M405306 cold air can cool down, and the extended items can also be reduced by the cold air blown out from the air holes to extend the life of the machine. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. As shown in FIG. 1 and FIG. 2, the preferred embodiment of the air-cooled pressure-expanding roller of the present invention includes a shaft and a shaft, and an inner drum 20 and an outer drum 30 fixed on the shaft 10. The outer wheel barrel 3〇 is wrapped around the outer wheel barrel 2〇 and defines a space 4〇 together with the shaft 10 and the inner wheel barrel 2〇. The shaft 10 extends along an axis L and has a first end portion η, a second end portion 12 opposite to the first end portion 11 , and a first end portion U extending to the second end portion a circumferential surface 13 of the 12 and a drainage hole 14 extending along the axis l and disposed at the first end portion, the drainage hole 14 has a lead-in end 141 disposed at an end surface of the first end portion 11 and a lead-in The end 141 is opposite and disposed at the leading end 142 of the peripheral surface 13. . The inner wheel barrel 2 has a hollow barrel shape, and has an inner barrel wall 21 surrounding the axis l, and an inner end plate 22 fixed between the inner barrel wall 2 and the shaft 1 , and is fixed thereto. The support plate 23' between the inner tub wall 21 and the shaft 1' is mostly protruded from the convex ring 24 of the inner tub wall 21, and most of the annular grooves 25 and two are disposed on the side of the convex core 24 in the axial direction. The inner tub wall 21 and the inner chamber 27 between the inner end plates 22 and the support plate 23. The inner tub wall 2i has an outer annulus 211 adjacent to the space 40, and the inner end panels 22 each have an adjacent one. The first end surface 221 of the 4 〇 of the mortuary room and a perforation 222 of the inner chamber 27 and the space 404 are located between the inner end plates 22 and have a communication chamber 27 through hole 231. Referring to FIG. 3 and FIG. 4, the convex rings 24 are protruded from the outer ring surface 211 and are axially spaced apart. The convex rings 24 are respectively provided with a plurality of corresponding axes L and the ring grooves 25 are connected. Through slots 241, the slots 241 and the annular grooves 25 define a plurality of air passages 26' that communicate in the axial and circumferential directions. The convex rings 24 and the support plate 23 are disposed along the axis L, and the convex rings 24 are respectively disposed between the support plate 23 and the inner end plates 22. The lead end 142 of the drain hole 14 is disposed inside one of the inner end plates 22, and is permeable to the through holes 222, such as 27 or s, and the through holes 23 1 are connected to the space 40. The outer drum 30 has an outer tub wall 31 surrounding the outer tub wall 21 and two outer end plates fixed between the outer tub wall 31 and the shaft 1 。. The outer wall 3 1 has an inner side surface 31 11 adjacent to the space 40, an outer side surface 312 opposite to the inner side surface 311, and a plurality of air holes 313 extending through the inner side surface 3 ι and the outer side surface 312. The side surface 312 has an intermediate portion 314 and two side end portions 315 respectively corresponding to the outer end plates 32. The outer side surface 312 is gradually inclined toward the axis L by the side portion 315 of the inter-flank portion 314. The air vent 313 can be connected to the outside of the roller by the space 4〇. The outer outer end plates 32 each have a second end surface 321 adjacent to the space 4, and the circumference of the convex ring 24 is urged against the inner side surface 311 of the outer tub wall 31, and the air guiding passages 26 are disposed at The outer annular surface 21 is between the inner surface 3丨丨 and the inner side surface 3丨丨. "As shown in FIG. 2 and FIG. 4, 'When the roller is used for the object to be pressed, [I work, cold air will be input from the introduction end 141 of the drainage hole 14 and 1405306' and the bow end 142 is bowed. φ Ganshan., _L to the inner chamber 27 between the inner end plate 22 and the support plate 23, and then through the through hole 231 to the other inner chamber η, and in the inner end plate 22 After the perforation 222 is drained into the space buckle, after the cold air is taken, the cold air will flow along the axial direction of the roller, and the air passage of the air passage is defined by the groove... The action of the four passages 26 in the axial direction and the circumferential direction allows the cold air to cool down the outer drum 3G, and the cold air is finally discharged from the air holes 313 toward the outside of the roller as indicated by the arrow. Even if the article to be stretched has a relatively high heat, and the outer tub wall 31 of the outer drum 30 is in contact with the (four) article, the temperature rises due to the heat guide, and the cold air that continuously flows in the space 4 is utilized. The cooling effect can make the outer drum of the 2 produce the effect of cooling, and the (4) iq and the inner drum can not be raised. Moreover, the air holes 3i3 t on the surface of the roller continuously discharge cold air to cause the object to be pressed to pass through the roller (four) while being directly blown by the cold air, thereby achieving the purpose of cooling. In addition, when cold air is discharged from the air holes 313 #, cold air will glimpse between the outer side surface of the wheel drum 3 and the object to be pressed, and therefore, the outer tub wall 31 of the cold outer drum 30 is performed. Cooling, so the object to be stretched... is not transmitted to the sleeve 1〇 and the bearings (not shown) that are sleeved at both ends of the rod 1 through the outer drum 3〇, which can extend the service life of the machine. . = 'The cold air is input from the introduction end (4) of the drainage hole 14 to the extension wheel, and is first drained from the outlet end 42 to the inner chamber 27, and then 231 to the other inner chamber 27, In this way, the effect of re-draining into the space 4 through the inner wheel hole 222 can provide the M405306 space 40 with a regulated air flow, which can reduce the air pressure pulse and make the cold air discharged from the air holes 3 13 Stable to ensure the quality of the pressure. 3;' Therefore, the shaft of the roller of the present invention does not heat up, and is not subject to a small thermal expansion rate. Even if it is long (four), it is not easily deformed, and the dynamic balance is not lost, and the mechanical structure is not bent and deformed. Moreover, the shaft 1〇 does not increase the output of the motor (not shown) due to thermal expansion, and the life of the motor is prolonged, and the bearing of the shaft=10 is stable even if it is operated for a long time. The above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the new description content. , are still within the scope of this new patent.
