Description

Technical Field

[0001] The invention belongs to the technical field of flexible steel plate rolling, and specifically refers to a rolling mechanism for a flexible steel plate. Background Art

[0002] After production, flexible thin steel plates are generally rolled into steel coils for circulation and temporary storage, and then unfolded when used. Flexible thin steel plates generally have elastic deformation and plastic deformation. When rolling up flexible steel plates, special attention should be paid to not breaking this limit. If only elastic deformation occurs during winding, it can basically be flattened after unfolding, and even without correction, it can be restored to flatness by natural placement; but if large-scale plastic deformation occurs, it requires quite troublesome steps to flatten and correct it.

[0003] However, considering the volume and efficiency after winding, in actual production, it is still hoped that the internal support roller is as small as possible, so that more material can be wound in a smaller space. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a winding mechanism for a flexible steel plate, which can automatically adjust the diameter of the central reel of the equipment according to the hardness of the flexible thin steel plate; generally speaking, for a flexible thin steel plate, the higher the hardness, the smaller the degree of bendability, and at this time it can only be rolled up with a relatively large bending radius; the lower the hardness, the greater the degree of bendability, and at this time it can be rolled up with a relatively small bending radius; based on this principle, the present invention detects and feeds back the softness of the material through a flexible sensing mechanism, and after the detection is completed, automatically adjusts and sets the winding inner diameter of the winding mechanism through a winding inner diameter adjustment mechanism; and after the adjustment is completed, the position of the sliding support rod is limited to the state that has been adjusted, and it will not change during the subsequent winding process.

The winding bracket 23 is arranged on the main base plate 1, the support bearing 24 is arranged in the winding bracket 23, and circular shaft portions 31 are arranged at both ends of the winding drum 25. The circular shaft portion 31 is arranged in the support bearing 24. End baffles 29 are also symmetrically arranged on both sides of the winding drum 25, and sliding grooves 30 are evenly distributed in an annular manner on the end baffles 29.

[0035] By sliding adjustment of the variable internal support rod assembly 22, the minimum winding diameter of the winding mechanism 3 can be changed, thereby achieving the technical effect of minimizing the minimum bending and reducing the storage volume without excessive bending.

[0036] The variable internal support rod assembly 22 includes a sliding support rod 26, a return spring 27 and a flexible steel plate 28. The sliding support rod 26 is slidably arranged in the sliding groove 30. The return spring 27 is arranged between the bottom wall of the sliding groove 30 and the sliding support rod 26. The flexible steel plate 28 is located between the support roller 9 and the lower pressure roller 11. One end of the flexible steel plate 28 is fixed on one of the sliding support rods 26.

[0037] Through the elastic force of the reset spring 27, the sliding support rod 26 can be automatically reset to the state closest to the winding drum 25 in a free state, thereby achieving the technical effect of automatically resetting the ratchet plate 38 and all the sliding support rods 26 by only pulling the limit pawl 39; by increasing the number of ratchets on the ratchet plate 38, the adjustment accuracy of the sliding support rod 26 due to the rotation of the ratchet plate 38 can be improved.

[0038] The winding inner diameter adjustment mechanism 4 includes a rotation adjustment component 32, a ratchet locking component 33 and a ratchet unlocking component 34. The rotation adjustment component 32 is arranged on the rotating winding component 21, the ratchet locking component 33 is rotatably arranged on the rotating winding component 21, and the ratchet unlocking component 34 is arranged on the rotating winding component 21.

[0039] The rotation adjustment assembly 32 includes a rotation push box 35, an arc-shaped push rod 36 and a normally closed quick-release joint 37. The rotation push box 35 is fixedly connected to the round shaft portion 31. A sliding guide portion 42 is provided on the rotation push box 35. The arc-shaped push rod 36 is slidably engaged in the sliding guide portion 42. The normally closed quick-release joint 37 is fixedly connected to the rotation push box 35. The normally closed quick-release joint 37 and the normally closed quick-release joint 18 can automatically penetrate after being plugged in and can automatically close after being disassembled.

[0040] Through the cooperation of the normally closed quick-release connector 18 and the normally closed quick-release connector 2 37, the leakage of liquid during the disassembly and assembly process can be ignored.

[0041] The ratchet locking assembly 33 includes a ratchet disk 38, a limiting pawl 39 and a driving gear ring 46. The ratchet disk 38 is rotatably arranged on the circular shaft portion 31. The ratchet disk 38 is annularly evenly provided with inclined sliding grooves 43. The number of the inclined sliding grooves 43 and the sliding grooves 30 are equal. The ratchet disk 38 is also provided with a pushing top plate 44. The arc-shaped push rod 36 can push the pushing top plate 44 when extended. The limiting pawl 39 cooperates with the ratchet disk 38. The limiting pawl 39 is provided with an elastic ratchet. The limiting pawl 39 is also provided with a handle portion 45. The driving gear ring 46 is fixedly connected to the end baffle 29.

[0042] By limiting the position of the ratchet plate 38 by the limiting pawl 39, the sliding support rod 26 can be locked in the adjusted position when the test is completed and the winding is carried out.

[0043] The ratchet unlocking assembly 34 includes an unlocking guide rod 40 and a compression spring 41 . The unlocking guide rod 40 is fixed to the end baffle 29 . The ratchet plate 38 is slidably engaged on the unlocking guide rod 40 . The compression spring 41 is disposed between the end of the unlocking guide rod 40 and the ratchet plate 38 .

[0044] The flexible sensing mechanism 2 includes a pressing support component 5, an elongating and squeezing component 6 and a deformation sensing component 7. The pressing support component 5 is arranged on the main base plate 1, the elongating and squeezing component 6 is arranged on the pressing support component 5, and the deformation sensing component 7 is arranged on the elongating and squeezing component 6.

[0045] The flexibility of the flexible steel plate 28 can be sensed by the flexible sensing mechanism 2 , and the result is fed back to the winding inner diameter adjustment mechanism 4 by means of hydraulic transmission, so as to automatically calibrate and adjust the minimum winding diameter of the winding mechanism 3 .

[0046] The pressing support assembly 5 includes a gantry bracket 8, a supporting roller 9, a pressing fork frame 10 and a pressing roller 11. The gantry bracket 8 is fixedly connected to the main base plate 1, the supporting roller 9 is rotatably arranged in the gantry bracket 8, the pressing fork frame 10 is arranged on the deformation sensing assembly 7, and the pressing roller 11 is rotatably arranged in the pressing roller 11.

[0047] The elongation extrusion assembly 6 includes an electric push rod 12, a guide ring 13 and a piston plate 14. The electric push rod 12 is arranged on the gantry bracket 8. The guide ring 13 is fixed to the outer shell of the electric push rod 12. The guide ring 13 is provided with a guide hole 19. The piston plate 14 is arranged at the end of the sliding part of the electric push rod 12.

[0048] The electric push rod 12 extends the same amplitude each time. According to the different rigidities of the flexible steel plate 28, the sliding amplitude of the piston plate 14 in the liquid storage chamber 15 is also different, which causes the amount of liquid in the liquid storage chamber 15 entering the rotating push box 35 to be different, thereby realizing the detection and feedback output of the flexible steel plate 28.

[0049] The deformation sensing component 7 includes a liquid storage chamber 15, a pressure spring 16 and a hydraulic pipeline 17. The liquid storage chamber 15 is provided with a guide rod 20, which is slidably engaged in the guide hole 19. The piston plate 14 is slidably engaged in the liquid storage chamber 15. The pressure spring 16 is arranged between the bottom of the liquid storage chamber 15 and the piston plate 14. One end of the hydraulic pipeline 17 is connected to the liquid storage chamber 15, and the other end of the hydraulic pipeline 17 is provided with a normally closed quick-release connector 18.

[0050] When in use, the user first needs to place the flexible steel plate 28 on the supporting roller 9, and then extend the electric push rod 12 to bring the liquid storage chamber 15 down. After the lower pressing roller 11 contacts the flexible steel plate 28, the piston plate 14 and the liquid storage chamber 15 will slide relative to each other when the electric push rod 12 continues to extend. The thrust of the electric push rod 12 is not enough to cause excessive deformation of the flexible steel plate 28, so that when the extension range of the electric push rod 12 is the same, the higher the rigidity of the flexible steel plate 28, the greater the compression of the return spring 27, the more liquid in the liquid storage chamber 15 enters the rotating push box 35 through the hydraulic pipe 17, and the arc push rod 36 is pushed to extend to a greater extent; When the arc-shaped push rod 36 extends, it pushes the top plate 44 to push the ratchet plate 38 to rotate. When the ratchet plate 38 and the end baffle plate 29 rotate relative to each other, the sliding support rod 26 can be pushed in a direction away from the center of the winding drum 25. At this time, each group of sliding support rods 26 expands synchronously to limit the minimum diameter during winding. The softer the flexible steel plate 28 is, the smaller the sliding range of the sliding support rod 26 is and the smaller the minimum winding diameter is; the harder the flexible steel plate 28 is, the larger the sliding range of the sliding support rod 26 is and the larger the minimum winding diameter is.

[0051] After the adjustment of the sliding support rod 26 is completed, the electric push rod 12 is driven to retract. When the flexible sensing mechanism 2 rises and resets, the liquid will flow back through the hydraulic pipe 17. However, at this time, due to the limit of the limit pawl 39, the ratchet plate 38 cannot rotate and reset, and due to the elastic force of the reset spring 27, the sliding support rod 26 will still remain in the current position; Due to the elastic force of the return spring 27 and the pressure of the flexible steel plate 28 on the sliding support rod 26 during winding, the sliding support rod 26 is driven toward the center position, but due to the locking of the ratchet, the sliding support rod 26 cannot shrink closer, thereby ensuring that the position of the sliding support rod 26 will not change during the subsequent winding process.

[0052] Then disconnect the connection between the normally closed quick-release joint 18 and the normally closed quick-release joint 2 37, and after fixing one end of the flexible steel plate 28 on one of the sliding support rods 26, the winding drum 25 can be driven to rotate as a whole by driving the driving gear ring 46 through an external motor, thereby winding the flexible steel plate 28.

[0053] The winding mechanism 3 can be circulated and reused in production, that is, after the rolled flexible steel plate 28 is used in the next process, the winding mechanism 3 can rewind new materials; At this time, since the material and rigidity of the new material are unknown, the limit pawl 39 can be pulled by pulling the handle portion 45 to overcome the elastic force of the compression spring 41 and slide. When the ratchet plate 38 and the ratchet teeth of the limit pawl 39 are separated, the sliding support rod 26 and the ratchet plate 38 will be reset under the elastic force of the reset spring 27.

[0054] Before winding a new material, the normally closed quick release connector 18 and the normally closed quick release connector 2 37 are connected, and the above steps can be repeated.

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0056] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
