Description

Technical Field

[0001] The invention relates to the technical field of printing equipment, in particular to a synchronous regulating device for a glue binder which can be adjusted online based on an angular difference differential gear train. Background Art

[0002] The binding line is an important equipment for achieving automation in post-press processing. It is usually composed of multiple functional modules, including a collating machine, a high-speed binding machine, a three-sided book trimmer, and a transmission machine for linkage. Among them, the high-speed binding machine is the core equipment for book binding. It completes the clamping and transportation of the book core through the book clamp, and completes the binding process after rough milling, fine milling, grooving, gluing, and pasting the cover. In this process, ensuring the precise synchronous movement between the book clamp and the cover transportation mechanism (such as the push gauge) is the key issue to ensure the accuracy of cover pasting and improve product quality.

[0003] The current cover pasting process usually uses a push gauge to push the cover, and transfers the cover to the bottom of the book core clamped by the book clamp, so that the book core and the cover move synchronously before pasting. To this end, the first problem that needs to be solved is to ensure that the book core clamped by the book clamp and the cover pushed by the push gauge maintain an accurate synchronization relationship in relative position. However, the traditional mechanical synchronization adjustment method is complicated to adjust and requires multiple debugging through mechanical components. It cannot meet the real-time adjustment needs in the production process, and due to adjustment errors, it is easy to cause cover pasting deviations, affecting the processing quality. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a synchronous adjustment device for a binder which can be adjusted online based on an angular difference differential gear train, thereby solving the problem of synchronous movement and precise relative position adjustment between a book clamp and a push gauge of the binder.

[0015] Preferably, a bearing cover is provided between the output shaft and the input shaft, and a driving wheel bearing is fixedly connected to the bottom of the bearing cover. The bearing cover and the driving wheel bearing rotate about the common axis of the output shaft and the input shaft. A planetary bevel gear rotates on the raised cylindrical outer wall at the bottom of the driving wheel bearing, and the planetary bevel gears are meshed with the output center wheel and the input center wheel.

[0016] Preferably, the gear transmission mechanism and the differential gear train mechanism are connected through the meshing between the driving bevel gear and the driven bevel gear.

[0022] 2. The present invention controls the planetary carrier in the differential gear train mechanism through the differential angle adjustment mechanism to achieve dynamic adjustment of the relative angle between the input shaft and the output shaft. By adjusting the rotation angle of the planetary carrier online, the relative rotation angle between the output shaft and the input shaft changes, so as to achieve the purpose of quickly correcting the relative position of the two. According to the speed synthesis formula of the differential gear train, the relative rotation angle of the output shaft is twice the rotation angle of the planetary carrier and is consistent with the direction of the planetary carrier. This relative position adjustment function effectively adapts to the processing requirements of book cores and covers of different specifications, and improves the adaptability and flexibility of the equipment.

This greatly reduces the downtime caused by adjustment, improves production efficiency, and reduces the workload of operators. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Please see attached Figure 1 and attached Figure 4 The embodiment of the present invention provides a synchronous adjustment device for a binding machine that can be adjusted online based on an angular difference differential gear train, comprising:

[0033] The three-dimensional box seat 2 is used as the basic carrier of the equipment to provide overall structural support and installation foundation;

[0034] The differential gear train mechanism 3 is installed on one side of the three-dimensional box seat 2 and is used to achieve motion synthesis and relative angle adjustment;

[0035] The gear transmission mechanism 1 is arranged on the top of the three-dimensional box seat 2 and is used to provide external power to the differential gear train mechanism 3;

[0036] The difference angle adjustment mechanism 4 is installed at the bottom of the three-dimensional box seat 2 and is used to adjust the relative position;

[0037] The angle difference adjustment mechanism 4 includes a servo motor 41 and a motor support plate 48. The servo motor 41 is fixed to one side of the gear transmission mechanism 1 through the motor support plate 48. The output end of the servo motor 41 is fixedly connected with an angle difference adjustment shaft 45. The internal thread of the angle difference adjustment shaft 45 is connected with a latch pin shaft 42. The raised cylindrical outer walls on both sides of the latch pin shaft 42 are slid with sliding pin sleeves 43. The outer wall of the sliding pin sleeve 43 is slid with a shift fork 44. A driving sprocket 46 is fixed to the output end of the servo motor 41. A driven sprocket 47 is fixed to the outer wall of the angle difference adjustment shaft 45. The driving sprocket 46 and the driven sprocket 47 are meshed with the same chain to realize synchronous transmission.

[0038] The angle difference adjustment mechanism 4 provides precise driving force through the servo motor 41, and stably fixes it on the three-dimensional box seat 2 through the motor support plate 48 to ensure the stability of operation. The servo motor 41 drives the angle difference adjustment shaft 45 to rotate, and the angle difference adjustment shaft 45 is threadedly connected with the latch pin shaft 42, so that the latch pin shaft 42 moves smoothly through the sliding pin shaft sleeve 43, driving the shift fork 44 to adjust the angle. The shift fork 44 is fixedly connected to the driving wheel bearing 34, and the movement of the shift fork 44 is controlled by the servo motor 41, so that the driving wheel bearing 34 changes its angle, thereby affecting the relative angle between the output shaft 31 and the input shaft 38 of the differential gear train mechanism 3. In this way, the servo motor 41 is controlled to achieve precise adjustment of the driving wheel bearing 34, so that the angle change of the output shaft 31 meets the requirements, and then complete the synchronous adjustment of the book clamp and the push gauge, while supporting rapid online adjustment to improve the flexibility and precision of the equipment.

[0039] Please see attached Figure 2 The gear transmission mechanism 1 includes an upper vertical shaft 16, which is fixed on the top of the three-dimensional box seat 2. A sleeve seat 13 is rotated on the outer wall of the upper vertical shaft 16. An overload clutch 11 is rotated on the outer wall of the sleeve seat 13. The overload clutch 11 is fixed at one end of the sleeve seat 13. A driving gear 14 is fixed to the bottom of the outer wall of the sleeve seat 13. An input sprocket 12 is fixed to the top of the outer wall of the sleeve seat 13. A vertical shaft 17 is arranged on one side of the upper vertical shaft 16. The vertical shaft 17 rotates inside the three-dimensional box seat 2. A driving bevel gear 18 is fixed to one end of the vertical shaft 17, and a driven gear 15 is fixed to the other end of the vertical shaft 17. The driven gear 15 is meshed with the driving gear 14.

[0040] Specifically, the gear transmission mechanism 1 serves as the power input and transmission part of the device, and uses the input sprocket 12 to introduce external power into the system to ensure smooth power transmission when the device is started. The power passes through the sleeve seat 13 and is provided with overload protection through the overload clutch 11 fixed thereto to prevent damage to the device due to sudden load during mechanical operation. Subsequently, the power is converted and transmitted through the meshing of the driving gear 14 and the driven gear 15 to achieve power direction conversion. The power after gear meshing is guided to the vertical shaft 17 and transmitted to the driven bevel gear 37 of the differential gear train mechanism 3 through the driving bevel gear 18, and the rotational power is accurately input to the input shaft 38 of the differential gear train mechanism 3, thereby ensuring that the power is efficiently and stably transmitted to the differential gear train mechanism 3, which not only ensures the smoothness of the power path, but also provides protection for the equipment through the overload clutch 11, thereby extending the life of the device.

[0041] Please see attached Figure 3 and Figure 5 and attached Figure 6The differential gear train mechanism 3 includes an output shaft 31 and an input shaft 38, both of which rotate inside the three-dimensional box seat 2. An output center wheel 32 is fixed to one end of the output shaft 31, and an input center wheel 36 is fixed to the outer wall of the input shaft 38. One end of the input shaft 38 is fixed inside the output center wheel 32. A bearing cover 33 is arranged between the output shaft 31 and the input shaft 38. A driving wheel bearing 34 is fixedly connected to the bottom of the bearing cover 33. The bearing cover 33 and the driving wheel bearing 34 rotate about the common axis of the output shaft 31 and the input shaft 38. A planetary bevel gear 35 rotates on the outer wall of the cylindrical protrusion at the bottom of the driving wheel bearing 34. The planetary bevel gear 35 is connected to the output center wheel 32 and the input center wheel 36 are meshed, the gear transmission mechanism 1 is connected to the differential gear train mechanism 3 through the meshing between the active bevel gear 18 and the driven bevel gear 37, the differential gear train mechanism 3 is connected to the differential angle adjustment mechanism 4 through the fixed connection between the driving wheel bearing 34 and the shift fork 44, the output shaft 31 is connected to the push gauge chain, the input shaft 38 is connected to the book clamp chain transmission, the output shaft 31 and the input shaft 38 are synchronously adjusted to realize the synchronous movement of the book clamp and the push gauge, when the driving wheel bearing 34 stops rotating, the input shaft 38 and the output shaft 31 have the same rotation speed and opposite direction, when the input shaft 38 stops, the rotation angle of the output shaft 31 is twice the rotation angle of the driving wheel bearing 34, and the directions are the same.

[0042] Specifically, the differential gear train mechanism 3 serves as the core of power allocation, and the power transmitted by the gear transmission mechanism 1 is input into the system through the input shaft 38. The input shaft 38 is fixedly connected to the input center wheel 36, and drives the input center wheel 36 to mesh with the planetary bevel gear 35 when rotating. The driving wheel bearing 34 serves as an intermediate bridge in the system, and can rotate around the common axis of the input shaft 38 and the output shaft 31, driving the planetary bevel gear 35 to further mesh with the output center wheel 32, so that the power forms a dynamic synthesis relationship between the input shaft 38 and the output shaft 31. When the speed of the driving wheel bearing 34 changes, the speed and angle of the output shaft 31 are also changed accordingly. In this way, the power distribution and synthesis are realized through the mutual meshing of the input center wheel 36, the planetary bevel gear 35 and the output center wheel 32, and the relative angle between the output shaft 31 and the input shaft 38 is accurately adjusted through the controllable rotation of the driving wheel bearing 34, providing support for subsequent synchronous adjustment.

[0043] Working principle: External power is input into the gear transmission mechanism 1 through the input sprocket 12, and the power is transmitted to the overload clutch 11 through the sleeve seat 13, and then transmitted to the vertical shaft 17 through the meshing between the driving gear 14 and the driven gear 15. The vertical shaft 17 drives the driving bevel gear 18 to mesh with the driven bevel gear 37 in the differential gear train mechanism 3, and transmits the power to the input shaft 38. The input shaft 38 is fixedly connected to the input center wheel 36 of the differential gear train mechanism 3. After the power is input, the differential gear train mechanism 3 forms a synthetic relationship between the rotation speed of the input shaft 38, the rotation speed of the driving wheel bearing 34 and the rotation speed of the output shaft 31 according to the principle of motion synthesis, so as to realize power distribution and angle adjustment. The differential angle adjustment mechanism 4 drives the angle difference adjustment shaft 45 to rotate through the servo motor 41, and the angle difference adjustment shaft 45 adjusts the rotation angle of the driving wheel bearing 34 through the shift fork 44 and the sliding pin sleeve 43. When the differential angle adjustment mechanism 4 keeps the driving wheel bearing 34 stationary, the input shaft 38 and the output shaft 31 have the same rotation speed but opposite directions; when the input shaft 38 remains stationary, the servo motor 41 adjusts the angle of the driving wheel bearing 34 so that the angle change of the output shaft 31 is twice the angle of the driving wheel bearing 34. Finally, the power of the output shaft 31 is transmitted to the push gauge chain through the sprocket. At the same time, the input shaft 38 is connected to the book clamp chain through the gear transmission mechanism 1 to achieve synchronous movement between the book clamp and the push gauge. When the relative position of the book clamp and the push gauge needs to be adjusted, the angle of the driving wheel bearing 34 is adjusted through the differential angle adjustment mechanism 4 to change the relative angle between the output shaft 31 and the input shaft 38 to ensure that the two can move synchronously at a suitable relative position to complete the online adjustment function of the equipment. The speed synthesis formula of the motion synthesis part is as follows:

[0044] n out =(i+1)n H -in IN

[0045] Where: n out is the speed of the output center wheel 32; n H is the rotation speed of the driving wheel bearing 34; n IN is the speed of the input center wheel 36; i is the transmission ratio of the equivalent fixed axis gear train; n out A negative sign indicates a direction opposite to the positive direction.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
