Example 1

Combine the attached drawing, the utility model provides a cutter that cuts mechanism, including wavy cutting edge 2 and blade 1, in this embodiment, as an optimal scheme, with cutting edge 2 and blade 1 design as an organic whole, it adopts the forging and pressing technique to form the cross-section for 2 shaping of conical wavy cutting edge with 2 partial processing of cutting edge. Therefore, the thickness of the blade 2 of this embodiment is gradually increased from the conical tip 21 (the thickness of the conical tip 21 is less than 1 mm) to the conical bottom (greater than 4 mm), so as to effectively enhance the integrity of the blade 2 and the structural strength thereof, and thus, the blade can be suitable for cutting materials such as woven bags and non-woven fabrics. In order to realize hot cutting, a heating hole 13 for installing a heating element is formed in the junction of the blade 2 and the blade 1, the axial direction of the heating hole 13 is parallel to the wave shape of the blade 2 or is arranged in a relatively inclined manner, and the blade 1 is communicated with the heating hole 13 from left to right.

In this embodiment, the bottom of blade 1 sets up the mounting hole and is used for connecting, can separate the certain distance with heating hole 13 place on the one hand, avoids the two distance too closely to lead to structural stability to be destroyed, and on the other hand, blade 1 bottom has great space, will install the mounting hole setting in blade 1 bottom can not occupy the space of blade 1 side, establishes the basis for the length of reducing blade 1 side, the height of cutter itself. In addition, since the bottom space of the blade body 1 is large, the number of mounting holes can be further increased to improve the connection strength or mounting strength when the cutter is connected or mounted to another member. The mounting holes in this embodiment are preferably threaded to the attachment holes 14 for ease of machining, as well as ease of installation and removal.

When in use, the heating element is inserted into the opening of the heating hole 13 on either side of the knife body 1 to complete the installation. And since the present embodiment provides the heating hole 13 at a position between the blade body 1 and the blade body 1, the heat transfer efficiency is improved by shortening the heat transfer path.

Of course, in the above embodiment, in order to maintain the blade 2 with a large thickness, the taper angle at the taper point 21 of the tapered section of the blade 2 is preferably not less than 20 °, and may be in a range of 25 to 40 ° as a generally used range. In the above structure, the thickness of the wavy blade 2 is greatly increased by designing the blade 2 to be tapered, thereby enhancing the strength of the blade 2, and in the case where the thickness thereof is thick, the tapered tip 21 can be processed to a thickness of 0.05mm at a minimum to have a higher sharpness.

In addition, in order to further reduce the volume of the cutter of the embodiment, the distance between the conical tip 21 and the bottom of the cutter body 1 can be controlled to be 4-25 mm, and in the range, the general use requirements can be met, the volume can be reduced, and the space occupied by the cutter can be reduced. In order to avoid the heating hole 13 from causing excessive influences on the structural stability and structural strength of the cutter as much as possible, and further cause the cutter to be unusable, the aperture of the heating hole 13 needs to be limited, and the aperture is controlled to be not more than 1/4 from the conical tip 21 to the bottom height of the cutter body 1 and/or to be more than the width of the cutter body 1 of 1/2 and to be less than the width of the middle part of the conical tip, so that the integrity and the structural stability of the cutter can be ensured.

Of course, since the blade 1 and the blade 2 are integrally formed in embodiment 1, the transition portion 11 and the mounting portion 12 are also integrally formed in this embodiment.

The heating hole 13 is provided between the blade 1 and the blade 2 based on embodiment 1, and in this embodiment, the heating hole 13 is provided at the border between the transition portion 11 and the mounting portion 12. As a further means for improving the heat transfer efficiency, the axis of the heating hole 13 may be located in the transition portion 11 so that the heating hole 13 is closer to the blade 2, and heat can be transferred to the blade 2 in a shorter path. Meanwhile, in order to avoid the influence on the strength and stability of the blade 2 caused by the excessive approach of the heating hole 13 to the conical tip 21, the distance between the axis of the heating hole 13 and the bottom of the transition portion 11 needs to be limited to 0.02-0.1 mm, so that the heating hole 13 is not too inclined but arranged in the transition portion 11.

In the above embodiment, the number of the threaded connection holes 14 may be uniformly distributed at intervals of 10 to 30mm or other distances according to the length of the actual cutter, the aperture of the threaded connection hole 14 is preferably controlled to 1/5 to 1/4 of the width of the cutter body 1, and the length of the aperture of the threaded connection hole 14 is preferably greater than the height of the cutter body 1 of 1/2 and less than the height of the cutter body 1 of 2/3.
