[0002] The cutting device used in carton production and processing is usually a kind of mechanical equipment integrated with advanced automation or semi-automation, designed to efficiently and accurately complete the cutting, trimming and other processes of cartons or cardboards. The core purpose of this type of device is to improve production efficiency, reduce costs, reduce material waste, and ensure cutting accuracy to meet the diverse needs of carton production.
[0003] Existing cutting machines are provided with a placement slot at the bottom of the cutting blade. The cutting blade cuts the bottom carton by moving downward until it extends into the placement slot to ensure that the cut is in place. However, when processing paper products of different cardboard thicknesses, the fixed size design of the placement slot limits its adaptability. When cutting thin cardboard, the blade may be too deep, which may easily damage the bottom or cause over-cutting. For thick cardboard, the groove may not be deep enough, and the cutting may not be in place, resulting in incomplete cutting. The pressure distribution of the blade on the cardboard is uneven, and thin cardboard is easily subjected to excessive force, resulting in unnecessary damage. Thick cardboard may not be cut deeply due to insufficient pressure, affecting the quality of the finished product.
[0004] Therefore, it is necessary to provide a new cutting device for carton production and processing to solve the above technical problems. Utility Model Content

[0006] The cutting device for carton production and processing provided by the utility model includes a cutting shell, a placement groove is provided on the cutting shell, a fixing frame is provided in the placement groove of the cutting shell, the tops of the two ends of the fixing frame extend to both sides and are provided with threaded holes, a plurality of fixing bolts threadedly connected to the placement groove of the cutting shell are provided on the threaded holes of the fixing frame, a cutting groove is provided in the fixing frame along the horizontal direction, a bearing bracket is fixedly connected to the inner wall of the cutting groove of the fixing frame, and the bearing bracket is arranged in sequence in a stepped manner from the top of the fixing frame to the bottom of the cutting groove.
[0007] Furthermore, two groups of mounting plates arranged in pairs are fixedly connected to the top of the cutting shell, and a sliding screw rod and a guide rod are respectively threadedly connected between the two groups of mounting plates. One end of the sliding screw rod extending out of the mounting plate is provided with a driving part fixedly connected to the top wall of the cutting shell, and the outer side walls of the sliding screw rod and the guide rod are provided with hydraulic parts.
[0008] Furthermore, the driving component is a servo motor, the servo motor is fixedly connected to the top wall of the cutting shell, and the output end of the servo motor is fixedly connected to the sliding screw.
[0009] Furthermore, the hydraulic parts include a hydraulic connecting frame, on which a threaded sleeve and a sliding sleeve are respectively fixed. The threaded sleeve is threadedly connected to the outer surface of the sliding screw, and the sliding sleeve is slidably connected to the outer surface of the guide rod. Two hydraulic cylinders are fixedly connected to the bottom of the hydraulic connecting frame, and the bottoms of the two hydraulic cylinders are fixedly connected to cutting parts.
[0010] Furthermore, the cutting member includes a lifting connection frame fixedly connected to the bottom of the two hydraulic cylinders, the bottom of the lifting connection frame is fixedly connected with a cutting blade, and the cutting blade is located above the supporting bracket.

DETAILED DESCRIPTION
[0020] The present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 , Figure 1 This is a schematic diagram of the overall structure of the cutting device for carton production and processing provided by the present invention; Figure 2 Schematic diagram of the cross-sectional structure of the cutting device for carton production and processing provided by the utility model Figure 1 ; Figure 3 Schematic diagram of the cross-sectional structure of the cutting device for carton production and processing provided by the utility model Figure 2 ; Figure 4 This is a structural diagram of the fixing frame provided by the utility model.
[0022] In the specific implementation process, Figures 1 to 4 As shown, the cutting device for carton production and processing provided by the present invention includes a cutting shell 1, a placement groove is provided on the cutting shell 1, a fixing frame 10 is provided in the placement groove of the cutting shell 1, the tops of both ends of the fixing frame 10 extend to both sides and are provided with threaded holes, a plurality of fixing bolts 11 are provided on the threaded holes of the fixing frame 10 that are threadedly connected to the placement groove of the cutting shell 1, a cutting groove 13 is provided in the fixing frame 10 in the horizontal direction, a supporting bracket 12 is fixedly connected to the inner wall of the cutting groove 13 of the fixing frame 10, and the supporting bracket 12 is arranged in a stepped manner from the top of the fixing frame 10 to the bottom of the cutting groove 13;
[0023] The placement slot on the cutting shell 1 is designed to be connected to the fixing frame 10 through fixing bolts 11 to ensure the stability of the structure and the convenience of adjustment. The threaded hole design on the fixing frame 10 makes the connection between the adjustment and the cutting shell bolts 1 tighter and easy to replace, simplifying maintenance time.
[0024] The stepped design of the supporting bracket 12 decreases in steps from the top of the fixed frame 10 to the bottom of the cutting groove 13. Whether it is thin cardboard or thick cardboard, it can find the appropriate cutting depth. When cutting thin cardboard, the blade only touches the bottom of the shallow groove to avoid damage to the bottom; when cutting thick cardboard, the blade penetrates the deeper groove to ensure a thorough cut and maintain the integrity of the cut. The stepped cutting groove 13 design greatly improves the adaptability of cardboard. From thin art paper to thick cardboard used for packaging, and even corrugated cardboard, it can be accurately cut by adjusting to the appropriate groove depth, avoiding incomplete cutting or damage caused by uneven thickness processing.

The outer walls of the sliding screw 4 and the guide rod 5 are provided with a hydraulic component. The driving member is a servo motor 2. The servo motor 2 is fixedly connected to the top wall of the cutting shell 1, and the output end of the servo motor 2 is fixedly connected to the sliding screw 4;
[0026] Two sets of mounting plates 3 are located on the top of the cutting shell 1. They are the basis for supporting other components, forming a frame to ensure overall stability and precise alignment to determine the position. The two sets of mounting plates 3 are connected by threaded sliding screws 4 and sliding connecting rods 5. The sliding screws 4 provide linear power transmission, and the guide rods 5 ensure the linearity of the movement. The two work together to ensure precise displacement. One end of the sliding screw 4 extends and is fixed to the top wall of the cutting shell 1 and is connected to the servo motor 2. The rotational power of the servo motor 2 is converted into linear motion through the sliding screw 4, thereby realizing precise control of the feed and retreat of the cutting parts.

The design of the lifting connecting frame 8 ensures the stable rise and fall and retraction of the cutting blade 9, and is prepared for continuous operation. The cutting blade 9 is located above the supporting bracket 12, ensuring that the cutting blade 9 can accurately align with the cardboard or other materials for cutting when it descends, so that it will not deviate.
[0031] A connecting rod 15 is rotatably connected to one side of the top of the cutting housing 1. An operating screen 16 is rotatably connected to the end of the connecting rod 15 away from the cutting housing 1. A material guide rack 14 is fixedly connected to one side of the outer surface of the cutting housing 1.
