Technical Field

[0001] The utility model relates to the technical field of airflow film production, in particular to an airflow film deviation correction and winding device. Background Art

[0002] Airflow film is a material used in the industrial and packaging fields with many important properties and applications. It is made by a special manufacturing process that processes polymers and other materials into a thin film, and realizes different functions through airflow. Airflow film is usually made of plastic materials such as polyethylene and polypropylene, and has the characteristics of being light and thin. The airflow film correction and winding device is a device used in the industrial field, mainly used for correcting and winding the rolls during the production process. It adjusts the position of the roll by controlling the airflow to ensure the flatness and accuracy of the roll during the winding process.

[0003] After searching, the publication number CN220787565U was found. The specific name is a film deviation correction and rewinding device, which includes a frame, a guide roller and a rewinding shaft rotatably provided in the frame, a support platform fixedly provided on the frame, a slide rail assembly provided on the support platform, a film frame provided at the movable end of the slide rail assembly, a rotating shaft for placing a protective film roll rotatably provided in the film frame, a drive assembly provided on the support platform, and the drive assembly driving the mold frame to move along the axis direction of the guide roller;

[0004] When installing a traditional deviation-correcting and winding device, an independent device is usually set up between the guide roller and the winding roller. Due to the large overall structure of the deviation-correcting device, the entire device is driven and moved by a mobile device during the deviation-correcting process. The overall movement requires a large power support, resulting in increased energy consumption of the equipment. Due to its large size, installation complexity, inconvenient adjustment, energy consumption and maintenance issues, production efficiency will be reduced and operating costs will increase.

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: an airflow film deviation correction and winding device, comprising a winding device body 101 and a guide roller 1 and a winding roller 3 rotatably connected to the winding device body 101, the guide roller 1 and the winding roller 3 are both driven to rotate by a stepping motor, and a rotating component 2 and a sensor 102 are installed on the winding device body 101;

[0024] The rotating assembly 2 includes a positioning bearing 21 fixedly mounted inside the winding device body 101, the inner ring of the positioning bearing 21 is fixedly connected to the roller 22, both ends of the roller 22 extend to the interior of the winding device body 101, the outer surface of the roller 22 is sleeved with a roller 23, the end face of the roller 22 is fixedly mounted with a servo motor 24, the outer surface of the servo motor 24 is fixedly mounted inside the winding device body 101, the outer surface of the roller 22 is fixedly sleeved with a positioning rod 221, the positioning rod 221 is hexagonal, the interior of the roller 23 is provided with a hexagonal limiting groove matching the positioning rod 221, the outer surface of the positioning rod 221 is slidably connected to the interior of the hexagonal limiting groove, the inner wall of the roller 23 is provided with a rotating groove 231, and a correction assembly 4 is installed inside the roller 22, the correction assembly 4 includes a fixed bearing 41 fixedly mounted on the inner wall of the roller 22, the inner ring of the fixed bearing 41 is fixedly connected to an electric telescopic rod 42, and the electric telescopic rod 42 is connected to the sensor 102 signal. The output end of the electric telescopic rod 42 is fixedly connected to a connecting rod 43, and a positioning plate 44 is fixedly connected to the surface of the connecting rod 43. The rotating groove 231 is annular, and the surface of the positioning plate 44 extends to the outside of the roller shaft 22 and is inserted into the inside of the rotating groove 231. The end of the electric telescopic rod 42 away from the connecting rod 43 is fixedly connected to a fixing rod 46, and the end of the fixing rod 46 away from the electric telescopic rod 42 is fixedly connected to a fixing plate 47. By setting the rotating component 2 and the correcting component 4, when the sensor 102 detects the tilt of the airflow film, the electric telescopic rod 42 can be controlled to start, and the steel ball 45 can be driven to move through the connecting rod 43. The positioning plate 44 can be pressed against the inner wall of the rotating groove 231 to make the roller 23 slide outside the roller shaft 22, thereby realizing the position correction of the airflow film, thereby ensuring the winding quality. By relative adjustment of the position between the roller shaft 22 and the roller 23, the correction effect can be quickly achieved, the mechanical structure can be simplified, the number of components can be reduced, and the failure rate can be reduced.

[0025] Steel balls 45 are movably installed equidistantly inside the positioning plate 44. The surface of the steel balls 45 extends to the outside of the positioning plate 44 and abuts against the inner wall of the rotating groove 231. The fixed plate 47 is fixedly connected to the inside of the winding device body 101 by bolts. By providing the steel balls 45, when the roller 23 rotates, the friction between the positioning plate 44 and the inner wall of the rotating groove 231 can be reduced, thereby extending the service life of the connecting parts. In addition, by providing the fixed plate 47, when the entire deviation correction device has an abnormality, the entire rotating assembly 2 can be quickly disassembled and replaced.

[0026] The detection by the sensor 102 and the activation of the electric telescopic rod 42 by the controller generally involve the following key steps and processes:

[0027] First, the sensor 102 is used to monitor the state of the airflow membrane in real time, mainly to detect whether the airflow membrane is offset. The sensor may use a photoelectric sensor, a contact sensor or other types of sensors, which can accurately identify the degree of inclination or deviation of the airflow membrane. When the sensor detects an offset, it converts the data into an electrical signal, indicating that the airflow membrane is in an abnormal state. The sensor inputs the collected signal to the controller through a cable or wireless transmission. This signal is usually a digital or analog signal, which varies depending on the type of sensor. After the controller receives the signal from the sensor 102, it processes and analyzes it, and the built-in program of the controller will judge the airflow based on the received signal. Whether the membrane is indeed offset, if the offset exceeds the set threshold, the electric telescopic rod 42 will be started. Once the controller confirms that adjustment is needed, it will send a start command to the electric telescopic rod 42. After receiving the control command, the electric telescopic rod 42 will start its motor to drive the telescopic rod to perform telescopic movement. When the electric telescopic rod is active, it pushes the positioning plate 44 to move through the connecting rod. During the movement, the positioning plate 44 will abut against the outer surface of the roller 23, thereby adjusting the roller 23 relative to the roller shaft 22 so that its position gradually returns to the correct position. After the correction is completed, the system can detect the status of the airflow membrane again through the sensor to ensure that the correction has been successful and the position has returned to normal.

[0028] When working, the air flow film is wound by the rotation of the winding roller 3. During the winding process of the air flow film, if there is any deviation, it is detected by the sensor 102, and the controller controls the electric telescopic rod 42 to start. After the electric telescopic rod 42 is started, the positioning plate 44 is driven to move through the connecting rod 43, and the positioning plate 44 is abutted against the roller 23, so that the roller 23 can slide outside the roller shaft 22, thereby correcting the position of the air flow film on the outer surface of the roller 23, thereby ensuring the winding quality. By relative adjustment of the position between the roller shaft 22 and the roller 23, the correction effect can be quickly achieved, the mechanical structure can be simplified, the number of components can be reduced, and the failure rate can be reduced. When the roller 23 rotates, the friction between the positioning plate 44 and the inner wall of the rotating groove 231 can be reduced by the rolling of the steel ball 45 on the inner wall of the rotating groove 231, thereby extending the service life of the connecting part. In addition, by setting the fixed plate 47, when the deviation correction device as a whole has an abnormality, the rotating component 2 can be quickly disassembled and replaced as a whole.
