Description
Technical Field
[0001] This utility model relates to the field of yarn winding technology, specifically to an automatic winding machine yarn tension adjustment device. Background Technology
[0002] Winding machines are specialized equipment in the textile industry. As the final process in spinning and the first process in weaving, winding plays a crucial role in connecting the two processes. It can connect small-capacity bobbins or skeins into large-capacity bobbins, with one bobbin having the capacity equivalent to more than twenty bobbins. The bobbins can be used for multiple processes such as warping, twisting, and weft winding.
[0003] A winding machine is a high-level, latest-generation textile machinery product integrating mechanics, electronics, instrumentation, and pneumatics. It winds bobbins into knotless cones and removes yarn defects during the winding process. Winding refers to the process of rewinding bobbins, skeins, etc., into various forms of cones. Therefore, applying appropriate tension to the yarn during winding ensures good cone formation, facilitates unwinding, and removes various defects from the yarn. Therefore, an automatic winding tension adjustment device is designed to achieve automatic adjustment of the winding tension. Utility Model Content

[0006] The guiding assembly includes a bearing housing, and a guide rod is mounted on the inner side of the bearing housing. The height of the guide rod is not adjustable and it is used to guide the winding yarn.
[0007] The first adjusting assembly includes a U-shaped frame, with a first electric push rod fixed inside the U-shaped frame. A roller frame is fixed to the output end of the first electric push rod, and a first adjusting roller is installed inside the roller frame. The first electric push rod pushes the roller frame to move up and down, and the first adjusting roller is used to press or release the winding yarn downwards.
[0008] The second adjusting assembly includes an adjusting frame, a second adjusting roller mounted inside the adjusting frame, a hinge groove at the end of the adjusting frame, a second electric push rod below the adjusting frame, and a sliding groove on the lower surface of the adjusting frame. A slider is slidably connected within the sliding groove, and the output end of the second electric push rod is hinged to the slider. After passing through the first adjusting assembly, the yarn passes over the second adjusting roller of the second adjusting assembly and finally connects to the winding roller. The second electric push rod is used to push the adjusting frame upwards or downwards, causing the adjusting frame to drive the second adjusting roller to push the yarn upwards or release it.
[0009] The basic tension is applied by pressing down the first adjusting roller, which is the static component; the tension fluctuation is offset in real time by raising and lowering the hinged second adjusting roller, which is the dynamic component.
[0010] The first electric actuator presets an initial pressure based on the yarn type, such as cotton or synthetic fiber, to ensure a stable yarn path. Position closed-loop control is employed, with an encoder providing feedback on the actuator displacement to ensure precise pressure application.
[0011] The second electric actuator performs PID control based on tension sensor signals, such as detecting yarn vibration frequency or direct tension value. Utilizing the mechanical freedom of the T-shaped chute, it allows the second adjusting roller to make oblique fine adjustments to adapt to instantaneous yarn offset.
[0012] As a preferred embodiment of this utility model, a support frame is fixed to the side of the base, and the bearing seat, U-shaped frame, and second electric push rod are fixedly connected to the support frame. The roller frame is hinged to the support frame through a hinge groove.
[0013] As a preferred embodiment of this invention, a positioning rod is fixed above the roller frame, and the positioning rod passes through the U-shaped frame. The positioning rod is used to improve the stability of the roller frame's lifting and lowering.
[0014] As a preferred embodiment of this utility model, a positioning block is fixed to the top of the positioning rod. The positioning block serves to restrict the positioning rod and prevent it from detaching from the U-shaped frame.
[0015] As a preferred embodiment of this utility model, the guide roller, the first adjusting roller and the second adjusting roller are all provided with guide grooves on their surfaces. The guide grooves serve to restrict the winding of yarn, limit yarn deviation, and prevent yarn slippage or tangling.
[0016] As a preferred embodiment of this utility model, the slide groove is a T-shaped groove, and the slider adopts a T-shaped block that cooperates with the slide groove. By using a T-shaped slide groove and slider, the slider is mainly prevented from detaching from the slide groove.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an automatic winding machine yarn tension adjustment device, including a base 1 and a guide component 2, a first adjustment component 3 and a second adjustment component 4 disposed above the base 1, wherein the first adjustment component 3 is located between the guide component 2 and the second adjustment component 4.
[0028] The guiding assembly 2 includes a bearing housing 201, and a guide roller 202 is mounted on the inner side of the bearing housing 201. The height of the guide roller 202 is not adjustable and it is used to guide the winding yarn.
[0029] The first adjusting assembly 3 includes a U-shaped frame 301, a first electric push rod 302 fixed inside the U-shaped frame 301, a roller frame 303 fixed at the output end of the first electric push rod 302, and a first adjusting roller 304 installed inside the roller frame 303. The first electric push rod 302 pushes the roller frame 303 to move up and down, and the first adjusting roller 402 presses the winding yarn downward.
[0030] The second adjusting assembly 4 includes an adjusting frame 401, a second adjusting roller 402 mounted inside the adjusting frame 401, a hinge groove 4011 at the end of the adjusting frame 401, a second electric push rod 404 below the adjusting frame 401, a sliding groove 4012 on the lower surface of the adjusting frame 401, a slider 403 slidably connected in the sliding groove 4012, and the output end of the second electric push rod 404 hinged to the slider 403. After the yarn passes through the first adjusting assembly 3, it passes over the second adjusting roller 402 of the second adjusting assembly 4, and finally connects to the winding roller. The second electric push rod 404 is used to push the adjusting frame 401 upward or pull it downward, causing the adjusting frame 401 to drive the second adjusting roller 402 to push the yarn upward or release it.
[0031] The basic tension is applied by pressing down the first adjusting roller 304, which is the static component; the tension fluctuation is offset in real time by raising and lowering the hinged second adjusting roller, which is the dynamic component.
[0032] The first electric actuator 302 presets an initial pressure based on the yarn type, such as cotton or synthetic fiber, to ensure a stable yarn path. It employs closed-loop position control, with an encoder providing feedback on the actuator displacement to ensure precise pressure application.
[0033] The second electric push rod 404 performs PID adjustment based on tension sensor signals, such as detecting yarn vibration frequency or direct tension value. Utilizing the mechanical degrees of freedom of the T-shaped chute 4012, it allows the second adjusting roller to make oblique fine adjustments to adapt to instantaneous yarn offset.
[0034] Furthermore, a support frame 101 is fixed to the side of the base 1, and the bearing seat 201, the U-shaped frame 301, and the second electric push rod 404 are fixedly connected to the support frame 101. The roller frame 303 is hinged to the support frame 101 through the hinge groove 4011.
[0035] Furthermore, a positioning rod 305 is fixed above the roller frame 303, and the positioning rod 305 passes through the U-shaped frame 301. The positioning rod 305 is provided to improve the stability of the roller frame 303 during lifting.
[0036] Furthermore, a positioning block is fixed to the top of the positioning rod 305. The positioning block serves to restrict the positioning rod 305 and prevent the positioning rod 305 from detaching from the U-shaped frame 301.
[0037] Furthermore, the guide roller 202, the first adjusting roller 304 and the second adjusting roller 402 are all provided with guide grooves. The guide grooves are provided to restrict the winding of yarn, limit the yarn deviation, and prevent yarn slippage or tangling.
[0038] Furthermore, the slide groove 4012 is a T-shaped groove, and the slider 403 adopts a T-shaped block that cooperates with the slide groove 4012. By adopting the T-shaped slide groove 4012 and the slider 403, the slider 403 is mainly prevented from disengaging from the slide groove 4012.
[0039] In summary, this device works by passing the winding yarn over the guide roller 202 of the guide assembly 2, then under the first adjusting roller 304 of the first adjusting assembly 3, then over the second adjusting roller 402 of the second adjusting assembly 4, and finally connecting the winding yarn to the take-up roller. During use, when tension adjustment is required, the first electric push rod 302 and the second electric push rod 404 can be activated. The first electric push rod 302 pushes the roller frame 303 up and down, causing the roller frame 303 to move the first adjusting roller 304. This causes the second electric push rod 404 to move the slider 403 up and down, allowing the slider 403 to slide within the groove 4012. Simultaneously, the slider 403 moves the adjusting frame 401, which in turn moves the second adjusting roller 402, thereby adjusting the tension of the winding yarn.
[0040] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
