Description

Technical Field

[0001] The utility model relates to a blade-alternating reciprocating transverse yarn blocking mechanism, belonging to the technical field of spinning equipment. Background Art

[0002] In the field of yarn plying and doubling, the traverse mechanisms of doubling machines that are more commonly used on the market include fork type, pulley paddle type, traverse yarn guide nozzle type and other forms. Among them, the fork type and traverse yarn guide nozzle type are more widely used and popular. The main technical principle is to use a traction yarn guide or yarn hanging device to pull the yarn back and forth along a predetermined trajectory (generally horizontal direction) at high speed. During the movement, the passive or active rotation of the yarn tube is coordinated to form a uniformly arranged ply yarn roll with a certain density on the yarn tube.

[0003] exist Figure 1 In the embodiment, the servo motor 06 is fixed on the mounting plate that needs to have the traverse function, and the servo motor 06 can perform fast forward and reverse rotation switching. The front end of the motor output shaft is installed with a large wheel 03, and the small wheel 04 is installed on the horizontal panel 03. The small wheel 04 can rotate freely. The large wheel 03 and the small wheel 04 are connected by a transmission belt 05. In the transmission belt 05 between the large wheel 03 and the small wheel 04, the upper half remains horizontal with the sliding guide rod 02. The sliding guide rod 02 is installed and fixed above the transmission belt 05 and remains horizontal with the transmission belt 05. The upper half of yarn nozzle 01 has a through-hole that passes through sliding guide rod 02. Yarn nozzle 01 can slide freely horizontally on sliding guide rod 02. The lower half of yarn nozzle 01 has a clamp that can be firmly clamped to the upper half of transmission belt 05. When servo motor 106 drives large wheel 03 and small wheel 04 back and forth via transmission belt 05, the upper half of transmission belt 05 carries yarn nozzle 01 back and forth along sliding guide rod 02. The speed and frequency of yarn nozzle 01's sliding are related to the rotation speed of servo motor 106 and the forward and reverse rotation switching frequency. When yarn strand 19 is hung in the ceramic nozzle of yarn nozzle 01, yarn nozzle 01 can carry yarn strand 19 to form a regular horizontal arrangement on the high-speed rotating winding bobbin 20, and finally, after a period of accumulation, a large yarn roll is formed.

[0004] The following questions still exist regarding the above content:

[0005] 1) For ordinary doubling machines, the reciprocating speed of the yarn guide type traverse mechanism is limited. In addition, the high-frequency back-and-forth traverse requires high weight and rigidity of the servo motor and the yarn guide itself. The general manufacturing cost and process requirements are not low. In addition, the traverse sliding guide rod needs to be aligned and leveled, which is time-consuming and labor-intensive.

[0006] 2) The yarn guide type traverse mechanism realizes the reciprocating dragging motion of the yarn guide through the high-frequency forward and reverse rotation of the motor. The transmission belt (rope) will wear out very quickly. In actual application, the service life is generally short and the maintenance cost is also high.

[0007] 3) Since the principle of this common mechanism is to drag the yarn back and forth, the faster the motor rotates, the greater the inertia of the yarn guide's lateral movement, resulting in greater vibration and noise, and more severe wear. Utility Model Content

[0008] In view of the problems existing in the above-mentioned prior art, the present invention provides a blade-alternating reciprocating transverse yarn blocking mechanism, thereby solving the above-mentioned technical problems.

[0009] In order to achieve the above-mentioned object, the technical solution adopted by the utility model is as follows: a blade alternating reciprocating traverse yarn blocking mechanism, comprising a servo motor; a transition flange is connected to one side of the servo motor; a coupling is arranged in the transition flange; one end of the coupling is connected to the output shaft of the servo motor, and the other end thereof is connected to the main transmission shaft disc;

[0010] An upper paddle is installed on the top of the main transmission shaft disc; a bearing A is provided on the intermediate shaft of the main transmission shaft disc; the outer ring of the bearing A is sleeved with the main transmission gear; one side of the main transmission gear is meshedly connected to the auxiliary transmission pinion shaft; the lower half of the auxiliary transmission pinion shaft is meshedly connected to the inner gear ring; the inner gear ring is embedded in the flange ring; the upper end of the flange ring is connected to the lower paddle;

[0011] It also includes an intermediate support seat; the inner cavity of the intermediate support seat is provided with a large stepped blind hole and two small through holes on the left and right; a bearing C is installed in the large stepped blind hole; the outer ring of the bearing C is pressed into the inner wall of the large stepped blind hole and fixed, and its inner ring can rotate freely; the two small through holes on the left and right are used for the tail of the main transmission shaft disc and the tail of the auxiliary transmission pinion shaft to pass through; a bearing B is pre-embedded in the small dragon on the right side of the auxiliary transmission pinion shaft; the tail of the auxiliary transmission pinion shaft passes through the inner ring of the bearing B; the outer ring of the bearing B is pressed into the small through hole on the right side of the bottom of the intermediate support seat and the outer ring is fixed;

[0012] The upper end of the middle support seat is provided with an installation step for the yarn blocking piece.

[0013] Furthermore, limiting ears are fixed on both sides of the back side of the arc-shaped yarn blocking piece.

[0014] Furthermore, there is a safety gap between the lower paddle and the yarn blocking piece.

[0015] Furthermore, the yarn blocking piece is an overall arc-shaped structure.

[0016] A staggered assembly gap is left between the upper paddles.

[0017] The beneficial effects of the utility model are as follows: the forward and reverse paddle traversing mechanism of the present structure adopts a direct drive mode of the motor-driven gear, the gear group transmits power to the paddle group, and then the forward and reverse rotation of the paddle group paddles the yarn to be processed on the edge of the yarn blocking piece back and forth within the specified area, and finally cooperates with the high-speed winding bobbin to wind the plied yarn onto the bobbin in different arrangements.

[0018] 1. The mechanical paddle traverse mechanism has good stability. Since most of the gears and bearings are made of steel, they are more durable than ceramic bonded yarn guide mechanisms and fork mechanisms. Since the maintenance-free period of direct-drive gears is much longer than that of transmission belts (ropes), the service life of the key core components of the newly invented invention is more than 5 times that of ordinary yarn guide mechanisms.

[0019] 2. Since the newly invented mechanism uses direct transmission of the motor gear, there is no need to switch the motor forward and reverse. This new paddle-type traverse mechanism can achieve a maximum reciprocating speed of 36 times / second, which is 1.4 times that of the ordinary traverse mechanism.

[0020] 3. The structural design of the new invention mechanism is very compact, and all the parts are assembled into an integrated module, which can be put into use directly after installation and fixation. Therefore, it is more convenient in equipment debugging, saving the leveling and calibration time of the traverse mechanism, and improving the convenience of practical application and maintenance.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] like Figure 2-Figure 4 As shown, a blade alternating reciprocating traverse yarn blocking mechanism includes a servo motor 16; a transition flange 15 is connected to one side of the servo motor 16; a coupling 14 is provided in the transition flange 15; one end of the coupling 14 is connected to the output shaft of the servo motor 16, and the other end thereof is connected to the main transmission shaft disc 2;

[0033] An upper paddle 1 is mounted on the top of the main transmission shaft disc 2; a bearing A4 is provided on the intermediate shaft of the main transmission shaft disc 2; a main transmission gear 7 is sleeved on the outer ring of the bearing A4; a secondary transmission pinion shaft 8 is meshedly connected to one side of the main transmission gear 7; the lower half of the secondary transmission pinion shaft 8 is meshedly connected to the inner gear ring 6; the inner gear ring 6 is embedded in the flange ring 5; the upper end of the flange ring 5 is connected to the lower paddle 3;

[0034] It also includes an intermediate support seat 12; the inner cavity of the intermediate support seat 12 is provided with a large stepped blind hole and two small through holes on the left and right; a bearing C10 is installed in the large stepped blind hole; the outer ring of the bearing C10 is pressed into the inner wall of the large stepped blind hole and fixed, and its inner ring can rotate freely; the two small through holes on the left and right are used for the tail of the main transmission shaft disc 2 and the tail of the auxiliary transmission pinion shaft 8 to pass through; a bearing B9 is pre-embedded in the small dragon on the right side of the auxiliary transmission pinion shaft 8; the tail of the auxiliary transmission pinion shaft 8 passes through the inner ring of the bearing B9; the outer ring of the bearing B9 is pressed into the small through hole on the right side of the bottom of the intermediate support seat 12 and the outer ring is fixed;

[0035] The upper end of the intermediate support seat 12 is provided with a mounting step for the yarn blocking piece 11 .

[0036] In this embodiment, limiting ears 13 are fixed on both sides of the back side of the yarn blocking piece 11.

[0037] In this embodiment, there is a safety gap between the lower paddle 3 and the yarn blocking piece 11.

[0038] In this embodiment, the yarn blocking piece 11 is an overall arc-shaped structure.

[0039] In this embodiment, a staggered assembly gap is left between the upper paddles 1 and the upper paddles 1 .

[0040] This forward and reverse paddle traverse mechanism adopts a direct drive mode of the motor driving the gear. The gear group transmits the power to the paddle group, and then the forward and reverse rotation of the paddle group moves the yarn to be processed on the edge of the yarn blocking piece back and forth within the specified area. Finally, the high-speed winding bobbin is used to wind the plied yarn onto the bobbin in different arrangements.

[0041] Continue to refer to Figure 2The working principle is as follows: the output shaft end 16 of the servo motor is connected to the main transmission shaft disc 2, the top of the main transmission shaft disc 2 is installed with an upper paddle 1, and the middle of the main transmission shaft disc 2 is installed with a main transmission gear 7. When the servo motor 16 rotates in the opposite direction, it drives the main transmission gear 7 and the upper paddle 1 installed on the main transmission shaft disc 2 to rotate together, and the secondary transmission pinion shaft 8 forms a gear meshing with the main transmission gear 7, and the inner gear ring 6 and the lower half of the secondary transmission pinion shaft 8 form an inner gear ring meshing. The inner gear ring 6 is embedded in the flange ring with the lower paddle 3. The lower paddle 3 is installed on the surface of the flange ring 5 and fixed through the hole, so that the rotation of the inner gear ring 6 can drive the entire flange ring 5 and the lower paddle 3 to rotate together; the upper paddle 1 and the lower paddle 3 are installed at staggered levels. According to the principle of gear meshing, the main transmission gear 7 transmits torque to the secondary transmission pinion shaft 8. The transmission pinion shaft 8 and the sub-transmission pinion shaft 8 are transmitted to the inner gear ring 6, thereby realizing the final counterclockwise rotation of the upper paddle 1 and the synchronous clockwise rotation of the lower paddle 3; the upper paddle 1 shifts the yarn from the left side of the A end along the outer arc trajectory of the yarn stop 11 to the right side of the B end and then falls off, and the lower paddle 3 takes over the yarn of the upper paddle 1 and shifts the yarn stop 11 from the right side to the left side, and this back and forth cycle forms a left and right lateral movement trajectory of the yarn. Under the continuous winding action of the winding tube 20, the back and forth lateral movement trajectory of the yarn 19 forms a uniform arrangement on the surface of the winding tube 20, and the winding tube 20 is continuously wound for a period of time to form a finished yarn roll.

[0042] Continue to refer to Figure 3 and Figure 4The servo motor 16 is at the very bottom, with a transition flange 15 connected to the front end of the motor. One end of the coupling 14 is connected to the motor's output shaft, and the other end is connected to the bottom of the main drive shaft disc 2. This allows the servo motor 16 to drive the coupling 14 and the main drive shaft disc 2 to rotate together when it rotates. The inner cavity of the intermediate support seat 12 has a large stepped blind hole and two small through-holes (one on the left and one on the right). Bearing C10 is installed in the large stepped blind hole. The outer ring of bearing C10 is pressed into the inner wall of the large blind hole of the intermediate support seat 12 and fixed. The inner ring of bearing C10 is free to rotate. The two small through-holes allow the rear end of the main drive shaft disc 2 and the rear end of the auxiliary drive pinion shaft 8 to pass through. Bearing B9 is pre-embedded in the small hole on the right side of the mounting end of the auxiliary drive pinion shaft 8. The rear end of the auxiliary drive pinion shaft 8 penetrates the inner ring of bearing B9. The outer ring of bearing B9 is pressed into the small through-hole on the right side of the bottom of the intermediate support seat 12 and fixed. The auxiliary drive pinion shaft 8 and the inner ring of bearing B9 form a new freely rotating body. There is an installation step for the yarn block 11 (arc-shaped) on the front of the middle support seat 12, and the yarn block 11 is fixed on the step surface; the limiting ears 13 are fixed on both sides of the back of the yarn block 11 to prevent the yarn sliding on the yarn block 11 from sliding out of the limit position. There are upper and lower safety gaps between the upper and lower picks 1, the lower pick 3 and the yarn block 11. The inner gear ring 6 is embedded in the flange ring 5. The flange ring 5 and the inner gear ring 6 are installed as a whole into the inner ring of the bearing C10. The lower pick 3 is installed on the upper part of the flange ring 5. Turning the inner gear ring 6 can drive the flange ring 5 and the lower pick 3 to rotate with the inner ring of the bearing C10. The upper paddle 1 is fixed to the surface of the main transmission shaft disc 2. There is a staggered assembly gap between the upper paddle 1 and the lower paddle 3 so that they do not interfere with each other. The bearing A4 is pressed into the middle shaft of the main transmission shaft disc 2. The outer ring of the bearing A4 is covered with the main transmission gear 7. The inner gear ring 6 and the main transmission gear 7 are not coaxial, and the bearing surfaces are staggered up and down. The inner gear ring 6 is on the upper layer, and the main transmission gear 7 is on the lower layer. The bottom shaft of the main transmission shaft disc 2 passes through the left through hole of the middle support seat 12 and is inserted into the coupling 14. At this time, the bearing A4, the main transmission gear 7 and the upper paddle 1 are fixed to the main transmission shaft disc 2.

[0043] When the servo motor 16 transmits power to the main transmission shaft 2, the main transmission shaft 2 rotates together with the main transmission gear 7 and the upper paddle 1. Since the main transmission gear 7 and the auxiliary transmission pinion shaft 8 are in a gear meshing relationship, the auxiliary transmission pinion shaft 8 is driven to rotate together while transmitting torque. Since the shaft end of the auxiliary transmission pinion shaft 8 is in a meshing relationship with the internal gear ring 6, the auxiliary transmission pinion shaft 8 transmits torque and rotation to the internal gear ring 6, and the internal gear ring 6 rotates in the opposite direction with the flange ring 5 and the lower paddle 3 in the intermediate support seat 12.

[0044] Implementation principle description:

[0045] Reference Figure 5In the principle diagram of the paddle guiding the yarn to move horizontally, after the servo motor 16 is energized, it drives the main transmission gear 7 and the upper paddle 1 fixedly associated with it to rotate counterclockwise, with the rotation center point M; the auxiliary transmission pinion shaft 8 engaged with the main transmission gear 7 rotates in the opposite direction (clockwise) under the drive of the main transmission gear 7, and at the same time, the internal gear ring 6 of the auxiliary transmission pinion shaft 8 rotates in the same direction (clockwise) under the drive of the auxiliary transmission pinion shaft 8, and is fixedly associated with the internal gear ring 6. The connected lower paddle 3 rotates counterclockwise following the inner gear ring 6, with the rotation center point being Q. When the yarn 19 is placed on the arc-shaped edge of the yarn blocking piece 11, the end of the upper paddle 1 exceeds the edge of the yarn blocking piece 11, and the yarn 19 is quickly moved to position C, corresponding to the winding trajectory position D on the winding bobbin yarn 20. It is assumed that position C is a position before the yarn 19 is about to leave the edge of the upper paddle 1; at this position, the yarn 19 is only affected by the right-moving action of the upper paddle 1, and has not yet been affected by the lower paddle 3.

[0046] Reference Figure 6 In the principle diagram of the paddle guiding the yarn to move horizontally, when Figure 5 The lateral movement continues, and the upper and lower paddles continue to rotate. The upper paddle 1 moves the yarn 19 to the E position (the limit position of the right lateral movement). At this time, the end of the upper paddle 1 just exits the edge of the yarn blocking piece 11, and the yarn 19 is separated from the end of the upper paddle 1 and is no longer affected by the upper paddle 1. The lower paddle 3 just catches the yarn 19 at the E position and begins to prepare to move the yarn to the left. Assume that the E position is the limit position where the yarn 19 has been separated from the action of the paddle. At this position, the yarn 19 has just escaped the control of the upper paddle 1 and is ready to be controlled by the lower paddle 3. The corresponding trajectory of the winding bobbin 20 is the farthest position of the yarn trajectory at the right end, also known as the right limit position of the maximum motion range.

[0047] Reference Figure 7 In the principle diagram of the paddle guiding the yarn to move horizontally, when Figure 6 Continue to rotate the upper paddle 1 and the lower paddle 3 in the following steps. Figure 6 and 7 In the rotation trajectory of the pick in the figure, the end of the upper pick 1 has been rotated counterclockwise and retracted into the arc edge of the yarn stop 11, and no longer acts on the yarn 19. At this time, the lower pick 3 exceeds the end of the yarn stop 11 to receive the yarn 19 at point E, and uses the lower pick 3 to rotate clockwise on the yarn stop 11 to generate a left-moving force on the yarn 19, moving the yarn 19 and continuing to move it to the left along the yarn stop 11. When the yarn 19 moves to point G along the arc edge of the yarn stop 11, the corresponding arrangement instantaneous trajectory position of point G on the winding yarn 20 is H.

[0048] Reference Figure 8 In the principle diagram of the paddle guiding the yarn to move horizontally, when Figure 7Continue to rotate the upper paddle 1 and the lower paddle 3 in the following steps. Figure 7 and Figure 8 The paddle rotates along the trajectory of the paddle, and the lower paddle 3 continuously paddles the yarn 19 to the left along the yarn stop 11. Similar to the principle of paddles being paddled from the left to the right extreme position, the yarn 19 is paddled to the left extreme position J by the lower paddle 03. At this time, the instantaneous winding trajectory position on the bobbin is K; the trajectory corresponding to the winding bobbin 20 is the farthest position of the yarn trajectory at the left end, also known as the maximum range left extreme position. At this time, the lower paddle 3 gradually rotates and retracts into the yarn stop 11, and the left paddle force acting on the yarn 19 is gradually withdrawn, and the right paddle force of the upper paddle 1 begins to take over; this is repeated; eventually, through the continuous rotation and paddle movement of the upper paddle 1 and the lower paddle 3, the yarn paddle 19 is formed to circulate back and forth on the yarn stop 11, and then continuously and synchronously wound by the winding bobbin 20, finally forming a neatly arranged finished yarn roll.

[0049] The paddle traversing mechanism of this device has good stability. Since the transmission mechanism design cleverly avoids the problem of overheating of the traditional mechanism motor due to long-term forward and reverse rotation, and the actual problem that the transmission belt or transmission rope often breaks, this invention has a longer service life and lower maintenance costs than ordinary traversing mechanisms. The positioning adjustment of the horizontal traversing guide rod of the ordinary traversing mechanism during installation is reduced. The industrial product of this invention can directly install and position the entire component, saving time and effort. The maximum limit traversing speed is fast, the transmission efficiency is better than that of ordinary traversing mechanisms, and the yarn winding output per unit time is higher than that of ordinary ones.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
