Description

Technical Field

[0001] This application relates to the technical field of decorative paper cutting, and in particular to a multi-blade cutting device and a decorative paper cutting process. Background Technology

[0002] In the current decorative paper processing industry, the cutting of decorative paper is undoubtedly a crucial step. For a long time, the main cutting method has been to use sharp straight or circular blades, applying pressure to force the blade's edge into the decorative paper. As the blade moves along the predetermined cutting line, the shearing force of the blade cuts the decorative paper.

[0003] However, existing technologies have significant drawbacks. During the cutting process, the decorative paper tends to shift, causing the cutting tool to easily deviate from the original cutting line. This significantly reduces cutting accuracy, making it difficult to meet the high-precision processing requirements of decorative paper. Furthermore, the deviation of the cutting tool from the cutting line results in uneven cut edges, greatly affecting the aesthetics of the decorative paper and its subsequent performance.

[0004] Therefore, improvements and innovations in decorative paper cutting technology must focus on solving the problems of poor precision and uneven edges caused by decorative paper misalignment, thereby improving the quality and reliability of decorative paper cutting and better meeting the ever-evolving needs of the decoration industry. Summary of the Invention

[0005] The purpose of this application is to provide a multi-blade slitting device and a decorative paper slitting process to improve the slitting accuracy of decorative paper.

[0006] The multi-blade slitting device provided in this application adopts the following technical solution: it includes a frame, guide rollers rotatably connected to both ends of the frame, a paper feeding mechanism disposed at one end of the frame, a paper taking mechanism disposed at the other end of the frame, a slitting mechanism disposed between the paper feeding mechanism and the paper taking mechanism, a first adjusting mechanism disposed between the slitting mechanism and the paper feeding mechanism, and a second adjusting mechanism for adjusting the tilt angle of the paper feeding mechanism. Decorative paper is drawn out from the paper feeding mechanism, passes around the guide rollers to change its traction direction, and passes through the first adjusting mechanism. The first adjusting mechanism adjusts the position of the decorative paper before it enters the slitting mechanism. During the adjustment of the decorative paper position, the second adjusting mechanism assists the first adjusting mechanism in adjusting the force of the decorative paper. The decorative paper enters the slitting mechanism and is slitted along the cutting line. The slitted decorative paper is then wound up by the paper taking mechanism.

[0007] By adopting the above technical solution, during the decorative paper cutting process, the decorative paper will often shift left and right. The first adjustment mechanism can adjust the position of the decorative paper before entering the cutting mechanism to ensure that the paper can accurately enter the cutting mechanism, thereby improving the cutting accuracy and quality. During the paper position adjustment process, the tension changes. The second adjustment mechanism adjusts the tilt angle of the paper feeding mechanism to change the tension of the decorative paper, so that the paper maintains appropriate tension during the transmission process, avoiding the paper being too loose or too tight, which would affect the cutting effect.

[0008] Preferably, the cutting mechanism includes mounting blocks fixedly connected to both sides of the frame, a rotating rod rotatably connected to the mounting blocks, several blades movable along the rotating rod, blades mounted on the blades, a pressing block abutting against the surface of the decorative paper, and an auxiliary module fixedly connected to the mounting blocks. The blade end is embedded in the auxiliary module, and the part of the pressing block abutting against the surface of the decorative paper is located between the blade end and the blade end.

[0009] By adopting the above technical solution, during the decorative paper slitting process, the decorative paper is conveyed from the paper feeding mechanism, and after the position is adjusted by the first adjustment mechanism, it enters the slitting mechanism; the knife bar and blade on the rotating rod have been adjusted to the appropriate position according to the slitting requirements, and the pressing block abuts against its surface to ensure the stability of the paper position; the decorative paper moves relative to the blade, and the blade slits the decorative paper.

[0010] Preferably, the auxiliary module includes a housing fixedly connected to the mounting block, and a support component and a detection component disposed on the housing. The support component includes a groove disposed on the top surface of the housing, a support block slidably connected to the groove, and a limiting groove opened on the top of the support block. The width of the limiting groove is 1-1.03 times the thickness of the blade, and the blade is embedded in the limiting groove.

[0011] By adopting the above technical solution, the blade needs to maintain a stable position and angle during the decorative paper slitting process to ensure slitting accuracy and quality. The support component, through the sliding of the slider within the groove, can be adjusted according to the blade's position, ensuring the blade is always embedded within the limiting groove. When the blade is subjected to a reaction force from the decorative paper, the limiting groove provides support, preventing the blade from bending or deforming. Simultaneously, the cooperation between the slider and the groove allows the blade to adjust as the decorative paper moves during slitting, accommodating cuts of different sizes.

[0012] Preferably, the detection component includes a groove formed on the top surface of the housing, a balance rod rotatably connected to the side wall of the groove, a gyroscope fixedly connected to the rotation point of the balance rod, force plates set at both ends of the balance rod, and a clamping plate fixed to the surface of the housing by bolts. The two ends of the balance rod are bent towards the top surface of the housing, and both ends of the balance rod are fixedly connected to sliders. A sliding rod passes through the slider, and the position of the sliding rod in the slider can be fixed by bolts. The end of the sliding rod is fixedly connected to the force plate, and a semi-cylinder is fixedly connected to the clamping plate. The semi-cylinder is located in the groove.

[0013] By adopting the above technical solution, during the decorative paper cutting process, when the paper passes through the detection component, the semi-cylinder causes the paper to form an arc shape, enhancing the force on the side of the paper. When the paper deviates, the side of the paper pushes the force plate, which in turn moves the slider via a slide bar. The slider then causes the balance bar to tilt. The gyroscope at the rotation point of the balance bar detects the tilt angle and direction of the balance bar in real time, thereby determining the extent of paper deviation.

[0014] Preferably, the first adjustment mechanism includes a fixed block fixedly connected to both sides of the frame, a first air plate with an external air pump, a second air plate with an external air pump, and a lead screw assembly disposed on the fixed block. The first air plate and the second air plate are both fixedly connected to the fixed block, and the moving end of the lead screw assembly is fixedly connected to the first air plate. The first air plate and the second air plate are respectively disposed on both sides of the decorative paper, and the fixed block is provided with a first motor that drives the lead screw assembly.

[0015] By adopting the above technical solution, when the decorative paper shifts, the second air plate can quickly blow the decorative paper towards the first air plate by increasing air pressure. The first air plate then adsorbs the decorative paper and adjusts it to the appropriate position via the lead screw assembly. This pneumatic adjustment method has a fast response speed, enabling it to respond to paper shifts in a short time and prevent the paper from continuing to deviate from the correct position, thereby reducing slitting errors that may be caused by paper shifts. Since the second air plate blows the decorative paper towards the first air plate through airflow, this non-contact adjustment method will not cause direct mechanical damage to the paper.

[0016] Preferably, the second adjustment mechanism includes a rotating frame fixedly connected to the mounting frame, a rotating frame rotatably connected to the mounting frame, and a second motor that drives the rotating frame to rotate. The rotating frame is connected to the paper feeding mechanism. The second motor drives the rotating frame to rotate through gear transmission. Several tension springs are provided between the rotating frame and the mounting frame. The tension springs force the two ends of the rotating frame to maintain balance. The top of the rotating frame is fixedly connected to the support plate.

[0017] By adopting the above technical solution, during the decorative paper cutting process, the second adjustment mechanism adjusts the tilt angle of the paper feeding mechanism through the drive of the second motor and the balancing effect of the tension spring. When it is necessary to change the tension of the decorative paper, the second motor starts according to the tilt direction detected by the gyroscope, and drives the rotating frame to rotate through gear transmission. The rotation of the rotating frame will cause the paper feeding mechanism connected to it to tilt, thereby changing the angle and tension of the decorative paper during the feeding process. At the same time, the tension spring will generate corresponding tension according to the tilt degree of the rotating frame, keeping the two ends of the rotating frame balanced. When the rotating frame tilts to one side, the tension spring will generate tension on the other side to prevent the rotating frame from tilting excessively and to make the rotating frame return to the equilibrium position. This ensures the stability and reliability of the paper feeding mechanism during the adjustment process.

[0018] Preferably, the paper feeding mechanism includes a support plate fixedly connected to the mounting frame and a support assembly fixedly connected to the support plate. The support assembly is rotatably connected to a first mounting shaft, and the first mounting shaft is detachably connected to the support assembly. The decorative paper tube is sleeved on the first mounting shaft.

[0019] By adopting the above technical solution, the paper feeding mechanism is mainly responsible for drawing the decorative paper from the paper tube and conveying it to the cutting mechanism during the decorative paper slitting process. The decorative paper tube is sleeved on the first mounting shaft, which is fixed to the support plate by a support assembly. When the slitting equipment is started, the first mounting shaft rotates under the support of the support assembly, driving the decorative paper tube to rotate, so that the decorative paper is continuously drawn out.

[0020] Preferably, the paper receiving mechanism includes a support assembly fixedly connected to the frame, a second mounting shaft rotatably connected to the support assembly, the second mounting shaft being detachably connected to the support assembly, and a third motor provided on the frame, the third motor driving the second mounting shaft to rotate via belt drive.

[0021] By adopting the above technical solution, during the decorative paper slitting process, the paper take-up mechanism is responsible for winding up the slitting decorative paper. After the third motor starts, it drives the second mounting shaft to rotate via belt drive. As the second mounting shaft rotates, the slitting decorative paper is gradually wound onto the second mounting shaft.

[0022] Preferably, the support assembly includes a mounting plate, a lead screw assembly is fixedly connected to the mounting plate, a handle is fixedly connected to the input end of the lead screw assembly, and a bearing seat is fixedly connected to the moving end of the lead screw assembly.

[0023] By adopting the above technical solution, in the paper feeding mechanism or paper receiving mechanism, the support component plays the role of adjusting the distance between the bearing seats at both ends of the first mounting shaft / second mounting shaft, so that the first mounting shaft / second mounting shaft can be removed from the bearing seats. The operator can turn the handle to drive the lead screw of the lead screw assembly to rotate, thereby adjusting the position of the bearing seats.

[0024] A decorative paper slitting process, characterized by the following specific method: S1. Paper feeding preparation stage: The decorative paper tube is fitted onto the first mounting shaft of the paper feeding mechanism. The support plate and support assembly of the paper feeding mechanism provide stable support for the first mounting shaft. At this time, the decorative paper is in the ready-to-be-drawn state. S2, Decorative Paper Traction Stage: The decorative paper is drawn out from the feeding mechanism and then passes over the guide rollers at both ends of the frame. The guide rollers change the traction direction of the decorative paper, allowing it to move smoothly towards the cutting mechanism; S3, Position Adjustment and Tension Adjustment Stage: When the decorative paper deviates, the air pressure of the first and second air plates and the movement of the lead screw assembly can be adjusted to guide the decorative paper to the required position accurately. During the position adjustment of the decorative paper, the second motor adjusts the angle of the rotating frame, and in conjunction with the action of the tension spring, changes the output angle of the paper feeding mechanism, thereby adjusting the tension of the decorative paper to ensure that the decorative paper is in a suitable tension state when it enters the cutting mechanism. S4. Slitting stage: The decorative paper is cut along the cutting line under the action of the blade; when the position of the decorative paper is offset during the cutting, the balance bar detects the direction and magnitude of the offset through the gyroscope, and re-executes step S3 to adjust the position of the decorative paper so that the blade can cut along the cutting line. S5. Rewinding Stage: The cut decorative paper is rewound by the paper rewinding mechanism.

[0025] By employing the above technical solution, when the decorative paper shifts, the air pumps connected to the first and second air plates come into play. The second air plate increases air pressure to blow the decorative paper towards the first air plate, while the first air plate uses negative pressure to attract the decorative paper. Simultaneously, the lead screw assembly, driven by the first motor, moves precisely to adjust the position of the first air plate, thereby accurately guiding the decorative paper to the desired position. The principle is to use a combination of air pressure and mechanical adjustment to quickly respond to paper shifts and achieve precise adjustment of the paper's position.

[0026] The second motor drives the rotating frame to rotate via gear transmission, changing the output angle of the paper feeding mechanism. Simultaneously, a tension spring generates a force between the rotating frame and the mounting frame, forcing the two ends of the rotating frame to maintain balance. By adjusting the output angle of the paper feeding mechanism, the tension of the decorative paper during transport is changed. The principle is to adjust the paper tension by changing the angle of the paper feeding mechanism, ensuring the paper is in a suitable tension state when entering the cutting mechanism, thus guaranteeing cutting quality.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. Improved cutting accuracy: The first adjustment mechanism can quickly respond to the offset of the decorative paper. The airflow from the second air plate pushes the decorative paper towards the first air plate. Combined with the suction effect of the first air plate and the precise adjustment of the lead screw assembly, this ensures the paper accurately enters the cutting mechanism, greatly reducing cutting errors caused by inaccurate paper positioning and thus improving cutting accuracy. The gyroscope in the detection component can detect paper offset in real time. Once offset is detected, the position adjustment mechanism is immediately triggered, achieving real-time monitoring and adjustment, ensuring the cutting process maintains high precision at all times.

[0028] 2. To ensure the quality of paper cutting, the auxiliary modules in the cutting mechanism, especially the support components, provide stable support for the blades. The design of the limiting groove prevents the blades from bending or deforming during the cutting process, ensuring neat and stable cutting lines, thereby improving the cutting quality. The second adjustment mechanism can adjust the tilt angle of the paper feeding mechanism according to the actual paper conditions, changing the tension of the decorative paper. Appropriate tension can prevent the paper from being too loose or too tight, reducing deformation and damage during the cutting process, and ensuring cutting quality. Attached Figure Description

A second adjusting mechanism 3 is fixedly connected to the frame 1. The slitting mechanism 5 is installed at a position higher than the guide rollers 11 at both ends, and higher than the installation positions of both the paper receiving mechanism 6 and the paper feeding mechanism 2, so that the paper maintains a certain tension during transmission, avoiding paper slack or drifting. This helps to improve the transmission stability of the paper and reduce paper loss. The paper deviates and wrinkles during the conveying process; the first adjustment mechanism 4 is set between the guide roller 11 and the cutting mechanism 5. Before the decorative paper enters the cutting mechanism 5, the first adjustment mechanism 4 adjusts the left and right deviations of the decorative paper to a suitable position so that the cutting component can cut along the cutting line of the decorative paper; during the adjustment process, due to the different forces on the side of the paper, the tension on the left and right sides of the paper is different. The second adjustment mechanism 3 adjusts the tilt angle of the paper feeding mechanism 2 according to the actual situation of the paper to change the tension of the decorative paper. The appropriate tension can avoid the paper being too loose or too tight, and reduce the deformation and damage of the paper during the cutting process.

In this embodiment, there are two support components 7. The first mounting shaft 21 is disposed between the support components 7, so that the first mounting shaft 21 can rotate freely under the support of the support components 7. The first mounting shaft 21 is detachably connected to the support components 7.

The rotating rod 54 is fixed to the mounting blocks 53 by clamping bolts, thus fixing the angle of the rotating rod 54. The blades 56 are fixed to the blades 55 by bolts. In this embodiment... The clamping block 57 is shaped like a hexagonal block, but it can also be an octagonal block or other polygonal blocks. The clamping block 57 is installed on the cutter bar 55 by bolts. When the blade 56 cuts the paper, the end of the blade 56 is embedded in the auxiliary module 59, and the angle of the rotating rod 54 is locked by bolts. At this time, one side of the clamping block 57 presses against the paper surface, making the cutting of the decorative paper more stable. The rotating rod 54 and the cutter bar 55 are connected by a spline, and the position of the cutter bar 55 and the rotating rod 54 is fixed by bolts.

[0038] refer to Figure 5 The auxiliary module 59 includes a housing 58 fixedly connected to the mounting block 53, and a support component 51 and a detection component 52 disposed on the housing 58. When the blade 56 cuts the decorative paper, the support component 51 supports the end of the blade 56, reduces the amplitude of the blade 56 shaking, and increases the quality of the decorative paper cutting. The detection component 52 is used to detect the offset of the decorative paper edge during cutting and to provide feedback to other components. refer to Figure 6 The support component 51 includes a groove 511 disposed on the top surface of the housing 58 and a support block 512 slidably connected to the groove 511. The support block 512 is fixed to the position of the groove 511 by bolts. A limiting groove 513 is provided at the top of the support block 512.

[0039] refer to Figure 7 The detection component 52 includes a groove 521 formed on the top surface of the housing 58. A balance rod 522 is rotatably connected to the side wall of the groove 521. A gyroscope 523 is fixedly connected at the rotation point of the balance rod 522 to detect the rotation state of the balance rod 522. Both ends of the balance rod 522 are bent toward the top surface of the housing 58, and sliders 526 are fixedly connected to both ends. A slider rod 527 passes through the slider 526. The position of the slider rod 527 in the slider 526 can be fixed by bolts, thereby adjusting the relative position of the slider rod 527 and the slider 526. The end of the slide bar 527 is fixedly connected to the force plate 528. When an external force is applied to the force plate 528, it will be transmitted to the balance bar 522 through the slide bar 527 and the slider 526. A pressure plate 524 is fixed to the surface of the housing 58 by bolts. The pressure plate 524 is fixedly connected to a semi-cylinder 525. The semi-cylinder 525 is located in the groove 521. The semi-cylinder 525 makes the paper form an arc shape, which enhances the force on the side of the paper. When the paper shifts, the side of the paper will push the force plate 528. The force plate 528 drives the slider 526 to move through the slide bar 527. The slider 526 then drives the balance bar 522 to tilt. The gyroscope 523 at the rotation point of the balance bar 522 will detect the tilt angle and direction of the balance bar 522 in real time, thereby determining the paper shift.

[0040] refer to Figure 8The first adjustment mechanism 4 includes fixed blocks 41 fixedly connected to both sides of the frame 1. The fixed blocks 41 provide support for the entire first adjustment mechanism 4. The first air plate 42 and the second air plate 43, which are externally connected to air pumps, are also fixedly connected to the fixed blocks 41. The first air plate 42 and the second air plate 43 are respectively set on both sides of the decorative paper. The second air plate 43 increases the air pressure through the external air pump, generating an airflow that blows the decorative paper toward the first air plate 42. The first air plate 42 also generates negative pressure with the help of the external air pump, which can adsorb the decorative paper when it gets close. The first air plate 42 adsorbs the decorative paper and finally adjusts the left and right positions of the decorative paper through the lead screw assembly, thereby adjusting the cutting position of the decorative paper.

[0041] refer to Figure 9 The second adjustment mechanism 3 includes a rotating frame 32 fixedly connected to the mounting frame 31, a rotating frame 32 rotatably connected to the mounting frame 31, and a second motor 33 driving the rotating frame 32 to rotate. The rotating frame 32 is sleeved on the mounting frame 31, and a rotating shaft 35 is fixedly connected to the mounting frame 31. The rotating shaft 35 is rotatably connected to the rotating frame 32. The rotating frame 32 is mounted on a gear coaxially connected to the rotating shaft 35. The second motor 33 drives the rotating frame 32 to rotate through gear transmission. Several tension springs 34 are provided between the rotating frame 32 and the mounting frame 31, and the tension springs 34 force the two ends of the rotating frame 32 to maintain balance. During the decorative paper cutting process, the second adjustment mechanism 3 adjusts the tilt angle of the paper feeding mechanism 2 through the driving of the second motor 33 and the balancing effect of the tension springs 34. When it is necessary to change the tension of the decorative paper, the second motor 33 starts according to the tilt direction detected by the gyroscope 523, and drives the rotating frame 32 to rotate through gear transmission. The rotation of the rotating frame 32 will cause the paper feeding mechanism 2 connected to it to tilt, thereby changing the angle and tension of the decorative paper during the paper feeding process.

[0042] Example 2, a decorative paper slitting process, characterized in that: the specific method includes the following: S1. The decorative paper tube is fitted onto the first mounting shaft 21 of the paper feeding mechanism 2. The support plate 22 of the paper feeding mechanism 2 serves as a basic support component and is fixedly connected to the mounting frame 31, providing a stable support structure for the entire paper feeding mechanism 2. The mounting plate 73 in the support assembly 7 is fixed on the support plate 22, and the mounting plate 73 is connected to the lead screw assembly. The moving end of the lead screw assembly is fixed to the bearing seat 72. By rotating the handle 71, the lead screw assembly can be adjusted, thereby adjusting the position of the bearing seat 72, so that the first mounting shaft 21 can be stably placed between the two support assemblies 7 and detachably connected to the support assemblies 7. At this time, the decorative paper is in a ready-to-be-extracted state, preparing for the subsequent slitting process.

[0043] S2. The decorative paper is drawn out from the paper feeding mechanism 2. The first mounting shaft 21 rotates under the support of the support assembly 7, driving the decorative paper tube to rotate, so that the decorative paper is continuously drawn out. Then, the decorative paper passes over the guide rollers 11 at both ends of the frame 1. The guide rollers 11 are rotatably connected to both ends of the frame 1, and they change the traction direction of the decorative paper, so that the decorative paper can move smoothly towards the cutting mechanism 5.

[0044] S3. Position Adjustment: When the decorative paper shifts during transport, the first adjustment mechanism 4 comes into play. The fixing block 41 in the first adjustment mechanism 4 is fixedly connected to both sides of the frame 1. The first air plate 42 and the second air plate 43, each equipped with an external air pump, are also fixedly connected to the fixing block 41 and are respectively positioned on both sides of the decorative paper. The second air plate 43 increases air pressure to blow the decorative paper towards the first air plate 42, which in turn uses negative pressure to absorb the decorative paper. Simultaneously, the lead screw assembly on the fixing block 41 moves precisely under the drive of the first motor 44. The moving end of the lead screw assembly is fixedly connected to the first air plate 42, thereby adjusting the position of the first air plate 42 and accurately guiding the decorative paper to the desired position.

[0045] Tension Adjustment: During the adjustment of the decorative paper position, the second adjustment mechanism 3 assists in adjusting the tension of the decorative paper. The rotating frame 32 in the second adjustment mechanism 3 is rotatably connected to the mounting frame 31 and connected to the paper feeding mechanism 2. The second motor 33 drives the rotating frame 32 to rotate via gear transmission. Several tension springs 34 are provided between the rotating frame 32 and the mounting frame 31, forcing the two ends of the rotating frame 32 to remain balanced. When the second motor 33 adjusts the angle of the rotating frame 32, the output angle of the paper feeding mechanism 2 changes, thereby adjusting the tension of the decorative paper to ensure that the decorative paper is in a suitable tension state when entering the cutting mechanism 5.

[0046] S4. The decorative paper is cut along the cutting line under the action of the blade 56. The cutting mechanism 5 includes mounting blocks 53 fixedly connected to both sides of the frame 1, a rotating rod 54 rotatably connected to the mounting blocks 53, several blade bars 55 movable along the rotating rod 54, blades 56 mounted on the blade bars 55, a pressing block 57 abutting against the surface of the decorative paper, and an auxiliary module 59 fixedly connected to the mounting blocks 53. The end of the blade 56 is embedded in the auxiliary module 59, and the part of the pressing block 57 abutting against the surface of the decorative paper is located between the end of the blade 56 and the end of the blade bar 55. During the cutting process, the decorative paper is conveyed from the paper feeding mechanism 2, and after being adjusted in position by the first adjusting mechanism 4, it enters the cutting mechanism 5. The blade bars 55 and blades 56 on the rotating rod 54 have been adjusted to the appropriate position according to the cutting requirements, and the pressing block 57 abuts against the surface of the decorative paper to ensure the stability of the paper position. The decorative paper moves relative to the blades 56, and the blades 56 cut the decorative paper.

[0047] The support component 51 in the auxiliary module 59 includes a groove 511 on the top surface of the housing 58, a support block 512 slidably connected to the groove 511, and a limiting groove 513 formed at the top of the support block 512. The width of the limiting groove 513 is 1-1.03 times the thickness of the blade 56, and the blade 56 is embedded in the limiting groove 513. During the cutting of decorative paper, the support component 51 can be adjusted according to the position of the blade 56 by sliding the slider 526 in the groove 511, so that the blade 56 can always be embedded in the limiting groove 513. When the blade 56 is subjected to the reaction force from the decorative paper, the limiting groove 513 will provide support for the blade 56, preventing the blade 56 from bending or deforming. At the same time, the cooperation between the slider 526 and the groove 511 also allows the blade 56 to be adjusted with the movement of the decorative paper during the cutting process, which is suitable for cutting different sizes.

[0048] The detection component 52 includes a groove 521 formed on the top surface of the housing 58, a balance rod 522 rotatably connected to the side wall of the groove 521, a gyroscope 523 fixedly connected to the rotation point of the balance rod 522, force plates 528 disposed at both ends of the balance rod 522, and a clamping plate 524 fixed to the surface of the housing 58 by bolts. Both ends of the balance rod 522 are bent towards the top surface of the housing 58, and sliders 526 are fixedly connected to both ends of the balance rod 522. A sliding rod 527 passes through the slider 526, and the position of the sliding rod 527 within the slider 526 can be fixed by bolts. The end of the sliding rod 527 is fixedly connected to the force plate 528. A semi-cylinder 525 is fixedly connected to the clamping plate 524, and the semi-cylinder 525 is located within the groove 521. During the decorative paper cutting process, when the paper passes through the detection component 52, the semi-cylinder 525 causes the paper to form an arc shape, enhancing the force on the side of the paper. When the paper shifts, the side of the paper pushes the force plate 528. The force plate 528 moves the slider 526 via the slide bar 527. The slider 526 then tilts the balance bar 522. The gyroscope 523 at the rotation point of the balance bar 522 detects the tilt angle and direction of the balance bar 522 in real time, thus determining the paper shift. If the decorative paper shifts during cutting, the balance bar 522 detects the direction and magnitude of the shift via the gyroscope 523. The system then re-executes step S3 to adjust the position of the decorative paper, ensuring that the blade 56 can cut along the cutting line.

[0049] S5. The cut decorative paper is wound up by the paper take-up mechanism 6. The paper take-up mechanism 6 includes a support assembly 7 fixedly connected to the frame 1. The support assembly 7 is rotatably connected to a second mounting shaft 61, which is detachably connected to the support assembly. The frame 1 is equipped with a third motor 62, which drives the second mounting shaft 61 to rotate via belt drive. During the decorative paper cutting process, after the third motor 62 starts, it drives the second mounting shaft 61 to rotate via belt drive. As the second mounting shaft 61 rotates, the cut decorative paper is gradually wound onto the second mounting shaft 61. The mounting plate 73 in the support assembly 7 is fixedly connected to a lead screw assembly. The input end of the lead screw assembly is fixedly connected to a handle 71, and the moving end of the lead screw assembly is fixedly connected to a bearing seat 72. The operator can rotate the handle 71 to drive the lead screw of the lead screw assembly to rotate, thereby adjusting the position of the bearing seat 72 so that the second mounting shaft 61 can be removed from the bearing seat 72.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
