Description

Technical Field

[0001] The invention relates to a component of a spinning frame, in particular to a driving mechanism of a spindle of the spinning frame. Background Art

[0002] like Figure 1 As shown, after being drawn, the fiber strands 100 of the existing spinning mechanism are twisted by the spindle tube 1 to form the yarn 200, and the spindle tube 1 rotates along with the spindle 14, and the spindle 14 is driven to rotate by the rotating mechanism.

[0003] like Figure 2 As shown, the rotating mechanism of the existing spindle tube 1 generally includes a main shaft 3, a roller 4, a spindle 14, a rib 6, and a spindle belt 5. The spindle tube 1 is sleeved on the spindle 14, the spindle 14 is installed on the rib 6, the spindle belt 5 is wrapped around the spindle 14, the spindle belt 5 is driven by the roller 4, the roller 4 is driven by the main shaft 3, the spindle belt 5 is provided with tension by the weight 15, the main shaft 3 inputs rotational power to drive the spindle belt 5, the spindle belt 5 drives the spindle 14 to rotate, and the spindle 14 drives the spindle tube 1 to rotate at high speed to make yarn. In order to increase yarn production, the existing spinning machine spindle 14 has an extremely high rotation speed, generally above 15,000 rpm. In order to achieve this rotation speed, the spindle belt 5 must be close to the surface of the spindle 14, which will give the high-speed running spindle 14 a lateral pressure, and the linear speed of the spindle belt 5 is also very high.

[0004] Figure 3 It is another rotating mechanism of the existing spindle 14, in which the spindle belt 16 is driven by the driving disk 18, and the spindle belt 16 is tensioned by the tensioning wheel 17, so that the spindle belt 16 generates a close force on the spindle 7, and the spindle 14 is driven to rotate through the spindle belt 16. This rotating mechanism also has a lateral force on the spindle, and in order to rotate the spindle 14 at a high speed, the linear speed of the spindle belt 16 is also very high.

[0005] When the above-mentioned spindle 14 rotates at high speed, in addition to bearing the axial gravity from the spindle itself and the yarn tube, it also has to bear the lateral force brought by the spindle belt transmission, which makes the spindle always deviate to one side, which is not conducive to the high-speed operation of the spindle. At the same time, the high linear speed of the spindle belt will generate a lot of noise, making the production environment relatively harsh. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a textile spindle assembly so as to eliminate the lateral force of the spindle.

[0007] The technical solution adopted by the present invention to solve the above technical problems is:

[0009] Better, the spindle is grounded, because the driven member and the driving member are both provided with magnets, when rotating, the magnetic force lines are cut, the spindle generates a certain current, and the spindle needs to be grounded and conductive.

[0010] Better, the fixing member is a fixing disc, a plurality of magnetic guide columns are evenly distributed along the circumference of the fixing disc, in this way, the fixing disc is easy to be installed on the dragon muscle, and because the fixing disc has a circular structure, the magnetic guide columns are easy to be installed uniformly.

[0011] Better, the driven member is a driven disc, the driven magnets are evenly distributed along the circumference of the driven disc, in this way, because the driven disc has a circular structure, the driven magnets are easy to be installed uniformly.

[0012] Better, the driving member is a driving disc, the driving magnets are evenly distributed along the circumference of the driving disc, in this way, because the driving disc has a circular structure, the driving magnets are easy to be installed uniformly.

[0013] Better, the lower part of the spindle is connected to the central through hole of the fixing disc through a bearing, so that the spindle can rotate with the lower part of the spindle as the center.

[0014] Better, the fixing disc is provided with fixing parts on the two sides, the fixing disc is fixed on the textile mechanism through the fixing parts, for example, the fixing disc is fixed on the dragon muscle of the spinning mechanism.

[0015] Better, the fixing disc is fixed on the textile mechanism through a T-shaped nut, the fixing disc is threadedly connected to the horizontal part of the T-shaped nut, the vertical part of the T-shaped nut is threadedly connected to a fixing nut, the fixing disc is fixed on the textile mechanism, for example, the fixing disc is fixed on the dragon muscle of the spinning mechanism, through the horizontal part of the T-shaped nut and the fixing nut.

[0016] More specifically, the fixed disc is evenly distributed with 8 magnetic guide columns along the circumference, through which the magnetic force lines of the magnets on the driving disc can pass and act on the driven magnets, so that the driving disc can better drive the spindle to rotate.

[0017] Better, the outer surface of the lower part of the sleeve of the fixed disc is provided with a bearing, which is connected with the driving disc sleeve through rolling, so that the driving disc sleeve can rotate around the sleeve as the center.

[0018] More specifically, the transmission part is a concave ring that can be embedded in the transmission belt, and the existing spindle belt of the rotating mechanism can be embedded in the concave ring and tightly attached to the outer wall of the driving disc sleeve, so that the driving disc sleeve is driven to rotate by the spindle belt, thereby rotating the driving disc.

[0019] Better, the number of driving magnets is 2-6 times that of driven magnets, so that the linear speed of the spindle belt can be greatly reduced at the same rotational speed of the spindle, thereby reducing noise.

[0020] Better, the fixed disc is provided with a downward first annular groove, and the driving disc is embedded in the first annular groove, so that dust or yarn in the environment is not easy to enter the driving disc, and it is easy to clean.

[0021] Better, the driven disc is provided with a downward second annular groove, and the fixed disc is embedded in the second annular groove, so that dust or yarn in the environment is not easy to enter the fixed disc, and it is easy to clean.

[0022] Compared with the prior art, the advantages of the present application are:

[0023] 1. Since the driving sleeve of the textile spindle assembly has no contact with the spindle, it does not bear the radial pressure from the outside during the rotation of the spindle, so the spindle is not subjected to lateral force, thereby improving the limit speed of the spindle and prolonging the life of the spindle.

[0024] 2. By adjusting the ratio of driving magnets to driven magnets, the ratio of external driving speed to spindle speed is adjusted, thereby reducing the input speed of the spindle. The number of driving magnets is greater than the number of driven magnets, so that the input speed of the spindle is lower than the actual working speed of the spindle, which can reduce the noise in the working environment and improve the working environment.

[0034] The present application will be further described in detail below with reference to the accompanying drawings. Embodiment 1

[0035] As shown in Figure 5 , Figure 6 , Figure 7 , the textile spindle assembly 8 comprises a driving disc assembly 81, a fixed disc assembly, and a spindle rod assembly 87.

[0036] The driving disc assembly 81 comprises a driving disc 811 and a driving disc sleeve 812, the upper end of the driving disc sleeve 812 is vertically fixed on the center of the driving disc 811.

[0037] The driving disc 811 is uniformly fixed with a plurality of driving magnetic particles 82 along the circumference, in this embodiment, there are 16 driving magnetic particles 82, the polarity of the driving magnetic particles 82 is opposite to that of the driven magnetic particles 89, so that they can attract each other.

[0038] The outer surface of the driving disc sleeve 812 is provided with a transmission part, in this embodiment, the transmission part is a concave ring 8121 capable of being embedded in the transmission belt, the spindle belt of the driving mechanism can be embedded in the concave ring 8121 and tightly adhere to the outer wall of the driving disc sleeve 812, the driving disc sleeve 812 is rotated by the spindle belt, so that the driving disc 811 is rotated.

[0039] The lower inner cavity of the driving disc sleeve 812 is provided with a bearing 84, the bearing 84 is sleeved outside the fixed disc sleeve 832.

[0040] The bottom end inner cavity of the driving disc sleeve 812 is also provided with a thrust bearing 841, which is limited by a fixed cap 843 and is threadedly connected to the inner cavity of the fixed disc sleeve 832 by a bolt 842, so that the driving disc sleeve 812 cannot move axially on the fixed disc sleeve.

[0041] The fixed disc assembly comprises a fixed disc 831 and a sleeve 832, which is vertically fixed at the center of the fixed disc 831.

[0042] The fixed disc 831 is provided with a through hole 8311 at the center, which communicates with the inner cavity of the sleeve 832, and together forms an internal passage that can accommodate the lower part 871 of the spindle.

[0043] In this embodiment, the central through hole 8311 of the fixed disc 831 is provided with a bearing 86, and of course, the inner cavity of the sleeve 832 can also be provided with a bearing, which is in rolling connection with the lower part 871 of the spindle through the bearing 86, so that the spindle 87 can rotate around the lower part 871 of the spindle, that is, rotate coaxially around the fixed disc 831.

[0044] The fixed disc 831 is also provided with a fixed part 8311 on the two sides, and the fixed part 8311 is provided with a fixed hole 8312, and the fixed disc 831 is fixed on the spindle 6 of the spinning mechanism or other parts of the spinning mechanism by the screw 19 through the fixed hole 8312.

[0045] The fixed disc 831 is evenly distributed with several magnetic guide columns 85 along the circumference, and eight magnetic guide columns 85 are used in this embodiment. Through these magnetic guide columns 85, the magnetic lines of the driving magnetic particles 82 on the driving disc below can pass through and act on the driven magnetic particles 89 on the spindle below, so that the driving disc 81 drives the spindle 87 to rotate.

[0046] The lower outer surface of the sleeve 832 of the fixed disc 831 is provided with a bearing 84, the upper end of which is limited by the upper step 8321 on the sleeve 832, and the lower end of which is limited by the lower step 8322 on the sleeve 832. In this way, the driving disc sleeve 812 is in rolling connection with the sleeve 812 through the bearing 84, so that the driving disc sleeve 812 can rotate around the sleeve 832 as the axis.

[0047] The spindle assembly comprises a spindle 87 and a driven disc 88, and the spindle 87 passes through the driven disc 88 and is fixedly connected with the spindle 87.

[0048] The lower part of the spindle 87 is inserted into the bearing 86, and the driven disc 88 is axially limited by the fixed disc 831, and in this embodiment, the driven disc 88 is supported by the fixed disc 831.

[0049] The driven disc 88 is evenly provided with a plurality of driven magnetic particles 89 along the circumference, and four driven magnetic particles 89 are used in this embodiment.

[0050] The number of the driven magnetic particles 89 is related to the number of the magnetic particles 82 on the driving disk, and the ratio of the linear speed of the driving disk assembly 81 to the linear speed of the driven disk 88 is adjusted by adjusting the ratio of the number of the driven magnetic particles 89 to the number of the driving magnetic particles 82.

[0051] The number of the magnetic particles 82 on the driving disk 81 in this embodiment is four times the number of the driven magnetic particles 89 on the driven disk 88, so when the driving disk 81 rotates one round, the driven disk 88 can rotate four rounds, and correspondingly, the spindle 87 fixed with the driven disk 88 can also rotate four rounds, thus the linear speed of the spool 9 can be greatly reduced at the same rotational speed of the spindle 87, so that the noise can be reduced.

[0052] Since the lower part 871 of the spindle 87 is placed in the bearing 86, it no longer bears the lateral force of the driving mechanism spool when it is driven, and the spindle 87 no longer deviates. Moreover, the spindle assembly is basically the same as the existing spindle structure, only that the driven magnetic particles 89 are installed on the driven disk, so it is convenient to modify the existing textile equipment.

[0053] The fixed disk 831 is provided with a downward first annular groove 8313, and the driving disk 811 is embedded in the first annular groove 8313, so that dust or yarn in the environment is not easy to enter the driving disk, and it is easy to clean.

[0054] The driven disk 88 is provided with a downward second annular groove 881, and the fixed disk 831 is embedded in the second annular groove 881, so that dust or yarn in the environment is not easy to enter the fixed disk, and it is easy to clean. Embodiment 2

[0055] As shown in Figure 8 , Figure 9 , it is another structure of the textile spindle assembly 7, which is only different from the embodiment 1 in the following contents.

[0056] In this embodiment, the connection mode of the fixed disk 72 and the beam 6 or other textile mechanism is changed, and the fixed disk 72 is fixed on the beam 6 through the spindle holder 74.

[0057] The spindle holder 74 is a T-shaped nut, and the horizontal part is a nut with an internal thread 741, and correspondingly, the fixed disk 72 has an external thread 721 on the outer circle, and the fixed disk 72 is fixed on the internal thread 741 of the spindle holder 74 through the internal thread.

[0058] The outer circle of the vertical part of the spindle holder 74 is provided with an external thread 742, so that when the spindle holder 74 is fixed on the beam 6, it can be inserted into the fixing hole (not shown in the figure) of the beam 6 and then fixed on the beam 6 by tightening the nut 73 on the external thread of the spindle holder 74.

[0059] In addition to the fixing mode of the fixed disc of the present embodiment and embodiment 1 fixed to the dragon muscle 6 or other textile mechanism, the fixed disc can be fixed to the dragon muscle 6 by other commonly used fixing modes of two objects, which are not listed one by one here.

[0060] The structure of the driving disc assembly of the present embodiment is completely the same as that of embodiment 1 except that the number of driving magnetic particles uniformly distributed along the circumference of the driving disc and the threads arranged on the outer circumferential surface of the driving disc. The driving disc 77 of the present embodiment has 12 driving magnetic particles 82 uniformly distributed along its circumference.

[0061] The spindle assembly of the present embodiment has 4 driven magnetic particles 89 installed on the driven disc, and the rest is completely the same as that of embodiment 1. The lower part of the spindle is inserted into the inside of the bearing, and the spindle can rotate coaxially around the fixed disc.

[0062] Therefore, the number of magnetic particles 82 on the driving disc 77 of the present embodiment is 3 times that of the driven magnetic particles 89 on the driven disc 78. Therefore, when the driving disc rotates 1 turn, the driven disc rotates 3 turns, and the spindle 75 also rotates 3 turns. Therefore, under the same rotational speed of the spindle 75, the linear speed of the spool 9 is greatly reduced, and thus the noise can be reduced. At the same time, the spindle 75 no longer bears the lateral force of the spool 9, and the spindle 75 will not be biased to one side of the bearing.

[0063] In the above embodiments, the driving disc assembly 81, the fixed disc assembly, and the spindle assembly 87 are described in the form of an assembly, and are described separately by parts, for example, the fixed disc assembly includes a fixed disc and a fixed sleeve, which are manufactured and connected together respectively. Of course, the fixed disc assembly can also be described directly by the name of the fixed disc, and the fixed disc and the fixed sleeve are integrally manufactured as constituent parts.

[0064] As shown in Figure 4 The rotation mechanism of the above textile spindle assembly adopts the rotation mechanism of the existing spindle, and only the existing spindle is replaced by the spinning spindle assembly. The rotation mechanism includes the main shaft 3, the steering pinion 10, the steering gear 11, the flyer 12, the spool 9, and the dragon muscle 6. The steering pinion 10 and the steering gear 11 are perpendicular to each other. The steering gear 11 drives the flyer 12 through the transmission belt (not shown in the figure). Each flyer 12 is driven through the spool 9, the tensioning wheel 13, and the tensioning wheel 19 between the flyer 12. The textile spindle assembly is fixed to the dragon muscle 6.

[0065] When the spindle rotation mechanism operates, the external driving force drives the main shaft 3 to rotate the steering pinion 10, which in turn drives the steering gear 11 after reversing. The steering gear 11 drives the flyer 12, which in turn drives the spool 9. The spool 9 is tightly attached to the driving sleeve of the spindle assembly after being tensioned by the tensioning wheel 13 and the tensioning wheel 19. The spool 9 drives the driving sleeve of the spindle assembly to rotate.
