Description
Technical field
The invention belongs to technical field of sewing equipment, it is related to a kind of lubrication knot of looper slide bar on sewing machine and sewing machine
Structure.
Background technology
Sewing machine is to use one or more sewing thread, and one or more stitching is formed on sewing, stitches one or more layers
The machine that material interweaves or unites by a seam.Fabric and leather, plastics, the paper such as sewing function sewing cotton, fiber crops, silk, hair, staple fibre
Deng product, the stitching neat appearance stitched out, it is smooth firmly, sewing velocity is fast, easy to use, therefore is used widely.Sewing
Upper looper on machine is a part in sewing machine, and the upper looper of sewing machine is connected on slide bar, and slide bar is in high-speed motion mistake
There is abrasion and produce substantial amounts of heat in Cheng Zhonghui, it is therefore desirable to which enough lubricating oil is lubricated and lowers the temperature to it, ensureing
Sewing machine normal work.Current method is to set food tray in bottom of shell, the liquid lubricant of flowing is stored in food tray, then lead to
Cross oil pump and supply lubricating oil to slide bar position.But the quantity delivered of lubricating oil is difficult to be precisely controlled in this structure, if lubrication
Oil is very few, does not have due lubrication and cooling-down effect；If lubricating oil is excessive, unnecessary lubricating oil can be caused with slide bar
Move and outwards spill, and then pollute suture and sewing.
China's patent (notification number：CN201068513；The day for announcing：2008-06-04) disclose a kind of overedger curve-needle
Slider lubrication device, slide bar vertically runs through sliding block, and slide bar bottom is vertically formed with the blind chamber of accommodating oil line, is laterally formed with through hole, leads to
Hole connects with blind chamber.It is located at below sliding block upper surface in through hole up stroke, the crank top being connected with slide bar by pivot pin is equipped with
Oily line, oily line is touched with crank upper side；The embedded steel loading silk of oily line, the other end of oily line is installed in casing, by the logical of slide bar
Hole carries out fuel feeding to sliding block, and lubricating oil is supplied slide bar outer wall by sliding block again.
The lubricating oil of liquid is supplied by slide bar outer wall by oily line in above-mentioned patent document, lubricating oil is difficult to control, just
Oil mass in phase oil line is easily oozed when more, and the oil mass after long-time use in oily line tails off, and slide bar is waited less than fully profit again
It is sliding, influence lubricant effect.
The content of the invention
A kind of above mentioned problem that the present invention exists for existing technology, there is provided the lubrication knot of looper slide bar on sewing machine
Structure, the technical problems to be solved by the invention are：Ensure lubricant effect while how effectively preventing lubricating oil from leaking outside.
The purpose of the present invention can be realized by following technical proposal：
A kind of lubrication system of looper slide bar on sewing machine, sewing machine includes casing, slide bar and sliding block, is opened on the sliding block
The through hole for running through is provided with, the sliding bar is plugged in the through hole, it is characterised in that the lubrication system includes being arranged on
Fuel reserve tank and the immersion oil part for being soaked with grease on the casing, are filled with grease, the bottom of the fuel reserve tank in the fuel reserve tank
Oil-out is offered, one end of the immersion oil part is located at the oil-out of the fuel reserve tank, the other end direction of the immersion oil part
The outer peripheral face of the slide bar.
Its principle is as follows：Immersion oil part is impregnated with lubricant grease in advance, when sewing machine runs, slide bar in the through hole of sliding block on
Reciprocal high-speed motion down；One end of immersion oil part extends close to the outer peripheral face of slide bar, and the end of immersion oil part can be slide bar fuel feeding, from
And slide bar is lubricated, it is ensured that the normal work of machine.Simultaneously after the grease on immersion oil part is consumed, the oil in fuel reserve tank
Fat is supplemented by being applied on immersion oil part of producing of capillarity, to ensure prolonged lubrication.Entirely moving
During lubricate behavior and there is no liquid lubricant to participate in such that it is able to effectively prevent lubricating oil in slide bar motion process to leaking
Leak and the phenomenon of pollution suture and sewing occur, while immersion oil part can obtain continual grease supplement, it is ensured that immersion oil
The long-time lubricating ability and good lubricant effect of part.
On the above-mentioned sewing machine in the lubrication system of looper slide bar, cavity is offered on the casing, the slide bar
Lower end is located in the cavity, and the swing arm that can be swung is provided with the cavity；Under the end of the swing arm and the slide bar
End is hinged and swing arm swings and the slide bar can be driven to move back and forth up and down.Slide bar band moving slide-bar is acted；Immersion oil part is located at envelope
In the cavity for closing, grease is not volatile, while immersion oil part will not also produce impurity during grease is passed into slide bar, enters one
Step ensure that lubricant effect.
On the above-mentioned sewing machine in the lubrication system of looper slide bar, end face and institute of the immersion oil part towards the slide bar
Stating has gap between slide bar outer peripheral face.Do not contacted between immersion oil part and slide bar, this avoid friction, between the two with compared with
Small spacing, slide bar is not directly contacted with immersion oil part, when slide bar high-speed motion, can produce micro trail change, now with
The grease on immersion oil part surface has trickle contact, and grease is taken on slide bar.Meanwhile, during slide bar high-speed motion, empty cavity temperature liter
Height, grease volatile molecular, with the air current flow of air, is attached to slide bar surface, so as to be lubricated to slide bar.If with leaching
Oily part directly contact, over time, immersion oil part can be deformed upon, and lubricant effect is substantially reduced.
On the above-mentioned sewing machine in the lubrication system of looper slide bar, alternatively, the immersion oil part is towards institute
The end face for stating slide bar is in contact with the outer peripheral face of the slide bar.It is right on slide bar that grease so on immersion oil part can be acted directly on
It is lubricated.
On the above-mentioned sewing machine in the lubrication system of looper slide bar, the malthoid for being soaked with grease is installed with the casing,
The malthoid is located at the lower section of the slide bar, and one end of the malthoid is stretched into the cavity and towards the lower end of the slide bar.
Slide bar can be in contact when moving down with the malthoid, and slide bar is lubricated from different azimuth by the malthoid, lifting lubrication
Effect.
On the above-mentioned sewing machine in the lubrication system of looper slide bar, the lower end of the slide bar is also soaked with the oily line of grease,
The oily line is set in the end of the slide bar.Oily line is moved with slide bar, at any time between slide bar and sliding block and slide bar and pendulum
The junction of arm is lubricated, it is ensured that lubricant effect.
On the above-mentioned sewing machine in the lubrication system of looper slide bar, the immersion oil part is fabric by malthoid, felt or nonwoven
Into.Malthoid, felt and non-woven fabrics have good grease absorption property, it is ensured that the reliable lubricant effect of long-time stable.
A kind of sewing machine is also provided in the present invention, the sewing machine has above-mentioned lubrication system.
Compared with prior art, the present invention has advantages below：
1st, there is no liquid lubricant to participate in the lubrication behavior of slide bar in the present invention, but be lubricated using grease, change liquid
State oil lubrication is grease lubrication, without oil leakage phenomenon when ensure that slide bar high-speed slide, effectively prevent suture and sewing
Contaminated phenomenon.
2nd, the grease of immersion oil part can be supplemented timely and effectively after being consumed in the present invention, keep prolonged lubrication
Ability, so as to ensure that lubricant effect of the lubrication system to slide bar.
