[0024] Example 1

[0025] like Figure 1 and Figure 3 As shown, the present invention proposes a tension detection device for a DTY texturing machine, comprising a support frame 1, a detection box 15 at the top of the support frame 1, and a guide groove 2 on the front end face of the support frame 1. A detector 16 is fixedly connected to the inner wall of the detection box 15. The support frame 1 is welded from steel profiles to provide rigid support for the entire device. The guide groove 2 on its front end face is used to cooperate with the power structure to realize the sliding of components and the entry of materials. The detection box 15 at the top of the support frame 1 is a sealed box structure to avoid external interference. A detector 16 is fixedly connected to its inner wall. The detector 16 adopts a high-precision tension sensor, which can collect yarn tension data in real time and feed it back to the control system.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the inner wall of the support frame 1 is provided with a detection and transmission structure. The detection and transmission structure includes a connecting seat 10 slidably connected to the inner wall of the support frame 1. Multiple guide rollers 11 are fixedly connected to both sides of the bottom end of the connecting seat 10. The multiple guide rollers 11 are grouped in pairs, and a gathering wheel 12 is rotatably connected between each group of guide rollers 11. A guide port 13 is fixedly connected to the center position of each group of guide rollers 11 near the top end. A top guide port 14 is fixedly connected to the top end of the guide port 13, and the top end of the guide port 13 passes through the connecting seat 10. Multiple guide detection wheels 17 are fixedly connected to the inner bottom end face of the detection box 15, and the detector 16 is located on one side of the multiple guide detection wheels 17. The connecting seat 10 is slidably connected to the inner wall of the support frame 1. The connecting seat 10 is made of alloy steel plate and serves as the mounting base for the yarn guiding component. Multiple guide rollers 11 are fixedly connected to both sides of the bottom end of the connecting seat 10. The guide rollers 11 are rotating rollers mounted on a bracket, symmetrically distributed in pairs, used to guide the yarn direction and reduce yarn wear. Each group of guide rollers 11 is rotatably connected to a gathering wheel 12. The gathering wheel 12 has an annular groove on its surface, which can neatly gather the scattered yarn and prevent tangling. The center position of each group of guide rollers 11 is fixedly connected to the top of the guide port 13. The guide port 13 is a trumpet-shaped metal part with a large inlet and a small outlet, guiding the yarn accurately into the detection box 15. The top of the guide port 13 is fixedly connected to the top of the top guide port 14, which passes through the connecting seat 10 to further constrain the yarn path. Multiple guide detection wheels 17 are fixedly connected to the inner bottom end face of the detection box 15. The guide detection wheels 17 cooperate with the detector 16. When the yarn passes around the guide detection wheels 17, the detector 16 accurately measures the yarn tension by sensing the force change of the guide detection wheels 17.

[0027] In addition, such as Figure 1 , Figure 2 and Figure 3As shown, a power structure is provided on both sides of the outer wall of the support frame 1. The power structure includes extension blocks 3 fixed to both sides of the outer wall of the support frame 1. A transmission seat 4 is fixedly connected to the top of each of the two extension blocks 3. An air pump 5 is fixedly connected to the top of each of the two transmission seats 4. A pneumatic block 6 is slidably connected to the inner wall of each of the transmission seats 4. A connecting block 7 is fixedly connected to one side of the outer wall of each of the two pneumatic blocks 6. A limit slide rod 9 is fixedly connected to one side of each of the two connecting blocks 7. A sliding groove 8 is provided on both sides of the outer wall of the support frame 1. The two limit slide rods 9 are slidably connected to the inner wall of the sliding groove 8. One end of each limit slide rod 9 is fixedly connected to both sides of the connecting seat 10, and the two limit slide rods 9 correspond to each other. Extension blocks 3 are fixed on both sides of the outer wall of the support frame 1 for installing power components. The top of each of the two extension blocks 3 is fixedly connected to the top of the two extension blocks 1. Each end is fixedly connected to a transmission seat 4, which is a hollow metal seat. An air pump 5 is fixedly connected to the top of the transmission seat 4. The air pump 5 provides compressed air as a power source. A pneumatic block 6 is slidably connected to the inner wall of the transmission seat 4. The pneumatic block 6 slides back and forth along the inner wall of the transmission seat 4 under the drive of the air pump 5. A connecting block 7 is fixedly connected to one side of the outer wall of each of the two pneumatic blocks 6. The connecting block 7 is used to connect the pneumatic block 6 and the limiting slide rod 9. A limiting slide rod 9 is fixedly connected to one side of each of the two connecting blocks 7. Sliding grooves 8 are opened on both sides of the outer wall of the support frame 1. The limiting slide rod 9 is slidably connected to the inner wall of the sliding groove 8. The sliding groove 8 guides and limits the sliding of the limiting slide rod 9. The sliding of the pneumatic block 6 drives the connecting seat 10 to slide along the inner wall of the support frame 1 through the connecting block 7 and the limiting slide rod 9, thereby realizing the adjustment of the detection position.

[0028] In addition, such as Figure 2 As shown, support rods 18 are fixedly connected to both sides of the outer wall of the two extension blocks 3. Multiple support rods 18 are grouped in pairs, and a transmission roller 19 passes through each group of support rods 18. The two transmission rollers 19 are located on both sides of the support frame 1. The support rods 18 are metal rods and are symmetrically distributed in pairs. A transmission roller 19 passes through each group of support rods 18. The transmission rollers 19 are located on both sides of the support frame 1 and are used to smoothly guide the external yarn into the device to provide continuous yarn raw materials for the detection transmission structure.

[0029] In this embodiment, the DTY yarn is introduced through the transmission rollers 19 on both sides of the support frame 1. The transmission rollers 19 rotate under the support of the support rod 18, guiding the yarn into the interior of the support frame 1. The yarn first passes through the guide roller 11 at the bottom of the connecting seat 10, and is neatly bundled under the action of the take-up wheel 12. Then, it enters the detection box 15 through the guide port 13 and the top guide port 14, and passes around the guide detection wheel 17 to complete the tension detection before being discharged. When the yarn passes around the guide detection wheel 17, it will generate a certain tension on the guide detection wheel 17. The detector 16 monitors the change of tension on the guide detection wheel 17 in real time, converts the mechanical signal into an electrical signal, and obtains the yarn tension value after processing by the control system, realizing real-time detection. When it is necessary to adjust the detection position according to the yarn type or production process, the air pump 5 is started. The air pump 5 drives the pneumatic block 6 in the transmission seat 4 to slide. The pneumatic block 6 drives the limit slide rod 9 to move along the sliding groove 8 through the connecting block 7, which in turn drives the connecting seat 10 to slide on the inner wall of the support frame 1. The movement of the connecting seat 10 changes the position of the guide roller 11, the take-up wheel 12 and other components, so that the tension state of the yarn in the detection box 15 changes to adapt to different detection requirements.

[0030] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
