Background

Some of the cardboard needs to be removed at the four corners so that the cardboard can be folded to form a box or a lid, and the cardboard needs to be grooved when folded. As shown in fig. 4, in the conventional paperboard process, a partial cutting line (shown as a dotted line in fig. 4) is firstly performed on one surface of a paperboard by a paperboard cutting machine, and then a groove is formed on the other surface of the paperboard along the cutting line by a paperboard grooving machine, so that four corners of the paperboard fall down due to the superposition of the cutting line and the grooving line, and the formed paperboard can be folded into a box or a cover. The existing paperboard cutting line machine comprises a conveying mechanism and a cutting line mechanism, wherein the cutting line mechanism comprises a transverse cutting line knife and a cutting line pressing roller, the transverse cutting line knife is a circular knife, a paperboard is conveyed by the conveying mechanism, the circular knife is driven by a power source to move upwards and lean against the cutting line pressing roller, the circular knife is matched with the cutting line pressing roller to cut a line (shown as a dotted line in figure 4) on the paperboard, and after a section of the line is cut, the power source drives the circular knife to move downwards. Then the cardboard is rotated by 90 degrees and placed on another cardboard cutting line machine for longitudinal cutting line. However, as shown in fig. 5, a circular knife is used, and a cutting line error L (4-5 mm) caused by a circular arc blade with a diameter of 4-5 mm is left on the paperboard, and the cutting line error L is unavoidable, and the error can cause the side edge of the paperboard to be easily torn, which affects the product quality.

Detailed Description

As shown in figure 1, the novel paperboard cutting line machine comprises a frame, wherein a conveying mechanism 1 and a cutting line mechanism are arranged on the frame, paperboards are conveyed through the conveying mechanism 1, and then the cutting line mechanism cuts the paperboards.

The line cutting mechanism comprises a transverse line cutting knife 5 and a line cutting press roller 2, the transverse line cutting knife 5 is positioned below the line cutting press roller 2, the line cutting press roller 2 actively rotates to drive the paper board to move forwards, and as shown in fig. 2 and 3, the transverse line cutting knife 5 is a semicircular knife. Here, 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 appropriately provided. The transverse thread cutting knife 5 is arranged on the rotating shaft 3, the rotating shaft 3 is in transmission connection with a power source (the power source is a servo motor) for driving the rotating shaft 3 to rotate, and the cutting edge of the transverse thread cutting knife 5 faces the conveying direction of the conveying mechanism 1. The rotating shaft 3 drives the transverse thread cutting knife 5 to rotate through the driving of a power source, namely the semicircular knife rotates.

The line cutting principle of the semicircular knife is as follows: as shown in fig. 6, when the paperboard is located between the cutting line pressing roller 2 and the semicircular knife (the linear speed of the two is the same), the partial arc blade of the semicircular knife starts to roll into the paperboard, and as the paperboard is conveyed forward, the front angle of the paperboard starts to cut a line until the blade end of the semicircular knife leaves the paperboard, and because the left side of the blade end of the semicircular knife is a notch and cannot cut into the paperboard, no cutting line error occurs on the paperboard, and the length of the partial arc blade of the semicircular knife is the distance of the cutting line; the notch of the semicircular knife is always opposite to the paper board along with the rotation of the semicircular knife, so that the semicircular knife does not cut a line any more; the paperboard is rolled into the other end of the cutting edge of the semicircular cutter along with the continuous rotation of the semicircular cutter, a line is cut at the rear angle of the paperboard along with the forward conveying of the paperboard, the line cutting error does not occur on the paperboard due to the fact that the right side of the end of the cutting edge of the semicircular cutter is a notch, and the circular arc cutting edge at the end of the semicircular cutter can cut the paperboard to the bottom. Therefore, when the cutting edge length of the semicircular cutter and the conveying line speed of the cutting line pressing roller are both determined (the conveying line speed of the cutting line pressing roller is the same as the moving speed of the paperboard), the cutting line distance can be controlled by controlling the rotating speed of the semicircular cutter (controlled by a motion controller). If the control is accurate, the line cutting mode can enable the line cutting distance to reach zero error, thereby obviously improving the quality of the paperboard line cutting.

As described in the background, transverse cutting of the cardboard requires longitudinal cutting, which is generally done on another cutting machine, which is obviously costly and inefficient. In order to overcome this kind of problem, the utility model discloses still install vertical secant sword 6 in pivot 3, as shown in fig. 3, vertical secant sword 6 is the flat sword, cutting edge one end of vertical secant sword 6 is close to with the cutting edge one end of horizontal secant sword 5 (the cutting edge of vertical secant sword 6 is mutually perpendicular at extending direction with the cutting edge of horizontal secant sword 5), through this kind of structure, when pivot 3 rotates, horizontal secant is accomplished to the cutting edge of horizontal secant sword 5, and vertical secant can be accomplished to the cutting edge of vertical secant sword 6, so a secant machine just can accomplish horizontal secant and vertical secant simultaneously, not only reduced equipment input cost, still show to have promoted the secant efficiency, and because two swords cut the line simultaneously, the secant precision is higher from this, the secant effect is better.

For the convenience of installing the transverse cutting knife 5 and the longitudinal cutting knife 6, the utility model discloses install blade holder 4 in pivot 3, the transverse cutting knife 5 and the longitudinal cutting knife 6 are all installed on blade holder 4. In order to adapt to the cutting lines of the paperboards with different specifications, the utility model discloses but still install blade holder 4 on pivot 3 with axial adjustment. The position of the line cutter can be adjusted by moving the cutter holder 4, so that the cutting lines of the paperboards with different specifications can be met.
