[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0025] See also Figures 1 to 6 As shown, a structurally improved riveting tube binding machine of the utility model includes a frame 1 for carrying external pieces to be bound, a punching mechanism 7 movably mounted on the frame 1 to perform a punching operation on the pieces to be bound, the punching mechanism 7 includes a bracket 8 arranged away from the frame 1 for fixing a hollow drill, a hollow drill 5 arranged on the bracket 8, and a first driving member 9 for driving the bracket 8 to reciprocate so that the hollow drill 5 punches holes in the external pieces to be bound to realize the punching operation.

[0026] It also includes a riveting mechanism 6 used in conjunction with the punching mechanism 7. A first gear bar group 11 is provided at one end of the punching mechanism 7 close to the riveting mechanism 6. The first driving member 9 is used to realize the lifting and lowering of the punching mechanism 7 and the riveting mechanism 6, thereby ensuring the continuity and accuracy of the punching and riveting operations. The two steps of punching and riveting can be carried out simultaneously, reducing the waiting time of the equipment and thus improving the binding efficiency.

[0027] Specifically, the punching mechanism 7 is provided with a first gear set 13 that cooperates with the first driving member 9 to lift the bracket 8 up and down reciprocatingly. After the first gear set 13 receives the rotational force transmitted by the first driving member 9, the first gear set 13 converts the rotational motion into linear motion through the cooperation of its internal gears, thereby driving the bracket 8 to lift up and down reciprocatingly. The first gear set 13 makes the lifting and lowering motion of the punching mechanism 7 more precise and stable, which helps to improve the accuracy and efficiency of punching.

[0028] Specifically, the first gear set 13 includes a threaded rod 12 and a first gear screwed on the threaded rod 12. The threaded rod 12 is fixed on the frame 1. The first gear is rotatably arranged on the bracket 8 so that when the first driving member 9 drives the threaded rod 12 to rotate, the bracket 8 can be driven to move up and down more stably.

[0029] Specifically, the hollow drill 5 is rotatably arranged on the bracket 8, and a second gear meshingly connected with the first gear is arranged on the hollow drill 5. The second gear is used to drive the hollow drill 5 to rotate when the first gear rotates. The spiral matching relationship between the first gear and the threaded rod 12 causes the rotation of the first gear to also cause the bracket 8 to move up and down along the threaded rod 12. In this way, the hollow drill 5 can not only rotate to cut, but also move up and down to adjust the cutting depth or position.

[0030] Specifically, the riveting mechanism 6 includes a riveting tube 28, on which a rivet head 3 is arranged, and a limit valve 16 is arranged at the lower part of the riveting mechanism 6. The end of the rivet head 3 away from the rivet head 3 is used to limit the rivet head 3 to prevent the rivet head 3 from being damaged due to excessive movement during the riveting process. A positioning sleeve 17 is arranged at the working end of the rivet head 3. The positioning sleeve 17 is slidably arranged on the frame 1 in the up-down direction to support / limit the rivet head 3, so as to ensure the stability and accuracy of the rivet head 3 during the riveting process and improve the riveting quality.

[0031] Specifically, a collecting box 10 used in conjunction with the punching mechanism 7 is arranged on the frame 1 and is arranged on the bracket 8. A chip discharge port 22 connected to the collecting box 10 is provided on the hollow drill 5. Paper scraps generated by punching holes with the hollow drill 5 flow into the collecting box 10 through the chip discharge port 22 to prevent internal accumulation of paper scraps from damaging the hollow drill 5. The chips enter the collecting box 10 and flow out through a cooperative hose to collect the debris.

[0032] Specifically, a carrying plate 15 is provided on the frame 1 for carrying the items to be ordered, and the punching mechanism 7 also includes a paper pressing plate 4 that cooperates with the carrying plate 15 to press the items to be ordered on the carrying plate 15. The paper pressing plate 4 can stably press the items to be ordered on the carrying plate 15 during the punching process to prevent them from moving or tilting, ensure that the hollow drill 5 can be accurately punched at the predetermined position, and improve the accuracy and consistency of the punching.

[0033] Specifically, the frame 1 is also provided with an operating button 19. The operating button 19 is used to control the operating state of the first driving member 9. When the first driving member 9 is in operation, it cooperates with the threaded rod 12 to drive the hollow drill 5 to rotate and lift. The first gear set 13 cooperates with the lifting rod 14 to lift the riveting mechanism 6. When the hollow drill 5 and the riveting mechanism 6 reach the predetermined position, the punching and riveting operations are started. After the punching and riveting operations are completed, the first driving member 9 rotates in the opposite direction to reset the punching mechanism 7 and the riveting mechanism 6 to the initial position, waiting for the next operation.

[0034] Specifically, the first gear bar group 11 is provided with a third gear and a second gear bar 26. When the punching mechanism 7 is raised or lowered, the second gear bar 26 is driven. The second gear bar 26 is used to drive the third gear to rotate. The rotation of the third gear is used to limit the lifting and lowering of the punching mechanism 7 to avoid excessive lifting and lowering to damage the machine and increase the safety of the machine.

[0035] Specifically, the first gear bar set 11 is provided with a first gear bar 25 which is rotated by a third gear to make the riveting mechanism 6 move back and forth, utilizing the principle of mechanical transmission, thereby improving the efficiency and stability of the entire system.

[0036] Specifically, the lower end of the rack 1 is provided with an end foot 27 used in conjunction with the supporting plate 15 to support the rack 1. The end foot 27 serves as a connection point between the rack 1 and the ground or a supporting surface, and can effectively support the rack 1 and objects on it to ensure the stability of the entire system.

[0037] Specifically, the hollow drill 5 has a drill head 24 and a shank 23. The drill head 24 is used for drilling holes in the workpiece to be bound. The diameter of the shank 23 is larger than the diameter of the drill head 24. A chip removal port 22 is provided on the shank 23. A protective cover 21 is provided on the outer cover of the shank 23. The chip removal port 22 is connected to the inner cavity of the protective cover 21 to protect the hollow drill 5 from damage to the drill and increase the life of the hollow drill.

[0038] Specifically, a storage box is also provided on the frame 1, and the storage box is used to store binding machine parts and binding machine cleaning tools.

[0039] Specifically, in other embodiments, a lift for lifting the binding machine is also installed at the bottom of the frame 1. The bottom of the lift has anti-slip textures. The lift realizes the lifting of the binding machine through its internal driving parts. The lifting can adjust the height of the binding machine operating platform to meet the needs of staff of different heights for better operation, and the lowering can make the binding machine compact and not take up space.

[0040] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
