[0039] Please see Figure 1-5 As shown, this utility model embodiment provides a dual correction mechanism for a bag making machine, including a base 1, a sliding component 2, a manual correction component 4, and a CCD imaging gimbal automatic correction component 5.

[0040] Please see Figure 1 As shown, four sliding components 2 are respectively located at the four top corners of the base 1, and the main unwinding storage rack 3 is mounted on the four sliding components 2. The main unwinding storage rack 3 can move laterally on the four sliding components 2. Please refer to [link / reference]. Figure 4 As shown, in this embodiment, the sliding assembly 2 includes a linear slide rail 21 and a positioning block 22. The linear slide rail 21 is horizontally fixed to one corner of the top of the base 1 by bolts, and the linear slide rail 21 can be replaced individually. The positioning block 22 is fixedly installed on the slider of the linear slide rail 21 by screws. The top of the positioning block 22 has a positioning groove that matches the slider of the linear slide rail 21, ensuring that the positioning block 22 is firmly installed on the slider of the linear slide rail 21. A vertical side plate 23 that fits against the main unwinding storage rack 3 is provided on one side of the top of the positioning block 22. The vertical side plate 23 is fixedly connected to one corner of the bottom of the main unwinding storage rack 3 by screws. The four corners of the bottom of the main unwinding storage rack 3 are respectively fixedly installed on the corresponding four positioning blocks 22, ensuring that the main unwinding storage rack 3 can move horizontally and stably along the four linear slide rails 21.

[0041] Please see Figure 3 As shown, the manual alignment component 4 is located between the base 1 and the main unwinding storage rack 3. The manual alignment component 4 is used to drive the main unwinding storage rack 3 to move laterally. Please refer to [link / reference]. Figure 4As shown, in this embodiment, the manual alignment component 4 includes a support rod 41, a ball screw 42, and a handwheel 43. The bottom end of the support rod 41 is fixedly installed on a corner of the base 1 near the rear unwinding rack 6 by screws. The ball screw 42 is parallel to the linear guide rail 21. The threaded sleeve of the ball screw 42 is fixedly embedded in the main unwinding storage rack 3, and one end of the ball screw 42 is rotatably inserted into the top end of the support rod 41 through a bearing. The handwheel 43 is fixedly connected to the end of the ball screw 42 inserted into the support rod 41, and a handle 44 is provided on the handwheel 43. When the operator rotates the handwheel 43 through the handle 44, the ball screw 42 drives the main unwinding storage rack 3 to move laterally along the linear guide rail, realizing the coarse alignment of the main unwinding storage rack 3. The alignment range of the manual alignment component 4 is ±100mm, and the adjustment accuracy is ±1mm. Preferably, the surface of the ball screw 42 is coated with a titanium nitride coating to reduce wear. The handwheel 43 is equipped with a dial, with each division corresponding to a 1mm displacement, which facilitates precise adjustment by the operator.

[0042] Please see Figure 1 As shown, the CCD imaging gimbal automatic correction component 5 is mounted on the rear insert feeding rack 6. The CCD imaging gimbal automatic correction component 5 captures real-time images of the pattern between the edge of the film and the detection roller 61. Please refer to... Figure 2 As shown, the CCD imaging gimbal automatic correction assembly 5 includes a CCD camera 51, an image processor, and an electric correction component. The CCD camera 51 is located on one side of the detection roller 61 above the rear insertion and feeding rack 6. The image processor and the CCD camera 51 are integrated into a single structure, and the image processor is communicatively connected to both the CCD camera 51 and the electric correction component.

[0043] Please see Figure 5 As shown, in this embodiment, the electric correction component includes two linear tracks 52, an outward-facing angle adjustment plate 53, and an electric cylinder 54. The two linear tracks 52 are arranged parallel to each other within the rear insert feeding rack 6. The outward-facing angle adjustment plate 53 is slidably connected between the two linear tracks 52, and its top is rotatably connected to the gimbal. There are two outward-facing angle adjustment plates 53, symmetrically arranged on the linear tracks 52. The electric cylinder 54 is fixedly arranged between the two linear tracks 52, and its output end is rotatably connected to the outward-facing angle adjustment plate 53. The extension and retraction of the output end of the electric cylinder 54 pushes the outward-facing angle adjustment plate 53 to move along the linear tracks. The outward-facing angle adjustment plate 53 causes the gimbal to deflect, which in turn causes the roller above the gimbal to deflect, ensuring accurate material feeding without edge misalignment.

[0044] During operation, the CCD camera 51 captures real-time images of the pattern between the edge of the film and the detection roller 61 above the rear insertion rack 6. Preferably, the CCD camera 51 is equipped with an adaptive LED light source, which automatically adjusts the brightness of the supplementary light according to the ambient light intensity to ensure image clarity. The image processor performs edge detection on the image captured by the CCD camera 51, calculates the deviation value, and sends a command to the electric cylinder 54 of the electric correction component. The electric cylinder 54 deflects the gimbal according to the command, and the gimbal drives the roller on the gimbal to deflect by an angle, thereby causing the film to be finely adjusted laterally to ensure accurate film feeding without edge misalignment. The correction angle range is ±7°, and the correction accuracy is 0.1mm.

[0045] This invention achieves high-precision alignment of the material film by combining manual alignment with automatic alignment via a CCD imaging gimbal. The manual alignment component 4 uses a ball screw 42 and a linear guide for coarse adjustment, while the CCD automatic alignment uses image recognition and an electric cylinder 54 for fine adjustment. This invention effectively reduces the frequency of manual intervention, improves production efficiency and product consistency, and is suitable for high-speed bag-making machines.

[0046] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
