This utility model discloses a fully automatic cardboard cutting machine, comprising two supports and an adjustment device. A shearing plate is fixedly connected to the upper surface of the two supports. An adjustment device is provided on the surface of the shearing plate away from the supports. The adjustment device includes a rectangular groove located on the upper surface of the shearing plate. A first cover plate and a second cover plate are slidably connected to two inner walls of the rectangular groove, perpendicular to each other. The ends of the first and second cover plates are rotatably connected to each other. Two limiting plates are provided at the bottom of the rectangular groove. A T-shaped rod is connected to the upper surface of the limiting plates. A first pedal is fixedly connected to the end of the T-shaped rod away from the limiting plates, and a second pedal is rotatably connected to the end of the first pedal near the T-shaped rod.

The frame 1 provides support for the overall structure, ensuring stable operation of the equipment; the worktable 2 is fixedly mounted on the frame 1 and is used to place the cardboard to be cut; the blade holder 3 is slidably connected to the worktable 2 and can move horizontally. To accommodate different cutting lengths, the device is designed to accommodate various cutting needs. A mounting plate 41 is fixed to the blade holder 3 and is used to mount the cutting blade and the pressing mechanism 4. A transmission component connects the mounting plate 41 to the blade holder 3, driving the mounting plate 41 to move along the blade holder 3, thus adjusting the horizontal positioning of the cutting blade and the pressing mechanism 4. The cutting blade is mounted on the lower end of the mounting plate 41 and performs the cutting task. The pressing mechanism 4 is positioned in front of the cutting blade, ensuring the cardboard remains flat during cutting and preventing edge folding. A positioning plate is fixed to the worktable 2, limiting the outer perimeter of the cardboard to ensure cutting accuracy and efficiency. The working principle of the device is as follows: the transmission component drives the mounting plate 41 to slide on the blade holder 3, moving the cutting blade forward along the worktable 2 for cutting; simultaneously, the pressing mechanism 4 presses the cardboard to prevent displacement during cutting, ensuring a flat cut; the positioning plate is used to fix the edges of the cardboard, ensuring the accuracy and consistency of the cutting.

[0030] Please refer to the details. Figure 1 , Figure 2 and Figure 3The device includes a fixed plate 51 fixedly connected to the rear end face of the mounting plate 41, a rotary motor 521 fixedly connected to the fixed plate 51, a gear 52 connected to the output shaft of the rotary motor 521, and a gear shaft 53 fixedly mounted on the tool holder 3 and meshing with the gear 52. The gear shaft 53 is arranged along the length direction of the tool holder 3. The fixed plate 51 is fixedly connected to the rear end face of the mounting plate 41, serving to support and fix the rotary motor 521. The rotary motor 521 is fixed to the mounting plate 41 through the fixed plate 51 and is responsible for providing power to drive the movement of the entire device. The gear 52 is connected to the output shaft of the rotary motor 521, receives the power of the rotary motor 521 and converts it into rotational motion. The gear shaft 53 is fixedly mounted on the tool holder 3 and meshes with the gear 52, converting the rotational motion into linear motion, so that the tool holder 3 can move in the horizontal direction. In terms of working principle, when the rotary motor 521 is started, its output shaft drives the gear 52 to rotate. The gear 52 transmits power to the gear shaft 53 through meshing with the gear shaft 53, thereby causing the mounting plate 41 to move horizontally along the length of the tool holder 3, achieving precise horizontal movement.

[0031] Please refer to section 4 for details. The pressing mechanism 4 includes a fixed block 431 fixedly mounted on the front end face of the mounting plate 41, a pressure shaft 42 slidably connected to the fixed block 431, a pressure block 421 fixedly mounted on one end of the pressure shaft 42, a movable pressure plate 432 fixedly mounted on the other end of the pressure shaft 42 and slidably connected to the mounting plate 41, and a tension spring 44 disposed between the movable pressure plate 432 and the fixed block 431. One end of the tension spring 44 is fixedly connected to the movable pressure plate 432, and the other end of the tension spring 44 is fixedly connected to the upper end face of the fixed block 431. The fixed block 431 is fixedly mounted on... The front end of the mounting plate 41 provides guidance and support for the sliding of the pressure shaft 42. The pressure shaft 42 is slidably connected to the fixed block 431 and can move up and down within the fixed block 431. The pressure block 421 is fixedly installed at one end of the pressure shaft 42 and is used to directly press the cardboard. The movable pressure plate 432 is fixedly installed at the other end of the pressure shaft 42 and slidably connected to the mounting plate 41, and can move up and down. The tension spring 44 is installed between the movable pressure plate 432 and the fixed block 431, with one end fixedly connected to the movable pressure plate 432 and the other end fixedly connected to the fixed block 431, serving as a reset function. By pressing the movable pressure plate 432, the pressure shaft 42 drives the pressure block 421 to descend and press the cardboard. After cutting, the movable pressure plate 432 is released, and the tension spring 44 returns to its elasticity, pushing the pressure block 421 away from the cardboard, thus realizing the pressing and releasing operation of the cardboard. In this process, the use of a cylinder is avoided, which facilitates maintenance and reduces costs.

[0032] Please refer to the details.

The mounting plate 41 has a groove 411 that matches the slider 4321, with the groove 411 positioned along the height of the mounting plate 41. The movable pressure plate 432 achieves precise guidance in its movement direction through the slider 4321 fixed to one end of the mounting plate 41. The slider 4321 is embedded in the groove 411 on the mounting plate 41, which is also positioned along the height of the mounting plate 41. This sliding of the slider 4321 within the groove 411 ensures smooth, linear movement of the movable pressure plate 432, effectively preventing offset during movement. The working principle is as follows: when a force is applied to the movable pressure plate 432, the slider 4321 slides along the height direction within the groove 411, achieving the positioning and movement of the movable pressure plate 432, thus ensuring the reliability and accuracy of the pressure plate's movement.

The drive motor 631 is configured as a forward and reverse servo motor, used to drive the bidirectional lead screw 63 to rotate forward or reverse, thereby controlling the movement of the first moving seat 611 and the second moving seat 621 toward or away from each other.

[0034] Please refer to the details. Figure 1 and Figure 2To guide the mounting plate 41 during movement, the system includes a linear slide rail 31 arranged along the direction of the tool holder 3 and a slide block 311 fixedly mounted on the rear end face of the mounting plate 41 and adapted to the linear slide rail 31.

[0035] The implementation principle of the semi-automatic multi-functional cardboard cutting machine in this application embodiment is as follows: First, the cardboard is placed between the first positioning plate 61 and the second positioning plate 62. Then, the drive motor 631 is started, driving the bidirectional lead screw 63 to rotate forward or backward, thereby controlling the relative or opposite movement of the first moving seat 611 and the second moving seat 621. The first positioning plate 61 and the second positioning plate 62 move synchronously with the first moving seat 611 and the second moving seat 621, thereby facilitating the clamping of the outer periphery of the cardboard. When the rotary motor 521 is started, its output shaft... The gear 52 is driven to rotate, and the gear 52 transmits power to the gear shaft 53 through meshing with the gear shaft 53, thereby causing the mounting plate 41 to move horizontally along the length of the knife holder 3. When the mounting plate 41 slides on the knife holder 3, it drives the cutting blade to move forward along the worktable 2 to cut. By pressing the movable pressure plate 432, the pressure shaft 42 drives the pressure block 421 to descend to press the material. After the cutting is completed, the movable pressure plate 432 is released, and the tension spring 44 restores its elasticity and pushes the pressure block 421 away from the cardboard, thereby realizing the pressing and releasing operation of the cardboard and completing the cutting operation.
