Description

Gap adjusting device

Technical Field

Therefore, the shredder gate clearance must be calibrated periodically.

At present, a color coating method is generally adopted for measurement and setting: firstly, printing out a paper dividing disc (the paper dividing disc is divided into circles by a plurality of dividing lines, a certain included angle is formed between the two dividing lines), then manually cutting out a round hole in the center of the disc body so as to sleeve the round hole at the end shaft end of the screw rod, fixing the disc body on a frame by using an adhesive tape, and pulling the screw rod clockwise or anticlockwise by using a spanner so that the screw rod (the reference numeral "1" in fig. 1) is close to or far from the frame (the reference numeral "3" in fig. 1). When the screw is wrenched, the feeding amount or the retreating amount of the screw is judged by carefully observing the rotating angle of the screw, so that the aim of adjusting the size of a gap (namely a cutter gate gap) between the cutter roller bracket (reference numeral 2 in fig. 1) and the frame is fulfilled.
