Description

Technical Field

[0001] The invention relates to the technical field of texturing machines, and in particular to a false twisting device and method for a high-speed texturing machine for improving false twist balance. Background Art

[0002] In the high-speed texturing process, false twisting is a key link that affects the quality of DTY (drawn textured yarn). During high-speed operation, there may be slight differences in the speed, stretching force and other factors between the transmission components, which leads to uneven false twisting of the fibers, thus affecting the twist stability, elasticity and strength of the yarn. However, the traditional texturing machine is still relatively rough in controlling the false twist balance, which is difficult to meet the production needs of high-quality yarn.

[0003] For example, Chinese patent authorization announcement number CN217149457U discloses a false twist device for a coating texturizing machine. In the prior art, three rotating shafts are usually used, and multiple friction disks are arranged axially on each rotating shaft, and the three rotating shafts are distributed in a herringbone shape. In order to ensure that the friction disks on the three rotating shafts can operate synchronously, a synchronization mechanism is generally set up. The synchronization mechanism mostly uses a synchronous belt or gear transmission to keep the three friction disks rotating in the same direction. When the fiber bundle passes through the friction disks on the three rotating shafts, the friction disks apply pressure to the fiber bundle by rotating to achieve uniform friction, thereby giving the fiber an appropriate false twist, thereby changing the internal structure of the bundle and improving the elasticity of the yarn.

[0004] However, in actual use, due to the continuous friction between the fiber bundle and the friction disk, even if the friction disk is made of wear-resistant material, it will inevitably wear out after long-term use. In order to ensure the balance of false twist, the flatness of the friction disk on the three axes is crucial. Once the surface of the friction disk is uneven due to wear, the false twist effect may deviate, thereby affecting the quality stability of the yarn and reducing the yield rate. Therefore, how to optimize the durability of the friction disk and maintain the false twist stability after long-term operation has become a key technical problem in improving the production efficiency of high-quality elastic yarn. Summary of the invention

This method of switching the contact surface between the friction disk and the silk thread by adjusting the angle of the friction disk balances the wear of the friction disk, improves the stability of false twist, and at the same time extends the service life of the friction disk and reduces the maintenance frequency.

[0007] Preferably, there are three friction discs, which are arranged on the mounting frame at equal intervals in the vertical direction, the axes of the friction discs are parallel to each other, and the friction discs can synchronously adjust the contact position with the wire as the axis angle of the drive shaft changes.

[0014] Preferably, a slide rail extending radially along the through hole is provided on the base, the mounting frame is slidably disposed on the slide rail, and a linear drive for driving the mounting frame to move is provided below the base.

[0015] A false twisting method for a texturing machine, applied to the false twisting device of a high-speed texturing machine for improving false twist balance, comprises the following steps: S1, introducing the wire from the through hole of the base so that the wire is located between the three friction discs, and the end of the wire is wound up by a winding device in a subsequent process; S2, adjusting the distance between the friction disc and the wire by sliding the mounting frame along the radial direction of the through hole, so that the three friction discs are staggeredly arranged around the wire; S3, start the driving shaft, the driving shaft rotates to drive the friction disk to rotate, and at the same time the winding device continuously winds up and drives the silk thread to pass through the friction disk, and the friction disk performs false twisting operation on the passing silk thread; S4a. When the friction disc is worn, the drive shaft is controlled to rotate around the connection point between the drive shaft and the mounting bracket, driving the friction disc to rotate, changing the angle between the axis of the friction disc and the axis of the through hole, so that the unworn or less worn side of the upper outer edge and the lower outer edge of the friction disc contacts the wire; S4b. While adjusting the angle of the friction disc, the mounting bracket is controlled to move radially along the through hole to compensate for the offset of the contact position with the wire caused by the change in the angle of the friction disc.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adjusts the driving shaft so that the driving shaft can rotate around the connection point between the driving shaft and the mounting frame, thereby driving the friction disc connected to the driving shaft to rotate, so as to achieve the adjustment of the angle between the axis of the friction disc and the axis of the through hole, so that the friction disc can achieve that only one side of its upper outer edge and lower outer edge contacts the silk thread through the adjustment of the angle. This method of switching the contact surface between the friction disc and the silk thread by adjusting the angle of the friction disc balances the wear of the friction disc, improves the stability of false twisting, and at the same time prolongs the service life of the friction disc and reduces the maintenance frequency; 2. The present invention compensates for the position deviation caused by the angle change of the friction disk by the radial sliding of the mounting frame along the through hole, so that the silk thread can always receive a uniform false twist force from the friction disk. This automatic compensation method effectively improves the problem of uneven false twist force of traditional false twist machines, avoids the instability of false twist caused by the position deviation of the silk thread, and improves the processing quality of the silk thread; 3. The present invention supports the friction disc through the connector, and cooperates with the arrangement of the guide rail and the support frame, so that the friction disc can only be adjusted in the vertical direction, thereby ensuring the contact distance between the multiple friction discs and the screw rod. During the false twisting process of the silk thread passing through the friction disc, the friction disc will adjust its axis according to the angle of the drive shaft to ensure that one of the upper outer edge and the lower outer edge of the friction disc is in contact with the silk thread, thereby balancing the wear of the friction disc, extending the service life of the friction disc, and improving the stability of the false twisting operation. At the same time, it is convenient to replace each friction disc separately, avoiding the need to remove all friction wheels on the drive shaft when replacing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figures 1 to 7 , Fig.11 and Fig.12 As shown: a false twisting device of a high-speed texturing machine for improving false twist balance, comprising a base 1 and a through hole 11 arranged in the center of the base 1 for silk thread to pass through, three mounting brackets 2 that can slide along the radial direction are evenly distributed around the circumference of the through hole 11, each mounting bracket 2 is provided with a driving shaft 3 that is rotatably connected to it, and the driving shaft 3 is provided with at least one friction disk 21 that is transmission-connected to it; the driving shaft 3 can rotate around the connection point between it and the mounting bracket 2 to change the angle between the axis of the friction disk 21 and the axis of the through hole 11, and the upper outer edge and the lower outer edge of the friction disk 21 can respectively perform false twisting operation on the silk thread by adjusting the angle of the friction disk 21, and at the same time, when adjusting the angle of the friction disk 21, the mounting bracket 2 can move along the radial direction of the through hole 11 to compensate for the deviation of the contact position with the silk thread caused by the change of the angle of the friction disk 21.

[0021] First embodiment: The silk thread is introduced into the false twisting device from the through hole 11 in the center of the base 1, and will pass through the friction discs 21 on the three mounting frames 2 in sequence, so that the end of the silk thread can be wound up by the winding device of the subsequent process, and the three friction discs 21 will be staggeredly arranged on the side of the silk thread. At this time, the driving shaft 3 is started, and the rotation of the driving shaft 3 drives the rotation of the friction disc 21 connected to it (the friction disc 21 is directly sleeved on the driving shaft 3). The winding device continuously winds up and drives the silk thread to pass through the friction disc 21, so that the rotating friction disc 21 can perform false twisting operation on the passing silk thread.

[0022] The friction disc 21 of the conventional false twisting machine will wear out during the contact with the silk thread (the axis of the friction disc 21 is parallel to the axis of the through hole 11), so that the service life of the friction disc 21 is limited and needs to be replaced and maintained regularly. After the friction disc 21 of the false twisting device of the present invention is worn out, the drive shaft 3 is adjusted so that the drive shaft 3 can rotate around the connection point between the drive shaft 3 and the mounting frame 2, thereby driving the friction disc 21 connected to the drive shaft 3 to rotate, so as to achieve the adjustment of the angle between the axis of the friction disc 21 and the axis of the through hole 11, so that the friction disc 21 can achieve only one side of its upper outer edge and lower outer edge contacting with the silk thread through the adjustment of the angle. It should be noted that the friction disc 21 is in an inclined state in the initial state, that is, the upper outer edge or the lower outer edge of the friction disc 21 contacts with the silk thread. This method of switching the contact surface of the friction disc 21 and the silk thread by adjusting the angle of the friction disc 21 balances the wear of the friction disc 21, improves the stability of false twisting, and at the same time prolongs the service life of the friction disc 21 and reduces the maintenance frequency.

[0023] Since the angle change of the friction disc 21 will affect the contact position between the friction disc 21 and the silk thread (angle adjustment will make the friction discs 21 on the three mounting frames 2 move away from or closer to the through hole 11, thereby changing the contact force and position between the friction discs 21 and the silk thread), the mounting frame 2 slides radially along the through hole 11 to compensate for the position deviation caused by the angle change of the friction disc 21, so that the silk thread can always receive a uniform false twist force from the friction disc 21. This automatic compensation method effectively improves the problem of uneven false twist force of traditional false twisting machines, avoids the instability of false twisting caused by the position deviation of the silk thread, and improves the processing quality of the silk thread. Since the angle of the friction disc 21 is adjustable and the mounting frame 2 can slide to adjust the position, there is no need for a complicated disassembly and assembly process when replacing and maintaining the friction disc 21. It not only shortens the equipment maintenance time, but also reduces the difficulty of manual operation and improves production efficiency.

[0024] like Figures 1 to 5 , Fig.11 and Fig.12As shown: there are three friction discs 21, which are arranged on the mounting frame 2 at equal intervals in the vertical direction, the axes of the friction discs 21 are parallel to each other, and the friction discs 21 will synchronously adjust the contact position with the wire as the axis angle of the drive shaft 3 changes.

[0025] When the drive shaft 3 is started, it drives the friction disc 21 to rotate, so that the silk thread is subjected to false twisting when passing through the friction disc 21. Since the axis of the friction disc 21 will change synchronously with the axis angle of the drive shaft 3, one of the upper outer edge or the lower outer edge of the friction disc 21 will contact the silk thread. Unlike the conventional friction disc 21 with a fixed axis, the present device adjusts the angle of the axis of the friction disc 21 to keep the silk thread in the optimal false twisting position at all times, ensure balanced false twisting force, and improve false twisting stability. The wear of the friction disc 21 is balanced, and compared with the conventional false twisting method of fixing the friction disc 21, the service life of the friction disc 21 is effectively extended, and the maintenance requirements are reduced.

[0026] Second embodiment: In order to further improve the false twisting effect on the silk thread, three friction discs 21 can be arranged on the driving shaft 3. However, if the solution in the first embodiment in which the friction disc 21 is directly sleeved on the driving shaft 3 is adopted, when the axis of the driving shaft 3 is tilted, the three friction discs 21 will be driven to tilt together. Since the three friction discs 21 are not in the same vertical direction, the three friction discs 21 on the same driving shaft 3 cannot operate on the silk thread at the same time. Therefore, the three friction discs 21 need to be distributed at equal intervals in the vertical direction, and the axes of the three friction discs 21 are parallel to each other, so that the three friction discs 21 can operate on the passing silk thread, so that the silk thread is always subjected to uniform false twisting force during the entire false twisting process, avoiding false twist instability caused by contact position offset, and improving the processing quality of the silk thread.

[0027] like Figures 3 to 9 As shown: the mounting frame 2 is provided with a guide rail 22 extending in the vertical direction, the guide rail 22 is provided with a support frame 23 which is slidably matched with the guide rail 22, the support frame 23 and the guide rail 22 are in damping sliding cooperation, the support frame 23 is provided with a connecting head 231 which is rotatably connected with the support frame 23 and is used to support the friction disk 21, the drive shaft 3 is provided with a transmission shaft 232 which is used to transmit power to the friction disk 21 on the connecting head 231, and the transmission shaft 232 is a retractable structure.

[0028] The friction disc 21 is supported by the connector 231, and the guide rail 22 and the support frame 23 are arranged so that the friction disc 21 can only be adjusted in the vertical direction, thereby ensuring the contact distance between the multiple friction discs 21 and the silk thread. When the silk thread passes through the friction disc 21 for false twisting, the friction disc 21 will adjust its axis according to the angle of the drive shaft 3 to ensure that one of the upper outer edge and the lower outer edge of the friction disc 21 is in contact with the silk thread, thereby balancing the wear of the friction disc 21, extending the service life of the friction disc 21, and improving the stability of the false twisting operation.

[0029] The transmission shaft 232 is driven by the change in the angle of the driving shaft 3, and the connecting head 231 is driven by the transmission shaft 232 to rotate on the support frame 23, so that the axis of the friction disc 21 can be adjusted. Since the friction disc 21 is supported by the connecting head 231, and the support frame 23 can slide along the guide rail 22, the friction disc 21 installed on the connecting head 231 can only move in the vertical direction, ensuring that after the axis angle of the friction disc 21 is adjusted, the contact distance between the outer edges of multiple friction discs 21 and the silk thread is kept consistent, avoiding the need to adjust multiple friction discs 21, and the false twist balance of the silk thread will not be affected due to the adjustment of the angle.

[0030] At the same time, in order to ensure that the friction disk 21 can still obtain stable power when the angle of the drive shaft 3 changes, the transmission shaft 232 adopts a retractable structure so that when the axis of the drive shaft 3 changes, it can still effectively transmit the power of the drive shaft 3 to the friction disk 21, so that the friction disk 21 can rotate normally to ensure the continuous stability of the false twisting operation.

[0031] like Figures 1 to 4 , Figures 6 to 9 As shown, the driving shaft 3 is provided with driving frames 31 having the same number as the friction discs 21 and corresponding to each other, and the driving frames 31 are provided with first transmission components 311 for driving the transmission shaft 232 to rotate.

[0032] During the false twisting process, the silk thread will pass through multiple friction discs 21 in sequence, and the rotation of the drive shaft 3 will drive the friction discs 21 to perform false twisting on the silk thread. Since the axial angle of the drive shaft 3 will change, the movement of the drive shaft 3 will drive the drive frame 31 to move accordingly, and drive the transmission shaft 232 connected thereto to adjust its position synchronously (one end of the transmission shaft 232 can be rotatably mounted on the drive frame 31), so that it can still maintain stable power transmission during the movement of the drive frame 31. At the same time, due to the setting of the support frame 23 and the guide rail 22, the friction disc 21 can only slide in the vertical direction, so that the distance between the friction disc 21 and the silk thread changes and remains fixed. The transmission shaft 232 can ensure that the friction disc 21 always obtains a stable driving force by virtue of its own telescopic performance, thereby ensuring the continuity of the false twisting process and improving the processing quality.

[0033] When the drive shaft 3 rotates, the first transmission assembly 311 on the drive frame 31 is started, and the transmission shaft 232 is driven to rotate through the assembly. The first transmission assembly 311 can adopt a bevel gear transmission method, wherein a first bevel gear 3111 is provided on the drive frame 31 to be connected to the drive shaft 3, and a second bevel gear 3112 is provided on the side of the first bevel gear 3111 to be meshed with the first bevel gear 3111, and the second bevel gear 3112 is sleeved on the transmission shaft 232. Through the mutual meshing of the first bevel gear 3111 and the second bevel gear 3112, stable power transmission is achieved, thereby driving the friction disk 21 to operate. In addition, the first transmission assembly 311 can also adopt a universal joint structure to meet the adjustment requirements of a larger angle, ensure the reliability and flexibility of power transmission, and further improve the stability and efficiency of false twisting operation.

[0034] like Figures 6 to 9 As shown: the driving frame 31 can also slide along the axial direction of the driving shaft 3, and a first screw rod 32 parallel to its axis is arranged on the side of the driving shaft 3, and the driving frame 31 is respectively sleeved on the first screw rod 32 and the driving shaft 3, and the driving frame 31 and the first screw rod 32 are threadedly matched.

[0035] By setting the first screw rod 32, when the first screw rod 32 rotates, the position of the drive frame 31 on the drive shaft 3 can be accurately adjusted, so that the power transmission position of the transmission shaft 232 is more accurate. Compared with the traditional fixed installation, this adjustment method not only provides higher flexibility, but also ensures the stability of the adjustment process, avoiding the uneven false twisting effect caused by improper adjustment. In addition, a spline connection is adopted between the drive frame 31 and the drive shaft 3, a spline groove (not shown in the figure) is provided on the drive shaft 3, and a bearing is provided on the drive frame 31, and a spline matching the spline groove is provided on the bearing (not shown in the figure), so that the drive frame 31 can still maintain the synchronous rotation of the bearing during the sliding process along the drive shaft 3, so that the power can be transmitted to the friction disk 21 through the transmission shaft 232, thereby avoiding the situation of power transmission lag or instability.

[0036] When the position of the driving frame 31 on the driving shaft 3 is adjusted, the transmission shaft 232 will move with the movement of the driving frame 31, thereby driving the support frame 23 on the guide rail 22 to move through the other end of the transmission shaft 232, so that the support frame 23 slides along the guide rail 22, thereby changing the position of the friction disc 21 on the guide rail 22. In this way, the spacing between multiple friction discs 21 can be accurately adjusted, so that the friction discs 21 maintain the same distance to meet different silk processing requirements, improve the adaptability and consistency of the false twisting process, reduce the difficulty of adjustment caused by equipment limitations, improve production efficiency and reduce maintenance costs.

[0037] like Figures 2 to 4 and Figures 6 to 9As shown, the friction disc 21 is rotatably arranged on the top of the connecting head 231 , and the connecting head 231 is provided with a second transmission assembly 2311 which is transmission-connected to the transmission shaft 232 .

[0038] The two ends of the transmission shaft 232 are rotatably arranged on the driving shaft 3 and the connector 231, respectively. The second transmission assembly 2311 can adopt a bevel gear meshing transmission mode, wherein a third bevel gear 23111 is arranged on one end of the transmission shaft 232 close to the connector 231, and a fourth bevel gear 23112 meshingly connected therewith is arranged beside the third bevel gear 23111, and a mounting shaft 2312 that can drive the friction disk 21 to rotate is arranged on the connector 231, and the fourth bevel gear 23112 is sleeved on the transmission shaft 232. When the transmission shaft 232 rotates, the third bevel gear 23111 will drive the fourth bevel gear 23112 to rotate, and the fourth bevel gear 23112 drives the rotation of the mounting shaft 2312, thereby driving the friction disk 21 to rotate, and realizing the false twisting effect on the silk thread. Ensure the stable rotation of the friction disk 21, so that the silk thread is more evenly stressed during the false twisting process, avoid the silk thread tension fluctuation caused by unstable transmission, thereby improving the quality and consistency of the finished silk thread.

[0039] In addition, in order to improve the flexibility of transmission, the second transmission assembly 2311 can also adopt a universal joint structure to adapt to the power transmission requirements under different working conditions. The universal joint can compensate for the angle deviation between the transmission shaft 232 and the friction plate 21, ensure stable power transmission, effectively reduce the additional resistance caused by angle changes, and improve transmission efficiency and equipment life.

[0040] like Figures 6 to 9 As shown, each connector 231 is provided with a fixing pin 2313 for limiting the friction disc 21 .

[0041] The fixing pin 2313 can be installed by means of snap-fit ​​or threaded fitting. By setting the fixing pin 2313, it is possible to ensure that the friction disc 21 maintains a stable axial position during operation, and avoid axial displacement of the friction disc 21 due to high-speed rotation or external interference, thereby affecting the accuracy and stability of the false twisting process. It ensures that the silk thread is evenly stressed during the false twisting process, thereby improving the processing quality. It can not only achieve rapid disassembly and maintenance, but also provide high-strength fixed support to improve the adaptability of the equipment. It is helpful for rapid replacement or adjustment, improves the operating efficiency of the production line, and reduces downtime caused by equipment maintenance.

[0042] At the same time, since each connector 231 is individually mounted with a friction disc 21 , the device can avoid the need to remove all friction discs 21 on the drive shaft 3 when replacing the friction disc 21 , thereby improving the efficiency of maintenance.

[0043] like Figures 1 to 4 and Figures 6 to 9 As shown: a fixing frame 33 rotatably arranged on the mounting frame 2 is provided at the bottom of the driving shaft 3, a mounting plate 331 extending downwardly to the bottom of the base 1 is provided on the fixing frame 33, an avoidance groove 12 for avoiding the mounting plate 331 is provided on the base 1, and a driving component 333 for driving the mounting plate 331 to move is provided below the base 1.

[0044] During the operation of the false twisting device, the bottom of the driving shaft 3 is rotatably mounted on the mounting frame 2 through the fixing frame 33, so that the axis of the driving shaft 3 can be adjusted. The fixing frame 33 is provided with a first rotary drive motor 332 for driving the driving shaft 3 to rotate, ensuring that the axis of the driving shaft 3 can be driven when it changes. Through the arrangement of the avoidance groove 12 and the mounting plate 331, the fixing frame 33 is provided with a connection end that is convenient for connecting with the driving device.

[0045] The driving device can be set as a cylinder or an electric push rod, the output shaft of the cylinder or the electric push rod is rotatably connected to the mounting plate 331, and the cylinder or the electric push rod is rotatably installed under the base 1. The mounting plate 331 is driven to move by extending the output shaft of the cylinder or the electric push rod, so that the fixed frame 33 can rotate around the connection point between it and the base 1, thereby realizing the axis adjustment of the drive shaft 3.

[0046] Thereby, the axial angle of the driving shaft 3 can be precisely adjusted to meet different false twisting requirements, while ensuring the stability of power transmission and improving the uniformity of the false twisting of the silk thread.

[0047] At the same time, a first gear 3331 fixedly connected to the mounting plate 331 can also be provided, and a rack 121 meshingly connected to the first gear 3331 is provided below the avoidance groove 12, so that when the mounting frame 2 slides radially along the through hole 11, the first gear 3331 will roll along the rack 121 (when the rack 121 is fixed, the first gear 3331 will perform both translational and rotational motion). Since the first gear 3331 is fixedly connected to the mounting plate 331, the rotation of the first gear 3331 will be directly converted into the swing of the fixing frame 33 around the connection point between it and the mounting frame 2, thereby realizing the axial angle adjustment of the drive shaft 3.

[0048] It should be noted that when the mounting frame 2 moves in a radial straight line, it will drive the overall translation of the fixing frame 33. When the first gear 3331 moves in an arc trajectory due to the change of the axis of the driving shaft 3, the linear movement of the mounting frame 2 will reversely adjust the position of the first gear 3331, partially offset the deviation between the arc trajectory and the straight line of the rack 121, maintain the meshing state of the first gear 3331 and the rack 121, and avoid the first gear 3331 and the rack 121 from getting stuck. In this way, the driving of the angle change of the driving shaft 3 can be achieved without adding driving equipment, reducing the investment in equipment costs.

[0049] like Figures 1 to 4 and Figures 6 to 9 As shown: a slide rail 13 extending radially along the through hole 11 is arranged on the base 1, the mounting frame 2 is slidably arranged on the slide rail 13, and a linear drive 131 for driving the mounting frame 2 to move is arranged below the base 1.

[0050] The linear drive 131 provides power to drive the mounting frame 2 to move precisely along the slide rail 13, thereby adjusting the position of the drive shaft 3 and related components to adapt to different false twisting operation requirements of the silk thread and ensure the contact stability between the friction disc 21 and the silk thread. The linear drive 131 preferably adopts an electric cylinder, a ball screw drive mechanism, a cylinder or a hydraulic cylinder to provide different driving force and precision options.

[0051] like Figures 1 to 7 , Fig.11 and Fig.12 As shown: A false twisting method for a texturing machine, applied to the above-mentioned false twisting device for a high-speed texturing machine to improve the false twist balance, comprises the following steps: S1, introducing the wire from the through hole 11 of the base 1, so that the wire is located between the three friction discs 21, and the end of the wire is wound up by the winding device of the subsequent process; S2, adjusting the distance between the friction disc 21 and the thread by sliding the mounting frame 2 along the radial direction of the through hole 11, so that the three friction discs 21 are staggeredly arranged around the thread; S3, start the drive shaft 3, the drive shaft 3 drives the friction disk 21 to rotate, and at the same time the winding device continuously winds up and drives the silk thread to pass through the friction disk 21, and the friction disk 21 performs a false twist operation on the passing silk thread; S4a, when the friction disc 21 is worn, the drive shaft 3 is controlled to rotate around the connection point between the drive shaft 3 and the mounting bracket 2, driving the friction disc 21 to rotate, changing the angle between the axis of the friction disc 21 and the axis of the through hole 11, so that the unworn or less worn side of the upper outer edge and the lower outer edge of the friction disc 21 contacts the wire; S4b, while adjusting the angle of the friction disc 21, the mounting bracket 2 is controlled to move along the radial direction of the through hole 11 to compensate for the deviation of the contact position with the wire caused by the change in the angle of the friction disc 21;

[0052] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
