Description

Technical Field

[0001] This utility model belongs to the field of yarn frame technology, specifically relating to a multi-axis yarn guide frame. Background Technology

[0002] When producing coarse yarn, multiple strands of yarn need to be twisted together. Typically, the yarn bobbin is placed above a doubling machine for unwinding. However, existing doubling machines have limited space on the yarn rack, and the number of guide rods for placing the yarn bobbin is also limited, failing to meet production requirements. To solve this problem, a yarn rack needs to be installed next to the doubling machine. However, traditional yarn racks have an array of guide rods, resulting in a large overall space requirement, high investment costs, and a high rate of idleness after production of specific products, increasing overall production costs. Utility Model Content

[0003] The purpose of this invention is to provide a multi-axis yarn guide frame that provides enough yarn guide rods to hold yarn bobbins to meet the production of coarse yarn while reducing the space occupied by the yarn frame, allowing for flexible use and lowering costs.

[0004] The technical solution adopted by this utility model is a multi-axis yarn guide frame, including a cross-shaped bottom support and a top support. The bottom support has universal wheels at the four ends and a vertical pole at the top. The top support is fixedly connected to the top of the vertical pole. A column is fixedly connected to the center of the bottom support and the top support. The top of the column passes through the top support and is fixedly connected to the top plate. A guide frame is provided on one side of the top plate. The bottom end of the guide frame is fixed to the top support by a support rod. Multiple horizontal bars are longitudinally spaced on each vertical pole. Each horizontal bar has a rotating seat at both ends, and a yarn guide rod is rotatably connected to the rotating seat. Multiple yarn guide holes are opened on the vertical pole, the top plate and the guide frame respectively.

[0005] Furthermore, the upright includes two horizontal plates and two vertical plates, which are vertically connected and each of the horizontal and vertical plates has a yarn guide hole in the longitudinal direction.

[0006] Furthermore, the aforementioned guide frame includes a first guide rod, a second guide rod, a first tension rod, a second tension rod, and a third tension rod. The first guide rod and the second guide rod are spaced apart parallel to the top plate, and multiple yarn guide holes are correspondingly opened on the first guide rod and the second guide rod along their length direction. A mounting plate is connected between the two ends of the first guide rod and the second guide rod. A first strip-shaped hole is longitudinally opened in the center of the mounting plate, and a second strip-shaped hole and a third strip-shaped hole are respectively opened on both sides of the first strip-shaped hole. The two ends of the first tension rod are fastened to the mounting plate with nuts after passing through the first strip-shaped hole. The second tension rod and the third tension rod are fixed to the mounting plate with nuts after passing through the second strip-shaped hole and the third strip-shaped hole, respectively. Support rods are welded to the bottom end faces of the first guide rod and the second guide rod, and a top bracket is welded to the bottom end of the support rod.

[0007] The first and second guide rods are 5-10cm higher than the top plate. The first and second guide rods are made of square steel. The yarn guide holes are opened on the sides of the first and second guide rods. The first, second, and third tension rods are made of smooth round rods. After the yarn passes through the yarn guide hole of the first guide rod, it passes through the third tension rod, the first tension rod, and the second tension rod in sequence and then passes through the yarn guide hole of the second guide rod.

[0008] Furthermore, multiple yarn guide holes are opened along the longitudinal and transverse central axes on the aforementioned top plate.

[0009] Furthermore, the aforementioned yarn guide rod is L-shaped, comprising a short rod and a long rod. The lower part of the short rod extends into the rotating seat and is rotatably connected thereto. The long rod extends horizontally to place the yarn bobbin, and a limiting block is provided at the end of the long rod near the short rod.

[0010] Compared to existing technologies, the advantages of this invention are that the bottom support is designed in a cross shape, with a vertical pole between the bottom and top supports. Multiple horizontal bars are arranged longitudinally on the vertical pole, and rotatable yarn guide rods are installed at both ends of each horizontal bar. This design allows for the placement of multiple yarn bobbins within a limited space, meeting production needs while reducing the footprint of the yarn frame. Furthermore, the rotatable yarn guide rods prevent interference from multiple yarn bobbins, ensuring smooth unwinding and guiding of the yarn to the twisting machine. This yarn guide frame is small, mobile, and flexible, suitable for various product production, has high utilization, and reduces production costs. Attached Figure Description

[0016] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0017] Example 1

[0018] like Figure 1-5As shown, a multi-axis yarn guide frame includes a bottom support 1, a top support 2, a column 3, a vertical rod 4, a crossbar 5, a yarn guide rod 6, a top plate 7, and a guide frame 8. Both the bottom support 1 and the top support 2 are cross-shaped. The bottom support 1 has casters 9 at each of its four ends for easy movement and flexible use. The bottom ends of the vertical rods 4 are welded to the top surfaces of the four ends of the bottom support 1, and the top ends of the vertical rods 4 are welded to the bottom surfaces of the four ends of the top support 2. The column 3 is fixedly connected to the center of the bottom support 1 and the top support 2. The bottom support 1, top support 2, column 3, and vertical rod 4 constitute the main structure of the yarn guide frame, providing good stability and structural strength, and enabling stable support for unwinding multiple yarn bobbins. The top of the column 3 passes through the top bracket 1 and is fixedly connected to the top plate 7. A guide frame 8 is provided on one side of the top plate 7. The bottom end of the guide frame 8 is fixed to the top bracket 1 by a support rod 10. Each column 4 has multiple horizontal bars 5 arranged longitudinally at intervals. Each horizontal bar 5 has a rotating seat 501 at both ends, and a yarn guide rod 6 is rotatably connected to the rotating seat 501. Multiple yarn guide holes 11 are opened on the column 3, the top plate 7 and the guide frame 8 respectively. The yarn bobbin is placed on the yarn guide rod 6. After the yarn passes through the yarn guide hole on the column, it enters the yarn guide hole on the top plate, and then is led out through the yarn guide hole on the guide frame to be pulled to the twisting machine. This not only makes the yarn of each yarn bobbin pulled in an orderly manner, avoiding interference and knotting, but also unifies the yarn inlet direction, which is conducive to constant yarn tension.

[0019] A vertical pole 3 is installed between the bottom support 1 and the top support 2. Multiple horizontal bars 5 are arranged longitudinally on the vertical pole 3. Rotatable yarn guide rods 6 are installed at both ends of each horizontal bar 5. This allows for the placement of multiple yarn bobbins within a limited space, meeting production needs while reducing the footprint of the yarn frame. Furthermore, the rotatable yarn guide rods can be adjusted to avoid interference from multiple yarn bobbins, ensuring smooth unwinding and guiding of the yarn to the twisting machine. This yarn guide frame is compact, mobile, and flexible, suitable for various product production, with high utilization and reduced production costs.

[0020] The aforementioned column 3 includes two horizontal plates 301 and two vertical plates 302. The two horizontal plates 301 and the two vertical plates 302 are vertically connected, and both the horizontal plates 301 and the vertical plates 302 have longitudinally opened yarn guide holes 11 to meet the needs of yarn traction in each direction and height.

[0021] Furthermore, the aforementioned guide frame 8 includes a first guide rod 801, a second guide rod 802, a first tension rod 803, a second tension rod 804, and a third tension rod 805. The first guide rod 801 and the second guide rod 802 are spaced apart parallel to the top plate 7, and multiple yarn guide holes 11 are correspondingly opened on the first guide rod 801 and the second guide rod 802 along the length direction. This facilitates the smooth entry of the yarn passing through the yarn guide holes 11 of the top plate 7 into the yarn guide holes of the guide frame 8, maintaining yarn parallelism and stable tension. A mounting plate 806 connects the two ends of the first tension rod 801 and the second guide rod 802. A first longitudinal slot 8061 is formed in the center of the mounting plate 806. A second transverse slot 8062 and a third transverse slot 8063 are formed on either side of the first slot 8061. The first tension rod 803 passes through the first slot 8061 and is secured to the mounting plate 806 with nuts. The second tension rod 804 and the third tension rod 805 pass through the second slot 8062 and the third slot 8063 respectively and are secured with nuts. Mounted on mounting plate 806, support rods 807 are welded to the bottom surfaces of the first guide rod 801 and the second guide rod 802. A top bracket 2 is welded to the bottom of the support rod 807. The first guide rod 801 and the second guide rod 802 are 5-10cm higher than the top plate. The first guide rod 801 and the second guide rod 802 are made of square steel. Yarn guide holes are opened on the sides of the first guide rod 801 and the second guide rod 802. The first tension rod 803, the second tension rod 804, and the third tension rod 805 are made of smooth round rods. After the yarn passes through the yarn guide hole of the first guide rod 801, it passes through the third tension rod 805, the first tension rod 803, and the second tension rod 804 in sequence, and then passes through the yarn guide hole of the second guide rod 802. The tension of the yarn is balanced by the first tension rod 803, the second tension rod 804, and the third tension rod 805. The tension applied to the yarn is adjusted by changing the relative positions of the first tension rod, the second tension rod, and the third tension rod through the first strip hole, the second strip hole, and the third strip hole.

[0022] To meet the needs of yarn traction in all directions, multiple yarn guide holes are provided on the top plate 7 along the longitudinal and transverse central axes.

[0023] Furthermore, the aforementioned yarn guide rod 6 is L-shaped, including a short rod 601 and a long rod 602. The lower part of the short rod 601 extends into the rotating seat 501 and is rotatably connected to it. The long rod 602 extends horizontally to place the yarn bobbin. A limiting block 603 is provided at the end of the long rod 602 near the short rod 601 to prevent the yarn bobbin from abutting against the crossbar 5 and affecting unwinding.

[0024] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
