Description

Technical Field

[0001] The invention relates to the technical field of steel strip processing devices, and in particular to a steel strip winding looper device. Background Art

[0002] During the processing and production of steel strips, it is usually necessary to further thin the steel strip coils produced by rough rolling through a continuous rolling processing line. Two unwinding and two winding devices are respectively set at the head and tail ends of the continuous rolling processing line to avoid the processing line being forced to stop when changing coils and being unable to run continuously. The double workstations at the head and tail ends of the processing line greatly reduce the time required for coil changing, but a looper device is still required to store and convey the steel strips.

[0003] The looping device currently used in the steel strip processing line is mainly a rail-type looping car. However, the rail-type looping car requires a sufficiently long space to move and occupies a large area. Therefore, this type of looping device is usually installed underground, which is not convenient for workers to repair and maintain. Summary of the invention

[0004] In view of the above, it is necessary for the present invention to provide a looping device with a simple structure and which does not require much space.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A steel strip winding loop device is used for transporting steel strips and storing them at the same time, comprising: a machine base placed on a horizontal plane, with a first arch frame and a second arch frame arranged in a pair on the machine base; a feeding mechanism rotatably arranged on the first arch frame; a steering structure fixedly arranged in the feeding mechanism and extending in the direction of the second arch frame; a winding mechanism rotatably arranged on the second arch frame and connected to the steering structure; a first support frame slidably installed below the winding mechanism; and a second support frame fixedly arranged below the feeding mechanism.

[0007] Furthermore, the feeding mechanism includes a first motor, a limit plate and a feed wheel sleeve. The first motor is installed on the outer side of the first arch frame. The output shaft of the first motor passes through the first arch frame and is connected to the feed wheel sleeve. The limit plate is installed on the first arch frame and is located between the first arch frame and the feed wheel sleeve.

[0008] Furthermore, the feed wheel sleeve includes two mounting rings, a plurality of connecting rollers and an inclined roller. The two mounting rings are spaced apart in the axial direction, and a plurality of circular holes are opened on the two mounting rings at equal intervals. The two ends of the plurality of connecting rollers are respectively inserted into the plurality of circular holes of the two mounting rings; arc grooves are opened on the two mounting rings respectively, and the arc grooves are connected with the plurality of circular holes to form a complete circular ring; sliding blocks are installed in the two arc grooves, and the two sliding blocks are sleeved on the two ends of the inclined roller to connect the inclined roller between the two mounting rings at an angle.

[0009] Furthermore, the feeding mechanism also includes a clamping structure, which includes a clamping shell, a lower pressure rod and a clamping rod. The clamping shell is arranged on a mounting ring close to the limit plate, and the lower pressure rod is movably installed on the clamping shell. One end of the lower pressure rod extends into the clamping shell, and the other end protrudes out of the clamping shell; one end of the clamping rod is arranged in the clamping shell, and the other end is located in the arc groove.

[0010] Furthermore, the lower pressure rod and the clamping rod are both provided with a spring at one end of the clamping shell. The clamping rod is pushed away from the clamping shell by the spring and is pressed against and locked with the limit plate so that the feed wheel sleeve and the limit plate can rotate synchronously. The lower pressure rod and the clamping rod are clamped at one end located in the clamping shell. When the lower pressure rod slides into the clamping shell, the clamping of the clamping rod is released, and the locking of the clamping rod on the limit plate is loosened.

[0011] Furthermore, the steering structure includes a steering shaft, which passes through a feed wheel sleeve. Two support assemblies are radially arranged on the steering shaft, and a steering roller is installed between the two support assemblies. The steel belt rotates around the steering roller for steering and is wound onto a winding mechanism.

[0012] Furthermore, a mounting rod is provided at one end of the steering shaft close to the winding mechanism, and a guide roller is provided at the top end of the mounting rod. The guide roller guides and corrects the steel belt conveyed on the steering roller.

[0013] Furthermore, the winding mechanism includes a winding drum and a winding shaft. The center of the winding drum corresponds to the center of the steering shaft. The winding shaft is connected between the winding drum and the second arch frame. The winding shaft includes a hollow winding shaft head and a plurality of swinging shoes. The winding shaft head is rotatably arranged on the second arch frame. A connecting shaft fixedly connected to the center of the winding drum is arranged at the center of the winding shaft head, which is used to drive the winding drum to rotate synchronously when the winding shaft head rotates.

[0014] Furthermore, several of the swing pads are hinged on the winding shaft head and extend in the direction of the winding reel; and several swing pads are surrounded by the connecting shaft; a sliding sleeve is sleeved on the connecting shaft, and one end of the sliding sleeve is hinged with several pull rods, and each pull rod is hinged with the inner annular surface of each swing pad; the other end of the sliding sleeve is hinged with several foldable connecting rod groups, and the other end of the connecting rod group is hinged with the winding shaft head; each connecting rod group is configured as two connecting rods hinged to each other, and a ball is connected to one end of the two connecting rods that are hinged to each other, and a torsion spring is arranged between the two connecting rods for unfolding the folded connecting rod group.

[0015] Furthermore, the first support frame and the second support frame are both provided with a liftable support assembly, the support assembly is provided with a rotating roller, the rotating roller is connected to a third motor, and the third motor drives the rotating roller to rotate.

[0016] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects:

[0017] 1. When the feeding mechanism is fixed, it is used for the circular conveying of the steel strip and can guide the steel strip to turn for conveying; when the feeding mechanism rotates, it can drive the steel strip to wind while tightening the steel coil stored on the winding mechanism, making it convenient for the winding mechanism to continue to wind and store the steel strip.

[0018] 2. The winding mechanism can be used to store the steel belt while conveying it. The steel in the process of transportation can be wound on the winding mechanism, which solves the problem of large floor space occupied by ordinary looping devices.

DETAILED DESCRIPTION

[0029] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0030] Reference Figure 1-Figure 3 The embodiment of the present invention provides a steel strip winding looper device, including a machine base 1 placed on a horizontal plane, with a first arch frame 11 and a second arch frame 13 erected at both ends of the machine base 1, and a feed frame 12 for assisting in conveying the steel strip is disposed on the first arch frame 11 and the second arch frame 13. Among them, a feeding mechanism 2 is disposed on the first arch frame 11, and a steering structure 3 for changing the conveying direction of the steel strip is disposed at the center of the feeding mechanism 2. The steel strip enters from the feed frame 12 at the end of the feeding mechanism 2, wraps around the feeding mechanism 2 and is conveyed to the steering structure 3 to change the conveying direction. The steering structure 3 protrudes from one end of the feeding mechanism 2 and is connected to a winding mechanism 4, which is mounted on the second arch frame 13. The steel strip conveyed by the steering structure 3 wraps around the winding mechanism 4 for transmission and storage.

[0031] The feeding mechanism 2 includes a first motor 20, a limit plate 21 and a feed wheel sleeve 22. The first motor 20 is installed on the outer side of the first arch frame 11. The output shaft of the first motor 20 passes through the first arch frame 11, extends to the inner side of the first arch frame 11 and is connected to the feed wheel sleeve 22. The limit plate 21 is installed on the first arch frame 11 and is located between the first arch frame 11 and the feed wheel sleeve 22.

[0032] The feeding wheel sleeve 22 includes two mounting rings 221, a plurality of connecting rollers 222 connecting the two mounting rings 221, and an inclined roller 223 for guiding the steel belt to turn. The two mounting rings 221 are arranged at intervals along the axial direction, one of the mounting rings 221 is against the limit plate 21, and a connecting plate is connected to the center, and the connecting plate is sleeved on the output shaft of the first motor 20. A plurality of circular holes are opened at equal intervals on the two mounting rings 221, and the plurality of circular holes are arranged in a "C" shape. The two ends of the plurality of connecting rollers 222 are respectively inserted into the plurality of circular holes of the two mounting rings 221. The inclined roller 223 is obliquely connected between the two mounting rings 21, and the two ends of the inclined roller 223 are respectively sleeved with sliding blocks 2212. Both mounting rings 221 are provided with an arc groove 2211, and the arc groove 2211 is located at the opening where the plurality of circular holes are arranged in a "C" shape; the two sliding blocks 2212 are respectively installed in the two arc grooves 2211. It can be understood that an elastic member is abutted between the sliding block 2212 and the arc groove 2211 , and the sliding block 2212 is reset after sliding in the arc groove 2211 through the elastic member.

[0033] When the feeding mechanism 2 is used to convey the steel belt, the first motor 20 does not drive the limit plate 21 to rotate. The steel belt wraps around the feed wheel sleeve 22 and is tightly attached to a number of connecting rollers 222. The moving steel belt drives the connecting rollers 222 to rotate, reducing the friction force of the steel belt when it moves, and guides the steel belt to the inclined rollers 223. The steel belt revolves around the inclined rollers 223 and turns to the center of the feed wheel sleeve 22.

[0034] Reference Figure 4 , Figure 5 The feeding mechanism 2 is also provided with a clamping structure 23, including a clamping shell 231, a lower pressure rod 232 and a clamping rod 233. The clamping structure 23 presses against the limit plate 21 through the clamping rod 233, thereby clamping the feed wheel sleeve 22 on the limit plate 21. The clamping shell 231 is arranged on the mounting ring 221 that abuts against the limit plate 21 and is close to the sliding block 2212. The lower pressure rod 232 is slidably arranged on the clamping shell 231, one end of the lower pressure rod 232 extends into the clamping shell 231 and is provided with an inclined surface 2321, and the other end protrudes out of the clamping shell 231 and can be pressed by the steel belt to slide into the clamping shell 231. The clamping rod 233 is arranged in an "L" shape, one end of which extends into the clamping shell 231, and the other end is located in the arc groove 2211 and connected to the sliding block 2212. The end of the clamping rod 233 located in the clamping shell 231 is formed with an inclined block 2331 that matches the inclined surface of the pressing rod 232. It can be understood that the pressing rod 232 and the end of the clamping rod 233 extending into the clamping shell 231 are both provided with springs for resetting after moving.

[0035] Specifically, when the feed wheel sleeve 22 is clamped in the limiting disk 21, the lower pressure rod 232 protrudes out of the clamping shell 231, and the clamping rod 233 is pushed away from the clamping shell 231 by the spring and pressed against the limiting disk 21. The lower pressure rod 232 and one end of the clamping rod 233 located in the clamping shell 231 are clamped together, and the clamping rod 233 is locked, so that the clamping rod 233 is always pressed against the limiting disk 21, and the feed wheel sleeve 22 and the limiting disk 21 are locked, so that the feed wheel sleeve 22 and the limiting disk 21 can keep rotating synchronously. When the lower pressure rod 232 is pressed by the steel belt and slides into the clamping shell 231, the lower pressure rod 232 descends relative to the clamping rod 233 in the clamping shell 231, so that the lower pressure rod 232 releases the clamping of the clamping rod 233, thereby releasing the lock between the feed wheel sleeve 22 and the limiting disk 21.

[0036] When the feeding mechanism 2 is used to store the steel strip, the steel strip stops conveying, the first motor 20 drives the limit plate 21 to rotate, and the clamping structure 23 fixes the feed wheel sleeve 22 on the limit plate 21, and rotates synchronously with the limit plate 21. The steel strip is wound on the feed wheel sleeve 22, pressing the lower pressure rod 232 to slide into the clamping shell 231. At the same time, the steel strip rotating on the steering structure 3 is tightened, pulling the inclined roller 223 to move, and the inclined roller 223 drives the sliding block 2212 to slide in the arc groove 2211, and synchronously drives the inclined block of the clamping rod 233 to slide against the inclined surface of the lower pressure rod 232 in the clamping shell 231, so that the clamping rod 233 is away from the limit plate 21 and clamped with the lower pressure rod 232, and the locking between the feed wheel sleeve 22 and the limit plate 21 is released.

[0037] The steel belt enters the center of the feeding wheel sleeve 22 and rotates on the surface of the steering structure 3 to further adjust the conveying direction. The steering structure 3 includes a steering shaft 31. One end of the steering shaft 31 that penetrates the center of the feeding wheel sleeve 22 is set as a conical head, so that the steel belt is spirally wound on the conical head for conveying, which is convenient for steering; the cone tip of the conical head is fixedly connected to the connecting disk, which is used to drive the steering shaft 31 to rotate synchronously when the connecting disk rotates. Two support assemblies 311 are arranged radially on the steering shaft 31, and a steering roller 32 is installed between the two support assemblies 311. After the steel belt is turned by the conical head, it rotates on the steering roller 32 for secondary steering, so that the steel belt conveyed in the horizontal direction is wound on the winding mechanism 4 after turning.

[0038] Furthermore, a mounting rod 312 is provided at one end of the steering shaft 31 away from the conical head, and a guide roller 313 is provided at the top end of the mounting rod 312 . The guide roller 313 guides and corrects the steel belt conveyed on the steering roller 32 .

[0039] Reference Figure 6 , Figure 7The winding mechanism 4 includes a winding disk 41 and a winding shaft 42. The center of the winding disk 41 is connected to the end of the steering shaft 31 away from the conical head. The winding shaft 42 is arranged between the winding disk 41 and the second arch frame 13 on the machine base 1. The winding shaft 42 includes a hollow winding shaft head 421 and a plurality of swinging shoes 422. The winding shaft head 421 is rotatably connected to the second arch frame 13 and is connected to a second motor; the winding shaft 42 is driven to rotate by the second motor, thereby driving the winding disk 41 to rotate. A connecting shaft 423 is arranged at the center of the winding shaft head 421 and is fixedly connected to the center of the winding disk 41, which is used to drive the winding disk 41 to rotate synchronously when the winding shaft head 421 rotates.

[0040] A plurality of swinging tiles 422 are arranged between the winding shaft head 421 and the winding reel 41, and one end of the plurality of swinging tiles 422 is hinged to the winding shaft head 421; and a plurality of swinging tiles 422 surround the outside of the connecting shaft 423. A sliding sleeve 424 is sleeved on the connecting shaft 423, and one end of the sliding sleeve 424 is hinged to a plurality of pull rods 425, and each pull rod 425 is connected to the inner wall surface of each swinging tile 422. The other end of the sliding sleeve 424 is connected to a plurality of foldable connecting rod groups, and each connecting rod group is configured as two connecting rods hinged to each other; one of the connecting rods is hinged to the sliding sleeve 424, and the other connecting rod is hinged to the winding shaft head 421, and a ball is connected to one end of the two connecting rods hinged to each other. It can be understood that a torsion spring is arranged between the two connecting rods of each connecting rod group, which is used to unfold the folded connecting rod group.

[0041] The second motor drives the winding shaft head 421 to rotate, and the winding shaft head 421 drives the winding disk 41 to rotate synchronously through the connecting shaft 423. At the same time, the connecting rod group hinged on the winding shaft head 421 rotates around the connecting shaft 423. Under the action of centrifugal force, the ball arranged on the connecting rod group moves in the direction away from the connecting shaft 423, driving the two connecting rods to approach each other, and then pulling the sliding sleeve 424 to move. The sliding sleeve 424 drives the pulling rod 425 to move synchronously, thereby pulling the swinging shoe 422 to shrink and move closer to each other, so that the steel strip is wound on the shrinking swinging shoe 422 for transportation.

[0042] Reference Figure 1 and Figure 2 The base 1 is also provided with a first support frame 51 and a second support frame 52. The first support frame 51 is horizontally slidable and arranged below the winding shaft 42, and the second support frame 52 is fixed below the feeding mechanism 2. Both ends of the first support frame 51 and the second support frame 52 are provided with a support assembly 53 that can be raised and lowered. The support assembly 53 includes a hydraulic cylinder, and the hydraulic cylinder is connected to a lifting rod, and the lifting rod slides and rises in the hydraulic cylinder. The lifting rod is connected to a rotating roller 54, and one end of the rotating roller 54 is connected to a third motor, and the rotating roller 54 is driven to rotate by the third motor.

[0043] Combination Figure 3The first support frame 51 located below the winding shaft 42 supports the steel coil, the swing shoe 422 shrinks and separates from the center of the supported steel coil, and the rotating roller 54 abuts against the surface of the steel coil. The rotating roller 54 is driven by the third motor to drive the steel coil to rotate synchronously. Since the angular velocity of the steel coil is the same, the linear velocity of the outer circumference of the steel coil is greater than that of the inner circumference, the diameter of the steel coil will slowly increase, and the rotating roller 54 will slowly descend as the diameter of the steel coil increases, so that the steel coil always corresponds to the center of the winding drum 41.

[0044] The second support frame 52 located below the feeding mechanism 2 abuts against the surface of the steel strip when the steel strip is not wound, so that the steel strip is transported closely against the surface of the feed wheel sleeve 22; when the feed wheel sleeve 22 drives the steel strip to be wound, the third motor drives the rotating roller 54 to drive the steel coil to rotate.

[0045] The implementation principle of the winding looper device in the embodiment of the present application is as follows:

[0046] The rough-rolled steel strip enters from the feed frame 12 above the feeding mechanism 2, wraps around the connecting roller 222 of the feed wheel sleeve 22, is transported to the inclined roller 223, and then turns to the center of the feed wheel sleeve 22, and spirally wraps around the conical head of the steering shaft 31. The conical head turns the steel strip for a second time and rotates it around the steering roller 32. The steel strip drives the steering roller 32 to rotate. The steering roller 32 lifts the steel strip and adjusts the conveying direction to convey it to the guide roller 313. The guide roller 313 further changes the conveying direction of the steel strip, so that the steel strip is wound on the winding shaft 42. After the steel strip is wound around the winding shaft 42 for several turns, it penetrates into the feed frame 12 above the winding mechanism 4, and the support assembly 53 located on the first support frame 51 rises to support the steel strip roll, and then the second motor is started to drive the winding shaft 42 to rotate, and synchronously drives the winding disk 41 to rotate;

[0047] The balls arranged on the connecting rod groups pull the two connecting rods closer to each other under the centrifugal force generated when they rotate, driving the sliding sleeve 424 to slide synchronously, and the sliding sleeve 424 pulls the pull rod 425 to drive the swing shoe 422 to move closer to each other, breaking away from the central support of the steel strip coil. At this time, the steel strip coil is completely seated on the support assembly 53 of the first support frame 51 and abuts against the rotating roller 54, and the steel strip wrapped around the swing shoe 422 is transported, and the steel strip at the center of the steel coil is pulled out; when the steel coil rotates, the diameter of the steel coil will gradually increase, and the stored steel strip will gradually increase;

[0048] When the rough-rolled steel coil needs to be replaced at the feeding end, the steel strip on the feeding mechanism 2 stops conveying, and then the steel coil on the winding mechanism 4 stops rotating, and the second motor drives the winding shaft 42 to continuously extract the steel strip in the center of the steel coil for conveying, thereby reducing the stock of the steel strip on the steel coil; after the replacement of the rough-rolled steel coil at the feeding end is completed, the material is fed slowly, so that the steel strip extracted from the winding shaft 42 pulls the steel coil above the first support frame 51 to tighten, thereby reducing the diameter of the steel coil, so that the steel coil with a reduced diameter can continue to store the steel strip, and when the steel coil continues to store material, the feeding speed of the feeding end is restored;

[0049] When the receiving end needs to replace the receiving coil, the winding shaft 42 stops rotating, and the plurality of swing shoes 422 move away from each other. The support assembly 53 on the first support frame 51 descends and slides under the winding shaft head 421, and the steel coil is supported by the swing shoe 422. Then the first motor 20 starts, driving the limit plate 21 and the feed wheel sleeve 22 to rotate synchronously, and the steel belt is wound on the feed wheel sleeve 22. The steering structure 3 rotates synchronously with the limit plate 21, driving the guide roller 313 to rotate around the winding disc 41, and pulling the steel coil on the winding mechanism 4 to be tightened on the winding shaft 42. After the steel coil on the winding shaft 42 is tightened, the steel belt is tightened, pulling the inclined roller 223 to move, driving the sliding block 2212 to slide in the arc groove 2211, and the sliding block 2212 drives the clamping rod 233 to move, so that the inclined block 2331 of the clamping rod 233 slides on the inclined surface 2321 of the lower pressure rod 232 and is clamped, releasing the clamping rod 233 from the limit plate 21, loosening the fixation of the feed shaft sleeve 22 and the limit plate 21, and the feed shaft sleeve 22 moves on the wound steel coil. The steel strip at the center of the steel coil is pulled out and wound on the steel coil of the winding shaft 42. After the steel strip wound on the feed shaft sleeve 22 is pulled out, the steel strip releases the pressure on the lower pressure rod 232, and the lower pressure rod 232 pops out of the clamping shell 231. The inclined surface 2321 of the lower pressure rod 232 rises and disengages from the inclined block 2331 of the clamping rod 233, releasing the clamping of the clamping rod 233, and fixing the feed wheel sleeve 22 on the limit plate 21 again. At the same time, the first motor 20 stops rotating.

[0050] After the receiving end resumes receiving the material, the first support frame 51 slides back under the winding shaft 42 to support the steel coil, and the second motor starts to continue to drive the steel strip to receive the material.

[0051] The winding loop device provided by the present invention conveys the steel strip through a feeding mechanism and changes the conveying direction of the steel strip, and then supports the steel strip to a certain height through a steering structure, so as to facilitate winding the steel strip on the winding mechanism. The steel strip is conveyed and stored while being conveyed by the winding mechanism, so that after the feeding end stops feeding, the stored steel strip is still supplied to the discharging end for operation. The device has a simple structure and occupies a small area, which greatly improves the utilization rate of space resources.

[0052] The above-described embodiments only express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
