[0034] Unwinding Process: The artificial leather roll is mounted on the unwinding shaft of the unwinding device. The unwinding motor drives the unwinding shaft to rotate, starting the unwinding process. The unwinding tension adjusting roller on the unwinding tension adjusting frame adjusts the tension of the artificial leather to ensure stable tension during unwinding, allowing the artificial leather to be smoothly conveyed to the front storage device. Front Storage Adjustment: When the storage length of the front storage device needs to be adjusted, the lifting pressure cylinder extends or retracts, driving the lifting roller frame to rise or fall via the traction rope and pulley system. This changes the distance between the upper and lower roller groups, adjusting the storage length to accommodate speed changes in subsequent processes. Visual Inspection: The artificial leather is conveyed to the visual inspection device via the leather conveyor. The light source component provides uniform illumination. Under the protection of the light shield component, the visual inspection component takes pictures at a set frequency and position to acquire image information of the artificial leather surface. The image data is transmitted to the main controller in the electrical cabinet component. The main controller processes and analyzes the images, determines the presence of defects, and displays the inspection results on the monitor in real time. Winding and Post-Storage: The visually inspected artificial leather is initially wound up by the upper winding roller and lower guide roller assembly of the winding device, and then conveyed to the post-storage device. The post-storage device operates on the same principle as the front storage device, adjusting the storage length via the roller frame lifting and adjusting mechanism to ensure stable tension of the artificial leather conveyed to the winding device. Winding Process: The winding device employs a dual-station winding method. After the artificial leather on the front winding shaft is wound up, the front winding motor stops, the rear winding motor starts, and the rear winding shaft begins winding. Simultaneously, the empty roll on the front winding shaft is replaced, achieving roll change without stopping the machine and improving winding efficiency. The winding tension adjusting roller on the winding tension adjusting frame adjusts the winding tension to ensure winding quality.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
