Description
Technical field
The invention belongs to the sewing machine technique field, relate to a kind of fueller of flat head keyhole sewing machine.
Background technology
Button holing sewing machine is very important a kind of equipment in the garment machinery, and button holing sewing machine is called for short lockstitch button holder, and this lockstitch button holder is mainly used in processing the buttonhole in all kinds of dress ornaments, is divided into two kinds of straight buttonholing machine and eyelet buttonhole sewing machines.The shank of straight buttonholing machine except moving up and down, also will be done horizontal balancing point motion in the process of making, make sewing needle thrust sewing at the diverse location in needle plate hole, realizes left line, right line, front and back noose, makes to finish complete buttonhole.It is very important for the stability of lockstitch button holder work that shank swings performance, and whether the shank amplitude of fluctuation with the quality of lockstitch button holder sewing efficiency and the height of fault rate has direct relation rationally with stable.
Development along with lockstitch button holder, existing lockstitch button holder generally all adopts motor-driven, then the transmission main shaft that is arranged in the lockstitch button holder casing stretches out housing and links to each other with motor, the other end of transmission main shaft then links to each other with each mechanism of lockstitch button holder, and finishes worker's energy of lockstitch button holder for each mechanism the power transmission of motor.
In above-mentioned structure, because stretching out casing, the transmission main shaft of lockstitch button holder links to each other with motor, transmission main shaft can relative to rotating with casing, will wear and tear to transmission main shaft so so.Existing generally is by be provided with a supporting seat that is set on the transmission main shaft between transmission main shaft and casing, in order to increase the lubricity between transmission main shaft and the supporting seat inwall, be provided with felt at the supporting seat inwall, then by keep the lubricating oil between supporting seat inwall and the transmission main shaft to the irregular interpolation lubricating oil of felt.This lubricating oil also can bring each motion with lubricating oil along with the motion of transmission main shaft, plays lubricated effect.Although the lubrication system of this structure can reduce the wearing and tearing of transmission main shaft,, need artificial interpolation lubricating oil, and lubricating oil can't reuse, hair bores also can exist wearing and tearing, has so also increased maintenance cost.
Summary of the invention
The objective of the invention is to have the problems referred to above for existing technology, proposed that a kind of lubricating oil can be reused and lubricated flat head keyhole sewing machine in each motion lubricant effect fueller of flat head keyhole sewing machine preferably.
Purpose of the present invention can realize by following technical proposal: a kind of fueller of flat head keyhole sewing machine, comprise the flat head keyhole sewing machine main shaft, described main shaft links to each other with motor and is rotated by driven by motor, a sheathed axle sleeve and this axle sleeve are fixed in the flat head keyhole sewing machine casing on main shaft, it is characterized in that, be provided with inlet connector and flowline connection to subsea at axle sleeve, described inlet connector is connected with the flat head keyhole sewing machine oil sump by flexible pipe, described flowline connection to subsea is connected with the nozzle of each moving component in the energy jet lubrication flat head keyhole sewing machine casing by flexible pipe, is provided with between axle sleeve and main shaft by vacuum from the inlet connector oil suction and to the moving structure of the oil of flowline connection to subsea fuel feeding.
The fueller of this flat head keyhole sewing machine mainly is a sheathed axle sleeve on main shaft, axle sleeve is provided with inlet connector and flowline connection to subsea, inlet connector is connected with the flat head keyhole sewing machine oil sump by flexible pipe, flowline connection to subsea is connected with the nozzle of each moving component in the energy jet lubrication flat head keyhole sewing machine casing by flexible pipe, lubricating oil flows back to the flat head keyhole sewing machine oil sump and forms the oil circulation behind each moving component of nozzle ejection, between axle sleeve and main shaft, be provided with the moving structure of oil, the moving structure of this oil will enter between transmission main shaft and the axle sleeve from the inlet connector oil suction by the mode of vacuum, and the lubricating oil of inspiration is sent from flowline connection to subsea.
In the fueller of above-mentioned flat head keyhole sewing machine, described axle sleeve comprises the body of a ring-type, on an end face of body, with this body by integral forming eccentric operate portions is arranged, above-mentioned inlet connector and flowline connection to subsea lay respectively on the external cylindrical surface of operate portions, and described inlet connector and flowline connection to subsea are connected with the eccentric orfice of operate portions respectively.The same center of circle of the spliced eye of the body transmission main shaft of the eccentric orfice of this operate portions and axle sleeve arranges, and this axle sleeve is fixed on the casing by body.
In the fueller of above-mentioned flat head keyhole sewing machine, the moving structure of described oil is included on the axle sleeve between inlet connector and the flowline connection to subsea and offers through hole, in through hole, be provided with the plunger that in through hole, to do reciprocal first motion, end in contact on the periphery wall of above-mentioned main shaft in the described plunger, offer the spring fitting blind hole on the outer face of plunger, be provided with spring in the described spring fitting blind hole, with the contacted main shaft periphery wall of plunger on offer one section oil suction groove along the circumferential direction of main shaft.This through hole runs through the thicker eccentric hole wall of axle sleeve operate portions, the lower end abutment of plunger main shaft oil suction groove bottom land when plunger is arranged in through hole, when main shaft in when motion, the oil suction groove of main shaft periphery wall move to through hole over against the time, the spring of plunger outer end abuts against plunger the inner of plunger is resisted against oil suction groove bottom land, air in the oil suction groove extruded by flowline connection to subsea make the oil suction groove in axle sleeve, form vacuum, carry out the vacuum oil suction by inlet connector during main shaft rotation process inlet connector, lubricating oil sucks and exists in the oil suction groove, when main shaft rotation process flowline connection to subsea, by stretching into of plunger lubricating oil in the oil suction groove is sent by flowline connection to subsea.
