DETAILED DESCRIPTION

[0030] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0032] like Figures 1 to 8As shown, a paper pushing structure of a binding machine is disclosed, including a workbench 1 and a table top 2, the table top 2 is used to support the materials to be bound, a push paper board 3 is provided on the opposite side of the table top 2, and a spacer 5 is provided on the push paper board 3 at the position of the working hole 4 of the table top 2 to avoid the working hole 4, and the push paper board 3 is connected to an electric pushing mechanism, which drives the push paper board 3 forward / backward to position the materials to be bound.

[0033] In some embodiments, as Figure 7 As shown, the table 2 is provided with a press board 19 that is electrically raised and lowered. This is conducive to the motorized automatic positioning and automatic pressing in conjunction with the push board 3 of the present disclosure. The working principle can be referred to as follows. First, the user places the binding material on the table 2. When placing it, the binding material is pushed toward the side of the push board 3 into the workbench 1, and the binding material is pressed against the push board 3, and the push board 3 is used to position it (i.e., to position it). In this way, the push board 3 provides a reference position by moving forward / backward. When the binding material is pressed against the push board 3, the positioning is completed, thereby obtaining the required position. Then, the press board 19 is lowered to press the binding material, thereby completing the motorized adjustment and fixation of the binding material, which is conducive to automation.

[0034] Another positioning method is to first make the bound material lean against the push paper board 3, and the push paper board 3 performs initial positioning, and then according to the required binding position, that is, the distance between the working hole 4 and the side surface of the bound material leaning against the push paper board 3, the push paper board 3 moves forward to push the bound material, thereby obtaining the required aforementioned distance (that is, positioning), and then the pressing paper 19 is lowered to press the bound material, thereby completing the electric adjustment and fixation of the bound material, which is conducive to automation.

[0035] In some embodiments, as Figure 7 As shown, support posts 20 are provided at each end of the paperboard press 19. Support posts 20 are provided with screws 21, which are rotatably connected to the paperboard press 19 and drive the paperboard press 19 to move up and down. Thus, the support posts 20 provide sufficient support, allowing the paperboard press 19 to be stably positioned between the two support posts 20. The screws 21 provide high precision, keeping the paperboard press 19 stably parallel to the table 2, and providing a high degree of pressure.

[0036] In some embodiments, as Figure 5 、 6 As shown, the push paper board 3 is divided into two pieces separated from each other, and the adjacent space between the two push paper boards 3 serves as a gap 5.

[0037] like Figure 6 As shown, a support plate 10 is provided on the rear side of the pushing paper board 3 , and the support plate 10 is arranged perpendicular to the rear side of the pushing paper board 3 , and a rack 9 is provided on the lower side of the support plate 10 .

[0038] In some embodiments, as Figure 5 、 6 As shown, each push paper board 3 is provided with a support plate 10 at the rear side, and a T-shaped structure is formed between the support plate 10 and the push paper board 3, and the two support plates 10 are respectively a first support plate 10.1 and a second support plate 10.2. In this way, a more stable pushing structure is provided.

[0039] In some embodiments, as Figure 5 、 6 As shown, the electric propulsion mechanism includes an electric motor 6, a rotating shaft 7, a gear 8, and a rack 9. The rack 9 is connected to or integrally formed with the pusher board 3. The gear 8 is axially mounted on the rotating shaft 7. The electric motor 6 is in driving connection with the rotating shaft 7. The rotating shaft 7 drives all the gears 8 to rotate synchronously. The synchronous rotation of the gears 8 drives the rack 9 forward / reverse, thereby advancing / retracting the pusher board 3. This provides high reliability and propulsion force, as well as high synchronization accuracy. The electric motor 6 can be, for example, a stepper motor or a servo motor.

[0040] The electric propulsion mechanism may also be other structures, such as an electric linear push rod, an electric crank-connecting rod mechanism, etc. Any electric propulsion mechanism applicable to the present disclosure may be applied to the present disclosure.

[0041] In some embodiments, as Figure 5 、 6 As shown, the support plates 10 are sequentially distributed along the axial direction of the rotating shaft 7 , and a rack 9 is provided on the lower side of each support plate 10 . Each rack 9 meshes with a corresponding gear 8 , and the gears 8 are sequentially distributed along the axial direction of the rotating shaft 7 .

[0042] In some embodiments, as Figure 6 、 8 As shown, a positioning baffle 17 is provided on the same side of the two racks 9 away from the electric motor 6. The two positioning baffles 17 are used to limit the two gears 8 on one side of the axial direction when the gears 8 and the racks 9 are assembled. In this way, assembly is facilitated.

[0043] In some embodiments, as Figure 5 、 8 As shown, a sensor 11 is further included, and the sensor 11 cooperates with the support plate 10 so that the sensor 11 detects the stroke of the support plate 10. In this way, better stroke control is achieved.

[0044] Furthermore, the sensor 11 is a photoelectric sensor 11 , and the support plate 10 is provided with detection holes 12 in sequence along its moving direction.

[0045] Of course, other sensors 11 may also be used, and any sensor 11 applicable to the present disclosure may be applied in the present disclosure.

[0046] In some embodiments, as Figure 3 、 4 As shown, the workbench 1 is provided with a guide groove 13, and the support plate 10 is guided and matched with the guide groove 13. During assembly, the support plate 10 can be matched with the guide groove 13 up and down first, and then the pressure cover 18 is installed. In this way, it is not only convenient to assemble, but also conducive to assembly accuracy.

[0047] In some embodiments, as Figure 2 As shown, the rear end of the support plate 10 is provided with a limit portion 14, which cooperates with the rear end surface 15 of the guide groove 13 to limit the forward direction of the support plate 10. This helps prevent the support plate 10 from being pushed forward excessively in the event of a fault, improves safety, and has a simple and reliable structure.

[0048] In some embodiments, as Figure 6 、 8 As shown, the lower side of the support plate 10 is provided with an open groove 16 that opens downwards, and the open groove 16 is used to reduce the contact area between the lower side of the support plate 10 and the bottom surface of the guide groove 13. This is conducive to pushing the support plate 10 smoothly and reducing the influence of friction.

[0049] In some embodiments, as Figure 6 As shown, the lower side of the rack 9 protrudes from the lower side of the support plate 10. The length of the rack 9 is shorter than that of the support plate 10. When the gear 8 is disengaged from the front end of the rack 9, the support plate 10 reaches the maximum retracted position in the retracted direction. This helps prevent the support plate 10 from excessively retracting in the event of a fault, improves safety, and has a simple and reliable structure.

[0050] In some embodiments, as Figure 1 、 4 As shown, the guide groove 13 is provided by a support block installed on the workbench 1. The support block can be, for example, a whole support block corresponding to the first support plate 10.1, or it can be composed of multiple support blocks arranged in sequence along the forward / backward direction, such as two support blocks corresponding to the second support plate 10.2.

[0051] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0052] The above description is merely an illustrative embodiment of the present invention, and therefore any equivalent changes or modifications made according to the structure, features and principles described in the scope of protection of the present invention are included in the scope of protection of the present invention.
