In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0025] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description.

[0028] An integrated three-roll head cutting device of the present utility model, as Figure 1 shown, includes a frame 1, and a pinch roll lifting mechanism 2, a leveling roll lifting mechanism 3 and a head cutting shear mechanism 4 are sequentially arranged on the frame 1 along the running direction of the sheet.

[0029] As Figure 2 shown, the pinch roll lifting mechanism 2 includes a liftable and movable pinch roll 21. Two pinch rolls 21 are arranged vertically, and a pinch space is formed between the two pinch rolls 21 for clamping and driving the sheet to advance. Specifically, both the left and right sides of the pinch roll 21 are arranged on the frame 1 through pinch sliders 22, and the pinch sliders 22 can drive the pinch roll 21 to perform liftable movement under the action of a cylinder 23. A gear 24 and a rack 25 are also provided on the left and right pinch sliders 22, and a pinch synchronizing shaft 26 is arranged between the left and right gears 24 for realizing synchronous lifting of the left and right pinch sliders 22. Further, the pressures of the left and right cylinders 23 are respectively controlled by a pressure regulating valve to ensure that the sheet does not deviate.

[0030] As Figure 3As shown in the figure, the leveling roll lifting mechanism 3 includes a leveling roll 31 that can be lifted and moved. Three leveling rolls 31 are provided and arranged in a triangle for bending the plate head and initially leveling the sheet material. Specifically, both the left and right sides of the leveling roll 31 are arranged on the frame 1 through leveling sliders 32. The leveling sliders 32 are connected to a lift 33, and the lift 33 is connected to a variable frequency motor 34. A leveling synchronizing shaft 35 is arranged between the left and right lifts 33 to achieve synchronous lifting and lowering of the left and right leveling sliders 32. Further, the encoder controls the variable frequency motor 34 to achieve precise lifting and lowering of the leveling roll 31.
