Description

Technical Field

[0001] The utility model relates to textile machinery and spinning processing technology, in particular to a cantilever multi-fold twisting spinning device. Background Art

[0002] The traditional twisting technology is one twist per spindle rotation, and the production and twisting efficiency of this twisting technology is low. Therefore, doubling the twisting efficiency through the technology of multiple twists per spindle rotation has become the goal of achieving high-efficiency production in the textile industry.

[0003] The double-twisting technology is a well-developed twisting technology that realizes two twists per spindle rotation, breaking through the limitation of the traditional one-twist-per-spindle-rotation technology. The twisting efficiency is increased several times compared with traditional twisting equipment, and it is warmly welcomed by the market. Chinese textile enterprises began to import double-twisting machines in the early 1980s of the last century, and realized that double-twisting machines have great advantages of high production efficiency and good product quality, and the market demand is strong. After more than forty years of development, China has made great progress in the production technology of double-twisting machines. The double-twisting machines are diverse in variety and excellent in quality, and occupy an important position in the world textile machinery market.

[0004] The patent "Planetary Gear Composite Twister (201410331775.7)" proposed a planetary gear composite twister. However, the patent did not disclose the specific process of single fiber yarn merging, twisting, and plying into a rope. Through the study of this invention patent, the specific process of this patent is preliminarily interpreted as Figure 7 shown. Since the feeding end and the output end are in a continuous state and no free end is formed, for the yarn with both ends continuous, only false twist can be formed during the rotational twisting in the middle part, not true twist; for this patent, multiple yarns will be twisted on both sides of the planetary gear composite twister as the planetary gear composite twister rotates. On the one hand, the twist degrees on both sides of the planetary gear composite twister are the same and the twist directions are opposite, which is false twist; on the other hand, when the feeding end side of the planetary gear composite twister is twisted, the yarns are twisted together and cannot be threaded into the wire holes of the planetary gears one by one, that is, the invention device simply cannot produce and process. Therefore, the patent scheme is infeasible in terms of the spinning principle.

[0005] The patent "Twisting and covering mechanism for producing twisted covered yarns (201920200182.5)" proposes a twisting and covering mechanism for producing twisted covered yarns. The spinning principle of this patent is as follows: The outer covering yarn passes through the hollow shaft of the motor and the rotating guide screw rod, and converges with the core yarn at the position of the wire guide ring (holding point). The core yarn is fixed on the positioning bracket, and the positioning magnet on the bracket prevents it from rotating with the output shaft. The generator or wireless power transmission module drives and controls the active yarn feeding roller to feed yarn at a set speed. The core yarn and the outer covering yarn are combined at the wire guide ring, and the outer covering yarn rotates around the core yarn. For each rotation, a covering twist is formed on the core yarn, and at the same time, a self-twist is generated at the lower part of the rotating guide screw rod. The direction of the self-twist is opposite to the direction of the covering. Its effect is equivalent to the outer covering yarn rotating clockwise (or counterclockwise) while revolving around the core yarn counterclockwise (or clockwise). After the self-twist and covering, the twisted covered yarn is sent to the external winding mechanism through the driving roller and the driven roller. In this patent, a complex mechanism with two transmission units is adopted. One is the outer covering yarn, which drives the guide screw rod through an independent motor. The rotation of the guide screw rod completes the self-twist of the outer covering yarn and the covering of the core yarn. The two twist degrees are the same but in opposite directions, and the process has great limitations. The other is the core yarn, which is driven by an independent motor to evenly output the core yarn. The core yarn is covered by the outer covering yarn, and the core yarn itself does not rotate or twist. At the same time, in this patent, the outer covering yarns are twisted into one yarn, and only one yarn is used to limit the covering of the core yarn.

[0006] Therefore, how to efficiently complete the processing of ropes and cables with different structures and diversities in a short process is an urgent problem to be solved. Summary of the Utility Model

[0011] Preferably, the yarn storage barrel is relatively fixed to the hollow spindle through a magnetic ring, preventing the yarn storage barrel from rotating with the double-twist spindle, so as to ensure that the twisting mechanism realizes one-turn double twisting.

[0012] Preferably, a number of covered tube yarns are arranged in the yarn storage barrel, and a corresponding number of yarn guide tubes and / or first yarn guide hooks are arranged on the double-twist spindle center tube.

[0017] Beneficial effects: Compared with the prior art, the utility model has the following remarkable advantages: 1. By adopting technologies such as multi-yarn doubling and twisting, multi-strand doubling and twisting, and core-spun in a set of devices, the production of ropes and cables is completed at one time, realizing the integration of multiple functions such as yarn doubling, double twisting, and core-spun. Compared with the traditional spinning process, it has the functions of three different devices in three processes, namely a yarn doubling machine, a double twister, and a core-spun covering machine. Only one device can complete the processing of up to dozens of yarns into composite structure ropes and cables, which can effectively shorten the spinning process, reduce labor, save energy, and improve the modernization level of the textile industry through high-efficiency short-process production technology; 2. Adopting the two-stage twisting technology, the first stage of twisting is the self-rotation of the double twister spindle, which completes the twisting of several covered yarns in the yarn storage barrel. The double twister spindle rotates and twists twice. The second stage of twisting is the revolution of the double twister spindle, which completes the covering and twisting of the covering yarn around the core yarn, one revolution and one twist. Through the design of the transmission ratio between the cantilever and the double twister spindle, the high-efficiency twisting effect of multiple twists per revolution of the main shaft can be achieved through two-stage twisting; 3. Multiple yarns with different properties can be used, and three different covered yarns with different yarn threading methods can be formed to realize the processing of multiple composite structure ropes and cables at one time, with strong production adaptability; 4. Since a large centrifugal force is generated on the yarn storage barrel of the double twister spindle during the revolution of the double twister spindle arranged on the turnover wheel, which affects the stability of the equipment and the wear of the structure. By setting an external gear ring meshing with the turnover wheel, the external gear ring can provide support to avoid the double twister spindle from bearing a large shear stress at the cantilever, which can further improve the rotation stability of the double twister spindle and reduce the wear of the equipment.

In the present utility model, only 3, 4, and 5 groups of turnover wheels Z1 and double-twist mechanisms are designed, asFigure 2 As shown, it is not actually limited to these three designs only.

[0035] The working principle of the cantilever type multi-fold twisting spinning device is as follows: The motor M1 drives the hollow spindle 23 to rotate, and the cantilever H mounted on the hollow spindle 23 rotates accordingly. The epicyclic gear Z1 mounted on the cantilever H meshes with the external gear ring Z2 fixed on the frame. The epicyclic gear Z1 forms self-rotation and revolution as the cantilever H rotates; the doubling spindle 28 is mounted on the epicyclic gear Z1 and rotates together with the epicyclic gear Z1.

[0040] Embodiment 4

[0041] A cantilevered multi-doubling spinning method according to the present utility model includes the following steps:

[0042] (a) The core yarn A of the core yarn feeding mechanism 1 is led out by the rotation of the unwinding roller 12 and enters the hollow spindle 23 through the yarn guide roller 13;

[0043] (b) The motor M1 of the cantilevered multi-doubling mechanism 2 drives the hollow spindle 23 through the motor pulley D1 and the hollow spindle main shaft pulley D2. The hollow spindle 23 drives the cantilever H to rotate together. The planet wheel Z1 provided on the cantilever H forms both a revolution around the hollow spindle 23 and a rotation around the center of the planet wheel Z1 in the transmission train; so that multiple covering yarns B in the covering yarn twisting mechanism are combined and twisted at the second yarn guide hook 25 to form the covered yarn C;

[0044] (c) Several covered yarns C enter the central hollow tube of the hollow spindle 23 through the yarn guide holes 24 provided on the side of the hollow spindle 23 and converge with the core yarn A. With the revolution of the planet wheel Z1, the covering and twisting of the core yarn A are completed to form the rope D;

[0045] (d) In the rope winding mechanism 3, the rope passing through the hollow spindle 23 passes through the rope guide roller 32, and the winding of the rope D is completed under the rotation of the winding roller 31.

[0046] The combination and twisting of multiple covering yarns B in the covering yarn twisting mechanism to form the covered yarn C include the following three methods:

[0047] (i) The yarn guide tubes 26 with the same number as the covered cheeses 21 are provided on the doubling spindle central tube 22. The covering yarns of all the covered cheeses 21 in the cheese storage barrel 20 are led out to the second yarn guide hook 25 through the yarn guide tubes 26, the doubling spindle central tube 22, and the doubling spindle 28, and are twisted at the second yarn guide hook 25 to form the first covered yarn C1;

[0048] (ii) Replace all the yarn guide tubes 26 in the yarn storage barrel 20 with the first yarn guide hooks 29. The covering yarns of all the covered cheese 21 in the yarn storage barrel 20 are directly led out to the second yarn guide hook 25 through the first yarn guide hooks 29, and a second covering line C2 is formed at the second yarn guide hook 25. The second covering line C2 is a combined yarn of multiple covering yarns B and has no twist.

[0049] (iii) Replace some of the yarn guide tubes 26 in the yarn storage barrel 20 with the first yarn guide hooks 29. The covering yarns of some of the covered cheese 21 in the yarn storage barrel 20 are directly led out to the second yarn guide hook 25 through the first yarn guide hooks 29 as the core yarns, and the covering yarns of some of the covered cheese 21 are led out to the second yarn guide hook 25 through the yarn guide tubes 26, the center tube 22 of the doubling spindle, and the doubling spindle 28 as the covering yarns. Twisting is performed at the second yarn guide hook 25 to form a third covering line C3. The third covering line C3 has a core - sheath structure.

[0050] Twisting and covering of the core yarn A are completed in the hollow spindle 23 to form several covering lines C of the cable D, which are one or more combinations of the first covering line C1, the second covering line C2, and the third covering line C3. Cables D with various structures can be formed to meet the requirements of different application scenarios.

[0051] In the present utility model, the working process of the cantilever - type multi - doubling mechanism 2 is divided into two steps. The first step is that the turnover wheel Z1 rotates self - rotatably to complete the doubling and twisting of multiple covering yarns B in the twisting mechanism to form the covering line C. The second step is that the turnover wheel Z1 rotates revolutionarily to complete the twisting and covering of multiple covering lines C on the core yarn A to form the cable D. Moreover, the self - rotation direction of the turnover wheel Z1 in the first step is opposite to the revolution direction of the turnover wheel Z1 in the second step, and the twist direction of the covering line C is opposite to that of the cable D. The cable D produced has a stable structure and good flexibility. The twist calculation during the two - step working process in the present utility model is as follows:

[0052] In case (i), assume the speed of the motor M1 is n (r / min), and the speed of the cantilever H is n H The calculation formula is:

[0053]

[0054] Among them, d1 represents the diameter of the motor pulley (mm), and d2 represents the diameter of the belt pulley on the main shaft of the hollow spindle (mm).

[0055] Since the external gear ring Z2 is fixed, the turnover wheel Z1 is driven by the cantilever H, and the self - rotation direction of the turnover wheel Z1 is opposite to the rotation direction of the cantilever H, as shown in Figure 3 So the self - rotation speed of the turnover wheel Z1 is the product of the transmission ratio between the turnover wheel Z1 and the external gear ring Z2 and the speed of the cantilever H. The self - rotation speed n Z1 of the turnover wheel Z1 is:

[0056]

[0057] Among them, is the transmission ratio between the epicyclic gear Z1 and the external gear ring Z2.

[0058] Since the epicyclic gear Z1 adopts a doubling twisting mechanism, one revolution and two twists. Assuming that during the production and processing of the wire rope, the speed of the winding roller 31 is v (m / min), the calculation formula for the twist T1 (twists / m) of the covering yarn C is:

[0059]

[0060] The calculation formula for the covering twist T2 (twists / m) of multiple covering yarns C on the core yarn A is:

[0061]

[0062] The calculation formula for the twist ratio η between the covering yarn C and the wire rope D is:

[0063]

[0064] In case (ii), the covering yarn enters the first yarn guide hook 29, directly enters the second yarn guide hook 25 without passing through the doubling twisting spindle 28, and the formed covering yarn C3 has no twist, belonging to non-twisted.

[0065] In case (iii), as Figure 6 shown, the covering bobbin yarn 21 in the yarn storage barrel 20 is divided into two parts B1 and B2; among them, B2 is used as the core yarn, non-twisted, and B1 is used as the covering yarn, twisted; the covering yarns B1 and B2 are twisted and covered at the second yarn guide hook 25 to form a core-spun structure covering yarn C3.

[0066] Specifically, the covering yarn B2 in part of the covering bobbin yarn 21 passes through the first yarn guide hook 29 and is directly led out to the second yarn guide hook 25 without passing through the doubling twisting spindle 28. This part of the covering yarn B2 is used as the core yarn and has no twist, belonging to non-twisted; the covering yarn B1 of part of the covering bobbin yarn 21 enters the second yarn guide hook 25 through the yarn guide tube 26 and the doubling twisting spindle 28. This part of the covering yarn B1 is first twisted to form a ply yarn at the center tube 22 of the doubling twisting spindle. The covering yarn B1 is led out from the lateral side holes of the doubling twisting spindle disk and enters the second yarn guide hook; the two covering yarns B1 and B2 converge at the second yarn guide hook 25. The covering yarn B1 rotates with the doubling twisting spindle 28, and the covering yarn B2 does not rotate, forming the covering of the covering yarn B1 on the covering yarn B2, which is called the first covering, and the core-spun structure covering yarn C3 is completed.

[0067] The covered yarn B1 undergoes two - stage twisting. The first - stage twisting is that the covered yarn B1 itself twists to form a ply yarn along with the rotation of the double - twister spindle 28. The second - stage twisting is that the covered yarn B1 twists to cover the covered yarn B2 along with the rotation of the double - twister spindle 28 to form a core - spun structure. The twist levels and directions of the two - stage twistings are the same.

[0068] Let the speed of the motor M1 be n (r / min), and the speed of the cantilever H be n H The calculation formula is:

[0069]

[0070] where d1 represents the diameter of the motor pulley (mm), and d2 represents the diameter of the hollow spindle main - shaft pulley (mm).

[0071] Since the external gear ring Z2 is fixed, the epicyclic gear Z1 is driven by the cantilever H, and the self - rotation direction of the epicyclic gear Z1 is opposite to the rotation direction of the cantilever H, as shown in Figure 3 So the self - rotation speed of the epicyclic gear Z1 is the product of the transmission ratio between the epicyclic gear Z1 and the external gear ring Z2 and the speed of the cantilever H. The self - rotation speed n of the epicyclic gear Z1 Z1 is:

[0072]

[0073] where is the transmission ratio between the epicyclic gear Z1 and the external gear ring Z2.

[0074] The covered yarn B1 passes through the double - twister mechanism. After the first - stage twisting is completed at the center tube of the double - twister mechanism, it then undergoes the second - stage covering twist with the covered yarn B2 to form the covered yarn C3.

[0075] The twist T of the first - stage twisting of the covered yarn B1 11 (turns / m), and the calculation formula is:

[0076]

[0077] The twist T of the second - stage covering twist of the covered yarn B1 12 (turns / m), and the calculation formula is:

[0078]

[0079] The calculation formula for the covering twist T2 (turns / m) of multiple covered yarns C on the core yarn A is:

[0080]

[0081] Considering that the structure of the covered yarn C3 is relatively complex, with both the twisting of the covering yarn B1 itself and the covering twist of the covering yarn B1 on the covering yarn B2. Therefore, the twist ratio η of the covered yarn C3 to the rope D can only be the ratio of the twist of the covering yarn B1 on the covering yarn B2 to the twist of the rope D, and the calculation formula is:

[0082]

[0083] To sum up, the present utility model can produce three covered yarns C1, C2, and C3 with different structures through the adjustment of simple accessories. By using one or more of the three covered yarns and then covering and twisting the core yarn A, multiple ropes D with different structures can be formed, which can meet the usage requirements under different working conditions.

[0084] In the present utility model, parameters such as the diameters (d1, d2) of the motor pulley and the main shaft pulley of the hollow spindle, the number of teeth (Z1, Z2) of the epicyclic gear and the external gear ring, the speed n of the motor M1, and the speed v of the winding roller can be adjusted to change the twist T1 of the covered yarn C, the covering twist T2 of the rope D, and adjust the twist ratio between the covered yarn C and the rope D, so as to realize the integrated production of double twisting. The structure is simple, the production efficiency is high, the adjustable range of twist is wide, the process adjustment is convenient, and the variety adaptability is strong.

[0085] In the present utility model, an epicyclic gear train mainly composed of a cantilever H, a hollow spindle, an epicyclic gear, an external gear ring, etc. is used to complete the transmission system of multiple doubling twisting mechanisms; a magnetic ring for fixing the covered yarn storage barrel and a yarn guide hook above the doubling twisting mechanism are designed by using the hollow spindle to construct multiple doubling twisting mechanism systems; the integration of multiple doubling twisting mechanisms is realized by using the design of the hollow spindle and multiple doubling twisting systems, and a rope production system is constructed. The present utility model realizes a multi-doubling twisting system with multiple twists per revolution of the main shaft. This multi-doubling twisting system has a simple structure, extremely strong practical value, and is of great significance for the production of ply yarns and ropes.

[0086] In the present utility model, the cantilever multi-doubling twisting mechanism 2 is the core technology. The magnetic ring for fixing the covered yarn storage barrel and the yarn guide hook of the covered yarn rotate synchronously with the cantilever and maintain a stable positional relationship with the position of the covered yarn storage barrel, so as to ensure that each doubling twisting mechanism realizes doubling twisting. This positional relationship is crucial for the realization of the multi-doubling twisting function, and together with the epicyclic gear train transmission system, it forms the twisting and covering structure of the present utility model, and neither can be missing.

[0087] The cable produced by the present utility model has a two-layer structure. The inner layer uses core yarn, and the covering layer uses a structure of multiple covering wires. Each covering wire is formed by twisting multiple yarns, and the multiple covering wires are twisted and covered on the surface of the core yarn. In the cable, the core yarn does not rotate together with the covering wires during twisting, and their movements are independent of each other, which can ensure that the core yarn is covered in the center of the cable. Generally, the linear density and rigidity of the core yarn are relatively large, while the linear density and rigidity of the covering wires are relatively small, which is convenient for the covering wires to cover the core yarn, and the formed cable structure is more stable. The present utility model adopts an epicyclic gear train. Compared with the planetary gear train, on the one hand, a larger transmission ratio can be obtained, and on the other hand, a covering structure cable in which the core yarn does not rotate and the covering wires rotate can be formed. In terms of the design principle, double twisting is designed, and the transmission is carried out by using a cantilever. The epicyclic gear on the cantilever rotates with the rotation of the cantilever to form a revolution. The epicyclic gear meshes with the internal gear ring, causing the epicyclic gear on the cantilever to rotate self, forming a combination of self-rotation and revolution. At the same time, since a relatively large centrifugal force is generated by the yarn storage barrel on the double twister spindle when the double twister spindle on the epicyclic gear makes a revolution, which affects the stability of the equipment and the wear of the structure. By setting the internal gear ring and the epicyclic gear to mesh with each other, the internal gear ring can provide support to avoid the double twister spindle from bearing a large shear stress at the cantilever, which can further improve the rotation stability of the double twister spindle and reduce the wear of the equipment. Moreover, the hollow spindle of the cantilever of the present utility model adopts a hollow design, and a yarn guide hook at the top of the double twister spindle and a magnetic ring for fixing the yarn barrel are arranged by using the hollow spindle, forming a double twister spindle with one revolution and two twists. The revolution of the double twister spindle completes the twisting of the covering wires on the core yarn, with one revolution and one twist. By using the transmission ratio design of the cantilever and the double twister spindle, the technical effect of multi-fold high-efficiency twisting can be achieved through two twists.
