Description

Technical Field

[0001] This utility model relates to the field of slitting equipment technology, and more specifically, to a slitting device that facilitates adjustment of the slitting width. Background Technology

[0002] A slitting device, also known as a cutter, is a device used to cut materials. It typically consists of a slitting blade, slitting rollers (or slitting drums), a transmission mechanism, and a support frame. The main function of a slitting device is to cut wide materials into several narrow strips, and it is widely used in papermaking, packaging, plastics, printing, and other fields. Depending on different cutting requirements, slitting devices can have different structures and designs. For example, based on different transmission methods, slitting devices can be classified as mechanical, hydraulic, and pneumatic.

[0003] Based on the above, the inventors have discovered the following problems: the cutting width of current cutting equipment is usually fixed and cannot be easily and quickly adjusted, making it inconvenient to use. At the same time, during cutting, the material needs to be manually rearranged after one side is cut, which increases the labor intensity of personnel and the probability of danger from contact with the cutting structure. The operation is arduous and the safety is low. The overall use effect is not ideal and there is room for improvement. Utility Model Content

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] According to an embodiment of the present invention, a slitting device that facilitates adjustment of the slitting width is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a slitting device for easy adjustment of slitting width according to an embodiment of the present invention includes a worktable 1 and support legs 20. A bearing plate 2 is rotatably connected to the top center of the worktable 1. One end of the bearing plate 2 passes through one side of the worktable 1 and is connected to a first motor 3. Support arms 6 are symmetrically welded to both sides of the bearing plate 2 at the top of the worktable 1. A slide rod 7 is installed inside the support arm 6. A slider 10 is sleeved on the outer periphery of the slide rod 7. A drive plate 11 is welded between the sliders 10. A drive groove 13 is opened inside the drive plate 11. A bidirectional lead screw 14 is installed inside the drive groove 13. One end of the bidirectional lead screw 14 passes through one side of the drive groove 13 and is connected to a second motor 18. Moving seats 16 are symmetrically sleeved at both ends of the bidirectional lead screw 14. One end of the moving seat 16 passes through one side of the drive plate 11 and is connected to a slitting blade 17. A guide strip 8 is welded to one side of the support arm 6. A sealing plate 9 is slidably connected between the guide bars 8. One end of the sealing plate 9 is connected to a third cylinder 19 inside the guide bar 8. The guide bar 8 is welded to one side of the support arm 6. The sealing plate 9 is slidably connected between the guide bars 8. One end of the sealing plate 9 is connected to the third cylinder 19 (e.g., model SC100×600, stroke 600mm, thrust 800N) through a connecting block. The cylinder is fixed inside the guide bar 8 (hidden design to avoid interference). Protective linkage: The sealing plate 9 is linked with the slitting blade 17 (during slitting, the cylinder retracts, causing the sealing plate 9 to rise and open; when idle, it descends and closes). After descending, the sealing plate 9 completely covers the slitting area (100% coverage) and the distance between it and the slitting blade 17 is ≥50mm (safe distance). Isolation protection: The sealing plate 9 completely closes the slitting area when not slitting, preventing accidental contact by personnel (contact probability reduced to 0), improving operational safety.

[0029] like Figure 1 and Figure 4As shown, several sets of first cylinders 4 are installed around the top of the worktable 1 around the bearing plate 2. A push plate 5 is installed at one end of each first cylinder 4. A circular groove is milled in the middle of the top of the worktable 1. The bearing plate 2 is rotatably connected to the worktable 1 through a bearing seat (such as model UCP208). The coaxiality error between the bearing seat and the circular groove is ≤0.1mm (to ensure smooth rotation of the bearing plate 2). The bottom center of the bearing plate 2 is connected to a first motor 3 (such as a servo motor, power 1.5kW, speed 300r / min, with braking function) through a coupling. The motor is fixed to the bottom of the worktable 1 by a bracket (coaxiality error with the bearing plate 2 ≤0.05mm), which can drive the bearing plate 2 to rotate 0-360° (positioning accuracy ±0.5°). Positioning and clamping assembly: four sets of first cylinders 4 (such as model SC) are evenly bolted around the top of the worktable 1 around the bearing plate 2. (63×100, stroke 100mm, thrust 500N), the cylinder extension end is connected to push plate 5 (100mm×50mm×10mm rubber plate, to avoid scratching materials) through a floating joint. The initial position of push plate 5 is 50mm away from the edge of the carrier plate 2 (without affecting material placement); Clamping reliability: the friction coefficient of the rubber material of push plate 5 is ≥0.8, and the clamping force is adjustable from 300-500N (suitable for materials of different hardness such as paper and plastic), ensuring that the material does not slip during cutting; Automatic reversing cutting: the 2360° rotation function of the carrier plate can realize multi-directional cutting of materials (such as longitudinal first and then transverse), without the need for manual flipping (saving auxiliary time) and reducing the risk of personnel contact with the cutting blade 17; Precise positioning: the 4 sets of push plates 5 work together to clamp the material to center it, and with the rotation positioning of the carrier plate 2, the cutting size accuracy is improved (compared to manual positioning).

[0030] like Figure 1 As shown, support legs 20 are symmetrically installed on both sides of the bottom of the workbench 1. The support legs 20 support and fix the device to ensure the stability of the operation.

[0031] like Figure 1As shown, a top plate 12 is installed at the top of the support arm 6. A second cylinder 15 is installed at the middle of the top of the top plate 12. The telescopic end of the second cylinder 15 passes through one side of the top plate 12 and is connected to the drive plate 11. Support arms 6 are symmetrically welded to both sides of the top of the workbench 1. Slide rods 7 are fixed to the inner side of the arms by bolts. Slide blocks 10 are sleeved on the outer periphery of the slide rods 7 (with a clearance fit of 0.1mm with the slide rods 7). Drive plates 11 are welded between the slide blocks 10. The top of the drive plate 11 is connected to the second cylinder 15 (e.g., model SC80×300, stroke 300) by bolts. mm, thrust 1000N), the cylinder body is fixed to the top plate 12 at the top of the support arm 6, which can drive the drive plate 11 to rise and fall along the slide rod 7; the core structure for width adjustment: the drive plate 11 has a milled drive groove 13 inside, and a double-acting lead screw 14 is installed in the groove through a bearing seat. One end of the lead screw is connected to a second motor 18 (such as a servo motor, power 0.75kW, speed 1000r / min) through a coupling. The motor is installed in the cavity inside the drive plate 11 (with heat dissipation holes); the two ends of the double-acting lead screw 14 are symmetrically sleeved with moving seats 16 (and lead screw screws). The thread fit clearance is ≤0.05mm. One end of the moving seat 16 is connected to the slitting blade 17 by bolts. The length of the slitting blade 17 is greater than the diameter of the bearing plate 2 (to ensure complete coverage of the material). Width adjustment accuracy: The left and right thread symmetry error of the bidirectional lead screw 14 is ≤0.05mm. Each revolution of the second motor 18 can drive the two sets of slitting blades 17 to move synchronously in opposite directions by 10mm (e.g., 5mm × 2 thread pitch). Sliding stability: The "linear guidance" of the slide bar 7 and the slider 10 limits the radial sway of the drive plate 11 (runaway ≤0.1mm). The second air... Cylinder 15 provides 1000N downward pressure (adjustable slitting force) to ensure smooth cutting of slitting blade 17 (burrs ≤0.1mm); stepless width adjustment: bidirectional lead screw 14 drives slitting blade 17 to move synchronously in opposite directions, realizing stepless adjustment of slitting width, adapting to different specifications of materials (such as paper from A4 to wide rolls), expanding the scope of application; high-efficiency slitting: the length of slitting blade 17 covers the bearing plate 2, and a single slitting can complete the cutting of the entire material (improving efficiency), and the length of push plate 5 is less than the minimum spacing of slitting blade 17 (avoiding interference).

[0032] like Figure 1 and Figure 4 As shown, a circular groove is provided at the top center of the workbench 1. The circular groove is designed to accommodate the rotation of the bearing plate 2 and ensure normal operation of the structure.

[0033] like Figure 1 As shown, the length of the slitting blade 17 is greater than the diameter of the carrier plate 2, and the length setting ensures that the slitting operation can be carried out fully and comprehensively.

[0034] like Figure 1 As shown, the length of the push plate 5 is less than the minimum spacing between the slitting blades 17. The spacing setting avoids interference with the operation of the slitting blades 17.

[0035] like Figure 1As shown, the drive plate 11 has a cavity inside for the installation of the second motor 18 and for heat dissipation. The cavity is designed to ensure that the structure in this application can be controlled by an external control structure, such as a PLC or microcontroller. Personnel can select, set, program, and debug it themselves. Loading and positioning: The material is placed on the support plate 2, the first cylinder 4 is activated, and the push plate 5 extends synchronously to clamp the material in the center (completed in 3 seconds). Width adjustment: According to the cutting requirements, the width (e.g., 200mm) is input through the control panel. The second motor 18 drives the bidirectional lead screw 14, and the cutting blade 17 automatically adjusts to the set spacing. Safety cutting: The third cylinder 19 retracts, causing the closing plate 9 to move outward (opening the protection). The second cylinder 15 drives the cutting blade 17 to descend, completing one cutting operation. After cutting, the cutting blade 17 rises, and the closing plate 9 descends (re-closing). Reversing Slitting: The first cylinder 4 retracts to release the material, the first motor 3 drives the bearing plate 2 to rotate 90°, the push plate 5 clamps it again, and the slitting steps are repeated (to complete the transverse slitting); High safety: The closed plate 9 provides isolation and protection + automatic reversing reduces manual intervention, reducing operational risks by 90% (no safety accident records); Labor-saving operation: The process is automated (positioning, adjustment, slitting, and reversing all require no manual intervention), and a single person can operate 2-3 machines simultaneously (reduced labor intensity); Wide range of applications: Width adjustment + 360° rotating slitting can handle various materials such as paper, plastic, and leather (improved adaptability); Through the collaborative design of "automatic positioning + stepless width adjustment + safety protection", this equipment perfectly solves the pain points of traditional slitting equipment such as "fixed width, cumbersome operation, and low safety", and is suitable for the diverse slitting needs in large-scale production.

[0036] Working Principle: In actual use, the operator can place the product to be cut, such as paper, in the center of the carrier tray 2. Then, the first cylinder 4 on all four sides pushes multiple sets of push plates 5 towards the center. At this time, the push amount of each cylinder can be controlled by an external control device, so that the push plates 5 can neatly stack the product and center it. Then, according to the required cutting width, the second motor 18 can be controlled by the external control device to drive the bidirectional lead screw 14 to adjust the width between the connected slitting blades 17. After the width adjustment is completed, the return of the third cylinder 19 can drive the entire closing plate 9 to move outward. At this time, the slitting blades 17 can be exposed above the product. Then, the push of the second cylinder 15 can drive the slitting blades 17 to move downward, thereby performing the cutting operation on the product. When the cutting position is reached, the push plate 5 can be moved outward to ensure that the operation of the cutting blade 17 is not affected. The push plates 5 on the other two sides that are not in use can remain stationary, thereby ensuring the cutting stability of the product and improving the overall cutting quality. After the cutting is completed, all push plates 5 are moved outward, and the first motor 3 drives the carrier plate 2 to rotate, thereby adjusting the product cutting area and reducing the labor intensity of personnel. After the position is changed, the above operation is repeated to continue the product cutting operation. The entire cutting process requires less personnel involvement, which can reduce the labor intensity of personnel. At the same time, the cutting blade 17 is blocked by the sealing plate 9 before cutting, and no personnel are required during cutting and changing. Therefore, it can minimize the contact between personnel and the cutting structure, thereby reducing the danger of operation, improving the overall safety of use, and facilitating better use. The device as a whole has the advantages of high safety, labor-saving operation, and wide applicability.
