Description

[Detailed explanation of the idea]

[Industrial Application Field] The present invention relates to a cutting blade for frozen meat, etc. [Prior art and its problems] Conventionally, the L is placed at any location on the cylindrical cutting blade mounting base.
A cutting blade for frozen meat, in which a cutting blade is mounted in a mold recess and fixed with a bolt, is known, but it has the following problems. (1) The contact area for fixing the cutting blade to the cutting blade mounting base was small, and the cutting blade became loose during cutting, forcing the interruption of cutting work, resulting in low cutting efficiency. (2) The gap between the cutting blade and the attachment/detachment part was clogged with meat, and there was no place for the meat to escape after cutting, so the cutting work was interrupted. (3) It was difficult to adjust the angle of the cutting edge for cutting allowance. [Purpose of the invention] The present invention has been made for the purpose of solving the problems (1) to (3) above. [Structure of the invention] The present invention has a cutting blade attachment/detachment part that has the width of the cutting blade and is a combination of an arcuate curve and a straight line, at any location in the cylindrical direction of the cylindrical cutting blade mount and in the width direction of the mount. This frozen meat cutting blade is made up of a plurality of blades each having double blades each having a cutout hole 7 having a shape substantially similar to the arcuate curve described above, each of which is attached to the attachment/detachment portion. [Example] An example of the present invention will be described below.
In FIG. 1, reference numeral 1 denotes a cylindrical cutting blade mount, and the mount is a welded cylindrical one. It may also be solid. The mounting base has a shaft hole 2 at the center of the shaft for mounting on a drive source. A cutting blade attachment/detachment portion for fixing a plurality of cutting blades is provided at any location in the circumferential direction and the width direction of this mounting base. The attachment/detachment part has an arbitrary cutting edge width and has a shape composed of an arcuate curve 4 and a straight line 5. This condition is a very important component of the present invention. This is important to eliminate looseness. Furthermore, the straight section is important for adjusting the thickness of the cut object. For example, if you want to cut a thin wall, just move the mounting position of the double-end blade to the right along a straight line and fix it, or if you want to cut a thick wall (the angle between the table and the blade is an obtuse angle), move it along a straight line. By moving to the left and fixing (the angle between the blade and the table becomes an acute angle), the cutting table can be adjusted easily and accurately, and the cutting blade can be firmly fixed. 6 is a screw hole for fixing the blades at both ends. On the cylindrical cutting blade mounting base having the above-mentioned shape, a hollow hole 7 is provided in the center of the double-end blade 3, which has a curved portion that is almost similar to the circular arc, to adjust the blade angle during installation. have. The cutting blade is fixed with a bolt 8 and a presser washer 9 at an arbitrary blade angle position.
Furthermore, there is a space 10 above the attached cutting blade, and the cut pieces of meat accumulate in this space and fall down as the table rotates, thereby preventing meat from clogging. [Effect of the invention] Mounting base: SUS304 270φ x 400 width Both ends blade: SKS quenched hardness 60°, blade thickness 7mm x width 20mm,
Nine pieces with a curve radius of 45R were fixed to the above-mentioned mount at arbitrary points in the circumferential direction and width direction, and this cutting blade was used to cut frozen meat pieces of 180 mm and 30 kg, which were obtained by multiplying the tooth width by 20 mm and the number of teeth by 9. The results are shown below.

【table】

[Table] As described above, when cutting frozen meat using the cutting blade of the present invention, it is a useful device that completely solves the problems (1) to (3) of conventional blades.
