[0002] A coated paper unwinding machine is an automated device used for coating and laminating paper substrates. Its main function is to laminate plastic film with flexible substrates such as paper and to achieve continuous unwinding. For example, the authorized patent with publication number CN221543451U (Roll material correction device for unwinding equipment) includes a non-woven fabric master roll support frame, a correction sensor and a sensor mounting frame; The aforementioned existing technology uses real-time monitoring results from a web-correcting sensor to control the reciprocating movement of the nonwoven fabric master roll support frame, solving the problem that the edge of the roll material remains in the same position after unwinding. However, relying solely on a web-correcting sensor to monitor the offset may result in insufficient web-correcting accuracy, failing to effectively guarantee the unwinding effect. Furthermore, controlling the entire nonwoven fabric master roll support frame to reciprocate increases the burden on the drive device, increases its size, and affects the accuracy of position adjustment. Therefore, the market urgently needs to develop an automatic web-correcting coated paper unwinding device to help solve the existing problems. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic correction and unwinding device for coated paper, which solves the problems mentioned in the background art, such as relying solely on correction sensors to monitor deviations, which may result in insufficient correction accuracy and inability to effectively guarantee the unwinding effect, while controlling the entire nonwoven fabric master roll support to reciprocate increases the burden on the drive device, increases its size, and affects the accuracy of position adjustment.

The top of the photoelectric sensor is fixedly connected to the automatic correction mechanism by an adjusting bolt, and the screw portion of the adjusting bolt is slidably connected to the automatic correction mechanism through an adjusting groove.

[0006] In a further embodiment, the automatic correction mechanism is provided with a fixed frame on the outside, and a first cylinder is provided on the outside of the fixed frame. The piston rod inside the first cylinder is fixedly connected to the automatic correction roller by bolts, and the inner end of the automatic correction roller is connected to the automatic correction mechanism by a fixed sliding sleeve.

[0007] In a further embodiment, anti-deviation baffles are provided at both ends of the outer surface of the pressure edge positioning roller, and the anti-deviation baffles are threadedly connected to the pressure edge positioning roller.

[0008] In a further embodiment, the film smoothing frame includes a lower smoothing roller and an upper smoothing roller, one end of which is embedded and connected to a fixed guard plate, and the middle position of the film smoothing frame is connected to the fixed guard plate by an angle adjustment bolt.

[0009] In a further embodiment, one end of the tension adjusting roller is connected to the fixed guard plate via a fixed slider and a fixed groove, and the fixed slider is fixedly connected to the second cylinder via bolts.

The tension adjusting roller 8 and the lower guide roller 9 are connected in a triangular structure. The position of the first unwinding shaft 3 and the second unwinding shaft 17 are rotated and interchanged by the rotating adjustment plate 2. The first unwinding shaft 3 and the second unwinding shaft 17 are used to place the reel. The fixed guard plate 13 is used to assemble and fix the unwinding mechanism. The automatic correction mechanism 6 is used to achieve automatic correction of the film paper. The film smoothing frame 5 is used to smooth the reel to prevent the film paper from loosening and affecting the flatness of unwinding. The edge positioning roller 12 and the limiting roller 11 are used to position the film paper unwinding position. The upper guide roller 7 is used to guide the direction of film paper unwinding. The tension adjusting roller 8 is used to adjust the tension of film paper unwinding.

The top of the photoelectric sensor 19 is fixedly connected to the automatic correction mechanism 6 by an adjusting bolt 23, and the screw part of the adjusting bolt 23 is slidably connected to the automatic correction mechanism 6 by an adjusting groove 24. The adjusting bolt 23 is used to adjust the position of the photoelectric sensor 19, and the photoelectric sensor 19 is used to monitor the position of the film paper feeding line in real time.

[0016] Furthermore, the automatic correction mechanism 6 is provided with a fixed frame 21 on the outside, and a first cylinder 20 is provided on the outside of the fixed frame 21. The piston rod 28 inside the first cylinder 20 is fixedly connected to the automatic correction roller 18 by bolts, and the inner end of the automatic correction roller 18 is connected to the automatic correction mechanism 6 through a fixed sliding sleeve 27.
