Description

Technical Field

[0001] This utility model relates to the field of rewinding equipment technology, and in particular to a rewinding device that avoids indentations. Background Technology

[0002] Rewinding machines are generally used for rewinding and slitting mica tape, paper, and film, serving to cut them in half. They are often used to slit wide rolls of material and play an important role in subsequent re-slitting. They are a special equipment for paper, mica tape, and film.

[0003] When rewinding paper or film, excessive tension may occur, resulting in indentations. Therefore, manual observation is required during the rewinding process to address any indentations. If the paper or film is large, manual observation may not be sufficient to detect indentations in time, and the rewinding effect needs improvement.

[0004] To address this, we propose a rewinding device that avoids indentations. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a rewinding device that avoids indentation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rewinding device that avoids indentation, comprising a fixed frame, a rewinding roller rotatably mounted on the fixed frame, a tension roller movably mounted on the fixed frame, a cross frame fixedly mounted on the fixed frame, a mounting seat slidably mounted on the cross frame, an industrial camera fixedly mounted at the bottom of the mounting seat, and a drive triggering component provided on the cross frame.

[0007] The drive triggering component includes a movable base, which is slidably mounted on a crossbeam. A drive gear is movably mounted on one side of the movable base. A lower extension frame is fixedly mounted on the crossbeam. A rack is fixedly mounted on the lower extension frame. A touch block and a trigger switch are provided on the lower extension frame.

[0008] Preferably, mounting brackets are symmetrically fixedly installed on the fixed frame, and lifting blocks are movably installed on the mounting brackets.

[0009] Preferably, the tension roller is rotatably mounted between two lifting blocks, and an electric cylinder is fixedly mounted on the mounting frame, with the lifting blocks being driven to rise and fall by the electric cylinder.

[0010] Preferably, the drive trigger assembly further includes a connecting frame, which is fixedly mounted on one side of the movable base, and the drive gear is rotatably mounted on the connecting frame, with the drive gear meshing with the rack.

[0011] Preferably, the lower extension frame has grooves evenly distributed, the trigger switch is fixedly installed inside the groove, and the contact block is slidably installed inside the groove.

[0012] Preferably, the drive trigger assembly further includes a spring, which is fixedly installed inside the groove, and the contact block is fixedly connected to one end of the spring.

[0013] This invention provides a rewinding device to avoid indentations. Compared with the prior art, it has the following improvements and advantages: By incorporating an industrial camera and a drive triggering component, when the industrial camera captures images of paper and film, the drive gear rotates and meshes with the rack, driving the industrial camera to move at a constant speed above the paper and film rewinding area. Simultaneously, during the uniform lateral movement of the industrial camera, the drive gear meshes with the rack, and the toothed blocks on the drive gear contact the pressure block, triggering the corresponding trigger switch. When the trigger switch is pressed, the industrial camera captures an image once. During the uniform lateral movement of the industrial camera, multiple image captures are performed at intervals to expand the image acquisition range, ensuring that the paper and film rewinding area is completely covered and detected. The captured images are transmitted to a vision inspection system for processing, analysis, and comparison to reflect whether indentations have occurred on the paper and film. The tension of the paper and film is adjusted based on the presence of indentations to prevent continuous indentation and improve the rewinding effect. Attached Figure Description

[0021] 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.

[0022] A rewinding device that avoids indentation, such as Figure 1 - Figure 4As shown, the system includes a fixed frame 1, on which a rewinding roller 2 is rotatably mounted. The rewinding roller 2 can rewind paper, film, etc. A tension roller 3 is movably mounted on the fixed frame 1, which can adjust the tension of the paper or film during rewinding. A mounting frame 4 is symmetrically fixed on the fixed frame 1, and a lifting block is movably mounted on the mounting frame 4. The tension roller 3 is rotatably mounted between the two lifting blocks. An electric cylinder is fixedly mounted on the mounting frame 4, and the lifting blocks are driven to rise and fall by the electric cylinder, which is electrically connected to an external controller. A crossbeam 5 is fixedly mounted on the fixed frame 1, and a mounting base 7 is slidably mounted on the crossbeam 5. An industrial camera 8 is fixedly mounted at the bottom of the mounting base 7. The industrial camera 8 can acquire images of the paper or film during rewinding. The acquired images are transmitted to a vision inspection system, which performs preprocessing and feature extraction on the acquired images. Based on the extracted features, the system compares them with a standard image of the paper or film when no indentations appear and outputs the analysis results. To detect whether indentations occur during paper and film rewinding, a drive triggering component is installed on the crossbeam 5. This component drives the industrial camera 8 to perform intermittent image acquisition operations on the upper side of the paper and film rewinding area. By installing the industrial camera 8 and the drive triggering component, images can be acquired during paper and film rewinding. During image acquisition, the drive triggering component drives the industrial camera 8 to perform intermittent image acquisition operations on the upper side of the paper and film rewinding area to ensure that the area is covered during rewinding. Simultaneously, the acquired images are transmitted to a vision inspection system for processing, analysis, and comparison to detect whether indentations have occurred. Based on the presence of indentations, the height of the tension roller 3 is adjusted to regulate the tension of the paper and film, preventing excessive tension that could lead to indentations.

[0023] Furthermore, the drive triggering component includes a movable base 6, which is slidably mounted on a crossbeam 5. A lower extension frame 11 is fixedly mounted on the crossbeam 5, and a rack 12 is fixedly mounted on the lower extension frame 11. A connecting frame 9 is fixedly mounted on one side of the movable base 6, and a drive gear 10 is rotatably mounted on the connecting frame 9. The drive gear 10 meshes with the rack 12 and is driven by a servo motor, which is electrically connected to an external controller. Grooves are evenly spaced on the lower extension frame 11, and a trigger switch 15 is fixedly mounted inside each groove. The trigger switch 15 is electrically connected to the external controller. A spring 14 is fixedly mounted inside each groove, and a contact block 13 is slidably mounted inside each groove. The contact block 13 is fixedly connected to one end of the spring 14. By providing the drive triggering component, when using the industrial camera 8 to acquire images of paper and film, the drive gear 10 is controlled to trigger the triggering component. The rotation of the drive gear 10 and its meshing with the rack 12 can drive the industrial camera 8 to move at a constant speed above the paper and film rewinding area. At the same time, when the industrial camera 8 moves at a constant speed, the drive gear 10 meshes with the rack 12 and the toothed block on the drive gear 10 contacts the pressure block 13 and presses to trigger the corresponding trigger switch 15. When the trigger switch 15 is pressed, the industrial camera 8 acquires an image once. During the uniform speed lateral movement of the industrial camera 8, the image acquisition range of the industrial camera 8 is expanded by acquiring images multiple times at intervals to ensure that the paper and film rewinding area can be completely covered and detected. The acquired images are transmitted to the vision inspection system for processing, analysis and comparison to reflect whether the paper and film have indentations. The tension of the paper and film is adjusted according to whether indentations have appeared to prevent the paper and film from continuously developing indentations.

[0024] The working principle of this utility model is as follows: When rewinding paper and film, the paper and film pass through the underside of the tension roller 3 and extend to the side of the rewinding roller 2. One end of the paper and film is fixed on the rewinding roller 2. During rewinding, the rewinding roller 2 is controlled to rotate to rewind the paper and film.

[0025] During paper and film rewinding, the drive gear 10 is controlled to rotate. When the drive gear 10 rotates, it meshes with the rack 12 and drives the mounting base 7 and the industrial camera 8 to move horizontally at a constant speed. When the moving base 6 moves horizontally at a constant speed, the drive gear 10 continues to rotate. When the drive gear 10 rotates to the point where its tooth block contacts the pressing block 13 on the rack 12 and presses down on the pressing block 13, the pressing block 13 moves downward under the pressure of the tooth block and contacts the trigger switch 15 to press the trigger switch 15. When the trigger switch 15 is triggered, the industrial camera 8 starts and performs an image acquisition. By pressing the trigger switch 15 at intervals during the horizontal movement of the industrial camera 8, multiple image acquisition operations on the paper and film can be achieved by the industrial camera 8 at intervals. After the industrial camera 8 acquires images of the paper and film, the acquired images are transmitted to the vision inspection system. The vision inspection system performs preprocessing and feature extraction on the acquired images. Based on the extracted features, it compares them with the standard images when the paper and film do not have indentations and outputs the analysis results to reflect whether indentations have occurred during paper and film rewinding.

[0026] If indentations are detected on the paper or film, the electric cylinder is controlled to drive the tension roller 3 to rise and fall. When the tension of the paper or film is too high and indentations occur, the tension roller 3 is controlled to fall to reduce the tension of the paper or film.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
