Description

Technical Field

[0001] The utility model relates to a cutting tool, in particular to a short-edge serrated blade for cutting traditional Chinese medicine decoction pieces. Background Art

[0002] Existing circular saw blades have the following tooth shapes: 1. Left and right teeth: Each saw tooth has a chamfer of 1 / 3, mainly used for sawing wood materials. The saw teeth are split left and right to form a saw kerf. 2. Vertical cutting teeth: The rake angle of the tooth shape is 15° - 13°, mainly used for cutting the vertical fibers of materials. 3. Dual-purpose teeth: Their forward-inclined surfaces are used for cross-cutting wood fibers. There are also conical teeth (used in the slot saw blades of panel saws. When sawing double-sided veneer artificial boards, the slot saw completes the bottom grooving process, and the main saw completes the sawing process of the board), flat teeth (used for sawing ordinary wood), trapezoidal teeth (used in combination with flat teeth, suitable for sawing double-sided veneer artificial boards), and so on.

[0003] Since most traditional Chinese medicines are fibrous materials with small bulk density and various shapes, the above saw blades are not suitable for cutting traditional Chinese medicines. Most traditional Chinese medicines are manually cut with a chopping knife. Currently, there is no cutting blade dedicated to traditional Chinese medicine decoction pieces, nor is it convenient to be installed on a cutting machine to realize the automation of cutting traditional Chinese medicine decoction pieces. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a short-edge serrated blade, aiming to enable the blade to form a cutting effect of splitting, chopping, and pulling on traditional Chinese medicine decoction pieces when the blade is translated and rotated, with the characteristics of non-material curling and non-knife jamming, and capable of forming continuous cutting.

[0005] The purpose of the utility model is achieved as follows:

[0006] A short-edge serrated blade, in which a disc body is integrally cut to form solid teeth adjacent to each other front and back. The shape of each tooth is a pentahedron: in the triangle, 9° ≤ ∠A ≤ 64°, 50° ≤ ∠B ≤ 99°. The back of the triangle is parallel and similar to the front of the triangle and is larger than the front of the triangle. The included angle between the top surface of the quadrilateral and the back of the triangle forms a cutting edge (6). And in the top surface of the quadrilateral, the cutting edge line is parallel to the side corresponding to ∠B in the front of the triangle. The bottom surface and the back are respectively a quadrilateral bottom surface and a quadrilateral back surface.

[0007] The quadrilateral back surface is perpendicular to the top surface of the quadrilateral, and the intersection line of the quadrilateral back surface and the top surface of the quadrilateral is perpendicular to the cutting edge line in the top surface of the quadrilateral.

[0008] The degree of the cutting edge (6) is 15° - 60°, the number of teeth is 16 - 24, and the thickness of the teeth, that is, the thickness of the disc, is 0.5 mm - 5 mm.

[0009] The outer diameter of the disc body is 60 mm, the number of teeth is 20, the thickness T of each tooth is 2 mm, and the degree of the cutting edge is 45 degrees.

[0010] When the blade is cutting, the Chinese herbal medicine pieces are placed between the lower blade seat (2), the upper pressing plate (3) and the side baffle (4), and the blade teeth perform translational and rotational cutting of the Chinese herbal medicine pieces located below the cutting edge along the cutting edge root toward the cutting edge tip.

[0011] Compared with the prior art, the utility model has the following technical features and advantages:

[0012] 1. Special cutting method: The long side of the saw teeth on the blade forms a cutting edge. When rotating, the cutting edge forms a chopping, cutting, and pulling cutting action on the cut material. If the cutting edge of this tooth fails to cut the material, it will not take the material away, but the next tooth blade will continue to cut, thus forming a continuous cutting action until the cut material is cut, thus achieving a good cutting effect.

[0013] 2. Advanced cutting method: The existing blades on the market basically use grinding, smashing and bumping as cutting methods, and are often unable to cut tougher materials. This blade effectively achieves the cutting of tougher materials by changing the cutting method of the blade.

[0014] 3. No material rolling and knife blocking: Since the blade cuts the material continuously, the material will not be rolled away, causing material blocking and knife blocking.

[0015] The blade of the utility model is particularly suitable for cutting Chinese herbal medicine pieces, and is particularly suitable for cutting flexible filamentary materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 Figure 2 Figure 3 Figure 6Shown is a short-edge serrated blade. The disc body is integrally cut to form solid teeth that are adjacent to each other front and back. The shape of each tooth is a pentahedron: in the triangle at the front, 9° ≤ ∠A ≤ 64° and 50° ≤ ∠B ≤ 99°. The triangle at the back is parallel and similar to the triangle at the front and is larger than the triangle at the front. The included angle between the quadrilateral top surface and the triangle at the back forms the cutting edge (6). In the quadrilateral top surface, the cutting edge line is parallel to the side corresponding to ∠B in the triangle at the front. The bottom surface and the back surface are respectively a quadrilateral bottom surface and a quadrilateral back surface. The triangle at the front and the triangle at the back are coplanar with the surface and the bottom surface of the disc body respectively (the quadrilateral back surface is determined with the tip of the cutting edge as the front). The quadrilateral back surface is perpendicular to the quadrilateral top surface, and the intersection line of the quadrilateral back surface and the quadrilateral top surface is perpendicular to the cutting edge line in the quadrilateral top surface. The degree of the cutting edge (6) is 15° to 60°, the number of teeth is 16 to 24, and the thickness of the teeth, i.e., the thickness of the disc, is 0.5 mm to 5 mm. The outer diameter of the disc body is 60 mm, the number of teeth is 20, the thickness T of each tooth is 2 mm, and the degree of the cutting edge is 45 degrees. See Figure 4 Figure 5 , when the blade cuts, the traditional Chinese medicine slices are placed between the lower knife holder (2), the upper pressing plate (3), and the side baffle (4). The teeth of the blade perform a translational and rotational cutting on the traditional Chinese medicine slices located below its cutting edge along the root of the cutting edge towards the tip of the cutting edge.

[0021] Working process:

[0022] The motor or transmission device drives the blade to rotate. The cutting edge on the blade forms cutting actions of splitting, chopping, and pulling on the material to be cut, especially Chinese herbal medicine materials. If a tooth edge fails to cut through the material, it will not carry away the material either. Instead, the next tooth edge continues to cut, thus forming a continuous cutting action until the material to be cut is completely cut.
