[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. By integrating a dust-free chassis, an image recognition module, and an intelligent control module, the present invention uses a camera to capture the image information of the packaging bags in real time, and accurately identifies the shape, size, position, and surface defect data of the packaging bags in the image through an image processing module, a feature extraction unit, and a pattern matching unit, ensuring that the product quality meets the preset standards, improving the accuracy of image recognition, and guaranteeing the accuracy and reliability of product quality control;

[0028] 2.

A second servo motor is arranged on the support plate at the bottom of one side of the first moving block, and the driving roller connected to its output end directly acts on the outer wall of the packaging bag roll material. Through the drive of the second servo motor, the precise output of the packaging bag is realized, which not only helps to improve the automation degree of the bag winding machine, but also ensures the uniformity of the packaging bag conveying and production efficiency through precise servo motor control;

[0030] 4. When the present invention performs the winding operation, first, the fifth servo motor is started. This motor drives the first telescopic cylinder and the second telescopic cylinder to operate in coordination. The main responsibility of the first telescopic cylinder is to accurately adjust the position of the second telescopic cylinder and the limiting plate connected thereto according to the actual width of the packaging bag, so as to ensure the accuracy and stability of the winding process. The second telescopic cylinder is responsible for the actual winding of the packaging bag. When the winding process is successfully completed, the fourth servo motor is immediately started to drive the rotating disk to rotate smoothly. At the same time, the second telescopic cylinder performs a contraction action. This series of actions ensures that the wound packaging bag can smoothly enter the storage box under the guidance of the guiding plate without error. At the same time, during the continuous rotation of the rotating disk, another group of the fifth servo motor and the second telescopic cylinder can seamlessly connect to perform the next round of winding operation on the cut packaging bag, thereby not only improving the work efficiency, but also ensuring the coherence and automation level of the entire winding process.

The setting of the bearing 32 ensures the smooth rotation of the tensioning roller 33. At the same time, the cutting table 34 in the middle of the dust-free chassis 1 is equipped with a fixed plate 36 and a tool holder 37 on the support column 35, and the cutting knife 38 provided at the output end of the tool holder 37 can effectively perform material cutting operations, which can improve the accuracy and efficiency of material processing and ensure the stability and reliability of the operation process. By fitting a fourth servo motor 41 in the setting groove 40, the rotating disk 42 connected to the output end thereof is not only provided with a plurality of guide rods 43 on one side for guiding the movement of the packaging bag but also provided with a fifth servo motor 44 at both ends on the other side.

One end of the first telescopic cylinder 46 is also connected to the second telescopic cylinder 47, and the output end of the second telescopic cylinder 47 penetrates through the limit plate 48. Such a double telescopic design is beneficial to enhancing the flexibility and accuracy of the packaging bag during the winding and collection processes. In addition, the storage box 49 provided on one side of the inner bottom wall of the dust-free chassis 1 and the guiding plate 50 on the top provide a convenient collection path for the wound packaging bag. The second box door 51 provided on the back through a hinge facilitates the maintenance and repair of the inside of the dust-free chassis 1, thereby ensuring the high efficiency and stability of the packaging bag production. When performing the winding operation, first start the fifth servo motor 44, which drives the first telescopic cylinder 46 and the second telescopic cylinder 47 to operate in coordination. The main responsibility of the first telescopic cylinder 46 is to accurately adjust the position of the second telescopic cylinder 47 and the limit plate 48 connected thereto according to the actual width of the packaging bag to ensure the accuracy and stability of the winding process. The second telescopic cylinder 47 is responsible for the actual winding of the packaging bag. When the winding process is successfully completed, the fourth servo motor 41 is immediately started to drive the rotating disk 42 to rotate smoothly. At the same time, the second telescopic cylinder 47 performs a contraction action. This series of actions ensures that the wound packaging bag can smoothly enter the storage box 49 under the guidance of the guiding plate 50 without error. At the same time, during the continuous rotation of the rotating disk 42, another group of the fifth servo motor 44 and the second telescopic cylinder 47 can seamlessly connect to perform the next round of winding operation on the cut packaging bag, thereby not only improving the work efficiency but also ensuring the coherence and automation level of the entire winding process.
