Description

Technical Field

[0001] The utility model relates to the technical field of paper bottom pull strip processing, in particular to a fixed-length cutting device for processing paper bottom pull strips. Background Art

[0002] Paper tie bars are long, flexible, and durable auxiliary tools or connectors made of paper. They are primarily used to connect or secure various items, particularly in applications like tenders and packaging. A fixed-length cutting device is required to cut the tie bars to the desired length.

[0003] For example, the Chinese patent "A cutting device for paper product manufacturing" with announcement number CN217802040U includes a cutting device body and a placement platform. The placement platform is fixedly connected to the right side of the cutting device body, and a mounting groove is provided on the left side of the top of the placement platform. A fixing rod is fixedly connected to the top of the inside of the mounting groove, and an inclined plate is movably connected to the surface of the fixing rod. A transmission mechanism is embedded on the right side of the bottom of the mounting groove. A movable groove is provided on the right side of the placement platform, and a connecting groove is provided on the left side of the inner wall of the movable groove. The movable groove is connected to the mounting groove through the connecting groove, and a collection box is movably connected inside the movable groove.

[0004] Although the above-mentioned existing technology can realize the cutting of paper bottom pull strips, in actual use, on the one hand, the paper bottom pull strips are difficult to adjust to the appropriate length. Usually, the paper bottom pull strips are cut with manual assistance, and the cutting length is the length of the paper bottom pull strips pushed by the operator, thereby reducing the accuracy of the length of the paper bottom pull strips. On the other hand, the cutting of paper bottom pull strips is not convenient enough. After a section of paper bottom pull strips is cut, the paper bottom pull strips need to be manually adjusted to the next cutting state, thereby increasing the workload of the operator. Therefore, it does not meet the existing needs. For this reason, we propose a fixed-length cutting device for paper bottom pull strip processing. Utility Model Content

[0014] 1. The utility model can adjust the moving length of the paper bottom pull strip through the driving motor and the pulley. When the paper bottom pull strip is cut, the pulley has been adjusted to a suitable position and the paper bottom pull strip is fixed between the pulleys. At this time, the driving motor is turned on again, so that the output shaft of the driving motor drives the fixed rod to rotate, and the driving gear located outside the fixed rod above the mounting plate drives the transmission gear meshing with it to rotate, and the transmission gear drives the pulley located below the mounting plate to rotate, and the friction between the two pulleys and the paper bottom pull strip drives the paper bottom pull strip to move until the paper bottom pull strip is moved to a suitable length and cut, thereby improving the accuracy of fixed-length cutting of the paper bottom pull strip.

[0015] 2. The utility model uses the first hydraulic telescopic device and the movable seat to pull out the paper bottom pull strip that needs to be cut from the side of the cutting knife. When the cutting of a section of the paper bottom pull strip is completed, the first hydraulic telescopic device is turned on and the pulley is kept in a rotating state. The extension of the telescopic end of the first hydraulic telescopic device pushes the movable seat to move in the slide groove toward the center position of the processing table until the mounting plate and the pulley on the movable seat are moved to a suitable position. At this time, the pulley on the movable seat clamps the paper bottom pull strip that has been extended for a distance, and the first hydraulic telescopic device is turned on again to retract the telescopic end of the first hydraulic telescopic device and drive the movable seat to return to its original position. At this time, the drive motor is turned on again and the pulley drives the paper bottom pull strip to move to a suitable length, thereby reducing the workload of the operator.

[0016] 3. The utility model can adjust the distance between the mounting plates through the screw rod and the servo motor. Before the cutting operation, the mounting plate is first adjusted according to the width of the paper bottom pull strip. At this time, the servo motor is turned on, so that the output shaft of the servo motor drives the screw rod to rotate, and the mounting plate is driven to slide in the limit groove through the thread on the outside of the screw rod. The pulley fixedly connected to it is driven by the mounting plate to move toward the center position of the first fixed seat until the pulley is moved to a suitable position. At this time, the paper bottom pull strip is passed through the gap between the pulleys, and the paper bottom pull strip is clamped and fixed by the pulleys at both ends, thereby improving the adaptability of the pulley to paper bottom pull strips of different sizes.
