Description
Technical field
The present invention relates to a kind of pre- traction apparatuss of the melt for plastic cement extrusion shaping machine.
Background technology
The melt that traditional plastic cement extrusion shaping machine is extruded from t pattern head draws through stack, if necessary to produce
Compared with thin product (), if calendering roll surface temperature is relatively low, due to melt, temperature reduces when the roll surface taking below 0.5mm pp as a example,
Result is difficult to molding in mould；If calendering roll surface temperature is higher, it is easy for roll banding.The only larger product of thickness,
The relatively low stack of roll surface temperature is just not enough to its temperature to drop too much, so with calender system be typically merely able to produce thick
Degree is in the pp product of more than 0.5mm.
If not adopting calender system, it is all directly to pass through two ends chain below to drive or mould directly drive at present,
The speed that moves ahead due to chain or mould is had differences with the extruded velocity of melt, and usually near t pattern head end is thicker, remote t type
Die end is relatively thin, can cause the uneven of product thickness.
