The present invention realizes above-mentioned purpose like this: by overlapping yarn oil lubrication device at two-for-one twisting spindles built-in, reduced coefficient of friction by oiling when making yarn by this oil lubrication device, thereby reduce the yarn tension that yarn is produced in two-for-one twisting spindles, reduce the end breakage rate of yarn in the double twisting process.
The further setting of the present invention is:
Described oil seepage layer is wool felt or other oil absorption materials such as the oil absorbent material etc. that are adsorbed with lubricating oil.Like this, can be in adsorpting lubrication oil, overlubricate oil oozes out when preventing to produce.
Be provided with tank filler sleeve by top, can rationally control lubricants capacity at any time at shoe cream room.
Described yarn path comprises the yarn passing tube that is arranged at the oil seepage layer top, and is opened in the yarn-passing hole in the middle of the oil seepage layer, and the axial line of described yarn passing tube, yarn-passing hole is consistent with the yarn running orbit.Preferably, the diameter of yarn passing tube is greater than the diameter of yarn-passing hole; More preferably, yarn passing tube adopts ganoid material to make, as smooth porcelain spare, working of plastics.
The setting of yarn passing tube can make yarn have good running environment before entering oil seepage layer, because the existence of twisting in the tension pipe makes the yarn even running finish the coating of lubricating oil in the yarn-passing hole of oil seepage layer, effectively prevents the generation of broken yarn.
Preferably; The top of described oil seepage layer is inserted in the lower end of described yarn passing tube.Like this, can when containing more lubricating oil, shoe cream room ensure the running environment of yarn.
Another aspect of the present invention purpose provides the built-in yarn oil lubrication of a kind of two-for-one twisting spindles method, it is characterized in that, may further comprise the steps: yarn moves back to separate from the yarn tube and enters tension pipe, and enter oil seepage layer by yarn passing tube, because when twisting in yarn carries out in tension pipe, twisting air ring in can producing, during by oil seepage layer, the lubricating oil that oil seepage layer produces is stained with in yam surface; When yarn continues to be passed down through spindle blade porcelain spare and filament mouth porcelain spare, yarn slippage and mistake on spindle blade porcelain spare and filament mouth porcelain spare, produce friction, because the lubricating oil that speckles with on the yarn reduces coefficient of friction between them, reduced friction, the corresponding tension force that reduces yarn after yarn has gone out filament mouth porcelain spare, forms outer air ring outside in the twisting area, enter the coiling operation by guide porcelain spare again, finish the double twisting twisting process.
