Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a carding machine, and particularly to a technique for improving the carding machine so that the carding rate can be easily adjusted.

[Prior art] One of the main functions of the take-in casing that covers the lower part of the take-in roller of a carding machine is that its tip
The goal is to separate good fibers that are worth spinning from short fibers and impurities that are not worth spinning. That is, contaminants with a high terminal velocity are ejected by centrifugal force in the tangential direction of the take-in roller along with the accompanying airflow, and fibers with a low terminal velocity are introduced into the inside of the take-in casing riding the accompanying airflow. . Therefore, if the gauge between the Take-in roller surface and the Tip of the Take-in casing is made smaller,
Contaminants are less likely to be guided inside the take-in casing.

In order to perform such gauge adjustment, a typical conventional example is as shown in FIG. 4. That is, the wraps 9 on the dish plate 9a fed by the feed roller 4 are opened by the take-in roller 5, and the contaminants 7 are separated from the opened fibers 8 by the take-in casing 1. It is done. At the time of separation, the ratio, ie, the drop rate, is determined by rotating the taker-in casing 1 around the support shaft 6 and finely adjusting the gauge 3 depending on the position of the bracket 2.

However, the adjustment of the gauge 3 is limited due to the relationship between the setting interval between the wire tip wound around the outer periphery of the take-in roller 5, or if the gauge 3 is made extremely small, a large amount of useful fibers will fall together with foreign substances. Above, the flow velocity of the suction airflow near the tip of the Take-in casing 1 increases, and the dust etc. floating around is guided into the inside of the Take-in casing 1, which limits the adjustment range of the foreign matter removal function. .

Also, depending on the value of Gauge 3, fibers may easily get caught at the tip of the casing, and Gauge 3 needs to be adjusted taking into account not only the drop rate but also the catching of fluff. Since the degree of freedom for adjustment is 1, it was difficult to adjust to satisfy both the drop rate and the degree of catching of the fluff.

[Problems to be Solved by the Invention] Therefore, in the conventional technology, the adjustment range for fallen objects is approximately 1
%, and due to gauge changes, the fibers at the tip of the take-in casing were heavily caught, causing sliver unevenness. An object of the present invention is to promptly solve such problems.

[Means for Solving the Problems] For this purpose, the present invention provides a take-in casing assembly disposed below a take-in roller between a cylinder and a date plate of a carding machine. a first taker-in casing disposed in the first taker-in casing, and a second taker-in casing rotatably attached to the tip of the first taker-in casing on the date plate side, the second taker-in casing comprising: The taker-in roller should be detachable from the first taker-in casing so that it can be selected from a plurality of different lengths in the circumferential direction of the taker-in roller and attached to the first taker-in casing. It is characterized by:

[Function] In this way, the taker-in casing is composed of two casings, and the second taker-in casing is rotatable and detachable from the first taker-in casing, and the second taker-in casing can be used in various ways. You can choose from lengths. Therefore, the drop rate can be adjusted by changing the length of the second taker-in casing and adjusting the free space between the date plate and the tip of the second taker-in casing. The degree to which the fibers are caught on the tip of the take-in casing can be adjusted by adjusting the gauge between the take-in roller and the take-in casing. Moreover, such free space and gauge adjustments are made separately and independently.

[Embodiments] Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which the same reference numerals indicate the same or corresponding parts.

FIG. 1 shows an embodiment of the present invention, with reference numeral 1
9 to 9 are as described in relation to the prior art. According to the present invention, the tip of the first take-in casing 1 that covers the lower part of the take-in roller 5 located between the cylinder 13 and the date plate 9a;
That is, a cartridge type adjustment second taker-in casing 10 is disposed above the end portion on the side of the dish plate 9a. This adjustment casing 10 has a bracket 2 that supports the take-in casing 1 at approximately the center in its longitudinal direction, that is, in the circumferential direction of the take-in roller 5 in the drawing.
It is rotatably and removably supported by a bracket similar to , and also by a support shaft 12 at the end on the taker-in casing 1 side.

An elongated hole 2a is bored in the bracket 2 as shown, and a suitable attachment means such as a bolt 2b is inserted through the elongated hole 2a and screwed onto a machine base (not shown). By adjusting the position of the elongated hole 2a with respect to the bolt 2b, the adjustment casing 10 can be rotated about the support shaft 12, that is, the gauge 3 can be adjusted.

In addition to having the length shown in FIG. 1, the adjustment casing 10 may have the length shown in FIG. 1, as well as the length of the adjustment casing 10, so that the distance between the adjustment casing tip and the tip of the date plate 9a, that is, the free space 11, can be adjusted. As understood from Figure 2 A and B,
Casings 10a, 10b with various dimensions,
...is available. Reference numeral 2c is a mounting hole for the bracket 2.

Therefore, according to the present invention, by replacing the casing 10, the free space 11 is replaced by the casing 1.
The gauges 3 are configured to be individually adjustable by adjusting the rotation amounts of 0, 10a, and 10b.

As mentioned above, in the past, the falling rate was adjusted by adjusting the gauge 3, which caused the above-mentioned problems, but in the present invention, the free space between the take-in casing and the date plate has been adjusted. The idea is to adjust the dropout rate using space. By making the free space 11 smaller, the outward bulge of the accompanying airflow becomes smaller, and foreign matter that flies out in the tangential direction has a stronger tendency to be guided inside the under casing. The opposite result is obtained, and the adjustment range of the free space 11 is wider than that of the gauge 3, and the effect of removing impurities is greater.

On the other hand, in the present invention, the gauge 3 is used to adjust the degree of fiber catching at the tip of the casing, and the most suitable fiber is adjusted by adjusting the elongated hole 2a and bolt 2b of the bracket 2. It can be set to gauge 3 for the degree of hooking. Further, as shown in FIGS. 3A and 3B, it is preferable that the adjusting casing 10 has a round tip or an acute angle tip 10c, 10d, . . . . For example, if the fiber to be opened is a synthetic fiber, it is best to use the adjustment casing 10c with a round tip to prevent the fiber from getting caught, and if it is cotton fiber, there will be a lot of foreign matter, so use the casing 10d with an acute angle tip. It is preferable to do so. Of course, these casings 1
0c and 10d are also the casings 10 and 10 mentioned above.
It can be attached in the same way as a and 10b.

[Effects of the Invention] As described above, according to the present invention, since the drop rate is a free space and the degree of fiber catching can be adjusted separately and independently using a gauge, the adjustment work is not only facilitated, but also You can choose the most appropriate gauge for fiber catching at the tip of the casing. Moreover, since the drop rate is adjusted in a free space with a wide adjustment range, the adjustment range is widened to approximately 1 to 5%, and the drop rate amount becomes more accurate.

Further, in a preferred embodiment, the tip of the casing can be selected from an appropriate shape depending on the type of fiber to be opened.
