Description

A kind of pre- traction apparatuss of the melt for plastic cement extrusion shaping machine
Technical field
This utility model is related to a kind of pre- traction apparatuss of melt for plastic cement extrusion shaping machine.
Background technology
Traditional plastic cement extrusion shaping machine draws from the melt that T-shaped mould head is extruded through stack, if necessary to produce Compared with thin product (by taking below 0.5mm PP as an example), if calendering roll surface temperature is relatively low, due to melt, temperature is reduced when the roll surface, As a result molding is difficult in mould;If calendering roll surface temperature is higher, roll banding is easy for.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 being typically merely able to production thickness with calender system Spend the PP products in more than 0.5mm.
All it is at present directly to be driven by two ends chain below or mould directly drive if not adopting calender system, Because the forward speed of chain or mould has differences with the extruded velocity of melt, usually near T-shaped mould head end is thicker, remote T-shaped Die end is relatively thin, can cause the uneven of product thickness.

Description of the drawings
This utility model is further illustrated with reference to the accompanying drawings and examples:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 be this utility model be arranged on plastic cement extrusion shaping machine when schematic diagram.
Specific embodiment
With reference to Fig. 1~Fig. 2, this utility model is a kind of pre- traction apparatuss of melt for plastic cement extrusion shaping machine, including:
Frame 1;
Upper carry-over pinch rolls 2 and lower carry-over pinch rolls 3, are all installed in rotation in frame 1, between upper carry-over pinch rolls 2 and lower carry-over pinch rolls 3 Spacing it is adjustable;
Some first traction components, installed in upper carry-over pinch rolls 2, the first traction component protrudes from carry-over pinch rolls 2;
Some second traction components, on lower carry-over pinch rolls 3, the second traction component protrudes from lower carry-over pinch rolls 3, and second leads Draw component to be engaged with the first traction component.Using this utility model of said structure by upper carry-over pinch rolls 2 and lower carry-over pinch rolls 3 Upper setting protrudes from second traction component and the first traction component of carry-over pinch rolls 2 and lower carry-over pinch rolls 3, by the first traction component Coordinate with the second traction component and melt is drawn, the first traction component and the second traction component and melt in distraction procedure The area contact of molding is not required to, even if the region cooling, also not interfering with melt needs the region of molding, while and serving good Good traction effect.This utility model simple and ingenious structure, effect is significant.
As illustrated, the first traction component is set to a upper traction circle 4 annular in shape, upper traction circle 4 is set in traction On roller 2;Second traction component is set to a lower traction circle 5 annular in shape, and lower traction circle 5 is set on lower carry-over pinch rolls 3;Upper traction All be provided with some slide keys 6 on roller 2 and lower carry-over pinch rolls 3, slide key 6 be used for by upper traction enclose 4 be fixed on upper carry-over pinch rolls 2 and Lower traction is enclosed into 5 to be fixed on lower carry-over pinch rolls 3;A groove 7, slide key 6 are all provided with upper carry-over pinch rolls 2 and lower carry-over pinch rolls 3 It is connected with upper carry-over pinch rolls 2 or lower carry-over pinch rolls 3 in groove 7 and by screw.Can adjust according to actual needs traction circle or under Traction circle position, to adapt to the mould of different size, typically when in use, both sides can place it is multiple contact with each other on lead Draw circle or lower traction circle, to carry out pressing process to the edge of melt.
