Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD This invention relates to a device for preventing fluff from accumulating on the side of a cylinder undercasing of a carding machine.

BACKGROUND ART In general, a carding machine has a cylinder undercasing 2a below a cylinder 1, as shown in FIG.

2b is disposed, and a rotating flat 4 supported by a 71 noxible pend 3 is disposed above. A front concentric bend 6 is provided on the lower dot 5 side of the flexible bend 3, and a back concentric bend 8 is provided on the take-in roller 7 side. Also, the cylinder 1 between the rotating flat 4 and the dolphin 5
Freon 1 to plate 9 are arranged around the rotating flat 4 and take-in roller 7, and a fixed flat 1 is arranged between the rotating flat 4 and the take-in roller 7.
0 or a back plate is provided. In this way, most of the area around cylinder 1 is covered, so
The airflow generated inside the cover by the rotation of the cylinder 1 flows to both sides, and the fibers that have left the sandwich between the cylinder 1 and the rotating flat 4 are blown out to both sides by the airflow.

As shown in FIG. 2, the conventional cylinder undercasings 2a, 2b are connected to the cylinder 1 with respect to the machine frame 13 by means of support bolts 12 as support members that are fitted into support plates 11 protruding from both ends. Gauge adjustable support. For this reason, the fibers blown out by the rotation of the cylinder 1 become fluff and form the cylinder under casing 2a.
, 2b and the inner surface of the frame 13.

At this time, the support bolt 12 serving as a support member acts as a resistance, accelerating the adhesion and accumulation of fly fluff, and the fly fluff F begins to hang down around the support bolt 12. This hanging fluff E is carried towards the bends arranged above by the action of the suction airflow of the rotating cylinder 1, and is subjected to strong friction between the cylinder 1 and each vent, becoming a cotton mass and moving into the cylinder. There is an inconvenience that the rotation of 1 is hindered. or,
The hanging fluff F interferes with the circumferential edge of the dosing cloth 5 or the edge of the web, disturbing both ends of the wear and causing web unevenness, which not only causes uneven sliver weight but also causes sliver breakage. There was an inconvenience.

In addition, the frame 13 and the cylinder under casings 2a, 2
Since the airflow blown out from the gap with the end of the carding machine is extremely strong, turbulence occurs in the airflow at the bottom of the carding machine stand, which increases the above-mentioned disadvantages and makes it difficult to control the airflow at the bottom of the carding machine stand. Ta.

And with the recent increase in the speed of machines, 41
The blowout amount of 1ff increased, making the above-mentioned problem more likely to occur. For this reason, spinning mills had to stop and clean the machines at least once a day.

Purpose This invention was made to solve the above-mentioned conventional problems, and its purpose is to prevent fluff from adhering to and hanging down in the gap between the end of the cylinder undercasing and the inner surface of the frame, and to prevent fluff from hanging down. To provide a device for preventing air fluff from accumulating on the side of a cylinder undercasing of a carding machine, which can eliminate web unevenness and sliver breakage caused by the web unevenness, and facilitate control of airflow at the bottom of the carding machine table. There is a particular thing.

Structure of the Invention In order to achieve the above-mentioned object, in this invention, at a position above the support member for supporting the cylinder under casing between the inner surfaces of the machine frame, the ends of the cylinder under casing and the inner surface of the machine frame are connected. A fixed guide member is provided on either side to extend along the side surface of the cylinder under casing, and a slide member is provided along the fixed guide member so as to be able to slide to a position where it abuts during use and to be able to be held at the abutting position. Ta.

Example 1 A first example embodying the present invention will be described below with reference to FIGS. 3 to 7. The device of this embodiment differs greatly from the conventional carding machine in that a member is provided to close the gap between the end of the cylinder undercasing and the inner surface of the side wall of the machine frame, and the other configurations are Basically, it is the same as the conventional device, and the same parts are denoted by the same reference numerals and the explanation will be omitted.

The cylinder undercasing that covers the lower circumferential surface of the cylinder 1 is composed of a front cylinder undercasing 2a disposed on the docker 5 side and a back cylinder undercasing 2h disposed on the taker-in roller 7 side. Both cylinder under casings 2a and 2t+ are removed 1
The inner surface of the side wall of the machine frame 13, which is rotated, is formed into a smooth surface. As shown in FIG. 3, bolt holes 14 are formed in the support plates 11 disposed at both ends of the cylinder undercasings 2a, 2b at both front and rear sides of the lower part thereof.

As shown in FIGS. 4 and 6, the cylinder under casings 2a and 2b have bolt holes 4 members 15 whose positions can be adjusted from the outside of the frame 13 using position W adjustment bolts (not shown).
The cylinder 1 is attached to the frame 13 by a support bolt 12 and a nut 16, which are screwed into the bolt hole 14 through the frame 13, so that the gauge of the cylinder 1 can be adjusted. As shown in FIG. 6, the bolt insertion holes 17 formed in the frame 13 are formed to have a larger diameter than the support bolts 12 so as not to interfere with the vertical movement of the cylinder undercasings 2a, 2h during gauge adjustment.

A cylinder under casing 2 is installed on the outer upper part of the support plate 11.
Fixed guide member 1 formed in an arc shape along a and 2h
8 is fixed. Below the fixed guide member 18, guide bins 19 are protruded from both front and rear sides of the outside of the support plate 11.
When the slide member 20 formed in an arc shape is in the fitting hole 21 with its upper surface in contact with the lower surface of the fixed guide member 18,
It is supported by the guide bin 19 so as to be slidable in the lateral direction. Two screw holes 22 are formed in each of the slide members 20, and bolts 24 are inserted into the screw holes 22 loosely from the outside of the frame 13 into insertion holes 23 formed in the frame 13, as shown in FIG. They are screwed together. Incidentally, the insertion hole 23 is also formed to have a diameter that does not interfere with the gauge adjustment of the cylinder undercasings 2a, 2b, similarly to the pole 1 insertion hole 17.

Next, the operation of the apparatus configured as described above will be explained. The cylinder under casing 2a is secured by the support bolt 12, bolt attachment member 15 and nut 16.

2b is attached and fixed to the frame 13 so as to be at a predetermined position and a predetermined gauge with respect to the cylinder 1. This state is the state shown in FIGS. 4 and 6.

When the bolt 24 is rotated in this state, the slide member 20 is guided by the guide bin 19 and moves with its upper surface slidingly in contact with the lower surface of the fixed guide member 18.

When the rotation of the bolt 24 is stopped with the slide member 23 in contact with the smooth surface of the fly 1813, the slide member 20 is fixedly held at that position. In this state, the gap between the cylinder undercasings 2a, 2b and the inner surface of the frame 13 is completely closed by the fixed guide member 18 and the slide part +J20, so that the airflow generated by the rotation of the cylinder 1 during operation of the carding machine is prevented. Passage is closed. Unlike conventional devices, this reliably prevents fluff carried by the blown airflow from adhering to the gaps between the ends of the cylinder undercasings 2a and 2b and the inner surface of the frame 13 and hanging down around the support bolts 12. Ru.

Embodiment 2 Next, a second embodiment of the present invention will be described with reference to FIGS. 8 and 9. This embodiment differs from the previous embodiment in that a fixed guide member 18 and a slide member 20 for closing the gap between the ends of the cylinder undercasings 2a, 2b and the inner surface of the frame 13 are attached to the frame 13 side. The equipment is very different. As shown in FIG. 8, the structure of the cylinder undercasings 2a, 2b is the same as that of the conventional device. A fixed guide member 18 is fixed on the inner surface of the frame 13 facing the support plates 11 disposed at both ends of the cylinder under casings 2a, 2b, and a guide bin (not shown) is protruded below the fixed guide member 18. There is. A slide member 20 is supported on the guide bin so that it can move toward the ends of the cylinder undercasings 2a-, 2b with its upper surface in vibrational contact with the lower surface of the fixed guide portion jtA 1 B.

Two stud bolts 25 are provided protruding from the frame 13 side of the slide member 20, and an adjustment nut 27 is screwed into the distal end of the slide member 20, which passes through an insertion hole 26 formed in the frame 13 and protrudes to the outside of the frame 13. are combined. In this device, after the cylinder undercasings 2a, 2b are installed at a predetermined (i?) position, when the adjusting nut 27 is rotated, the slide member 20 moves between the cylinder undercasings 2a, 2b.
If the adjustment nut 27 is stopped rotating when it moves toward the end of the cylinder undercasing 2a, 2h and comes into contact with that end, the slide part +420 will be held at that contact position, and the cylinder undercasing 2a, 2h end and frame 13 The gap with the inner surface is completely sealed. Therefore, in this device, as in the device of the above-described embodiment, there is no possibility that fly fluff riding on the airflow generated by the rotation of the cylinder 1 adheres to the gaps between the cylinder under casings 2a, 2h and the frame 13 and hangs down.

Note that the present invention is not limited to the above-mentioned embodiments. For example, as shown in FIG. It may be placed in In this case, the cylinder under casings 2a, 2b
Since the groove formed by the end portion, the slide member 20, and the inner surface of the frame 13 is shallow, fluff is less likely to accumulate in the groove.

Note that if the lower surface of the support plate 11 in contact with the upper surface of the slide member 20 is cut to be smooth, the fixed guide member 18 is not necessarily required. Furthermore, as shown in FIG. 11, a fixed guide member 18 and a slide member 20 are attached to the frame 13.
The vertical relationship may be reversed. Furthermore, it is also possible to arbitrarily change the shape, structure, etc. of each part without departing from the spirit of the invention, such as by applying the cylinder undercasing to a structure in which the cylinder undercasing is divided into three parts: front, middle, and back.

Effects As detailed above, according to the present invention, the gap between the end of the cylinder undercasing and the inner surface of the frame is completely closed, so that the fluff carried by the airflow caused by the rotation of the cylinder adheres to and accumulates in the gap. It does not grow to the point where it hangs down, and it is possible to reliably prevent the sliver from breaking due to disturbances in the running of the web.In addition, the airflow from the gap to the bottom of the 11m carding table is eliminated, and the airflow at the bottom of the machine table is eliminated. Qin has a good effect of being easy to control.
