Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Referring to Figures 1-7 , a carton packaging punching device includes a base 1, an L-shaped support arm 2 is fixedly installed on the base 1, a telescopic cylinder 3 is fixedly installed on the support arm 2, a rectangular mounting pipe 4 is fixedly installed on the output shaft of the telescopic cylinder 3, a U-shaped ejector rod 5 is fixedly installed on the side of the mounting pipe 4 through a fixing rod, and the telescopic cylinder 3 can drive the mounting pipe 4 to move vertically downward, and then drive the ejector rod 5 to press down through the mounting pipe 4.

[0027] There are two parallel grooves on the upper surface of the base 1. Sliders 6 are slidably installed in both of the two parallel grooves. Telescopic springs 7 are provided in both of the two parallel grooves. One end of the telescopic spring 7 is fixedly installed on the slider 6, and the other end is fixedly installed on the inner wall of the parallel groove. Positioning plates 8 are respectively fixedly installed on the upper surfaces of the two sliders 6. Inclined plates 9 are fixedly installed on both of the two positioning plates 8. When the ejector rod 5 is pressed down, the two ends of the ejector rod 5 are respectively in sliding contact with the two inclined plates 9. The two inclined plates 9 approach each other due to the extrusion of the ejector rod 5, and then drive the positioning plates 8 to approach each other. The telescopic spring 7 is compressed, so as to realize the left and right positioning of the carton. Positioning blocks 10 are fixedly installed on the positioning plates 8. When placing the carton, when one end of the carton touches the positioning block 10, the front and back positioning of the carton is realized.

[0028] Support plates 11 are symmetrically and fixedly installed on the base 1. A connecting rod 12 is fixedly installed between the two support plates 11. A plurality of annular cutters 13 with different diameters are connected to the connecting rod 12 through a support assembly. A connecting component for connecting the annular cutter 13 is provided on the installation pipe 4.

[0029] The support assembly includes two support rods 14 symmetrically and fixedly installed on the annular cutter 13, two fixing blocks 15 respectively fixedly installed on the two support rods 14, and a support spring 16 sleeved on the support rod 14. The two ends of the support spring 16 are respectively fixedly connected to the fixing block 15 and the connecting rod 12. In the natural state, the unused annular cutter 13 is supported on the connecting rod 12 under the action of the support spring 16. The support assembly mainly plays a role in supporting the unused annular cutter 13.

[0030] The connecting component includes a gear 17, two racks 18, two U-shaped blocks 19, two sleeve rods 20 and a connecting part. A strip-shaped hole and two rectangular holes are opened on the lower surface of the installation pipe 4. The gear 17 is rotatably installed at the center of the installation pipe 4. The two racks 18 are symmetrically and slidably arranged on the installation pipe 4. U-shaped blocks 19 are horizontally slidably installed in the two rectangular holes. One end of the U-shaped block 19 is fixedly connected to the rack 18, and the other end is slidably inserted into the strip-shaped hole. The gear 17 is meshed with the two racks 18. The two U-shaped blocks 19 are respectively fixedly installed on the two racks 18. The two sleeve rods 20 are respectively vertically and fixedly installed on the lower surfaces of the two U-shaped blocks 19. A connecting hole is opened at the lower end of the sleeve rod 20. Circular holes communicating with the connecting hole are opened on the sides of the two sleeve rods 20. The connecting part is used to connect the sleeve rod 20 and the support rod 14. The connecting part includes a screw 21 and a nut 22. The circular hole on the sleeve rod 20 is aligned with the threaded hole on the support rod 14. One end of the screw 21 passes through the threaded hole and the circular hole, and the nut 22 is in threaded cooperation with the screw 21. A rotating shaft is fixedly installed on the side of the gear 17. The rotating shaft passes through the strip-shaped hole opened on the installation pipe 4 and is fixedly installed with a knob 23.

[0031] When the annular cutting tool 13 needs to be replaced, first unscrew the screw 21. The screw 21 is separated from the nut 22. Start the telescopic cylinder 3. The output shaft on the telescopic cylinder 3 drives the mounting pipe 4 to move vertically upward. Then the mounting pipe 4 drives the sleeve rod 20 to move vertically upward. The support rod 14 is separated from the sleeve rod 20. Rotate the knob 23, and the gear 17 rotates with the knob 23, thereby driving the rack 18 to move closer to or away from each other. Under the action of the U-shaped block 19, drive the sleeve rod 20 to move closer to or away from each other. Wait until the sleeve rod 20 moves to the same vertical line as the support rod 14 fixed on the required annular cutting tool 13. Start the telescopic cylinder 3. The output shaft on the telescopic cylinder 3 drives the mounting pipe 4 to move vertically downward. Then the mounting pipe 4 drives the sleeve rod 20 to move vertically downward. The support rod 14 on the required annular cutting tool 13 is inserted into the connection hole of the sleeve rod 20. When the circular hole of the sleeve rod 20 coincides with the threaded hole of the support rod 14, use the screw 21 to pass through the coincident holes of the sleeve rod 20 and the support rod 14, and tighten and fix the nut 22 on the screw 21.

[0032] Limit blocks 24 are fixedly installed on both of the two positioning plates 8. The longitudinal section of the limit block 24 is trapezoidal. When punching the cardboard box, the annular cutting tool 13 generates pressure on the center of the cardboard box, and the limit blocks 24 limit both sides of the cardboard box to prevent warping.

[0033] In the present utility model, when punching the cardboard box, first place the cardboard box to be punched on the base 1 until one end of the cardboard box touches the two positioning blocks 10 and is located between the two positioning plates 8. At this time, start the telescopic cylinder 3. The output shaft on the telescopic cylinder 3 drives the mounting pipe 4 to move vertically downward, thereby driving the ejector rod 5 to move downward. Under the action of the inclined surfaces of the two inclined plates 9, the ejector rod 5 slides relative to the inclined plates 9, and the two inclined plates 9 move closer to each other. Then drive the two positioning plates 8 on the inclined plates 9 to move closer to each other until the two positioning plates 8 contact both sides of the cardboard box, driving the cardboard box to move to the center of the upper surface of the base 1 and be directly below the annular cutting tool 13, thus realizing automatic positioning of the cardboard box, without manual intervention, improving work efficiency, ensuring the accuracy of punching, and being convenient to operate.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
