Abstract
The present invention is method of preventing needle bar in sewing machine from throwing lubricant oil and relates to a scheme of raising the part quality and function of industrial sewing machine. Sputtering preventing container and hydraulic pump are utilized to pump the lubricant oil flowing out along the surface of the needle rod back to the sewing machine casing via the inside cavity of the needle rod. The method has smart design, reasonable structure, easy realization and low cost.
Description
The present invention relates to improve the technological innovation scheme of industrial sewing machine part quality and function, particularly utilize anti-container and the hydraulic pump of spilling by the method that prevents throwing lubricant of needle bar in sewing machine of needle bar of sewing machine inner chamber in will be from the lubricating oil pumpback that flows down along the shank outer surface in the sewing casing to former casing.
Along with the raising of people to the clothes quality requirement, garment enterprise is also more and more harsher to the quality requirement of Sewing machines.In order to enhance productivity, sewing velocity surpassed 5000 pins/minute, raising along with Sewing machines speed, the lubrication machine part seems extremely important, is satisfying under the situation of service life of a machine, has lubricating oil and is taken out of the casing outside by the shank of high speed back and forth movement, flow down along the shank outer surface, collection deposit a certain amount of after, just can be got rid of and fall on the dress material of making by shank, the enterprise that give to produce clothes causes certain loss.
At present, the problem of high speed sewing machine needle rod lubricant throwing, just perplexing the enterprise that produces high speed sewing machine both at home and abroad, become the technical barrier of further raising Sewing machines complete machine quality, by data searching and inquiry relevant enterprise, still do not have a kind of gratifying technical scheme and solve this technical barrier, referring to " Xi'an industrial enterprise difficult problem project volume " or Xi'an economy net, the bid of the technical barrier of Xian Standar Industrial Joint-stock Co., Ltd.
At above-mentioned technical barrier, the purpose of this invention is to provide and a kind ofly utilize anti-container and the hydraulic pump of spilling, prevent throwing lubricant of needle bar in sewing machine by the method for needle bar of sewing machine inner chamber in will be from the profit oil pumpback that flows down along the shank outer surface in the Sewing machines casing to former casing.Use it, not only prevented throwing lubricant of needle bar in sewing machine but also made profit oil to circulate, thus can be as far as possible during for sufficient machine parts running to moistening the demand of oil; And cost is low, and is simple, can negative effect do not arranged to the quality function of original machine parts and complete machine simultaneously.That is to say as long as on original needle bar of sewing machine, carry out simply and reasonably transforming and installing other accessory.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes in the following way:
A kind of method that prevents throwing lubricant of needle bar in sewing machine, the steps include: to take off original-pack needle bar of sewing machine or get one and be equipped with shank, with mantle fiber on this needle bar of sewing machine the higher authorities inwall, the most inwalls of shank the higher authorities of present various Sewing machines products do not have mantle fiber, if existing mantle fiber, certainly needn't overlap again, directly utilize to get final product; At hydraulic pump of the inner installation of this needle bar of sewing machine, the depression bar of the hydraulic pump of being installed and the higher authorities of this shank leave the certain space distance; On described needle bar of sewing machine, near making a call to an aperture above the hydraulic pump cylinder body of being installed; A piston is installed above the depression bar of the hydraulic pump of being installed, is added a piston-cylinder at the piston of being installed; The higher authorities that seal described needle bar of sewing machine with screw have also fixed the piston-cylinder installed and the scope of activities of piston simultaneously; In described needle bar of sewing machine bottom aperture is set, the hydraulic pump of itself and shank inside is linked.An anti-container that spills is installed at set aperture place, bottom.So just make the lubricating oil that flows down from needle bar of sewing machine be introduced into the anti-container that spills very dexterously; Almost simultaneously absorbed this shank inner chamber, be discharged in the casing by the top aperture by the pressure of described piston by hydraulic pump.
The present invention only installs an anti-container that spills and with its inner chamber a hydraulic pump and a piston is installed owing to utilized the existing sewing machine shank in its bottom; An oil outlet and a fuel feed hole are set thereon, down respectively; Seal its upper port, can prevent that needle bar of sewing machine from getting rid of lubricating oil.It is ingenious, rational in infrastructure that the present invention has design, uses the present invention bring negative effect can for other parts, greatly improved the complete machine quality of Sewing machines.
Machine work principle of the present invention is: needle bar of sewing machine is when motion, the piston that is contained in its inner chamber also and then moves up and down, the motion of this piston can in time drive the hydraulic pump works that is installed in the needle bar of sewing machine again, the anti-timely inspiration shank inner chamber of oil that spills in the container will be entered into, and under the pressure effect of this piston, be discharged in the Sewing machines casing.
Use of the present invention is just carried out simple machining and a small amount of accessory is installed former needle bar of sewing machine, can reach to prevent that lubricating oil from being got rid of on the dress material of falling in the making by shank.Thereby the problem of existing throwing lubricant of needle bar in sewing machine is able to basic solution.
Claims (3)
1, a kind of needle bar of sewing machine that prevents gets rid of the method for lubricating oil, it is characterized in that: utilize anti-container and the hydraulic pump of spilling by the needle bar of sewing machine inner chamber, the lubricating oil pumpback that will be in the sewing casing flows down along the shank outer surface is in former casing.
2, get rid of the method for lubricating oil by the described needle bar of sewing machine that prevents of claim 1, it is characterized in that, utilize the anti-container that spills to receive from the oil that the shank outer surface flows down, almost be withdrawn in the original casing through the shank inner chamber by hydraulic pump simultaneously.
3, get rid of the method for lubricating oil according to claim 1 or the 2 described needle bar of sewing machine that prevent, it is characterized in that: the oil that flows down from the Sewing needles rod outer surface is provided with by certain, flows to this shank inner chamber, is discharged in the original casing again.Certainly, easy piston pump and non-return valve are set in shank, the method with hydraulic pump principle effect is also in the scope of the present invention.
