Description

Technical Field

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

[0002] After the production of flexible thin steel plates, they are generally wound into steel coils for transfer and temporary storage, and then unwound during use; flexible thin steel plates generally have elastic deformation and plastic deformation. When winding flexible steel plates, special attention should be paid not to exceed this limit. If only elastic deformation occurs during winding, it can basically be flattened after unwinding. Even if no correction is performed, it can return to flatness when placed naturally; however, if significant plastic deformation occurs, quite troublesome steps are required for pressing and straightening.

[0003] For the consideration of the volume and winding efficiency after winding, in actual production, it is still desired that the internal support roller is as small as possible, so that more materials can be wound in a smaller occupied space. Summary of the Invention

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

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a winding mechanism for flexible steel plates, including a main bottom plate, a flexible sensing mechanism, a winding mechanism, and a winding inner diameter adjustment mechanism. The flexible sensing mechanism and the winding mechanism are arranged on the main bottom plate, and the winding inner diameter adjustment mechanism is arranged on the winding mechanism;

[0006] Further, the flexible sensing mechanism includes a pressing support assembly, an elongation extrusion assembly, and a deformation sensing assembly. The pressing support assembly is arranged on the main bottom plate, the elongation extrusion assembly is arranged on the pressing support assembly, and the deformation sensing assembly is arranged on the elongation extrusion assembly.

[0007] The flexible sensing mechanism can sense the flexibility of the flexible steel plate and feedback the result to the winding inner diameter adjustment mechanism through a hydraulic transmission method, so as to automatically calibrate and adjust the minimum winding diameter of the winding mechanism.

[0008] Preferably, the pressing and supporting assembly includes a gantry bracket, a supporting roller, a downward pressing fork bracket and a downward pressing roller. The gantry bracket is fixedly connected to the main bottom plate. The supporting roller is rotatably arranged in the gantry bracket. The downward pressing fork bracket is arranged on the deformation sensing assembly. The downward pressing roller is rotatably arranged in the downward pressing fork bracket.

[0009] As a further preference of the present invention, the elongation and extrusion assembly includes an electric push rod, a guiding ring and a piston plate. The electric push rod is arranged on the gantry bracket. The guiding ring is fixedly connected to the outer shell of the electric push rod. The guiding ring is provided with a guiding hole. The piston plate is arranged at the end of the sliding part of the electric push rod.

[0010] Each time the electric push rod extends by the same amplitude, according to the different rigidity of the flexible steel plate, the sliding amplitude of the piston plate in the liquid storage cavity is also different, and then the amount of liquid entering the rotary pushing box in the liquid storage cavity is also different, so as to realize the detection and feedback output of the flexible steel plate.

[0011] Preferably, the deformation sensing assembly includes a liquid storage cavity, a pressing spring and a hydraulic pipeline. The liquid storage cavity is provided with a guiding rod. The guiding rod is clamped and slidably arranged in the guiding hole. The piston plate is clamped and slidably arranged in the liquid storage cavity. The pressing spring is arranged between the bottom of the liquid storage cavity and the piston plate. One end of the hydraulic pipeline communicates with the liquid storage cavity. The other end of the hydraulic pipeline is provided with a normally closed quick-release joint I.

[0012] Furthermore, the winding mechanism includes a rotary winding assembly and a variable internal support rod assembly. The rotary winding assembly is arranged on the main bottom plate. A plurality of groups of variable internal support rod assemblies are annularly and evenly arranged. The variable internal support rod assembly is slidably arranged in the rotary winding assembly.

[0013] Preferably, the rotary winding assembly includes a winding bracket, a supporting bearing and a winding drum. The winding bracket is arranged on the main bottom plate. The supporting bearing is arranged in the winding bracket. Both ends of the winding drum are provided with round shaft parts. The round shaft parts are arranged in the supporting bearing. End baffles are symmetrically arranged on both sides of the winding drum. The end baffles are annularly and evenly provided with sliding grooves.

[0014] By sliding adjustment of the variable internal support rod assembly, the minimum winding diameter of the winding mechanism can be changed, so that the technical effects of minimizing the minimum bending and reducing the storage volume can be achieved without excessive bending.

[0015] As a further preference of the present invention, the variable internal support rod assembly includes a sliding support rod and a return spring. The sliding support rod is engaged and slidably disposed in the sliding groove. The return spring is disposed between the bottom wall of the sliding groove and the sliding support rod. The flexible steel plate is located between the support roller and the pressing roller, and one end of the flexible steel plate is fixed on one of the sliding support rods.

[0016] Through the elastic force of the return spring, the sliding support rod can be automatically reset to the state closest to the winding drum in the free state, thereby achieving the technical effect that only pulling the limit pawl can automatically reset the ratchet disc and all sliding support rods; by increasing the number of ratchets on the ratchet disc, the adjustment accuracy of the rotation of the ratchet disc on the sliding support rod can be improved.

[0017] Furthermore, the winding inner diameter adjustment mechanism includes a rotation adjustment component, a ratchet type locking component, and a ratchet unlocking component.

The rotary push box is fixedly connected to the circular shaft portion. The rotary push box is provided with a sliding guide portion. The arc-shaped push rod is engaged and slidably disposed in the sliding guide portion. The normally closed quick-release joint II is fixedly connected to the rotary push box. After the normally closed quick-release joint II and the normally closed quick-release joint I are inserted and connected, they can be automatically penetrated, and can be automatically closed after being disassembled.

[0019] Through the cooperation of the normally closed quick-release joint I and the normally closed quick-release joint II, the leakage amount of the liquid during the disassembly and assembly process can be negligible.

[0020] As a further preference of the present invention, the ratchet type locking component includes a ratchet disc, a limit pawl, and a driving gear ring. The ratchet disc is rotatably disposed on the circular shaft portion. The ratchet disc is annularly and evenly provided with inclined sliding grooves. The number of the inclined sliding grooves is equal to that of the sliding grooves. The ratchet disc is further provided with a pushing top plate. When the arc-shaped push rod extends, it can push the pushing top plate. The limit pawl cooperates with the ratchet disc. The limit pawl is provided with elastic ratchets. The limit pawl is further provided with a handle portion. The driving gear ring is fixedly connected to the end baffle.

[0021] Through the limitation of the ratchet disc by the limit pawl, when the test is completed and winding is carried out, the sliding support rod can be locked at the adjusted position.

[0022] As a preference, the ratchet unlocking component includes an unlocking guide rod and a pressing spring. The unlocking guide rod is fixedly connected to the end baffle. The ratchet disc is engaged and slidably disposed on the unlocking guide rod. The pressing spring is disposed between the end of the unlocking guide rod and the ratchet disc.

[0023] The beneficial effects achieved by the present invention with the above structure are as follows:

[0025] (2) The electric push rod extends the same amplitude each time. According to the different rigidities of the flexible steel plates, the sliding amplitude of the piston plate in the liquid storage cavity is also different, and then the amount of liquid entering the rotary push box in the liquid storage cavity is also different, so as to realize the detection and feedback output of the flexible steel plate.

[0026] (3) By sliding adjustment of the variable internal support rod assembly, the minimum winding diameter of the winding mechanism can be changed, so that the technical effect of minimizing the minimum bending and reducing the storage volume can be achieved without excessive bending.

[0027] (4) Through the elastic force of the return spring, the sliding support rod can be automatically reset to the state closest to the winding drum in the free state, so as to realize the technical effect that only pulling the limit pawl can make the ratchet disc and all sliding support rods automatically reset; by increasing the number of ratchets on the ratchet disc, the adjustment accuracy of the rotation of the ratchet disc on the sliding support rod can be improved.

[0028] (5) Through the cooperation of the normally closed quick-release joint one and the normally closed quick-release joint two, the leakage of liquid during disassembly and assembly can be ignored.

[0047] As Figures 1 to 13 shown, the present invention proposes a winding mechanism for a flexible steel plate 28, which includes a main base plate 1, a flexible induction mechanism 2, a winding mechanism 3, and a winding inner diameter adjustment mechanism 4.

[0048] The winding mechanism 3 includes a rotary winding assembly 21 and a variable internal support rod assembly 22. The rotary winding assembly 21 is arranged on the main base plate 1, and several groups of variable internal support rod assemblies 22 are annularly and evenly arranged. The variable internal support rod assembly 22 is slidably arranged in the rotary winding assembly 21.

Sliding grooves 30 are annularly and evenly arranged on the end baffles 29.

[0050] Through the sliding adjustment of the variable internal support rod assembly 22, the minimum winding diameter of the winding mechanism 3 can be changed, so that the technical effects of minimizing the minimum bending and reducing the storage volume can be achieved without excessive bending.

[0051] The variable internal support rod assembly 22 includes a sliding support rod 26 and a return spring 27. The sliding support rod 26 is engaged and slidably disposed in the sliding groove 30. The return spring 27 is disposed 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 pressing roller 11. One end of the flexible steel plate 28 is fixed to one of the sliding support rods 26.

[0052] Through the elastic force of the return spring 27, the sliding support rod 26 can be automatically reset to the state closest to the winding drum 25 in the free state, so as to achieve the technical effect that only pulling the limit pawl 39 can make the ratchet disc 38 and all the sliding support rods 26 automatically reset; by increasing the number of ratchets on the ratchet disc 38, the adjustment accuracy of the rotation of the ratchet disc 38 on the sliding support rod 26 can be improved.

[0053] The winding inner diameter adjusting mechanism 4 includes a rotation adjusting assembly 32, a ratchet type locking assembly 33 and a ratchet unlocking assembly 34. The rotation adjusting assembly 32 is disposed on the rotary winding assembly 21. The ratchet type locking assembly 33 is rotatably disposed on the rotary winding assembly 21. The ratchet unlocking assembly 34 is disposed on the rotary winding assembly 21.

[0054] The rotation adjusting assembly 32 includes a rotary push box 35, an arc-shaped push rod 36 and a normally closed quick-release joint II 37. The rotary push box 35 is fixedly connected to the circular shaft portion 31. The rotary push box 35 is provided with a sliding guiding portion 42. The arc-shaped push rod 36 is engaged and slidably disposed in the sliding guiding portion 42. The normally closed quick-release joint II 37 is fixedly connected to the rotary push box 35. The normally closed quick-release joint II 37 and the normally closed quick-release joint I 18 can be automatically penetrated after being inserted and connected, and can be automatically closed after being disassembled.

[0055] Through the cooperation of the normally closed quick-release joint I 18 and the normally closed quick-release joint II 37, the leakage amount of the liquid during the disassembly and assembly process can be ignored.

[0056] The ratchet type locking assembly 33 includes a ratchet disc 38, a limit pawl 39 and a driving gear ring 46. The ratchet disc 38 is rotatably disposed on the circular shaft portion 31. The ratchet disc 38 is annularly and uniformly provided with inclined sliding grooves 43. The number of the inclined sliding grooves 43 is equal to that of the sliding grooves 30. The ratchet disc 38 is further provided with a pushing top plate 44. The arc-shaped push rod 36 can push the pushing top plate 44 when extending. The limit pawl 39 cooperates with the ratchet disc 38. The limit pawl 39 is provided with elastic ratchets. The limit pawl 39 is further provided with a handle portion 45. The driving gear ring 46 is fixedly connected to the end baffle 29.

[0057] Through the limitation of the ratchet disc 38 by the limit pawl 39, when the test is completed and winding is carried out, the sliding support rod 26 can be locked in the adjusted position.

[0058] The ratchet unlocking assembly 34 includes an unlocking guide rod 40 and a compression spring 41. The unlocking guide rod 40 is fixedly connected to the end baffle 29. The ratchet disc 38 is engaged and slidably arranged on the unlocking guide rod 40. The compression spring 41 is arranged between the end of the unlocking guide rod 40 and the ratchet disc 38.

[0059] The flexible induction mechanism 2 includes a pressing support assembly 5, an elongation extrusion assembly 6, and a deformation induction assembly 7. The pressing support assembly 5 is arranged on the main base plate 1. The elongation extrusion assembly 6 is arranged on the pressing support assembly 5. The deformation induction assembly 7 is arranged on the elongation extrusion assembly 6.

[0060] Through the flexible induction mechanism 2, the flexibility of the flexible steel plate 28 can be sensed, and the result can be fed back to the winding inner diameter adjusting mechanism 4 in a hydraulic transmission manner, so as to automatically calibrate and adjust the minimum winding diameter of the winding mechanism 3.

[0061] The pressing support assembly 5 includes a gantry bracket 8, a support roller 9, a downward pressing fork 10, and a downward pressing roller 11. The gantry bracket 8 is fixedly connected to the main base plate 1. The support roller 9 is rotatably arranged in the gantry bracket 8. The downward pressing fork 10 is arranged on the deformation induction assembly 7. The downward pressing roller 11 is rotatably arranged in the downward pressing fork 10.

[0062] 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 fixedly connected to the housing of the electric push rod 12. A guide hole 19 is arranged on the guide ring 13. The piston plate 14 is arranged at the end of the sliding part of the electric push rod 12.

[0063] Each time the electric push rod 12 extends by the same amplitude. According to the different rigidities of the flexible steel plate 28, the sliding amplitude of the piston plate 14 in the liquid storage cavity 15 is also different, and then the amount of liquid entering the rotary push box 35 from the liquid storage cavity 15 is also different, so as to realize the detection and feedback output of the flexible steel plate 28.

[0064] The deformation induction assembly 7 includes a liquid storage cavity 15, a pressure spring 16, and a hydraulic pipeline 17. A guide rod 20 is arranged on the liquid storage cavity 15. The guide rod 20 is engaged and slidably arranged in the guide hole 19. The piston plate 14 is engaged and slidably arranged in the liquid storage cavity 15. The pressure spring 16 is arranged between the bottom of the liquid storage cavity 15 and the piston plate 14. One end of the hydraulic pipeline 17 communicates with the liquid storage cavity 15, and the other end of the hydraulic pipeline 17 is provided with a normally closed quick-release joint 18.

[0065] During specific use, first, the user needs to place the flexible steel plate 28 on the support roller 9, and then lower the liquid storage cavity 15 by extending the electric push rod 12. After the downward pressing roller 11 contacts the flexible steel plate 28, when the electric push rod 12 continues to extend, the piston plate 14 will generate relative sliding with the liquid storage cavity 15;

[0066] The thrust of the electric push rod 12 is not sufficient to cause excessive deformation of the flexible steel plate 28. When the extension amplitude of the electric push rod 12 is the same, the higher the rigidity of the flexible steel plate 28, the greater the compression amount of the return spring 27, and the more liquid in the liquid storage cavity 15 enters the rotary push box 35 through the hydraulic pipeline 17, and the greater the extension amplitude of the arc-shaped push rod 36 is pushed;

[0067] When the arc-shaped push rod 36 extends, it will push the ratchet disc 38 to rotate by pushing the push top plate 44. When the ratchet disc 38 and the end baffle 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;

[0068] The softer the flexible steel plate 28 is, the smaller the sliding amplitude of the sliding support rod 26 and the smaller the minimum winding diameter; the harder the flexible steel plate 28 is, the greater the sliding amplitude of the sliding support rod 26 and the greater the minimum winding diameter.

[0069] After adjusting the sliding support rod 26, the electric push rod 12 is driven to retract. When the flexible induction mechanism 2 rises and resets, the liquid will flow back through the hydraulic pipeline 17. However, at this time, due to the limitation of the limit pawl 39, the ratchet disc 38 cannot rotate back to reset, and due to the elastic force of the return spring 27, the sliding support rod 26 will still remain in the current position;

[0070] Since both 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 drive the sliding support rod 26 to move closer to the central position, but due to the locking of the ratchet teeth, the sliding support rod 26 cannot contract and move closer, so it can be ensured that the position of the sliding support rod 26 will not change during subsequent winding.

[0071] Then disconnect the connection between the normally closed quick-release joint one 18 and the normally closed quick-release joint two 37. After fixing one end of the flexible steel plate 28 to one of the sliding support rods 26, the entire winding drum 25 can be driven to rotate by an external motor driving the drive gear ring 46, thereby winding the flexible steel plate 28.

[0072] The winding mechanism 3 can be circulated and reused in production. That is to say, after the wound flexible steel plate 28 is used up in the next process, the winding mechanism 3 can wind new materials again;

[0073] At this time, since the material and rigidity of the new material are unknown, pulling the handle part 45 can make the limit pawl 39 slide against the elastic force of the compression spring 41. When the ratchet teeth of the ratchet disc 38 and the limit pawl 39 are separated, the sliding support rod 26 and the ratchet disc 38 will reset under the elastic force of the return spring 27.

[0074] Before winding new materials, after connecting the normally closed quick-release joint one 18 and the normally closed quick-release joint two 37, the above steps can be repeated.

[0075] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0076] The above describes the present invention and its embodiments, and this description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In short, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
