Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn tube positioning clamp technology, specifically a yarn tube positioning clamp for textile machines. Background Technology
[0002] In the textile production process, the yarn bobbin, as the core component carrying the yarn, directly affects the quality and efficiency of yarn winding or unwinding due to its positioning stability on the textile machine. Yarn bobbin positioning clamps are key devices for reliably fixing the yarn bobbin and are widely used in various textile equipment such as winding machines and doubling machines. These clamps are typically installed on the spindles or related actuators of the textile machine. By clamping one or both ends of the yarn bobbin, they ensure that the yarn bobbin maintains coaxiality during high-speed rotation, preventing problems such as uneven yarn tension and yarn breakage caused by misalignment or loosening. They are a fundamental component ensuring continuous textile production. However, with the improvement of automation level and the acceleration of production pace in the textile industry, traditional yarn tube positioning clamps have gradually revealed obvious defects. In the yarn tube switching operation, they often rely on manual adjustment of the mechanical structure to complete the clamping action. Not only is the operation process cumbersome and requires a lot of time for positioning and locking, resulting in a long downtime, but the consistency of manual operation is also poor. Improper control of clamping force can affect the quality of subsequent production, which seriously restricts the overall efficiency improvement of textile production lines and makes it difficult to meet the actual needs of modern textile production for rapid tube changing and efficient operation.
[0003] Therefore, this utility model provides a yarn tube positioning clamp for textile machines. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 A yarn tube positioning clamp for a textile machine includes a support sleeve 1 and a yarn tube 2. A top rod 3 is installed at the top of the support sleeve 1. Several side slots 31 are opened on the outer side of the top rod 3. A swing stop rod 32 is rotatably connected to the inner wall of each of the side slots 31. A lifting push plate 4 is slidably connected to the outer side of the support sleeve 1. The yarn tube 2 is clamped between the lifting push plate 4 and the swing stop rod 32. A base plate 11 is installed at the bottom of the support sleeve 1. A compression spring 42 is installed at the bottom of the lifting push plate 4. The compression spring 42 is installed at the top of the base plate 11 and is sleeved on the outer side of the support sleeve 1.
[0023] It should be noted that a torsion spring is installed between the swing stop bar 32 and the inner wall of the side slot 31 described in this embodiment, and the torsion spring drives the swing stop bar 32 to flip upward.
[0024] Specifically, the yarn tube 2 is inserted downwards from the top of the top rod 3. The inner wall of the yarn tube 2 contacts and presses the outer end of the swing stop rod 32, causing the swing stop rod 32 to rotate around its connecting shaft with the inner wall of the side slot 31 in conjunction with the torsion spring and completely retract into the cavity of the side slot 31. At this time, the yarn tube 2 can smoothly slide down along the outside of the top rod 3 to the outer area of the support sleeve 1. When the bottom end of the yarn tube 2 contacts the upper end face of the lifting push plate 4, the continuous lowering of the yarn tube 2 will press the lifting push plate 4 to slide downwards along the outside of the support sleeve 1. At the same time, the compression spring 42 is compressed by the lifting push plate 4 between the upper end face of the base plate 11 and the lower end face of the lifting push plate 4. During this process, the swing stop rod 32 is no longer compressed by the yarn tube 2, and its restoring elastic force of the torsion spring... Under the action of the side slot 31, the yarn tube 2 is flipped outward until the outer end of the swing stop 32 extends out of the side slot 31 and returns to the initial tilted state. Then, the force applied to the lowering of the yarn tube 2 is stopped, and the lifting push plate 4 slides upward along the support sleeve 1 under the rebound force of the compression spring 42, driving the yarn tube 2 to move upward synchronously until the top surface of the yarn tube 2 contacts the lower surface of the reset swing stop 32. Finally, the yarn tube 2 is clamped between the upper surface of the lifting push plate 4 and the lower surface of the swing stop 32. When disassembling the yarn tube 2, the lifting push plate 4 is pressed down to compress the spring 42 again and drive the yarn tube 2 to move downward. At this time, the top surface of the yarn tube 2 is separated from the lower surface of the swing stop 32. The swing stop 32 is retracted into the side slot 31 and the yarn tube 2 is lifted upward to be taken out.
[0025] In one embodiment of this utility model, such as Figures 1-5 As shown, the top of the lifting push plate 4 is equipped with several limit strips 41, and the bottom of the yarn tube 2 is provided with several limit slots 21. The limit strips 41 are engaged and connected to the inner wall of the corresponding limit slots 21.
[0026] Specifically, when the yarn tube 2 is lowered to the outside of the support sleeve 1 and the lifting push plate 4 is pressed down, the limiting strip 41 at the top of the lifting push plate 4 will be embedded into the inner wall of the limiting groove 21 at the bottom of the yarn tube 2. When the lifting push plate 4 slides up under the action of the compression spring 42, the engaging structure of the limiting strip 41 and the limiting groove 21 will simultaneously restrict the circumferential rotation of the yarn tube 2. At the same time, in conjunction with the axial clamping of the swing stop 32, the yarn tube 2 is fixed in both the axial and circumferential directions on the outside of the support sleeve 1.
[0027] In one embodiment of this utility model, such as Figures 1-5 As shown, a mounting plate 12 is rotatably connected to the bottom of the base plate 11, and a lower extension rod 13 is installed at the bottom of the base plate 11. The lower extension rod 13 passes through the bottom of the mounting plate 12, and a transmission gear 131 is installed at the bottom of the lower extension rod 13.
[0028] Specifically, the mounting plate 12 provides a stable mounting reference for the entire fixture and is connected to the spindle or frame of the textile machine by bolts or other fixing methods to ensure that the fixture does not shift during operation. The lower extension rod 13 at the bottom of the base plate 11 passes through the mounting plate 12, and the transmission gear 131 installed at its bottom meshes with the power output gear or transmission chain of the textile machine. When the textile machine starts, the power is transmitted to the lower extension rod 13 through the transmission gear 131, which in turn drives the base plate 11 and the support sleeve 1, top rod 3, lifting push plate 4 and yarn tube 2 connected to the base plate 11 to rotate synchronously, realizing the winding or unwinding operation of yarn. At the same time, the rotating connection structure between the base plate 11 and the mounting plate 12 ensures that the entire rotating component can rotate flexibly and smoothly, reducing friction and energy loss.
[0029] In one embodiment of this utility model, such as Figures 1-5 As shown, four sliding holes 14 are provided on the outer side of the support sleeve 1, and a cross slide 43 is installed on the inner side of the lifting push plate 4. The cross slide 43 is slidably connected to the inner wall of the sliding hole 14.
[0030] Specifically, the four sliding holes 14 on the outside of the support sleeve 1 and the cross slide 43 installed on the inside of the lifting push plate 4 constitute a sliding guide mechanism. The cross slide 43 is embedded in the sliding hole 14 and can slide up and down along the hole wall. When the yarn tube 2 is lowered and squeezes the lifting push plate 4, the lifting push plate 4 moves down smoothly through the directional sliding of the cross slide 43 in the sliding hole 14 to avoid deviation. When the compression spring 42 rebounds and pushes the lifting push plate 4 up, the cross slide 43 also guides precisely along the sliding hole 14 to ensure that the lifting push plate 4 drives the yarn tube 2 to rise coaxially and cooperates with the swing stop 32 to complete the clamping.
[0031] In one embodiment of this utility model, such as Figures 1-5 As shown, an inner groove 33 is provided inside the top rod 3, and a hexagonal lifting plate 34 is slidably connected to the inner wall of the inner groove 33. A traction rope 321 is installed between the bottom of several swing stops 32 and the hexagonal lifting plate 34. A push rod 35 is installed at the top of the hexagonal lifting plate 34, and the push rod 35 protrudes from the top of the top rod 3.
[0032] Specifically, when it is necessary to disassemble the yarn tube 2, it is not necessary to rely solely on the lifting and squeezing of the yarn tube 2. The push rod 35 protruding from the top of the push rod 3 can be pressed down directly. The push rod 35 drives the hexagonal lifting plate 34 to slide down along the inner slide groove 33. The hexagonal lifting plate 34 pulls several swinging stops 32 in sync with the traction rope 321 to rotate and retract into the side slot 31. At this time, the yarn tube 2 loses the obstruction of the swinging stops 32 and can be taken out directly and quickly. After releasing the push rod 35, the hexagonal lifting plate 34 and the swinging stops 32 automatically reset under the action of the torsion spring, waiting for the next clamping.
[0033] In one embodiment of this utility model, such as Figures 1-5 As shown, a return spring 36 is installed at the bottom of the hexagonal lifting plate 34, and the return spring 36 is installed on the inner wall of the inner slide groove 33.
[0034] Specifically, when the push rod 35 is pressed, the push rod 35 drives the hexagonal lifting plate 34 to move down along the inner slide groove 33 against the elastic force of the return spring 36. The hexagonal lifting plate 34 pulls the swing stop 32 into the side slot 31 through the traction rope 321, and the yarn tube 2 can be quickly removed without obstruction. During this process, the return spring 36 is compressed again as the hexagonal lifting plate 34 moves down.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0036] Working principle: This yarn tube positioning clamp for textile machines achieves rapid clamping, stable operation, and convenient disassembly of the yarn tube through the coordinated operation of multiple components. The mounting plate 12 is fixed to the spindle or frame of the textile machine with bolts, providing a stable reference for the clamp. The transmission gear 131 at the bottom of the lower extension rod 13 meshes with the power system of the textile machine to transmit rotational power. During clamping, the yarn tube 2 is placed downward from the top end of the top rod 3. Its inner wall presses against the swing stop rod 32, causing the swing stop rod 32 to rotate around the torsion spring in the side slot 31 and retract into the slot. After the yarn tube 2 slides to the outside of the support sleeve 1, the bottom limiting slot 21 engages with the limiting strip 41 at the top of the lifting push plate 4. Continuing to lower the yarn tube 2 will press against the lifting push plate 4, causing it to slide along the sliding hole of the support sleeve 1 through the cross slide 43. 14. The spring 42 is compressed and moves smoothly downward. At this time, the swing stop 32 loses its compression and flips outward as the hexagonal lifting plate 34 returns to its original position under the rebound of the torsion spring. The lifting push plate 4 moves upward under the push of the compressed spring 42, clamping the yarn tube 2 between the swing stop 32 and the lifting push plate 4. The limiting strip 41 and the limiting groove 21 restrict the circumferential rotation of the yarn tube 2. During operation, the transmission gear 131 drives the lower extension rod 13, the base plate 11 and the support sleeve 1 to rotate synchronously, realizing the winding or unwinding of the yarn. When disassembling, press the top push rod 35 to drive the hexagonal lifting plate 34 to move downward and stretch the traction rope 321, so that the swing stop 32 is retracted into the side groove 31, and the yarn tube 2 can be taken out upward. After releasing the top push rod 35, all components automatically reset for the next clamping.
