Description

Technical Field

[0001] This invention relates to the technical field of paper winding equipment, and in particular to a paper winding device. Background Technology

[0002] In the entire industrial process of paper handling and printing, the meticulous flattening and smoothing of paper is not a dispensable step, but a cornerstone step that lays the foundation for all subsequent high-quality work. This crucial pretreatment operation aims to completely eliminate any curling, wrinkling, wavy or unevenness that may occur in the paper during production, transportation or storage, thereby giving the paper an ideal and uniform physical form.

[0003] By ensuring the paper surface achieves ultimate flatness and uniformity, it significantly improves the accuracy and efficiency of all subsequent processing stages. Whether it's precise cutting, creasing, accurate folding, or smooth binding, it greatly reduces the occurrence of paper jams, misalignments, dimensional deviations, and other defects, thereby ensuring the smooth and efficient operation of the entire production chain and effectively reducing production losses.

[0004] Traditional paper flattening methods rely primarily on rollers on fixed tracks to simply unfold and flatten the paper. While this method is simple and direct, it struggles to effectively control and flatten paper with complex shapes or materials. Furthermore, due to limitations in the equipment's structure, it is difficult to precisely intervene and correct subtle twists and wrinkles that occur during the flattening process. Summary of the Invention

[0005] This application provides a paper rolling device that can precisely intervene in and correct the minute twists and wrinkles of paper during the flattening process.

[0006] This application provides a paper winding device, which adopts the following technical solution: A paper rolling device includes a support frame, a drive motor mounted on the support frame, and an air shaft driven by the drive motor. The support frame is provided with a positioning frame, and the positioning frame is provided with at least two flattening rollers. The flattening rollers are staggered to form an S-shaped path for the paper to pass through. A diagonal support is provided on one side of the positioning frame, and a swing arm is rotatably connected to the diagonal support. A guide shaft is provided at the end of the swing arm. The guide shaft is staggered with the flattening rollers and a limiting channel is formed between them. The output end of an electric push rod is hinged to the middle of the swing arm. A fixed shaft is also provided on the diagonal support, and a correction component is provided between the fixed shaft and the guide shaft.

[0007] Preferably, the positioning frame includes two parallel columns, each column having an adjustment groove. The flattening roller is slidably installed at both ends within the adjustment grooves of the two columns. The adjustment grooves include horizontally distributed adjustment grooves and vertically distributed adjustment grooves.

[0008] Preferably, the guide shaft is disposed above the fixed shaft, and the top of the fixed shaft is provided with a guide groove. The guide groove is provided with a pneumatic control component, which includes a miniature jet nozzle, an ultrasonic generator, and a micro-pressure sensor. The miniature jet nozzle can independently adjust its angle and pressure.

[0009] Preferably, the correction assembly includes two correction blocks arranged opposite each other along the width direction of the paper. The correction blocks are slidably disposed in a groove of a fixed shaft. A lead screw assembly is provided in the groove to synchronously drive the two correction blocks to move towards or away from each other.

[0010] Preferably, the inner wall of the guide groove of the pneumatic control component is provided with a plurality of guide plates, which are arranged around the micro jet nozzle to guide the airflow to be concentrated and sprayed onto the paper wrinkle area.

[0011] Preferably, the jet direction of the micro-jet nozzle forms an acute angle with the paper surface, the ultrasonic generator is signal-connected to the micro-jet nozzle controller, and the detection surface of the micro-pressure sensor is set in contact with the paper surface.

[0012] Preferably, the inner side of the correction block is provided with a rotatable mounting shaft, the mounting shaft is connected to the output end of the drive motor through a connecting rod, the middle part of the connecting rod is connected to the output end of the drive motor, and the drive motor is fixed to the inner side of the correction block.

[0013] Preferably, the output wheel of the drive motor is connected to the drive shaft via a belt, and both ends of the drive shaft are supported in bearing seats at the top of the support frame by rolling bearings. The drive shaft and the air expansion shaft are coaxially connected via a flange.

[0014] Preferably, a photoelectric sensor is provided inside the groove of the fixed shaft, and the photoelectric sensor is signal-connected to the drive end of the lead screw assembly.

[0015] Preferably, the two ends of the connecting rod are pivotally connected to two mounting shafts respectively. When the drive motor rotates, it drives the connecting rod to rotate around its central pivot point. The rotation axis of the mounting shaft is perpendicular to the direction of paper movement.

[0016] In summary, this application has the following beneficial effects: 1. By setting horizontally and vertically distributed adjustment grooves on the column, the sliding adjustment of the two flattening rollers in the horizontal and vertical directions can be realized. The combination of the horizontal and vertical adjustment capabilities of the two flattening rollers means that the bending path, force and contact point of the paper when passing through the flattening area can be controlled with extreme precision and flexibility; this high degree of adjustability is the key to achieving efficient flattening.

[0017] 2. By using the ultrasonic feedback of the wrinkle position and the stress distribution feedback of the micro-pressure sensor in the pneumatic control component, a precise airflow is locally injected. The micro-jet nozzles press to smooth out micro-wrinkles or guide the paper to be evenly stressed, thereby enabling non-contact intervention and correction of defects before the paper enters the winding point or during the winding process.

[0018] 3. When the pneumatic control component is in operation, the relative movement of the two correction blocks enables physical correction of the paper. At the same time, the rotation of the mounting shaft and the drive of the connecting rod reduce damage to the paper edges and adjust the pressure applied to the paper by the mounting shaft.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0021] This invention discloses a paper winding device, such as... Figure 1As shown, the device includes a support frame 1, a drive motor 2, and a motor mounting plate 3 mounted on the support frame 1 for fixing the drive motor 2. Two bearing seats 4 are fixedly installed on the top of the support frame 1. Rolling bearings 5 ​​are installed inside the bearing seats 4. A drive shaft 6 is installed inside the rolling bearings 5. The drive shaft 6 is connected to the output wheel of the drive motor 2 via a belt 7. The drive motor 2 causes the drive shaft 6 to rotate under the action of the belt 7. An air expansion shaft 8 is coaxially connected to the shaft end of the drive shaft 6 via a flange 9. The air expansion shaft 8 is used to fix the core tube and realize the winding function.

[0022] like Figure 1 As shown, drive motor 2 starts, and its output wheel begins to rotate. The output wheel of drive motor 2 is connected to the pulley of drive shaft 6 via belt 7, transmitting the rotational power of drive motor 2 to drive shaft 6. Belt 7 drive has advantages such as smooth operation, low noise, and overload protection.

[0023] like Figure 1 As shown, specifically, the drive shaft 6 is mounted in two bearing housings 4, each containing rolling bearings 5. The rolling bearings 5 ​​reduce friction during the rotation of the drive shaft 6, ensuring smooth and efficient rotation. One end of the drive shaft 6 is coaxially connected to the air shaft 8 via a flange 9. This means that when the drive shaft 6 rotates, the air shaft 8 rotates synchronously. Before winding, the core of the material to be wound is placed on the air shaft 8 in its contracted state.

[0024] like Figure 1 As shown, air is then introduced into the air shaft 8. After inflation, the air shaft 8 expands outward, tightly gripping the inner wall of the paper tube and firmly fixing the paper tube to the air shaft 8, ensuring that the roll will not slip during rotation. As the air shaft 8 and the paper tube fixed to it rotate, the paper material is evenly and tightly wound onto the paper tube, completing the winding process.

[0025] like Figure 1 As shown, after winding is completed, the gas inside the air expansion shaft 8 is released, and the air expansion shaft 8 will contract, at which point the rolled material can be easily and quickly removed.

[0026] like Figure 1As shown, the air expansion shaft 8 uses air pressure expansion to evenly fix the drum, ensuring no gap between the drum and the air expansion shaft 8, thereby achieving high concentricity winding and preventing material vibration or skewing during winding, thus guaranteeing the quality of winding. Compared to traditional mechanical clamping methods, the loading and unloading process of the drum using the air expansion shaft 8 is extremely simple and quick, requiring only inflation and deflation to fix and loosen, greatly reducing downtime and improving production efficiency. The air expansion shaft 8 uses uniform air pressure expansion to tighten the drum, avoiding localized stress concentration or damage to the inner wall of the drum that may be caused by mechanical clamps, making it particularly suitable for applications with high requirements for drum quality.

[0027] like Figure 1 As shown, the drive motor 2 is adjusted to a constant torque mode. If it were adjusted to a constant speed mode, any difference in production speed could easily lead to paper breakage or motor overheating and damage. The constant torque mode ensures that the paper maintains tension during winding, resulting in more uniform paper curling. The paper tube is fitted onto the air expansion shaft 8. During use, air can be injected into the air expansion shaft 8 to achieve and maintain a constant air pressure, causing the surface of the air expansion shaft 8 to swell, increasing friction with the inner wall of the paper tube, and achieving synchronous rotation of angular velocity.

[0028] like Figure 1 and Figure 2 As shown, a positioning frame 10 is fixedly installed on one side of the support frame 1. Two parallel columns 11 are fixedly installed on the positioning frame 10. The positioning frame 10 is located on the same side as the air shaft 8, and a flattening roller 12 is provided between the two columns 11 of the positioning frame 10. There are two flattening rollers 12 arranged vertically. The paper passes through the surfaces of the two flattening rollers 12 alternately. The paper does not simply pass over or under one flattening roller 12, but rather passes through the surfaces of the two flattening rollers 12 alternately. This means that the paper will first wrap around a portion of the curvature of one roller, and then wrap around another portion of the curvature of the other roller in the opposite direction, forming an "S" path. The paper is subjected to tension in the alternate path and forms a certain contact curvature on the surface of the roller, so that the paper is slightly stretched and flattened laterally. Any wrinkles, creases, or wavy deformations that may occur during the paper feeding process will be effectively flattened under the alternating action and tension of the flattening rollers 12.

[0029] like Figure 2As shown, specifically, two flattening rollers 12 are spaced apart and installed in the adjustment slots 13 of the columns 11 on the positioning frame 10. One column 11 has a horizontally distributed adjustment slot 13, and the other column 11 has a vertically distributed adjustment slot 13, which is used to realize the sliding adjustment of the two flattening rollers 12 in the horizontal and vertical directions. At the same time, the two flattening rollers 12 can also be used in conjunction with each other. When the paper enters from above the upper flattening roller 12 and rolls out below the lower flattening roller 12, forming an "S" shaped cross section, the paper will undergo a continuous, bidirectional bending and reverse bending process. This "S" shaped bending forces the paper fibers to be stretched and compressed in different directions, thereby effectively destroying and releasing the stress memory inside the paper; that is, the internal stress that causes the paper to curl or deform.

[0030] like Figure 2 and Figure 3 As shown, a diagonal support bracket 14 is fixedly installed on one side of the positioning frame 10. A rotatable swing arm 15 is provided on the diagonal support bracket 14. One end of the swing arm 15 is hinged to the diagonal support bracket 14, and a fixed shaft 16 is fixedly installed on the other end of the swing arm 15. A connecting seat 17 is fixedly installed at the top tangent of the fixed shaft 16. A rotatable guide shaft 18 is provided on the connecting seat 17. The guide shaft 18 is located on one side of the flattening roller 12 and is offset from the two flattening rollers 12. Moreover, a limiting channel for paper to pass through is formed between the lower surface of the guide shaft 18 and the upper surface of the fixed shaft 16 to prevent it from jumping up and down or deviating from the preset path. By rotating the angle of the swing arm 15, the guide shaft 18 at the end of the swing arm 15 is adjusted to a suitable height, and the lower surface of the guide shaft 18 is controlled to contact the upper surface of the paper. By adjusting the swing arm 15, the guide shaft 18 is slightly pressed against the upper surface of the paper. Since the guide shaft 18 is rotatable, when it comes into contact with the paper surface, it can adapt to the movement of the paper by rotating itself, reducing frictional resistance, ensuring that the paper passes through smoothly, and avoiding scratches or damage to the paper surface.

[0031] like Figure 3 and Figure 4 As shown, a positioning platform 19 is provided on the inclined support bracket 14, and an electric push rod 20 is rotatably connected to the positioning platform 19. The output end of the electric push rod 20 is hinged to the middle of the swing rod 15. Through the electric push rod 20, the swing rod 15 is rotated around the hinge point of the inclined support bracket 14, thereby realizing the driving effect of the swing rod 15.

[0032] like Figure 3 and Figure 4 As shown, a guide groove 21 is provided at the top cross-section of the fixed shaft 16. The guide groove 21 is equipped with a pneumatic control component, which includes multiple micro air nozzles with independently adjustable angle and pressure, an ultrasonic generator, and a micro pressure sensor located at the cross-section of the lower surface of the guide shaft 18.

[0033] like Figure 3 and Figure 4 As shown, the inner wall of the guide groove 21 of the air control component is provided with several guide plates. The guide plates are arranged around the micro jet nozzles to guide the airflow to be concentrated and sprayed onto the paper wrinkle area. The micro jet nozzle array is distributed in a matrix and the spacing is less than 5 mm.

[0034] like Figure 3 and Figure 4 As shown, specifically, ultrasonic technology is used to scan the paper surface in real time. When the paper wrinkles, the reflection characteristics of the ultrasonic waves change, and the system analyzes these changes to accurately identify the location, size, and shape of the wrinkles.

[0035] like Figure 3 and Figure 4 As shown, a micro-pressure sensor installed on the lower surface of the guide shaft 18 monitors the stress distribution of the paper in real time when it comes into contact with the guide shaft 18. By analyzing this stress data, the system can determine whether the paper is subjected to uniform stress, whether there is excessive or insufficient local tension, and thus predict or detect potential deformation caused by stress concentration.

[0036] like Figure 3 and Figure 4 As shown, after receiving the wrinkle location data from ultrasonic feedback and the stress distribution data from the micro-pressure sensor, the system performs rapid analysis. Based on the analysis results, the system accurately calculates the location, angle, and pressure of the airflow to be applied. According to the decision, the system precisely controls the corresponding micro-nozzle to eject a highly concentrated airflow at a specific location, angle, and pressure.

[0037] like Figure 3 and Figure 4 As shown, this precise airflow exerts a localized impact on the paper surface through its momentum and pressure. The airflow directly impacts the wrinkled or raised areas, smoothing them out. Furthermore, the airflow can guide the paper to move slightly in a specific direction or apply pressure locally, thereby redistributing stress, making the paper more evenly stressed, preventing new wrinkles from forming, or correcting the paper's trajectory. The entire process continues before the paper enters the winding point or during winding, enabling real-time, dynamic, and non-contact intervention and correction of defects.

[0038] like Figure 3 and Figure 4As shown, by combining ultrasonic and micro-pressure sensors, the system can accurately identify defect locations and stress distributions, applying precise airflow only to the localized areas requiring intervention. This "point-to-point" intervention method is more efficient and energy-saving than traditional "area" adjustments, and avoids over-intervention in non-defective areas. Real-time data provided by sensors allows the system to respond instantly to changes in paper condition. Whether it's fluctuations in production speed, minor changes in material properties, or sudden defects, the system can quickly adjust, ensuring continuous and stable problem correction, improving production stability and reliability. By promptly smoothing wrinkles, correcting uneven stress, and guiding the paper to uniform stress, the system significantly improves the flatness, tightness, and overall quality of the wound products. This reduces scrap rates and rework caused by defects such as wrinkles and deformation, thereby lowering production costs.

[0039] like Figure 3 and Figure 4 As shown, a photoelectric sensor is provided on the fixed shaft 16 for real-time monitoring of the actual position of the paper on the guide shaft 18. A groove 22 is provided on one side of the fixed shaft 16 along its axial direction. Two opposing correction blocks 23 are provided in the groove 22 of the fixed shaft 16. The correction blocks 23 are located at two opposite edges of the paper. The groove 22 of the fixed shaft 16 is provided with a lead screw assembly for synchronously driving the correction blocks 23. Through the lead screw assembly, the relative movement of the two correction blocks 23 is adjusted so that their movement trajectories are relatively synchronously close and far away, thereby realizing the correction function of the paper.

[0040] like Figure 3 and Figure 4 As shown, a photoelectric sensor detects the actual position of the paper in the axial direction in real time and compares it with a preset ideal center position to determine whether there is a deviation and the direction and magnitude of the deviation. When the paper deviates from the center, the system issues a command. The lead screw assembly rotates under the drive of the motor, and the lead characteristic of the lead screw's bidirectional thread is used to convert the rotational motion into the linear motion of the correction block 23. This ensures that the two correction blocks 23 can move closer to or away from the center line of the paper at the same speed and distance. When the paper deviates, for example, to the left, the system drives the correction block 23 and the micro-air nozzle to move slightly closer to the center, pushing the paper back to the preset center line by applying gentle and symmetrical pressure to the edge of the paper. If the paper is too far to the right, the correction block 23 will move slightly away, allowing the paper to move to the left to reach the center.

[0041] like Figure 3 and Figure 4As shown, a drive motor is fixedly mounted on the inner side of the correction block 23. A connecting rod 24 is connected to the output end of the drive motor, and the middle of the connecting rod 24 is connected to the output end of the drive motor. Two rotatable mounting shafts 25 are provided at both ends of the connecting rod 24. When the edge of the paper contacts these mounting shafts 25, the friction between the paper and the mounting shafts 25 changes from sliding friction to rolling friction due to the rolling motion of the mounting shafts 25. Rolling friction is much less than sliding friction, thus greatly reducing the resistance experienced by the paper during the correction process. This reduction in friction directly leads to a decrease in wear, scratches, and tears on the paper edges, especially for thin paper, coated paper, or paper with a fragile fiber structure; this protective effect is particularly significant.

[0042] like Figure 3 and Figure 4 As shown, when the drive motor rotates, it causes the connecting rod 24 to rotate around its central fulcrum. As the connecting rod 24 rotates, the vertical distance or angle of action of its two mounting shafts 25 relative to the paper changes. This change in geometric position directly affects the positive force applied by the mounting shafts 25 to the paper. For example, if the rotation of the connecting rod 24 brings the mounting shafts 25 closer to or more tightly against the paper, the applied pressure increases; conversely, if the rotation moves the mounting shafts 25 slightly away from or loosens them, the applied pressure decreases. By precisely controlling the rotation direction and angle of the drive motor, precise control of the rotation amplitude of the connecting rod 24 can be achieved, thereby enabling fine adjustment of the pressure applied to the paper by the mounting shafts 25.

[0043] like Figure 3 and Figure 4 As shown, the rolling friction design significantly reduces wear, scratches, and deformation of the paper edges during transport, improving product quality, especially for printed materials or finished products with high appearance requirements. By precisely adjusting the pressure applied to the paper by the mounting shaft 25, it is ensured that the paper is stably clamped and guided during transport, reducing jitter and deviation, thereby improving the stability of paper transport and the accuracy of deviation correction.

[0044] like Figure 3 and Figure 4 As shown, the rolling setting of the mounting shaft 25 can reduce friction and damage to the paper edges while limiting the paper's travel path during the correction process. In addition, the connecting rod 24 is rotated by the drive motor, thereby adjusting the pressure applied to the paper by the mounting shaft 25.

[0045] Working principle: The operator first places the core tube onto the air shaft 8 and inflates the air shaft 8. After inflation, the air shaft 8 expands outward, thus tightly gripping the inner wall of the paper tube and firmly fixing the paper tube to the air shaft 8, ensuring that the roll will not slip when rotating.

[0046] Then, one end of the paper is passed through the mounting shaft 25, the guide shaft 18, the flattening roller 12 in sequence and finally fixed on the core tube. Subsequently, the drive motor 2 is started, causing the air shaft 8 to rotate, so as to realize the rotation of the core tube and the winding of the paper.

[0047] During the paper winding process, the ultrasonic feedback of the wrinkle position and the stress distribution feedback of the micro-pressure sensor in the pneumatic control component are used to locally spray precise airflow. The micro-jet nozzles are used to smooth out micro-wrinkles or guide the paper to be evenly stressed, so as to intervene and correct defects in a non-contact manner before the paper enters the winding point or during the winding process.

[0048] When the pneumatic control component is in operation, the relative movement of the two correction blocks 23 enables physical correction of the paper. At the same time, the rotation of the mounting shaft 25 and the drive of the connecting rod 24 reduce damage to the paper edges and adjust the pressure applied to the paper by the mounting shaft 25.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
