Automatic crab leg shell cutting-in machine

摘要

An automatic crab leg shell cutting-in machine for processing crabs' legs. In order to charge the cutting-in machine with crab legs at a predetermined processing rate, the upper and lower feed-belts are provided in the longitudinal direction of the machine. Rotary cutting-knives are arranged therebetween on the both sides of a cutting-in section and depressing plates serving to depress the upper and lower feed-belts are provided opposite each other in such a manner that the upper and lower feed-belts have an increased or decreased clearance therebetween in the cutting-in section depending upon the dimensional conditions of a crab leg to be processed. The depressing plates are held so as to be vertically displaced with the aid of resilient means or shock absorbing means, whereas the rotary cutting-knives are arranged so as to approach the longitudinal axis of the feed-belts or move away therefrom in cooperation with resilient means or shock absorbing means and bell cranks. Further guide-members having a U-shaped cross section are provided in front and behind the cutting-in section of the machine.
