Background
The sewing machine is a machine for sewing materials by sewing threads, and comprises a needle rod mechanism, a thread take-up mechanism, a feeding mechanism, a thread hooking mechanism, a pressing mechanism, a winding device, a lubricating device and the like. The lubricating device of the sewing machine refers to a device for conveying lubricating oil during sewing, and generally, the lubricating oil in an oil pan is conveyed to each movable part of the sewing machine through an oil pump.
Chinese patent document discloses an oil supply device for a sewing machine [ application No.: 200610075234.8; the notice number is: 1865570B ], it is possible to reliably supply lubricant to the inner surface oil supply mechanism and other oil supply mechanisms with a simple structure. An oil guide path from a discharge port of the pump to the oil groove via an oil guide hole of the bearing is connected without branching. A part of the lubricating oil fed to the oil sump is taken in from the oil hole of the main shaft facing the oil sump by the operation of the pump, and each mechanism connected to the main shaft is lubricated by a known inner-face forced oil-feeding mechanism. The remaining lubricating oil, which is not subjected to the inner-surface forced oil supply, is discharged from the oil groove through the discharge hole, the discharge pipe, and the oil jet pipe toward the oil window, so as to confirm whether the oil supply is performed normally. A part of the lubricating oil ejected toward the oil window drops onto the oil receiver, and then the oil drops from the oil hole to a desired position.
Whether normal fuel feeding through the oil window observation, the oil window can become fuzzy under using for a long time on the one hand, lead to the difficult unusual condition of fuel feeding of observing of operator, only enable oil spraying to the oil window at the sewing machine during operation simultaneously, the operator is on using sewing machine its attention all concentrate, the operator generally seldom can be distracted and observe the oil spraying condition in the oil window at the in-process of sewing, can not in time monitor when will causing to lack lubricating oil like this, make sewing machine still work at high speed, wearing and tearing can appear in the condition of lack of oil in operating device among the sewing machine, can cause to scrap when serious.
Disclosure of Invention
The invention aims to provide a sewing machine oil quantity monitoring mechanism aiming at the problems in the prior art, and solves the technical problem of how to automatically and timely monitor abnormal oil supply of a sewing machine.
The purpose of the invention can be realized by the following technical scheme:
