Three-layer co-extrusion film blower adopts advanced technologies such as new high efficiency and low energy consumption extrusion unit, IBC bubble internal cooling system, +360 degree horizontal upward traction and rotation system, photoelectric automatic deviation correction device, automatic winding and film tension control, computer screen automatic control system, etc. It has the advantages of higher output, good plasticization, low energy consumption and simple operation. It completely solves the problems of lotus leaf edge and winding head, and makes the product quality to a new level.
After the completion of the rapid observation of bubble deformation, if there is deformation should be adjusted in time, first check whether the gap between the die is adjustable, whether the foam stabilizing board is close to the bubble, if there is no problem to check whether there are open doors and windows, after detection, timely treatment. Observe whether the membrane is inclined or not. If it is tilted, use the baffle to block it. After the film is stabilized, the thickness and width of the film are measured to see if the required standard is met.
Thickness adjustment of die clearance, or appropriate reduction of air flow in the air ring to further expand the film, can also properly increase the traction speed to make its thickness thinner; if the thickness is thinner, the opposite is true. The width is controlled by an air pump, and the width of the interpolated film is measured to meet the standard. If not, the insert plate should be adjusted to meet the standard. Observe the symmetry of the inserted film, whether there is a dislocation phenomenon, if there is dislocation, we should make timely adjustments.
