[0002] As a core conductive component in electrical equipment such as motors, transformers, and inductors, electromagnetic wire requires its surface to be wrapped with insulating materials (such as insulating paper or mica tape) using a wrapping machine to meet electrical insulation performance requirements. With the development of electrical equipment towards higher power and miniaturization, higher standards have been placed on the precision, efficiency, and consistency of electromagnetic wire wrapping. Four-piece wrapping machines, capable of simultaneously wrapping multiple wires, effectively improve production efficiency and have become one of the mainstream equipment for manufacturing mid-to-high-end electromagnetic wire.
[0003] The wire pressing mechanism is a key component of the four winding machines. Its core function is to apply stable and adjustable pressure to the electromagnetic wire during the winding process, ensuring that the wire remains taut and is conveyed along a preset path. Existing electromagnetic wire pressing mechanisms often have a fixed pressure during use, requiring the replacement of adapter components for electromagnetic wires of different diameters and materials. This results in poor versatility, time-consuming replacement processes, reduced production efficiency, and inconvenience. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example
[0026] like Figure 1 , Figure 2 and Figure 3 As shown in one embodiment of this utility model, a wire pressing mechanism for a four-group electromagnetic wire wrapping machine includes a pressing assembly 1 and a frame 2. The pressing assembly 1 includes a placement roller 101, a heating roller 103, and a pressure roller 104 arranged along the electromagnetic wire conveying direction. The heating roller 103 and the pressure roller 104 are mounted on the placement roller 101 by fasteners 102. The placement roller 101 is rotatably connected to a rotating shaft 202 at one end of the placement frame 201. The pressure roller 104 is fitted onto the heating roller 103 and fits tightly. The pressure roller 104 is provided with a wire groove 1041 that matches the electromagnetic wire.
[0027] When the pressure roller 104 of the pressing component 1 presses the electromagnetic wire, it applies appropriate pressure to the electromagnetic wire, thereby making it tightly press against the electromagnetic wire. The number of pressing components 1 and their relative positions are set according to actual usage requirements, so as to ensure that all the pressure rollers 104 can cooperate with each other to press the electromagnetic wire in all directions.
[0028] The first baffle 1011 integrally formed on the mounting roller 101 abuts against one end of the heating roller 103 and the pressure roller 104.
[0029] The fastener 102 is threadedly connected to the threaded section on the mounting roller 101, and a second baffle 1021 is integrally formed at the part that abuts against the heating roller 103 and the pressure roller 104.
[0030] The first baffle 1011 and the second baffle 1021 cooperate with each other to form a limiting and clamping mechanism for the heating roller 103 and the pressure roller 104 on the mounting roller 101, which enhances the installation stability of the mounting roller. When the electromagnetic wire does not match the pressure roller 104, the fastener 102 can be removed from the mounting roller 101, and then the pressure roller 104 can be removed from the heating roller 103. Then, the matching pressure roller 104 can be replaced, which improves the convenience of use.
[0031] Among them, an electric heater 1031 is fixedly embedded on the electric heating roller 103. Several heat-conducting fins 1032 are evenly distributed along the axial direction on the outer periphery of the electric heater 1031. The electric heater 1031 is electrically connected to an external electric control system and is used to heat the pressure roller 104. The heating temperature can be adjusted by the electric control system to adapt to the softening temperature of different insulating materials.
[0032] Among them, the groove 1041 on the outer periphery of the pressure roller 104 is adapted to the electromagnetic wire and is set to feed the wire along the electromagnetic wire, so that the pressure roller 104 can stably contact the electromagnetic wire and complete the pressing of the electromagnetic wire. The pressure roller 104 is also provided with heat-conducting grooves 1042 that correspond one-to-one with the heat-conducting fins 1032. The heat-conducting fins 1032 are embedded in the heat-conducting grooves 1042 to enhance the heat transfer efficiency and realize the heat transfer between the electric heating roller and the pressure roller.
[0033] The frame 2 includes a mounting frame 201 for cooperating with the pressing assembly 1. One end of the mounting frame 201 is slidably connected to the support rod 203 and abuts against one end of the support spring 205. The other end of the support spring 205 abuts against the adjusting nut 207 mounted on the support rod 203. One end of the support rod 203 passes through the mounting frame 201 and is threadedly connected to a fixing nut 204. The other end is fixedly connected to the connecting frame 209 through a connecting rod head 208. The connecting frame 209 is fixedly connected to the frame of the electromagnetic wire winding machine.
[0034] The mounting frame 201 has a through hole at one end connected to the support rod 203 for the rod to slide through. To ensure that the mounting frame 201 slides smoothly and stably on the support rod 203 without causing axial rotation of the support rod 203, a limit key is embedded in the through hole. A groove matching the limit key is opened on the rod of the support rod 203, and the limit key is slidably connected in the groove.
[0035] Among them, the support rod 203 is provided with a threaded section rod body that matches the fixing nut 204 and the adjusting nut 207. The support spring 205 is fitted on the threaded section rod body. The fixing nut 204 can prevent the mounting frame 210 from sliding off the support rod 203 and ensure the stable use of the frame 2.
[0036] A washer 206 is placed between the support spring 205 and the adjusting nut 207. The washer 206 is slidably fitted on the threaded section of the support rod 203, which improves the contact stability between the adjusting nut 207 and the end of the support spring 205. Thus, when the adjusting nut 207 is rotated on the support rod 203, it can be smoothly compressed through the washer 206, thereby adjusting the magnitude of the supporting force applied by the support spring 205 to the mounting frame 201. In the event of a sudden change in stress on the wire during the electromagnetic wire transportation process, the pressing component 1 can slide appropriately on the support rod 203 through the mounting frame 201 to buffer the stress acting on the electromagnetic wire and prevent damage to the electromagnetic wire.
[0037] Among them, the connecting rod head 208 at the end of the support rod 203 is fixedly connected to one end of the connecting frame 209 by connecting bolts. A rubber pad is placed at the contact part between the connecting rod head 208 and the connecting frame 209 to ensure a stable connection between the two, so that the entire frame 2 can be used stably. The pressing component 1 is stably installed on the frame of the wrapping machine. After the electromagnetic wire is wrapped, the wrapped electromagnetic wire body is pressed so that the wrapping material can better adhere to the electromagnetic wire.
[0038] During operation, adjust the pressure of the pressure roller 104 on the electromagnetic wire according to the specifications of the electromagnetic wire, rotate the adjusting nut 207 to compress the support spring 205, and adjust the pressure applied by the support spring 205 to the mounting frame 201 to complete the adjustment of the pressure of the pressure roller 104 on the electromagnetic wire.
[0039] After adjustment, the temperature of the electric heater 1031 is set through the electronic control system. Then the electric heater 1031 is running. The heat generated by the electric heater 1031 is transferred to the pressure roller 104 through the heat-conducting fins 1032 and the heat-conducting grooves 1042. Then the pressure roller 104 transfers the heat to the insulation layer of the wire. The pressure roller 104 applies stable pressure to ensure that the insulation layer is tightly attached to the electromagnetic wire. Finally, it is delivered to the wrapping head of the wrapping machine to complete the wrapping.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
