Description

Technical Field

[0001] This invention belongs to the field of slitting machine technology, specifically relating to a metal coil slitting machine. Background Technology

[0002] Metal coil slitting machine is a device specifically designed for slitting metal coils. It can accurately divide coiled metal sheets into multiple narrow strips of different widths along the longitudinal direction. It is suitable for various metal materials such as carbon steel, stainless steel, copper, and aluminum, and the slitting width can be flexibly adjusted according to production needs.

[0003] However, at present, every time the slitting machine adjusts the cutting width, the cutter head and spacers must be completely removed from the shearing rollers, and then the cutter head and spacers of the corresponding specifications must be recalculated and installed according to the required width. The whole process is cumbersome, time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide a metal coil slitting machine with a quick disassembly and adjustment of the cutter head position in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A metal coil slitting machine includes a base and a fixed frame mounted on the base. Two shearing rollers are rotatably mounted on the fixed frame, and a gear set is provided between the shearing rollers. A motor frame is slidably mounted on the base and is movably connected to the shearing rollers. Multiple cutter discs are sleeved on the shearing rollers, and embedded blocks are provided on the cutter discs.

[0007] It also includes:

[0008] A lifting plate, which is slidably disposed inside the shearing roller;

[0009] A limiting member is slidably disposed on the lifting plate, and the embedding block is embedded between adjacent limiting members;

[0010] A pull rod is slidably disposed in the shearing roller. An adjustment mechanism is connected between the pull rod and the lifting plate, and the pull rod drives the lifting plate to rise and fall through the adjustment mechanism.

[0011] As a further optimization of the present invention, the shearing roller has an installation cavity, and the shearing roller has an embedding groove and a through groove communicating with the installation cavity. The pull rod is slidably disposed in the through groove, and the embedding block is slidably disposed in the embedding groove.

[0012] As a further optimization of the present invention, the limiting member includes a limiting block, a trapezoidal block is fixedly provided at the upper end of the limiting block, and a sliding ear is provided at the lower end of the limiting block.

[0013] As a further optimization of the present invention, the lifting plate is provided with side plates on both sides, and two sliding grooves are provided on the side plates. Guide rods are provided on both sides of the mounting cavity. The guide rods pass through the side plates through the sliding grooves. Multiple uprights are provided on the lifting plate. The sliding ear is slidably mounted on the upright. A spring is sleeved on the upright. The two ends of the spring are respectively connected to the lifting plate and the sliding ear.

[0014] As a further optimization of the present invention, the adjustment mechanism includes multiple rotating rings, each rotating ring being rotatably mounted on a pull rod, a T-shaped rod being fixedly mounted on the rotating ring, mounting plates being fixedly mounted on both sides of the lifting plate, and inclined grooves being formed on the mounting plates, with both ends of the T-shaped rod being slidably mounted in the inclined grooves.

[0015] As a further optimization of the present invention, the pull rod is slidably mounted on the shearing roller through a through groove, a protruding rod is fixedly mounted on the pull rod, a handle is fixedly mounted on one end of the pull rod, and transverse grooves are arrayed on the pull rod.

[0016] As a further optimization of the present invention, a rotating sleeve is rotatably provided on the mounting cavity, and sliding columns are arranged in an array inside the rotating sleeve. The sliding columns are slidably arranged in the transverse groove, and a second spring is provided between the rotating sleeve and the pull rod.

[0017] As a further optimization of the present invention, a limiting sleeve is fixedly provided on one side of the mounting cavity. The limiting sleeve is sleeved on the pull rod, and an E-shaped groove is provided on the limiting sleeve. The protruding rod is embedded in the E-shaped groove.

[0018] As a further optimization of the present invention, the E-shaped groove includes a movable groove, and three limiting grooves that are perpendicularly distributed to the movable groove are connected to the movable groove.

[0019] As a further optimization of the present invention, the motor frame is provided with two receiving grooves, and the shearing roller is embedded in the receiving grooves.

[0020] The beneficial effects of this invention are as follows:

[0021] Unlike existing technologies, this design, through the coordinated operation of the pull rod, adjustment mechanism, and lifting plate, allows for rapid adjustment of the position of the limiting components, enabling flexible switching between three states: initial fixation, complete fixation, and no fixation of the cutter head. This design not only allows for rapid adjustment and stable fixation of the cutter head position, eliminating the need for installing the cutter sleeve, but also simplifies and simplifies the addition, removal, and position adjustment of the cutter head, eliminating the need for complex disassembly and assembly procedures, and greatly improving the ease of operation and work efficiency of the equipment.

[0033] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Example 1: As Figure 1 - Figure 10As shown, a metal coil slitting machine includes a base 1 and a fixed frame 11 mounted on the base 1. Two shearing rollers 2 are rotatably mounted on the fixed frame 11. One of the shearing rollers 2 is connected to a drive motor. A gear set 12 is arranged between the shearing rollers 2. The gear set 12 includes a linkage gear fixed on the shearing roller 2 and two connecting gears rotatably mounted on a connecting rod that mesh with the linkage gear. The two connecting gears mesh with each other for transmission. The connecting rod is connected to a bracket, which is mounted on the base 1. The two shearing rollers 2 rotate in opposite directions through the cooperation of the linkage gear and the connecting gears. A motor frame 10 is slidably mounted on the base 1. The motor frame 10 is threadedly connected to a lead screw 102, which is rotatably mounted in the base 1. The motor frame 10 can be moved on the base 1 by a moving motor driving the lead screw. The motor frame 10 has two receiving grooves 101. The shearing roller 2 is embedded in the receiving grooves 101. Multiple cutter discs 3 are sleeved on the shearing roller 2. Embedded blocks 31 are provided on the cutter discs 3. A lifting plate 5 is slidably mounted, and a limiting component 6 is slidably mounted on the lifting plate 5. An embedded block 31 can be embedded between adjacent limiting components 6. A pull rod 4 is slidably mounted through the shearing roller 2, and an adjustment mechanism 7 is connected between the pull rod 4 and the lifting plate 5. The pull rod 4 drives the lifting plate 5 to rise and fall through the adjustment mechanism 7. During operation, the two shearing rollers 2 mounted on the fixed frame 11 on the base 1 rotate synchronously in opposite directions with the help of a gear set 12. The ends of the shearing rollers 2 are embedded in the receiving grooves 101 opened on the motor frame 10 to support the shearing rollers 2. Multiple cutter discs 3 arranged at preset width intervals on the shearing rollers 2 form shearing blades. When the rolled material passes through, the rotating cutter discs 3 apply shearing force to cut it longitudinally into multiple narrow strips in one go. By operating the pull rod 4, the lifting plate 5 can be raised and lowered with the help of the adjustment mechanism 7, thereby limiting or releasing the cutter discs 3. There is no need to completely disassemble the cutter discs 3 and the spacers, which fundamentally simplifies the process of adjusting the cutting width. This not only saves a lot of time but also reduces labor costs, making the operation of the equipment more efficient and convenient.

[0035] like Figure 6 and Figure 9As shown, the adjusting mechanism 7 includes multiple rotating rings 71, which are rotatably mounted on the pull rod 4. A T-shaped rod 73 is fixedly mounted on each rotating ring 71. Mounting plates 72 are fixedly mounted on both sides of the lifting plate 5, and inclined grooves 721 are formed on the mounting plates 72. The two ends of the T-shaped rod 73 are slidably positioned within the inclined grooves 721. When the pull rod 4 moves linearly, the rotating rings 71 move synchronously. At this time, the T-shaped rod 73 slides within the inclined grooves 721. This sliding method smoothly and accurately converts the linear movement of the pull rod 4 into the lifting movement of the lifting plate 5. This conversion method is not only highly accurate but also stable, ensuring the smoothness of the lifting plate 5 during its ascent or descent. This ensures that the limiting component 6 can accurately limit or release the embedded block 31 of the cutter head 3, providing reliable power transmission for the position adjustment of the cutter head 3.

[0036] like Figure 3 , Figure 5 and Figure 7 As shown, the shearing roller 2 has an installation cavity 22, and the shearing roller 2 has an embedding groove 21 and a through groove 23 communicating with the installation cavity 22. The embedding block 31 is slidably disposed 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 head 3. The pull rod 4 is slidably disposed in the through groove 23. The installation cavity 22 provides a closed and stable installation space for internal components such as the lifting plate 5 and the limiting member 6, ensuring that these components are not affected by external factors during operation and can operate normally. When the cutter head 3 moves, the embedding groove 21 plays a strict guiding role for the sliding of the embedding block 31, ensuring that the cutter head 3 can only move along the set direction and will not deviate, thereby ensuring the stability of the cutter head 3 during movement. At the same time, it allows the cutter head 3 to rotate synchronously with the shearing roller 2 during operation. The through groove 23 provides a guiding path for the sliding of the pull rod 4, so that the operating force of the pull rod 4 can be effectively transmitted to internal components such as the adjustment mechanism 7.

[0037] like Figure 8 As shown, the limiting member 6 includes limiting blocks 61. Adjacent limiting blocks 61 can clamp the embedded block 31. A trapezoidal block 62 is fixedly provided at the upper end of the limiting block 61, and a sliding ear 63 is provided at 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 head 3. By clamping the embedded block 31 with adjacent limiting blocks 61, the position of the cutter head 3 is fixed, ensuring that the cutter head 3 will not be displaced during the cutting process, thus ensuring the stability of the cutting operation. The inclined surface design of the trapezoidal block 62 allows the embedded block 31 to press against the inclined surface of the trapezoidal block 62 in the moving direction, which can easily allow the limiting block 61 to slide on the lifting plate 5, allowing the cutter head 3 to move along the embedded groove 21 under the action of external force. The sliding ear 63 provides stable support for the up and down sliding of the limiting member 6.

[0038] like Figure 7 - Figure 8 As shown, the lifting plate 5 has side plates 51 on both sides, with two sliding grooves 511 on each side plate 51. Guide rods 512 are provided on both sides of the mounting cavity 22, passing through the sliding grooves 511 and extending through the side plates 51. Multiple uprights 52 are provided on the lifting plate 5. Sliding ears 63 are slidably mounted on the uprights 52. Springs 53 are sleeved on the uprights 52, with both ends of the springs 53 connected to the lifting plate 5 and the sliding ears 63, respectively. During the lifting process of the lifting plate 5, the cooperation between the guide rods 512 and the sliding grooves 511 provides guidance and limitation, restricting 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 limiting component 6 failing to accurately limit movement due to the offset of the lifting plate 5. The uprights 52 provide a path for the sliding ears 63 to slide, ensuring that the limiting component 6 can only slide up and down. When the embedded block 31 separates from the trapezoidal block 62, the spring 53 will reset under its own elastic force, causing the limiting member 6 to move upward and reset, thus providing initial limiting for the embedded block 31 in a timely manner, improving the stability of the cutter head 3 after adjustment, and laying the foundation for subsequent fixing work.

[0039] like Figure 9 As shown, the pull rod 4 is slidably mounted on the shearing roller 2 through the through groove 23. A rotating sleeve 9 is rotatably mounted on the mounting cavity 22 and is fitted onto the pull rod 4. A spring 92 is provided between the rotating sleeve 9 and the pull rod 4. A protruding rod 41 is fixedly mounted on the pull rod 4. A handle 43 is fixedly mounted on one end of the pull rod 4. A transverse groove 42 is arrayed on the pull rod 4. A sliding column 91 is arrayed inside the rotating sleeve 9 and is slidably mounted in the transverse groove 42. 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 between the transverse groove 42 and the sliding column 91 allows the rotating sleeve 9 to rotate synchronously with the pull rod 4 without affecting the axial sliding of the pull rod 4.

[0040] like Figure 10As shown, a limiting sleeve 8 is fixedly installed on the mounting cavity 22. The limiting sleeve 8 is fitted onto the pull rod 4. The limiting sleeve 8 has an E-shaped groove 81, which consists of a movable groove 811 and three limiting grooves 812 perpendicularly connected to it. When the protruding rod 41 is embedded in different limiting grooves 812, the lifting plate 5 corresponds to different heights. When it is necessary to adjust the axial position of the pull rod 4, the movable groove 811 allows the protruding rod 41 to move freely 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, rotating the pull rod 4 will embed the protruding rod 41 into the corresponding limiting groove 812, thus 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 positioned in different positions such as the middle, rising, or falling. At the same time, when the second spring 92 is not charged, the protruding rod 41 is located in the limiting groove 812 in the middle of the moving groove 811, so that the user can quickly rotate the protruding rod 41 into the limiting groove 812. When pushing or pulling the lever 4, the second spring 92 can be charged. When the lever 4 is pushed or pulled to the limit position, the protruding rod 41 can be quickly embedded into the corresponding limiting groove 812. When the shearing roller 2 is working, the protruding rod 41 is stably restricted in the limiting groove 812 under the action of centrifugal force, and will not accidentally fall out. This ensures the reliability and speed of the adjustment and fixing process of the cutter head 3, significantly improves the accuracy of equipment operation, and ensures the smooth progress of the slitting work.

[0041] It should be noted that when adjusting the spacing of the cutter discs 3, the metal coil slitting machine pulls the lever 4 by the handle 43. The rotating ring 71 in the adjusting mechanism 7 moves with the lever 4, and the T-shaped rod 73 slides in the inclined groove 721 of the mounting plate 72. This drives the lifting plate 5 to slide downward along the slide groove 511 in the mounting cavity 22 of the shearing roller 2 via the guide rod 512. Then, the lever 4 is rotated to insert the protrusion 41 into the middle limiting groove 812, and the lifting plate 5 is at the middle height. At this time, the embedded block 31 on the cutter head 3 is at the same height as the trapezoidal block 62 of the limiting member 6. When the cutter head 3 is moved, the embedded block 31 slides in the embedded groove 21. It will press the inclined surface of the trapezoidal block 62 in the direction of movement, so that the limiting block 61 slides down on the upright 52 through the sliding ear 63 and stores force on the spring 53 to realize the movement of the cutter head 3. When the embedded block 31 separates from the trapezoidal block 62, the limiting member 6 moves upward and resets under the reset action of the spring 53. At the same time, the trapezoidal blocks 62 on both sides of the embedded block 31 initially limit it.

[0042] Once all the cutter discs 3 are adjusted to the designated positions, push the pull rod 4 to drive the lifting plate 5 to rise through the adjustment mechanism 7 until the limit block 61 is located on both sides of the embedded block 31, fixing the position of the cutter discs 3. Then, the cutter discs 3 with the spacing adjusted in the middle of the shearing roller 2 can be used for longitudinal shearing, and the cutter discs 3 that are not needed can be stacked at both ends of the shearing roller 2.

[0043] When it is necessary to add or remove the cutter head 3, first move the motor frame 10 so that it slides relative to the fixed frame 11, allowing the shearing roller 2 to separate from the receiving groove 101. Then pull the pull rod 4 so that it slides within the through groove 23, driving the lifting plate 5 to descend via the adjusting mechanism 7, and using the limiting groove 812, which is closest to the through groove 23, to restrict the pull rod 4. At this time, the limiting member 6 descends with the lifting plate 5, and the limiting block 61 moves away from the embedded block 31, allowing the cutter head 3 to move easily on the shearing roller 2, facilitating disassembly or installation. During the entire pushing and pulling process of the pull rod 4, the spring 92 will be squeezed or pulled to coordinate with the position adjustment.

[0044] The embodiments described above are merely examples of several implementations of the present invention, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
