Description

Technical Field

[0001] The present invention relates to the technical field of silicon steel core winding, and specifically, to a silicon steel core winding device and a winding method thereof. Background Art

[0002] The iron core is an important component of various motors and the main component of the motor cost. The annual output of motors is as high as tens of millions, consuming hundreds of thousands of tons of silicon steel for iron cores. The iron core can be used to make the iron cores of various transformers, motors, and generators, and the iron core is usually stacked by hot-rolled or cold-rolled silicon steel with a relatively high silicon content and an insulating paint coated on the surface.

[0003] The patent with the patent publication number CN218585796U discloses an oil-immersed transformer silicon steel core winding machine, including a winding platform. The upper surface of the winding platform is fixedly connected with two groups of motor brackets. Two groups of rotating motors are assembled inside the two groups of motor brackets. The front side of the rotating motor is assembled with a motor disc. Multiple disc grooves are opened inside the motor disc. Multiple threaded through holes are opened inside the disc grooves. A scale is arranged on the right side of the threaded through hole. Compared with the prior art, by setting the disc groove, threaded through hole, scale, hexagon screw, observation hole, indicating needle, iron core winding plate, and sliding plate, during the use of the device, after removing the hexagon screw, the sliding plate is adjusted to an appropriate position according to the scale and the indicating needle, and the hexagon screw is locked and fixed, so that the inner diameter of the wound product can be controlled, solving the problem that the inner diameter of the wound product of the traditional oil-immersed transformer silicon steel core winding machine is inconvenient to control.

[0004] However, there are still deficiencies in the current device: the device can freely control the winding inner diameter of the iron core, but due to the material characteristics, the iron core is prone to slipping during the winding process. At this time, the iron core on the winding roller is prone to deviation, resulting in the iron core gradually separating from the outer wall of the upper layer of the iron core during continuous winding, causing the wound iron core to be a non-regular circle and increasing the risk of spreading. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a silicon steel core winding device and a winding method thereof, solving the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A silicon steel core winding device includes a base. A driving component is arranged on the left side of the top of the base. A motor is arranged on the back of the driving component. A driving roller is arranged on the front of the driving component, and the driving roller is fixedly connected to the output end of the motor. A conveying component is arranged at the center of the top of the base. A plurality of conveying rollers are arranged on the front of the conveying component. A fixing frame is fixedly arranged on the right side of the top of the base. A plurality of jacks are opened inside the fixing frame of the fixing frame, and a winding material roller is arranged inside the jacks of the fixing frame; An anti-deviation device is provided inside the fixing frame. An anti-loosening device is provided above the anti-deviation device. An anti-crease device is provided inside the anti-loosening device. The anti-deviation device includes two electric rotating rods. Both ends of the two electric rotating rods are symmetrically and rotatably installed on the inner wall of the fixing frame. A reciprocating spiral groove is formed on the outer wall of the electric rotating rod. A clamping mesh plate is penetrated and movably installed on the outer wall of the reciprocating spiral groove of the electric rotating rod. A U-shaped groove is formed on the side of the clamping mesh plate away from the axis of the fixing frame. A heating component is fixedly installed on the outer wall of the clamping mesh plate. A friction wheel is rotatably installed at the bottom of the inner wall of the U-shaped groove of the clamping mesh plate. A flow disturbing component is fixedly installed on the top of the friction wheel. A U-shaped heat preservation plate is fixedly installed on the back of the clamping mesh plate located on the back of the fixing frame. A protection plate is penetrated and slidably installed inside the U-shaped heat preservation plate. An inclined plate is hinged to the front of the protection plate through a torsion spring. Start the motor. The output end of the motor drives the driving roller to rotate along the front of the driving component. When the driving roller rotates, the iron core is conveyed to the right. The iron core passes through the adjacent centers of several conveying rollers on the front of the conveying component. The outer wall of the conveying roller starts to rotate due to the frictional force generated by contacting the iron core, converting the sliding friction between the two into rolling friction. Then, the right end of the iron core is clamped into the inner roller gap of the coiling roller. The coiling roller is driven to rotate inside the fixing frame by the output end of an external motor. At the same time, the sockets with different diameters inside the fixed end facilitate the replacement of coiling rollers with different diameters, and are fixed by hexagon bolts to be applicable to coiling rollers with different inner diameters. At the same time, start the two electric rotating rods. The two electric rotating rods rotate in the same direction and the reciprocating spiral grooves on their own outer walls are distributed in the opposite direction. When the electric rotating rods rotate, the clamping mesh plate is restricted by the reciprocating spiral groove on the inner built-in block, so that the electric rotating rods can drive the clamping mesh plates on both sides to move synchronously along the bottom of the inner wall of the fixing frame towards the direction close to the axis of the fixing frame. The clamping mesh plate drives the heating component to move synchronously. Before the material winding work starts, start the heating component. The heating component dissipates heat into the fixing frame through the mesh holes of the clamping mesh plate to preheat the coiling working area. When the clamping mesh plate moves towards the direction close to the axis of the fixing frame, it drives the friction wheel to slide synchronously along the inner wall of the fixing frame. The friction wheel starts to rotate by itself due to the frictional force and drives the flow disturbing component to rotate. The U-shaped heat preservation plate is driven by the clamping mesh plate on the back to move towards the direction close to the axis of the fixing frame. The U-shaped heat preservation plate drives the protection plate to move synchronously. During the movement of the protection plate, it is resisted by the top of the inclined plate. At this time, the hinge shaft of the inclined plate starts to rotate, causing the inclined plate to flip upwards with the hinge shaft as the axis and pushing the protection plate to extend upwards inside the U-shaped heat preservation plate.

[0007] According to the above technical solution, the bottom of the clamping mesh plate is slidably installed on the bottom of the inner wall of the fixing frame. The outer wall of the friction wheel contacts the inner wall of the fixing frame. The bottom of the U-shaped heat preservation plate contacts the top of the right end of the fixing frame. The bottom of the inclined plate is hinged at the edge of the top of the right end of the fixing frame.

[0008] According to the above technical solution, the anti-loosening device includes a transmission plate, a U-shaped frame, a support plate, a telescopic plate, a transmission rod, a pressing roller and a number of elastic arc plates. The top of the transmission plate is hinged to one side of the clamping mesh plate close to the axis of the fixed frame through a torsion spring. The side of the U-shaped frame away from the axis of the fixed frame is hinged to the bottom of the transmission plate. The bottom of the support plate is fixedly installed on the top of the fixed frame. The top of the telescopic end of the telescopic plate is hinged to the top of the inner wall of the support plate. Both ends of the transmission rod are rotatably installed inside the U-shaped frame. The pressing roller penetrates and is fixedly installed on the outer wall of the transmission rod. A number of grooves are formed on the outer wall of the pressing roller. A number of the elastic arc plates are fixedly installed inside the grooves of the pressing roller. When the clamping mesh plate moves towards the axis of the fixed frame, it drives the transmission plate to move synchronously. The transmission plate is restricted by the U-shaped frame, causing its hinge shaft to start rotating. The transmission plate pushes the U-shaped frame downward with the hinge shaft as the axis. At this time, the U-shaped frame pulls the fixed end of the telescopic plate to move downward synchronously. The telescopic plate ensures stability through the limitation of the support plate. Thus, it is ensured that the U-shaped frame can drive the transmission rod to move vertically downward smoothly. The transmission rod drives the pressing roller to move synchronously. When the pressing roller moves downward, it will contact the top of the iron core during the conveying process. At this time, the static pressing roller generates a rotating force through the friction force during the transmission of the top of the iron core. When the pressing roller rotates, it drives the transmission rod and the elastic arc plates to rotate. The elastic arc plates contact the top of the iron core prior to the pressing roller. During the continuous downward movement of the pressing roller, an extrusion force is generated between the elastic arc plates and the top of the iron core, causing deformation. According to the above technical solution, the bottom of the fixed end of the telescopic plate is hinged to the right side of the top of the U-shaped frame, and the arc surface of the elastic arc plate protrudes from the pressing roller.

[0009] According to the above technical solution, the anti-loosening device further includes a U-shaped hollow plate and a number of ductile plates. The bottom of the U-shaped hollow plate on the side away from the axis of the fixed frame is fixedly installed on the inner wall of the fixed end of the telescopic plate. A number of the ductile plates are equidistantly and fixedly installed on the inner wall of the telescopic end of the telescopic plate on the side away from the axis of the fixed frame. The arc surface of one end of the ductile plate close to the axis of the fixed frame is located on the movement track of the top of the U-shaped hollow plate. When the fixed end of the telescopic plate moves downward, it drives the U-shaped hollow plate to move synchronously. When the U-shaped hollow plate moves downward, the top of its inner wall contacts the edge of the arc surface of the top of the ductile plate. Under the pressing of the U-shaped hollow plate, the ductile plate undergoes a bending deformation. When the U-shaped hollow plate passes over the ductile plate through the arc surface guidance, during the process of the ductile plate resetting through its own ductility, it swings reciprocally to generate vibration. And during the swinging process of the ductile plate, it continuously strikes the top of the U-shaped hollow plate to cause the U-shaped hollow plate to resonate. Through the transmission of force, the pressing roller and the elastic arc plates vibrate synchronously.

[0010] According to the above technical solution, the anti-crease device includes a cam, a circular groove plate, a contact circular block, and a friction cotton. The cam penetrates and is fixedly installed on the outer wall of the transmission rod. The outer wall of the circular groove plate away from the axis of the pressing roller is slidably installed on the inner wall of the U-shaped frame. The outer wall of the contact circular block is fixedly installed at the inner edge of the circular groove plate. The outer wall of the friction cotton penetrates and is slidably installed in the circular groove plate through a longitudinal spring. When the transmission rod rotates, it drives the cam to rotate. When the cam rotates, the contact with the contact circular block is released, that is, the contact with the circular groove plate is released. At this time, under the elastic force of the spring horizontally arranged inside the circular groove plate and itself and the U-shaped frame, the circular groove plate can slide along the inner wall of the U-shaped frame towards the pressing roller, and it is urged that the outer wall of the contact circular block is always in contact with the outer wall of the cam. When the cam resets, it pushes the contact circular block and the circular groove plate to reset. Repeating this process urges the circular groove plate to drive the friction cotton to slide back and forth towards the pressing roller and reset, and when the U-shaped frame moves downward, it drives the friction cotton to contact and squeeze the top of the iron core.

[0011] According to the above technical solution, a horizontal spring is arranged between the circular groove plate and the inside of the U-shaped frame. The circular groove plate is located on the left side of the pressing roller. The right side of the outer wall of the contact circular block is in contact with the outer wall of the cam.

[0012] According to the above technical solution, the anti-crease device further includes a limiting rod, a telescopic arc plate, a hook-shaped plate, and a rough plate. The outer wall of the limiting rod is fixedly installed at the center inside the circular groove plate. The bottom of the fixed end of the telescopic arc plate is hinged to the bottom inner wall of the circular groove plate. The arc surface of the outer wall of the fixed end of the telescopic arc plate is in contact with the outer wall of the limiting rod. The arc surface of the telescopic end of the telescopic arc plate is in contact with the outer wall of the pressing roller. The bottom of the right end of the hook-shaped plate is hinged to the top of the telescopic end of the telescopic arc plate through a torsion spring. The bottom of the rough plate is slidably installed on the top of the circular groove plate. The top of the rough plate is hinged to the bottom of the left end of the hook-shaped plate. The circular groove plate drives the telescopic arc plate to move synchronously. The telescopic end of the telescopic arc plate contacts the outer wall of the pressing roller under the push of the circular groove plate to generate a contact force. The telescopic end of the telescopic arc plate contracts towards the inside of its fixed end through the contact force. The limiting rod limits the hinge shaft of the fixed end of the telescopic arc plate to prevent the telescopic arc plate from turning over when scraping the outer wall of the pressing roller. At the same time, when the telescopic end of the telescopic arc plate contracts, it drives the hook-shaped plate to move synchronously. The hook-shaped plate pushes the rough plate to slide along the top of the circular groove plate to increase the friction force, thereby limiting the turning of the telescopic end of the telescopic arc plate.

[0013] A winding method for a silicon steel core winding device includes the following steps: S1: Start the motor. The output end of the motor drives the driving roller to rotate along the front of the driving component. When the driving roller rotates, it conveys the iron core to the right. The iron core passes through the adjacent centers of several conveying rollers on the front of the conveying component. The outer walls of the conveying rollers start to rotate due to the friction force generated by contacting the iron core. S2: Convert the sliding friction between the two into rolling friction, then insert the right end of the iron core into the roller gap inside the coiling roller, and drive the coiling roller to rotate inside the fixed frame through the output end of the external motor. At the same time, the sockets of different diameters inside the fixed end facilitate the replacement of coiling rollers of different diameters, and they are fixed by hexagonal bolts to adapt to coiling rollers of different inner diameters. S3: start two electric rotating rods at the same time, the two electric rotating rods rotate in the same direction and the reciprocating spiral grooves on their outer walls are distributed in opposite directions, so that when the electric rotating rods rotate, the reciprocating spiral grooves restrict the built-in clamping blocks of the clamping mesh plates, so that the electric rotating rods can drive the clamping mesh plates on both sides to move synchronously along the bottom of the inner wall of the fixing frame, toward the axis of the fixing frame; S4: The clamping mesh plate drives the heating component to move synchronously. The heating component is started before the material winding work begins. The heating component dissipates heat to the inside of the fixed frame through the mesh holes of the clamping mesh plate, thereby preheating the coil working area. The present invention provides a silicon steel core winding device and a winding method thereof, which have the following beneficial effects: (1) The present invention sets an anti-deviation device, and cooperates with an electric rotating rod, a clamping mesh plate, a heating component, a friction wheel, a spoiler component, a U-shaped insulation plate, a protective plate and an inclined plate to reduce the internal stress of the iron core by preheating, thereby improving the toughness of the material during winding, avoiding the risk of forced winding increasing the risk of cracks in the material. At the same time, the clamping mesh plate carries heat to clamp and resist the iron core wound on the outer wall of the winding roller, thereby preventing the iron core from slipping due to improper tension control, causing the iron core to gradually separate from the outer wall of the upper layer of the iron core during continuous winding, causing the iron core to deviate during the winding process, and increasing the risk of the winding roller spreading; and the spoiler component is prompted to evenly disperse the disturbed heat flow in the winding area, thereby avoiding the increase in the difficulty of winding due to uneven heating of a part of the material area. At the same time, the protective plate is used to expand the shielding area of ​​the U-shaped insulation plate, effectively reducing the heat loss rate in the winding area, and shielding and protecting the iron core when it breaks during the winding process, thereby avoiding accidental injury to the supervisory staff.

[0014] (2) The present invention sets an anti-loosening device, and cooperates with a clamping mesh plate, a transmission plate, a U-shaped frame, a support plate, a telescopic plate, a transmission rod, a pressing roller, an elastic arc sheet, a U-shaped hollow plate and a tough plate. The elastic arc sheet is used to promote indirect slow contact and pressing between the pressing roller and the iron core, ensuring that the iron core is pressed and tightened by the rotation of the pressing roller after a single winding, so that the iron core can fit closely to each other during the winding process to prevent the stability from being reduced and loosening; at the same time, the elastic arc sheet and the pressing roller are brought into contact with the top of the iron core with the vibration force, so that the two can better fit on the top of the iron core, preventing the vertical downward pressing force from being offset and affecting the winding effect, and at the same time using the vibration force to reduce the adhesion strength of the attachments on the surface of the iron core.

[0015] (3) The present invention sets an anti-crease device, and cooperates with a transmission rod, a cam, a circular groove plate, a resisting round block, friction cotton, a limit rod, a telescopic arc plate, a hook plate and a rough plate. The friction cotton slides back and forth to brush away dirt on the top of the iron core that reduces adhesion, thereby preventing dirt from adhering to the iron core and causing damage when the iron core is wound, and avoiding dents on the inner wall of the iron core that reduce quality. At the same time, when the friction cotton is deformed to the point where only its bottom is in contact with the top of the iron core inside the circular groove plate, the circular groove plate continuously smoothes the top of the iron core when it slides, thereby avoiding the iron core from being continuously transported and raised and bent during the pressing process of the pressing roller, and effectively avoiding the iron core from being creased. At the same time, the arc surface of the telescopic end of the telescopic arc plate is always in contact with the outer wall of the pressing roller. When the arc surface of the telescopic end of the telescopic arc plate contacts the arc surface of the elastic arc sheet, no large shaking will occur under the limitation of the hook plate, thereby ensuring that the pressing roller and the outer wall of the elastic arc sheet always have good cleanliness under the scraping of the telescopic arc plate, thereby avoiding scratches when the pressing roller contacts the iron core.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figures 1 - 9 One embodiment of the present invention is: a silicon steel core winding device, comprising a base 1, a driving assembly 2 is arranged on the left side of the top of the base 1, a motor is arranged on the back of the driving assembly 2, a driving roller 21 is arranged on the front of the driving assembly 2, and the driving roller 21 is fixedly connected to the output end of the motor, a conveying assembly 22 is arranged at the center of the top of the base 1, a plurality of conveying rollers 23 are arranged on the front of the conveying assembly 22, a fixing frame 3 is arranged on the right side of the top of the base 1, a plurality of jacks are opened inside the fixing frame 3, and a coiling roller 31 is arranged inside the jacks of the fixing frame 3; An anti-deviation device 4 is provided inside the fixing frame 3, an anti-loosening device 5 is provided above the anti-deviation device 4, and an anti-crease device 6 is provided inside the anti-loosening device 5; The anti-offset device 4 includes two electric rotating rods 41. Both ends of the two electric rotating rods 41 are symmetrically and rotatably installed on the inner wall of the fixed frame 3. A reciprocating spiral groove is provided on the outer wall of the electric rotating rod 41. A clamping mesh plate 42 is penetrated and movably installed on the outer wall of the reciprocating spiral groove of the electric rotating rod 41. A U-shaped groove is provided on the side of the clamping mesh plate 42 away from the axis of the fixed frame 3. A heating component 43 is fixedly installed on the outer wall of the clamping mesh plate 42. A friction wheel 44 is rotatably installed at the bottom of the inner wall of the U-shaped groove of the clamping mesh plate 42. A flow disturbing component 45 is fixedly installed on the top of the friction wheel 44. A U-shaped heat preservation plate 46 is fixedly installed on the back of the clamping mesh plate 42 located on the back of the fixed frame 3. A protection plate 47 is penetrated and slidably installed inside the U-shaped heat preservation plate 46. An inclined plate 48 is hinged to the front of the protection plate 47 through a torsion spring. Through the above cooperation, the internal stress of the iron core is reduced by preheating, thereby improving the toughness during the winding of the material, avoiding forced winding and increasing the risk of cracks in the material. At the same time, the clamping mesh plate 42 carries heat to clamp and resist the iron core wound on the outer wall of the winding roller 31, avoiding the slipping phenomenon of the iron core due to improper tension control, resulting in the iron core gradually separating from the outer wall of the upper layer of the iron core during continuous winding, causing the offset phenomenon of the iron core during the winding process and increasing the risk of the winding roller spreading; through the above cooperation, the flow disturbing component 45 is prompted to disturb the heat flow to be evenly dispersed in the winding area, avoiding the increase in the winding difficulty due to uneven heat absorption of part of the area of the material. At the same time, relying on the protection plate 47 to expand the shielding area of the U-shaped heat preservation plate 46, effectively reducing the heat loss rate in the winding area, and shielding and protecting during the breakage of the iron core during the winding process, avoiding accidental injury to the supervising staff.

[0020] The bottom of the clamping mesh plate 42 is slidably installed on the bottom of the inner wall of the fixed frame 3. The outer wall of the friction wheel 44 is in contact with the inner wall of the fixed frame 3. The bottom of the U-shaped heat preservation plate 46 is in contact with the top of the right end of the fixed frame 3. The bottom of the inclined plate 48 is hinged to the edge of the top of the right end of the fixed frame 3.

[0021] During use, start the motor. The output end of the motor drives the driving roller 21 to rotate along the front of the driving assembly 2. When the driving roller 21 rotates, it conveys the iron core to the right. The iron core passes through the adjacent centers of several conveying rollers 23 on the front of the conveying assembly 22. The outer wall of the conveying roller 23 starts to rotate due to the frictional force generated by contacting the iron core, converting the sliding friction between the two into rolling friction. Then, the right end of the iron core is clamped into the inner roller gap of the coiling roller 31. The output end of an external motor drives the coiling roller 31 to rotate inside the fixing frame 3. At the same time, the sockets with different diameters inside the fixed end facilitate the replacement of coiling rollers 31 with different diameters, and they are fixed by hexagon bolts to suit coiling rollers with different inner diameters. Meanwhile, start two electric rotating rods 41. The two electric rotating rods 41 rotate in the same direction, and the reciprocating spiral grooves on their outer walls are distributed in opposite directions. When the electric rotating rods 41 rotate, the reciprocating spiral grooves restrict the built-in blocks of the clamping net plate 42, causing the electric rotating rods 41 to drive the clamping net plates 42 on both sides to move synchronously along the bottom of the inner wall of the fixing frame 3 towards the direction close to the axis of the fixing frame 3. The clamping net plate 42 drives the heating assembly 43 to move synchronously. Before the material winding work starts, start the heating assembly 43. The heating assembly 43 dissipates heat into the fixing frame 3 through the mesh holes of the clamping net plate 42 to preheat the winding working area. Through the above cooperation, preheating reduces the internal stress of the iron core, thereby enhancing the toughness during material winding, avoiding forced winding and increasing the risk of cracks in the material. At the same time, the clamping net plate 42 carries heat to clamp and resist the iron core wound on the outer wall of the coiling roller 31, preventing the iron core from slipping due to improper tension control, resulting in the iron core gradually detaching from the outer wall of the upper layer of the iron core during continuous winding, causing the iron core to be misaligned during the winding process and increasing the risk of the coiling roller spreading. When the clamping net plate 42 moves towards the direction close to the axis of the fixing frame 3, it drives the friction wheel 44 to slide frictionally along the inner wall of the fixing frame 3 synchronously. The friction wheel 44 starts to rotate by itself due to the frictional force and drives the flow disturbing assembly 45 to rotate. The clamping net plate 42 located on the back drives the U-shaped heat preservation plate 46 to move towards the direction close to the axis of the fixing frame 3. The U-shaped heat preservation plate 46 drives the protective plate 47 to move synchronously. During the movement of the protective plate 47, it is resisted by the top of the inclined plate 48. At this time, the hinge shaft of the inclined plate 48 starts to rotate, causing the inclined plate 48 to flip upwards with the hinge shaft as the axis, and pushing the protective plate 47 to extend upwards along the inside of the U-shaped heat preservation plate 46. Through the above cooperation, the flow disturbing assembly 45 disturbs the heat flow to be evenly dispersed in the winding area, avoiding the increase in winding difficulty due to uneven heat absorption in some areas of the material. At the same time, relying on the protective plate 47 to expand the shielding area of the U-shaped heat preservation plate 46, effectively reducing the heat loss rate in the winding area, and shielding and protecting during the breakage of the iron core during the winding process, avoiding accidental injury to the supervising staff.

[0022] The anti-loosening device 5 includes a transmission plate 51, a U-shaped frame 52, a support plate 53, a telescopic plate 54, a transmission rod 55, a pressing roller 56 and a number of elastic arc plates 57. The top of the transmission plate 51 is hinged to one side of the clamping mesh plate 42 close to the axis of the fixed frame 3 through a torsion spring. One side of the U-shaped frame 52 away from the axis of the fixed frame 3 is hinged to the bottom of the transmission plate 51. The bottom of the support plate 53 is fixedly installed on the top of the fixed frame 3. The top of the telescopic end of the telescopic plate 54 is hinged to the top inner wall of the support plate 53. Both ends of the transmission rod 55 are rotatably installed inside the U-shaped frame 52. The pressing roller 56 penetrates and is fixedly installed on the outer wall of the transmission rod 55. A number of grooves are formed on the outer wall of the pressing roller 56. A number of elastic arc plates 57 are fixedly installed inside the grooves of the pressing roller 56. Through the above cooperation, the elastic arc plates 57 are relied on to cause the pressing roller 56 to make intermittent and slow contact with the iron core and press, ensuring that the iron core is rotationally pressed and tightened by the pressing roller 56 after each single turn of winding, so that the iron cores during the winding process can be closely attached to each other to prevent the phenomenon of loosening and bursting due to reduced stability. The bottom of the fixed end of the telescopic plate 54 is hinged to the top right side of the U-shaped frame 52, and the arc surface of the elastic arc plate 57 protrudes from the pressing roller 56.

[0023] The anti-loosening device 5 further includes a U-shaped hollow plate 58 and a number of ductile plates 59. The bottom of the U-shaped hollow plate 58 on the side away from the axis of the fixed frame 3 is fixedly installed on the inner wall of the fixed end of the telescopic plate 54. A number of ductile plates 59 on the side away from the axis of the fixed frame 3 are equidistantly and fixedly installed on the inner wall of the telescopic end of the telescopic plate 54. The arc surface of one end of the ductile plate 59 close to the axis of the fixed frame 3 is located on the movement track of the top of the U-shaped hollow plate 58. Through the above cooperation, the elastic arc plate 57 and the pressing roller 56 are caused to contact the top of the iron core with vibration force, enabling the two to better fit on the top of the iron core, preventing the force pressing vertically downward from shifting and affecting the winding effect, and at the same time reducing the adhesion strength of the attachments on the surface of the iron core by means of the vibration force.

[0024] Please refer to Figures 1 - 9 , on the basis of the above embodiments, another embodiment of the present invention further includes an anti-loosening device 5; During use, when the clamping mesh plate 42 moves towards the axis of the fixed frame 3, it drives the transmission plate 51 to move synchronously. The transmission plate 51 is restricted by the U-shaped frame 52, causing its hinge shaft to start rotating. The transmission plate 51 pushes the U-shaped frame 52 downward with the hinge shaft as the axis. At this time, the fixed end of the telescopic plate 54 is pulled synchronously downward by the U-shaped frame 52. The telescopic plate 54 is ensured to be stable through the limit of the support plate 53. Thus, it is ensured that the U-shaped frame 52 can drive the transmission rod 55 to move vertically downward smoothly. The transmission rod 55 drives the pressing roller 56 to move synchronously. When the pressing roller 56 moves downward, it will contact the top of the iron core during transportation. At this time, the static pressing roller 56 generates a rotating force through the friction force during the transmission of the top of the iron core. When the pressing roller 56 rotates, it drives the transmission rod 55 and the elastic arc plate 57 to rotate. The elastic arc plate 57 contacts the top of the iron core earlier than the pressing roller 56. During the continuous downward movement of the pressing roller 56, an extrusion force is generated between the elastic arc plate 57 and the top of the iron core, causing deformation. Through the above cooperation, relying on the elastic arc plate 57, the pressing roller 56 and the iron core are indirectly and slowly contacted and pressed, ensuring that the iron core is rotationally pressed and tightened by the pressing roller 56 after each single turn, so that the iron cores during winding can be closely attached to each other to prevent the stability from decreasing and the phenomenon of loosening and bursting; when the fixed end of the telescopic plate 54 moves downward, it drives the U-shaped hollow plate 58 to move synchronously. When the U-shaped hollow plate 58 moves downward, the top of its inner wall contacts the edge of the arc surface at the top of the resilient plate 59. Under the pressing of the U-shaped hollow plate 58, the resilient plate 59 undergoes a bending deformation. When the U-shaped hollow plate 58 passes over the resilient plate 59 through the arc surface guidance, the resilient plate 59 swings reciprocally and generates vibration during the process of resetting by its own resilience. And during the swinging process of the resilient plate 59, it continuously pats the top of the U-shaped hollow plate 58 to cause the U-shaped hollow plate 58 to resonate. Through the transmission of force, the pressing roller 56 and the elastic arc plate 57 vibrate synchronously. Through the above cooperation, the elastic arc plate 57 and the pressing roller 56 carry the vibration force and contact the top of the iron core, enabling them to better fit on the top of the iron core, preventing the force of vertical downward pressing from shifting and affecting the winding effect, and at the same time reducing the adhesion strength of the attachments on the surface of the iron core by means of the vibration force.

[0025] Please refer to Figures 1 - 9 , on the basis of the above embodiment, in another embodiment of the present invention, a crease prevention device 6 is further included; The anti-crease device 6 includes a cam 61, a circular groove plate 62, a contact circular block 63 and a friction cotton 64. The cam 61 penetrates and is fixedly installed on the outer wall of the transmission rod 55. The outer wall of the circular groove plate 62 away from the axis of the pressing roller 56 is slidably installed on the inner wall of the U-shaped frame 52. The outer wall of the contact circular block 63 is fixedly installed at the inner edge of the circular groove plate 62. The outer wall of the friction cotton 64 penetrates and is slidably installed in the circular groove plate 62 through a longitudinal spring. Through the above cooperation, the dirt with reduced adhesion to the top of the iron core is brushed off by the reciprocating sliding of the friction cotton 64, preventing the phenomenon of knocking damage when the iron core is wound due to dirt adhesion, avoiding the formation of dents on the inner wall of the iron core and reducing the quality. At the same time, when the friction cotton 64 deforms to the point where only its bottom contacts the top of the iron core inside the circular groove plate 62, the circular groove plate 62 continuously smooths the top of the iron core during sliding, avoiding the phenomenon of uplift and bending during the continuous feeding of the iron core during the pressing process of the pressing roller 56, and effectively avoiding the phenomenon of creases on the iron core.

[0026] A transverse spring is arranged between the circular groove plate 62 and the inner part of the U-shaped frame 52. The circular groove plate 62 is located on the left side of the pressing roller 56. The right side of the outer wall of the contact circular block 63 contacts the outer wall of the cam 61.

[0027] The anti-crease device 6 further includes a limiting rod 65, a telescopic arc plate 66, a hook-shaped plate 67 and a rough plate 68. The outer wall of the limiting rod 65 is fixedly installed at the center inside the circular groove plate 62. The bottom of the fixed end of the telescopic arc plate 66 is hinged to the bottom inner wall of the circular groove plate 62. The arc surface of the outer wall of the fixed end of the telescopic arc plate 66 contacts the outer wall of the limiting rod 65. The arc surface of the telescopic end of the telescopic arc plate 66 contacts the outer wall of the pressing roller 56. The bottom of the right end of the hook-shaped plate 67 is hinged to the top of the telescopic end of the telescopic arc plate 66 through a torsion spring. The bottom of the rough plate 68 is slidably installed on the top of the circular groove plate 62. The top of the rough plate 68 is hinged to the bottom left end of the hook-shaped plate 67. Through the above cooperation, the arc surface of the telescopic end of the telescopic arc plate 66 is always in close contact with the outer wall of the pressing roller 56. When the arc surface of the telescopic end of the telescopic arc plate 66 contacts the arc surface of the elastic arc piece 57, it will not shake greatly under the limitation of the hook-shaped plate 67, ensuring that the outer walls of the pressing roller 56 and the elastic arc piece 57 always have good cleanliness under the scraping of the telescopic arc plate 66, and avoiding the phenomenon of scraping damage when the pressing roller 56 contacts the iron core.

[0028] When in use, the transmission rod 55 rotates and drives the cam 61 to rotate. When the cam 61 rotates, the resistance to the abutment round block 63 is released, that is, the resistance to the circular groove plate 62 is contacted. At this time, the circular groove plate 62 can slide along the inner wall of the U-shaped frame 52 toward the pressing roller 56 under the elastic force of the spring arranged laterally inside the U-shaped frame 52, and the outer wall of the abutment round block 63 is always in contact with the outer wall of the cam 61. When the cam 61 is reset, the abutment round block 63 and the circular groove plate 62 are reset. The circular groove plate 62 drives the friction cotton 64 to reciprocate toward the pressing roller 56 direction and reset, and when the U-shaped frame 52 moves downward, it drives the friction cotton 64 to contact and squeeze the top of the iron core. Through the above cooperation, the friction cotton 64 slides back and forth to brush away the dirt on the top of the iron core that reduces the adhesion, so as to prevent the dirt from adhering to the iron core and causing damage when the iron core is wound, and to avoid dents on the inner wall of the iron core that reduce the quality. At the same time, when the friction cotton 64 is deformed to the inside of the circular groove plate 62 where only its bottom is in contact with the top of the iron core, the circular groove plate 62 continuously smoothes the top of the iron core when it slides, so as to avoid the iron core from being continuously transported and bulging during the pressing process of the pressing roller 56. The circular groove plate 62 drives the telescopic arc plate 66 to move synchronously. The telescopic end of the telescopic arc plate 66 contacts the outer wall of the pressing roller 56 under the push of the circular groove plate 62 to generate a resistance force. The telescopic end of the telescopic arc plate 66 contracts toward the inside of its fixed end through the resistance force. The hinge shaft of the fixed end of the telescopic arc plate 66 is limited by the limiting rod 65 to avoid the telescopic arc plate 66 from flipping when scraping the outer wall of the pressing roller 56. At the same time, when the telescopic end of the telescopic arc plate 66 contracts, it drives the hook plate 67 to move synchronously. The hook plate 67 pushes The rough plate 68 slides along the top of the circular groove plate 62 to increase the friction force, thereby flipping and limiting the telescopic end of the telescopic arc plate 66. Through the above cooperation, the arc surface of the telescopic end of the telescopic arc plate 66 is always in contact with the outer wall of the pressing roller 56. When the arc surface of the telescopic end of the telescopic arc plate 66 contacts the arc surface of the elastic arc sheet 57, no large shaking will occur under the limitation of the hook plate 67. Under the scraping of the telescopic arc plate 66, the outer walls of the pressing roller 56 and the elastic arc sheet 57 always have good cleanliness, avoiding scratches when the pressing roller 56 contacts the iron core.

[0029] A winding method for a silicon steel core winding device comprises the following steps: S1: Start the motor, and the motor output end drives the driving roller 21 to rotate along the front of the driving assembly 2. When the driving roller 21 rotates, the iron core is transmitted to the right. The iron core passes through the adjacent centers of several conveying rollers 23 on the front of the conveying assembly 22, and the outer wall of the conveying roller 23 starts to rotate due to the friction generated by contact with the iron core; S2: Convert the sliding friction between the two into rolling friction. Then, snap the right end of the iron core into the internal roll gap of the coiling roller 31, and drive the coiling roller 31 to rotate inside the fixed frame 3 through the output end of the external motor. At the same time, the sockets with different diameters inside the fixed end facilitate the replacement of the coiling rollers 31 with different diameters, and they are fixed by hexagon bolts to accommodate coiling rollers with different inner diameters; S3: Start two electric rotating rods 41 simultaneously. The two electric rotating rods 41 rotate in the same direction, and the reciprocating spiral grooves on their outer walls are distributed in the opposite direction. When the electric rotating rods 41 rotate, the restriction of the built-in blocks of the clamping net plates 42 by the reciprocating spiral grooves enables the electric rotating rods 41 to drive the two-sided clamping net plates 42 to move synchronously along the bottom of the inner wall of the fixed frame 3 towards the direction close to the axis of the fixed frame 3; S4: The clamping net plates 42 drive the heating components 43 to move synchronously. Before the material coiling work starts, start the heating components 43. The heating components 43 dissipate heat into the fixed frame 3 through the mesh holes of the clamping net plates 42 to preheat the coiling work area.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
