1. The cut surface is concave
The concave surface of the paper is mainly caused by the following reasons: 1 The angle of inclination of the cutting knife is insufficient, and the cutting blade with a large inclination angle should be replaced; 2 The pressure of the jack is too low, and the pressure of the jack should be readjusted on the regulating valve; If the cutter holder is not in the proper position, the relevant screws should be re-examined and tightened.
2. Paper cracks
In general cutting, the cutting knife first comes into contact with the surface paper, then the paper is cut apart, and finally the lower layer of paper is cut. During the cutting process, the cutting surface of the paper stack will have the following phenomenon: the blade edge of the knife edge has not reached the paper cutting position, and the paper has cracks. This is because the pressure of the blade cutting causes the lower paper to break without waiting for the blade to reach. At this time, the crack is jagged. Usually, when the stack is cut to half the height, the crack starts to appear. The crack of the inner knife edge is smoothed by the plane rubbing on the back side of the knife, and the crack of the outer knife edge is relatively rough by the action of the 45° angled edge.
In addition, the reason why a part of the paper is cracked is that under the cutting force of the cutting blade, the instantaneous breaking strength of the paper is smaller than the breaking strength of the paper fiber, and under the action of the knife edge, the fiber at the edge of the paper edge is pulled out from the broken portion. This phenomenon is inevitable. The length of the paper crack and the size of the saw teeth are related to the pumping action and operating conditions of the paper cutter. (Editor: Liu Yidong)
Face-to-face Table Lifting Frame
A face to face desk stand is a desk design that usually consists of two tables and a middle stand so that two people can sit on either side of the table and work face to face. This design helps promote teamwork and communication, as two people can easily exchange ideas and discuss issues. Face to face table racks also save space because two people can share a table instead of needing two separate tables. In addition, face to face desk racks can also improve the efficiency of the office, as it can reduce the time for communication and coordination, making the team closer and more efficient.
