Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cutting device mainly used for cutting cakes, breads, processed meat products, and seaweed sushi.

[Conventional technology]

Conventionally, cakes, breads, etc. have been cut using circular saws, band saws, or mechanical reciprocating devices as seen in Japanese Patent Publication No. 56-28678.

[Problem that the invention seeks to solve]

However, in the case of the former circular saw or band saw, the cutting life of the ball cutting edge, which generates a lot of chips, is short and requires frequent polishing. In addition, the latter mechanical reciprocating type has a low frequency and has a structure that simply moves multiple parallel blades adjacent to each other in the same direction, so it can handle soft objects such as bread and cakes. When cutting, if the blade is reciprocating at a low frequency, the object will move with the blade, making it difficult to cut. There were complaints that sticky materials adhered to the blade, resulting in poor cutting performance.

[Means for solving problems]

This invention provides a plurality of blade frames having a plurality of blades arranged in parallel at required intervals in the thickness direction of the blades, a plurality of movable inner frames each having the blade frames removably attached thereto, and a movable A plurality of movable outer frames each having an inner frame that can vibrate freely in the length direction of the blades, and blades of each blade frame are arranged alternately and parallel to each other so that the movable outer frame can be oscillated in the length direction of the blades. A fixed frame that is movably supported, a fine movement device that vibrates the movable inner frame relative to the movable outer frame, and a rocking device that swings the movable outer frame relative to the fixed frame with mutually shifted phases? In this way, the above-mentioned conventional points have been solved.

[Effect]

When the swing f2e and the vibration device are activated, each movable outer frame swings at a relatively large width at a low speed with a mutually shifted phase, and the blades are rocked together with the movable inner frame, The movable inner frame moves at high speed in a relatively small width in response to the swinging of the outer frame, causing the blade to vibrate. When the blade is fed into the machine, the object to be cut is efficiently cut with a smooth and clean cut due to the oscillating action of the blade accompanied by high-speed micro-vibration.
