Summary of the invention

[0005] In order to improve the stability of the support roller, the present application provides an uncoiler.

[0006] The present application provides an unwinding machine, which adopts the following technical solution: Uncoiler, including: A base, one end of which is provided with a frame, and one end of which is provided with a supporting roller for the steel coil to be sleeved; The lateral limiting mechanism is arranged on the frame and located on one side of the supporting roller, and performs axial limiting on the steel coil on the supporting roller; The clamping mechanism is arranged on the frame and clamps the outer side of the steel coil; A feeding mechanism is arranged on the base and is used to temporarily place the steel coils and transport the steel coils thereon to the supporting rollers; The supporting mechanism is arranged on the base and located at the other end of the supporting roller, and supports the other end of the supporting roller.

The supporting mechanism can support the other end of the supporting roller, so that the force on both ends of the supporting roller is more even, so as to improve the stability of the supporting roller when it rotates.

[0011] By adopting the above technical scheme, since a plurality of flaring grooves are provided, the plug-in block can be first inserted into the flaring groove, and under the guidance of the flaring groove, the inner ring of the supporting bearing is driven to rotate a certain angle to correct the angle of the plug-in block so that the plug-in block can be aligned with the plug-in groove. Finally, one end of the support roller can be inserted into the inner ring of the supporting bearing, and the plug-in block can be inserted into the plug-in groove, so that when the support roller rotates, the inner ring of the stripping bearing can be driven to rotate together, thereby supporting one end of the support roller.

[0013] By adopting the above technical scheme, the output end of the swing cylinder can drive the clamping swing shaft to rotate a certain angle, so that the lower end of the clamping swing arm swings. Since the clamping swing arm is arranged in an arc shape, the clamping wheel can contact the outside of the steel coil, thereby being able to clamp the outside of the steel coil to a certain extent, so that the steel coil is not easily unrolled due to its own gravity.

[0014] Optionally, the lateral limiting mechanism includes a lateral seat arranged on one side of the frame, a bidirectional screw rotatably connected to the lateral seat, two internally threaded seats threadedly sleeved on the bidirectional screw, a blocking rod hinged at one end of the internally threaded seat and blocking the end of the steel coil, and a handwheel arranged at one end of the bidirectional screw, the internally threaded seat is slidably connected to the lateral seat, and the two blocking rods respectively block the two ends of the steel coil.

[0015] By adopting the above technical solution, the steel coil is installed on the outside of the material roller, and after the supporting mechanism supports one end of the material roller, the blocking rod is rotated to make the blocking rod droop away from one end of the internal threaded seat, so that the two blocking rods can be respectively located at the two ends of the steel coil, and then the hand wheel is rotated to drive the bidirectional lead screw to rotate, thereby driving the two internal threaded seats to move in opposite directions, so that the two blocking rods are close to each other, so that the two blocking rods can respectively block the two ends of the steel coil, making it difficult for the steel coil to deviate.

Then, the height of the receiving seat is raised by the height adjustment assembly so that the center of the steel coil is aligned with the supporting roller, and then the feeding drive assembly adjusts the position of the moving seat so that the steel coil gradually approaches the supporting roller and is finally mounted on the supporting roller.

[0018] Optionally, the feed drive assembly includes a feed drive member disposed in the movable seat, a feed drive gear disposed at the output end of the feed drive member, and a feed drive rack disposed on the base, and the feed drive gear is meshed with the feed drive rack.

During the extension of the piston rod of the steel roll clamping cylinder, its outer side can contact the bottom of the end limit seat and drive the end limit seat to rise to protrude from the top of the receiving seat.

[0021] By adopting the above technical solution, when the piston rod of the steel coil clamping cylinder is extended, the lower ends of the two steel coil swing shafts will move away from each other, so that the multiple steel coil clamping arms located on both sides of the steel coil are close to each other. Since the lower ends of the two steel coil swing shafts will gradually rise, the steel coil clamping cylinder will be driven to rise a certain distance, and the end limit seat will be driven to rise, so that the two end limit seats can limit the two ends of the steel coil respectively, so as to improve the stability of the steel coil and prevent it from being offset.

DETAILED DESCRIPTION

[0029] The following is combined with Figures 1 to 5 This application is described in further detail.

[0030] The present application embodiment discloses a decoiler. Figure 1 The uncoiler includes a base 1, a lateral limit mechanism 2, a clamping mechanism 3, a feeding mechanism 4 and a supporting mechanism 5. A frame 11 is fixed at one end of the top of the base 1. A support roller 12 is connected to one end of the frame 11 for horizontal rotation. A motor is installed in the frame 11, and the motor drives the support roller 12 to rotate through a reducer. The support roller 12 is provided with a steel coil, and a tensioning mechanism 121 is installed on the outer side of the support roller 12. It should be noted that the tensioning mechanism 121 is a prior art and will not be described in detail here.

[0031] The feeding mechanism 4 is installed on the base 1. The feeding mechanism 4 can be used to temporarily place the steel coil, and the feeding mechanism 4 can transport the steel coil placed thereon to the supporting roller 12. The supporting mechanism 5 is installed on the base 1 and is located at the other end of the supporting roller 12. The supporting mechanism 5 can support the other end of the supporting roller 12. The lateral limiting mechanism 2 is installed on the frame 11 and is located on one side of the supporting roller 12. The lateral limiting mechanism 2 axially limits the steel coil on the supporting roller 12, so that the steel coil on the supporting roller 12 is not easy to move axially. The clamping mechanism 3 is installed on the frame 11. The clamping mechanism 3 is located on the side of the supporting roller 12 away from the lateral limiting mechanism 2. The clamping mechanism 3 can clamp the outer side of the steel coil, so that when the steel coil is unrolled, the steel coil is not easy to loosen due to its own gravity.

[0032] Reference Figure 1 and Figure 2 Preferably, the feeding mechanism 4 includes a moving seat 41, a feeding drive assembly 42, a height adjustment assembly 43, a receiving seat 44 and a steel coil clamping assembly 45. The moving seat 41 is slidably connected to the top of the base 1, and the moving seat 41 can slide horizontally on the base 1. The feeding drive assembly 42 is installed between the base 1 and the moving seat 41. The feeding drive assembly 42 is used to drive the moving seat 41 to slide horizontally along the base 1, and the moving direction of the moving seat 41 is parallel to the length direction of the supporting roller 12. The height adjustment assembly 43 is installed on the top of the moving seat 41, and the receiving seat 44 is installed on the top of the height adjustment assembly 43, and the height adjustment assembly 43 can vertically adjust the height of the receiving seat 44. The top of the receiving seat 44 is used to temporarily place the steel coil, and the top of the receiving seat 44 is set to a concave shape that matches the bottom of the steel coil. The steel coil clamping assembly 45 is installed on the receiving seat 44, and the steel coil clamping assembly 45 is used to clamp both sides of the steel coil on the receiving seat 44.

[0033] When it is necessary to provide steel coils to the supporting roller 12, the moving seat 41 is first driven to move by the feeding drive component 42 so that the moving seat 41 is located obliquely below the supporting roller 12, and then the steel coil is transported to the receiving seat 44 by a forklift, and the steel coil clamping component 45 is used to clamp both sides of the steel coil so that the steel coil on the receiving seat 44 is not easy to fall off, and then the height of the receiving seat 44 is raised by the height adjustment component 43 so that the center of the steel coil is aligned with the supporting roller 12, and then the feeding drive component 42 adjusts the position of the moving seat 41 so that the steel coil gradually approaches the supporting roller 12 and is finally sleeved on the supporting roller 12, and then the steel coil clamping component 45 releases the clamping of the steel coil, and the position of the moving seat 41 is adjusted again so that the moving seat 41 is away from the supporting roller 12, and then the steel coil is tightened by adjusting the tensioning mechanism 121 so that the supporting roller 12 can drive the steel coil to rotate together.

[0034] Furthermore, the feed drive assembly 42 includes a feed drive member 421, a feed drive gear 422 and a feed drive rack 423. The movable seat 41 is a hollow shell. The feed drive member 421 is fixed to the bottom of the movable seat 41. The feed drive gear 422 is fixed to the output end of the feed drive member 421. The feed drive rack 423 is horizontally fixed to the base 1. The length direction of the feed drive rack 423 is parallel to the length direction of the supporting roller 12. The bottom of the movable seat 41 is provided with an extension port for the feed drive gear 422 to extend out, and the feed drive gear 422 is meshed with the feed drive rack 423. In this embodiment, the feed drive member 421 is a servo motor.

[0035] When the position of the moving seat 41 needs to be adjusted, the feeding drive gear 422 is driven to rotate by the feeding drive member 421. Since the feeding drive gear 422 is meshed with the feeding drive rack 423, the feeding drive gear 422 can move along the length direction of the feeding drive rack 423 during the rotation process to adjust the position of the moving seat 41. In addition, in order to improve the stability of the moving seat 41 during movement, a plurality of rotating wheels are rotatably installed at the bottom of the moving seat 41, and the rotating wheels are in contact with the top of the base 1.

[0036] Preferably, the height adjustment component 43 includes a height adjustment cylinder 431 and a plurality of telescopic rods 432. The height adjustment cylinder 431 is located between the moving seat 41 and the receiving seat 44. The bottom of the height adjustment cylinder 431 is fixed to the inner bottom of the moving seat 41. The piston rod of the height adjustment cylinder 431 is fixed to the bottom of the receiving seat 44. The plurality of telescopic rods 432 are vertically installed between the moving seat 41 and the receiving seat 44, and the plurality of telescopic rods 432 are located around the height adjustment cylinder 431.

[0037] When the height of the receiving seat 44 needs to be adjusted, the piston rod of the height adjusting cylinder 431 is correspondingly extended and retracted to drive the receiving seat 44 to rise or move downward, and the setting of the telescopic rod 432 can limit the lifting and lowering of the receiving seat 44 to improve the stability of the receiving seat 44 when it is lifted and lowered. Since multiple telescopic rods 432 are located around the height adjusting cylinder 431, the receiving seat 44 can also be subjected to a more uniform force, making it less likely to tilt.

[0038] Furthermore, the steel coil clamping assembly 45 includes a steel coil rotating shaft 451, a steel coil swinging shaft 452, a steel coil clamping cylinder 453, a plurality of steel coil clamping arms 454 and an end limit seat 455. The steel coil rotating shaft 451 is provided in two, and the two steel coil rotating shafts 451 are respectively rotatably connected to the two sides of the receiving seat 44. The steel coil rotating shaft 451 is horizontally provided, and the length direction of the steel coil rotating shaft 451 is parallel to the moving direction of the moving seat 41. The steel coil swinging shaft 452 is vertically fixed to the two ends of the steel coil rotating shaft 451, and the steel coil swinging shaft 452 is away from the steel coil rotating shaft One end of the shaft 451 is tilted downward, the steel coil clamping cylinder 453 is horizontally hinged between the two steel coil swing shafts 452, and multiple steel coil clamping arms 454 are vertically fixed on the steel coil rotating shaft 451, and one end of the steel coil clamping arm 454 away from the steel coil rotating shaft 451 is tilted upward. After the steel coil is placed on the receiving seat 44, the multiple steel coil clamping arms 454 can be located on both sides of the steel coil, and the two end limit seats 455 are respectively slidably connected to the opposite ends of the receiving seat 44, and the two end limit seats 455 are respectively located directly above the two steel coil clamping cylinders 453. In this embodiment, the steel coil clamping cylinder 453 is a double piston rod cylinder.

[0039] When the piston rod of the steel coil clamping cylinder 453 is extended, the lower ends of the two steel coil swing shafts 452 will move away from each other, and the two steel coil rotating shafts 451 will rotate in opposite directions at a certain angle, so that the multiple steel coil clamping arms 454 located on both sides of the steel coil are close to each other, and in the process of extending the piston rod of the steel coil clamping cylinder 453, the lower ends of the two steel coil swing shafts 452 will gradually rise, thereby driving the steel coil clamping cylinder 453 to rise a certain distance, and allowing the outer side of the steel coil clamping cylinder 453 to contact the bottom of the end limit seat 455, and drive the end limit seat 455 to rise, so that the end limit seat 455 protrudes from the top of the receiving seat 44, so that the two end limit seats 455 can limit the two ends of the steel coil respectively, so as to improve the stability of the steel coil and prevent it from being easily offset.

[0040] It should be noted that a T-block is vertically fixed to one end of the receiving seat 44 near the end stop seat 455, and a T-slot is vertically opened at one end of the end stop seat 455 near the receiving seat 44, and the T-block is slidably connected to the T-slot. The arrangement of the T-block and the T-slot can limit the sliding of the end stop seat 455, making it more stable when sliding. At the same time, the lateral force exerted on the steel coil will not be transmitted to the steel coil clamping cylinder 453, which plays a certain protective role for the steel coil clamping cylinder 453. In addition, the T-slot runs through the upper end of the receiving seat 44, so that the end stop seat 455 can smoothly protrude from the top of the receiving seat 44.

[0041] Reference Figure 3 Preferably, the supporting mechanism 5 includes a supporting mounting frame 51, a supporting arm 52, a lower articulated arm 53, an upper articulated arm 54, an articulated cylinder 55, a supporting assembly 56 and a sleeve driving cylinder 57. The supporting mounting frame 51 is located on one side of the base 1, and the supporting mounting frame 51 is located on one side of the supporting roller 12. One end of the supporting arm 52 is hinged in the supporting mounting frame 51, and one end of the lower articulated arm 53 is hinged in the supporting mounting frame 51. The lower articulated arm 53 is located below the supporting arm 52, and the upper articulated arm 54 is hinged between the lower articulated arm 53 and the supporting arm 52. One end of the articulated cylinder 55 is articulated to the top of the supporting mounting frame 51, and the other end of the articulated cylinder 55 is articulated to the articulated shaft between the upper articulated arm 54 and the lower articulated arm 53. The sleeve driving cylinder 57 is fixed to the end of the supporting arm 52 away from the supporting mounting frame 51, and the supporting assembly 56 is slidably connected to the top of the supporting arm 52, and the piston rod of the sleeve driving cylinder 57 is connected to the supporting assembly 56. The supporting assembly 56 cooperates with the end of the supporting roller 12 away from the frame 11, so that the supporting assembly 56 can support one end of the supporting roller 12.

[0042] Since the steel coil needs to be put on the supporting roller 12 first before one end of the supporting roller 12 is supported by the supporting mechanism 5, before the steel coil is put on the supporting roller 12, the piston rod of the articulated cylinder 55 is driven to retract, so that the ends of the upper articulated arm 54 and the lower articulated arm 53 that are close to each other are retracted into the supporting mounting frame 51, and the end of the supporting arm 52 away from the supporting mounting frame 51 is swung down, so that the supporting arm 52 will not affect the transfer of the steel coil; after the steel coil is put on the supporting roller 12, the piston rod of the articulated cylinder 55 is driven to extend, so that the end of the supporting arm 52 away from the supporting mounting frame 51 is swung up, so that the supporting assembly 56 is aligned with the supporting roller 12, and then the supporting assembly 56 is pushed horizontally to the supporting roller 12 by the sleeve driving cylinder 57, and cooperates with the supporting roller 12, so that one end of the supporting roller 12 can be stably supported.

[0043] Furthermore, an auxiliary supporting cylinder 511 is horizontally fixed on the supporting mounting frame 51, an auxiliary plug rod 512 is fixed to the end of the piston rod of the auxiliary supporting cylinder 511, an auxiliary slot 531 is opened on the lower articulated arm 53, the auxiliary plug rod 512 is plugged into the auxiliary slot 531, and when the supporting assembly 56 is aligned with the supporting roller 12, the auxiliary plug rod 512 can be aligned with the auxiliary slot 531.

[0044] When the supporting assembly on the supporting arm 52 supports the supporting roller 12, the auxiliary insertion rod 512 can be aligned with the auxiliary slot 531. At this time, the piston rod of the auxiliary supporting cylinder 511 extends to drive the auxiliary insertion rod 512 to be inserted into the auxiliary slot 531 of the lower articulated arm 53, thereby performing a second restriction on the position of the lower articulated arm 53 to share the load borne by the articulated cylinder 55.

[0045] Reference Figure 3 and Figure 4 Preferably, the supporting assembly 56 includes a bearing seat 561 and a supporting bearing 562. The bearing seat 561 is slidably connected to the supporting arm 52. A slider is fixed to the bottom of the bearing seat 561. A slide groove is provided at the top of the supporting arm 52, and the slider is slidably connected to the slide groove. The length direction of the slider and the slide groove is parallel to the length direction of the supporting roller 12. The end of the bearing seat 561 away from the supporting roller 12 is connected to the piston rod of the sleeve driving cylinder 57. The supporting bearing 562 is installed in the bearing seat 561. A plurality of plug-in blocks are fixed to the inner circumferential side of the inner ring of the supporting bearing 562. 5621, a plug-in groove 122 is provided at one end of the supporting roller 12 close to the bearing seat 561, and a plurality of plug-in grooves 122 are arranged circumferentially along the supporting roller 12, and the plug-in grooves 122 are plugged into the plug-in block 5621, and a plurality of flaring grooves 123 are provided at the end of the supporting roller 12, and the number of the flaring grooves 123 is the same as the number of the plug-in grooves 122, and the flaring grooves 123 are connected with the plug-in grooves 122, and the flaring grooves 123 are closer to the supporting bearing 562 than the plug-in grooves 122, and the width of the flaring grooves 123 gradually increases in the direction close to the supporting bearing 562.

[0046] After the inner ring of the supporting bearing 562 in the bearing seat 561 is aligned with the supporting roller 12, the bearing seat 561 is pushed close to the supporting roller 12 by the piston rod of the sleeve driving cylinder 57. Since a plurality of expanding grooves 123 are provided, the plug-in block 5621 can be first inserted into the expanding groove 123, and under the guidance of the expanding groove 123, the inner ring of the supporting bearing 562 is driven to rotate a certain angle to correct the angle of the plug-in block 5621 so that the plug-in block 5621 can be aligned with the plug-in groove 122. Finally, one end of the supporting roller 12 can be inserted into the inner ring of the supporting bearing 562, and the plug-in block 5621 can be inserted into the plug-in groove 122. When the supporting roller 12 rotates, the inner ring of the stripping bearing can be driven to rotate together, thereby supporting one end of the supporting roller 12.

[0047] Reference Figure 5 Furthermore, the lateral limiting mechanism 2 includes a lateral seat 21, a bidirectional lead screw 22, two internally threaded seats 23, a blocking rod 24 and a handwheel 25. The lateral seat 21 is fixed to one side of the frame 11, and the lateral seat 21 is located obliquely above the supporting roller 12. The length direction of the lateral seat 21 is parallel to the length direction of the supporting roller 12, and the bidirectional lead screw 22 is rotatably connected to the lateral seat 21. The length direction of the bidirectional lead screw 22 is parallel to the length direction of the supporting roller 12. The two internally threaded seats 23 are respectively threadedly sleeved on two opposite threaded portions of the bidirectional lead screw 22, and the internally threaded seats 23 are slidably connected to the lateral seat 21. The handwheel 25 is fixedly connected to one end of the bidirectional lead screw 22 so that the bidirectional lead screw 22 can be driven to rotate by the handwheel 25. An articulated seat 231 is installed at one end of the internally threaded seat 23 close to the supporting roller 12, and the blocking rod 24 is hinged on the articulated seat 231. The two blocking rods 24 can block the two ends of the steel coil respectively.

[0048] After the steel coil is installed on the outside of the support roller 12 and the supporting mechanism 5 supports one end of the support roller 12, the blocking rod 24 is rotated to make the blocking rod 24 droop away from one end of the internal thread seat 23, so that the two blocking rods 24 can be respectively located at the two ends of the steel coil, and then the hand wheel 25 is rotated to drive the bidirectional screw 22 to rotate through the hand wheel 25, thereby driving the two internal thread seats 23 to move in opposite directions, so that the two blocking rods 24 are close to each other, so that the two blocking rods 24 can block the two ends of the steel coil respectively, so that the steel coil is not easy to deviate. In addition, in order to limit the drooping angle of the blocking rod 24, a limiting plate is horizontally fixed at the bottom of the articulated seat 231, so that the blocking rod 24 will not droop excessively under the restriction of the limiting plate.

[0049] Preferably, the clamping mechanism 3 includes a swing cylinder 31, a clamping swing shaft 32, a clamping swing arm 33 and a clamping wheel 34. The swing cylinder 31 is mounted on the frame 11. The clamping swing shaft 32 is horizontally mounted on the output end of the swing cylinder 31. The length direction of the clamping swing shaft 32 is parallel to the length direction of the supporting roller 12. The clamping swing arm 33 is fixed on the clamping swing shaft 32. The clamping swing arm 33 is arranged in an arc shape. A plurality of clamping wheels 34 are all horizontally rotated on the clamping swing arm 33, and the clamping wheels 34 are used to clamp the outer side of the steel coil on the supporting roller 12. In addition, an ultrasonic thickness gauge is installed at one end of the lateral seat 21 close to the supporting roller 12, and the detection end of the ultrasonic thickness gauge is aligned with the steel coil on the supporting roller 12. The ultrasonic thickness gauge is electrically connected to a controller, and the swing cylinder 31 is electrically connected to the controller through an electromagnetic valve, and the electromagnetic valve is used to control the air path of the swing cylinder 31.

[0050] The output end of the swing cylinder 31 can drive the clamping swing shaft 32 to rotate a certain angle, so that the lower end of the clamping swing arm 33 swings. Since the clamping swing arm 33 is arranged in an arc shape, and a plurality of clamping wheels 34 are arranged on the clamping swing arm 33, the clamping wheels 34 can contact the outer side of the steel coil, so that the outer side of the steel coil can be clamped to a certain extent, so that the steel coil is not easy to loosen due to its own gravity. The ultrasonic thickness gauge can detect the current thickness of the steel coil on the supporting roller 12. The ultrasonic thickness gauge transmits the data to the controller, and the controller controls the air path of the swing cylinder 31, so that the output end of the swing cylinder 31 can timely adjust the swing amplitude of the clamping swing arm 33 according to the remaining thickness of the steel coil, so that the clamping wheel 34 can smoothly clamp the steel coil.

[0051] The implementation principle of the uncoiler in the embodiment of the present application is as follows: the feeding mechanism 4 is used to temporarily place the steel coil, and the feeding mechanism 4 transports the steel coil placed thereon to the supporting roller 12, the lateral limiting mechanism 2 axially limits the steel coil on the supporting roller 12, so that the steel coil on the supporting roller 12 is not easy to move axially, the clamping mechanism 3 can clamp the outer side of the steel coil, so that the steel coil is not easy to unwind due to its own gravity when uncoiling, and the supporting mechanism 5 can support the other end of the supporting roller 12, so that the force on both ends of the supporting roller 12 is more even, so as to improve the stability of the supporting roller 12 when rotating.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
