Description

Technical Field

[0001] The present application relates to the field of mechanical transmission devices, and in particular to a manual rotation fine-tuning structure. Background Art

[0002] In modern industrial production, foil winding machine is a key equipment widely used in coil manufacturing and other winding processes. Its performance directly affects the quality and production efficiency of products. The mechanism in the foil winding machine usually uses a screw for movement control, and the position adjustment is achieved by the screw thread transmission of the screw. Screw transmission has been widely used due to its simple structure, high transmission efficiency, and strong load-bearing capacity.

[0003] However, the traditional screw adjustment method has some limitations in actual operation. Especially in the case of high precision requirements, the rapid movement of the screw may make it difficult to accurately control the position of the mechanism, especially when the mechanism is close to the predetermined position, the difficulty of adjustment will increase significantly. In this case, the operator needs to try many times to accurately position the mechanism, resulting in cumbersome operation, low efficiency, and prone to errors, affecting the quality of the final product.

[0004] Therefore, in the related foil winding machine, when the structure is close to the predetermined position, there is a problem of position adjustment which is complicated to operate and difficult to accurately control. Utility Model Content

[0005] In order to alleviate the problem of complicated operation and difficult precise control of position adjustment in related foil winding machines when the structure approaches a predetermined position, the present application provides a manual rotation fine-tuning structure.

[0006] The manual rotation fine-tuning structure provided in this application adopts the following technical solution:

[0007] A manual rotation fine adjustment structure, comprising:

[0008] A fixed seat, the fixed seat being arranged in the required moving mechanism;

[0009] A rotating shaft, the rotating shaft is supported by a bearing and fixedly disposed in a fixed seat, and the end of the rotating shaft is exposed and provided with an adjusting hand wheel;

[0010] A transmission toothed belt, one end of which is transmission-connected to the screw rod, and the other end of which is transmission-connected to the rotating shaft;

[0011] When the adjusting hand wheel rotates, the rotating shaft rotates together, driving the transmission belt to rotate, thereby driving the lead screw to move slightly.

[0012] By adopting the above technical solution, the rotating shaft is stably supported in the fixed seat through bearings, ensuring its high stability during rotation. An adjusting handwheel is assembled at the end of the rotating shaft, facilitating precise operation by the operator. One end of the transmission belt is connected to the lead screw, and the other end is connected to the rotating shaft. When the adjusting handwheel rotates, the rotating shaft rotates accordingly, and precisely drives the lead screw to make fine adjustments through the transmission belt. This structure enables manual rotation to be effectively converted into precise fine-tuning of the lead screw, significantly improving the adjustment accuracy and operation convenience, alleviating the problem that it is difficult to achieve minute adjustments with the traditional lead screw adjustment method, enabling fine adjustments when the mechanism approaches the predetermined position, and significantly enhancing the operation accuracy during the adjustment process. In addition, fine adjustment is achieved through intuitive rotation control, enhancing the feedback during the adjustment process and making the control of the final position more accurate.

[0013] Optionally, the outer surface of the adjusting handwheel is provided with anti-slip textures.

[0014] By adopting the above technical solution, the anti-slip textures can increase the friction force on the surface of the handwheel, effectively reducing the adjustment error caused by the palm sliding during the rotation of the handwheel. Especially when the hand sweats or the environment is humid during operation, it can ensure that the operator can accurately control the rotation of the handwheel, not only improving the operation comfort and safety, but also reducing the inaccurate adjustment caused by sliding, ensuring the stability and reliability during the fine-tuning process.

[0015] Optionally, the fixed seat and the mechanism to be moved are connected by bolts, and a shock-absorbing pad is provided between the fixed seat and the mechanism.

[0016] By adopting the above technical solution, the bolt connection ensures a firm combination between the fixed seat and the moving mechanism, providing reliable structural support and preventing loosening or displacement that may occur during operation. The addition of the shock-absorbing pad effectively absorbs and reduces the vibration transmission caused by mechanical operation or external vibration, which helps to reduce the interference of vibration on the precision adjustment process. By reducing the impact of vibration on the fine-tuning mechanism, the shock-absorbing pad not only improves the adjustment stability and accuracy, but also extends the service life of the equipment.

[0017] Optionally, a dust-proof protective cover is provided outside the rotating shaft.

[0018] By adopting the above technical solution, the dust-proof protective cover can effectively block the intrusion of external dust, dirt and other particulate matters into the rotating shaft and its bearings, thus preventing the influence of these impurities on the rotation accuracy and sliding performance of the rotating shaft. By reducing the accumulation of dust and dirt, the protective cover effectively reduces the wear and corrosion of the rotating shaft and related components, and thus extends the service life of the equipment. In addition, the dust-proof protective cover can also reduce the maintenance frequency and cleaning workload, improving the operation stability and reliability of the equipment.

[0019] Optionally, the drive toothed belt is a closed-loop structure and is made of high-strength rubber material.

[0020] By adopting the above technical solution, the drive toothed belt with a closed-loop structure can achieve continuous transmission during operation without an intermediate connecting piece, avoiding the joint problems that may occur in traditional open toothed belts, thereby reducing friction and noise during operation and improving the smoothness and reliability of transmission. The high-strength rubber material has excellent elasticity and wear resistance, can maintain stable performance during long-term use, and is not prone to aging or deformation. This material also has strong tensile resistance and corrosion resistance, ensuring the long-term durability of the toothed belt in various working environments.

[0021] Optionally, the tooth part of the drive toothed belt is designed as an inclined tooth shape.

[0022] By adopting the above technical solution, compared with the traditional straight tooth shape, the inclined tooth shape provides a larger and more uniform contact area, making the meshing between the toothed belt and the gear smoother, capable of reducing impact and vibration when transmitting power, and thus significantly reducing the noise level in the transmission system. The inclined tooth shape makes the force transmission process more continuous and stable through the way of gradual meshing, effectively reducing the friction force and the wear between the toothed belt and the gear.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By additionally providing a drive toothed belt to connect the rotating shaft and the lead screw, it is possible to finely and precisely adjust the position of the mechanism by adjusting the handwheel, achieving the precision and convenience of adjustment;

[0025] 2. By arranging a shock-absorbing pad between the fixed seat and the moving mechanism, it effectively absorbs and reduces the influence of mechanical operation or external vibration on the fine adjustment process, achieving the effect of improving the adjustment accuracy and the stability of equipment operation;

[0026] 3. By arranging anti-slip textures on the outer surface of the adjustment handwheel, it prevents adjustment errors caused by hand slipping, achieving the effect of enhancing the reliability of the fine adjustment operation. Description of the Drawings

[0032] The following further elaborates on this application in conjunction with all the attached drawings.

[0033] The embodiment of this application discloses a manually rotatable fine-tuning structure.

[0034] Referring to Figure 1 and Figure 2 , the utility model provides a manually rotatable fine-tuning structure, which is composed of key components such as a fixed seat 1, a rotating shaft 2, and a transmission toothed belt 3. The fixed seat 1 is installed on the mechanism that needs to be moved, and has the function of providing support and bearing for the rotating shaft 2. Specifically, the rotating shaft 2 is supported by a high-precision rotating bearing 21 arranged in the fixed seat 1, so that the rotating shaft 2 can maintain high stability and accuracy during rotation, thereby ensuring the reliability of the fine-tuning operation.

[0035] The fixed seat 1 is connected to the mechanism that needs to be moved through bolts 11, and this connection method ensures a firm combination between the fixed seat 1 and the moving mechanism. The bolt 11 connection provides high-strength structural support, preventing loosening or displacement caused by vibration or external forces during the operation of the equipment, thereby ensuring the stability of the entire fine-tuning mechanism. In addition, in order to further improve the anti-vibration ability of the system, a shock-absorbing pad 12 is provided between the fixed seat 1 and the moving mechanism. The shock-absorbing pad 12 is made of a high-elastic material and can effectively absorb and isolate the vibration generated during mechanical operation and the impact fluctuations in the external environment.

[0036] The addition of the shock-absorbing pad 12 not only reduces the path of vibration transmitted from the fixed seat 1 to the fine-tuning mechanism, thereby reducing the impact of vibration on the rotating shaft 2 and the transmission toothed belt 3, but also improves the accuracy of the adjustment operation. By reducing unnecessary vibration interference, the shock-absorbing pad 12 ensures the stability of the fine-tuning mechanism during operation, avoiding adjustment errors caused by vibration. In addition, the shock-absorbing pad 12 can also slow down the mechanical wear and fatigue caused by vibration, thereby extending the service life of the equipment and enhancing the overall reliability and maintainability of the equipment.

[0037] In this embodiment, an end portion of the rotating shaft 2 is exposed, and an adjusting handwheel 22 is installed at the exposed end for realizing manual operation. The adjusting handwheel 22 is fixedly connected to the rotating shaft 2 and can drive the rotating shaft 2 to rotate synchronously when the handwheel rotates. Referring to Figure 3, One end of the transmission toothed belt 3 is in transmission connection with the lead screw, and the other end is in transmission connection with the rotating shaft 2, forming a complete transmission mechanism. When the operator rotates the adjusting handwheel 22, the rotating shaft 2 rotates accordingly, and the rotational motion is precisely transmitted to the lead screw through the transmission toothed belt 3, causing the lead screw to produce a fine linear movement, thereby achieving precise adjustment of the position of the lead screw.

[0038] Traditional lead screw adjustment methods rely on motors for rotation, and it is often difficult to achieve fine displacement adjustment when approaching the target position, and it is easy to have situations of over-adjustment or under-adjustment. However, this structural design enables the manual rotation operation to be efficiently converted into precise fine adjustment of the lead screw through the coordinated action of the transmission mechanism. Specifically, when the operator applies a rotational motion through the adjusting handwheel 22, the rotating shaft 2 precisely transmits this motion to the lead screw through the transmission toothed belt 3, thereby achieving a fine linear displacement of the lead screw, significantly improving the adjustment accuracy, enabling the operator to achieve more precise control within a small displacement range, and alleviating the problem that it is difficult to make small adjustments when the traditional lead screw adjustment method approaches the predetermined position.

[0039] In this embodiment, the adopted transmission toothed belt 3 is of a closed-loop structure. Specifically, the toothed belt is a complete ring, forming a closed transmission loop, and the toothed belt is made of high-strength rubber material. The closed-loop structure design of the transmission toothed belt 3 realizes continuous and uninterrupted power transmission during operation. Since there is no need for the common intermediate connectors or joints in traditional open toothed belts, problems such as wear, fracture, or slippage that may occur at the seams are avoided. It not only simplifies the structure of the transmission mechanism but also significantly reduces the friction force during the operation of the toothed belt, reduces the noise level, thereby improving the smoothness and overall reliability of the transmission system. The stability and uniformity of power output can be ensured during continuous and uninterrupted transmission, avoiding operation errors caused by discontinuous transmission.

[0040] In addition, the high-strength rubber material adopted for the transmission toothed belt 3 has many excellent physical and chemical properties. First of all, this material has high elasticity and can maintain its original shape and function under multiple tensile, compressive, and bending conditions, which ensures that the transmission toothed belt 3 can still work stably during high-frequency use. Secondly, the rubber material has extremely strong wear resistance and can maintain a low wear rate when contacting metal or other hard materials, thereby extending the service life of the transmission toothed belt 3.

[0041] Meanwhile, the tooth part of the transmission toothed belt 3 is designed as an inclined tooth shape. Through its inclined cutting tooth surface design, a larger contact area than that of a straight tooth shape is provided. The enlarged contact area makes the meshing between the toothed belt and the gear more stable. Specifically, the inclined tooth shape makes the meshing between the toothed belt and the gear start from a point on the toothed belt and gradually transfer to the entire tooth surface, forming a progressive meshing process. This gradual contact method can reduce the instantaneous impact force at the initial stage of meshing of the toothed belt, thereby reducing the vibration and noise between the gear and the toothed belt.

[0042] In addition, a dust-proof protective cover 4 is arranged outside the rotating shaft 2. If dust and dirt enter between the rotating shaft 2 and the bearing 21, it will cause pollution of the lubricating oil, thereby increasing the friction and wear, accelerating the corrosion of components, and may cause mechanical failures. The dust-proof protective cover 4 effectively blocks the intrusion of external dust, dirt and other particulate matters into the rotating shaft 2 and its bearing 21. By reducing the accumulation of dust and dirt, the dust-proof protective cover 4 effectively reduces the wear and corrosion of the rotating shaft 2 and related components. It can not only extend the service life of the rotating shaft 2 and its bearing 21, but also reduce the maintenance cost caused by component damage or performance degradation. In addition, the dust-proof protective cover 4 also significantly reduces the maintenance frequency and cleaning workload of the equipment. By effectively blocking external pollutants, the protective cover reduces the cleaning requirements for the rotating shaft 2 system, thereby reducing the labor intensity and maintenance cost of maintenance personnel.

[0043] The implementation principle of a manual rotation fine-tuning structure in an embodiment of this application is as follows:

[0044] In this embodiment, an additional transmission toothed belt 3 is provided to connect the rotating shaft 2 and the lead screw, realizing the refined and precise adjustment of the mechanism position. The transmission toothed belt 3 effectively transmits the rotational movement of the adjusting handwheel 22 to the rotating shaft 2 and precisely drives the lead screw to move slightly. Through this setting, the position adjustment of the mechanism becomes more intuitive and the operation becomes more convenient, enabling the adjustment process to achieve high-precision control and providing users with a more efficient adjustment experience.

[0045] The addition of the shock-absorbing pad 12 can relieve vibration transmission. The material and structure design of the shock-absorbing pad 12 can effectively isolate and absorb vibrations from different sources, ensure the stability of the equipment during operation, and reduce the adjustment error caused by vibration. In addition, anti-slip textures are provided on the outer surface of the adjusting handwheel 22, and the anti-slip textures can provide a more stable holding feeling, making the control of the handwheel more precise.

[0046] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
