Description

DETAILED DESCRIPTION OF THE INVENTION The present invention modifies a conventional rotary flat card to divide all seven rats into two, and each flat is filled with synthetic rubber at the rear below the knees, with a nine-cloth flat at the front. Saw teeth flats with serrated metallic wires fixed in parallel are placed on the cylindrical part, and the needle density of these 7 rat parts is made denser than coarse, and the 7 rat groups at the positions of the desired needle density distribution are placed on the cylinder. The purpose is to allow the card to rest on the peripheral surface and perform the carding action.

Conventional inventions and ideas of this type include, as in Japanese Utility Model Publication No. 37-4509, in which a clothing tool is fixed on the take-in side of the cylinder, and a sheet with an uneven lower surface and a serrated tip on the dot-fa side is used. There is one in which extraction bars are fixed alternately. This design uses a flat of conventional plain clothing on the tie-in side, which has the disadvantage that fibers accumulate under the needles of the clothing, resulting in progressively poor carding performance. Moreover, since the tooth density of the 7-rat on the docker side cannot be made extremely dense, there is a drawback that the fibers cannot be opened one by one.

Furthermore, as in Japanese Utility Model Publication No. 52-36022, there is a fixed flat card in which a plurality of 7-rat cloths having different needle head densities are arranged in order from the one with the highest needle head density in the carding direction. Publicly known as Ashi, Special Publication Showa 54-225
A carding machine is also known, as disclosed in Japanese Patent No. 25, in which a plurality of fixed flats are attached to the circumferential surface of the cylinder, metallic clothing is fixed on the take-in side, and flexible clothing is fixed on the dosing side.

In all of these inventions and ideas, the flat on the docker side is made by fixing the conventional clothing cloth, so if the needle head density is made extremely dense, the base cloth will be damaged in a short period of time. If you use a flat with a thin needle embedded in it to prevent damage to the base fabric,
The disadvantage is that the needle is damaged in a short period of time. Moreover, since the clothing flat is fixed on the cylinder circumferential surface, the fibers accumulated on the needles of the flat increase with the passage of operating time, and the carding effect gradually deteriorates.

In addition, in Japanese Utility Model Publication No. 52-36022, a fixed flat to which the clothing is fixed is also used on the tie-in side, so
Poor opening tact tends to accumulate in the needle amount of 7 lats, which has the disadvantage that good carding action cannot be maintained for a long period of time.

Furthermore, as in Japanese Utility Model Publication No. 54-22525, there is a known invention in which metallic clothing (corresponding to saw teeth flats) is used on the tie-in side; however, in this invention, metallic wire is used for the flat on the tie-in side. Because of this, the lower part of the tooth is wider. As a result, the teeth of the metallic wire do not penetrate deeply into the tuft which is not sufficiently opened, resulting in the drawback that the opening of the tuft cannot be performed satisfactorily, as described below.

That is, the present invention provides a flat portion AB that is more than half of each of the lower ABC and upper ODA, which are divided into two parts of the entire flat in a rotating flat card.

CD has 7 lats of clothing filled with synthetic rubber below the knee, and the remaining flat parts Be of each part.

DA is a no-cheese flat with serrated metallic wires fixed in parallel, and the needle density of the flats of each part ABC and ODA is from coarse to dense in the carding direction, preferably 10.
From about 0% to about 800 strands/Wyr, each flat ABC, (3DA) flat group at a position with an appropriate tooth needle density distribution is placed close to the cylinder circumferential surface and stationary facing each other to enable carding. This is a stationary 7-rat card characterized in that the 7-rats can be rotated when necessary for inspection, cleaning, etc.

In addition, the several flat cloths at the back in the carding direction of each flat section ABC, ODA AB1CD section have needles that are larger than the diameter of a conventional needle and have a needle angle of 80°-90°.
It is preferable to use a large one.

The gist of the present invention will be explained in more detail using examples as follows.

As shown in Figures 1 and 2, the 7 rat portions AB and CD at the back of more than half of each of the lower ABC and upper ODA, which are divided into two by dividing all 7 rats 4 of the rotating flat card, are filled with synthetic rubber below the knee. The remaining front flat parts Be and DA are sawtooth flats in which sawtooth metallic wires are fixed in parallel (see Fig. 3). The needle head density of the clothing flat, the sawchise flat, and the tooth density (herein, the needle head density and the tooth density are simply referred to as the tooth needle density) are determined by the amount in the carding direction, from extremely coarse to extremely dense, for example, 10
o*7. The range from about 80 to about 80-Jino is divided into 4.5 or more steps and increases, and each of these parts ABC.

The positions of the 7 rat groups of ODA with appropriate tooth density distribution are made to stand still facing each other close to the circumferential surface of the cylinder 10, and the fast pulley 6 and loose pulley 7 are pivotally supported on the driving pulley shaft 5 of the flat 4, A tail end pulley 9 fixed to the end of the cylinder shaft 8 and the above-mentioned pulley 6.7.
This is a stationary flat card characterized by having a belt shifter 11 attached to a belt 10 wound around the belt.

In addition, 2 is a gear inlet, 3 is a doss fan, 12 is a flat drive sprocket gear, 15.15 is a worm gear, 14.16 is a worm, 17 is a flat drive chain, 18 is a needle with a flat cloth, and 19 is a The metallic wire 20 of Sawchies Flat is made of synthetic rubber.

Furthermore, each part ABC of flat, AB of ODA.

The several 72-piece cloths at the back of the carding direction in the qD section have needles that are larger in diameter than conventional needles and have a needle angle of 8.
I am using one that is as large as 0°-90°.

The operation of this invention will be described in detail with reference to embodiments as follows.

Depending on the spinning conditions such as the type and properties of the synthetic fiber staple to be used, the type of pre-opening device, production volume, speed of each part of the card, and the thickness of the spun sliver, the optimum flat needle density distribution can be achieved. First determine the position of the group.

Next, the card is activated while the feed roller (not shown) is stopped, and then the belt shifter 11 is moved to wind the belt 10 around the fast pulley 6. flat 4
starts rotating, so when the flat group at the position of the predetermined tooth density distribution of the flat 4 approaches and faces the circumferential surface of the cylinder 1, the belt shifter 11 is moved and the belt 10
is wound around the loose pulley 7 to stop the flat 4.

At this position, while keeping the rat 4 stationary on the circumferential surface of the cylinder 10, rotate the feed roller (not shown),
Raw materials are supplied to the fiber and the carding action is performed on the peripheral surfaces of the fiber and the cylinder, and a sliver is produced through the card. At this time, the flat was stationary 1! to,
A carding action takes place between a flat with a predetermined needle density and a cylinder. If there are many neps or slabs in the produced card web, or when it is necessary to check the amount of stationary flat needles or the accumulation of fibers between the teeth of metallic wire, or to clean the accumulated fibers, the feed roller should be rotated. After stopping and stopping the supply of raw materials, the belt shifter 11 is moved to wind the belt 10 around the fast pulley 6, and the flat 4 is rotated. When the ABC part of the flat 4 is at the top or the position of the appropriate tooth density distribution of the upper ODA part is close to and facing the circumferential surface of the cylinder 1, move the belt shifter 11 and move the belt 10 to the loose pulley 7. Wind it to stop the rotation of the flat 4. Note that while the flat 4 rotates in this way, the top stripping comb of the conventional rotating flat card,? - The accumulated fibers in the A30 portion of the flat 4 can be cleaned by operating a Kuyular brush, a plus bar comb, etc. (not shown).

The number of 7 rats in each part ABC% ODA of the entire flat is 8 to 9 more than the number of flats that closely face the cylinder circumferential surface and act on the cylinder and carding. Therefore, judging from the degree of opening of the card web, the flat portion ABC or OD is determined from the flat portion ABC or OD, which is held close to the cylinder circumferential surface and facing each other.
Adjust the degree of carding between the flat and the cylinder to be somewhat stronger or weaker by moving the position of the needle density distribution of A somewhat toward the side of higher or lower needle density. Can be done.

Since the present invention operates as described above, it has the following effects.

As described above, in the present invention, the entire flat is divided into two, and the rear half or more of the flats in each part in the carding direction are made into cloth flats, and the remaining flats in each part are made into sawchie flats. The needle density increases from coarse to fine in the carding direction, preferably from about 10-sid to about 80-sid.
Up to about 9 is divided into 4.5 or more stages, and the number of flats that face closely on the cylinder circumferential surface and perform the carding action is 8 to 9 less than half of the total number of flats, so the raw material Depending on the type, properties, spinning conditions, etc., the optimal flat position of the tooth needle density distribution can be placed close to and facing the cylinder surface, which has the extremely remarkable effect of performing the carding action.

Moreover, there are 7 rats ABC, O in each part that divides the whole flat into two.
AB behind the carding direction of DA.

The CD part has a flat clothing, and the lower part of the needle is filled with synthetic rubber, and the density of the needle head varies from extremely coarse to somewhat dense, so the amount of fibers deposited in the clothing is extremely small. Furthermore, by setting the needle angle of the several flats at the rear of the flat portion of the clothing to 80-9()0, it is possible to substantially eliminate fibers deposited in the clothing.

In addition, since it is filled with several flats at the back of the flat part of the clothing, the needle can easily penetrate into the tuft where the fibers have not been opened sufficiently, and the needle can perform a good opening action without being damaged. There is an effect.

Furthermore, in the present invention, each part is divided into two parts (72 pieces)
The front Be and DA parts of ABC%ODA in the carding direction are sawtooth flats with sawtooth metallic wires arranged in parallel and fixed, and the width is increased from coarse to dense in the carding direction.
The densest flat tooth density is up to 800'/', fa degree. Therefore, the fibers in the slab portion, which could not be opened one by one at the front of the flat, can be completely opened one by one. Moreover, since the fibers are opened using metallic wire, no damage occurs even if the tooth density is extremely dense as described above. If the needle cloth is flat and the needle head density is extremely large as described above, there is a disadvantage that the needle cloth is easily damaged.In order to prevent damage to the cloth, serrated metallic wires that reduce the diameter of the needles are fixed in parallel. This has made it possible to eliminate the drawbacks of conventional metallic clothing. Moreover, since the metallic wire has no knees, there is no risk of fibers being deposited between the teeth of the flat, so that a good carding effect can be continuously achieved.
