Description

Technical Field

[0001] This application belongs to the technical field of metal cutting, and more specifically, relates to a steel coil slitting device. Background Technology

[0002] Slitting of steel coils is one of the core processes in the precision processing of metal strips. It is widely used in the processing and production of various metal coils such as cold-rolled steel strips, galvanized steel strips, color-coated steel strips, and electrical steel strips. Its function is to cut wide steel coils longitudinally into several narrow strips of a set width to meet the material needs of downstream industries such as pipe manufacturing, stamping, hardware forming, and transformer core processing.

[0003] Existing steel coil slitting machines include a frame and a cutter shaft. Multiple sets of blades are arranged on the cutter shaft along its own axis. Adjacent blades are axially positioned by annular washers. A locking nut is provided at the end of the cutter shaft to press and fix all the blades and washers axially. The axial thickness of the washers ensures the spacing accuracy between the blades.

[0004] When it is necessary to adjust the slitting width or change the blade spacing, the corresponding operation method is as follows: First, shut down the slitting production line, unlock the bearing seats at both ends of the cutter shaft from the frame, and remove the entire cutter shaft from the frame using hoisting equipment; then, unscrew the locking nut at the end of the cutter shaft, and remove all the disc blades and spacers in sequence along the axial direction; calculate the required shim thickness according to the new slitting width, reselect and add or subtract shims of the corresponding thickness, and then install the shims and blades back onto the cutter shaft one by one in sequence, tighten the end locking nut to complete the blade positioning; finally, hoist the entire cutter shaft back to its original position.

[0005] The above-mentioned tool shaft spacing adjustment process is cumbersome, time-consuming, and difficult to adapt to the production needs of multiple specifications and small batches, and frequent switching of width specifications, resulting in low overall spacing adjustment efficiency. Summary of the Invention

[0006] The purpose of this application is to provide a steel coil slitting device to solve the technical problem of low blade spacing adjustment efficiency in the prior art.

[0007] To achieve the above objectives, the technical solution adopted in this application is: to provide a steel coil slitting device, including a frame and a cutter shaft horizontally arranged on the frame, wherein multiple sets of adjusting holes are formed along their own axial direction on the outer circumferential surface of the cutter shaft, and a central hole communicating with the multiple sets of adjusting holes is coaxially formed at one end of the cutter shaft; the steel coil slitting device further includes: Multiple cutter sets correspond one-to-one with multiple sets of the aforementioned adjusting hole sets, and are coaxially spaced on the cutter shaft; Multiple sets of translation components correspond one-to-one with multiple sets of adjusting hole groups. Each translation component includes a translation screw and a translation sleeve. The translation screw is coaxially rotatably disposed within the central hole and located at the corresponding adjusting hole group. The translation sleeve is threadedly connected to the translation screw. The inner side of the cutter group passes through the adjusting hole group and is fixedly connected to the translation sleeve. An adjustment mechanism is provided on the frame and extends into the central hole. The adjustment mechanism is used to drive the translation screw to rotate individually.

[0008] In one possible implementation, based on the above technical solutions, a through hole is coaxially formed at the end of the translation screw, and a through groove is formed on the inner wall of the through hole along its axial direction; the adjustment mechanism includes: A drive shaft is coaxially disposed within the central hole and passes through all the through holes, with the outer end of the drive shaft extending out of the central hole; A limiting strip is fixed on the outer circumferential surface of the drive shaft and close to the inner end of the drive shaft.

A drive assembly, mounted on the frame and connected to the drive shaft, is used to drive the drive shaft to rotate or move along its own axial direction; and A switching component is disposed on the frame and connected between the drive shaft and the drive assembly. The switching component is used to adjust the switching of the drive assembly's action on the drive shaft.

[0009] In one possible implementation, based on the above technical solutions, the driving component includes: A drive sleeve is rotatably mounted on the frame and threadedly connected to the drive shaft. The drive motor is mounted on the frame; and The gear set is connected between the output shaft of the drive motor and the drive sleeve. The switching component is used to guide or deguide the drive shaft to slide along its own axial direction.

[0010] In one possible implementation, based on the above technical solutions, the switching component includes: A limiting sleeve is rotatably mounted on the frame and keyed to the drive shaft; A support base is mounted on the frame and supported at the bottom of the limiting sleeve; A pressure plate is disposed above the limiting sleeve and directly opposite the support base; and A drive cylinder is vertically mounted on the frame and connected to the pressure plate. The drive cylinder is used to press the pressure plate against the limiting sleeve to fix the limiting sleeve.

[0011] In one possible implementation, based on the above technical solutions, the number of rotations of each translation screw driven by the drive shaft and the limiting bar are both integers; the steel coil slitting device further includes: A positioning mechanism is disposed on the frame and extends into the central hole. The positioning mechanism is used to simultaneously fix or release all of the translation screws.

[0012] In one possible implementation, based on the above technical solutions, a positioning groove is formed along the axial direction of the inner wall of the perforation, and the positioning mechanism includes: A through rod is slidably disposed within the central hole and passes through all the translational threaded sleeves, with the outer end of the through rod extending to the outside of the central hole; Multiple positioning strips, each corresponding to one of the multiple translation screws, are fixed to the through rod. The positioning strips are used to insert into the corresponding positioning slots. A positioning component is disposed on the frame and connected to the through rod, the positioning component being used to drive the through rod to slide axially along the drive shaft.

[0013] In one possible implementation, based on the above technical solutions, the positioning component includes: A movable plate is slidably mounted on the frame, and the sliding direction of the movable plate is parallel to the axial direction of the drive shaft; A rotating ring, rotatably mounted on the movable plate and fixed to the outer end of the through rod, is coaxially arranged with the drive shaft; and A positioning cylinder is horizontally mounted on the frame and connected to the moving plate. The positioning cylinder is used to drive the moving plate to slide.

[0014] In one possible implementation, based on the above technical solutions, there are two positioning cylinders, which are symmetrically arranged along the axis of the through rod.

[0015] In one possible implementation, based on the above technical solutions, each of the translation screws is provided with a connecting seat at both ends, the connecting seat comprising: The outer ring is coaxially fixed to the inner circumferential surface of the central hole; Multiple inner blocks are fixed at intervals on the inner circumferential surface of the outer ring, and there is a gap between the inner blocks and the drive shaft, the gap allowing the positioning strip to pass through; and The connecting ring is coaxially fixed to the end face of the translation screw and rotatably connected to the plurality of inner blocks.

[0016] In one possible implementation, based on the above technical solutions, the adjusting hole group includes four circumferentially distributed strip-shaped holes on the cutter shaft; the cutter group includes: The tool holder is coaxially sleeved on the tool shaft; The cutter head is coaxially fixed on the cutter holder; and Four connecting blocks are slidably connected to the four strip holes one by one, and the connecting blocks are fixed between the cutter head and the translational screw sleeve.

[0017] The beneficial effects of the steel coil slitting device provided in this application are as follows: Compared with the prior art, this application opens multiple sets of adjusting holes on the outer circumference of the cutter shaft and opens a central hole at the end of the cutter shaft that connects all the adjusting holes. The translation component is built into the central hole and is powered by the adjustment mechanism set on the frame. The rotation of the translation screw can drive the translation sleeve to move axially. The inner side of the cutter group passes through the adjusting holes and forms a linkage with the translation sleeve, thereby realizing the position adjustment of the cutter group along the axial direction of the cutter shaft.

[0018] Compared to traditional shim-type spacing adjustment, which requires multiple steps such as stopping the machine, hoisting the cutter shaft, disassembling the blades and shims, re-selecting and reassembling, and reinstalling, this application eliminates the need to hoist the cutter shaft out of the frame and disassemble the blades and spacers one by one. The tool spacing can be adjusted directly on the frame, simplifying the spacing adjustment process, reducing manual operation, lowering the labor intensity of spacing adjustment, and helping to improve the efficiency of tool spacing adjustment. It is suitable for production needs with multiple specifications, small batches, and frequent changes in width specifications.

[0019] Meanwhile, the threaded transmission structure of the translation screw and translation sleeve can ensure the positional accuracy of the cutter group and maintain the consistency of the slitting width; multiple sets of translation components are set one-to-one with the cutter group, which can realize the independent adjustment of each set of cutters, making it easy to flexibly configure different slitting width specifications and improve the adaptability of the device to different production needs.

The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0028] The steel coil slitting device provided in this application will now be described.

[0029] like Figures 1 to 4 As shown, one embodiment of this application provides a steel coil slitting device, including a frame 1 and a cutter shaft 2 horizontally arranged on the frame 1. Multiple sets of adjustment holes 21 are formed on the outer circumferential surface of the cutter shaft 2 along its own axial direction. A central hole communicating with the multiple sets of adjustment holes 21 is coaxially formed at one end of the cutter shaft 2. The steel coil slitting device also includes a cutter group 3, a translation component 4 and an adjustment mechanism 5.

[0030] There are multiple cutter groups 3, which correspond one-to-one with the adjusting hole group 21. The multiple cutter groups 3 are coaxially spaced on the cutter shaft 2.

[0031] The translation component 4 has multiple sets, which correspond one-to-one with the adjustment hole group 21. The translation component 4 includes a translation screw 41 and a translation screw sleeve 42. The translation screw 41 is coaxially rotatably disposed in the central hole and located at the corresponding adjustment hole group 21. The translation screw sleeve 42 is threadedly connected to the translation screw 41. The inner side of the cutter group 3 passes through the adjustment hole group 21 and is fixedly connected to the translation screw sleeve 42.

[0032] The adjustment mechanism 5 is mounted on the frame 1 and extends into the center hole. The adjustment mechanism 5 is used to drive the translation screw 41 to rotate individually.

[0033] Compared with the prior art, the steel coil slitting device provided in this embodiment opens multiple sets of adjusting hole groups 21 on the outer circumferential surface of the cutter shaft 2, and opens a central hole at the end of the cutter shaft 2 that connects all the adjusting hole groups 21. The translation component 4 is built into the central hole and is powered by the adjustment mechanism 5 set on the frame 1. The rotation of the translation screw 41 drives the translation screw sleeve 42 to move axially. The inner side of the cutter group 3 passes through the adjusting hole group 21 and forms a linkage with the translation screw sleeve 42, thereby realizing the position adjustment of the cutter group 3 along the axial direction of the cutter shaft 2.

[0034] Compared to traditional shim-type spacing adjustment, which requires multiple steps such as stopping the machine, hoisting the cutter shaft 2, disassembling the blades and shims, re-selecting and reassembling, and reinstalling, this application eliminates the need to hoist the cutter shaft 2 out of the frame 1 and disassemble the blades and spacers one by one. The spacing of the cutter group 3 can be adjusted directly on the frame 1, simplifying the spacing adjustment process, reducing manual operation, lowering the labor intensity of the spacing adjustment operation, and helping to improve the efficiency of blade spacing adjustment. It is suitable for production needs of multiple specifications, small batches, and frequent switching of width specifications.

[0035] Meanwhile, the threaded transmission structure of the translation screw 41 and the translation sleeve 42 can ensure the positional accuracy of the knife group 3 and maintain the consistency of the slitting width; multiple translation components 4 are set one-to-one with the knife group 3, which can realize the independent adjustment of each knife group 3, making it easy to flexibly configure different slitting width specifications and improve the adaptability of the device to different production needs.

[0036] like Figures 4 to 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The translation screw 41 has a through hole coaxially opened at its end, and a through groove 411 is opened on the inner wall of the through hole along its axial direction; the adjustment mechanism 5 includes a drive shaft 51, a limit bar 52, a drive assembly 53 and a switching assembly 54.

[0037] The drive shaft 51 is coaxially disposed in the central hole and passes through all the through holes. The outer end of the drive shaft 51 extends out of the central hole, and the inner end of the drive shaft 51 is coaxially rotatably connected in the central hole. The outer end of the drive shaft 51 is rotatably connected to the frame 1. The limiting strip 52 is fixed on the outer circumferential surface of the drive shaft 51 and close to the inner end of the drive shaft 51. The limiting strip 52 is used to insert into the through groove 411.

[0038] The drive assembly 53 is mounted on the frame 1 and connected to the drive shaft 51. The drive assembly 53 is used to drive the drive shaft 51 to rotate or move along its own axis. The switching assembly 54 is mounted on the frame 1 and connected between the drive shaft 51 and the drive assembly 53. The switching assembly 54 is used to adjust the action switching of the drive assembly 53 on the drive shaft 51.

[0039] By opening a through hole with a through slot 411 coaxially at the end of the translation screw 41, and cooperating with the drive shaft 51 that passes through all the through holes and the limiting strip 52 fixed on the drive shaft 51, the axial movement of the drive shaft 51 can allow the limiting strip 52 to be inserted into or disengaged from the through slot 411 of the corresponding translation screw 41, thereby realizing the power docking and switching between a single drive shaft 51 and different translation screws 41.

[0040] Multiple translation screws 41 can be driven to rotate by a single drive assembly 53, eliminating the need for a separate drive source for each translation screw 41. This greatly simplifies the internal structure of the central hole, reduces manufacturing costs and control complexity, and facilitates later maintenance and repair.

[0041] The drive assembly 53 can drive the drive shaft 51 to complete two actions: rotation or movement along its own axis. In conjunction with the switching assembly 54, the action mode can be switched, making the power transmission switching process smoother and more reliable. This facilitates precise control of the target tool group 3 that needs to be adjusted, avoids erroneous movement of non-target tool groups 3, and ensures the accuracy of the distance adjustment process.

[0042] like Figure 4 and Figure 6 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The drive assembly 53 includes a drive sleeve 531, a drive motor 532, and a gear set 533. The drive sleeve 531 is rotatably mounted on the frame 1 and threadedly connected to the drive shaft 51; the drive motor 532 is mounted on the frame 1.

[0043] The gear set 533 is connected between the output shaft of the drive motor 532 and the drive sleeve 531. In this embodiment, the gear set 533 includes two meshing spur gears, one of which is coaxially fixed to the output shaft of the drive motor 532, and the other is coaxially fixed to the drive sleeve 531.

[0044] The switching component 54 is used to guide or deguide the drive shaft 51 to slide along its own axial direction.

[0045] The structure adopts a drive motor 532 and a gear set 533 to drive the drive screw sleeve 531 to rotate. The drive screw sleeve 531 is threadedly connected to the drive shaft 51, which can convert the rotational motion of the drive motor 532 into the rotation or axial movement of the drive shaft 51. The transmission process is smooth and the transmission ratio is accurate. It can accurately control the rotation angle and axial displacement of the drive shaft 51, thereby improving the accuracy of the position adjustment of the tool set 3.

[0046] The gear set 533 can adapt to the speed and torque matching between the drive motor 532 and the drive screw sleeve 531, ensuring the stability of power output and reducing energy loss during transmission. The drive screw sleeve 531 is rotatably mounted on the frame 1, with good structural load-bearing capacity and low vibration during operation, which can maintain the long-term stability of transmission accuracy.

[0047] By combining the guiding and deguiding control of the axial sliding of the drive shaft 51 by the switching component 54, the motion mode of the drive shaft 51 can be flexibly switched to meet the power requirements of different working conditions such as tool group 3 position adjustment and power docking switching.

[0048] like Figures 4 to 6 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The switching assembly 54 includes a limiting sleeve 541, a support base 542, a pressure plate 543, and a drive cylinder 544. The limiting sleeve 541 is rotatably mounted on the frame 1 and is keyed to the drive shaft 51. The support base 542 is mounted on the frame 1 and supported at the bottom of the limiting sleeve 541.

[0049] The pressure plate 543 is positioned above the limiting sleeve 541 and directly opposite the support base 542. The drive cylinder 544 is vertically mounted on the frame 1 and connected to the pressure plate 543. The drive cylinder 544 is used to press the pressure plate 543 onto the limiting sleeve 541 to fix the limiting sleeve 541.

[0050] The sum of the thread friction between the drive sleeve 531 and the drive shaft 51 and the rotational friction between the drive sleeve 531 and the frame 1 is greater than the sum of the thread friction between the translation screw 41 and the translation sleeve 42, the rotational friction between the translation screw 41 and the cutter shaft 2, and the sliding friction between the cutter assembly 3 and the cutter shaft 2. Based on this, when the pressure plate 543 does not press down and fix the limit sleeve 541, the rotation of the drive shaft 51 driven by the drive assembly 53 ensures that the limit strip 52 drives the corresponding translation screw 41 to rotate, and the drive sleeve 531 remains relatively fixed to the drive shaft 51, so that the rotation of the translation screw 41 drives the cutter assembly 3 to slide.

[0051] The limiting sleeve 541 and the drive shaft 51 are connected by a key, which allows the drive shaft 51 to slide relative to each other in the axial direction and can stably transmit circumferential torque. The driving cylinder 544 drives the pressure plate 543 to press down, pressing the limiting sleeve 541 onto the support seat 542, which can fix the limiting sleeve 541 in the circumferential direction, thereby restricting the circumferential rotation of the drive shaft 51. At this time, when the driving screw sleeve 531 rotates, the drive shaft 51 will move in the axial direction, realizing the docking and switching of the limiting strip 52 with different translation screws 41.

[0052] When the pressure plate 543 releases its pressure on the limiting sleeve 541, the limiting sleeve 541 can rotate together with the drive shaft 51. At this time, the drive shaft 51 rotates circumferentially and its axial position remains fixed, which can drive the docking translation screw 41 to rotate, thus completing the position adjustment of the tool assembly 3.

[0053] The motion mode of drive shaft 51 can be switched by clamping and releasing, with clear control logic, making it easy to operate and maintain. At the same time, the clamping method of support base 542 and pressure plate 543 provides uniform fixing force on limit sleeve 541, ensuring a stable fixing state, which can withstand torque load during transmission and is not prone to slippage failure.

[0054] like Figures 5 to 6 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The number of rotations of each translation screw 41 driven by the drive shaft 51 and the limit bar 52 are all integers. If the spacing between adjacent tool groups 3 needs to be equal, the number of rotations of the translation screw 41 is increased sequentially along the direction from the inner end to the outer end of the center hole. For example, the first translation screw 41 rotates one rotation, the second translation screw 41 rotates two rotations, the third translation screw 41 rotates three rotations, and so on. This way, multiple tool spacing adjustments can be made to maintain equal spacing.

[0055] The steel coil slitting device also includes a positioning mechanism 6, which is mounted on the frame 1 and extends into the center hole. The positioning mechanism 6 is used to simultaneously fix or release all translation screws 41.

[0056] The number of rotations of each translation screw 41 driven by the drive shaft 51 and the limit bar 52 is set to an integer, so that the circumferential position of the translation screw 41 remains fixed after each adjustment, and the circumferential angle of the slot 411 is always consistent, which makes it easy for the positioning mechanism 6 to uniformly fix all translation screws 41 in the circumferential direction.

[0057] The positioning mechanism 6 can simultaneously fix or release all translation screws 41. After the position of the tool group 3 is adjusted, it can lock the circumferential position of all translation screws 41, alleviate the tendency of the translation screws 41 to move circumferentially during the slitting process, reduce the possibility of axial displacement of the tool group 3, and ensure the stability of the spacing between the tool groups 3 and the accuracy of the slitting process.

[0058] Meanwhile, the unified fixing method eliminates the need to lock each group of translation screws 41 separately, simplifying the locking process after adjustment, improving the overall efficiency of the distance adjustment operation, and facilitating automated control.

[0059] like Figures 5 to 6 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The inner wall of the perforation is provided with a positioning groove 412 along its axial direction. The positioning mechanism 6 includes a through rod 61, a positioning strip 62, and a positioning assembly 63. The through rod 61 is slidably disposed in the central hole and passes through all the translational threaded sleeves 42. The outer end of the through rod 61 extends to the outside of the central hole.

[0060] Multiple positioning strips 62 are provided, each corresponding to a translation screw 41 and fixed to the through rod 61. The positioning strips 62 are used to insert into the corresponding positioning slots 412. The positioning assembly 63 is provided on the frame 1 and connected to the through rod 61. The positioning assembly 63 is used to drive the through rod 61 to slide along the axial direction of the drive shaft 51.

[0061] A positioning groove 412 is formed along the axial direction on the inner wall of the through hole of the translation screw 41. With the positioning strip 62 set on the through rod 61, the through rod 61 is driven by the positioning component 63 to slide along the axial direction of the drive shaft 51. This allows the positioning strip 62 to be inserted into or disengaged from the positioning groove 412 of all translation screws 41, thus completing the circumferential locking or unlocking of all translation screws 41 in one go. The operation is convenient, the synchronization is good, and the locking process time can be shortened.

[0062] The through rod 61 passes through all the translation screw sleeves 42, resulting in a compact structure that makes full use of the internal space of the central hole without increasing the radial dimension of the device, thus ensuring the integrity of the overall structure of the cutter shaft 2.

[0063] The insertion and engagement of the positioning bar 62 and the positioning groove 412 ensures high positioning accuracy. After locking, the circumferential position of the translation screw 41 is stable, which can effectively resist the vibration and torque load generated during the slitting process, maintain the positional accuracy of the tool group 3, and reduce the deviation of the slitting width.

[0064] like Figure 6 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The positioning assembly 63 includes a movable plate 631, a rotating ring 632, and a positioning cylinder 633. The movable plate 631 is slidably mounted on the frame 1, and the sliding direction of the movable plate 631 is parallel to the axial direction of the drive shaft 51.

[0065] A rotating ring 632 is rotatably mounted on a movable plate 631 and fixed to the outer end of a through rod 61. The rotating ring 632 is coaxially mounted with the drive shaft 51. A positioning cylinder 633 is laterally mounted on the frame 1 and connected to the movable plate 631. The positioning cylinder 633 is used to drive the movable plate 631 to slide.

[0066] The movable plate 631 is slidably mounted on the frame 1 along the drive shaft 51, providing stable support and guidance for the through rod 61 and ensuring the straightness of the axial movement of the through rod 61; the rotating ring 632 is rotatably mounted on the movable plate 631 and fixed to the outer end of the through rod 61, so that while the through rod 61 completes axial movement with the movable plate 631, it can also rotate circumferentially with the cutter shaft 2, avoiding interference of the positioning structure with the normal cutting rotation of the cutter shaft 2 and ensuring the normal operation of the slitting operation.

[0067] The positioning cylinder 633 is horizontally positioned and drives the moving plate 631 to slide. It provides direct power output and a fast response speed, enabling rapid locking and unlocking operations and improving the efficiency of distance adjustment. The overall structure is rationally laid out, the moving plate 631 has good sliding guidance, the axial movement of the through rod 61 is smooth, and the positioning action is accurate and reliable, minimizing the risk of jamming or incomplete positioning.

[0068] like Figure 6 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: There are two positioning cylinders 633, which are symmetrically arranged along the axis of the rod 61.

[0069] Two positioning cylinders 633, symmetrically arranged along the axis of the through rod 61, jointly drive the sliding plate 631, ensuring a symmetrical and uniform driving force on the moving plate 631. This alleviates the possibility of the moving plate 631 tilting or jamming during sliding, improves the smoothness and stability of the axial movement of the through rod 61, and also ensures that each positioning strip 62 is inserted into its corresponding positioning groove 412 synchronously. The symmetrically arranged positioning cylinders 633 provide a greater locking thrust, ensuring a tight and reliable connection between the positioning strip 62 and the positioning groove 412. They also distribute the load, reducing the load on a single positioning cylinder 633 and extending its service life.

[0070] like Figure 7 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: Each translation screw 41 has a connecting seat 43 at both ends. The connecting seat 43 includes an outer ring 431, an inner block 432, and a connecting ring 433. The outer ring 431 is coaxially fixed to the inner circumferential surface of the central hole.

[0071] Multiple inner blocks 432 are fixed at intervals on the inner circumferential surface of the outer ring 431, and there is a gap between the inner blocks 432 and the drive shaft 51 for the positioning strip 62 to pass through. The connecting ring 433 is coaxially fixed to the end face of the translation screw 41 and is rotatably connected to the multiple inner blocks 432.

[0072] Connecting seats 43 are provided at both ends of each translation screw 41 for support. The outer ring 431 provides stable radial support for the translation screw 41, ensuring the coaxiality of the translation screw 41 and the cutter shaft 2, alleviating the radial runout that occurs during the rotation of the translation screw 41, and improving the smoothness and accuracy of the thread transmission.

[0073] The connecting ring 433 is coaxially fixed to the end face of the translation screw 41 and rotatably connected to multiple inner blocks 432. This achieves both the circumferential rotational freedom of the translation screw 41 and restricts its axial displacement, ensuring that the translation screw 41 only rotates and does not move with the translation sleeve 42, thus ensuring the stability of the threaded transmission. A gap is left between the inner block 432 and the drive shaft 51, allowing the positioning strip 62 to pass through without interfering with the axial movement of the positioning mechanism 6. The structural layout is reasonable, and the functions of each component do not interfere with each other.

[0074] like Figure 3 and Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The adjusting hole group 21 includes four circumferentially distributed strip holes on the cutter shaft 2; the cutter group 3 includes a cutter holder 31, a cutter disc 32, and four connecting blocks 33.

[0075] The tool holder 31 is coaxially sleeved on the tool shaft 2; the tool disc 32 is coaxially fixed on the tool holder 31; the connecting block 33 corresponds to the strip hole and is slidably connected, and the connecting block 33 is fixed between the tool disc 32 and the translational screw sleeve 42.

[0076] The adjusting hole group 21 uses four circumferentially distributed strip-shaped holes on the cutter shaft 2, which, together with the four connecting blocks 33 on the cutter group 3, ensures uniform force distribution between the cutter group 3 and the translational screw sleeve 42. This makes the sliding process of the cutter group 3 along the cutter shaft 2 smoother, less prone to skewing and jamming, and improves the smoothness of the movement of the cutter group 3. The tool holder 31 is coaxially sleeved on the cutter shaft 2, providing a stable mounting base for the cutter head 32, ensuring the coaxiality of the cutter head 32 and the cutter shaft 2, improving the accuracy of slitting, and facilitating the disassembly and replacement of the cutter head 32.

[0077] The connecting block 33 is slidably connected to the strip hole, which extends along the axial direction of the cutter shaft 2. This not only provides guidance for the movement of the cutter group 3, but also restricts the circumferential rotation of the cutter group 3, allowing the cutter group 3 to rotate with the cutter shaft 2 to perform cutting operations. At the same time, the position can be adjusted along the axial direction. The circumferential torque transmission is reliable, and the axial movement guidance is precise, which can meet both the functional requirements of cutting transmission and pitch adjustment sliding.
