Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] This embodiment provides a paper roll feeding device, such as... Figure 1 The system includes a workbench 1, two drive mechanisms 2, and two traction devices 3. The workbench 1 has a positioning groove 101 on its exterior for positioning the central shaft of the paper roll. The drive mechanisms 2 are symmetrically installed on the upper end of the workbench 1, and their output shafts are connected to the corresponding traction devices 3. The lower part of the traction device 3 is rotatably connected to the workbench 1 through a hinge structure, and its top end is provided with a barb part 301 for supporting the central shaft of the paper roll. When both ends of the central shaft of the paper roll are placed on the barb parts 301 at the top of the two traction devices 3, the drive mechanism 2 is activated, driving the traction device 3 to rotate upward around the hinge point, causing the central shaft of the paper roll to move upward synchronously and slide into the positioning groove 101 on the outside of the workbench, thereby realizing the automatic feeding and positioning of the paper roll.

[0016] In the initial state, the traction device 3 is in a low position, with its top hook 301 located below the positioning groove 101 of the worktable 1. The central shafts at both ends of the paper roll to be loaded are placed on the hooks 301 at the top of the two traction devices 3, respectively, to complete the initial support. Subsequently, the two drive mechanisms 2 symmetrically installed on the upper part of the worktable 1 are activated. The output shafts of the drive mechanisms 2 drive the traction device 3 to rotate upward around the hinge point between its lower part and the worktable 1. During the rotation, the traction device 3 lifts the central shaft of the paper roll synchronously upward through the hooks 301. When it reaches the highest position, the central shaft of the paper roll slides along the hooks 301 into the pre-set positioning groove 101 on the outer side of the worktable 1. After the traction device 3 continues to rotate or returns to its original position, it disengages from the supported state, and the central shaft of the paper roll is stably positioned in the positioning groove 101, completing the automatic loading and positioning process. This process achieves smooth lifting and precise placement of the paper roll through mechanical linkage, without manual intervention, improving loading efficiency and operational safety.

[0017] Furthermore, the workbench 1 includes two symmetrically arranged right-angled trapezoidal baffles and a sliding assembly; several connecting rods are provided between the lower ends of the two right-angled trapezoidal baffles, and sleeves are fitted around the outer periphery of the connecting rods, with the sleeves and connecting rods forming the sliding assembly. The right-angled trapezoidal baffles not only have good mechanical load-bearing performance, enhancing the rigidity and deformation resistance of the overall structure, but also provide a reliable installation foundation for positioning the central shaft of the paper roll; the several connecting rods provided between the lower ends of the two baffles and the sleeves fitted around their outer periphery form a sliding fit structure, constituting the sliding assembly, allowing the sleeves to slide along the axial direction of the connecting rods, facilitating material conveying by the device and achieving smooth docking with downstream equipment.

[0018] Furthermore, several crossbeams connect the right-angled sides of the two right-angled trapezoidal baffles, and the drive mechanism 2 is fixedly installed at both ends of the crossbeams. This structure rigidly connects the two right-angled trapezoidal baffles through the crossbeams, significantly enhancing the overall structural strength and stability of the workbench and effectively preventing structural deformation or vibration during the operation of the drive mechanism 2 or the lifting of the paper roll. At the same time, the crossbeams serve as the mounting base for the drive mechanism 2, providing a high-rigidity and high-precision mounting reference surface, ensuring that the drive mechanisms 2 on both sides are arranged symmetrically and coaxially, thereby ensuring the synchronous movement of the traction devices 3 on both sides, improving the coordination of actions and the reliability of feeding.

[0019] Furthermore, the two right-angled trapezoidal baffles are provided with positioning grooves 101 on their hypotenuses. The arrangement of the positioning grooves 101 on the hypotenuses facilitates processing and forming, has a simple structure, provides stable positioning, effectively prevents the paper roll from axially shifting or deviating during subsequent operation, ensures coaxiality and smooth operation after clamping, and further improves the automation level and operational accuracy of the equipment.

[0020] Furthermore, the traction device 3 has a triangular structure. One vertex of the triangle is connected to the output shaft of the drive mechanism 2, another vertex is hinged to a connecting rod located below it via a pivot 302, and the third vertex is provided with the hook portion 301. This triangular structure has good mechanical stability and motion determinism. The three vertices respectively undertake the functions of drive input, rotational support, and load bearing. The force path is clear, which can effectively transmit the driving force and bear the weight of the paper roll, avoiding structural deformation or motion instability. The drive mechanism 2 directly drives one vertex of the triangular structure through the output shaft, causing the entire traction device 3 to rotate smoothly around the hinge point, realizing the arc lifting action of the hook portion 301. The motion trajectory is controllable and the action is reliable. At the same time, the hook portion 301 is located at the third vertex, at the top of the structure. During the lifting process, it can maximize the height of the paper roll's central axis, ensuring that it slides smoothly into the positioning groove 101 on the inclined side of the baffle, completing precise positioning.

[0021] Furthermore, the hook portion 301 is an outwardly curved hook. This structural design effectively limits the paper roll center axis during the lifting process, preventing it from accidentally coming off during the upward movement, thus improving the safety and reliability of the feeding process. In addition, this hook structure facilitates the paper roll center axis to slide into the support position from the outside, which is conducive to the quick clamping of manual or mechanical winding, further improving the ease of operation and the efficiency of automated equipment operation.

[0022] Furthermore, the drive mechanism 2 is a servo motor. Using a servo motor as the drive mechanism 2 enables precise control of the movement of the traction device 3. The servo motor possesses high responsiveness and high repeatability, ensuring synchronous start-up and operation of the drive mechanisms 2 on both sides. This avoids paper roll tilting or uneven loading caused by asynchronous movements, significantly improving the reliability and safety of the feeding process.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
