Abstract

The invention discloses a fluff pulse airflow sorting device which comprises a frame, a rolling shaft, a reducing motor, an air source, a heavy material box and a light material box, wherein the rolling shaft is arranged on the frame; a rolling shaft, a heavy material box and a light material box are sequentially arranged on the frame from one side to the other side; the rolling shaft is arranged at the top of the frame; an upper blowing pipe with an upward air outlet is arranged below the discharge hole of the roller; a hollow arc-shaped shielding fan cover is arranged above the rolling shaft, and lower air blowing holes communicated with the inner cavity of the arc-shaped shielding fan cover are uniformly distributed on the bottom surface of the arc-shaped shielding fan cover above the discharge hole of the rolling shaft; the inner cavities of the upper blowing pipe and the arc-shaped shielding hood are respectively communicated with an air source through pipelines, and pulse valves are arranged on the pipelines between the air source and the upper blowing pipe. The beneficial effects are that: the short fiber and the wool are blown up by using the pulse air flow, and fall into different intervals according to the different weights of the short fiber and the wool, so that the secondary damage of the short fiber is reduced, and the extraction efficiency of the short fiber is improved.

Description

Fluff pulse airflow sorting device

Technical field:

the invention relates to a sorting device, in particular to a fluff pulse airflow sorting device.

The background technology is as follows:

fluff mixed leftovers generated during carding links of animal fiber products such as fluff, fluff and the like, wherein the fluff mixed leftovers contain utilizable short fluff fibers; in the prior art, carding is adopted for sorting, so that the extraction effect is poor, the short staple fibers are damaged again and cannot be used, and the short staple fibers are wasted.

The invention comprises the following steps:

the invention aims to provide a fluff pulse airflow sorting device which reduces the secondary damage of short fibers and improves the extraction efficiency of the short fibers.

The invention is implemented by the following technical scheme: a fluff pulse airflow sorting device comprises a frame, a rolling shaft, a gear motor, an air source, a heavy material box and a light material box; the rolling shafts, the heavy material box and the light material box are sequentially arranged on the frame from one side to the other side; the rolling shaft is arranged at the top of the frame; the speed reducing motor is arranged below the rolling shaft and is in transmission connection with the rolling shaft through a chain; an upper blowing pipe with an upward air outlet is arranged below the discharge hole of the roller; a hollow arc-shaped wind shielding cover is arranged above the rolling shaft, and lower wind blowing holes communicated with the inner cavity of the arc-shaped wind shielding cover are uniformly distributed on the bottom surface of the arc-shaped wind shielding cover above the discharge hole of the rolling shaft; the inner cavities of the upper blowing pipe and the arc-shaped shielding hood are respectively communicated with the air source through pipelines, and pulse valves are arranged on the pipelines between the air source and the upper blowing pipe; and a guide plate which is inclined upwards towards the heavy material box is fixedly arranged above the arc-shaped shielding fan cover.

Further, knurling is arranged on the outer circular surface of the roller.

The invention has the advantages that: the short fiber and the wool are blown up by using the pulse air flow, and fall into different intervals according to the different weights of the short fiber and the wool, so that the secondary damage of the short fiber is reduced, and the extraction efficiency of the short fiber is improved.

Description of the drawings:

FIG. 1 is a schematic diagram of the overall structure of the present invention;

FIG. 2 is a schematic view of section A-A of FIG. 1.

FIG. 3 is a schematic view of section B-B of FIG. 1.

Fig. 4 is an enlarged partial schematic view of portion C of fig. 1.

The device comprises a frame 1, a roller 2, a gear motor 3, an air source 4, a heavy material box 5, a light material box 6, an upper blowing pipe 7, an arc-shaped shielding fan cover 8, a lower blowing hole 8.1, a pulse valve 9, a guide plate 10, knurling 11 and a blanking plate 12.

The specific embodiment is as follows:

the invention will be described in further detail by way of examples with reference to the accompanying drawings.

The fluff pulse airflow sorting device comprises a frame 1, a rolling shaft 2, a gear motor 3, an air source 4, a heavy material box 5 and a light material box 6; a rolling shaft 2, a heavy material box 5 and a light material box 6 are sequentially arranged on the frame 1 from one side to the other side; the rolling shaft 2 is arranged at the top of the frame 1; a gear motor 3 is arranged below the roller 2, and the gear motor 3 is in transmission connection with the roller 2 through a chain; an upper blowing pipe 7 with an upward air outlet is arranged below the discharge hole of the roller 2, and the fluff is blown up by the air blown out by the upper blowing pipe 7; a hollow arc-shaped wind shield 8 is arranged above the roller 2, lower wind blowing holes 8.1 communicated with the inner cavity of the arc-shaped wind shield 8 are uniformly distributed on the bottom surface of the arc-shaped wind shield 8 above the discharge hole of the roller 2, air is introduced into the inner cavity of the arc-shaped wind shield 8 and blown out from the lower wind blowing holes 8.1, and fluff is prevented from being reeled into the roller 2 from above the discharge hole of the roller 2; the inner cavities of the upper blowing pipe 7 and the arc-shaped shielding hood 8 are respectively communicated with the air source 4 through pipelines, a pulse valve 9 is arranged on the pipeline between the air source 4 and the upper blowing pipe 7, and air is introduced into the upper blowing pipe 7 at certain intervals, so that fluff at the discharge port of the roller 2 is lifted; a guide plate 10 which is inclined upwards towards the heavy material box 5 is fixedly arranged above the arc-shaped wind shield 8 and plays a guiding role on fluff to redirect the blown fluff to fly towards the heavy material box 5; the outer circular surface of the roller 2 is provided with knurling 11, so that fluff can be brought to the discharge hole of the roller 2.

Working principle: the fine hair falls to the feed inlet of roller bearing 2 from blanking board 12, and the discharge gate of roller bearing 2 is carried to the fine hair of the feed inlet department of roller bearing 2 to rotatory roller bearing 2, and the strong pulse air current of blowing out from the last blowpipe 7 of roller bearing 2's discharge gate below blows up the fine hair, and the fine hair of blowing up runs into guide plate 10 and changes direction, and the fine hair is according to the light weight of self, makes it fall into different intervals, and the fine hair falls into heavy workbin 5 promptly, and the short staple fiber falls into light material box 6, has reduced the injury again of short staple fiber, has improved short staple's extraction efficiency.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
