Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mechanical equipment especially to a motor coil interval paper hot press forming ultrasonic wave welding packing equipment. BACKGROUND

[0002] The motor coil interval paper is used for insulating between two adjacent coils of a motor, preventing the two adjacent coils from causing insulation failure due to damage of the varnished wire paint.

[0003] The motor coil interval paper comprises two parts, namely, slot inner interval paper and slot outer interval paper, and is composed of the slot inner interval paper and the slot outer interval paper bonded together. In current production of the motor coil interval paper on the assembly line of most factories, the slot inner interval paper and the slot outer interval paper are first cut into a specific size by manual operation, and then the slot inner interval paper is folded and cut to form a notch, and the slot outer interval paper is bonded together by double-sided adhesive. Due to the fatigue, emotional fluctuation, or skill difference of manual operation, the size of the cut and the size of the bonded position have large errors, and the manual operation bonds the motor coil interval paper by the double-sided adhesive, so that the strength of the motor coil interval paper is not enough, thereby the quality of the produced motor coil interval paper cannot meet the standard, and the motor coil interval paper often falls off when used in the motor, causing serious problems such as poor insulation of the motor. SUMMARY

[0004] In order to improve the production quality of the motor coil interval paper and solve the problem of poor insulation when the motor coil interval paper is used in the motor, the utility model provides a motor coil interval paper hot press forming ultrasonic wave welding packing equipment.

[0005] In the first aspect, the utility model provides a motor coil interval paper hot press forming ultrasonic wave welding packing equipment, adopts the following technical scheme:

[0006] A motor coil interval paper hot press forming ultrasonic wave welding packing equipment comprises:

[0007] A paper feeding mechanism is used for pushing the slot inner interval paper and the slot outer interval paper;

[0008] A hot press forming mechanism is used for heating and press forming the slot inner interval paper pushed out by the paper feeding mechanism;

[0009] An ultrasonic wave welding mechanism is used for welding the slot outer interval paper and the slot inner interval paper after hot press forming;

[0010] A traction mechanism is used for transferring and stacking the motor coil interval paper after welding;

[0011] A packing mechanism is used for packing the motor coil interval paper after stacking.

[0012] By adopting the technical scheme, after the operator installs the inner slot paper and the outer slot paper on the paper feeding mechanism, the inner slot paper and the outer slot paper can sequentially pass through the delivery of the paper feeding mechanism, the heating and forming of the heating and forming mechanism, the welding of the ultrasonic welding mechanism, the traction of the traction mechanism to the packaging mechanism for packaging and other automatic processes. In this process, in addition to the step of installing the roll paper on the paper feeding mechanism, the other steps can be automatically completed without manual intervention, and the efficiency and accuracy are greatly improved. Moreover, the connection between the inner slot paper and the outer slot paper is replaced by the ultrasonic welding process instead of double-sided adhesive tape, and the firmness is better. The motor coil spacing paper is not easy to fall off when used in the motor.

[0013] Optionally, the paper feeding mechanism includes a rotating wheel for installing the roll paper, a paper feeding wheel set for feeding the paper, a paper discharging wheel set for discharging the paper, and a proximity switch for detecting the amount of roll paper and stopping when the roll paper is used up. The paper feeding wheel set includes a paper feeding wheel, a paper feeding motor for driving the paper feeding wheel to rotate, and a pressing wheel for pressing the paper to the paper feeding wheel. The roll paper is installed on the rotating wheel and sequentially passes through the proximity switch, the paper feeding wheel set and the paper discharging wheel set.

[0014] By adopting the technical scheme, when the roll paper is installed on the rotating wheel, the paper feeding motor of the paper feeding wheel set moves to draw the roll paper from the rotating wheel through the feeding wheel. When the proximity switch detects that the roll paper on the rotating wheel is used up, the proximity switch drives the paper feeding motor to stop running. At this time, the pressing wheel in the paper feeding wheel set can press the residual roll paper on the paper feeding wheel without making the residual roll paper enter the subsequent processing mechanism, thereby avoiding the mixing of the insufficient length roll paper into the previously processed motor coil spacing paper for packaging together, and improving the quality of the motor coil spacing paper.

[0015] Optionally, the heating and forming mechanism includes a forming drive mechanism for feeding the paper and a guide module arranged on both sides of the forming drive mechanism. The guide module is horizontally provided with a conveying groove for the paper to pass through. The forming drive mechanism includes a drive wheel set, a drive motor connected to the drive wheel set through a gear transmission structure for driving the drive wheel set to rotate, and a pressing assembly for pressing the drive wheel set.

[0016] By adopting the technical scheme, the paper from the paper feeding mechanism enters the guide module from the conveying groove and passes through the drive wheel set, and the drive wheel set drives the roll paper to move through the drive wheel set. The drive wheel set presses the roll paper through the pressing assembly, so that the roll paper is not easy to slip during movement, thereby improving the accuracy of the length control of the roll paper. When the roll paper is used up and a part of the residual roll paper is stuck in the heating and forming mechanism, the drive wheel set adjusts the tightness through the pressing assembly, so that the residual roll paper can be drawn out of the heating and forming mechanism, which is more convenient.

[0017] Optionally, the driving wheel set comprises vertically distributed upper and lower pressing wheels, the upper pressing wheel is circumferentially provided with a shaped convex ring, the cross section of the shaped convex ring is trapezoidal, having a horizontal plane and inclined planes on both sides of the horizontal plane; the lower pressing wheel is circumferentially provided with a shaped concave groove in a concave shape, which cooperates with the shaped convex ring.

[0018] The conveying channel comprises a horizontal passage provided on one side of the guide module and having a cross section shape matching that of the paper roll before shaping, and a U-shaped passage provided on the other side of the guide module and having a cross section shape matching that of the paper roll after shaping.

[0019] The guide module is provided on the side where the horizontal passage is provided with a heating rod for heating the paper roll in the horizontal passage.

[0020] By adopting the above technical solution, the paper roll enters the horizontal passage and is heated by the heating rod, the heated paper roll enters the driving wheel set and is hot-pressed by the upper and lower pressing wheels to form a specific cross section shape, and the shaped paper roll finally enters the U-shaped passage for conveying and is cut by the cutting assembly.

[0021] After the in-slot spacer paper is hot-pressed, the material hardness of the in-slot spacer paper can be increased, and when the in-slot spacer paper is cut by the cutting assembly, the in-slot spacer paper is less likely to deform, thereby improving the cutting size accuracy of the in-slot spacer paper. Moreover, the in-slot spacer paper has a certain temperature after hot-pressing, and when the in-slot spacer paper enters the U-shaped passage, the temperature of the in-slot spacer paper can be dissipated by the guide module in the U-shaped passage, so that the temperature of the in-slot spacer paper reaches the ideal welding temperature when the in-slot spacer paper reaches the ultrasonic welding mechanism, thereby improving the welding strength of the ultrasonic welding.

[0022] Optionally, the cutting assembly comprises a lifting seat, an upper cutter for cutting the paper roll and sliding up and down on the lifting seat, and a lower pressing driving element for driving the upper cutter to lift.

[0023] A fixing block for passing and positioning the paper roll is horizontally slidably arranged on the lifting seat, and the side wall of the fixing block abuts against the side wall of the upper cutter; the bottom of the upper cutter has a cutting portion matching the cross section of the paper roll after hot-pressing.

[0024] By adopting the above technical solution, since the in-slot spacer paper has a specific cross section shape after hot-pressing, the cutting portion of the upper cutter is arranged to have a shape matching the cross section shape of the in-slot spacer paper, so that the in-slot spacer paper is less likely to deform when cut by the upper cutter;

[0025] By setting the fixed block, the fixed block can position the paper roll, so that the slot inner spacer paper is aligned with the edge of the cutting part, so that the slot inner spacer paper is not easy to be cut; and after the fixed block abuts against the upper cutter, the upper cutter can slide along the side wall of the fixed block during cutting, so that the upper cutter can cut the slot inner spacer paper extending outside the fixed block neatly and can ensure the accuracy.

[0026] Optionally, the cutting assembly further comprises a lower cutter located below the upper cutter and used for cutting the paper roll from below during cutting of the paper roll, and a jacking driving element for driving the lower cutter to ascend and descend; the lower cutter has a clamping groove matched with the cutting part, and a displacement groove is formed at the bottom of the clamping groove; the side wall of the lower cutter abuts against the side wall of the fixed block.

[0027] By adopting the above technical solution, when cutting the slot inner spacer paper, the lower cutter is first jacked to pre-cut the cutting edge of the slot inner spacer paper, and then the upper cutter is pressed down to cut the uncut part of the bottom edge of the slot inner spacer paper, so that the slot inner spacer paper is completely cut. The above segmented cutting method is less likely to deform the slot inner spacer paper compared with the method of cutting only by the upper cutter.

[0028] Optionally, the cutting assembly comprises an oblique cutter, a lifting driving element for driving the oblique cutter to ascend and descend, and a cutter seat matched with the oblique cutter and used for guiding and positioning the slot outer spacer paper; the oblique cutter has an obliquely formed cutting edge part.

[0029] By adopting the above technical solution, after the slot outer spacer paper comes out of the guide module, it is positioned by the cutter seat to facilitate alignment of the slot outer spacer paper with the oblique cutter, so that the oblique cutter is less likely to cut the slot outer spacer paper askew; and since the slot outer spacer paper is planar, the cutting edge part does not need to be matched with the cross-sectional shape of the slot outer spacer paper, and the cutting edge part is obliquely formed. The bottom tip of the cutting edge part first abuts against one side of the slot outer spacer paper under the driving of the lifting driving element, and the oblique cutting edge moves from one side to the other side of the slot outer spacer paper during the descent of the cutting edge part, thereby cutting the slot outer spacer paper; and when the ultrasonic welding mechanism presses the slot inner spacer paper against the slot outer spacer paper, the slot outer spacer paper is in a straightened and tightened state, and it is relatively simple to cut from one side to the other side of the slot outer spacer paper by the oblique cutting edge at this time. The above cutting method for the planar slot outer spacer paper is relatively simple, and the slot outer spacer paper is less likely to deform.

[0030] Optionally, the ultrasonic welding mechanism comprises a welding base and an ultrasonic welding machine, the ultrasonic welding machine has a welding head for welding the slot inner spacer paper and the slot outer spacer paper; the welding base is perpendicular to the line connecting the guide module for conveying the slot inner spacer paper and the guide module for conveying the slot outer spacer paper.

[0031] Optionally, the traction mechanism comprises a screw rod base, a screw rod assembly rotatably installed on the screw rod base, a screw rod motor for driving the screw rod assembly, and a clamping assembly slidably installed on the screw rod assembly and used for traction of the motor coil spacing paper after completion of welding; the screw rod assembly is parallel to the guide module for conveying the slot spacing paper.

[0032] By using the above technical scheme, after the motor coil spacing paper is completed, the clamping assembly can be tractioned to the packaging mechanism along the length direction of the screw rod assembly, and in the traction process, the slot spacing paper is straightened and tightened, and at this time, the slot spacing paper is cut by the cutting assembly, so that the slot spacing paper is not easy to deform and is convenient to cut under the horizontal tension.

[0033] Optionally, the packaging mechanism comprises a packaging table, a bundling assembly, and a horizontal and vertical driving assembly for driving the bundling assembly to move horizontally and vertically on the packaging table; the packaging table has a packaging area, and the packaging area is located below the clamping assembly.

[0034] In summary, the utility model has at least one of the following beneficial technical effects:

[0035] 1. The motor coil spacing paper hot-press forming ultrasonic welding packaging equipment can immediately stop the transmission of the roll paper when the roll paper is used up, and the residual roll paper is not easy to enter the ultrasonic welding mechanism for welding, thereby avoiding the influence of the residual roll paper on the size of the motor coil spacing paper after completion of welding.

[0036] 2. The material hardness of the slot spacing paper can be increased after hot-press forming, the slot spacing paper is convenient to cut and not easy to deform, and after hot-press forming, the slot spacing paper can be cooled through the U-shaped channel, so that the temperature of the slot spacing paper reaches the ideal welding temperature when the slot spacing paper reaches the ultrasonic welding mechanism, thereby improving the welding strength of the ultrasonic welding.

The slot spacing paper is cut by the beveling cutter, and the slot spacing paper is straightened and tightened to facilitate cutting when the ultrasonic welding mechanism is welded; the slot spacing paper is cut by the cooperation of the upper cutter and the lower cutter, and the slot spacing paper is straightened and tightened to facilitate cutting when the traction mechanism tractions the motor coil spacing paper.

DETAILED DESCRIPTION

[0047] The utility model will be described in further detail below in combination with the drawings and examples.

[0048] The utility model provides a motor coil interval paper hot-press forming ultrasonic welding packaging equipment.

[0049] Reference Figure 1 And Figure 2The motor coil spacing paper hot-pressing forming ultrasonic welding packaging equipment comprises a workbench 1, a protective cover 2, a man-machine interaction system 3 arranged on the protective cover 2, and a paper feeding mechanism 4, a hot-pressing forming mechanism 5, an ultrasonic welding mechanism 6, a traction mechanism 7 and a packaging mechanism 8 arranged on the workbench 1. The protective cover 2 is arranged on the top of the workbench 1 to cover the components on the workbench 1, so as to ensure the safety of the equipment operation. The man-machine interaction system 3 is used for controlling the equipment. The paper feeding mechanism 4 is used for pushing the slot inner spacing paper and the slot outer spacing paper. The hot-pressing forming mechanism 5 is used for heating and press-forming the paper pushed out by the paper feeding mechanism 4. The ultrasonic welding mechanism 6 is used for welding the slot outer spacing paper and the slot inner spacing paper which has completed the hot-pressing forming. The traction mechanism 7 is used for transferring and stacking the motor coil spacing paper which has completed the welding. The packaging mechanism 8 is used for packaging the motor coil spacing paper which has completed the stacking. The paper roll raw material sequentially passes through the processing of the paper feeding mechanism 4, the hot-pressing forming mechanism 5, the ultrasonic welding mechanism 6, the traction mechanism 7 and the packaging mechanism 8, and finally produces the motor coil spacing paper.

[0050] Referring to Figure 2 and Figure 3 In the embodiment, the number of the paper feeding mechanism 4 and the hot-pressing forming mechanism 5 is two, which are respectively used for processing the slot inner spacing paper and the slot outer spacing paper. The hot-pressing forming mechanism 5 used for processing the slot inner spacing paper is different from the hot-pressing forming mechanism 5 used for processing the slot outer spacing paper in structure, which will be introduced in detail in subsequent embodiments.

[0051] The paper feeding mechanism 4 comprises a mounting plate 41, a rotating disc wheel 42, a paper feeding wheel set 43, a paper outlet wheel set 44 and a proximity switch 45. The mounting plate 41 is fixedly installed on the workbench 1 by screws. The rotating disc wheel 42 is rotatably installed on the mounting plate 41, and is used for mounting the paper roll. The proximity switch 45 is located between the rotating disc wheel 42 and the paper feeding wheel set 43, and is used for detecting the remaining amount of the paper roll on the rotating disc wheel 42. The paper outlet wheel set 44 comprises two rollers 441 which abut against each other and are rotatably installed on the mounting plate 41.

[0052] The paper feeding wheel set 43 comprises a paper feeding wheel 431, a paper feeding motor 432 and a pressing wheel 433. The paper feeding wheel 431 is rotatably installed on the mounting plate 41 and is driven to rotate by the paper feeding motor 432. The pressing wheel 433 comprises a rotating shaft 4331 which is rotatable by a torsion spring, a wheel body 4332 which is pressed against the paper feeding wheel 431, and a connecting rod 4333 which connects the rotating shaft 4331 and the wheel body 4332. The wheel body 4332 is rotatable on the mounting plate 41 by the rotating shaft 4331 and is pressed against the paper feeding wheel 431 under the action of the torsion force.

[0053] When the roll paper is installed on the rotating wheel 42, the end of the roll paper passes through the proximity switch 45, the paper feeding wheel set 43 and the paper discharging wheel set 44 in sequence, and finally passes out from between the two rollers 441 of the paper discharging wheel set 44. The pressing wheel 433 can press the roll paper against the paper feeding wheel 431, and the two rollers 441 can clamp the roll paper.

[0054] When the roll paper is used up and the roll paper is not in contact with the proximity switch 45, the proximity switch 45 can drive the paper feeding motor 432 to be closed because the proximity switch 45 is electrically connected with the paper feeding motor 432, so that the roll paper can be immediately stopped from being conveyed.

[0055] Referring to Figure 2 and Figure 4 , the hot-press forming mechanism 5 for processing the out-of-groove spacer paper comprises a forming driving mechanism 51, a guide module 52 and a cutting assembly 53. In the embodiment, the forming driving mechanism 51 for processing the out-of-groove spacer paper is only used to pull the out-of-groove spacer paper to move to the subsequent mechanism.

[0056] The forming driving mechanism 51 comprises a driving wheel set 511, a driving motor 512 and a pressing assembly 513. The driving wheel set 511 comprises two parts of an upper pressing wheel 5111 and a lower pressing wheel 5112 which are vertically distributed and structurally symmetrical. The driving motor 512 is used to drive the driving wheel set 511 to rotate, which is engaged with the driving wheel set 511 through a gear transmission structure 514, and the upper pressing wheel 5111 and the lower pressing wheel 5112 rotate in opposite directions, and the driving wheel set 511 can pull the roll paper when the roll paper passes between the upper pressing wheel 5111 and the lower pressing wheel 5112.

[0057] The pressing assembly 513 comprises a through screw 5131 and a lower pressing spring 5132, the through screw 5131 penetrates the upper pressing wheel 5111 and the lower pressing wheel 5112, and the lower pressing spring 5132 is sleeved on the through screw 5131 and abuts against the top of the upper pressing wheel 5111, so as to press the upper pressing wheel 5111 against the lower pressing wheel 5112.

[0058] The guide module 52 is provided in two numbers and is arranged on both sides of the driving wheel set 511. The guide module 52 is horizontally provided with a conveying slot 521 for guiding the direction of the roll paper. The conveying slot 521 is in the same horizontal position as the gap between the driving wheel set 511, so that the roll paper can enter between the driving wheel set 511 after passing out from the conveying slot 521.

[0059] Referring to Figure 4 and Figure 5The cutting assembly 53 is connected to the tail end of one of the guide modules 52, and is used to cut the paper roll coming out of the guide module 52. The cutting assembly 53 for cutting the out-of-slot spacer paper comprises a lifting seat 531, an oblique cutter 532, a lifting drive 533, and a cutter seat 534. The lifting seat 531 is fixedly installed on the workbench 1, and a straight guide rod 5311 is vertically arranged on the lifting seat 531. The cutter seat 534 is fixedly installed on the lifting seat 531, and a positioning groove 5341 for guiding and positioning the out-of-slot spacer paper is formed in the top of the cutter seat 534. The out-of-slot spacer paper enters the positioning groove 5341 from the conveying groove 521 of the guide module 52. The oblique cutter 532 can cut the out-of-slot spacer paper when the cutter seat 534 abuts against the oblique cutter 532.

[0060] The oblique cutter 532 slides up and down on the straight guide rod 5311 to cut the out-of-slot spacer paper. The lifting drive 533 is fixedly arranged on the lifting seat 531 and drives the oblique cutter 532 to lift up and down. In this embodiment, the lifting drive 533 is in the form of a pneumatic cylinder.

[0061] An edge portion 5321 is obliquely formed in the bottom of the oblique cutter 532. When the oblique cutter 532 cuts the out-of-slot spacer paper, the edge portion 5321 first abuts against one side of the out-of-slot spacer paper, and then moves to the other side during the lifting of the oblique cutter 532, so as to cut the out-of-slot spacer paper.

[0062] Referring to Figure 2 and Figure 6 In this embodiment, the hot-press forming mechanism 5 for processing the in-slot spacer paper is the same as the hot-press forming mechanism 5 for processing the out-of-slot spacer paper, except that the structures of the driving wheel set 511, the guide module 52, and the cutting assembly 53 are different. Therefore, the details are not described herein.

[0063] In the hot-press forming mechanism 5 for processing the in-slot spacer paper, the upper pressing wheel 5111 is circumferentially provided with a forming convex ring 54. The cross section of the forming convex ring 54 is trapezoidal, which is the same as the cross section shape of the in-slot spacer paper after hot-press forming. The lower pressing wheel 5112 is circumferentially provided with a forming concave groove in a concave shape, which is matched with the forming convex ring 54. The forming convex ring 54 has a horizontal plane 541 and two inclined planes 542 located on both sides of the horizontal plane 541. The horizontal plane 541 corresponds to the bottom of the in-slot spacer paper after hot-press forming, and the inclined planes 542 correspond to the side edges of the in-slot spacer paper.

[0064] When the in-slot spacer paper passes through the guide module 52 and enters between the driving wheel set 511, the forming convex ring 54 and the forming concave groove 55 can press the in-slot spacer paper into a specific cross section shape.

[0065] Further, the guide modules 52 on both sides of the driving wheel set 511 have different structures. The guide module 52 close to the paper feeding mechanism 4 is provided with a heating rod 56, which can heat the slot inner spacer paper entering the guide module 52. The conveying channel 521 includes a horizontal channel 522 and a U-shaped channel 523. The horizontal channel 522 is located on the guide module 52 close to the paper feeding mechanism 4, and the U-shaped channel 523 is located on the guide module 52 away from the paper feeding mechanism 4. The horizontal channel 522 has a rectangular cross section, which is used for the slot inner spacer paper with a rectangular cross section to pass through. The U-shaped channel 523 has the same cross section shape as the slot inner spacer paper after hot-press forming, which is used for the slot inner spacer paper after hot-press forming to pass through.

[0066] When the slot inner spacer paper enters from the horizontal channel 522, the heating rod 56 heats the slot inner spacer paper, and the slot inner spacer paper is formed by the extrusion of the forming convex ring 54 and the forming concave groove 55 in the driving wheel set 511. After hot-press forming, the slot inner spacer paper passes through the U-shaped channel 523.

[0067] Referring to Figure 2 and Figure 7 , the cutting assembly 53 for cutting the slot inner spacer paper includes a lifting seat 531, a fixed block 535, an upper cutter 536, a downward driving member 537, a lower cutter 538, and a lifting driving member 539. The fixed block 535 is slidingly installed on the lifting seat 531 and is fixed by screws. The fixed block 535 is used for the slot inner spacer paper to pass through and position the slot inner spacer paper. The upper cutter 536 and the lower cutter 538 are both slidingly lifted on the linear guide rod 5311 of the lifting seat 531. The upper cutter 536 is driven to lift by the downward driving member 537, and the lower cutter 538 is driven to lift by the lifting driving member 539. In this embodiment, the upper cutter 536 and the lower cutter 538 are both in the structure of a pneumatic cylinder.

[0068] The bottom of the upper cutter 536 has a cutting part 5361, which is matched with the cross section shape of the slot inner spacer paper after hot-press forming. The top of the lower cutter 538 is provided with a clamping groove 5381, which is matched with the cutting part 5361. The bottom of the clamping groove 5381 is provided with a clearance groove 5382, which corresponds to the bottom of the slot inner spacer paper, and is used for clearance when cutting the bottom of the slot inner spacer paper.

[0069] The upper cutter 536 and the lower cutter 538 abut against and slide along the side wall of the fixed block 535 when cutting the slot inner spacer paper. When the cutting assembly 53 cuts the slot inner spacer paper, the lower cutter 538 is first lifted by the lifting driving member 539 to make incisions on the two side inclined surfaces 542 of the slot inner spacer paper, and then the upper cutter 536 is lowered by the pressing driving member 537 to cut the bottom of the slot inner spacer paper, so as to cut the slot inner spacer paper.

[0070] The slot inner spacer paper and the slot outer spacer paper are cut at different times, which will be described in subsequent embodiments.

[0071] With reference to Figure 2 and Figure 8 , the ultrasonic welding mechanism 6 comprises a welding base 61 and an ultrasonic welding machine 62, and the ultrasonic welding machine 62 is provided with a welding head 63 for welding the slot inner spacer paper and the slot outer spacer paper. The welding principle of the ultrasonic welding machine 62 is known to those skilled in the art, and will not be described here. The welding base 61 is fixedly installed on the workbench 1, and the line connecting the guide module 52 for conveying the slot inner spacer paper is perpendicular to the line connecting the guide module 52 for conveying the slot outer spacer paper. When the slot inner spacer paper and the slot outer spacer paper are conveyed to the welding base 61, the slot inner spacer paper and the slot outer spacer paper are arranged vertically. When the slot inner spacer paper and the slot outer spacer paper are both conveyed, the welding head 63 presses and adheres the slot inner spacer paper to the slot outer spacer paper.

[0072] When the ultrasonic welding mechanism 6 presses the slot inner spacer paper and the slot outer spacer paper, the slot outer spacer paper is in a straight and tight state at this time, and the cutting of the slot outer spacer paper is completed at this time.

[0073] With reference to Figure 2 and Figure 8 , the traction mechanism 7 comprises a screw rod seat 71, a screw rod assembly 72, a screw rod motor 73, and a clamping assembly 74.
