The implementation principle of the heating roller with uniform surface heating in the embodiment of the application is as follows: when hot oil is injected from the oil inlet of the shell 31, the hot oil moves towards the direction close to the push block 322 by pushing the push shaft 321, so that the hot oil flows into the first oil inlet cavity 41 from the oil inlet of the shell 31; with the continuous injection of hot oil, the hot oil pushes the push block 322 to move towards the direction of the mandrel 34, and as only the cross-sectional area of the long side of the push block 322 is matched with the cross-sectional area of the short side of the oil inlet cavity II 42, when the long side of the push block 322 moves to the long side of the oil inlet cavity II 42 until the long side of the push block 322 blocks the oil flow channel 341 of the mandrel 34, a gap through which the hot oil can flow exists between the push block 322 and the oil inlet cavity II 42, so that the hot oil in the oil inlet cavity I41 flows into the oil inlet cavity II 42;
hot oil entering the oil inlet cavity II 42 pushes the gasket 351 to move towards the direction close to the sealing sleeve 352, so that the gasket 351 is separated from abutting against the bracket part I421, and the limiting head 354 is separated from abutting against the bracket part II 431 and the bracket groove 342; at this time, the spring 355 is compressed, and hot oil in the oil inlet cavity II 42 enters the oil inlet cavity III 43; hot oil in the oil inlet cavity II 42 can be stored in the oil inlet cavity III 43;
meanwhile, when the long side of the push block 322 blocks the oil flow passage 341 of the mandrel 34, the space of the oil outlet cavity 4 is continuously compressed along with the limiting head 354, so that hot oil originally located in the oil outlet cavity 4 flows into the oil flow passage 341 through the oil through hole 343 and is then discharged into the oil flow passage through the oil outlet passage 335;
when oil injection to the oil inlet of the housing 31 is stopped, the spring 355 resets, so that the second supporting portion 431 and the first supporting bracket 342 jointly support the limiting head 354, the first supporting portion 421 supports one side of the washer 351 far away from the sealing sleeve 352, the space of the oil inlet cavity three 43 is compressed, hot oil in the oil inlet cavity three 43 pushes the push block 322 in a direction far away from the core shaft 34, the long side of the push block 322 is separated from abutting with the core shaft 34, and as the cross-sectional area of the long side of the push block 322 is matched with that of the short side of the oil inlet cavity two 42, the hot oil in the oil inlet cavity three 43 cannot flow to the oil inlet of the housing 31 when the long side of the push block 322 moves to the short side of the oil inlet cavity two 42, and the hot oil in the oil inlet cavity three 43 flows into the oil outlet cavity 4 through the oil flowing channel 341 and the oil passing hole 343; and circulating in sequence.
Hot oil flowing into the hot oil channel can gradually fill the whole hot oil channel in a spiral moving mode under the guiding action of the oil guide plate, and heat transfer is carried out on the peripheral side of the roller 1 through the hot oil in the hot oil channel, so that the peripheral side of the roller 1 can be uniformly heated and heated, and the purpose of film coating is achieved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
