DETAILED DESCRIPTION
[0028] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.
[0029] In view of the problems existing in the prior art, the utility model provides a winding device with anti-reverse function, which is described in detail below in combination with the drawings.

Figure 4 The structure schematic diagram of another winding device with anti-reverse function provided by the embodiment of the utility model is schematically shown.
[0031] As Figures 1 to 4 shown, the winding device with anti-reverse function provided by the embodiment of the utility model comprises a base assembly, a winding assembly and an anti-reverse assembly.
[0032] The base assembly is provided with the first fixed end plate 1 and the second fixed end plate 2 and is configured to fix the winding assembly and the anti-reverse assembly; the winding assembly is provided with the winding shaft 3, the winding shaft 3 is arranged between the first fixed end plate 1 and the second fixed end plate 2 and is configured to wind the target to be wound; the anti-reverse assembly is provided with the one-way rotation limiting device 4 fixed to the first fixed end plate 1 and the plurality of trigger rods 5 distributed on the winding shaft 3, and the one-way rotation limiting device 4 is configured to limit the rotation direction of the plurality of trigger rods 5.
[0033] In the embodiment, the winding device mainly comprises the base assembly, the winding assembly and the anti-reverse assembly, and through reasonable configuration and mutual cooperation, the function of anti-reverse can be effectively realized, and the stability and safety of the winding process are ensured.
[0034] Firstly, the base assembly includes a first fixed end plate 1 and a second fixed end plate 2, which functions to fix the winding assembly and the anti-reverse assembly, ensuring stable connection between various components. The base assembly can provide sufficient support during the operation of the winding device, preventing the risk of instability or looseness of the structure.
[0035] The core part of the winding assembly is the winding shaft 3, which is arranged between the first fixed end plate 1 and the second fixed end plate 2, and can achieve effective winding of the target to be wound. The winding shaft 3 can meet the overall structure and working requirements of the device, ensuring the smoothness of the winding process. During the winding process, the winding shaft 3 drives the target to be wound to rotate, and the anti-reverse assembly plays a key role in this process.
[0036] The anti-reverse assembly includes a one-way rotation limiting device 4 fixed to the first fixed end plate 1 and a plurality of trigger levers 5 distributed on the winding shaft 3. The one-way rotation limiting device 4 can limit the rotation direction of the trigger lever 5, ensuring that the winding shaft 3 can only rotate in one direction, preventing reverse rotation. Specifically, the fixed shaft 6 is fixed to the inner side of the first fixed end plate 1, the limiting block 8 is fixedly connected to the fixed shaft 6 through the bearing 7, and the limiting lever 9 is fixed to the first fixed end plate 1 and located on one side of the limiting block 8, used to limit the rotation direction of the limiting block 8.
[0037] The winding shaft 3 is provided with a plurality of trigger levers 5, which are uniformly distributed along the radial direction of the winding shaft 3. The cooperation of the trigger lever 5 and the one-way rotation limiting device 4 can further limit the occurrence of reverse rotation during the rotation of the winding shaft 3, ensuring the one-way nature of the winding operation.
[0038] In an optional embodiment, three trigger levers 5 are uniformly distributed on the winding shaft 3. These three trigger levers 5 are uniformly distributed along the radial direction of the winding shaft 3, ensuring that the trigger levers 5 can evenly exert force on the limiting device when the winding shaft 3 rotates. The function of the trigger lever 5 is to trigger the work of the limiting device, so that the one-way rotation limiting device 4 plays a role during the rotation of the winding shaft 3. When the winding shaft 3 rotates, the trigger lever 5 interacts with the limiting block 8, triggering the rotation of the limiting block 8, thereby limiting the rotation direction of the winding shaft 3. By arranging three trigger levers 5, it can be ensured that there are enough trigger points to ensure the effective work of the limiting device at any angle, avoiding the risk of reverse rotation due to insufficient trigger points.
[0039] The embodiment realizes the anti-reverse function by the close combination of the base assembly, the winding assembly and the anti-reverse assembly, and guarantees the simplicity of the structure and the convenience of the operation. Compared with the traditional cam self-locking mechanism and the ratchet pawl mechanism, the winding device has a more simple structure design, lower manufacturing and maintenance costs, and occupies a small space, and is suitable for application in occasions with lower precision requirements but higher requirements for cost and space. The design improves the universality and reliability of the device, and has a wide application prospect.
[0040] In an optional embodiment, the one-way rotation limiting device 4 is provided with a fixed shaft 6, a bearing 7, a limiting block 8 and a limiting rod 9; the fixed shaft 6 is fixed to the inner side of the first fixed end plate 1, the limiting block 8 is fixedly connected with the fixed shaft 6 through the bearing 7; the limiting rod 9 is fixed to the inner side of the first fixed end plate 1 and located on one side of the limiting block 8, and the limiting rod 9 is used for limiting the rotation direction of the limiting block 8.
[0041] In the embodiment, the one-way rotation limiting device 4 is composed of the fixed shaft 6, the bearing 7, the limiting block 8 and the limiting rod 9, and plays a role in limiting the reverse rotation of the winding shaft 3. Specifically:
[0042] The fixed shaft 6 is installed on the inner side of the first fixed end plate 1 and plays a supporting role. As a core component of the rotation limiting device, the fixed shaft 6 is connected with the first fixed end plate 1 to ensure the stability of the one-way rotation limiting device 4. Through this fixing mode, it is ensured that the one-way rotation limiting device 4 does not occur position deviation in the working process.
[0043] The limiting block 8 is connected with the fixed shaft 6 through the bearing 7, and the bearing 7 can reduce the friction between the limiting block 8 and the fixed shaft 6, so that the limiting block 8 can freely rotate on the fixed shaft 6. The limiting block 8 is an important component associated with the rotation of the winding shaft 3, responsible for limiting the rotation direction and preventing the reverse rotation of the winding shaft 3. In the rotation process, the limiting block 8 is acted on by the trigger rod 5 and can rotate in a limited manner according to the set rotation direction, achieving the effect of preventing reverse rotation.
[0044] In actual application, the limiting block 8 will stop at the vertical position due to the weight under the action of no external force. The vertical position is the initial position of the limiting block 8, that is, the position of the limiting block 8 in the natural state. Due to the weight of the limiting block 8, it will automatically stay in the vertical position by the action of gravity.
[0045] The limiting rod 9 is fixed on the inner side of the first fixed end plate 1 and is located on one side of the limiting block 8. The limiting rod 9 can limit the rotating direction of the limiting block 8, and through the interaction with the limiting block 8, it ensures that the limiting block 8 only rotates freely in one direction. When the limiting block 8 rotates to a certain predetermined position, the limiting rod 9 will prevent it from continuing to rotate, thereby effectively avoiding the occurrence of reverse rotation. The design of the limiting rod 9 ensures that the limiting block 8 is accurately limited during rotation and will not rotate beyond the set range due to external interference.
[0046] When the winding shaft 3 rotates, the trigger rod 5 acts on the limiting block 8 to make it rotate around the fixed shaft 6. The self-weight characteristics of the limiting block 8 always keep it in a vertical position without external force, thereby preventing unstable movement of the limiting block 8. Whenever the winding shaft 3 starts to rotate, the trigger rod 5 will touch the limiting block 8 and push it to a predetermined limiting position. At this time, the limiting block 8 will stay in a vertical position or a limited angle due to its own gravity, preventing the winding shaft 3 from continuing to rotate to an undesirable direction. When the rotation reaches the limiting position, the limiting block 8 will be prevented from further rotation by the blocking action of the limiting rod 9, thereby achieving the effect of preventing reverse rotation.
[0047] Specifically, when the winding shaft 3 rotates clockwise, the trigger rod 5 rotates to contact the limiting block 8, which is pushed to start rotating. The limiting block 8 rotates around the fixed shaft 6 until the trigger rod 5 and the limiting block 8 are out of contact.
[0048] The trigger rod 5 and the limiting block 8 are out of contact, and the limiting block 8 will rotate back to the initial position due to its own weight. This process relies on the self-weight of the limiting block 8 to keep it vertical or at a predetermined position, ensuring that the limiting block 8 can automatically return to its original position without external force.
[0049] When the winding shaft 3 continues to rotate clockwise, another trigger rod 5 again contacts the limiting block 8 and pushes it to continue rotating. In this way, the limiting block 8 will swing back and forth, realizing cooperation with the winding shaft 3 and allowing the winding shaft 3 to rotate without resistance.
[0050] When the winding shaft 3 rotates counterclockwise, the trigger rod 5 on the winding shaft 3 will also contact the limiting block 8 and push it to rotate around the fixed shaft 6.
[0051] When the limiting block 8 continues to rotate and touches the limiting rod 9, the limiting block 8 is clamped between the trigger rod 5 and the limiting rod 9, which effectively prevents further rotation of the rotating shaft and thereby limits the counterclockwise rotation of the winding shaft 3.
[0052] At this time, the cooperation of the trigger rod 5 and the limiting rod 9 forms an effective "locking" mechanism, making the limiting block 8 unable to swing and preventing the counterclockwise rotation of the winding shaft 3.
[0053] In an optional embodiment, the winding assembly is further provided with a winding disc assembly, the winding shaft 3 is provided with a main shaft 10, both ends of the main shaft 10 are provided with a first connecting part 11, a second connecting part 12 and a third connecting part 13 connected in sequence, and the diameters of the first connecting part 11, the second connecting part 12 and the third connecting part 13 decrease in sequence. Among them, the winding disc assembly is fixed on the first connecting part 11 at both ends of the winding shaft 3, and the plurality of trigger rods 5 are fixed on the second connecting part 12 of the winding shaft 3, and both ends of the winding shaft 3 are fixedly connected with the first fixed end plate 1 and the second fixed end plate 2 through the third connecting part 13.
[0054] In this embodiment, the winding shaft 3 is composed of a main shaft 10, and both ends of the main shaft 10 are provided with a first connecting part 11, a second connecting part 12 and a third connecting part 13 connected in sequence. The diameter of each connecting part decreases in sequence, which helps to provide good assembly performance while ensuring the stability and strength between the connecting parts. Specifically:
[0055] The first connecting part 11 is at one end of the winding shaft 3 and has the largest diameter. The main role of the first connecting part 11 is to provide a support point for the winding disc assembly. The winding disc assembly is connected with the winding shaft 3 through the first connecting part 11, which ensures that the winding disc can stably rotate with the winding shaft 3 during the working process.
[0056] The second connecting part 12 has a smaller diameter than the first connecting part 11. The plurality of trigger rods 5 are fixed on the second connecting part 12 of the winding shaft 3, and through the mutual fixation with the trigger rods 5, they cooperate with the one-way rotation limiting device 4 in the anti-reverse rotation assembly to ensure that the rotation of the winding shaft 3 can only be in one direction and prevent reverse rotation.
[0057] The third connecting part 13 is located at the end of the winding shaft 3 and has the smallest diameter. The role of the third connecting part 13 is to connect the two ends of the winding shaft 3 with the base assembly. Through the third connecting part 13, the winding shaft 3 is fixedly connected with the first fixed end plate 1 and the second fixed end plate 2, which ensures the stability of the position of the winding shaft 3 in the device and prevents displacement or loosening.
[0058] In this embodiment, the first fixed end plate 1 and the second fixed end plate 2 are both provided with a through hole matched with the third connecting part 13, and the outer side of the first fixed end plate 1 and the second fixed end plate 2 is fixed with a flange bearing seat 14 through bolts; the third connecting part 13 of the winding shaft 3 is arranged in the through hole and fixedly connected with the flange bearing seat 14.
[0059] The two ends of the winding shaft 3 are fixedly connected with the first fixed end plate 1 and the second fixed end plate 2 respectively through a third connecting part 13. In order to ensure the stability of such connection, a through hole matched with the third connecting part 13 is formed on each of the first fixed end plate 1 and the second fixed end plate 2. The third connecting part 13 of the winding shaft 3 passes through the through holes and is fixedly connected through a flange bearing seat 14.
[0060] The flange bearing seat 14 is fixed on the outer side of the first fixed end plate 1 and the second fixed end plate 2 through bolts, providing additional support force and stability. In this way, the third connecting part 13 of the winding shaft 3 can stably pass through the through hole and be fixed through the flange bearing seat 14, preventing the winding shaft 3 from shifting or loosening, thereby ensuring the reliable operation of the winding device.
[0061] According to the embodiments of the present application, stability can be maintained during winding, and the effective work of the winding disc assembly is ensured. Through the gradually decreasing design of the first connecting part 11, the second connecting part 12 and the third connecting part 13, the connection of the winding shaft 3 is more stable, and the friction of the bearing 7 is reduced, improving the working efficiency of the device. In addition, the fixed connection between the winding shaft 3 and the base assembly provides strong support through the flange bearing seat 14, further enhancing the stability and safety of the winding device.
[0062] In an optional embodiment, a limiting bolt 15 is further arranged on the first connecting part 11, and the winding disc assembly is fixed between the main shaft 10 and the limiting bolt 15; the winding disc assembly is provided with two baffle discs 16, and a sleeve ring 17 is arranged between the two baffle discs 16.
[0063] By arranging the limiting bolt 15 on the first connecting part 11 of the winding shaft 3 and fixing the winding disc assembly through the bolt, the stability of the winding disc assembly during work is ensured. At the same time, the winding disc assembly includes two baffle discs 16 and a sleeve ring 17 arranged therebetween, which further improves the stability and working performance of the winding disc assembly.
[0064] The arrangement of the limiting bolt 15 on the first connecting part 11 of the winding shaft 3 can prevent the winding disc assembly from loosening or shifting during work. Specifically, the limiting bolt 15 is located between the first connecting part 11 and the winding disc assembly, and through the fastening of the limiting bolt 15, the winding disc assembly can be firmly fixed on the winding shaft 3. The limiting bolt 15 not only provides additional fixing force, but also prevents the winding disc assembly from deviating or falling off due to vibration or external force during winding, thereby improving the reliability and stability of the winding device.
[0065] In addition, the setting of the limiting bolt 15 also plays a role in limiting the axial displacement of the winding disc assembly. During the winding process, the winding disc assembly will be subjected to certain axial force. If there is no constraint of the limiting bolt 15, the winding disc may have axial displacement, affecting the normal work of the device. Therefore, the design of the limiting bolt 15 not only ensures the fixity of the winding disc assembly, but also ensures that the relative position between the winding shaft 3 and the winding disc does not change, avoiding the problem of device damage or unstable operation caused by displacement.
[0066] The collar 17 not only plays a role in connecting the two baffle plates 16, but also ensures the relative position between the baffle plates 16. During the winding process, the collar 17 ensures that the baffle plates 16 will not be displaced due to friction or uneven force, so that the winding disc assembly can work more stably.
[0067] In an optional embodiment, the winding shaft 3 is fixed with a hand wheel 18 and a coupling 19 at both ends, respectively. The hand wheel 18 is located on the outside of the first fixed end plate 1, and the coupling 19 is located on the outside of the second fixed end plate 2. The outside of the second fixed end plate 2 is also provided with a fixing seat 20.
[0068] In this embodiment, the hand wheel 18 is fixed on the outside of the first fixed end plate 1 of the winding shaft 3. The hand wheel 18 is a component for manually operating the winding shaft 3, and is usually used to adjust the winding speed. In this scheme, the hand wheel 18 is located on the outside of the winding device, which is convenient for the operator to manually adjust, especially in the case of not needing electric drive or fine control. The position of the hand wheel 18 is set on the outside of the first fixed end plate 1, which helps to improve the convenience and flexibility of operation, ensuring that the operator can easily adjust the rotation of the winding shaft 3 during winding operation, thereby realizing control during the winding process.
[0069] The coupling 19 is fixed on the outside of the second fixed end plate 2 of the winding shaft 3. The main function of the coupling 19 is to connect the winding shaft 3 with an external power source (such as a motor, a transmission system, etc.). Through the setting of the coupling 19, the winding device can input power when needed, supporting automatic or mechanized operation. The position of the coupling 19 is set on the outside of the second fixed end plate 2, which simplifies the connection mode between the winding shaft 3 and the power source, reduces the complex transmission structure, and enables the coupling 19 to be more stably connected with external equipment, ensuring smooth and reliable power transmission during the winding process.
[0070] The outer side of the second fixed end plate 2 is provided with a fixed seat 20, and the main function of the fixed seat 20 is to firmly fix the external power source (such as a motor or other driving device) on the winding device. The fixed seat 20 is connected with the power source by bolts or other fixing methods, and provides a stable installation foundation for the power source. Since the external power source plays a crucial role in the winding device, the design of the fixed seat 20 can ensure that the power source does not shift or loosen during operation, thereby avoiding the problem of unstable operation or damage of the device caused by insecure fixation.
[0071] In actual application, assuming that the anti-reverse winding device is applied to a material winding system on a production line, it aims to effectively prevent reverse rotation caused by operation errors or external interference during winding. In this scenario, the various components of the device need to work together closely to ensure stability and safety during production.
[0072] First of all, the operation of the winding device is realized by the orderly cooperation of the base assembly, winding assembly and anti-reverse assembly. On the production line, the base assembly plays a crucial role by fixing the first fixed end plate 1 and the second fixed end plate 2, ensuring that the entire device is stable and not prone to displacement during production. The design of the base assembly can provide necessary support and protection for other components, avoiding the risks caused by loose structure.
[0073] The core part of the winding assembly is the winding shaft 3, which is installed between the first fixed end plate 1 and the second fixed end plate 2 and connected with the target to be wound. At this time, the winding shaft 3 drives the target to be wound to rotate clockwise. In this process, the anti-reverse assembly plays a crucial role by preventing the winding shaft 3 from rotating counterclockwise, ensuring the stability of the winding process.
[0074] Specifically, the anti-reverse assembly includes a one-way rotation limiting device 4 fixed on the first fixed end plate 1 and a plurality of trigger levers 5 distributed on the winding shaft 3. The trigger levers 5 are evenly distributed along the radial direction of the winding shaft 3, and whenever the winding shaft 3 rotates, the trigger levers 5 come into contact with the limiting blocks 8, pushing the limiting blocks 8 to rotate around the fixed shaft 6. When the limiting blocks 8 rotate to the set position, the limiting rods 9 limit the rotation of the limiting blocks 8, preventing the winding shaft 3 from continuing to rotate and avoiding the occurrence of reverse rotation.
[0075] When the winding shaft 3 rotates clockwise, the contact between the trigger lever 5 and the limiting block 8 pushes the limiting block 8 to rotate, and after the contact with another trigger lever 5 is broken, the limiting block 8 restores to the initial position by its own weight. At this time, the winding shaft 3 continues to rotate clockwise, and another trigger lever 5 again comes into contact with the limiting block 8, continuing to push the limiting block 8 to rotate, realizing the cooperation with the winding shaft 3 and ensuring the free rotation of the winding shaft 3 in the clockwise direction.
[0076] However, when the winding shaft 3 begins to rotate counterclockwise, the trigger lever 5 contacts the limiting block 8, pushes the limiting block 8 to rotate and finally touches the limiting rod 9. At this time, the limiting block 8 is clamped by the limiting rod 9, forming an effective "locking" mechanism to prevent the winding shaft 3 from continuing to rotate counterclockwise. The cooperation of the limiting rod 9 and the trigger lever 5 effectively prevents the winding shaft 3 from reversing, ensuring the safe operation of the device.
[0077] In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more than two; The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
