Abstract
Description
Technical Field
[0001] This utility model relates to warping machines, and more particularly to a yarn guiding structure for a warping machine. Background Technology
[0002] A warping machine is a device that winds a certain number of yarns parallel to each other onto a warp beam. Warping machines typically have a yarn guide structure before the warp beam, which has multiple guide members for the yarns to pass through. The yarn guide structure guides these yarns, ensuring they are parallel and spaced appropriately. Warping machines generally also have a crank-slider structure to drive the yarn guide structure to move back and forth horizontally in small amplitudes, perpendicular to the yarn. This divides the warp beam surface into several annular areas, each for winding a single strand of yarn. Due to the influence of various factors such as yarn thickness, material, and the subsequent warp-knitted product, the yarn spacing needs to be adjusted during warping. Correspondingly, the spacing of the guide members in the yarn guide structure also needs adjustment; that is, the guide structure also has a pitch-adjusting mechanism to adjust the spacing of the guide members. Existing pitch-adjusting mechanisms in guide structures generally use a scissor-arm design, which is relatively complex and unstable during adjustment. Utility Model Content

[0033] Please see Figure 1 and Figure 4A yarn guiding structure for a warping machine includes: a mounting part 1, two swing bars 2, an adjusting mechanism 3, and multiple sets of yarn guiding units 4.
[0034] The mounting part 1 has guide members 1a on two opposing sides in the longitudinal direction. More specifically, the mounting part 1 can be rectangular, with two inner walls of corresponding lengths facing each other in the longitudinal direction for mounting the guide members 1a. The guide members 1a can be linear guides, guide rods, guide grooves, etc. Correspondingly, the direction of back-and-forth movement guided by the guide members 1a is transverse.
[0035] Please see Figure 3 The two swing bars 2 have their first ends, which are close to each other, hinged to the same first slider 2a. They can be hinged to the same pin or to two staggered pins. The second ends, which are far apart from each other, are each hinged to a second slider 2b. The two second sliders 2b are slidably connected to one of the guide members 1a. Each swing bar 2 also has multiple equally spaced connecting holes 2c. That is, for any swing bar 2, the connecting positions of the first and second ends form a line segment, and the center of each connecting hole 2c lies on this line segment.
[0036] The adjusting mechanism 3 adopts a linear motion mechanism, which acts on the first slider 2a to adjust the position of the first slider 2a relative to the mounting part 1 in the longitudinal direction, that is, to drive the first ends of the two swing bars 2 to move in the longitudinal direction. Obviously, as the first ends of the two swing bars 2 move in the longitudinal direction, the second ends of the two swing bars 2 will move laterally along the guide member 1a, and the two second ends move in opposite directions.
[0037] As the first ends of the two swing bars 2 move longitudinally, although the distance between any two adjacent connecting holes 2c on the swing bar 2 remains constant, the length of the line segment projected onto the horizontal direction by this distance will change accordingly.
[0038] Additionally, attention should be paid to the connecting holes 2c closest to the first end of the two swing bars 2. The distance between these connecting holes 2c and the hinged position at the first end can be designed to be equal to half the distance between any two adjacent connecting holes 2c. In this way, the length of the line segment projected laterally from the distance between these two connecting holes 2c is equal to the length of the line segment projected laterally from the distance between any two adjacent connecting holes 2c on the swing bar 2. That is, for all connecting holes 2c, the length of the line segment projected laterally from the distance between any two adjacent connecting holes 2c is equal.
[0039] Please see Figure 3 and Figure 5 In some embodiments, the adjusting mechanism 3 is a lead screw module, which can be either hand-cranked or motor-driven. That is, the first slider 2a mentioned above is a slider in the lead screw module, which is moved by the rotation of the lead screw.
[0040] The number of yarn guide units 4 is equal to the sum of the number of connecting holes 2c on the two swing bars 2, that is, the yarn guide units 4 are connected to the connecting holes 2c one by one.
[0041] Please see Figure 8 and Figure 9 The yarn guiding unit 4 includes: a connecting strip 41, a connecting sleeve 42, and a first yarn guiding component 43.
[0042] Please see Figure 6 The connecting strip 41 is longitudinal and its two ends are slidably connected to the two guide members 1a respectively.
[0043] Please see Figure 5 and Figure 7 In some embodiments, the guide member 1a is selected as a guide rod, and both ends of the connecting strip 41 have a third slider 41a. The second slider 2b and the third slider 41a both have insertion recesses for matching guide rods. More specifically, the insertion recesses can be Ω-shaped, radially close to the guide rod, and the guide rod can be inserted into the insertion recesses through deformation.
[0044] Compared to the first slider 2a and the third slider 41a being sleeved on the guide rod, the design of the insertion notch eliminates the need to remove the guide rod from the mounting part 1, and the first slider 2a and the third slider 41a can also be removed from the guide rod, making subsequent maintenance and repair more convenient.
[0045] Please see Figure 7 and Figure 9 The connecting sleeve 42 is slidably connected to the connecting strip 41 along the longitudinal direction, and the connecting sleeve 42 is also hinged to the corresponding connecting hole 2c. Obviously, combined with the above statement that "as the first ends of the two swing strips 2 move longitudinally, the second ends of the two swing strips 2 will move laterally along the guide member 1a", the connecting sleeve 42 will move simultaneously in the lateral and longitudinal directions. The lateral movement is achieved by the sliding of the connecting strip 41 relative to the guide member 1a, and the longitudinal movement is achieved by the sliding of the connecting sleeve 42 relative to the connecting strip 41.
[0046] The first yarn guide component 43 is fixedly connected to the connecting sleeve 42. The first yarn guide component 43 can be a pigtail loop, ceramic eye, etc. The multiple strands of yarn of the warping machine pass through the multiple first yarn guide components 43 one by one.
[0047] In summary, when the adjusting mechanism 3 adjusts the position of the first slider 2a relative to the mounting part 1 along the longitudinal direction, the first ends of the two swing bars 2 move longitudinally, and the second ends of the two swing bars 2 move laterally along the guide member 1a. The connecting sleeve 42 moves simultaneously both laterally and longitudinally. During this simultaneous movement of the connecting sleeve 42, the first yarn guide member 43 and the connecting sleeve 42 remain relatively fixed. That is, the first yarn guide member 43 also moves simultaneously both laterally and longitudinally, while maintaining the guidance of the yarn in the longitudinal direction, changing the spacing between adjacent yarns, and ensuring equal spacing between all yarns.
[0048] Please see Figure 9 and Figure 10 In some embodiments, the first yarn guide member 43 includes: a base 431, a base portion 432, and two limiting rods 433. The base 431 is fixedly connected to the connecting sleeve 42. The center position of the base portion 432 is fixedly connected to the base 431, and the base portion 432 can also be adjusted to a fixed position on the base 431 by swinging around the center position. The two limiting rods 433 are fixedly connected to the base portion 432 and are symmetrical about the center of the base portion 432.
[0049] The yarn passes between two limiting rods 433, which limit the yarn's offset range. The two limiting rods 433 project longitudinally onto the guide member 1a to form two projection positions. By adjusting the fixed position of the base 432 on the base 431, the distance between these two projection positions will change, which can easily accommodate yarns of different thicknesses within a certain range.
[0050] More specifically, the base 431 has a threaded rod 431a on its top surface. After the base 432 is fitted onto the threaded rod 431a, a rubber pad 431b is fitted onto it. Finally, a nut 431c is used to press down on the rubber pad 431b and the base 432 for fixation. The tightness of the nut 431c is controlled so that the maximum static friction between the base 432 and the rubber pad 431b is appropriate. The base 432 can be manually rotated by force, while the contact between the yarn and the limiting rod 433 does not affect the relative fixation between the base 432 and the base 431.
[0051] Please see Figure 1 and Figure 2 In some embodiments, the yarn guiding structure of the warping machine further includes a second yarn guiding component 5. The second yarn guiding component 5 is the same as the first yarn guiding component 43, and the second yarn guiding component 5 is mounted on the first slider 2a.
[0052] Accordingly, firstly, the number of yarns in the warping machine is one more than the number of the first yarn guide components 43, and the extra yarn passes through the second yarn guide component 5; secondly, for the connecting hole 2c closest to the first end of the two swing bars 2, the distance between the connecting hole 2c and the hinge position of the first end can be designed to be equal to the distance between two adjacent connecting holes 2c.
[0053] By adding the second yarn guide component 5, the distance between the connecting hole 2c closest to the first end and the hinge position of the first end is increased, making it easier to set the adjustment mechanism 3 and the yarn guide unit 4 on the two connecting holes 2c.
[0054] Please see Figure 8 and Figure 9 In some embodiments, the oscillating bar 2 is located above the connecting sleeve 42, and the first yarn guide member 43 coincides with the fixed connection position of the connecting sleeve 42 and the hinged position of the oscillating bar 2. More specifically, the top surface of the connecting sleeve 42 may have a connecting segment 42a, the lower part of which is smooth for the oscillating bar 2 to be fitted into, and the lower part of which is threaded for the first yarn guide member 43 to be threadedly connected. Correspondingly, if a second yarn guide member 5 is added, the top surface of the first slider 2a also has such a connecting segment 42a.
