Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a corrugated cardboard cutting machine. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall corrugated paperboard and double-wall corrugated paperboard. It has the advantages of low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. During transportation, corrugated paper can protect the products inside the packaging.

[0003] Currently, patent document No. 202321742918.4 discloses a corrugated paper cutting device, which includes a pushing assembly and a cutting assembly. The pushing assembly includes a processing table, a driving component, a pushing plate, an adjusting component, and a limiting plate. The driving component is located on the side of the processing table, and the end of the pushing plate is fixedly connected to the driving component. The adjusting component is located on one side of the pushing plate. The cutting assembly includes a fixing frame, a cylinder, a groove plate, an elastic clamping component, and a cutting blade. The fixing frame is fixedly connected to the top of the processing table. However, this device still has some shortcomings in use. For example, the device uses a spring and an L-shaped pressure plate to assist in pressing the corrugated paper to ensure the cutting quality at the cut. In actual use, the thickness of the corrugated paper to be cut varies. This results in the L-shaped pressure plate applying too much pressure to thicker corrugated paper, which may damage the paper. Conversely, for thinner corrugated paper, the pressure may be insufficient, making effective pressing impossible. Utility Model Content

[0017] like Figures 1 to 4As shown, the corrugated cardboard cutting machine of this embodiment includes a base plate 1, a fixed frame 2 mounted on the upper end of the base plate 1, a hydraulic rod 3 mounted on the upper end of the fixed frame 2, and a mounting block 4 mounted on the output end of the hydraulic rod 3. The hydraulic rod 3 serves as a power source, driving the mounting block 4 to achieve vertical lifting and lowering. A mounting groove 5 is provided at the lower end of the mounting block 4, and a cutting blade 6 is installed inside the mounting groove 5. The mounting groove 5 at the lower end of the mounting block 4 is used for quick replacement or fixing of the cutting blade 6 to adapt to different cutting needs. The cutting blade 6 is made of high-hardness material to ensure sharp cutting edges and improve cutting efficiency. Adjustment grooves 7 are provided at both ends of the mounting block 4, and mounting plates 8 are installed inside both adjustment grooves 7. An adjustment screw 9 is installed between the mounting plate 8 and the adjustment groove 7. An adjusting block 10 is threaded onto the surface of the adjusting screw 9. A connecting plate 11 is installed at one end of the adjusting block 10, and a fixing plate 12 is installed at the lower end of the connecting plate 11. A pressure plate 13 is movably installed below the fixing plate 12. The vertical position of the pressure plate 13 is adjusted within the adjusting groove 7 by adjusting the adjusting screw 9 and the adjusting block 10 to accommodate the fixing requirements of corrugated cardboard of different thicknesses. The pressure plate 13 is connected to the fixing plate 12 by a spring spring 24 to provide flexible pressure, prevent the cardboard from sliding during the cutting process, and avoid damaging the surface of the cardboard. This allows for easy adjustment of the pressing pressure of the pressure plate 13 according to the thickness of the corrugated paper being cut. A drive assembly is installed on the upper end of both adjusting screws 9 to achieve synchronous rotation of the two adjusting screws 9.

[0018] Specifically, the drive assembly includes a rotating rod 1401, a first conical wheel 1402, a second conical wheel 1403, and a handle 1404. An installation cavity 25 is provided inside the mounting block 4 above the adjusting groove 7. The rotating rod 1401 is rotatably mounted inside the mounting cavity 25. Two first conical wheels 1402 are mounted on the surface of the rotating rod 1401. A second conical wheel 1403 is mounted on the upper end of each of the two adjusting screws 9. The first conical wheel 1402 and the second conical wheel 1403 mesh with each other. Both ends of the rotating rod 1401 extend to the outside of the mounting block 4, and handles 1404 are mounted on both ends of the rotating rod 1401. The two adjusting screws 9 are linked by the rotating rod 1401. The meshing transmission of the first conical wheel 1402 and the second conical wheel 1403 enables the simultaneous adjustment of the positions of the two pressure plates 13 by operating a single handle 1404, ensuring that the two pressure plates 13 are at the same height.

[0019] Furthermore, guide rods 15 are installed on both the front and rear ends of the upper end of the fixed plate 12, and guide plates 16 are installed on the inner wall of the adjustment groove 7 on one side of the guide rods 15. The guide rods 15 are slidably installed inside the guide plates 16. The guide rods 15 installed on the upper end of the fixed plate 12 cooperate with the guide plates 16 on the inner wall of the adjustment groove 7 to form a guiding mechanism, which ensures the linear motion accuracy of the fixed plate 12 during the lifting process.

[0020] Furthermore, an electric push rod 17 is installed at the bottom of the base plate 1, and a moving groove 18 is provided in the middle of the upper end of the base plate 1. A push plate 19 is installed at the output end of the electric push rod 17 and inside the moving groove 18. The electric push rod 17 and the push plate 19 installed at the bottom of the base plate 1 achieve automatic feeding. The electric push rod 17 can accurately control the position of the push plate 19 in the moving groove 18, thereby realizing automatic feeding of corrugated cardboard.

[0021] Furthermore, a material drop trough 20 is provided on the upper end of the bottom plate 1 on one side of the cutting blade 6. A material drop plate 21 is installed at an incline inside the material drop trough 20, and a collection box 22 is placed below the material drop plate 21. The material drop trough 20 on one side of the cutting blade 6 and the inclined material drop plate 21 form a waste collection channel. The waste generated during the cutting process can slide down the material drop plate 21 into the collection box 22, realizing the centralized collection and cleaning of waste, which is convenient for the later utilization of waste.

[0022] Furthermore, guide rods 23 are installed at both the front and rear of the upper end of the pressure plate 13. The upper ends of the guide rods 23 pass through the fixing plate 12 through through holes. A spring spring 24 is installed between the pressure plate 13 and the fixing plate 12 and on the surface of the guide rod 23. The guide rods 23 installed at the upper end of the pressure plate 13 cooperate with the through holes on the fixing plate 12 to guide the lifting and lowering movement of the pressure plate 13. At the same time, the spring spring 24 installed on the surface of the guide rod 23 provides elastic pressure to the pressure plate 13, enabling it to fit tightly against the surface of the corrugated cardboard. This design ensures the stability of the cardboard during the cutting process and avoids damage to the cardboard caused by excessive clamping force.

[0023] The method of use in this embodiment is as follows: When this corrugated cardboard cutter is working, firstly, according to the thickness of the corrugated cardboard, the vertical position of the pressure plate 13 is adjusted by the drive assembly. The operator turns the handle 1404, which drives the rotating rod 1401 to rotate. The conical wheel 1402 on the rotating rod 1401 rotates accordingly. Since the conical wheel 1402 meshes with the conical wheel 1403 at the upper end of the adjusting screw 9, the adjusting screw 9 is driven to rotate. The adjusting block 10 on the surface of the adjusting screw 9 moves up and down with the rotation of the adjusting screw 9. The connecting plate 11 drives the fixed plate 12 and the pressure plate 13 to move. The guide rod 15 slides in the guide plate 16 to ensure the linear motion accuracy of the fixed plate 12, thereby adjusting the pressure plate 13 to a suitable height so that it can adapt to the fixing requirements of corrugated cardboard of different thicknesses. The electric push rod 17 works to push the push plate 19 to move in the moving groove 18, pushing the corrugated cardboard to the appropriate position. Then, the hydraulic rod 3 is activated, acting as a power source to drive the mounting block 4 to achieve vertical lifting and lowering. The cutting blade 6 at the lower end of the mounting block 4 then descends to cut the corrugated cardboard. During the cutting process, the pressure plate 13, under the action of the elastic spring 24, moves through the through hole on the fixed plate 12 via the guide rod 23, providing flexible pressure to the corrugated cardboard, preventing the cardboard from sliding and avoiding damage to the cardboard surface. The waste generated during cutting slides down the inclined drop plate 21 through the drop chute 20 into the collection box 22, achieving centralized collection of waste.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
