Description

Technical Field

[0001] This utility model relates to the technical field of paper slitting devices, specifically a high-speed slitting device for self-adhesive composite paper. Background Technology

[0002] Self-adhesive composite paper, as a material that integrates label printing and pasting functions, is widely used in various fields such as product identification, logistics packaging, and daily chemical labels due to its convenient pasting characteristics and good printability. With the rapid development of modern industry, the demand for self-adhesive composite paper in various industries has shown explosive growth, requiring not only a significant increase in output but also higher standards for slitting accuracy and efficiency. High-speed slitting equipment, as a key piece of equipment to ensure the production efficiency and product quality of self-adhesive composite paper, can quickly slit large rolls of composite paper into small rolls that meet specifications, greatly improving production efficiency and meeting the market's demand for rapid product delivery. Therefore, it occupies an indispensable position in the production process of self-adhesive composite paper.

[0003] Traditional self-adhesive composite paper slitting devices have many limitations in practical applications. On the one hand, some devices are operated manually or semi-automatically, resulting in slow slitting speeds that are difficult to meet the needs of large-scale production, leading to low production efficiency and an inability to respond to market orders in a timely manner. On the other hand, traditional equipment has shortcomings in slitting precision control. The position adjustment of the cutting head is not precise enough, which can easily lead to slitting size deviations, resulting in material waste and increased production costs. In addition, traditional devices lack effective control over paper tension and flatness, which can easily cause paper wrinkles and misalignment during the slitting process, seriously affecting slitting quality and product qualification rate, thus hindering the high-quality development of the self-adhesive composite paper production industry. To address these issues, we have proposed a high-speed self-adhesive composite paper slitting device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-speed slitting device for self-adhesive composite paper, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a high-speed slitting device for self-adhesive composite paper, including a worktable;

[0006] A fixed frame is fixedly connected to the top of the workbench, and two telescopic rods are fixedly connected to the top of the inner wall of the fixed frame.

[0007] A fixing plate is fixedly connected to the bottom output end of the telescopic rod;

[0008] The inner walls of the fixed frame are fixedly connected to slide rails on both sides, and the slide rails are perpendicular to the horizontal plane;

[0009] A second slide rail is fixedly connected to one end of the top of the fixed plate, and the second slide rail is perpendicular to the output direction of the slide rail.

[0010] A movable block is slidably connected to the top of the second slide rail, and a stepper motor is fixedly connected to one end of the top of the movable block;

[0011] A gear is fixedly connected to one end of the rotating shaft of the stepper motor, and a rack is fixedly connected to the top of the fixed plate near the second slide rail.

[0012] The rack is parallel to the second slide rail, and the gear and rack are meshed together.

[0013] Preferably, a limit socket is provided at the top of the moving block away from the stepper motor;

[0014] A fixing rod is provided above the limiting socket, and the bottom of the fixing rod is inserted into one end of the inner wall of the limiting socket.

[0015] The bottom output end of the fixed rod extends to the bottom of the moving block.

[0016] Preferably, a spring is fixedly connected to the bottom of the inner wall of the limiting socket, and the spring is sleeved on one end of the outer wall of the fixing rod;

[0017] The top of the spring contacts the bottom of the outer edge of the fixing rod.

[0018] Preferably, the two sides of the outer wall of the fixing rod are tightly pressed against the top two sides of the inner wall of the limiting socket;

[0019] The outer walls of the fixed rod are threaded with hexagonal socket head cap screws on both sides, and the bottom of the hexagonal socket head cap screws is threaded to the top of the moving block.

[0020] Preferably, a cutting head is fixedly connected to the bottom of the fixing rod.

[0021] Preferably, a feeding roller is movably connected to one end of the top of the worktable, and an auxiliary pressure roller is movably connected to the end of the top of the worktable near the fixed frame.

[0022] The auxiliary pressure roller has five equidistant rubber rings fitted onto its outer wall.

[0023] Preferably, a take-up roller is movably connected to the top of the worktable away from the feeding roller, and a motor is fixedly connected to the outer wall of one side of the worktable;

[0024] The motor's rotating shaft is fixedly connected to a connecting shaft on one side of the take-up roller.

[0025] Compared with the prior art, this utility model provides a high-speed slitting device for self-adhesive composite paper, which has the following beneficial effects:

[0026] 1. This high-speed self-adhesive composite paper slitting device, compared to traditional slitting devices that often rely on manual operation for adjusting the cutting position and height (which is inefficient and difficult to guarantee accuracy, easily leading to deviations in slitting dimensions and material waste), achieves precise lateral movement of the moving block through the linkage of a stepper motor, gears, and racks. The telescopic rod, in conjunction with the fixed plate, allows for precise adjustment of the cutting height. Compared to traditional manual adjustment, this device can control the slitting accuracy error within a very small range, greatly improving slitting accuracy, reducing material waste, and lowering production costs. It is particularly suitable for high-end label production scenarios with high slitting accuracy requirements.

[0027] 2. Compared to traditional semi-automatic or manual slitting devices, which require frequent manual intervention during the slitting process (such as manually adjusting the cutting position, manually feeding, and rewinding), this high-speed self-adhesive composite paper slitting device is cumbersome and inefficient. This device achieves automatic rewinding by driving a motor-driven rewinding roller, which, together with the feeding roller and auxiliary pressure roller, forms an automated paper conveying system. Furthermore, the adjustment functions of the stepper motor and telescopic rod eliminate the need for repeated manual adjustments to the cutting components, significantly reducing manual operation. This allows for rapid fulfillment of large-scale production needs, effectively improving enterprise production efficiency and market competitiveness, and is particularly suitable for production tasks with large order volumes and tight delivery schedules.

[0028] 3. Compared to traditional slitting devices, which lack effective control over paper flatness and cutting head stability, leading to issues like paper wrinkling, misalignment, and cutting head wobbling during slitting, this high-speed self-adhesive composite paper slitting device effectively flattens the paper during transport, ensuring smooth paper delivery. The linkage between the fixing rod, spring, and limit socket, along with the secure locking of the fixing rod with hex bolts, ensures the stability of the cutting head during slitting. These multiple safeguards effectively prevent paper wrinkling, misalignment, and inconsistent cutting dimensions compared to traditional devices, significantly improving slitting quality, increasing product qualification rate and quality, and enhancing the company's product reputation and market standing.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-3 A high-speed slitting device for self-adhesive composite paper includes a workbench 1. The workbench 1 serves as the basic load-bearing component of the entire device, providing an installation platform for other structures and playing a role in stably supporting the entire slitting device.

[0035] The top of the workbench 1 is fixedly connected to a fixed frame 2. The top of the inner wall of the fixed frame 2 is fixedly connected to two equidistant telescopic rods 3. The telescopic rods 3 can extend and retract, and by extending and retracting, they drive the fixed plate 4 to move up and down, thereby adjusting the height of the cutting component to meet the cutting needs of paper of different thicknesses.

[0036] The bottom output end of the telescopic rod 3 is fixedly connected to a fixing plate 4. The fixing plate 4 is used to install the second slide rail 6 and other cutting-related components, combining the components into a whole, which serves to support and fix the cutting components.

[0037] The inner walls of the fixed frame 2 are fixedly connected to the slide rails 5 on both sides. The slide rails 5 are perpendicular to the horizontal plane. The slide rails 5 provide guidance for the up and down movement of the fixed plate 4, ensuring the stability and accuracy of the movement of the fixed plate 4, and playing the role of guiding the vertical movement of the fixed plate 4.

[0038] A second slide rail 6 is fixedly connected to one end of the top of the fixed plate 4. The output direction of the second slide rail 6 is perpendicular to that of the slide rail 5. The second slide rail 6 provides a track for the lateral movement of the moving block 7, so that the moving block 7 can be adjusted in the horizontal direction, thereby guiding the moving block 7 to slide laterally and adjusting the cutting position.

[0039] The top of the second slide rail 6 is slidably connected to a moving block 7. One end of the top of the moving block 7 is fixedly connected to a stepper motor 8. The moving block 7 is used to install components such as the stepper motor 8 and move on the second slide rail 6 to drive the cutting head 15 to make lateral displacement, thereby bearing the components and realizing the effect of lateral movement adjustment.

[0040] A gear 9 is fixedly connected to one end of the rotating shaft of the stepper motor 8, and a rack 10 is fixedly connected to one end of the top of the fixed plate 4 near the second slide rail 6.

[0041] The rack 10 is parallel to the second slide rail 6, and the gear 9 is meshed with the rack 10. The stepper motor 8 is driven by the meshing of the gear 9 and the rack 10, which converts the rotational motion of the motor into the linear motion of the moving block 7, thereby achieving the effect of precisely controlling the lateral movement distance and speed of the moving block 7.

[0042] A limit socket 11 is provided at the top of the moving block 7 away from the stepper motor 8. The limit socket 11 is used to insert the fixing rod 12 and limit the movement of the fixing rod 12 within a certain range, thereby limiting the position of the fixing rod 12 and ensuring the stability of the cutting head 15.

[0043] A fixing rod 12 is provided above the limiting socket 11, and the bottom of the fixing rod 12 is inserted into one end of the inner wall of the limiting socket 11.

[0044] The bottom output end of the fixed rod 12 extends to the bottom of the moving block 7. The fixed rod 12 is used to connect the cutting head 15 and move within the limiting socket 11 to transmit the cutting force to the cutting head 15, thereby supporting and transmitting the cutting force.

[0045] A spring 13 is fixedly connected to the bottom of the inner wall of the limiting socket 11, and the spring 13 is sleeved on one end of the outer wall of the fixing rod 12;

[0046] The top of the spring 13 contacts the bottom of the outer edge of the fixing rod 12.

[0047] The outer sides of the fixing rod 12 are tightly pressed against the top sides of the inner wall of the limiting socket 11;

[0048] The outer walls of the fixed rod 12 are threaded with hexagonal socket bolts 14 on both sides, and the bottom of the hexagonal socket bolts 14 is threaded to the top of the movable block 7.

[0049] The bottom of the fixing rod 12 is fixedly connected to the cutting head 15.

[0050] A feeding roller 16 is movably connected to one end of the top of the workbench 1, and an auxiliary pressure roller 17 is movably connected to one end of the top of the workbench 1 near the fixed frame 2.

[0051] The auxiliary pressure roller 17 has five equally spaced rubber rings 18 fitted on its outer wall. The auxiliary pressure roller 17 and the rubber rings 18 work together to flatten the paper and assist in its conveying, preventing the paper from wrinkling or shifting. This achieves the effect of flattening the paper and assisting in its conveying, thus ensuring the quality of the slitting process.

[0052] A take-up roller 20 is movably connected to the top of the workbench 1 away from the feeding roller 16, and a motor 19 is fixedly connected to the outer wall of one side of the workbench 1.

[0053] The rotating shaft of motor 19 is fixedly connected to the connecting shaft on one side of the take-up roller 20.

[0054] Working principle: First, the motor 19 is linked with the take-up roller 20 to achieve the effect of traction of the self-adhesive composite paper. The motor 19, as the power source, has its rotating shaft fixed to the connecting shaft on one side of the take-up roller 20. After starting, it drives the take-up roller 20 to rotate. The rotation of the take-up roller 20 generates traction force, causing the self-adhesive composite paper to be pulled out from the feed roller 16, passing under the auxiliary pressure roller 17, and moving towards the take-up roller 20, providing continuous paper conveying power for the slitting process. Next, the telescopic rod 3 is linked with the fixed plate 4 to achieve the effect of adjusting the cutting height. The two telescopic rods 3 at the top of the inner wall of the fixed frame 2 have their bottom output ends fixed to the fixed plate 4. When it is necessary to adjust the height of the cutting head 15, the telescopic rods 3 extend and retract, driving the fixed plate 4 to move up and down in the vertical direction, thereby adjusting the cutting height. The entire cutting assembly (including the second slide rail 6, moving block 7, fixed rod 12, and cutting head 15, etc.) fixed on the fixed plate 4 moves up and down synchronously to adapt to different thicknesses of self-adhesive composite paper or slitting requirements. The stepper motor 8, gear 9, and rack 10 are linked to achieve the effect of lateral movement of the moving block 7. The second slide rail 6 at the top of the fixed plate 4 is perpendicular to the output direction of the slide rail 5. The moving block 7 is slidably connected to the second slide rail 6. The stepper motor 8 is fixed to the top of the moving block 7. The gear 9 on its rotating shaft meshes with the rack 10 on the fixed plate 4. When the stepper motor 8 rotates, the gear 9 rolls on the rack 10, driving the moving block 7 to move laterally along the second slide rail 6, thereby enabling the fixed rod 12 and cutting head 15 fixed on the moving block 7 to achieve lateral displacement and adjust the cutting position. The fixed rod 12, spring 13, and limit socket 11 are linked to achieve the elastic pressing and resetting effect of the cutting head 15. The bottom of the fixed rod 12 is inserted into the limit socket 11 of the moving block 7, and the bottom output end extends to the bottom of the moving block 7 and connects to the cutting head 15. The spring 13 at the bottom of the inner wall of the limit socket 11 is sleeved on the outer wall of the fixed rod 12, and the top of the spring 13 contacts the bottom of the outer edge of the fixed rod 12. The hexagonal socket bolt 14 is linked with the fixed rod 12 to achieve the effect of locking the position of the fixed rod 12. The two sides of the outer wall of the fixed rod 12 are tightly pressed against the top two sides of the inner wall of the limit socket 11. By tightening the hexagonal socket bolt 14, its bottom is threadedly connected to the top of the moving block 7, thereby firmly fixing the fixed rod 12 in the limit socket 11 and preventing the fixed rod 12 from moving during the cutting process. The auxiliary pressure roller 17 and the rubber ring 18 are linked to ensure the stability and precision of the cutting head 15. Five equidistant rubber rings 18 are fitted onto the outer wall of the auxiliary pressure roller 17 at the top of the worktable 1. When the self-adhesive composite paper passes under the auxiliary pressure roller 17, the auxiliary pressure roller 17 rotates under the traction force of the paper. The rubber rings 18 increase the friction with the paper and simultaneously flatten it, preventing wrinkles and shifting during the slitting process and ensuring slitting quality. The feeding roller 16, auxiliary pressure roller 17, and take-up roller 20 are linked to achieve continuous conveying of the self-adhesive composite paper. The feeding roller 16 releases the self-adhesive composite paper, the auxiliary pressure roller 17 assists in flattening and conveying, and the take-up roller 20 is driven by the motor 19 to rewind it.The combination of these three elements ensures that the paper passes through the slitting area continuously at a stable speed and tension, achieving continuity and high efficiency in high-speed slitting operations.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
