Description

Technical Field

[0001] The utility model belongs to the technical field of blades and relates to a blade, in particular to a new blade. Background Art

[0002] A blade is a part of a tool, weapon or machine whose edge is designed to pierce, cut or scrape the surface of a material. In mechanical engineering terms, a blade refers to a sheet-like part mounted on a machine for cutting.

[0003] In the existing blade, once the blade is damaged, the entire blade needs to be replaced. However, the blade is usually damaged at only one or two locations, and the entire blade cannot be used any more, resulting in great waste. Summary of the invention

[0004] The utility model aims to provide a new blade which can improve processing efficiency and reduce use cost in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new blade, characterized in that it includes a plurality of blade assemblies, and the plurality of blade assemblies form a blade as a whole for working, the blade assembly includes a fixed frame and a blade, the upper and lower ends of the fixed frame are fixedly provided with connecting parts, and the connecting part and the fixed frame are integrally formed, the fixed frame is provided with a plurality of mounting parts for installing the blade, the fixed frame has a chip removal space for chip removal, each of the blade assemblies is fixedly provided with a fixing ring for connecting the upper and lower blade assemblies relative to the connecting part, and the fixing ring and the fixing part are integrally formed, and the fixing ring and the fixed frame are both provided with an axial hole for the transmission shaft to be sleeved.

[0006] In the above-mentioned new blade, two adjacent blade assemblies are installed by fixing bolts, wherein a fixing ring of one blade assembly arranged at the lower end is connected to a fixing ring of another blade assembly arranged at the upper end, thereby forming the two blade assemblies into a whole blade.

[0007] In the above-mentioned novel blade, a mounting hole for mounting is provided on the fixing ring.

[0008] In the above-mentioned novel blade, the blade is detachably fixedly mounted on the mounting portion.

[0009] In the above-mentioned novel blade, the mounting portion and the blade are arranged on the fixed frame in a spiral structure.

[0010] Compared with the prior art, the new blade is composed of multiple blade components to form a blade as a whole. When one of the blade components is damaged, it can be replaced individually without replacing the entire blade as a whole, thereby reducing the cost of use. In addition, it has a chip removal space inside for chip removal, which is convenient for operators to clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the utility model.

[0012] Figure 2 It is a structural schematic diagram of a single blade assembly in the utility model.

[0013] In the figure, 1. blade assembly; 2. blade as a whole; 3. fixed frame; 4. blade; 5. connecting part; 6. mounting part; 7. chip removal space; 8. fixing ring; 9. shaft hole; 10. mounting hole. DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 As shown, the new blade includes several blade assemblies 1. The blade assemblies 1 can process multiple products at the same time, which greatly improves the processing efficiency of the products. Several blade assemblies 1 form a blade 4 as a whole 2 for working. The blade assembly 1 includes a fixed skeleton 3 and a blade 4. The upper and lower ends of the fixed skeleton 3 are fixedly provided with connecting parts 5, and the connecting part 5 and the fixed skeleton 3 are integrally formed. The fixed skeleton 3 is provided with several mounting parts 6 for installing the blade 4. The fixed skeleton 3 has a chip removal space 7 for chip removal inside. The chip removal space 7 is convenient for the operator to clean up the waste chips generated by the processing to avoid affecting the work of the blade 4. A fixing ring 8 for connecting the upper and lower blade assemblies 1 is fixedly provided on each of the blade assemblies 1 and relative to the connecting part 5, and the fixing ring 8 is integrally formed with the fixing part. The fixing ring 8 and the fixed skeleton 3 are both provided with an axial hole 9 for the transmission shaft sleeve.

[0016] To elaborate further, the two adjacent blade assemblies 1 are installed by fixing bolts, wherein a fixing ring 8 provided at the lower end of one blade assembly 1 is connected to a fixing ring 8 provided at the upper end of the other blade assembly 1 so as to form a blade 4 integral body 2 with the two blade assemblies 1.

[0017] To elaborate further, after long-term operation, if the blade 4 on one of the blade assemblies 1 is damaged, one blade assembly 1 can be disassembled from the blade 4 as a whole 2 for replacement or repair. After it is disassembled, it does not affect the operation of the subsequent blade assembly 1, thereby improving the processing efficiency.

[0018] Preferably, a mounting hole 10 for mounting is provided on the fixing ring 8 .

[0019] Preferably, the blade 4 is detachably fixedly mounted on the mounting portion 6 .

[0020] Preferably, the mounting portion 6 and the blade 4 are arranged on the fixed frame 3 in a spiral structure.

[0021] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although the terms such as blade assembly 1, blade assembly 2, fixed frame 3, blade 4, connecting portion 5, mounting portion 6, chip removal space 7, fixed ring 8, shaft hole 9, mounting hole 10 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
