Description

Technical Field

[0001] This utility model relates to the field of coil winding technology for microcrystalline iron cores, specifically a winding machine for the production of microcrystalline iron cores. Background Technology

[0002] During the manufacturing process of microcrystalline iron core coils, they need to be wound into smaller coils for subsequent installation and use. The winding machine plays a crucial role in this process, primarily responsible for uniformly and tightly winding large coils of wire into smaller coils that meet specifications, ensuring the continuity, integrity, and consistency of the coils. The winding machine consists of several parts, including a wire supply system, a winding head, a tension control system, a guiding device, a cutting and fixing device, and a control system. The wire is continuously supplied from the spool, guided by the guiding device to the winding head, and the electrically driven winding head winds the wire along a predetermined path to form coils. The tension control system ensures that the wire maintains stable tension during winding, preventing the coils from becoming loose or too tight. As the winding process progresses, the coils are stacked layer by layer to form the desired length. Once the preset length is reached, an automatic cutting device cuts the wire and secures the coil to prevent deformation. However, in current winding machines, operators need to guide the microcrystalline iron core coil from the large unwinding drum and onto the small take-up shaft. At this point, operators need to pre-wrap several turns of coil on the take-up shaft to facilitate subsequent winding. Manually winding several turns of coil on the take-up shaft is time-consuming and labor-intensive, especially in mass production environments. This step becomes a bottleneck restricting overall production efficiency. Each wire needs to be wound manually step by step. Improper operation or uneven speed may result in loose coil winding, affecting the continuity and stability of subsequent automatic winding. Furthermore, non-standard initial winding complicates the subsequent automatic winding process. Uneven, loose, or kinked coil winding can lead to wire jamming, loose winding, or even machine stoppage during automatic winding, increasing the possibility of production interruptions. Utility Model Content

[0003] The purpose of this invention is to provide a winding machine for producing microcrystalline iron cores. A large-size coil drum is fixed on an unwinding roller, and the coil end passes sequentially through a lower guide roller, a support roller, and an elastic pressure structure before finally being pulled to the winding roller. A self-tightening wire clamp then limits the coil end to the winding roller. A stepper motor is controlled via a control panel, and the stepper motor drives the winding roller to quickly wind the coil through a belt drive structure until it is wound into a small-size coil drum and tightly packaged. The packaged coil drum is then removed from the winding roller, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a winding machine for producing microcrystalline iron cores, comprising an L-shaped frame, an unwinding roller rotatably mounted on the inner wall of one side of the L-shaped frame, a lower wire guide roller rotatably mounted on the inner wall of the L-shaped frame on the side of the unwinding roller, and a flat plate fixed on the inner wall of the L-shaped frame above the lower wire guide roller. A wire support roller is rotatably mounted on one side of the surface of the flat plate, and an elastic wire pressing structure is mounted on the outer wall of the flat plate above the wire support roller. A winding roller is rotatably mounted on the outer wall of one side of the flat plate, one end of the winding roller extending through to the outside of the L-shaped frame. A recess is provided on the outer wall of the winding roller, and a self-tightening wire clamp is installed inside the winding roller. A stepper motor for driving the lower wire guide roller to rotate is mounted on one side of the bottom of the L-shaped frame. A belt drive structure for power transmission is installed between the lower wire guide roller and the winding roller. A control panel electrically connected to the input end of the stepper motor is mounted on the inner wall of one side of the L-shaped frame.

[0005] Preferably, a pneumatic pressing structure is installed at the bottom of the L-shaped frame on one side of the lower wire feeding roller. The pneumatic pressing structure includes a cylinder installed at the bottom of the L-shaped frame, a C-shaped bearing fixed at the top of the cylinder piston rod, and a side support shaft rotatably installed inside the C-shaped bearing. The central axis of the side support shaft is parallel to the central axis of the lower wire feeding roller, and the input end of the cylinder is electrically connected to the output end of the control panel.

[0006] Preferably, the elastic pressure structure includes a swing arm hinged to one side of the outer wall of the flat plate, an upper pressure roller rotatably mounted on one side of the outer wall of the swing arm, and a tension spring hanging on one side of the outer wall of the flat plate, with one end of the tension spring being connected to one side of the outer wall of the swing arm.

[0007] Preferably, the self-tightening wire clamp includes a U-shaped clamp rod that is installed through the inside of the winding roller and an I-shaped bushing fixed at one end to the surface of the winding roller. One end of the U-shaped clamp rod extends through to the outside of the winding roller and is detachably mounted with a baffle plate. A helical spring is fitted on the outer circumference of the U-shaped clamp rod between the baffle plate and the I-shaped bushing plate.

[0008] Preferably, the baffle and one end of the U-shaped clamp are screwed together.

[0009] Preferably, the U-shaped clamp is made of stainless steel.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This winding machine for producing microcrystalline iron cores uses a structure consisting of an unwinding roller, a lower guide roller, a wire support roller, an elastic pressure structure, a winding roller, and a self-tightening wire clamp to fix a large-size coil drum on the unwinding roller. The coil end passes sequentially through the lower guide roller, the wire support roller, and the elastic pressure structure, and is finally pulled to the winding roller. Then, the self-tightening wire clamp limits the coil end to the winding roller, thus eliminating the need for manual initial winding of the coil. Subsequently, the stepper motor is controlled by the control panel, and the stepper motor drives the winding roller to quickly wind the coil through a belt drive structure until it is wound into a small-size coil drum, which is then cut, bundled, and packaged. The lower guide roller, the wire support roller, the elastic pressure structure, and the self-tightening wire clamp ensure that the wire end can be guided to a predetermined position and firmly clamped. The automatic winding system eliminates the need for manual initial winding of the wire ends, saving workers' time and preventing issues like loose wire ends, insufficient winding, or slippage caused by improper manual operation. The stable guidance of the wire ends ensures the tightness and neatness of the coil layers, providing a reliable foundation for subsequent automatic winding. Secondly, the self-tightening wire clamp limits the wire ends, effectively ensuring their fixation during winding and reducing the possibility of loosening, slippage, or detachment. This ensures the coil remains stable during high-speed winding, preventing uneven winding or wire breakage caused by loose wire ends. Finally, a stepper motor controlled by the control panel drives the winding rollers via a belt drive structure, enabling high-speed, continuous winding of the coil without manual intervention. This ensures the stability and consistency of the winding speed, reducing human error and achieving a highly efficient production rhythm. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of a winding machine for producing microcrystalline iron cores, comprising an L-shaped frame 1, an unwinding roller 2 rotatably mounted on the inner wall of one side of the L-shaped frame 1, a lower wire guide roller 4 rotatably mounted on the inner wall of the L-shaped frame 1 on one side of the unwinding roller 2, and a flat plate 3 fixed on the inner wall of the L-shaped frame 1 above the lower wire guide roller 4. A wire support roller 7 is rotatably mounted on one side of the surface of the flat plate 3, and an elastic wire pressing structure 8 is mounted on the outer wall of the flat plate 3 above the wire support roller 7. A winding roller 9 is rotatably mounted on the outer wall of one side of the flat plate 3, one end of the winding roller 9 extending through to the outside of the L-shaped frame 1, and a [missing information - likely a design feature] is provided on the outer wall of the winding roller 9. The recessed part 901 has a self-tightening wire clamp 10 installed inside the winding roller 9. A stepper motor 6 for driving the lower wire guide roller 4 to rotate is installed on one side of the bottom of the L-shaped frame 1. A belt drive structure 11 for power transmission is installed between the lower wire guide roller 4 and the winding roller 9. The drive shaft of the stepper motor 6 directly drives the lower wire guide roller 4 to rotate. Then, the lower wire guide roller 4 drives the unwinding roller 2 and the winding roller 9 to rotate synchronously and in the same direction through the synchronous pulley and belt. At this time, the coil released by the unwinding roller 2 is wound up by the winding roller 9. A control panel 12 that is electrically connected to the input end of the stepper motor 6 is installed on the inner wall of one side of the L-shaped frame 1.

[0019] A pneumatic pressing structure 5 is installed at the bottom of the L-shaped frame 1 on one side of the lower wire feeding roller 4. The pneumatic pressing structure 5 includes a cylinder installed at the bottom of the L-shaped frame 1, a C-shaped bearing fixed at the top of the cylinder piston rod, and a side support shaft rotatably installed inside the C-shaped bearing. The central axis of the side support shaft is parallel to the central axis of the lower wire feeding roller 4. The input end of the cylinder is electrically connected to the output end of the control panel 12. When the coil passes through the lower wire feeding roller 4 and the pneumatic pressing structure 5 and enters the elastic pressing structure 8 and the wire support roller 7, the operator can control the cylinder in the pneumatic pressing structure 5 through the control panel 12 to work. The cylinder controls the distance between the C-shaft bearing and the side support roller and the lower wire feeding roller 4. The side support roller better guides the coil into the wire support roller 7 and the elastic pressing structure 8.

[0020] The elastic wire pressing structure 8 includes a swing arm 801 hinged to one side of the outer wall of the plate 3, an upper wire pressing roller 802 rotatably mounted on one side of the outer wall of the swing arm 801, and a tension spring 803 hanging on one side of the outer wall of the plate 3. One end of the tension spring 803 is connected to one side of the outer wall of the swing arm 801. During the coil winding process, the tension of the tension spring 803 will force the swing arm 801 and the upper wire pressing roller 802 to swing down continuously, so that the upper wire pressing roller 802 will always press the wire on the wire support roller 7 to reduce the jumping during coil winding.

[0021] The self-tightening wire clamp 10 includes a U-shaped clamp 1001 that is installed through the inside of the winding roller 9 and an I-beam bushing 1004 fixed to one end of the surface of the winding roller 9. The U-shaped clamp 1001 is made of stainless steel. One end of the U-shaped clamp 1001 extends to the outside of the winding roller 9 and is detachably mounted with a baffle 1002. A helical spring 1003 is fitted on the outer circumference of the U-shaped clamp 1001 between the baffle 1002 and the I-beam bushing 1004. When the wire end is fixed in the recess 901, the operator manually pulls the U-shaped clamp 1001, causing the U-shaped clamp 1001 to pass through the baffle 1002. 002 forces the helical spring 1003 to deform, causing the U-shaped clamp 1001 to be pushed out of the recess 901. Then, one end of the U-shaped clamp 1001 is pulled, causing it to deform and move out of the recess 901. When the wire end is in the recess 901, the worker releases the U-shaped clamp 1001, uses it to press the wire end into the recess 901, and releases the bent part of the U-shaped clamp 1001. At this time, the helical spring 1003 elastically resets, causing the U-shaped clamp 1001 to return to its initial position, and the wire end is pressed into the recess 901.

[0022] The baffle 1002 and the U-shaped clamp 1001 are screwed together at one end. When the operator needs to remove the U-shaped clamp 1001, the baffle 1002 is unscrewed from the U-shaped clamp 1001, and the coil spring 1003 is separated from the U-shaped clamp 1001. Finally, the U-shaped clamp 1001 is pulled out from the recess 901.

[0023] In this embodiment, the operator first secures the large-sized coil drum to the unwinding roller 2 to ensure the coil is stable and prevent it from slipping or falling off during operation. The coil end is then led out from the large-sized drum and passes sequentially through the lower guide roller 4, the wire support roller 7, and the elastic wire pressing structure 8 to guide the wire end smoothly and neatly to the next stage, preventing knots, twists, or uneven winding. During operation, the operator must ensure that the wire end flows naturally and smoothly along the predetermined path. When passing through the elastic wire pressing structure, the spring pressure should be adjusted appropriately to ensure that the wire end is pressed tightly without damaging the wire. After the wire end reaches the winding roller 9, a portion of the wire end is gathered up and inserted into the recess 901. Subsequently, the operator uses the self-tightening wire clamp 10 to tighten the wire. The wire end is clamped in the recessed part 901 to ensure that it does not slip or loosen during the subsequent winding process. After clamping the wire, the operator starts the equipment through the control panel 12 and sets the required winding parameters, including the target coil size and winding speed. After the equipment is started, the rotational power of the stepper motor 6 is transmitted to the unwinding roller 2, the lower wire guide roller 4, and the winding roller 9 through the belt drive structure 11. At this time, the wire is wound layer by layer on the winding roller 9. The operator should closely observe the layering of the coil to ensure that the coil is uniform and tight, and avoid gaps or uneven stacking. When the coil reaches the preset size or number of layers, the operator pauses the equipment to stop the stepper motor 6 and cuts, tightens and packages the coil. Finally, the coil is removed from the winding roller 9.
