[0008] As a further solution of the utility model: the driving assembly includes a driving motor, the driving motor is fixedly mounted on the outer wall of the box, the output end of the driving motor is fixedly connected to a rotating shaft, the rotating shaft passes through the box and rotates with the box, and an incomplete gear is fixedly connected to the outer side of the rotating shaft;

[0009] A complete gear is meshedly connected below the incomplete gear.

[0010] As a further solution of the utility model: a reset assembly is arranged inside the complete gear, and the reset assembly includes a sleeve, the sleeve is coaxially arranged with the filter screen, the sleeve is fixed to the cleaning roller, the sleeve is rotatably connected to the inside of the complete gear, and a support rod is connected to the sleeve through a clockwork spring, and the support rod is fixedly connected to the inner wall of the box.

[0011] As a further solution of the utility model: the rotating shaft is fixedly connected to the opening roller, and the number of the opening roller, the driving motor and the rotating shaft is set to two.

[0012] As a further solution of the utility model: the bottom of the box body is fully opened for unloading impurities.

[0013] As a further solution of the utility model: an adsorption pipe is provided on the top of the box body, and one end of the adsorption pipe is connected to a suction pump.

[0014] As a further solution of the utility model: the cleaning roller is in contact with the inner surface of the filter screen.

[0022] like Figures 1 to 4As shown, a refined cotton opening and impurity removal device comprises a box body 1, a conveying device 2 for conveying refined cotton located at one side of the box body 1, an opening roller 4 is arranged on one side of the box body 1 close to the conveying device 2, a filter screen 6 is arranged below the opening roller 4, the filter screen 6 is fixedly mounted on the inner wall of the box body 1, the filter screen 6 is arranged to have a semicircular opening, a cleaning roller 7 for cleaning impurities is arranged on the inner surface of the filter screen 6, and the cleaning roller 7 is arranged coaxially with the filter screen 6;

[0023] One end of the cleaning roller 7 away from the filter screen 6 is provided with a driving assembly.

[0024] The driving assembly includes a driving motor 5, which is fixedly mounted on the outer wall of the box body 1. The output end of the driving motor 5 is fixedly connected to a rotating shaft, which passes through the box body 1 and rotates with the box body 1. An incomplete gear 8 is fixedly connected to the outer side of the rotating shaft.

[0025] A complete gear 9 is meshedly connected below the incomplete gear 8 .

[0026] A reset assembly is arranged inside the complete gear 9, and the reset assembly includes a sleeve. The sleeve is arranged coaxially with the filter screen 6, the sleeve is fixed to the cleaning roller 7, the sleeve is rotatably connected to the inside of the complete gear 9, and a support rod 11 is connected to the sleeve through a clockwork spring 10, and the support rod 11 is fixedly connected to the inner wall of the box body 1.

[0027] The rotating shaft is fixedly connected to the opening roller 4, and the number of the opening roller 4, the driving motor 5 and the rotating shaft are all set to two.

[0028] The bottom of the box body 1 is fully open for unloading impurities.

[0029] An adsorption pipe is provided on the top of the box body 1 , and one end of the adsorption pipe is connected to a suction pump 3 .

[0030] During the specific operation, the refined cotton that needs to be cleaned is evenly placed on the upper surface of the conveying device 2 in advance, and the conveying device is used to convey the refined cotton to the position of the opening roller 4 for loosening. The refined cotton impurities after loosening fall along the filter screen 6, and the driving motor 5 drives the opening roller 4 to rotate while driving the incomplete gear 8 to rotate, and the rotation of the incomplete gear 8 drives the complete gear 9, and the rotation of the complete gear 9 drives the sleeve to rotate, and the sleeve overcomes the force of the spring spring 10 to rotate and drive the cleaning roller 7 to rotate. Since the cleaning roller 7 is in contact with the inner surface of the filter screen 6, the impurities remaining on the surface of the filter screen 6 can be quickly dropped when the cleaning roller 7 rotates, and discharged along the full opening of the box body 1. At the same time, the refined cotton that is not completely cleaned is flipped onto the opening roller 4 through the cleaning roller 7, and the refined cotton is cleaned again to avoid the waste of refined cotton caused by incomplete cleansing of the refined cotton.

[0031] When the incomplete gear 8 rotates to disengage the incomplete gear 8 from the complete gear 9, the sleeve moves in the opposite direction under the force of the clockwork spring 10, so that the sleeve is reset. When the sleeve is reset, the cleaning roller 7 is reset at the same time. When the incomplete gear 8 is meshed with the complete gear 9 again, the cleaning roller 7 can be driven to rotate again.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
