Description

[Detailed explanation of the device] This device is designed by providing an appropriate number of intermediate rotating rings between the upper rotating disk at the top and the rotating ring at the bottom, and spacing the several disks and rings at appropriate intervals. The rotor is fixed and constitutes a rotor consisting of multiple stages, and the rotor has a plurality of blades in each stage on a circle centered on the rotation center of the rotor at the periphery, with the cutting edges facing outward on a radial line from the rotation center. A single common blade is provided, circular concave grooves are provided in multiple stages on the circumferential surface of the rotating presser roll, each protruding surface faces the cutter, and is wound around each stage of the rotor. By using a fiber bundle cutting device that cuts the fiber bundle by squeezing the fiber bundle between the cutter at each stage and the circumferential surface of the presser roll at each stage, the cutting efficiency can be increased in general, as well as the cutting efficiency. Although the length is short, it provides a highly effective device that can be adapted to cases where a large amount is required at once.

Next, one embodiment of this invention shown in the drawings will be explained.
is an upper rotating disk at the top, 12 is a lower rotating ring at the bottom, and an intermediate rotating ring 13 is located in between.

In this way, the three members are usually connected by a stay (not shown) to form the rotor 1 so that the distance between the three members is maintained appropriately.

Note that the rotor 1 is rotated by a rotating shaft 2.

3 is a knife with a tip 31 on a circle centered on the center of the rotation axis 2.
A large number of common ones are provided in each stage in a radial manner, with the ends facing outward.

That is, the cutter 3 passes through the upper rotating disk 11 and the intermediate rotating ring 13, is fitted into the lower rotating ring 12, and has an annular lid 4 on its head.

Reference numeral 5 denotes a presser roll, which is rotated by a rotating shaft 51 and has a circumferential surface 52.53 consisting of a plurality of stages, facing the blades 3, 3 of each stage of the rotor 1.

Note that 6 is a continuously supplied fiber bundle that is wound around the cutting edges of a large number of blades 3, and 61 is a fiber bundle that has been cut by being pinched between the circumferential surfaces 52 and 53 of the blades 3 and presser roll 5. be.

Further, reference numeral 7 denotes a discharge hole for the cut fiber bundle 61 provided at the center of the lower rotating ring 12 and the intermediate rotating ring 13, and the peripheral edge thereof is an inclined surface 8 facing downward from the center for smooth discharge.

Since this idea is constructed as described above, the rotor 1
If the fiber bundles are consecutively placed in each stage at the same time, fiber bundles that are multiples of the number of stages will be cut at the same time, and the bones of several stages will gather together and fall from the discharge hole.

Therefore, not only can the cutting length be long, but also when cutting lengths are short and a large amount is required at once, the rotor's rotational speed can be increased to avoid straining each part. Cut fibers with a short cutting length can be obtained, which is efficient and allows safe operation.

In addition, since the amount of outer periphery protrusion of the intermediate rotating ring matches the outer periphery protruding amount of the upper rotating disk and the lowermost rotating ring, the fiber bundles sent to each stage are sufficiently differentiated and no vertical disturbance occurs. Furthermore, since the blades of each stage are one piece that penetrates the intermediate rotating ring, there is no difficulty in positioning the blades of each stage, and assembly is easy.

In addition, since the outer periphery of each stage of the presser roll is on a circumferential surface with the same diameter, there is no difference in the contact between the cutter and the presser roll in each stage, and there is no difference in the cutting of the fiber bundle at any stage. It has the effect of making a smooth cut even when all the parts are full.
