Description

Technical Field

[0001] This utility model relates to the technical field of paper product processing machinery, and in particular to an automatic tensioning device for the paper folding section of a production line. Background Technology

[0002] As is well known, in modern industrial production, especially in industries such as printing and packaging that require handling paper or other flexible materials, continuous paper folding lines play a crucial role. These machines typically contain a series of complex mechanical structures to complete a series of processes from material feeding to finished product output. However, the quality of paper transport directly affects the quality of the final product. Therefore, ensuring the stability of paper throughout the entire transport process has become key to improving production efficiency and product quality.

[0003] Traditional tensioning devices often employ manual adjustment or adaptive adjustment based on mechanical principles, such as using weights and springs to provide constant tension. While this approach can address paper slack to some extent, it struggles to monitor paper tension in real-time when faced with high-speed, high-precision modern production equipment. This means that operators cannot receive timely feedback and make corresponding adjustments when paper thickness changes or running speed fluctuates, potentially leading to paper wrinkles and tears. Furthermore, the ideal tension value varies for different paper materials and thicknesses, while traditional devices typically only provide a relatively fixed tension range, failing to make optimal adjustments for each material. When paper is suddenly subjected to external impacts during transport, such as the moment the paper roll starts or stops, traditional devices lack an effective buffering mechanism, which can not only damage the paper but also cause wear and tear on the equipment. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic tensioning device for the folding section of a linkage line, including a slide rail, a fixed box and an installation mechanism on the slide rail, an assembly mechanism between the fixed box and the slide rail, a fastening cylinder on the fixed box, a telescopic device at one end of the fastening cylinder, a fastening hole at the other end of the fastening cylinder, an adjusting column on the fastening hole, a push plate at one end of the telescopic device, an adjusting plate between the adjusting column and the interior of the fastening cylinder, a pressure sensor between the adjusting plate and the adjusting column, a compression spring between the adjusting plate and the push plate, a slider between one end of the telescopic device and one end of the adjusting column and the slide rail, a bearing seat on the slider, and a tensioning roller on the bearing seat.

[0005] The present invention discloses an automatic tensioning device for the folding section of a linkage line. The assembly mechanism includes an assembly groove and positioning holes. The assembly groove is opened at the bottom end of the fixed box. The slide rail passes through the assembly groove. A screw hole is opened between the assembly groove and one side of the fixed box. A threaded post is provided on the screw hole. The positioning holes are opened on one side of the slide rail. Multiple positioning holes are provided and arranged in an array.

[0006] The present invention relates to an automatic tensioning device for the folding section of a linkage line. The mounting mechanism includes mounting holes, which are formed at the bottom end of the slide rail, and multiple mounting holes are provided.

[0007] The present invention relates to an automatic tensioning device for the paper folding section of a linkage line, wherein the telescopic device is an electric telescopic rod.

[0008] The automatic tensioning device for the paper folding section of the linkage line of this utility model uses an alloy spring as the compression spring.

[0009] The present invention relates to an automatic tensioning device for the paper folding section of a linkage line, wherein the push plate and the adjusting plate are both adapted to the inner wall of the fastening cylinder.

[0010] The automatic tensioning device for the paper folding section of the linkage line of this utility model has a sealed bearing housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The pressure sensor set between the adjusting plate and the adjusting column can collect the force data between the two tension rollers in real time, thereby reflecting the current tension of the paper. This signal can be connected to the equipment control system to form a closed-loop feedback mechanism. When the tension is detected to be lower or higher than the set threshold, the system can immediately control the telescopic device to achieve automatic adjustment, avoiding the traditional method of relying on human experience and manual adjustment, and improving the automation and intelligence level of the production line. Through the telescopic movement of the telescopic device, the push plate is pushed and the compression spring is compressed and released, which drives the adjusting plate and the adjusting column to move, thereby changing the position of the tension roller. When the paper tension decreases, the telescopic device extends to widen the distance between the two rollers; conversely, it shortens the distance to maintain constant tension and ensure stable paper transmission. This structure can flexibly cope with different types and thicknesses of paper, and can also adapt to various production rhythms such as high speed and low speed. It has a wide range of applications. When the paper shakes, jams, or tension fluctuations occur during the process of paper running, the compression spring can effectively absorb the impact energy. Attached Figure Description

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] like Figures 1 to 4 As shown, this utility model is an automatic tensioning device for the folding section of a linkage line, including a slide rail 1, a fixed box 2 and an installation mechanism on the slide rail 1, an assembly mechanism between the fixed box 2 and the slide rail 1, a fastening cylinder 3 on the fixed box 2, a telescopic device 4 at one end of the fastening cylinder 3, a fastening hole at the other end of the fastening cylinder 3, an adjusting post 5 on the fastening hole, a push plate 6 at one end of the telescopic device 4, an adjusting plate 7 between the adjusting post 5 and the interior of the fastening cylinder 3, a pressure sensor 8 between the adjusting plate 7 and the adjusting post 5, and a compression spring 9 between the adjusting plate 7 and the push plate 6. 4 and one end of the adjusting column 5 are provided with a slider 10 between them and the slide rail 1. The slider 10 is provided with a bearing seat 11, and the bearing seat 11 is provided with a tension roller 12. In this embodiment, the pressure sensor 8 set between the adjusting plate 7 and the adjusting column 5 can collect the force data between the two tension rollers 12 in real time, thereby reflecting the current tension of the paper. This signal can be connected to the equipment control system to form a closed-loop feedback mechanism. When the tension is detected to be lower or higher than the set threshold, the system can immediately control the telescopic device 4 to move, realize automatic adjustment, avoid the traditional method of relying on human experience judgment and manual adjustment, and improve the automation and intelligence level of the production line.

[0019] This utility model discloses an automatic tensioning device for the folding section of a linkage line. To facilitate flexible adjustment of the installation position of the fixed box 2 on the slide rail 1, the assembly mechanism includes an assembly groove and positioning holes 13. The assembly groove is located at the bottom of the fixed box 2, and the slide rail 1 passes through the assembly groove. A screw hole is provided between the assembly groove and one side of the fixed box 2, and a threaded post 14 is provided on the screw hole. Multiple positioning holes 13 are located on one side of the slide rail 1 and arranged in an array. The assembly groove allows the fixed box 2 to slide on the slide rail 1. The array of multiple positioning holes 13 makes it easy to move the fixed box 2 to the nearest positioning hole 13 within a specified position range and align it with the screw hole. Then, the threaded post 14 is threaded into the screw hole and abuts against the positioning hole 13, thereby locking the fixed box 2. This allows for rapid adjustment of the position of the assembled fixed box 2.

[0020] The automatic tensioning device for the paper folding section of the linkage line of this utility model, in order to facilitate the installation of the slide rail 1 on the equipment, the installation mechanism in this solution includes mounting holes 15, which are opened at the bottom end of the slide rail 1. There are multiple mounting holes 15, and personnel can use bolts or other parts to easily assemble the slide rail 1 on the equipment through the multiple mounting holes 15.

[0021] In order to improve the tension control accuracy, the automatic tensioning device for the paper folding section of the linkage line of this utility model is an electric telescopic rod. The electric telescopic rod can achieve high-precision adjustment and telescopic movement accuracy, thereby improving the tension control accuracy.

[0022] In order to improve the service life of the compression spring 9, the automatic tensioning device for the paper folding section of the linkage line of this utility model adopts an alloy spring material for the compression spring 9. Alloy springs have the characteristics of long service life and good elastic support, which can further improve the shock absorption effect when the paper shakes instantaneously.

[0023] In order to improve the movement stability of the push plate 6 and the adjusting plate 7 on the inner wall of the fastening cylinder 3, the automatic tensioning device for the paper folding part of the linkage line of this utility model is designed such that the push plate 6 and the adjusting plate 7 are adapted to the inner wall of the fastening cylinder 3. By adapting the adjusting plate 7 and the push plate 6 to the inner wall of the fastening cylinder 3, the adjusting plate 7 and the push plate 6 can slide more stably in a straight line on the inner wall of the fastening cylinder 3.

[0024] In order to reduce the entry of external impurities and dust into the bearing seat 11, the automatic tensioning device for the paper folding section of the linkage line of this utility model is a sealed bearing. By using a sealed bearing, the bearing seat 11 can have excellent dustproof performance, thereby reducing the entry of impurities and dust, and thus adding beneficial effects.

[0025] This utility model discloses an automatic tensioning device for the paper folding section of a continuous production line. During operation, a slide rail 1 is installed on the paper folding section equipment via an installation mechanism. The installation method of the installation mechanism is a common method in the prior art and will not be described in detail here. A fixing box 2 is assembled and positioned on the slide rail 1 via an assembly mechanism. Then, the paper passes through two tensioning rollers 12. The pressure sensor 8 between the adjusting plate 7 and the adjusting column 5 can detect the force between one tensioning roller 12 and the other, thereby determining the tension of the paper. When the pressure value is low, the extension device 4 is used to extend the extension mechanism, thereby causing the push plate 6 to move. The compression spring 9 and the adjusting plate 7 move, thereby causing the adjusting column 5 to drive the slider 10 at one end to move. The telescopic device 4 moves in the fastening cylinder 3 and drives the slider 10 at one end of the telescopic device 4 to move, thereby causing the two sliders 10 to slide linearly on the slide rail 1, thereby increasing the distance between the two tension rollers 12. When the pressure value is large, the output end of the telescopic device 4 is controlled to contract and move, and the distance between the two tension rollers 12 is shortened. The compression spring 9 can absorb the impact when the paper shakes instantaneously, preventing the equipment from jamming or the paper from tearing. The pressure sensor 8 detects the pressure value in real time, and the tension can be adjusted in real time according to the value.

[0026] The automatic tensioning device for the folding section of the linkage line of this utility model can be installed, connected, or set in a common mechanical manner. Any method that can achieve its beneficial effect can be implemented. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
