JPS6099016A - Apparatus for removing dust from surface of cylinder of card - Google Patents

Abstract

PURPOSE:To provide a card capable of removing even small and light trash in high efficiency, by placing a covering member having a knife-edge end at a specific position between the front door and the front top-sheet covering the doffer-side surface of a cylinder. CONSTITUTION:The second front top-sheet 16 acting as a covering member having knife-edge end is placed between the front door 12 and the front top-sheet 15 covering the doffer-side (7) surface of the cylinder 4. The gap (slit) between the front end of the second front top-sheet and the rear end of the front top-sheet 15 is adjusted to about 3-10mm.. The gauge G1 at the delivery end of the front top- sheet 15 is made to be equal to or larger than the gauge G2 of the second front top-sheet 16.

Description

[Detailed Description of the Invention] Technical Field This invention relates to a device for removing dust from the cylinder surface I- of a card, and particularly relates to a dust removing device for removing top dust from the cylinder surface on the top P side. .

PRIOR ART In general, a card is shown in FIG.
, a cylinder 4, a rotating flange 1-0 supported by a flexible bend 5, a dotting device 7, and a dotting device 8. The wrap (not shown) supplied by the action of the dish plate 1 and the noid roller 2 is transferred to the take-in roller 3. combs, removes dust, and opens the fibers, and sequentially transfers them to the cylinder 4, and through the action of the rotary furazo l-6 cylinder 4, removes small fruit scraps, leaf scraps, and short fibers that were not removed by the take-in roller 3. Except, clean 1, T
Separate each fiber into pieces and transfer them to Dotsufa 7.
The fiber layer is then formed into a fiber layer again and taken out as a web from the dock 17 by dotting process 8.

Also, a back plate 1 or a fixed flange 1 is provided around the cylinder 4 between the taker in roller 3 and the rotating flanges 1 to 6.
9 is taken out via back contact I to Rick Ben 1 to '10 (d4), and around the cylinder 4 between the dot 7 and the rotary flat 6 there are 1 to 1 to 1 to 1 to 11 to 1 to 1. A front door 12, front 1, bottom 1, and seat 13 are attached via a front concentric bend 14. And the Lalonto top sheet 11
,ノ[]]nt door 12 front 1-bottom sea 1-13
C is connected so that there is no gap between each other.
Although the surface of the cylinder 4 was covered with (), no action was taken on the fibers on the surface of the cylinder.

Conventionally, when the amount of 1 to lassi in the raw cotton of Pakistani cotton varies widely, ranging from 5 to 13%, lash hanging on the yarn 1 often becomes a problem. The large and heavy trash 1 of 1 to lash 1, such as actual waste, can be removed relatively easily using the flNJ cotton machine or card C, but the lash I, which is a problem with yarn, is small and light and has a very low terminal velocity. A reserve amount 11 such as a fixed flat 9 is provided between the take-in roller 3 and the rotating flat 6.
It is very difficult to remove i-lash even if you put the device in place.1
1 (-there was.

Purpose This invention is based on the above-mentioned conventional problem, and its purpose is to efficiently remove small and light toshes that are problematic with threads. An object of the present invention is to provide a device for removing dust on the surface of a cylinder.

Structure of the Invention A') In order to achieve the above-mentioned object, the present invention includes front top sheets 1 to 1 which cover the surface of the cylinder on the trough 7 side.
and the door, the tip thereof is formed into a knife shape, and a second cover member is connected between the tip of the cover member and the door.
] A slit of 3 to 1 Qnv is formed between the front 1 and the rear end of the top sheet, and the relationship between the gauge G1 at the rearmost part of the front 1 to top sheet and the gauge G2 at the tip of the cover member is determined. 01≧02.

°Example An example embodying the present invention will be described below with reference to Figs. 2 to 6.
The structure between Rough 7 and 7 is different from the conventional one. Near the rotating flange 1-6, there is a first front l-h tube seat 1, which corresponds to the conventional)
- 15 are arranged, and a second foot sheet 16 as a cover member is disposed on the downstream side of the first stump sheet 1-15, and a second foot sheet 16 as a cover member is connected to the tip thereof and [1 to 3 between the tip 1 and the rear end of the tube sheet 15.
A slit S having r4A for about 100 seconds is formed at J and C. Both front top seas 1~I! The tips of i and i6 are both formed into a knife shape. First Front Top Seas 1 to 1 (i has a gauge between the tip and the surface of the cylinder 4, which is the same as in the past, 20/1000 to 40/1000 inches. -1<0°508~1.016IIIm), the gauge between the rear end and the surface of cylinder 4 is 30/100'O~50
/ 1000 inches (0,762 to 1.27 mm). As shown in Fig. 4.5, the second sheet 16 has stepped portions 17 formed at both ends thereof, and a through hole 13 and a screw hole 19 formed at the bottom. . ξ and MV the jΔ hole 1B
1. Bolts (I! shown in the figure) that are screwed into the unit 14 are screwed into the screw holes 19 and 1. The gauge between the surface of the cylinder 4 and the surface of the cylinder 4 can be adjusted independently using an adjustment bolt (not shown). Second Freon H l - The gauge 02 between the tip of the tube seat 16 and the surface of the cylinder 4 is the gauge G1 between the rear end of the front front 1 - top seats 1 to 15 and the cylinder surface 4. The relationship is G1≧G2. : Sea urchin 20/1000~40/1000 inch ('0.50
8~1°016mm).

Next, the operation of the apparatus constructed as described above will be explained. Now, the cylinder 4, the take-in roller 3, the fixed flazo [-
9. Due to the action of rotating flat 6, the fibers are opened and removed, and the fibers advancing toward the docker 7 side of the cylinder 4 are removed from the heavy toshes, but this becomes a problem with the yarn. The small and light 100% fibers have not yet been removed and move to the surface of the cylinder 4 along with the fibers.

After passing through the rotating flange h6, the fibers are in a very young state on the surface of the cylinder 4, so the tosh ゛T is protruding from the surface of the fiber. -1- is front top sheet 15 and second front [1st 1-large seat 16]
When moving to the point C1~S formed between the sleeves 1~S, Tosh] moves further outward from the surface of the cylinder 4 due to centrifugal force or the action of airflow blown outward from the sleeves 1~S. , due to the action of the tip of the second front top sheet '1 [5 formed in the shape of a buino 1-tube, it is moved away from Ili navy blue by a certain amount l1iI1Δ (extruded to the outside. In this case, if the spacing between the sleeves t-S is too narrow If the action of the exhaust airflow to the outside is weak and the removal action of the truss 11 is almost non-existent, and the width of the sleeve l-S is too large, it will be necessary to remove it. There is an inconvenience that even the fibers are discharged to the outside by the discharge airflow from the slit hS.The inventor of the present invention has determined the ratio of the waist discharged from the slit S to the amount of fiber supplied by varying the width of the slit S. Senmei on strike 1
The trash of fruit scraps, leaf scraps, garbage, etc. except for one minute was measured on the skewer. The results are shown in Figure 6. As a result, the sleeve +
The width of -S is preferably 3 to 1101I1, and especially in this experiment, 5mm is the best.

J3 This invention is not limited to the above embodiments.
7 <, for example, the front door 1 as shown in FIG.
2 is formed into a knife shape, and a triangular bar 20 is provided in place of the hikand front 1 - tongue seat 16, and as shown in Fig. 12 and between the flon 1 and the bottom sheet 13. Dust removal efficiency is improved by installing not only one slot but multiple slots.

According to this invention, it is possible to efficiently remove toshes that are difficult to remove with conventional carts, or that are small and light and cause problems with yarn C. 1) When using Pakistani cotton with a high tosh content, high quality yarn can be made with excellent effect.
