[0021] Put the cardboard on the conveyor belt to transport it forward, start the forward and reverse motors to drive the screw to rotate, so that the two moving plates move toward each other on the screw, which drives the two side plates to move toward each other, thereby driving the two cutters to move toward each other, until the front ends of the two cutters move to the length position required for cutting on the packaging cardboard, and start the hydraulic telescopic rod to drive the creasing knife down;

[0022] A mounting box 13 with a double-headed screw 2 rotatably mounted therein is disposed on one side of the top plate 1 and on the mounting frame 6 in parallel with the creasing knife 15. The mounting box 13 has an opening relative to one side of the creasing knife 15. A movable plate 12 with side plates 10 mounted therein is sleeved on both ends of the double-headed screw 2 and is located inside the opening. A slide groove 18 with a slider 3 slidably connected thereto is provided on opposite sides of the two side plates 10 in a vertical direction. A first elastic member 17 and a second elastic member 4 are disposed between the two sides of the slider 3 and the inner wall of the slide groove 18, respectively. A mounting plate 16 is disposed on the opposite sides of the two sliders 3 in parallel with the creasing knife 15, and a cutting knife 9 is mounted on the bottom of the mounting plate 16.

[0023] During the descent process of the creasing knife, it first contacts the mounting plate at the top of the cutter, thereby driving the cutter at the bottom of the mounting plate to descend together. The cutter first contacts the two sides of the packaging cardboard to cut it. After the cutting is completed, the forward and reverse motors drive the lead screw to rotate in the opposite direction to drive the cutter to return to its original position. When the top of the mounting plate is separated from the bottom of the creasing knife, the mounting plate drives the cutter to return to its original position under the elastic force of the first spring and the second spring, waiting for the next work.

[0024] A forward and reverse motor 11 for driving the double-headed screw 2 to rotate is arranged on the outer wall of the installation box 13 .

[0025] The length of the installation box 13 is greater than the distance between the two installation frames 6 .

[0027] Embodiment 2: A corrugated cardboard die-cutting device, comprising: a mounting frame 6, a conveyor belt 5 arranged between two mounting frames 6, a top plate 1 with a hydraulic telescopic rod 14 installed on the top, located above the conveyor belt 5 and on the mounting frame 6, a creasing knife 15 located between the top plate 1 and the conveyor belt 5 and fixedly connected to the movable end of the hydraulic telescopic rod 14;

[0028] A mounting box 13 with a double-headed screw 2 rotatably mounted therein is disposed on one side of the top plate 1 and on the mounting frame 6 in parallel with the creasing knife 15. The mounting box 13 has an opening relative to one side of the creasing knife 15. A movable plate 12 with side plates 10 mounted therein is sleeved on both ends of the double-headed screw 2 and is located inside the opening. A slide groove 18 with a slider 3 slidably connected thereto is provided on opposite sides of the two side plates 10 in a vertical direction. A first elastic member 17 and a second elastic member 4 are disposed between the two sides of the slider 3 and the inner wall of the slide groove 18, respectively. A mounting plate 16 is disposed on the opposite sides of the two sliders 3 in parallel with the creasing knife 15, and a cutting knife 9 is mounted on the bottom of the mounting plate 16.

[0029] The two moving plates are driven by a screw rod to approach each other so that the two mounting plates are located below the cutting knife. The cutting knife then descends to press the cutting knife on the mounting plate downward to cut the material on the conveyor belt. After the cutting is completed, the two moving plates are driven to move back to each other by reversing the screw rod, thereby eliminating the obstruction to the cutting knife, allowing the cutting knife to descend to indent the material. The distance between the two cutting knives can be adaptively adjusted to meet different cutting requirements, thereby realizing automatic adjustment of the cutting position, avoiding the need to manually adjust the material position, reducing the labor intensity of personnel, and improving the applicability of the device.

[0030] A forward and reverse motor 11 for driving the double-headed screw 2 to rotate is arranged on the outer wall of the installation box 13 .

[0031] The length of the installation box 13 is greater than the distance between the two installation frames 6 .

[0032] The top of the mounting frame 6 is provided with a notch 8 for the cutter 9 to pass through.

[0033] When the distance between the two movable plates 12 is the largest, the distance between the mounting plates 16 is greater than the length of the creasing knife 15;

[0034] The creasing knife has no obstruction, and the hydraulic telescopic rod directly drives the creasing knife down to contact the remaining position of the middle part of the packaging cardboard to crease it, so that different creasing and incision lengths can be adjusted without manual adjustment of the position of the packaging cardboard.

[0035] A support column 7 is provided between the top plate 1 and the mounting frame 6 .

[0036] The working principle is:

[0037] When in use, place the cardboard on the conveyor belt and transport it forward, start the forward and reverse motors to drive the screw rod to rotate, so that the two moving plates move toward each other on the screw rod, which drives the two side plates to move toward each other, thereby driving the two cutters to move toward each other, until the front ends of the two cutters move to the length position required for cutting on the packaging cardboard, start the hydraulic telescopic rod to drive the creasing knife to descend, and the creasing knife first contacts the mounting plate at the top of the cutter during the descending process, thereby driving the cutter at the bottom of the mounting plate to descend together, and the cutter first contacts the two sides of the packaging cardboard to cut it, and after the cutting is completed, the forward and reverse motors drive the screw rod to rotate in the opposite direction to drive the cutter to return to its original position, and when the top of the mounting plate is separated from the bottom of the creasing knife, the mounting plate drives the cutter to return to its original position under the elastic force of the first spring and the second spring, and waits for the next work;

[0038] At this time, the creasing knife has no obstruction, and the hydraulic telescopic rod directly drives the creasing knife down and contacts the remaining position of the middle part of the packaging cardboard to crease it, so that different creasing and incision lengths can be adjusted without manual adjustment of the position of the packaging cardboard.

[0039] When the above-mentioned corrugated cardboard die-cutting equipment is used, the two movable plates are driven to approach each other by a screw rod, so that the two mounting plates are located below the cutting knife. The cutting knife then descends to press the cutting knife on the mounting plate downward to cut the material on the conveyor belt. After the cutting is completed, the two movable plates are driven to move back to each other by reversing the screw rod, thereby losing the obstruction to the cutting knife, so that the cutting knife can descend to indent the material. The distance between the two cutting knives can be adaptively adjusted to meet different cutting requirements, and automatic adjustment of the cutting position can be achieved, avoiding the need to manually adjust the material position, reducing the labor intensity of personnel, and improving the applicability of the device.
