Description

Technical Field

[0001] The utility model belongs to an important structure in the book processing process, in particular to a book turning mechanism. Background Art

[0002] The production process of a book is generally as follows: first, the binding design is carried out, then the pages and covers are printed, then the pages are sealed with glue, and then the book cover and the sealed pages are pasted together to form the final book product. After the book cover and the pages are pasted, many books, especially for hardcover editions, have a relatively large cover thickness. Therefore, it is necessary to further press the glue line. When some products need to press the glue line, an indentation needs to be pressed to ensure the stability of the glue between the book cover and the pages. When the book covers and books of existing books are glued, the books are placed horizontally. For example, application number 202320620478.9 discloses a book glue fixing device, which presses the glued pages and book covers with a pressing mechanism, and the book is placed horizontally. When the book needs to be processed with glue lines later, the book is manually converted to a vertical state, so that the glue line equipment can press the glue lines on the upper and lower sides of the book at the same time. Therefore, special manpower is required to flip the book, which consumes more manpower. Utility Model Content

[0014] Figure 2 The utility model is a schematic diagram of the structure of the driving device in the book turning mechanism. DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Reference Figure 1-2 The book turning mechanism comprises a frame 1, a turning frame 2, a connecting rod device 3 and a driving device 4. The driving device 4 is arranged on the frame 1 and comprises a rotating shaft 41. There are two connecting rod devices 3, which are respectively provided at two ends of the rotating shaft 41. The two connecting rod devices 3 are symmetrically arranged, and the two sides of the turning frame 2 are respectively connected to the two connecting rod devices 3.

[0017] In actual use, the turning frame 2 is a square fence structure, which is convenient for placing books. When the turning frame 2 is in a horizontal state, the book that has been initially fixed by gluing in the previous process falls horizontally onto the turning frame 2, and then rotates through the rotating shaft 41 of the driving device 4, driving the connecting rod device 3 to rotate accordingly, and the turning frame 2 is driven by the connecting rod device 3 to turn over, and can be rotated from a horizontal state to a vertical state, thereby switching the book from a horizontal state to a vertical state, which is convenient for the next process to perform glue line processing on both sides of the book.

[0018] The connecting rod device 3 includes a first connecting rod 31, a second connecting rod 32 and a third connecting rod 33. One end of the first connecting rod 31 is sleeved on the rotating shaft 41, the bottom end of the second connecting rod 32 is connected to the other end of the first connecting rod 31, one end of the third connecting rod 33 is connected to the middle part of the second connecting rod 32, and the other end is arranged on the frame 1, and the turning frame 2 is connected to the top end of the second connecting rod 32.

[0019] The second connecting rod 32 and the first connecting rod 31 can be connected by a pin shaft, so that the first connecting rod 31 can drive the second connecting rod 32 to rotate; by providing a third connecting rod 33, and the third connecting rod 33 is provided on the frame 1, the rotation of the second connecting rod 32 can be limited, so that when the first connecting rod 31 rotates with the rotating shaft 41, the turning frame 2 connected to the top of the second connecting rod 32 does not need to rotate a full circle, and the turning frame 2 can be switched from horizontal to vertical and then from vertical to horizontal in a cycle, thereby realizing continuous turning of books without manual turning of books, and the operation is convenient.

[0020] Among them, each connecting rod connection in the connecting rod device 3 can be connected by a pin shaft to facilitate the smooth rotation of each connecting rod. When the rotating shaft 41 rotates, it drives the first connecting rod 31 to rotate, and the second connecting rod 32 is driven to rotate accordingly through the first connecting rod 31, so that the flip frame 2 is driven to switch between the horizontal and vertical states through the second connecting rod 32. When the rotating shaft 41 rotates one circle, the flip frame 2 rotates from the horizontal state to the vertical state, and then returns to the horizontal state.

[0021] The book turning mechanism of the utility model further comprises a guide rod 5, which is rotatably connected with the frame 1, and a mounting groove is provided on the guide rod 5, and the guide rod 5 is located on both sides of the turning frame 2, and the two sides of the turning frame 2 are respectively matched with the corresponding mounting grooves. The side of the turning frame 2 is installed in the mounting groove, and at the same time, the length of the guide rod 5 is less than the length of the side of the turning frame 2 that matches with it, so that the turning frame 2 is rotated under the action of the second connecting rod 32, and can act on the guide rod 5, so that the turning frame 2 can move along the mounting groove while rotating with the guide rod 5, so as to facilitate the switching of the turning frame 2 between the horizontal and vertical states.

[0022] The driving device 4 also includes a motor 42, a driving shaft 43 and a transmission chain 44. The motor 42 is fixed on the frame 1, the driving shaft 43 is connected to the output shaft of the motor 42, a first sprocket 45 is sleeved on the driving shaft 43, a second sprocket 46 is sleeved on the rotating shaft 41, and the first sprocket 45 and the second sprocket 46 are connected through the transmission chain 44. Specifically, when the motor 42 is working, it drives the driving shaft 43 to rotate, the first sprocket 45 on the driving shaft 43 rotates synchronously, and then drives the second sprocket 46 to rotate under the action of the transmission chain 44, and the second sprocket 46 drives the rotating shaft 41 to transmit synchronously, so as to facilitate the connection rod device 3 to work through the rotating shaft 41.

[0023] The frame 1 is provided with a first mounting shaft 6, and the other end of the third connecting rod 33 is sleeved on the first mounting shaft 6, and the first mounting shaft 6 is located above the rotating shaft 41. Thus, by providing the first mounting shaft 6, the installation of the third connecting rod 33 is facilitated, and the third connecting rod 33 can be ensured to rotate around the first mounting shaft 6.

[0024] The frame 1 is provided with a second mounting shaft, the second mounting shaft being located above the first mounting shaft 6, and the guide rod 5 is mounted on the second mounting shaft. Similarly, by providing the second mounting shaft, the installation of the guide rod 5 can be facilitated, and the guide rod 5 can be conveniently rotated with the flip frame 2.

[0025] In actual use, in order to better turn the book, the book turning mechanism also includes an air nozzle 7, which is arranged on the frame 1 and corresponding to the turning frame 2. That is, when the book rotates to a vertical state with the turning frame 2, the high-pressure gas blown out by the air nozzle 7 after being connected to the outside acts on the side of the book close to the turning frame 2, so that the book rotates to a vertical state and gradually separates from the turning frame 2. Under the action of the high-pressure gas, the book always remains vertical, which is convenient for connection with the next process.

[0026] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
