The invention provides an oil supply device of a straight-end button hole sewing machine and belongs to the technical field of sewing machines. The problem that lubricating effects of an oil supply lubricating spindle and a spindle sleeve of the traditional straight-end button hole sewing machine are poor is solved. The oil supply device of the straight-end button hole sewing machine comprises a straight-end button hole sewing machine spindle, wherein the spindle is connected with a motor and driven by the motor to rotate; a spindle sleeve is sleeved on the spindle and fixed in a straight-end button hole sewing machine shell; an oil inlet pipe joint and an oil outlet pipe joint are arranged on the spindle sleeve; the oil inlet pipe joint is communicated with the straight-end button hole sewing machine shell through a hose; through a hose, the oil outlet pipe joint is communicated with a nozzle capable of spraying oil to lubricate each moving part in the straight-end button hole sewing machine shell; and an oil driving structure for sucking oil from the oil inlet pipe joint in a vacuum way and supplying oil to the oil outlet pipe joint is arranged between the spindle sleeve and the spindle. According to the invention, the lubricating effect of lubricating oil between the transmission spindle and the spindle sleeve is good and the lubricating oil can be repeatedly used.
Description
technical field [0001] The invention belongs to the technical field of sewing machines, and relates to an oil supply device for a flat buttonhole sewing machine. Background technique [0002] Buttonhole sewing machine is a very important equipment in clothing machinery. Buttonhole sewing machine is referred to as buttonhole machine for short. The buttonhole machine is mainly used to process buttonholes in various clothing. two kinds. During the sewing process, the needle bar of the flat-head buttonhole machine not only moves up and down, but also moves horizontally, so that the sewing needle can penetrate the sewing material at different positions of the needle plate hole, and realize left row and right row , front and rear bartacks for complete buttonhole sewing. The swing performance of the needle bar is very important to the stability of the buttonhole machine. Whether the swing range of the needle bar is reasonable and stable is directly related to the sewing effect of...
