DETAILED DESCRIPTION

[0021] The following is a further explanation of the technical solution of the utility model in conjunction with the accompanying drawings:

[0022] like Figure 1-Figure 5 As shown, a cotton feeding device for a cotton carding machine comprises a base 1, four support rods 11 are evenly fixed on the upper end of the base 1, the tops of the four support rods 11 are fixedly connected to a conveying box 2, a power device 4 is fixed on one side of the base 1, the power device 4 is connected to a conveying mechanism 3 arranged in the conveying box 2 through a belt 41, a conveyor belt 31 is installed on the conveying mechanism 3, and gaps are respectively provided between the conveying mechanism 3 and the top wall and the bottom wall of the conveying box 2, so as not to affect the normal transmission of cotton, a feed port 21 is provided on one side of the upper end of the conveying box 2, a discharge port is provided on the side away from the feed port 21, the discharge port is located at the bottom of the conveying box 2, and a discharge pipe 5 is fixedly installed at the discharge port, the discharge pipe 5 is connected to a cotton carding machine body 6, a driving mechanism is provided on the upper end of the conveying box 2, and the driving mechanism is connected to a cotton scraping mechanism arranged inside the conveying box 2.

[0023] The cotton scraping mechanism includes a scraper 91, the cross-section of which is set to be triangular. The narrower end of the scraper 91 is slidably connected to the top wall of the conveying box 2, and a movable plate 9 is fixed to the wider end of the scraper 91. The length of the scraper 91 is slightly smaller than the width of the internal opening of the conveying box 2, which facilitates the movement of the scraper 91 inside the conveying box 2. The two ends of the movable plate 9 are respectively fixed with cylindrical slide rods 92, and the slide rods 92 are slidably connected to the waist-shaped groove 22. The waist-shaped groove 22 is opened on the front and rear side walls of the conveying box 2. The waist-shaped groove 22 is set in a long strip shape, one end of the waist-shaped groove 22 does not extend to the feed port 21, and the other end of the waist-shaped groove 22 extends to the discharge port, which makes it easier for the scraper 91 to move to the top of the discharge port, so that the cleaned cotton wool falls into the discharge pipe 5. The slide rods 92 at both ends of the movable plate 9 are rotatably connected to the moving part.

[0024] The moving parts include a door frame-type driving plate 8, and the front and rear ends of the driving plate 8 are rotatably connected to the sliding rod 92 respectively. The sliding rod 92 located on the front side passes through the side wall of the driving plate 8, and the sliding rod 92 at this end is fixed with a rotating rod 93, and the rotating rod 93 is connected to the side wall of the driving plate 8 through a positioning piece. A gap is set between the two sides of the driving plate 8 and the conveying box 2, which facilitates the movement of the driving plate 8. The positioning piece includes a positioning hole clamped on the upper part of the rod body of the rotating rod 93, and the positioning hole extends to the side wall of the driving plate 8. A positioning pin 94 is installed in the positioning hole. The positioning pin 94 can fix the rotating rod 93 to the driving plate 8. When the narrow end of the scraper 91 contacts the top wall of the conveying box 2, the rotating rod 93 is just fixed to the driving plate 8 through the positioning pin 94.

[0025] The driving mechanism includes a driving motor 7 fixed to the upper end of the conveying box 2. The driving motor 7 is located on the conveying box 2 on the side away from the feed port 21. A threaded rod 71 is fixed to the rotating shaft at one end of the driving motor 7. One end of the threaded rod 71 is rotatably connected to the side wall of the feed port 21. The driving block 81 sleeved on the threaded rod 71 is fixed in the middle position of the upper end of the driving plate 8.

[0026] Working principle: When in use, the staff starts the driving motor 7 through the control device. The driving motor 7 is a servo motor. The driving motor 7 drives the threaded rod 71 to rotate, and the threaded rod 71 drives the driving plate 8 to move. The driving plate 8 drives the rod slide bar 92 to slide in the waist-shaped groove 22, and the slide bar 92 drives the moving plate 9 and the scraper 91 to move. The scraper 91 scrapes the cotton wool on the top wall of the conveyor box 2 onto the conveyor belt 31. If there is cotton wool accumulated on the scraper 91, the staff can pull out the positioning pin 94 at this time, and then rotate the rotating rod 93. The rotating rod 93 drives the slide bar 92 to rotate, and the slide bar 92 drives the scraper 91 to flip downward. After that, the cotton wool remaining on the scraper 91 can be cleaned onto the conveyor belt 31.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
