Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Referring to fig. 1 and fig. 2, an on-line pre-tightening deviation-rectifying device 2 of a continuous web-forming apparatus in a preferred embodiment of the present invention is used for rectifying deviation and pre-tightening a mesh belt 3 of the continuous web-forming apparatus 100 to improve the yield and production efficiency of the melt-blown non-woven fabric. Wherein, continuous web-forming equipment 100 includes support 1, and correspondingly, online pretension deviation correcting device 2 includes: the device comprises a plurality of conveying guide rollers 21 which are mutually parallel and rotatably installed on a support 1, a deviation rectifying roller 22 which is rotatably arranged on the support 1, and a driving mechanism 23 which is in transmission connection with the deviation rectifying roller 22 and is used for driving the deviation rectifying roller 22 to move, wherein the axial lines of the plurality of conveying guide rollers 21 are vertical to the conveying direction of the mesh belt 3, so that a conveying base plane is formed, and the mesh belt 3 can stably run on the conveying base plane.
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 synchronous motion is as follows: the two adjusting cylinders 231 drive the deviation rectifying rollers 22 to move for the same distance; the asynchronous movement is: according to the deviation condition of the mesh belt 3, only one of the adjusting cylinders 231 is controlled to drive one end of the deviation rectifying roller 22 to move, or two adjusting cylinders 231 are controlled to respectively drive two ends of the deviation rectifying roller 22 to move different distances. 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.
Correspondingly, a pair of slide rails 11 are arranged on the support 1, a pair of slide rails 11 are respectively connected with a bearing with seat 24 in the slide rails 11 in a sliding manner, the adjusting cylinder 231 comprises a cylinder body rotatably connected to the support 1 and a piston rod rotatably connected with the bearing with seat 24, and the bearing with seat 24 is connected with the piston rod and can also enable the rectification roller 22 to rotate in the bearing with seat 24. The end of the cylinder body away from the pedestal bearing 24 is fixed in the slide rail 11, and the fixing mode can be realized by a fastener, a clamping, a welding and the like, which is not described herein.

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.

In this embodiment, the deviation correcting sensor 25 is an infrared sensor or a laser sensor, which has high sensitivity and can monitor whether the mesh belt 3 is deviated in time. Indeed, in other embodiments, the deviation sensor 25 may be other, and is not limited herein, according to the actual situation.
The control mechanism is an air pressure adjusting mechanism for adjusting the air pressure transmitted to the adjusting cylinder 231, thereby adjusting the tension applied to the mesh belt 3 by the adjusting cylinder 231. Wherein, the pretightening force is specifically that the control mechanism is applied to the driving mechanism 23, and is transmitted to the deviation rectifying roller 22 through the driving mechanism 23 and then is applied to the mesh belt 3; meanwhile, the control mechanism can also control the tension force applied to the mesh belt 3 by the driving mechanism 23 according to actual production requirements, and then the yield of the mesh belt 3 is improved. The air pressure adjusting mechanism can be an air pump, an adjusting valve connected with the air pump, and the like, and is not particularly limited herein, and is determined according to actual conditions.

In the second working state, the mesh belt is deviated to the left side or the right side in the conveying process, in this embodiment, for example, the mesh belt is deviated to the right side, the right deviation-rectifying sensor 25 is triggered by the mesh belt, the right deviation-rectifying sensor 25 immediately sends an alarm signal to the control mechanism, the control mechanism adjusts one or two adjusting cylinders 231 to lift the left end of the deviation-rectifying roller 22, at this time, the axis of the deviation-rectifying roller 22 is intersected with the conveying base surface, and the left end of the deviation-rectifying roller 22 is lifted by a first distance relative to the right end, the first distance is usually controlled within 10-50 mm, so that the mesh belt is reversely distorted and deformed to restore the flatness of the mesh surface. 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.
