[0049] Specifically, Figure 5 Show Figure 4 A magnified view of a section marked A in the middle; Figure 6 This diagram shows a structural schematic of the correction drive mechanism provided in an embodiment of the present invention. Figure 7 This is a top view of the correction drive mechanism provided in an embodiment of the present invention. (Refer to...) Figures 3-7 The correction drive mechanism 200 includes a supporting rotating shaft 210, a drive assembly, and a bracket connector 220. The axis of the supporting rotating shaft 210 is arranged along the first axial direction and is rotatably connected to the bottom plate 123 of the bracket structure 120, and is angularly arranged with respect to the length direction of the correction roller 110. In this embodiment, the angle between the supporting rotating shaft 210 and the length direction of the correction roller 110 is a right angle. The bracket connector 220 is rotatably connected to the bottom plate 123 and connected to the output end of the drive assembly. The drive assembly can drive the bracket connector 220 along the first direction, and the bracket structure 120 can swing around the supporting rotating shaft 210 under the drive of the bracket connector 220.

[0050] More specifically, the bracket connector 220 includes an L-shaped seat and a support shaft rotatably inserted in the L-shaped seat. The support shaft is rotatably connected to the base plate 123 about its own axis and can serve as a connecting component between the drive assembly and the base plate 123 to transmit the action of the drive assembly to the base plate 123, causing the base plate 123 to swing.

[0051] More specifically, the correction device also includes a base 500, on which the supporting rotation shaft 210 and the drive assembly are both disposed, in order to improve the structural integration of the correction device.

[0052] Continue to refer to Figure 4 , Figure 6 and Figure 7 The drive assembly includes a drive member 230, a lead screw 240, a sliding assembly 250, and a sliding limit assembly 260. The sliding limit assembly 260 is fixed relative to the drive member 230.

The sliding assembly 250 is slidably connected to the sliding limit assembly 260 in the first direction, and the bracket connector 220 is connected to the sliding assembly 250. In this embodiment, the drive member 230 can specifically be a motor or the like.

[0053] Specifically, the drive assembly further includes a drive mounting base 280, which is disposed on the base 500. The drive member 230 and the sliding limit assembly 260 are respectively fixedly disposed on the drive mounting base 280, and the sliding assembly 250 is slidably positioned on the drive mounting base 280 along a first direction.

[0054] More specifically, the sliding limiting assembly 260 includes a first positioning connection structure 261 and a sliding limiting rod 262. The first positioning connection structure 261 is fixedly disposed on the drive mounting base 280, and the sliding limiting rod 262 is disposed parallel to the lead screw 240 and fixedly connected to the first positioning connection structure 261. The sliding limiting rod 262 is slidably connected through a portion of the sliding assembly 250.

[0055] As a preferred option, refer to Figure 7 Specifically, there are two sliding limit rods 262, which are parallel to each other and spaced apart. They are respectively connected to the first positioning connection structure 261 and pass through a portion of the sliding assembly 250. This arrangement improves the reliability of the sliding limit rods 262 in guiding the sliding assembly 250. In this embodiment, the sliding limit rods 262 can be slidably connected to a portion of the sliding assembly 250 via linear bearings or the like.

[0056] More specifically, the sliding assembly 250 includes a slider 251 and a guide rod 252 connected to each other. A lead screw 240 is screwed through the slider 251 and rotatably connected to the first positioning connection structure 261 via bearings or the like. The first positioning connection structure 261 is located on the side of the slider 251 opposite to the drive member 230. The bracket connector 220 is connected to the end of the guide rod 252 away from the slider 251. The guide rod 252 is relatively movable through the first positioning connection structure 261 via linear bearings or the like. The guide rod 252 can move relative to the first positioning connection structure 261 under the rotational drive of the lead screw 240, thereby causing the bracket connector 220 to move in a first direction, causing the base plate 123 to swing about the support rotation axis 210.

[0057] Preferably, there are two guide rods 252. The two guide rods 252 are parallel to each other and spaced apart to ensure the straightness of the movement of the bracket connector 220 in the first direction.

[0058] Preferably, the sliding limiting assembly 260 further includes a second positioning connection structure 263. The second positioning connection structure 263 is located between the driving member 230 and the sliding assembly 250, disposed on the driving mounting base 280, and fixedly connected to the sliding limiting rod 262. The driving member 230, its output end, and the lead screw 240 are interconnected within the second positioning connection structure 263, and the lead screw 240 is rotatable relative to the second positioning connection structure 263.

[0059] Continue to refer to Figure 4 and Figure 5 The correction device also includes a guide mechanism 400. The guide mechanism 400 has a block-shaped structure, extends along the swing path of the support structure 120, and is angled to the first direction. A guide connector is provided below the base plate 123, connected to the guide mechanism 400, and is movable along the extending direction of the guide mechanism 400. Through the cooperation of the guide mechanism 400 and the guide connector, support and guidance can be provided to the base plate 123 when the support structure swings.

[0060] Specifically, the guide connector includes a roller 121 and a connecting seat 122. The connecting seat 122 is connected to the support structure 120, and the roller 121 is rotatably connected to the connecting seat 122. The guide mechanism 400 has a guide groove 410 along its extension direction, and the roller 121 is rotatably disposed in the guide groove 410. By providing the roller 121, the stability of the support connector 220 during swing can be improved, thereby ensuring the stability of the correction process of the correction roller 110.

[0061] More specifically, there are two guide mechanisms 400, symmetrically arranged on both sides of the correction drive mechanism 200, both mounted on the base 500, and the distance between the two guide mechanisms 400 gradually decreases along a direction perpendicular to the first direction and away from the support rotation axis 210. When the support structure 120 swings around the support rotation axis 210 under the action of the correction drive mechanism 200, the two rollers 121 can roll and move in the corresponding guide grooves 410 respectively, thereby providing guidance and support for the swing of the support structure 120.

[0062] Continue to refer to Figure 3 and Figure 6 The correction device also includes a sensing mechanism 300. The sensing mechanism 300 is fixedly disposed relative to the sliding limit assembly 260. The sensing mechanism 300 includes a first sensing element 310 and a second sensing element 320, which are mounted on a sensing mounting base 290. The sensing mounting base 290 is fixedly connected to the first positioning connection structure 261 and the second positioning connection structure 263. An actuating element 270 is disposed on the sliding assembly 250. The first sensing element 310 and the second sensing element 320 are respectively located on both sides of the actuating element 270 in a first direction. The actuating element 270 can approach the first sensing element 310 or the second sensing element 320 when the sliding assembly 250 moves along the first direction. The first sensing element 310 and the second sensing element 320 can respectively sense the actuating element 270. With the cooperation of the first sensor 310, the second sensor 320 and the actuating element 270, the correction device can automatically sense the swing direction of the correction roller 110.

[0063] Specifically, in this embodiment, the first sensor 310 has a sensing groove in which through-beams are formed. The actuating element 270 has an L-shaped sheet structure and can move with the slider 251 into the sensing groove to partially or completely block the through-beams. The control module can receive the signal from the first sensor 310 to determine the swing direction and offset distance of the corrected roller 110, so as to control the drive element 230 to restore the corrected roller 110. In this embodiment, the structure and sensing principle of the second sensor 320 are the same as those of the first sensor 310, and will not be described in detail here.
