The present invention relates to a mock knife that is installed under the take-in of the carding machine to perform the vibration damping action.

Conventional mock knives are generally triangular in knife formation or cross-section and are installed close to the take-in roller and are scattered in the fibers held in the teeth of the take-in by using air flow and centrifugal force on the circumferential surface of the take-in roller. And removing the mixed short fibers. However, the impurities contained in the fibers are difficult to separate, and even if the fibers are spun, they may be removed if they are in the form of agglomerate, or the fibers may not be scattered, resulting in fiber cutting in the next step.

In addition, as a solution to the above-mentioned drawbacks, some metal wires are fixedly arranged on the mock knife in parallel in the rotational direction of the take-in.

However, when the metallic wires are worn or damaged, a number of metallic wires must be pulled out and reinserted, which requires a great deal of effort.

The present invention solves the above-mentioned problems, and the metal wires are arranged in the take-in axial direction in a groove provided with a cross section drilled in the take-in axial direction on the side facing the take-in of the triangular mock knife. The present invention provides a moist knife having a high vibration damping effect that can be easily detached by replacing the installed metal wire attachment gas and detachable from the effective fiber of the impurities and short fibers enclosed in the fiber.

Hereinafter, an embodiment of the mock knife of the present invention will be described with reference to the drawings.

1 shows one embodiment of the mock knife of the present invention. The mock knife main body 1 has an approximately triangular cross section by casting, cutting or extruding an aluminum or aluminum alloy material, and has a groove 2 in the axial direction of the take-in on the side facing the take-in roller. ), And anodized or hard chromium plated.

On the side of the moat knife body 1, the screw hole 3 for attaching the metallic wire attaching machine 4 to the groove 2, or through the groove 2, may be placed at various positions. Install on.

The metallic wire is attached to the metal base 4 in a shape of fitting into the groove 2 of the moat knife body in a quadrangular pillar shape made of aluminum or aluminum alloy.

The metallic wire attachment body 4 forms a plurality of attachment grooves 6 for arranging the metallic wires 5 in rows in the take-in axial direction on a surface opposite to the take-in roller, and also includes a groove 2. The screw hole is provided at the position corresponding to the screw hole 3 of the above-mentioned morte knife main body for fixing to.

As shown in FIG. 3, the steel wires 5 formed in a predetermined shape by rolling, baling, and heat treatment are lined up in the attachment grooves 6, respectively. The attached metal wire attachment body 4 (FIG. 2) is detachably attached to the mock knife main body 1, and it is fixed and attached with the screw 7, and the mock knife 8 of this invention is comprised. In addition, the fixed attachment of the metallic wire 5 to the attachment groove 6 is performed by high dent in, caulking, adhesive bonding, or the like.

By the way, in FIG. 1, the four metallic wires 5 perform heat treatment, hard chromium plating, ceramic thermal spraying, etc. on only the teeth 9, and the teeth of the front and rear metallic wires are taken by the roller. It is preferable to arrange the plurality of metallic wires so as to be displaced in the axial direction.

Moreover, the shape, pitch, etc. of a metallic wire can be changed according to the conditions which spun out, and the specification of each of four metallic wires can also be changed.

In addition, the metallic wire 5 is installed in a row so that the dense bottom portion 10 is located above the upper surface of the metallic wire attachment gas 4 so that the front end of the lower tooth portion is also damped.

The grooves 2 and the attachment grooves 6 are rectangular in cross section, but may also be used as spherical bodies, in which case the fitting becomes more firm.

4 is an explanatory view of the use state of the mock knife of the present invention, the fiber supplied by the feed roller 11 (not shown) is gripped by the take-in wire 13 wound on the take-in roller 12 The moat knife 8 is reached.

The exposed or large contaminants exposed from this fiber are swept away by the front end 14 of the moat knife, and the fibers are separated and scattered by the methyl wire 5, while the short fibers or the contaminants are separated from the effective fiber. It can be damped.

In addition, the tooth tip of the metallic wire 5 and the gauge of the take-in wire 13 are equal to or slightly wider than the gauge of the front end 14 of the mower knife and the take-in wire 13, and the effect of dust removal and fiber scattering is effected. Is good.

Next, the comparison test result of the mock knife of the carding machine of this invention, and the mock knife of the conventional carding machine is shown.

Results of analysis of the contents of take-in

As described above, the take-in drop rate was 0.5% less than that of the conventional one, and the yield was greatly improved.

In addition, the lint ratio in the falling surface is reduced by 14.2%, the transition of the effective fiber to the cylinder is improved, and the ratio of the trecis is increased by 17.1%, so that the impurities are reliably removed.

Since the mock knife of the carding machine of the present invention has the configuration described above, even if the teeth of the metallic wire are worn or damaged, the metallic wire attachment gas can be easily replaced with a new metallic wire attachment body, thereby greatly improving the work efficiency. can do.

Alternatively, it is also easy to install the metal wires on the metallic wire attachment gas so that the manufacturing cost can be greatly reduced.

In addition, depending on the spinning conditions, the metallic wire can be arbitrarily changed in the arrangement of the teeth. The front end of the metal wire and the moat knife can remove impurities and short fibers in the fibers, and separate and scatter the fibers. In addition, since the damping action is also performed in the bottom part of the metallic wire, the present invention has practical effects such as improving the quality of the sliver, increasing the yield, and improving the yield.
