[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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 protection scope of the present utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses a tension adjustment device for bamboo fiber elastic yarn. A fixed rod 101 is fixedly connected to the front and rear side walls of the inner cavity of the outer shell 100, supporting a swing arm 102. The swing arm 102 is rotatably connected to the outer surface of the fixed rod 101, allowing for tension adjustment of the elastic yarn. A sector gear 103 is fixedly connected to the outer wall of the swing arm 102, facilitating rotation. A threading groove is provided at the other end of the swing arm 102. A slide 104 is evenly fixedly connected to the right side wall of the inner cavity of the outer shell 100, limiting and guiding the movement of the rack 105 to prevent it from shifting. The inner cavity of the outer shell 100 is slidably connected with racks 105, which facilitates the rotation of sector gears 103. The racks 105 mesh with sector gears 103. The left side wall of the inner cavity of the outer shell 100 is uniformly fixedly connected with sleeves 106, which facilitates the support of push springs 107. The left side wall of the inner cavity of the sleeves 106 is uniformly fixedly connected with push springs 107, which facilitates the pushing of push frame 108. The right end of the push springs 107 is uniformly fixedly connected with push frame 108, which facilitates the pushing of racks 105. Push frame 108 is located at the left end of rack 105. The right side wall of the outer shell 100 is uniformly provided with swing grooves, and swing arms 102 are located in the inner cavity of the swing grooves.

[0021] In this embodiment: the conveyed bamboo fiber elastic filaments are passed through the threading groove, and the bamboo fiber elastic filaments pull the swing arm 102. The pull causes the swing arm 102 to rotate, which in turn drives the sector gear 103 to rotate. The sector gear 103 drives the rack 105 to rotate, and the rack 105 pushes the pusher frame 108 to move. The pusher frame 108 compresses the pusher spring 107, and the pusher spring 107 adjusts the opening. When the tension of the bamboo fiber elastic filaments changes, the elastic force of the pusher spring 107 facilitates the rotation of the swing arm 102, thereby facilitating the adjustment of the bamboo fiber elastic filament tension. This allows the device to easily adjust the tension of multiple sets of bamboo fiber elastic filaments, which is beneficial for subsequent secondary processing and avoids breakage or poor uniformity.

[0022] Adjusting blocks 109 are slidably connected to the inner wall of the sleeve 106. The adjusting blocks 109 facilitate the compression and stretching of the push spring 107. Adjusting screws 110 are screwed to the left side wall of the sleeve 106. The adjusting screws 110 facilitate the movement of the adjusting blocks 109. The right end of the adjusting screw 110 is rotatably connected to the left side wall of the adjusting block 109. The push spring 107 is fixedly connected to the right side wall of the adjusting block 109. The left end of the adjusting screw 110 passes through the left side wall of the outer shell 100 and is fixedly connected to a knob. The knob facilitates the rotation of the adjusting screw 110.

[0023] In this embodiment: by rotating the adjusting screw 110, it moves on the sleeve 106. The movement of the adjusting screw 110 drives the adjusting block 109 to move. The adjusting block 109 stretches and compresses the push spring 107, causing the elastic force of the push spring 107 to change. This facilitates the adjustment of the swinging elastic force of the swing arm 102. The device can easily adjust the elastic force of the push spring 107, and facilitate the adjustment of the tension of elastic wires of different thicknesses. It has a strong buffering capacity and can effectively prevent the elastic wires from breaking.

[0024] The front and rear side walls of the inner cavity of the wire feeding groove are rotatably connected with wire feeding wheels 111. The rolling of the wire feeding wheels 111 facilitates the conveying of the elastic wire. The outer wall of the wire feeding wheels 111 is provided with a wire ring groove.

[0025] In this embodiment, the rolling of the lead-out wheel 111 facilitates the guidance of the bamboo fiber elastic yarn, making it easier for the device to roll and transport the bamboo fiber elastic yarn, avoiding wear of the elastic yarn during transportation, and improving the output of the bamboo fiber elastic yarn, thus enhancing the practicality of the device.

[0026] The right side wall of the outer casing 100 is uniformly connected to a guide wheel 112, which facilitates the guiding and conveying of the elastic line. The guide wheels 112 are arranged in an alternating pattern.

[0027] In this embodiment: When the bamboo fiber elastic filaments are fed onto the line, they are sequentially and interlaced and then fed to the outer wall of the guide wheel 112. The guide wheel 112 facilitates the guidance and limiting of the bamboo fiber elastic filaments, which is beneficial for the exit of the elastic filaments and improves the working efficiency of the device.

[0028] The inner wall of the sleeve 106 is square, and the outer walls of the adjusting block 109 and the pusher 108 are matched with the inner wall of the sleeve 106.

[0029] In this embodiment, the inner wall of the sleeve 106 is square to facilitate the limiting and guiding of the movement of the adjusting block 109 and the pushing frame 108, and to prevent the adjusting block 109 and the pushing frame 108 from deflecting, which is beneficial for adjusting the elastic force of the pushing spring.
