Description of drawings
Accompanying drawing is a specific embodiment structure chart of the present invention.
The specific embodiment
Ask for an interview accompanying drawing, end in frame 1 promptly is provided with suction hood 4 by the right-hand member of current icon location status, and the lower edge of suction hood 4 is hinged by articulated elements 41 and suction hood support 42, and suction hood support 42 is fixed on the frame 1, in the present embodiment, select hinge to fill the post of articulated elements 41.Also be provided with suction port 43 on suction hood 4, suction port 43 is corresponding to the following down scavenge unit 5 that also will describe in detail, and suction port 43 is by source of the gas pipeline and depression generator negative-pressure air fan pipeline connection for example.In the corresponding both sides of an end of aforesaid frame 1, promptly the left-hand portion of suction hood support 42 respectively is provided with an axle bed 11, and a pair of axle bed 11 corresponds to each other.
The quantity of one group of drawing rollers 2 is three (not illustrated the restriction of quantity), the two ends of each drawing rollers 2 respectively are furnished with a roller axle bed 21, each roller axle bed 21 is fixed on the frame 1, and each drawing rollers 2 connects by the actuating unit transmission of power transmission shaft 22 with drawing frame.The quantity of one group of pressure roller 3 equates with drawing rollers 2, corresponds respectively to the top of corresponding drawing rollers 2, more particularly, and a pressure roller 3 and drawing rollers 2 shared a pair of roller axle beds 21.Respectively extended a positioning seat 12 on a pair of roller axle bed 21 that corresponds to each other of left end, a pair of positioning seat hole 12 is corresponding mutually, is used for hanging for down scavenge unit 5.
The structure of preferred down scavenge unit 5 is as follows: an end of first, second support 51,52 is respectively to be installed with support shaft 513 on the outer wall of illustrated right-hand member, in the axis hole 111 of pair of brackets axle 513 hub settings on a pair of axle bed 11, the other end of a pair of first, second support 51,52 be illustrated left end be installed with respectively first, second the hook 511,521, first, second the hook 511,521 with a pair of positioning seat 12 mutually hook join.Be installed with one first location-plate 512 at first support 51 towards a side of second support 52, and be installed with one second location-plate 522 towards a side of first support 51 at second support 52, and, first, second location-plate 512,522 is stuck in first, second support 51,52 respectively, and what the two ends of deflector roll 54 were rotatably supported in first, second location-plate 512,522 leans out the position, end.The two ends of drive roll 53 hub setting respectively (being provided with rotationally) is at the right-hand member of first, second support 51,52, and drive roll 53 is connect by the transmission mechanism transmission of its transmission shaft 531 with drawing frame.Pressure roller 55 is between drive roll 53 and deflector roll 54, and hub setting is on first, second support 51,52.Cleaning curtain 56 is nested with on drive roll 53 and deflector roll 54, and contacts with one group of pressure roller 3, and pressure roller 55 contacts with the lower plane of cleaning curtain 56.The material of preferred cleaning curtain 56 is a cloth matter.
Pass through between one group of pressure roller 3 and drawing rollers 2 by the also strip device of drawing frame and sliver 6 right-to-lefts (is example with illustrated location status) after the system, by 2 pairs of sliver 6 drawing-offs of drawing rollers, the suction hood 4 of this moment is fastened on the down scavenge unit 5, and, down scavenge unit 5 is fastened on one group of pressure roller 3, specifically: a pair of first, second hook 511,521 hooks are put on a pair of positioning seat 12, so that cleaning curtain 56 is contacted with pressure roller 3.In the drafting process to sliver 6, down adheres on one group of pressure roller 3 of rubber mass by means of electrostatic effect, and then is transferred to (being driven by drive roll 53) the cleaning curtain 56 that is kept in motion.Because what cleaning curtain 56 formed is that phoresying of going round and beginning again is cleaned the plane, therefore the down fiber that is transferred on the cleaning curtain 56 by 43 pairs of suction ports is absorbed, and pressure roller 3 is maintained in the clean condition.Sliver 6 after drawing-off is for the subsequent handling resultant yarn.
