Device for opening and cleaning cotton waste

The innovation relates to a device for opening and Cleaning of cotton waste, especially strips, Card flying, battery waste, noils, filter waste and undercard waste having a fibrous material feed device for feeding the fibrous material to a opening roller and with a grate, which is located in the direction of rotation of the opening roller behind the feed device and a downstream fiber material collecting container.

Such a device is known from DE-AS 27 55 380.

The task of the innovation is to improve such a device that the degree of opening and Cleaning is increased significantly.

This object is achieved by the characterizing features of claim 1.

The innovation is based on the idea of keeping a dosed amount of waste material in a tightly dimensioned club room with the help of a beater roller as long as a

large-sized grate surface to lead until a predetermined Pre-cleaning has been achieved. Other work organs such as guide plates, blow bars, worker rollers, ejector knives, Wipers or the like are unnecessary. The fiber flake material is thereby gently opened up and cleaned. The grate is arranged eccentrically to the beater roller. The space between the impact roller and the housing is dimensioned very closely and designed so that it pulsates the fiber flake material with each revolution in and lets drift out of the tip circle of the beater roller, but the fiber flakes can only leave this for a very short time. In this way the fluff material becomes Conveys a high level of vehicle speed during the entire cleaning interval (two to five seconds), so that the fiber flocks, which are formed in alternating formation, are passed over the grate and through Centrifugal force continuously dedusted and cleaned. The only working organs are the grate and the beater roller are provided, the high cleaning effect of the invention Device in particular on the advantageous design of the racket space and the grate in Connection with the intermittent working method. The particular advantage is that the Waste material is pre-cleaned in such a way that it can then be removed with only one racket passage (e.g. a held Blow) can be cleaned out to such an extent that it is fed back into the blowroom line without contaminating the fresh cotton.

Further advantageous embodiments of the innovation emerge from the subclaims.

The innovation is explained in more detail below on the basis of exemplary embodiments shown in the drawings.

Fig. 1 shows a reserve shaft 1 (feed shaft), which the waste material from individual machines is fed to a blowroom. At the lower end of the reserve shaft 1 there are two opposite directions rotating take-off rollers 2 arranged, which the waste material of a downstream beater roller 3 feed (opening roller). The impact roller 3 runs at a peripheral speed of approximately 13 to 15 m / sec around. On the circumference of the beater roller 3, several strips 3a are arranged, which are equipped with round pins 3b (see Fig. 3). The beating drum 3 is tightly enclosed by a housing that partially consists of a grate 4 and a cover 5, e.g. B. a flap rotatable about a horizontal axis. The grate 4 is arranged eccentrically with respect to the beater roller 3, the distance between the beater roller 3 and the bars of the grate 4 in the direction of rotation of the beater roller
