Embodiment
[0013] A kind of plastic cooling roller of the present embodiment comprises hollow roller 1; The two ends of roller 1 are respectively provided with water inlet and water outlet; Roller 1 inner wall is evenly laid with condensing pipe 2; The two ends of condensing pipe 2 are respectively connected with Water inlet and outlet connection. On the inner wall of the roller 1, semiconductor coolers 3 are evenly spaced; on the outer side of the semiconductor cooler 3, a heat pipe 4 is mounted, and the heat pipe 4 extends from one end of the roller 1, and a set of cooling fins (in the figure) not shown) fit.
[0014] The semiconductor refrigerator 3 in this embodiment is formed by stacking two stages of semiconductor refrigerators, and the temperature difference between the hot and cold ends is above 60 degrees Celsius. If you need a stronger effect, you can also use the three-level refrigeration sheet superimposed, and the temperature difference can reach more than 80 degrees Celsiu...

The invention relates to a plastic cooling roller, belonging to the technical field of polymer material preparation. The plastic cooling roller comprises a hollow roller, wherein a water inlet and a water outlet are formed at the two ends of the roller respectively; condenser pipes are uniformly laid on the inner wall of the roller at intervals; the two ends of the condenser pipes are respectively connected with the water inlet and the water outlet; semiconductor coolers are uniformly stuck to the inner wall of the roller at intervals; heat conducting pipes are stuck to the outside of the semiconductor coolers and extend out from one end of the roller; the extension endpoints of the heat conducting pipes are fit with a group of cooling fins. The plastic cooling roller provided by the invention has the beneficial effects that the semiconductor coolers are laid in the roller and can be immediately started for assisting when the circulating water is not cooled in time; the semiconductor coolers can be superposed in multiple layers, so that the cooling effects are good; generally, the multistage cooler structure can achieve two-stage temperature difference above 80 DEG C; the plastic cooling roller can be used for quick cooling and is enough to cope with any emergency.
Description
technical field [0001] The invention relates to a plastic cooling roller, which belongs to the technical field of polymer material manufacturing. Background technique [0002] In the existing EVA film production process, when the calendered film or adhesive tape is coated, in order to reduce the deformation caused by the shrinkage of the hot material when the finished product is rolled, the material is passed through a cooling roller to cool down the temperature before the roll is rolled to achieve reduction. deformation of the material. [0003] The current general method is to use circulating water for cooling, set cooling pipes in the rollers, and then feed cold water. When the continuous working time is too long, or the ambient temperature is high, the effect of this cooling method will be significantly reduced. Moreover, such a cooling method does not have any adjustment capability. Contents of the invention [0004] The technical problem to be solved by the invent...
