The invention provides an oil quantity adjustment structure of sewing machine lubricating oil, which belongs to the technical field of clothing manufacturing equipment. It solves technical problems such as unstable oil supply of existing sewing machine lubricants. The oil volume regulating structure includes one-way valve and steady-flow valve; the outlet of one-way valve is connected with the inlet of steady-flow valve, and the steady-flow valve includes valve body and ball. The valve body is provided with installation chamber, the ball is located in the installation chamber, and the pressure regulating spring and steady-flow spring are respectively arranged on both sides of the valve body. The pressure regulating spring is directed towards the inlet of the steady-flow valve, and the pressure regulating spring is directed towards the outlet of the steady-flow valve; the inner wall of the installation chamber is also formed by the pressure regulating spring. The shrinkage of the inlet to outlet diameter of the steady flow valve decreases gradually. The oil quantity regulating structure in the invention cancels the oil quantity regulating screw and other components in the prior art, and adds a simple one-way valve and a flow stabilizing valve to the oil circuit, which can automatically adjust the oil quantity in the oil circuit and improve the oil supply stability of the lubricating oil of sewing machine.

一种缝纫机润滑油的油量调节结构
本专利技术属于服装制造设备
,涉及一种缝纫机,特别是一种缝纫机润滑油的油量调节结构。
技术介绍
缝纫机是用一根或多根缝纫线,在缝料上形成一种或多种线迹,使一层或多层缝料交织或缝合起来的机器。缝纫机能缝制棉、麻、丝、毛、人造纤维等织物和皮革、塑料、纸张等制品,缝出的线迹整齐美观、平整牢固,缝纫速度快、使用简便。缝纫机一般都由送料装置、机座、传动和附件四部分组成,通过各机构的运动合理地配合,循环工作,把缝料缝合起来。缝纫机在工作过程中需要利用润滑油及润滑机构对其进行润滑和降温,通过液体润滑油减小摩擦阻力,减少机械磨损,降低温度,防止锈蚀,减少震动,冲洗摩擦面等。润滑油主要由油泵供油,油泵的动力源来自缝纫机的竖轴,当其转速过高或者过低时缝纫机的润滑油供油量也随着改变,无法达到一个稳定值。竖轴转速过高导致缝纫过程中供油量大,在缝纫过程中经常出现漏油、渗油的情况;转速过低,油泵无法有效工作,供油量减少,无法对机器进行有效润滑。另外在特殊工艺对润滑油的润滑也有较高的要求,例如:机器只进行W缝的工况,机器启停时间短,无法使润滑油到达润滑位置 ...
