Description

Technical Field

[0001] The invention relates to the technical field of conveying and winding, and in particular to a winding structure of a slitting machine. Background Art

[0002] As the length of the membrane increases, the core will choose different diameters according to production requirements, equipment configuration and film characteristics, so as to better control the film winding process, reduce waste and improve production efficiency. However, when changing cores of different diameters, the chuck and pressure roller also need to be adjusted accordingly.

[0003] For example, Chinese patent publication number CN112607467A discloses a film production winding device, which includes a base, a long support, a short support, a side support, etc. The base is equipped with a long support, a short support and a side support, the long support is installed in the middle of the bottom plate, the short support is next to the long support, and two side support are symmetrically arranged along the center line of the base. It is equipped with a winding assembly, and the ladder block, spring 1 and pins in the winding assembly can be used to install core barrels of different diameters. After the core barrel is installed, the motor is started, and the motor will drive the entire winding assembly to move, so that the film can be automatically wound.

[0004] This application uses ladder blocks and pins to adapt to core barrels of different diameters, but the ladder blocks and pins are relatively fixed based on the overall position of the side support plates, so that the core needs to be moved left and right relative to the ladder blocks and pins during disassembly and assembly, otherwise the ladder blocks and pins will be inserted into the core and the core cannot be detached. The overall steps are cumbersome and burdensome, and there are certain limitations in use.

[0005] Therefore, it is necessary to provide a slitting machine winding structure to solve the above technical problems. Summary of the invention

[0006] The object of the present invention is to provide a slitting machine winding structure to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, a slitting machine winding structure is designed which can be adapted to winding cores of different diameters and can facilitate the disassembly and assembly of the winding cores.

[0008] Based on the above ideas, the present invention provides the following technical solutions: a slitting machine winding structure, including a bracket, a clamping seat is slidably installed inside the bracket, and a plurality of expansion sleeves for limiting the core are arranged on the clamping seat, a fitting assembly and a moving assembly that is movably fitted with all the expansion sleeves are arranged inside the clamping seat, and a motor for driving the clamping seat to rotate and a driving assembly for driving the clamping seat and the moving assembly to move are arranged on the bracket; starting the driving assembly can first drive the fitting assembly, the clamping seat and the moving assembly to move synchronously, and when the fitting assembly abuts against the end of the core, the fitting assembly can be separated from the driving assembly, so that the driving assembly only drives the moving assembly to move.

[0009] As a further solution of the present invention: the moving assembly includes a plurality of push rods that slide with the clamping seat, the number of the push rods is adapted to and corresponds to the number of expansion sleeves, and a first inclined surface is provided on the opposite end of the push rod and the expansion sleeve, and the other ends of the plurality of push rods are jointly fixed with a circle that movably engages with the driving assembly.

[0010] As a further solution of the present invention: the push rod can slide along the axial direction of the clamp seat, and when the push rod moves in the direction of the expansion sleeve, the expansion sleeve can be driven to move along the radial direction of the clamp seat through the first inclined surface.

[0011] As a further solution of the present invention: the fitting assembly includes a convex rod and a cross rod that slide with the clamp seat, and the opposite sides of the convex rod and the cross rod are provided with a second inclined surface; a first spring is fixedly installed between the surface of the cross rod and the clamp seat.

[0012] As a further solution of the present invention: the protruding rod can slide along the axial direction of the clamp seat, the cross bar can slide along the radial direction of the clamp seat, the end of the protruding rod away from the cross bar extends from one side surface of the clamp seat, the end of the cross bar away from the protruding rod extends from the other side surface of the clamp seat, and the extended end is movably fitted with the driving assembly.

[0013] As a further solution of the present invention: when the protruding rod moves into the clamping seat, the second inclined surface can drive the cross bar to move in a direction away from the circle, and the first spring makes the cross bar have a tendency to move in the direction of the circle.

[0014] As a further solution of the present invention: the driving assembly includes a first cylinder fixedly connected to the bracket, and the output shaft of the first cylinder is fixedly installed with a U-shaped sleeve that movably engages with the circle, and the surface of the U-shaped sleeve away from the first cylinder is against the cross bar.

[0015] As a further solution of the present invention: the length dimension of the push rod along the radial direction of the clamp seat is equal to the length dimension of the expansion sleeve along the radial direction of the clamp seat, and the width dimension of the push rod along the circumferential direction of the clamp seat is equal to the width dimension of the expansion sleeve along the radial direction of the clamp seat.

[0016] As a further solution of the present invention: the outer surface of the clamp seat is provided with a sleeve groove for the expansion sleeve to slide, and the surface of the clamp seat close to the circle is provided with a slide groove for the push rod to slide, and the slide groove is connected to the sleeve groove.

[0017] As a further solution of the present invention: the output shaft of the motor and the clamp seat are assembled in a key shaft type, the motor can drive the clamp seat to rotate, and the clamp seat can reciprocate relative to the motor.

[0018] Compared with the prior art, the beneficial effects of the present invention are: through the cooperation between the clamping seat, the moving assembly, the bonding assembly and the driving assembly, a method is formed in which the clamping seat is first moved out of the bracket and then the expansion sleeve is extended to a limit position. When installing the roll core, the clamping seat can be extended into the roll core without affecting the supporting effect. When disassembling the roll core, the clamping seat can be separated from the roll core to facilitate the removal of the roll core, which can effectively improve the overall efficiency of the roll core disassembly and assembly. Different from the prior art in which the roll core is moved left and right based on a relatively fixed clamping seat, the operating burden of the staff can be effectively reduced.

[0019] At the same time, the surface of the clamping seat installation fitting assembly can be made to abut against the end of the core, providing effective left and right limit for the core, reducing the left and right deviation of the core during winding, and ensuring the reliable quality of winding; and the way the clamping seat moves and abuts against the core makes the winding structure suitable for cores of different lengths; it can also drive several expansion sleeves to open synchronously to limit the core, so as to be suitable for cores of different diameters, thereby significantly improving the user experience and applicability, and making it more practical.

DETAILED DESCRIPTION

[0032] Example 1: Please refer to Figures 1 to 5 The embodiment of the present invention provides a slitting machine winding structure, which is mainly used to realize the rapid replacement of the core and adapt to the cores of different diameters. The structure includes a bracket 1, and a clamping seat 2 is installed inside the bracket 1 in a sliding manner from left to right. The clamping seat 2 is provided with a plurality of expansion sleeves 3 for limiting the core. The clamping seat 2 is provided with a moving component 4 that is movably fitted with all the expansion sleeves 3. In the initial state, the expansion sleeve 3 is flush with the outer surface of the clamping seat 2. When the moving component 4 moves toward the expansion sleeve 3, it can drive the plurality of expansion sleeves 3 to move away from the clamping seat 2 (in an open state). At this time, the plurality of expansion sleeves 3 can contact with the inner wall of the core to achieve limiting.

[0033] Further, such as Figure 2 As shown, a bonding component 5 is also installed inside the clamp seat 2 in a left-right sliding manner. The right side of the bonding component 5 protrudes relative to the right side of the clamp seat 2, and is used to contact the end of the winding core. When the protruding part of the bonding component 5 on the right side contacts the end of the winding core, the bonding component 5 can be retracted into the clamp seat 2; at the same time, the left side of the bonding component 5 also protrudes relative to the left side of the clamp seat 2.

[0034] Furthermore, a motor 7 for driving the clamp seat 2 to rotate is fixedly mounted on the bracket 1. The output shaft of the motor 7 is assembled with the clamp seat 2 in a key shaft type, that is, the motor 7 can drive the clamp seat 2 to rotate, and the clamp seat 2 can translate left and right along the output shaft of the motor 7. At the same time, a driving component 6 for driving the clamp seat 2 and the moving component 4 to move is provided on the bracket 1. When the driving component 6 is started, it can first drive the fitting component 5, the clamp seat 2 and the moving component 4 to move synchronously. At this time, the moving component 4 has not moved relative to the expansion sleeve 3, and then several expansion sleeves 3 have not moved relative to the clamp seat 2. After the clamp seat 2 drives the fitting component 5 to abut against the end of the winding core, the fitting component 5 can shrink into the clamp seat 2 and separate from the driving component 6. At this time, the driving component 6 can only drive the moving component 4 to move. At this time, the moving component 4 can move in the direction of the expansion sleeve 3 and make several expansion sleeves 3 open, thereby realizing effective positioning of the winding core.

[0035] Reference Figure 3 and Figure 4 In this embodiment, preferably: the moving assembly 4 includes a plurality of push rods 402 that are slidably matched with the clamping seat 2, the number of push rods 402 is adapted to the number of expansion sleeves 3 and corresponds one to one, and the push rods 402 and the expansion sleeves 3 are provided with a first inclined surface 403 at the opposite end. When the push rods 402 move toward the expansion sleeve 3, the expansion sleeve 3 can be driven to extend in the radial direction of the clamping seat 2 through the first inclined surface 403. The other ends of the plurality of push rods 402 are fixedly mounted with a circle 401 that is movably engaged with the driving assembly 6. When the motor 7 drives the clamping seat 2 and the push rods 402 to rotate, the circle 401 can rotate based on the driving assembly 6, and at this time, the driving assembly 6 can still drive the circle 401 to move normally left and right.

[0036] Reference Figures 3 to 5 In this embodiment, preferably, the fitting assembly 5 includes a protruding rod 501 and a cross bar 502 that are slidably matched with the clamp seat 2. The protruding rod 501 and the cross bar 502 are designed to be vertical based on the sliding direction of the clamp seat 2, wherein the protruding rod 501 is slidably matched with the clamp seat 2 (axial direction), and the cross bar 502 is slid in the radial direction of the clamp seat 2. The protruding rod 501 and the cross bar 502 are provided with a second inclined surface 504 on the opposite side. When the protruding rod 501 moves to the left, the cross bar 502 can be driven to move in a direction away from the circle 401 through the second inclined surface 504.

[0037] It can be understood that: in the initial state, the right end of the protruding rod 501 protrudes relative to the clamping seat 2, and is used to contact the end of the winding core, and is configured to only move left based on the initial state; when its right end contacts the end, it can be retracted into the clamping seat 2, and then drive the cross bar 502 to move through the second inclined surface 504. In the initial state, the left end of the cross bar 502 is in contact with the driving component 6, and at this time the driving component 6 can drive the clamping seat 2 to move synchronously through the cross bar 502; when the cross bar 502 moves in the direction away from the circle 401, the left end of the cross bar 502 is separated from the driving component 6.

[0038] In the above structure, a first spring 503 is fixedly installed between the surface of the cross bar 502 and the clamp seat 2, and the first spring 503 makes the cross bar 502 have a tendency to move toward the circle 401. Correspondingly, a short groove 201 is provided on the left side of the clamp seat 2 to allow the cross bar 502 to slide in the radial direction and the first spring 503 to be placed.

[0039] Reference Figures 3 to 5In this embodiment, preferably: the driving assembly 6 includes a first cylinder 601 fixedly connected to the bracket 1, and the output shaft of the first cylinder 601 is fixedly installed with a U-shaped sleeve 602 that is movably engaged with the circle 401. The first cylinder 601 drives the circle 401 to translate through the U-shaped sleeve 602 and will not interfere with the rotation of the circle 401; the end of the U-shaped sleeve 602 away from the first cylinder 601 is against the left end of the cross bar 502, and is also used to drive the cross bar 502 to translate.

[0040] When in use, first put the winding core on the clamp seat 2 (or put the winding core and the clamp seat 2 in correspondence with each other), then start the first cylinder 601 to drive the U-shaped sleeve 602 to move. The U-shaped sleeve 602 drives the clamp seat 2 to move right based on the bracket 1 through the cross bar 502 and the protruding rod 501, and drives the top rod 402 to move right based on the bracket 1 through the circle 401. The clamp seat 2 and the top rod 402 are synchronized, and the expansion sleeve 3 and the clamp seat 2 are kept flush. When the protruding rod 501 contacts the end of the winding core, it shrinks into the clamp seat 2. When shrinking, the protruding rod 501 drives the cross bar 502 to translate along the radial direction of the clamp seat 2 through the second inclined surface 504 and separates from the U-shaped sleeve 602 until the surface of the clamp seat 2 where the protruding rod 501 is installed contacts the end of the winding core. Then, the continued movement of the U-shaped sleeve 602 only drives the circle 401 to move rightward, and then drives the top rod 402 to move rightward, and drives the expansion sleeve 3 to move out of the clamp seat 2 and contact the inner wall of the winding core through the first inclined surface 403, so as to effectively limit the winding core. Finally, the motor 7 is started to drive the clamp seat 2 to rotate, and the circle 401 can rotate based on the U-shaped sleeve 602 to keep the expansion sleeve 3 in the moved-out state, thereby ensuring the limiting effect of the winding core.

[0041] It should be noted that: in this embodiment, only the winding structure on one side of the slitting machine is shown, and when in use, both sides cooperate with each other to limit the winding core.

[0042] To sum up, through the cooperation of structures such as the clamping seat 2, the protruding rod 501, the top rod 402 and the U-shaped sleeve 602, the clamping seat 2 is first moved out of the bracket 1 and then the expansion sleeve 3 is extended to a limit position. When installing the roll core, the clamping seat 2 can be extended into the roll core without affecting the supporting effect. When disassembling the roll core, the clamping seat 2 can be separated from the roll core to facilitate the removal of the roll core, which can effectively improve the overall efficiency of disassembly and assembly of the roll core. Different from the prior art in which the roll core is moved left and right based on a relatively fixed clamping seat 2, the operating burden of the staff can be effectively reduced.

[0043] At the same time, the surface of the protruding rod 501 installed on the clamp seat 2 can be abutted against the end of the core, providing effective left and right limit for the core, reducing the left and right deviation of the core during winding, and ensuring the reliable quality of winding; and the way in which the clamp seat 2 moves and abuts against the core makes the winding structure suitable for cores of different lengths; it can also drive several expansion sleeves 3 to open synchronously to limit the core, so as to be suitable for cores of different diameters, thereby significantly improving the user experience and applicability, and making it more practical.

[0044] Example 2: Please refer to Figures 1 to 7 On the basis of the first embodiment, considering the subsequent maintenance and replacement requirements of the expansion sleeve 3, the push rod 402 is improved: at this time, the length dimension of the push rod 402 along the radial direction of the clamp seat 2 is equal to the length dimension of the expansion sleeve 3 along the radial direction of the clamp seat 2, and the width dimension of the push rod 402 along the circumferential direction of the clamp seat 2 is equal to the width dimension of the expansion sleeve 3 along the radial direction of the clamp seat 2, so that the expansion sleeve 3 and the push rod 402 can be completed in and out from the same opening.

[0045] Reference Figure 6 and Figure 7 Correspondingly, the outer surface of the clamp seat 2 is provided with a sleeve groove 202 for the expansion sleeve 3 to slide, and the expansion sleeve 3 can slide along the radial direction of the clamp seat 2 based on the sleeve groove 202; the surface of the clamp seat 2 close to the circle 401 is provided with a slide groove 203 for the push rod 402 to slide, and the slide groove 203 is connected to the sleeve groove 202.

[0046] When in use, through the structure of the clamp seat 2, the protruding rod 501 and the U-shaped sleeve 602, the clamp seat 2 is first moved out of the bracket 1 and then the expansion sleeve 3 is extended to limit the position, which can provide effective limit for the winding cores with different parameters. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that the clamp seat 2 can be moved in the direction away from the first cylinder 601. At this time, the U-shaped sleeve 602 prevents the circle 401 and the top rod 402 from moving, so that the top rod 402 is pulled out of the clamp seat 2. At this time, the expansion sleeve 3 loses its support and can fall on the bottom wall of the sleeve groove 202. Then the clamp seat 2 is turned over so that the slide groove 203 is facing downward, and the expansion sleeve 3 can automatically slide out due to gravity.

[0047] Compared with the first embodiment, the size of the push rod 402 is adapted to the size of the expansion sleeve 3 through the coordination of the sleeve groove 202, the slide groove 203, the expansion sleeve 3 and the push rod 402, so that the expansion sleeve 3 can be removed from the slide groove 203 where the push rod 402 slides, which can effectively reduce the trouble of disassembly and assembly of the expansion sleeve 3 for maintenance and replacement; at the same time, the removal of all push rods 402 from the clamping seat 2 and the removal of all expansion sleeves 3 from the clamping seat 2 can be carried out at the same time, and the synchronous movement can be applied to the installation steps at the same time, which can further reduce the overall disassembly and assembly trouble. The overall solution is combined with the setting of the push rod 402 and the expansion sleeve 3, which is easy to operate and can further improve the user experience, and has stronger applicability.

[0048] Example 3: Please refer to Figures 1 to 10 On the basis of the second embodiment, considering that when the winding core is replaced, the U-shaped sleeve 602 shell drives the top rod 402 to reset so that the expansion sleeve 3 can be separated from the winding core, but the U-shaped sleeve 602 can no longer drive the cross bar 502 to move, so that the resetting of the clamping seat 2 needs to be done manually by the staff, which has certain limitations in use.

[0049] To this end, the push rod 402 is further improved: at this time, the surface of the push rod 402 is provided with a locking component 8 that is movably engaged with the clamp seat 2, and the interior of the clamp seat 2 is provided with a locking groove 204 that is movably engaged with the locking component 8. In the initial state, the push rod 402 has not approached the expansion sleeve 3. At this time, the locking component 8 is engaged in the locking groove 204, and the U-shaped sleeve 602 can normally drive the push rod 402 to move through the circle 401, and the push rod 402 moves synchronously with the clamp seat 2; when the push rod 402 approaches the expansion sleeve 3, the locking component 8 is separated from the locking groove 204.

[0050] The subsequent reverse movement of the U-shaped sleeve 602 can drive the top rod 402 to reset through the circle 401, allowing the locking assembly 8 to be locked in the locking groove 204 again. At this time, the continued reverse movement of the U-shaped sleeve 602 can drive the clamping seat 2 to move synchronously through the locking assembly 8 and the locking groove 204, so that the clamping seat 2 also moves in the reverse direction and the protruding rod 501 can extend from the surface assembly of the clamping seat 2. When the protruding rod 501 extends out, the first spring 503 can drive the cross bar 502 to approach the circle 401, thereby restoring the fitting state with the U-shaped sleeve 602.

[0051] Reference Figure 8 and Fig. 9 In this embodiment, preferably, the engaging assembly 8 includes two wedge blocks 801 that are slidably matched with the top rod 402, and a second spring 802 is fixedly installed between the two wedge blocks 801. Under the action of the second spring 802, the two wedge blocks 801 have a tendency to extend from the top rod 402. Correspondingly, a through hole 404 is opened on the surface of the top rod 402 for the placement of the wedge blocks 801 and the second spring 802.

[0052] The wedge block 801 has two symmetrically intersecting oblique edges, and the two oblique edges of the wedge block 801 are designed in a V shape as a whole, and the slot 204 is also correspondingly V-shaped, so that the wedge block 801 can move along the slot 204 when subjected to force, and then shrink into the push rod 402.

[0053] Further, see Fig.10In this embodiment, preferably: the bracket 1 is provided with a pressure roller 9 and a second cylinder 10 below the clamping seat 2, the pressure roller 9 is used to fit the surface of the raw material when the core is wound; the second cylinder 10 has a cylinder piston rod, and a swing arm 11 fixedly connected to the cylinder piston rod is fixedly installed at the end of the pressure roller 9, and the swing arm 11 is in a vertical state, so that the pressure roller 9 is located directly below the core.

[0054] Among them, a magnetic switch 12 for detecting the length of the cylinder piston rod is provided on the second cylinder 10, and the magnetic switch 12 is electrically connected to the motor 7. The magnetic switch 12 itself and its electrical connection with the motor 7 are existing mature technologies and will not be described in detail here. When the raw material on the core is rolled up to a suitable thickness, the pressure roller 9 drops to the corresponding position, and the pressure roller 9 drives the cylinder piston rod to drop to the corresponding position through the swing arm 11. At this time, the magnetic switch 12 is started to stop the motor 7 from rotating, and then the core stops at a suitable position. Therefore, no matter what parameters of the core are used, after the cylinder piston rod moves to the sensing point of the magnetic switch 12 after contacting the pressure roller 9, the motor 7 can be stopped.

[0055] When in use, through the structures such as the clamp seat 2, the protruding rod 501 and the U-shaped sleeve 602, the clamp seat 2 is first moved out of the bracket 1 and then the expansion sleeve 3 is extended to limit the position, which can provide effective limit for the cores with different parameters; through the structures such as the sleeve groove 202, the slide groove 203 and the top rod 402, the trouble of disassembly and assembly for maintenance and replacement of the expansion sleeve 3 can be effectively reduced. The working process and effect of this part are the same as those in the second embodiment, and will not be repeated here. The difference is that when the U-shaped sleeve 602 moves, it can still drive the clamp seat 2 and the top rod 402 to move synchronously, and then drive the top rod 402 to move while the clamp seat 2 does not move; when the top rod 402 is driven to move alone, because the clamp seat 2 has been against the end of the core, the wedge block 801 can be separated from the slot 204 and moved to the side of the expansion sleeve 3, so that several expansion sleeves 3 are opened to limit the core.

[0056] When the U-shaped sleeve 602 subsequently drives the circle 401 to move in the opposite direction, it can drive the push rod 402 to move synchronously, so that the wedge block 801 is stuck in the slot 204 again. At this time, the U-shaped sleeve 602 moves in the opposite direction again, and the wedge block 801 and the slot 204 can drive the clamp seat 2 to move synchronously, thereby making the push rod 402 and the clamp seat 2 move in the opposite direction synchronously. At this time, the reverse movement of the clamp seat 2 makes the protruding rod 501 gradually extend and reset. Under the action of the first spring 503, the cross bar 502 also begins to reset and resumes fitting with the U-shaped sleeve 602.

[0057] Compared with the second embodiment, through the coordination of the structures such as the push rod 402, the wedge block 801 and the card slot 204, when the push rod 402 is reset to the initial position, it can restore the state of synchronous movement with the clamp seat 2, thereby driving the clamp seat 2 to move in the direction of the motor 7 and automatically move out of the winding core. At this time, only the winding core needs to be moved without moving the clamp seat 2, which can further improve work efficiency and reduce work burden. The overall solution is combined with the setting of the push rod 402, which will not affect the initial synchronous movement of the push rod 402 and the clamp seat 2, and the setting of the wedge block 801 and the card slot 204 is also conducive to the initial movement of the clamp seat 2 driven by the U-shaped sleeve 602, meeting more requirements in actual use.
