Multifunctional ejector rod device for pneumatically disassembling rubber rollers

Abstract

The invention relates to a multifunctional ejector rod device for pneumatically disassembling rubber rollers, and belongs to the technical field of spinning assisting devices. The multifunctional ejector rod device comprises an ejector rod, a steel needle, a pressing gasket and the like, and is characterized in that the ejector rod is formed by a large diameter rod body and a small diameter rod body; the diameter of the small diameter rod body is 17.5 mm, and the steel needle is installed at the axis portion of the end of the small diameter rod body and extends out of the end of the small diameter rod body by 5 mm; an arc groove is formed in the end of the small diameter rod body; an insertion opening is formed in one side of the pressing gasket, and the width of the insertion opening is 0.5-1 mm larger than the outer diameter of an upper roller bearing. According to the multifunctional ejector rod device, as blocked bulkhead oil holes in rubber-roller bulkheads can be dredged in the process of disassembling the rubber rollers, great convenience is brought to oiling maintenance of the rubber rollers in the following working procedures, and the disassembling requirements of various-specification rubber tubes can be met. The multifunctional ejector rod device is simple in structure and convenient to operate, and the problems that in the prior art, only the single rubber-roller ejection function exists, normal use can be carried out only by detecting, adjusting and dredging the bulkhead in the following process, and the working efficiency is seriously influenced are solved.

Description

technical field [0001] The invention relates to a multi-functional ejector device for a pneumatic skin-removing roller, which belongs to the technical field of textile auxiliary equipment. Background technique [0002] The diameter of various rubber rollers in spinning mills will become smaller after being used for a long time, and they must be unloaded and then re-set to meet the use requirements. The ejector pin of the existing pneumatic cover roller machine has a single function, and can only eject the top roller bearing from the rubber roller, and the outer diameter of the ejector rod is too large, so that the withdrawn rubber hose cannot be quickly separated from the lower end of the ejector rod , especially the unloading of the double-layer rubber roller, not only the operation is very inconvenient, but also need to check whether the bulkhead is skewed and whether the oil hole of the bulkhead is blocked after unloading, but it can be put into use after adjustment and d...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a multi-functional ejector device for pneumatic roller retraction that can quickly withdraw and unload rubber rollers, without the need for subsequent inspection and adjustment, dredging of boring ends, simple structure, convenient operation, and improved work efficiency; to solve the problem of existing ejectors There is only a single function of ejection, and the outer diameter is not suitable, resulting in slow unloading speed and inconvenient operation. Follow-up inspection and adjustment are required to clear the stuffy head, which seriously affects work efficiency.
