[0029] Combine the following Figures 1 to 5 The embodiment shown describes the technical solution of the utility model: wherein, Figures 1 to 4 As shown:

[0030] The utility model provides a tipping paper deviation correction device, comprising: a frame 1, a guide deviation correction wheel 2, a movable sleeve assembly 4 and an adjusting screw 3;

[0031] There are at least two guide correcting wheels 2 arranged along the axial direction of the adjusting screw 3, and the guide correcting wheel 2 is provided with a first internal threaded hole 201 along the axial direction;

[0032] The movable sleeve assembly 4 includes an outer sleeve 401 and an inner sleeve 402, and the outer sleeve 401 is sleeved on the inner sleeve 402 and rotatably mounted with the inner sleeve 402; the inner sleeve 402 is provided with a first internal thread along the axial direction, and the outer sleeve 401 is provided with a first external thread 4011 and a second external thread 4012 arranged opposite to each other along the axial direction, and the first external thread 4011 and the second external thread 4012 have the same specifications and are respectively screwed with the guide deviation correction wheel 2; the inner sleeve 402 is also coaxially fixed with a stop nut 4024;

[0033] The adjusting screw 3 passes through the inner sleeve 402 and is threadedly connected to the inner sleeve 402 , and the adjusting screw 3 is rotatably mounted on the frame 1 . The frame 1 is also provided with a guide rod arranged parallel to the adjusting screw 3 , and the guide rod passes through the guide correction wheel 2 .

[0034] The embodiment of the utility model provides a paper correction device. By installing the movable sleeve assembly 4 in combination with the guide correction wheel 2 and the adjusting screw 3 respectively, it is possible to adjust the clamping width of the guide correction wheel 2 while adjusting the position of the guide correction wheel 2, thereby meeting the application of different widths of kraft paper in production and manufacturing. Specifically, by configuring the movable sleeve assembly 4 as an outer sleeve 401 and an inner sleeve 402, and screwing the inner sleeve 402 with the adjusting screw 3, it is possible to clamp the anti-rotation nut 4024 with an external force to prevent the inner sleeve 402 from rotating with the adjusting screw 3 while rotating the adjusting screw 3, thereby achieving the axial movement of the inner sleeve 402; by sleeve-mounting the outer sleeve 401 on the inner sleeve 402 and rotatably connecting with the inner sleeve 402, it is possible to achieve that the outer sleeve 401 can move with the inner sleeve 402 and can also rotate itself. ; By providing the first external thread 4011 and the second external thread 4012 arranged opposite to each other on the outer wall of the outer sleeve 401, the guide correcting wheel 2 can move in opposite directions when the outer sleeve 401 rotates itself, thereby realizing the change of the clamping width of the guide correcting wheel 2; by setting the specifications of the first external thread 4011 and the second external thread 4012 to be the same, the guide correcting wheel 2 can be moved synchronously and at the same distance; by setting the guide rod, the movement of the guide correcting wheel 2 can be guided and its rotation can be prevented.

[0035] According to the tipping paper deviation correction device provided by the embodiment of the utility model, Figures 1 to 4 As shown, a third external thread 4021 is formed on at least one end of the inner sleeve 402 , and a locking nut 4022 is threadedly connected to the third external thread 4021 . The locking nut 4022 can restrict the outer sleeve 401 from rotating when tightened.

[0036] In this embodiment, the third external thread 4021 and the locking nut 4022 are provided to restrict the random rotation of the outer sleeve 401 and avoid displacement of the guide deviation correction wheel 2.

[0037] According to the tipping paper deviation correction device provided by the embodiment of the utility model, Figures 1 to 4 As shown, a limiting ring 4023 is provided at one end of the inner sleeve 402 away from the third external thread 4021 , and the limiting ring 4023 is rotatably connected to the inner sleeve 402 .

[0038] In the embodiment of the present application, a plurality of ball grooves 4025 are formed on the outer surface of the inner sleeve along the circumferential direction, and a plurality of ball grooves 4025 are formed on the inner wall of the corresponding outer sleeve along the circumferential direction, and a plurality of balls are arranged between the corresponding ball grooves 4025. Of course, a ball bearing can also be used to rotatably connect the two.

[0039] In this embodiment, the limit ring 4023 is coaxially fixed to one end of the inner sleeve 402 away from the third external thread 4021, and its end face can be ball-connected with the side end face of the outer sleeve 401 to reduce the friction between the two; at the same time, the setting of the limit ring 4023 can constrain the axial movement of the outer sleeve 401 on the inner sleeve 402, thereby ensuring the stability of the entire system, and when the locking nut 4022 is tightened, it is bound to give axial pressure to the outer sleeve 401, so the setting of the limit ring 4023 balances the pressure.

[0040] According to the tipping paper deviation correction device provided by the embodiment of the utility model, Figure 2 and Figure 5 As shown, it also includes a compression spring 8, which is sleeved on the outer sleeve 401 and located between the guide and deviation correcting wheels 2.

[0041] In this embodiment, the setting of the compression spring 8 can achieve a constant thrust to the guide correction wheel 2, so that there is a certain pressure between the guide correction wheel 2 and the first external thread 4011 and the second external thread 4012, thereby making it difficult for the outer sleeve 401 to rotate.

[0042] According to the tipping paper deviation correction device provided by the embodiment of the utility model, Figure 1 As shown, the adjusting screw rod 3 is coaxially fixedly connected with a passive gear 5 , the passive gear 5 is meshed with a driving gear 6 , and the driving gear 6 is coaxially fixedly connected with a driving motor 7 .

[0043] With this arrangement, automatic correction can be achieved without manual adjustment, which greatly improves the correction efficiency and saves labor costs; the drive motor 7 can be a stepper motor and is electrically connected to the control unit, which is electrically connected to the deflection detection module of the tipping paper. When the deflection detection module detects the deflection displacement of the tipping paper, the deflection angle is calculated, and the stepper motor is controlled to rotate a certain angle to finally correct the deflection. The control accuracy of this automatic mode can reach within 0.3mm.

[0044] According to the tipping paper deviation correction device provided by the embodiment of the utility model, Figure 4 As shown, a thumbwheel 4013 is coaxially fixedly connected to one end of the outer sleeve 401 away from the limiting ring 4023 , and the end surface of the thumbwheel 4013 is flush with the end surface of the outer sleeve 401 .

[0045] This arrangement can facilitate the operator to rotate the outer sleeve 401, thereby driving the guide correction wheel 2 to move; by setting the end face of the thumbwheel 4013 to be flush with the end face of the outer sleeve 401, the pressure area of ​​the locking nut 4022 can be increased, thereby achieving a better locking effect.

[0046] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0047] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
