Description
[ technical field ] A method for producing a semiconductor device
The invention relates to a crusher cutter shaft applied to a film crusher and a film crushing method.
[ background of the invention ]
The common film crusher in the market at present drives the movable cutter to rotate by the motor, and the film entering the feeding hole and the fixed cutter generate a cutting effect under the driving of the inertia force, so that the film is crushed and then recycled. Such as is the case with the following three published patents. For example patent No. 201120138314X, entitled rotary cutter for a film shredder, published as 2011.11.30. 2011201480385 entitled rotating knife of film crusher, bulletin date 2011.11.23. Patent No. 2014202379198, entitled film shredder, published as 2014.09.10.
The movable knife consists of a main shaft, a knife rest and a plurality of groups of blades. The blade is obliquely arranged for a straight knife, the cutting edge is linear, and the cutting edge is arranged to form a certain deflection angle with the central line of the main shaft, so that the cutting effect of a scissor type shearing process is obtained in the crushing process, and a better crushing effect is obtained on blanks with small thickness and large width, such as films.
Although the straight-cutter inclined installation has the advantages, the existing straight-cutter inclined installation has the following disadvantages:
firstly, relatively speaking, the straight knife is obliquely provided with a problem that the knife gap of the moving knife and the fixed knife is large. Because the cutting edges of the fixed cutters are parallel to the axis of the main shaft, and the fixed cutters are arranged on a circular surface with equal radius. In the three-dimensional space, when two end points of a straight line which is not parallel to the axis are intersected with the cylindrical surface, namely under the condition that the two end points of the movable knife and the fixed knife can be in gapless contact in the rotating process, a certain gap is formed between the middle of the straight line and the circular surface, namely a gap is formed between the middle of the movable knife and the fixed knife. When the deflection angle is larger, or the axial position between the two end points is longer, or the radius is smaller, the radial distance between the point on the straight line except the end points and the circular surface is larger.
Secondly, because the middle of the movable knife can have a gap with the fixed knife, the inclined installation of the straight knife can cause material clamping or efficiency reduction caused by enlarging the gap, because the material can be sheared along with the scissors of the knife edge in the crushing process, the material can axially slide and finally accumulate in the gap between the end face of the movable knife and the end face of the fixed flange of the frame to cause material clamping, and in addition, the processing method is to enlarge the gap between the movable knife and the end face baffle plate to cause low efficiency.
The present invention has been made under such circumstances.
