This structure is simple and suitable for processing scenarios with general flatness requirements.
[0003] However, due to the lack of effective tension adjustment at both ends of the material during the leveling process, localized slack or overstretching can easily occur during movement. This uneven tension distribution can cause wrinkles or slight deformation of the material after leveling, thus affecting the flatness and consistency of the finished product surface and making it difficult to meet the requirements of high-precision processing.

[0020] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-2 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing the embodiments of 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.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0023] In this embodiment of the invention, 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 or an electrical 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 embodiment of the invention according to the specific circumstances.
[0024] In one embodiment of this utility model, such as Figures 1-2 As shown, a stable and flexible tensioning and leveling device is provided, including a frame 100, a leveling main shaft 200, a pressure shaft 300, and an adjusting shaft 400. The leveling main shaft 200 is rotatably connected to the frame 100 and located in the material movement path. The pressure shaft 300 is disposed on the frame 100 and located at one end of the leveling main shaft 200, and is used to press the material onto the leveling main shaft 200. The adjusting shaft 400 is disposed on one side of the leveling main shaft 200 and the pressure shaft 300 and is located in the material movement path. The adjusting shaft 400 is slidably connected to the frame 100 and can drive the material to deviate from its original movement path. The leveling main shaft 200, the pressure shaft 300, and the adjusting shaft 400 are connected by a synchronous rotation transmission of the material. By adding an adjustable shaft 400 that can slide and allow the material to actively deviate from its original path, this structure can apply continuous and adjustable tension to the material during the leveling process. This effectively overcomes the problem of material slack or overstretching caused by insufficient tension at both ends in traditional equipment, thereby significantly reducing wrinkles and deformation on the surface of the material after leveling and improving the uniformity and consistency of the leveling effect.
[0025] like Figures 1-2 As shown, in another embodiment of this utility model, the pressure shaft 300 includes a first drive source 310, a first guide rail pair 320, and a first rotating shaft 330. The first guide rail pair 320 is disposed on the frame 100, and the end of the first rotating shaft 330 is rotatably connected to the slider of the first guide rail pair 320. The output end of the first drive source 310 is fixedly connected to the slider of the first guide rail pair 320. By precisely pushing the slider along the first guide rail pair 320 through the first drive source 310, the first rotating shaft 330 is driven to smoothly press against or away from the leveling main shaft 200, realizing controllable and stable clamping force. This avoids uneven material indentation or local wrinkles caused by shaking or skewing of the clamping mechanism in traditional methods, ensuring the linearity and consistency of the pressing process.
[0026] like Figures 1-2As shown, in another embodiment of this utility model, the first drive source 310 is a cylinder, and the slider of the first guide rail pair 320 moves towards the leveling main shaft 200. Using a cylinder as a power source provides stable and flexible linear pressure, driving the slider to move the first rotating shaft 330 along a precisely guided trajectory towards the leveling main shaft 200 to perform clamping or loosening actions. This method of operation provides rapid response and constant pressure, effectively overcoming the instantaneous relaxation or tension change of the material caused by pressure fluctuations or slow response in traditional mechanical clamping, thereby maintaining the stability of the material tension during the leveling process.
[0027] like Figures 1-2 As shown, in another embodiment of this utility model, there are two sets of the first guide rail pairs 320, which are distributed on both sides of the first rotating shaft 330. Each end of the first rotating shaft 330 is rotatably connected to the slider of the corresponding first guide rail pair 320. The output end of the first drive source 310 is fixedly connected to the slider of one set of the first guide rail pairs 320. By having the symmetrically arranged first guide rail pairs 320 on both sides jointly support and guide the first rotating shaft 330, the synchronicity and stability of its movement at both ends during the pressing process are ensured. This completely eliminates the skewness or jamming that may occur with unilateral drive, ensuring uniform pressure on the material and avoiding localized stretching or wrinkling defects caused by uneven pressure.
[0028] like Figures 1-2 As shown, in another embodiment of this utility model, the number of the first drive sources 310 is two sets, and the output ends of the two sets of first drive sources 310 are respectively fixedly connected to the sliders of the corresponding first guide rail pairs 320. By using dual drive sources to independently drive the sliders of the guide rail pairs on both sides, independent and precise control of the pressure at both ends of the first rotating shaft 330 is achieved. This allows the equipment to adapt to slight non-parallelism or changes in material thickness, and to perform adaptive leveling and clamping. This solves the problem of one end being clamped and the other loose due to structural errors or uneven materials in traditional integral drives, and significantly improves the leveling quality under different working conditions.
[0029] like Figures 1-2As shown, in another embodiment of this utility model, the adjusting shaft 400 includes a second guide rail pair 410, a second drive source 420, and a second rotating shaft 430. The second guide rail pair 410 is disposed on the frame 100. The end of the second rotating shaft 430 is rotatably connected to the slider of the second guide rail pair 410. The output end of the second drive source 420 is fixedly connected to the slider of the second guide rail pair 410. The second guide rail pair 410 is disposed on one side of the leveling main shaft 200 and the pressure shaft 300. The slider movement path of the second guide rail pair 410 is arranged in the vertical direction, and the slider movement path of the second guide rail pair 410 is designed to intersect with the material movement path. The second drive source 420 controls the slider to precisely rise and fall along the second guide rail pair 410 in the vertical direction, driving the second rotating shaft 430 to actively intervene and change the material's travel path. This applies a controllable vertical tension before or after the material enters the leveling area. This action effectively compensates for the looseness caused by the material's own stress or conveying inertia, fundamentally preventing undulations and wrinkles caused by the lack of a central tension adjustment point in the traditional leveling process.
[0030] like Figures 1-2 As shown, in another embodiment of this utility model, the adjusting shaft 400 is located on the side facing the material input end between the leveling main shaft 200 and the pressure shaft 300. Arranging the adjusting shaft 400 on the material input end side allows the material to undergo tension pretreatment and adjustment before entering the pressing area of the pressure shaft 300 and the leveling main shaft 200, eliminating initial looseness or internal stress in the incoming material in advance. This provides a uniform and stable tension foundation for subsequent leveling and pressing operations, overcoming the drawback of traditional equipment where material is directly pressed without adjustment, easily resulting in wrinkles in the inlet section.
[0031] like Figures 1-2 As shown, in another embodiment of this utility model, the adjusting shaft 400 is located on the side facing the material output end between the leveling main shaft 200 and the pressure shaft 300. Arranging the adjusting shaft 400 on the material output end side allows for secondary fine adjustment and compensation of the tension of materials that have undergone preliminary leveling but are not yet fully shaped. This effectively smooths out the minute ripples that may occur after stress release or shrinkage following leveling, ensuring the flatness of the final output product and solving the problem of poor rebound caused by the lack of tension maintenance in the later stages of leveling in traditional equipment.
[0032] like Figures 1-2As shown, in another embodiment of this utility model, there are two sets of adjusting shafts 400, with each set distributed on one side between the leveling main shaft 200 and the pressure shaft 300. By symmetrically arranging adjusting shafts 400 on both sides of the material width direction, independent and balanced tension control can be achieved on the two edge portions of the material, effectively correcting uneven tension, deviation, or edge wrinkling that may occur in the material width direction. This greatly improves the uniformity and stability of leveling wide materials and overcomes the limitation of traditional single-point adjustment, which cannot take into account the overall width.
[0033] In another embodiment of this utility model, the outer diameter of the leveling spindle 200 is larger than that of the pressure shaft 300. The increased outer diameter of the leveling spindle 200 expands its contact area with the material, making the bending and leveling process smoother and more gradual, reducing the concentrated stress per unit area. At the same time, it works with the pressure shaft 300 to form a more enveloping pressing area, effectively suppressing surface slippage, tensile deformation, or micro-wrinkles that are prone to occur when the material is severely bent, thereby improving the smoothness and consistency of the leveling.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
