Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically a device for preventing yarn from being contaminated by clusters of yarn. Background Technology

[0002] Coarse yarn refers to cotton yarn with a count of 17 or lower on the second mounting plate. It is mainly used for weaving thick, coarse, or napped / looped cotton fabrics, such as muslin and flannel. Doffing is a core production process in the fine spinning workshop, referring to the spinning stage where the yarn is wound onto bobbins for setting and impurity removal, aiming to achieve high-quality, high-yield, and low-consumption production goals.

[0003] When spinning coarse yarns or yarns with high strength, the yarn tail after doffing is relatively long. When the doffing steel belt guide is running, the tail may get stuck between the yarn tube seat and the guide, causing yarn contamination and affecting yarn quality. To address this, a device is proposed to prevent yarn contamination during doffing. Utility Model Content

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] The present invention provides the following preferred embodiments:

[0030] Example 1, as Figures 1-7 As shown, a device for preventing yarn contamination caused by accumulation includes a yarn-scraping mechanism disposed on one side of track 11;

[0031] Specifically, a steel belt 12 is provided in the middle of the track 11. The steel belt 12 can move inside the track 11. Multiple bases 13 are installed at the top of the steel belt 12. Each base 13 has a yarn tube 14 at its top. When the steel belt 12 runs inside the track 11, it can be driven to move by the bases 13, so that the yarn can move. When the yarn moves, the tail yarn may get stuck between the base 13 and the track 11, causing contamination of the yarn and affecting the yarn quality. The yarn scraping plate 15 in the yarn scraping mechanism can scrape out or cut off the tail yarn embedded in the track 11, thereby avoiding friction contamination of the tail yarn in the track 11 and achieving the effect of preventing contamination of the yarn.

[0032] The yarn scraping mechanism includes a yarn scraping plate 15 and an installation assembly. The yarn scraping plate 15 is located on one side of the track 11, and the installation assembly is set between the track 11 and the yarn scraping plate 15. The installation assembly is used to enable quick installation and disassembly of the yarn scraping plate 15, so as to facilitate the cleaning of the yarn at one end of the yarn scraping plate 15 and prevent the broken yarn from accumulating at one end of the yarn scraping plate 15.

[0033] The mounting assembly includes an unlocking component, two first mounting plates 16, two second mounting plates 17, and two snap-fit ​​components. The two first mounting plates 16 are respectively fixed to one side of the track 11, and the track 11 and the first mounting plates 16 are detachably connected by bolts. Each second mounting plate 17 is located on one side of a first mounting plate 16, and each second mounting plate 17 is fixed to the inner wall of the yarn scraping plate 15. The yarn scraping plate 15 and the second mounting plate 17 are detachably connected by bolts. Each snap-fit ​​component is disposed between one first mounting plate 16 and one second mounting plate 17. The unlocking component is located between the yarn scraping plate 15 and the two snap-fit ​​components.

[0034] Two snap-fit ​​components can be used to achieve a snap-fit ​​connection between the first mounting plate 16 and the second mounting plate 17, thereby connecting the track 11 and the yarn scraping plate 15 and enabling the installation of the yarn scraping plate 15. The unlocking component can be used to release the snap-fit ​​components from the first mounting plate 16 and the second mounting plate 17, thereby enabling the disassembly of the yarn scraping plate 15.

[0035] like Figures 1-7As shown, each snap-fit ​​component includes a fixing block 18, two plug-in blocks 20, two connecting plates 21, and two side plates 26. The fixing block 18 is fixed to the side of the first mounting plate 16 near the second mounting plate 17. Plug-in slots 19 are provided on both sides of the end of the fixing block 18 near the first mounting plate 16. The two plug-in blocks 20 are respectively snapped into the interior of the two plug-in slots 19. The two connecting plates 21 are respectively fixed to the sides of the two plug-in blocks 20 that are far apart from each other. The two side plates 26 are symmetrically fixed to both sides of the second mounting plate 17.

[0036] The two side plates 26 are located on both sides of the fixing block 18 and can play a limiting role to prevent the yarn scraper plate 15 from sliding under the action of the yarn, causing the plug block 20 to slide out from one end of the fixing block 18.

[0037] Each connecting plate 21 has a slider 22 fixed at both ends. Each side plate 26 has two grooves 23 on its surface. Each slider 22 is slidably disposed inside a groove 23. Each groove 23 has a fixed rod 24 fixed inside it. Both ends of each fixed rod 24 are in contact with the inner wall of the groove 23. Each slider 22 has a sliding hole. Each slider 22 is slidably disposed on a fixed rod 24 through the sliding hole. The sliding hole allows the fixed rod 24 to pass through. Each fixed rod 24 has a first spring 25 sleeved on its outer wall. Both ends of each first spring 25 are connected to the slider 22 and the groove 23 respectively.

[0038] In the initial state, the two plug blocks 20 are respectively snapped into the inside of the two plug slots 19, and the two sliders 22 on the same side plate 26 are respectively set inside the two sliding grooves 23 at the close ends, and each first spring 25 is in the natural state.

[0039] like Figures 1-7 As shown, the unlocking component includes a pull plate 33, two pull rods 32, two fixed plates 30, two second springs 31, two moving blocks 29, and four hinge rods 27. The two side plates 26 located in the middle are provided with slide rails 28 on their sides that are close to each other. Each moving block 29 is slidably mounted on the slide rail 28. Each fixed plate 30 is located on one side of a moving block 29 and fixed to the side plate 26. Each second spring 31 is located between a fixed plate 30 and a moving block 29. Both ends of each second spring 31 are connected to the moving block 29 and the fixed plate 30, respectively. One end of each pair of hinge rods 27 is hinged to a moving block 29, and the other end of each hinge rod 27 is hinged to a slider 22.

[0040] In the initial state, the moving block 29 is located on the side away from the fixed plate 30, and the second spring 31 is in the natural state;

[0041] Two perforations 34 are provided on the surface of the yarn scraping plate 15. Two pull plates 33 are respectively inserted into the two perforations 34. One end of the two pull plates 33 is fixedly connected to the side of the two moving blocks 29 away from the fixed plate 30. The pull plates 33 are fixed to the end of the two pull rods 32 away from the moving blocks 29.

[0042] When it is necessary to remove the yarn scraping plate 15 from the track 11, press the pull plate 33 to move the pull plate 33 toward the yarn scraping plate 15. When the pull plate 33 moves, it can drive the two moving blocks 29 to move toward the fixed plate 30 on the slide rail 28 through the two pull rods 32. At this time, the second spring 31 is compressed. When the moving block 29 moves, it can drive the two sliders 22 on the same first mounting plate 16 to move away from each other through the hinge rod 27. The first spring 25 is compressed. When the slider 22 moves, it can drive the two plug blocks 20 on both sides of the fixed block 18 to move away from each other through the connecting plate 21, so that the plug blocks 20 can be moved out from the inside of the plug slot 19. Then, move the yarn scraping plate 15 to remove the second mounting plate 17 from one side of the first mounting plate 16, thus realizing the disassembly of the yarn scraping plate 15.

[0043] When the yarn scraping plate 15 needs to be reinstalled, the two second mounting plates 17 are aligned with the two first mounting plates 16 respectively, and the yarn scraping plate 15 is pressed down, so that the yarn scraping plate 15 moves towards the track 11. During the movement, the plug-in block 20 first contacts the fixing block 18. As the yarn scraping plate 15 continues to move, the plug-in block 20 moves to one side of the fixing block 18. At this time, the first spring 25 is gradually compressed. When the plug-in block 20 moves to one side of the plug-in groove 19, the slider 22 can be reset under the action of the first spring 25, so that the plug-in block 20 can be inserted into the interior of the plug-in groove 19, realizing the snap-fit ​​between the first mounting plate 16 and the second mounting plate 17, thereby realizing the quick installation of the yarn scraping plate 15.

[0044] like Figures 1-7 As shown, the fixing block 18 has a first inclined surface on both sides of the end near the second mounting plate 17, and each plug-in block 20 has a second inclined surface on the end near the fixing block 18.

[0045] like Figures 1-7 As shown, each plug block 20 has two receiving grooves 35 on its second inclined surface. Each receiving groove 35 has a rotating roller 36 rotatably installed inside it. By setting the rotating roller 36, when the fixed block 18 contacts the plug block 20, the rotating roller 36 on one side of the plug block 20 can reduce the friction between the plug block 20 and the fixed block 18.

[0046] To further improve the cutting effect on the tail yarn, this application provides another implementation method;

[0047] Example 2, as Figure 8 As shown, one end of the yarn-cutting plate 15 is provided with a shearing edge 37, which is integrally formed with the yarn-cutting plate 15. Specifically, the end of the shearing edge 37 away from the yarn-cutting plate 15 is sharp, which can improve the yarn-cutting effect of the tail yarn.

[0048] The beneficial effects of this utility model are specifically reflected in the fact that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
