[0061] Next, refer to Figure 1 to Figure 6 A first embodiment of the present invention will be described.

[0062] (spinning traction machine)

[0063] First, use figure 1 The configuration of the spinning take-up machine 1 including the induction heating roll 20 according to the first embodiment will be described. figure 1 It is a front view of the spinning take-off machine 1 . Additionally, the figure 1 The shown vertical direction, front-rear direction, and left-right direction are respectively defined as the vertical direction, front-rear direction, and left-right direction of the spinning take-up machine 1, and will be described below. The spinning take-up machine 1 has a structure in which a plurality of yarns Y spun from the spinning device 2 are drawn by the spinning drawing device 3 and then wound by the yarn winding device 4 .

[0064] The spinning device 2 produces a plurality of yarns Y by continuously spinning a molten polymer such as nylon or polyester. Th...

Abstract

Suppresses the heat generation of the fixing ring installed on the induction heating roller. The induction heating roller (20) includes: a roller unit (30); and a heater (50) having a coil (52) disposed inside the roller unit (30) in the radial direction. The roller unit (30) has: a roller main body (31) having an outer cylindrical portion (34) which is inductively heated by passing a magnetic flux generated by a current flowing through the coil (52) in the axial direction of the roller unit (30) a heat equalizing part (32) having a heat equalizing part (41) that is in contact with the inner peripheral surface (34b) of the outer cylinder part (34), extends in the axial direction, and has a heat conductivity higher than at least the inner peripheral surface (34b); A fixing ring for fixing the roller main body (31) and the heat soaking portion (32), provided so as to be in contact with the axial base end portion of the outer cylinder portion (34) and the axial base end portion of the heat soaking portion (32) (33); and arranged between the outer cylinder portion (34) and the coil (52) in the radial direction, and arranged on the base end side compared to the center of the outer cylinder portion (34) and closer to the front end than the fixed ring (33) side position of the first magnetic component (46).

Description

technical field [0001] The present invention relates to an induction heating roll and a spinning and drawing device equipped with the induction heating roll. Background technique [0002] Patent Document 1 discloses an induction heating roller for heating a yarn. The induction heating roller includes a hollow roller body and a coil arranged radially inside the roller body. When an alternating current flows through the coil, an eddy current is generated in the roller body due to electromagnetic induction, and the roller body generates heat due to Joule heat (that is, induction heating occurs). In addition, the induction heating roller has a structure supported on one side so that the wire can be easily wound. [0003] In general, in an induction heating roller, since it is difficult to uniformly generate heat in the axial direction, or heat radiation from the roller body to the outside tends to occur at axial end portions, the distribution of the surface temperature of the ...
