Description

Technical Field

[0001] The utility model relates to the technical field of winding, in particular to a winding system. Background Art

[0002] Annealing and coiling are crucial steps in the stainless steel foil manufacturing process. Due to its unique physical and chemical properties, stainless steel foil is widely used in industrial production, including electronics, chemical equipment, and food processing. With the rapid development of high-end manufacturing industries such as new energy photovoltaic solar energy and 5G smartphones, the thickness of the stainless steel foil strip products required to manufacture these high-end applications is becoming increasingly thinner.

[0003] Some stainless steel foils are only 10 to 30 microns thick and can withstand relatively little tensile stress. Therefore, stainless steel foil strips are easily affected by tension during the winding process. The stability of tension control is directly related to product quality. If the winding tension is unstable, it will lead to quality problems such as wrinkling and narrowing after winding, which will seriously reduce the product qualification rate. Utility Model Content

[0028] like Figure 1As shown, an embodiment of the present invention provides a winding system, comprising a tensioning roller assembly 3, a tension measuring device, and a winding machine 7. Along the conveying direction of the workpiece to be wound, the tension measuring device is disposed downstream of the tensioning roller assembly 3 and upstream of the winding machine 7. The winding machine 7 comprises a winding motor and a winding drum. The output shaft of the winding motor is connected to the winding drum, and the speed of the winding motor is adjustable.

[0029] By arranging a tensioning roller assembly 3, a tension measuring device, and a winder 7 along the conveying direction of the workpiece to be wound, the tension measuring device is arranged downstream of the tensioning roller assembly 3 and upstream of the winder 7. The tension measuring device is located close to the winder, facilitating accurate measurement of the tension of the workpiece to be wound during winding. When the measured winding tension is unstable, the speed of the winding motor is controlled to achieve adjustable speed of the winding drum, thereby controlling the tension of the workpiece to be wound to be as stable as possible, so that the workpiece to be wound operates at a constant tension, thereby avoiding quality issues such as wrinkling and narrowing after winding, thereby improving the product's qualified rate. The method of controlling the speed of the winding motor is prior art and can be controlled manually, semi-automatically, automatically, or in other ways, and will not be described in detail here.

[0030] Furthermore, the tension measurement device includes a tension measurement guide roller 4, a tension measurement roller support 6, a tension measuring member, and a tension measurement support 8, which are arranged in sequence along a vertical direction. The tension measurement guide roller 4 is rotatably connected to the tension measurement roller support 6, which is connected to the measuring end of the tension measuring member. The mounting end of the tension measuring member is connected to the tension measurement support 8. The workpiece to be wound passes over the upper surface of the tension measurement guide roller 4, and its tension is transmitted to the tension measuring member via the tension measurement guide roller 4 and the tension measurement roller support 6. The tension measuring member can directly display the tension value of the workpiece to be wound. The flexible rotation of the tension measurement guide roller 4 reduces the impact of frictional resistance between the tension measurement guide roller 4 and the workpiece on the tension measurement member's measurement accuracy, further improving the accuracy of the tension measurement member's measurements.

[0031] In other embodiments, the workpiece to be wound can also pass around the lower surface of the tension measuring guide roller 4 .

[0032] Furthermore, the tension measuring element utilizes an S-shaped tension gauge 5. The S-shaped tension gauge 5 has a symmetrical mounting end and measuring end, resulting in high precision, high sensitivity to tension, and more accurate tension measurement. In other embodiments, the tension measuring element may utilize other types of tension sensors.

[0033] Furthermore, the tensioning roller assembly 3 includes a first roller 31 and a second roller 32. The central axes of the first roller 31 and the second roller 32 are arranged horizontally and parallel to each other. The first roller 31 is radially spaced from the second roller 32, thereby reducing the space occupied along the length of the production line. Tension is established as the winding material passes around the first and second rollers 31 and 32. Simultaneously, a certain wrap angle is formed between the winding material and the first and second rollers 31 and 32, increasing friction and preventing slippage, thereby maintaining stable tension. After tension is established, the tension measured when the winding material passes around the tension measuring device is more accurate.

[0034] Exemplarily, the workpiece to be wound passes around the first roller 31 and the second roller 32 in an S-shape.

[0035] Furthermore, the tension measurement guide roller 4 is positioned above the tension measuring member, while the second roller 32 is positioned above the first roller 31. The first roller 31 is positioned upstream of the second roller 32, along the conveying direction of the workpiece. The highest point of the tension measurement guide roller 4 is lower than the highest point of the second roller 32, but higher than the highest point of the winding drum. The workpiece passes sequentially around the first and second rollers 31, 32, along its conveying direction. After passing the highest point of the second roller 32, the workpiece is conveyed to the highest point of the tension measurement guide roller 4, where it begins winding at the lowest point of the winding drum. The contact surface between the workpiece and the tension measurement guide roller 4 forms a sufficiently large wrap angle, increasing friction and preventing slippage. This ensures stable tension and enables accurate tension measurement.

[0036] In other embodiments, the workpiece to be wound can also be wound starting from the highest point of the winding drum.

[0037] Furthermore, the workpiece to be wound passes through the highest point of the second roller 32, the highest point of the tension measuring guide roller 4 and the winder 7 in sequence, and forms a wrap angle of 30° to 40° with the tension measuring guide roller 4, so that the tension measuring device can stably measure the tension and is less likely to slip.

[0038] Furthermore, the tension measuring guide roller 4 is made of nitrile rubber to prevent the workpiece to be wound from slipping and scratching the surface of the workpiece to be wound, thereby affecting the product qualification rate.

[0039] In other embodiments, the surface of the tension measuring guide roller 4 that is in contact with the workpiece to be wound is provided with an anti-slip layer.

[0040] Furthermore, the tension measuring guide roller 4 adopts a hollow structure to reduce the weight of the tension measuring guide roller 4 and prevent the tension measuring guide roller 4 from being too heavy and affecting the accuracy of the tension measuring device in measuring tension.

[0041] Furthermore, the axial ends of the tension measuring roller are each rotatably connected to the tension measuring roller support 6 through a bearing. The bearing structure is flexible in rotation, reducing the friction resistance between the tension measuring guide roller 4 and the workpiece to be wound, thereby reducing the impact on the measurement accuracy of the tension measuring part, and further improving the measurement accuracy of the tension measuring part.

[0042] Furthermore, the winding system further comprises a centering device, which is arranged upstream of the tensioning roller group 3 along the conveying direction of the workpiece to be wound.

[0043] Specifically, the centering device includes a CPC centering structure 1 and a centering guide roller 2. Along the conveying direction of the coiled material, the centering guide roller 2 is positioned downstream of the CPC centering structure 1 and upstream of the tensioning roller assembly 3. CPC, which stands for center potion control and abbreviated as automatic centering control system in Chinese, performs centering based on the centerline. This is a state-of-the-art technology in the field and will not be further described here.

[0044] After being centered by the CPC centering structure 1, the coiled material passes around the centering guide roller 2 and is tensioned by the tensioning roller set 3 before entering the winder 7 for rewinding. As the centered coiled material passes around the tension measuring device, the tension value measured by the S-type tension meter 5 during rewinding is accurate and stable, ensuring that the coiled material is less likely to wrinkle or narrow after rewinding, thereby improving the product's quality and yield rate.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
