[0001] The utility model relates to the field of slitter blades, in particular to a novel carbide-coated slitter blade. Background Art

[0002] A slitter blade is a cutting tool used on a slitting machine (such as a slitter) to cut raw materials (such as paper, plastic film, etc.) into required sizes or shapes. Slitter blades are usually made of high-hardness alloy steel or tool steel and have excellent wear resistance and cutting performance.

[0003] Although the current slitter blades can increase their hardness through carbide coating, there is still a possibility of damage. And since they are of an integral structure, when the blade is damaged, the whole blade needs to be replaced, which is rather wasteful.

[0004] Therefore, it is necessary to invent a novel carbide-coated slitter blade. Content of the Utility Model

[0005] For this reason, the utility model provides a novel carbide-coated slitter blade to solve the problem that although the current slitter blades can increase their hardness through carbide coating, there is still a possibility of damage. And since they are of an integral structure, when the blade is damaged, the whole blade needs to be replaced, which is rather wasteful.

[0006] To achieve the above object, the utility model provides the following technical solution: A novel carbide-coated slitter blade, including a tool shaft, on the surface of which a number of tool seats are evenly fixed. It also includes a number of blades corresponding to the tool seats. A carbide coating is provided on the surface of the blade. The blade is composed of a first half blade and a second half blade which are symmetrically arranged. The first half blade and the second half blade are detachably installed on the corresponding tool seats through a first connection component, and the first half blade and the second half blade are detachably installed through a second connection component.

[0007] Preferably, the first connection component includes a first half-ring connecting piece and a second half-ring connecting piece. The first half-ring connecting piece is fixed in the middle of the first half blade, and the second half-ring connecting piece is fixed in the middle of the second half blade. The ends of the first half-ring connecting piece and the second half-ring connecting piece are in contact with each other.

[0008] Preferably, threaded holes are provided in the middle of both the first half-ring connecting piece and the second half-ring connecting piece, and fixing screws are threadedly connected to the inner walls of the threaded holes.

[0009] Preferably, threaded grooves are symmetrically provided in the tool seat, and the opposite ends of the two fixing screws are respectively threadedly connected in the two threaded grooves.

[0010] Preferably, the second connection component includes a plurality of first connection rows and a plurality of second connection rows. The plurality of first connection rows are symmetrically fixed on the first half blade, and the plurality of second connection rows are symmetrically fixed on the second half blade. The plurality of first connection rows and the plurality of second connection rows correspond to each other one by one.

[0011] Preferably, connection holes are formed at the centers of the first connection row and the second connection row. Fixing bolts penetrate between the two corresponding connection holes, and matching nuts are threadedly connected to the ends of the fixing bolts.

[0012] The beneficial effects of the present utility model are as follows: Through the combined use of the tool shaft, tool holder, blade, first connection component and second connection component, first, the blade is divided into two half blades. In this way, when any one of the half blades is damaged, only the damaged half blade needs to be replaced, without the need for overall replacement, thus effectively avoiding waste and saving costs.

[0020] Please refer to the attached Figures 1-5, a novel cutting machine blade with a cemented carbide coating provided by the present utility model includes a tool shaft 1, and a plurality of tool holders 2 are evenly fixed on the surface of the tool shaft 1. It further includes a plurality of blades 3 corresponding to the plurality of tool holders 2. A cemented carbide coating 4 is provided on the surface of the blade 3. The cemented carbide coating 4 is a well-known technology to those skilled in the art and will not be elaborated further. The blade 3 is composed of a first half blade 31 and a second half blade 32 which are symmetrically arranged. That is, the novel cutting machine blade can be set to a structure that is divided into two parts and assembled by two half blade structures. The first half blade 31 and the second half blade 32 are detachably installed on the corresponding tool holder 2 through a first connection component, and the first half blade 31 and the second half blade 32 are detachably installed through a second connection component;

[0021] The first connection component includes a first half-ring connecting piece 311 and a second half-ring connecting piece 321. The first half-ring connecting piece 311 is fixed in the middle of the first half blade 31, and the second half-ring connecting piece 321 is fixed in the middle of the second half blade 32. The ends of the first half-ring connecting piece 311 and the second half-ring connecting piece 321 are fitted together. Threaded holes 5 are opened in the middle of both the first half-ring connecting piece 311 and the second half-ring connecting piece 321. Fixing screws 6 are threadedly connected to the inner walls of the threaded holes 5. Threaded grooves 7 are symmetrically opened on the tool holder 2. The opposite ends of the two fixing screws 6 are respectively threadedly connected into the two threaded grooves 7. Specifically, under the action of the two fixing screws 6, the first half-ring connecting piece 311 and the second half-ring connecting piece 321 can be fixed on the tool holder 2, thereby fixing the first half-ring connecting piece 311 and the second half-ring connecting piece 321 on the tool holder 2. Similarly, by reverse operation, the first half-ring connecting piece 311 and the second half-ring connecting piece 321 can be detached from the tool holder 2, enabling the blade 3 and the tool holder 2 to be conveniently disassembled and assembled, thus facilitating subsequent replacement and maintenance operations;

Matching nuts 10 are threadedly connected to the ends of the fixing bolts 9. Specifically, under the fixing action of the fixing bolts 9 and the matching nuts 10, the corresponding first connection row 312 and the second connection row 322 can be fixedly connected, thereby fixedly connecting the first half blade 31 and the second half blade 32, that is, assembling the blade 3 that is divided into two parts. Similarly, by reverse operation, the first half blade 31 and the second half blade 32 can be disassembled. That is, when any half blade is damaged, only the damaged half blade needs to be replaced, without the need to replace the whole, effectively avoiding waste and saving costs.

[0023] The working principle of the present utility model is as follows: First, under the fixing action of the fixing bolt 9 and the matching nut 10, the corresponding first connecting row 312 and the second connecting row 322 can be fixedly connected, thereby fixedly connecting the first half blade 31 and the second half blade 32, that is, assembling the split blade 3. Similarly, by operating in the reverse direction, the first half blade 31 and the second half blade 32 can be disassembled. That is, when any half blade is damaged, only the damaged half blade needs to be replaced, without the need to replace the whole, thus effectively avoiding waste and saving costs.

[0024] Secondly, under the action of the two fixing screws 6, the first half-ring connecting piece 311 and the second half-ring connecting piece 321 can be fixed on the tool holder 2, thereby fixing the first half-ring connecting piece 311 and the second half-ring connecting piece 321 on the tool holder 2. Similarly, by operating in the reverse direction, the first half-ring connecting piece 311 and the second half-ring connecting piece 321 can be disassembled from the tool holder 2, enabling the blade 3 and the tool holder 2 to be conveniently disassembled and assembled, thus facilitating subsequent replacement and maintenance operations.
