Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic film winding technology, and in particular to a tension-adaptive automatic winding control device for aluminum-plastic film. Background Technology

[0002] The tension-adaptive automatic winding control device for aluminum-plastic film is mainly used in the production process of aluminum-plastic film to automatically adjust the tension of the film material and ensure the uniformity and stability of the film roll. Traditional winding methods often rely on manual labor or fixed parameters, which cannot adapt to different material characteristics and working conditions. Adaptive control technology improves production efficiency and product quality and reduces scrap rate and operation difficulty through real-time monitoring and adjustment.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing tension-adaptive automatic rewinding control device for aluminum-plastic film cannot adaptively adjust the tension of the aluminum-plastic film during rewinding according to the demand, and it is inconvenient to take out the rewound aluminum-plastic film roll. Excessive or insufficient tension will cause wrinkles, loosening or overstretching of the aluminum-plastic film during the rewinding process, resulting in uneven film roll density, which affects subsequent processing and use. Excessive tension fluctuations or local stress concentration may cause scratches, damage or tearing on the surface of the aluminum-plastic film, especially thin aluminum-plastic film is more susceptible to damage. If the tension cannot be automatically adjusted, manual monitoring and parameter adjustment are required in real time, which increases the labor intensity and intervention frequency of operators, reduces the degree of automation, and easily leads to unqualified film rolls, increases scrap rate, and causes material waste and increased production costs.

[0004] Therefore, this utility model proposes a tension-adaptive aluminum-plastic film automatic winding control device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tension-adaptive automatic winding control device for aluminum-plastic film.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a tension-adaptive aluminum-plastic film automatic winding control device, including a base plate, and further comprising:

[0007] A winding assembly includes a support block connected to a base plate, a drive motor mounted on the support block, a rotating shaft connected to the output end of the drive motor, a first moving ring slidably connected to the rotating shaft, a second moving ring slidably connected to the side of the rotating shaft away from the first moving ring, a spring piece connected to both the first and second moving rings, one of the spring pieces connected to a fixed plate, a rotating rod rotatably connected to both the first and second moving rings, and a winding plate rotatably connected to the rotating rod.

[0008] Another spring is connected to an adjusting block, which is slidably connected to one end of the rotating shaft. A bolt is threaded onto the adjusting block, and the bolt is threaded onto the rotating shaft.

[0009] Furthermore, a guide rod is connected to one side of the support block.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the support block is fixed to the base plate to provide stable support for the drive motor and the rotating shaft. The guide rod is connected to one side of the support block. Its function is to provide precise guidance for the conveying of the aluminum-plastic film, ensure that the aluminum-plastic film maintains linear movement during the winding process, reduce offset and wrinkles, improve winding quality, and the surface of the guide rod is smoothed to reduce friction with the aluminum-plastic film and avoid scratching the surface of the film.

[0011] Furthermore, an auxiliary tension adaptive component is provided on the side of the base plate near the guide rod. The auxiliary tension adaptive component includes a first rotating block rotatably connected to the base plate, a moving block rotatably connected to the first rotating block, and a first limiting rod slidably connected within the moving block.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the first rotating block can rotate on the base plate, providing rotational freedom for the entire auxiliary tension adaptive assembly; the moving block is slidably connected through the first limiting rod; and the telescopic spring is connected between the moving blocks. When the tension of the aluminum-plastic film changes, the moving block can slide along the first limiting rod and compress or stretch the telescopic spring, thereby achieving initial buffering and adjustment of the tension.

[0013] Furthermore, a telescopic spring is provided on the first limiting rod, and the telescopic spring is connected to the moving block.

[0014] The beneficial effects of adopting the above-mentioned further scheme are: the telescopic spring plays a key role in the auxiliary tension self-adaptation process. When the tension of the aluminum-plastic film increases or decreases, the moving block is subjected to a pulling force and slides along the first limit rod to stretch or compress the telescopic spring, thereby maintaining the appropriate tension of the aluminum-plastic film and realizing adaptive adjustment.

[0015] Furthermore, a second rotating block is rotatably connected to the moving block, and a support plate is rotatably connected to the other end of the second rotating block. A guide roller is rotatably connected to the support plate.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the force exerted by the aluminum-plastic film on the guide roller is transmitted to the support plate, and the guide roller on the support plate is used to support and guide the aluminum-plastic film. When the moving block slides due to tension changes, the support plate drives the second rotating block to rotate around the moving block, thereby changing the position of the guide roller.

[0017] Furthermore, a second limiting rod is slidably connected inside the support plate, and the second limiting rod is connected to the base plate.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the second limiting rod is fixed on the base plate and slidably connected to the support plate. Its function is to limit the movement trajectory of the support plate and ensure that the guide roller maintains a stable movement direction during the tension adjustment process.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, before the winding process, the position of the adjusting block on the rotating shaft can be adjusted by rotating the bolt according to the winding requirements. When the drive motor starts, the output end drives the rotating shaft to rotate, thereby driving the winding assembly to start working. The aluminum-plastic film is wound on the winding plate, and the aluminum-plastic film exerts force on the winding plate. It also drives the moving ring to slide on the rotating shaft through the rotating rod. With the elastic force of the spring sheet, it can adaptively adjust the tension of the aluminum-plastic film during winding, avoiding the aluminum-plastic film from loosening or being overstretched. After winding is completed, the bolt is loosened, and the winding plate returns to its initial state under the action of the spring sheet, making it easy to take out the wound aluminum-plastic film roll.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-4 As shown, this embodiment provides a technical solution: a tension-adaptive aluminum-plastic film automatic winding control device, including a base plate 1, and further comprising:

[0032] The winding assembly 2 includes a support block 21 connected to the base plate 1. A drive motor 22 is mounted on the support block 21. The output end of the drive motor 22 is connected to a rotating shaft 23. A first moving ring 24 is slidably connected to the rotating shaft 23. A second moving ring 25 is slidably connected to the side of the rotating shaft 23 away from the first moving ring 24. Both the first moving ring 24 and the second moving ring 25 are connected to a spring piece 26. One of the spring pieces 26 is connected to a fixing plate 27. Both the first moving ring 24 and the second moving ring 25 are rotatably connected to a rotating rod 28. A winding plate 29 is rotatably connected to the rotating rod 28.

[0033] Another spring 26 is connected to an adjusting block 210, which is slidably connected to one end of the rotating shaft 23. A bolt 211 is threaded onto the adjusting block 210, which is threaded onto the rotating shaft 23. Before the winding process, the position of the adjusting block 210 on the rotating shaft 23 can be adjusted by rotating the bolt 211 according to the winding requirements. When the drive motor 22 starts, the output end drives the rotating shaft 23 to rotate, thereby driving the winding assembly 2 to start working. The aluminum-plastic film is wound on the winding plate 29. The aluminum-plastic film exerts force on the winding plate 29 and drives the moving ring to slide on the rotating shaft 23 through the rotating rod 28. With the elastic force of the spring 26, the tension of the aluminum-plastic film during winding is adaptively adjusted to avoid the aluminum-plastic film from loosening or being overstretched. After winding is completed, the bolt 211 is loosened, and the winding plate 29 returns to its initial state under the action of the spring 26, making it easy to take out the wound aluminum-plastic film roll.

[0034] The above solutions also have the problem that the aluminum-plastic film cannot meet the initial buffering and adaptive adjustment of tension when it is being wound up, such as... Figures 1-2As shown: A guide rod 212 is connected to one side of the support block 21. The support block 21 is fixed to the base plate 1 to provide stable support for the drive motor 22 and the rotating shaft 23. The guide rod 212 is connected to one side of the support block 21. Its function is to provide precise guidance for the conveying of the aluminum-plastic film, ensure that the aluminum-plastic film maintains a straight movement during the winding process, reduce deviation and wrinkles, and improve the winding quality. The surface of the guide rod 212 is smoothed to reduce the friction with the aluminum-plastic film and avoid scratching the surface of the film.

[0035] like Figure 1 as well as Figure 5 As shown, an auxiliary tension adaptive assembly 3 is provided on the side of the base plate 1 near the guide rod 212. The auxiliary tension adaptive assembly 3 includes a first rotating block 31 rotatably connected to the base plate 1, a moving block 33 rotatably connected to the first rotating block 31, and a first limiting rod 32 slidably connected inside the moving block 33. The first rotating block 31 can rotate on the base plate 1, providing rotational freedom for the entire auxiliary tension adaptive assembly 3. The moving block 33 is slidably connected through the first limiting rod 32. A telescopic spring 34 is connected between the moving blocks 33. When the tension of the aluminum-plastic film changes, the moving block 33 can slide along the first limiting rod 32 and compress or stretch the telescopic spring 34, thereby achieving initial buffering and adjustment of the tension. The first limiting rod 32 is provided with a telescopic spring 34, which is connected to the moving block 33. The telescopic spring 34 plays a key role in the auxiliary tension adaptive process. When the tension of the aluminum-plastic film increases or decreases, the moving block 33... 3. Under the action of tension, the film slides along the first limiting rod 32 and stretches or compresses the telescopic spring 34 to maintain the appropriate tension of the aluminum-plastic film and achieve adaptive adjustment. A second rotating block 35 is rotatably connected to the moving block 33. The other end of the second rotating block 35 is rotatably connected to the support plate 36. A guide roller 37 is rotatably connected to the support plate 36. The force exerted by the aluminum-plastic film on the guide roller 37 is transmitted to the support plate 36. The guide roller 37 on the support plate 36 is used to support and guide the aluminum-plastic film. When the moving block 33 slides due to tension changes, the support plate 36 drives the second rotating block 35 to rotate around the moving block 33, causing the position of the guide roller 37 to change. A second limiting rod 38 is slidably connected inside the support plate 36. The second limiting rod 38 is connected to the base plate 1 and fixed to the base plate 1 and slidably connected to the support plate 36. Its function is to limit the movement trajectory of the support plate 36 and ensure that the guide roller 37 maintains a stable movement direction during tension adjustment.

[0036] Working principle:

[0037] like Figures 1-5As shown, before the equipment starts, initial adjustments are made according to the winding requirements of the aluminum-plastic film. The operator rotates bolt 211. Since bolt 211 is threadedly connected to shaft 23, rotation will cause adjusting block 210 to slide on shaft 23. The movement of adjusting block 210 is transmitted to winding plate 29 through spring 26, adjusting winding plate 29 to a suitable initial position to prepare for subsequent winding. When the equipment is running, drive motor 22 starts, and its output end drives shaft 23 to rotate, causing aluminum-plastic film to wrap around winding plate 29. When the tension of aluminum-plastic film changes, guide roller 37 will first be subjected to a corresponding force. This force is transmitted through support plate 36, causing moving block 33 to slide on first limit rod 32. The sliding of moving block 33 will compress or stretch telescopic spring 34, using the elastic deformation of telescopic spring 34 to buffer and adjust tension. At the same time, support plate 36 slides on second limit rod 38 to ensure that guide roller 37 maintains a stable direction of movement during tension adjustment, thus initially adjusting the tension of aluminum-plastic film. After buffering and adjustment, the aluminum-plastic film maintains a straight-line movement under the action of the guide rod 212, reducing offset and wrinkles and improving the winding quality. During the winding process, the tension change of the aluminum-plastic film will apply a certain force to the winding plate 29. This force is transmitted through the rotating rod 28, which drives the first moving ring 24 and the second moving ring 25 to slide on the rotating shaft 23. Due to the elastic force of the spring piece 26, when the tension of the aluminum-plastic film changes, the moving ring will slide accordingly, realizing adaptive adjustment of the tension during the winding of the aluminum-plastic film. When the tension is too large, the moving ring slides and compresses the spring piece 26 to buffer the excessive tension and avoid excessive stretching of the aluminum-plastic film. When the tension is too small, the elastic force of the spring piece 26 pushes the moving ring to slide, so that the aluminum-plastic film maintains appropriate tension and prevents slack. After the winding is completed, the bolt 211 is loosened, and the adjusting block 210 is no longer restricted by the bolt 211. Under the action of the elastic force of the spring piece 26, the winding plate 29 returns to the initial state. At this time, the wound aluminum-plastic film roll can be easily taken out from the winding plate 29.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
