Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of winding machine production equipment, specifically relating to a floating monitoring structure for the storage shaft of a winding machine. Background Technology
[0002] Winding machines are core equipment in the continuous material processing (such as lithium battery electrodes, textile fabrics, plastic films, metal foil strips, etc.). They temporarily store materials through a storage shaft and use a floating structure to adjust the speed difference between the preceding and following processes, ensuring that the material maintains stable tension during winding and unwinding. This is a key link in ensuring product precision (such as winding neatness and thickness uniformity) and production continuity.
[0003] However, the guide components of the floating structure of some traditional winding machines (such as single guide rails and ordinary sliders) have problems such as large fitting gaps and easy jamming, which cause the movement trajectory to deviate, resulting in unstable tension and material damage. Moreover, the current floating structure lacks a targeted sensing system, and the tension change lacks real-time data feedback, making it difficult to achieve closed-loop control and causing delays in handling production accidents. The above problems affect the production accuracy, efficiency and stability of the winding machine.
[0004] Therefore, this utility model proposes a floating monitoring structure for the storage shaft of a winding machine to solve the above problems. Utility Model Content
[0005] This invention provides a floating monitoring structure for the storage shaft of a winding machine to solve at least one of the above-mentioned technical problems.
[0006] The technical solution adopted by this utility model is as follows: a floating monitoring structure for a winding machine storage shaft, installed on the winding machine, characterized in that it includes a support component for guidance, a floating component for adjusting tension, and a sensing component for monitoring the floating state. The support component includes an upper base, a lower base, a movable slider, and a guide rail for supporting the movement of the movable slider. The floating component includes a floating wheel connected to the movable slider and a buffer for buffering the impact force of the floating wheel. The sensing component includes a support rod installed between the upper base and the lower base and multiple sensors evenly distributed on the support rod.
[0007] In a preferred embodiment, the guide rail is two parallel linear guide rails disposed between the upper base and the lower base; the movable slider is a movable shaft, and the movable shaft is provided with a limiting edge.
[0008] In a preferred embodiment, the guide rail component includes a hollow lifting column, and a lifting slide rail extending along the length of the lifting column is provided inside the lifting column; the movable slider is a T-shaped block, and the T-shaped block has a rolling bearing movably connected to the floating wheel.
[0009] In a preferred embodiment, the side wall of the T-shaped block is embedded with a plurality of balls, and the lifting slide rail is provided with grooves that cooperate with the balls.
[0010] In a preferred embodiment, the sidewall of the floating wheel is provided with a polyurethane elastomer, and a retaining edge for limiting the deflection of the strip is provided on the side away from the moving slider.
[0011] In a preferred embodiment, the sensing component further includes a timer and an alarm; the sensor is an infrared sensor.
[0012] In a preferred embodiment, the movable slider is provided with a light-shielding plate that cooperates with the infrared sensor.
[0013] In a preferred embodiment, the buffer is a hydraulic damper located on the side of the upper base facing the movable slider and on the side of the lower base facing the movable slider.
[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In a preferred embodiment of this utility model, a support component provides stable guidance, a floating component dynamically adjusts material tension, and a sensing component monitors the floating state in real time and provides feedback on any abnormalities. These three components work together to ensure the stability and reliability of the winding process. Specifically: the guide rail of the support component provides a high-precision motion path for the moving slider, ensuring that the floating component floats smoothly along a preset trajectory. The combination of these two components significantly reduces frictional resistance, minimizing jamming and impact. The floating wheel floats up and down along the guide rail under the tension of the material, maintaining stable material tension. Multiple sensors work together to reflect changes in material tension in real time, achieving closed-loop regulation.
[0015] 2. As a preferred embodiment of this utility model, when the guide rail component adopts two parallel linear guide rails and the moving slider is a moving shaft with a limiting edge, the structure forms a rigid support frame through the double guide rails, providing high-precision linear guidance, reducing lateral offset, improving tension adjustment accuracy, and the moving shaft adopts rolling elements in cooperation with the guide rails, resulting in a low coefficient of friction and fast response speed. In conjunction with the limiting edge constraining the stroke of the moving shaft, it ensures that the floating wheel floats smoothly in the vertical direction to adjust the material tension.
[0016] 3. As a preferred embodiment of this utility model, when the guide rail component adopts a hollow lifting column combined with a T-shaped locking block structure, this design achieves low-friction guidance through the engagement and sliding of the T-shaped locking block and the lifting slide rail, ensuring that the T-shaped locking block moves smoothly along the axial direction of the lifting column, improving the vertical movement accuracy of the floating wheel. Combined with the T-shaped locking block being connected to the floating wheel through a rolling bearing, the floating wheel is allowed to rotate around the bearing axis, thereby efficiently adjusting material tension and reducing wear.
[0017] In addition, the balls on the side wall of the T-shaped block are embedded in the grooves of the lifting slide rail, forming rolling friction, which greatly reduces the coefficient of friction and makes the floating wheel more sensitive to changes in tension.
[0018] 4. As a preferred embodiment of the present invention, when the side wall of the floating wheel is provided with a polyurethane elastomer and a flange is provided on one side, the material is protected by the buffering and adaptability characteristics of the polyurethane elastomer. At the same time, the flange is located on the side of the floating wheel away from the moving slider, forming an annular flange perpendicular to the material movement direction. The flange physically constrains the lateral displacement of the strip, and the two work together to improve the stability of the winding process.
[0019] 5. In a preferred embodiment of this utility model, when the sensor employs infrared sensing technology, the position change of the moving slider is detected in real time by the blocking state of the infrared beam. Combined with a timer and an alarm, rapid identification and response to abnormal working conditions such as material jamming and tape breakage are achieved. Specifically, when the floating component moves to the point of blocking the infrared beam, the receiver cannot receive the signal, and the sensor output level changes. This signal change is identified by the control system as a "position trigger." When the moving slider passes the lowest infrared sensor, the alarm is triggered, indicating a tape breakage warning. When the moving slider passes the highest infrared sensor, the timer is triggered. If the set delay is exceeded, a material jamming alarm is triggered. As the moving slider floats up and down with the slider, it will sequentially trigger tension sensors at different heights. The infrared sensor will record the tension value corresponding to the current position.
[0020] Furthermore, by using the physical action of the light-blocking plate set by the movable slider to block / release the infrared beam, the mechanical movement of the movable slider is converted into changes in electrical signals, thereby achieving accurate monitoring of the floating position, speed, and abnormal operating conditions, ensuring matching with the trigger signals of each sensor, and improving detection accuracy.
[0021] 6. In a preferred embodiment of this utility model, the hydraulic damper of the upper and lower bases serves as a buffer component. It generates a controllable damping force through the viscous resistance of the hydraulic medium. When the moving slider is floating up and down and is about to approach the upper and lower bases, it absorbs the impact energy and slows down the movement speed, thereby avoiding rigid collision between the moving slider and the upper and lower bases and preventing the components from being damaged by impact.

[0024] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0026] Furthermore, it should be understood in the description of this utility model that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0029] Example 1: A preferred embodiment, such as Figures 1-3 As shown, a floating monitoring structure for the storage shaft of a winding machine is installed at the storage shaft position of the winding machine, with the strip passing around the floating wheel 21 to form a tension path. At this time, the moving slider 13 is in the initial equilibrium position on the guide rail 14, and the multiple sensors of the sensing component 3 are not triggered.
[0030] When the winding speed is faster than the unwinding speed during material transfer, i.e., the tension increases, the pulling force of the material on the floating wheel 21 increases, pushing the floating wheel 21 to drive the moving slider 13 to move upward along the guide rail 14. When the unwinding speed is faster than the winding speed and the tension decreases, the buffer 22 releases its elastic force, pushing the moving slider 13 to drive the floating wheel 21 to move downward. The speed difference is compensated by extending the contact length of the strip at the floating wheel 21 to maintain tension stability. The difference in winding speed causes the moving slider 13 to be at different heights, and multiple sensors distributed on the support rod 31 collect the tension data of the strip in real time. Specifically, the guide rail 14 of the support component 1 ensures smooth movement of the movable slider 13, reduces frictional resistance, and improves the sensitivity of tension adjustment. For example, when the guide rail 14 is a linear guide rail 141 and the movable slider 13 is a movable shaft 131, the two parallel linear guide rails 141 are vertically fixed between the upper base 11 and the lower base 12, and the movable shaft 131 is inserted into the two guide rails. When the material tension increases (such as when the winding speed increases), the pulling force of the material on the floating wheel 21 increases, pushing the floating wheel 21 to drive the movable shaft 131 to move upward along the linear guide rail 141, compressing the buffer 22 below the upper base 11; otherwise, the opposite occurs. A limiting edge 1311 is provided on the 131, which, together with the double linear guide rail 141, ensures that the moving shaft 131 does not tilt or deviate during its movement, so that the floating wheel 21 always maintains parallel contact with the material, avoiding wrinkles or deviations in the material due to uneven force. The moving slider 13 moves with the floating wheel 21, which can help determine the limit position of the floating wheel 21. Combined with sensor data, it can confirm whether the floating range is normal, avoiding abnormal movement caused by component jamming. By utilizing the stability of the double linear guide rail 141, the precise movement of the moving shaft 131, and the safety constraint of the limiting edge 1311, the dynamic adjustment of material tension and reliable monitoring of the floating state are realized.
[0031] Example 2: like Figure 4As shown, a floating monitoring structure for the storage shaft of a winding machine differs from Embodiment 1. A hollow lifting support column 142 is vertically fixed between the upper base 11 and the lower base 12. An internal lifting slide rail 143 extends along the length of the column, forming a vertical guide channel. A T-shaped locking block 132 acts as a movable slider 13. Its lateral portion engages with the lifting slide rail 143, ensuring the block can only move up and down along the slide rail, preventing lateral deviation. Its longitudinal portion extends beyond the lifting support column 142, and the other side of the longitudinal portion is movably connected to a floating wheel 21 via a rolling bearing 1321. The floating wheel 21 can rotate freely around the rolling bearing 1321. When the unwinding and rewinding speeds of the winding machine are mismatched, causing changes in material tension, the floating wheel 21 moves up and down under the tension of the strip. At this time, the T-shaped locking block 132, connected to the floating wheel 21 via the rolling bearing 1321, slides up and down along the lifting slide rail 143 inside the lifting support column 142 under the action of tension. The engagement of the slide rail and the locking block ensures motion stability, while the free rotation of the rolling bearing 1321 ensures smooth material flow through the floating wheel 21 and reduces frictional damage between the material and the wheel. In addition, the side wall of the T-shaped locking block 132 is embedded with multiple balls 1322, and the lifting slide rail 143 is provided with a groove 1431 that matches the balls 1322, which transforms traditional sliding friction into rolling friction, reduces the friction between the T-shaped locking block 132 and the lifting slide rail 143, ensures that the floating wheel 21 can quickly respond to subtle changes in tension, improves the sensitivity of tension adjustment, and the design of the balls 1322 and the groove 1431 further plays a guiding role.
[0032] This design, through guide rails and rolling friction, ensures the stability of the floating wheel 21's movement while also taking into account the sensitivity of tension adjustment and material protection.
[0033] Example 3: like Figure 5 As shown, a floating monitoring structure for the storage shaft of a winding machine differs from Embodiment 1. The sidewall of the floating wheel 21 is wrapped with a layer of polyurethane elastomer 211, which is a highly elastic, wear-resistant polymer material with a smooth surface and a certain degree of flexibility. When the pressure of the strip on the floating wheel 21 increases, the polyurethane elastomer 211 undergoes a slight deformation due to its own elasticity, absorbing part of the pressure through deformation. On the side of the floating wheel 21 away from the moving slider 13, an annular retaining edge 212 is provided along the edge of the wheel body. Its side will contact the retaining edge 212. The retaining edge 212 restricts the material from continuing to deviate by physically blocking it, ensuring that the material always moves within the effective contact range of the floating wheel 21. Through the combined design of elastic contact and physical limitation, in addition to realizing the core function of tension adjustment, it specifically solves the problems of easy material damage and deviation during the winding process.
[0034] Example 4: like Figure 3 and Figure 4As shown, a floating monitoring structure for the material storage shaft of a winding machine differs from Embodiment 1. Multiple infrared sensors 32 evenly distributed on the support rod 31 form a monitoring array, and a light-shielding plate 133 is installed on the side of the movable slider 13 closest to the sensor. When tension fluctuations in the winding machine cause the floating wheel 21 to move the movable slider 13 up and down, the light-shielding plate 133 moves synchronously with the slider. If the tension decreases, the floating wheel 21 moves upward, and the light-shielding plate 133 moves upward accordingly, gradually blocking the light from the upper infrared sensor (triggered sequentially from bottom to top). After the infrared sensor is blocked, it immediately transmits a signal to the winding machine control system. The processor determines the floating amplitude by the position of the triggered sensor, and then calculates the degree of tension fluctuation, providing data for adjusting the winding or unwinding speed; otherwise, the opposite occurs. When the floating wheel 21 continues to float upward due to insufficient tension, and the light-shielding plate 133 completely blocks the topmost infrared sensor, the sensor is triggered and a timer starts recording the duration of the abnormality. If the material remains in a relaxed state for a long time, exceeding a preset time, the processor issues a jam warning, and the control system can prompt the operator to fine-tune parameters to avoid jamming caused by prolonged relaxation. When the floating wheel 21 continues to descend due to excessive tension, and the light-blocking plate 133 completely blocks the lowermost infrared sensor, the sensor is triggered and an alarm is activated. This immediately sends an emergency signal, forcibly alerting the operator to intervene and prevent the strip from breaking due to excessive stretching, which could lead to batch product scrapping or equipment damage. The combination of infrared sensing and the light-blocking plate 133 constitutes non-contact monitoring, avoiding the wear problems of traditional mechanical contact switches and extending the sensor's lifespan. Simultaneously, the light-blocking plate 133 is highly sensitive to infrared light blocking, accurately capturing even rapid, small vibrations of the floating wheel 21, ensuring the real-time nature and accuracy of the monitoring data.
[0035] This design avoids minor anomalies from being overlooked and prevents serious consequences caused by emergency anomalies, significantly improving the automation control level and production safety of the winding machine.
[0036] Example 5: like Figure 6 As shown, a floating monitoring structure for the storage shaft of a winding machine, which differs from Embodiment 1, has hydraulic dampers 221 installed on the side of the upper base 11 facing the movable slider 13 (i.e., the extreme direction of the upward movement of the movable slider 13) and the side of the lower base 12 facing the movable slider 13 (i.e., the extreme direction of the downward movement of the movable slider 13). The piston rod end of the damper maintains a preset safe distance from the movable slider 13.
[0037] When the winding speed of the winding machine suddenly increases, the material tension increases sharply. This pushes the floating wheel 21 to drive the moving slider 13 to move rapidly downwards. The moving slider 13 accelerates downwards along the guide structure of the support component 1. When it approaches the lower base 12, its end face contacts the piston rod of the lower hydraulic damper 221. The hydraulic oil inside the hydraulic damper 221 generates resistance through the throttling orifice. As the piston rod is compressed, the resistance gradually increases, converting the kinetic energy of the moving slider 13 into the heat energy of the hydraulic oil and releasing it slowly. This gradually reduces the downward speed of the moving slider 13, avoiding a rigid collision with the lower base 12. At the same time, the damping force reacts to the floating wheel 21 and is transmitted to the material through the floating wheel 21, relieving the instantaneous peak of tension and preventing the material from breaking due to sudden excessive force. The reverse is also true. The buffering process of the hydraulic damper 221 makes the movement of the moving slider 13 smoother, reduces the misjudgment of the sensing component 3 caused by severe vibration, and avoids direct contact between the moving slider 13 and the upper base 11 or lower base 12, thereby avoiding rigid contact and achieving the purpose of protecting the equipment.
