Description

Technical Field

[0001] This invention relates to the field of slitting device technology, and in particular to a multi-blade adaptive slitting device and method for decorative paper. Background Technology

[0002] Decorative paper, as a core decorative material for building materials such as furniture, cabinets, flooring, and fireproof boards, requires a smooth, even surface, uniform color, and clear patterns. It also needs good opacity, impregnation properties, and printability to adapt to subsequent processing techniques. In the decorative paper production process, the slitting process is a crucial link between roll production and downstream applications. It requires precisely slitting wide master rolls into narrow rolls or sheets of different specifications to meet diverse market demands. With the rapid development of the building decoration industry, the market has placed increasingly higher demands on the diversity of decorative paper specifications, slitting precision, and production efficiency. Traditional slitting equipment and methods are gradually becoming inadequate for the industry's development needs.

[0003] Currently, most decorative paper slitting equipment uses a fixed blade holder structure, where the roller blades are fixed to the rollers using tightening bolts to achieve the slitting function. This type of equipment has many limitations in practical applications, mainly in the poor flexibility of blade spacing adjustment. When switching between different slitting specifications, it is necessary to manually loosen the tightening bolts one by one to adjust the blade position, which is cumbersome, time-consuming, and results in low changeover efficiency. It is difficult to meet the needs of small-batch, multi-specification customized production. Therefore, we propose a multi-blade adaptive slitting device and method for decorative paper. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-blade adaptive slitting device and method for decorative paper, which solves the problem of poor flexibility in adjusting the blade spacing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-blade adaptive slitting device for decorative paper, comprising a rotary blade and a concave roller disposed on one side of the rotary blade. A mounting plate is disposed on the side of the concave roller facing away from the rotary blade. A single-stage electric slide rail is embedded in the inner wall of the mounting plate facing the rotary blade. An auxiliary rotating rod is fixedly mounted on the side of the single-stage electric slide rail facing the rotary blade. An upper roller shaft is rotatably mounted on the side of the auxiliary rotating rod facing the rotary blade. The upper roller shaft passes through and is disposed at the center position of the rotary blade, and the rotary blade slides against the outer wall of the upper roller shaft. An electrically movable sliding component is assembled on the side of the rotary blade facing away from the concave roller. A main rotating rod is rotatably mounted on the side of the mounting plate facing away from the concave roller. A lower roller shaft is fixedly mounted at one end of the main rotating rod that passes through the inner wall of the mounting plate. The lower roller shaft passes through and is disposed at the center position of the concave roller, and the concave roller slides against the outer wall of the lower roller shaft.

[0006] Preferably, the side of the electrically movable slide facing the roller blade is integrally formed with two sets of locking plates. The two sets of locking plates are respectively parallel to each other on the bottom end face of the electrically movable slide, and the roller blade is rotatably mounted between the two sets of locking plates via a rotating shaft.

[0007] Preferably, an electric slide is fixedly installed at the center position of the side of the electric sliding slide opposite to the snap-fit ​​plate, and a connecting connector is fixedly connected to the side of the electric sliding slide perpendicular to the electric slide.

[0008] Preferably, a second linkage gear is installed through and rotatably on one end of the upper roller shaft facing the auxiliary rotating rod. The second linkage gear meshes with a first linkage gear on the side facing the main rotating rod. A fixed rod is inserted into the side of the first linkage gear facing the center of the mounting plate, and the first linkage gear is rotatably connected around the fixed rod.

[0009] Preferably, a drive gear is provided on the side of the fixed rod away from the linkage gear 2, and the drive gear 1 meshes with the linkage gear 1 for transmission. The drive gear 1 is fixedly installed on the main rotating rod at the center position facing the main rotating rod, and a motor is fixedly installed on the end of the main rotating rod away from the drive gear 1.

[0010] Preferably, the inner wall of the roller blade facing the upper roller shaft is integrally formed with a slot block 1, and a matching limiting groove 1 is provided on the upper roller shaft at a corresponding position to the slot block 1; the inner wall of the concave roller facing the lower roller shaft is integrally formed with a slot block 2, and a matching limiting groove 2 is provided on the lower roller shaft at a corresponding position to the slot block 2; and a position sensor is fixedly installed on the outer wall of the concave roller facing the main rotating rod.

[0011] Preferably, a top mounting component is fixedly installed on the top end face of the mounting bracket facing the electric sliding component, and a multi-stage slide rail control component is movably installed on the side of the top mounting component facing the electric sliding component. The electric sliding component is slidably connected to the multi-stage slide rail control component on the side facing the multi-stage slide rail control component.

[0012] Preferably, the multi-stage slide rail control component has a slider integrally formed on the side facing the top mounting component, and the top mounting component has a matching vertical slide groove at the position corresponding to the slider. The mounting bracket plate has four sets of mounting blocks integrally formed on the side away from the roller blade.

[0013] Preferably, a multi-blade adaptive slitting method for decorative paper includes the following steps: S1. The decorative paper roll is placed at the feed end of the device so that the end of the roll can pass through the gap between the upper and lower rollers in sequence, and fit the corresponding positions of the roller blade and the concave roller. The mounting blocks on the mounting plate ensure that the device is fixed and stable.

[0014] S2. Based on the target cutting width, the electric sliding component on the electric moving component is driven by the control signal connected through the connector. The electric sliding component slides along the multi-stage slide rail control component, which drives the roller blade connected to the snap plate to slide along the first limiting slide groove of the upper roller shaft. At the same time, the concave roller is adjusted to slide along the second limiting slide groove of the lower roller shaft. The position information is fed back in real time by the position sensor on the concave roller, and the alignment adjustment of multiple sets of roller blades and concave rollers is completed.

[0015] S3. Start the motor to drive the main rotating rod to rotate. The main rotating rod drives the first drive gear to rotate. The first drive gear meshes with the first linkage gear, and the first linkage gear meshes with the second linkage gear, which in turn drives the upper roller shaft and the lower roller shaft to rotate synchronously. The roller blades rotate with the upper roller shaft to cut the decorative paper. The concave rollers rotate synchronously to assist in conveying the cut decorative paper.

[0016] S4. During the slitting process, the position sensor continuously detects the relative position of the concave roller and the roller blade. If a deviation occurs, the control system drives the single-stage electric slide rail to adjust the position of the auxiliary rotating rod, or the electric moving slide is used to finely adjust the roller blade spacing to ensure slitting accuracy. The slitting decorative paper is collected from the discharge end.

[0017] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the upper roller shaft is raised and lowered as a whole by a single-stage electric slide rail, ensuring that the roller blade is precisely embedded in the central groove of the concave roller, forming a stable cutting fit structure. This effectively improves the stability and accuracy of the cutting process, avoids cutting deviations caused by blade misalignment, and ensures smooth and even cutting edges. The electrically movable sliding mechanism allows for flexible sliding distribution of the roller blade on the upper roller shaft, simultaneously driving the concave roller to slide synchronously. This eliminates the need for an additional independent drive mechanism to achieve synchronous adaptation of the blade distance and roller distance, simplifying the equipment's adjustment logic, reducing operational complexity, significantly improving the switching efficiency for different cutting sizes, reducing downtime for adjustments, and enhancing the equipment's production adaptability.

[0018] This synchronous sliding design allows the equipment to be widely adapted to various cutting tasks without the need to replace the cutter rollers or roller assemblies. This not only reduces the cost of spare parts and the difficulty of maintenance, but also expands the applicability of the equipment, enhancing its versatility and practicality. The overall structure is integrated into the mounting plate, with a compact and reasonable layout and smooth linkage between components. This reduces transmission backlash and energy loss, improves the reliability and service life of the equipment, and replaces manual calibration with an integrated automatic adjustment method, reducing the intensity of manual operation, improving the level of production automation, and contributing to the overall improvement of production efficiency. In summary, this design, through structural linkage optimization, achieves a synergistic improvement in cutting adaptability, ease of operation, and cutting quality, fully ensuring production stability and efficiency while adapting to diverse production needs.

Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0025] refer to Figures 1-5 The decorative paper multi-blade adaptive slitting device shown includes a roller blade 3 and a concave roller 4 disposed on one side of the roller blade 3. A specific embodiment is shown below: Example 1 A mounting plate 1 is provided on the side of the concave roller 4 facing away from the roller blade 3. The mounting plate 1 serves as the load-bearing base of the overall structure. A single-stage electric slide rail 101 is fixed to its inner side wall facing the roller blade 3 by an embedded assembly method, providing a power mounting base for the lifting and adjusting of the upper roller shaft 5. A top mounting component 2 is fixed to the top end face of the mounting plate 1 facing the electric moving slide 7 by bolts. A multi-stage slide rail control component 8 is movably mounted on the side of the top mounting component 2 facing the electric moving slide 7. The electric slide component 703 on the electric moving slide 7 is correspondingly slidably embedded in the multi-stage slide rail control component 8 to achieve smooth guiding and sliding of the electric moving slide 7.

[0026] To accommodate vertical adjustment requirements, a slider 801 is integrally formed on the side of the multi-stage slide rail control component 8 facing the top mounting component 2. A matching vertical groove 201 is provided on the top mounting component 2 at the position corresponding to the slider 801. The sliding engagement between the slider 801 and the vertical groove 201 allows for fine-tuning of the vertical position of the multi-stage slide rail control component 8. In addition, four sets of symmetrically distributed mounting blocks 102 are integrally formed on the side of the mounting plate 1 away from the roller blade 3. The mounting blocks 102 can be used to firmly fix the entire device to the production station, ensuring structural stability during the slitting process.

[0027] Example 2 An auxiliary rotating rod 904 is welded and fixedly installed on the side of the single-stage electric slide rail 101 facing the roller blade 3. The auxiliary rotating rod 904 is used to realize the rotation support and lifting linkage of the upper roller shaft 5. A second linkage gear 905 is rotatably installed through the upper roller shaft 5 facing the auxiliary rotating rod 904 and through a bearing. The side of the second linkage gear 905 facing the main rotating rod 9 forms a meshing transmission cooperation with the first linkage gear 903. A fixing rod 902 is inserted into the side of the first linkage gear 903 facing the center position of the mounting plate 1. The fixing rod 902 is fixedly connected to the mounting plate 1, and the first linkage gear 903 can rotate flexibly around the fixing rod 902 through the bearing.

[0028] A drive gear 901 is located on the side of the fixed rod 902 away from the linkage gear 905. The drive gear 901 meshes with the linkage gear 903 for transmission. The drive gear 901 is coaxially fixedly installed at the end of the main rotating rod 9 facing the fixed rod 902. The end of the main rotating rod 9 away from the drive gear 901 is fixedly installed with a motor 906 via a coupling. After the motor 906 is started, the power is transmitted to the drive gear 901 through the main rotating rod 9, and then drives the linkage gear 903 and the linkage gear 905 to rotate in sequence through gear meshing, ultimately realizing the synchronous rotation of the upper roller shaft 5 and the lower roller shaft 6, providing stable power for the slitting operation.

[0029] Example 3 An upper roller shaft 5 is rotatably mounted on the side of the auxiliary rotating rod 904 facing the roller blade 3 via a bearing. The upper roller shaft 5 passes through and is positioned at the center of the roller blade 3. The roller blade 3 slides against the outer wall of the upper roller shaft 5, ensuring that the roller blade 3 can slide axially along the upper roller shaft 5. A main rotating rod 9 is rotatably mounted on the side of the mounting plate 1 away from the concave roller 4 via a bearing. A lower roller shaft 6 is fixedly mounted on one end of the main rotating rod 9 that passes through the inner wall of the mounting plate 1. The lower roller shaft 6 passes through and is positioned at the center of the concave roller 4. The concave roller 4 slides against the outer wall of the lower roller shaft 6. To ensure guiding accuracy during sliding adjustment, a retaining block 301 is integrally formed on the inner wall of the roller blade 3 facing the upper roller shaft 5. A matching limiting groove 501 is provided on the upper roller shaft 5 at the position corresponding to the retaining block 301. The retaining block 301 is embedded in the limiting groove 501 to prevent the roller blade 3 from shifting during sliding.

[0030] Similarly, a slot block 401 is integrally formed on the inner wall of the concave roller 4 facing the lower roller shaft 6, and a matching limiting groove 601 is provided on the lower roller shaft 6 at the position corresponding to the slot block 401, so as to realize the precise guiding sliding of the concave roller 4. A position sensor 402 is fixedly installed on the outer wall of the concave roller 4 facing the main rotating rod 9, which is used to collect the relative position data between the concave roller 4 and the roller blade 3 in real time.

[0031] Example 4 An electrically movable slide 7 is mounted on the side of the roller blade 3 facing away from the concave roller 4. Two sets of parallel locking plates 702 are integrally formed on the side of the electrically movable slide 7 facing the roller blade 3. The two sets of locking plates 702 are located on the bottom end face of the electrically movable slide 7. The roller blade 3 is rotatably mounted between the two sets of locking plates 702 via a rotating shaft, ensuring that the roller blade 3 moves synchronously with the electrically movable slide 7 without affecting its own rotation and cutting. An electric slide 703 is fixedly installed at the center of the side of the electrically movable slide 7 facing away from the locking plates 702. The electric slide 703 slides in cooperation with the multi-stage slide rail control component 8. A connecting connector 701 is fixedly connected to the side of the electrically movable slide 7 perpendicular to the electric slide 703. A control signal is received through the connecting connector 701 to drive the electric slide 703, thereby causing the roller blade 3 to slide along the upper roller shaft 5 to adjust the spacing. During the slitting process, the position sensor 402 continuously detects the relative position of the concave roller 4 and the roller blade 3. If a positional deviation is detected, the control system can be linked to adjust the overall slitting accuracy.

[0032] Working principle of this invention: I. Working principle of the slitting device First, the single-stage electric slide rail 101 on the inner wall of the mounting plate 1 and the auxiliary rotating rod 904 constitute a lifting and adjusting mechanism, which can drive the upper roller shaft 5 and the roller blade 3 to lift as a whole, providing a basis for the precise alignment of the roller blade 3 and the concave roller 4.

[0033] Secondly, the electric moving slide 7 is fixed to the roller blade 3 by the snap-fit ​​plate 702, and the electric slide 703 at its top slides in sliding cooperation with the multi-stage slide rail control component 8. With the help of the control signal connected by the wire connector 701, the roller blade 3 can be driven to slide along the upper roller shaft 5 to achieve spacing adjustment.

[0034] Then, the fitting and engagement of the first slot block 301 with the first limiting slide groove 501 and the second slot block 401 with the second limiting slide groove 601 ensure that the roller blade 3 and the concave roller 4 do not deviate during the adjustment process. In terms of power transmission, the motor 906 drives the main rotating rod 9 to rotate, and through the meshing transmission of the first drive gear 901, the first linkage gear 903, and the second linkage gear 905, it drives the upper roller shaft 5 and the lower roller shaft 6 to rotate synchronously, providing stable power for slitting.

[0035] Finally, the position sensor 402 collects the relative position data of the concave roller 4 and the roller blade 3 in real time, providing feedback for adaptive fine-tuning.

[0036] II. Working Principle of the Slitting Method The first step is positioning pretreatment, where the decorative paper roll is fixed on one side between the upper roller 5 and the lower roller 6 to ensure alignment between the feeding equipment and the slitting device. The second step is parameter adaptive adjustment, where, based on the target width, the control signal drives the electric moving slide 7 to slide the roller blade 3, simultaneously adjusting the position of the concave roller 4. Precise alignment is achieved with feedback from the position sensor 402. The third step is linkage slitting, where the motor 906 drives the upper and lower rollers to rotate synchronously via gear transmission. The roller blade 3 rotates with the upper roller 5 to achieve slitting, and the concave roller 4 rotates synchronously to assist in conveying, ensuring that the slitting and conveying rhythms are consistent. The fourth step is dynamic correction, where the position sensor 402 continuously detects position deviations during slitting. The control system adjusts the position of the upper roller 5 or fine-tunes the spacing of the roller blades 3 by driving the single-stage electric slide rail 101 to correct deviations in real time, ensuring slitting accuracy. Finally, slitting is completed and the finished product is collected.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
