Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings.
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The nylon blade for the paper folding mechanism comprises a blade body 1, wherein the front end part of the blade body 1 is provided with a blade tip part 11, a connecting part 12 is further arranged between the blade tip part 11 and the blade body 1, and an included angle between the bottom surface of the blade tip part 11 and the bottom surface of the connecting part 12 is an obtuse angle.
Specifically, the edge portion 11 can fold the paper 4 into the gap of the chuck shaft 3, while the slope of the edge portion 11 of the original blade is unchanged, and after abrasion, the thickness of the edge portion 11 is too large to fold the paper into the gap of the chuck shaft 3. For the above reasons, the present utility model makes the thickness of the tip portion 11 slower by extending the length of the tip portion 11 and reducing the slope of the tip portion 11, thereby extending the workable length of the tip portion 11 and providing a grinding amount after later abrasion. Meanwhile, as the blade body 1 is matched with the folding roller 2, the thickness and the length of the rear end part of the blade body 1 are fixed, if the connecting part 12 is not arranged between the cutter point part 11 and the blade body 1, the thickness of the rear end part of the cutter point part 11 is a fixed value, and the gradient selection range of the cutter point part 11 is limited. By providing the connecting portion 12 between the edge portion 11 and the blade body 1, the thickness of the rear end portion of the edge portion 11 can be changed, and the slope selection range of the edge portion 11 can be increased. In order to provide a larger grinding amount, the slope of the tip portion 11 needs to be smaller, and the slope of the connecting portion 12 should be larger than that of the tip portion 11, so that the included angle between the bottom surface of the tip portion 11 and the bottom surface of the connecting portion 12 is an obtuse angle. Wherein the slope is based on the orientation shown in the drawings, and the slope is smaller, namely the thickening degree is smaller. In addition, select nylon as the blade material, based on the structural feature of nylon, when not damaging paper 4, can be convenient for blade body 1 get into the clearance of pressing from both sides paper axle 3.
As another specific embodiment, the top surfaces of the blade body 1, the nose portion 11, and the connecting portion 12 are coplanar. The working strength of the nylon blade can be ensured.
