Description

Technical Field

[0001] The utility model belongs to the technical field of earphone wire processing, and particularly relates to a tensioning device for earphone wire processing. Background Art

[0002] Earphone wires are important components connecting earphones and audio playback devices. They are usually composed of metal wires wrapped in insulating materials and play the role of transmitting audio signals. One end of the earphone wire is connected to the earphone body, and the other end is provided with a plug for inserting into the jack of the audio playback device. The material and quality of the earphone wire have a certain impact on the audio transmission effect. High-quality earphone wires can reduce signal loss and interference and provide clearer and more stable audio output. At the same time, the length and flexibility of the earphone wire also affect the use experience. An appropriate length allows users to move more freely when using earphones, and a wire with good flexibility is not easily broken or damaged. With the continuous development of electronic devices, earphones have become an indispensable audio device in people's daily lives. As an important part connecting earphones and audio playback devices, the quality and processing technology of earphone wires directly affect the use performance of earphones;

[0003] Chinese Patent with the publication number of "CN220664465U" discloses a headphone wire processing device, which includes a motor and a wire winding shaft. The inner side wall of the wire winding shaft is provided with a reciprocating thread groove. A connecting column is rotatably connected to the inner side wall of the wire winding shaft. A limiting block is fixedly connected to the outer side wall of the connecting column, and the limiting block is in threaded connection with the reciprocating thread groove. One end of the connecting column is fixedly connected with a mounting plate, and the output end of the motor is fixedly connected with a limiting cylinder. In the utility model, the motor drives the limiting cylinder to rotate, the limiting column drives the wire winding shaft to rotate outside the connecting column, and the wire winding shaft continuously reciprocates and slides on the outer side wall of the connecting column, so that the wire winding shaft rotates to completely wind the wire body while reciprocating to continuously adjust the winding position, and the wire body is evenly wound on the outer side of the wire winding shaft, improving the amount of the wire body wound by the wire winding shaft;

[0004] During the use of the above device, although it can assist in rapid production and processing, there is a major defect in the winding of the earphone wire during the processing of the earphone wire, that is, the lack of an effective tensioning structure. First of all, the earphone wire without a tensioning structure is prone to looseness and uneven winding during the winding process. This not only makes the wound wire occupy a large space, which is not convenient for storage and transportation, but also in the subsequent use process, the loose wire is prone to re-winding, bringing great inconvenience to users. Secondly, due to the lack of tension, local accumulation may occur when the earphone wire is wound, which will cause some parts of the wire to bear excessive pressure, and it is easy to cause damage to the internal conductors of the wire in the long run. Moreover, on the processing production line of the earphone wire, the lack of a tensioning structure makes it difficult to control the winding speed. Unstable winding speed may cause stretching or relaxation of the wire, affecting the consistency and quality stability of the product. In addition, the earphone wire without a tensioning structure is prone to loose deformation during handling or slight vibration after winding, reducing the overall aesthetics and quality of the product.

[0025] The tensioning mechanism 6 includes a mounting base 61 which is fixedly installed in the middle of the top of the top base 4. A tensioning assembly 62 is rotatably connected inside the mounting base 61. One end of the tensioning assembly 62 passes through the mounting base 61 and is fixedly installed with a crank 63.

The tensioning assembly 62 can be adjusted through the crank 63, which is convenient to operate. During the wire processing, the tension of the wire can be adjusted according to actual needs to ensure that the wire is in a taut state, improving the stability and compactness of wire winding.

[0026] Reference Figures 1 - 4 , The tensioning assembly 62 includes a turntable 621. A connecting frame 622 is fixedly installed inside the turntable 621.

[0028] Reference Figures 1 - 2 , the guiding mechanism 5 includes a concave seat 51. The concave seat 51 is fixedly installed on the top of the top seat 4 and is located between the inner sides of the mounting seat 61 and the winding mechanism 3. An electric push rod 52 is fixedly installed at the upper end of one side of the concave seat 51. The output end of the electric push rod 52 penetrates through the concave seat 51 and is fixedly installed with a guiding ring 53. The winding mechanism 3 includes a fixed seat 31. The fixed seat 31 is fixedly installed at the rear side of the top of the top seat 4. A driving motor 32 is fixedly connected to one side of the fixed seat 31. The output end of the driving motor 32 penetrates through the fixed seat 31. The output end of the driving motor 32 penetrating through the fixed seat 31 is installed with a winding roller 33 through bolts. The concave seat 51 in the guiding mechanism 5 is fixed on the top seat 4, providing stable support for the electric push rod 52 and the guiding ring 53. The electric push rod 52 can push the guiding ring 53 to slide reciprocally. During the wire winding process, it assists in guiding the wire to move left and right reciprocally, prompting the wire to be evenly wound around the outer surface of the winding roller 33, improving the uniformity and quality of winding. The fixed seat 31 of the winding mechanism 3 provides an installation position for the driving motor 32. The winding roller 33 at the output end of the driving motor 32 can rotate under the drive of the motor to wind the wire. This design makes the wire winding more efficient and neater, improves the practicability and convenience of the entire device, and brings great convenience to the processing of earphone wires.

[0029] Principle of use and advantages: By setting up the rewinding mechanism 3 and the guiding mechanism 5, the device demonstrates excellent performance during actual use. First, the processing equipment can be installed inside the set installation groove 7. During installation, the equipment can be firmly installed using the mounting holes 9 on the mounting parts 8 and bolts. After the processing equipment is installed, the processed wire is passed through the tensioning mechanism 6 in sequence and then inserted into the inside of the guiding ring 53. Subsequently, the outer end of the wire is wound around the outer surface of the rewinding roller 33. At this time, the driving motor 32 is started to operate. The driving motor 32 can drive the rewinding roller 33 to rotate, thereby performing the rewinding operation on the wire. During the rewinding process of the wire, the electric push rod 52 can be started to operate. The electric push rod 52 pushes the guiding ring 53 to slide reciprocally, thereby assisting in driving the guiding ring 53 to guide the wire to move left and right reciprocally. In this way, it can be ensured that the wire is evenly wound around the outer surface of the rewinding roller 33, greatly improving the uniformity of the overall wire rewinding of the device, and further improving the overall convenience of use of the device. It is very worthy of popularization and application;

[0030] By setting up the tensioning mechanism 6, the device exerts powerful functions during use. The wire can be passed through the inside of the connecting frame 622. At this time, the wire is located between the inside of the two tensioning rollers 625. After the wire passes through the tensioning rollers 625, the turntable 621 can be driven to rotate by pulling the crank 63. At this time, when the turntable 621 rotates, it can drive the connecting frame 622 to rotate. When the connecting frame 622 rotates, it can drive the two rotating shafts 623 to rotate. When the upper rotating shaft 623 rotates, it will move downward, and when the lower rotating shaft 623 rotates, it will move upward. The tensioning rollers 625 on the outer sides of the two rotating shafts 623 will change the extrusion degree of the rotating shafts 623 on the wire according to the rotation degree of the crank 63. During use, only by adjusting the rotation angle of the crank 63 can the tensioning rollers 625 further extrude the wire, making the wire in a taut state. During the tensioning process, the outer sides of the tensioning rollers 625 come into contact with and extrude the wire, and the tensioning springs 624 expand and contract to provide elastic tension at all times, prompting the tensioning rollers 625 to assist in extruding the wire, keeping the wire in a taut state at all times, and at the same time can also assist in buffering. Moreover, the tensioning springs 624 are arranged at equal intervals on the outer surface of the rotating shaft 623. With the traction of the rotation of the rotating shaft 623, each tensioning spring 624 can assist in expanding and contracting and tensioning. The elastic forces of each tensioning spring 624 can act on the wire. It can be seen that the device can have good tensioning and buffering performance during use, making the wire rewinding more stable and compact. And after the adjustment is completed, only by turning the hand-tightening screw 64 can the hand-tightening screw 64 be inserted into the corresponding position of the limit hole 65. It can be seen that the device can not only achieve a good tensioning effect, but also assist in adjusting the tensioning force, further improving the quality of wire production and processing.
