Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, specifically to a leveling and self-adjusting control device for a drawing frame. Background Technology

[0002] The drawing frame is a key piece of equipment in the spinning process, located between the carding frame and the roving frame. Its core function is to refine the fiber sliver output from the carding frame through processes such as doubling, drafting, and mixing, providing a uniform and neat fiber sliver for subsequent spinning processes. The self-regulating leveling mechanism can significantly improve yarn quality and production efficiency by monitoring and dynamically adjusting the linear density of the fiber sliver in real time.

[0003] Chinese utility model patent CN221760079U discloses a self-leveling and leveling device for textiles, including a self-leveling machine. First baffles are fixedly connected to both rear sides of the upper end of the self-leveling machine, and first motor boxes are fixedly connected to each of the first baffles. Third baffles are provided on both left and right sides of the front end of the self-leveling machine, and turntables are provided at the rear ends of the third baffles. A first motor is fixedly connected to the center of the bottom end of each turntable. In this utility model, when the yarn hairiness meter detects the "hanging" phenomenon between the concave and convex sections, the output end of the second motor rotates, positioning the air inlet at the hanging position. Then, the output end of the third electric push rod drives the air inlet to move up and down, shortening the distance between the air inlet and the hanging material. The output end of the third motor then rotates, driving the fan blades to rotate and create upward suction. This suction carries the hanging material through the suction pipe into the storage chamber, completing the hanging material treatment and preventing it from affecting the quality of the finished textile yarn.

[0004] To facilitate the removal of lint, the aforementioned self-adjusting textile leveling device is equipped with a third motor, fan blades, air inlet, air pipe, air baffle, and storage compartment. However, the aforementioned self-adjusting textile leveling device does not have the function of cleaning the air baffle. During the cleaning process, some lint may adhere to the surface of the second ventilation hole. If the air baffle is not cleaned, the lint will gradually block the pores, reduce the suction efficiency, and result in incomplete removal of lint. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model discloses a leveling and self-adjusting control device for a drawing frame, including a self-adjusting leveling machine body 1. A first baffle 201 is fixedly installed on both sides of the top of the self-adjusting leveling machine body 1. A mounting box 202 is fixedly installed in the middle of the top of the first baffle 201. A first motor 203 is installed inside the mounting box 202. A first rotating rod 204 is fixedly installed on the output shaft of the first motor 203. A second rotating rod 205 is fixedly installed on the top of one side of the first rotating rod 204. A groove is opened at the end of the second rotating rod 205 away from the first rotating rod 204, and a first electric push rod 206 is installed in the groove. A storage compartment 301 is fixedly installed at the telescopic end of the first electric push rod 206.

[0022] A second motor 302 is fixedly installed on the top of the inner wall of the storage compartment 301. A fan blade 303 is fixedly installed on the output shaft of the second motor 302. A filter screen 304 is installed inside the storage compartment 301. Support rods 305 are fixedly installed at the four corners of the bottom of the filter screen 304. A movable plate 306 is fixedly installed at one end of each support rod 305. Slider blocks 307 are fixedly installed on both sides of the movable plate 306. A return spring 308 is fixedly installed at the bottom of the movable plate 306. The movable plate 306 is externally movable. A fixed cylinder 309 is provided. One end of the return spring 308 is fixedly connected to the bottom of the inner wall of the fixed cylinder 309. A fixed block 310 is fixedly provided at the bottom of the fixed cylinder 309. One side of the fixed block 310 is fixedly connected to the inner wall of the storage compartment 301. A third motor 311 is fixedly provided on one side of the storage compartment 301. A cam 312 is fixedly provided on the output shaft of the third motor 311. A third rotating rod 401 is fixedly provided at the bottom of the storage compartment 301. A fixed box 402 is fixedly provided at one end of the third rotating rod 401.

[0023] Specifically, both sides of the inner wall of the fixed cylinder 309 are provided with sliding grooves that are adapted to the slider 307, and the connection between the fixed cylinder 309 and the slider 307 is a sliding connection.

[0024] In this embodiment, by setting up a slider 307 and a fixed cylinder 309, while the moving plate 306 moves, the slider 307 slides in the groove of the fixed cylinder 309, thereby guiding and limiting the movement of the moving plate 306.

[0025] Specifically, a collection trough 313 is movably provided at the bottom of the inner wall of the storage compartment 301.

[0026] In this implementation plan, the collection trough 313 is provided, which greatly facilitates the cleaning of the flowers by the staff, effectively improves work efficiency and reduces the workload.

[0027] Specifically, a second electric push rod 403 is provided inside the fixed box 402, and an air intake 404 is fixedly provided at the telescopic end of the second electric push rod 403.

[0028] In this embodiment, by setting a second electric push rod 403 and an air intake 404, the telescopic end of the second electric push rod 403 can drive the air intake 404 to move, thereby adjusting the height of the air intake 404.

[0029] Specifically, suction pipes 405 are fixedly installed on both sides of the air intake 404.

[0030] In this embodiment, by setting up the suction pipe 405, the airflow carrying the hanging flowers can smoothly enter the storage chamber 301, so as to facilitate the collection of the hanging flowers.

[0031] Specifically, a second baffle 406 is fixedly installed in the middle of the top of the self-leveling machine body 1, and a yarn hairiness meter 407 is fixedly installed between the second baffle 406 and the first baffle 201.

[0032] In this implementation plan, a yarn hairiness meter 407 is installed. The yarn hairiness meter 407 can detect whether there is a snagging phenomenon in the textile yarn, which helps to clean up the snagging in time and improve product quality.

[0033] When yarn lint appears during use, the yarn lint meter 407 detects it. The first motor 203 drives the first rotating rod 204 and the second rotating rod 205 to rotate, which in turn drives the storage chamber 301 and the third rotating rod 401 to rotate. Simultaneously, the telescopic end of the first electric push rod 206 retracts inward or extends outward, causing the storage chamber 301 and the third rotating rod 401 to move until the air intake 404 is directly above the lint location. The second electric push rod 403 is then activated, its telescopic end moving the air intake 404 upward or downward, thus shortening the distance between the air intake 404 and the lint location. The second motor 302 is then activated, driving the fan blades 303 to rotate, creating airflow. This air carrying the lint flows through the air intake 404 into the air intake pipe 405, and then into the storage chamber 301, thus cleaning the lint location. After filtration by filter screen 304, the gas containing the lint is discharged through the ventilation hole on one side of the top of storage chamber 301. Some of the lint falls directly into collection tank 313, while the rest adheres to the bottom of filter screen 304. The third motor 311 is started, and the output shaft of the third motor 311 drives the cam 312 to rotate, causing the protrusion of the cam 312 to periodically impact the filter screen 304. The support rod 305 moves accordingly, and the moving plate 306 moves vertically in cooperation with the slider 307 and the slide groove. The return spring 308 deforms, and the moving plate 306 periodically returns to its original position under the elastic force of the return spring 308, causing the filter screen 304 to vibrate. This shakes the lint attached to the filter screen 304 into the collection tank 313. After the collection tank 313 is full, it is pulled out and cleaned. After cleaning, it is inserted back into storage chamber 301.

[0034] In summary, the leveling and self-adjusting control device of this drawing frame, through the arrangement of a support rod 305, a moving plate 306, a slider 307, a return spring 308, a fixed cylinder 309, a fixed block 310, a third motor 311, and a cam 312, enables the third motor 311 to be started. The output shaft of the third motor 311 drives the cam 312 to rotate, causing the protrusion of the cam 312 to periodically impact the filter screen 304. The support rod 305 moves accordingly, and the moving plate 306 moves vertically in cooperation with the slider 307 and the slide groove. The return spring 308 deforms, and the moving plate 306 periodically returns to its original position under the elastic force of the return spring 308, thus ensuring that the filter screen 304... Vibration automatically cleans the filter 304, preventing clogging and ensuring smooth airflow, thus improving the efficiency and effectiveness of cleaning the hanging flowers. A collection trough 313 collects the cleaned hanging flowers at the bottom of the storage chamber 301. Once full, the trough can be removed for cleaning. After cleaning, the trough is inserted back into the storage chamber 301, allowing for quick installation and removal. This greatly simplifies the process and improves work efficiency.
