However, currently, most waste cleaning machines use manual methods for paper feeding during use, which is not only time-consuming and laborious, but also increases the labor intensity of workers, and the overall practicality is poor.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A manual auxiliary paper feeding mechanism includes a frame body. A conveying roller is arranged inside one end of the frame body. A motor is fixedly installed at the top end of the other side of the frame body, and the output end of the motor is connected to a threaded rod. A threaded sleeve is sleeved on the outer surface of the threaded rod, and a lifting frame is fixedly installed at one end of the threaded sleeve. A guiding block is fixedly installed on the side wall of the lifting frame, and a guiding rod penetrates through the inside of the guiding block. A limiting structure is arranged on the side wall of the lifting frame.

[0006] As a preferred technical solution of the utility model, the limiting structure includes a damper, a limiting plate, a protective pad, and a spring. The damper is fixedly installed on the side wall of the lifting frame, and one end of the damper is fixedly connected to the limiting plate.

[0007] As a preferred technical solution of the present utility model, a cylinder is distributed on one side of the motor, and a push plate is fixedly connected to the other end of the cylinder.

[0008] As a preferred technical solution of the present utility model, the conveying rollers are equidistantly distributed on one side of the bottom of the frame body, and a rotational connection is formed between the conveying rollers and the frame body.

[0009] As a preferred technical solution of the present utility model, the threaded rod is threadedly connected to the threaded sleeve through a thread groove, and the threaded rod penetrates through the inner side of the threaded sleeve and is vertically connected to the side wall of the frame body.

[0010] As a preferred technical solution of the present utility model, the lifting frame is slidably connected to the guide rod through the guide block, and the guide blocks are symmetrically distributed along the vertical center line of the lifting frame.

[0011] Compared with the prior art, the beneficial effects that the present utility model can achieve are:

[0012] 1. By combining the provided motor, threaded rod, threaded sleeve and lifting frame, the purpose of assisting in paper feeding can be conveniently achieved subsequently, which has higher practicability and efficiency compared with the existing manual paper feeding method. When the motor works, the threaded rod will rotate accordingly, and then the rotation of the threaded rod realizes the longitudinal movement of the threaded sleeve, and further realizes the longitudinal lifting of the lifting frame, so as to facilitate the subsequent auxiliary paper feeding process;

[0013] 2. By using the provided damper, spring and limit plate, the paper material during the lifting process can be limited and protected to prevent it from shaking greatly during the lifting process, resulting in the subsequent material falling over. When the limit plate moves horizontally, it will push the damper, and at the same time the spring will also deform to generate a reverse force. Combining the reverse forces generated by the deformations of the two can achieve the purpose of protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0020] Embodiment

[0021] Please refer to Figure 1 As shown, the present utility model provides an artificial auxiliary paper loading mechanism, including a frame body 1. A conveyor roller 2 is arranged inside one end of the frame body 1. The conveyor rollers 2 are equidistantly distributed on one side of the bottom of the frame body 1, and the conveyor rollers 2 are rotatably connected to the frame body 1. A motor 3 is fixedly installed at the top of the other side of the frame body 1, and the output end of the motor 3 is connected to a threaded rod 4. A threaded sleeve 5 is sleeved on the outer surface of the threaded rod 4, and a lifting frame 6 is fixedly installed at one end of the threaded sleeve 5. A guide block 7 is fixedly installed on the side wall of the lifting frame 6, and a guide rod 8 penetrates through the inside of the guide block 7. A limiting structure is arranged on the side wall of the lifting frame 6;

[0022] During use, the paper material to be loaded is placed on the surface of the conveyor roller 2, and then the paper material is conveyed to the inside of the lifting frame 6 by the conveyor roller 2, and then the lifting process is carried out;

[0023] As a further implementation manner of this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a motor 3 is fixedly installed at the top end of the other side of the frame body 1, and the output end of the motor 3 is connected with a threaded rod 4. The threaded rod 4 is threadedly connected with a threaded sleeve 5 through a thread groove, and the threaded rod 4 penetrates through the inner side of the threaded sleeve 5 and is vertically connected to the side wall of the frame body 1. A threaded sleeve 5 is sleeved on the outer surface of the threaded rod 4, and a lifting frame 6 is fixedly installed at one end of the threaded sleeve 5. The lifting frame 6 is slidably connected with a guide rod 8 through a guide block 7, and the guide blocks 7 are symmetrically distributed along the vertical center line of the lifting frame 6. A guide block 7 is fixedly installed on the side wall of the lifting frame 6, and a guide rod 8 penetrates through the inner side of the guide block 7. A damper 9 is fixedly installed on the side wall of the lifting frame 6, and one end of the damper 9 is fixedly connected with a limiting plate 10. A protective pad 11 is arranged on the side wall of the limiting plate 10. A spring 12 is distributed on one side of the damper 9. The damper 9, the limiting plate 10, the protective pad 11 and the spring 12 form a limiting structure, and the limiting structure is arranged on the side wall of the lifting frame 6. A cylinder 13 is distributed on one side of the motor 3, and the other end of the cylinder 13 is fixedly connected with a push plate 14;

[0024] When the paper material is placed on the surface of the conveying roller 2, the lifting frame 6 will be located inside the bottom of the frame body 1. Then, the paper material is conveyed to the inside of the lifting frame 6 by the rotation of the conveying roller 2. Then, when the paper material is conveyed to the inside of the lifting frame 6, it will horizontally push the symmetrically arranged limiting plates 10 on both sides. Then, the limiting plates 10 move horizontally to push the spring 12, and at the same time, the damper 9 will also deform with the movement of the limiting plates 10. Then, by combining the reverse acting forces generated by the deformation of the spring 12 and the damper 9, the horizontal reset of the limiting plates 10 can be realized. Thus, the paper material can be limited and clamped by the limiting plates 10 to ensure its stability during the subsequent longitudinal lifting process. The setting of the protective pad 11 can further serve the purpose of protection. Then, the motor 3 works to drive the threaded rod 4 to rotate accordingly, and the longitudinal movement of the threaded sleeve 5 is realized by the rotation of the threaded rod 4, so as to realize the longitudinal lifting of the lifting frame 6, which is convenient for subsequent auxiliary paper feeding treatment. When the lifting frame 6 moves to the specified position height, the cylinder 13 works to push the push plate 14, and then the paper material is pushed out of the inside of the lifting frame 6 by the movement of the push plate 14. The whole structure is convenient and fast, and has higher practicability.
