Abstract
The utility relates to a heating calendaring roll for calendaring mill, which is characterized by comprising a roller body, a bidirectional rotary joint, an inner tube, a sealing ring and an end cover, wherein an inner hole is arranged in the center of the roller body, one end of the inner tube is connected with the sealing ring and inserted into the inner hole, the sealing ring divides the inner hole into two chambers, while the other end of the inner tube is connected with the bidirectional rotary joint; a plurality of heating holes are uniformly distributed on the roller bodies around the inner hole and both ends of the heating holes in the roller body are respectively provided with end covers; both ends of the heating holes are connected with a corresponding chamber in the inner holes through an inclined hole. The utility model has the advantages of high heat efficiency and small temperature differences of the calendaring roll at the left, middle and right sides.
Description
Technical field
The utility model relates to a kind of heating calender, relates in particular to a kind of heating calender of calender.
Background technology
The heating calender of existing calender generally adopts electrical heating or Steam Heating, and external also have an employing center macropore heat-conducting oil heating mode.Adopt electrical heating, the calender left, center, right temperature difference is big, and its temperature difference reaches more than 8 ℃, and along with the difference of roll surface requirement calendering temperature, the left, center, right temperature difference also can strengthen; The Steam Heating left, center, right temperature difference is slightly better than electrical heating, and its temperature difference is more than 5 ℃, but heating-up temperature can only 150 ℃ left and right, temperature requirement is high again, all higher requirement will be arranged to steam pressure, system sealing; And adopt center macropore heat-conducting oil heating mode abroad, though calender left, center, right thermal gradient energy be controlled at 3 ℃ left and right because reasons in structure, conduction oil conducts heat from endoporus to the roll surface distance, the thermal efficiency is not high, and is all influential to calendering temperature and speed.
Summary of the invention
At above-mentioned shortcoming, the utility model purpose is to provide the heating calender of the calender that a kind of thermal efficiency height and calender left, center, right have a narrow range of temperature.
Technology contents of the present utility model is, a kind of heating calender of calender, it is characterized in that it comprises roll body, two-way swivel joint, interior pipe, sealing ring and end cap, an endoporus is established out at center in roll body, interior Guan Yiduan connects a sealing ring and is inserted in the endoporus, sealing ring is divided into endoporus two chambers entirely, and the interior pipe other end is installed and connected two-way swivel joint; On the roll body of endoporus periphery, be evenly distributed with some bottoming holes, on the roll body at bottoming hole two ends, respectively be provided with an end cap; The two ends of each bottoming hole respectively by an inclined hole respectively with endoporus in corresponding chamber be communicated with.
The advantage that the utility model is compared with prior art had is: solve heating mirror roller left, center, right excessive temperature differentials, influence the difficult problem of calendering quality, can control the mirror roller left, center, right temperature difference in 2 ℃, realize high-quality calendering; And the thermal efficiency improves, and the calender temperature improves, and calendering speeds up, and calendering efficient improves.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiment
As shown in Figure 1, a kind of heating calender of calender, it is characterized in that it comprises roll body 1, two-way swivel joint 2, interior pipe 3, sealing ring 4 and end cap 5, an endoporus 1.1 is established out at center in roll body 1, interior pipe 3 one ends connect a sealing ring 4 and are inserted in the endoporus 1.1, sealing ring 4 is divided into endoporus 1.1 two chambers entirely, and interior pipe 3 other ends are installed and connected two-way swivel joint 2; On the roll body 1 of endoporus 1.1 peripheries, be evenly distributed with some bottoming holes 1.2, on the roll body at bottoming hole 1.2 two ends, respectively be provided with an end cap 5; The two ends of each bottoming hole 1.2 respectively by an inclined hole 1.3 respectively with endoporus 1.1 in corresponding chamber be communicated with.
