Description

Technical Field

[0001] This application relates to the field of textile production equipment technology, and more specifically, to a floor-standing yarn rack for a circular knitting machine. Background Technology

[0002] Floor-standing yarn racks are specialized equipment used in the textile industry to carry, store, and transfer warp yarns (yarn bobbins). They mainly serve textile equipment such as circular knitting machines and warp knitting machines, acting as a "transfer station" for yarn supply.

[0003] The existing yarn rack support frame is mostly a rigid connection or a simple folding design. Its ground contact area and support area are fixed and cannot be adjusted. This causes the yarn rack to be unbalanced at both ends when the warp yarn is loaded due to incomplete loading, resulting in insufficient stability of the yarn rack. During transfer, the fixed width of the yarn rack makes it difficult to pass through narrow channels, resulting in reduced transfer efficiency.

[0004] Therefore, we propose a floor-standing yarn rack for circular knitting machines to solve the existing problems. Utility Model Content

[0010] Preferably, the transmission assembly includes a transmission rod, which is rotatably connected to the main frame, and both ends of the transmission rod pass through the side walls at both ends of the main frame and are connected to a second bevel gear. The two second bevel gears at both ends are respectively engaged with the first bevel gears at the bottom of the corresponding lead screws at both ends.

[0011] Preferably, the support frame has a receiving groove extending along the length of the support frame at one end relative to the main frame, and the receiving groove has a connecting end that is hinged to the adjusting rod.

[0012] Preferably, several groups of first hangers are distributed along the longitudinal direction of the main frame, and several groups of second hangers are distributed along the length direction of the support frame, with the several groups of first hangers and several groups of second hangers being staggered with each other.

[0031] like Figures 1 to 7As shown, a floor-standing yarn rack for a circular knitting machine includes a main frame 1, with movable support frames 2 hinged to both sides of the main frame 1. An adjustment component 3 is located inside the main frame 1 and is adjustablely connected to the support frames 2 on both sides. Universal wheels 22 are located at the bottom of the support frames 2. One end of the adjustment component 3 passes through the main frame 1 and is connected to a drive device 5. Several sets of first hangers 11 are rotatably connected to both sides of the main frame 1, and several sets of second hangers 21 are rotatably connected to the support frames 2 on both sides. In use, the support frames 2 on both sides are hinged to the main frame 1, and the universal wheels 22 at the bottom of the support frames 2 contact the ground for transferring warp yarns. The adjustment component 3 can... The two side support frames 2 are adjusted to be connected. The adjustment component 3 can be driven by the drive device 5 to change the angle between the two side support frames 2 and the main frame 1, thereby changing the support area between the two side support frames 2 and the ground. When loading warp yarn, the support frames 2 at both ends of the main frame 1 are at the maximum opening angle with the main frame 1, so that the main frame 1 has the maximum support area and increases the stability of the main frame 1. During transfer, the opening angle between the two side support frames 2 and the main frame 1 can be flexibly adjusted by the adjustment component 3 so that the support frames 2 and the main frame 1 are kept in a compact state, so that the warp yarn can pass through narrow areas when transferring.

[0032] Furthermore, the adjustment components 3 are provided in two sets, which are respectively set at both ends of the main frame 1. A transmission component 4 is provided between the two sets of adjustment components 3. At least one drive device 5 is provided. The drive device 5 is installed on the outside of one end of the main frame 1 and passes through the main frame 1 to drive the adjustment components 3. In use, the adjustment components 3 set at both ends of the main frame 1 are driven synchronously through the transmission component 4. The two adjustment components 3 are respectively connected to both ends of the support frame 2, so that the support frame 2 is more stable when the angle is adjusted.

[0033] Furthermore, the adjustment component 3 includes a lead screw 31, which is rotatably connected to the main frame 1. A slider 32 is slidably connected to the lead screw 31. The slider 32 has connecting ends on both sides, and adjusting rods 33 are hinged to the connecting ends on both sides respectively. The adjusting rods 33 on both sides are respectively connected to the supporting frames 2 on both sides. By rotating the lead screw 31, the slider 32 is driven to slide relative to the lead screw 31, and then the adjusting rods 33 connected to both sides of the slider 32 drive the supporting frames 2 on both sides to adjust the angle.

[0034] Furthermore, a first bevel gear 34 is provided at one end of the bottom of the lead screw 31. A third bevel gear 51 that meshes with the first bevel gear 34 is provided through the main frame 1 of the drive device 5. A rotating handle 52 that is fixedly connected to the third bevel gear 51 is provided at one end of the drive device 5 located outside the main frame 1. In use, the third bevel gear 51 is driven to rotate by rotating the handle 52. The third bevel gear 51 meshes with the first bevel gear 34 at the bottom of the lead screw 31, thereby driving the lead screw 31 to rotate relative to the main frame 1. This causes the slider 32 provided on the lead screw 31 to slide relative to the lead screw 31, thereby driving the adjusting rod 33 to move.

[0035] Furthermore, the transmission assembly 4 includes a transmission rod 42, which is rotatably connected to the main frame 1. Both ends of the transmission rod 42 pass through the side walls at both ends of the main frame 1 and are connected to second bevel gears 41. The two second bevel gears 41 at both ends are respectively engaged with the first bevel gears 34 at the bottom of the corresponding lead screws 31. In use, the second bevel gears 41 at both ends of the transmission rod 42 are arranged axially symmetrically, so that when the drive device 5 adjusts the opening angle of the support frame 2, the sliders 32 distributed on the lead screws 31 at both ends move in the same direction. The two sets of adjustment assemblies 3 achieve synchronous movement through the transmission rod 42 and the bevel gears, ensuring the symmetry and stability of the angle adjustment of the support frame 2 on both sides and avoiding uneven force on one side.

[0036] Furthermore, the support frame 2 has a receiving groove 24 extending along the length of the support frame 2 at one end relative to the main frame 1. The receiving groove 24 has a connecting end that is hinged to the adjusting rod 33. In use, when the support frame 2 is adjusted to the minimum angle and remains parallel to the main frame 1, the adjusting rod 33 is stored in the receiving groove 24, so that the width between the main frame 1 and the two side support frames 2 is minimized, making it easier to pass through narrow areas.

[0037] Furthermore, several sets of first hangers 11 are distributed longitudinally along the main frame 1, and several sets of second hangers 21 are distributed along the length of the support frame 2. The several sets of first hangers 11 and several sets of second hangers 21 are staggered with each other. In use, the first hangers 11 and second hangers 21 are used to hang warp yarns. The staggered arrangement of the several sets of first hangers 11 and several sets of second hangers 21 avoids interference between the first hangers 11 and second hangers 21 when the warp yarns are hung or the support frame 2 is adjusted.

[0038] Furthermore, a first pull rod assembly 12 connects several groups of first hangers 11, and a second pull rod assembly 23 connects several groups of second hangers 21. In use, the orientation of all first hangers 11 is adjusted synchronously by the first pull rod assembly 12, and the orientation of all second hangers 21 is adjusted synchronously by the second pull rod assembly 23. This allows the first pull rod assembly 12 to drive all first hangers 11 to rotate around their own axis and be placed in a vertical position, and the second pull rod assembly 23 to drive all second hangers 21 to rotate around their own axis and be placed in a vertical position. This further reduces the overall width of the present invention, making it easier to pass through narrow areas.

[0039] Furthermore, the first pull rod assembly 12 includes a plurality of first connecting rods 121 and a first synchronous connecting rod 122. One end of each of the first connecting rods 121 is fixedly connected to a plurality of sets of first hangers 11, and the other ends of each of the first connecting rods 121 are connected through the first synchronous connecting rod 122. The other end of each first synchronous connecting rod 122 is provided with a first handle 123. The side ends of each of the first hangers 11 are provided with a first limiting block 124 and a second limiting block 125, and the first limiting block 124 and the second limiting block 125 are perpendicular to each other. In use, the first limiting block 124 and the second limiting block 125 are used to limit the rotation of the first connecting rod 121. The first limiting block 124 is used to keep the first hanging bracket 11 connected to the first connecting rod 121 horizontal and stop it after rotating to the horizontal position, so as to prevent the first hanging bracket 11 from continuing to rotate and causing the warp yarn to fall. The second limiting block 125 is set longitudinally to prevent the first hanging bracket 11 from continuing to rotate after rotating to be parallel to the main frame 1, which would cause it to collide and interfere with the first hanging bracket 11 on the other side.

[0040] Furthermore, the second pull rod assembly 23 includes several second connecting rods 231 and second synchronous connecting rods 232. Two ends of the several second connecting rods 231 are fixedly connected to several sets of second hangers 21. The other two ends of the several second connecting rods 231 are connected via the second synchronous connecting rods 232. The other end of the second synchronous connecting rods 232 is provided with a second handle 233. The side ends of the several second hangers 21 are each provided with a third limiting block 211 and a fourth limiting block 212. The third limiting block 211 and the fourth limiting block 212 are perpendicular to each other. In use, the third limiting block 211... The first and fourth limiting blocks 212 are used to limit the rotation of the second connecting rod 231. The third limiting block 211 is perpendicular to the end face of the support frame 2, limiting the second hanger 21 connected to the second connecting rod 231 to stop after rotating to a position perpendicular to the end face of the support frame 2, thus preventing the warp yarn from falling off if the second hanger 21 continues to rotate. The fourth limiting block 212 is set parallel to the end face of the support frame 2, thus preventing the second hanger 21 from continuing to rotate after rotating to a position parallel to the support frame 2, thus preventing it from colliding and interfering with the first hanger 11 on the same side.

[0041] In use, the two side support frames 2 are hinged to the main frame 1, and the bottom universal wheels 22 are in contact with the ground for transferring warp yarns. The adjustment component 3 is driven by the drive device 5 to adjust the angle between the two side support frames 2 and the main frame 1, thereby changing the support area between the two side support frames 2 and the ground. When loading warp yarns, the support frames 2 at both ends of the main frame 1 are at the maximum opening angle with the main frame 1, so that the main frame 1 has the maximum support area to increase stability. During transfer, the opening angle between the two side support frames 2 and the main frame 1 can be flexibly adjusted by the adjustment component 3 to facilitate passage through narrow areas. There are two sets of adjustment components 3, located at both ends of the main frame 1 respectively. A transmission component 4 is provided between the two sets of adjustment components 3. At least one drive device 5 is installed on the outside of one end of the main frame 1, passing through the main frame 1 and drivingly connected to the adjustment component 3. In use, the transmission component 4 synchronously drives the adjustment components 3 at both ends of the main frame 1, so that the angle of the support frames 2 located on both sides of the main frame 1 is adjusted synchronously and more stably. The main frame 1 and the support frames 2 are provided with interlocking first hangers 11 and second hangers 21 for hanging warp yarns for transfer.

[0042] The above-described specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
