Description
Technical field
The present invention relates to a kind of pre- traction devices of the melt for plastic cement extrusion shaping machine.
Background technique
The melt that traditional plastic cement extrusion shaping machine is squeezed out from T-die is by stack traction, if necessary to produce
Compared with thin product (by taking 0.5mm or less PP as an example), if calendering roll surface temperature is lower, since temperature reduces when melt passes through roll surface,
As a result it is difficult to form in molding die；If it is higher to roll roll surface temperature, it is easy for roll banding.The only biggish product of thickness,
The lower stack of roll surface temperature is just not enough to its temperature to drop too much, so being generally merely able to production thickness with calender system
Spend the PP product in 0.5mm or more.
If not using calender system, is all directly driven at present by both ends chain below or mold directly drives,
Since the extruded velocity of the forward speed and melt of chain or mold has differences, usually close T-shaped mould head end is thicker, remote T-type
Die end is relatively thin, will cause the uneven of product thickness.
