[0032] like Figure 5 As shown, in order to ensure the separation effect of the equipment and prevent fluff in the air flow from entering the external air pressure equipment along the pipeline, the dust collection and separation mechanism 2 also includes a dust reduction box 23, which is clamped inside the separation box 21, and an air delivery plate 231 is provided on one side of the dust reduction box 23, and the air delivery plate 231 is installed on one side of the transmission box 4.

A sedimentation liquid is provided inside the dust reduction box 23, and the one-way delivery pipe can also play an isolating role to prevent the sedimentation liquid from flowing back.

[0033] A fixed cover 25 is installed on the top of the dust suppression box 23, and the fixed cover 25 is used for sealing. A plurality of compression tubes 251 are installed at the bottom of the fixed cover 25, and a fixed frame 26 is installed at the bottom of the compression tube 251.

[0034] like Figure 6As shown, in order to reduce the situation where the overflowing sedimentation liquid contains efficient lint and debris, a plurality of buffer rods 27 are installed inside the fixed frame 26. The buffer rods 27 are rectangular and elastic. The buffer rods 27 are evenly arranged between the fixed frames 26. A plurality of reset balls 28 are clamped inside the buffer rods 27.

A through groove is provided on the top of the separation box 21, and a sealing plate 24 is provided inside the through groove. A plurality of transmission tubes 241 are installed on the sealing plate 24. The transmission tubes 241 are connected to the external air pressure equipment.

[0036] like Figure 3 As shown, in order to ensure the stability of carpet transmission, the auxiliary transmission mechanism 3 includes a clamping frame 31, a pair of welding plates are fixedly connected to the inner wall of the clamping frame 31, and a winding shaft 33 is rotatably provided between the welding plates. One end of the carpet can be clamped on the winding shaft 33. As the winding shaft 33 rotates, the carpet can be pulled and slowly transmitted inside the dust reduction box 1.

[0037] like Figure 4 As shown, in order to reduce the residue of debris and dust in the carpet, the outer walls of both ends of the clamping frame 31 are clamped with slide rail grooves 32, and the slide rail grooves 32 are movably clamped with slide plates 34, and the slide plates 34 are installed inside. Positioning plates 35 are installed inside, and positioning rings 36 are installed inside the positioning plates 35. A slot is opened on the inner wall of the positioning ring 36, and a reset rod 361 is inserted inside the slot. The reset rod 361 is evenly arranged in an array inside the positioning ring 36;

[0038] A rotating disk 37 is rotatably provided on the inner wall of the positioning disk 35, and movable rods 371 are inserted on the side walls of the rotating disks 37 at both ends. A plurality of connecting rings 38 are clamped on the movable rods 371, and the connecting rings 38 are elastic. The movable rods 371 can be squeezed with the bottom of the reset rods 361 during transmission. The rotation of the rotating disk 37 can make the movable rods 371 squeeze between the reset rods 361 during the circular motion, so that the movable rods 371 can make reciprocating motion during the transmission process, and the suede surface of the carpet can be continuously slapped and cleaned, and the dust and debris accumulated inside can be quickly shaken off, and the dust can be quickly discharged with the help of airflow to avoid secondary adsorption on the carpet.

[0039] like Figure 7 As shown, dust piles are prone to accumulate quickly after long-term operation. A card slot is provided on the side of the transmission box 4 close to the dust suction and separation mechanism 2, and the position of the card slot corresponds to the air transmission plate 231. A rectangular frame 41 is provided on the inner wall of the transmission box 4, and an elastic screen plate 42 is installed inside the rectangular frame 41. The cross-section of the elastic screen plate 42 is wavy, and a plurality of counterweight shafts 43 are fixedly connected to the elastic screen plate 42. A plurality of annular grooves are provided on the counterweight shaft 43, and an elastic sheet is provided inside the annular groove. Under the action of airflow, the elastic sheet can swing under the action of airflow, thereby driving the elastic screen plate 42 to swing. The elastic screen plate 42 can squeeze and shake off the dust and impurities adsorbed on the surface of the air guide, so as to prevent blockage during the air guide transmission process.

[0040] Preferably, a transmission groove is opened on the surface of the dust reduction box 1, and a positioning plate 11 is provided at the bottom of the transmission groove, a pair of vertical plates are installed on the positioning plate 11, and a transmission rod is rotatably provided between the vertical plates, and clamping shafts 12 are installed on the side walls at both ends of the dust reduction box 1, and a transmission roller 14 is provided between the clamping shafts 12. The transmission roller 14 penetrates the side wall of the dust reduction box 1 and is rotatably set between the clamping shafts 12. Under the cooperation of the transmission roller 14 and the clamping shaft 12, the transmission position of the carpet can be limited to ensure smooth transmission of the equipment, and it can also be away from the location of subsequent dust cleaning to reduce the situation of secondary adsorption of a large amount of dust.

[0041] Working principle: first, when the carpet needs to be transported and rolled up, one end of the carpet can be clamped on the winding shaft 33, and the rotation of the winding shaft 33 can drive the carpet to be transported inside the dust reduction box 1. With the help of the auxiliary transmission mechanism 3, the carpet can be stretched and cleaned. Under the action of the external air pressure device, the dust inside the dust reduction box 1 can be conducted along the transmission box 4 and the dust suction and separation mechanism 2, and discharged under the action of negative pressure, and the dust suction and separation mechanism 2 can filter and clean the dust and debris. During the carpet transmission process, it can be positioned under the action of the rotating roller and the transmission roller 14, and wound before the winding shaft 33. With the action of the movable plug rod 371 and the connecting ring 38, it can contact the suede surface of the carpet, and play the role of cleaning and combing the suede during the transmission process. As the movable plug rod 371 moves in a circular motion, it can squeeze the reset plug rods 361, so that the movable plug rod 371 can reciprocate during the transmission process, and the suede surface of the carpet can be continuously slapped and cleaned, and the dust and debris accumulated inside can be quickly shaken off.

[0042] Then, under the action of the external air pressure device, the dust inside the dust reduction box 1 can be quickly discharged along the transmission box 4 and the dust collection and separation mechanism 2, and under the action of the airflow, the elastic sheet can swing under the action of the airflow, thereby driving the elastic screen plate 42 to swing, and preventing blockage during the diversion transmission process;

[0043] Finally, after the airflow enters the dust removal box 23, the internal hair and debris can be quickly separated under the action of the sedimentation liquid, which can play a role in screening. In the separation process, the bottom sedimentation liquid flows under the action of the airflow. When some sedimentation liquid and hair pass through the mesh screen plate 29, the adsorption plate 281 on the outer wall of the reset ball 28 can be used to collect and adsorb the excess hair in the sedimentation liquid, so as to prevent it from entering the connecting pipe of the external air pressure equipment along the airflow.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
