However, the paper is prone to shifting at the entrance of the correction structure from the unwinding device. The aforementioned device does not have a correction structure at the entrance, causing the paper to shift at this initial stage, which greatly increases the difficulty of subsequent correction operations and easily leads to continuous printing defects. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing paper is prone to shifting at the entry point of the paper from the unwinding device into the correction structure. The aforementioned devices do not have a correction structure at the entry point, which causes the paper to shift at this initial stage, greatly increasing the difficulty of subsequent correction operations and easily leading to continuous printing defects. Therefore, this invention proposes an automated correction structure suitable for digital printing equipment.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3 An automated correction structure suitable for digital printing equipment includes a correction frame 1 and a correction roller 2. The correction roller 2 is located in the middle of the inner wall of the correction frame 1. An auxiliary roller 3 is rotatably connected to the entrance of the correction frame 1. A drive motor 4 is fixedly connected to the outer wall of the correction frame 1. The drive motor 4 is connected to a rubber wheel 5 through the entrance correction structure. A trigger wheel 6 is provided between the correction roller 2 and the auxiliary roller 3. An infrared sensing component 7 that can adjust the distance according to the paper size is provided at the entrance of the correction frame 1.

[0021] It should be noted that the specific models and specifications of the drive motor 4, sensor 12, and mobile infrared sensor 17 are determined based on the actual specifications of the device. The specific selection and calculation methods are based on existing technologies in this field, and therefore will not be elaborated upon.

[0022] Furthermore, the inlet correction structure includes a lead screw 8, a slide rod 9, and a moving wheel 10. The lead screw 8 is rotatably connected to the inner wall of the correction frame 1, the slide rod 9 is fixedly connected to the inner wall of the correction frame 1, and the moving wheel 10 is slidably connected to the middle end of the slide rod 9.

[0023] The entry correction structure is achieved by starting the drive motor 4, which drives the lead screw 8 to rotate. The lead screw 8 drives the moving wheel 10 to move back and forth on the slide rod 9. The moving wheel 10 drives the rubber wheel 5 to move, and the rubber wheel 5 moves the paper with the help of the rubber surface to correct the position.

[0024] Furthermore, the lead screw 8 is threadedly connected to the movable wheel 10, the rubber wheel 5 is rotatably connected to the outer surface of the movable wheel 10, and one end of the lead screw 8 passes through the outer wall of the correction frame 1 and is fixedly connected to the output end of the drive motor 4.

[0025] The auxiliary roller 3 is positioned directly above the inlet correction structure and works in conjunction with the rubber wheel 5 to allow the paper to pass smoothly between them.

[0026] Furthermore, a connecting cylinder 11 is fixedly connected to the inner wall of the correction frame 1. The connecting cylinder 11 is fixedly connected to the trigger wheel 6. Two sets of sensors 12 are provided at the top of the trigger wheel 6, and the sensors 12 are provided with connecting wires 13.

[0027] The sensor 12 is configured as an external sensor and an internal sensor. When the paper is being corrected, when one end of the paper reaches between the external sensor and the internal sensor, it can trigger and control the drive motor 4 to stop running, so as to prevent the paper from being over-corrected. The specific installation position is adjusted according to the paper's entry direction.

[0028] Furthermore, the infrared sensing component 7 includes a slide 15, a bidirectional lead screw 16, a movable infrared sensor 17, and a drive end 18. The slide 15 is located at the top of the entrance of the correction frame 1. The bidirectional lead screw 16 is rotatably connected to the slide 15, and the movable infrared sensor 17 is slidably connected to the slide 15.

[0029] The infrared sensing component 7 is inserted into the drive end 18 by a worker using a tool. The drive end 18 is then rotated, which drives the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 causes the moving infrared sensors 17 on both sides to move closer or further apart. This allows the distance between the moving infrared sensors 17 to be adjusted according to the size of the paper, greatly increasing the practicality of the correction structure.

[0030] Furthermore, the bidirectional lead screw 16 is threadedly connected to the moving infrared sensor 17. One end of the bidirectional lead screw 16 passes through the outer wall of the correction frame 1 and is connected to the drive end 18, which is located on the outer wall of the correction frame 1.

[0031] The moving infrared sensor 17 is connected to the drive motor 4 via an electrical signal. When the paper is in the correct position, the drive motor 4 will not be triggered. When the position is deviated, the drive motor 4 will be activated to drive the paper to correct its deviation.

[0032] Working principle: When using this device, first adjust the distance between the moving infrared sensors 17 according to the size of the paper. The worker inserts a tool into the drive end 18 and then rotates the drive end 18. The drive end 18 drives the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 causes the moving infrared sensors 17 on both sides to move closer or further apart. Then, when the paper deviates when entering the correction structure, the moving infrared sensors 17 are triggered, starting the drive motor 4. The drive motor 4 drives the lead screw 8 to rotate. The lead screw 8 drives the moving wheel 10 to move back and forth on the slide bar 9. The moving wheel 10 drives the rubber wheel 5 to move. The rubber wheel 5 uses the rubber surface to move the paper to correct the position, thereby preventing the paper from deviating at the entrance. This reduces the difficulty of subsequent correction operations and greatly reduces the probability of continuous printing defects.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
