Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, specifically to a drawing frame for producing anti-tangling polyester-cotton grey fabric. Background Technology

[0002] The drawing frame is an indispensable piece of equipment in the textile industry. It is mainly used to combine, draft, and compact multiple fiber slivers to improve the internal structure of the sliver, increase the uniformity of its long segments, and reduce weight unevenness. Its working principle involves precise mechanical control to achieve the combining, stretching, and compression of the fiber slivers, thereby making the fibers straighter and more parallel, reducing hooks, and improving the fineness uniformity and quality of the yarn. In existing technology, drawing frames stretch, comb, and convey one end of multiple fiber slivers through multiple sets of longitudinally arranged upper and lower rollers. However, in the production of polyester-cotton grey fabric, polyester fibers are prone to generating static electricity after friction, which will be adsorbed on the roller surface and gradually accumulate. In addition, some short fibers may get stuck in the grooves of the rollers and are difficult to clean. This will cause subsequent fiber slivers to wrap around the rollers, affecting the drawing effect. Utility Model Content

[0003] To overcome the above-mentioned defects, the present invention provides a drawing frame for producing polyester-cotton grey fabric with anti-tangling properties, which solves the technical problem in the prior art that some short fibers may get stuck in the grooves of the rollers and are difficult to clean, which will cause the subsequent fiber slivers to entangle on the rollers and affect the drawing effect.

[0004] According to one aspect, at least one embodiment of the present invention provides a drawing frame for producing anti-tangling polyester-cotton grey fabric, comprising a drawing frame body, the drawing frame body including a worktable, a roller, a drive component, a smooth roller, a cavity, and a scraping mechanism. The worktable has multiple grooves, the roller is rotatably disposed within the grooves, the drive component is disposed on the worktable for driving the roller to rotate, the smooth roller is rotatably disposed above the roller, and a traction space is formed between the longitudinally arranged smooth roller and the roller. The worktable has the cavity, a collecting groove is slidably disposed within the cavity, and the scraping mechanism is disposed on one side of the roller for cooperating with the rotating roller to scrape short fibers adhering to the roller into the collecting groove.

[0005] Preferably, the driving component includes a drive shaft and a motor. The drive shaft is rotatably disposed within the worktable. The roller is fitted onto the drive shaft and is coaxially and fixedly connected to the drive shaft. The motor is mounted on the worktable, and the output end of the motor is coaxially and fixedly connected to one end of the drive shaft.

[0006] Furthermore, the scraping mechanism includes a mounting base, a movable plate, a fixed plate, and a scraper. The workbench has multiple slots. The mounting base is fixedly connected to the inner wall of the slots. The mounting base has a through slot that mates with the movable plate. The movable plate is movably mounted on one side of the mounting base via an elastic connector. The fixed plate is fixedly connected to one end of the movable plate. One end of the scraper is detachably mounted on the fixed plate.

[0007] Furthermore, the elastic connector includes a connecting plate and a spring. A sliding groove is provided in the mounting base, and the sliding groove is connected to the through groove. The connecting plate is slidably disposed in the sliding groove. One end of the connecting plate is fixedly connected to a plurality of springs, and the other end of the springs is fixedly connected to the inner sidewall of the sliding groove.

[0008] As a further embodiment of this application, in order to facilitate the removal of the collection tank from the workbench, a protruding plate is fixedly connected to one end of the collection tank, and a pull rod is fixedly installed on the protruding plate.

[0009] As a further improvement in this application, to prevent one end of the spring from moving out of the mounting base, the cross-sectional area of ​​the through groove is smaller than the cross-sectional area of ​​the slide groove.

[0010] Based on the aforementioned solution, in order to remove short fibers from the roller, the scraper is made of an elastic material and has a wear-resistant layer, with one end of the scraper abutting against the roller.

[0011] Furthermore, in order to facilitate the disassembly of the scraper, the fixing plate is provided with a slot that mates with the scraper, and the scraper and the fixing plate are detachably connected by locking bolts.

[0012] The beneficial effects of this utility model are as follows: In this invention, the collection trough is moved out of the worktable by cooperating with the roller, drive unit, smoothing roller, collection trough and scraping mechanism. One end of the scraper is inserted into the slot and the scraper is fixed in the fixed plate with locking bolts to facilitate scraper replacement. Then the collection trough is moved into the cavity. The fiber sliver after being drawn by the drawing mechanism is placed between the smoothing roller and the roller. Multiple motors are started at the same time to pull and convey the fiber sliver. The scraper elastically abuts against the roller, thus scraping off the short fibers attached to the roller and dropping them into the collection trough, preventing the fiber sliver from getting tangled on the roller and facilitating subsequent cleaning.

[0022] like Figures 1-6 As shown, it illustrates a drawing frame for producing anti-tangling polyester-cotton fabric in one embodiment of the present invention, including a drawing frame body 1, a workbench 2, a material preparation mechanism 22 on one side of the workbench 2 for conveying multiple fiber slivers, a drawing mechanism 23 on the workbench 2 for merging multiple fiber slivers, and also includes a roller roller 3, a drive component, a smooth roller 5, a cavity 6 and a scraping mechanism; like Figure 6As shown, the worktable 2 has multiple grooves 4, and the roller 3 is rotatably disposed in the grooves 4. The driving component is disposed on the worktable 2 and is used to drive the roller 3 to rotate. The driving component includes a drive shaft 7 and a motor 8. The drive shaft 7 is rotatably disposed in the worktable 2. The roller 3 is mounted on the drive shaft 7 and is coaxially fixedly connected to the drive shaft 7. The motor 8 is mounted on the worktable 2. The output end of the motor 8 is coaxially fixedly connected to one end of the drive shaft 7. Multiple motors 8 are controlled by the same control system. By starting multiple motors 8 at the same time, the output end of the motor 8 drives the drive shaft 7 to rotate, and the drive shaft 7 drives the roller 3 to rotate. like Figure 2 and Figure 3 As shown, a smooth roller 5 is rotatably arranged above the roller roller 3. A protective cover 24 is provided on the worktable 2. The smooth roller 5 is located inside the protective cover 24. The smooth roller 5 and the roller roller 3 arranged longitudinally form a traction space. The fiber sliver after drawing is placed between the smooth roller 5 and the roller roller 3 and abuts against the smooth roller 5 and the roller roller 3 respectively. The fiber sliver is pulled and conveyed by the rotation of the roller roller 3. A cavity 6 is opened in the worktable 2. Multiple roller rollers 3 are located above the cavity 6. A collection groove 25 is slidably arranged in the cavity 6. In order to facilitate the removal of the collection groove 25 from the worktable 2, a protruding plate 18 is fixedly connected to one end of the collection groove 25. The protruding plate 18 is slidably arranged in the worktable 2. The cross-sectional area of ​​the protruding plate 18 is the same as the cross-sectional area of ​​the collection groove 25. A pull rod 19 is fixedly arranged on the protruding plate 18. By holding the pull rod 19 and pulling the pull rod 19 outward, the pull rod 19 drives the protruding plate 18 to move, and the protruding plate 18 drives the collection groove 25 to move out of the worktable 2. like Figure 4 and Figure 5As shown, a scraping mechanism is located on one side of the roller roller 3, used to scrape the short fibers attached to the roller roller 3 into the collection trough 25 in cooperation with the rotating roller roller 3. The scraping mechanism includes a mounting base 9, a moving plate 11, a fixed plate 13, and a scraper 14. Multiple slots 10 are opened in the worktable 2, and all slots 10 are connected to the cavity 6. The mounting base 9 is fixedly connected to the inner wall of the slots 10. A through groove 12 is opened on the mounting base 9 to cooperate with the moving plate 11. The moving plate 11 is movably set on one side of the mounting base 9 by an elastic connector, which includes a connecting plate 15 and a spring 17. A sliding groove 16 is opened in the mounting base 9, and the sliding groove 16 is connected to the through groove 12. In order to prevent one end of the spring 17 from moving out of the mounting base 9, the cross-sectional area of ​​the through groove 12 is smaller than that of the sliding groove. The cross-sectional area of ​​the connecting plate 15 of the 16 is slidably disposed in the slide groove 16. One end of the connecting plate 15 is fixedly connected to a plurality of springs 17, and the other end of the springs 17 is fixedly connected to the inner side wall of the slide groove 16. In order to prevent one end of the springs 17 from moving out of the mounting seat 9, the cross-sectional area of ​​the through groove 12 is smaller than the cross-sectional area of ​​the slide groove 16. The fixing plate 13 is fixedly connected to one end of the moving plate 11. One end of the scraper 14 is detachably disposed on the fixing plate 13. In order to facilitate the removal of the scraper 14, the fixing plate 13 is provided with a slot 20 that mates with the scraper 14. The scraper 14 and the fixing plate 13 are detachably connected by locking bolts 21. In order to remove short fibers from the roller roller 3, the scraper 14 is made of elastic material and is provided with a wear-resistant layer. One end of the scraper 14 abuts against the roller roller 3. Specifically, after removing the collection trough 25 from the worktable 2, one end of the scraper 14 is inserted into the slot 20 (this pushes the fixed plate 13, causing the moving plate 11 to move towards the inside of the chute 16, and the spring 17 contracts, increasing the distance between the fixed plate 13 and the other inner wall of the slot 10, thus providing space for installing the scraper 14). The scraper 14 is then fixed in the fixed plate 13 using the locking bolt 21. The collection trough 25 is then moved into the cavity 6. The drawn fiber sliver is placed between the smooth roller 5 and the roller roller 3. Multiple motors 8 are started simultaneously. The output of the motors 8 drives the drive shaft 7 to rotate, which in turn drives the roller roller 3 to rotate. The fiber sliver is then pulled and conveyed by the smooth roller 5 and the roller roller 3. Short fibers may adhere to the roller 3. The scraper 14 elastically abuts against the roller 3. When the scraper 14 is pushed by the roller 3, the scraper 14 drives the fixed plate 13 to move toward the mounting base 9. The fixed plate 13 drives the moving plate 11 to slide along the through groove 12 and move into the slide groove 16. The moving plate 11 drives the connecting plate 15 to move along the inner wall of the slide groove 16. The connecting plate 15 compresses multiple springs 17. The multiple springs 17 contract and generate elastic force in the opposite direction. The damping coefficient of the multiple springs 17 is good. The springs 17 drive the scraper 14 to move horizontally repeatedly under the squeezing action of the roller 3. In this way, the short fibers attached to the roller 3 are scraped off and fall into the collection groove 25, avoiding the fiber strips from getting tangled on the roller 3 and facilitating subsequent cleaning. Working principle: When the anti-tangling polyester-cotton fabric production drawing frame is drawing polyester-cotton fiber slivers, the collection trough 25 is moved out of the worktable 2. One end of the scraper 14 is inserted into the slot 20 and the scraper 14 is fixed in the fixing plate 13 with the locking bolt 21. Then the collection trough 25 is moved into the cavity 6. The fiber slivers after drawing by the drawing mechanism 23 are placed between the smooth roller 5 and the roller roller 3. By starting multiple motors 8 at the same time, the output end of the motor 8 drives the drive shaft 7 to rotate. The drive shaft 7 drives the roller roller 3 to rotate. The fiber slivers are pulled and conveyed by the smooth roller 5 and the roller roller 3. Short fibers may be attached to the roller roller 3. The scraper 14 elastically abuts against the roller roller 3, thus scraping off the short fibers attached to the roller roller 3 and dropping them into the collection trough 25, preventing the fiber slivers from tangling on the roller roller 3 and facilitating subsequent cleaning.
