Detailed Description

As shown in fig. 1, the roller type paperboard cutting machine comprises a machine base 1, a roller 2 and a paper pressing belt 6, wherein the paper pressing belt 6 is wound on a plurality of guide rollers 4 and acts on the roller 2 in a tightened state, and a paperboard feeding hole 7 and a paperboard discharging hole 8 are arranged between the paper pressing belt 6 and the roller 2; the machine base 1 is provided with a rotatable rotating shaft 3, the rotating shaft 3 is positioned on one side of the roller 2, the rotating shaft 3 is provided with a paperboard cutting line device 5, as shown in fig. 2, the paperboard cutting line device 5 comprises a longitudinal cutter 51, a transverse cutter 52 and a cutting line tool apron 50, the longitudinal cutter 51 and the transverse cutter 52 are both arranged on the cutting line tool apron 50, the cutting line tool apron 50 is arranged on the rotating shaft 3, and the rotating shaft 3 is in transmission connection with a cutting line power source for driving the rotating shaft 3 to rotate.

The working principle of the roller type paperboard cutting machine is as follows: a paper board enters from a paper board feed inlet 7 between the paper pressing belt 6 and the roller 2, is pressed on the roller 2 by the paper pressing belt 6 and rotates along with the roller 2; when the paper board moves to a set position, the cutting line power source drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the paper board cutting line device 5 to rotate, so that the longitudinal cutting knife 51 cuts a longitudinal cutting line A on the paper board, and the transverse cutting knife 52 cuts a transverse cutting line B on the paper board (as shown in figure 3); after the cutting line is finished, the paper board passes through a paper board discharge port 8 between the paper pressing belt 6 and the roller 2, and the cutting line is finished. Because the paper board is always attached to the roller surface of the roller 2, the conveying speed is quite consistent, and the line crossing error A1 of the paper board cutting line is much smaller than that of the conveying belt.

The utility model discloses a vertical cutting knife 51 is the semicircle sword, and horizontal cutting knife 52 is the flat sword, and the cutting edge one end of horizontal cutting knife 52 is close to mutually with the cutting edge of vertical cutting knife 51. It should be noted that the term "semicircular knife" does not refer to a semicircular knife, but refers to a knife that is not a full circle, as long as a notch that does not participate in cutting is properly reserved.

In order to cut the L-shaped cutting lines on the front and rear sides of the paperboard, the transverse cutters 52 are provided with two sets, one end of the cutting edge of one transverse cutter 52 is close to one end of the cutting edge of the longitudinal cutter 51, the transverse cutter 52 can cut the transverse cutting line B on the front side, one end of the cutting edge of the other transverse cutter 52 is close to the other end of the cutting edge of the longitudinal cutter 51, and the transverse cutter 52 can cut the transverse cutting line B on the rear side.

Equally, in order to cut out the L type secant on left and right sides on the cardboard, the utility model discloses install two cardboard secant devices 5 in pivot 3, two cardboard secant devices 5 bilateral symmetry set up. The two paperboard line cutting devices 5 cut lines simultaneously, so that the left side and the right side of the paperboard can be cut into L-shaped cut lines simultaneously.

Last worth mentioning is that, in order to detect the position of cardboard, one side of roller 2 is equipped with the color mark sensor, and the color mark sensor is located between cardboard feed inlet 7 and the pivot 3, and the color mark sensor is connected with the PLC electricity, and PLC control secant power supply work. When the color mark sensor detects the paperboard, the color mark sensor transmits a signal to the PLC, the PLC controls the output of the cutting line power source, and the cutting line power source drives the rotating shaft 3 to rotate, so that the cutting line work is realized.
