Oil supply structure and oil supply method of sewing machine

Abstract

The invention relates to an oil supply structure and oil supply method of a sewing machine. The oil supply structure comprises an oil tank, an oil inlet pipeline, an oil conveying pipeline, an oil core, an oil return pipeline and an engine oil transfer platform; an engine oil transfer area is formed by the upper surface of the engine oil transfer platform and the wall face of the oil tank; the engine oil transfer area is provided with a self-flowing channel communicated with the lower portion of the oil tank; the oil absorption end part of the oil core is immersed in engine oil in the engine oil transfer area in a freely drooped manner; and the height of the oil absorption end part immersed in the engine oil is h3, and the outer diameter of the oil absorption end part is d, wherein h3 is greater than or equal to 0.2 d and less than or equal to 0.5 d. Oil supply of the oil core can be implemented during flowing of the engine oil, it is ensured that lubricating oil has a good lubricating effect, and once oil supply is stopped, the oil absorption end part of the oil core contains a small amount of the engine oil or does not contain the engine oil, so that the oil core does not supply oil continuously, the damage to the sewing material quality due to leakage of the engine oil is avoided, meanwhile, the waste of the engine oil is avoided, and the oil can be conveniently supplied to the sewing machine when the sewing machine works next time.

Description

technical field [0001] The invention belongs to the field of sewing machines, and in particular relates to an oil supply structure of a sewing machine, and also relates to an oil supply method of a sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. Because the driving parts that drive the sewing needle are in continuous and repeated motion, in order to protect the moving parts on the sewing machine and ensure the normal operation of the sewing machine, it is necessary to deliver oil to the parts that need to be lubricated on the sewing machine through the oil supply structure. [0003] At present, the existing oil supply structure includes a fuel tank, an oil inlet pipeline connected to the fuel tank, an oil delivery pipeline, and an oil wick arranged in the oil delivery pipeline, wherein the oil wick i...

AI Technical Summary

Problems solved by technology

[0005]1. Since the sewing machine oil has a certain viscosity, it will deposit at the bottom of the oil tank. Therefore, it is difficult to guarantee the quality of the supplied machine oil and cannot achieve the required lubrication effect, and after long-term use, it will cause damage to the sewing machine;

[0006]2. Regardless of the status of the sewing machine, the oil wick is always in the oil-absorbing mode. Material or leather pollution, affecting the quality of sewing products, but also caused a waste of oil
