[0002] The ultra-thin strip longitudinal shearing machine is a special equipment for longitudinal shearing of ultra-thin strip steel. The working principle of the ultra-thin strip longitudinal shearing machine is mainly to move the ultra-thin strip steel at a certain speed through the traction of mechanical rollers, and then the cutting tool performs longitudinal shearing on the moving strip steel.

[0003] As in the prior art, the patent with authorization announcement number CN220575203U discloses a steel strip winding device for a longitudinal shearing machine, including a base plate, a bracket fixedly connected to the top surface of the base plate, an electric push rod fixedly connected to the inner wall of the bracket, a connecting plate fixedly connected to the output end of the electric push rod, and a limiting axis slidably connected to the inner wall of the connecting plate, so that the steel strip is longitudinally sheared by the longitudinal shearing and shaping assembly and is pulled between the first clamping roller and the limiting clamping mechanism, and the electric push rod is started to push the first clamping roller to move toward the second clamping roller through the connecting plate, the limiting axis, the connecting frame and the spring to clamp steel strips of different thicknesses, and the steel strip is pulled under multiple shaping rollers and then fixed on the winding roller, and the servo motor is started to drive the winding roller to rotate inside the support block for winding, so as to achieve the goal of facilitating the clamping of steel strips of different thicknesses when winding, and avoid the problem that the existing winding device is difficult to adjust the distance between the clamping rollers, resulting in a large winding gap and poor winding effect when the steel strip is wound.

DETAILED DESCRIPTION

[0017] 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.

[0018] 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.

[0019] The ultra-thin strip longitudinal shearing machine of the present invention, when shearing the ultra-thin strip, the ultra-thin strip will pass between the two shearing components. At this time, the two main shafts 2 will drive the driving wheel 8 connected thereto to rotate, and then drive the driven wheel 18 and the rotating shaft 6 connected thereto to rotate through the conveyor belt 9, and then drive the blade 7 to rotate, so as to realize 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. Only the mounting assembly on the damaged blade 7 needs to be opened to replace the blade 7. Since the damaged blade 7 can be replaced separately without disassembling the entire shearing assembly or stopping the entire equipment, the downtime can be significantly reduced; the shearing assembly and the cutter disc unit are used to cooperate with each other to realize independent driving of the blade 7. 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, which reduces the maintenance difficulty, reduces the downtime, and significantly improves the maintenance efficiency. At the same time, it also avoids the damage of the blade 7 and the increase of maintenance cost caused by frequent disassembly and reinstallation.

[0020] As a preferred technical solution of the present invention, the installation assembly includes a fixed disk 10, a connecting disk 12, a threaded sleeve 13 and a clamping column 15. Each end of the rotating shaft 6 away from the driven wheel 18 is fixedly connected to the fixed disk 10, and each fixed disk 10 is provided with an installation groove 11 corresponding to the position of the blade 7 on the side away from the driven wheel 18. Each fixed disk 10 is connected to a connecting disk 12 on the side away from the driven wheel 18, and each connecting disk 12 is fixedly connected to a threaded sleeve 13 on the side close to the fixed disk 10. Each fixed disk 10 has a threaded groove 14 corresponding to the position of the threaded sleeve 13 on one side, and each connecting disk 12 has a rotating groove 17 on the side away from the fixed disk 10.

[0021] Specifically, when replacing the blade 7, the staff inserts a tool such as a hexagonal wrench into the rotating groove 17, and then the rotating tool drives the connecting plate 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 connecting plate 12 is separated from the fixed plate 10. At this time, the damaged blade 7 can be removed, and the new blade 7 is placed in the installation groove 11. Then the threaded sleeve 13 is aligned with the threaded groove 14, and the connecting plate 12 is reinstalled. As the connecting plate 12 moves, the blade 7 will be continuously squeezed, thereby achieving the fixation of the blade 7.

[0022] As a preferred technical solution of the present invention, a plurality of equally spaced snap-in posts 15 are fixedly connected in each installation slot 11 , and a plurality of snap-in slots 16 corresponding to the positions of the snap-in posts 15 are formed on the surface of each blade 7 .

[0023] Specifically, the clamping column 15 and the clamping groove 16 can be used to limit the blade 7 to avoid asynchronism between the blade 7 and the fixed disk 10 during rotation, thereby avoiding uneven shearing caused by inconsistent rotation speed of the blade 7, helping to improve the shearing accuracy and stability of the longitudinal shearing machine, and can also reduce the wear on the blade 7 and increase the service life of the blade 7.

[0024] As a preferred technical solution of the present invention, each main shaft 2 outer wall is fixedly connected to a fixing rod 19, each driving wheel 8 is fixedly connected to a positioning plate 20 on one side, each positioning plate 20 surface is threadedly connected to a positioning bolt 21, the positioning bolt 21 is against the outer wall of the fixing rod 19, the driving wheel 8 is slidingly connected to the fixing rod 19, each connecting rod 4 outer wall is fixedly connected to a sliding rod 22, the connecting plate 5 is slidingly connected to the sliding rod 22, the end of the connecting plate 5 away from the blade 7 is threadedly connected to a connecting bolt 23, and the connecting bolt 23 is against the outer wall of the sliding rod 22.

[0025] Specifically, the fixed rod 19 can ensure that the main shaft 2 stably drives the driving wheel 8 to rotate, while allowing 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 synchronously slide on the connecting rod 4 along the sliding rod 22. 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, so as to carry out subsequent shearing operations; the fixed rod 19 and the sliding rod 22 are used to allow the blade 7 to adjust its position according to the needs of the shearing width, thereby reducing the dependence on equipment of specific specifications, improving the versatility and flexibility of the equipment, and increasing the utilization rate of the equipment.

[0026] As a preferred technical solution of the present invention, each fixed plate 3 is provided with two sliding grooves 24 corresponding to the position of the connecting rod 4 on one side, and each sliding groove 24 is provided with a limiting groove 25 on the side away from the blade 7. Both ends of each connecting rod 4 are fixedly connected with limiting columns 26, and each limiting column 26 is slidably connected to the limiting groove 25 at the corresponding position. The outer wall of each limiting column 26 is threadedly connected to a limiting sleeve 27, and the limiting sleeve 27 is fitted with the outer wall of the fixed plate 3. Each limiting sleeve 27 is provided with a disassembly groove 28 on the side away from the fixed plate 3.

[0027] 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 be rotated and moved up and down, thereby further improving the freedom of movement of the blade 7, and facilitating the staff to flexibly adjust the position and angle of the blade 7 according to the shape, size and specific requirements of the raw material for shearing, thereby reducing errors and waste in the shearing process, improving shearing accuracy and product quality, and ensuring the best shearing effect and the highest production efficiency; after adjusting the height and rotation angle of the connecting rod 4, the staff uses the limit sleeve 27 and the limit column 26 to limit the connecting rod 4 through the friction force generated by the limit sleeve 27 squeezing the fixed plate 3, thereby ensuring the stability and accuracy of the connecting rod 4 and the blade 7 during the shearing process, the limit column 26 and the limit groove 25 can limit the two ends of the connecting rod 4, ensuring that the connecting rod 4 remains straight and does not tilt, and the disassembly and assembly groove 28 is consistent in shape with the rotation groove 17, and can be inserted by a hexagonal wrench or other similar tools, thereby realizing the disassembly and installation of the limit sleeve 27 and the connecting plate 12.

[0028] As a preferred technical solution of the present invention, a movable groove 30 is opened in the middle of each connecting plate 5, and a movable rod 31 is slidably connected in each movable groove 30. The end of each movable rod 31 close to the main shaft 2 is fixedly connected to a connecting column 32, and the outer wall of each connecting column 32 is rotatably connected to a tension wheel 33.

[0030] Specifically, after adjusting the position of the blade 7, the staff pushes the moving rod 31 forward and backward and uses the tension wheel 33 to prop up the conveyor belt 9, so that the conveyor belt 9 remains taut, ensuring that the blade 7 obtains stable power input during the shearing process, thereby reducing the shearing error caused by unstable power, helping to extend the service life of the blade 7 and reduce 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 prop up 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 operation. At the same time, the design of the limit bolt 35 effectively prevents the moving rod 31 from accidentally moving under the influence of external factors such as various vibrations and impact forces, thereby ensuring the stability and accuracy of the tension of the conveyor belt 9.

[0031] 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 fixing plate 3 .

[0032] Specifically, the anti-slip strip 29 is used to increase the friction between the limit sleeve 27 and the fixed plate 3 to prevent the limit sleeve 27 from sliding or shifting due to vibration, impact or other external factors during the operation of the equipment, ensuring that the limit sleeve 27 can remain stable when bearing a large load, thereby improving the overall stability and reliability of the equipment.
