Description

Technical Field

[0001] The utility model relates to the field of drawing frames, in particular to a cotton scraping device for a drawing frame. Background Art

[0002] The function of the draw frame is to improve the internal structure of the sliver, thereby improving the uniformity of its long segments, while reducing the weight unevenness, making the fibers in the sliver straight and parallel, reducing hooks, making the fineness meet the requirements, and making the raw materials of different types or qualities mix evenly to achieve the specified mixing ratio. The draw frame is divided into two categories according to the form of the drafting mechanism: roller drafting draw frame and needle combing machine. During the operation of the draw frame, as the cotton strips enter, cotton wool will be entangled in many places inside the draw frame. Such cotton wool will not only make the draw frame run poorly, but also cause the draw frame to malfunction after long-term use. This requires the use of a cotton scraping device.

[0003] After searching, a high-efficiency cotton scraping device for a drawing frame with a publication number of CN211005771U is disclosed, which specifically discloses a high-efficiency cotton scraping device for a drawing frame, including a cotton scraping device main body, a cleaning mechanism and a disassembly mechanism, the cotton scraping device main body including a fan, a mounting bracket, an air inlet pipe, a cotton scraping box, a motor, a collecting box, a connecting rod and a rotating shaft, the cleaning mechanism including a mounting block, the filter plate is located on one side of the bottom end of the air inlet pipe, the collecting box is located at the bottom end of the air inlet pipe, the mounting block is located inside the collecting box, a dovetail groove begins to be formed on the top surface of the mounting block, a brush plate is provided at the top of the collecting box, bristles are provided at the top of the brush plate, and the bristles are located at the bottom end of the filter plate; by adding a dovetail block at the bottom end of the brush plate, when the excessively worn bristles need to be replaced, the maintenance cost of the cotton scraping device main body is reduced, and by adding a connecting ring A and a connecting ring B at the bottom end of the connecting rod and the top end of the rotating shaft respectively, the efficiency of the staff in maintaining the cotton scraping device main body is improved, and the time cost is shortened.

[0004] In the above patent, only the scraping device body, cleaning mechanism and disassembly mechanism are used to replace the excessively worn bristles, thereby reducing the maintenance cost of the scraping device body, improving the efficiency of the staff in maintaining the scraping device body, and shortening the time cost. However, during the use of the scraping device for the drawing frame, the cotton wool on the outside of the drawing frame is simply adsorbed and scraped, and the cotton roller inside the drawing frame cannot be cleaned. This cannot fully complete the cotton scraping work of the drawing frame, and it is still necessary to manually disassemble the drawing frame to take out the cotton roller for manual cleaning. This is inconvenient for scraping the cotton on the entire drawing frame, which not only increases the labor intensity of the workers, but also reduces the scope of use of the scraping device.

[0005] Therefore, it is necessary to invent a cotton scraping device for a drawing frame to solve the above problems. Utility Model Content

After long-term use, there is no need for workers to disassemble the drawing bin 2 for cleaning. The cotton rolling fan blades 15 can be driven by the driving motor 13 to rotate, and the cotton wool contaminated at the entrance of the cotton strips of the drawing bin 2 can be collected and rotated through the grooves on the cotton rolling fan blades 15 during rotation. Then, the three groups of electric slide rails 10 inside the upper bin cover 9 drive the cotton cleaning brush 12 to sweep back and forth above the three groups of cotton drawing rollers 16 to complete the cotton wool cleaning work on the cotton drawing rollers 16.

[0026] like Figure 1 and Figure 2As shown, a first servo motor 3 is arranged at the bottom of the machine body 1, and the output end of the first servo motor 3 is fixedly connected to the first transmission gear 4, and the first cotton feed disc 5 is fixedly installed above the first transmission gear 4.
