Description

Technical Field

[0001] This utility model relates to the field of polyester, specifically a device for stabilizing the tension of polyester colored yarn during drawing. Background Technology

[0002] In the production process of polyester colored yarn, the stability of the drawing tension plays a decisive role in the product quality. In the early polyester colored yarn drawing process, less emphasis was placed on tension control, and simple adjustments were made based on manual experience, resulting in inconsistent product quality and a high defect rate.

[0003] Some existing polyester colored filament drawing tension stabilization devices use simple mechanical structures to adjust tension, relying solely on fixed rollers or counterweights to maintain tension. These devices cannot make real-time and precise adjustments based on the actual changes in polyester colored filaments during the drawing process. When there are fluctuations in raw material characteristics or changes in equipment operating speed during production, these devices cannot guarantee the stability of colored filament tension, resulting in uneven filament thickness and surface defects, which seriously affects the subsequent processing performance and finished product quality. Therefore, we propose a polyester colored filament drawing tension stabilization device. Summary of the Invention

One end of the output shaft of the motor 7 passes through the column 2 4 and is rotatably connected to the column 2 4. One end of the output shaft of the motor 7 is fixedly connected to one end of the active cylinder 6. A C-shaped bracket 3 is fixedly connected to the side of the base plate 1 connected to the column 1 2. The two ends of the two symmetrical folded edges of the C-shaped bracket 3 are fixedly connected to the base plate 1. The C-shaped bracket 3 is located between the two guide tubes 5. The C-shaped bracket 3 is equipped with a tension adjustment structure and a locking structure.

[0024] Furthermore, the tension adjustment structure includes a tension cylinder 8, a slide groove 9, a bearing seat 10, a pressure sensor 23, and a C-shaped plate 11. Bearing seats 10 are fixedly installed at both ends of the tension cylinder 8. Each bearing seat 10 has a protrusion fixedly connected to its side facing away from the tension cylinder 8. Slide grooves 9 are formed on the inner walls of the two symmetrical folded edges of the C-shaped bracket 3. The bearing seats 10 are located between the C-shaped brackets 3, and the protrusions of the bearing seats 10 are slidably connected to the slide grooves 9. The axis of the tension cylinder 8 is parallel to the axis of the guide tube 5. A C-shaped plate 11 is fixedly connected to the side of each bearing seat 10 facing away from the base plate 1. The C-shaped plate 11 is symmetrical. The two ends of the two folded edges are fixedly connected to the bearing seat 10. A pressure sensor 23 is embedded in the cylindrical surface of the tension cylinder 8. The pressure sensor 23 is inside the tension cylinder 8 on the side near the base plate 1.

[0025] Furthermore, the tension adjustment structure also includes an adjustment tube 12, an annular protrusion 17, a threaded rod 13, a threaded hole 21, and a protrusion 18. The adjustment tube 12 is fixedly connected to the side of the C-shaped plate 11 facing away from the tension cylinder 8. An annular protrusion 17 is fixedly connected to the end of the adjustment tube 12 facing away from the opening of the C-shaped plate 11.

When threaded rod 13 rotates relative to threaded hole 21, threaded rod 13 moves up and down relative to C-shaped bracket 3, thereby driving C-shaped plate 11 and tension cylinder 8 to move up and down. Polyester colored yarn passes over the upper side of guide cylinder 5 and active cylinder 6. Motor 7 rotates to make active cylinder 6 rotate, thereby driving polyester colored yarn to one side of active cylinder 6. At this time, the lower side of tension cylinder 8 rubs against polyester colored yarn. Pressure sensor 23 measures the tension of polyester colored yarn drawing. When the tension of polyester colored yarn changes during the conveying process, the tension cylinder 8 is lowered by rotating threaded rod 13 to open up polyester colored yarn, thereby adjusting the tension of polyester colored yarn drawing. The data of pressure sensor 23 is read in real time, and the height of tension cylinder 8 is adjusted to keep the tension of polyester colored yarn drawing stable during the conveying process. Manually rotating threaded rod 13 makes the tension adjustment more precise and avoids damage to polyester colored yarn.

[0026] Furthermore, the locking structure includes a second locking hole 22 and a telescopic groove 14. The telescopic groove 14 is provided in the middle folded edge of the C-shaped bracket 3.

[0027] Furthermore, the locking structure also includes a limiting plate 19 and a locking hole 20. The limiting plate 19 is fixedly connected to the cylindrical surface of the threaded rod 13. The limiting plate 19 is located between the telescopic grooves 14. A set of evenly distributed locking holes 20 are opened through the side of the limiting plate 19 away from the protrusion 18. The number of locking holes 20 and locking holes 22 is the same, and the axis of locking holes 20 is parallel to the axis of locking holes 22. The limiting plate 19 moves up and down in the telescopic groove 14. When the locking holes 20 and locking holes 22 are coaxially aligned, they are used to install the locking structure.

[0028] Furthermore, a limiting rod 16 is inserted between locking hole 1 20 and locking hole 22. A ring rod 15 is fixedly connected to one end of each limiting rod 16 outside the C-shaped bracket 3. The limiting rod 16 is used to lock the threaded rod 13 and threaded hole 21 in the locking hole 1 20 and locking hole 22 to prevent rotation, thus ensuring the height stability of the tension cylinder 8. The ring rod 15 is used to connect the limiting rod 16, making it convenient to quickly remove and insert the limiting rod 16.

[0050] Threaded hole 21: It is opened through the C-shaped bracket 3 on the side opposite to the adjusting tube 12, and is used to connect with the threaded rod 13 to realize the up and down movement adjustment of the threaded rod 13;

[0051] Locking Hole 22: A set of holes evenly distributed around the circumference of the C-shaped bracket 3 on the side opposite to the tension cylinder 8, extending into the interior of the C-shaped bracket 3 and penetrating the telescopic groove 14, cooperating with Locking Hole 20, used to install the limiting rod 16 and lock the position of the threaded rod 13.

[0052] Pressure sensor 23: Embedded inside the cylindrical surface of tension cylinder 8 near the bottom plate 1, it detects the tension of the polyester colored yarn drawn on the surface of tension cylinder 8 in real time, providing data for operators to adjust the tension.

[0053] Working principle: When the device is running, motor 7 starts, and its output shaft drives the active cylinder 6 to rotate. Polyester filaments pass over the guide cylinder 5 and the upper side of the active cylinder 6. The rotation of the active cylinder 6 drives the polyester filaments towards one side of the active cylinder 6. The guide cylinder 5 guides the direction of the filaments. During the conveying process, the lower side of the tension cylinder 8 rubs against the polyester filaments. The pressure sensor 23, installed inside the cylindrical surface of the tension cylinder 8 near the bottom plate 1, detects the tension of the polyester filaments passing over the surface of the tension cylinder 8 in real time. When fluctuations in raw material characteristics or changes in equipment operating speed cause changes in the tension of the polyester filaments during conveying, the pressure sensor 23 can detect these changes. The pressure sensor 23 detects a change in the tension of the polyester yarn in a timely manner. The operator can adjust the tension by manually rotating the threaded rod 13 with a handle. Since the threaded rod 13 is threadedly connected to the threaded hole 21 on the C-shaped bracket 3, and the protrusion 18 at the end of the threaded rod 13 engages with the annular protrusion 17 inside the adjusting tube 12, when the threaded rod 13 rotates relative to the threaded hole 21, it moves up and down relative to the C-shaped bracket 3. This up-and-down movement of the threaded rod 13 causes the connected C-shaped plate 11 to move up and down. The C-shaped plate 11 is connected to two bearing seats 10, which are installed at both ends of the tension cylinder 8. Therefore, ultimately... This will cause the tension cylinder 8 to move up and down. If the tension decreases, the operator can rotate the threaded rod 13 to lower the tension cylinder 8, thereby opening the polyester filament and increasing its tension. If the tension increases, the threaded rod 13 is rotated in the opposite direction to raise the tension cylinder 8, appropriately reducing the tension of the filament. During the adjustment process, the operator can read the data from the pressure sensor 23 in real time. By continuously adjusting the height of the tension cylinder 8, the tension of the polyester filament is kept stable during the conveying process. This manual adjustment method of rotating the threaded rod 13 can more accurately control the tension and avoid damage to the polyester filament due to over-adjustment. When the tension cylinder 8 is adjusted to a suitable height by rotating the threaded rod 13, the polyester filament... After achieving stable tension, the position of the tension cylinder 8 needs to be locked to prevent it from changing due to external vibrations or other factors. Since the limiting plate 19 is fixed on the cylindrical surface of the threaded rod 13 and moves up and down in the telescopic groove 14, after the height of the tension cylinder 8 is adjusted, the locking hole 20 on the limiting plate 19 will be coaxially aligned with the locking hole 22 on the C-shaped bracket 3. At this time, the operator can insert the limiting rod 16 into the corresponding locking hole 20 and locking hole 22 through the ring rod 15, thereby locking the relative position between the threaded rod 13 and the threaded hole 21, ensuring the height of the tension cylinder 8 is stable, and thus maintaining the stable tension of the polyester colored yarn drawing.
