[0010] Preferably, a guide sleeve is fixedly connected to the upper left side of the perforated plate, and a guide rod is slidably connected to the inner side of the guide sleeve. The top of the guide rod is fixedly connected to the connecting block on the left side. The guide sleeve and guide rod provide a guiding function for the lifting and lowering of the plug.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model generates negative pressure through an air pump, which can efficiently remove impurities and short fibers generated during the carding process. The electric push rod can control the lifting and lowering of the plug to achieve sealing of the dust collection cavity and rapid slag discharge. Moreover, the design of the guide sleeve and guide rod ensures the smoothness of the plug's movement and the reliability of the seal, avoiding gas backflow after sealing and preventing the backflowing air from blowing impurities back onto the cotton sliver.

[0012] 2. This utility model features a self-anti-clogging mechanism for impurity removal installed on the base.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 A carding device for cotton sliver processing includes a housing 1. A needle roller 2, a stripping roller 3, and an output roller 4 are arranged inside the housing 1. The stripping roller 3 and the output roller 4 are located on the left and right sides of the needle roller 2, respectively. A circulating belt 5 is arranged on the upper part of the inner side of the housing 1, which is located above the needle roller 2. A base 6 is fixedly connected to the bottom of the inner side of the housing 1, which is located below the needle roller 2, the stripping roller 3, and the output roller 4.

[0017] Please see Figures 3-5The base 6 is equipped with a self-anti-clogging mechanism 7 for removing impurities. The self-anti-clogging mechanism 7 includes a hollow cylinder 71 fixedly connected inside the base 6. An air pump 72 is fixedly installed on the bottom inner side of the housing 1. A connecting pipe 73 is fixedly connected to the input end of the air pump 72. The connecting pipe 73 passes through the housing 1 and the base 6 and enters the hollow cylinder 71. A conical tube 74 is fixedly connected to the inner side of the upper opening of the hollow cylinder 71. A filter screen 75 is in contact with the upper end of the conical tube 74. A rubber bead 76 is fixedly connected to the bottom of the filter screen 75. The rubber bead 76 is engaged with the conical tube 74. The rubber retaining beads 76 secure the filter screen 75. A protrusion 77 is fixedly connected to the bottom of the filter screen 75. A plug 78 is slidably connected to the inner side of the lower opening of the tapered tube 74. A rotating shaft 79 is mounted on the upper end of the plug 78 via a bearing. A fan blade 710 is fixedly connected to the shaft of the rotating shaft 79, and a striking rod 711 is fixedly connected to the shaft. A sliding sleeve 712 is fitted onto the outer side of the striking rod 711. The top of the sliding sleeve 712 abuts against the bottom of the filter screen 75, and the end of the sliding sleeve 712 corresponds to the position of the protrusion 77. The impurity removal and anti-clogging mechanism 7 facilitates the rapid discharge of impurities shaved off by the needle roller 2 while preventing clogging of the filter components themselves.

[0018] Please see Figures 4-5 The impact rod 711 has a ball bearing 713 mounted on its body, which is slidably connected to the inner wall of the sliding sleeve 712. The ball bearing 713 reduces the relative friction between the sliding sleeve 712 and the impact rod 711. A square rod 714 is fixedly connected to the top inner side of the sliding sleeve 712, and is slidably connected to the impact rod 711. A spring 715 is fitted onto the outer side of the square rod 714, with one end fixedly connected to the impact rod 711 and the other end fixedly connected to the inner surface of the sliding sleeve 712. The square rod 714 and spring 715 allow a reaction force to be applied to the sliding sleeve 712, ensuring that the sliding sleeve 712 remains in contact with the bottom of the filter screen 75. Connecting blocks 718 are fixedly connected to both sides of the plug 78. A perforated plate 716 is fixedly connected to the lower inner side of the hollow cylinder 71. An electric push rod 717 is fixedly installed on the upper right side of the perforated plate 716. The end of the telescopic shaft of the electric push rod 717 is fixedly connected to the right connecting block 718. Through the cooperation of the electric push rod 717 and the connecting blocks 718, the plug 78 can be opened and closed electrically. A guide sleeve 720 is fixedly connected to the upper left side of the perforated plate 716. A guide rod 719 is slidably connected to the inner side of the guide sleeve 720. The top of the guide rod 719 is fixedly connected to the left connecting block 718. Through the setting of the guide sleeve 720 and the guide rod 719, the plug 78 can be guided to rise and fall.

[0019] The specific implementation process of this utility model is as follows: When in use, the connecting block 718 is pulled down by the electric push rod 717. The connecting block 718 drives the plug 78 to move down and releases the lower end of the cone tube 74. Then the air pump 72 continues to work, generating negative pressure in the hollow cylinder 71. Impurities and short fibers generated in the area of ​​the needle roller 2 are adsorbed by the airflow and sucked into the filter screen 75 through the cone tube 74. Impurities are intercepted and accumulated by the filter screen 75, while air is drawn away through the filter screen 75 and the connecting pipe 73. When the airflow flows through the cone pipe 74 to the plug 78, it drives the fan blade 710 to rotate, thereby driving the rotating shaft 79 and the impact rod 711 to rotate. The rotating impact rod 711 and the sliding sleeve 712 periodically strike the protrusion 77 at the bottom of the filter screen 75. Since the sliding sleeve 712 is restricted from rotating by the square rod 714 and the spring 715, it can make a small axial sliding, so that the sliding sleeve 712 continuously knocks and vibrates the bottom of the filter screen 75, thereby effectively knocking away the fiber clumps and impurities attached to the filter screen 75 and preventing them from clogging the mesh.
