Technical Field

[0001] This utility model relates to the field of cross-cutting blade technology, specifically cross-cutting blades. Background Technology

[0002] A cross-cutting blade typically refers to a tool used for cutting materials horizontally. It is installed on a slitting machine or cross-cutting machine and can cut at high speed and with precision. A cross-cutting blade generally consists of two parts: the blade body and the cutting edge.

[0003] In existing cross-cutting blades, the blade body and cutting edge are generally connected by welding or integral molding. While this type of cross-cutting blade can meet the cutting requirements of materials, it still has the following shortcomings:

[0004] 1. When cutting hard materials, the blade wears out quickly and the cutting edge becomes dull easily, requiring frequent replacement of the cross-cutting blade, which increases costs;

[0005] 2. During high-speed or high-intensity cutting, friction between the blade and the material causes a rapid rise in temperature and generates heat. The blade will undergo thermal deformation at high temperatures, which will affect the cutting accuracy.

[0006] To address the aforementioned issues, a cross-cutting blade is now provided. Utility Model Content

[0007] The purpose of this invention is to provide a cross-cutting blade to solve the problems mentioned in the background art.

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] The present invention provides the following preferred embodiments:

[0035] Example 1, as Figures 1-8 As shown, the cross-cutting blade includes a blade body 11, a connecting mechanism, a cooling mechanism, and multiple blades 12;

[0036] Multiple blades 12 are arranged below the blade body 11, with the ends of every two blades 12 abutting each other.

[0037] By setting multiple segmented and detachable blades 12, when the cross-cutting blade is partially worn or dulled, the worn or dulled blades 12 can be disassembled and replaced individually without replacing the entire cross-cutting blade, which helps to reduce costs. At the same time, the detachable blades 12 allow the cross-cutting blade to select and replace blades 12 with appropriate blade angles according to the different hardness of the material to be cut, thus meeting different usage requirements.

[0038] The connecting mechanism includes a mounting component and a limiting component. The mounting component is used to mount the blade 12 onto the blade body 11 and is disposed between the blade body 11 and the plurality of blades 12. The limiting component is used to limit the blade 12 and is located at both ends of the blade body 11.

[0039] By setting a limiting component, the two blades 12 located at both ends can be limited, and multiple blades 12 can be stably installed below the blade body 11, preventing the blades 12 from sliding out of the end of the blade body 11 under the action of external force, and improving the connection effect between the blades 12 and the blade body 11.

[0040] The cooling mechanism includes multiple filling cavities 25 and multiple top covers 27, and each filling cavity 25 is filled with phase change material;

[0041] Phase change materials (PCMs) are substances that change their physical state and provide latent heat while maintaining a constant temperature. The process of changing physical properties is called a phase change process. During this process, PCMs absorb or release a large amount of latent heat. PCMs are existing technology and will not be elaborated on here.

[0042] Specifically, the phase change material in this application can be paraffin.

[0043] like Figures 1-8 As shown, the mounting assembly includes a dovetail groove 15, two guide grooves 13, multiple retaining strips 16, and several guide bars 14. The dovetail groove 15 is located at the bottom center of the blade body 11. The two guide grooves 13 are symmetrically located on both sides of the end of the blade body 11 near the dovetail groove 15. Each retaining strip 16 is fixed to the top of a blade 12. Each retaining strip 16 is inserted into the inside of the dovetail groove 15 and is slidably connected to the dovetail groove 15. The cross-section of the retaining strip 16 matches the cross-sectional shape of the dovetail groove 15. Each pair of guide bars 14 is fixed to the top of a blade 12 on both sides. Each guide bar 14 is inserted into the inside of a guide groove 13 and is slidably connected to the guide groove 13.

[0044] When it is necessary to install the blade 12 at the bottom of the blade body 11, the blade 12 is slid into the blade body 11 from one end, so that the retaining strip 16 can be inserted into the dovetail groove 15 and the two guide strips 14 can be inserted into the two guide grooves 13 respectively, thereby completing the initial connection between the blade body 11 and the blade 12.

[0045] In use, first fix a baffle 29 to one end of the blade body 11, then slide multiple blades 12 sequentially to the bottom of the blade body 11, and finally fix another baffle 29 to the other end of the blade body 11. This can fix and limit the blades 12, and stably install multiple blades 12 under the blade body 11.

[0046] like Figures 1-8 As shown, the limiting assembly includes two baffles 29 and multiple bolts 19. The two baffles 29 are respectively disposed at both ends of the blade body 11. The two blades 12 located at both ends abut against the baffles 29 at the ends. Multiple threaded holes 17 are provided at both ends of each blade body 11. Multiple through holes 18 are provided on the surface of each bolt 19. Each through hole 18 corresponds to one bolt 19. Each bolt 19 passes through one through hole 18 and is threadedly connected to one threaded hole 17. The connection between the blade body 11 and the baffles 29 can be realized through the bolts 19, which facilitates the subsequent installation and disassembly of the baffles 29.

[0047] like Figures 1-8 As shown, each clip 16 has a positioning hole 21 at one end and a positioning rod 20 that matches the positioning hole 21 at the other end. By setting the positioning rod 20 and the positioning hole 21 at both ends of the clip 16, two adjacent blades 12 can be connected end to end through the positioning rod 20 and the positioning hole 21, thereby improving the connection strength between multiple blades 12 and improving the stability of this cross-cutting blade.

[0048] like Figures 1-8 As shown, one of the baffles 29 has an insertion hole 23 on its surface, the size of which is the same as that of the positioning hole 21. Another baffle 29 has an insertion rod 22 fixed on its side near the blade body 11, the size of which is the same as that of the positioning rod 20.

[0049] When multiple blades 12 slide into the bottom of the blade body 11, the positioning rod 20 on one blade 12 at one end can be inserted into the insertion hole 23 on a baffle 29, while the insertion rod 22 fixed on one side of the other baffle 29 can be inserted into the positioning hole 21 on the blade 12 at the other end.

[0050] like Figures 1-8 As shown, the top of the blade body 11 is provided with a plurality of mounting grooves 26 that match the top cover 27 at equal intervals. Each filling cavity 25 is opened at the bottom end of the mounting groove 26 and each filling cavity 25 is connected to a mounting groove 26. The cross-sectional area of ​​the filling cavity 25 is smaller than the cross-sectional area of ​​the mounting groove 26. Each top cover 27 is snapped into the inside of a mounting groove 26 and each top cover 27 is fixedly connected to the blade body 11. The top cover 27 is used to seal the top of the filling cavity 25. It should be noted that the top cover 27 and the blade body 11 are connected by welding.

[0051] By filling each filling cavity 25 with phase change material, efficient heat transfer can be achieved, which can effectively avoid the situation where the temperature rises sharply during high-speed or high-intensity cutting, causing the tool to deform at high temperature, thus improving cutting accuracy.

[0052] like Figures 1-8 As shown, the surface of the blade body 11 is provided with multiple mounting holes 24, which are staggered with multiple mounting slots 26. The mounting holes 24 are designed to facilitate the installation of this cross-cutting blade.

[0053] The beneficial effects of this utility model are specifically reflected in the fact that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
