[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] according to Figure 1-3 This utility model provides a paper feeding mechanism with adjustable operating width, including: a conveyor belt 1, a paper pressing structure 2, a paper suction device 3, a paper delivery table 4, and a lifting structure 5.

[0020] The conveyor belt 1 is located on one side of the paper delivery table 4. The paper suction device 3 is located on the other side of the paper delivery table 4. The paper pressing structure 2 is located on the side of the conveyor belt 1 away from the ground. The paper pressing structure 2 includes: paper pressing rollers 21 and paper pressing belts 22. The paper pressing rollers 21 are located at both ends of the conveyor belt 1. The paper pressing belts 22 are fitted onto the paper pressing rollers 21 at both ends of the conveyor belt 1. The paper pressing rollers 21 are movable relative to the conveyor belt 1.

[0021] When paper feeding is required, the suction device 3 picks up the material and places it on the paper delivery table 4. The material then moves with the paper delivery table 4 to the conveyor belt 1. At the conveyor belt 1, the material is simultaneously pressed down by the conveyor belt 1 and the pressure belt 22, making it difficult to move. By activating the conveyor belt 1 and the pressure roller 21, the material is transported between the pressure belt 22 and the conveyor belt 1, and comes into contact with both. This creates friction between the material and the aforementioned structures, preventing the material from shifting and allowing for the transport of materials of various specifications within a certain range. Furthermore, if the material specifications differ significantly, when transporting smaller materials, the distance between the two pressure belts 22 may be too great, making it difficult to match the material, or the distance may be too small, resulting in a concentrated force distribution on the material and causing paper deformation. The pressure roller 21 of this invention can move relative to the conveyor belt 1, changing the distance between the two pressure rollers 21 and thus the distance between the pressure belts 22, to accommodate materials of various specifications. This invention applies force to the material through the pressure belt 22, making it difficult for the material to shift to the side. It also has a movable pressure roller 21 to match materials of various specifications, which allows the invention to adjust the running width according to the material, making it more convenient to use.

[0022] The conveyor belt 1 has side plates 11 on both sides. The paper pressing structure 2 also includes: a positioning rod 23 and a connecting block 24. The positioning rod 23 rotatably passes through the side plate 11. The positioning rod 23 passes through the connecting block 24. The positioning rod 23 is threaded. The connecting block 24 has a threaded groove corresponding to the thread. The conveyor belt 1 also includes: a limiting rod 12. The limiting rod 12 is connected to the side plate 11. The limiting rod 12 has a groove on the side near the connecting block 24. The connecting block 24 has a protrusion 241 corresponding to the groove. The protrusion 241 extends into the groove. The protrusion 241 can slide within the groove.

[0023] Because the connecting block 24 has a protrusion 241 corresponding to the groove of the limiting rod 12, the connecting block 24 cannot rotate. When it is necessary to change the distance between the two paper pressing rollers 21, the positioning rod 23 is rotated. Since the connecting block 24 cannot rotate, and the connecting block 24 and the positioning rod 23 are respectively provided with corresponding screw grooves and threads, the connecting block 24 will move on the limiting rod 12 when the positioning rod 23 rotates. By setting the corresponding threads and screw grooves, the connecting blocks 24 on both sides can move closer or further apart when the positioning rod 23 rotates, thereby changing the distance between the connecting blocks 24 to suit materials of different specifications.

[0024] The lifting structure 5 includes: a support platform 51, a base 52, and a telescopic structure 53. The paper suction device 3 is located on one side of the support platform 51, and the base 52 is located on the other side of the support platform 51. The telescopic structure 53 is located on the side of the base 52 closest to the support platform 51. The telescopic structure 53 includes: a support rod 531, a spring 532, a support cylinder 533, and a support plate 534. The support plate 534 is located inside the support cylinder 533. The support rod 531 extends into the support cylinder 533. One end of the spring 532 is connected to the support rod 531, and the other end is connected to the support plate 534. The telescopic structure 53 also includes: a connecting rope 535 and a rotating rod 536. The support plate 534 has a through hole 5341. The connecting rope 535 passes through the through hole 5341. One end of the connecting rope 535 is connected to the support rod 531, and the other end is connected to the rotating rod 536. The rotating rod 536 can rotate relative to the support rod 531. The base 52 has a threaded opening 521. A rotating rod 536 extends into the threaded opening 521. A threaded ridge is provided on one side of the rotating rod 536. The threaded opening 521 corresponds to the threaded ridge. There are several lifting structures 5. Some of the support rods 531 of the lifting structures 5 are fixed to the support platform 51, while other support rods 531 are not fixed to the support platform 51.

[0025] When paper is sucked up by the suction device 3, the quantity of paper decreases as more paper is sucked up, causing the height of the paper to be sucked up to gradually decrease. This invention features a lifting structure 5. When material is placed on the support platform 51, the support platform 51 presses down on the support rod 531 of the telescopic structure 53, causing the support rod 531 to press against the spring 532. This allows the support rod 531 to gradually extend into the support cylinder 533 and stop at a certain distance. As material is continuously sucked up, the overall height of the material decreases, and the overall weight also changes, causing the spring 532 to rebound, allowing the material to automatically rise and fall to match the height of the suction device 3. This avoids poor suction due to the material being too high or too low. For materials of different specifications, their weights also vary. The telescopic structure 53 of this invention, which is not fixed to the support platform 51, is also equipped with a connecting rope 535 and a rotating rod 536. When the rotating rod 536 is rotated in a certain direction, the connecting rope 535 continuously wraps around the rotating rod 536, causing the support rod 531 to move away from the support platform 51. This reduces the amount of telescopic structure 53 supporting the support platform 51, changing the position of the support platform 51 under a certain weight, thus adapting to materials of different specifications. This allows the height to be automatically adjusted according to different material specifications, enabling the paper suction device 3 to pick up materials at the appropriate position, resulting in a more stable suction process.

[0026] Working principle and usage process of this utility model:

[0027] When materials need to be conveyed, the paper pressing structure 2 is adjusted according to the specifications of the materials. The positioning rod 23 is rotated so that the connecting blocks 24 on both sides move closer or further apart along the positioning rod 23. The protrusion 241 slides in the groove of the limiting rod 12 and stops when the connecting block 24 moves to a certain position. Then, the materials are placed on the support platform 51 so that the support rod 531 presses the spring 532, causing the support platform 51 to move closer to the base 52. Then, a certain number of rotating rods 536 are rotated according to the specifications of the materials so that the connecting rope 535 is wound around the rotating rods 536, so that the connecting rope 535 moves away from the support platform 51, thereby driving the support rod 531 away from the support platform 51, changing the position of the support platform 51, and moving the materials to a suitable position. Then, the paper suction device 3 and the paper pressing wheel 21 are activated so that the paper suction device 3 picks up the paper and feeds it onto the paper delivery platform 4, then to the conveyor belt 1, and then to the paper pressing belt 22. The paper is then conveyed by the conveyor belt 1 and the paper pressing belt 22.

[0028] In summary, this invention applies force to the material through a paper-pressing belt, making it difficult for the material to shift to the side. It also features movable paper-pressing wheels to match materials of various specifications, allowing the invention to adjust its operating width according to the material, making it convenient to use.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
