[0037] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0038] This embodiment proposes a drilling pad control mechanism, such as... Figure 1 As shown, the assembly includes a mounting plate 10, a placement component 20 for placing the rubber pad 40, and a drive component 30 for driving the rubber pad 40 to rotate. The placement component 20 is placed on the mounting plate 10, and the drive component 30 is located below the mounting plate 10. The mounting plate 10 has a rectangular through-hole groove 11, and a rack 12 is arranged beside the groove 11. The placement component 20 includes a slide plate 21 that mates with the groove 11, and a gear 22 that is placed below the slide plate 21 and fixedly engaged with the slide plate 21. The rubber pad 40 is embedded in the slide plate 21 and coaxially arranged with the gear 22.

[0039] The driving assembly 30 drives the slide plate 21 to reciprocate along the length direction of the slide groove 11, so that the gear 22 and the rack 12 are engaged, and then the gear 22 drives the rubber pad 40 to rotate in one direction, so that the hole position on the rubber pad 40 is automatically replaced every time a hole is punched. The control mechanism for controlling the one-way circulation and alternating use of the hole positions on the rubber pad 40 can not only relieve the extrusion of the rubber pad 40 caused by continuous punching, so that the rubber pad 40 always remains elastic, but also improve the damping effect of the rubber pad 40 and the fixing force for stabilizing the paper, so that the paper can be completely punched through, and the service life of the rubber pad 40 is prolonged.

[0040] As shown in Figure 2 , the rack 12 is arranged on the lower bottom surface of the mounting plate, and the teeth thereof are arranged towards the side where the slide groove 11 is located, and a mounting hole with a long circular structure is arranged thereon, which is used to adjust the engagement length of the gear 12 and the gear 22, so that the rotation angle of the gear 22 every time a hole is punched can be adjusted. As can be seen from Figure 1 , a plurality of hole positions are uniformly arranged around the rubber pad 40, and based on these distributed hole positions, the included angle between adjacent hole positions can be known, and then the engagement position of the rack 12 and the gear 22 can be adjusted through the included angle. That is, the rotation angle of the rubber pad 40 can be adjusted every time a hole is punched, so that the hole position is changed when the next hole is punched.

[0041] As shown in Figures 3-4 , the lower end surface of the slide plate 21 is provided with a boss surface matched with the slide groove 11; a circular groove is arranged above one end thereof, the groove is close to the position of the drill bit (omitted), and the rubber pad 40 is embedded in the groove through the tray 24. A notch 26 is arranged on the outer end surface of the groove, which is used to control the awl to lift the tray 24 placed therein through the notch 26, so as to take out the tray 24.

[0042] Correspondingly, the notch 26 is arranged at both ends of one diameter of the tray 24, which is also used to facilitate the taking and placing of the rubber pad 40 through the notch 26. The tray 24 has a circular structure, and the height thereof is less than the thickness of the rubber pad 40, so as to avoid the contact between the tray 24 and the paper during the pressing of the paper.

[0043] The gear 22 is provided with a one-way needle bearing 23, which is connected with the slide plate 21 and the tray 24 through the fixed screw 25. Then, the slide plate 21 is driven to slide, so that the gear 22 is engaged with the rack 12, and the gear 22 can only rotate in one direction under the driving of the one-way needle bearing 23, so that it can be ensured that the rubber pad 40 can only rotate in one direction during the whole punching process, and the gear 22 can drive the rubber pad 40 to rotate by one angle every time a hole is punched, so that the rubber pad 40 can punch the hole positions on the rubber pad 40 in one-way circulation and alternately.

[0044] As shown in Figure 2As shown, the drive assembly 30 is positioned below the mounting plate 10 and includes a drive shaft 31 pivotally connected to the mounting plate 10, a lever 32 fixed on the drive shaft 31, and a connecting rod 33 connecting the lever 32 and the slide plate 21. The drive shaft 31 is driven to rotate, and the slide plate 21 is driven to slide along the length direction of the slide groove 11 via the connecting rod 32.

[0045] Furthermore, lever 32 is fixedly mounted on the end of drive shaft 31 near mounting plate 10. The outer diameter of the end pivotally connected to connecting rod 33 is smaller than the outer diameter of the end connected to drive shaft 31, which improves both the fixed connection and the flexibility of rotation of lever 32 and connecting rod 33. One end of connecting rod 33 is pivotally connected to lever 32, and the other end is connected to slide plate 21 via drive shaft 34. Connecting rod 33 is also pivotally connected to drive shaft 34. Drive shaft 34 is positioned on the end of slide plate 21 away from rubber pad 40, and drive shaft 31 is positioned on the end of mounting plate 10 away from rubber pad 40 in slide plate 21, on the same side as rack 12.

[0046] like Figure 5 As shown, the first hole 41 on the rubber pad 40 is the drill hole corresponding to the first drilling. At this time, the slide plate 21 is set at the end away from the drive shaft 31, that is, the connecting rod 33 and the lever 32 are in the extended state.

[0047] like Figure 6 As shown, after the first drilling is completed, the drive shaft 31 is rotated to drive the connecting rod 33 to retract through the lever 32, and drive the slide plate 21 to move towards the rack 12. The rack 12 drives the gear 22 to rotate through the one-way needle roller bearing 23, and then drives the rubber pad 40 to rotate by a preset angle through the tray 24, so that the first hole 41 rotates.

[0048] Because the unidirectional needle roller bearing 23 can only rotate in one direction, its drive gear 22 does not rotate, and the rubber pad 40 also stops rotating within the tray 24. The slide plate 21 waits for drilling when it returns to the drilling position.

[0049] like Figure 7 As shown, during the second drilling, the drill bit drills at the second hole position 42.

[0050] Repeat the above steps. After each hole is drilled, control gear 22 drives rubber pad 40 to rotate by an angle, continuously and alternately drilling holes along the holes on rubber pad 40 in a one-way cycle.

[0051] In actual work, the number of hole positions on the rubber pad 40 is preset in advance and the hole positions are arranged along the periphery of the rubber pad 40 uniformly, and then the position of the engagement of the adjusting gear and the rack can be set based on the included angle of adjacent hole positions. Based on the performance of the rubber pad 40 and the number of hole positions, the upper limit number of punching of each rubber pad 40 can be inferred, and the system controller can automatically record the number of punching. When the upper limit number of punching of the rubber pad reaches, the system will automatically alarm to replace the rubber pad 40.

[0052] A binding machine is provided with the control mechanism as described above.

[0053] The control mechanism for the rubber pad designed by the application has simple structure and accurate control, can automatically rotate the rubber pad and accurately position and punch and bind, controls the one-way circulation rotation of the rubber pad, automatically replaces the hole position on the rubber pad after each punching, and continuously and alternately punches and binds along the preset hole positions on the rubber pad. Not only the accuracy of the rotation of the rubber pad can be improved, but also the safety of the binding can be improved to ensure that the paper is completely punched through, manual intervention operation is not required, and the replacement can be automatically reminded after the binding for a number of times. The application also provides a binding machine provided with the control mechanism.

[0054] The embodiments of the application are described in detail above, and the content is only the preferred embodiments of the application and cannot be considered to limit the scope of the application. Any equivalent changes and improvements made within the scope of the application should still belong to the patent coverage of the application.
