Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to a warp beam clamping device and a sizing machine. Background Technology

[0002] In the sizing process of the textile industry, the warp beam unwinding device is a key piece of equipment for controlling yarn tension. Currently, the mainstream unwinding device adopts a passive friction tension control method. Its working principle is to adjust the air pressure output through a proportional valve, drive the pressurizing cylinder to act, and cause the chain with several friction blocks installed to press the warp beam friction disc. The frictional resistance hinders the free unwinding of the warp beam, thereby forming a stable yarn unwinding tension.

[0003] However, existing friction chain structures have significant limitations: the friction blocks are typically evenly distributed on the chain, and during the loading and unloading of the warp beam, the position of the friction blocks must be manually adjusted to cover the warp beam friction disc. This operation is not only cumbersome and inefficient, but also increases the labor intensity of workers and is prone to tension fluctuations or equipment wear due to improper human operation. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a warp beam clamping device and sizing machine to achieve rapid adjustment of friction pressure and loading and unloading of warp beams, thereby improving the convenience, stability and intelligence of equipment operation.

[0006] In a first aspect, embodiments of this application provide a warp beam clamping device, the warp beam clamping device comprising:

[0007] A friction assembly, comprising a pair of friction elements and a driving element, wherein the pair of friction elements are symmetrically arranged about a central plane, and the driving element is used to drive the pair of friction elements to move closer to or further away from each other;

[0008] The centering assembly includes a pair of rolling elements arranged side-by-side and spaced apart. Each rolling element has a rotating surface and a rotation axis. The rolling elements are rotatable about the rotation axis. The axis of the rotating surface and the rotation axis are collinear. The rotating surface of the pair of rolling elements is used to abut against and support the outer peripheral surface of the warp friction disc.

[0009] In some embodiments of the first aspect, the rolling element is configured as a support roller.

[0010] In some embodiments of the first aspect, the friction element includes a connecting block and a friction block, the friction block and the connecting block being detachably connected.

[0011] In some embodiments of the first aspect, the friction block has a working surface, which is configured as an arcuate surface, and the working surface abuts against the circumference of the warp friction disc.

[0012] In some embodiments of the first aspect, the drive includes:

[0013] The device includes a swinging part and a driving part, which are connected and hinged to the friction element. The driving part is used to drive the swinging part to rotate around a first axis to move closer to or away from the warp friction disk. The first axis is parallel to the rotation axis of the rolling element.

[0014] In some embodiments of the first aspect, the drive unit includes:

[0015] The mounting element and the telescopic element have a fixed end and a telescopic end. The middle part of the swinging part is hinged to the mounting element. One end of the swinging part is hinged to the telescopic end of the telescopic element. The other end of the swinging part is hinged to the friction element. The fixed end of the telescopic element is hinged to the mounting element.

[0016] In some embodiments of the first aspect, the mounting element has a pair of limiting blocks defining a mounting area between the pair of limiting blocks, and the warp friction disc is located within the mounting area.

[0017] In some embodiments of the first aspect, the warp beam clamping device further includes:

[0018] A limiting assembly includes a limiting wheel, which is rotatably connected to the mounting element. The rotating surface of the limiting wheel can abut against the end face of the warp friction disc, and the axis of the limiting wheel is perpendicular to the axis of rotation.

[0019] Secondly, embodiments of this application also provide a sizing machine, the sizing machine including a warp beam frame and a warp beam clamping device as described in any of the above embodiments, the warp beam clamping device being disposed on the warp beam frame.

[0020] In some embodiments of the second aspect, the warp support includes a rotatable shaft connected to a mounting element.

[0021] The embodiments of this application have the following advantages:

[0022] This application provides a warp beam clamping device. A friction assembly, driven by a drive unit (such as a cylinder or servo motor), synchronously drives a pair of symmetrically arranged friction components (such as friction blocks or friction belts) to move closer together, forming a controllable clamping force with the warp beam friction disc. By adjusting the clamping degree of the friction components, the frictional resistance during warp beam unwinding can be precisely controlled, thereby stabilizing yarn tension. The symmetrical design ensures uniform distribution of frictional pressure, avoiding warp beam skewing or unilateral wear, and improving tension stability. A pair of rolling components (such as rollers or bearings) of the centering assembly support the outer circumference of the warp beam friction disc through a rotating surface and roll accordingly as the warp beam rotates, reducing frictional resistance. The spaced arrangement and synchronous rotation function of the rolling components can adapt to warp beam friction discs of different diameters, achieving automatic centering, ensuring concentricity during warp beam installation, and reducing runout and tension fluctuations. When loading and unloading the warp beam, the drive unit can quickly separate the friction components, expanding the operating space; the rolling components of the centering assembly assist in guiding the positioning of the warp beam friction disc, eliminating the need for manual adjustment of the friction block position and simplifying the process.

[0023] Therefore, by automatically adjusting the position of the friction components through a drive mechanism, the manual operation of hanging and removing friction blocks is replaced, significantly reducing labor intensity, shortening warp beam changeover time, and improving production efficiency. The symmetrical friction assembly avoids uneven pressure loading, and the centering design of the rolling components reduces eccentric rotation of the warp beam. With this dual protection, yarn tension fluctuations are smaller, resulting in superior sizing quality.

[0046] In the sizing process of the textile industry, the warp beam unwinding device is a key piece of equipment for controlling yarn tension. Currently, the mainstream unwinding device adopts a passive friction-based tension control method. Its working principle is to adjust the air pressure output through a proportional valve, which drives the pressurizing cylinder to press the chain with several friction blocks 111 against the warp beam friction disc 20. The frictional resistance hinders the free unwinding of the warp beam, thereby forming a stable yarn unwinding tension. However, the existing friction chain structure has obvious limitations: the friction blocks 111 are usually evenly distributed on the chain. During the loading and unloading of the warp beam, the position of the friction blocks 111 must be manually hung or adjusted to cover the warp beam friction disc 20. This operation method is not only cumbersome and inefficient, but also increases the labor intensity of workers and is prone to tension fluctuations or equipment wear due to improper operation.

[0047] As shown in Figure 1 to Figure 3 As shown, in order to solve the above-mentioned technical problems, this application provides a warp beam clamping device 10. The warp beam clamping device 10 includes a friction assembly 100 and a centering assembly. The friction assembly 100 includes a pair of friction elements 110 and a driving element 120. The pair of friction elements 110 are symmetrically arranged about the centering surface. The driving element 120 is used to drive the pair of friction elements 110 to move closer or further away from each other.

[0048] The centering component includes a pair of rolling elements arranged side by side and spaced apart. Each rolling element has a rotating surface and a rotation axis. The rolling elements are capable of rotating about the rotation axis. The axis of the rotating surface and the rotation axis are collinear. The rotating surface of the pair of rolling elements is used to abut against and support the outer peripheral surface of the shaft friction disk 20.

[0049] In these embodiments, this application provides a warp beam clamping device 10 for tension control and loading / unloading operations of the warp beam during the sizing process. The device comprises two main parts: a friction assembly 100 and a centering assembly, which respectively provide pressing control and positioning support for the warp beam friction disc 20.

[0050] A pair of friction elements 110 are symmetrically arranged about a central plane, which is a vertical plane passing through the center line of the meridian. Each friction element 110 includes a friction block 111 and a mounting bracket, the friction block 111 being fixed to the mounting bracket and extending toward the central plane.

[0051] The driving component 120 adopts a pneumatic or electric linear drive mechanism, such as a cylinder or servo cylinder, with two mounting brackets connected to its two ends respectively, for driving the pair of friction components 110 to move closer or further apart in the horizontal direction.

[0052] When it is necessary to apply unwinding tension to the warp beam, the drive unit 120 is activated, pushing the two friction units 110 to move towards the centering surface until the friction blocks 111 contact and press against the two sides of the warp beam friction disk 20. The rotation speed of the warp beam is controlled by the frictional resistance, thereby forming a stable unwinding tension.

[0053] When it is necessary to load or unload the shaft, the drive component 120 moves in the opposite direction, causing the friction component 110 to move away from the centering surface and releasing the friction disc. At this time, the friction pressure can be quickly released without manual intervention, thus improving loading and unloading efficiency.

[0054] Each rolling element has a rotating surface and a rotation axis, with the axis of the rotating surface collinear with the rotation axis, preferably a cylindrical structure. The rolling elements are supported on the frame by bearings, allowing them to rotate freely about the rotation axis.

[0055] The rotating surface of the rolling element abuts against and supports the outer circumferential surface of the warp friction disk 20, serving as an auxiliary positioning and centering element. When the friction assembly 100 is in the released state, the rolling element can stably support the warp friction disk 20, preventing it from shifting or shaking, thereby ensuring the safety and stability of the loading and unloading process.

[0056] In addition, since the rolling elements can rotate freely, they can also play a certain role in reducing friction during the clamping process of the friction assembly 100, thereby reducing the sliding friction between the friction disc and the rolling elements and extending the service life of the equipment.

[0057] For example, a pair of scroll members are spaced apart in the horizontal direction.

[0058] For ease of understanding, the workflow is as follows: The warp beam to be clamped is moved to the designated position, with its friction disc positioned between the friction assembly 100 and the centering assembly. The rolling elements automatically abut against the outer periphery of the friction disc, providing initial positioning and support. The drive unit 120 is activated, driving the two friction elements 110 to move closer to the centering surface. The friction blocks 111 contact and press against both sides of the friction disc, forming the required unwinding tension. During the sizing process, the friction pressure is dynamically adjusted by regulating the pressure output of the drive unit 120 to adapt to the needs of different yarn types or process parameters. When the warp beam needs to be replaced, the drive unit 120 reverses its direction, the friction elements 110 reset, and the friction disc is released. The rolling elements maintain their support for the friction disc, facilitating quick loading and unloading.

[0059] For example, the drive element 120 can be an alternative form such as a hydraulic cylinder or an electric actuator. Alternatively, the rolling element can be a tapered roller, a V-roller, or other structure adapted to the shape of the friction disc.

[0060] In other words, the friction assembly 100 synchronously drives a pair of symmetrically arranged friction elements 110 (such as friction blocks 111 or friction belts) to move closer to each other via a drive element 120 (such as a cylinder or servo motor), forming a controllable clamping force with the warp beam friction disk 20. By adjusting the clamping degree of the friction elements 110, the frictional resistance during warp beam unwinding can be precisely controlled, thereby stabilizing yarn tension. The symmetrical design ensures uniform distribution of frictional pressure, avoids warp beam skewing or unilateral wear, and improves tension stability. A pair of rolling elements (such as rollers or bearings) of the centering assembly support the outer circumference of the warp beam friction disk 20 through a rotating surface and roll accordingly when the warp beam rotates, reducing frictional resistance. The spaced arrangement and synchronous rotation function of the rolling elements can adapt to warp beam friction disks 20 of different diameters, achieving automatic centering, ensuring concentricity during warp beam installation, and reducing bounce and tension fluctuations. When loading and unloading the warp beam, the drive unit 120 can quickly separate the friction unit 110, expanding the operating space; the rolling element of the centering component assists in guiding the warp beam friction disk 20 to be positioned, eliminating the need for manual adjustment of the position of the friction block 111 and simplifying the process.

[0061] Therefore, by automatically adjusting the position of the friction element 110 through the drive component 120, the manual operation of hanging and removing the friction block 111 is replaced, significantly reducing labor intensity, shortening the warp beam replacement time, and improving production efficiency. The symmetrical friction assembly 100 avoids uneven pressure loading, and the centering design of the rolling element reduces the eccentric rotation of the warp beam. With these two safeguards, the yarn tension fluctuation is smaller, and the sizing quality is better.

[0062] In some embodiments, the rolling element is configured as a support roller.

[0063] In these embodiments, a pair of rolling elements are specifically configured as support rollers. Each support roller has a rotating surface and a rotation axis, with the axis of the rotating surface collinear with the rotation axis, forming a cylindrical or slightly tapered surface to better fit the outer peripheral shape of the radial friction disc 20.

[0064] The support rollers are supported on the frame by bearings, allowing them to rotate freely around their own axis of rotation. To increase support stability and reduce wear, the support rollers can be made of high-strength, wear-resistant materials, such as engineering plastics, ceramics, or specific alloy steels.

[0065] After the rolling element is set as a support roller, its main function remains to abut and support the outer circumferential surface of the shaft friction disk 20. However, compared with ordinary rolling elements, the support roller provides a more stable support and positioning effect. Because the support roller can provide a more uniform pressure distribution at the contact point, and its rotational characteristics help reduce sliding friction with the friction disk, it effectively reduces the risk of wear and improves the service life of the equipment.

[0066] In addition, when the friction assembly 100 is released, the support roller can not only stably support the warp shaft friction disc 20 and prevent it from shifting or shaking, but also play a guiding role during loading and unloading, making it easy to complete the warp shaft clamping operation quickly and accurately.

[0067] Move the warp beam to be clamped to the designated position, ensuring its friction disc is above the support roller. The support roller abuts against the outer circumference of the friction disc, achieving initial positioning and support. Due to the special design of the support roller, a more precise centering effect can be provided. The drive unit 120 is activated, driving the two friction elements 110 to move closer to the centering surface M. The friction blocks 111 contact and press against both sides of the friction disc, forming the required unwinding tension. During the sizing process, the friction pressure is dynamically adjusted by regulating the pressure output of the drive unit 120 to adapt to the needs of different yarn types or process parameters. During this period, the support roller maintains stable support for the friction disc, ensuring precise centering throughout the process. When the warp beam needs to be replaced, the drive unit 120 reverses its movement, the friction elements 110 reset, and the friction disc is released. At this time, the support roller continues to provide support until the new warp beam is installed.

[0068] In some embodiments, the friction element 110 includes a connecting block 112 and a friction block 111, which are detachably connected.

[0069] In these embodiments, the connecting block 112 is used to connect with the drive component 120 and serves as the mounting base for the friction block 111. The friction block 111 is a key component that directly contacts the radial friction disc 20 and generates frictional resistance. The friction block 111 and the connecting block 112 are fixed by a detachable connection method, such as through threaded connection, snap-fit ​​connection, plug-in structure, pin connection, etc., to achieve quick assembly and disassembly. This design facilitates the individual replacement of the friction block 111 after wear, avoiding the need to replace the entire friction component 110, thereby reducing maintenance costs and material waste.

[0070] In this embodiment, the friction block 111 is fixed to the front end face of the connecting block 112 by at least two positioning screws, and is provided with guide grooves or positioning protrusions to ensure installation accuracy and stability. In addition, the connecting block 112 may also be provided with weight reduction holes or heat dissipation structures to optimize overall performance.

[0071] Since the friction block 111 frequently comes into contact with the high-speed rotating friction disc during operation, its surface is prone to wear. Therefore, it is preferable to use wear-resistant, high-temperature resistant, and elastic materials, such as polymer composites, carbon fiber reinforced resin, and ceramic-coated metals. Friction blocks 111 made of different materials can be replaced according to the type of yarn, operating speed, or tension requirements to achieve the best control effect.

[0072] For example, the shape of the friction block 111 can be customized according to the contour of the friction disc, such as arc, V-shape or multi-point contact structure. Multiple friction blocks 111 can be modularly spliced ​​on the connecting block 112 to accommodate warp friction discs 20 of different widths or diameters.

[0073] In some embodiments, the friction block 111 has a working surface, which is configured as an arcuate surface, and the working surface abuts against the periphery of the radial friction disk 20.

[0074] In these embodiments, the friction block 111 has a working surface for contacting the warp friction disk 20. The working surface is configured as an arc surface, the curvature of which is adapted to the outer peripheral contour of the warp friction disk 20. For example, when the warp friction disk 20 is cylindrical, the radius of the arc surface is slightly larger than or equal to the radius of the friction disk to achieve surface contact rather than point contact or line contact.

[0075] This curved working surface design offers the following advantages:

[0076] Compared to flat or irregular shapes, curved surfaces can be more evenly distributed on the outer periphery of the friction disc, thereby improving the stability and reliability of friction force transmission. Due to the increased contact area, the pressure per unit area decreases, helping to reduce localized wear on the friction block 111 and the friction disc, extending their service life. In actual use, certain assembly deviations or slight eccentricity of the warp beam may occur; the curved surface has a certain tolerance and can automatically conform to the friction disc surface, maintaining good contact. More stable frictional contact helps to form a more uniform and controllable unwinding tension, improving the consistency of sizing quality.

[0077] Under the action of the driving component 120, the two friction blocks 111 approach each other synchronously from both sides, so that the arc-shaped working surface is tightly attached to and presses against the friction disc to form a stable friction pair.

[0078] In some embodiments, the drive member 120 includes a swing portion 121 and a drive portion 122, which are connected together. The swing portion 121 is hinged to the friction member 110. The drive portion 122 is used to drive the swing portion 121 to rotate about a first axis to move closer to or away from the radial friction disk 20. The first axis is parallel to the rotation axis of the rolling member.

[0079] In these embodiments, the swinging part 121 is a linkage or swing arm structure, one end of which is hinged to the friction member 110 (such as the connecting block 112). The driving part 122 is a power source component, such as a cylinder, hydraulic cylinder, servo motor or stepper motor, etc., and its output end is connected to the swinging part 121 to drive the swinging part 121 to rotate around a set first axis.

[0080] The first axis is the rotation center line of the swing part 121, and is parallel to the rotation axis of the rolling element (e.g., the support roller). This arrangement is conducive to the coordination and unity of the overall structural layout, and facilitates mechanical linkage and space optimization.

[0081] When it is necessary to press the warp friction disc 20, the drive unit 122 is activated, driving the swing unit 121 to rotate around the first axis. Since the swing unit 121 is hinged to the friction member 110, its rotational motion is converted into the action of the friction member 110 moving towards the centering surface along a predetermined trajectory, ultimately causing the working surface of the friction block 111 to contact and press against both sides of the friction disc, forming unwinding tension.

[0082] When it is necessary to release friction pressure for loading and unloading operations, the drive unit 122 moves in the opposite direction, causing the swing unit 121 to rotate in the opposite direction, thereby driving the friction element 110 away from the centering surface and relieving the pressure on the friction disc.

[0083] The opening and closing of the friction element 110 is controlled by rotational motion, saving lateral installation space. The hinged structure combined with the rotary drive reduces impact and vibration, improving the stability of equipment operation. The drive unit 122 and the swing unit 121 can be connected via a standard interface, facilitating disassembly and replacement.

[0084] For example, the swing part 121 is a swing arm. Of course, the swing part 121 can be a multi-section linkage structure to achieve more complex motion trajectories.

[0085] For example, the drive unit 122 may also be an alternative form such as a pneumatic motor, a hydraulic motor, or a gear and rack mechanism.

[0086] In some embodiments, the drive unit 122 includes a mounting element 400 and a telescopic element having a fixed end and a telescopic end. The middle part of the swing part 121 is hinged to the mounting element 400, one end of the swing part 121 is hinged to the telescopic end of the telescopic element, the other end of the swing part 121 is hinged to the friction member 110, and the fixed end of the telescopic element is hinged to the mounting element 400.

[0087] In these embodiments, each friction element 110 is connected to a separate drive unit 122, and the mounting element 400 is a fixed bracket or base for mounting the entire drive structure onto the frame of the sizing machine. The telescopic element can be an actuator with linear reciprocating motion output function, such as a cylinder, hydraulic cylinder, or electric push rod, and has a fixed end and a telescopic end. The swinging part 121 is a rigid linkage structure with three key connection points:

[0088] The middle part is hinged to the mounting element 400, forming the rotation fulcrum of the swing part 121;

[0089] One end is hinged to the telescopic end of the telescopic element, receiving the push and pull force from the telescopic element;

[0090] The other end is hinged to the friction element 110 (such as the connecting block 112) to transmit the rotational motion of the swing part 121 to the friction element 110.

[0091] Meanwhile, the fixed end of the telescopic element is also hinged to the mounting element 400, forming a stable force support.

[0092] When it is necessary to press the friction disc 20, the telescopic end of the telescopic element extends outward, pushing the swing part 121 to rotate upward around the central hinge point, thereby driving the friction element 110 hinged to the end of the swing part 121 to move towards the centering surface, so that the working surface of the friction block 111 contacts and presses the two sides of the friction disc, thus achieving tension control.

[0093] When it is necessary to release the friction pressure, the telescopic element retracts, causing the swing part 121 to rotate in the opposite direction, thereby moving the friction element 110 away from the centering surface, relieving the pressure on the friction disc, and facilitating the quick loading and unloading of the warp shaft.

[0094] In one specific embodiment, the telescopic element employs a double-acting cylinder. Its fixed end is connected to the mounting element 400 via a trunnion, and its telescopic end is hinged to the front end of the swing part 121 via a ball joint. The swing part 121 is a U-shaped connecting rod, with its middle section hinged to the mounting element 400 via a pivot, and its rear end connected to the friction element 110. Under the push of the cylinder, the U-shaped connecting rod rotates around its middle section, causing the friction element 110 to complete the pressing action.

[0095] In some embodiments, the mounting element 400 has a pair of limiting blocks 500, with a mounting area defined between the pair of limiting blocks 500, and the shaft friction disc 20 is located within the mounting area.

[0096] In these embodiments, a pair of limiting blocks 500 are respectively disposed on both sides of the drive structure, defining a mounting area between them. This mounting area is used to accommodate and position the warp friction disc 20.

[0097] The limiting block 500 is preferably a plate-shaped structure made of metal or engineering plastic, and its inner surface can be configured to conform to the outer contour of the radial friction disc 20, such as a plane, an arc surface, or a combination of curved surfaces. The limiting block 500 is fixed to the mounting element 400 by screws, pins, or other detachable means, so as to facilitate replacement or adjustment according to different friction disc sizes.

[0098] Integrating the limit block 500 onto the mounting element 400 provides the following functions and advantages:

[0099] The installation area formed by the limiting block 500 provides initial positioning for the warp shaft friction disc 20, ensuring it is in the predetermined position and preventing poor frictional contact due to misalignment. During the clamping process of the friction block 111, the limiting block 500 effectively restricts the lateral movement of the friction disc, improving the stability of tension control. The limiting block 500 not only serves a positioning function but also acts as part of the support structure, enhancing the structural strength of the entire drive system. Because the limiting block 500 uses a detachable connection, the appropriate limiting structure can be quickly replaced according to different models of friction discs, improving equipment versatility. When loading and unloading the warp shaft, operators do not need to repeatedly adjust the position of the friction disc; simply placing it into the installation area completes the initial positioning, significantly improving work efficiency.

[0100] In some embodiments, the warp beam clamping device 10 further includes a limiting component, which includes a limiting wheel 300. The limiting wheel 300 and the mounting element 400 are rotatably connected. The rotating surface of the limiting wheel 300 can abut against the end face of the warp beam friction disk 20. The axis of the limiting wheel 300 and the axis of rotation are perpendicularly arranged.

[0101] In these embodiments, the warp beam clamping device 10 further includes a limiting component for axially limiting the warp beam friction disc 20 to prevent it from axially shifting or deviating during operation.

[0102] The limiting assembly includes a limiting wheel 300, which is rotatably connected to the mounting element 400 via a bearing or a shaft, allowing it to rotate freely about its own axis. The rotating surface of the limiting wheel 300 is used to contact the end face of the shaft friction disc 20, serving to limit and guide the movement.

[0103] Furthermore, the axis of the limiting wheel 300 is set perpendicular to the rotation axis of the rolling element (such as the support roller), forming an orthogonal layout in three-dimensional space. This structural arrangement helps to improve the structural coordination and functional complementarity of the overall system.

[0104] Integrating the limit wheel 300 into the limit assembly provides the following functions and advantages:

[0105] The rotating surface of the limiting wheel 300 abuts against the end face of the friction disc, preventing axial displacement of the friction block 111 during clamping and improving the stability of tension control. Because the limiting wheel 300 is a rotating structure, its contact with the end face of the friction disc is rolling friction, significantly reducing wear and resistance compared to sliding friction. The limiting wheel 300 automatically adjusts its contact angle to accommodate slight displacement of the friction disc, ensuring a good fit. During loading, unloading, or operation, if the warp shaft shows a tendency to move axially, the limiting wheel 300 provides timely reverse support to prevent equipment damage or yarn breakage. The limiting wheel 300 adopts a modular design, allowing for quick disassembly and replacement, and is suitable for different sizes of friction disc end faces.

[0106] In one specific embodiment, the limiting wheel 300 has a disc-shaped structure, and its outer peripheral surface is provided with anti-slip texture to enhance contact stability. The limiting wheel 300 is mounted on the side of the mounting element 400 via a short shaft. When the friction block 111 presses against the friction disc, the limiting wheel 300 simultaneously contacts its end face, together forming a complete three-dimensional positioning system.

[0107] like Figure 4 As shown, in some embodiments, this application also provides a sizing machine, which includes a warp beam frame 30 and a warp beam clamping device 10 as described in any of the above embodiments, the warp beam clamping device 10 being disposed on the warp beam frame 30.

[0108] Since the warp beam clamping device 10 has the above-mentioned technical effects, the sizing machine including the warp beam clamping device 10 should have the same technical effects, which will not be repeated here.

[0109] In some embodiments, the bearing bracket 30 includes a rotatable shaft 600 connected to a mounting element 400.

[0110] In these embodiments, the rotatable shaft 600 is used to support one end of the warp shaft and allows it to rotate synchronously with the warp shaft. The rotatable shaft 600 is preferably a bearing support structure, providing good rotational accuracy and load-bearing capacity.

[0111] The rotatable shaft 600 is fixedly connected to or integrally formed with the mounting element 400 in the aforementioned embodiment. That is, the mounting element 400 is directly mounted on the rotatable shaft 600 as part of the drive unit 122, so that the entire warp shaft clamping device 10 can rotate or adjust its position together with the rotatable shaft 600.

[0112] Because the mounting element 400 is rigidly connected to the rotatable shaft 600, the friction assembly 100 always remains coaxial with the warp shaft friction disc 20, avoiding uneven tension caused by eccentricity. When the rotatable shaft 600 drives the warp shaft to rotate to a specific angle, the clamping device can automatically enter or disengage from the working position, improving operational convenience.

[0113] For example, the limit wheel 300 is rotatably mounted on the rotatable shaft 600.

[0114] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0115] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0116] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
