Description

Technical Field

[0001] This utility model relates to the field of winding tools, and in particular to an electric winding machine. Background Technology

[0002] Manual yarn winders are the primary tool for winding yarn in households, typically consisting of a stand, a winding spool, and a handle. The spool is used to hold and wind the yarn, while the handle rotates it. The operator manually turns the handle to rotate the spool, evenly winding the yarn onto it. Once the desired amount of yarn is wound, the operator can stop turning the handle, completing the winding of the yarn ball. However, using a manual yarn winder requires the operator to constantly turn the handle and adjust the yarn, making the entire winding process tedious and monotonous. This operation is not only physically demanding but also easily leads to fatigue. Furthermore, manual winding is inefficient, failing to meet the increasing demands for winding speed and quality. As the need for efficient and convenient winding tools grows, the limitations of traditional manual yarn winders become increasingly apparent. Therefore, developing a more efficient winding device is particularly important to meet the needs of modern household users. Utility Model Content

One end of the hollow sleeve is connected to the linkage gear, and the other end of the hollow sleeve is connected to the connecting rod. The connecting rod extends into the hollow sleeve and forms an annular cylindrical cavity with the hollow sleeve.

The metal bearing fills the portion of the annular cylindrical cavity near the fixed gear.

[0012] In one possible implementation, the electric winding machine further includes a connector and a wire clamp, one end of the connector being connected to the main body and the other end of the connector being provided with the wire clamp, the wire clamp and the winding drum being disposed opposite to and separately.

[0013] The wire clamp includes a spring and a clamping body; when the spring is in a contracted state, the spring and the clamping body separate to allow the wire to extend between the spring and the clamping body; when the spring is in a reset state, the spring and the clamping body come into contact to clamp the wire.

[0017] In one possible implementation, the first opening and / or the second opening are provided with two symmetrical and separate wedge-shaped edges, the distance between the two wedge-shaped edges near the end of the groove being less than the distance between the two wedge-shaped edges away from the groove.

[0036] Please refer to Figure 1 The diagram shown is a structural schematic of the electric winding machine provided in the first embodiment of this utility model.

[0037] This utility model proposes an electric winding machine, including a main body 10 and a winding drum 20. The main body 10 includes a control circuit, a motor device 11 and a transmission mechanism 12. The control circuit and the motor device 11 are electrically connected. The motor device 11 includes a motor and a motor shaft. One end of the transmission mechanism 12 is connected to the motor shaft, and the other end of the transmission mechanism 12 is connected to the winding drum 20.

[0038] The control circuit can control the motor device 11 to drive the transmission mechanism 12 to move, thereby causing the winding drum 20 to rotate.

[0039] Specifically, the electric winding machine fully considers the shortcomings of traditional manual winding machines, aiming to improve winding efficiency and convenience through electric drive. Traditional manual winding machines are cumbersome and time-consuming to operate, requiring significant manual labor. Therefore, the electric winding machine was developed to save time and effort, freeing up the user's hands. By replacing manual rotation of the handle with a motor drive, the electric winding machine can automatically complete the winding process, not only increasing winding speed but also reducing reliance on operator physical strength. The electric winding machine is fully electrically controlled, meaning that the entire winding process can be completed automatically without user intervention, significantly improving winding efficiency. Furthermore, the electric winding machine can be equipped with an intelligent detection module in the control circuit to monitor the winding status of the wire in a timely manner. Once a situation is detected where the wire cannot move (such as a knot), the electric winding machine can automatically cut off the power and sound an alarm via a buzzer, improving operational safety throughout the winding process and effectively preventing equipment damage. The electric winding machine can also be equipped with a DC power interface in the control circuit. Users only need to connect the power cord to the DC power interface to provide the necessary power to the electric winding machine and ensure the normal operation of the winding action.

[0040] Specifically, the motor is a worm gear motor. A worm gear motor is a type of motor that combines worm gear and worm drive, featuring increased torque and speed reduction, making it suitable for small electric winding machines. Its high torque output effectively overcomes wire tension, ensuring smooth winding; the speed reduction function allows for controllable winding speed, preventing uneven winding or damage caused by excessive speed. Furthermore, the worm gear motor has a compact structure, runs smoothly, and has low vibration and noise, making it suitable for small household appliances and providing a good user experience.

[0041] Compared with existing technologies, the electric winding machine proposed in this embodiment can automatically rotate the winding drum 20 by adjusting the motor device 11 through the control circuit, thereby achieving automated winding operation. Users only need to start the electric winding machine; the winding drum 20 will automatically rotate and complete the winding work without manually turning the handle. This greatly reduces the labor intensity of operators and avoids fatigue caused by manual operation. At the same time, the electric winding machine can reduce the impact of human factors on winding quality, further ensuring stable winding performance. Furthermore, the speed of electric winding is usually much higher than that of manual winding, allowing the electric winding machine to complete more winding tasks in a shorter time, thus significantly improving overall winding efficiency.

[0042] Please refer to Figure 2 As shown, it is a structural disassembly diagram of the electric winding machine provided in the first embodiment of this utility model.

[0043] In some embodiments of this application, the control circuit is provided with a potential knob 13. When the potential knob 13 is rotated, the motor device 11 drives the winding drum 20 to rotate at different speeds through the transmission mechanism 12.

[0044] Specifically, the operator can easily adjust the motor's output speed by rotating the potentiometer knob 13, thereby driving the winding drum 20 to rotate at different winding speeds. This enhances the flexibility and control precision of the electric winding machine, meeting the winding needs of different users. Its intuitive rotation method improves the user experience and reduces the learning curve. Furthermore, the potentiometer knob 13 provides smooth speed changes, effectively preventing malfunctions caused by sudden speed variations.

[0045] Please refer to Figure 3 and Figure 4 As shown, these are schematic diagrams and disassembled diagrams of the transmission mechanism 12 of the electric winding machine provided in this embodiment of the present invention.

[0046] In some embodiments of this application, the winding drum 20 includes a winding rod 21, the transmission mechanism 12 includes a transmission gear 121 and a gear device 122, the gear device 122 includes a linkage gear 1221 and a connecting rod 1222 fixedly connected, one end of the connecting rod 1222 is fixedly connected to the linkage gear 1221, the other end of the connecting rod 1222 is fixedly connected to the winding rod 21, both the connecting rod 1222 and the winding rod 21 are inclined relative to the vertical direction, the shaft of the transmission gear 121 is fixedly connected to the motor shaft, and the transmission gear 121 and the linkage gear 1221 mesh.

[0047] The control circuit can control the motor device 11 so that the motor drives the transmission gear 121 to rotate through the motor shaft. The rotating transmission gear 121 drives the linkage gear 1221 to rotate, so as to drive the winding rod 21 to rotate through the connecting rod 1222.

[0048] Specifically, the winding rod 21, as the core component for winding the wire, is driven by the transmission mechanism 12 to rotate, thereby completing the winding of the wire. Of course, the winding drum 20 may also include other components, such as a disc at the bottom of the winding rod 21 to conceal the winding gear 22, improving the product's aesthetics and ensuring a stable connection with the winding gear 22. It should be noted that, in addition to using two gears (transmission gear 121 and linkage gear 1221) for coordinated movement, the transmission mechanism 12 can also use other numbers and different gear engagement mechanisms, as long as they can effectively drive the winding rod 21 to rotate. In this embodiment, the transmission mechanism 12 only has two gears. This design not only saves space but also improves the portability and ease of use of the device, meeting the needs of modern families for efficient and convenient tools.

[0049] Specifically, both the connecting rod 1222 and the winding rod 21 are inclined relative to the vertical direction. This inclined layout can effectively reduce the overall height and floor space of the electric winding machine, making the product more compact and easier to place and store. In addition, the inclined design can also optimize the winding angle of the wire during the winding process, improving winding efficiency and quality.

[0050] In some embodiments of this application, the winding rod 21 forms an angle of 20 to 50 degrees with the vertical direction.

[0051] Specifically, the wire to be wound is generally introduced horizontally. The winding rod 21 forms an angle of 20 to 50 degrees with the vertical direction, allowing the wire to be wound to be arranged diagonally and interlaced on the winding rod 21, forming a cross-pattern, thereby increasing the stability of the resulting coil. Simultaneously, this angle also creates square gaps on the coil. These square gaps make it easier for users to handle the wound coil, reducing subsequent operational difficulties. Furthermore, the cross-pattern and square gap design increases the aesthetics of the finished coil, enhancing the user experience.

[0052] In some embodiments of this application, the main body 10 further includes a housing 14, the winding drum 20 further includes a winding gear 22, the winding rod 21 is fixedly connected to the axial position of the top surface of the winding gear 22, the connecting rod 1222 is fixedly connected to the axial position of the bottom surface of the winding gear 22, the transmission mechanism 12 further includes a connecting column 123 and a fixed gear 124, the fixed gear 124 is fixedly disposed at the top end of the connecting column 123, the fixed gear 124 extends above the housing 14 and meshes with the winding gear 22; when the connecting rod 1222 drives the winding gear 22 to rotate along the circumferential direction of the fixed gear 124, the winding gear 22 drives the winding rod 21 to rotate.

[0053] Specifically, the addition of a meshing mechanism between the fixed gear 124 and the winding gear 22 enhances structural stability, reduces vibration and misalignment during high-speed operation, and ensures smooth rotation of the winding rod 21. Furthermore, the introduction of the fixed gear 124 and the winding gear 22 helps optimize the power transmission path, improve transmission efficiency, and reduce energy loss. Additionally, the fixed gear 124 can adjust the speed and torque output through gear ratio adjustments, improving the adaptability of the electric winding machine.

[0054] In some embodiments of this application, the transmission mechanism 12 further includes an annular metal bearing 125, and the gear device 122 further includes a hollow sleeve 1223. One end of the hollow sleeve 1223 is connected to the linkage gear 1221, and the other end of the hollow sleeve 1223 is connected to the connecting rod 1222. The connecting rod 123 extends into the hollow sleeve 1223 and forms an annular columnar cavity with the hollow sleeve 1223. The metal bearing 125 is disposed at one end of the annular columnar cavity near the fixed gear 124 and located on the surface of the housing 14. The metal bearing 125 fills the portion of the annular columnar cavity near the fixed gear 124.

[0055] Specifically, the metal bearing 125, employing a miniature bearing, fills the portion of the annular cylindrical cavity near the fixed gear 124, effectively reducing friction and vibration generated during the rotation of the winding gear 22, and decreasing heat generated during transmission, thereby improving transmission efficiency and system stability. Furthermore, the metal bearing 125 also improves the smoothness of rotation, making the rotation of the winding rod 21 smoother, reducing noise, and enhancing the user experience.

[0056] Please refer to Figure 5 and Figure 6 The figures shown are schematic diagrams of the first angle of the electric winding machine provided in the second embodiment of this utility model, and... Figure 5 A schematic diagram of the structure of part A in the middle.

[0057] In some embodiments of this application, the electric winding machine further includes a connector 30 and a wire clamp 40. One end of the connector 30 is connected to the main body 10, and the other end of the connector 30 is provided with the wire clamp 40. The wire clamp 40 and the winding drum 20 are disposed opposite to each other and separately.

[0058] The wire clamp 40 includes a spring and a clamping body; when the spring is in a contracted state, the spring and the clamping body separate to allow the wire to extend between the spring and the clamping body; when the spring is in a reset state, the spring and the clamping body come into contact to clamp the wire.

[0059] Specifically, the introduction of connector 30 makes the connection between the main body 10 of the electric winding machine and the wire clamp 40 more flexible, facilitating installation and disassembly, thereby improving the maintainability and convenience of the equipment. Connector 30 and the main body 10 can be fixed together by screws 415, a simple and easy-to-implement fixing method. Connector 30 can be a section of L-shaped metal strip. The distance between the wire clamp 40 and the winding drum 20 is determined by the horizontal length of the metal strip and the maximum radial width of the wire coil (the radial width of the finished winding product). When the finished winding product is on the winding rod 21, it needs to meet the condition that the wire coil and the wire clamp 40 do not interfere with each other. The wire clamp 40 effectively fixes and holds the wire, ensuring that the wire will not loosen or slip during winding, thereby improving the accuracy and stability of winding. The spring in the wire clamp 40 provides an automatic clamping function; when the spring is in the reset state, it can easily clamp the wire, ensuring that the wire remains taut during winding and avoiding uneven winding or knotting caused by wire slack. In addition, the retracted state of the spring allows the wire to freely extend into the clamp, making it convenient for users to change the wire.

[0060] Please refer to Figure 7 and Figure 8 As shown, these are structural schematic diagrams of the electric winding machine provided in the second embodiment of this utility model at the second angle, and... Figure 7 A schematic diagram of the structure of part B in the middle.

[0061] In some embodiments of this application, the spring is a tower spring 42, with a base 421 provided at the end of the tower spring 42 with a larger radial width, and a hand-tightening screw 422 provided at the end of the tower spring 42 with a smaller radial width. When the spring is in the reset state, the base 421 closes the surface of the clamping body that is in contact with the tower spring 42.

[0062] Specifically, the tower spring 42 is a spring with a special shape, characterized by a larger radial width at one end and a smaller radial width at the other. This structure gives the tower spring 42 a unique advantage when clamping and releasing wires. The larger clamping end (corresponding to the base 421) provides a larger contact surface, ensuring even pressure distribution when clamping the wire, thus effectively preventing slippage or damage. The smaller handheld end (corresponding to the thumbscrew 422) is convenient for the user to grip and operate.

[0063] Specifically, the base 421 can tightly seal the surfaces where the clamping body and the tower spring 42 fit together, ensuring that there is no gap between the clamping body and the tower spring 42 when the tower spring 42 is in the reset state. This enhances the stability of clamping the wire and effectively prevents the wire from coming out. The presence of the hand-tightening screw 422 provides convenience for users. By pulling the hand-tightening screw 422, users can easily pull the tower spring 42 to adjust the clamping force, facilitating wire winding and removal operations.

[0064] Please refer to Figure 9 and Figure 10 The figures shown are schematic diagrams of the first and second angles of the extension part 411 and the clamping part 412 of the electric winding machine provided in this embodiment of the present invention.

[0065] In some embodiments of this application, the top of the winding drum 20 is provided with a groove 23 for holding the wire end, the clamping body includes an extension part 411, a clamping part 412 and an extension part 413, the extension part 411 is provided with a first through hole 4111 having a first opening, the clamping part 412 is provided with a U-shaped opening 4121, the opening of the U-shaped opening 4121 faces the spring, the extension part 413 is provided with a second through hole 4131 having a second opening, and an angle of 85-95 degrees is formed between the plane where the first through hole 4111 is located and the plane where the second through hole 4131 is located;

[0066] After passing through the first opening, the wire enters the first through hole 4111, then passes through the U-shaped opening 4121 and enters the clamping part 412, then passes through the second opening and enters the second through hole 4131, and finally reaches the winding drum 20 and is inserted into the groove 23.

[0067] Specifically, a groove 23 is provided on the top of the winding drum 20 (i.e., the groove 23 is located on the top of the winding rod 21) to hold the wire end in place, ensuring that the wire is firmly fixed during the winding process and preventing loosening or slippage. Furthermore, after the electric winding machine completes the winding of the coil, the groove 23 can also quickly position the wire end. The clamping body consists of an extension part 411, a clamping part 412, and a lead-out part 413, which together form a reasonable wire guiding path. The first through hole 4111 of the extension part 411 and the second through hole 4131 of the lead-out part 413 have a first opening and a second opening, respectively, facilitating smooth wire passage. An angle of 85-95 degrees is formed between the two, effectively guiding the wire smoothly through the U-shaped opening 4121 of the clamping part 412, maintaining the stability of the wire movement. The U-shaped opening 4121 of the clamping part 412 faces the spring (tower spring 42) and is used to limit the wire and automatically clamp the wire under the action of the spring, ensuring that the wire is kept taut while moving smoothly. It should be noted that the extending part 411 and the clamping part 412 are integrally formed to reduce the number of parts, reduce potential failure points, and thus improve the reliability of the equipment.

[0068] In some embodiments of this application, the first opening and / or the second opening are provided with two symmetrical and separate wedge-shaped edges 414, and the distance between the two wedge-shaped edges 414 near the end of the groove 23 is less than the distance between the two wedge-shaped edges 414 away from the groove 23.

[0069] Specifically, the gradually widening wedge edge 414 allows the wire to slide smoothly into the opening where the wedge edge 414 is located, reducing friction and resistance. Simultaneously, the smaller spacing at the end near the groove 23 effectively restricts the reverse movement of the wire, creating a locking effect and ensuring the wire does not easily slip out of the opening, thereby improving winding efficiency. Furthermore, the wedge edge 414 design makes wire insertion simple and intuitive for users, effectively guiding them to correctly replace or remove the wire and reducing the possibility of misoperation.

[0070] Specifically, the bottom of the housing 14 of the electric winding machine can also be provided with a mounting position for a fixing clip. After the fixing clip is installed in the mounting position and locked with the table, the electric winding machine can be stably fixed on the table, thereby reducing the possibility of displacement of the electric winding machine during the winding process and further enhancing the stability of the winding process.

[0071] The electric winding machine provided in this embodiment features simple structure, automated operation, reliability and durability, and can meet the winding needs of various wires, providing an efficient and reliable winding solution for home DIY (Do It Yourself) projects.

[0072] It should be noted that the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
