SUMMERY OF THE UTILITY MODEL
The utility model provides a tungsten carbide corrugating roller that axle head preheats fast aims at solving and adopts to set up the recess at the spindle nose upper surface of connecting axle and carry out the short-term acceleration of axle head preheating speed of heat exchange, nevertheless can pile up in the recess behind steam formation comdenstion water, reduces the problem of spindle nose preheating speed once more.
In order to achieve the purpose, the utility model provides a tungsten carbide corrugated roller with a quickly preheated shaft head, which comprises a corrugated roller drum and connecting shafts arranged at two ends of the corrugated roller drum; wherein:
the middle part of the corrugated roller drum is provided with a cavity, and two ends of the corrugated roller drum are respectively provided with a mounting groove; the two connecting shafts are respectively and fixedly connected to mounting grooves at two ends of the corrugated roller drum, and during assembly, shaft heads of the connecting shafts are just positioned in the mounting grooves; a plurality of parallel narrow and long heat transfer grooves are formed in a shaft head of the connecting shaft, each heat transfer groove comprises a heat exchange end and a flow end, the heat exchange end is arranged on one side close to the corrugated roller, and the flow end is arranged on one side far away from the corrugated roller and communicated with the cavity; and a through hole communicated with the cavity is formed in the middle of any connecting shaft.
More specifically, a siphon is arranged in the through hole and extends to be in contact with the cavity wall of the cavity.
More specifically, a plurality of heat transfer grooves are uniformly distributed on the shaft head of the connecting shaft in a circular ring shape.
The utility model relates to a technical effect of tungsten carbide corrugated roller that spindle nose preheats fast:
the heat conduction efficiency is high; the design that adopts a plurality of evenly distributed's heat transfer groove for the area of the spindle nose department heat exchange of connecting axle increases, and not only can make steam get into the heat exchange end through seting up the end that flows, can make the comdenstion water that forms again in the recess discharge from the end that flows, thereby tungsten carbide corrugating roll bulk temperature can be quick, and even stable rising.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A preferred embodiment of the present invention, which is realized as described above, with reference to fig. 1 to 2, is a tungsten carbide corrugating roll with a rapidly preheated shaft head, comprising a corrugating roll drum 1 and connecting shafts 2 disposed at two ends of the corrugating roll drum 1; wherein:
the middle part of the corrugated roller cylinder 1 is provided with a cavity 101, two ends of the corrugated roller cylinder are respectively provided with a mounting groove, two connecting shafts 2 are respectively and fixedly connected to the mounting grooves at two ends of the corrugated roller cylinder 1, and during assembly, the shaft heads of the connecting shafts 2 are just positioned in the mounting grooves; the shaft heads of the two connecting shafts 2 are respectively fixedly connected with the corrugated roller 1, and a plurality of parallel narrow and long heat transfer grooves 201 are formed in the shaft heads of the connecting shafts 2; the heat transfer grooves are uniformly distributed on the shaft head of the connecting shaft 2 in a circular ring shape and comprise a heat exchange end 202 and a flowing end 203, the heat exchange end 202 is arranged at one side close to the corrugated roller cylinder 1, steam conducts heat at the heat exchange end 202 to preheat the shaft head of the connecting shaft 2, the flowing end 203 is arranged at one side far away from the corrugated roller cylinder 1 and communicated with the cavity 101, and the flowing end 203 is used for inflow of the steam and discharge of condensed water; the middle part of any connecting shaft 2 is provided with a through hole 204 communicated with the cavity 101.
