Description

Technical Field

[0001] This utility model belongs to the field of slitting machine technology, and in particular relates to a winding shaft fixing structure for a slitting machine. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide sheets of paper, mica tape, or film into multiple narrow strips. It is commonly used in papermaking machinery, wire and cable manufacturing, and printing and packaging machinery. Slitting machines are primarily used for cutting non-woven fabrics, mica tape, paper, insulating materials, and various film materials. They are particularly suitable for cutting narrow strips. Slitting machines mainly cut large rolls of paper into products of different widths and can also be used to inspect product quality.

[0003] During the operation of the slitting machine, a take-up shaft is needed to rewind the slitting material. Therefore, the take-up shaft needs to be installed on the slitting machine, and a slitting take-up shaft fixing structure is required to install the take-up shaft.

[0004] However, existing take-up shaft fixing structures are generally fixed to the slitting machine with bolts during installation. This means that when the take-up shaft is replaced after use, multiple bolts need to be removed to detach the take-up shaft from the slitting machine, increasing the number of steps for operators and making the disassembly of the take-up shaft inconvenient, thus affecting the working efficiency of the slitting machine. Therefore, a new take-up shaft fixing structure for slitting machines is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a winding shaft fixing structure for a slitting machine, which solves the problem that in the existing winding shaft fixing structure of the slitting machine, when the winding shaft is replaced after use, multiple bolts need to be removed, which makes the winding shaft detach from the slitting machine inconvenient to disassemble, thus affecting the working efficiency of the slitting machine.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a winding shaft fixing structure for a slitting machine, comprising a slitting machine bracket, an mounting plate fixedly connected to the upper surface of the slitting machine bracket, fixing blocks mounted on both sides of the upper surface of the mounting plate, mounting grooves formed on the surface of the fixing blocks, an arc-shaped mounting plate movably connected to the side of the fixing blocks near the mounting groove via a rotating shaft, elastic pads fixedly connected in a circular array inside both the arc-shaped mounting plate and the mounting groove, arc-shaped support plates fixedly connected to the inner sides of both the arc-shaped mounting plate and the mounting groove, a snap-fit ​​block fixedly connected to one side of the arc-shaped mounting plate, an L-shaped plate fixedly connected to the other side of the upper surface of the fixing block near the mounting groove, a rotating rod fixedly connected to the inner side of the L-shaped plate, a telescopic plate movably connected to the surface of the rotating rod, a torsion spring fixedly connected inside the telescopic plate, a snap-fit ​​groove formed on the surface of the fixing block, and a return spring fixedly connected inside the snap-fit ​​groove.

[0008] Furthermore, one of the fixing blocks is fixedly connected to one side of the upper surface of the mounting plate, and a slider is fixedly connected to the lower surface of the other fixing block, with a threaded rod threadedly connected to the surface of the slider.

[0009] Furthermore, a movable groove is provided on the other side of the upper surface of the mounting plate, and the threaded rod is movably connected to the inside of the movable groove through a bearing seat. One end of the threaded rod passes through the mounting plate and is fixedly connected to a crank handle.

[0010] Furthermore, the arc-shaped mounting plate corresponds to the mounting groove, one end of each of the elastic pads is fixedly connected to two arc-shaped support plates, and the telescopic plate corresponds to the snap-fit ​​block.

[0011] Furthermore, the telescopic plate includes a main plate movably connected to the inside of the L-shaped plate via a pivot, an adjusting spring is fixedly connected inside the main plate, and a secondary plate is fixedly connected to one end of the adjusting spring.

[0012] Furthermore, the sub-board is movably connected to the interior of the main board, the sub-board is in contact with the snap-fit ​​block, and the reset spring corresponds to the snap-fit ​​block.

[0013] Furthermore, the two ends of the rotating shaft are fixedly connected to the main board and the rotating rod, respectively, and the snap-fit ​​block corresponds to the snap-fit ​​groove.

[0014] This utility model has the following beneficial effects:

[0015] By incorporating a mounting plate, fixing block, arc-shaped mounting plate, snap-fit ​​block, telescopic plate, and snap-fit ​​groove, the winding shaft is mounted on opposite sides of two arc-shaped support plates. The elastic pads and arc-shaped mounting plates ensure stable installation of the winding shaft. A rotating shaft causes the arc-shaped mounting plate to rotate, and the telescopic plate limits the snap-fit ​​block's position. A return spring and an adjusting spring work together to engage the snap-fit ​​block within the snap-fit ​​groove. When disassembly is required, pushing the two auxiliary plates resets them, and the return spring's force disengages the arc-shaped mounting plate from the snap-fit ​​block, freeing the arc-shaped mounting plate from limiting the winding shaft's position. This makes disassembly of the winding shaft much easier, solving the problem in existing technologies where multiple bolts need to be removed for replacement after use, detaching the winding shaft from the slitting machine and hindering its efficiency.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figures 1-6 As shown, this utility model is a winding shaft fixing structure for a slitting machine, including a slitting machine bracket 1. A mounting plate 2 is fixedly connected to the upper surface of the slitting machine bracket 1. Fixing blocks 3 are installed on both sides of the upper surface of the mounting plate 2. One fixing block 3 is fixedly connected to one side of the upper surface of the mounting plate 2, and a slider 16 is fixedly connected to the lower surface of the other fixing block 3. A threaded rod 12 is threadedly connected to the surface of the slider 16. A movable groove 17 is opened on the other side of the upper surface of the mounting plate 2. The threaded rod 12 is movably connected to the interior of the movable groove 17 through a bearing seat. One end of the threaded rod 12 passes through the mounting plate 2 and is fixedly connected to a crank handle. The threaded rod 12 allows for... Two fixing blocks 3 can accommodate winding shafts of different lengths, making the device more convenient to use. The surface of the fixing block 3 is provided with a mounting groove 4. The side of the fixing block 3 near the mounting groove 4 is movably connected to an arc-shaped mounting plate 5 via a rotating shaft. The arc-shaped mounting plate 5 corresponds to the mounting groove 4. The interior of the arc-shaped mounting plate 5 and the mounting groove 4 are both fixedly connected with elastic pads 6 in a circular array. The inner sides of the arc-shaped mounting plate 5 and the mounting groove 4 are both fixedly connected with arc-shaped support plates 7. Through the cooperation of the elastic pads 6, the arc-shaped mounting plate 5 and the arc-shaped support plate 7, the winding shaft is more stable during use. One end of several elastic pads 6 is fixedly connected to two arc-shaped support plates 7 respectively.

[0029] A snap-fit ​​block 8 is fixedly connected to one side of the arc-shaped mounting plate 5. The winding shaft is installed inside the arc-shaped support plate 7. Through the setting of the rotating shaft, the arc-shaped mounting plate 5 drives the snap-fit ​​block 8 to rotate, so that the snap-fit ​​block 8 is inserted into the inside of the snap-fit ​​groove 13. The telescopic plate 10 corresponds to the snap-fit ​​block 8. An L-shaped plate 9 is fixedly connected to the other side of the upper surface of the fixing block 3 near the mounting groove 4. A rotating rod 14 is fixedly connected to the inner side of the L-shaped plate 9. The surface of the rotating rod 14 is movably connected to the telescopic plate 10. The telescopic plate 10 includes a main plate 1001 movably connected to the inside of the L-shaped plate 9 through a rotating shaft. The two ends of the rotating shaft are fixedly connected to the main plate 1001 and the rotating rod 14 respectively. The inner side of the main plate 1001... An adjusting spring 1002 is fixedly connected to the main body. One end of the adjusting spring 1002 is fixedly connected to a secondary plate 1003. The secondary plate 1003 is movably connected to the inside of the main body 1001. The secondary plate 1003 is in contact with the snap-fit ​​block 8. When the snap-fit ​​block 8 rotates, it will be in contact with the secondary plate 1003, thereby driving the secondary plate 1003 to rotate synchronously. When the snap-fit ​​block 8 is inserted into the inside of the snap-fit ​​groove 13, the tension of the torsion spring 15 causes the secondary plate 1003 to return to its original position, and the lower surface of the secondary plate 1003 is in contact with the snap-fit ​​block 8. Then, the tension of the return spring 11 and the adjusting spring 1002 causes the snap-fit ​​block 8 to snap into the inside of the snap-fit ​​groove 13, thus completing the installation of the winding shaft.

[0030] The telescopic plate 10 is internally fixedly connected to a torsion spring 15. The surface of the fixing block 3 is provided with a snap-fit ​​groove 13. When it is necessary to disassemble the take-up shaft, the sub-plate 1003 is pushed, which compresses the adjusting spring 1002, thereby allowing the sub-plate 1003 to be inserted into the main plate 1001. This causes the sub-plate 1003 to disengage from the snap-fit ​​block 8 and no longer limit the snap-fit ​​block 8. Then, through the elastic force of the return spring 11, the snap-fit ​​block 8 disengages from the snap-fit ​​groove 13, so that the arc-shaped mounting plate 5 no longer limits the take-up shaft. The snap-fit ​​block 8 corresponds to the snap-fit ​​groove 13. The snap-fit ​​groove 13 is internally fixedly connected to a return spring 11, which corresponds to the snap-fit ​​block 8.

[0031] Specifically, the winding shaft fixing structure of this slitting machine is used as follows: The winding shaft is installed inside the arc-shaped support plate 7. Through the setting of the rotating shaft, the arc-shaped mounting plate 5 drives the snap-fit ​​block 8 to rotate, so that the snap-fit ​​block 8 is inserted into the snap-fit ​​groove 13, thereby compressing the return spring 11. When the snap-fit ​​block 8 rotates, it will be in contact with the sub-plate 1003, thereby driving the sub-plate 1003 to rotate synchronously. After the snap-fit ​​block 8 is inserted into the snap-fit ​​groove 13, the elastic force of the torsion spring 15 makes the sub-plate 1003 return to its original position, and the lower surface of the sub-plate 1003 is in contact with the snap-fit ​​block 8. Thus, through the elastic force of the return spring 11 and the adjusting spring 1002, the snap-fit ​​block 8 is snapped into the snap-fit ​​groove 13, completing the installation of the winding shaft. Furthermore, through the cooperation of the elastic pad 6, the arc-shaped mounting plate 5 and the arc-shaped support plate 7, the winding shaft is more stable during use.

[0032] When the take-up shaft needs to be disassembled, push the sub-plate 1003 to compress the adjusting spring 1002, thereby allowing the sub-plate 1003 to insert into the main plate 1001. This disengages the sub-plate 1003 from the locking block 8, eliminating its limiting effect on the locking block 8. The spring force of the reset spring 11 then disengages the locking block 8 from the locking groove 13. Afterward, rotate the arc-shaped mounting plate 5 to rotate the locking block 8, thus removing the arc-shaped mounting plate 5 from limiting the take-up shaft and making the disassembly of the take-up shaft more convenient.
