Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to an automatic tension-releasing device for a semi-automatic winding machine. Background Art

[0002] Coils are an important part of household appliances, and winding machines are the main equipment for winding enameled wire into coils. Currently, winding machines on the market are divided into semi-automatic winding machines and automatic winding machines. Due to the higher cost and slightly poorer stability of automatic winding, semi-automatic winding machines are still the most widely used winding machines in China.

[0003] After checking the publication number: CN218988450U, a wire tension adjustment device for a winding machine is disclosed. This technology discloses "a wire tension adjustment device for a winding machine, including a transmission mechanism, a tension mechanism and a housing mechanism, the tension mechanism is movably connected to the left side of the housing mechanism, the transmission mechanism is fixedly connected to the top of the tension mechanism, the transmission wheel is rotatably connected to the upper end of the transmission mechanism, the fixed rod is slidably connected to the inside of the tension rod, the spring is fixedly connected to the inner wall of the tension rod, the pressure sensor is fixedly connected to the bottom of the spring, the tension rod is fixedly connected to the top of the tension mechanism, and the fixed wheel is rotatably connected to the left side of the housing mechanism" and other technical solutions, which have "the wire is transmitted within the angle between the transmission wheel and the fixed wheel to prevent deviation and falling off. If the wire is accidentally broken, the wire will not contact the components, preventing mixed hinges from damaging the equipment. The internal pressure sensor cooperates with the electric motor to accurately control the released pressure, thereby controlling the tension and preventing the wire from breaking due to excessive tension, saving costs and improving work efficiency" and other technical effects;

[0004] The above scheme changes the tension of the enameled wire by controlling the conductive wheel (tension wheel). Since the winding machine also needs a fixed wheel (conductor wheel) to guide the enameled wire during the winding process, when the wire diameter of the enameled wire changes during the winding process, the position of the conductor wheel needs to be adjusted to adapt to the new wire diameter; however, in actual operation, since the conductor wheel is usually fixed to the winding machine by bolts and nuts, once the installation position of the conductor wheel is close to the wall or other equipment, the bolts and nuts are difficult to remove smoothly from the back, which undoubtedly brings a lot of inconvenience to the adjustment work. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an automatic tension-removing device for a semi-automatic winding machine, which has the characteristics of convenient and quick disassembly and assembly of the guide wheel and replacement of the installation position, and can automatically remove the tension, thereby reducing the labor intensity of winding, improving work efficiency, and providing reliable winding tension. The stroke of the tension cylinder is adjustable, which can meet the requirements of the wire end length of coils of different specifications and ensure the consistency of the wire end length.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic tension relief device for a semi-automatic winding machine, comprising a machine body, a wire feeding mechanism provided on the machine body and used for feeding and guiding the enameled wire during winding, the wire feeding mechanism comprising:

[0025] A tension assembly 21 is provided on the machine body 1 and is used to adjust the tension of the enameled wire during winding, and a plurality of guide wheels 22 are installed on the tension assembly 21;

[0026] The mounting assembly 23 includes a fixing rod 231 installed on the tension assembly 21 and used to fix the guide wheel 22, a guide rod 232 slidingly installed inside the fixing rod 231, a retaining ring 233 fixed to the outer wall of the middle part of the guide rod 232, a spring 234 sleeved on the guide rod 232, a guide block 235 fixed to the inner end of the guide rod 232, four circumferentially distributed cavities 236 opened on the outer wall of the fixing rod 231, a clamping head 237 hinged inside the cavity 236, a protrusion 238 fixed to the inner wall of the inner end of the clamping head 237, and the protrusion 238 is located inside the outer wall of the guide block 235, and a nut 239 threadedly mounted on the fixing rod 231.

[0027] In this embodiment, when the guide wheel 22 needs to be installed, the installation assembly 23 is passed through the guide wheel 22 and inserted into the installation hole 218 on the installation plate 211, and then the rebound pressure of the spring 234 pushes the retaining ring 233 to cooperate with the guide rod 232 to drive the guide block 235. The guide block 235 drives the clamping head 237 to open outward through the protrusion 238, so that the outer end of the clamping head 237 is in contact with the installation plate 211, and the nut 239 is rotated and tightened to fix the guide wheel 22, so that the guide wheel 22 can be disassembled and replaced as well as the installation position can be changed conveniently and quickly.

[0028] Specifically, the mounting assembly 23 further includes a handle 2310 fixed to the end of the fixing rod 231 , and the outer end of the guide rod 232 extends to the outside of the fixing rod 231 .

[0029] In this embodiment, when the installation position of the guide wheel 22 is changed, the nut 239 is unscrewed by rotating it counterclockwise, and the guide wheel 22 is disassembled and removed, and then the guide rod 232 is pressed to drive the guide block 235. The guide block 235 drives the clamping head 237 to retract into the cavity 236 through the protrusion 238, so that the installation component 23 can be taken out from the front of the installation plate 211; then the guide wheel 22 is installed on the installation hole 218 at other required positions through the installation component 23.

[0032] Specifically, the tension assembly 21 further includes limiting wheels 216 rotatably mounted on both the tension frame 213 and the positioning frame 214 , wherein the limiting wheel 216 on the tension frame 213 is located at the bottom, and the limiting wheel 216 on the positioning frame 214 is located at the top.

Then, the guide rod 232 is pressed to drive the guide block 235. The guide block 235 drives the clamping head 237 to retract into the cavity 236 through the protrusion 238, so that the installation assembly 23 can be taken out from the front of the installation plate 211.

[0038] Then, when installing the guide wheel 22, first pass the installation assembly 23 through the guide wheel 22 and insert it into the installation hole 218 on the installation plate 211. Then, the rebound pressure of the spring 234 pushes the retaining ring 233 to cooperate with the guide rod 232 to drive the guide block 235. The guide block 235 drives the clamping head 237 to open outward through the protrusion 238, so that the outer end of the clamping head 237 fits with the installation plate 211. Then, the nut 239 is rotated and tightened to fix the guide wheel 22 on the installation hole 218 of the installation plate 211.
