[0028] Traditionally, the removal of steel coil strapping has relied primarily on manual labor. Workers manually cut the strapping using tools such as scissors and pliers, then manually remove the cut strapping from the steel coil. This method is not only labor-intensive and inefficient, but also poses significant safety risks, such as worker injury due to improper operation. Furthermore, manual operation makes it difficult to ensure consistency and accuracy in each unbundling operation, potentially damaging the surface of the steel coil and affecting product quality.
[0029] In the field of steel coil strip unbundling, although there have been some attempts at automated unbundling equipment, the existing equipment often cannot effectively fix the cut end after cutting the strip, so that the subsequent strip removal work still needs to rely on manual completion, and cannot realize the truly automated unbundling process.
[0030] As Figs. 1 to 4 shown, to solve the above technical problems, the embodiment of the present application provides an automatic steel coil strip unbundling device, which comprises a mounting shell 1 connected to a mechanical arm, and a shearing assembly 2 connected to the mounting shell 1; the shearing assembly 2 comprises a first linear driving device 21, a second linear driving device 22, a sliding block 23, a first shearing arm 24 and a second shearing arm 25; the sliding block 23 is slidingly connected to the mounting shell 1 through a guide rail 26, the movable end of the first linear driving device 21 is connected to the sliding block 23, and is used to drive the sliding block 23 to displace along the guide rail 26; the first shearing arm 24 and the second shearing arm 25 are both hinged to the sliding block 23, the first shearing arm 24 is connected with the sliding block 23 through a first return spring 27, and the second shearing arm 25 is connected with the sliding block 23 through a second return spring 28; the movable end of the second linear driving device 22 pushes the second shearing arm 25, so as to drive the second shearing arm 25 to complete a shearing action in cooperation with the first shearing arm 24; the other side of the mounting shell 1 opposite to the shearing assembly 2 is connected with a pressing assembly 3, the pressing assembly 3 comprises a third linear driving device 31, a mounting seat 32, a pressing rod 33 and a connecting rod 34; the mounting seat 32 is fixed to the mounting shell 1, the movable end of the third linear driving device 31 is rotationally connected with one end of the pressing rod 33, the middle fulcrum of the pressing rod 33 is rotationally connected with the mounting seat 32 through the connecting rod 34, and the other end of the pressing rod 33 is clamped in cooperation with the first shearing arm 24.
[0031] The mechanical arm accurately moves the entire unbundling device to the position of the steel coil strip, so that the device is accurately docked with the steel coil strip to be unbundled, and prepares for subsequent unbundling operation.
[0032] In the shearing assembly 2, the sliding block 23 is slidingly connected with the mounting shell 1 through the guide rail 26, and the movable end of the first linear driving device 21 is connected with the sliding block 23. When the first linear driving device 21 is started, the movable end thereof pushes the sliding block 23, so that the sliding block 23 displaces along the guide rail 26. The first return spring 27 and the second return spring 28 keep the first shearing arm 24 and the second shearing arm 25 in the open position in the initial state, so as to provide a reset function for subsequent shearing action.
[0033] After the mechanical arm positions the device to the steel coil banded steel, the first shearing arm 24 is attached to the surface of the steel coil. The first linear drive device 21 is actuated to push the sliding block 23 to move, and the sliding block 23 drives the first shearing arm 24 to shovel the banded steel. At the same time, the end of the second shearing arm 25 is located at the movable end of the second linear drive device 22. Then, the second linear drive device 22 is actuated, and the movable end of the second linear drive device 22 presses the second shearing arm 25 downward, so that the second shearing arm 25 rotates around the hinge point with the sliding block 23, and cooperates with the first shearing arm 24 to complete the shearing action and cut the banded steel.
[0034] In the pressing assembly 3, the mounting seat 32 is fixed on the mounting shell 1, the movable end of the third linear drive device 31 is rotationally connected with one end of the pressing rod 33, the middle support point of the pressing rod 33 is rotationally connected with the mounting seat 32 through the connecting rod 34, forming a lever structure. When the first shearing arm 24 shovels the banded steel, the third linear drive device 31 is actuated, and the movable end of the third linear drive device 31 pushes the pressing rod 33 to rotate around the middle support point. The other end of the pressing rod 33 is rotated accordingly, and cooperates with the first shearing arm 24 to clamp the banded steel.
[0035] The pressing assembly 3 adopts a lever structure, and the third linear drive device 31 actuates the pressing rod 33 to cooperate with the first shearing arm 24 to clamp the banded steel. After the banded steel is cut, one end of the banded steel is still clamped, which facilitates the subsequent dragging of the banded steel to the winding station by the mechanical arm, greatly improves the automation degree and working efficiency of the entire unbundling process, effectively reduces manual operation, and reduces labor intensity and cost.
[0036] In some embodiments, one end of the pressing rod 33 close to the first shearing arm 24 is provided with a circular arc surface 331, and the circular arc surface 331 is provided with a plurality of anti-skid stripes.
[0037] When the unbundling device operates on the banded steel of the steel coil, the circular arc surface 331 can better fit the surface of the banded steel that is shoveled, and press the banded steel to the first shearing arm 24. The plurality of anti-skid stripes on the circular arc surface 331 can be embedded into the surface of the banded steel when the pressing rod 33 cooperates with the first shearing arm 24 to clamp the banded steel, thereby increasing the friction between the pressing rod 33 and the banded steel.
[0038] In some embodiments, the pressing rod 33 is an arc-shaped rod, and the middle part of the pressing rod 33 is provided with a mounting groove 332, and a pin shaft is connected in the mounting groove 332. The connecting rod 34 is rotationally connected with the pin shaft, and the other end of the connecting rod 34 is rotationally connected with the mounting seat 32.
[0039] The shape design of the arc-shaped rod makes the pressing rod 33 more accurately fit the position of the banded steel during rotation, thereby improving the clamping accuracy. The rotation connection between the pin shaft in the mounting groove 332 and the connecting rod 34 is simple and reliable, reduces the wear and failure rate between components, and is convenient for installation and maintenance.
[0040] In some embodiments, the mounting seat 32 is connected with a limiting plate 321, one end of the limiting plate 321 is provided with a limiting groove 322, and one end of the first shearing arm 24 is provided with a beveled shovel part 241 which is inserted and matched with the limiting groove 322.
[0041] In the process of disassembling the bundle, the first linear driving device 21 drives the sliding block 23 to move, thereby driving the first shearing arm 24 to move towards the bundle, and the beveled shovel part 241 naturally shovels the bundle. At the same time, the limiting plate 321 is provided with a limiting groove 322 at one end. With the movement of the first shearing arm 24, the beveled shovel part 241 will gradually be inserted into the limiting groove 322, and through this inserted and matched, the position of the first shearing arm 24 is accurately limited, so as to ensure that the first shearing arm 24 is in the accurate position after shoveling the bundle, and to prepare for the subsequent cooperation with the second shearing arm 25 to complete the shearing action.
[0042] In some embodiments, one end of the second shearing arm 25 is provided with a guide wheel 251, and the movable end of the second linear driving device 22 drives the second shearing arm 25 to move through the guide wheel 251.
[0043] The guide wheel 251 converts the sliding friction between the movable end of the second linear driving device 22 and the second shearing arm 25 into rolling friction, reduces the friction, makes the contact between the movable end of the second linear driving device 22 and the second shearing arm 25 more smooth, reduces the wear between the components, and prolongs the service life of the device.
[0044] In some embodiments, the mounting seat 32 is provided with a shaft hole, and the movable shaft of the third linear driving device 31 is movably arranged through the shaft hole.
[0045] The shaft hole provides accurate guidance for the movable shaft, so that the movable shaft will not deviate or shake during movement, and ensures that the power of the third linear driving device 31 can be stably and accurately transmitted to the pressing rod 33.
[0046] In some embodiments, the first shearing arm 24 is rotationally connected to the sliding block 23, the second shearing arm 25 is rotationally connected to the first shearing arm 24, and the first shearing arm 24 is provided with a limiting block 243 for limiting the abutment of the second shearing arm 25 in the maximum opening state.
[0047] In the initial state, the first shearing arm 24 and the second shearing arm 25 are in the maximum opening position, at this time the second shearing arm 25 abuts on the limiting block 243 provided on the first shearing arm 24, and the limiting block 243 limits the second shearing arm 25 to prevent it from being excessively opened. After shearing is completed, the second shearing arm 25 can be returned to the maximum opening state of abutting with the limiting block 243 under the action of the second return spring 28.
[0048] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
