DETAILED DESCRIPTION

[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1: Figure 1 - Figure 10The figure shows a metal coil longitudinal slitting machine, comprising a base 1 and a fixed frame 11 arranged on the base 1, two shearing rollers 2 are rotatably arranged on the fixed frame 11, one of the shearing rollers 2 is connected to a driving motor, a gear set 12 is arranged between the shearing rollers 2, the gear set 12 comprises a linkage gear fixed on the shearing roller 2, and two connecting gears rotatably mounted on the connecting rod and meshing with the linkage gear, the two connecting gears mesh with each other for transmission, the connecting rod is connected to the bracket, and the bracket is mounted on the base 1, and the reverse rotation of the two shearing rollers 2 is achieved by the cooperation of the linkage gear and the connecting gear, a driving frame 10 is slidably arranged on the base 1, the driving frame 10 is threadedly connected to a screw rod 102, the screw rod 102 is rotatably arranged in the base 1, and the base 1 is driven by a moving motor to drive the screw rod to make the driving frame 10 move on the base 1, two receiving grooves 101 are provided on the driving frame 10, the shearing roller 2 is embedded in the receiving groove 101, a plurality of cutter discs 3 are sleeved on the shearing roller 2, and an embedding block 31 is provided on the cutter disc 3, and the shearing roller 2 is provided with a plurality of cutter discs 3. When the shearing roller 2 is in working order, the two shearing rollers 2 on the fixed frame 11 on the base 1 are rotated in the opposite direction by means of the gear set 12. The ends of the shearing rollers 2 are embedded in the receiving groove 101 on the frame 10 to support the shearing roller 2. The multiple cutter discs 3 arranged at intervals of preset width on the shearing roller 2 form a shearing edge. When the coil passes through, the rotating cutter disc 3 applies a shearing force to cut it into multiple narrow strips at one time. By operating the pull rod 4, the lifting plate 5 can be driven up and down by the adjusting mechanism 7 to limit or release the cutter disc 3. There is no need to disassemble the cutter disc 3 and the spacer sleeve at all, which fundamentally simplifies the adjustment process of the slitting width, not only saves a lot of time, but also reduces labor costs, making the operation of the equipment more efficient and convenient.

[0020] like Figure 6 and Figure 9As shown, the adjustment mechanism 7 includes a plurality of rotating rings 71, which are rotatably mounted on the pull rod 4. T-shaped rods 73 are fixedly mounted on the rotating rings 71. Mounting plates 72 are fixedly mounted on both sides of the lifting plate 5. The mounting plates 72 are provided with inclined slots 721. The ends of the T-shaped rods 73 slide in the inclined slots 721. When the pull rod 4 moves linearly, the rotating rings 71 will move synchronously with it. At this time, the T-shaped rods 73 slide in the inclined slots 721. This sliding method can smoothly and accurately convert the linear motion of the pull rod 4 into the lifting motion of the lifting plate 5. This conversion method is not only highly accurate, but also has a stable motion process, ensuring the smoothness of the lifting plate 5 during the ascent or descent process, thereby ensuring that the limiter 6 can accurately limit or release the embedded block 31 of the cutter disc 3, providing reliable power transmission for the position adjustment of the cutter disc 3.

[0021] like Figure 3 、 Figure 5 and Figure 7 As shown, a mounting cavity 22 is provided in the shear roller 2, and an embedding groove 21 and a through groove 23 are provided on the shear roller 2, which are connected to the mounting cavity 22. An embedding block 31 is slidably set in the embedding groove 21. A scale mark is provided on one side of the embedding groove 21 to locate the position of the cutter disc 3. The pull rod 4 is slidably set in the through groove 23. The mounting cavity 22 provides a closed and stable installation space for internal components such as the lifting plate 5 and the limiter 6, ensuring that these components will not be interfered with by external factors during operation and can operate normally. When the cutter disc 3 moves, the embedding groove 21 plays a strict guiding role for the sliding of the embedding block 31, ensuring that the cutter disc 3 can only move in the set direction without deviation, thereby ensuring the stability of the cutter disc 3 when moving. At the same time, when the shear roller 2 is working, the cutter disc 3 can rotate synchronously with the shear roller 2. The through groove 23 provides a guide path for the sliding of the pull rod 4, so that the operating force of the pull rod 4 can be effectively transmitted to the internal adjustment mechanism 7 and other components.

[0022] like Figure 8 As shown, the limiting member 6 includes limiting blocks 61. Adjacent limiting blocks 61 can clamp the embedded blocks 31. A trapezoidal block 62 is fixedly provided on the upper end of the limiting block 61, and a sliding ear 63 is provided on the lower end of the limiting block 61. When the lifting plate 5 rises, the limiting blocks 61 will be located on both sides of the cutter disc 3. By clamping the embedded blocks 31 by the adjacent limiting blocks 61, the position of the cutter disc 3 is fixed, ensuring that the cutter disc 3 does not move during the slitting process, ensuring the stability of the slitting operation. The inclined surface design of the trapezoidal block 62 allows the embedded block 31 to press the inclined surface of the trapezoidal block 62 in the direction of movement, which can easily make the limiting block 61 slide on the lifting plate 5, allowing the cutter disc 3 to move along the embedded groove 21 under the action of external force. The sliding ear 63 provides stable support for the upward and downward sliding of the limiting member 6.

[0023] like Figure 7 - Figure 8 As shown, the lifting plate 5 is provided with side plates 51 on both sides, and two slide grooves 511 are defined on the side plates 51. Guide rods 512 are provided on both sides of the mounting cavity 22. The guide rods 512 extend through the side plates 51 through the slide grooves 511. The lifting plate 5 is provided with multiple vertical rods 52. The sliding ears 63 are slidably disposed on the vertical rods 52. The vertical rods 52 are provided with springs 53. The ends of the springs 53 are respectively connected to the lifting plate 5 and the sliding ears 63. During the lifting process of the lifting plate 5, the cooperation between the guide rods 512 and the slide grooves 511 plays a guiding and limiting role, limiting the movement trajectory of the lifting plate 5 so that it can only move up and down along the direction of the guide rods 512. This ensures the accuracy of the movement trajectory and avoids the problem of the limiter 6 not being able to accurately limit the position due to the deviation of the lifting plate 5. The vertical rods 52 provide a path for the sliding ears 63 to slide, ensuring that the limiter 6 can only slide up and down. When the embedded block 31 is separated from the trapezoidal block 62, the spring 1 53 will reset under the action of its own elastic force, driving the limiter 6 to move upward and reset, thereby preliminarily limiting the embedded block 31 in time, improving the stability of the cutter disc 3 after adjustment, and laying the foundation for subsequent fixing work.

[0024] like Figure 9 As shown, the pull rod 4 is slidably set on the shear roller 2 through the through groove 23, and a rotating sleeve 9 is rotatably set on the installation cavity 22. The rotating sleeve 9 is sleeved on the pull rod 4, and a spring 92 is set between the rotating sleeve 9 and the pull rod 4. A protrusion 41 is fixedly set on the pull rod 4, and a handle 43 is fixedly set at one end of the pull rod 4. A transverse groove 42 is arranged in an array on the pull rod 4, and a sliding column 91 is arranged in an array inside the rotating sleeve 9. The sliding column 91 is slidably set in the transverse groove 42. The setting of the handle 43 provides a convenient operating point for the operator, allowing the operator to easily rotate or push and pull the pull rod 4. When the pull rod 4 slides axially, the sliding column 91 slides in the transverse groove 42. The cooperation of the transverse groove 42 and the sliding column 91 enables the rotating sleeve 9 to rotate synchronously with the pull rod 4 without affecting the axial sliding of the pull rod 4.

[0025] like Figure 10As shown, a limiting sleeve 8 is fixedly provided on the mounting cavity 22. The limiting sleeve 8 is mounted on the pull rod 4. The limiting sleeve 8 has an E-shaped groove 81 formed thereon. The E-shaped groove 81 consists of a movable groove 811 and three limiting grooves 812 vertically connected thereto. When the protruding rod 41 is respectively inserted into different limiting grooves 812, the lifting plate 5 corresponds to different heights. When the axial position of the pull rod 4 needs to be adjusted, the movable groove 811 allows the protruding rod 41 to freely move along the axial direction of the pull rod 4, providing space for adjusting the position of the pull rod 4. After the pull rod 4 is adjusted to the desired position, the pull rod 4 is rotated to insert the protruding rod 41 into the corresponding limiting groove 812, thereby firmly limiting the protruding rod 41 and fixing the position of the pull rod 4. Through the above operations, the lifting plate 5 can be stably in different positions such as the middle, rising or falling. At the same time, when the spring 2 92 is not charged, the protruding rod 41 is located in the limit groove 812 in the middle of the movable groove 811, so that the user can quickly turn the protruding rod 41 into the limit groove 812, and when pushing and pulling the pull rod 4, the spring 2 92 can be charged. When the push-pull pull rod 4 is to the extreme position, the protruding rod 41 can be quickly embedded in the corresponding limit groove 812. When the shearing roller 2 is working, the protruding rod 41 is firmly restricted in the limit groove 812 under the action of centrifugal force, and will not accidentally fall out, thereby ensuring the reliability and speed of the adjustment and fixing process of the knife disc 3, significantly improving the accuracy of the equipment operation, and ensuring the smooth progress of the cutting work.

[0026] It should be noted that when the metal coil longitudinal shearing and slitting machine adjusts the spacing between the blade discs 3, the pull rod 4 is pulled by the handle 43, the rotating ring 71 in the adjustment mechanism 7 moves with the pull rod 4, and the T-shaped rod 73 slides in the inclined groove 721 of the mounting plate 72, thereby driving the lifting plate 5 to slide downward along the slide groove 511 in the mounting cavity 22 of the shearing roller 2 through the guide rod 512, and then the pull rod 4 is rotated to embed the protruding rod 41 into the middle limit groove 812, and the lifting plate 5 is at an intermediate height. At this time, the embedded block 31 on the cutter disc 3 is at the same height as the trapezoidal block 62 of the limiting member 6. When the cutter disc 3 is moved, the embedded block 31 slides in the embedded groove 21, which will squeeze the inclined surface of the trapezoidal block 62 in the moving direction, so that the limiting block 61 slides downward on the vertical rod 52 through the sliding ear 63 and accumulates force on the spring 1 53 to realize the movement of the cutter disc 3. When the embedded block 31 is separated from the trapezoidal block 62, the limiting member 6 moves upward and resets under the resetting action of the spring 1 53, and at the same time, the trapezoidal blocks 62 on both sides of the embedded block 31 preliminarily limit it. When multiple cutter discs 3 are adjusted to the specified position, push the pull rod 4 and drive the lifting plate 5 to rise through the adjustment mechanism 7 until the limit blocks 61 are located on both sides of the embedded block 31, fixing the position of the cutter disc 3. The cutter disc 3 with adjusted spacing in the middle of the shear roller 2 can then be used for longitudinal shearing, and the cutter discs 3 that are not needed can be stacked at both ends of the shear roller 2. When it is necessary to increase or decrease the cutter disc 3, first move the frame 10 so that it slides relative to the fixed frame 11, allowing the shear roller 2 to separate from the receiving groove 101. Then, pull the rod 4 so that it slides within the through-groove 23, driving the lifting plate 5 downward through the adjustment mechanism 7, and using the limit groove 812 closest to the through-groove 23 to restrict the rod 4. At this time, the limit member 6 descends with the lifting plate 5, and the limit block 61 moves away from the embedded block 31. The cutter disc 3 can be easily moved on the shear roller 2, facilitating disassembly or installation operations. During the entire pushing and pulling process of the rod 4, the spring 2 92 will be squeezed or pulled to facilitate position adjustment.

[0027] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
