DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] See also Figures 1 to 7 As shown, a steel coil flying shear includes a bracket 1, two feeding rollers 222 are rotatably installed in the inner cavity of the bracket 1, and a second mounting plate 3 is fixedly installed on the top of the bracket 1; it also includes a pushing mechanism for pushing the sheared steel coil away from the flying shear; the pushing mechanism includes two support plates 34, the two support plates 34 are fixedly installed on the top of the second mounting plate 3, and the two support plates 34 have cutters 342 slidingly installed on the opposite surfaces. Two racks 343 are fixedly installed at the bottom of the cutter 342, and the racks 343 are meshed with incomplete teeth. Wheel 36, the two support plates 34 are rotatably mounted on opposite surfaces with discharge rollers 364, the discharge rollers 364 and one side of the incomplete gear 36 are fixedly connected to a fourth pulley 362, the two fourth pulleys 362 are driven by a third belt 363, one side of the fourth pulleys 362 is fixedly connected to a fourth motor 37, the fourth motor 37 is fixedly mounted on one side of the support plate 34, the bottom of the cutter 342 is fixedly connected to two second spring rods 35, the second spring rods 35 are fixedly mounted on the outer surface of the second mounting plate 3;

[0034] The support plate 34 is provided with a seventh groove 341 on one side, the cutter 342 is slidingly installed on the inner surface of the seventh groove 341, the two incomplete gears 36 are fixedly connected with a transmission shaft 361 on opposite surfaces, the rack 343 is slidingly installed on one side of the support plate 34, the rack 343 is provided with an eighth groove 3431 on one side, the T-shaped block 3432 is slidingly installed on the inner surface of the eighth groove 3431, and the T-shaped block 3432 is fixedly installed on one side of the support plate 34.

[0035] The existing flying shear machine makes the steel coil fall down by gravity after cutting, lacks a structure for pushing out the steel coil, and the steel coil is prone to be stacked in the discharge port when falling down by gravity, thereby affecting subsequent discharge.

[0036] In use, the steel coil is first placed on the outer surfaces of the two feeding rollers 222, and then the steel coil passes through the bottom of the cutter 342. At this time, the fourth motor 37 drives the fourth belt pulley 362 to rotate through the fourth output shaft, and the third belt 363 is driven to rotate. The other fourth belt pulley 362 drives the incomplete gear 36 to rotate, and the transmission shaft 361 drives the two incomplete gears 36 to rotate. When the incomplete gear 36 rotates, it meshes with the rack 343 to drive the rack 343 to move downward. At this time, the T-shaped block 3432 slides on the inner surface of the eighth groove 3431 to limit the rack 343, and the rack 343 drives the cutter 342 to move downward to cut the steel coil. At this time, the cutter 342 presses the second spring rod 35 downward, and after cutting is completed, the incomplete gear 36 is no longer meshed with the rack 343. At this time, the second spring rod 35 is elongated to drive the cutter 342 to move upward. When the steel coil is cut, the other end of the steel coil is fixed, so the discharge roller 364 cannot pull the steel coil at this time. After the steel coil is cut, the fourth belt pulley 362 drives the discharge roller 364 to rotate to move the cut steel coil away from the second mounting plate 3.

[0037] Further, as shown in Figure 3 The top plate 2 is fixedly installed on the top of the support 1, the third groove 201 is formed in the bottom of the top plate 2, the first sliding block 202 is slidingly installed on the inner surface of the third groove 201, and the first mounting plate 21 is fixedly connected to the bottom of the first sliding block 202.

[0038] The two sliding rods 24 are fixedly installed on the inner surface of the top plate 2, the threaded rod 241 is rotatably installed on the inner surface of the top plate 2, the sliding rods 24 are slidingly connected with the first mounting plate 21, the threaded rod 241 is threadedly connected with the first mounting plate 21, one end of the threaded rod 241 is fixedly connected with the first motor 242, and the first motor 242 is fixedly installed on one side of the support 1.

[0039] When the present invention is in use, when conveying the steel coil, the steel coil is first placed between the first mounting plate 21 and the inner wall of the bracket 1, and then the threaded rod 241 is rotated by the output shaft of the first motor 242. Under the limitation of the two slide bars 24, the first mounting plate 21 carries the loading roller 222 from the center of the steel coil through the two loading rollers 222 and is inserted into the inner surfaces of the two second grooves 12, and then the two loading rollers 222 support the steel coil. Since the steel coil has a large mass, in order to prevent the steel coil from bending the threaded rod 241 and the slide bar 24 during use, the first mounting plate 21 is pulled by the first slider 202 to further increase the supporting force of the first mounting plate 21.

[0040] Further, such as Figure 2 and Figure 6 As shown, the inner surface of the bracket 1 is provided with a first groove 11 and two second grooves 12, two first pulleys 22 are rotatably mounted on one side of the first mounting plate 21, the two first pulleys 22 are driven by a first belt 221, the loading roller 222 is fixedly mounted on one side of the first belt 221, and one end of the loading roller 222 is slidably mounted on the inner surface of the second groove 12, one side of one of the first pulleys 22 is fixedly connected to a transmission rod 23, and a limit rod 231 is fixedly mounted on the outer surface of the transmission rod 23;

[0041] A support frame 33 is fixedly mounted on the top of the second mounting plate 3, a feed roller 331 is rotatably mounted in the inner cavity of the support frame 33, a third motor 332 is fixedly connected to one side of the support frame 33, and an output shaft of the third motor 332 is fixedly mounted on one side of the feed roller 331;

[0042] A connecting shaft 333 is fixedly installed on one side of the feed roller 331, and a second pulley 334 is rotatably installed on one side of the bracket 1. A limiting groove 3341 is provided on one side of the second pulley 334. The transmission rod 23 and the limiting rod 231 are slidably installed on the inner surface of the limiting groove 3341. One end of the connecting shaft 333 is fixedly connected to a third pulley 336. The third pulley 336 and the second pulley 334 are driven by a second belt 335.

[0043] When the present invention is in use, the steel coil is at the bottom of the feed roller 331, and the output shaft of the third motor 332 drives the feed roller 331 to rotate to transport the steel coil. The feed roller 331 drives the connecting shaft 333 to rotate, and the connecting shaft 333 further drives the third pulley 336 to rotate. The second belt 335 drives the second pulley 334 to also start to rotate. The second pulley 334 will drive the transmission rod 23 and the limit rod 231 to rotate together. The transmission rod 23 further drives the first pulley 22 to rotate, and the first belt 221 drives the two first pulleys 22 to rotate respectively with the two loading rollers 222, thereby realizing the rotation of the steel coil to transport the steel coil.

[0044] When the first mounting plate 21 slides along the top plate 2, the transmission rod 23 and the limiting rod 231 slide on the inner surface of the limiting groove 3341. The limiting rod 231 limits the transmission rod 23, which can prevent the second pulley 334 from slipping when rotating with the transmission rod 23.

[0045] Further, such as Figure 4 As shown, a mounting frame 4 is fixedly installed on the top of the bracket 1, and two first spring rods 41 are fixedly installed in the inner cavity of the mounting frame 4. The output end of the first spring rod 41 is fixedly connected to a second slider 42, and the second slider 42 is slidably installed in the inner cavity of the mounting frame 4. The opposite surfaces of the two second sliders 42 rotate together and are connected to a limiting roller 43.

[0046] When the present invention is in use, in order to prevent the part of the steel coil that is separated from the whole steel coil from tilting too high, the steel coil is passed through the bottom of the limiting roller 43. At this time, due to the pulling of the steel coil by the flying shear, the steel coil will lift the limiting roller 43, and the limiting roller 43 slides with the second slider 42 on the inner surface of the first spring rod 41. At this time, the two first spring rods 41 jointly support the second slider 42 to prevent the limiting roller 43 from moving too much and losing its restraining effect on the steel coil.

[0047] Further, such as Figure 4 As shown, a fourth groove 31 and a fifth groove 32 are provided on the top of the second mounting plate 3, and two clamping plates 311 are slidably installed on the inner surface of the fourth groove 31.

[0048] When the present invention is in use, in order to prevent the steel coil from tilting during transportation, the output shaft of the second motor 313 drives the bidirectional threaded rod 312 to rotate. The bidirectional threaded rod 312 can drive the two clamps 311 to slide toward each other under the limitation of the fourth groove 31, so that the steel coil is located between the two clamps 311, thereby limiting the position of the steel coil.

[0049] Further, such as Figure 4 and Figure 5 As shown, two sixth grooves 322 are provided on the inner surface of the fifth groove 32, and a third slider 323 is slidably installed on the inner surface of the sixth groove 322. The bottom of the third slider 323 is fixedly connected to an electric telescopic rod 324, and the opposing surfaces of the two third sliders 323 are connected to a matching roller 321 for common rotation.

[0050] The application in use, through the extension of the output end of the electric telescopic rod 324 can bring the third sliding block 323 to slide in the inner surface of the sixth groove 322, the sixth groove 322 further brings the matching roller 321 to slide in the inner surface of the fifth groove 32, thereby achieving the purpose of changing the distance between the matching roller 321 and the material conveying roller 331, which can make the steel coil between the material conveying roller 331 and the matching roller 321 and can be driven by the material conveying roller 331.

[0051] Working principle: the application in use, first make the steel coil between the inner wall of the support 1 and the first mounting plate 21, then through the output shaft of the first motor 242 with the threaded rod 241 rotates, under the limit of two slide rods 24, the first mounting plate 21 with the feeding roller 222 slides at the bottom of the top plate 2 until the feeding roller 222 is inserted into the second groove 12 inner cavity, then make two feeding rollers 222 support the steel coil, through the first sliding block 202 to pull the first mounting plate 21 can reduce the pressure of the slide rod 24 and the threaded rod 241, avoid the steel coil bending the slide rod 24 and the threaded rod 241, then the end of the steel coil from the bottom of the limiting roller 43, through the limiting roller 43 to suppress the steel coil to avoid the height of the steel coil when rotating too high, through the output shaft of the second motor 313 with the bidirectional threaded rod 312 rotates under the limit of the fourth groove 31 makes two clamping plates 311 close to each other to limit the steel coil, avoid the steel coil in the process of conveying skew.
