Abstract

The invention relates to a pollution-free lubrication system of a sewing machine, which comprises a rotating shuttle part and a needle bar part, wherein the rotating shuttle part comprises an oil suction strand, an oil storage felt, a hollow rotating shuttle shaft and a high-speed rotating shuttle mechanism. The pollution-free lubrication system is characterized in that the inner cavity of the hollow rotating shuttle shaft is provided with a gas-oil mixture through hole, the oil storage felt is arranged at the top part of the upper oil tank body of a rotating shuttle sleeve, the bottom side of the oil storage felt is provided with an oil hole and a gas-oil mixture through hole, and the end part of the hollow rotating shuttle shaft is connected with the high-speed rotating shuttle mechanism; and the needle bar part comprises a needle bar, a needle bar sleeve, an oil storage tank and complex lithium grease, wherein the needle bar sleeve is arranged outside the needle bar, the oil storage tank is arranged at the upper end of the needle bar sleeve, and the complex lithium grease is arranged in the oil storage tank. The pollution-free lubrication system can effectively prevent plain lubrication oil from dropping along the need bar to pollute cloth, can be adapted to the lubrication effect reached at a high speed, and can maintain favorable sealing property in the high-speed moving process of the needle bar.

Description

technical field [0001] The invention relates to the technical field of sewing equipment, in particular to a pollution-free lubricating system for a sewing machine. Background technique [0002] At present, whether the computerized embroidery machines on the market have a speed of 800 / min or 1200 / min, the needle bars and hooks used are all aging traditional structures, and only liquid lubricating oil can be used for manual lubrication, and the lubricating oil is sent to At a specific position, or compressed air is blown to the high-speed rotating part to achieve the cooling effect, so it often occurs that lubricating oil drips onto the cloth along the needle rod to cause pollution. In addition, the oil droplets on the hook will also pollute the fabric through the upper thread and the bottom thread; since the hook seat is generally placed under the platen, it is very difficult to regularly inject lubricating oil by hand and it is difficult to control the dosage of lubricating ...
