Description

Technical Field

[0001] The present invention relates to the technical field of wire binding machines, and more precisely, to a wire binding machine with a text fixing device. Background Art

[0002] A binding machine is a special mechanical device for binding various paper materials such as documents, account books, ledgers, and bills in enterprises and institutions. In archive management work, archive binding is an important link. The initial manual wire binding method was to use a wire awl to punch small holes and then use a crochet hook to pick up the binding wire one by one, and finally tie a knot manually for binding. During the binding process, it was necessary to forcefully pierce through the binding object, which was not only time-consuming but also labor-intensive, with low efficiency, and there were also significant limitations on the binding thickness. The binding machine has well solved this problem. A binding machine generally includes a frame, a table board, a text fixing device, a wire hooking device, and a punching device. The table board is installed on the frame, the text fixing device is connected to the table board, and after the text is placed on the table board, the text is positioned on the table board through the text fixing device. The text fixing device includes a pressure paper board and a positioning component. The pressure paper board is used to press the text on the table board, and the positioning component is used to position the pressure paper board. When the existing text fixing device is in use, it is necessary to manually lift the pressed pressure paper board, which is very inconvenient to operate. There are also mechanisms that can automatically lift the pressure paper board, but they have a complex structure. Not only is the assembly more troublesome, but they are also prone to damage, affecting the service life of the wire binding machine. Summary of the Invention
