[0038] The present invention provides a device for coiling silicon steel sheets after longitudinal shearing.

[0039] Please refer to Figures 1 to 12The device for coiling silicon steel sheets after longitudinal shearing comprises a winding assembly 1, wherein the winding assembly 1 comprises a transversely arranged bearing rod 11 and a transmission assembly 12 for driving the bearing rod 11 to rotate along its own axial direction. The outer wall of the bearing rod 11 is detachably provided with a winding assembly 2 for winding the silicon steel sheet. The winding assembly 2 comprises a winding drum 21 slidably sleeved on the outer wall of the bearing plate. The outer wall of the winding drum 21 is recessed to form at least one first receiving hole 21a. A transmission plate 22 is slidably provided in the first receiving hole 21a. One end of the transmission plate 22 extends out of the first receiving hole 21a, and the other end is located in the first receiving hole 21a. A clamping plate 23 is provided at one end of the transmission plate 22 extending out of the first receiving hole 21a. The extension direction of the clamping plate 23 is the same as that of the first receiving hole 21a. The axial directions of the winding drum 21 are in the same direction, and the side edges of the splint 23 are connected to the transmission plate 22. A rack 26 is provided on the side edges of the transmission plate 22 along the extension direction of the transmission plate 22. A gear 24 meshing with the rack 26 is also provided in the first receiving hole 21a. The gear 24 is used to drive the transmission plate 22 to move toward or away from the first receiving hole 21a through the rack 26. The two sides of the gear 24 in the axial direction are respectively connected to the first receiving hole 21a for rotation through the first rotating rod 25. The winding assembly 2 also includes a rotating assembly 3 for driving any one of the first rotating rods 25 to rotate so that the splint 23 moves unidirectionally toward the side close to the winding drum 21. The rotating assembly 3 is detachably connected to the first rotating rod 25.

[0040] In the technical solution of the present invention, the cross-section of the inner wall of the winding drum 21 and the cross-section of the bearing rod 11 are both polygonal, the pressure plate is an arc-shaped structure, and the side of the pressure plate close to the winding drum 21 and the side of the winding drum 21 close to the pressure plate are both provided with an anti-slip layer. The arc-shaped pressure plate can better fit with the winding drum 21 to clamp and fix the silicon steel sheet. After the silicon steel sheet is longitudinally sheared, one end of the silicon steel sheet is placed on the side of the clamping plate 23 close to the winding drum 21, and then the rotating assembly 3 is rotated so that the rotating assembly 3 drives the first rotating rod 25 to rotate, and the first rotating rod 2 The rotation of the gear 24 drives the gear 24 to rotate, and the gear 24 rotates in mesh with the rack 26, so that the transmission plate 22 moves toward the side close to the first receiving hole 21a, so that the clamping plate 23 moves toward the side close to the outer wall of the winding drum 21, thereby clamping the silicon steel sheet. Since the rotating assembly 3 can only rotate in one direction, it can also prevent the silicon steel sheet from loosening, further improving the fixing stability of the silicon steel sheet. Through the mutual cooperation between the above structures, the silicon steel sheet can be clamped and fixed, and the silicon steel sheet can be prevented from loosening during the winding process.

[0041] Please refer to the attached Figure 3-4The transmission plate 22 has a through-slot 22a extending transversely therethrough. The through-slot 22a extends in the same direction as the first receiving hole 21a. Multiple limiting rods 27 are slidably disposed within the through-slot 22a. The limiting rods 27 are arranged in the same direction as the first receiving hole 21a, and both ends of the limiting rods 27 are fixedly connected to the wall of the first receiving hole 21a. The interaction between the limiting rods 27 and the through-slot 22a limits the movement direction of the transmission plate 22. Furthermore, the multiple limiting rods 27 prevent the transmission plate 22 from deflecting about a single limiting rod 27.

[0042] Please refer to the attached Figure 5-6 The side wall of the winding drum 21 is recessed to form a rotating hole 31 that communicates with the first receiving hole 21a. The rotating assembly 3 includes a second rotating rod 32 rotatably arranged in the rotating hole 31, one end of the second rotating rod 32 is connected to the first rotating rod 25 in the first receiving hole 21a, and the other end is recessed to form a first insertion hole 33. The side of the rotating hole 31 facing away from the first receiving hole 21a is laterally recessed to form a receiving groove 34. The rotating assembly 3 also includes an insertion rod 35 that can be detachably inserted into the first insertion hole 33, and one end of the insertion rod 35 is provided with an annular fixing block 36. After the fixing block 36 is inserted into the first insertion hole 33 through the insertion rod 35, the fixing block 36 can be located in the receiving groove 34. The outer ring wall of the fixing block 36 is surrounded by spacing distributions with positioning components 39 that cooperate with the groove wall of the receiving groove 34 to enable the fixing block 36 to rotate in a directional manner. The cross-section of the insertion rod 35 of the first insertion hole 33 is polygonal, which can prevent the insertion rod 35 from rotating in the first insertion hole 33. When the fixing block 36 is located in the receiving groove 34, the insertion rod 35 can drive the second rotating rod 32 to rotate by rotating the fixing block 36. The rotation of the second rotating rod 32 can drive the first rotating rod 25 to rotate. The rotation of the first rotating rod 25 can drive the gear 24 to rotate. The rotation of the gear 24 can drive the transmission plate 22 to move toward the side of the bottom of the first receiving hole 21a close to the first receiving hole 21a through mutual engagement with the rack 26. The outer wall of the second rotating rod 32 protrudes with a first limit block 38 for limiting the position of the second rotating rod 32. The positioning assembly 39 fixes the rotation direction of the fixing block 36 to prevent the fixing block 36 from reversing, causing the silicon steel sheet clamped by the clamping plate 23 to loosen.

[0043] Please refer to the attached Figure 6-8The outer wall of the fixing block 36 is clearance-matched with the inner wall of the receiving groove 34. The fixing block 36 and the receiving groove 34 are both annular. The positioning assembly 39 includes a plurality of second receiving holes 391 distributed around the outer ring wall of the fixing block 36. The inner wall of the receiving groove 34 is distributed around the plurality of second plug holes 399. Each of the second receiving holes 391 can correspond to each of the second plug holes 399 one by one, so that the opening of the second receiving hole 391 is connected to the opening of the second plug hole 399. An insert block 392 is slidably provided in each of the second receiving holes 391. The second Grooves 393 are formed on both sides of the hole wall of the receiving hole 391, and sliders 395 for sliding in the grooves 393 are respectively provided on both sides of the insert block 392 close to one end of the second receiving hole 391. A spring 394 is provided on the side of the slider 395 close to the bottom of the second receiving hole 391. The spring 394 is used to drive the end of the insert block 392 away from the bottom of the second receiving hole 391 to extend out of the second receiving hole 391. The two sides of the end of the insert block 392 away from the bottom of the second receiving hole 391 are symmetrically inclined to form a first inclined surface 396, and the other side is a straight surface. The fixing block 36 is provided with a screw hole on the side facing away from the insertion rod 35. The fixing block 36 can be rotated by inserting a tool into the screw hole. When the fixing block 36 is rotated, the first inclined surface 396 of the insertion block 392 will conflict with the hole wall of the second insertion hole 399, so that the insertion block 392 enters the second receiving hole 391. As the fixing block 36 rotates, when the insertion block 392 passes through the second insertion hole 399, the spring 394 drives the insertion block 392 to enter the second insertion hole 399, and so on and so forth to realize the rotation of the fixing block 36. When the reversal direction of the fixing block 36 is the straight surface of the insertion block 392, the straight surface of the insertion block 392 is positioned to conflict with the hole wall of the second insertion hole 399, and the insertion block 392 cannot enter the second receiving hole 391, thereby preventing the fixing block 36 from reversing.

[0044] Please refer to the attached Figure 5 and 8 A push rod 37 is provided on the side of the winding drum 21 facing away from the rotating hole 31, and is slidably provided therethrough. One end of the push rod 37 is located on the side of the winding drum 21 facing away from the rotating hole 31, and the other end is located in the first insertion hole 33. The push rod 37 is used to push the insertion rod 35 toward the side facing away from the first insertion hole 33. The side of the insertion block 392 closer to the winding drum 21 is inclined to form a second inclined surface 397, and the side of the insertion block 392 facing away from the winding drum 21 is inclined to form a third inclined surface 398. The push rod 37 pushes the insertion rod 35 toward the side facing away from the first insertion hole 33. As the insertion rod 35 moves, the third inclined surface 398 abuts against the bottom of the second insertion hole 399, further forcing the insertion block 392 into the second receiving hole 391 and moving the fixing block 36 away from the receiving slot 34. At this point, the second rotating rod 32 can rotate in the opposite direction, thereby loosening the silicon steel sheet and removing it from the clamping plate 23.

[0045] Please refer to the attached Figure 4 The outer wall of the winding drum 21 is formed with a plurality of first receiving holes 21a. The plurality of first receiving holes 21a are spaced apart and arranged in the same direction as the extension direction of the receiving drum. The plurality of first receiving holes 21a have the same structure. A third rotating rod 8 is provided between each pair of the first receiving holes 21a, and both ends of the third rotating rod 8 are connected to the first rotating rod 25 in the first receiving hole 21a in a one-to-one manner. The plurality of third rotating rods 8 are located in the same axial extension direction. When there are multiple first receiving holes 21a, the push rod 37 sequentially passes through the plurality of third rotating rods 8 and is connected to the first insertion hole 33. When there are multiple first receiving holes 21a, the third rotating rod 8 can connect the first rotating rods 25 in the plurality of first receiving holes 21a in series, and the rotating fixed block 36 can drive the plurality of third rotating rods 8 to rotate together, thereby causing the transmission plates 22 in the plurality of first receiving holes 21a to move synchronously.

[0046] Please refer to the attached Figure 9-10 The outer walls of both ends of the winding drum 21 are each provided with a sliding ring plate 5. The ring plate 5 is provided with at least one limiting slider 6 near the inner wall of the winding drum 21. A limiting slot 21b is formed in the outer wall of the receiving drum for the limiting slider 6 to slide. The limiting slot 21b extends in the same direction as the axis of the winding drum 21. A bolt 7 is provided on the same side of the limiting slot 21b as the drum mouth of the winding drum 21. The bolt 7 passes through the outer wall of the winding drum 21 and is rotatably connected to the limiting slider 6. The bolt 7 extends in the same direction as the limiting slot 21b. The side of the winding drum 21 is hollowed out to form multiple hollow holes 21c to reduce the weight of the winding drum 21. By rotating the bolt 7, the ring plate 5 can be moved along the outer wall of the receiving drum and positioned. The ring plate 5 can determine the position of the silicon steel sheet winding. By adjusting the position of the ring plate 5, the ring plate 5 can be adapted to silicon steel sheets of various widths.

[0047] Please refer to the attached Figure 1The transmission assembly 12 includes a base plate 123, on which two first support rods 122 are detachably provided vertically. The carrying rod 11 is rotatably provided between the two first support rods 122 and is detachably connected to the first support rods 122. A motor 121 for driving the carrying rod 11 to rotate is provided on the side of any one of the first support rods 122 facing away from the other first support rod 122, and the output end of the motor 121 is rotatably connected to the carrying rod 11. The motor 121 drives the carrying rod 11 to rotate, thereby achieving the function of driving the carrying rod 11 to rotate. Since the carrying rod 11 is detachably connected to the first support rods 122 and the motor 121, the carrying rod 11 can be removed from the first support rods 122, thereby achieving the disassembly of the winding assembly 2.

[0048] Please refer to the attached Figure 1 and 11 -12, the base plate 123 is also provided with a tension component 4 for bending the silicon steel sheet, the tension component 4 includes at least one group of conveying members arranged below the supporting rod 11, the conveying member includes two active rollers 41 distributed up and down and extending in the same direction, the two active rollers 41 are used to drive the silicon steel sheet to pass through, the two ends of the rotating rollers are respectively fixed to the base plate 123 by a second support rod 42, a driven roller 43 is provided on one side of the conveying member, the two ends of the driven roller 43 are respectively connected to the base plate 123 by a lifting mechanism 44, and the extension directions of the driven roller 43, the active roller 41 and the supporting rod 11 are in the same direction. The two active rollers 41 drive the silicon steel sheet to move toward the side close to the driven roller 43, so that the silicon steel sheet is located above the driven roller 43, and then the lifting mechanism 44 drives the driven roller 43 to move toward the side away from the substrate 123, while driving the silicon steel sheet to bend. The silicon steel sheet subsequently driven by the active roller 41 will conflict with the driven roller 43, causing the silicon steel sheet to deform, adjusting the tension of the silicon steel sheet so that the silicon steel sheet meets the tension requirements of winding.

[0049] Please refer to the attached Figure 1 The winding assembly 1 further includes a speed monitoring module for monitoring the rotational speed of the support rod 11. The speed monitoring module is electrically connected to the motor 121 and the active roller 41. The speed monitoring module monitors the rotational speed of the support rod 11 and controls the rotation of the motor 121 and the active roller 41 to ensure that the rotational speed of the active roller 41 is consistent with that of the support rod 11. If the rotational pace of the support rod 11 and the active roller 41 is inconsistent, silicon steel sheets are likely to accumulate between the material guiding and slitting, and between the slitting and winding sections, and the silicon steel sheets are easily deformed, thus affecting the winding of the silicon steel sheets.
