[0002] This machine is a device that uses hot melt adhesive to stick and bind paper, plastic, leather, etc. mechanically. It can bind the prepared book core and cover together in a fully automatic or semi-automatic way. It is widely used.

[0003] Before the book blocks in a perfect binding machine are glued to the covers, the covers and book blocks need to be aligned synchronously, i.e., the covers are aligned with the book clamps. In traditional perfect binding machines, the synchronization between the push gauge and the book clamps is mostly achieved through mechanical synchronization, i.e., the push gauge and the book clamps are synchronized through matching mechanical transmission ratios, and the power comes from the same main motor.

[0004] This inevitably leads to mechanical errors, such as errors caused by gear transmission, errors caused by chain length extension, etc. As the equipment works for a long time, these errors will gradually accumulate and become larger, causing the cover to be misaligned with the book block, affecting the binding quality of the book. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a book binding machine with a synchronous revision function, which can automatically correct the error between the cover and the book block and improve the binding quality of the book.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Please refer to Figures 1 to 6 A perfect binding machine with synchronous revision functionality primarily comprises a main frame 1, a book clamping device located on the frame, and a gauge pushing device. The book clamping device comprises a main motor 21, a main transmission mechanism, a secondary transmission mechanism, a book clamp 25, and a running track 26, along which the book clamp 25 moves. The gauge pushing device comprises a gauge pushing frame, a gauge pushing device 32, and a workbench located on the gauge pushing frame. The gluing and bonding components on the workbench are not described in detail in this embodiment.

[0035] In order to achieve synchronous positioning, this embodiment provides a separate push gauge servo motor 31 and two groups of chain transmission mechanisms linked to the output shaft of the push gauge servo motor 31 on the push gauge frame. Each group of chain transmission mechanisms has a chain 33, and each push gauge 32 is evenly distributed on the corresponding chain 33. The cover is pushed to move by the two push gauges 32, which is more stable and reliable.

[0036] Furthermore, to achieve synchronous positioning, this embodiment also includes a first sensor 61 for monitoring the position of the push gauge 32 and a second sensor 62 for monitoring the position of the book clamp 25 on the workbench. The first and second sensors 61, 62 can be infrared sensors, photosensors, or other sensors capable of determining the position of the push gauge 32, though this embodiment does not specifically limit these. Both sensors are arranged along the direction of travel of the push gauge 32, with the spacing between the first and second sensors greater than the length of the book clamp 25. Thus, the two sensors can monitor the positions of the book clamp 25 and the push gauge 32, calculate the difference, and then feed this information back to the push gauge servo motor 31. The push gauge servo motor 31 adjusts its transmission ratio with the main motor 21 to eliminate errors and achieve synchronization.

[0037] Furthermore, to improve the reliability of cover transport and reduce the possibility of skew, this embodiment provides a front side gauge 34 and a rear side gauge 35 on the workbench. Both the front side gauge 34 and the rear side gauge 35 are linear structures and are located on either side of the gauge pusher 32. Limiting slots 36 are provided on the first side of the front side gauge 34 facing the rear cabinet and on the side of the rear side gauge 35 facing the front side gauge 34. When the cover is pushed forward by the gauge pusher 32, both sides are stuck in the limiting slots 36.

[0038] In this embodiment, the pusher 32 is configured in an L-shaped structure and fixedly connected to the side of the chain 33, which facilitates installation and increases the contact area for pushing the cover. A slideway is also provided on the workbench to prevent the pusher 32 from deviating, thereby improving the reliability of this embodiment.

[0039] Furthermore, to precisely control the speed of the book clamp 25, the main transmission mechanism in this embodiment comprises a sequentially connected gear transmission box 231, a driving shaft 232, and a driving wheel 234. An encoder 235 is positioned above the driving wheel 234, and a bracket 236 is provided on the main frame 1 for securing the encoder 235. The encoder 235 is connected to the driving shaft 232 via a coupling for signal exchange. The secondary transmission mechanism comprises a driven wheel 24, which is connected to the driving wheel 234 via a transmission chain 237 to enable the operation of the book clamp 25.

[0040] To improve the operational stability of the book clamp 25, a connecting base 41 and a clamping base 42 are provided. The back of the connecting base 41 is fixedly connected to the chain 33, and a positioning rod 43 is provided on the side of the clamping base 42 facing the connecting base 41. The two ends of the positioning rod 43 are connected to the clamping base 42, and a positioning pulley 49 is provided in the middle of the positioning rod 43. An annular positioning frame 48 is provided on the main frame 1. The positioning pulley 49 is located on the side of the annular positioning frame 48 facing away from the clamping base 42 and is in rolling connection with the annular positioning frame 48. This design ensures that the operating position of the book clamp 25 is consistently maintained, reducing the impact of changes in the transmission chain 237 on it, and indirectly improving production quality.

[0041] Because the book clamp 25 needs to turn during operation, this embodiment is equipped with positioning racks 44 on both sides of the positioning rod 43. The clamping seat 42 is equipped with a fixed gear 45 that meshes with the racks. The two fixed gears 45 are connected and coaxially arranged by a connecting rod 46, and the connecting rod 46 is equipped with a positioning torsion spring 47. An elastic limiting mechanism is provided for the positioning pulley 49, allowing for unloading or buffering during turning or shaking. The positioning torsion spring 47 then quickly resets the positioning pulley 49, reducing rigidity damage to the positioning rod 43 and other structures.

[0042] At the same time, this embodiment provides a one-to-one balance bar between the two sets of pushers 32 to monitor the synchronization between the two chains 33 and promptly detect any asynchrony between the two chains 33. Therefore, both ends of the balance bar 51 must be fixedly connected to the corresponding pushers 32. A balance plate 52 is then fixed to the center of the balance bar 51, perpendicular to the motion trajectory of the pushers 32. A third sensor 63 is also provided on the workbench to monitor the tilt angle of the balance plate 52. This tilt angle is used to determine whether the two chains 33 are operating synchronously. The third sensor 63 can also be an infrared or photosensitive sensor, which, through two sampling operations, calculates whether the distance between itself and two points on the balance plate 52 is within a reasonable error.

[0043] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
