[0024] Please see Figure 1 - Figure 4 A cardboard box punching device includes a workbench 1, a punching component, a clamping component, and a collecting component. The workbench 1 has multiple support legs 2 at its bottom, the clamping component is installed inside the workbench 1, and the collecting component is installed at the bottom of the workbench 1.

[0025] The workbench 1 is equipped with a mounting bracket 3 on the top. An electric telescopic rod 4 is installed in the center of the top of the inner wall of the mounting bracket 3. A first motor 401 is installed above the mounting bracket 3 on the top of the electric telescopic rod 4. A mounting plate 5 is fixedly connected to the bottom of the electric telescopic rod 4. The four corners of the bottom of the mounting plate 5 are fixedly connected to the top of the telescopic rod 12. The bottom of the telescopic rod 12 is fixedly connected to the four corners of the top of the pressure plate 11. A spring 13 is sleeved on the outer periphery of the telescopic rod 12. A punch hole 1102 is provided in the middle of the pressure plate 11. A scale 1101 is provided on the inner wall of the punch hole 1102 on the side away from the screw 10. A punching assembly is provided on the mounting plate 5.

[0026] The drilling assembly includes a first slider 6, a mounting head 7, a drilling head 8, a limiting plate 9, and a screw 10. The bottom of the mounting plate 5 is provided with a second slot 501, in which multiple first sliders 6 are engaged. The bottom of the first slider 6 is fixedly connected to the mounting head 7, and the bottom of the mounting head 7 is detachably connected to the drilling head 8.

[0027] The mounting plate 5 has through holes 502 at both ends on the front side. The through holes 502 are connected to the second slot 501. A screw 10 is threaded into the through hole 502. A limit plate 9 is provided on the side of the first slider 6 in the second slot 501 near the through hole 502.

[0028] Through the above technical solution, the mounting bracket 3 on the top of the workbench 1 provides a mounting base for the electric telescopic rod 4. The first motor 401 drives the electric telescopic rod 4 to extend and retract, which can drive the mounting plate 5 to move up and down. The mounting plate 5 is connected to the pressure plate 11 through the telescopic rod 12. The spring 13 sleeved on the outer periphery of the telescopic rod 12 can play a buffering and pre-pressing role when the pressure plate 11 contacts the carton, ensuring the stability of the carton when punching. The punching opening 1102 in the middle of the pressure plate 11 provides working space for the punching head 8. The scale 1101 on its inner wall facilitates accurate positioning of the punching position.

[0029] In the drilling assembly on the mounting plate 5, the second slot 501 provides a sliding track for the first slider 6, allowing the first slider 6 to flexibly adjust the position of the mounting head 7 and the drilling head 8. The detachable connection between the mounting head 7 and the drilling head 8 facilitates the replacement of drilling heads 8 of different specifications. The screw 10 connected to the internal thread of the through hole 502 on the front of the mounting plate 5 can push the limiting plate 9 in the second slot 501 to stably limit the first slider 6 after it has been adjusted, ensuring the accuracy of the drilling position.

[0030] This utility model provides a technical solution, wherein the clamping assembly includes a bidirectional lead screw 14, a limiting block 15, and a second slider 16;

[0031] On both sides of the workbench 1 away from the mounting bracket 3, there are first slots 101. A bidirectional lead screw 14 is installed in the first slot 101. One end of the bidirectional lead screw 14 is rotatably connected to the inner wall of the first slot 101, and the other end of the bidirectional lead screw 14 is drivenly connected to the output end of the second motor 1401 installed on the side wall of the workbench 1. A limit block 15 is installed in the middle of the bidirectional lead screw 14 in the first slot 101. A second slider 16 is threadedly connected to both sides of the limit block 15 of the bidirectional lead screw 14. A clamping plate 1601 is fixedly connected to the top of the second slider 16. A rubber anti-slip layer is provided on the side of the clamping plate 1601 near the mounting plate 5.

[0032] Through the above technical solution, the first slot 101 provides installation and movement space for the bidirectional lead screw 14 and the second slider 16. The second motor 1401 drives the bidirectional lead screw 14 to rotate, which can drive the second sliders 16 on both sides of the limiting block 15 to move synchronously in opposite directions. This allows the clamping plate 1601 on the top of the second slider 16 to clamp cartons of different sizes. The rubber anti-slip layer on the clamping plate 1601 can enhance the clamping friction and prevent the cartons from sliding.

[0033] This utility model provides a technical solution. The collection component includes a collection box 17. Dovetail protrusions 1701 are provided on both sides of the top of the collection box 17. A dovetail groove 103 is provided on the bottom of the workbench 1 corresponding to the dovetail protrusions 1701. The collection box 17 and the workbench 1 are detachably connected by the mortise and tenon joint between the dovetail protrusions 1701 and the dovetail groove 103.

[0034] Through the above technical solution, the collection box 17 is used to receive the waste generated by drilling. The dovetail protrusions 1701 on both sides of its top are detachably connected to the dovetail grooves 103 at the bottom of the workbench 1 by mortise and tenon joint, which makes it convenient to remove the collection box 17 at any time for waste cleaning.

[0035] The working principle of this utility model is as follows:

[0036] First, place the carton to be punched on the workbench 1 and start the second motor 1401, which drives the bidirectional lead screw 14 to rotate. Since the threads on both sides of the upper limit block 15 of the bidirectional lead screw 14 are opposite, it will drive the second sliders 16 on both sides to move synchronously towards each other in the first slot 101, thereby causing the clamping plate 1601 on the top of the second slider 16 to approach and clamp the carton. The rubber anti-slip layer on the clamping plate 1601 enhances the friction and prevents the carton from sliding during the punching process.

[0037] According to the punching requirements, the positions of the mounting head 7 and the punching head 8 are adjusted by sliding the first slider 6 in the second slot 501 at the bottom of the mounting plate 5. After the position is determined, the screw 10 in the through hole 502 on the front of the mounting plate 5 is turned to push the limiting plate 9 in the second slot 501 to press the first slider 6, thereby fixing the punching position. At the same time, punching heads 8 of the corresponding specifications and quantities can be installed on the mounting head 7 as needed. Then, the first motor 401 is started to drive the electric telescopic rod 4 to extend, which drives the mounting plate 5 to move downward. The mounting plate 5 drives the pressure plate 11 to move downward synchronously through the telescopic rod 12. When the pressure plate 11 contacts the carton, the spring 13 on the outer periphery of the telescopic rod 12 is compressed. The elastic force of the spring 13 makes the pressure plate 11 press tightly on the carton, pre-fixing the carton. The scale 1101 on the inner wall of the punching hole 1102 in the middle of the pressure plate 11 can help confirm the alignment position of the punching head 8. As the electric telescopic rod 4 continues to extend, the mounting plate 5 continues to move downward, and the punching head 8 passes through the punching hole 1102 of the pressure plate 11 to punch holes in the carton. The waste generated by punching falls into the collection box 17 at the bottom through the collection trough 102 in the middle of the workbench 1.

[0038] After drilling is completed, the electric telescopic rod 4 retracts, causing the mounting plate 5 and the drilling head 8 to return to their original positions. The pressure plate 11 also separates from the cardboard box under the action of the spring 13. Finally, the second motor 1401 is turned off, the bidirectional lead screw 14 rotates in the opposite direction, the clamping plate 1601 releases the cardboard box, and the cardboard box can be removed. When there is a large amount of waste in the collection box 17, the collection box 17 can be pulled out from the bottom of the workbench 1 through the mortise and tenon joint structure between the dovetail protrusion 1701 and the dovetail groove 103, the waste can be cleaned, and then it can be reinstalled in its original position.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
