How to deal with the malfunction of blister plate cartoning machine?

Wrinkle and offset of aluminium foil

A. Possible phenomena: 1. Rust and dirt on the mesh; 2. Aluminum foil turning rod is not perpendicular to the vertical line of PVC plastic sheet; 3. Aluminum foil and PVC plastic are not uniformly bonded (not parallel); 4. The mesh plate is not well matched with the mold, and the aluminum foil adhesive layer is not uniform.

B. Corresponding solutions: 1. Cleaning with steel wire side or sharpening with saw blade; 2. Adjusting the support of turning roll of cushion and correcting die does not conform; 3. Tearing off aluminium foil, adjusting position and re-bonding; 4. Replacing aluminium foil with two-layer aluminium foil folding reticulation die or oil stone according to heat seal condition, partially polishing the lower die plane.

The heat seal is not good after cutting off.

A. Possible phenomena: 1. Insufficient pressure or preferred position of hot-seal upper cylinder; 2. Insufficient temperature or pressure or preferred position of hot-seal upper cylinder; 3. Incorrect distance between punching die and hot-seal die

B. Corresponding solutions: 1. Regulating and adjusting cylinder pressure (pressure regulating valve) while checking whether the silicon rubber plate is talented, replaceable and desirable, between the copper cushion cylinder and the heat seal (copper thickness book is decided as appropriate) (Note: when adjusting, stop the upper dead point); 2. Regulating the temperature of the thermostat, as far as possible, by adjusting the pressure to control, so that the temperature remains constant at about 140 oC (as appropriate); 3. Adjusting the temperature of the thermostat; Movable die, box and injection have been adjusted, and factors such as transportation vibration and long-term use of displacement deformation or template change have been taken into account.
