Description

Technical Field

[0001] The present 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 Art

[0002] In the current field of decorative paper processing, the cutting of decorative paper is undoubtedly a crucial link. For a long time, the main cutting method is to use a sharp straight knife or a disc knife, and apply a certain pressure to make the blade of the knife cut into the decorative paper. When the knife moves along the predetermined cutting line, the decorative paper is cut by the shear force of the blade.

[0003] However, the prior art has obvious disadvantages. During the cutting process, the decorative paper will have a functional deviation, which causes the cutter to easily deviate from the original cutting line. This greatly reduces the cutting accuracy and makes it difficult to meet the requirements of high-precision processing of decorative paper. On the other hand, the cutter deviates from the cutting line, resulting in an uneven cutting edge, which greatly affects the aesthetics of the decorative paper and the subsequent use effect.

[0004] Therefore, for the improvement and innovation of decorative paper cutting technology, it is necessary to focus on solving the problems of poor precision and uneven edges caused by decorative paper offset, so as to improve the quality and reliability of decorative paper cutting and better meet the ever-changing needs of the decoration industry. Summary of the invention

[0005] The purpose of the present application is to provide a multi-knife slitting device and a decorative paper slitting process in order to improve the cutting accuracy of decorative paper.

[0006] A multi-blade slitting device provided in the present application adopts the following technical solution: it includes a frame, guide rollers rotatably connected to both ends of the frame, a paper feeding mechanism arranged at one end of the frame, a paper receiving mechanism arranged at the other end of the frame, a cutting mechanism arranged between the paper feeding mechanism and the paper receiving mechanism, a first adjustment mechanism arranged between the cutting mechanism and the paper feeding mechanism, and a second adjustment mechanism for adjusting the inclination angle of the paper feeding mechanism. The decorative paper is pulled out from the paper feeding mechanism, bypasses the guide roller to change the traction direction, passes through the first adjustment mechanism, and the first adjustment mechanism adjusts the position of the decorative paper before entering the cutting mechanism. During the process of adjusting the position of the decorative paper, the second adjustment mechanism assists the first adjustment mechanism in adjusting the force of the decorative paper. The decorative paper enters the cutting mechanism and is cut along the cutting line. The cut decorative paper is rolled up by the paper receiving 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 accuracy and quality of cutting. During the paper position adjustment process, the tension changes. The second adjustment mechanism adjusts the inclination 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 to avoid the paper being loose or too tight, which affects 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, a plurality of knife rods movable along the rotating rods, a blade mounted on the knife rod, a pressing block abutting against the surface of the decorative paper, and an auxiliary module fixedly connected to the mounting blocks, the end of the blade is embedded in the auxiliary module, and the portion where the pressing block abuts against the surface of the decorative paper is located between the end of the blade and the end of the knife rod.

[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 being adjusted in position by the first adjusting mechanism, it enters the slitting mechanism; the knife bar and the blade on the rotating rod have been adjusted to a suitable position according to the slitting requirements, and the pressing block abuts against its surface to ensure that the position of the paper is stable; the decorative paper moves relative to the blade, and the blade slits the decorative paper.

[0010] Preferably, the auxiliary module includes a shell fixedly connected to the mounting block, and a supporting component and a detecting component arranged on the shell, the supporting component includes a slide groove arranged on the top surface of the shell, a supporting block slidably connected to the slide groove, and a limiting groove opened on the top of the supporting 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, during the decorative paper slitting process, the blade needs to maintain a stable position and angle to ensure the accuracy and quality of slitting. The support component can be adjusted according to the position of the blade through the sliding of the slider in the slide groove, so that the blade can always be embedded in the limiting groove. When the blade is subjected to the reaction force from the decorative paper, the limiting groove will provide support for the blade to prevent the blade from bending or deformation. At the same time, the cooperation of the slider and the slide groove can also enable the blade to be adjusted as the decorative paper moves during the slitting process, which is suitable for slitting of different sizes.

[0012] Preferably, the detection component includes a groove opened on the top surface of the shell, a balance bar rotatably connected to the side wall of the groove, a gyroscope fixedly connected to the rotation point of the balance bar, a force plate arranged at both ends of the balance bar, and a clamping plate fixed to the surface of the shell by bolts. The two ends of the balance bar are bent toward the top surface of the shell, and both ends of the balance bar are fixedly connected to sliders, and the slider has a sliding rod passing through it, and the position of the sliding rod in the slider can be fixed by bolts, and the end of the sliding rod is fixedly connected to the force plate, and the clamping plate is fixedly connected to a semi-cylinder, and 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 makes the paper form an arc, thereby increasing the force on the side of the paper. When the paper deviates, the side of the paper will push the force plate, and the force plate drives the slider to move through the slide bar, and the slider drives the balance bar to tilt. The gyroscope on the rotation point of the balance bar will detect the tilt angle and direction of the balance bar in real time, thereby determining the paper deviation.

[0014] Preferably, the first adjusting mechanism includes a fixed block fixedly connected to both sides of the frame, a first air plate externally connected to an air pump, a second air plate externally connected to an air pump, and a screw assembly arranged on the fixed block, the first air plate and the second air plate are both fixedly connected to the fixed block, the moving end of the screw assembly is fixedly connected to the first air plate, the first air plate and the second air plate are respectively arranged on both sides of the decorative paper, and the fixed block is provided with a first motor for driving the screw assembly.

[0015] By adopting the above technical solution, when the decorative paper deviates, the second air plate can quickly blow the decorative paper toward the first air plate by increasing the air pressure, and the first air plate absorbs the decorative paper and adjusts it to a suitable position through the screw assembly. This pneumatic adjustment method has a fast response speed and can respond to the deviation of the paper in a short time, preventing the paper from continuing to deviate from the correct position, thereby reducing the slitting error that may be caused by the deviation of the paper; because the second air plate blows the decorative paper toward 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 and rotatably connected to the mounting frame, and a second motor driving 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, a plurality of 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, and the top end of the rotating frame is fixedly connected to the support plate.

[0017] By adopting the above technical solution, during the decorative paper slitting process, the second adjustment mechanism adjusts the inclination angle of the paper feeding mechanism through the drive of the second motor and the balancing effect of the tension spring. When the tension of the decorative paper needs to be changed, the second motor is started according to the inclination direction detected by the gyroscope, and drives the rotating frame to rotate through the gear transmission. The rotation of the rotating frame will drive the paper feeding mechanism connected thereto to tilt, thereby changing the angle and tension of the decorative paper during the paper feeding process. At the same time, the tension spring will generate corresponding tension according to the inclination degree of the rotating frame to keep 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 prompt the rotating frame to return to a balanced position, thereby ensuring 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, a support assembly fixed to the support plate, the support assembly is rotatably connected to a first mounting shaft, the first mounting shaft is detachably connected to the support assembly, and 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, and the first mounting shaft is fixed to the support plate through the support assembly. When the slitting device 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 collection mechanism includes a support assembly fixedly connected to the frame, the support assembly is rotatably connected to a second mounting shaft, the second mounting shaft is detachably connected to the support assembly, the frame is provided with a third motor, and the third motor drives the second mounting shaft to rotate through a belt drive.

[0021] By adopting the above technical solution, during the decorative paper slitting process, the paper collection mechanism is responsible for rolling up the slit decorative paper. After the third motor is started, the second installation shaft is driven to rotate through the belt transmission. As the second installation shaft rotates, the slit decorative paper is gradually rolled up onto the second installation shaft.

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

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

[0024] A decorative paper cutting process, characterized in that: the specific method includes the following: S1, paper feeding preparation stage: the decorative paper tube is sleeved on 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 a state to be drawn out; S2, Decorative paper pulling stage: The decorative paper is pulled out from the paper feeding mechanism and then passes around the guide rollers at both ends of the frame. The guide rollers change the pulling direction of the decorative paper so that the decorative paper can move smoothly towards the direction of the cutting mechanism; S3, position adjustment and tension adjustment stage: when the decorative paper is offset, the decorative paper can be accurately guided to the desired position by adjusting the air pressure of the first air plate and the second air plate and the movement of the screw assembly; during the decorative paper position adjustment process, the second motor adjusts the angle of the rotating frame, cooperates with the tension spring to change the output angle of the paper feeding mechanism, and then adjusts the tension of the decorative paper to ensure that the decorative paper is in a suitable tension state when entering the cutting mechanism; S4, cutting stage: the decorative paper is cut along the cutting line under the action of the blade; when the decorative paper is offset during cutting, the balance bar detects the direction and magnitude of the offset of the decorative paper 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 rewinded by the paper collecting mechanism.

[0025] By adopting the above technical solution, when the decorative paper is offset, the air pumps connected to the first and second air plates come into play. The second air plate blows the decorative paper toward the first air plate by increasing the air pressure, and the first air plate absorbs the decorative paper by negative pressure. At the same time, the screw assembly moves precisely under the drive of the first motor 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 the offset of the paper and achieve precise adjustment of the paper position.

[0026] The second motor drives the rotating frame to rotate through gear transmission, changing the output angle of the paper feeding mechanism. At the same time, the 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 state of the decorative paper during the transmission process is changed. The principle is to adjust the tension of the paper by changing the angle of the paper feeding mechanism, so that the paper is in a suitable tension state when entering the slitting mechanism, ensuring the slitting quality.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Improve the accuracy of slitting. The first adjustment mechanism can respond quickly to the deviation of the decorative paper. The airflow of the second air plate pushes the decorative paper to the first air plate. Combined with the adsorption of the first air plate and the precise adjustment of the screw assembly, the paper is ensured to enter the slitting mechanism accurately, which greatly reduces the slitting error caused by inaccurate paper position, thereby improving the slitting accuracy. The gyroscope in the detection component can detect the deviation of the paper in real time. Once the deviation is found, the position adjustment mechanism is immediately triggered, realizing real-time monitoring and adjustment, so that the slitting process always maintains a high-precision state.

[0028] 2. To ensure the quality of paper slitting, the auxiliary modules in the slitting mechanism, especially the supporting components, provide stable support for the blade. The design of the limiting groove makes it difficult for the blade to bend or deform during the slitting process, ensuring the neatness and stability of the cutting line, thereby improving the slitting quality. The second adjustment mechanism can adjust the inclination angle of the paper feeding mechanism according to the actual situation of the paper and change the tension of the decorative paper. Appropriate tension can prevent the paper from being loose or too tight, reduce the deformation and damage of the paper during the slitting process, and ensure the slitting quality.

The end of the slide bar 527 is fixedly connected to the force plate 528. The clamping plate 524 is fixedly connected to a semi-cylinder 525, and the semi-cylinder 525 is located in the groove 521. During the decorative paper cutting process, when the paper passes through the detection assembly 52, the semi-cylinder 525 makes the paper form an arc, thereby enhancing the force on the side of the paper. When the paper is offset, the side of the paper will push the force plate 528, and the force plate 528 drives the slider 526 to move through the slide bar 527, and the slider 526 drives the balance bar 522 to tilt. The gyroscope 523 on the rotation point of the balance bar 522 will detect the tilt angle and direction of the balance bar 522 in real time, so as to determine the paper offset. If the decorative paper is offset during cutting, the balance bar 522 detects the direction and size of the decorative paper offset through the gyroscope 523, and the system will re-execute step S3 to adjust the decorative paper position so that the blade 56 can cut along the cutting line.
