A heating roller 105 having a circumferentially projecting projection 106 and a receiving wheel 111 is connected to a hollow drive shaft 112.
And the both ends of the drive shaft 112 are supported by support frames 114 and 11.
5 and is rotatably supported by bearings 116 and 117. A gear 118 for transmitting a rotational force is fixed to one end of the drive shaft 112, and a terminal unit 119 having a slip ring is fixed to the other end of the drive shaft 112 so as to provide electric resistance. In this configuration, a rod-shaped heating element 120 made of a body is inserted into the hollow portion 113.

14 and the drive shaft 112 is removed from the bearing 117 and the heating roll 105 to remove the heating roll 105 from between the support frames 114 and 115, or the heating roll 105, the two bearings 116 and 117, and the drive shaft 1
12 is removed from the support frames 114 and 115 as it is, and one of the bearings 116 and 117 is removed.
The heating roll 105 is removed by a procedure of extracting the heating roll 05 from the drive shaft 112, and is assembled by a procedure opposite to the above.

The heating roller 105 is removed by removing the heating roller 105 from the support frames 114 and 115 by moving the entire driving shaft 112 in the direction of the central axis, which is extremely troublesome. In addition, since at least one of the bearings 116 and 117 supporting the drive shaft 112 is moved, it is troublesome to perform alignment during assembly, and particularly to position the press die 106 for forming the vertical heat bonding portion so as to face accurately. .

である。This is because the heating roller 105 is fitted on the drive shaft 112 having a single structure because the heating element 112 is inserted, and the bushes 122 and 123 hold the heating roll 105 from both sides so as not to move in the center axis direction. Therefore, the portion of the drive shaft 112 where the heating roll 105 is mounted is
This is because the bushes 122 and 123 have a larger diameter than the portions supported by the bushings 16 and 117 so that the bushes 122 and 123 abut against the steps.

う点である。The problem to be solved by the present invention is that the conventional heating roll device in which a heating roll is mounted on a drive shaft having a single structure and both ends are supported by bearings on a support frame. The problem is that the removal and assembly of the heating roll is cumbersome, and the alignment during assembly is particularly troublesome.

You. In addition, the movable shaft, the heating roll, and the intermediate shaft are assembled by assembling the movable shaft in the central axis direction based on the stationary shaft in the central axis direction among the distal shaft and the proximal shaft. As a result, the trouble of removing and assembling the heating roll and the trouble of alignment during assembling are eliminated.
