Description

Technical Field

[0001] The present invention relates to the technical field of blades, and in particular to a cutting blade and a processing and manufacturing method thereof. Background Art

[0002] The existing utility knife cannot cut through the bag in one go, and the blade needs to be replaced frequently, so it is not suitable to be installed in automated equipment for use. A general triangular blade becomes blunt after being worn to a certain extent. The force generated during the bag cutting process along the direction of blade movement can easily lift up the woven bag, making it impossible to cut through the woven bag. At the same time, a woven bag that cannot be effectively cut through can easily cause adhesion, making the material falling process uneven after the bag is broken. Some blades need to be replaced frequently, so it is not suitable to be installed in automated equipment for use. Summary of the invention

[0003] The object of the present invention is to provide a cutting blade and a manufacturing method thereof to solve the problems mentioned in the above background technology.

[0004] The technical solution of the present invention is a cutting blade, comprising a tool, wherein the tool comprises a long side, a short side is provided on one side of the long side, three fixing holes are opened on the long side, a cutting edge is opened on the top of the long side, an arc part is opened at the junction of the long side and the short side, and a sharp corner part is opened on the top of the short side.

[0005] In one embodiment, the tool adopts a cutting edge that combines a sharp corner and a circular arc. Compared with a single cutting edge, it is helpful to reduce the influence of the undulation of the woven bag on the bag breaking effect during the bag breaking process.

[0006] In one embodiment, the cutter can be applied to automated equipment to realize an automatic bag breaking process.

[0007] In one embodiment, the arc structure of the tool effectively changes the cutting force component so that it is consistent with the cutting direction, which is conducive to cutting and breaking the bag. It also reduces the influence of its force component on the position of the woven bag after the blade is worn, and the woven bag will not be lifted up during lateral movement.

[0008] In one embodiment, the two cutting edges act separately for different bag breaking processes, thereby effectively increasing the service life of the tool.

[0009] A method for manufacturing a cutting blade comprises the following steps:

[0010] S1: This tool is mainly used in automation equipment, suitable for straight or four-corner bag breaking, and multiple knives are used together;

[0011] S2: Taking the four-corner bag breaking as an example, the four cutters are arranged diagonally and are initially located at the center point. The comprehensive use process is mainly divided into two steps: ① When the cutter is at the center point, the material is placed on top, and the sharp corner of the cutter pierces the woven bag; ② The cutter moves to the four corners at the same time, and the arc part cuts the woven bag to achieve the bag breaking.

[0012] The beneficial effects provided by the present invention are:

[0013] The present invention can be applied to automated equipment to realize automatic bag breaking; the multi-edge structure is more conducive to bag breaking; compared with the adhesion of material bags caused by the blunt edges of general tools, the structure can be worn within a certain range without affecting the bag breaking effect, thereby indirectly increasing the service life of the tool.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The technical solution of the present invention will be further described below in conjunction with the drawings of the embodiments of the present invention, and the present invention is not limited to the following specific implementation methods.

[0019] It should be understood that the same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components. In the description of the present invention, it should be understood that if the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom" and the like indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] In one embodiment, Figure 1 , Figure 2 , Figure 3As shown, a cutting blade comprises a tool 1, the tool 1 comprises a long side 3, a short side 7 is provided on one side of the long side 3, three fixing holes 2 are provided on the long side 3, a cutting edge 4 is provided on the top of the long side 3, an arc portion 5 is provided at the junction of the long side 3 and the short side 7, and a sharp corner portion 6 is provided on the top of the short side 7;

[0021] The tool 1 adopts a cutting edge 4 in the form of a combination of a sharp angle and an arc. Compared with a single cutting edge 4, it is beneficial to reduce the influence of the fluctuation of the woven bag on the bag breaking effect during the bag breaking process. The tool 1 can be applied to automated equipment to realize the automatic bag breaking process. The arc structure of the tool 1 effectively changes the cutting force component to make it consistent with the cutting direction, which is beneficial to cutting and breaking the bag. At the same time, it also reduces the influence of the force component of the cutting edge 4 on the position of the woven bag after the cutting edge 4 is worn, and the woven bag will not be lifted up during the lateral movement. According to different processes of bag breaking, the two cutting edges 4 act separately, which effectively improves the service life of the tool 1;

[0022] Comprehensive use scenarios, using a combination of arc and straight line, the overall "L" shape as the outline, the long side 3 of the tool 1 is the installation side, leaving a fixing hole 2, the front end of the short side 7 is a sharp corner part 6, the rear end of the short side 7 is an arc part 5, the arc part 5 and the oblique side of the sharp corner part 6 intersect at one point, and are tangent to the long side 3;

[0023] The bag breaking process is mainly divided into piercing and transverse cutting. The sharp corner part 6 of the tool 1 is easy to pierce into the surface of the woven bag. The transverse cutting process mainly uses the arc part 5 for cutting. The arc part 5 can effectively change the cutting force to make it consistent with the cutting direction. At the same time, the arc part 5 can also be compatible with the ups and downs of the woven bag during the movement, thereby reducing the adhesion such as incomplete cutting caused by the detachment of the tool 1. Accordingly, cutting edges 4 are processed on the sides of the sharp corner part 6 and the arc part 5. Since the cutting force is consistent with the cutting direction, when the blade After the edge 4 becomes blunt due to a certain wear, it can still maintain a certain bag breaking effect, thereby increasing the life of the tool 1. The sharp corner part 6 is mainly used for piercing the bag, and the arc part 5 is mainly used for horizontal movement and scratching. The two cutting edges 4 act in steps, which also increases the service life of the tool 1 compared to the single cutting edge 4. The material of the tool 1 can be selected from high-speed steel, 45#, stainless steel, etc., and the sizes of the sharp corner part 6 and the arc part 5 can be adaptively adjusted according to the thickness of different material bags, so as to be more suitable for use; the tool 1 can also be installed in other ways, such as a splint.

[0025] S1: This tool 1 is mainly used in automation equipment, suitable for straight or four-corner bag breaking, and multiple knives are used together;

[0026] S2: Taking the four-corner bag breaking as an example, the four knives 1 are arranged diagonally and are initially located at the center point. The comprehensive use process is mainly divided into two steps: ① When the knife 1 is at the center point, the material is placed on the top, and the sharp corner part 6 of the knife 1 pierces the woven bag; ② The knife 1 moves to the four corners at the same time, and the arc part 5 cuts the woven bag to achieve the bag breaking.
