Description

Technical Field

[0001] The present invention relates to the technical field of slitting machines, and particularly to an ultra-thin strip steel slitting machine. Background Art

[0002] An ultra-thin strip steel slitting machine is a special equipment for longitudinally shearing ultra-thin strip steel. The working principle of the ultra-thin strip steel slitting machine is mainly to make the ultra-thin strip steel move at a certain speed through the traction of mechanical rollers, and then longitudinally shear the moving strip steel with cutting tools.

[0003] For example, in the prior art, the patent with the authorization announcement number CN220575203U discloses a slitting machine steel strip coiling device, including a bottom plate. A bracket is fixedly connected to the top surface of the bottom plate. An electric push rod is fixedly connected to the inner wall of the bracket. The output end of the electric push rod is fixedly connected to a connecting plate. A limiting shaft is slidably connected to the inner wall of the connecting plate. After the steel strip is longitudinally sheared by the longitudinal shearing and shaping assembly, it is pulled between the first clamping roller and the limiting clamping mechanism. The electric push rod is started to push the first clamping roller towards the second clamping roller to clamp steel strips of different thicknesses through the connecting plate, the limiting shaft, the connecting frame and the spring. After the steel strip is pulled under multiple shaping rollers, it is fixed on the coiling roller. The servo motor is started to drive the coiling roller to rotate inside the support block for coiling work, achieving the goal of facilitating the clamping of steel strips of different thicknesses during coiling, and avoiding the problem that the existing coiling device has a large coiling gap and poor coiling effect when coiling the steel strip due to the difficulty in adjusting the distance between the clamping rollers.

[0004] However, the above-mentioned slitting machine has certain defects when in use:

[0005] The above-mentioned slitting machine is designed to install the shearing blades on the same shaft roller. This design structurally limits the independent replacement of the blades. When the shearing blade in the middle is damaged, due to structural limitations, all the blades on one side need to be removed first, which not only increases the difficulty of maintenance, but also prolongs the downtime.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] See also Figures 1 to 11 , an ultra-thin strip steel longitudinal shearing machine, comprising a device body 1 and two main shafts 2 connected to the device body 1, two symmetrically arranged fixed plates 3 are fixedly connected to the surface of the device body 1, and two vertically symmetrically placed shearing components are connected between the two fixed plates 3, each shearing component comprises a connecting rod 4 and a cutter disc unit, each connecting rod 4 is connected to the two fixed plates 3 at both ends, and a plurality of cutter disc units are equidistantly connected to the outer wall of each connecting rod 4, and the cutter disc unit comprises a connecting plate 5, a rotating shaft 6, a blade 7, a driving wheel 8, a conveyor belt 9 and a driven wheel 18, a plurality of connecting plates 5 are connected to the outer wall of each connecting rod 4, and the connecting plate 5 is rotatably connected to the rotating shaft 6 at one end away from the connecting rod 4, and a driven wheel 18 is fixedly connected to one side of the rotating shaft 6, and a plurality of driving wheels 8 corresponding to the positions of the driven wheels 18 are connected to the two main shafts 2, and each driven wheel 18 is connected to the nearest driving wheel 8 through a conveyor belt 9, and a blade 7 is connected to the end of each rotating shaft 6 away from the driven wheel 18 through a mounting component.

[0035] In the ultra-thin strip longitudinal shearing machine of the present invention, when shearing the ultra-thin strip, the ultra-thin strip passes through between two shearing components. At this time, two main shafts 2 drive the driving wheels 8 connected thereto to rotate, and then drive the driven wheels 18 and the rotating shafts 6 connected thereto to rotate through the conveyor belt 9, and then drive the blades 7 to rotate, realizing the longitudinal shearing of the ultra-thin strip; when the blade 7 is damaged, there is no need to remove the remaining blades 7 on the side of the damaged blade 7. Just open the installation component on the damaged blade 7, and the blade 7 can be replaced. Since the damaged blade 7 can be replaced separately without disassembling the entire shearing component or stopping the entire device, the downtime can be significantly reduced; by using the mutual cooperation between the shearing component and the cutter head unit, the independent drive of the blade 7 is realized. Compared with the existing method of directly installing the blade 7 on the main shaft 2, the damaged blade 7 can be quickly replaced without disassembling the remaining blades 7, reducing the maintenance difficulty, reducing the downtime, significantly improving the maintenance efficiency, and at the same time avoiding the damage of the blade 7 and the increase of maintenance cost caused by frequent disassembly and reinstallation.

[0036] As a preferred technical solution of the present invention, the installation component includes a fixed disk 10, a connection disk 12, a threaded sleeve 13 and a clamping post 15. One end of each rotating shaft 6 away from the driven wheel 18 is fixedly connected with a fixed disk 10. An installation groove 11 corresponding to the position of the blade 7 is opened on one side of each fixed disk 10 away from the driven wheel 18. A connection disk 12 is connected to one side of each fixed disk 10 away from the driven wheel 18. A threaded sleeve 13 is fixedly connected to one side of each connection disk 12 close to the fixed disk 10. A threaded groove 14 corresponding to the position of the threaded sleeve 13 is opened on one side of each fixed disk 10. A rotating groove 17 is opened on one side of each connection disk 12 away from the fixed disk 10.

[0037] Specifically, when replacing the blade 7, the staff inserts tools such as a hex wrench into the rotating groove 17, and then rotates the tool to drive the connection disk 12 to rotate, so that the threaded sleeve 13 moves in the threaded groove 14. When the threaded sleeve 13 is separated from the threaded groove 14, the connection disk 12 is separated from the fixed disk 10. At this time, the damaged blade 7 can be removed, the new blade 7 is placed in the installation groove 11, and then the threaded sleeve 13 is aligned with the threaded groove 14, and the connection disk 12 is reinstalled. As the connection disk 12 moves, the blade 7 will be continuously squeezed, so as to realize the fixation of the blade 7.

[0038] As a preferred technical solution of the present invention, a plurality of equally spaced clamping posts 15 are fixedly connected in each installation groove 11, and a plurality of clamping grooves 16 corresponding to the positions of the clamping posts 15 are opened on the surface of each blade 7.

[0039] Specifically, the clamping post 15 and the clamping groove 16 can be used to limit the blade 7, preventing out-of-sync movement between the blade 7 and the fixed disk 10 during the rotation of the blade 7, thus avoiding uneven shearing caused by inconsistent rotational speeds of the blade 7. This helps improve the shearing accuracy and stability of the slitting machine, reduces wear on the blade 7, and increases the service life of the blade 7.

[0040] As a preferred technical solution of the present invention, a fixed rod 19 is fixedly connected to the outer wall of each main shaft 2. A positioning plate 20 is fixedly connected to one side of each driving wheel 8. A positioning bolt 21 is threadedly connected to the surface of each positioning plate 20. The positioning bolt 21 abuts against the outer wall of the fixed rod 19. The driving wheel 8 is slidably connected to the fixed rod 19. A sliding rod 22 is fixedly connected to the outer wall of each connecting rod 4. The connecting plate 5 is slidably connected to the sliding rod 22. A connecting bolt 23 is threadedly connected to the end of the connecting plate 5 away from the blade 7. The connecting bolt 23 abuts against the outer wall of the sliding rod 22.

[0041] Specifically, while ensuring the stable rotation of the driving wheel 8 by the main shaft 2, the fixed rod 19 enables the driving wheel 8 to slide along the fixed rod 19, thereby adjusting the position of the driving wheel 8 to adapt to shearing operations of different widths. When adjusting the position of the driving wheel 8, the connecting plate 5 will slide synchronously along the sliding rod 22 on the connecting rod 4. After the adjustment is completed, the driving wheel 8 and the connecting plate 5 can be fixed respectively by the positioning bolt 21 and the connecting bolt 23, and then subsequent shearing operations can be carried out; by using the fixed rod 19 and the sliding rod 22, the blade 7 is allowed to adjust its position according to the needs of the shearing width, reducing the dependence on equipment of specific specifications, improving the versatility and flexibility of the equipment, and increasing the utilization rate of the equipment.

[0042] As a preferred technical solution of the present invention, two sliding grooves 24 corresponding to the positions of the connecting rods 4 are provided on one side of each fixing plate 3. A limiting groove 25 is provided on the side of each sliding groove 24 away from the blade 7. A limiting post 26 is fixedly connected to both ends of each connecting rod 4. Each limiting post 26 is slidably connected to the limiting groove 25 at the corresponding position. A limiting sleeve 27 is threadedly connected to the outer wall of each limiting post 26. The limiting sleeve 27 is in contact with the outer wall of the fixing plate 3. A disassembly and assembly groove 28 is provided on the side of each limiting sleeve 27 away from the fixing plate 3.

[0043] Specifically, by utilizing the mutual cooperation between the sliding groove 24 and the connecting rod 4, the connecting rod 4 and the connecting plate 5 thereon can achieve rotational and vertical movement operations, thereby further improving the movement freedom of the blade 7, facilitating the staff to flexibly adjust the position and angle of the blade 7 according to the shape, size of the raw material and the specific requirements of shearing, thus reducing the errors and waste in the shearing process, improving the shearing precision and product quality, and ensuring the best shearing effect and the highest production efficiency; after adjusting the height and rotational angle of the connecting rod 4, the staff uses the limiting sleeve 27 and the limiting post 26, and through the frictional force generated by the limiting sleeve 27 pressing the fixed plate 3, the limiting of the connecting rod 4 is realized, thereby ensuring the stability and precision of the connecting rod 4 and the blade 7 during the shearing process. The limiting post 26 and the limiting groove 25 can limit both ends of the connecting rod 4 to ensure that the connecting rod 4 remains straight and does not skew. The disassembly and installation groove 28 and the rotating groove 17 have the same shape, and can be inserted by tools such as hex wrenches, so as to realize the disassembly and installation of the limiting sleeve 27 and the connecting disk 12.

[0044] As a preferred technical solution of the present invention, a moving groove 30 is provided in the middle of each connecting plate 5, a moving rod 31 is slidably connected in each moving groove 30, a connecting column 32 is fixedly connected to one end of each moving rod 31 close to the main shaft 2, a tension wheel 33 is rotatably connected to the outer wall of each connecting column 32, and each tension wheel 33 is in transmission connection with the conveyor belt 9 installed on the corresponding connecting plate 5.

[0045] As a preferred technical solution of the present invention, a fixed column 34 is fixedly connected to one side of each connecting plate 5, a limit bolt 35 is threadedly connected in each fixed column 34, and each limit bolt 35 abuts against the outer wall of the moving rod 31.

[0046] Specifically, after adjusting the position of the blade 7, the staff pushes the moving rod 31 back and forth, uses the tension wheel 33 to lift the conveyor belt 9, so that the conveyor belt 9 remains in a taut state, ensuring a stable power input for the blade 7 during the shearing process, thereby reducing the shearing error caused by unstable power, helping to extend the service life of the blade 7, reducing the replacement frequency and downtime; the limit bolt 35 can lock the position of the moving rod 31. When the moving rod 31 is adjusted to an appropriate position to lift the tension wheel 33 and keep the conveyor belt 9 taut, the limit bolt 35 can ensure that this position does not change during the operation of the equipment, ensuring that the conveyor belt 9 remains taut during the operation. At the same time, the design of the limit bolt 35 effectively prevents the moving rod 31 from accidentally moving under the action of external factors such as various vibrations and impact forces, thereby ensuring the stability and precision of the tension of the conveyor belt 9.

[0047] As a preferred technical solution of the present invention, a plurality of anti-slip strips 29 are fixedly connected to one side of each limiting sleeve 27 close to the fixed plate 3.

[0048] Specifically, the anti-slip strip 29 is used to increase the friction between the limit sleeve 27 and the fixed plate 3, prevent the limit sleeve 27 from sliding or shifting due to vibration, impact force or other external factors during the operation of the device, ensure that the limit sleeve 27 can still maintain stability when bearing a large load, thereby improving the overall stability and reliability of the device.
