It is.

BACKGROUND TECHNOLOGY Below the take-in roller between the cylinder of the carding machine and the dish plate, there is a roller that separates good fibers to be spun from unnecessary short fibers and impurities.
A take-in under casing etc. will be placed.
When changing the raw material of cotton or changing from cotton to synthetic fibers, replace the under casing with one that has a different length or date plate side edge shape depending on the type. There is a need to.
Conventionally, the take-in roller, feed roller, dish plate, etc. were once removed before replacement, and after replacement, the gauges of the take-in casing, etc. were adjusted, and then they were reassembled. Therefore, each time a change is made, disassembly and reassembly work must be performed, making the work extremely complicated. Therefore, for example, Japanese Patent Application Laid-open No. 61-266619 has been developed to enable replacement without performing these operations
There is something described in the publication. This consists of dividing the Teikain under casing into two parts, using the Teikain undercasing on the dish plate side as a replacement, and attaching it to the other Teikain undercasing via a support shaft so that it can rotate freely. It is shown.

Problems to be Solved by the Invention However, with the above configuration, the replacement Teikain under casing is attached to the other Teikain undercasing via a support shaft, so gauge adjustment is always required after installation. Therefore, it was time-consuming and troublesome.

Measures to solve the problem Divide the take-in under casing into the main casing on the cylinder side, which has a long length in the arc direction, and the auxiliary casing on the date plate side, which has a short length in the arc direction, and separate the main casing and the auxiliary casing. A mounting part that can be connected integrally is provided on the split side part of the main casing, and the main casing is mounted on the side frame so that its position can be adjusted freely.The mounting part of the auxiliary casing can be attached and detached to the main casing mounting part using a mounting bolt. It is characterized by being attached in one piece.

Function To assemble the take-in under casing, connect the auxiliary casing to the main casing using the mounting parts provided on the split sides of the main casing and auxiliary casing, and then simply tighten the mounting bolts while maintaining this joined state. This can be done by installing them in one piece. Therefore, to replace the take-in under casing, select one with the desired arc length and shape from a plurality of auxiliary casings prepared in advance according to the type of fiber, and then install the auxiliary casing. This can be achieved with The replacement can be carried out by going under the take-in roller and attaching and detaching the auxiliary casing.

Embodiment 1 is a feed roller, 2 is a date plate 3 is a cylinder, 4 is a take-in roller disposed between the date plate 2 and the cylinder 3, and both ends thereof are connected to a pedestal 5 attached to a side frame 6. It is pivoted. Takein roller 4
A shroud plate 8 is provided between both side surfaces 4a of the pedestal 5 and the side frame 6, the upper part of which is fitted into a groove 7 formed in the inner lower part of the pedestal 5 and fixed thereto. Reference numeral 9 denotes a moat knife disposed close to the lower peripheral surface of the take-in roller 4 on the side of the date plate 2, and a moat knife bracket 10 is attached to each shroud plate 8 so as to be adjustable back and forth by a mechanism not shown. It is fitted into the groove 10a of. The moat knife 9 is held by a screw (not shown) so that it can be adjusted up and down, and the distance between its tip and the nose portion 2a of the dateshield plate 2 and the gauge between the take-in roller 4 and the take-in roller 4 are adjusted respectively. It is now possible to adjust the amount of material. If the distance between the tip of the moat knife 9 and the nose portion 2a is to be changed significantly, the moat knife bracket may be replaced with another moat knife bracket in which the groove 10a is formed in a different position, as shown in FIG.

Reference numeral 12 denotes a take-in under casing arranged close to the lower circumferential surface of the take-in roller 4 on the cylinder 3 side, and a casing bracket 16 whose main casing 14 (to be described later) is attached to each shroud plate 8. It is attached to the upper surface 16a of the holder with a mounting bolt 17. The casing bracket 16 is fixed to the shroud plate 8 by a mounting bolt 21 inserted through an elongated hole 20 thereof. An adjustment bolt 22 is inserted through the casing bracket 16 from the center of the lower surface 16b and is screwed into a screw hole 23 of the shroud plate 8. Further, a hexagon socket adjustment screw 24 is screwed from the lower surface 16b so as to sandwich the adjustment bolt 22, and is in contact with the lower surface 8b of the shroud plate 8. Thereby, the casing bracket 16 can be finely adjusted up and down, and the gauges of the take-in under casing 12 and the take-in roller 4 can be adjusted. The take-in under casing 12 is located almost directly below the take-in roller 4 and consists of a main casing 14 on the cylinder 3 side, which has a long length in the arc direction, and an auxiliary casing 15 on the date plate 2 side, which has a short length in the arc direction. It is divided. The main casing 14 and the auxiliary casing 15 are constructed by processing cast molded products. The split side portion of the main casing 14 has a mounting surface 3 that is perpendicular to the bottom surface 14b of the main casing 14.
0a and a positioning surface 30b formed by the end of the bottom surface 14b. A plurality of screw holes 32 are directly cut into the mounting surface 30a of the main casing 14 at predetermined intervals in the axial direction of the take-in roller 4. The split side portion of the auxiliary casing 15 has a mounting portion 31 comprising a contact surface 31a that contacts the mounting surface 30a and a hook-shaped locking portion 19 that contacts the position determining surface 30b.
is formed. Further, when the auxiliary casing 15 is integrally connected to the main casing 14 by the mounting portions 30 and 31,
Attachment holes 33 are bored at positions corresponding to the screw holes 32, and the auxiliary casing 15 is integrally attached to the main casing 14 with attachment bolts 26. A plurality of auxiliary casings 15 are prepared in which the shape of the portion close to the circumferential surface of the take-in roller 4 has an optimal shape depending on the type of each fiber.

In the present invention configured as described above, when the carding machine is operated, the take-in roller 4 scrapes the fibers fed by the feed roller 1, and the foreign matter mixed in the scraped small fibers is removed. are separated and removed between the date plate 2 and the moat knife 9 by the action of centrifugal force, and the unnecessary materials are allowed to fall. Then, the good fibers to be defibrated are suctioned with a moat knife 9.
It is collected again onto the taker-in roller 4 through the lower part of the cylinder 3 and supplied to the cylinder 3 side. In that case, the take-in under casing 12 is constructed by fixing the main casing 14 and the auxiliary casing 15, both of which are machined castings, together with the mounting bolts 26.
Vibration can be reduced, and the cotton drop adjustment can be performed stably in the same way as the take-in under casing 12, which is made of one piece. FIG. 1 shows the case of defibrating cotton with a lot of foreign matter mixed in. The moat knife 9 is placed far away from the date plate 2 so that the amount of fallen matter is large, and the main casing 14 is installed. An auxiliary casing 15 having a shape shown in the figure and having a short length in the arc direction is attached to the portion 30. Next, when changing the fiber material to defibrate synthetic fibers that do not contain a lot of contaminants from the above state, move the moat knife 9 to a date shuffle as shown in Figure 3 to reduce the amount of fallen debris. The auxiliary casing 15, which is disposed close to the plate 2 and has a short length in the arc direction, is replaced with an auxiliary casing 15' having a shape shown in the figure and having a long length in the arc direction. For this replacement, remove the mounting bolt 26 from below the take-in roller 4, remove the auxiliary casing 15, position the new auxiliary casing 15' for replacement by the mounting parts 30, 31', and integrally connect it to the main casing 14. death,
While maintaining this connected state, it is attached using the attachment bolt 26. In that case, the auxiliary casing 15'
By fixing the auxiliary casing 15' to the main casing 14 with the mounting bolts 26, the auxiliary casing 15' is positioned, and subsequent gauge adjustment between the auxiliary casing 15' and the take-in roller 4 can be made unnecessary. In this way, the auxiliary casing 15 is selected to have an optimal shape depending on the type and properties of the fibers. As described above, according to the present invention, the take-in under casing 12 can be easily replaced by replacing the auxiliary casing 15 without removing the take-in roller 4, the date plate 2, etc.

Effects of the invention As described above, in this invention, the take-in under casing is divided into the main casing on the cylinder side, which has a long length in the arc direction, and the auxiliary casing on the dish plate side, which has a short length in the arc direction. Therefore, when replacing the take-in under casing, you only need to replace the auxiliary casing without removing the take-in roller or date plate.
It can save a lot of time and effort. In addition, the main casing and the auxiliary casing are provided with attachment parts that can be integrally connected to each other on the divided sides, and the attachment part of the auxiliary casing is detachably attached to the attachment part of the main casing using a mounting bolt. Therefore, the auxiliary casing can be easily integrally connected to the main casing through the mutual attachment parts, and as a result, gauge adjustment can be made unnecessary and the effort required for changeover can be reduced.
