Description

Method for fixing book cover and locking device

Technical field

The present invention relates to the field of book scanning device technology, and in particular, to a method for fixing a cover of a book file and a locking device.

Background technique

With the development and advancement of science and technology, scanners are an indispensable and important device in today's digital office systems. Scanners are available in a wide variety of formats, configurations, and types to enable automatic paper feed scanning. However, for documents such as book archives, it is necessary to manually or mechanically turn pages when scanning.

The fixing of the cover of a book archive in an automatic flip book scanner is an important step. If the cover is not fixed properly, it will affect the success of flipping pages. Especially when the fixed position is unstable, the cover will be turned back and the book files will be closed together, which will interrupt the scanning process and seriously affect the scanning efficiency of the book files.

At present, the method of fixing the cover is often pressed by a manual pressing plate, which can completely fix the cover but requires the operator to operate every time, and can not realize automatic and quick disassembly of the file file. At the same time, in the prior art, a method of bonding a book cover with a tape is also appeared. This method takes a long time to replace the tape because the tape cannot be recycled, which causes inconvenience to the fixing of the cover.

Summary of the invention

The invention provides a method for fixing a cover of a book file and a locking device. The method and the locking device provide a new fixed form of a book cover, which can effectively eliminate the low efficiency of the book cover and is inconvenient to fix. defect.

The method for fixing a book cover of a book and the locking device provided by the present invention solve the problem by the following technical points: a locking device for a book cover, comprising a cover placing plate, and a tape winding mechanism, the tape winding mechanism The utility model comprises a tape winding shaft, a tape roll mounting shaft and a motor connected to the tape winding shaft, wherein the motor is used for driving the tape winding shaft for mounting the tape roll, and the tape winding shaft is used for pulling release The tape is wound around the tape loop, and during the tape release process, the tape passes over the support surface of the cover placement plate.

Specifically, the above tape roll mounting shaft is used for mounting a roll of tape, and the above tape winding shaft is used for directly winding the tape released by the tape roll or for mounting the tape wheel for winding the tape, directly on the tape winding shaft When the tape is wound, the tape drawn from the tape roll is directly wound on the tape winding shaft, and when the tape winding shaft is used to mount the tape wheel, the tape winding shaft is used to provide torque to the tape wheel, and the above tape is wound around the shaft. The power comes from the motor. The above tape roll continues to release the tape under the tensile stress of the taken-out tape, and the release of the tape can be achieved by the tape roll mounting shaft rotation, the tape winding tape roll mounting shaft rotation, and the like. Since the tape is wound from the tape to the tape winding axis, the path passes through the support surface of the cover placement plate. Thus, the side of the tape with the adhesive is facing the cover of the book or the file, the side of the tape without the adhesive is facing the support surface of the cover placement plate, so that the adhesive on the tape is not bonded to the cover or Although the adhesive is still sufficient, the cover of the book or file can be bonded to the adhesive layer by applying pressure to the side of the adhesive on the cover. At this time, the motor If you stop working, books or files with a fixed cover can be used for scanning. When the scanning is completed to remove the adhesive relationship between the tape and the cover, if the corresponding tape segment does not have sufficient adhesive ability, the motor works, and the adhesive tape segment is not pulled away from the work surface of the cover placement plate, and the new one is The tape section is added to the support surface of the cover placement plate as a new bonded working section, and the motor stops rotating to prepare for the next cover bond.

In the above locking device, after the starting end of the tape roll is wound on the tape winding shaft, the tape at the back end of the support surface of the cover placing plate can be sequentially used as a working segment for bonding and fixing the cover of the book file, in the process. It is not necessary to manually replace the tape section to complete the cover bonding and fixing, so that the fixing efficiency of the book cover can be effectively improved.
