The raw seaweed cutting machine can cut the raw seaweed accurately into a predetermined size, and the cutting edge can be straightened to avoid quality degradation of the raw seaweed. About.

  In a conventional raw seaweed cutting machine, cutting the raw seaweed accurately and straightening the cut edge avoids the quality deterioration of the raw seaweed, and avoids the quality deterioration of the raw seaweed, for example, dry seaweed It is desired to improve the luster, texture, or relative quality. However, in reality, the gap between the perforated plate and the knife is constant (the knife is in contact with the perforated plate at a predetermined pressure). When the gap is constant as described above, 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 it cannot be changed depending on the transport speed of laver, the following problems occur. 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, in this raw seaweed cutting device, it is essential to cut the raw seaweed accurately and to cut the cutting edge of the cutting with a straight line. List inventions.

  Document (1) is a “raw seaweed cutting machine” disclosed in Japanese Patent Application Laid-Open No. 7-250656. In this invention, a plate is loosely fitted on a rotary shaft provided in a plate chamber of a main body, and a knife is slid onto the plate. The knife is attached to the rotating shaft only in the rotating direction, and an elastic cylinder (urethane rubber cylinder) that presses the knife is interposed on the rotating shaft, and the knife is plated through the urethane rubber cylinder. It is characterized by being slidably elastically contacted with a uniform pressure. This urethane rubber cylinder is designed to press the knife toward the plate side to make the raw nori cut evenly, and when the knife is worn, it is impossible to avoid the extreme deterioration of the raw nori cut. It is intended to effectively use the elastic force of the urethane rubber cylinder so that no external force is applied.

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.

  Accordingly, the tightening state of the retaining ring 10 that presses the perforated plate 20 against the inner knife 4 is approximately 1/4 rotation (for example, a gap of 1.0 mm) with the scale needle 21 as the zero point of the scale plate 22. Is assumed to be loosened in 10 steps, and the numerical value of the scale plate 22 is set to 0 to 10. Therefore, the clearance between the perforated plate 20 and the knife 4 is determined by returning the fixing screw 14, rotating the press ring 10, and adjusting the scale needle 21 to a desired value of the scale plate 22. As a result, the pressing force of the knife 4 against the raw laver is adjusted (the pressing force against the knife 4 is constant). After this adjustment, the pressing force is determined by tightening the fixing screw 14. Therefore, unless the unscrewing and / or tightening of the fixing screw 14 and the pressing ring 10 are rotated, the gap is constant and the pressing force against the knife 4 is also constant. Since the press ring 10 is engaged with the spur gear by the screw 11 and the screw 12 and moved by the spur gear, the clearance / movement and / or the pressing force can be reliably adjusted. Cutting is performed while the raw laver sent out by the extrusion screw 2 with this predetermined pressing force is gently moved on the surface of the porous plate 20 while being held by the knife 4, for example, physical properties of the raw laver and The raw laver cutting operation is performed in an optimum state in accordance with various conditions.
