Description

Technical Field

[0001] The present invention relates to the technical field of doubling equipment, and more specifically, to a lubricating device for chemical fiber doubling spindles and silk threads. Background Art

[0002] In order to reduce the damage to the yarn during doubling, a small amount of oil is applied to the surface of the yarn before doubling, which is commonly used in yarn doubling. The patent number CN109487381A discloses an internal yarn oil lubrication method and device for a lubricating device for chemical fiber doubling spindles and silk threads. This patent proposes that when the yarn passes through the oil-seeping yarn channel during twisting, the yarn contacts the inner wall of the oil-seeping yarn channel, and the oil liquid seeping out through the oil-seeping yarn channel contacts the yarn to achieve oiling and lubrication of the yarn. There are deficiencies in this method: First, the oil-seeping yarn channel is relatively long, and the contact range between the yarn and the oil-seeping yarn channel is excessive. During the contact process between the yarn and the oil-seeping yarn channel, the yarn will be damaged to a certain extent, which will also increase the risk of yarn breakage; Second, when the spindle is not in use, the oil-seeping yarn channel will continuously seep oil slowly, resulting in the loss of lubricating oil in the oil storage cavity and frequent oiling operations, increasing the workload. Therefore, it is urgent to improve this. Summary of the Invention

[0015] 1. Through the capillary principle, the capillary belt can attract the lubricating oil in the oil storage cavity to the upper end of the capillary belt. When the yarn passes through the through-hole, the yarn contacts the capillary belt, so that the oil on the capillary belt contacts the surface of the yarn, realizing oiling and lubricating of the yarn. And because the capillary belt is made of polyester fiber yarn and has a small contact range with the yarn, it can reduce the damage of the yarn while oiling the yarn, thereby reducing the risk of yarn breakage.

[0016] 2. When the first porcelain bowl moves downward, the lower part of the first porcelain bowl can first abut against the upper surface of the capillary belt. When the first porcelain bowl continues to move downward, it can push the part of the capillary belt higher than the oil outlet to move downward, so that the lower part of the capillary belt abuts against the upper part of the support seat. When the first porcelain bowl continues to move downward, the support seat deforms, and the first porcelain bowl and the support seat jointly squeeze the capillary belt. At this time, it is equivalent to blocking the capillary channel of the capillary belt, and the lubricating oil cannot be transported to the area of the capillary belt at the through-hole. Through this design, when the spindle is not in use, the area of the capillary belt at the through-hole will not continuously seep oil, thereby effectively reducing the loss of lubricating oil in the oil storage cavity.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 6 shown, this embodiment discloses a lubricating device for chemical fiber doubling spindles and silk threads, including a spindle sleeve 1. A sleeve 9 is fixedly connected inside the spindle sleeve 1. A lubrication mechanism 2000 and a twisting unit 8 are arranged inside the sleeve 9. The twisting unit 8 is located below the lubrication mechanism 2000. Support ribs 12 are arranged inside the spindle sleeve 1. The number of the twisting units 8 is multiple. In this embodiment, it is preferably two. The upper part of the twisting unit 8 located at the uppermost part abuts against the lower part of the lubrication mechanism 2000, and the lower part of the twisting unit 8 located at the lowermost part abuts against the upper part of the support rib 12. The twisting unit 8 includes a second porcelain bowl 81, and a tension ball 82 is arranged inside the second porcelain bowl 81. A gasket ring 11 is threadedly connected to the upper part of the spindle sleeve 1, and a yarn bobbin 300 is sleeved outside the spindle sleeve 1;

[0026] As Figure 1As shown in the figure, during operation, the yarn bobbin 300 is installed on the bobbin base 100. The yarn 200 is unwound from the yarn bobbin 300, passes through the cushioning loop 11, then is inserted into the spindle sleeve 1 from the upper end of the cushioning loop 11, and successively passes through the lubrication mechanism 2000 and the twisting unit 8. When the yarn 200 passes through the twisting unit 8, it is twisted at the contact point between the second porcelain bowl 81 and the tension ball 82, and then extends out from the wire outlet 400. After the yarn 200 passes through the wire outlet 400, an outer air ring is formed in the external twisting area, and then it enters the winding process through the yarn guiding porcelain part 500 to complete the double twisting process. Moreover, after the yarn 200 passes through the lubrication mechanism 2000, the surface of the yarn 200 can be oiled, reducing the number of yarn breakages of the yarn 200.

[0027] As Figure 2 and Figure 3 shown, the lubrication mechanism 2000 includes an oil storage part 2. The upper part of the twisting unit 8 located at the uppermost part abuts against the lower part of the oil storage part 2. The oil storage part 2 includes an oil storage cavity 22 and a yarn passing channel 21. The oil storage cavity 22 is located outside the yarn passing channel 21, and lubricating oil is stored in the oil storage cavity 22. A porcelain ring 23 is embedded at the upper end of the yarn passing channel 21. The inner diameter of the porcelain ring 23 is smaller than the cross-sectional dimension of the yarn passing channel 21. The yarn passing channel 21 is located directly above the twisting unit 8. An oiling component 1000 is provided at the upper part of the oil storage cavity 22. The yarn 200 passes through the oiling component 1000, the porcelain ring 23, the yarn passing channel 21 and the twisting unit 8 from top to bottom. By setting the porcelain ring 23, the yarn 200 can be guided and limited, preventing the yarn 200 from contacting the yarn passing channel 21 during twisting and preventing the yarn passing channel 21 from damaging the yarn 200.

[0028] As Figures 3 to 5 shown, the oiling component 1000 includes a cover body 3 and a capillary band 7. The cover body 3 is a rubber part. The cover body 3 includes a support seat 32. The support seat 32 covers the upper part of the oil storage cavity 22. The upper end of the oil storage part 2 is inserted into the inside of the support seat 32 and fixed. The support seat 32 includes an oil outlet 34 and a through hole 37. The through hole 37 is located directly above the porcelain ring 23. The inner diameter of the porcelain ring 23 is smaller than that of the through hole 37. The oil outlet 34 is of a flat structure. One end of the capillary band 7 is located in the oil storage cavity 22 and immersed in the lubricating oil. The other end of the capillary band 7 passes through the oil outlet 34 and is located at the through hole 37. The capillary band 7 is a fiber band. The fiber band is formed by arranging polyester fiber yarns side by side. Since the lubricating oil is an oily material, the capillary band 7 is made of polyester fiber with a hydrophobic material, which can improve the wettability;

[0029] The capillary zone 7 can attract the lubricating oil in the oil storage cavity 22 to the upper end of the capillary zone 7 through the capillary principle. When the yarn 200 passes through the through hole 37, the yarn 200 contacts the capillary zone 7, so that the oil on the capillary zone 7 contacts the surface of the yarn 200, realizing oiling and lubricating of the yarn. And because the capillary zone 7 is made of polyester fiber yarn and has a small contact range with the yarn 200, it can reduce the damage of the yarn 200 while oiling the yarn 200, thereby reducing the risk of breakage of the yarn 200.

[0030] As Figure 4 shown, a first porcelain bowl 4 is provided above the support seat 32. The first porcelain bowl 4 includes a yarn passing opening 41. The yarn passing opening 41, the through hole 37 and the yarn passing channel 21 are coaxially arranged. The size of the through hole 37 is larger than the opening at the lower end of the yarn passing opening 41 and smaller than the yarn passing channel 21. The yarn 200 can be effectively prevented from contacting the inner wall of the through hole 37 during the twisting process through the guiding and limiting of the yarn passing opening 41 and the porcelain ring 23, thereby reducing the risk of breakage of the yarn 200.

[0031] The first porcelain bowl 4 includes an oil inlet hole 42 which is vertically arranged. An installation groove 43 communicated with the oil inlet hole 42 is provided at the lower part of the oil inlet hole 42. An oil injection joint 36 is provided at the upper part of the support seat 32. The upper end of the oil injection joint 36 is inserted into the installation groove 43. There is an activity space between the upper end of the oil injection joint 36 and the upper end of the installation groove 43. An oil injection port 361 is provided in the oil injection joint 36. The oil inlet hole 42 is communicated with the oil storage cavity 22 through the oil injection port 361. The oil injection port 361 is a notch. It can be seen that the oil injection operation for the oil storage cavity 22 can be realized through a syringe (not shown in the figure). Specifically, when it is necessary to inject oil into the oil storage cavity 22, the gasket ring 11 is unscrewed. The needle of the syringe sequentially penetrates through the oil inlet hole 42, the oil injection joint 36 and the oil injection port 361 and is inserted into the oil storage cavity 22, and the oil injection operation can be realized. The operation is convenient and efficient. And because the cover body 3 is made of rubber material, after the oil injection is completed, the oil injection port 361 can be automatically closed, thereby preventing the oil in the oil storage cavity 22 from leaking out from the oil injection joint 36, and the sealing reliability is good.

[0032] The part of the capillary zone 7 above the oil outlet 34 is located between the support base 32 and the first porcelain bowl 4. The first porcelain bowl 4 is movably connected to the sleeve 9. The cover 3 further includes a connecting sleeve 31 located above the support base 32. The connecting sleeve 31 is movably connected to the inner wall of the sleeve 9. A bushing 5 is fixedly connected to the outside of the connecting sleeve 31. The upper part of the first porcelain bowl 4 is provided with a first annular platform 46. The lower part of the first annular platform 46 abuts against the upper part of the bushing 5. The side wall of the bushing 5 is in clearance fit with the inner wall of the sleeve 9. The bushing 5, the connecting sleeve 31 and the first porcelain bowl 4 can move up and down synchronously, so that the lower part of the first porcelain bowl 4 can abut against the upper part of the support base 32 and squeeze the part of the capillary zone 7 above the oil outlet 34. Specifically, the bushing 5 is a metal part, and the bushing 5 and the cover 3 are made by the way of two-shot injection molding. Since the connecting sleeve 31 is made of rubber material, by setting the bushing 5, not only the fixing effect of the first porcelain bowl 4 can be improved, but also the fit between the bushing 5 and the inner wall of the sleeve 9 can be effectively improved, making the up and down movement of the bushing 5 smoother;

[0033] When the first porcelain bowl 4 moves downward, the lower part of the first porcelain bowl 4 can first abut against the upper surface of the capillary zone 7. When the first porcelain bowl 4 continues to move downward, it can push the part of the capillary zone 7 above the oil outlet 34 to move downward, so that the lower part of the capillary zone 7 abuts against the upper part of the support base 32. When the first porcelain bowl 4 continues to move downward, the support base 32 deforms, and the first porcelain bowl 4 and the support base 32 jointly squeeze the capillary zone 7. At this time, it is equivalent to blocking the capillary channel of the capillary zone 7, and the lubricating oil cannot be transported to the area of the capillary zone 7 at the through hole 37. Through this design, when the spindle is not in use, the area of the capillary zone 7 at the through hole 37 will not continuously leak oil, so that the loss of the lubricating oil in the oil storage cavity 22 can be effectively reduced.

[0034] Specifically, the upper part of the support base 32 is provided with an annular groove 38, the annular groove 38 is located on the outer periphery of the through hole 37, the lower part of the first porcelain bowl 4 is provided with a boss 44, the lower part of the boss 44 can abut against the upper part of the support base 32, and the lower part of the boss 44 is provided with an annular rib 45. The annular rib 45 can be inserted into the annular groove 38. Through the cooperation of the annular rib 45 and the annular groove 38, the blocking effect of the capillary channel of the capillary zone 7 can be effectively improved.

[0035] The connecting sleeve 31 and the support base 32 are connected by a connecting ring 33. The connecting ring 33 is a flexible member. The connecting sleeve 31, the support base 32 and the connecting ring 33 are integrally formed. The connecting sleeve 31 is sleeved outside the first porcelain bowl 4 and fixedly connected to the first porcelain bowl 4. The cross-section of the connecting ring 33 is an arc structure with a thin wall and is easy to deform. When the first porcelain bowl 4 descends, the connecting ring 33 can deform. And an avoidance cavity 35 is formed among the first porcelain bowl 4, the support base 32 and the connecting ring 33. The part of the capillary band 7 higher than the oil outlet 34 is located in the avoidance cavity 35. The oil injection joint 36 is located in the avoidance cavity 35. The avoidance cavity 35 is isolated from the inner wall of the sleeve 9. By adopting this method, it can effectively prevent the lubricating oil from seeping out from the peripheral side of the cover body 3 to the inner wall of the sleeve 9. Moreover, the arc of the cross-section of the connecting ring 33 protrudes towards the avoidance cavity 35. When the first porcelain bowl 4 descends, the connecting ring 33 can deform towards the avoidance cavity 35. The support base 32 is subjected to the extrusion of the first porcelain bowl 4 and the deformation of the connecting ring 33, so as to be able to close the upper end of the oil outlet 34 and avoid the leakage of the lubricating oil during the transportation of the spindle.

[0036] Specifically, a plurality of reinforcing ribs 39 are arranged on the outer wall of the connecting ring 33 and are evenly distributed along its axis. The reinforcing ribs 39 are respectively connected to the connecting sleeve 31 and the support base 32. By arranging the reinforcing ribs 39, it is beneficial to improve the reset effect of the connecting sleeve 31.

[0037] As Figure 3 shown, a limiting component 6 is connected to the upper end of the sleeve 9. The lower part of the limiting component 6 abuts against the upper part of the oiling component 1000. The limiting component 6 can push the first porcelain bowl 4 to move downward. The limiting component 6 includes an adapter sleeve 61, a lifting sleeve 62 and a flat gasket 63. The adapter sleeve 61 is fixedly connected to the inner wall of the sleeve 9. The lifting sleeve 62 is inserted into the adapter sleeve 61 and is threadedly connected to the adapter sleeve 61. The upper part of the flat gasket 63 abuts against the lower part of the lifting sleeve 62 and the lower part abuts against the upper part of the first porcelain bowl 4. A second annular platform 621 is arranged on the upper part of the lifting sleeve 62. The outer cross-section of the second annular platform 621 is hexagonal. By rotating the lifting sleeve 62, the first porcelain bowl 4 can be pushed to descend, so as to realize the blocking of the capillary channel. When the lifting sleeve 62 moves upward, the connecting ring 33 and the reinforcing ribs 39 recover, thereby driving the first porcelain bowl 4 to rise and the capillary channel to communicate. The flat gasket 63 is made of rubber. By arranging the flat gasket 63, it can play a protective role for the first porcelain bowl 4 and avoid the direct contact between the lifting sleeve 62 and the first porcelain bowl 4.

[0038] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
