Technical Field

The invention relates to the technical field of spinning, in particular to a centralized oil supply and lubrication system for spindles of a spinning frame.

Background

The spinning machine is a spinning machine which spins the roving made by the previous spinning process into spun yarn bobbin yarn through the links of roller drafting, spindle twisting, ring winding and the like, each spinning machine is provided with hundreds to thousands of sets of spun yarn spindles, and the production scale of a spinning mill is represented by the total number of the spindles provided with the spinning machine. The spun yarn spindle is a combined piece which takes a slender revolving shaft supported by two points as a main body and generally comprises a spindle blade, a spindle disc and a spindle seat, the spindle blade and the spindle disc are matched to form a combined body, the lower part of the spindle blade is inserted into an inner cavity of the spindle seat to form a whole set of spindle, the spindle is driven to run at a high speed by a mechanical transmission system of a spinning machine, a bobbin is sleeved on the spindle blade and driven to run at a high speed by the spindle to realize twisting and winding functions, and the rotating speed of the spindle is generally 10000-20000 revolutions per minute. The spindle seat is internally composed of an upper supporting bearing, a lower supporting bearing and a damping vibration attenuation element, when the spindle works, lubricating oil with a certain height is added into an inner cavity of the spindle seat to lubricate the upper bearing and the lower bearing so as to reduce friction and wear generated when the spindle blade rotates, and meanwhile, the spindle seat plays a role of a damping medium. After the spindle works for a certain time, the lubricating oil in the spindle seat is reduced, and the spindle needs to be periodically replenished with oil so as to keep enough lubricating oil to lubricate the spindle bearing.

In the prior art, when lubricating oil is added to a spindle, a combined part of a spindle blade and a spindle disc needs to be pulled out from a spindle seat, then lubricating oil is injected from a bearing orifice at the upper end of the spindle seat one by using a spindle oiling machine or a small oil pot, the oil quantity of oil supplement has strict requirements, the lubricating oil can be thrown out to pollute yarns when the oil supplement is too much, and the purpose of maintaining the lubrication cannot be achieved when the oil supplement is too little. The lubricating oil adding mode can not timely and directionally supplement lubricating oil to the spindle seat which is short of lubricating oil, only general oiling can be carried out, and phenomena of lubricating oil addition leakage and lubricating oil addition shortage are easy to occur, so that the spindle is damaged due to the lack of lubricating action of the lubricating oil. The mode of oil supplement needs to stop, so that more labor is used, and the production efficiency and the spinning cost of the spinning frame are influenced.

Aiming at the technical problems, the invention discloses a centralized oil supply and lubrication system for spindles of a spinning frame, which has the advantages of more conveniently and quickly adding and supplementing lubricating oil, improving the production efficiency of the spinning frame, greatly reducing labor force, avoiding the phenomena of adding missing and adding less lubricating oil, prolonging the service life of the spindles and the like.
