Description

[Detailed Description of the Invention] The present invention relates to an improvement of a defibration and dust removing device for a roller card used for carding natural fibers such as worsted, hemp spun, silk spun, and cotton.

Conventionally, fiber opening in this type of roller card has been carried out between mutually rotating rollers, for example, between a cylinder and a walker, and dust removal has been carried out only by a bar beater in the worsted roller card.

However, in these opening and dust removal processes, the opening is carried out between rotating bodies, so opening is carried out in a line, which has the disadvantage that the area is very small and the opening effect is small.

In addition, in the case of dust removal using a bar beater in a worsted roller card, this dust removal is carried out before the fibers are completely divided, so the foreign matter contained in the dense fiber tufts and the foreign matter with a small volume are completely removed. They remain in the fiber tufts without being removed.

These remaining contaminants get stuck between the teeth of the clothing of the cylinder, etc. that performs the fiber-spreading action, and significantly impede the fiber-spreading action.
The contaminants that are stuck between the teeth of the clothing remain in the fibers and are scattered throughout the carded fleece, resulting in a deterioration in the quality of the carded fleece.

The present invention was made to eliminate the above drawbacks,
A defibrating and dust removal device is disposed close to the part where the fibers are separated or transported, i.e., the circumferential surface of at least one roller of the licker-in, cylinder, transporter, etc. The purpose is to separate the impurities from the fibers into a bare state and to remove the dust.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing the main parts of a worsted roller card equipped with the defibrating and dust removing device of the present invention, in which 1 is a presto cylinder, 2 is a main cylinder, and each cylinder is used to open fibers between a walker 3 and a walker 3. I do.

A stripper 4 reduces and transfers the fibers on the walker 3 to the cylinders 1 and 2, respectively.

5 is Dotufa, presto cylinder 1 and walker 3
The receiver takes the fibers opened between cylinders 1 and
Uke passes the fiber to transporter 6.

The transporter 6 transfers the fibers received from the doffer 5 to the main cylinder 2.

Here, as shown in FIG. 2, close to the circumferential surface of the overwire of the presto cylinder 1 and between the walker 3 and the docker 5, the corner 7 on the fiber inlet side on the cylinder side is turned into a pointed position. The defibrated dust removal sheet 9 has a knife shaped knife and has a toothed defibrating body 8 on the inner surface on the cylinder side, and the dust removal sheet 10 has a pointed knife at the corner 7 on the fiber inlet side on the cylinder side. A defibrating dust removal device is constructed by arranging the dust removal sheet 9 on the walker 3 side and the dust removal sheet 10 on the doffer 5 side.

The defibrated dust removal sheet 9 is formed by forming the inner surface 12 of the sheet main body 11 into an arc that is approximately the same as the arc of the overwire circumferential surface of the cylinder.The defibrated dust removal sheet 9 is a sheet-like defibrated body having a serrated wire on the inner surface 12 and teeth in the width direction. A toothed defibrated body 8 such as the above is removably fixed.

Further, the upper surface of the sheet body 11 is formed at an angle α of 40° to 55° with respect to the straight line connecting both ends of the inner surface 12, and a knife is formed on this upper surface with the corner portion 7 at an angle β of 30° to 40°. The sheet 13 is formed by removably fixing the sheet 13 so that the corner portion 7 slightly protrudes from the inside of the sheet body 11.

The dust removal sheet 10 is formed as a knife whose corner portion 7 has an angle θ of 40° to 50′.

In addition, in the defibrating dust removing device configured as described above, the periphery thereof is covered with a cover 14 as shown in FIG. It is also possible to do so, and thereby the dust removal effect can be further enhanced.

Further, in the above embodiments, the defibration and dust removing device is disposed on the presto cylinder, but it can also be disposed on the main cylinder, licker-in, transporter, etc., or it can be disposed in combination with these.

In addition, the arrangement of the defibrated dust removal sheet 9 and the dust removal sheet 10 is as follows:
At least the defibrated dust-removing sheet 9 can be placed at the top, but it is also possible to arrange a combination of a plurality of defibrated dust-removing sheets 9 and dust-removing sheets 10 subsequently.

Since the defibration and dust removal device of the roller card of the present invention has the above-mentioned configuration, contaminants contained in the fibers are squeezed out by the centrifugal force of the roller at the corners of the defibration and dust removal sheet, and contaminants entangled with the fibers are also removed. The fibers are defibrated between the teeth and the fibrillated body, become naked and float on the surface layer of the fibers, and are squeezed off with the corners of the dust removal sheet to remove dust.

Furthermore, the defibrating action of the defibrated dust removal sheet greatly reduces the amount of neps, which has a great practical effect.
