Definitions
- the material supply of the card has an influence on the end product of the card: the card sliver. Irregularities in the feed can be found in the tape, since they are responsible for the formation of thick or thin spots, c. q. cause the formation of thick or thin spots. These defects can hardly be corrected in the course of the remaining processes to produce a yarn and therefore have a direct influence on the final yarn quality.
- the wadding that is formed in the feed shaft must be equally distributed across the width and of the same density.
- One problem is the pneumatic flake feed, which feeds the individual card with flakes unevenly. This problem was solved by means of a shaft which was closed by a
- Feeding device was divided into two parts, so that the actual cotton wool to the card is only locally influenced by this feeding device.
- the shafts have been optimized with an improvement in the air balance and constructive improvements, it is
- BESTATIGUNGSKOPIE mainly the cleaning machines, such as coarse cleaners or fine cleaners, are responsible.
- the coarse cleaner is usually arranged at the beginning of the process directly after the bale opener, which removes the cotton from the bale and feeds it into the pneumatic transport.
- the coarse cleaner is available in very different models, but they have some common features.
- the material is mostly processed in free flight using roughly equipped work rolls. The opening effect is therefore low and, above all, coarse dirt that is present on the outside of the flakes is removed.
- Coarse cleaners also remove free dirt particles, such as shell parts or other foreign bodies.
- the fine cleaner comes much later in the process and is usually immediately upstream of the cards.
- the fine cleaner is more aimed at removing dirt from inside the flakes. This cleaning step should therefore take place after an additional opening step.
- the fine cleaner almost always works with a clamped feed and a finer assembly of the roller downstream of the feed.
- the opening roller is equipped as a cleaning roller, for example with rust knives and a saw tooth set on the roller.
- the range from 10 to a maximum of 190 ° with respect to the vertical line through the axis of rotation of the opening roller in the direction of rotation is preferably suitable for the arrangement of a discharge point.
- the two discharge points are preferably arranged in such a way that trouble-free waste disposal is ensured and any impairments to the air balance are excluded.
- the dirt discharge point hereinafter referred to as the separation point, is defined by the separation gap between the transfer point and the knife edge.
- the transfer point is defined as the point where the smallest distance between the set of the feeding device and that of the opening roller is. This point is sometimes called the point of combing, here the fibers are taken over by the opening roller.
- the distance between the transfer point and the knife edge expressed in the angle ( ⁇ ) between the transfer point and the knife edge, measured from the transfer point by the axis of rotation of the opening roller in the direction of rotation, is between 10 ° and 65 °, preferably between 10 ° and 45 °, especially between 20 ° and 32 °. This distance influences the opening of the discharge gap and thus the amount of waste and the composition of the waste.
- the knife will then function as a normal guide. Or the knife can be replaced by a baffle and the cleaner shaft would work like a normal filling shaft.
- the feed roller is preferably inclined (measured) at an angle ( ⁇ ) of 25 ° to 90 ° with respect to the opening roller by the axis of rotation of the feed roller and the opening roller relative to the vertical plane by the axis of rotation of the opening roller in the direction of rotation of the opening roller.
- the fiber ejection point should preferably be arranged in such a way that the good fibers are ejected technologically. Since the fiber flakes are released at the transfer point, a long dwell time of the fibers on the opening roller is not technologically sensible, so a quick release has a rapid effect on the entire process.
- a guide surface is arranged between the knife edge and the discharge point, which clearly separates the
- This guide surface can be formed as a separate guide element or together with the knife.
- the knife is preferably extended to the rear, as will be explained in more detail later.
- the knife is preferably folded together with the guide element, which is arranged downstream.
- the knife edge is due to the dirt particles and the fibers that brush over the edges have a high potential for wear. You can either choose a wear-resistant material and / or make the knife edge replaceable.
- An alternative solution is to make the knife and guide element from one piece. Before this, a piece of sheet metal is first made to the desired thickness, the knife edge is ground and then the sheet metal is bent into the desired curvature. This creates a finer knife edge that has no additional
- Fasteners or grooves where dirt or scraps of fiber can hang.
- This manufacturing technique has the advantage that a stable, inexpensive knife that can be exchanged can be manufactured.
- the fastening elements are therefore preferably arranged on the side of this knife, in particular fastening elements that change the setting of the distance
- the degree of cleaning which can be achieved is influenced by the cleaner shaft according to the invention from the distance of the knife edge to the needle tips and from the distance of the knife edge to the transfer point.
- This last knife setting can be adjusted manually or with the help of a drive.
- the setting can take place at predetermined intervals or continuously.
- the setting can be combined with a control which makes or adjusts the setting, preferably depending on the degree of soiling, fiber length or provenance.
- This setting can also depend on parameters that are otherwise measured on the card, for example the number of nits in the outgoing product.
- the speed of the opening roller also has an effect on the degree of cleaning. This parameter can also be integrated in the control.
- FIG 1 Schematic representation of the balance of forces that are exerted on the particles (see description above).
- ⁇ the angle of the inclination of the feed roller with respect to the opening roller measured by the axis of rotation of the feed roller and the opening roller with respect to the vertical plane through the axis of rotation of the opening roller in the direction of rotation of the opening roller;
- ⁇ represents the angle between the knife edge or the beginning of the opening of the guide element and the discharge point, the beginning of the opening of the guide element being the point from where the distance between the guide element and the roller surface begins to increase in the direction of rotation.
- an additional guide element or baffle plate (28) in such a way that the discarded fiber flakes are deflected in the lowermost shaft part. Especially when the total angle comes close to 180 ° to 200 °.
- the flakes are transported between the two rollers until they reach the smallest distance between the two rollers.
- This point is called the transfer point (17) - but is also known as a combing point or combing point.
- the cotton fibers are transferred to the opening roller here. Debris already uncovered is thrown out of the impact circle into the outlet channel (12) according to the centrifugal force acting on it after the transfer point.
- This outlet channel can be in the form of a suction channel, for example, or in the form of a channel which is directed directly downwards, as a result of which gravity aids in the removal.
- the fiber flakes adhering to the clothing of the opening roller are passed directly after the combing point past a knife edge (3), at which further coarse dirt and undissolved fiber knots are eliminated.
- the distance of the knife edge from the transfer point is adjustable, which can influence the amount of waste and thus the cleaning efficiency.
- the good fibers are transported further to the opening roller, along a guide element, which is arranged directly after the knife.
- the fiber material is then dropped tangentially from the opening roller into the lower shaft part (8). There it can be further compressed by air (13) introduced via a compression fan.
- An air stream directed directly at the opening roller to assist in dropping off the flakes and or fibers can also be an option. This air is discharged again via a sieve wall at the rear of the lower shaft (14).
- the cotton wool is placed on the inlet plate 16 of the feed roller of the card by the outlet rollers 15 in the lower shaft.
- FIG. 5 shows a guide element with a knife edge. It can also be viewed as an elongated knife.
- Combinations with parameters measured on the card are also possible, for example adjusting the settings based on a measured parameter on the card, for example neps, thin or thick spots. These can be measured e.g. B. on the fleece in the acceptance area or on the belt.
