[0002] In order to repeatedly record and edit paper books and periodicals, a scanner is generally used to scan the paper books and periodicals, store them in a computer, and then edit them.
[0003] When scanning a thread-bound book, the thread-bound book is usually opened and the text on the paper is scanned by a scanner. However, the scanning of the thread-bound book is usually inaccurate due to external wind or movement of the thread-bound book. In order to solve this technical problem, a pressing mechanism is usually required to press the corners of the paper. However, the current pressing mechanism usually presses the corners of the thread-bound book directly, so that there will inevitably be a bulge in the middle of the paper, resulting in uneven paper in the thread-bound book and prone to scanning errors.

The gears 15 are arranged to transmit the rotation, so that the rotating roller 11 and the rotating shaft 13 rotate in opposite directions.
[0032] There are three types of drive structures: This application can use any of the following drive structures:
[0033] The first driving structure: The driving structure includes a dual-axis motor 21 installed at the exact center of the base 1, and the two output shafts of the dual-axis motor 21 are fixed with screws 22. It should be noted that; the thread directions of the two screws 22 are opposite, and the two screws 22 are threaded with first threaded seats 23, and the two first threaded seats 23 are respectively fixed on the driving rod 5. Two parallel sliding rods 10 are symmetrically fixed to the inside of the base 1 about the screw 22, and two sliding sleeves 9 are slidably installed on each sliding rod 10. The two sliding sleeves 9 on the same side are respectively fixed to the ends of the driving rod 5. Through the setting of the sliding sleeve 9 and the sliding rod 10, the driving rod 5 is limited, thereby reducing the shaking of the driving rod 5 during the movement.
[0034] When in use; first turn on the dual-axis motor 21, the two output shafts of the dual-axis motor 21 respectively drive the screw rod 22 to rotate, and the screw rod 22 can drive the drive rod 5 to move during the rotation, so that each drive rod 5 drives the same pressure rod 8 to move through the clamping assemblies at both ends, thereby completing the work of driving the two pressure rods 8.
[0035] The second driving structure: the driving structure includes a motor 31 installed at one end of the base 1, and the output shaft of the motor 31 extends to the inside of the base 1 and is installed with a bidirectional lead screw 32, and the bidirectional lead screw 32 is symmetrically threaded with a second driving seat 33, and the two second driving seats 33 are respectively fixed on the driving rod 5, and a sliding rod 10 is symmetrically fixed about the bidirectional lead screw 32 inside the base 1, and two sliding sleeves 9 are slidably installed on the sliding rod 10, and the two sliding sleeves 9 on the same side are respectively fixed on the ends of the driving rod 5, and the setting of the sliding sleeve 9 and the sliding rod 10 plays a role in limiting the driving rod 5, thereby reducing the shaking of the driving rod 5 during the movement.
[0036] When in use, first turn on the motor 31. The output shaft of the motor 31 can drive the bidirectional screw 32 to rotate. The bidirectional screw 32 can drive the driving rod 5 to move through the two second driving seats 33, so that each driving rod 5 drives the same pressure rod 8 to move through the clamping assemblies at both ends, thereby completing the work of driving the pressure rod 8.
[0037] The third driving structure: The driving structure includes a bidirectional cylinder 41 installed at the center of the base 1, and the two telescopic ends of the bidirectional cylinder 41 are respectively installed with mounting seats 42, and the two mounting seats 42 are respectively fixed on the driving rod 5.
[0038] When in use, the two telescopic ends of the bidirectional cylinder 41 respectively drive the driving rod 5 to move, and each driving rod 5 drives the same pressing rod 8 to move through the pressing components at both ends.
[0039] There are two ways to clamp the assembly; this application can use any of the following methods:
[0040] The first clamping assembly: The clamping assembly includes a slide 61 fixed at the end of the driving rod 5, and a tension spring 63 is fixed inside the slide 61, a limiting protrusion 62 is fixed on the top of the tension spring 63, and the end of the pressure rod 8 extends to the inside of the slide 61 and is fixedly connected to the limiting protrusion 62.
[0041] When pressing the paper of the thread-bound book, first pull the pressure rod 8 upward, and the two ends of the pressure rod 8 drive the limiting protrusions 62 to move upward inside the slide 61. During the upward movement of the slide 61, the tension spring 63 can be pulled upward, so that the tension spring 63 changes from the original state to the stretched state. If the middle part of the pressure rod 8 moves to the upper part of the thread-bound book, the pressure rod 8 can be loosened, and the tension spring 63 loses the tension force. When the tension spring 63 loses the stretching force, it returns to the original state and pulls the pressure rod 8, so that the pressure rod 8 can drive the rotating roller 11 to move downward, and the paper of the thread-bound book can be pressed down by the rotating roller 11.
[0042] The second pressing assembly: The clamping assembly includes a fixed seat 71 symmetrically fixed to the end of the driving rod 5, and a fixed shaft 73 is fixed on the fixed seat 71, a rotating seat 72 is fixed to the end of the pressure rod 8, and the rotating seat 72 is rotatably installed on the fixed shaft 73. It should be noted that a torsion spring 74 is mounted on the fixed shaft 73, and an arc plate 75 is fixed to the inner bottom wall of the fixed seat 71 and the inner top wall of the rotating seat 72, and the two ends of the torsion spring 74 are respectively inserted into the arc plate 75. Through the setting of the arc plate 75, the torsion spring 74 is limited, thereby reducing the shaking or loosening of the torsion spring 74 during use.
[0043] When pressing the papers in the thread-bound book, the pressure rod 8 is bent outward, and the rotating seats 72 at both ends of the pressure rod 8 rotate on the fixed shaft 73. The rotating seats 72 can squeeze the torsion spring 74 during the rotation process. At this time, the torsion spring 74 changes from the original state to the compressed state. If the thread-bound book is placed between the two pressure rods 8, the pressure rod 8 is released, the torsion spring 74 loses the squeezing force and recovers from the compressed state to the original state and pushes the rotating seat 72, so that the rotating seat 72 drives the pressure rod 8 to rotate, and the papers in the thread-bound book are pressed down through the rotating roller 11 on the pressure rod 8.
[0044] Working principle:
[0045] When scanning a thread-bound book, first turn on the driving structure, and the driving mechanism drives the two driving rods 5 to move and adjust the distance between the two driving rods 5, so that the two driving rods 5 respectively drive the two pressing rods 8 to move to the middle position through the clamping assembly. After the two driving rods 5 are adjusted, the thread-bound book is opened and placed on the placement table 20, and then the pressing rod 8 is bent or pulled so that the pressing rod 8 is adjusted through the clamping assembly. Then the rotating roller 11 can be pressed on the paper surface in the thread-bound book, and the driving structure is turned on again. The two driving rods 5 are driven to move in the opposite direction through the driving structure, and the driving rod 5 drives the pressing rod 8 to move through the clamping assembly. When the pressing rod 8 drives the rotating roller 11 to move, since the rotating roller 11 contacts the paper in the thread-bound book, the rotating roller 11 can roll on the paper and flatten the paper.
[0046] If there are foreign matters in the thread-bound book, first loosen the butterfly bolt 17 so that the rotating shell 12 can drive the rotating shaft 13 to rotate on the pressure rod 8, so that the brush 14 on the rotating shaft 13 contacts the paper surface. At this time, the rotating roller 11 can drive the rotating shaft 13 to rotate in the opposite direction through the gear 15 during the rotation process, so that the rotating shaft 13 can clean the foreign matters on the paper during the reverse rotation process.
