Description

Technical Field

[0001] This utility model relates to the field of slitting machine pressure roller technology, and more specifically, to a roller structure for a roller-pressed slitting machine. Background Technology

[0002] Roller slitting machines are key equipment in the production and processing of flexible roll materials such as films, paper, non-woven fabrics, and composite materials. Their core function is to crush and shape the material using pressure rollers and then slit it using cutters. As the actuating component of the equipment, the performance of the pressure roller structure directly affects the flatness, uniformity, and slitting quality of the product.

[0003] Several roller-pressing slitting machines have been developed in the prior art. For example, patent application number 202422449012.4 discloses an auxiliary pressure roller for a slitting machine. The slit bags are conveyed forward by a conveyor roller on the slitting machine support. The auxiliary pressure roller is arranged parallel to the conveyor roller and is hinged to the slitting machine support via a mounting bracket. The hinge axis is parallel to the rotation axis of the conveyor roller. A clamping element is provided on the mounting bracket to apply an elastic clamping force to the conveyor roller, with the clamping force directed towards the roller surface. This invention solves the problem of edge curling of the bag after slitting.

[0004] However, the aforementioned roller pressing slitting machine's roller structure suffers from several drawbacks. The adjustment of the roller spacing is inconvenient, and ensuring synchronization on both sides is difficult, easily leading to uneven roller gaps and affecting the pressing effect. Furthermore, the installation and disassembly of the rollers are cumbersome, requiring significant time for processing materials of different thicknesses or for routine maintenance, thus reducing production efficiency. In addition, the adjustment of the slitting blade position in some slitting machines is often inflexible, making it difficult to quickly adapt to different slitting width requirements.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a roller structure for a roller pressing and slitting machine to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows: A roller structure for a roller press slitting machine includes: a base; a lower roller disposed on top of the base; an upper roller disposed on top of the lower roller; mounting components symmetrically disposed on both sides of the lower and upper rollers; drive motors disposed on one side of the lower and upper rollers, respectively, for independently driving the rotation of the lower and upper rollers; adjusting components disposed on both sides of the mounting components for adjusting the positional distance between the upper roller and the lower roller; a cutting assembly disposed on one side of the base for slitting the material after roller pressing; a control panel disposed at one end of the base; and an unwinding mechanism and a winding mechanism disposed on both sides of the base for realizing the unwinding and winding operations of the material.

[0008] Furthermore, to enable quick disassembly, replacement, and positioning locking of the lower and upper pressure rollers, and to facilitate the replacement of pressure rollers of different specifications to meet the processing needs of various materials, the installation assembly includes brackets symmetrically arranged on both sides of the lower and upper pressure rollers. The brackets are provided with grooves, and a rotating shaft is connected to the bearing on the inner side of the bracket. A hook is provided on the outer side of the rotating shaft. A limit piece is provided on one side of the hook, and a spring is provided on the other side of the hook. A fixing block is provided at one end of the spring, and the fixing block is located inside the bracket. An inclined surface is provided at the end of the hook away from the rotating shaft. The inner surface of the hook matches the outer diameter shape of the shaft end of the lower and upper pressure rollers. The groove is a U-shaped groove opened on the bracket, and its contour matches the outer diameter shape of the shaft end of the lower and upper pressure rollers. The width of the limit piece is greater than the width of the bracket.

[0009] Furthermore, in order to achieve automated adjustment of the gap between the pressure rollers and ensure the stability of the gap under pressure, the adjustment component includes drive blocks symmetrically fixed on the outside of the brackets on both sides of the upper pressure roller. A matching threaded rod is installed inside the drive block. A housing fixed to the top of the base is installed outside the threaded rod. A worm gear is connected to the bottom of the threaded rod through the top of the base. A worm is meshed on the outside of the worm gear. One end of the worm is connected to the output end of a double-headed motor installed inside the base.

[0010] Furthermore, in order to achieve synchronous slitting of the rolled material and adjust the slitting width and lock the cutter position according to different product specifications, the cutter assembly includes a cutter holder symmetrically arranged on one side of the base. Guide grooves are provided on both sides of the top of the cutter holder, and several positioning holes are provided at the top of the cutter holder. Several movable frames that cooperate with it are slidably installed on the outer side of the top of the cutter holder. Protrusions that cooperate with the guide grooves are provided on the inner side of the movable frames. A circular blade support is provided at the top of the movable frames. A rotating shaft is connected to the inner bearing of the circular blade support. A circular blade is fixedly sleeved on the outer side of the rotating shaft. A pin is provided through the top of the movable frame, and the outer side of the pin is matched with the shape of the positioning hole.

[0011] The beneficial effects of this utility model are as follows: 1. Through the coordinated action of the lower pressure roller, upper pressure roller, mounting components, drive motor, adjustment components and cutting components, the integrated synchronous processing of roller pressing and slitting is realized. Furthermore, the mounting components enable quick disassembly and replacement of the pressure rollers and precise positioning and locking, facilitating quick and flexible replacement of the pressure rollers and improving the applicability and maintenance convenience of the equipment.

[0012] 2. By adjusting the dual-head motor of the component, the worm gear meshes with the worm wheel, driving the threaded rod to rotate, thereby controlling the smooth lifting and lowering of the upper pressure roller and realizing the automatic and controllable fine adjustment of the pressure roller gap. The worm gear transmission has a reverse self-locking characteristic to prevent the roller gap from changing due to material pressure during the rolling process, ensuring the stability and reliability of the equipment in continuous working conditions.

[0013] 3. The circular blades in the cutting assembly slide easily under the guide groove of the blade holder and are fixed by the engagement of the pins with the positioning holes at different positions, so that the cutting width can be flexibly adjusted, realizing the rapid conversion of cutting specifications and ensuring the accuracy of the positioning of each circular blade.

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. 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.

[0018] According to an embodiment of the present invention, a roller structure for a roller pressing slitting machine is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the roller structure of the roller press slitting machine according to an embodiment of this utility model includes: a base 1; a lower roller 2, disposed on the top of the base 1; an upper roller 3, disposed on the top of the lower roller 2; mounting components 4, symmetrically disposed on both sides of the lower roller 2 and the upper roller 3; drive motors 5, disposed on one side of the lower roller 2 and the upper roller 3, respectively, for independently driving the lower roller 2 and the upper roller 3 to rotate; adjusting components 6, disposed on both sides of the mounting components 4, for adjusting the positional distance between the upper roller 3 and the lower roller 2; a cutting component 7, disposed on one side of the base 1, for slitting the material after roller pressing; a control panel 8, disposed at one end of the base 1; and an unwinding mechanism 9 and a winding mechanism 10, respectively disposed on both sides of the base 1, for realizing the unwinding and winding operations of the material. Furthermore, it should be noted that the unwinding mechanism 9 and the winding mechanism 10 are existing technologies, using an unwinding shaft and a winding shaft to realize the unwinding and winding operations of the material, which will not be described in detail here.

[0020] With the help of the above technical solution, the integrated synchronous processing of roller pressing and slitting is realized through the coordinated action of the lower pressure roller 2, the upper pressure roller 3, the mounting component 4, the drive motor 5, the adjustment component 6 and the cutter component 7. Furthermore, the mounting component 4 enables the quick disassembly and replacement of the pressure roller and precise positioning and locking, which facilitates quick and flexible replacement of the pressure roller and improves the applicability and maintenance convenience of the equipment.

[0021] Furthermore, it should be noted that the drive motor 5 is uniformly controlled by the control system within the control panel 8. This system employs a synchronous control strategy. The control panel 8 typically has a built-in programmable logic controller (PLC). This PLC sends speed control commands to the drivers of the two drive motors 5 through its high-speed pulse or analog output module, ensuring that the two drive motors 5, which drive the lower pressure roller 2 and the upper pressure roller 3 respectively, maintain synchronized speeds. This ensures that the linear velocities of the two pressure rollers are consistent, guaranteeing stable and uniform rolling pressure on the processed material. Moreover, the lower pressure roller 2 and the upper pressure roller 3 rotate in opposite directions to avoid material stretching, wrinkling, or slippage caused by speed differences. The control panel 8 can independently set and precisely adjust the speed and direction of the two drive motors 5 to adapt to different process requirements. The system can adopt a master-slave control architecture, with one motor designated as the master and the other as the slave. The PLC receives encoder feedback signals from the two drive motors 5 in real time, accurately comparing the deviations in speed and angular displacement. The PLC uses control strategies such as PID algorithms to dynamically adjust the output of the slave motor, ensuring that the lower pressure roller 2 and the upper pressure roller 3 always maintain strict speed and position synchronization.

[0022] In one embodiment, the mounting assembly 4 includes brackets 401 symmetrically arranged on both sides of the lower pressure roller 2 and the upper pressure roller 3. The brackets 401 have grooves 402. A rotating shaft 403 is connected to the inner side of the brackets 401 via a bearing. A hook 404 is provided on the outer side of the rotating shaft 403. A limiting piece 405 is provided on one side of the hook 404, and a spring 406 is provided on the other side of the hook 404. A fixing block 407 is provided at one end of the spring 406 and is located inside the brackets 401. The hook 404 has an inclined surface 408 at the end away from the rotating shaft 403. The inner side of the hook 404 matches the outer diameter shape of the shaft end of the lower pressure roller 2 and the upper pressure roller 3. The groove 402 is a U-shaped groove opened on the bracket 401. Its outline matches the outer diameter shape of the shaft end of the lower pressure roller 2 and the upper pressure roller 3. The width of the limiting piece 405 is greater than the width of the bracket 401, thereby realizing the quick disassembly and replacement of the lower pressure roller 2 and the upper pressure roller 3 and positioning and locking. It is convenient to replace pressure rollers of different specifications to meet the processing needs of various materials.

[0023] The working principle of the mounting component 4 is as follows: When it is necessary to install the upper pressure roller 3 or the lower pressure roller 2, the operator aligns the shaft end of the pressure roller with the groove 402 on the bracket 401 and inserts it. During the insertion process, the shaft end will first contact the inclined surface 408 at the end of the hook 404. Under the action of pressure, the shaft end slides along the inclined surface 408 and pushes the hook 404 to rotate outward around the rotating shaft 403. At this time, the spring 406 is stretched. When the shaft end falls completely into the bottom of the groove 402, the hook 404 quickly rotates inward to reset under the action of the restoring force of the spring 406. The inner side of the hook 404 tightly locks the shaft end of the pressure roller in the groove 402, thereby completing the automatic locking and preventing the pressure roller from coming out during operation. The limiting piece 405 is used to limit the rotation angle of the hook 404 to avoid excessive rotation.

[0024] When it is necessary to disassemble the pressure roller, the operator only needs to pull the limiting piece 405 outward to drive the hook 404 to overcome the elastic force of the spring 406 and rotate outward around the rotating shaft 403, thereby releasing the lock on the end of the pressure roller shaft. At this time, the pressure roller can be directly taken out of the groove 402.

[0025] In one embodiment, the adjustment component 6 includes a drive block 601 symmetrically fixed on the outside of the bracket 401 on both sides of the upper pressure roller 3. A threaded rod 602 is provided inside the drive block 601. A housing 603 fixed to the top of the base 1 is provided outside the threaded rod 602. A worm gear 604 is connected to the bottom of the threaded rod 602 through the top of the base 1. A worm 605 is meshed on the outside of the worm gear 604. One end of the worm 605 is connected to the output end of a double-headed motor 606 provided inside the base 1, thereby realizing the automatic adjustment of the pressure roller gap and ensuring the stability of the roller gap under pressure.

[0026] The working principle of the adjustment component 6 is as follows: When it is necessary to adjust the gap between the upper pressure roller 3 and the lower pressure roller 2 through the control panel 8, the dual-head motor 606 is started. The output shaft of the dual-head motor 606 drives the two worm gears 605 to rotate synchronously. Each worm gear 605 drives the worm wheel 604 meshing with it to rotate. The rotation of the worm wheel 604 then drives the threaded rod 602 connected to it to rotate in the housing 603. Since the drive block 601 and the threaded rod 602 are threadedly engaged, and the drive block 601 is connected to the upper pressure roller 3 through the bracket 401, the rotating threaded rod 602 will force the drive block 601 to move the entire upper pressure roller 3 in the vertical direction, thereby realizing the lifting and lowering of the upper pressure roller 3 and achieving the purpose of adjusting the roller gap.

[0027] It should be noted that the transmission pair formed by the worm gear 604 and the worm 605 has a reverse self-locking characteristic. When the motor stops, the material pressure applied to the upper pressure roller 3 cannot drive the worm gear mechanism in the reverse direction, thereby effectively preventing the roller gap from changing during the pressing process, ensuring the stability of the rolling process and the consistency of the product thickness. The dual-head motor 606 ensures the synchronicity of the adjustment on both sides, avoiding roller gap skew and equipment jamming caused by asynchrony.

[0028] Furthermore, it should be noted that when the control system receives the roller gap adjustment command, it will accurately calculate the required number of output pulses based on the pitch of the threaded rod 602, the transmission ratio of the worm gear 604 and worm 605, and the pulse equivalent of the motor. The dual-head motor 606 rotates the corresponding number of revolutions according to the pulse signal. After the worm gear decelerates and increases the force, it finally drives the threaded rod 602 to rotate at a precise angle, thereby enabling the upper pressure roller 3 to achieve the preset precise vertical displacement and ensuring the digital precision adjustment of the pressure roller gap.

[0029] In one embodiment, the cutter assembly 7 includes a cutter holder 701 symmetrically arranged on one side of the base 1. Guide grooves 702 are provided on both sides of the top of the cutter holder 701. A plurality of positioning holes 703 are provided at the top of the cutter holder 701. A plurality of movable frames 704 that cooperate with the cutter holder 701 are slidably installed on the outer side of the top of the cutter holder 701. A protrusion 705 that cooperates with the guide groove 702 is provided on the inner side of the movable frame 704. A circular blade support 706 is provided at the top of the movable frame 704. A rotating shaft 707 is connected to the inner side of the circular blade support 706 by a bearing. A circular blade 708 is fixedly sleeved on the outer side of the rotating shaft 707. A pin 709 is provided through the top of the movable frame 704. The outer side of the pin 709 is matched with the shape of the positioning hole 703, thereby realizing the synchronous cutting of the material after rolling. The cutting width can be adjusted and the cutter position can be locked according to different product specifications.

[0030] The working principle of the cutter assembly 7 is as follows: When the slitting width needs to be adjusted according to the product specifications, the operator lifts the pin 709 upwards to disengage it from the current positioning hole 703. At this time, the moving frame 704 is unlocked, and the operator can push the moving frame 704 horizontally along the guide groove 702 on the top of the blade holder 701. Since the protrusion 705 on the inner side of the moving frame 704 cooperates with the guide groove 702 on the blade holder 701, the moving frame 704 is constrained in its movement direction and can only slide smoothly in the predetermined direction. After moving the moving frame 704 and the circular blades 708 on it to the target station, the pin 709 is aligned and inserted into the positioning hole 703 corresponding to that position to re-lock. Each circular blade 708 can be adjusted independently. During the slitting operation, the material after being rolled is pulled by the unwinding mechanism 9 and the winding mechanism 10, so that when the material passes over the circular blades 708, it is rotated and cut under the action of the material friction, thereby continuously slitting the material.

[0031] In addition, it should be noted that the control panel 8 consists of a human-machine interface (HMI) and a programmable logic control panel (PLC), and the control panel 8 is electrically connected to the drive motor 5 and the dual-head motor 606; the control panel 8 is existing technology and will not be elaborated on here.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In practical applications, the operator first sets the required parameters through the control panel 8, such as the distance between the upper pressure roller 3 and the lower pressure roller 2, the speed of the two drive motors 5, and the width of the slitting. The roll of material to be processed is then installed on the unwinding mechanism 9, and the material belt is guided to pass through the roller pressing area and the slitting area in sequence, and finally fixed on the core of the winding mechanism 10. After that, the equipment is started. The drive motors 5 drive the lower pressure roller 2 and the upper pressure roller 3 to rotate synchronously in opposite directions at the set speed. At the same time, the winding mechanism 10 provides a stable traction force. Under the action of the traction force, the material is smoothly output from the unwinding mechanism 9 and enters the gap between the two pressure rollers. When the material passes through the gap controlled by the adjusting component 6, it is subjected to uniform rolling action to achieve shaping, leveling or thinning (the working principle of the adjusting component 6 is as described above). The material after being rolled is then conveyed to the cutting component 7 area. The material is cut from the circular blade. The material passes over the sheet 708, and the material is pulled by the unwinding mechanism 9 and the winding mechanism 10. The material is rotated and cut by the circular blade 708 under the friction of the material, and the continuous wide material is cut into multiple products of a predetermined width (the working principle of the cutter assembly 7 is as described above). The multiple products after cutting are neatly wound and collected by the winding mechanism 10. When it is necessary to replace or maintain the pressure roller, simply manually pull the limiting piece 405 on the mounting assembly 4 outward, so that the hook 404 rotates around the rotating shaft 403 and stretches the spring 406, which can release the lock on the pressure roller shaft end and remove the pressure roller from the groove 402 of the bracket 401. During installation, the pressure roller shaft end is directly placed into the groove 402. It rotates by squeezing the inclined surface 408 of the hook 404 and automatically returns to the locked position under the action of the spring 406 (the working principle of the mounting assembly 4 is as described above).

[0034] In summary, by utilizing the above-mentioned technical solution of this utility model, the integrated synchronous processing of roller pressing and slitting is achieved through the synergistic action of the lower pressure roller 2, upper pressure roller 3, mounting assembly 4, drive motor 5, adjusting assembly 6, and cutting assembly 7. Furthermore, the mounting assembly 4 enables rapid disassembly and replacement of the pressure rollers, as well as precise positioning and locking, facilitating quick and flexible replacement and improving the applicability and maintenance convenience of the equipment. The dual-head motor 606 of the adjusting assembly 6 drives the worm gear 605 to mesh with the worm wheel 604, thereby rotating the threaded rod 602 and controlling the upper pressure roller 3 to rotate smoothly. The lifting mechanism enables automatic and controllable fine-tuning of the pressure roller gap. The worm gear 604 and worm 605 transmission have a reverse self-locking characteristic to prevent changes in the roller gap caused by material pressure during the rolling process, ensuring the stability and reliability of the equipment in continuous operation. The circular blades 708 in the cutter assembly 7 slide conveniently under the guidance of the guide groove 702 of the blade holder 701, and are fixed by the pins 709 and the positioning holes 703 at different positions, so that the slitting width can be flexibly adjusted, realizing the rapid conversion of slitting specifications and ensuring the accuracy of the positioning of each circular blade 708.
