[0026] The present application provides an external circulation feeding box suitable for high-yield carding and blowing process. The present application combines the experience of long-term solving the problems of poor feeding of the feeding box and the disadvantages of internal circulation. The diameter of the feeding roller 2 and the opening roller 3 is unchanged, and the structure of the feeding roller 2 and the opening roller 3 is unchanged. On the basis of adopting the double-sided air exhaust of the stainless steel needle, through continuous exploration, test and innovation, the unique external circulation air exhaust feeding box is finally designed.

[0027] As Figs. 1-2As shown, the application specifically discloses a cotton feeding plate 1, a cotton feeding roller 2, an opening roller 3, a diffusion box 4, a front static pressure box 5, a rear static pressure box 6, a small fan 7 and a stainless steel carding plate 8. The opening roller 3 is located directly below and almost tangential to the cotton feeding roller 2. This arrangement can reduce the residence time of fibers on the opening roller cylinder and greatly shorten the running track, thereby greatly reducing the probability of winding the opening roller. The diffusion box 4 is arranged near the cotton feeding roller 2 and is connected to the air outlet of the small fan 7 through an air inlet pipeline. The air outlet direction of the diffusion box 4 is parallel to the common tangent of the cotton feeding roller 2 and the opening roller 3, which can simultaneously blow the fibers off the cotton feeding roller 2 and the opening roller 3, thereby reducing the probability of fiber winding the roller and / or the opening roller. The front static pressure box 5 and the rear static pressure box 6 are symmetrically arranged on the front and rear sides near the bottom of the overfeed channel 13 of the doffer, and the front static pressure box 5 and the rear static pressure box 6 are respectively provided with a stainless steel carding plate 8 on the panel facing the overfeed channel 13, and the left side of the front static pressure box 5 and the left side of the rear static pressure box 6 are respectively connected to the main dust removal pipeline 10 of the carding machine through the connecting pipe 11.

[0028] To ensure the tightness and compactness of the output lap, the adjustment range of the overfeed channel 13 formed by the front static pressure box 5 and the rear static pressure box 6 is optimized. Specifically, the front and rear widths of the overfeed channel 13 are adjusted from 80-120mm to 50-90mm, the front and rear widths are 50mm when the raw material is cotton, the front and rear widths are 90mm when the raw material is chemical fiber, and different widths are selected according to the characteristics of other raw materials.

[0029] The structure of the cotton feeding plate 1 and the cotton feeding roller 2 ensures the uniformity and smoothness of the cotton feeding of the cotton feeding roller 2, reduces the probability of fiber winding accidents, the double-sided exhaust of the doffer ensures sufficient exhaust volume and uniformity of the falling cotton, the front and rear static pressure boxes 6 provided with the stainless steel carding plate 8 ensure the uniformity and stability of the falling cotton of the doffer, the front and rear static pressure boxes 6 are connected to the main dust removal pipeline of the carding machine to ensure that the short fibers and impurities are smoothly sucked away. The air inlet of the small fan 7 is a natural air supplement, which is no longer directly connected to the stainless steel carding exhaust area of the rear static pressure box 6, thereby avoiding the interference of the small fan 7 on the uniform falling of the cotton and reducing the phenomenon of needle plate paste and flower. The air inlet pipeline and the diffusion box 4 designed through airflow running simulation and analysis calculation ensure that there is no dead angle and vortex, and the airflow in the exhaust channel is smooth.

[0030] In the embodiment of the application, the right side of the front static pressure box 5 and the right side of the rear static pressure box 6 are respectively provided with an adjustable air supplement structure.

[0031] In the embodiment of the present application, the air supplementing structure comprises an air volume adjusting plate 12, by adjusting the air volume adjusting plate 12 to shield the air supplementing opening of the front and rear static pressure boxes 6, the air supplementing volume can be conveniently adjusted according to the process requirement.

[0032] In the embodiment of the present application, the bottom of the rear static pressure box 6 is designed with an inclined arc surface, which conforms to the parabolic principle of fluid mechanics, and ensures that the impurities always fall in the area that can be sucked by the airflow.

[0033] The fibers falling from the upper cotton box are gripped and opened by the lapping plate 1, the lapping roller 2 and the opening roller 3, and then blown evenly to the lower cotton box by the air diffused by the diffusion box 4, and the air is discharged from the gap between the front and rear stainless steel carding plates 8, and the fibers are evenly dropped into the lower cotton box. This air discharge structure of the stainless steel carding plate 8 not only solves the problems of linting and deformation caused by the early sheet metal powder spraying parts, but also makes the uniformity and compactness of the fibers reach an ideal state. The part of the short fibers and impurities carried out by the air when it is discharged from the front and rear carding plates are connected to the main dust filtering pipeline 10 of the carding machine through the left connecting pipe 11, and the discharged short fibers and impurities are also sucked away at the same time. The air volume adjusting plate 12 on the right side can adjust the size of the air supplementing volume according to the accumulation of the short fibers and impurities in the front and rear static pressure boxes 5 and 6, so as to ensure that the discharged short fibers and impurities can be sucked away. The air blown into the lower cotton box is discharged through the air return pipeline 9.

[0034] The above description is only the optional embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields based on the inventive concept of the present application and the content of the specification and drawings are included in the patent protection scope of the present application.
