Blister packing machine heating plate station problem

(1) the forming of the PVC into bent, appear this kind of situation is often in the sealing station bubble, this problem occurs because the heating plate and the forming die is not parallel, uneven heating, causing big deformation of the heated to form a bent, appear this kind of circumstance needs to forming dies as a benchmark to leveling up and down heating plate;

(2) The forming PVC bubble holes in the inner and outer sides of the mold are always not full. This phenomenon may be caused by gaps in the heating plate and instability in the temperature of the heating plate! Therefore, there is no gap in the heating period during the operation of the heating plate.

(3) The air bubbles in the middle of the mold are not full, because the PVC is flexible after heating, and the PVC that is not held up in the operation process is naturally sagging under the influence of gravity. The middle PVC may be stuck on the cooling mold, leading to the rapid cooling and hardening of the PVC after heating, resulting in poor molding. Therefore, the heating plate should be 2 ~ 3mm higher than the blown mold, and the forming stepping plate should also be 3 ~ 4mm higher than the blown mold. Otherwise, in the process of forming, it may lead to the incomplete forming of the bubble in the middle of the mold.

(4) if the PVC forming bubbles are irregular, the temperature of 3 ~ 5 degrees needs to be increased. At the same time, because the ambient temperature has changed, the summer forming temperature can be 5 degrees lower, and the winter forming temperature is 5 degrees higher; If the forming is irregular and bad, consider whether the heating plate is damaged, whether the surface Teflon map layer falls off, and whether the temperature of the heating plate is normal. Carefully check and then do the corresponding treatment.

(5) if the formed PVC bubble cover is always swinging from side to side, then the reason is that the temperature of the heating plate is high, and reducing 3-5 degrees can solve the problem. Because the temperature is too high, PVC deformation exceeds a certain plastic critical point, forming irregular stretching, so there will be left and right swing.
