Drying system of a coated continuous film

摘要

A drying system of a coated continuous film equipped with roller conveyor devices of the continuous film that allow easy and rapid removal of the rollers from the system to facilitate cleaning and maintenance operations. The conveyor roller is substantially separable into two parts with at least one of the two support shafts separable from the rest of the roller to facilitate the disassembly and reassembly operations of the conveyor roller from and on the system. In this way, it is unnecessary to remove all the motion transmission elements connected to one of the two support shafts.

主权项

1. A drying system of a coated continuous film comprising a plurality of conveyor rollers (3) supported at ends by a first support (5) and a second support (6) mounted on side members (4a, 4b) of the drying system, wherein said conveyor roller (3) comprises:
a guide cylinder (7) of the coated continuous film; a first support shaft (9) integral with a first end (11) of said guide cylinder (7) housed in the first support (5); a second support shaft (10) placed at a second end (12) of said guide cylinder (7) housed in the second support (6) and having a first end (14) adapted to couple with said second end (12) of the guide cylinder (7), and wherein the first support (5) comprises:
a support flange (28) integral with the side member (4a) of the drying system by means of fixing bolts (43);a flange (29) connected to said support flange (28), there being provided a sliding device adapted to allow said flange (29) to slide toward and away from said support flange (28) along a direction parallel to the axis of the conveyor roller (3);an elastic device which exerts an axial force on the flange (29) in a direction moving said flange (29) toward the support flange (28), the axial movement of said first support shaft being prevented with respect to said flange (29), so that the guide cylinder (7) is maintained in contact with said second support shaft (10),and wherein the support flange (28) is arranged on the side member (4a) of the drying system so that the guide cylinder (7) together with the first support shaft (9) and the first support (5) can be removed from the drying system by sliding the guide cylinder (7) through the side member (4a).
