Description

Technical Field

[0001] This utility model relates to the field of adhesive binding technology, specifically to a servo-controlled automatic lifting mechanism for a binding table. Background Technology

[0002] Currently, in post-press binding processing, there are two methods for producing thicker books: perfect binding line and hardcover binding line. Perfect binding line generally includes processes such as folding, collating, binding, cover wrapping, and trimming. Using this line for perfect binding is efficient and low-cost. However, the perfect binding line process requires adjustment of the printing table, but the existing adjustment device involves manually rotating the relevant transmission components, which is not only slow but also has poor control effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a servo-controlled automatic lifting mechanism for a printing table. It has a simple structure, is easy to operate, and can achieve fully automatic adjustment, making the adjustment faster and more accurate. It avoids the large errors that occur when adjusting manually, which affect the processing of book pages, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a servo-controlled automatic lifting mechanism for a tray, comprising a large base plate and a cam. Four linear bearing seats are fixed to one side of the large base plate by screws. Two corresponding linear bearing seats form a group, and each group of linear bearing seats is connected to a main lifting shaft via a linear bearing. A tray is fixed between the upper ends of the two main lifting shafts via a support plate. A lifting nut is threadedly connected to the middle position of each main lifting shaft. A lifting seat is provided between two lifting nuts, and the lifting seat is positioned relative to the lifting nut. The lifting seat is rotatably connected, with sprocket 1 fixed to the lower side of the two lifting nuts. A servo motor is mounted on one side of the lifting seat via a motor mount. Sprocket 2 is fixed to the output shaft end of the servo motor. Sprocket 2 and the two sprocket 1 are connected by a chain drive. A buffer is provided at the lower end of each lifting nut. When the cam rotates, it drives the lifting seat to move up and down. The cam is located between the lifting seat and the base plate. A sliding groove is provided on one side of the cam, and a roller needle bearing is provided on one side of the lifting seat. The roller needle bearing is located inside the sliding groove, and when the cam rotates, the roller needle bearing slides along the inside of the sliding groove.

[0005] Furthermore, the buffer component includes a lifting buffer spring, the upper end of which is connected to the lower end of the lifting nut via a thrust bearing, and a positioning sleeve is fixed to the lower end of the lifting buffer spring, which is fixed to the position corresponding to the main lifting shaft.

[0006] Furthermore, both the upper and lower sides of the lifting seat are connected to the lifting nut via thrust ball bearings, and a composite bearing is provided between the lifting seat and the lifting nut.

[0007] Furthermore, two tensioning sprocket assemblies are fixed on the left and right sides of the motor base, and the two tensioning sprocket assemblies tension the chains on both sides of the sprockets respectively.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the main shaft end of the external drive mechanism is fixedly connected to one side of the cam. The rotation of the external drive mechanism drives the cam to rotate. When the cam rotates, the sliding groove is at a different position from the rotation center, thereby driving the lifting seat to move up and down, thus moving the pressing table up and down for pressing. When the pressing table needs to be adjusted, the rotation of the servo motor can drive the second sprocket. Through the transmission of the second sprocket, the first sprocket and the chain, the two lifting nuts can be driven to rotate. When the lifting nuts rotate, the main lifting shaft can move up and down, thereby fine-tuning the up and down position of the pressing table. This servo-controlled automatic lifting mechanism for the pressing table has a simple structure and is easy to operate. It can achieve fully automatic adjustment, making the adjustment faster and more accurate, avoiding the large errors that affect the processing of pages when manually adjusting.

[0016] Please see Figure 1-5This utility model provides a technical solution: a servo-controlled automatic lifting mechanism for a tray, comprising a base plate 1 and a cam 2. Four linear bearing seats 3 are fixed to one side of the base plate 1 by screws. Two corresponding linear bearing seats 3 form a group. Each group of two linear bearing seats 3 is connected to a main lifting shaft 4 via a linear bearing. A tray is fixed between the upper ends of the two main lifting shafts 4 via a support plate 5. A lifting nut 6 is threadedly connected to the middle of each main lifting shaft 4. A lifting seat 7 is provided between two lifting nuts 6, and the lifting seat 7 is rotatably connected to the lifting nut 6. A sprocket 8 is fixed to the lower side of the two lifting nuts 6. One side of the lifting seat 7 is electrically connected to... A servo motor 9 is mounted on the base 18. A sprocket 17 is fixed to the end of the output shaft of the servo motor 9. The sprocket 17 and two sprockets 8 are connected by a chain drive. A buffer is provided at the lower end of each lifting nut 6. When the cam 2 rotates, it drives the lifting seat 7 to move up and down. The cam 2 is located between the lifting seat 7 and the base plate 1. A sliding groove 10 is provided on one side of the cam 2, and a roller needle bearing 11 is provided on one side of the lifting seat 7. The roller needle bearing 11 is located inside the sliding groove 10, and slides along the sliding groove 10 when the cam 2 rotates. The buffer includes a lifting buffer spring 13. The upper end of the lifting buffer spring 13 is connected to the lower end of the lifting nut 6 through a thrust bearing 12. A positioning sleeve 14 is fixed to the lower end of the buffer spring 13. The positioning sleeve 14 is fixed to the corresponding position of the main lifting shaft 4. The upper and lower sides of the lifting seat 7 are connected to the lifting nut 6 through thrust ball bearings 15, and a composite bearing 16 is set between the lifting seat 7 and the lifting nut 6. Two tensioning sprocket assemblies 19 are fixed on the left and right sides of the motor seat 18. The two tensioning sprocket assemblies 19 tension the chains on both sides of the sprocket 17 respectively. The tensioning sprocket assembly 19 is existing technology. The compression sprocket assembly includes a short shaft. The short shaft is connected to the lifting seat 7 through a bearing seat, and a pressure sprocket is set at one end of the short shaft. The main shaft end of the external drive mechanism is fixedly connected to one side of the cam 2. The cam 2 is driven by the rotation of the external drive mechanism. When the cam 2 rotates, the sliding groove 10 is positioned differently from the rotation center, thus driving the lifting seat 7 to move up and down, thereby moving the pressing table up and down for pressing. When the pressing table needs to be adjusted, the servo motor 9 rotates, which drives the sprocket 17. Through the transmission of sprocket 17, sprocket 8, and chain, the two lifting nuts 6 rotate. When the lifting nuts 6 rotate, the main lifting shaft 4 moves up and down, thereby fine-tuning the position of the pressing table. This servo-controlled automatic lifting mechanism for the pressing table has a simple structure and is easy to operate. It can achieve fully automatic adjustment, making the adjustment faster and more accurate, avoiding the large errors that affect the processing of pages when manually adjusting.

[0017] In use: The main shaft end of the external drive mechanism is fixedly connected to one side of the cam 2. The rotation of the external drive mechanism drives the cam 2 to rotate. When the cam 2 rotates, the sliding groove 10 is at a different position from the rotation center, thereby driving the lifting seat 7 to move up and down, thus moving the support table up and down for support. When the support table needs to be adjusted, the rotation of the servo motor 9 can drive the second sprocket 17. Through the transmission of the second sprocket 17, the first sprocket 8 and the chain, the two lifting nuts 6 can be driven to rotate. When the lifting nuts 6 rotate, the main lifting shaft 4 can move up and down, thereby fine-tuning the up and down position of the support table.
