Description

Technical Field

[0001] This utility model relates to yarn racks, and more particularly to a yarn hanging rack. Background Technology

[0002] Yarn racks are generally used in conjunction with various textile equipment to install yarn bobbins and guide the yarn from the bobbins into the corresponding textile equipment. A yarn hanger is also a type of yarn rack; the position for installing the yarn bobbins is a hanging rod, which is inclined. After the yarn bobbin is fitted onto the hanging rod, the hanging rod supports the inner wall of the yarn bobbin, and under the action of gravity, the inner end face of the yarn bobbin abuts against a stop block on the hanging rod. Yarn hangers used with textile equipment such as warping machines and circular knitting machines generally have multiple installation areas, each requiring multiple yarn bobbins to be hung. Each installation area includes a front installation strip and a rear installation strip. The hanging rod is located on the rear installation strip, and the corresponding position on the front installation strip has a yarn guide component. When changing yarn bobbins, the hanging rod is located behind the yarn guide component, requiring manual extension to reach the yarn bobbin, which is convenient. However, the large number of yarn bobbins on the entire yarn hanger means that during the yarn bobbin replacement operation, it is easy to come into contact with surrounding yarn, affecting it.

[0038] Please see Figure 1 , Figure 2 and Figure 4 A yarn hanging frame includes a frame body 1 and multiple yarn hanging units 2.

[0039] The frame 1 is constructed from multiple vertical and horizontal pipes. The frame 1 has multiple installation areas 1a from bottom to top, and each installation area 1a includes a front installation strip 1a1 and a rear installation strip 1a2. That is, when constructing the frame 1, an appropriate number of horizontal pipes are used according to the number of layers in the installation area 1a, so that the horizontal pipes at the corresponding positions serve as the front installation strip 1a1 and the rear installation strip 1a2.

[0040] Multiple yarn hanging units 2 are grouped, with the number of groups being the same as the number of installation areas 1a, and are respectively set in the corresponding installation areas 1a. That is, several yarn hanging units 2 in the same group are set in the same installation area 1a in a left-right direction. For any two adjacent installation areas 1a, the yarn hanging units 2 are staggered vertically, that is, in the top or bottom view direction, the yarn hanging units 2 of these two installation areas 1a are interlaced.

[0041] Taking the attached diagram as an example, the installation area 1a has four layers, and each layer of installation area 1a has four yarn hanging units 2. In a top or bottom view, there are eight rows of yarn hanging units 2, with two yarn hanging units 2 in each row. Correspondingly, an L-shaped piece is fixed to the top of the frame 1 for each row of yarn hanging units 2. The horizontal portion of the L-shaped piece has multiple first yarn holes 1b, the number of which is the same as the number of yarn hanging units 2 in a corresponding row, arranged along the front-to-back direction. The top of the frame 1 also has multiple second yarn holes 1c, the number of which is the same as the total number of yarn hanging units 2, arranged along the left-to-right direction. The yarn of any yarn hanging unit 2 first passes through the first yarn hole 1b of the corresponding L-shaped piece, and then through the nearby second yarn hole 1c, ensuring that the yarns of all yarn hanging units 2 are well staggered and do not contact or interfere with each other.

[0042] For any yarn hanging unit 2, the front mounting strip 1a1 provides a yarn guiding position and a yarn changing position, and the rear mounting strip 1a2 provides a yarn hanging position aligned with the yarn guiding position.

[0043] Please see Figure 2 , Figure 3 and Figure 5 A yarn hanging unit 2 includes: a guide component 3, a yarn guiding component 4, a yarn hanging component 5, and a connecting component 6.

[0044] The guide component 3 connects the yarn changing position and the yarn hanging position. More specifically, the guide component 3 can be a connecting strip, which is fixedly connected at both ends to the yarn changing position of the front mounting strip 1a1 and the yarn hanging position of the rear mounting strip 1a2, respectively, using screws. Accordingly, the guide component 3 is inclined in the top or bottom view direction.

[0045] Please see Figure 4 In some embodiments, the guide member 3 has the same orientation for any one mounting area 1a; and the guide member 3 has opposite orientations for any two adjacent mounting areas 1a.

[0046] This allows for more efficient use of the space in the left and right directions of frame 1, making the dimensions of frame 1 more compact in the left and right directions.

[0047] Please see Figure 1 and Figure 7 The yarn guide component 4 is located at the yarn guiding position. The yarn guide component 4 can be a pigtail loop, a ceramic eye, etc. More specifically, the yarn guide component 4 can be two ceramic eyes, and a housing 4a is fixedly connected to the yarn guiding position. The housing 4a has a channel for the yarn to pass through. The channel is inclined, and the two ceramic eyes are respectively installed at the inlet and outlet of the channel.

[0048] Please see Figure 3The yarn hanging component 5 is slidably connected to the guide component 3, meaning that the yarn hanging component 5 moves back and forth between the yarn changing position of the front mounting strip 1a1 and the yarn hanging position of the rear mounting strip 1a2. The yarn hanging component 5 is used for hanging the yarn supply tube, meaning that the yarn hanging component 5 needs to have a yarn hanging rod into which the yarn supply tube is inserted.

[0049] The connecting member 6 is disposed on the yarn hanging member 5 or at the yarn hanging position. The connecting member 6 is used to restrict the yarn hanging member 5 at the yarn hanging position, and this restriction can be released.

[0050] In some embodiments, the connecting member 6 may be a magnet, installed at the yarn hanging position, for magnetically attracting the yarn hanging member 5.

[0051] Please see Figure 3 and Figure 5 In some embodiments, the yarn-hanging component 5 includes: a sliding portion 51, a yarn-hanging portion 52, and a first elastic element 53. The connecting component 6 is a rear limiting hook fixedly connected to the yarn-hanging portion 52.

[0052] The sliding part 51 is used to slide and connect with the guide member 3. More specifically, the sliding part 51 includes a sliding sleeve 511 slidably connected to the guide member 3 and a base 512 fixedly connected to the sliding sleeve 511. The sliding sleeve 511 slides, and the front end face and rear end face of the base 512 are used to abut against the front mounting strip 1a1 and the rear mounting strip 1a2 respectively during the sliding process, so as to realize the positioning of the sliding part 51 at the yarn changing position and the yarn hanging position.

[0053] The yarn hanging part 52 is hinged to the sliding part 51, that is, the yarn hanging part 52 includes: a hinge block 521 and a yarn hanging rod 522 fixed to the hinge block 521.

[0054] The first elastic element 53 is disposed between the sliding portion 51 and the yarn hanging portion 52. The first elastic element 53 keeps the rear limit hook in a limited state that restricts the yarn hanging member 5 to the yarn hanging position.

[0055] More specifically, the first elastic element 53 is a torsion spring. Under the action of the torsion spring, the hinge block 521 of the yarn hanging part 52 presses downward against the sliding part 51. The frame 1 is fixed with a left-right oriented rod 1d for each rear mounting strip 1a2, and the rod 1d is above the corresponding rear mounting strip 1a2. By manually overcoming the first elastic element 53, the yarn hanging part 52 and the rear limit hook swing, and the sliding part 51 moves to the yarn hanging position. Under the action of the first elastic element 53, the yarn hanging part 52 and the rear limit hook reset, and the rear limit hook hooks the rod 1d, restricting the yarn hanging component 5 to the yarn hanging position.

[0056] When the yarn bobbin is in normal use, the yarn hanging component 5 is in the yarn hanging position of the rear mounting strip 1a2, and the yarn hanging component 5 is restricted to the yarn hanging position by the connecting component 6. The yarn is drawn out from the yarn bobbin and passes through the yarn guide component 4. When the yarn on a yarn bobbin is about to run out: first, release the restriction of the yarn hanging component 5 by the connecting component 6, and move the yarn bobbin and the yarn hanging component 5 together to the yarn changing position of the front mounting strip 1a1; then disconnect the yarn between the yarn guide component 4 and the yarn bobbin; then remove the yarn bobbin from the yarn hanging component 5; then hang the new yarn bobbin on the yarn hanging component 5, and connect the end of the new yarn bobbin to the yarn break left on the yarn guide component 4; finally, move the new yarn bobbin and the yarn hanging component 5 together to the yarn hanging position of the rear mounting strip 1a2, and the connecting component 6 restricts the yarn hanging component 5 to the yarn hanging position again.

[0057] Please see Figure 6 In some embodiments, in conjunction with the above-described embodiment where "the yarn hanging component 5 includes: a sliding portion 51, a yarn hanging portion 52, and a first elastic member 53", the yarn hanging portion 52 is further fixedly connected to a front limiting hook 521a. The first elastic member 53 keeps the front limiting hook 521a in a limiting state that restricts the yarn hanging component 5 to the yarn changing position.

[0058] Release the restriction of the connecting member 6 on the yarn hanging member 5, and move the yarn tube and the yarn hanging member 5 together to the yarn changing position of the front mounting strip 1a1. Then, the yarn hanging part 52 and the front limit hook 521a are reset under the action of the first elastic member 53. The front limit hook 521a hooks the front mounting strip 1a1 and restricts the yarn hanging member 5 to the yarn changing position.

[0059] In this way, during subsequent operations such as "disconnecting the yarn between the yarn guide component 4 and the yarn bobbin", "removing the yarn bobbin from the yarn hanging component 5", "hanging the new yarn bobbin on the yarn hanging component 5", and "connecting the thread end of the new yarn bobbin with the broken yarn end left on the yarn guide component 4", the yarn hanging component 5 is restricted to the yarn changing position, making the operation more convenient.

[0060] In some embodiments, the yarn hanging unit 2 further includes a yarn pressing rod 7 telescopically connected to the yarn guide position. More specifically, the yarn pressing rod 7 is threadedly connected to the front mounting strip 1a1, and the yarn pressing rod 7 is rotated to extend or retract. The yarn pressing rod 7 presses down the yarn near the yarn guide member 4, ensuring that a yarn break is left on the yarn guide member 4, which facilitates connecting the yarn end drawn from the new yarn bobbin to the yarn break left on the yarn guide member 4.

[0061] In conjunction with the above-mentioned setting that "the yarn guide component 4 can adopt two ceramic eyes", the pressure bar 7 acts on the yarn between the two ceramic eyes.

[0062] Please see Figure 7In some embodiments, the yarn-hanging unit 2 further includes a second elastic element 8 that keeps the yarn-pressing rod 7 in a loose state. The yarn-pressing rod 7 has a threaded section 7a, which is used to thread it with the front mounting strip 1a1 to keep the yarn-pressing rod 7 in a pressed state.

[0063] More specifically, the front mounting strip 1a1 has a mounting hole at the yarn guide position, through which a stepped connecting sleeve 1e passes. The second elastic element 8 is a compression spring, sleeved on the yarn pressing rod 7. The yarn pressing rod 7 passes through the connecting sleeve 1e from below, and a pressure head 7b is fixedly connected to its top end. A threaded section 7a is located near the lower end of the yarn pressing rod 7, and the lower part of the connecting sleeve 1e has a matching internal thread. Under the action of the second elastic element 8, the pressure head 7b presses downward against the top end of the connecting sleeve 1e, at which point the threaded section 7a separates from the connecting sleeve 1e. The upper part of the connecting sleeve 1e has a smaller outer diameter and external threads. The housing 4a is threadedly connected to the upper part of the connecting sleeve 1e, thereby fixing it to the front mounting strip 1a1.

[0064] When it is necessary to press down the yarn, overcome the second elastic element 8 and manually move the pressing rod 7 upward so that the threaded section 7a contacts the internal thread. Rotate the pressing rod 7 so that the threaded section 7a is screwed into the internal thread until the pressing head 7b presses down on the yarn.
