Oil leakage preventing mechanism for cloth supply table of sewing machine

Abstract

The invention provides an oil leakage preventing mechanism for a cloth supply table of a sewing machine capable of reliably preventing oil leakage. The oil leakage preventing mechanism comprises an oil scraping part, an oil scraping part support, a sealing plate, a sealing plate support and an oil return part, wherein the oil scraping part is composed of a connection frame, an upper oil scraping claw formed on the upper end of the connection frame and a lower oil scraping claw formed on the lower end of the connection frame, the distance between the upper oil scraping claw and the lower oil scraping claw allows the end part of the cloth supply table to pass through, the oil scraping part support is connected with a sewing machine shell, an installation notch is formed in the oil scraping part support, the oil scraping part is installed in the installation notch of the oil scraping part support, the sealing plate is stored in a storage groove of the sealing plate support, the sealing plate support is connected with the oil scraping part support, a cloth supply table through hole which can be used for the end part of the cloth supply table to pass through is formed in each of the groove walls of two sides of the sealing plate support and the sealing plate, the oil return part comprises an oil return chamber and an oil guide pipe connected with the oil return chamber, and the oil return chamber covers the lower ends of the oil scraping part support and the sealing plate support.

Description

technical field [0001] The invention relates to an oil leakage prevention mechanism of a cloth feeding table of a sewing machine. Background technique [0002] At present, sewing machines are widely used in the garment manufacturing industry, especially industrial sewing machines, which are more widely used in production enterprises that manufacture garments in batches. In such a sewing machine, the cloth feeding table is an indispensable component, and its motion trajectory has multiple degrees of freedom, including forward and backward motion and up and down motion, and needs to penetrate the oil chamber and extend to the oil chamber during the movement. [0003] Therefore, since the cloth feeding table passes through the oil chamber, during the movement of the cloth feeding table, there is a problem that lubricating oil leaks to the clothing through the cloth feeding table to contaminate the clothing. How to prevent lubricating oil from leaking thus becomes an urgent pro...

AI Technical Summary

Problems solved by technology

In the past, in order to solve such problems, the protruding end of the cloth feeding table was sealed by a movable sealing plate, but since the protruding end of the cloth feeding table is movably connected with the sealing plate, there will still be contamination caused by leakage of lubricating oil from the sealing plate clothes problem
