[0015] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] The technical solution specifically implemented in the present invention is: In a specific embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the present invention provides a feeding roller mechanism for finishing knitted cotton fabrics, comprising a shell 1 and two conveying rollers 2 arranged inside the shell 1, wherein a fabric inlet 3 and a fabric outlet 4 are respectively provided at both ends of the shell 1, and the two conveying rollers 2 clamp and convey the fabric 100; two groups of cleaning components are provided inside the shell 1, and the two groups of cleaning components correspond one-to-one to the two conveying rollers 2 and are respectively located on the upper and lower sides of the fabric 100, along the conveying direction of the fabric 100, the cleaning components are located upstream of the corresponding conveying rollers 2, and the cleaning components include a dust collection bin 5, a dust collecting bin 6 and a transmission shaft 7, a negative pressure chamber 8 is provided inside the dust collection bin 5, and the dust collection bin 5 is provided with an air inlet 9 connected with the negative pressure chamber 8 and facing the fabric 100, an air inlet one-way valve 10 is provided in the air inlet 9, and the air inlet one-way valve 10 is unidirectionally conducted from the outside to the negative pressure chamber 8, and the negative pressure chamber A conducting pipe 11 is connected between 8 and the dust collecting bin 6, and an air outlet one-way valve 12 is provided at the connection between the conducting pipe 11 and the negative pressure chamber 8. The air outlet one-way valve 12 is unidirectionally guided by the negative pressure chamber 8 to the conducting pipe 11, and a piston plate 13 is sealingly and slidingly connected in the negative pressure chamber 8, and the piston plate 13 is connected to the piston rod 14, and the piston rod 14 extends to the outside of the dust collection bin 5, and one end of the transmission shaft 6 is connected to a turntable 15, and a connecting rod 16 is provided between the turntable 15 and the piston rod 14, and the two ends of the connecting rod 16 are hinged to the piston rod 14 and the edge of the turntable 15 respectively through an axle pin, and the other end of the transmission shaft 7 extends to the outside of the shell 1 and is connected to a second pulley 17, and one end of the roller shaft of the conveying roller 2 extends to the outside of the shell 1 and is connected to a first pulley 18, and a transmission belt 19 is connected between the first pulley 18 and the second pulley 17.

[0017] Adopting the above scheme: the working principle of the feeding roller mechanism for finishing knitted cotton fabrics of the present invention is as follows: When in use, the two conveyor rollers 2 are driven to rotate in opposite directions respectively, and the fabric 100 is clamped and conveyed by the two conveyor rollers 2. At the same time, the roller shaft of the conveyor roller 2 drives the transmission shaft 7 and the turntable 15 to rotate through the first pulley 18, the transmission belt 19 and the second pulley 17, so that the turntable 15 drives the piston plate 13 in the negative pressure chamber 8 to reciprocate through the connecting rod 16 and the piston rod 14. When the piston plate 13 moves in the direction away from the air inlet 9, the air inlet check valve 10 is in the open state and the air outlet check valve 12 is in the closed state, so that the negative pressure A negative pressure state is formed inside the cavity 8, thereby generating suction at the air inlet 9, and sucking the thread ends, dust and processing residues attached to the surface of the fabric 100 into the negative pressure cavity 8 through the air inlet 9. When the piston plate 13 moves toward the air inlet 9, the air inlet check valve 10 is in a closed state and the air outlet check valve 12 is in an open state. At this time, the piston plate 13 discharges the dust-laden gas in the negative pressure cavity 8 through the conducting pipe 11 to the dust collecting bin 6.

[0023] The above solution is adopted to achieve fixed installation of the dust suction bin 5 and the dust collection bin 6 .

[0024] In another specific embodiment, Figure 1 As shown, the cleaning assembly also includes a brush roller 20, which is located between the dust collection bin 5 and the conveying roller 2, and one end of the roller shaft of the brush roller 20 extends to the outside of the shell 1 and is connected to a second gear 21, and the roller shaft of the conveying roller 2 is connected to a first gear 22 that meshes with the second gear 21.
