Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] See also Figure 1-5The utility model provides a technical solution: an automatic punching machine suitable for punching positioning holes in labels, including a support frame 1, a mounting frame 2 fixedly connected to the support frame 1, and further comprising: a cylinder 4 fixedly mounted on the top of the mounting frame 2, a screw 17 fixedly connected to the end of the output shaft of the cylinder 4, a guide column 5 fixedly connected to the mounting frame 2, guide columns 5 evenly distributed on the four sides of the mounting frame 2, a lifting frame 9 vertically slidingly sleeved on the four groups of guide columns 5, a connecting plate 19 fixedly connected to the middle of the top side of the lifting frame 9, the connecting plate 19 is flush with the top of the lifting frame 9, the end of the screw 17 is fixedly connected to the connecting plate 19, and a through slot 20 for accommodating the movement of the bidirectional screw rod 8 is opened on one side of the mounting frame 2 1. The bidirectional screw rod 8 is rotatably mounted on the lifting frame 9. Slide blocks 10 are symmetrically arranged on both sides of the lifting frame 9. A limit slot 901 is provided on the lifting frame 9. The slide blocks 10 pass through the limit slots 901 and slide in conjunction with the limit slots 901. The slide blocks 10 are threadedly mounted on the bidirectional screw rod 8 on the corresponding side. The H-shaped lifting rod 6 is arranged above the lifting frame 9. The internal threaded sleeve 3 is connected to the screw rod 17 through a spiral engagement. The internal threaded sleeve 3 is rotatably mounted on the middle of the lifting rod 6. Guide rods 7 are passed through both sides of the slide block 10. The four groups of cross bars of the lifting rod 6 pass through the four groups of guide rods 7 respectively. The punch 18 is fixedly connected to the two groups of guide rods 7 on the same side. Start the cylinder 4. Under the connection of the screw rod 17 and the guidance of the guide column 5, the lifting frame 9 and the punch 18 are pushed down. The punch 18 passes through the punching slot 20 to punch the positioning hole for the label. The bidirectional screw 8 is rotated, and under the action of the threaded transmission, the two sets of sliders 10 are driven to move synchronously toward or away from each other in the horizontal direction, adjusting the spacing between the two sets of punches 18 to adapt to the positioning holes of labels of different widths. The internal threaded sleeve 3 is rotated, and under the action of the threaded transmission, the lifting rod 6 is driven to drive the guide rod 7, and the guide rod 7 drives the punch 18 to move synchronously upward or downward in the vertical direction, adjusting the height of the punch 18 and improving the practicality of the device. Compared with the existing technology, the present utility model has the function of synchronously adjusting the position of the two sets of punches 18, ensuring that the position adjustment accuracy of the two sets of punches 18 is different, thereby improving the quality of punching.

[0045] Specifically, such as Figure 1 As shown, the feeding mechanism includes: a motorized roller 13 rotatably connected to two sets of fixed seats on the support frame 1; an unpowered roller 14 rotatably mounted between the two sets of fixed seats, symmetrically arranged with the motorized roller 13; and a controller 15 fixedly mounted on the support frame 1 for controlling the start and stop of the motorized roller 13. The label passes through the motorized roller 13 and the unpowered roller 14 and extends into the space below the limit plate 12. When the controller 15 is activated, the motorized roller 13, in conjunction with the unpowered roller 14, automatically feeds the label under the punch 18. The punch 18 then punches the label with a registration hole. The label is continuously transported while the punch 18 intermittently punches holes, completing the label's registration hole punching process.

[0046] Specifically, such as Figure 1 、 Figure 4 and Figure 5 As shown, the apparatus further includes a limit plate 12 and a buffer plate 11. The limit plate 12 is arranged below the lifting frame 9 and is fixedly mounted on the four sets of guide posts 5. There is space between the limit plate 12 and the mounting frame 2 to accommodate the passage of labels. The buffer plate 11 and the limit plate 12 are fixedly connected by countersunk screws 16 arranged on their four sides. The buffer plate 11 and the limit plate 12 are provided with waist-shaped punching grooves 20 of the same position and size, which are adapted to the punch 18. The provision of the limit plate 12 not only serves to position the labels, preventing wrinkles during transportation and ensuring the flatness of the label paper, but also further limits the downward pressing position of the punch 18, preventing damage to the label paper due to inertia during the falling process. The buffer plate 11 is made of flexible material and is relatively thin. Its purpose is to ensure that the puncher 18 does not press and damage the limit plate 12 when punching, and to avoid vibration caused by contact, which would cause the puncher 18 to have low punching accuracy, thereby improving the punching efficiency and quality of the device, protecting parts, increasing the service life of the device, and reducing cost output.

[0047] Working principle: When in use, the label passes through the electric roller 13 and the unpowered roller 14 and extends into the space below the limit plate 12. The controller 15 is started. Under the drive of the electric roller 13, the unpowered roller 14 cooperates to automatically feed the label under the puncher 18. After that, the cylinder 4 is started. Under the connection of the screw 17 and the guiding action of the guide column 5, the lifting frame 9 and the puncher 18 are pushed down. The puncher 18 passes through the punching slot 20 to punch positioning holes for the label. The label is continuously transmitted and the puncher 18 punches holes intermittently, thereby completing the label positioning hole punching work; wherein, the bidirectional screw 8 is rotated, and under the action of the threaded transmission, the two groups of sliders 10 are driven to approach or move away synchronously in the horizontal direction, and the spacing between the two groups of punchers 18 is adjusted to adapt to the positioning holes of labels of different widths; the internal threaded sleeve 3 is rotated, and under the action of the threaded transmission, the lifting rod 6 is driven to drive the guide rod 7, and the guide rod 7 drives the puncher 18 to move synchronously upward or downward vertically to adjust the height of the puncher 18 and improve the practicality of the device. Compared with the prior art, the present invention has the function of synchronously adjusting the positions of the two groups of punchers 18, thereby ensuring that the position adjustment precisions of the two groups of punchers 18 are different and improving the punching quality.

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
