[0020] Please see Figure 1-4This utility model provides a technical solution: a cutting device for food packaging box production, including a support rod 1. The support rod 1 is an elastic element with gas and liquid as working media, consisting of a pressure pipe, a piston, a piston rod, and several connecting parts. It is filled with high-pressure nitrogen. Due to a through hole inside the piston, the gas pressure at both ends of the piston is equal, but the cross-sectional areas on both sides of the piston are different. One end is connected to the piston rod while the other end is not. Under the action of gas pressure, a pressure is generated towards the side with the smaller cross-sectional area, i.e., the elastic force of the support rod 1. The magnitude of the elastic force can be set by setting different nitrogen pressures or piston rods of different diameters, thereby adjusting the height of the worktable assembly. A worktable assembly 6 is installed at the top of the support rod 1, and a connecting rod is fixedly connected to one side of the support rod 1. The system is equipped with slide rails 2 and four support rods 1. The tops of the four support rods 1 are connected to the four corners of the bottom surface of the platform 601 by bolts. The four support rods 1 are arranged in pairs, and connecting rods are welded to opposite sides of the two pairs of support rods 1. The two connecting rods are arranged opposite each other. There are two slide rails 2, and the two ends of the two slide rails 2 are welded to the two connecting rods respectively. A support frame 4 is slidably fitted on the top surface of the slide rail 2. A hydraulic rod 3 is installed on one side of the support frame 4. A saw blade 5 is installed on the top of the support frame 4. A slider is slidably fitted on the slide rail 2. The slide rail 2 is slidably connected to the bottom surface of the support frame 4 through the slider. One end of the hydraulic rod 3 is connected to the top surface of one of the connecting rods by bolts. The hydraulic rod 3 is located between the two slide rails 2. The hydraulic rod 3 can be a Rexroth HKS02-25 / 1 model. 6-200, the hydraulic rod 3 is connected to an external hydraulic station, and its extension and retraction are controlled by an electromagnetic reversing valve. A vertical plate is welded to the top of the support frame 4, and mounting holes are provided on the vertical plate. A driver is installed at one end of the saw blade 5, and a drive shaft is located on one side of the driver. The drive shaft passes through the mounting holes and is rotatably connected to the saw blade 5. The driver can be a Panasonic MINASA6100W servo motor, connected to the drive shaft via a reducer, allowing adjustment of the saw blade 5's speed. The workbench assembly 6 includes a table plate 601, with a through groove 602 on the top surface of the table plate 601. Sliding grooves 603 are provided on both sides of the through groove 602. A limit assembly 7 is installed on the top surface of the table plate 601, including a baffle 701. An adjustment groove 702 is provided on one side of the baffle 701, and an electric push rod 7 is installed on the upper part of the baffle 701. 03. The electric push rod 703 can be a DEWINDDT06-150 model. It uses a 24V DC motor and worm gear transmission to drive the connecting frame 704 and the positioning rod 705 to vertically lift and lower to the designated position. The connecting frame 704 is installed at the top of the electric push rod 703, and the positioning rod 705 is threadedly connected to the connecting frame 704. A plate extends upward from one side of the baffle 701, with two through holes. One end of the electric push rod 703 passes through these through holes and is installed on the baffle 701. The electric push rod 703 is threadedly connected to the positioning rod 705 via the connecting frame 704. The electric push rod 703 and the positioning rod 705 are combined in a "T" shape. The bottom end of the positioning rod 705 is located above the platform 601. A hydraulic cylinder 8 is installed on the other side of the top surface of the platform 601.Hydraulic cylinder 8 can be a double-acting hydraulic cylinder, sharing a hydraulic station with hydraulic rod 3. It controls the horizontal movement of push plate 9 via a separate solenoid directional valve. Push plate 9 is installed at one end of hydraulic cylinder 8. The upper part of saw blade 5 extends through slot 602 and is positioned above table 601. Two limiting components 7 are located on either side of the opening of slot 602. One baffle 701 has an extension block at its bottom, which slides within slide groove 603. Hydraulic cylinder 8 is bolted to the top surface of table 601 near the baffle 701 with the extension block. Push plate 9 abuts against the outer wall of baffle 701 on one side. A protective cover is welded to the outside of the other baffle 701. One end of the protective cover is open, and its position matches the adjusting groove 702. Slot 602 extends to the bottom of the protective cover. The open saw blade 5 can be moved along slide rail 2 by hydraulic rod 3, thus moving into the protective cover.

[0021] First, connect an external power source to the electrical equipment in this device. Place the device in the designated working position. Place the food packaging box material on the top surface of the table 601. Adjust the height of the workbench assembly 6 to a suitable position using the support rod 1. The electric push rod 703 drives the positioning rod 705 to descend vertically until it touches the material surface at the bottom. The hydraulic cylinder 8 pushes the push plate 9 to move horizontally, pressing the material between the two baffles 701. The servo motor starts and drives the saw blade 5 to rotate. The hydraulic rod 3 controls the support frame 4 to slide along the slide rail 2, driving the saw blade 5 to move through the through groove 602 into the protective cover. Cut the material according to the set path. After cutting, the hydraulic rod 3 drives the saw blade 5 to return to the initial position. The electric push rod 703 lifts the positioning rod 705, and the hydraulic cylinder 8 drives the push plate 9 to reset, allowing the cut packaging box material to be removed.
