Water circulation sealing component on trunk-type rewinding machine

Abstract

The invention relates to a water circulation sealing component on a trunk-type rewinding machine. The water circulation sealing component on the trunk-type rewinding machine comprises a main shaft, wherein one end of the main shaft is provided with a circulation water intake and drainage section; the circulation water intake and drainage section along the peripheral direction of the main shaft is provided with an annular water inlet groove and an annular water outlet groove respectively; the annular water inlet groove and the annular water outlet groove are internally provided with a circulation water inlet and a circulation water outlet respectively. The water circulation sealing component on the trunk-type rewinding machine is characterized in that the circulation water intake and drainage section of the main shaft is provided with a rear sealing seat and a front sealing seat through bearings; a middle sealing seat is arranged between the front sealing seat and the rear sealing seat; the front sealing seat is provided with a water intake connection hole communicated with the annular water inlet groove; the rear sealing seat is provided with a water drainage connection hole communicated with the annular water outlet groove; inner cavities between the front sealing seat and the main shaft and between the rear sealing seat and the main shaft are internally provided with mechanical sealing elements respectively. The water circulation sealing component on the trunk-type rewinding machine, which is provided by the invention, has a favorable sealing effect, and can effectively guarantee the normal and safe operation of the rewinding machine and the normal production process.

Description

technical field [0001] The invention relates to a water circulation sealing part, in particular to a water circulation sealing part on an elephant trunk type wire take-up machine, and belongs to the technical field of metal drawing equipment. Background technique [0002] Elephant trunk wire take-up machine is a wire take-up mechanism suitable for linear wire drawing machine and pulley type wire drawing machine. , and then through the guide wheel set on the rotating disk, the straightener and then wound onto the reel. After the whole machine is started, the elephant trunk type wire take-up machine is started, and the steel wire is evenly adjusted from the reel to the elephant trunk type lower wire arm and falls on the drop frame. After normal operation, it is not necessary to stop until the drop frame is full of wires. [0003] Existing elephant trunk type take-up machine is because steel wire can generate heat in the take-up process, so the main shaft and reel of take-up m...

AI Technical Summary

Problems solved by technology

A water inlet sleeve is set on the water inlet and the water outlet, and the seal between the water inlet and the water outlet is realized by the mechanical seal on the water inlet sleeve. Because the main shaft handles the rotation state when it is working, the sealing effect of the mechanical seal is poor.
