[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0023] The embodiment of the present invention provides a voucher punching device.
[0024] As Figure 1 shown, it includes a punching machine body 1. A punching operation groove is opened on the lower side of the front end of the punching machine body 1. A punching platform 2 is installed on the lower side of the punching machine. Sliding grooves are opened on the left and right sides of the punching platform 2, and a positioning component is slidably installed on the sliding grooves.
[0025] As Figure 2 shown, a positioning component is slidably installed on the sliding grooves. The positioning component includes a positioning beam frame 3, a sliding beam plate 4, and a clamping beam 5. Sliding blocks are arranged on the left and right sides of the positioning beam frame 3, and the sliding blocks are slidably installed in the sliding grooves. Two mounting blocks are arranged on the left and right sides of the positioning beam frame 3. A driving lead screw 6 and a guide rod 8 parallel to the driving lead screw 6 are horizontally arranged between the two mounting frames. One end of the driving lead screw 6 is connected to a positioning motor 7. A driving nut 9 is arranged on the lower side of the sliding beam plate 4, and the driving nut 9 is threadedly connected to the driving lead screw 6. When the positioning motor 7 rotates, it can drive the driving nut 9 to move left and right on the driving lead screw 6 to drive the sliding beam plate 4 to clamp and horizontally slide the bill voucher left and right, so that multiple binding holes on the bill voucher are kept on the same horizontal line. A guide hole is arranged on the driving nut 9, and the guide rod 8 slidably passes through the guide hole.
[0026] As Figure 2 、 3As shown, an infrared centering switch is installed between the sliding beam 4 and the positioning beam 3, and the infrared centering switch includes an infrared transmitter 10 and an infrared receiver 11. A horizontal slide rail is provided on the positioning beam 3, and a toggle block 12 is slidably installed on the horizontal slide rail. A damping bow piece 13 is fixed on the toggle block 12, and the damping bow piece 13 abuts against the positioning beam 3. The infrared receiver 11 is installed on the toggle block 12, and the infrared transmitter 10 is fixed on the lower side of the driving nut 9 facing the toggle block 12. Manually toggling the toggle block 12 can adjust the horizontal position of the infrared receiver 11, which can be used to limit the movement displacement of the sliding beam, facilitate the control of the positioning motor 7, and ensure that the binding holes of multiple batches of bills and vouchers remain in the same position to avoid misalignment of the binding holes and cause binding misalignment.
[0027] Support screws 13 are provided on the left and right sides of the sliding beam plate 4, and the two ends of the clamping beam 5 are slidably installed on the support screws 13. A clamping spring 14 is fixedly connected between the clamping beam 5 and the sliding beam plate 4. An adjusting nut 9 is threadedly connected to the upper end of the support screw 13, and the adjusting nut 9 is in contact with the upper side of the clamping beam 5. Rotating the adjusting nut 9 can complete the clamping and fixing of the bill voucher by the clamping beam 5 to avoid the bill voucher from being pressed and deviated during the punching process.
[0028] The right end of the sliding beam 4 is provided with a support plate 15 extending toward the punching machine body 1, and the front end of the support plate 15 is bent inward 90° to have a positioning piece 16. The positioning piece 16 bent inward can abut against the front end of the bill voucher to ensure that multiple batches of bill vouchers maintain the same clamping position.
[0029] A positioning nut 16 is provided on the outer side of the support plate 15, and a positioning strut 17 is threadedly connected to the positioning nut 16. The front end of the positioning strut 17 abuts against the inner wall of the punching operation groove of the punching machine body 1. The positioning strut 17 can position the forward and backward sliding position of the positioning component to ensure that the distance between the punching position and the front side of the bill voucher remains consistent when punching multiple batches of bills.
[0030] like Figure 1 As shown, an inner groove is opened on the upper side of the punching platform 2, and the positioning component is placed in the inner groove. The upper side of the sliding beam plate is flush with the punching platform 2, which can ensure that the bill voucher is placed horizontally on the punching platform 2, facilitate the punching operation, and avoid the tilt of the binding hole caused by tilted punching of the bill voucher.
[0031] One end of the positioning beam 3 is rotatably connected with an adjusting rod, and the lower end of the adjusting rod is provided with an adjusting gear 18. An adjusting rack 19 is fixed on the side wall of the punching platform 2, and the adjusting gear 18 and the adjusting rack 19 are meshed with each other. An adjusting knob is provided on the upper side of the adjusting rod, and the upper side surface of the adjusting gear 18 slides and contacts against the lower edge of the sliding block. A limiting ring groove is provided on the upper side surface of the adjusting gear 18, and a limiting protrusion is provided on the lower side of the sliding block. The limiting protrusion is slidably connected in the limiting ring groove. Rotating the adjusting gear 18 can realize the front and rear adjustment of the positioning assembly under the action of the mutual meshing of the segment gear and the adjusting rack 19.
[0032] Workflow:
[0033] In the present invention, the adjusting gear 18 is rotated to make the positioning assembly as a whole retreat on the adjusting rack 19, which is convenient for clamping the bill voucher. The front side of the bill voucher contacts the inner side of the positioning piece 16. After the clamping is completed, the positioning assembly is adjusted forward until the positioning support rod 17 contacts the inner wall of the punching operation slot of the punching machine body 1. The positioning support rod 17 can be rotated to fine-tune the front and rear positions of the positioning assembly so that the distance between the punching position and the front edge of the bill voucher is maintained at a suitable position. The positioning of the bill voucher can be completed, and the first punching can be performed. The positioning motor 7 is rotated to make the sliding beam plate 4 slide horizontally to the right. When the infrared transmitter 10 and the infrared receiver 11 are aligned, the trigger switch is turned off and the positioning motor 7 is turned off, and the next punching can be carried out. When the punching is completed, the positioning component is adjusted by adjusting the gear 18, the bill voucher is removed, and the next batch of bill vouchers are installed, and the positioning component is slid forward again until the positioning support rod 17 hits the inner wall of the punching operation slot of the punching machine body 1. During this process, the positions of the positioning support rod 17 and the toggle block 12 are kept unchanged, the distance between the punching positions on the front and rear sides and the front side of the bill voucher is consistent, and the spacing between the multiple binding holes is also consistent, which can ensure that the binding holes of multiple batches of bill vouchers remain aligned.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
