Each inside of extending roller 1, preheat roll 2, chill roll 3 all has the cavity that can charge into heat-conducting liquid.
The cutaway view of extension roller 1 as shown in Figure 2, extend roller 1 inside and have the roller of extension cavity 9, and extending roller 1 is the jacket type roller, the extension roller cavity 9 of its inside is connected with thermostatic oil bath 10, extending roller cavity 9 inner just can being full of at any time like this has thermostatical oil, and the surface temperature of extending roller 1 also can keep constant; Extend roller 1 for the six roots of sensation, because every rotating speed that extends roller 1 is all inequality, so each root extends the surface temperature of roller 1 also should be inequality, but from cost consideration, usually this six roots of sensation is extended roller 1 and be divided into two groups, it is one group that roller 1 is extended in three of front sides, and it is another group that three of rear sides extend roller 1, and the extension roller cavitys 9 that the inside of roller 1 is extended in three of front sides are connected with a thermostatic oil bath, the inside extension roller cavity 9 that three of rear sides is extended roller 1 is connected with another thermostatic oil bath.
The internal structure of three preheat rolls 2 is identical with the internal structure of extending roller 1, and three preheat roll internal cavities are connected with another thermostatic oil bath.
The internal structure of three cooling sticks 3 is also identical with the internal structure of extending roller 1, because the effect of cooling stick 3 is the polythene radiation-crosslinking thermal-contraction belts that are used for cooling off extend through, so in order to save cost, usually the two ends of the internal cavities of three cooling sticks 3 are fed in the normal temperature water tank and get final product.
In order to make whole extension process carry out continuously, the rear side at the extension apparatus of polythene radiation-crosslinking thermal-contraction belt is provided with unwinding rack 11, is used for polythene radiation-crosslinking thermal-contraction belt is constantly imported to preheating rod 2 usually; Front side at the extension apparatus of polythene radiation-crosslinking thermal-contraction belt also is provided with rolling frame 12, is used for the polythene radiation-crosslinking thermal-contraction belt that extends, cooled off is rolled.
In order to prevent that polythene radiation-crosslinking thermal-contraction belt is being offset to the process of preheating rod 2 from unwinding rack 11 to winding, also between unwinding rack 11 and preheating rod 2, be provided with a deviation correcting device 13; For the polythene radiation-crosslinking thermal-contraction belt rolling more timely that will extend, cool off to rolling frame 12, after rolling frame 12, also draw-gear 14 should be set.Deviation correcting device 13 and draw-gear 14 are usual means in the art, so be not described in detail in this.
Following mask body is introduced the extension method that extends polythene radiation-crosslinking thermal-contraction belt with the extension apparatus of this polythene radiation-crosslinking thermal-contraction belt, and it comprises the following step of carrying out successively;
A, preheating; The polythene radiation-crosslinking thermal-contraction belt that is placed on the unwinding rack 11 is at first passed deviation correcting device 13, walk around three preheat rolls 2 more successively, and it is adjacent on the part external peripheral surface of described three preheat rolls 2, the rotating speed of three preheat rolls 2 of maintenance is identical, surface temperature is identical, to prolong on the external peripheral surface of that preheat roll 2 that the tight rubber roll 7 of preheating is pressed on front side polythene radiation-crosslinking thermal-contraction belt is close on the external peripheral surface of preheat roll 2, to prevent the polythene radiation-crosslinking thermal-contraction belt skew.;
B, extension; The polythene radiation-crosslinking thermal-contraction belt of preheating being walked around successively the six roots of sensation extends roller 1, one and extends transition roller 8 again, and it is adjacent in the six roots of sensation extends roller 1 and extend on the part external peripheral surface of transition roller 8, regulate the rotating speed that extends roller 1, make every adjacent two rotating speeds that extend the rotating speed of the extension roller 1 that is positioned at the front side in the rollers 1 greater than the extension roller 1 that is positioned at rear side, the rotating speed that extends transition roller 8 extends the rotating speed of roller 1 greater than that root of front side; The six roots of sensation is extended three internal cavities that extend roller 1 that are positioned at the front side in the roller 1 and is communicated with a thermostatic oil bath, three that are positioned at rear side are extended communicating with another thermostatic oil bath of roller 1, and the temperature of extending that identical thermostatic oil bath of roller 1 with the front side is greater than extending the temperature of that identical thermostatic oil bath of roller 1 with rear side, thereby makes three temperature of extending rollers 1 that are positioned at the front side greater than three surface temperatures of extending rollers 1 that are positioned at rear side; Again extension is compressed polythene radiation-crosslinking thermal-contraction belt is close on the external peripheral surface that extends transition roller 8, to prevent the polythene radiation-crosslinking thermal-contraction belt skew.
C, cooling; The polythene radiation-crosslinking thermal-contraction belt of extend through is walked around three chill rolls 3 successively, and it is adjacent on the part external peripheral surface of described three chill rolls 3, keep the rotating speed of described three chill rolls 3 identical; Again cooling is compressed rubber roll 4 and be pressed on the external peripheral surface that is positioned at that middle chill roll 3, to prevent the polythene radiation-crosslinking thermal-contraction belt skew.
D, polythene radiation-crosslinking thermal-contraction belt is carried out air cooling with its winding again after described chill roll 3 is backed off a plurality of air cooling rollers 6, at last by draw-gear 14 with its traction winding again on the rolling frame 12.
Polythene radiation-crosslinking thermal-contraction belt is through preheat roll 2 whole heating, again when extending roller 1 to guarantee the polythene radiation-crosslinking thermal-contraction belt temperature since speed difference realize extending, adjust the speed difference that extends between roller 1 each roller and can obtain different ratios of elongation, heat and extend roller 1 surface, coating face is little than the die lateral shrinkage, extends evenly.
