[0006] 2. When processing the cardboard, due to the lack of a structure for assisting the positioning of the cardboard and recovering the waste, it is impossible to recover the waste while assisting the positioning of the cardboard, which reduces the stability of the cardboard processing. Summary of the invention

[0028] A method for using a die-cutting device for cardboard processing comprises the following steps:

[0029] S1. Auxiliary positioning and waste recycling: First, the positioning mechanism is powered on and started, and then the cardboard to be processed is placed on the conveyor belt. Then the electric rotating rod group will drive the conveyor belt to perform reciprocating motion and move the cardboard to the processing position of the die-cutting mechanism. Then the exhaust fan will pump the air at the adsorption plate to the water storage tank and let the air be discharged from the exhaust net. The cardboard will be adsorbed on the adsorption plate due to the negative pressure generated by the air pumped at the adsorption plate. Then the die-cutting mechanism will perform die-cutting processing on the cardboard. When the die-cutting process generates debris, the debris will be pumped into the water storage tank along the adsorption plate. Then the heating plate will heat the water in the water storage tank and let the water generate steam to gradually accumulate in the water storage tank. The debris will contact with the steam to increase its own mass, and then fall into the water storage tank and be collected by the water storage tank;

[0030] S2. Tool replacement: First, power on and start the die-cutting mechanism, then adjust the hydraulic rod to drive the adjusting top plate to move the transmission frame plate downward until the die-cutting knife is close to the cardboard, then replace the hydraulic rod to drive the replacement mounting plate to push the die-cutting knife to the cardboard, thereby die-cutting the cardboard. When the die-cutting knife needs to be replaced, the servo motor will drive the rotating rod to rotate the driving ring, and the driving ring will drive the switching plate to rotate the replacement hydraulic rod 180 degrees, thereby rotating the die-cutting knife to be replaced to the top and the bottom. The die-cutting knife can continue to die-cut the cardboard as the hydraulic rod and the mounting plate are replaced, and then the user removes the die-cutting knife to be replaced from the replacement mounting plate and replaces it with a new die-cutting knife.

[0031] In summary, the present invention has the following beneficial effects:

[0032] 1. By setting the positioning mechanism, the conveying component can cooperate with the limiting component to drive the cardboard to move, and the cardboard can be moved to the required processing position. The limiting component can cooperate with the adsorption component to temporarily limit the cardboard and increase the stability of the cardboard during die-cutting. The adsorption component can cooperate with the dust reduction component. When the cardboard is further twisted and die-cut to produce debris, the adsorption component can pump the debris into the dust reduction component for collection, thereby achieving the effect of auxiliary limiting the cardboard and recovering the debris at the same time;

[0033] 2. By setting up the die-cutting mechanism, the adjustment component can cooperate with the transmission component, and the adjustment component can drive the transmission component to move up and down, so that the transmission component can drive the switching component and the replacement component to approach the cardboard required for die-cutting processing. The transmission component can cooperate with the switching component to drive the switching component to rotate, so that the switching component can drive the replacement component to rotate. The switching component can cooperate with the replacement component. After the switching component adjusts the position of the replacement component of the tool to be replaced, the replacement component that can continue die-cutting processing will continue to die-cut the cardboard, and the replacement component that needs to replace the tool can directly replace the tool, which improves the efficiency of cardboard processing and increases the flexibility of tool replacement.

10. A method for using a die-cutting device for cardboard processing according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Auxiliary positioning and waste recycling: First, the positioning mechanism (1) is powered on and started, and then the cardboard to be processed is placed on the conveyor belt (1012). Then the electric rotating rod group (1011) will drive the conveyor belt (1012) to perform reciprocating motion and move the cardboard to the processing position of the die-cutting mechanism (2). Then the exhaust fan (1033) will extract the air at the adsorption plate (1023) to the water storage tank (1041) and let the air be discharged from the exhaust net (1043). The cardboard will be The vacuum generated by the pumped air causes the paperboard to be adsorbed on the adsorption plate (1023), and then the die-cutting mechanism (2) performs die-cutting on the paperboard. When the die-cutting generates debris, the debris is pumped into the water storage tank (1041) along the adsorption plate (1023), and then the heating plate (1042) heats the water in the water storage tank (1041), and the water generates steam that gradually accumulates in the water storage tank (1041). The debris comes into contact with the steam to increase its own mass, and then falls into the water storage tank (1041) and is collected by the water storage tank (1041); S2. Tool replacement: First, the die-cutting mechanism (2) is powered on and started, and then the hydraulic rod (2011) is adjusted to drive the adjusting top plate (2012) to move the transmission frame plate (221) downward until the die-cutting knife (2043) is close to the cardboard. After that, the hydraulic rod (2041) is replaced to drive the replacement mounting plate (2042) to push the die-cutting knife (2043) toward the cardboard, thereby performing die-cutting processing on the cardboard. When the die-cutting knife (2043) needs to be replaced, the servo motor (222) will drive the rotating rod (2023) to drive the ring When the hydraulic rod (2031) is rotated, the driving ring (2031) will drive the switching plate (2032) to rotate the replacement hydraulic rod (2041) 180 degrees, so that the die-cutting knife (2043) to be replaced is rotated to the upper side and rotated to the lower side. The die-cutting knife (2043) can continue to perform die-cutting processing on the cardboard along with the replacement hydraulic rod (2041) and the replacement mounting plate (2042). Then, the user can remove the die-cutting knife (2043) to be replaced from the replacement mounting plate (2042) and replace it with a new die-cutting knife (2043).
