DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a cardboard cutting knife.

[0025] The utility model provides Figure 1-3 The cardboard cutting knife shown includes a cutting plate 1, a limiting strip 5 is provided on the top of the cutting plate 1, and a cutting groove 3 is opened on the right side of the top of the cutting plate 1, a tool holder 2 is welded on the top of the cutting plate 1, a rotating motor 6 is installed on the side wall of the tool holder 2, a slide groove 13 is opened at the bottom end of the tool holder 2, a slide rod 17 and a slider 14 are built in the slide groove 13, a bidirectional cutter head 4 is arranged at the bottom end of the slider 14, a slide plate 8 passes through the right side of the cutting plate 1, a baffle plate 9 is fixed on the right side of the slide plate 8, a measuring strip 10 is fixed on the top of the cutting plate 1, a bidirectional cutter head 4 is arranged through the bottom end of the tool holder 2, and a driving mechanism in the tool holder 2 will push the bidirectional cutter head 4 to perform a reciprocating continuous cutting effect. During the placement of the cardboard, a continuous cutting effect can be formed on the cardboard, greatly improving the overall cutting efficiency of the cardboard.

[0026] In order to drive the bidirectional cutter head for reciprocating continuous cutting: Figure 1 and Figure 2As shown, the motor shaft of the rotating motor 6 passes through the interior of the slide groove 13, and a screw rod 16 is connected to the motor shaft of the rotating motor 6. A thread groove 15 is provided inside the slider 14. The screw rod 16 is adapted to the thread size of the thread groove 15 and constitutes a rotating mechanism. When the rotating motor 6 is working, it will drive the bidirectional cutter head 4 at the bottom end of the slider 14 to reciprocate, which will improve the efficiency of cardboard cutting during the cutting process.

[0027] In order to ensure the stability of the bidirectional cutting head: Figure 2 As shown, the two sides of the inner wall of the slide groove 13 are fixedly connected to the two sides of the outer wall of the slide rod 17, the slide rod 17 runs through the interior of the slider 14, and the slide rod 17 and the slider 14 constitute a sliding mechanism, the top of the bidirectional cutter head 4 is connected to the bottom end of the slider 14 through an external bolt, the slider 14 moves to drive the bidirectional cutter head 4 to move, and the slider 14 will slide on the slide rod 17 to ensure stability during cutting.

[0028] In order to ensure the sliding efficiency of the skateboard: Figure 3 As shown, a stabilizing plate 18 is fixed to the left side of the inner wall of the skateboard 8, and rollers 19 are installed at both ends of the stabilizing plate 18. The wheel wall of the roller 19 fits in the inner wall of the cutting board 1, and a pull rod 11 passes through the front side of the cutting board 1. The rollers 19 are arranged on both sides of the stabilizing plate 18. When the skateboard 8 slides inside the cutting board 1, it will be beneficial to ensure the lubrication of the skateboard 8 when it slides back and forth, facilitate the rapid adjustment of the skateboard 8, and facilitate the precise control of the length of the cardboard cutting to ensure the accuracy of the cutting.

[0029] In order to facilitate locking the slide: Figure 3 As shown, a pull head 12 is fixed to one end of the pull rod 11, and a stop block 22 is fixed to the other end of the pull rod 11, and the stop block 22 is made of rubber. A fixed spring sheet 20 is welded to the outer wall of the pull rod 11, and a spring 21 is sleeved on the outer wall of the pull rod 11, one end of the spring 21 is attached to the side wall of the fixed spring sheet 20, and the other end of the spring 21 is attached to the inner wall of the cutting plate 1. During the sliding adjustment of the slide plate 8, when the pull rod 11 is pulled, the stop block 22 will be elastically clamped on the side wall of the slide plate 8 by the spring 21, which is conducive to quickly fixing the slide plate 8. When the slide plate 8 determines the cutting distance, it is conducive to quickly locking the position of the slide plate 8 to ensure accurate cutting.

[0030] To control the operation of the device: Figure 1 As shown, the tool holder 2 is in a U shape, and a switch 7 is installed on the outer wall of the tool holder 2. The switch 7 is electrically connected to the rotating motor 6, and the switch 7 controls the rotating motor 6 to rotate forward and reverse.

[0031] When working, the cardboard is placed on the top of the cutting board 1, and the limit strip 5 on the top of the cutting board 1 forms a limit on the top of the cardboard. The cardboard passes between the knife holder 2 and the cutting board 1, and the pull head 12 drives the pull rod 11 to move. The pull rod 11 is forced to squeeze the spring 21 through the fixed spring sheet 20. At this time, the stop block 22 at the end of the pull rod 11 will be separated from the side wall of the slide 8. When the slide 8 moves left and right, it will drive the measuring strip 10 to control the cutting distance. When the position is reached, the pull rod 11 is loosened, and the spring 21 recovers its elasticity, so that the stop block 2 2 is squeezed and contacted with the side wall of the slide plate 8 again to ensure the locking of the slide plate 8, so as to achieve the required cutting length. The switch 7 drives the rotary motor 6 to work, and the rotary motor 6 will drive the screw rod 16 to rotate. The screw rod 16 will rotate in the thread groove 15 starting from the slider 14. At this time, the slider 14 will be driven to slide back and forth based on the slide rod 17, driving the bidirectional knife head 4 at the bottom end of the slider 14 to cut back and forth, and a continuous cutting effect can be achieved, which greatly improves the efficiency of the cardboard cutting process. The design is simple and more practical.
