Saddle stapler book feeding mechanism

Abstract

The invention discloses a book conveying mechanism of a saddle stitching machine. A book is conveyed to be between two large belt wheels along the upper surfaces of bearing sets after being cut by an upper cutter and a lower cutter, a horizontal press plate is further arranged above the bearing sets, and one end of the horizontal press plate is fixedly connected with a fixing seat through a support. When the horizontal press plate does not press down, the advancing resistance of the book is small, the book can reach an assigned position more easily, and the deformation of the first page of the book cannot be caused; when the horizontal press plate presses down, the bearing sets on the two sides of the lower face respectively are matched with an iron plate on the lower portion of the horizontal press plate, air in the book is discharged, the book is pressed flatly, the phenomena that the pages on the outer face of the cut sealing port of the book are long and the pages on the center of the cut sealing port of the book are short previously will not occur, and thus the production efficiency and the book processing quality of the saddle stitching machine are improved effectively.

Description

technical field [0001] The invention relates to a stapler, in particular to a book feeding mechanism of a saddle stapler. Background technique [0002] The saddle stitcher is mainly used to produce magazines, booklets, CD booklets and similar products. At present, the saddle stitch produced by Heidelberg, Germany is commonly used. The minimum production size of the equipment is 100*74mm, and the actual binding thickness is 4mm. For thicker instructions , some pages are up to 42 pages, and the size is 105*74mm. Since the width of the book has exceeded the lower limit of the actual binding thickness of the stapler, it is easy to fail to deliver the book in place when the book is delivered. The thickness exceeds the conventional size, and the staple of the book Afterwards, an arc appears, which affects the three-sided trimming of saddle stitching. After trimming, the length of the paper at the seal of the book is inconsistent, and the outer page is long and the center page is s...

Problems solved by technology

[0002] The saddle stitcher is mainly used to produce magazines, booklets, CD booklets and similar products. At present, the saddle stitch produced by Heidelberg, Germany is commonly used. The minimum production size of the equipment is 100*74mm, and the actual binding thickness is 4mm. For thicker instructions , some pages are up to 42 pages, and the size is 105*74mm. Since the width of the book has exceeded the lower limit of the actual binding thickness of the stapler, it is easy to fail to deliver the book in place when the book is delivered. The thickness exceeds the conventional size, and the staple of the book After the arc appears, the arc affects the three-sided trimming of the saddle stitching. After trimming, the length of the paper at the seal of the book is inconsistent, and the outer page is long and the center page is short.

[0003] In order to solve the above problems, such as figure 1 In the book feeding mechanism of the saddle stitcher shown, a small synchronous pulley is installed between the paper feed positioning synchronous pulley and the pressure plate, and a small synchronous belt is installed to connect the paper feed positioning synchronous pulley, which is driven by the paper feed positioning synchronous pulley. The belt runs synchronously with the paper feeding and positioning pulleys. I want to solve the problem that sometimes the book is not in place at the lower limit of the width, and can discharge the air in the book, press the book, and avoid the phenomenon that the outer page of the book is long and the center page is short, but in fact If the goal is not achieved, the air in the book must be discharged so that the outer pages of the book do not appear to be long and the center pages are short. The small belt must be pressed tightly. The big belt is driven, and the other side of the book is three small bearings without drive. When the book reaches the belt, because the stiffness of the paper is less than the resistance of the book, the first page of the book will be deformed, such as figure 2 shown
