Zipper tooth oxidation line with shafts and bearing seats having longer service lives

Abstract

The invention discloses a zipper tooth oxidation line with shafts and bearing seats having longer service lives, and the zipper tooth oxidation line comprises at least one oxidation tank, wherein each oxidation tank is provided with at least one rotating shaft group; the rotating shaft groups comprise upper shafts and lower shafts that are arranged in parallel; bearing seats are assembled at the two ends of the upper shafts and the lower shafts respectively; the bearing seats are assembled on the oxidation tanks; the lower shafts are assembled in the oxidation tanks; through holes are formed in tank walls of the oxidation tanks; the two ends of the lower shafts penetrates through the through holes and are assembled on the bearing seats respectively; the through holes are provided with mechanical sealing devices; and the lower shafts are assembled at the mechanical sealing devices in a sealing manner. According to the zipper tooth oxidation line, the two end parts of the lower shafts and the bearing seats are arranged outside the oxidation tanks and prevented from being soaked in liquid to be corroded; the service lives of the lower shafts and the bearing seats are prolonged; the maintenance frequency is reduced effectively; the equipment maintenance is easier; the production efficiency is improved; and the costs for purchasing the lower shafts and the bearing seats are lowered.

Description

technical field [0001] The invention relates to a zipper chain tooth oxidation line, in particular to a zipper chain tooth oxidation line with a longer service life for shafts and bearing seats. Background technique [0002] At present, the oxidation equipment used for the oxidation treatment of zipper chain teeth, the inner shaft (i.e. the lower shaft of the present invention) and the bearing seats at both ends of the inner shaft are assembled in the oxidation tank, and the inner shaft and the bearing seats are completely immersed in the liquid. Most of the liquid in the oxidation tank is highly corrosive, so the inner shaft and bearing seat will be corroded after a period of time, and both need to be replaced frequently. 40Cr hard chrome-plated inner shaft has better corrosion resistance than stainless steel shaft, and its price is lower than stainless steel shaft. The inner shafts are formed by self-processing of long rotating shaft sections. The cross-sections of the tw...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a zipper element oxidation line with a longer service life for the shaft and bearing seat, so as to overcome the existing zipper element oxidation line that the lower shaft and bearing seat soaked in liquid are easily corroded, the replacement rate is high, and replacement is difficult And if the upper shaft and the lower shaft are not synchronized, it will easily cause the tape to elongate and break, which will affect the stable production of the oxidation equipment and the tension of the tape.
