DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0013] Specific implementation method: Combination Figure 1 As shown, a roller for a vulcanizer includes a cylinder 5, and the two ends of the cylinder 5 are respectively sealed and connected to an input shaft 1 and a support shaft 7 through an outer support ring 2. The support shaft 7 is provided with a channel running through its two ends. One end of an inner tube 8 penetrates into the cylinder 5 through the channel and is sealed and connected to the input shaft 1. The inner tube 8 is coaxial with the support shaft 7. The two ends of the channel in the support shaft 7 are sealed and connected to the inner tube 8 through a retaining ring. The end of the inner tube 8 located outside the support shaft 7 is closed and the outer circumference of the end is provided with a plurality of third through holes 81. An inner tube 4 located outside the inner tube 8 and sealed and connected to the inner tube 8 at both ends has a gap with the inner wall of the cylinder 5 so as to allow heat medium to pass through so as to keep the cylinder 5 at a required temperature. The inner tube 8 is provided with a plurality of fourth through holes 82 at the position between the input shaft 1 and the inner tube 4. The inner and outer ends of the support shaft 7 are respectively provided with a plurality of first through holes 71 and a plurality of second through holes 72. The first through holes 71 and the second through holes 72 are located between the two retaining rings. When in use, combined with Figure 1As shown, the heat medium enters the inner tube 8 from the third through hole 81, then enters the interior of the cylinder 5 from the fourth through hole 82, then enters the first through hole 71 through the gap between the inner cylinder 4 and the inner wall of the cylinder 5, then flows to the left through the gap between the inner channel of the support shaft 7 and the inner tube 8 and finally flows out from the second through hole 72.

[0014] When in use, the left end of the inner tube 8 and the left end of the support shaft 7 can be connected to the liquid outlet pipe and the liquid return pipe of the heat medium supply source respectively through a rotary connector (not belonging to the present device, the rotary connector is provided with rotary sealing rings on both sides of the third through hole 81 and the second through hole 72, the outer shell of the rotary connector is provided with a liquid inlet between the rotary sealing rings on both sides of the third through hole 81, the outer shell of the rotary connector is provided with a liquid outlet between the rotary sealing rings on both sides of the second through hole 72, and the rotary connector is rotationally sealed with the inner tube 8 and the support shaft 7).

[0015] The support shaft 7 is sealed and connected to the cylinder body 5 through a second inner support ring 6 at one end of the first through hole 71 close to the inner cylinder 4. The second inner support ring 6 is provided with connecting holes 61 running through both sides thereof, and the heat medium can pass through the connecting holes 61. The second inner support ring 6 improves the connection strength between the support shaft 7 and the cylinder body 5.

[0016] The end of the input shaft 1 close to the inner cylinder 4 is sealed and connected to the cylinder 5 through the first inner support ring 3 , and the second inner support ring 6 improves the connection strength between the support shaft 7 and the cylinder 5 .

[0017] An exhaust pipe 73 is also provided on the support shaft 7 at a position corresponding to the first through hole 71, and the outer end of the exhaust pipe 73 is close to the inner wall of the cylinder 5. Since the outer wall of the support shaft 7 is far away from the inner wall of the cylinder 5, the gas at the top of the cylinder 5 is difficult to be discharged directly from the first through hole 71. When the exhaust pipe 73 rotates to above the support shaft 7 and is close to a vertical state, the gas at the top of the cylinder 5 can enter the exhaust pipe 73 and finally be discharged from the second through hole 72, so there is less gas retained at the top of the cylinder 5.

[0018] The roller for the vulcanizer of the present application is more convenient for arranging pipelines because the inlet and outlet of the heat medium are both arranged on one side of the roller.

[0019] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
