Embodiment Construction
[0013] like figure 1 and figure 2 As shown in the present invention, a cooling medium-adjustable roll has a cylindrical roll sleeve 1 provided with a long hole 13 in the wall structure between the two ends, and the long hole 13 is in the circumferential direction of the ring section of the roll sleeve 1 at the same There are multiple arrangements in the form of angular distance. And at the tube openings on both sides of the roller sleeve 1, the through holes 21 communicated with the slots are provided corresponding to each slot 13 on the inner tube wall.
[0014] An input end assembly constituting the input end and an output end assembly constituting the output end are respectively sealed and fixed in the cylinder openings on both sides of the roller sleeve 1 . figure 1 Among them, the input end assembly and the output end assembly respectively include a sealing ring 4 that is sealed and fixed to the barrel mouth of the roller sleeve 1, and a rotating part 2 that is sealed ...

The invention relates to a cooling medium adjustable roller, which comprises a tubular roller sleeve. Two ends of the inner side of the roller sleeve is provided with an input end, an output end and a swivel joint interface respectively; the two ends of the roller sleeve are also provided with an input end flow regulating valve and an outlet end flow regulating valve respectively; through holes uniformly distributed are drilled on the tube wall of the roller sleeve along the axial direction; a medium flows to the circumferential through holes through an axial central hole; an input end flow regulating device and an outlet end flow regulating device can simultaneously regulate the flow of the medium; and the outlet end flow regulating device can be independently regulated so as to fulfill the aims of cooling the medium to regulate the surface temperature of the roller and ensuring the surface temperature balance of the roller. Compared with the fluid cooling roller of the prior art, the surface temperature balance, abrasive resistance and service life of the roller are obviously improved; in addition, the cooling medium adjustable roller is difficult to break so as to further improve the usability of the roller; and therefore, the cooling medium adjustable roller has more obvious improvement on both aspects of economic value and use value.
Description
technical field [0001] The invention relates to a roll, more specifically, to a roll with an adjustable cooling medium. Background technique [0002] The rolls of the prior art are affected by external extrusion and material temperature during work, and the temperature of the rolls rises rapidly. How to control the constant temperature of the rolls is a key issue. In the existing design of fluid-cooled rolls, the fluid flows in the inner cavity of the roll to achieve the purpose of cooling. The problem is that because the fluid cannot fill the cavity during cooling, the bottom of the roll is cold and the top is hot. During the rotation process, the roll is cold and hot. Alternate, the faster the speed and the higher the frequency of alternation, the severe rapid chilling of the roll will occur, resulting in breakage of the roll. Contents of the invention [0003] Aiming at the above problems, the present invention provides a roll with adjustable cooling medium, the purpos...
