A PRESS ROLL OF LARGE SCALE MIXING MACHINE OR CALENDER FOR PLASTICS OR RUBBER
Document Type and Number:
WIPO Patent Application WO/2006/056139
Kind Code:
A1
Abstract:
A press roll of mixing machine or calendar, more particularly, of large scale mixing machine or calender for plastics or rubber comprises: a bearing group (1), a support arm (2), a frame (3), a cantilever beam (4), a revolving joint (5), a compression spring (6), a nut cap (7), a roller (8), an inner pipe (9), a stopper (10) and an end cap (11). There are many bores of varied sizes inside of the roller (8). By improving the material of roller (8), modifying the structure of the roller and varying the distribution of the bores to facilitate the hot fluid passing in and out, it ensures that the surface temperature of the roller distributes identically, the micro-thermal expansion of roller face is all the same, and the roller face is kept evenly. Therefor, it can manufacture a wide press roll with length of working face L1 being in the range of 3750mm-8000mm and diameter of working face being in the range of 850mm-1525mm.
