[0019] The usage process of this utility model: In this embodiment, there are two servo motors 200, which drive the first rocker arm 500 and the second rocker arm 600 respectively through a reducer. This dual-servo driven rocker linkage mechanism design has significant advantages in structural simplification and optimization compared with the traditional single-drive method, reducing the number of parts and lowering manufacturing and maintenance costs. During the rotation of the first rocker arm 500, it drives the first connecting rod 700, which in turn drives the pushing module 100 to move. This linkage mechanism design makes the pushing motion more stable and controllable, reduces mechanical impact, and extends the service life of the equipment. At the same time, the second rocker arm 600 drives the limiting plate 900, which in turn drives the first connecting rod 700 and the second connecting rod 800 at the upper and lower ends. In this embodiment, the first connecting rod 700 is symmetrically arranged and connected to the first rocker arm 500 and the second rocker arm 600 respectively. This symmetrical design ensures a balanced distribution of forces, reduces the off-center load phenomenon in the movement of the mechanism, and improves the overall stability and reliability of operation. The second rocker arm 600 is limited by the second connecting rod 800, and the second rocker arm 600 drives the pushing module 100 to move via the first connecting rod 700. The principle is that two sets of servo motors drive the two rockers to swing at different angles, thus achieving the following movement of the pushing plate component. The two connecting rods mentioned above work together to keep the pushing module 100 parallel to the fixed base plate 400, ensuring that the pushing angle of the pushing plate is always perpendicular to the material during the following movement. This constant pushing angle design ensures the stability of the pushing process, significantly improves the pushing quality, and solves the tilting and instability problems that are prone to occur in traditional pushing devices during the pushing process. It is particularly suitable for scenarios with high pushing accuracy requirements. Using dual servo motors to drive the two rockers to swing at different angles, and then using the two rockers to drive the two first connecting rods 700, achieves the following movement of the pushing plate component and the pushing motion of the pushing rod. This dual-servo collaborative control method, compared to the traditional single-motor drive, has higher precision and flexibility, can achieve more complex motion trajectories, and meets the pushing requirements of different materials. In this process, the pushing module 100 is moved in a telescopic manner within a small range by a robotic arm composed of two rockers and connecting rods. From a top-down perspective, the motion trajectory is as follows: when the material is in the latter half of the pushing mechanism, the pushing module 100 is pushed forward to complete the pushing operation, and then retracts to return to its original position. The material in the first half then moves to the second half, and after this movement, the entire device returns to its original position, repeating the action. This efficient motion trajectory design enables rapid return to its original position after pushing, reducing waiting time and improving production efficiency. It is one of the innovative points of the motion mechanism of this utility model and better meets the actual needs of material packaging. At the same time, this motion method also reduces wear and tear on the mechanism and extends the service life of the equipment.

[0020] On the other hand, this invention can drive the active synchronous pulley 150 via the pusher servo motor 140. The active synchronous pulley 150 drives the driven synchronous pulley 120 via the synchronous belt 110. The driven synchronous pulley 120 drives the lead screw nut 1200 to rotate on the fixed side 130 and the supporting side 190 of the lead screw seat. This innovative adjustment mechanism uses a combination of a servo motor-driven synchronous belt and a ball screw, achieving high-precision and repeatable adjustment of the push rod length. This solves the technical problem of traditional pusher devices requiring frequent adjustments or replacements of components when dealing with materials of different specifications, improving the versatility and adaptability of the equipment. The application of the synchronous belt drive system reduces the backlash and noise of gear transmission, improving transmission efficiency and smoothness. In this process, the ball screw 1100 drives the lead screw nut 1200 and the nut connecting plate 1140 to carry the push rod 1150, which, in conjunction with the slider 1160 fixed on it, moves the slider 1160 on the guide rail 1180, thereby achieving the adjustment of the push rod length. This precisely adjustable push-in distance design meets the push-in requirements of materials of different specifications and is a key technological innovation of this invention. By precisely controlling the push-in depth, the quality of material feeding is further improved. The cooperation between the ball screw and the guide rail ensures high precision and low friction in the push rod movement, reduces energy loss, and improves the adjustment response speed. In this process, the sensing screw 1110 serves as a fixed mechanical reference point for the starting or zero position of the push rod length adjustment. This mechanical reference point design provides a reliable position benchmark for the system, avoiding potential position drift problems after long-term operation and enhancing the stability and reliability of the system. Stroke calibration: When adjusting the push rod length, the sensing screw 1110 can serve as a calibration point, ensuring that each adjustment is based on the proximity switch 1130 returning to zero, improving the consistency and accuracy of adjustment. This automatic calibration function greatly simplifies the operation process, reduces human error, and improves production efficiency and product quality consistency. Position coding: The sensing screw and proximity switch 1130 work together to form a simple position coding system to indicate different preset push rod length positions. This innovative control method employs a position coding system combining a sensing screw and a proximity switch to achieve real-time monitoring and precise control of the push rod position. This improves the system's intelligence and ease of operation, and is the core technology of this invention's intelligent position control. This coding system is simple, reliable, and resistant to environmental interference, making it suitable for stable operation in various industrial environments. During push rod length adjustment, the sensing screw reciprocates between two proximity switch positions, preventing the lead screw nut from exceeding its travel and colliding with the lead screw seat fixed side 130 and the lead screw seat support side 190. This travel protection design effectively prevents collision damage to mechanical components, improves equipment safety and reliability, reduces maintenance downtime, and lowers maintenance costs.The proximity switch 1130 detects the position of the nut connecting plate 1140 and feeds back the current push rod position status to the control system. Based on set parameters, the control system drives the motor to move the lead screw nut with the proximity switch 1130 as the origin. This closed-loop control system ensures the accuracy and repeatability of the push rod position, maintaining high precision even after long-term operation, meeting the requirements for high-quality material feeding. This adjustment can be made during use by activating the servo motor as needed, or preset during shutdown based on the material position of the next batch. This flexible adjustment method greatly improves the adaptability and production efficiency of the equipment, allowing operators to quickly adjust equipment parameters according to production needs, reducing changeover time and increasing equipment utilization. Compared with existing technologies, this invention achieves several beneficial effects through the above design: simplified and optimized structure, precisely adjustable pushing distance, constant pushing angle, intelligent position control, and efficient motion trajectory. It is particularly suitable for high-precision packaging production lines requiring precise control of pushing depth, providing more reliable technical support for the feeding of precision materials. At the same time, the modular design of this invention facilitates maintenance and upgrades, further improving the practicality and economic benefits of the equipment.

[0021] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
