And drawing the polyacrylonitrile carbon fiber precursor to ensure that the precursor reaches the specified fineness.
Because the process for producing the carbon fiber precursor requires that lubricating oil cannot leak from the outlet shaft of the washing roller of the washing machine, even a small amount of leakage can cause great damage to the quality of the carbon fiber precursor, so that the product is unqualified. At the same time, the equipment must be stably operated for a long time, and the bearings must be lubricated by circulating oil. Moreover, because the washing roller is large in size and heavy in weight, the disassembly is extremely inconvenient, and the production line cannot stop at any time and only can stop in a planned way, the sealing mode which needs to be maintained, such as a contact type framework oil seal, is not applicable. Another type of non-contact seal is usually a labyrinth seal, and the sealing structure does not have contact wear of parts, but because of gaps, even if there are more labyrinths, oil and oil gas still can flow into the labyrinth grooves from the non-contact gaps, and then leak out gradually along the axial direction. Therefore, a shaft sealing structure of a washing roller of a carbon fiber washing machine must be found to meet the special requirements of carbon fiber precursor production.

Drawings
FIG. 1 is a schematic diagram of a structure of the present utility model;
fig. 2 is an enlarged view at a in fig. 1.
In the figure: 1. the oil thrower comprises a shaft sleeve, a bearing seat, a bearing, a box body, an oil thrower, an outer end cover, a washing roll shaft, an oil filler hole and an oil return hole.
Detailed Description
Specific embodiments of the utility model are described further below in order to facilitate a further understanding of the utility model by those skilled in the art without limiting the scope of the claims thereto.
Referring to fig. 1, an end sealing device of a washing roll shaft of a carbon fiber washing machine comprises a bearing arranged between the washing roll shaft and a box body, wherein a bearing seat is arranged between the bearing and the box body, an outer end cover is arranged on the bearing seat, an oil thrower fixedly arranged on the outer circumferential surface of the washing roll shaft is arranged between the outer end cover and the bearing, and an annular convex edge propping against an outer ring of the bearing is arranged on the outer end cover; a sealing mechanism is arranged between the outer end cover and the outer circumferential surface of the washing roll shaft;
