Description

Technical Field

[0001] This invention relates to the field of silicon steel production technology, and in particular to a silicon steel annealing deviation correction mechanism. Background Technology

[0002] Silicon steel sheet is a soft magnetic alloy of silicon and iron with extremely low carbon content. It generally contains 0.5% to 4.5% silicon. Adding silicon can increase the resistivity and maximum permeability of iron, and reduce coercivity, core loss and magnetic aging. After the silicon steel sheet undergoes the annealing process, a deviation correction mechanism is used to ensure stable winding.

[0003] A coiling device for manufacturing silicon steel sheet coils has been published with application number 202121335058.3. This device can drive the movable baffle to move through the set adjustment mechanism, so that the coiling roller can block both ends of the steel coil when coiling the silicon steel sheet coil, thereby ensuring that no deviation occurs during the coiling process, so as to achieve a better coiling effect.

[0004] This device can only provide conventional guidance for silicon steel during use. However, the silicon steel tends to sag due to its own weight during movement, causing the silicon steel sheets to gradually deviate from their intended path. This leads to subsequent processes being unable to correct the deviation, damaging the equipment, and affecting the normal production of the annealing line. Therefore, a silicon steel annealing deviation correction mechanism is proposed to address the above problems. Summary of the Invention

[0009] In one embodiment of the present invention, a groove is provided on one side of each of the two clamping plates adjacent to each other. A lead screw is rotatably installed on the inner sidewall of the groove. The other end of the lead screw passes through the transmission groove and is fixedly installed with a gear. The gear meshes with a rack. A transmission block is fixedly installed on the outer wall of the lead screw located in the groove. One end of the transmission block extends out of the groove and is fixedly installed with a straightening plate.

[0010] In one embodiment of the present invention, two sets of the corrective plates are provided, and the two sets of corrective plates are symmetrically distributed. A wear-resistant layer is provided on one side of each adjacent set of corrective plates. A sliding groove is provided on one side of each adjacent clamping plate. A sliding block is slidably installed in the sliding groove. One end of the sliding block extends out of the sliding groove and is fixedly connected to one side of the outer wall of the corrective plate.

[0011] In one embodiment of the present invention, a limiting groove is formed in the positioning frame, a limiting block is slidably installed in the limiting groove, a limiting rod is fixedly installed at the top of the limiting block, the top of the limiting rod passes through the positioning frame and is fixedly installed with a pressing plate, and the top of the limiting block is elastically connected to the inner sidewall of the limiting groove through a first spring.

[0012] In one embodiment of the present invention, a protective block is fixedly installed on the side of the correction frame away from the clamping plate. Two sets of protective blocks are provided, and the two sets of protective blocks are symmetrically distributed. A protective groove is opened on the adjacent side of the two sets of protective blocks, and the pressure sensor is fixedly installed in the protective groove.

[0013] In one embodiment of the present invention, a guide rod is fixedly installed on the top of the base, and the top end of the guide rod passes through the clamping plate and is fixedly installed with a knob.

[0014] In one embodiment of the present invention, a positioning plate is fixedly installed on the top of the base, and two sets of positioning plates are provided. An auxiliary groove is opened on the side of the positioning plate near the correction frame. An auxiliary plate is fixedly installed on the inner side wall of the auxiliary groove. One side of the auxiliary plate is elastically connected to the inner side wall of the auxiliary groove through a second spring. A stop button is installed on the inner bottom wall of the auxiliary plate.

[0015] In one embodiment of the present invention, limit rings are fixedly installed on both sides of the outer wall of the take-up roller, and the outer wall of the limit rings is provided with a wear-resistant layer.

[0016] In one embodiment of the present invention, the pressing plate is configured as an arc shape, and a soft material is adhered to the inner sidewall of the pressing plate.

[0017] The technical solution of the present invention has the following advantages compared with the prior art:

[0018] 1. This invention, through the setting of a pressure sensor and an adjustment mechanism, activates a first motor on the positioning frame to drive the winding roller to rotate. The winding roller drives the coiled material, i.e., silicon steel sheet, to wind up. As the silicon steel sheet moves, if the silicon steel sheet deviates, it will press against the pressure sensor. The pressure sensor controls a second motor installed on the correction frame through an electrically connected controller, causing the second motor to drive a double-headed threaded rod to rotate. This causes the double-headed threaded rod to drive two threaded sleeves to move closer together, causing the clamping plates to apply a certain pressure to the silicon steel sheet. This reduces the winding speed of the silicon steel sheet. At this time, the worker can correct the deviation of the silicon steel sheet, or keep the two clamping plates close together. This allows the two clamping plates to cooperate with the winding roller, keeping the silicon steel sheet in a taut state, thus avoiding deviation caused by the silicon steel sheet falling and ensuring the stability of winding.

[0019] 2. This invention, through the arrangement and cooperation of grooves, lead screws, gears, transmission blocks, and straightening plates, facilitates linkage with two clamping plates. Specifically, as the two clamping plates approach each other to clamp or apply pressure to the silicon steel sheet, the rack gradually passes through the transmission groove. The rack meshes with the gear located within the transmission groove, causing the rack to drive the gear to rotate. The gear then drives the lead screw to rotate, which in turn moves the transmission block on it. The transmission block then moves the straightening plate. The two straightening plates move synchronously with the two clamping plates, pushing the misaligned silicon steel sheet back to its correct posture before clamping it. Similarly, the two straightening plates and the two clamping plates can form a stable guiding and straightening structure, continuously straightening the silicon steel sheet.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0028] Please see Figures 1-5 As shown, a silicon steel annealing deviation correction mechanism includes a base 1; a positioning frame 2 is fixedly installed on one side of the top of the base 1, and a take-up roller 3 is rotatably installed on the inner side wall of the positioning frame 2 via a drive rod. A coil of material 4 is wound on the take-up roller 3. A correction frame 5 is fixedly installed on the other side of the top of the base 1. A correction groove is opened on one side of the correction frame 5, and a pressure sensor 7 is installed on one side of the correction frame 5.

[0029] The correction frame 5 is provided with an adjustment mechanism 8. The adjustment mechanism 8 includes an adjustment groove 81 opened in the correction frame 5. A double-ended threaded rod 82 is rotatably connected to the inner bottom wall of the adjustment groove 81. Both ends of the outer wall of the double-ended threaded rod 82 are fixedly connected to threaded sleeves 83. A through groove 84 communicating with the adjustment groove 81 is opened on one side of the correction frame 5. One end of the threaded sleeve 83 extends out of the through groove 84 and is fixedly connected to a clamping plate 85.

[0030] During operation, the device can only provide conventional guidance for silicon steel. However, the silicon steel tends to sag due to its own weight during movement, causing it to gradually deviate from its intended path. This leads to subsequent processes being unable to correct the deviation, damaging equipment, and affecting normal production on the annealing line. Therefore, this deviation correction mechanism is employed. Specifically, through the setting of pressure sensor 7 and adjustment mechanism 8, the first motor on the positioning frame 2 is activated, driving the winding roller 3 to rotate. The winding roller 3 drives the coiled material 4, i.e., the silicon steel sheet, to wind up. As the silicon steel sheet moves, two pressure sensors 7 on the correction frame 5 detect its movement. If the silicon steel sheet deviates, it will press against pressure sensor 7. When the pressure sensor 7 experiences pressure exceeding a predetermined threshold, the controller electrically connected to it controls the second motor installed on the correction frame 5, causing the second motor to drive the double-ended screw... The rotation of the threaded rod 82 causes the double-headed threaded rod 82 to drive the two threaded sleeves 83 closer together. This, in turn, causes the two threaded sleeves 83 to drive the two clamping plates 85 closer together, clamping the silicon steel sheet which is still moving despite its offset. A certain pressure is applied to the silicon steel sheet, reducing its winding speed. At this point, the worker can correct the silicon steel sheet's deviation or keep the two clamping plates 85 close together, allowing them to cooperate with the winding roller 3, keeping the silicon steel sheet taut. This prevents deviation caused by the silicon steel sheet falling, ensuring winding stability. This solves the problem that the device can only provide conventional guidance for the silicon steel, which can fall due to its own weight during movement, causing the silicon steel sheet to gradually deviate, making it impossible to correct in subsequent processes, damaging the equipment, and affecting the normal production of the annealing line.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, racks 9 are fixedly installed on one side of each of the two clamping plates 85, and transmission grooves 10 adapted to racks 9 are opened on one side of each of the two clamping plates 85. Anti-slip protrusions are provided on one side of each of the two clamping plates 85.

[0032] During operation, the rack 9 and the transmission groove 10 are arranged so that the rack 9 passes through the transmission groove 10, thereby preventing the single clamping plate 85 from shifting along with the silicon steel sheet, which would cause damage to the adjustment mechanism 8 and ensure the stability of the positioning mechanism.

[0033] Furthermore, such as Figure 1 and Figure 3As shown, each of the two clamping plates 85 has a groove 11 on one of its adjacent sides. A lead screw 12 is rotatably mounted on the inner wall of the groove 11. The other end of the lead screw 12 passes through the transmission groove 10 and is fixedly mounted with a gear 13. The gear 13 meshes with the rack 9. A transmission block 14 is fixedly mounted on the outer wall of the lead screw 12 located in the groove 11. One end of the transmission block 14 extends out of the groove 11 and is fixedly mounted with a straightening plate 15.

[0034] During operation, the groove 11, lead screw 12, gear 13, transmission block 14, and straightening plate 15 are arranged and coordinated to facilitate linkage with the two clamping plates 85. As the two clamping plates 85 approach each other to clamp or apply pressure to the silicon steel sheet, the rack 9 gradually passes through the transmission groove 10. The rack 9 meshes with the gear 13 located in the transmission groove 10, causing the rack 9 to drive the gear 13 to rotate. The gear 13 then drives the lead screw 12 to rotate, which in turn drives the transmission block 14 to move. The transmission block 14 then drives the straightening plate 15 to move. The two straightening plates 15 and the two clamping plates 85 move synchronously, pushing the misaligned silicon steel sheet back to the correct posture before clamping it. Similarly, the two straightening plates 15 and the two clamping plates 85 can form a stable guiding and straightening structure to continuously straighten the silicon steel sheet. However, considering the service life of the adjusting mechanism 8 and the straightening plate 15, they should not be used for extended periods; they are only used for straightening when misalignment occurs.

[0035] Furthermore, such as Figure 1 and Figure 3 As shown, there are two sets of the correction plates 15, and the two sets of correction plates 15 are symmetrically distributed. A wear-resistant layer is provided on one side of each of the two sets of correction plates 15. A sliding groove 16 is provided on one side of each of the two clamping plates 85. A sliding block 17 is slidably installed in the sliding groove 16. One end of the sliding block 17 extends out of the sliding groove 16 and is fixedly connected to one side of the outer wall of the correction plate 15.

[0036] During operation, the sliding groove 16 and sliding block 17 provide guidance and support for the straightening plate 15, preventing the straightening plate 15 and transmission block 14 from breaking or being damaged due to excessive pressure during the straightening of silicon steel sheets. Both sets of straightening plates 15 have wear-resistant layers on adjacent sides to increase service life.

[0037] Furthermore, such as Figure 2 As shown, a limiting groove 18 is provided in the positioning frame 2, a limiting block is slidably installed in the limiting groove 18, a limiting rod 19 is fixedly installed at the top of the limiting block, the top of the limiting rod 19 passes through the positioning frame 2 and is fixedly installed with a pressing plate 20, and the top of the limiting block is elastically connected to the inner side wall of the limiting groove 18 through a first spring 21.

[0038] During operation, the setting and cooperation of the limiting groove 18, limiting block, limiting rod 19, pressing plate 20 and first spring 21 facilitate the pressing of the wound silicon steel sheet and prevent it from becoming loose. That is, the feeding pressing plate 20 drives the limiting block to move upward through the limiting rod 19. At the same time, the limiting block applies pressure to the first spring 21, that is, one end of the silicon steel sheet is fixed on the winding roller 3. The pressing plate 20 presses the silicon steel sheet under the elastic force of the first spring 21.

[0039] Furthermore, such as Figure 1 and Figure 4 As shown, a protective block 22 is fixedly installed on the side of the correction frame 5 away from the clamping plate 85. There are two sets of protective blocks 22, and the two sets of protective blocks 22 are symmetrically distributed. A protective groove is opened on the adjacent side of the two sets of protective blocks 22. The pressure sensor 7 is fixedly installed in the protective groove.

[0040] During operation, the two protective blocks 22 prevent the silicon steel sheet from shifting beyond a certain angle, thus avoiding irreversible damage to the pressure sensor 7. The protective blocks 22 can protect the pressure sensor 7 from excessive pressure.

[0041] Furthermore, such as Figure 1 As shown, a guide rod 23 is fixedly installed on the top of the base 1, and the top end of the guide rod 23 passes through the clamping plate 85 and is fixedly installed with a knob;

[0042] During operation, the guide rod 23 facilitates the positioning and support of the two clamping plates 85, preventing breakage at the connection between them and the threaded sleeve 83.

[0043] Furthermore, such as Figure 1 As shown, a positioning plate 24 is fixedly installed on the top of the base 1. There are two sets of positioning plates 24. An auxiliary groove is opened on the side of the positioning plate 24 near the correction frame 5. An auxiliary plate 25 is fixedly installed on the inner wall of the auxiliary groove. One side of the auxiliary plate 25 is elastically connected to the inner wall of the auxiliary groove through a second spring. A stop button 26 is installed on the inner bottom wall of the auxiliary plate 25.

[0044] During operation, through the setting and coordination of the auxiliary plate 25, the second spring and the stop button 26, the stop button 26 is electrically connected to the first motor. That is, the auxiliary plate 25 is used for auxiliary positioning to avoid damage to the pressure sensor 7, failure of the adjustment mechanism 8 to operate normally, the auxiliary plate 25 is squeezed and rotated by the offset silicon steel sheet, which then applies pressure to the stop button 26, thereby stopping the first motor from rotating and avoiding further losses.

[0045] Furthermore, such as Figure 2As shown, limit rings 27 are fixedly installed on both sides of the outer wall of the winding roller 3, and the outer wall of the limit rings 27 is provided with a wear-resistant layer.

[0046] During operation, the setting of the limit ring 27 facilitates the positioning and winding of the silicon steel sheet, further ensuring the stability of the winding.

[0047] Furthermore, such as Figure 1 As shown, the pressing plate 20 is arc-shaped, and a soft material is pasted on the inner side wall of the pressing plate 20.

[0048] During operation, the pressing plate 20 is set in an arc shape to facilitate the bonding of the rolled silicon steel sheet. The inner sidewall of the pressing plate 20 is covered with a soft material to reduce wear on the outer wall of the silicon steel sheet.

[0049] Working principle: The first motor on the starting positioning frame 2 drives the winding roller 3 to rotate, which in turn drives the coiled material 4, i.e., the silicon steel sheet, to be wound up. As the silicon steel sheet moves, the movement of the silicon steel sheet is detected by two pressure sensors 7 on the correction frame 5. If the silicon steel sheet deviates, it will press against the pressure sensor 7. When the pressure sensor 7 is subjected to pressure exceeding a predetermined threshold, the controller connected electrically controls the second motor installed on the correction frame 5, causing the second motor to drive the double-headed threaded rod 82 to rotate, thereby causing the double-headed threaded rod 82 to rotate. 2. The two threaded sleeves 83 are brought closer together, which in turn causes the two clamping plates 85 to move closer together and clamp the silicon steel sheet, which is still moving despite being offset. A certain pressure is applied to the silicon steel sheet, which reduces the winding speed of the silicon steel sheet. At this time, the worker can correct the silicon steel sheet, or keep the two clamping plates 85 close together, so that the two clamping plates 85 cooperate with the winding roller 3, so that the silicon steel sheet is in a taut state, which can avoid the offset caused by the silicon steel sheet falling and ensure the stability of winding. Groove 11, screw 1 2. The arrangement and cooperation of gear 13, transmission block 14, and straightening plate 15 facilitates linkage with the two clamping plates 85. That is, as the two clamping plates 85 approach each other to clamp or apply pressure to the silicon steel sheet, rack 9 gradually passes through transmission groove 10. Rack 9 meshes with gear 13 located in transmission groove 10, causing rack 9 to drive gear 13 to rotate. Gear 13 then drives lead screw 12 to rotate. The rotation of lead screw 12 drives transmission block 14 to move, which in turn drives straightening plate 15 to move. The two straightening plates 15 then move together. The positive plate 15 moves synchronously with the two clamping plates 85, pushing the offset silicon steel sheet back to the correct posture before clamping it. Similarly, the two correcting plates 15 and the two clamping plates 85 can form a stable guiding and correcting structure to continuously correct the silicon steel sheet. The auxiliary plate 25 is used for auxiliary positioning to avoid damage to the pressure sensor 7, failure of the adjusting mechanism 8 to operate normally, and the auxiliary plate 25 being squeezed and rotated by the offset silicon steel sheet, which then applies pressure to the stop button 26, thereby stopping the first motor from rotating and preventing further losses.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
