Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, specifically a paper cutting and leveling device. Background Technology

[0002] Paper cutting and leveling is a crucial pre-processing step in cardboard box manufacturing. By cutting rolls of paper or large sheets of cardboard to specifications, mechanical flattening or heat-setting techniques are used to eliminate curling, warping, or wrinkles caused by fiber stress. This process is vital to cardboard box quality: a flat surface ensures accurate color registration during printing, preventing misalignment; it improves the penetration accuracy of the cutting tools during die-cutting, reducing burrs and dimensional errors; and it helps form regular edges during folding, preventing box deformation or seam cracking. Furthermore, leveling optimizes fiber alignment, enhancing the cardboard box's compressive strength and stacking stability, and reducing transportation damage. Through standardized processes, companies can improve product qualification rates, reduce raw material waste, and lay the foundation for efficient operation of automated equipment, ultimately achieving a finished product with an exquisite appearance and robust structure. However, in traditional processes, cutting and leveling require two separate machines, which is not only inefficient but also necessitates frequent manual material handling, limiting overall output speed. While existing technologies may already address these issues, this paper aims to provide an alternative or replacement solution. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a paper cutting and leveling device, comprising: a device base, several device legs, a paper sorting shell, and a rolling and leveling shell. The several device legs are respectively mounted on the device base. The paper sorting shell is mounted on the device base. The rolling and leveling shell is mounted on the device base. An alignment and pushing sorting structure is installed inside the paper sorting shell. A pneumatic leveling structure is installed inside the rolling and leveling shell. The alignment and pushing sorting structure includes: a sorting power shell, a sorting power motor, a transmission gearbox, symmetrical double-threaded screws, a pair of pushing sorting modules, a pair of electric telescopic rods, a paper displacement groove, and a pair of paper-moving sorting push blocks.

[0004] The finishing power housing is installed inside the paper finishing housing, the finishing power motor is installed inside the finishing power housing, the transmission gearbox is installed inside the paper finishing housing and is connected to the finishing power motor, the symmetrical double-threaded screw is installed inside the paper finishing housing and is inserted into the transmission gearbox, a pair of the pushing finishing modules are respectively fitted on the symmetrical double-threaded screw, a pair of the electric telescopic rods are respectively installed on the pair of the pushing finishing modules, a pair of the paper shifting finishing push blocks are respectively installed on the pair of the electric telescopic rods, and the paper finishing housing is provided with the paper displacement groove;

[0005] It should be noted that, as described above, the cut, barrelled raw paper is placed into the paper sorting housing. As it passes through the paper displacement groove below the housing, it is transported towards the flattening housing by an electric conveyor platform located below. During this slow transport, the motor inside the sorting power housing drives the transmission gearbox, causing the symmetrical double-threaded screw to rotate. This rotating screw, with its symmetrical threads, drives a pair of pushing sorting modules, bringing them closer together. Simultaneously, a pair of electric telescopic rods adjust their relative lengths, causing the paper-pushing sorting blocks to fit tightly against the sides of the cut paper, thus removing any irregularities. The aligned, pre-cut edges of the paper are tidied and pushed into a stack (the paper-pushing pusher has multiple small wavy lines; as it is repeatedly pushed against the sides of the paper and extended and retracted by the electric telescopic rod, it mimics the handling of paper by human hands. After repeated squeezing and pushing, multiple sheets of paper are neatly arranged). After being stacked and arranged, the paper is pushed by the electric conveyor to the flattening housing for flattening. The shock absorbers on the device's legs make the device more stable and quiet during operation, while the paper-pushing pusher's protective rubber pads prevent the messy paper from bending or deforming when it is squeezed and arranged by the pusher.

[0006] Preferably, the pneumatic leveling structure includes: a rolling power housing, a rolling power motor, a motor drive shaft, a roller body connecting shaft, a rolling roller body, a ceramic receiving roller, a load-bearing heating platform, several extending hydraulic push rods, and an inner mounting groove.

[0007] The rolling power housing is installed on the rolling leveling housing, the rolling power motor is installed inside the rolling power housing, the motor drive shaft is connected to the rolling power motor and is inserted into the rolling leveling housing, the roller body connecting shaft is connected to the motor drive shaft and is inserted into the rolling roller body, the rolling roller body is installed inside the rolling leveling housing, the ceramic receiving roller is installed on the bearing heating platform through a shaft, the device base is provided with an inner mounting groove, the extension hydraulic push rod is installed in the inner mounting groove, and several extension hydraulic push rods are respectively connected to the bearing heating platform;

[0008] It should be noted that, as described above, after the paper enters the rolling and leveling shell, the rolling power motor inside the rolling power shell rotates, which in turn causes the motor drive shaft to drive the roller body connecting shaft. The rotation of the roller body connecting shaft causes the rolling roller to rotate within the rolling and leveling shell. At the same time, the three extending hydraulic push rods in the mounting slot inside the seat extend upward, thereby pushing the bearing heating platform upward, which in turn causes the ceramic receiving roller to be lifted synchronously. As the ceramic receiving roller and the rolling roller come into contact with each other, the paper, which has been curled and bent for a long time, is squeezed and flattened after passing between the two. Meanwhile, the bearing heating platform generates heat by means of its built-in heating wire. Since the ceramic receiving roller is made of ceramic, it can conduct part of the heat from the bearing heating platform to the paper. The heated paper is easier to shape, making the paper after passing through the rolling and leveling shell flatter and smoother, thus participating in the subsequent paper box processing production.

[0009] Preferably, the device is equipped with shock absorbers on its support legs;

[0010] Preferably, the heating platform is equipped with a heating wire;

[0011] Preferably, an electric transport platform is provided on the base of the device;

[0012] Preferably, the paper-moving and sorting push block is provided with a paper protective pad.

[0013] Beneficial effects

[0014] This utility model provides a paper cutting and leveling device. It offers the following advantages compared to existing technologies: This device automates the processing of paper that has deformed due to prolonged curling after cutting, through an alignment and stacking structure. By using horizontal side-pushing and stacking technology, relatively scattered papers are aligned and stacked into neat stacks. Then, a pneumatic leveling structure applies controllable pressure and temperature to the stacked paper, utilizing both mechanical pressing and thermal setting to eliminate internal stress and restore the paper's flatness. This staged processing effectively solves the technical problems of warped and difficult-to-stack paper after cutting. The paper processed through these two steps not only has improved stacking neatness but also physically reshapes its fiber structure, providing reliable assurance for subsequent printing positioning, die-cutting accuracy, and forming effects in carton processing. This significantly improves the continuous operation capability and finished product qualification rate of automated production lines. Attached Figure Description

[0023] Example

[0024] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-5As shown, the paper cutting and leveling device includes: a device base 1, several device legs 2, a paper sorting shell 3, and a rolling and leveling shell 4. The several device legs 2 are respectively installed on the device base 1. The paper sorting shell 3 is installed on the device base 1. The rolling and leveling shell 4 is installed on the device base 1. An alignment and pushing sorting structure is installed inside the paper sorting shell 3. A pneumatic leveling structure is installed inside the rolling and leveling shell 4. The alignment and pushing sorting structure includes: a sorting power shell 5, a sorting power motor 6, a transmission gearbox 7, symmetrical double-threaded screws 8, a pair of pushing and sorting modules 9, and a pair of electric... The paper includes a telescopic rod 10, a paper displacement groove 11, and a pair of paper-pushing and sorting pushers 12; the sorting power housing 5 is installed inside the paper sorting housing 3, the sorting power motor 6 is installed inside the sorting power housing 5, the transmission gearbox 7 is installed inside the paper sorting housing 3 and connected to the sorting power motor 6, the symmetrical double-threaded screw 8 is installed inside the paper sorting housing 3 and inserted into the transmission gearbox 7, a pair of pushing and sorting modules 9 are respectively fitted onto the symmetrical double-threaded screw 8, and a pair of electric telescopic rods 10 are respectively installed on a pair of paper-pushing and sorting modules 12. On the push and sorting module 9, a pair of paper-pushing and sorting push blocks 12 are respectively installed on a pair of electric telescopic rods 10, and the paper sorting housing 3 is provided with a paper displacement groove 11; the pneumatic leveling structure includes: a rolling power housing 13, a rolling power motor 14, a motor drive shaft 15, a roller body connecting shaft 16, a rolling roller body 17, a ceramic receiving roller 18, a bearing heating platform 19, several extending hydraulic push rods 20, and an inner mounting groove 21; the rolling power housing 13 is installed on the rolling leveling housing 4, the rolling power motor 14 is installed inside the rolling power housing 13, and the motor drive shaft 15 is connected to the rolling power motor 14, and the motor drive shaft 15 is inserted into the rolling and leveling housing 4. The roller body connecting shaft 16 is connected to the motor drive shaft 15, and the roller body connecting shaft 16 is inserted into the rolling roller 17. The rolling roller 17 is installed inside the rolling and leveling housing 4. The ceramic receiving roller 18 is installed on the bearing heating platform 19 through a shaft. The device base 1 has an inner placement groove 21. The extension hydraulic push rod 20 is installed in the inner placement groove 21, and several extension hydraulic push rods 20 are respectively connected to the bearing heating platform 19.

[0025] According to the appendix Figure 1-5It is found that when the cut, barrelled raw paper is placed into the paper sorting housing 3, it is transported towards the rolling and flattening housing 4 by the electric conveyor platform located below the paper sorting housing 3 as it passes through the paper displacement groove 11. During the slow transport process, the sorting power motor 6 inside the sorting power housing 5 drives the transmission gearbox 7 to rotate, thereby causing the symmetrical double-threaded screw 8 to rotate. The rotating symmetrical double-threaded screw 8, relying on its pair of symmetrical threads, drives a pair of pushing sorting modules 9 to move, causing the pair of pushing sorting modules 9 to move closer to each other. At the same time, a pair of electric telescopic rods 10 are synchronously adjusted. The relative length of the paper is adjusted, thereby driving the paper-moving and sorting pusher 12 to fit tightly against the side of the cut paper, thus sorting and pushing the messy, misaligned edges of the already cut paper into a stack (the paper-moving and sorting pusher is equipped with multiple small wavy lines, which, through the continuous reciprocating pushing of the paper side and the reciprocating extension and contraction of the electric telescopic rod 10, mimic the sorting of paper by human hands. After repeated squeezing and moving, multiple sheets of paper will achieve a neat and uniform sorting operation). After being stacked and sorted, the paper is pushed by the electric transport table to the four sides of the flattening housing for flattening, while the device support legs... The shock absorber installed on the 2nd part makes the device more stable and quieter during operation. The paper protective pad on the paper-pushing and sorting pusher 12 prevents the messy paper from bending or deforming when it is squeezed and sorted by the paper-pushing and sorting pusher 12. After the paper enters the rolling and leveling housing 4, it drives the rolling power motor 14 in the rolling power housing 13 to rotate, which in turn causes the motor drive shaft 15 to drive the roller body connecting shaft 16. The rotation of the roller body connecting shaft 16 will drive the rolling roller 17 to rotate in the rolling and leveling housing 4. At the same time, the three extension hydraulic push rods 20 in the seat mounting groove 21 will extend upward, thereby... The heating platform 19 is pushed upward, which in turn causes the ceramic receiving roller 18 to be lifted simultaneously. As the ceramic receiving roller 18 and the rolling roller 17 come into contact with each other, the paper that has been curled and bent for a long time will be squeezed and flattened after passing between the two. At the same time, the heating platform 19 generates heat by means of its built-in heating wire, and the ceramic receiving roller 18 is made of ceramic, so it can conduct part of the heat from the heating platform 19 to the paper. The heated paper will be easier to shape, and the paper after passing through the rolling flat shell 4 will become flatter and smoother, so as to participate in the subsequent paper box processing production.
