Description

[Technical Field]

[0001] This invention relates to the field of bone-cutting machine technology, and more specifically to a cutting machine with a composite blade mechanism. [Background Technology]

[0002] Shops, restaurants, and food processing plants selling fresh and frozen meat use various methods when cutting bones such as ribs, spine, and thigh bones. Some use large cleavers to chop them manually, others use electric saws, and still others use automated bone-cutting equipment. Some meats, especially beef, have a lot of tendons, and the shearing blades of existing bone-cutting machines in the market often struggle to completely sever these tendons, requiring additional manual processing and increasing the operation time. [Summary of the Invention]

[0003] To address the aforementioned technical problems, this invention proposes a cutting machine with a composite blade mechanism. This small tabletop bone cutter occupies little space, consumes little power, and is suitable for cutting small batches of meat, bones, and other foods. The composite blade mechanism is suitable for cutting small batches of meat, bones, and other foods, and can cut tendons in the meat. It has low cutting resistance, long service life, and the cutting blade is easy to disassemble, sharpen, or replace.

[0004] The specific technical solution provided by this invention is as follows:

[0005] A cutting machine with a composite blade mechanism is characterized by comprising a worktable, a fixed mating blade disposed on the worktable, a movable blade disposed above the fixed mating blade, a movable mating blade disposed below the fixed mating blade, and a drive mechanism capable of driving the movable blade to move, wherein the drive mechanism is connected to the movable blade, so that the movable blade, the fixed mating blade, and the movable mating blade cooperate with each other to achieve cutting.

[0006] A cutting machine with a composite blade mechanism as described above is characterized in that the worktable is provided with a blade holder for mounting the movable mating blade, and a connecting device is provided between the movable mating blade and the blade holder.

[0007] A cutting machine with a composite blade mechanism as described above is characterized in that the movable cooperating blade is elastic.

[0008] A cutting machine with a composite blade mechanism as described above is characterized in that an elastic element is provided between the movable mating blade and the blade holder, and the movable mating blade is provided with an adjustment device for adjusting the connecting device.

[0009] The cutting machine with a composite blade mechanism as described above is characterized in that the moving blade consists of a moving blade holder and a cutting blade, and the moving blade holder and the cutting blade are detachably connected.

[0010] The cutting machine with a composite blade mechanism as described above is characterized in that the driving mechanism is an electric push rod or an electric cylinder, and the output end of the driving mechanism is connected to the moving blade.

[0011] A cutting machine with a compound blade mechanism as described above is characterized in that the drive mechanism includes a handle.

[0012] The cutting machine with a composite blade mechanism as described above is characterized in that the driving mechanism is a hydraulic cylinder, and the output end of the hydraulic cylinder is connected to the moving blade.

[0013] A cutting machine with a composite blade mechanism as described above is characterized in that the moving blade has a first blade on the side facing the fixed blade, the fixed blade has a second blade on the side facing the moving blade, and the movable blade has a third blade on the side facing the moving blade, wherein the first blade and the second blade form an included angle b, and the included angle b is within the range of 0° to 50°.

[0014] A cutting machine with a composite blade mechanism as described above is characterized in that the end of the first blade 31 that first completes the cutting action is a pilot end; a first inclined slit that avoids the pilot end is provided on the side of the fixed blade opposite to the pilot end; a second blade is formed between the other side of the fixed blade and the first inclined slit, and the second blade is in close contact with the first blade; a second inclined slit that avoids the pilot end is provided on the side of the movable blade opposite to the pilot end; and a third blade is formed between the other side of the movable blade and the second inclined slit, and the third blade is in close contact with the first blade.

[0015] The beneficial effects of this invention are as follows:

[0016] (1) The movable blade is set up and used in conjunction with the moving blade and the fixed blade to cut the tendons in the meat more effectively and reduce the time spent on manual processing of tendons later. A connecting device is set between the movable blade and the blade holder, and an adjustment device is set on the connecting device to prevent the movable blade from moving during the cutting process. An elastic element is set on the connecting device to contact the movable blade and the blade holder respectively. When the adjustment device is in the unlocked state, the elastic element pushes the movable blade and the connecting device to move, which makes it convenient for the user to adjust the relative position between the movable blade, the fixed blade, and the moving blade.

[0017] (2) The moving blade, fixed blade and movable blade adopt convenient fixing device. When the blade wears out quickly and needs to be sharpened, the operator can easily remove the blade for sharpening or replace it with a spare blade to quickly restore the machine to work without the need for professional personnel to disassemble and adjust.

[0018] (3) During the shearing process, the first and second cutting edges form a certain angle, and the first and third cutting edges also form a certain angle. The various positions on the first cutting edge cooperate with the second and third cutting edges at different times to complete the shearing action, resulting in low cutting resistance and long service life.

[0019] (4) When the moving blade moves toward the fixed and movable blades, the pilot part on the moving blade first enters the area where the first inclined cut is located. At this time, there is a gap between the pilot part and the surface of the first inclined cut. As the moving blade continues to fall, the first cutting edge gradually comes into contact with the second and third cutting edges, completing the shearing action. In this process, the first and second inclined cuts can guide the moving blade and avoid rigid collisions. [Image Description]

[0027] The following will combine Figures 1 to 6 A cutting machine with a composite blade mechanism according to an embodiment of the present invention will be described in detail.

[0028] like Figures 1 to 6As shown, an embodiment of the present invention proposes a cutting machine with a composite blade mechanism, including a worktable 1, a fixed mating blade 2 disposed on the worktable 1, a movable blade 3 disposed above the fixed mating blade 2, a movable mating blade 9 disposed below the fixed mating blade 2, and a drive mechanism 8 capable of driving the movable blade 3 to move. The drive mechanism 8 is connected to the movable blade 3, so that the movable blade 3 cooperates with the fixed mating blade 2 and the movable mating blade 9 to achieve cutting.

[0029] like Figures 1 to 5 In the first embodiment shown, the workbench 1 is provided with a tool holder 10 for mounting the movable mating tool 9, and a connecting device 101 is provided between the movable mating tool 9 and the tool holder 10.

[0030] An elastic element 1011 is provided between the movable mating blade 9 and the blade holder 10, and the movable mating blade 9 is provided with an adjustment device 1012 for adjusting the connecting device 101.

[0031] In one embodiment of the present invention, the elastic element 1011 is a spring with strong elasticity; the moving blade 3 is composed of a moving blade holder 33 and a cutting blade 32, and the moving blade holder 33 and the cutting blade 32 are detachably connected.

[0032] In actual use, the user rotates the adjustment device 1012 to adjust the position of the connecting device 101 on the tool holder 10. The elastic element 1011 on the connecting device 101 contacts the movable mating knife 9 and the tool holder 10 respectively. The elastic element 1011 pushes the movable mating knife 9 and the connecting device 101 to move, so that the user can adjust the relative position between the movable mating knife 9 and the fixed mating knife 2 and the moving knife 3. When the adjustment device 1012 is tightened, during the falling of the moving knife 3, the movable mating knife 9 is squeezed by the moving knife 3 and pushed back by the strong elasticity of the elastic element 1011, thus adaptively and tightly adhering to the moving knife 3.

[0033] like Figure 6 In the second embodiment shown, the movable mating blade 9 is elastic. During the falling process of the moving blade 3, the movable mating blade 9 is squeezed by the moving blade 3, and at the same time, due to the elasticity of the movable mating blade 9, it adaptively adheres to the moving blade 3.

[0034] In order to enable the moving blade 3 to cooperate with the fixed blade 2 and the movable blade 9 to achieve cutting, in the first embodiment of the present invention, the driving mechanism 8 is an electric push rod or an electric cylinder, and the output end of the driving mechanism 8 is connected to the moving blade 3.

[0035] In the second embodiment of the present invention, the drive mechanism 8 is a motor, and the output end of the drive mechanism 8 is connected to the moving blade 3 through a transmission mechanism. The transmission mechanism is a crank rocker mechanism, a connecting rod mechanism, a lead screw and nut mechanism, a ball screw and nut mechanism, or a gear and rack mechanism.

[0036] Using the above-mentioned electric drive mechanisms 8 as power sources, compared with hydraulic and pneumatic power sources, they have the advantages of small size and low noise, and are suitable for small-batch cutting and processing of fresh meat, frozen meat, bones and other ingredients.

[0037] In the third embodiment of the present invention, the drive mechanism 8 includes a handle, which is connected to the moving blade 3 through a transmission mechanism. The transmission mechanism can be a linkage mechanism or a gear and rack mechanism.

[0038] In the fourth embodiment of the present invention, the driving mechanism 8 is a hydraulic cylinder, and the output end of the hydraulic cylinder is connected to the moving blade 3.

[0039] Optionally, a crossbeam 7 is fixed to the workbench 1, and a drive mechanism 8 is mounted on the crossbeam 7.

[0040] Furthermore, the moving blade 3 is provided with a first cutting edge 31 on the side facing the fixed fitting blade 2, the fixed fitting blade 2 is provided with a second cutting edge 21 on the side facing the moving blade 3, and the movable fitting blade 9 is provided with a third cutting edge 91 on the side facing the moving blade 3. An included angle b is formed between the first cutting edge 31 and the second cutting edge 21, and the included angle b is within the range of 0° to 50°; the included angle b is preferably 0.8° to 5°.

[0041] A guiding mechanism is provided on workbench 1.

[0042] Preferably, the guiding mechanism includes a vertical guide post 4 disposed on the worktable 1, and a sliding device 5 disposed on the moving blade 3 that cooperates with the vertical guide post 4.

[0043] In some embodiments of the present invention, a guide rail type guiding mechanism can be used to replace the above-mentioned vertical guide post 4 and sliding device 5; or a hinge device can be used as the guiding mechanism, and the hinge device can be operated manually to realize the up and down movement of the moving blade 3.

[0044] The worktable 1, fixed mating knife 2, movable mating knife 9, vertical guide column 4, and crossbeam 7 can be an assembled structure for easy disassembly and assembly; or they can be a welded integrated structure, wherein the sliding device 5 can be moved up and down and mounted on the vertical guide column 4, and the movable knife 3 is fixedly installed on the sliding device 5.

[0045] The movable blade 3 is preferably rectangular, with the first cutting edge 31 positioned on its hypotenuse. The fixed fitting blade 2 and the movable fitting blade 9 are also preferably rectangular. However, the fixed fitting blade 2, the movable fitting blade 9, and the movable blade 3 can also adopt other shapes. For example, the movable blade 3 can be rectangular, and the fixed fitting blade 2 and the movable fitting blade 9 can be right-angled trapezoids. Alternatively, the fixed fitting blade 2, the movable fitting blade 9, and the movable blade 3 can all be right-angled trapezoids. Or, the fixed fitting blade 2 and the movable blade 3 can be set to other shapes, as long as the included angle b is within the range of 0° to 50°.

[0046] Because the first cutting edge 31 and the second cutting edge 21 form a certain angle during the shearing process, and the first cutting edge also forms a certain angle with the third cutting edge 91, the various positions on the first cutting edge 31 cooperate with the second cutting edge 21 and the third cutting edge 91 at different times to complete the shearing action, resulting in low cutting resistance and long service life.

[0047] Reference Figure 2 As a further improvement of the present invention, the end of the first blade 31 that first completes the shearing action is the pilot end 311. A first inclined cut 22 that avoids the pilot end 311 is provided on the side of the fixed-fitting blade 2 opposite to the pilot end 311. The second blade 21 is formed between the other side of the fixed-fitting blade 2 and the first inclined cut 22. The second blade 21 is in close contact with the first blade 31. A second inclined cut 92 that avoids the pilot end 311 is provided on the side of the movable-fitting blade 9 opposite to the pilot end 311. The third blade 91 is formed between the other side of the fixed-fitting blade 2 and the first inclined cut 92. The third blade 91 is in close contact with the first blade 31. Preferably, there is a certain amount of interference when the second blade 21 and the first blade 31 cooperate with each other, and there is also a certain amount of interference when the third blade 91 and the first blade 31 cooperate with each other.

[0048] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In the embodiment of the moving blade 3, the second blade 21 is disposed on the upper side of the fixed-fitting blade 2, the inclined cut 22 extends inclined downward from the upper side of the fixed-fitting blade 2 to the left side of the fixed-fitting blade 2, and the second inclined cut 92 extends inclined downward from the upper side of the movable-fitting blade 9 to the left side of the movable-fitting blade 9.

[0049] When the moving blade 3 moves toward the fixed-fitting blade 2, the pilot part on the moving blade 3 first enters the area where the first inclined cut 22 is located. At this time, there is a gap between the pilot part and the surface of the first inclined cut 22. The moving blade 3 continues to fall, and the first cutting edge 31 gradually comes into contact with the second cutting edge 21, completing the cutting action. Then the moving blade 3 moves toward the movable-fitting blade 9, and the pilot part on the moving blade 3 enters the area where the second inclined cut 92 is located. At this time, there is a gap between the pilot part and the surface of the second inclined cut 92. The moving blade 3 continues to fall. Because the elastic element 1011 has strong elasticity, when the moving blade 3 falls, the third cutting edge 91 adaptively comes into close contact with the first cutting edge 31 under the action of the elastic element 1011, completing the cutting action. Especially for meat with a lot of tendons, after the first cutting edge 31 and the second cutting edge 21 come into contact and cut the hard bone, the soft tendons that are not completely cut will fall onto the third cutting edge 91. The first cutting edge 31 and the third cutting edge 91 come into close contact and cut the remaining tendons. In these processes, the areas where the first inclined incision 22 and the second inclined incision 92 are located can guide the knife 3 and avoid rigid collisions. Thus, the problem of hard-soft conflict between hard bones and soft tendons is solved.
