DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an embodiment: a corrugated cardboard die-cutting device, comprising a base 1, a U-shaped plate 4 and a lifting plate 9, the U-shaped plate 4 is installed on the top of the base 1, and a motor 17 is installed at one end of the bottom of the U-shaped plate 4, where the model of the motor 17 can be Y90S-2, first sliding components 18 are installed at both ends of the inside of the U-shaped plate 4, and the lifting plate 9 is slidably installed on the inner side of the first sliding component 18, a die-cutting knife 10 is installed at the bottom of the lifting plate 9, and a first rectangular frame 7 is installed at the edge of the bottom of the lifting plate 9, and a second rectangular frame 16 is installed inside the first rectangular frame 7, a control panel 2 is installed on the top of the base 1 away from the motor 17, and the output end of the control panel 2 is electrically connected to the input end of the motor 17 through a wire.

[0022] In this implementation:

[0023] Furthermore, a rotating shaft 15 is installed at the output end of the motor 17, and an extrusion protrusion 14 is installed at the end of the rotating shaft 15 away from the motor 17. A group of protrusions 21 are symmetrically arranged on the outer side of the extrusion protrusion 14. When in use, the motor 17 drives the extrusion protrusion 14 to rotate at a constant speed through the rotating shaft 15, so that the protrusion 21 on the extrusion protrusion 14 repeatedly squeezes the roller 13, which can be reciprocated by the die-cutting knife 10, so that the die-cutting knife 10 can automatically and continuously die-cut the corrugated cardboard. The device has a high degree of automation and is relatively convenient to use.

[0024] Furthermore, bearings 11 are installed at both ends of the top of the lifting plate 9, and a rotating rod 12 is installed inside the bearing 11, and a roller 13 is installed on the outside of the rotating rod 12. When the extrusion protrusion 14 rotates, the roller 13 contacts the extrusion protrusion 14, and the roller 13 can rotate with the extrusion protrusion 14, which will not affect the rotation of the extrusion protrusion 14, which is conducive to ensuring the normal progress of the die-cutting process.

[0025] Furthermore, a fixing plate 5 is installed on the inner side of the U-shaped plate 4, and a return spring 6 is installed on the top of the fixing plate 5. The end of the return spring 6 away from the fixing plate 5 is connected to the lifting plate 9. When the protrusion 21 on the extrusion protrusion 14 rotates to a position away from the roller 13, the extrusion protrusion 14 no longer squeezes the roller 13. At this time, the elastic action of the return spring 6 pushes the lifting plate 9 to move upward and reset. The lifting plate 9 drives the die-cutting knife 10 and the second rectangular frame 16 to move together, so that the die-cutting knife 10 and the second rectangular frame 16 can be kept away from the corrugated cardboard.

[0026] Furthermore, second sliding components 19 are installed at both ends of the first rectangular frame 7, and guide sliders 20 are slidably installed on the inner side of the second sliding components 19. The ends of the guide sliders 20 away from the second sliding components 19 are connected to the second rectangular frame 16. The second rectangular frame 16 is guided by the guide sliders 20 so that the second rectangular frame 16 can only move in a straight line in the vertical direction.

[0027] Furthermore, telescopic springs 8 are installed at both ends of the top of the second rectangular frame 16, and the ends of the telescopic springs 8 away from the second rectangular frame 16 are connected to the lifting plate 9. The second rectangular frame 16 first contacts the corrugated cardboard, and the elastic action of the telescopic springs 8 pushes the second rectangular frame 16, so that the second rectangular frame 16 and the corrugated cardboard are tightly fitted, and the corrugated cardboard can be pressed firmly by the second rectangular frame 16.

[0028] Furthermore, a die-cutting groove 3 is provided on the top of the base 1 , and during die-cutting, the die-cutting knife 10 can be inserted into the die-cutting groove 3 , thereby facilitating die-cutting of the corrugated cardboard by the die-cutting knife 10 .

[0029] Working principle:

[0030] When in use, the device is connected to a power source, and then the corrugated cardboard is placed on the top of the base 1 for die cutting;

[0031] During die cutting, the staff can start the motor 17 through the control panel 2, so that the motor 17 drives the extrusion protrusion 14 to rotate at a constant speed through the rotating shaft 15;

[0032] When the protrusion 21 on the squeezing convex block 14 rotates to contact the roller 13, the squeezing convex block 14 squeezes the roller 13, so that the roller 13 is stressed and pushes the lifting plate 9 to move downward;

[0033] At this time, the second rectangular frame 16 first contacts the corrugated cardboard, and the elastic action of the telescopic spring 8 pushes the second rectangular frame 16, so that the second rectangular frame 16 and the corrugated cardboard are closely fitted, that is, the corrugated cardboard can be firmly pressed by the second rectangular frame 16, and the lifting plate 9 continues to move downward, so that the die-cutting knife 10 contacts the corrugated cardboard, and the corrugated cardboard can be die-cut by the die-cutting knife 10;

[0034] When the protrusion 21 on the squeezing convex block 14 rotates to a position away from the roller 13, the squeezing convex block 14 no longer squeezes the roller 13. At this time, the elastic action of the reset spring 6 causes it to push the lifting plate 9 to move upward and reset. The lifting plate 9 drives the die cutter 10 and the second rectangular frame 16 to move together, so that the die cutter 10 and the second rectangular frame 16 can be away from the corrugated board.

[0035] Since the motor 17 drives the extrusion protrusion 14 to rotate at a constant speed through the rotating shaft 15, the protrusion 21 on the extrusion protrusion 14 repeatedly squeezes the roller 13, and the die-cutting knife 10 can move back and forth, so that the die-cutting knife 10 can automatically and continuously die-cut the corrugated cardboard. The device has a high degree of automation and is more convenient to use.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
