6: spacer 8: Moat knife

The present invention relates to a mock knife installed on the lower side which is a taker of a carding machine and performing a vibration damping action.

The conventional knife has a triangular shape in the shape of a knife or a cross section, and is installed close to the roller, which is a taker, and is used in fibers caught by the teeth of the dacker, using air flow and centrifugal force on the circumference of the roller, which is a taker. It was designed to remove the scattered fibers and mixed short fibers, but it was difficult to separate the fibers that had entered the fibers, and even if the spinning fibers were in the form of agglomerates, they could not be removed or opened. The drawback of cutting the fibers occurred in the process.

In order to alleviate the above-mentioned shortcomings, many metallic wires are fixedly installed in parallel in the rotation direction of the take-in knife on the mock knife, but the thickness of the bottom of the metallic wire and the thickness of the front end of the tooth It is not enough to divide and open the fiber mass due to the gap, and when the metallic wire is worn or damaged, it requires a great deal of effort to extract and reinsert a plurality of metallic wires. There was a flaw.

The present invention solves the drawbacks of the above-described conventional mock knives, and the blades having teeth in the axial direction of the takers are arranged in a line on the surface of the mock knife main body having a substantially triangular cross section. It is an object of the present invention to provide a moist knife having a large vibration damping effect that can separate the fine particles and short fibers from the fiber by the effective fiber.

EMBODIMENT OF THE INVENTION Hereinafter, one Example of the mock knife of this invention is described according to drawing.

Example 1

One embodiment of the mock knife of the present invention is shown in FIG. 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 an axial groove 2 that is a taker on a surface opposite to a roller, which is a taker. ), And anodized or hard chromium plating was performed.

In addition, it is preferable to form the surface facing the roller which is a taker of the said moat knife main body 1 so that it may have a radius of curvature which is about the same as the radius of curvature of the taker roller.

In addition, the side surface of the moat knife may be provided so that the blade attachment bolt hole 3 and the inside of the groove 2 can be seen, or may be provided through the groove 2.

In addition, when the bolt hole 3 is installed through the groove 2, a hole for bolt insertion through which a position is set in advance is provided in the blade holding the tooth and the spacer plate.

The plurality of teeth 4 protruded in the groove 2 in the rotational direction of the roller, which is a taker, at the top so as to be 10 protrusions / 25.4mm to 20, 20/2 / 2mm in the axial direction of the taker roller. The blade 5 holding the teeth and the plurality of spacer plates 6 are alternately arranged and attached and detached freely in a row, fixed with bolts 7, and the moat knife 8 of the present invention. Configure

In FIG. 1, the blade 5 having four steel teeth is subjected to a hardening treatment such as hardening, hard chrome plating, and thermally sprayed cemented carbide only at the front end of the tooth 4. It is preferable to arrange the blades having a plurality of teeth so that the teeth of the blades having teeth arranged back and forth with respect to the rotational direction of one roller are sequentially or alternately displaced in the axial direction of the roller which is a taker.

The blade holding the tooth may have a dense pitch of the blade which acts first, followed by a dense pitch of the rear blade.

In addition, if the lower part 9 is located above the surface of the moat knife, the dust removal operation can be performed even at the front end of the lower part. 2 is an explanatory view of a state of use of the mock knife of the present invention, wherein the fiber supplied by the feed roller 10 is formed by a wire 12, which is a taker wound around a roller 11, which is a taker. 8). Dust or large contaminants exposed from the fiber from the front end of the moat knife are swept away and dusted, and the fibers are divided and opened at the teeth of the blade retaining teeth, and short fibers or contaminants are separated from the effective fibers and removed. There is a number.

In addition, if the gauge of the blade and the teeth of the taker wire are the same or slightly wider than the gauge of the take-in wire and the front end of the mower knife, the damping and opening effect is good.

Example 2

3 shows another embodiment of the mock knife of the present invention. Only the blades 5 holding the teeth are laminated and fixedly attached as rivets 14 to form the blade stack 15 holding the teeth, so that the blade laminating agent 15 holding the teeth is the moat knife body 1. It inserts into the groove | channel 2 provided in this, and comprises this invention mock knife.

Since the blade stack holding the teeth is integrated, the insertion into the moat knife body is easier and easier to handle. In this embodiment, the spacer plate can be inserted between the blend holding teeth, or the lower portion of the blade holding the teeth by the portion of the spacer plate can be thickened.

In addition, when the lower side of the blade holding the teeth is opened, it is possible to more reliably preserve the blade stack holding the teeth so as not to come out of the top.

In the case of inserting the spacer plate, if the upper surface of the spacer plate is also positioned at the bottom of the tooth of the blade holding the tooth, the front end of the tooth plate can sweep the fibers.

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

Invention: 1.6%

Analysis result of the downside of taker

Charare analysis by Charear Anareiser

As mentioned above, the take-down rate was 0.5% less than the conventional one, and the recovery rate was greatly improved.

In addition, the proportion of lint in the surface is reduced by 14.2%, the transition of effective fibers to the cylinder is improved, and the ratio of trasches is increased by 17.1%.

Since the mock knife of the carding machine of the present invention has the above-described configuration, the arrangement of the teeth can be arbitrarily changed, and the debris and short fibers in the fiber are removed by the teeth of the blade and the front end of the mock knife. Since division and opening can be performed, it has the effect of the improvement of a sliver quality, the increase of a production quantity, the improvement of a recovery rate, etc.

In addition, since the blade of a plurality of teeth of the present invention is freely inserted and detached in the axial direction where the blade holding a plurality of teeth is taken and removed, every or all of the blades retaining teeth are worn even when the teeth are worn or damaged. The invention is intended to have a practical effect that can be easily replaced.
