The deviation rectifying roller 22 is provided between any two adjacent conveying guide rollers 21, and is configured to provide a pre-tightening force to the mesh belt 3, so that the mesh belt 3 is tensioned between the deviation rectifying roller 22 and the plurality of conveying guide rollers 21. The purpose of setting the pretightening force is as follows: the mesh surface of the mesh belt 3 is prevented from being too loose or too tight during conveyance, which in turn causes flaws in the mesh belt 3. The magnitude of the pre-tightening force is determined according to actual conditions, and is not particularly limited herein. In the present embodiment, the rectification roller 22 is disposed between any two adjacent conveying rails along the axial direction of the continuous web forming apparatus 100, and indeed, in other embodiments, the disposition position of the rectification roller 22 may be other, and is not particularly limited herein, depending on the actual situation.
In the present embodiment, the driving mechanism 23 includes two adjusting cylinders 231, and the two adjusting cylinders 231 are respectively abutted with the end portions of the rectification rollers 22. And, the movements of the two adjusting cylinders 231 are synchronized or not synchronized.

The purpose of this is to: when the adjusting cylinder 231 moves synchronously, a tension force can be applied to the mesh belt 3 to ensure the quality of the mesh belt 3 in the forming process; when rectifying arbitrary tip of roller 22 and taking place the skew, can make two actuating cylinder 231's motion asynchronous, thereby drive arbitrary actuating cylinder 231 promptly and adjust in order to carry out reverse distortion to guipure 3 to the tip of skew, and then rectify a deviation, convenient and fast to guipure 3. Indeed, in other embodiments, the number of the adjusting cylinders 231 may be other, and is not limited herein, according to the actual situation.

If the slide rail 11 is vertically provided on the bracket 1, correspondingly, the adjusting cylinder 231 is also vertically provided on the bracket 1. When the adjusting cylinder 231 drives the rectification roller 22 to move upwards, the rectification roller 22 drives the mesh belt 3 to move upwards, so that the tension force applied to the mesh belt 3 is increased, and then the mesh belt 3 is damaged or even tensed and broken.
The online pre-tightening deviation correcting device 2 further comprises at least one pair of deviation correcting sensors 25 and a control mechanism in signal connection with the deviation correcting sensors 25 and the driving mechanism 23, wherein the at least one pair of deviation correcting sensors 25 are respectively arranged on two sides of the mesh belt 3 and are arranged to be triggered when the mesh belt 3 deviates.

When the net belt is normal in shape, the control mechanism rapidly enables the two adjusting cylinders 231 to restore balance so as to apply pretightening force to the net belt.
In summary, the following steps: through the arrangement of the deviation rectifying sensor 25, the deviation rectifying roller 22 and the driving mechanism 23 for driving the deviation rectifying roller 22, the driving mechanism 23 applies a pretightening force to the deviation rectifying roller 22 so as to apply the pretightening force to the mesh belt 3 by the deviation rectifying roller 22, thereby preventing the mesh surface of the mesh belt 3 from being too loose or too tight; simultaneously the sensor 25 of rectifying is used for monitoring whether guipure 3 squints, and when the sensor 25 of rectifying monitors guipure 3 squints, actuating mechanism 23 can drive the tip of rectifying roller 22 and keeping away from sensor 25 one side of rectifying and raise, then carries out reverse distortion to guipure 3 to make guipure 3 level and smooth, improve the yield of melt-blown non-woven fabrics, improve production efficiency then, convenient and fast.
