DETAILED DESCRIPTION

[0015] Example 1: See Figure 1-7A deflection correction and adjustment device for unwinding is arranged between a left wall panel 01 and a right wall panel 02, and a printing medium 00 flows from back to front between the two wall panels; the deflection correction and adjustment device for unwinding comprises a deflection correction roller 1 and a lifting mechanism; the left end of the deflection correction roller 1 is vertically hinged with the left wall panel, and the right end passes through the right wall panel; the lifting mechanism is arranged on the outer side of the wall panel, and comprises a vertically lifting lifting push rod 21 and a lifting seat 22; the lifting seat 22 is connected to the telescopic end of the lifting push rod 21; in this embodiment, the lifting push rod 21 is an electric push rod; the fixed end of the lifting push rod 21 is connected to the right wall panel 02; the top end of the lifting seat 22 is connected to the right end of the deflection correction roller 1; the printing medium 00 passes around the upper side of the deflection correction roller 1; the lifting mechanism The vertical extension of the telescopic end of the lowering push rod 21 acts on the lifting seat 22, and the lifting seat 22 pushes the right end of the correcting roller 1 to rise; when the right end of the correcting roller 1 is higher than the left end of the correcting roller 1, the printing medium 00 passing through the upper side of the correcting roller 1 slides to the left side by itself; the telescopic end of the lifting push rod 21 retracts, and the lifting seat 22 descends; due to its own weight, the right end of the correcting roller 1 follows and descends; when the left end of the correcting roller 1 is higher than the right end of the correcting roller 1, the printing medium 00 passing through the upper side of the correcting roller 1 slides to the right side by itself; therefore, the lifting push rod 21 can be extended and retracted according to the deviation of the printing medium 00, and can change the position of the printing medium 00 passing through the upper side of the correcting roller 1, thereby achieving a correction effect.

[0016] Compared with the prior art, the printing medium 00 of the present invention realizes a folding at the deflection correction roller 1, and the deflection correction roller 1 can act on the printing medium 00 passing thereon alone; the deflection correction roller 1 can realize the up and down swinging of the right end around the left end through the lifting mechanism; the up and down swinging deflection correction roller 1 can act on the printing medium 00 thereon, so that the printing medium 00 can adjust its position autonomously to realize the deflection correction function; the deflection correction roller 1 of the present invention does not occupy horizontal space, can reduce the floor space of the equipment, and is conducive to the promotion of the equipment.

[0017] The deflection correction roller 1 is covered with a sleeve 11; the sleeve 11 rotates with the deflection correction roller 1; the sleeve 11 is in direct contact with the printing medium 00, and the wear of the printing medium 00 is reduced by rotating to ensure the quality of the printed product.

[0018] A vertical long hole 021 is provided at the position where the right wall is penetrated by the deviation-correcting roller 1, so as to provide sufficient space for the vertical lifting of the right end of the deviation-correcting roller 1.

[0019] A sliding bearing 12 is coaxially mounted on the right end of the deviation correcting roller 1; the outer wall of the sliding bearing 12 slides with the side wall of the vertical long hole 021, so that the right end of the deviation correcting roller 1 is horizontally limited by the vertical long hole 021, ensuring the lifting stability of the right end of the deviation correcting roller 1, thereby ensuring the stability of the deviation correction adjustment effect.

[0020] The top of the lifting seat 22 is rotatably matched with a pressure bearing 221; the right end of the deviation correcting roller 1 is provided with an axial plane 13; the side of the pressure bearing 221 is slidably matched with the axial plane 13, thereby reducing the wear of the top of the lifting seat 22 and the right end of the deviation correcting roller 1.

[0021] A vertical guide rail 022 is provided directly below the vertical long hole 021 of the right wall panel 02; a guide block 222 engaged with the vertical guide rail 022 is provided on the side of the lifting seat 22; the vertical guide rail 022 cooperates with the guide block 222 to provide guidance for the extension and retraction of the telescopic end of the lifting push rod 21, thereby ensuring a stable correction and adjustment effect.

[0022] A photoelectric switch frame 3 is provided at the lower front side of the deviation correction roller 1; the photoelectric switch frame 3 is a horizontal U-shaped structure; the photoelectric switch 31 is embedded in the end of the opening end, facing the middle opening; the printing medium 00 passes through the middle opening of the photoelectric switch frame 3; a roller armor 4 is provided above the photoelectric switch frame 3; the two ends of the roller armor 4 are respectively rotatably matched with the left wall panel 01 and the right wall panel 02; the roller armor 4 is set at a position facing the opening of the photoelectric switch 31; the roller armor 4 ensures that the printing medium 00 passing through the roller armor 4 passes through the photoelectric switch frame 3; when the edge of the printing medium 00 exceeds the position of the photoelectric switch 31, the photoelectric switch 31 will send an electrical signal, and the lifting push rod 21 will start to move; in this embodiment, the photoelectric switch frame 3 is installed on the right wall panel 02, on the same side as the lifting mechanism, so the lifting push rod 21 should perform the action of extending the telescopic end, which can gradually shift the printing medium 00 to the left, and the edge of the printing medium 00 is restored to a state not exceeding the photoelectric switch 31, that is, the deviation correction is completed.

[0023] A roller B 5 is provided at the lower rear side of the deflection correction roller 1; the two ends of the roller B 5 are respectively rotatably cooperated with the left wall panel 01 and the right wall panel 02; the setting position of the roller B 5 is located below the vertical long hole 021; the printing medium 00 passes over the deflection correction roller 1, which can ensure that the printing medium 00 is in contact with the upper side of the deflection correction roller 1, and the deflection correction effect of the deflection correction roller 1 is better.

[0024] The working principle of this embodiment is as follows: the photoelectric switch frame 3 provides a reference for the action command of the lifting push rod 21; because the photoelectric switch frame 3 is arranged on the right wall panel 02; therefore, when the photoelectric switch 31 in the photoelectric switch frame 3 senses that the edge of the printing medium 00 passes through the sensing light emitted by the photoelectric switch 31, the photoelectric switch 31 sends an electrical signal; because the lifting push rod 21 is also arranged on the right wall panel 02, after the photoelectric switch 31 sends an electrical signal, the telescopic end of the lifting push rod 21 extends outward, lifts the lifting seat 22, and pushes the right end of the deflection correction roller 1, so that the right end of the deflection correction roller 1 swings upward; when the right end of the deflection correction roller 1 is higher than the left end of the deflection correction roller 1, the printing medium 00 passing around the deflection correction roller 1 deviates to the left side for deflection correction.

[0025] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, and the similarities are not repeated here. The differences are as follows: a roller C 6 is provided above the roller B 5, and its two ends are respectively rotatably matched with the left wall panel 01 and the right wall panel 02; after the printing medium 00 is connected to the lower side of the roller B 5, it is connected to the upper side of the roller C 6; the roller C 6 can increase the wrap angle of the printing medium 00 on the roller B 5, thereby increasing the force of the roller B on the printing medium 00, and can assist in improving the correction effect of the correction roller 1 on the printing medium 00.
