[0013] A method for repairing ancient books, comprising the following steps:

[0014] (1) The ancient book page to be repaired is placed on a paper placing platform. The paper placing platform is moved up to its position under the drive of two lifting linear modules. Then, the controller turns on the light source on the paper placing platform, and uses the image scanning mechanism to scan the ancient book page to be repaired. The position and outline of the damaged hole on the ancient book page to be repaired are collected, and the thickness of the repair paper required for the damaged hole is determined by the light transmittance.

[0015] (2) According to the contour of the damaged hole, the rack drive motor is driven, and the active gear on the rack drive motor drives the annular rack to rotate, and the annular rack drives the bottom cover to rotate. When the bottom cover rotates, the guide rods on the blades are subjected to the tangential force of the rotation, so that each guide rod moves synchronously in the corresponding strip guide hole, thereby driving multiple blades to move synchronously, so that the opening of the material discharge control blade assembly is opened, and the size of the opening of the material discharge control blade assembly is smaller than the size of the damaged hole. At the same time, the XY axis linear module drives the glue spraying mechanism to spray glue on the damaged hole on the ancient book page to be repaired;

[0016] (3) After the glue spraying is completed, the XY axis linear module drives the paper fiber feeding mechanism to move to the top of the damaged hole, and starts the paper fiber delivery pump to send the paper fiber bundle into the feeding channel of the paper fiber feeding mechanism. After being scattered and combed by multiple paper fiber combing pin wheels in the feeding channel, the dispersed paper fibers are finally output from the opening of the feeding control blade assembly and evenly stacked at the damaged hole, and gradually transition to the edge of the damaged hole to obtain a patch paper with a thinner edge and rough edges. The feeding amount of paper fiber is controlled according to the thickness of the patch paper required to repair the damaged hole. After the feeding is completed, the controller starts the roller pressing motor, and the roller pressing motor drives the pressing roller to flatten the stacked paper fibers and wait for the glue to solidify, thus completing the ancient book repair operation.

Upper combing needles are arranged on the V-shaped inclined inner side wall of the primary feeding channel, and lower combing needles are arranged on the two side walls of the secondary feeding channel and adjacent to the secondary feeding port. First, the paper fibers are scattered, combed and screened in the first stage by the two primary paper fiber combing needle wheels rotating in the opposite direction and the upper combing needles. The fallen paper fibers are then scattered and combed in the second stage by the secondary paper fiber combing needle wheels. The paper fibers that continue to fall are finally scattered and combed in the third stage by the tertiary paper fiber combing needle wheels and the lower combing needles to obtain dispersed paper fibers.

[0018] Advantages of the present invention:

[0019] (1) The present invention is provided with a paper fiber feeding mechanism, which is used to break up and comb the paper fibers so that the fallen paper fibers will not agglomerate and can be stacked to form a patching paper with a thin edge and rough edges. This paper patching structure is used to accurately repair the damaged parts of the ancient books while maintaining the original appearance and texture of the ancient books;

[0020] (2) The present invention is provided with a paper placing platform facing the image scanning mechanism, and a light source is provided on the paper placing platform, which can collect the position and outline of the damaged hole on the ancient book page to be repaired, and judge the thickness of the repair paper required for the damaged hole by the transmittance. The paper fiber feeding mechanism is provided with a feeding control blade component, and the feeding control blade component is used to control the size of the bottom opening of the paper fiber feeding mechanism to be smaller than the size of the damaged hole, so that when the paper fibers are stacked, the paper fibers gradually transition to the edge of the damaged hole, so that a repair paper with a thin edge and rough edges can be obtained, and the feeding amount of the paper fibers is effectively controlled so that the thickness of the repair paper meets the thickness requirement of the repair paper. The entire paper repair process is automatically controlled, so as to realize the rapid and accurate repair of the damaged parts of the ancient book, while maintaining the original appearance and texture of the ancient book;

[0021] (3) The present invention is provided with an XY axis linear module and two lifting linear modules. The two lifting linear modules can drive the paper placing platform to move downward to achieve stable placement of the ancient book pages to be repaired, and drive the paper placing platform to move upward to realize the scanning and repair process. The XY axis linear module can drive the paper fiber feeding mechanism and the glue spraying mechanism to automatically complete the paper fiber feeding and glue spraying operations according to the position and contour of the damaged hole. The paper fiber feeding and glue spraying positions are accurate, which greatly improves the accuracy of ancient book repair;

[0022] (4) The paper fiber combing needle wheel of the present invention has the ability to grab and hold fibers, rub and shear against paper fibers, and achieve the combing of paper fibers. At the same time, due to the tooth gap design of the combing needles, the amount of paper fibers accommodated is relatively small, which helps to reduce the accumulation and congestion of paper fibers between the needle gaps. Moreover, under the influence of the rotating centrifugal force, the paper fibers are not easy to sink into the needle roots, thereby achieving the effect of breaking up and combing the paper fibers.

[0041] (1) The ancient book page to be repaired is placed on the paper placing platform 10. The paper placing platform 10 is moved up to the position under the drive of the two lifting linear modules 5. Then the controller turns on the light source 101 on the paper placing platform, and uses the CCD image sensor 11 to scan the ancient book page to be repaired, collects the position and outline of the damaged hole on the ancient book page to be repaired, and judges the thickness of the repair paper required for the damaged hole by the light transmittance;

[0042] (2) According to the contour of the damaged hole, the rack drive motor 716 is driven, and the active gear on the rack drive motor 716 drives the annular rack 717 to rotate, and the annular rack 717 drives the bottom cover to rotate.

7. The method for repairing ancient books using the paper fiber repair device for ancient book repair according to claim 6, characterized in that: The specific steps include: (1) The ancient book page to be repaired is placed on a paper placing platform. The paper placing platform is moved up to its position under the drive of two lifting linear modules. Then, the controller turns on the light source on the paper placing platform, and uses the image scanning mechanism to scan the ancient book page to be repaired. The position and outline of the damaged hole on the ancient book page to be repaired are collected, and the thickness of the repair paper required for the damaged hole is determined by the light transmittance. (2) According to the contour of the damaged hole, the rack drive motor is driven, and the active gear on the rack drive motor drives the annular rack to rotate, and the annular rack drives the bottom cover to rotate. When the bottom cover rotates, the guide rods on the blades are subjected to the tangential force of the rotation, so that each guide rod moves synchronously in the corresponding strip guide hole, thereby driving multiple blades to move synchronously, so that the opening of the material discharge control blade assembly is opened, and the size of the opening of the material discharge control blade assembly is smaller than the size of the damaged hole. At the same time, the XY axis linear module drives the glue spraying mechanism to spray glue on the damaged hole on the ancient book page to be repaired; (3) After the glue spraying is completed, the XY axis linear module drives the paper fiber feeding mechanism to move to the top of the damaged hole, starts the paper fiber delivery pump to feed the paper fiber bundle into the feeding channel of the paper fiber feeding mechanism, and after being scattered and combed by multiple paper fiber combing pin wheels in the feeding channel, the dispersed paper fibers are finally output from the opening of the feeding control blade assembly and evenly stacked at the damaged hole, and gradually transition to the edge of the damaged hole to obtain a patch paper with a thinner edge and rough edges. The feeding amount of the paper fiber is controlled according to the thickness of the patch paper required to repair the damaged hole. After the feeding is completed, the controller starts the roller pressing motor, and the roller pressing motor drives the pressing roller to flatten the stacked paper fibers and wait for the glue to solidify, thus completing the ancient book repair operation.
