[0001] The utility model relates to the technical field of collating machines, in particular to a page feeding mechanism of a collating machine. Background Art

[0002] At present, with the development of social economy, printing enterprises focus on improving the production efficiency of post-press binding process under the premise of ensuring quality. The binding speed of post-press binding equipment has generally increased to more than 10,000 books / hour, so the stability requirements of post-press binding equipment have been greatly improved. In the post-press binding process, the collating machine is the starting point of the entire binding line. It is a binding device that completes the process of stacking and assembling books in order of book pages or paper pages. Only when the book core with fast and accurate collating can be sent to the binder can a good book be produced. The stability of collating plays a key role in the production efficiency of the entire production line.

[0003] However, when the speed of the collating machine's posting is greatly increased, when the book labels enter the conveying channel from the page baffle, due to a certain height difference between the page baffle and the conveying channel, the high-speed moving book labels are prone to deviation, causing the collating machine to have unstable posting conditions such as book label position deviation, book label disorder or book label blocking the channel when the page is posted at high speed, affecting the stability of the collating process. Utility Model Content

[0006] As a further technical solution, one side of the first belt and the other side of the second belt have an inclined angle which is consistent with the inclined angle between the leaf-joining baffle and the conveying passage.

[0007] As a further technical solution, a page feed driven roller is provided to the upper right of the upper driven roller, and a page feed opening slightly facing upward is formed between the first belt and the second belt between the upper driven roller and the page feed driven roller.

[0008] As a further technical solution, the upper power roller and the lower power roller are respectively connected to the upper power gear and the lower power gear through power shafts with the same structure.

[0009] As a further technical solution, both the first belt and the second belt are round belts, so as to facilitate the line contact transmission of the signatures.

[0010] As a further technical solution, two fixed shafts located below the synchronous main wheel are fixed between the installation adjustment plate and the fixed plate, and the first synchronous driven wheel and the second synchronous driven wheel are rotatably connected to the outer circumference of the two fixed shafts.

[0019] like Figure 1 As shown, the utility model provides a page feeding mechanism of a collating machine, including a page feeding mechanism body 300 located between a page splicing baffle 100 and a conveying channel 200 of the collating machine. The page feeding mechanism body 300 is used to convey the bookmarks at the slightly higher page splicing baffle to the slightly lower conveying channel.

[0020] like Figure 2 and Figure 3As shown, in a preferred embodiment, the page feeding mechanism body 300 includes a mounting adjustment plate 6 connected to the frame of the collating machine, and the mounting adjustment plate 6 is connected to the fixed plate 10 through a plurality of pillars 13. A main power shaft 14 is rotatably connected between the mounting adjustment plate 6 and the fixed plate 10, that is, both ends of the main power shaft 14 are rotatably connected to the mounting adjustment plate 6 and the fixed plate 10 through a first bearing 12, and the first bearing 12 adopts a deep groove ball bearing 6001. A synchronous main wheel 11 is fixedly provided on the outer periphery of the main power shaft 14, and two fixed shafts 8 located below the synchronous main wheel 11 are fixedly provided between the mounting adjustment plate 6 and the fixed plate 10, and the first synchronous driven wheel 7 and the second synchronous driven wheel 9 are rotatably connected on the outer periphery of the two fixed shafts 8. The power mechanism provided in the collating machine is connected to the synchronous main wheel 11, the first synchronous driven wheel 7 and the second synchronous driven wheel 9 through a synchronous belt, thereby driving the rotation of the main power shaft 14.

[0021] In a preferred embodiment, the driving gear 15 is connected to one end of the main power shaft 14 near the mounting adjustment plate 6, and the upper power gear 4 and the lower power gear 5 on the same side as the driving gear 15 are rotatably connected to one side of the mounting adjustment plate 6, the upper power gear 4 and the lower power gear 5 are meshingly connected, and the lower power gear 5 is meshingly connected to the driving gear 15, and the upper power gear 4 is not connected to the driving gear 15. Therefore, when the main power shaft 14 drives the driving gear 15 to rotate, the speed of the driving gear 15 and the lower power gear 5 is accelerated at a speed of 10:3, and the lower power gear 5 drives the upper power gear 4 to rotate, so that the lower power gear 5 and the upper power gear 4 rotate clockwise and counterclockwise respectively.

At the same time, the first belt 17 and the second belt 24 are preferably round belts, so as to facilitate the line contact of the book signature for transmission and prevent the book signature from being adhered to the belts.

[0024] In a preferred embodiment, a page feed driven roller 102 is provided at the upper right corner of the upper driven roller 101, and a page feed port 22 with an opening slightly facing upward is formed between the first belt 17 and the second belt 24 between the upper driven roller 101 and the page feed driven roller 102, so that book signatures can enter from the page feed port 22 to be transported between the first belt 17 and the second belt 24, and a page outlet 23 is provided between the first belt 17 and the second belt 24 on a side away from the page feed port 22, and book signatures enter the conveying channel 200 from the page outlet 23.
