Observe whether the plastic (referring to the PVC already formed on the machine plate) moves left or right. If there is a deviation, adjust the feeding roller seat to change the feeding direction.
3. If the aluminum foil of the high-speed blister packaging machine deviates left or right, adjust the handwheel of the rotating roller seat to correct it. If it deviates forward or backward, adjust the movement of the packaging box.
4. After the heat sealing and loading process is normal, moderately open the feeder switch and gate to allow an appropriate amount of medicine (tablets, capsules, coatings) to enter the feeding chamber. If there is a small amount of material in the chamber, it can be manually replenished. If medicine is carried into the heat sealing mold, it will seriously affect synchronization. Therefore, if it sticks to the mold during aluminum foil sealing, the machine must be stopped for handling.
5. Due to the increased weight of the medicine in high-speed blister packaging machines, the aluminum foil tension and machine temperature may gradually change unevenly, potentially causing asynchronous forming and heat sealing, either ahead or behind. First, check if there are any gaps between the PVC plastic and the aluminum foil. Then, adjust using the machine's fine-tuning mechanism. The fine-tuning mechanism adjusts the mold forward and backward, depending on the adjustment interval or the front and back of the box. Therefore, it should be placed in the middle position before starting the machine before moving it forward or backward. Alternatively, the front box can be moved for adjustment. After correct adjustment, the blister pack will only be correctly aligned after completing a dozen or so cycles. Therefore, do not adjust it arbitrarily before the cycle is complete.
6. The heat-sealing quality (even, firm, and flat adhesion) of plastic and aluminum foil in high-speed blister packaging machines is judged by temperature or pressure and the flatness of the textured plate. If poor heat sealing occurs, generally, the temperature and pressure should be slightly lower, the regulator should be set to the correct temperature, and finally, the screw pressure should be adjusted.
7. For die-cutting misalignment, the die should be offset. Stop the machine and move the manual adjustment box; the die can then be adjusted to reposition.
8. In daily operation of high-speed blister packaging machines, it is essential to understand the machine's structural principle. The cam drives the rollers of the ejector pin seat, and the upper cover template is fixed in position. If poor blister sealing occurs, pay attention to the lower forming mold or heat sealing reaching the upper stop point, and tighten the column nuts. Failure to do so can easily lead to malfunctions, such as the ejector pin pressing the rollers and needle rollers seizing.
