Description

  The present invention relates to a retaining ring of a raw seaweed cutting machine, the details are to cut the raw seaweed accurately and to a predetermined size, and to straighten the cutting cut, to make the cutting amount of raw seaweed constant, It relates to a retaining ring for a raw seaweed cutting machine that improves quality.

  In a conventional raw seaweed cutting machine, in order to accurately cut raw seaweed, a rotary knife is appropriately pressed against the perforated plate, and the pressure contact is achieved by using a screw nut (retaining ring) on the outer surface of the perforated plate. ) Tightening. The tightening is performed with an appropriate force based on the experience of the operator. The tightening force may be a constant and moderate pressure, but in some cases, the tightening force may be slightly released from this pressure (returning the retaining ring). And this tightening force is, for example, the physical properties of the raw nori (hardness, thickness, sampling time, raw nori part, etc.), the amount of raw nori in the housing (casing), or the raw nori in the housing Since the speed is individually changed depending on the conveyance speed or the like, a problem occurs if the tightening is not accurately performed. That is, the raw laver is shredded or excessively kneaded between the perforated plate and the knife, and as a result, the quality of the raw laver discharged from the housing is deteriorated. There may be harmful effects such as loss of gloss, occurrence of shrinkage, deterioration of texture, and generation of roughness on the surface of dry seaweed.

  Therefore, since the invention related to the retaining ring of this raw seaweed cutting device and the prior literature were investigated, these documents are listed.

  Document (1) is a “fresh seaweed continuous cutting device” disclosed in Japanese Patent Application Laid-Open No. 10-4932. The present invention provides chopper means in the housing of the main body, and the chopper means has a required number of through holes. The chopper plate provided and the blades project radially, and the chopper blade is provided with a predetermined gap, and the raw seaweed extruded by the spiral feed blades is finely cut by the chopper blade and the chopper plate. , Extruded from the through hole in the direction of the discharge port. At this time, foreign matter such as net yarn, fishing line, etc., which is stronger than the raw seaweed, is pulled in the rotation direction of the chopper blade while entering the gap without being cut when it hits the blade piece of the chopper blade. It is intended to efficiently collect the foreign matter.

  Further, Document (2) is “Non-parasite separation and cutting method and cutting apparatus for raw seaweed” disclosed in JP-A-2005-224216. This invention includes a fixing plate provided on a cylindrical casing, A rotary knife is provided on the lower side, and this rotary knife is fixed together with a rotary plate on a rotary shaft suspended from a cylindrical housing. The rotating plate is fixed to the rotating shaft via a washer and a key, but can be moved in the vertical direction by changing the thickness of the washer. However, this rotary knife is not a structure that can move in the vertical direction. Therefore, the sliding contact between the fixed plate and the rotary knife is a constant condition.

It is a top view of an example attached to.

  As shown in FIG. 1, reference numeral 1 denotes a substantially cylindrical housing provided in raw laver equipment such as a raw laver hybrid machine, a laver washing machine, etc. In this housing 1, a first rotating screw 2 which will be described later is rotated. A rotating shaft 3 and a second rotating shaft 5 for rotating the knife 4 are provided. The first and second rotating shafts 3 and 5 have a biaxial structure. The first rotating shaft 3 and the second rotating shaft 5 are rotatably supported by the housing 1 and the first rotating shaft 3 via bearings 6 and 7, respectively. Pulleys 8 and 9 are fixed to the first and second rotary shafts 3 and 5, and the pulleys 8 and 9 are rotated at predetermined intervals via a driving unit such as a motor or a variable speed motor (not shown). Rotated by number. This rotation is transmitted to the first and second rotary shafts 3 and 5 so that the extrusion screw 2 fixed to the first and second rotary shafts 3 and 5 and the knife 4 are rotated at a predetermined rotational speed. Rotate with. 15 is a drainage means provided substantially in the middle of the axial direction [arrow “I”] of the housing 1, and this drainage means 15 discharges excess water and / or laver potatoes existing in the housing 1. Reference numeral 25 denotes a raw seaweed inlet, and 26 denotes a raw seaweed outlet.

  And this knife 4 has various forms (the number of blades, a size, and a shape), for example, is comprised like the cross shape which provided the blade part in the cross shape, the radial shape etc. which provided the blade part in the square shape, etc. . In other words, the shape is formed by a person when viewed from the front. The knife 4 is provided perpendicular to the second rotating shaft 5. The knife 4 is secured to the second rotary shaft 5 and rotates in the same manner as the extrusion screw 2 (details will be described later). In addition, the form of the knife 4 is suitably changed according to the physical properties of raw nori.

  50 is a perforated plate provided on the first rotary shaft 3, and the knife 4 is slidably rotated on the perforated plate 50. The raw laver that is conveyed toward the open side 1a of the housing 1 is cut into a predetermined length by the extrusion screw 2 through the sliding contact rotation between the perforated plate 20 and the knife 4. At the time of this cutting, depending on the physical properties of the raw nori, by cutting the raw nori while cutting it, or cutting it while squeezing with a knife 4, for example, securing the gloss of the finished surface of the dry nori, There are features such as the ability to eliminate roughness and the reduction of perforations in fresh seaweed. Then, by changing the rotation ratio between the extrusion screw 2 and the knife 4, for example, the feed amount of the raw nori, the cutting time of the knife 4, and / or the kneading time (movement time) of the raw nori are appropriately changed. In this way, adaptation to the physical properties of fresh seaweed, adjustment of the cutting method of fresh seaweed, securing of the quality of dry seaweed, etc. are attempted. The perforated plate 50 is provided with a retaining nut 27 so as to be detachable with respect to the second rotating shaft 5 at the center thereof. When the perforated plate 52 is attached or detached, the retaining nut 27 is removed or removed. It shall be installed.

  As shown in FIG. 4, the retaining ring 10 is provided with a plurality of convex portions 100 at an appropriate interval over the circumference thereof. An operator, a manager, etc. hold the convex portion 100 and rotate the retaining ring 10 to adjust the gap between the perforated plate 50 and the knife 4. In addition, although mentioned later for details, the surface pressure adjustment means 20 is provided in one side 100b of this convex part 100, and the reverse return lock mechanism 40 is further provided in the other 100c.

  First, the surface pressure adjusting means 20 will be described. A hole 21 provided from the convex portion 100 of the retaining ring 10 toward the center of the housing 1, an adjustment screw 22 inserted into the hole 21, a spring 23 for flexibly mounting the adjustment screw 22, and the spring 23 And a ball 24 provided on the center side of the adjusting screw 22. Accordingly, the ball 24 which is located on the bottom surface of the hole 21 through the adjusting screw 22 and / or the spring 23 and is pressed by the concave portion 100e formed in the retaining ring 10 and pushed into the concave portion 100e of the retaining ring 10. Is a structure in which a constant surface pressure is applied to the perforated plate 50 and the knife 4 by separating from the retaining ring 10 when a certain tightening force is exceeded. A screw 11 provided on the inner peripheral surface of the retaining ring 10 and a screw 12 provided on the housing 1 are provided, and the screw 11 and the screw 12 meshing with the screw 11 can be moved. The retaining ring 10 can be reciprocated to the open side 1a of the housing 1. And in this movable state, the pitch and / or tooth profile of this screw 11 and screw 12 are set. This pitch secures the moving distance, and this tooth profile is useful for determining the moving position and / or securing the fixed state (preventing rattling during operation). And by adopting this structure, the cutting operation of the raw nori in the optimum state is performed in accordance with the physical properties of the raw nori and / or various conditions. In addition, the feed amount of raw nori can be controlled by time by the various adjustments and / or controls described above, and the stagnation time in the stagnation action of raw nori can be adjusted as described above.

  Further, the surface pressure adjustment in the surface pressure adjusting means 20 will be described. If it is desired to change to a desired surface pressure according to various conditions such as the physical properties (hardness, length, width, etc.) of raw seaweed and / or the sharpness of the knife 4, the adjusting screw 22 is screwed or screwed. By returning, the pressing force of the adjusting screw 22 is adjusted, and the surface pressure is adjusted. Note that the conventional adjustment range (pressure range) of the surface pressure is performed by rotating the adjusting screw 22 once. With this method, the adjustment range is limited, and it may not be possible to change to a desired surface pressure. In addition, 22a is a fixing screw and is provided for preventing rattling of the adjusting screw 22. In addition, 22b is provided with a groove used when the fixing screw 22a is screwed in, and the fixing screw 22a is screwed in and the adjusting screw 22 is pressed down.

Next, the reverse lock mechanism 40 will be described. As described above, since the ball 24 of the surface pressure adjusting means 20 is separated from the recess 100e and idles in order to keep the pressing force constant as described above, the sharpness of the knife 4 is improved. When the retaining ring 10 is removed due to, for example, replacement of the knife 4 in the case of deterioration, pressure is generated in the housing 1, and even if the retaining ring 10 is reversed, slipping occurs at the same pressure. Therefore, there may be situations where it cannot be removed. In order to improve the situation, the reverse lock mechanism 40 is required in this structure. An example of the reverse lock mechanism 40 will be described with reference to FIG. 5. When the retaining ring 10 is loosened , the roller lock 42 is disposed in an inclined groove 42 a provided to surround the roller lock 42. Move in the direction away (arrow "B") and slip. On the contrary, when this retaining ring is tightened , the roller lock 42 moves in the locking direction (the direction of the arrow “c”), bites into the wedge portion provided in the inclined groove 42a, is locked, and the retaining ring. It becomes the structure which can loosen 10. Reference numeral 42b denotes a spring (auxiliary tool) for pressing the roller lock 42 so as not to cause reluctance.

  Other examples of the reverse lock mechanism 40 include a ratchet mechanism, a ball lock mechanism, and the like (not shown), which are used as effective means for performing reverse lock. And if the position of this reverse lock mechanism 40 is provided in the convex part 100, the installation or number in the installation is arbitrary.
