Description

Technical Field

[0001] The present application relates to the technical field of spinning draw frames, and in particular to a cleaning device for a spinning draw frame. Background Art

[0002] The function of the spinning and drawing frame is to improve the internal structure of the sliver, thereby improving its long segment uniformity, while reducing weight unevenness, making the fibers in the sliver straight and parallel, reducing hooks, making the fineness meet the requirements, and making raw materials of different types or qualities mix evenly to achieve the specified mixing ratio.

[0003] When processing combed cotton yarn, the draw frame cleaning device is designed to promptly remove flying fibers and dust adhering to the surfaces of the top rollers within the draw mechanism, preventing them from accumulating and falling into the sliver, causing yarn defects. A commercially available draw frame cleaning device employs a cleaning belt positioned at a fixed point on one side of the top roller. The cleaning belt contacts the outer surface of the top roller, and during operation, the top roller rotates relative to the cleaning belt, which wipes and cleans the roller surface. However, as the cleaning process continues, flying fibers and dust continue to adhere to the cleaning belt. When excessive amounts of flying fibers and dust accumulate, secondary contamination of the top rollers may occur. Utility Model Content

[0021] The present application is further described in detail below with reference to the accompanying drawings.

[0022] An embodiment of the present application discloses a cleaning device for a spinning drawing frame.

[0023] Reference Figure 1 、 Figure 2 The cleaning device of the spinning draw frame includes a top roller 1 and a feed roller 2 rotatably mounted on a frame. The rotation axes of the top roller 1 and the feed roller 2 are arranged horizontally and parallel to each other, and the outer walls of the top roller 1 and the feed roller 2 are close to each other. The cleaning device of the spinning draw frame also includes a mounting frame 3 on one side for being fixedly mounted on the frame. The mounting frame 3 is fixedly mounted with mounting plates 30 located on both sides of the top roller 1. The upper half of the top roller 1 is rotatably set between the mounting plates 30 on both sides.

[0024] like Figure 2 、 Figure 3 As shown, dust covers 5 for covering the outside of the top roller 1 are installed above the mounting plates 30 on both sides. One side of the dust cover 5 is rotatably mounted on the opposite mounting plate 30, and the length of the rotating axis of the dust cover 5 extends along the length of the rotating axis of the top roller 1. A locking assembly 8 is installed on the other side of the dust cover 5, and the dust cover 5 is locked to the mounting plate 30 on the other side via the locking assembly 8.

[0025] like Figure 2 、 Figure 3 As shown, the locking assembly 8 includes a screw 80 fixedly mounted on the bottom of the dust cover 5 and a fastener 81 threadedly connected to the outside of the screw 80. In this embodiment, the fastener 81 is a nut. Clearance holes 82 are formed through the side wall of the mounting plate 30 facing the screw 80, allowing passage of the corresponding screws 80. The clearance holes 82 are located in the rotational path of the corresponding screws 80. When the dust cover 5 is placed over the roller 1, the screws 80 are inserted into their respective clearance holes 82, and the bottoms of the screws 80 pass through the outer wall of the mounting plate 30 to the outside of the mounting plate 30. Finally, the fastener 81 is tightened onto the screw 80, pressing against the bottom wall of the mounting plate 30. At this point, the dust cover 5 is locked to the mounting plate 30.

[0026] like Figure 2 、 Figure 3 As shown, a lifting plate 50 is installed within the dust cover 5. A brush 6 is fixedly mounted on the side of the lifting plate 50 facing the top roller 1. The brush 6 is used to clean the surface of the top roller 1. An adjustment rod 51 is pivotally mounted on the side of the lifting plate 50 facing away from the brush 6. The adjustment rod 51 extends from the outer wall of the dust cover 5 to the outside of the dust cover 5 and is threadedly connected to the dust cover 5. The adjustment rod 51 is used to move the brush 6 upward or downward within the dust cover 5, toward or away from the bottom roller 1. By adjusting the distance between the brush 6 and the surface of the top roller 1, the brush 6 can be adapted to clean the surfaces of top rollers 1 of varying diameters.

[0027] like Figure 2 、 Figure 3 As shown, a Velcro 52 is fixedly mounted on the inner sidewall of the dust cover 5 facing the derma roller 1. The Velcro 52 extends along the length of the derma roller 1. A cleaning tape 4 is detachably attached to the inner sidewall of the dust cover 5 via the Velcro 52. The side of the cleaning tape 4 facing away from the Velcro 52 contacts and adheres to the surface of the derma roller 1. The cleaning tape 4 is used to wipe and clean the surface of the derma roller 1.

[0028] After releasing the lock of the dust cover 5 by the locking assembly 8, the dust cover 5 is rotated away from the leather roller 1. At this time, the dust cover 5 can be opened, and then the cleaning tape 4 can be removed from the Velcro 52 to facilitate the replacement of the cleaning tape 4, thereby ensuring the cleaning effect of the cleaning tape 4.

[0029] like Figure 2 、 Figure 3As shown, an exhaust seat 7 is fixedly mounted on the outer wall of the dust cover 5, and the exhaust port of the exhaust seat 7 is connected to the interior of the dust cover 5. An exhaust pipe 70 is connected to the exhaust seat 7, and the other end of the exhaust pipe 70 is used to connect to an external exhaust device. During operation, the exhaust pipe 70 creates a negative pressure inside the exhaust seat 7. The exhaust seat 7 and the cleaning belt 4 are respectively located on either side of the top roller 1.

[0030] like Figure 2 、 Figure 3 As shown, the mounting frame 3 is also fixedly mounted with multiple guide posts 9 located outside the dust cover 5. The guide posts 9 are evenly spaced along the length of the rotating shaft of the top roller 1. A feed channel 90 for the carded slivers is formed between two adjacent guide posts 9, with the opening of the feed channel 90 facing the feed roller 2. By sequentially confining the carded slivers within their respective feed channels 90, the carded slivers are guided, ensuring that each carded sliver is smoothly conveyed between the top roller 1 and the feed roller 2.

[0031] like Figure 1 、 Figure 2 As shown, the top of each guide column 9 is detachably mounted with a same limiting plate 91, which is used to limit the carded cotton strips in their respective feeding channels 90, thereby effectively preventing the carded cotton strips from detaching from the upper opening of the feeding channel 90 during the feeding process.

[0032] The operating principle is as follows: during operation, the top roller 1 is rotated from the mounting plate 30 near the exhaust seat 7 into the dust cover 5. At this time, the exhaust seat 7 generates a negative pressure due to the action of the exhaust pipe 70, which draws most of the dust and debris adhering to the surface of the top roller 1 into the exhaust seat 7 and ultimately discharges it from the exhaust seat 7 through the exhaust pipe 70. Some stubborn dust and debris are removed from the surface of the top roller 1 by the action of the rear brush 6, and the removed dust and debris are also drawn into the exhaust seat 7. This ensures that the vast majority of dust and debris are removed from the top roller 1. Finally, the cleaning belt 4 is used to wipe the surface of the top roller 1 for the final time, thus ensuring the cleanliness of the surface of the top roller 1. This effectively reduces the accumulation of dust and debris on the surface of the cleaning belt 4, and reduces the impact of secondary contamination of the top roller 1 by dust and debris.

[0033] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
