Description

Technical Field

[0001] This invention relates to the field of sheet metal cutting equipment technology, and more specifically to a slitting device for stainless steel thin sheets. Background Technology

[0002] Metal sheets are wide and thin metal plates with a thickness between 0.2 mm and 4 mm. According to the rolling process, they can be divided into hot rolling and cold rolling. In the aluminum industry, the standard for thin plates is 0.2 to 6 mm, while the steel industry usually defines them as plates ≤ 3.0 mm. Cold rolling technology can precisely control the thickness to 0.001 mm and achieve multiple grades of surface finish. Hot rolling can produce thin plates of 0.28 mm. Its technical requirements cover thickness accuracy, flatness, surface quality and mechanical properties.

[0003] Stainless steel sheet is one of the common metal sheets. Stainless steel sheet has a smooth surface, high plasticity, and is resistant to corrosion from acid, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust. The production process of stainless steel sheet mainly includes raw material smelting, continuous casting billet, hot-rolled black coil, hot-rolled annealing and pickling, cold rolling, finished product annealing, finishing surface, leveling and slitting, inspection and warehousing, etc. Among them, the leveling and slitting of stainless steel sheet includes: (1) longitudinal slitting: steel coil is longitudinally slitting into customized narrow steel strips, (2) transverse slitting: uncoiling → leveling → fixed length shearing → stacking, and processing into single finished sheet; the slitting of stainless steel sheet requires the use of a slitting device for slitting processing.

[0004] Chinese patent document CN220073418U discloses a precision iron plate cutting and packaging machine, including multiple sets of base blocks. The top of each set of base blocks is fixedly connected to a mounting plate. A winding shaft is rotatably connected between the two sets of mounting plates. Multiple sets of partition plates are fixedly connected to the outer ring of the winding shaft. Multiple sets of upright plates are installed on the top of each set of base blocks. A movable pressure roller is arranged between the upright plates. A fixed roller is also arranged below the movable pressure roller. A fixed plate is also installed on the top of each set of base blocks. A positioning component is arranged between the two sets of fixed plates.

[0005] During processing, firstly, one end of the iron plate is placed above the connecting plate, so that both sides of the iron plate are within the limiting wheels. When the distance between the two sets of limiting wheels does not match the width of the iron plate, the first handwheel can be turned. At this time, the first threaded rod, which is fixedly connected to the first handwheel, begins to rotate. Since the first threaded rod is threadedly connected to the threaded sleeve, the rotation of the first threaded rod can drive the threaded sleeve to move along the length of the first threaded rod, and at the same time drive the sliding block fixedly connected to the top of the threaded sleeve to slide on the connecting plate until the distance between the two sets of limiting wheels matches the width of the iron plate. Then, the two sets of second handwheels are turned, so that the second threaded rod, which is fixedly connected to the second handwheel, begins to rotate. Since the second threaded rod is threadedly connected to the top plate, the second threaded rod can move downwards when rotating. Since the second threaded rod is rotatably connected to the moving block, the second threaded rod can drive the moving block to slide downwards while rotating and moving downwards. At this time, the moving pressure roller moves closer to the fixed roller, and the distance between them is adjusted to suit the thickness of the iron plate. The iron plate is then conveyed forward by the drive device, so that one end of the iron plate enters between the moving pressure roller and the fixed roller. At this point, the fixed plate secures the iron plate, and simultaneously, rotating the second handwheel causes the moving pressure roller to move downwards, thus pressing and fixing the iron plate against the fixed plate on the fixed roller. Because the rubber disc is in contact with the iron plate, the significant friction during movement causes the moving pressure roller and fixed roller to rotate. The cutting blades then begin cutting the iron plate. Finally, the iron plate is cut into four strips by the three sets of cutting blades, and then moved to the winding shaft. One end of the strip is fixed to the winding shaft, and the servo motor is activated to wind up the iron plate.

[0006] In the above-mentioned technology, when winding the slit thin plates, it is usually necessary to first wind one end of multiple thin plates onto the winding shaft, and then wind the thin plates. During the winding process, the thin plates are prone to displacement and loosening, resulting in poor winding effect after the thin plates are slit. Summary of the Invention

[0007] This invention provides a slitting device for stainless steel sheets, aiming to solve the technical problem in the prior art that when winding slit sheets, it is usually necessary to first wind one end of multiple sheets onto a winding roller, and then wind the sheets. During the winding process, the sheets are prone to shifting and loosening, resulting in poor winding effect after slitting.

[0008] A slitting device for stainless steel sheets according to the present invention includes a frame and a take-up roller rotatably connected to the frame. The take-up roller has an installation groove along its length and an opening for the slit sheet to pass through the installation groove. The take-up roller is also equipped with a clamping assembly for clamping or releasing the end of the sheet extending into the installation groove. The clamping assembly includes a first clamping plate fixed in the installation groove and a second clamping plate slidably connected in the installation groove. A gap corresponding to the opening is provided between the first and second clamping plates. The take-up roller is equipped with a control assembly for sliding the second clamping plate away from or towards the first clamping plate. When the control assembly slides the second clamping plate towards the first clamping plate, the gap between the first and second clamping plates decreases, and the end of the slit sheet is clamped on the take-up roller.

[0009] Beneficial effects: During sheet slitting, the sheet is conveyed on the frame and passes under the slitting blade. The slitting blade then cuts the sheet on the unwinding roller into multiple narrow strips. These strips move from the mounting slot opening into the mounting slot and abut against the upper surface of the first clamping plate. The control assembly then moves multiple second clamping plates closer to the multiple first clamping plates. The second and first clamping plates simultaneously clamp and fix the ends of the slid strips, reducing sheet shifting and loosening, and improving the winding effect after slitting. After the strips are fixed, the upper... The take-up roller and the lower take-up roller rotate simultaneously, and then the slit sheet is wound around the take-up roller. When the sheet is fully wound on the take-up roller, the control component drives the second clamping plate to move away from the first clamping plate. The gap between the first clamping plate and the second clamping plate increases, so that the fully wound sheet can be directly removed from the take-up roller along the length direction of the take-up roller, thereby improving the take-up efficiency of the slit sheet. At the same time, when the sheet is wound, the first clamping plate and the second clamping plate no longer fix the end of the sheet. The innermost ring of the slit sheet is pressed against the mounting sleeve, thereby preventing the wound sheet from loosening from the inside.

[0010] Preferably, the take-up roller is fitted with a plurality of mounting sleeves for winding the slit sheet, and the mounting sleeves are also provided with relief grooves. The openings of the relief grooves and the mounting grooves correspond to each other, and the ends of the slit sheet are connected to the clamping assembly through the openings of the relief grooves and the mounting grooves.

[0011] Preferably, the mounting groove is provided with a cutting assembly for cutting the thin plate clamped in the mounting groove; the cutting assembly includes an arc-shaped cutter rotatably connected to the inner wall of the mounting groove and a rotating rod fixed to the arc-shaped cutter, the rotating rod being rotatably connected to the take-up roller and extending out of the end face of the take-up roller.

[0012] Beneficial effects: After the thin sheet is fully wound on the mounting sleeve, the rotating rod drives the arc-shaped cutter to rotate. During the rotation of the arc-shaped cutter, the thin sheet that is stretched in the mounting groove will be cut. Part of the cut thin sheet is between the first clamping plate and the second clamping plate, forming waste material. The other part extends out through the opening of the mounting sleeve and is located in the inner circle of the mounting sleeve. This can reduce the length of the thin sheet in the inner circle of the mounting sleeve. During subsequent winding, the waste material in the mounting groove needs to be cleaned first, and then the end of the thin sheet is placed in the mounting groove.

[0013] Preferably, the take-up roller is provided with a plurality of limiting blocks for limiting the position of the mounting sleeve. The mounting sleeve is disposed between two adjacent limiting blocks. The limiting blocks slide in a direction perpendicular to the axis of the take-up roller. A push spring is provided inside the take-up roller for driving the limiting blocks to move outward from the take-up roller. One end of the push spring is fixed to the take-up roller, and the other end is fixed to the limiting block. A push assembly is provided on the take-up roller for pulling the limiting blocks extending out of the take-up roller to move inward from the take-up roller.

[0014] Beneficial effects: When multiple mounting sleeves are fitted onto the take-up roller, the spring drives the limiting block to move outward, so that the limiting block extends out of the surface of the take-up roller, thereby limiting the mounting sleeve; in addition, since the mounting sleeve is set between two adjacent limiting blocks, the limiting block can limit the thin plate wound on the mounting sleeve, reduce the deviation of the wound thin plate, and make the thin plate wound on the mounting sleeve more neat.

[0015] Preferably, the control assembly includes a control disk rotatably connected to the take-up roller and a control rod fixed to the control disk. The control rod is fixedly mounted on the second clamping plate, and a fixing assembly for fixing the position of the control disk is provided on the take-up roller.

[0016] Beneficial effects: When the position of the second clamping plate needs to be adjusted, the fixing component is no longer fixed to the position of the control disk. Then, the control disk is rotated, which drives the control lever to rotate. The control lever pushes the second clamping plate to move closer to the first clamping plate, thereby fixing the end of the thin plate between the first and second clamping plates. After the second and first clamping plates fix the thin plate, the position of the control disk is fixed by the fixing component, which can prevent the second clamping plate from moving away from the first clamping plate when the take-up roller rotates. This makes the end of the thin plate more stable when the take-up roller rotates.

[0017] Preferably, the fixing component includes a movable rod slidably connected to the take-up roller, a fixing block fixed to the movable rod, and fixing grooves formed on the take-up roller and the control panel. Both the fixing block and the fixing groove are polygonal. When the fixing block is simultaneously located in the fixing grooves on the take-up roller and the control panel, the position of the control panel is fixed.

[0018] Preferably, the first clamping plate is provided with a clamping spring for pushing the second clamping plate to move away from the first clamping plate, one end of the clamping spring is fixed to the first clamping plate and the other end is fixed to the second clamping plate.

[0019] Beneficial effects: When the control panel is not rotating, the clamping spring pushes the second clamping plate to move away from the first clamping plate. At this time, the gap between the first and second clamping plates is the largest. Then, when the cut end of the thin plate is placed between the first and second clamping plates, the control component drives the second clamping plate to move closer to the first clamping plate, thereby fixing the end of the thin plate. After the full roll is wound and the full roll of thin plate is removed from the take-up roller, the fixing block and the fixing groove on the take-up roller separate. Under the action of the clamping spring, the second clamping plate is automatically pushed to move away from the first clamping plate, which facilitates the clamping of the end of the subsequent thin plate.

[0020] Preferably, the pushing assembly includes a connecting rod fixed to the limiting block and an arc-shaped pushing strip rotatably connected to the take-up roller. The connecting rod is used to connect multiple limiting blocks, and the arc-shaped pushing strip is provided with a pushing surface for abutting against the connecting rod. The pushing surface gradually tilts away from the inner wall of the take-up roller in the direction away from the connecting rod.

[0021] Preferably, limit rings are fixedly installed at both ends of the movable rod, and the cross-section of the limit ring in the vertical direction is larger than the cross-section of the fixed block in the vertical direction.

[0022] Preferably, the take-up roller is provided with a support spring for supporting the rotating rod. One end of the support spring is fixed to the take-up roller and the other end is fixed to the rotating rod. When cutting the clamped thin plate, the support spring is in a compressed state.

[0023] Beneficial effects: The support spring pushes the rotating rod and the arc-shaped cutter fixed on the rotating rod to rotate away from the first clamping plate. After the thin plate on the mounting sleeve is fully wound, the operator rotates the rotating rod, which in turn drives the arc-shaped cutter to rotate. During the rotation, the clamped thin plate is cut. After the cutting is completed, the operator releases the rotating rod, and under the action of the support spring, the arc-shaped cutter rotates in the opposite direction to the initial position, which facilitates the cutting of subsequent thin plates.

[0024] The beneficial effects of this invention are as follows: With the clamping and control components in place, the thin sheet moves from the mounting slot opening into the mounting slot and abuts against the upper surface of the first clamping plate. Then, the control component drives multiple second clamping plates to move closer to the multiple first clamping plates. The second and first clamping plates simultaneously clamp and fix the ends of the multiple thin sheets after slitting, reducing the phenomenon of thin sheet displacement and loosening, and improving the winding effect of the thin sheet after slitting. After the thin sheet is fixed, the upper and lower winding rollers rotate simultaneously, and then the slitting thin sheet is wound around the winding roller. When the thin sheet on the winding roller is fully wound, the control component drives the second clamping plates to move away from the first clamping plates. The gap between the first and second clamping plates increases, so that the fully wound thin sheet can be directly removed from the winding roller along the length direction of the winding roller, thereby improving the winding efficiency of the slitting thin sheet.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] Reference Figures 1-7 The present invention discloses a slitting device for stainless steel sheets, comprising a frame 01, on which an unwinding roller (not shown), a slitting blade 02, and a take-up roller 03 are mounted. The slitting blade 02 cuts the sheet on the unwinding roller, and the slit sheet is wound around the take-up roller 03. The take-up roller 03 is detachably connected to a motor (not shown) on the frame 01, and the motor drives the take-up roller 03 to rotate. In this embodiment, after the sheet wound on the take-up roller 03 is fully wound, the take-up roller 03 is removed from the frame 01. A thin sheet is fully wound onto the take-up roller 03, and the take-up roller 03 is separated from the motor. The fully wound thin sheet is then removed, and the thin sheet is rewound onto the take-up roller 03. The take-up roller 03 is equipped with a clamping assembly 1 for fixing the ends of the cut thin sheet, and a cutting assembly 2 for cutting the thin sheet clamped by the clamping assembly 1. After the thin sheet is fully wound onto the take-up roller 03, the thin sheet fixed on the clamping assembly 1 is cut by the cutting assembly 2, thereby conveniently removing the fully wound thin sheet from the take-up roller 03.

[0035] Reference Figure 1 A limiting component 7 is provided on the frame 01. The limiting component 7 includes a limiting roller 71 and a lifting frame 72. The limiting roller 71 is rotatably engaged with the lifting frame 72. The limiting roller 71 is used to abut and limit the outermost layer of the wound sheet. The lifting frame 72 is installed on the frame 01 and is used to drive the limiting roller 71 to move up and down vertically. When the lifting frame 72 descends, it drives the limiting roller 71 to abut the top of the outermost layer of the wound sheet. As the sheet is gradually wound up, the lifting frame 72 drives the limiting roller 71 to rise synchronously.

[0036] Reference Figures 1 to 5An installation groove 04 is provided on the take-up roller 03, which is opened along the length direction of the take-up roller 03. An opening 05 is provided on the take-up roller 03, which is also opened along the length direction of the take-up roller 03. The opening 05 on the take-up roller 03 is connected to the installation groove 04, making the cross-section of the installation groove 04 C-shaped. The clamping assembly 1 is disposed in the installation groove 04. At the same time, an installation sleeve 06 for winding the slit thin plate is sleeved on the take-up roller 03. A relief groove 07 is provided on the installation sleeve 06, which is opened along the length direction of the installation sleeve 06. Under the action of the relief groove 07, the cross-section of the installation sleeve 06 is C-shaped. In this embodiment, the relief groove 07 on the installation sleeve 06 corresponds to the opening 05 on the installation groove 04, which facilitates the connection between the end of the slit thin plate and the clamping assembly 1 through the relief groove 07 and the opening 05 of the installation groove 04, thereby achieving the purpose of fixing the end of the thin plate.

[0037] Reference Figures 1 to 5 The clamping assembly 1 includes a first clamping plate 11 fixed to the inner wall of the mounting groove 04 and a second clamping plate 12 slidably connected to the take-up roller 03. A clamping spring 13 is fixedly installed on the first clamping plate 11, with one end of the clamping spring 13 away from the first clamping plate 11 fixed to the second clamping plate 12. The clamping spring 13 is used to push the second clamping plate 12 to move away from the first clamping plate 11. A gap is left between the first clamping plate 11 and the second clamping plate 12 for placing the end of the thin plate. A control assembly 3 is provided on the take-up roller 03 to drive the second clamping plate 12 to move closer to the first clamping plate 11, clamping and fixing the end of the thin plate placed on the first clamping plate 11. In this embodiment, a stop block 51 is fixedly installed on the first clamping plate 11. When clamping the cut thin plate, the end of the thin plate can abut against the stop block 51, so that the length of the thin plate extending into the mounting groove 04 is the same.

[0038] After the thin plates are cut, the ends extend into the mounting groove 04 through the relief groove 07 and the opening 05 on the take-up roller 03, and then abut against the upper surface of the first clamping plate 11. After the ends of multiple thin plates on the same take-up roller 03 are installed, the control component 3 drives the second clamping plate 12 to move closer to the first clamping plate 11. At this time, the first clamping plate 11 and the second clamping plate 12 clamp the ends of the thin plates, and the clamping spring 13 is compressed. After the ends of the thin plates are clamped, the unwinding roller, the slitting knife 02 and the take-up roller 03 work simultaneously. The cut thin plates are wound around the mounting sleeve 06 on the take-up roller 03. At this time, the take-up roller 03 drives the mounting sleeve 06 to rotate and wind up the cut thin plates. After the thin plates on the mounting sleeve 06 are fully wound, the outermost ring of the thin plates is fixed by adhesive bonding, which can reduce the loosening of the wound thin plates.

[0039] Reference Figures 1 to 5After the thin plate on the mounting sleeve 06 is fully wound, the thin plate fixed by the first clamping plate 11 and the second clamping plate 12 is cut by the cutting assembly 2. After cutting, the length of the thin plate left in the inner circle of the mounting sleeve 06 can be reduced. In addition, since the cut thin plate is wound on the mounting sleeve 06, the mounting sleeve 06 can limit the innermost thin plate and prevent the inner circle of the thin plate from becoming loose after winding. In other embodiments, the mounting sleeve 06 may not be provided on the take-up roller 03, so that the cut thin plate is directly wound on the take-up roller 03. After the full winding is completed, after removing it from the take-up roller 03, the innermost thin plate still needs to be limited (for example, by bonding). After cutting, waste material will remain between the first clamping plate 11 and the second clamping plate 12. Then, the second clamping plate 12 moves away from the first clamping plate 11, and at the same time, the opening 05 of the mounting groove 04 faces downward. Under the action of gravity, the waste material is separated from the first clamping plate 11 and the second clamping plate 12, which facilitates the subsequent clamping of the slit sheet.

[0040] Reference Figures 1 to 5 The control assembly 3 includes a control disk 31 rotatably connected to the take-up roller 03 and a control rod 32 fixed to the second clamping plate 12. The control disk 31 and the take-up roller 03 are coaxially arranged. An arc-shaped clearance hole (not shown in the figure) is provided at one end of the take-up roller 03. When the control disk 31 rotates, the control rod 32 slides in the arc-shaped clearance hole. At the same time, the control rod 32 is fixedly installed on the control disk 31. In the initial state, the position of the control disk 31 is not fixed, and the clamping spring 13 will push the second clamping plate 12 away from the first clamping plate 11. At this time, a space is formed between the second clamping plate 12 and the first clamping plate 11 for... When the end of the thin plate is placed between the second clamping plate 12 and the first clamping plate 11, the gap between the ends of the thin plate is adjusted. At this time, the second clamping plate 12 needs to be moved closer to the first clamping plate 11. The control disk 31 is rotated clockwise, which drives the control rod 32 to rotate. The control rod 32 slides in the arc-shaped clearance hole. During the rotation of the control rod 32, the second clamping plate 12 will be moved closer to the first clamping plate 11. At this time, the gap between the first clamping plate 11 and the second clamping plate 12 becomes smaller, and the clamping spring 13 is compressed, which makes it easier to fix the end of the thin plate after cutting.

[0041] Reference Figures 2 to 6A fixing component 4 is provided on the take-up roller 03. The fixing component 4 is used to fix the position of the rotating control disk 31. The fixing component 4 includes a moving rod 41, a fixing block 42, and a fixing groove 43. The moving rod 41 slides on the take-up roller 03, and the fixing block 42 is fixed on the moving rod 41. The control disk 31 has a fixing groove 43, and the take-up roller 03 also has a fixing groove 43. Both the fixing block 42 and the fixing groove 43 are polygonal. In this embodiment, the cross-section of the fixing block 42 and the fixing groove 43 are both hexagonal. Limiting rings 44 are provided at both ends of the moving rod 41. The cross-section of the limiting rings 44 is larger than the cross-section of the fixing block 42. During the sliding process of the moving rod 41, it can prevent the moving rod 41 from disengaging from the fixing groove 43.

[0042] Reference Figures 2 to 6 When the fixed block 42 is simultaneously located in the fixed groove 43 on the control disk 31 and the fixed groove 43 on the take-up roller 03, the control disk 31 cannot rotate relative to the take-up roller 03, and the position of the second clamping plate 12 is fixed. When it is necessary to rotate the control disk 31, pull the moving rod 41 to disengage the fixed block 42 from the fixed groove 43 on the take-up roller 03, so that the fixed block 42 is only located in the fixed groove 43 on the control disk 31. Then rotate the moving rod 41, which drives the fixed block 42 to rotate. The fixed block 42 drives the control disk 31 to rotate, thereby driving the control rod 32 to move and adjust the position of the second clamping plate 12. After the position of the second clamping plate 12 is adjusted, push the moving rod 41 in the opposite direction so that the fixed block 42 on the moving rod 41 is simultaneously located in the fixed groove 43 on the take-up roller 03 and the fixed groove 43 on the control disk 31.

[0043] Reference Figures 2 to 6 The cutting assembly 2 includes an arc-shaped cutter 21 and a rotating rod 22. The arc-shaped cutter 21 is slidably connected to the inner wall of the mounting groove 04 and can rotate along the axis of the take-up roller 03. The arc-shaped cutter 21 is arranged along the length direction of the take-up roller 03. The rotating rod 22 is fixedly installed on the side of the arc-shaped cutter 21, and one end of the rotating rod 22 extends out of the side of the take-up roller 03. After the thin plate on the mounting sleeve 06 is fully wound, the take-up roller 03 stops rotating. Then, the operator rotates the rotating rod 22, which drives the arc-shaped cutter 21 to rotate, and the rotating arc-shaped cutter 21 cuts the clamped thin plate. In this embodiment, during cutting, the arc-shaped cutter 21 abuts against the surface of the first clamping plate 11, and the first clamping plate 11 is provided with a receiving groove to accommodate the arc-shaped cutter 21, thereby improving the cutting effect of the thin plate.

[0044] Reference Figures 2 to 6To support the position of the arc-shaped cutter 21, a support spring 23 is fixedly installed on the end face of the take-up roller 03. One end of the support spring 23 is fixed to the take-up roller 03, and the other end is fixed to the rotating rod 22. Under the action of the support spring 23, the rotating rod 22 drives the arc-shaped cutter 21 to rotate away from the first clamping plate 11. When it is necessary to cut the pressed thin plate, the rotating rod 22 is pushed to rotate around the axis of the take-up roller 03, so that the arc-shaped cutter 21 moves closer to the first clamping plate 11. The support spring 23 is gradually compressed. After the thin plate is cut, the rotating rod 22 is released. Under the action of the support spring 23, the rotating rod 22 and the arc-shaped cutter 21 rotate in opposite directions and finally rotate back to the initial position, which facilitates the subsequent cutting of the thin plate.

[0045] Reference Figures 3 to 7 A limiting block 5 is provided on the take-up roller 03 to limit the position of the mounting sleeve 06. Multiple limiting blocks 5 are provided and spaced apart along the length direction of the take-up roller 03. The mounting sleeve 06 is located between two adjacent limiting blocks 5. The limiting blocks 5 slide radially on the take-up roller 03. When it is necessary to place the mounting sleeve 06 on the take-up roller 03 or remove the fully wound mounting sleeve 06 from the take-up roller 03, the limiting block 5 is completely inside the take-up roller 03 before the mounting sleeve 06 is installed or removed from the take-up roller 03.

[0046] Reference Figures 3 to 7 A pushing assembly 6 is provided on the take-up roller 03. The pushing assembly 6 is used to push the limiting blocks 5 to move closer to the axis of the take-up roller 03. The pushing assembly 6 includes a connecting rod 61 slidably connected to the take-up roller 03 and an arc-shaped pushing strip 62 rotatably connected to the take-up roller 03. The connecting rod 61 is used to connect multiple limiting blocks 5, so that multiple limiting blocks 5 slide simultaneously on the take-up roller 03. The arc-shaped pushing strip 62 has a pushing surface 63, which abuts against the connecting rod 61. The pushing surface 63 gradually moves away from the connecting rod 61. Inclined away from the inner wall of the take-up roller 03, the cross section of the arc-shaped push bar 62 gradually increases in the direction away from the connecting rod 61 under the action of the push surface 63. At the same time, multiple push springs 64 are fixedly installed on the connecting rod 61. The end of the push spring 64 away from the connecting rod 61 is fixed to the inner wall of the take-up roller 03. The push spring 64 is used to push the limiting block 5 out of the take-up roller 03. The limiting block 5 that extends out of the take-up roller 03 is used to limit the position of the mounting sleeve 06. At the same time, the position of the thin plate can be limited when the thin plate is wound.

[0047] When it is necessary to move the limiting block 5 into the take-up roller 03, rotate the arc-shaped push bar 62 counterclockwise. As the pushing surface 63 gradually tilts away from the inner wall of the mounting groove 04 in the direction away from the connecting rod 61, the arc-shaped push bar 62 will push the connecting rod 61 to move closer to the axis of the take-up roller 03. During the movement, it will drive the limiting block 5 to move, and then move the limiting block 5 into the take-up roller 03. At the same time, the push spring 64 is in a compressed state. After the mounting sleeve 06 is removed or installed, rotate the arc-shaped push bar 62 clockwise. Then, under the action of the push spring 64, it will drive the connecting rod 61 and the limiting block 5 to move in the opposite direction. At this time, the limiting block 5 will extend out of the surface of the take-up roller 03 and limit the mounting sleeve 06.

[0048] Reference Figures 3 to 7 To facilitate the movement of the connecting rod 61, an arc-shaped surface 52 is provided on the connecting rod 61. At this time, the contact area between the connecting rod 61 and the arc-shaped push bar 62 becomes larger, making the movement of the connecting rod 61 more stable. Meanwhile, to facilitate the rotation of the arc-shaped push bar 62, a push rod 53 is fixedly installed on the side of the arc-shaped push bar 62. The push rod 53 is rotatably connected to the take-up roller 03, and one end of the push rod 53 extends out of the end face of the take-up roller 03.

[0049] The implementation principle of the slitting device for stainless steel sheet of the present invention is as follows: the sheet to be slitting is placed on the unwinding roller, the sheet is conveyed on the frame 01, and when it is conveyed to the slitting blade 02, the sheet is cut by the slitting blade 02. The end of the slitting sheet enters the gap between the first clamping plate 11 and the second clamping plate 12 through the opening 05 of the relief groove 07 and the mounting groove 04, and abuts against the first clamping plate 11. Then the control disk 31 drives the second clamping plate 12 to move closer to the first clamping plate 11. At this time, the end of the sheet is clamped and fixed by the first clamping plate 11 and the second clamping plate 12. Next, the unwinding roller, slitting blade 02, and take-up roller 03 work simultaneously. The slit sheet is wound around the mounting sleeve 06 on the take-up roller 03. The take-up roller 03 drives the mounting sleeve 06 to rotate and wind up the slit sheet. After the sheet on the mounting sleeve 06 is fully wound, the outermost ring of the sheet is fixed by adhesive bonding. The sheet fixed by the first clamping plate 11 and the second clamping plate 12 is cut by the cutting assembly 2. After cutting, the length of the sheet left in the inner ring of the mounting sleeve 06 can be reduced. In addition, since the slit sheet is wound around the mounting sleeve 06, the mounting sleeve 06 can limit the innermost sheet to prevent the inner ring of the sheet from becoming loose after winding.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
