Description

Technical Field

[0001] The present invention relates to the technical field of follow-up unwinding of diversion cloth, and specifically relates to a follow-up tracking unwinding device for diversion cloth. Background Technique

[0002] The diversion cloth mainly plays the roles of conduction, diffusion, rapid infiltration, and preventing reverse infiltration. It can enable the liquid to quickly and evenly transfer along the length direction to the water-absorbing core layer after reaching this layer, maximizing the absorption efficiency of SAP (superabsorbent resin) in the core layer, effectively preventing the occurrence of liquid leakage in sanitary products (such as diapers, sanitary napkins, etc.). When producing the diversion cloth, an unwinding device is needed for unwinding. The follow-up tracking unwinding device is a device that can be used to automatically adjust the unwinding position of the diversion cloth.

[0003] When the follow-up tracking unwinding device unwinds the diversion cloth, it can automatically adjust the position of the unwinding mechanism according to the monitoring results to ensure that the diversion cloth always maintains the correct position during the unwinding process. In the prior art, when following up and tracking the tension of the diversion cloth, most of them use a single pressure roller for adjustment, and the pressure distribution may be uneven. Due to the limited contact area between the pressure roller and the diversion cloth, there may be situations where the local pressure is too large or too small. This will cause the diversion cloth to be subjected to uneven tension during the conveying process, thereby affecting its flatness and stability, and affecting the subsequent processing or use effect. Secondly, when the follow-up tracking unwinding device is working, due to the friction between the roller and the diversion cloth, dust in the air will adsorb on the diversion cloth. With the increase of dust, the friction coefficient between components will increase, changing the original mechanical properties, which will affect the tension stability of the diversion cloth, thereby affecting the subsequent processing or use effect. Therefore, we propose a follow-up tracking unwinding device for diversion cloth. Summary of the Invention

[0040] By adopting the above technical solution, the swing of the second deflector 811 can change the wind direction, so that the dust on the surface of the guide cloth can be blown away better.

[0041] Working principle: The unwinding device 5 unwinds the guide cloth. The winding device 6 can convey the guide cloth. The guide cloth is located below the three groups of pressure rollers 302. When the tension sensor 7 detects that the guide cloth is loose during transportation (the tension sensor 7 is an instrument used to measure the tension value of the guide cloth in the tension control process. Generally, we can choose to install the tension sensor near the guide cloth to ensure that the sensor can accurately measure the tension of the guide cloth. When in use, the tension sensor 7 is connected to the control CPU. The tension sensor 7 sends a signal to the CPU. The CPU processes the signal and conveys the instruction to the corresponding actuator. This actuator is the tension adjustment mechanism 3. This is the prior art), the electric telescopic rod 300 drives the support plate 301, the first connection frame 303 and the second connection frame 305 to move downward, so that the pressure roller 302 can squeeze the guide cloth, thereby tensioning the guide cloth; When adjusting the distance between the pressure rollers 302 as needed, the motor 406 drives the disc 407 to rotate. The disc 407 drives the second connecting rod 408 to perform a circular motion. The second connecting rod 408 drives the first connecting rod 404 to rotate. The first connecting rod 404 drives the guide block 403 to move. The guide block 403 drives the guide rod 401 to move within the guide groove 411. The guide rod 401 can squeeze the lifting plate 409, and the lifting plate 409 moves downward. Under the action of the moving groove 410, the moving rod 307 is squeezed. The moving rod 307 drives the rotating tube 304 to move. The rotating tube 304 drives the pressure rollers 302 to move, enabling the distance to be adjusted according to the thickness of different flow guiding fabrics, avoiding uneven pressure distribution caused by excessive gaps, and improving the tension stability of the flow guiding fabric. The fan 200 transports the filtered air to the rotating tube 304 through the first delivery pipe 201 and the second delivery pipe 203. Under the action of the air holes 208, the air enters the air cavity 206. Then, under the action of the first deflector 210, the air is quickly introduced into the intake through groove 207. Then the air enters the cavity 209, and the wind speed drives the blades 802 to rotate. The blades 802 can indirectly squeeze the pressing plate 803 and the pressing rod 805, so that the spring 804 is squeezed. The pressing rod 805 drives the connecting frame 807 to move. The connecting frame 807 drives the connecting column 812 to move within the slotted groove 813. The connecting column 812 can drive the connecting disc 808 to rotate. The connecting disc 808 drives the rotating rod 809 to rotate. The rotating rod 809 drives the second deflector 811 to rotate. Under the elastic force of the spring 801, the pressing rod 805 can reciprocate, so that the disc 808 can rotate reciprocally, and thus the second deflector 811 can swing, realizing the dynamic adjustment of the air outlet direction, being able to blow the surface of the flow guiding fabric more comprehensively, and improving the dust removal effect.
