Embodiments of the present invention will be described with reference to the accompanying drawings. The illustrated example relates to a noodle making machine, and FIG. 1 is a longitudinal sectional view of a rolling mill provided with a scraper according to the present invention, and FIG. 2 is a front partial view thereof. In the figure, reference numeral 1 denotes a side plate that supports the shafts of a pair of rolling rolls 2 and 3.
One is connected with a plurality of stay rods 30 (see FIG. 2).
A scraper is provided between the side plates 1 and 1 so as to be close to the rolling rolls 2 and 3.

Each of the scrapers includes a rotating shaft 6 supported between the side plates 1 and 1, a blade supporting plate 7 fixed to the rotating shaft 6, and a blade 8 attached to an end of the blade supporting plate 7. Be composed. The blade 8 has substantially the same width as the rolling rolls 2 and 3, and comes into contact with the peripheral surfaces of the rolling rolls 2 and 3 at one rotation end of the blade support plate 7 (the state shown by the solid line in FIG. 1).

The scraper is provided with lock mechanisms 4 and 5 at one or both ends of a rotating shaft 6 thereof. This is shown in FIGS.
As described with reference to FIG.
(See FIG. 2). The former is a spacer plate 9, which is in contact with the side plate 1, a holding plate 10, and is sandwiched between the two plates 9, 10. Receiving block 11 and rotator 12 received and supported on the upper surface of receiving block 11
And an up-and-down plate 13 having one end pivotally supported on the upper surface of the receiving block 11 and performing an up-and-down operation in accordance with the operation of the rotator 12. The rotator 12 has a square hole 12a and a protrusion 12b.

The receiving block 11 has a receiving hole 15 into which a receiving member 14 for supporting the rotor 12 is fitted, and a buffer spring 16.
And a female screw hole 18 communicating with the receiving hole 15 and a female screw hole 19 communicating with the spring hole 17 are respectively formed from the lower surface. The female screw hole 18 and the female screw hole 19 are respectively provided with bolts 21, 2
2 is screwed.

A support pin 2 is attached to one end of the undulating plate 13.
3 is formed. In addition, receptor 1
4 is made movable vertically in the receiving hole 15, and a push-up spring 25 for constantly pushing up the rotating element 12 and making contact with the up-and-down plate 13 is provided at the bottom thereof.

On the other hand, a portion of the lock mechanisms 4 and 5 fixed to the scraper is a lock plate 26 fixed to the rotating shaft 6 of the scraper. The lock plate 26 has a lower surface that contacts the undulating plate 13, and the lower surface is curved on both sides.

The holding plate 10 is substantially the same size as the spacer plate 9 and has a square hole 12
A notch 28 for exposing a is formed.

The operation of the above mechanism will be described with reference to FIGS. 1, 7 and 8. To release the scraper from the locked state shown in FIGS. 1 and 7, a square wrench is used from the inner side of the side plate 1. A hexagon wrench (in the illustrated example) is inserted into the square hole 12 a of the rotator 12 through the notch 28 of the holding plate 10. Then, when the square wrench is turned counterclockwise in FIG. 7, the rotator 12 turns counterclockwise.

With this movement, the protrusion 12b of the rotor 12
, In other words, the support pins 2
7, the up-and-down plate 13, which has been prevented from rotating counterclockwise in FIG. 7, is released from the action of the projection 12b, so that it can rotate counterclockwise. However, since the undulating plate 13 released from the rotation inhibiting action of the projection 12b is supported by the buffer spring 16,
It rotates only when a force opposing the spring pressure of the buffer spring 16 is applied from above.

After rotating the rotator 12 as described above, holding the blade support plate 7 and pressing it in the counterclockwise direction in FIG. 7, the blade 8 separates from the roll peripheral surface, and The lock plate 26 whose bottom surface has been in contact with the upper surface of the undulating plate 13 rotates while pushing the undulating plate 13 at the curved portions on both sides of the bottom surface, and the side surface of the lock plate 26 abuts or approaches the upper surface of the undulating plate 13. (See FIG. 8).

In this state, the blade 8 is far away from the roll peripheral surface, is maintained in a stable state, and can be cleaned. After the cleaning operation, the blade support plate 7 is pressed to rotate the scraper shaft 6 in the clockwise direction in FIG.
Is made to contact the upper surface of the undulating plate 13.

Then, a square wrench is inserted into the square hole 12a and is rotated clockwise in FIG. Thus, the undulating plate 13 is again pushed up by the projection 12b, and its lowering operation is prevented. That is, the scraper is locked.

The degree of buffering of the relief plate 13 by the buffer spring 16 can be adjusted by moving the adjusting bolt 22 forward and backward. Further, the contact pressure of the blade 8 against the roll peripheral surface can be adjusted by moving the adjustment bolt 21 forward and backward.

In a preferred embodiment, the blade 8 of the scraper is removed from the blade support plate 7 and made replaceable. 9 to 11 show a configuration example for this purpose. The blade 8 is usually made of a nylon resin, and has one or a plurality of dowel holes 31 extending in the thickness direction.

The blade support plate 7 has at its end a blade fitting portion 32 having a U-shaped cross section, and a dowel 3 at a position corresponding to the dowel hole 31 on the inner surface of one side surface of the blade fitting portion 32.
3 are protruded. The dowel 33 is fitted into the dowel hole 31 when the blade 8 is pushed into the blade fitting portion 32,
This prevents the blade 8 from coming off. In order to facilitate the fitting of the dowel 33 into the dowel hole 31, it is preferable to provide a guide groove 34 which communicates with the dowel hole 31 from the fitting end of the blade 8 and guides the dowel 33.

Preferably, a through hole 35 is formed at a position corresponding to the dowel 33 on the other side surface of the blade fitting portion 32. The through hole 35 communicates with the dowel hole 31, and when the blade 8 is removed, the dowel 33 is pushed out by inserting a thin rod therefrom, and the blade 8 can be easily pulled out.

[0025]

The present invention is as described above. In order to clean the scraper, the work of separating the blade from the roll peripheral surface can be easily performed by using a square wrench from the inner surface side of the side plate without removing the side plate cover and the like. Therefore, even if the frequency of cleaning increases, there is no need for labor, and there is an effect that the scraper can be cleaned easily and efficiently.

According to the second aspect of the present invention, the sharp rotation of the scraper is suppressed, so that the operation can be performed safely and the scraper is prevented from being damaged. Has the effect that the contact pressure of the blade against the roll peripheral surface can always be kept optimal.

According to the fourth aspect of the present invention, the movement of the scraper can be reliably locked by a simple operation. In the fifth aspect of the present invention, since the blade is replaceable, scraping of residue and the like can be performed. The dropping operation can always be performed satisfactorily, and parts can be replaced only when the blade is damaged, which is economical.
