Abstract
The invention discloses a needle bar oil return mechanism of a sewing machine. The needle bar oil return mechanism comprises a machine casing, a needle bar and a needle bar sleeve. The needle bar is in sleeved connection with the needle bar sleeve and is assembled on the machine casing. An oil scraping assembly and annular oil cotton are arranged on the lower portion of the needle bar sleeve, the oil scraping assembly is fixed to the machine casing and axially movably matched with the needle bar, the oil cotton is located below the oil scraping assembly, and an oil absorbing assembly for conveniently sucking oil stain on the oil cotton is further arranged below the oil cotton. The oil scraping assembly is arranged below the needle bar sleeve, which is equivalent to that the needle bar is provided with two oil-proof measures, and the oil-proof effect is better compared with a previous single oil-proof measure. The oil scraping assembly is formed by two oil scraping oil seals at intervals; and compared with a single oil scraping oil seal, the oil is scraped more cleanly, and the oil scraping effect is better. The oil absorbing assembly is arranged below the annular oil cotton, the problem that because the annular oil cotton stores too much oil stain, the oil absorbing effect is affected is solved, and the oil absorbing effect of the annular oil cotton is maintained at every moment. The invention belongs to the technical field of sewing machine oil leakage prevention.
Description
Technical field
The invention belongs to Sewing machines oil-leakage-prevention technical field, more particularly, it relates to a kind of needle bar of sewing machine oil return mechanism.
Background technology
One or more sewing thread used by Sewing machines, and sewing is formed one or more stitchings, makes the machine that one or more layers sewing interweaves or unites by a seam.Sewing function make cotton, fiber crops, silk, hair,
artificial fibredeng fabric and leather,
plastics, the goods such as paper, the stitching neat appearance of stitching out, firmly smooth, sewing velocity is fast, easy to use.General Sewing machines all by head,
support,
transmissionwith
annexfour part compositions.Head is the major part of Sewing machines, and it forms by stinging material, hook line, take-up, feeding four mechanisms and coiling, binder, Luo Yadeng auxiliary body, and the motion of each mechanism reasonably coordinates, and periodic duty unites by a seam sewing.
The shank of overlock machine is due in above-below direction high-speed driving, therefore lubricating oil must be had in case stop machine tool is subject to frictional heat impact and damaged and carry out at a high speed pleat swimmingly and move, now, in order to prevent from being supplied to above-mentioned shank and complete the oil leak pollution sewing object of lubrication and arrange recovering mechanism.The needle rod oil-returning of existing overlock machine is divided into half-packaging and full-enclosed, and half-packaging needle rod oil-returning adopts half block oil cotton to contact oil return with shank is latter half of, and first half oil cannot be absorbed; Existing full-enclosed needle rod oil-returning, although adopt, annular oil is cotton to be encased completely by shank, but still cannot reach oil return effect in time when oil mass is excessive, oil is had to throw away, and existing full-enclosed needle rod oil-returning mounting means is that shank cover is connected with return tray buckle, lack radial location, loosening easily appears when running up in machine.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide and a kind ofly prevent fluid from splashing and can the needle bar of sewing machine oil return mechanism of oil return.
For achieving the above object, the invention provides following technical scheme: a kind of needle bar of sewing machine oil return mechanism, comprise casing, shank, shank cover, described shank and shank are socketed and are assemblied on casing, the below of shank cover is provided with frizing assembly, annular oil is cotton, and described frizing assembly is fixed on casing, and frizing assembly coordinates to activity with needle road axis, oil cotton is positioned at below frizing assembly, and the below of oil cotton is also provided with the oil suction component being convenient to the oil stain on oily cotton to siphon away.
Described frizing assembly comprises frizing oil sealing, and frizing oil sealing is provided with axially extending bore, and the outer diameter shape size of described through hole and shank all matches.
Described frizing oil sealing is two groups, in be axially arranged in juxtaposition and between be provided with gap.
Described oil suction component comprises oil drain pan, suction pipe and oil pump, and oil drain pan, for catching the oil stain on annular oily cotton, communicates through oilhole between oil drain pan with suction pipe.
Described oil drain pan and shank overlap snapping and are spirally connected with casing.
Described annular oil is cotton is oil return felt.
The beneficial effect of needle bar of sewing machine oil return mechanism of the present invention is: adopt increase activity frizing oil sealing on the oily cotton of annular, part oil can scrape off by this movable frizing oil sealing while moving up and down along with shank, siphoned away by oily cotton, remaining a small amount of oil is directly siphoned away by oily cotton, realize Double-protection, avoid shank and get rid of oily phenomenon, utilize oil pump to force the oil on oily cotton to siphon away simultaneously, guarantee the oil absorption that oil is cotton to improve oil return effect.
1, be provided with frizing assembly in the below of shank cover, be equivalent to shank and be provided with the grease proofing measure of twice, the grease proofing better effects if of the single track before comparing.
2, frizing assembly is made up of two frizing oil sealing intervals, and compare single frizing cleaner, frizing effect is better.
3, be provided with oil suction component in the below that annular oil is cotton, avoid storing too many oil stain because annular oil is cotton and affects oil absorbing effect, the oil absorbing effect that the moment keeps annular oil cotton.
Accompanying drawing explanation
Fig. 1 is phantom of the present invention.
Fig. 2 is part exploded perspective view of the present invention.
Reference numeral: 1, casing, 2, shank, 3, shank cover, 4, frizing assembly, 5, annular oil is cotton, 6.1, oil drain pan, 6.2, suction pipe, 6.3, oil pump.
Detailed description of the invention
Referring to figs. 1 through Fig. 2, needle bar of sewing machine oil return mechanism embodiment of the present invention is described further.
Existing shank is only provided with an annular oil cotton, and easy storing excess fluid after oil suction, the oily cotton oil absorbing effect of single annular is limited in addition, so a kind of needle bar of sewing machine oil return mechanism of the present invention, comprise casing 1, shank 2, shank cover 3, described shank 2 overlaps 3 with shank and is socketed and is assemblied on casing 1, the below of shank cover 3 is provided with frizing assembly 4, annular oil cotton 5, described frizing assembly 4 is fixed on casing 1, frizing assembly 4 and shank 2 are axially movable to be coordinated, oil cotton is positioned at below frizing assembly 4, the below of oil cotton is also provided with the oil suction component being convenient to the oil stain on annular oil cotton 5 to siphon away.Described frizing assembly 4 comprises frizing oil sealing, and frizing oil sealing is provided with axially extending bore, and the outer diameter shape size of described through hole and shank 2 all matches.
