The top surface in road is in rolling contact.
In order to further realize the utility model, the periphery of disk roller and guide roller is supported to be respectively provided with eccentric bushing.
In order to further realize the utility model, cylinder is telescopic cylinder.
In order to further realize the utility model, scraper arm positioning sheath is symmetrical arranged on the side wall of rack beam, scraper arm is fixed
Position sheath outer openings, opening are engaged with scraper arm.
In order to further realize the utility model, scraper arm is bend arm.
In order to further realize the utility model, there is gap between the both sides of nut and frame.
The utility model has the beneficial effect that compared to the prior art：
The design of two sides 8 supports disk rollers and 4 guide rollers causes whole frame on the frame of the utility model
Stability and guidance quality are more preferable in the process of walking；All support disk rollers and guide roller at rack cooperation with being fitted with partially
Heart covering device, can be compensated the gap that mechanical wear produces, is improved the use of disk roller with the pressure of on-line control disk roller and track
Service life；Nut and frame coordinate the design that gap is left at front and back sides, effectively prevent copper nut because by uneven radial load and
Cause card resistance caused by leading screw deformation；According to different product combination roll surface actual conditions, by the control of cylinder pressure valve, realize
Scraper and the adjusting of sinking roller face throw-on pressure size.
It is provided by the utility model to be applied to hot galvanizing line zinc pot sink roll scraper mechanism, adapt to zinc pot region high temperature,
The adverse circumstances that zinc gray cadmia seriously adheres to, and can effectively take precautions against the walking card resistance occurred under this operating mode, leading screw deformation, lubrication
Bad and serious wear phenomenon.Have the advantages that compact-sized, maintenance workload is small, standardization level is high, service life is long.
