[0039] As shown in Figure 2 The suction structure 200 comprises: a plurality of suction units 210, and a connecting rod structure 220 arranged between adjacent suction units 210; the rotating shaft 110 is horizontally arranged, the plurality of suction units 210 are respectively hingedly connected with the rotating shaft 110, the rotating shaft 110 is provided with one ratchet structure 300 at each end along the axis, and each suction unit 210 is respectively provided with one electrostatic generator. Among them, the suction unit 210 has a sensitive property, can receive static electricity generated on the electrostatic generator, and can use static electricity to adsorb and clean the fibers floating in the air.

[0040] As shown in Figure 3As shown, each ratchet structure 300 comprises: a ratchet disc 310, and a pawl 320 connected with the ratchet disc 310; each ratchet disc 310 is fixedly connected with one adsorption unit 210 respectively, and each pawl 320 is arranged on the rotating shaft 110, and the gear directions of the adjacent ratchet discs 310 are opposite. The connecting rod structure 220 is used for limiting and driving the several adsorption units 210 to rotate reversely and with the same amplitude.

[0041] When the rotating shaft 110 rotates in one direction, the pawl 320 arranged on one end of the rotating shaft 110 is clamped with the ratchet disc 310 and drives the ratchet disc 310 to rotate, and the pawl 320 arranged on the other end of the rotating shaft 110 cannot be clamped with the corresponding ratchet disc 310 but rotates along the ratchet disc 310.

[0046] The servo motor 120 controls the forward and reverse rotation of the rotating shaft 110, which can drive the adsorption unit 210 to rotate through the forward and reverse rotation of the rotating shaft 110, so that the upper part and the lower part of the adsorption unit 210 stagger to open and close, the servo motor 120 can control the amplitude, speed and direction of the rotating shaft 110 to control the position and efficiency of the rotation of the adsorption unit 210, and the adsorption degree of the airflow fibers can be accurately controlled.

[0047] The rotation shaft 110, the electrostatic generator, the adsorption unit 210 and the ratchet structure 300 are used to swing the adsorption unit 210 and make the adsorption unit 210 carry static electricity, and the adsorption unit 210 can adsorb the fibers in the swing, so that the fibers are adsorbed onto the adsorption unit 210 under the joint action of electrostatic attraction and air flow, the adsorption capacity of the fibers is enhanced, the content of the fibers in the air is reduced, the influence of the fibers in the air on the laying process is avoided, and the defect that the adsorption range of the laying cleaning structure in the prior art is small is solved.

[0048] The connecting rod structure 220 comprises a plurality of branch rods 221, a vertical rod 222 hingedly connected with the plurality of branch rods 221, and a sleeve 223 sleeved with the vertical rod 222; and the sleeve 223 is fixedly connected with the rack 100.

[0049] The number of the plurality of branch rods 221 is consistent with the number of the adsorption units 210, and each branch rod 221 is hingedly connected with an adsorption unit 210. The plurality of branch rods 221, the vertical rod 222 and the sleeve 223 are arranged on the same vertical plane, the vertical rod 222 and the sleeve 223 are coaxially arranged and vertically arranged, and the vertical rod 222, the sleeve 223 and the rotation shaft 110 are located on the same vertical plane.

[0050] When one branch rod 221 is driven to rotate, the vertical rod 222 is driven to move vertically, and the other branch rod 221 is driven to rotate in the opposite direction, and the two branch rods 221 are consistent in length and symmetrical about the vertical plane where the rotation shaft 110 is located, so that the rotation amplitudes of the branch rods 221 are consistent.

[0051] Each adsorption unit 210 is provided with a plurality of adsorption teeth for increasing the contact surface of the adsorption unit 210. The plurality of adsorption teeth are detachably connected with the adsorption unit 210, and the adaptability to various cleaning devices can be improved by changing the shape and length of the adsorption teeth. Each adsorption unit 210 is provided with an adsorption plate located above the plurality of adsorption teeth. Adjacent adsorption teeth and adjacent adsorption plates are respectively symmetrically distributed about the vertical plane where the rotation shaft 110 is located.

[0052] The adsorption plate and the adsorption teeth are respectively located on the upper part and the lower part of the adsorption unit 210, the adsorption plate located on the upper part of the adsorption unit 210 is opened away when the adsorption teeth of adjacent adsorption units 210 rotate towards each other, and the adsorption teeth located on the lower part of the adsorption unit 210 are opened away when the adsorption plates of adjacent adsorption units 210 rotate towards each other, so that the resources can be effectively utilized and the resource utilization rate is improved.

[0053] The arrangement of the adsorption plate and the adsorption tooth increases the contact area between the adsorption unit 210 and the air, so that the adsorption unit 210 can more fully contact the fibers in the air, and the adsorption tooth can more conveniently contact the cleaning device, so that the removal of the fibers on the adsorption tooth is accelerated, the fiber removal capacity is improved, and the fiber removal efficiency is increased.

[0054] In the present application, the fibers above the adsorption plate and below the adsorption tooth are attracted with the rotation of the adsorption plate and the adsorption tooth, and the leather curtain is located between the cleaning device and the fibers, so that the fibers are attached to the leather curtain, and the generation of the fibers in the air is reduced.

[0056] S1: the servo motor 120 drives the rotating shaft 110 to rotate;

[0057] S2: in S1, one pawl 320 on the rotating shaft 110 drives the corresponding ratchet disc 310 to rotate, and the adsorption unit 210 on the ratchet disc 310 rotates with the rotating shaft 110;

[0058] S3: in S2, the electrostatic generator makes the rotating adsorption unit 210 carry static electricity, and the fibers in the air are adsorbed; the forward and reverse rotation of the rotating shaft 110 respectively drives the rotation of the plurality of ratchet discs 310, so that the adsorption unit 210 rotates forward and reversely.

[0059] S4: in S3, after the adsorption unit 210 adsorbs the fibers, the cleaning device cleans the fibers on the adsorption unit 210.

[0060] In S3, the adsorption unit 210 carries static electricity and rotates around the rotating shaft 110, so that the fibers around the adsorption unit 210 are attached to the adsorption unit 210 by electrostatic adsorption or air flow. When the adsorption unit 210 cooperates with the cleaning device, the electrostatic generator stops delivering static electricity, the fibers attached to the adsorption unit 210 fall into the cleaning device under the disappearance of static electricity and the scraping of the cleaning device, and the removal of the fibers is completed.

[0061] After the adsorption unit 210 adsorbs the fibers in the air, the angle can be adjusted to match the cleaning device, compared with the prior art, the number of cleaning devices can be increased and the position of the cleaning device can be adjusted, the adaptability of the adsorption unit 210 and the cleaning device can be effectively improved, and the applicability of the adsorption unit 210 to various paving structures can be enhanced.
