Description

Technical Field

[0001] This utility model relates to the field of papermaking machine technology, specifically to a multi-axis transmission collaborative control device for papermaking machines. Background Technology

[0002] In the modern papermaking industry, multi-axis drive coordinated control refers to the precise and synchronous coordinated control of multiple drive shafts within a papermaking machine to achieve efficient cooperation among various process stages in paper production. Papermaking is a complex, continuous production process. From raw material transportation and pulp preparation to paper forming, pressing, drying, and subsequent winding, each stage relies on the stable operation and mutual cooperation of drive shafts. Multi-axis drive coordinated control ensures that each drive shaft operates according to predetermined speed, torque, and phase relationships, thereby guaranteeing uniform paper thickness, stable tension, and quality standards. For example, during the pressing and drying stages, drive shafts at different locations need to operate at specific speed ratios to avoid problems such as wrinkles and breakage. As the papermaking industry's requirements for paper quality and production efficiency continue to increase, multi-axis drive coordinated control has become one of the key technologies for achieving high-performance, high-quality papermaking. It not only improves paper production efficiency and reduces scrap rates but also meets the diverse market demands for different specifications and qualities of paper, which is of great significance for enhancing the market competitiveness of papermaking enterprises.

[0003] Traditional multi-axis drive control technology primarily employs individual control of each drive shaft, lacking an effective collaborative control mechanism. This control method has numerous drawbacks, severely impacting the production performance and product quality of papermaking machines. Firstly, individual control struggles to guarantee synchronization and coordination between drive shafts. Because the control of each drive shaft is independent, speed deviations and phase errors easily occur during operation, leading to tension fluctuations in the paper during transport, thus affecting the paper's flatness and thickness uniformity. Secondly, traditional technology has a slow response speed, unable to adapt promptly to dynamic changes in the papermaking process. When papermaking machine operating parameters change, such as paper size adjustments or production speed variations, traditional control systems require a considerable amount of time to adjust the operating status of each drive shaft, easily causing production interruptions and unstable product quality. Furthermore, traditional multi-axis drive control technology has high maintenance costs. Since the control units for each drive shaft operate independently, it increases system complexity and potential failure points. In the event of a fault, maintenance personnel must troubleshoot each control unit individually, consuming significant time and effort, leading to prolonged production downtime and substantial economic losses for the company. These shortcomings severely restrict the development of the papermaking industry, making traditional papermaking machines inadequate in the face of increasingly fierce market competition and ever-improving paper quality requirements. Therefore, developing an efficient and stable multi-axis drive collaborative control device is of significant practical importance. To this end, we propose a multi-axis drive collaborative control device for papermaking machines. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-axis transmission collaborative control device for papermaking machines, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a multi-axis transmission collaborative control device for a papermaking machine, comprising a base plate, a transmission groove on the top of the base plate, a forward and reverse motor fixedly connected to the outer wall of one end of the base plate, the rotating shaft of the forward and reverse motor extending to one end of the inner wall of the transmission groove, a bidirectional threaded roller fixedly connected to the rotating shaft of the forward and reverse motor, the end of the bidirectional threaded roller away from the forward and reverse motor being movably connected to one end of the inner wall of the transmission groove, limit grooves being opened on both sides of the top of the base plate near the transmission groove, limit rods being fixedly connected to both ends of the inner wall of the limit grooves, a movable seat being threadedly connected to the outer wall of one end of the bidirectional threaded roller, and a second movable seat being threadedly connected to the outer wall of the end of the bidirectional threaded roller away from the movable seat, the bottom sides of the movable seat and the second movable seat being movably sleeved on the outer wall of one end of the limit rod.

[0006] Preferably, the top of the movable seat is movably connected to a rotating shaft, and the top of the second movable seat is movably connected to a second rotating shaft.

[0007] Preferably, a turntable is fixedly connected to one side of the rotating shaft, and a second turntable is fixedly connected to one side of the second rotating shaft, with the turntable and the second turntable being parallel to each other on the same side.

[0008] Preferably, the turntable and the outer wall of the second turntable are provided with a plurality of transmission columns that are distributed in a ring at equal intervals.

[0009] Preferably, a worm gear is movably connected to the outer wall of the base plate near the turntable and the second turntable, a fixed frame is fixedly connected to the outer wall of the base plate near the worm gear, a servo motor is fixedly connected to the outer wall of the fixed frame, and the rotating shaft of the servo motor is fixedly connected to the connecting shaft at one end of the worm gear.

[0010] Preferably, the output end of the transmission column is meshed with the worm gear.

[0011] Preferably, the outer walls at both ends of the base plate are provided with two mounting seats that are equidistant from each other in the horizontal direction.

[0012] Compared with the prior art, this utility model provides a multi-axis transmission coordinated control device for a papermaking machine, which has the following beneficial effects:

[0013] 1. This multi-axis drive coordinated control device for papermaking machines, compared to traditional multi-axis drive control technology which uses individual control of each drive shaft, lacks effective coordination between shafts and is prone to speed deviations and phase errors. For example, in the paper pressing stage, inconsistent speeds of drive shafts at different positions can lead to uneven paper tension, wrinkles, or even breakage, severely affecting paper flatness and thickness uniformity. This device, through the cooperation of forward and reverse motors and bidirectional threaded rollers, can flexibly adjust the positions of the moving base and the second moving base, thereby precisely controlling the positions of the turntable and the second turntable. Simultaneously, the meshing transmission of the worm gear and the drive column achieves precise synchronization and coordination between the drive shafts, ensuring stable tension and speed matching at each stage of paper production, effectively avoiding quality problems caused by traditional technology, and significantly improving the overall quality of the paper.

[0014] 2. This multi-axis transmission coordinated control device for the papermaking machine uses the movement of the moving base and the second moving base to drive the movement of the rotating shaft and the second rotating shaft, providing stable support for the transmission components and ensuring smooth transmission. The turntable and the second turntable move in parallel, providing accurate positioning for subsequent transmission coordination, ensuring accurate relative positions of each component, and improving transmission precision. Simultaneously, the equidistantly distributed transmission columns on one side of the outer wall of the turntable and the second turntable increase the contact area and transmission points with subsequent transmission structures, making the transmission more uniform and stable, effectively reducing energy loss and improving transmission efficiency. Furthermore, the meshing connection allows the rotation of the worm gear to accurately drive the rotation of the transmission columns, achieving precise power transmission and ensuring that the turntable and the second turntable rotate at the set speed and direction, ensuring the coordination and stability of the multi-axis transmission.

[0015] 3. This multi-axis drive coordinated control device for the paper machine drives the bidirectional threaded roller to rotate via forward and reverse motors. Under the limiting action of the limiting groove and the limiting rod, the moving seat and the second moving seat move synchronously in opposite directions on the bidirectional threaded roller. This design allows the rotating shaft, the second rotating shaft, the turntable, and the second turntable to flexibly and precisely change positions according to the needs of the paper machine, greatly enhancing the device's adaptability to different production scenarios and process requirements, and meeting the transmission needs of the paper machine at different production stages and product specifications.

[0022] Furthermore, a rotating shaft 9 is movably connected to the top of the movable seat 7, and a second rotating shaft 10 is movably connected to the top of the second movable seat 8.

[0024] Furthermore, the outer wall of one side of the turntable 11 and the second turntable 12 is provided with a number of transmission columns 13 that are distributed in a ring at equal intervals. The ring at equal intervals of the transmission columns 13 increases the contact area and transmission points with the subsequent transmission structure, making the transmission more uniform and stable, effectively transmitting power, reducing energy loss in the transmission process, and improving transmission efficiency.

[0025] Furthermore, a worm gear 14 is movably connected to the outer wall of the base plate 1 near the turntable 11 and the second turntable 12. A fixing frame 15 is fixedly connected to the outer wall of the base plate 1 near the worm gear 14. A servo motor 16 is fixedly connected to the outer wall of the fixing frame 15.

[0046] Working principle: First, the forward and reverse motor 3, in conjunction with the bidirectional threaded roller 4, achieves synchronous reverse movement of the movable seat 7 and the second movable seat 8. A transmission groove 2 is formed at the top of the base plate 1. The forward and reverse motor 3 is fixed to the outer wall of one end of the base plate 1, and its rotating shaft extends to one end of the inner wall of the transmission groove 2 and is fixedly connected to the bidirectional threaded roller 4. The other end of the bidirectional threaded roller 4 is movably connected to the other end of the inner wall of the transmission groove 2. When the forward and reverse motor 3 starts, it drives the bidirectional threaded roller 4 to rotate. Because the threads at both ends of the bidirectional threaded roller 4 are in opposite directions, the movable seat 7 and the second movable seat 8, threadedly connected to it, move synchronously in opposite directions under the guidance of the limiting rod 6 within the limiting groove 5. Then, the positioning effect of the transmission components is achieved through the linkage of the movable seat 7 and the second movable seat 8 with the rotating shaft 9 and the second rotating shaft 10. The top of the movable seat 7 is movably connected to the rotating shaft 9, and the top of the second movable seat 8 is movably connected to the second rotating shaft 10. As the movable seat 7 and the second movable seat 8 move, the rotating shaft 9 and the second rotating shaft 10 also move accordingly. One side of the rotating shaft 9 is fixedly connected to the turntable 11, and one side of the second rotating shaft 10 is fixedly connected to the second turntable 12. The turntables 11 and 12 are parallel on the same side, thus completing the positioning of the transmission components. The rotation of the transmission column 13 is achieved by the servo motor 16 driving the worm gear 14. The worm gear 14 is movably connected to the outer wall of the base plate 1 near the turntables 11 and 12. A fixing frame 15 is fixedly connected to the outer wall of the base plate 1 near the worm gear 14. The servo motor 16 is fixedly connected to the outer wall of the fixing frame 15, and the rotating shaft of the servo motor 16 is fixedly connected to the connecting shaft at one end of the worm gear 14. When the servo motor 16 starts, it drives the worm gear 14 to rotate. Several transmission columns 13 are arranged in a ring at equal intervals on one side of the outer wall of turntable 11 and second turntable 12. The output end of the transmission column 13 is meshed with the worm gear 14. When the worm gear 14 rotates, it drives the transmission column 13 to rotate, which in turn drives turntable 11 and second turntable 12 to rotate. Through the rotation of turntable 11 and second turntable 12, the related components of the papermaking machine are linked to achieve a multi-axis transmission coordinated control effect. The rotation of turntable 11 and second turntable 12 provides power input to the papermaking machine. Through reasonable transmission design, coordinated control of multiple axes of the papermaking machine is achieved, meeting the process requirements of papermaking production. Two mounting seats 17 are arranged laterally at equal intervals on the outer walls of both ends of the base plate 1. These can be used to install the entire device in a suitable position on the papermaking machine to ensure stable operation of the device.
