Description

Technical Field

[0001] This application relates to the field of drawing frame technology, specifically a high-speed drawing frame for self-regulating and leveling cotton yarn. Background Technology

[0002] A drawing frame is a spinning machine that processes several combed or combed fiber slivers into fiber slivers with certain quality requirements. The function of the drawing frame is to improve the internal structure of the sliver, thereby increasing its long segment uniformity, reducing weight unevenness, straightening and paralleling the fibers in the sliver, reducing hooks, ensuring the fineness meets the specifications, and mixing different types or qualities of raw materials evenly to achieve the specified mixing ratio.

[0003] However, most existing drawing frames lack a device to adjust the tension of the sliver. Different fibers have slightly different elasticity and elongation. The lack of a tension adjustment device will cause the fiber sliver to be overstretched or relaxed during the drawing process, affecting the straightness, parallelism and mixing uniformity of the fibers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a high-speed drawing frame for self-regulating cotton yarn, which has advantages such as tension adjustment. It solves the problem that most existing drawing frames lack a device to adjust the tension of the sliver. Different fibers have slightly different elasticity and elongation rates, and the lack of a tension adjustment device will cause the fiber sliver to be overstretched or relaxed during the drafting process, affecting the straightness, parallelism, and mixing uniformity of the fibers.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-speed drawing frame for self-regulating and leveling cotton yarn, comprising a base plate, a slide plate, and two first rotating seats. The base plate has grooves on both sides of its interior. Slide strips are fixedly connected to both sides of the slide plate. Two sets of storage bins are fixedly connected to the upper end of the slide plate. A vertical plate is fixedly connected to one side of the upper end of the base plate. A support plate is fixedly connected to the upper end of one side of the vertical plate. Two dividing pipes arranged in a mirror image are fixedly connected to both sides of the support plate. Two fixing blocks are fixedly connected to both sides of the support plate. FP sensors are fixedly connected to the ends of the four fixing blocks away from the support plate. A first threading pipe is fixedly connected to one side of the upper end of the support plate. A second threading pipe is fixedly connected to the end of the upper end of the support plate away from the first threading pipe. Two positioning grooves arranged in a mirror image are opened inside the support plate. A moving plate is fixedly connected to the bottom end of the two positioning grooves. Two electric push rods arranged in a mirror image are fixedly connected to the bottom end of the support plate. An adjusting roller is rotatably connected between the two first rotating seats.

[0006] The above scheme uses FP sensors to monitor the tension, thickness, and speed of the fiber strip in real time, transmitting the data to the control device. When an abnormality is detected, the electric push rod is driven to retract, thereby moving the moving plate and causing the first rotating seat to slide in the positioning groove. This adjusts the position of the adjusting roller, changes the tension of the fiber strip, ensures stable tension, and avoids unevenness or breakage. The splitting tube separates multiple fiber strips and guides them to designated paths, reducing cross-interference. The first and second threading tubes are used for the input and output of the fiber strips, forming a clear processing path and preventing the fiber strips from derailing or tangling during high-speed operation. The slide plate slides in the groove of the base plate via a slide bar, enabling rapid positioning and replacement of the storage bin. The two sets of storage bins can be used alternately, reducing downtime and improving production continuity.

[0007] Furthermore, two second rotating seats are fixedly connected to one side of the upper end of the support plate, and two dividing rollers arranged in a mirror image are rotatably connected between the two second rotating seats.

[0008] With the above scheme, two splitting rollers are mounted on one side of the upper end of the support plate via the second rotating seat, which can process multiple fiber strips at the same time, reduce cross friction between fibers, and ensure that each fiber strip passes through independently without interfering with each other.

[0009] Furthermore, a control box is fixedly connected to one side of the upright plate.

[0010] The above method receives data from the FP sensor and dynamically adjusts the extension and retraction of the electric actuator based on the real-time data from the FP sensor.

[0011] Furthermore, the end of the support plate away from the upright plate is fixedly connected to the drawing frame body, and one side of the base plate is fixedly connected to the drawing frame body.

[0012] The above solution achieves highly stable processing by rigidly connecting the drawing frame body with the support plate and base plate to form an integrated mechanical structure.

[0013] Furthermore, each of the four branch pipes has a through slot inside, and each of the four FP sensors corresponds to a through slot.

[0014] Using the above method, the FP sensor illuminates the fiber strip through a through-slot to monitor the fiber strip in real time.

[0015] Furthermore, the slide plate is slidably disposed inside the base plate, the two slide bars are slidably disposed inside the slide groove, and the two sets of storage bins are arranged in a rectangular array of four and fixed to the upper end of the slide plate.

[0016] With the above scheme, the bottom of the slide plate is embedded in the groove of the base plate by two sliding strips to ensure the linear movement of the slide plate. The two sets of storage bins can be used alternately. During production, one set of storage bins corresponds to the distribution pipe for material supply, while the other set of storage bins is in standby state and can be loaded with raw materials in advance.

[0017] Furthermore, both of the first rotating seats are slidably disposed inside the positioning groove, and the output ends of the two electric push rods are fixedly connected to the moving plate.

[0018] With the above scheme, the two first rotating seats are slidably set in the positioning groove to ensure the stability of the first rotating seats when sliding. The two electric push rods are symmetrically arranged, and their output ends are connected to the moving plate. The first rotating seats are driven to rise and fall through the two electric push rods.

[0019] Furthermore, the control box is electrically connected to four FP sensors and two electric actuators, respectively.

[0020] Through the above scheme, the data collected by the FP sensor is transmitted to the control box. After analysis by the control box, the extension and retraction of the electric actuator is driven to adjust the tension of the fiber strip.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This high-speed drawing frame for self-leveling cotton yarn uses an FP sensor to monitor the tension, thickness, or speed of the fiber sliver in real time, transmitting the data to the control device. When an anomaly is detected, the electric push rod is retracted, which in turn moves the moving plate and causes the first rotating seat to slide within the positioning groove. This adjusts the position of the adjusting roller, changes the tension of the fiber sliver, ensures stable tension, and avoids unevenness or breakage. The separating tube separates multiple fiber slivers and guides them to designated paths, reducing cross-interference. The first and second threading tubes are used for fiber sliver input and output, respectively, forming a clear processing path and preventing the fiber slivers from derailing or tangling during high-speed operation. The slide plate slides within the groove of the base plate via a slide bar, enabling rapid positioning and replacement of the storage bin. Two sets of storage bins can be used alternately, reducing downtime and improving production continuity. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a high-speed self-leveling cotton yarn drawing frame includes a base plate 1, a slide plate 3, and two first rotating seats 14. The base plate 1 has grooves 2 on both sides. Slide plates 4 are fixedly connected to both sides of the slide plate 3. Two sets of storage bins 5 are fixedly connected to the upper end of the slide plate 3. A vertical plate 6 is fixedly connected to one side of the upper end of the base plate 1. A support plate 7 is fixedly connected to the upper end of one side of the vertical plate 6. Two dividing pipes 8, arranged in a mirror image, are fixedly connected to both sides of the support plate 7. The dividing pipes 8 separate multiple fiber strips and guide them to a designated path, reducing cross-interference. Two fixing blocks 9 are fixedly connected to both sides of the support plate 7. FP sensors 10 are fixedly connected to the ends of the four fixing blocks 9 furthest from the support plate 7. The FP sensors 10 monitor the tension, thickness, or movement speed of the fiber strips in real time and transmit the data to the control device. A first rotating seat 14 is fixedly connected to one side of the upper end of the support plate 7. A first threading tube 11 is provided, and a second threading tube 12 is fixedly connected to the upper end of the support plate 7 away from the first threading tube 11. The first threading tube 11 and the second threading tube 12 are used for the input and output of the fiber strip, forming a clear processing path to prevent the fiber strip from derailing or tangling during high-speed operation. Two positioning grooves 13 are opened inside the support plate 7 and are arranged in a mirror image. A moving plate 15 is fixedly connected to the bottom of the two positioning grooves 13. Two electric push rods 16 are fixedly connected to the bottom of the support plate 7 and are arranged in a mirror image. An adjusting roller 17 is rotatably connected between the two first rotating seats 14. When an abnormality is detected, the electric push rod 16 is driven to retract, thereby driving the moving plate 15 and causing the first rotating seat 14 to slide in the positioning groove 13, thereby adjusting the position of the adjusting roller 17, changing the tension of the fiber strip, ensuring stable tension, and avoiding unevenness or breakage of the fiber strip.

[0032] Please see Figure 1 , Figure 3 and Figure 4 Two second rotating seats 18 are fixedly connected to one side of the upper end of the support plate 7. Two dividing rollers 19 arranged in a mirror image are rotatably connected between the two second rotating seats 18. The two dividing rollers 19 are installed on one side of the upper end of the support plate 7 through the second rotating seats 18, which can process multiple fiber strips at the same time, reduce cross friction between fibers, and ensure that each fiber strip passes independently and does not interfere with each other. A control box 20 is fixedly connected to one side of the upright plate 6 to receive data from the FP sensor 10. Based on the real-time data of the FP sensor 10, the extension and retraction of the electric push rod 16 are dynamically adjusted. The end of the support plate 7 away from the upright plate 6 is fixedly connected to the drawing frame body 21. One side of the bottom plate 1 is fixedly connected to the drawing frame body 21. By rigidly connecting the drawing frame body 21 with the support plate 7 and the bottom plate 1, an integrated mechanical structure is formed, realizing the high stability of the equipment. A through groove 801 is provided inside each of the four dividing pipes 8. Each of the four FP sensors 10 corresponds to the through groove 801. The FP sensor 10 irradiates the fiber strip through the through groove 801 to monitor the fiber strip in real time.

[0033] Please see Figure 2 , Figure 3 and Figure 5 The slide plate 3 is slidably disposed inside the base plate 1, and two sliding strips 4 are slidably disposed inside the slide groove 2. Two sets of storage bins 5, four in each set, are arranged in a rectangular array and fixed to the upper end of the slide plate 3. The bottom of the slide plate 3 is embedded in the slide groove 2 of the base plate 1 via two sliding strips 4, ensuring the linear movement of the slide plate 3. The two sets of storage bins 5 can be used alternately. During production, one set of storage bins 5 corresponds to the distribution pipe 8 for material supply, while the other set of storage bins 5 is in standby mode and can be pre-loaded with raw materials. Both first rotating seats 14 are slidably disposed inside the positioning groove 13, and the output ends of the two electric push rods 16 are connected to... The movable plate 15 is fixedly connected, and the two first rotating seats 14 are slidably set in the positioning groove 13 to ensure the stability of the first rotating seats 14 when sliding. The two electric push rods 16 are symmetrically arranged, and their output ends are connected to the movable plate 15. The first rotating seats 14 are driven to rise and fall by the two electric push rods 16. The control box 20 is electrically connected to the four FP sensors 10 and the two electric push rods 16 respectively. The data collected by the FP sensors 10 is transmitted to the control box 20. After analysis by the control box 20, the extension and retraction of the electric push rods 16 are driven to adjust the tension of the fiber strip.

[0034] In this embodiment, the FP sensor 10 monitors the tension, thickness, or movement speed of the fiber strip in real time and transmits the data to the control device. When an abnormality is detected, the electric push rod 16 is driven to retract, thereby driving the moving plate 15 and the first rotating seat 14 to slide in the positioning groove 13, thereby adjusting the position of the adjusting roller 17, changing the tension of the fiber strip, ensuring tension stability, and avoiding unevenness or breakage. The splitting tube 8 separates multiple fiber strips and guides them to a designated path, reducing cross-interference. The first threading tube 11 and the second threading tube 12 are used for the input and output of the fiber strip, respectively, forming a clear processing path and preventing the fiber strip from derailing or tangling during high-speed operation. The slide plate 3 slides in the sliding groove 2 of the base plate 1 through the slide bar 4, realizing the rapid positioning and replacement of the storage bin 5. The two sets of storage bins 5 can be used alternately, reducing downtime and improving production continuity.

[0035] The working principle of the above embodiments is as follows:

[0036] After the equipment starts, multiple fiber strips are drawn out from the storage bin 5 and separated and guided by the dividing pipe 8 to avoid cross-interference. Then, the fiber strips pass through the adjusting roller 17 and the dividing roller 19 in sequence. During this process, four FP sensors 10 monitor the tension and movement speed of the fiber strips in real time through the through groove 801 and feed the data back to the control box 20. When abnormal fiber strip tension is detected, the control box 20 immediately drives two electric push rods 16 to move synchronously. The moving plate 15 drives the first rotating seat 14 to slide in the positioning groove 13, thereby dynamically adjusting the height position of the adjusting roller 17, changing the path length of the fiber strip, realizing tension compensation, and ensuring that the fiber strips maintain constant tension during high-speed operation, avoiding unevenness or breakage. At the same time, the slide plate 3 slides with the sliding groove 2 of the base plate 1 through the sliding strip 4, so that the two sets of storage bins 5 can be alternately positioned to the working position. When one set is feeding, the other set can be pre-loaded with fiber strips, realizing material change without stopping the machine and significantly improving production efficiency.
