The front side surface of the base frame three 5 is fixedly connected with the above-mentioned synchronous belt 15, and during the displacement of the synchronous belt 15, the base frame three 5 is driven to slide and displace on the linear guide rail 11, that is, the transverse cutting motor 13 is used for driving the base frame three 5 to perform linear sliding displacement on the base frame one 1.

The traverse mechanism 4 is mainly composed of a traverse fixed blade 41, a traverse movable blade 42, and a traverse movable blade holder 43. The transverse fixed blade 41 is a flat blade structure, and is arranged and molded along the length direction of the second base frame 2, and the blade extends out of the upper edge of the second base frame 2, is positioned at the rear edge of the notch of the paper feeding port 3, and is basically flush with or slightly lower than the rear edge of the lower guide plate.

The profile of the movable cross-cut blade holder 43 in the top view direction is substantially U-shaped, with the sealed edge being the rear side and the open edge being the front side. The middle part of the transverse cutting movable tool rest 43 corresponding to the length direction is hinged on a base frame III 5 through a connecting shaft assembly I45 consisting of a shaft lever, a bearing and the like, and is positioned at the oblique upper part of the transverse cutting fixed blade 41 and also positioned at the upper part of the paper feeding port 3; the transversely movable blade carrier 43 can swing in the forward and backward directions by a first connecting shaft assembly 45. The upper part of the front side of the transversely-cutting movable tool rest 43 is connected with a rear opposite structure (such as an auxiliary frame 52) through a pre-tightening spring 44, and the pre-tightening spring 44 pulls the upper part of the front side of the transversely-cutting movable tool rest 43 backwards, so that the lower part of the rear side of the transversely-cutting movable tool rest 43 has forward swinging potential energy; the two pre-tensioned springs 44 are preferably provided and are connected to the movable blade carrier 43 across the top of the front opening area.

The transversely-cutting movable blade 42 is of a circular blade structure, and can be of a regular circular structure or a polygonal structure. The transverse cutting movable blade 42 is movably assembled at the center of the rear side of the transverse cutting movable tool rest 43 in a circumferential rotating mode through a connecting shaft assembly 46 consisting of a shaft lever, a bearing and the like; the rotation path of the transversely movable blade 42 at the lower edge of the transversely movable blade holder 43 is ensured to extend downward along the rotation path of the blade edge of the transversely movable blade 42. The crosscut movable blade 42 is arranged on the rear side of the crosscut fixed blade 41 and is in close engagement with the crosscut fixed blade 41 at the paper feed port 3, under the pulling of the crosscut movable blade holder 43 by the pretensioned spring 44. The close fit means that the cutting edge of the transverse movable blade 42 and the cutting edge of the transverse fixed blade 41 form a close staggered fit, that is, the cutting edge of the transverse movable blade 42 and the cutting edge of the transverse fixed blade 41 are staggered fit at the paper feed port 3.

The cutting edges of the movable transverse cutting blade 42 and the fixed transverse cutting blade 41 are in staggered fit, and are preferably formed by an included angle alpha structure, and the maximum value of the included angle alpha is less than or equal to 5 degrees, such as 1 degree, 3 degrees or 5 degrees. Of course, instead of being formed with an angled configuration, a surface contact fit is also possible (i.e., an angle of substantially 0 °), which is clearly disadvantageous for autogenous cutting edge wear.

The slitting mechanism 6 is mainly composed of a slitting fixed blade 61, a slitting movable blade 62, and a slitting motor 65. The longitudinal cutting fixed blade 61 is a flat blade structure, which is fixedly connected to one side of the auxiliary frame 52 and corresponds to the transverse cutting mechanism 4, a blade point (i.e., a front end) of the longitudinal cutting fixed blade 61 extends toward the transverse cutting mechanism 4, and a blade edge height of the longitudinal cutting fixed blade 61 corresponds to a blade edge of the transverse cutting fixed blade 41.

The movable slitting blade 62 is also of a flat blade structure, the thickness of the movable slitting blade 62 is hinged to the rear end of the fixed slitting blade 61 through a connecting shaft assembly composed of a shaft lever, a bearing and the like, and the movable slitting blade 62 can rotate on the fixed slitting blade 61 around the connecting shaft assembly. The length of the slitting movable blade 62 corresponds to the length of the slitting fixed blade 61, i.e., the tip of the slitting movable blade 62 can extend to the cross cutting mechanism 4.

A longitudinal cutting motor 65 is installed on the other side of the auxiliary frame 52 and is positioned above the longitudinal cutting movable blade 62; the output shaft of the longitudinal cutting motor 65 extends toward the side of the longitudinal cutting movable blade 62. An eccentric driving wheel 64 is connected to an output shaft on the side of the longitudinal cutting movable blade 62, a connecting rod 63 is connected to the eccentric position of the eccentric driving wheel 64 through a connecting shaft assembly consisting of a shaft lever, a bearing and the like, namely, the upper end of the connecting rod 63 is hinged with the eccentric position of the eccentric driving wheel 64; the lower end of the connecting rod 63 is hinged to the middle front region of the movable slitting blade 62 through a connecting shaft assembly composed of a shaft lever, a bearing and the like. In this way, under the driving of the longitudinal cutting motor 65, the eccentric driving wheel 64 rotates circumferentially, and in the process, the connecting rod 63 is driven to move circumferentially eccentrically, so that the longitudinal cutting movable blade 62 running downwards is hinged with the longitudinal cutting fixed blade 61, and the longitudinal cutting movable blade 62 running upwards is opened with the longitudinal cutting fixed blade 61. The longitudinal cutting motor can be replaced by a suitable power device such as an electromagnet or an air cylinder.

The knife tip of the longitudinal cutting mechanism 6 corresponds to the position of the transverse cutting mechanism 4, and the knife tip keeps a knife back-off distance (about 1 mm) with the transverse cutting mechanism 4, so that the respective operation of the transverse cutting mechanism 4 and the longitudinal cutting mechanism 6 is not interfered with each other.

The automatic control system is mainly composed of an initial position detection sensor 12, a paper feed detection sensor 31, a paper edge detection sensor 53, an in-situ detection sensor 66, a transverse cutting motor 13, a longitudinal cutting motor 65 and a controller.

The initial position detection sensor 12 is arranged at one end of the base frame 1 to leave the paper inlet 3, so as to ensure that the base frame three 5 at the position does not influence the paper feeding at the paper inlet 3. The initial position detection sensor 12 is used for detecting whether the base frame three 5 is reset on the base frame one 1 close to the edge or not and feeding back a detected signal to the controller. The controller controls the paper feeding state at the paper feeding port 3 according to the reset signal detected by the initial position detection sensor 12, including that the current paper is conveyed to exit from the cutting position, and the subsequent paper enters into the cutting position.

A paper feed detection sensor 31 is arranged at the paper feed port 3, and serves to detect a paper feed start position of a current paper feed at the paper feed port 3 and feed back a detected signal to the controller. The controller obtains the current paper feeding depth according to the obtained current paper feeding starting position, the set paper feeding speed and the paper feeding time (usually, the paper feeding transmission motor is realized by a servo motor with higher control precision), and controls the paper feeding conveying state at the paper feeding port 3, including continuous paper feeding which does not reach the cutting size, paper feeding pause which reaches the cutting size and the like.

The sheet edge detection sensor 53 is arranged on the sub-frame 52 of the base frame three 5 to be substantially corresponding to the cutting edge of the cross cutting mechanism 4. The sheet edge detection sensor 53 serves to detect a transverse cutting edge of the incoming sheet at the sheet feed port 3, which is a start position of the transverse cutting, and feed back a detected signal to the controller. And the controller obtains the transverse cutting length of the current paper according to the obtained current paper edge starting position, the paper cutting speed (such as the pulse of the transverse cutting motor 13) and the paper cutting time, and when the real-time transverse cutting length of the current paper reaches the preset transverse cutting length, the transverse cutting is stopped.

The in-situ detection sensor 66 is arranged on the auxiliary frame 52 of the base frame III 5 and is positioned above the rear side of the slitting movable blade 62, and the slitting movable blade 62 is correspondingly matched with the in-situ detection sensor 66 when the slitting mechanism 6 is in an open state. The in-situ detection sensor 66 is used for detecting the opening reset state of the slitting mechanism 6 and feeding back a detection signal to the controller.

The controller controls the transverse cutting motor 13 to output power capable of driving the base frame three 5 to advance towards the transverse direction according to the currently obtained paper feeding depth and the paper feeding depth of the preset specification, namely, the base frame three 5 is driven to transversely cut and displace along the length directions of the base frame one 1 and the base frame two 2, and paper entering the paper feeding port 3 is cut. Of course, during the cross cutting, the conveyance is normally stopped at the paper feed port 3, and the paper feed port is kept stationary. In the transverse cutting process, the sheet edge detection sensor 53 detects the transversely cut sheet edge.

The controller controls the longitudinal cutting motor 65 to output power capable of driving the eccentric driving wheel 64 to rotate circumferentially according to the currently obtained transverse cutting length and the transverse cutting length with a preset specification, namely, the longitudinal cutting movable blade 62 is driven to hinge and open towards one side of the longitudinal cutting fixed blade 61. In the process, the in-situ detection sensor 65 detects the reset state of the longitudinal cutting movable blade 62, and the controller controls the longitudinal cutting motor 65 to stop according to the detection signal and controls the transverse cutting motor 13 to output power capable of driving the base frame III 5 to reset.
