Detailed description of the invention
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
This specification (include any accessory claim, summary and accompanying drawing) disclosed in any feature, unless specifically stated otherwise, all can by other equivalences or there is the alternative features of similar purpose replaced. That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Below the structure of the cooling system to this utility model PVC film calendering formation and principle are described in detail.
Fig. 1 illustrates the perspective view of roller in the cooling system of the PVC film calendering formation according to this utility model exemplary embodiment, and Fig. 2 illustrates the sectional structure schematic diagram of roller in the cooling system of the PVC film calendering formation according to this utility model exemplary embodiment.
As depicted in figs. 1 and 2, according to exemplary embodiment of the present utility model, the described cooling system for PVC film calendering formation includes roller and chilled(cooling) water supply (CWS) unit (not shown). Wherein, roller is to carry out PVC film rolling the roller in the roller mainly calendering post-treatment step related in the critical piece processed and this utility model, in order to occur Memorability resilience to shrink and wrinkling after realizing the effect of very fast cooling and shaping and preventing film to be heated, it is necessary to when utilizing roller that PVC film is carried out corresponding post-treatment, it is circulated refrigeration. According to exemplary embodiment of the present utility model, roller can be dandy roll and/or silica gel roller.
Specifically, roller includes cylinder 1 and is positioned at the end-blocking assembly 2 at cylinder 1 two ends. Wherein, end-blocking assembly 2 can support axle or end seal bearing, the main supporting realizing the sealing to cylinder 1 and pair roller barrel for end.Roller can be the dead axle roller that rotates together with axle (not shown), it is also possible to be around the rotating shaft roller that axle rotates, and axle can pass through welding or the mode such as threaded is fixed on the one or both ends of roller.
Water inlet usually directly offered respectively by roller of the prior art on the spindle unit at roller two ends and outlet carries out cooling down, cooling water enters from one end of roller and flows out from the other end of roller, its cooling process is shorter, and owing to cylinder is thicker, causes that cooling effect is not good. The structure of this utility model also pair roller barrel has been improved, specifically, cylinder 1 two ends are respectively arranged with water inlet 3 and outlet 4, cylinder 1 includes outer cylinder body 5 and inner barrel 6, condensation channel 7 it is provided with between outer cylinder body 5 and inner barrel 6, the two ends of condensation channel 7 are connected with the water inlet 3 at cylinder 1 two ends and outlet 4 respectively, and chilled(cooling) water supply (CWS) unit is connected with water inlet 3 and outlet 4 to supply recirculated cooling water in cylinder 1 respectively. Owing to being provided with double-layer barrel, therefore, it is possible to make recirculated cooling water enter in cylinder 1 via the condensation channel 7 closer to PVC film, PVC film being cooled down, cooling effect is more preferably.
As in figure 2 it is shown, according to exemplary embodiment of the present utility model, can also arrange many condensing tubes 8 in condensation channel 7 equably, condensing tube 8 is axial arranged along cylinder 1, and the two ends of condensing tube 8 are connected with water inlet 3 and outlet 4 respectively. Now, recirculated cooling water from water inlet 3 enter cylinder 1 and enter condensation channel 7 many condensing tubes 8 in, roller rotate thus PVC film is cooled down, recirculated cooling water is discharged from outlet 4 more afterwards. Adopt the many condensing tubes 8 being evenly arranged to cool down, help to ensure that the uniformity of cooling effect and extend the cooling process of cooling water.
According to exemplary embodiment of the present utility model, chilled(cooling) water supply (CWS) unit 5 is the adjustable frozen water machine of temperature. Specifically, frozen water machine is set as, and the cooling water circulating offer 0��5 DEG C to roller cools down with the PVC film on pair roller barrel. Owing to temperature is adjustable, therefore frozen water machine can provide the cooling water of design temperature constantly to roller, it is to avoid the harmful effect of extraneous factor; Further, the cooling water of its 0��5 DEG C provided ensure that PVC film has good very fast cooling and shaping effect, it is prevented that it occurs Memorability resilience to shrink and wrinkling after being heated.
This utility model is by improving the refrigeration of recirculated water, relatively big and that temperature is higher for extraneous factor impact cooling tower is changed to and can set that the frozen water machine of temperature cools down, the PVC film cooling and shaping obtained is respond well and disclosure satisfy that the requirement of goods, occurs without any modification and abnormal phenomena. After adopting above-mentioned cooling system, the requirement of experiment of sunshading board goods can be fully met, be suitable to the use of sunshading board membrane product.
Therefore, the cooling system of PVC film calendering formation of the present utility model improves the structure of roller on the one hand so that water intake mode science more and cooling effect are more preferably; On the other hand by improving the refrigeration of recirculated water, relatively big and that temperature is higher for extraneous factor impact cooling tower is changed to the offer that can set that the frozen water machine of temperature is circulated cooling water.
This utility model is not limited to aforesaid detailed description of the invention. This utility model expands to any new feature disclosed in this manual or any new combination, and the step of the arbitrary new method disclosed or process or any new combination.
