[0006] Compared with the prior art, the present application has the following effects: the present invention effectively improves the strength of the knife by designing the maximum thickness of the blade to be 5.5-6mm, preventing problems such as edge curling, edge collapse, and deformation; by designing the blade angle to be 20-25° and the blade height to be 12-14mm, the blade angle is kept sharp (not too blunt) while having a certain strength, making the cut meat smooth and beautiful. Furthermore, the knife designed by the present invention not only effectively avoids edge curling, edge collapse, deformation, and even breakage of the knife, but also can achieve continuous deboning, and can be used in the automation and intelligent process of the segmentation production line.

[0007] Furthermore, the length of the blade is 140-160 mm.

[0008] Furthermore, the lower angle of the knife tip is 66-70°, and the upper angle of the knife tip is 10-14°.

[0009] Furthermore, it also includes a handle connected to the front end of the knife body, the front end of the knife body is provided with a raised outer arc structure, and the handle is provided with a recessed inner arc structure matching the outer arc structure, so that the knife body and the handle are automatically aligned and positioned when assembled.

[0010] Furthermore, the outer arc structure and the inner arc structure are both in number and are arranged one above the other.

[0011] Furthermore, the overall shape of the blade body is a stepped structure, and the blade tip is located at the lower end of the stepped structure.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 As shown, the utility model discloses a cutting tool, including a knife body 1, a knife tip 2 and a blade 3 are arranged at the rear end of the knife body 1, the maximum thickness of the knife body 1 is 5.5-6 mm, the angle 11 of the blade 3 is 20-25°, and the height of the blade 3 is 12-14 mm. The angle of the blade 3 can be referred to Figure 4 .

[0026] Compared with the prior art, the present application has the following effects: the present invention effectively improves the strength of the cutter through the design of the maximum thickness of the blade being 5.5 to 6 mm, preventing problems such as edge curling, edge collapse, and deformation; through the design of the blade angle 11 being 20-25° and the blade height being 12-14 mm, the blade angle of the blade 3 is kept sharp (not too blunt) while having a certain strength, making the cut meat smooth and beautiful. Furthermore, the cutter designed by the present invention not only effectively prevents the cutter from edge curling, edge collapse, deformation, and even breakage, but also can achieve continuous deboning, and can be used in the automation and intelligent process of the segmentation production line.

[0027] Continuing with the above embodiment, it is more preferred that the length of the blade 3 is 140-160 mm. If the length of the blade 3 is too short, the robot arm is likely to touch the cut product when operating the knife body. If the length of the blade 3 is too long, it may be deformed due to the force.

[0028] In the above embodiment, it is more preferred that the lower angle 4 of the blade tip 2 is 66-70°, and the upper angle 5 of the blade tip 2 is 10-14°. If the blade tip 3 is too sharp, it does not meet the safety production regulations, and if it is not too sharp, the sharpness cannot be guaranteed, so the present application selects the above angle of the blade tip 2.

[0029] Continuing with the above embodiment, it is more preferred that it also includes a handle 6 connected to the front end of the blade body 1, the front end of the blade body 1 is provided with a raised outer arc structure 7, and the handle 6 is provided with a recessed inner arc structure 8 matching the outer arc structure 7, so as to automatically align and position the blade body 1 and the handle 6 when they are assembled.

[0030] Continuing with the above embodiment, more specifically, both the outer arc structure 7 and the inner arc structure 8 are two and are arranged up and down. Through the upper and lower cooperation, the outer arc structure 7 and the inner arc structure 8 are more firmly assembled.

[0031] Continuing with the above embodiment, it is more preferred that the overall shape of the blade body 1 is a stepped structure, and the blade tip 2 is located at the lower end of the stepped structure, so that the blade body 1 is more evenly stressed, thereby improving the firmness of the blade body 1.

[0032] Continuing with the above embodiment, more preferably, the handle 6 and the blade body 1 are connected by bolts 9 .

[0033] Continuing with the above embodiment, it is more preferred that the gap between the knife handle 6 and the knife body 1 after being assembled is smaller than the gap between the bolt 9 and the bolt hole after being assembled, so as to ensure that when the knife body 1 is subjected to force, the outer arc structure 7 and the inner arc structure 8 are subjected to force first, thereby reducing the force on the bolt 9, thereby increasing the service life of the bolt, and also ensuring that the knife body 1 will not move relative to the knife handle 6 after multiple uses. In other words, the position of the knife tip 2 will not change, thereby ensuring the accuracy of the knife position each time.

[0034] It should be noted that the outer arc structure 7 and the inner arc structure 8 are assembled to form a positioning mechanism. During use, when the tip 2 penetrates into the meat, the blade 1 is subjected to force in the front-to-back direction, and the positioning mechanism will be subjected to force first, reducing the shear force of the blade 1 on the connecting bolt 9 to extend the service life of the bolt 9, reducing the force on the bolt 9, and preventing the bolt 9 from loosening. If there is no such positioning mechanism, the fatigue resistance of the bolt 9 is poor, and it is necessary to frequently check whether the bolt 9 is loose. If the bolt 9 is loose, there may be a risk of the knife flying out; when the blade 3 cuts meat or periosteum, the blade 1 is subjected to force in the up and down directions, and the back of the blade and the positioning mechanism are also subjected to force first, and the effect is the same as above; after the blade 1 and the handle 6 are assembled, the gap is extremely small and is smaller than the assembly gap of the mounting bolt hole. In this way, during the working process, the force points of the blade 1 on the handle 6 are all as described above, reducing the force on the connecting bolt 9, and at the same time ensuring that the blade 1 will not move relative to the handle 6 after multiple uses. In this way, the tip 2 is also fixed relative to the robot arm coordinate system, which can ensure the accuracy of the position of each knife.

[0035] Continuing with the above embodiment, it is more preferred that a tool retreat groove 11 is further provided on the tool handle 6, and the tool retreat groove 11 facilitates tool retreat during the machining process.

[0036] To sum up, the external shape of the knife body 1 and the parameter settings of various parts of the new design ensure that the strength and toughness of the tool are guaranteed during use, while taking into account a certain degree of sharpness, so that the two reach a good balance and can better meet the use requirements; at the same time, the gap between the knife body 1 and the knife handle 6 after assembly is extremely small and smaller than the assembly gap of the mounting bolt hole, so that during operation, the force points of the knife body 1 on the knife handle 6 are all positioning mechanisms, reducing the force on the connecting bolts 9.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
