Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0036] It is also important to note that the terms used herein are not intended to limit the exemplary embodiments to the specific embodiments described herein, but rather, are intended to provide further description of the exemplary embodiments according to the present application. As used herein, unless otherwise indicated, the use of the singular includes the plural and back again; and, also, it is understood that the terms "includes," "including," "comprises," and / or "comprising," as used herein, specify the presence of features, steps, operations, devices, components, and / or combinations thereof;

[0037] Embodiment One:

[0038] The existing fascia removal method generally uses a fascia knife in a sheet shape to remove part of the fascia after the meat product is thawed. Not only is the procedure cumbersome, but the sanitary conditions of the thawed meat product cannot be guaranteed. For frozen meat products, due to their hardness and irregular shape, the existing fascia knife cannot remove the fascia in the frozen state.

[0039] To solve the above problems, the embodiment one of the present application provides a fascia removal knife suitable for processing frozen beef, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , which comprises a connecting plate 1, a driving motor 2, a power transmission shaft 3, a cutting milling cutter 4, a milling cutter depth adjusting plate 5, a milling cutter fixing seat 6, a flexible floating hinge 7, a steel wire rope 8 and a supporting bearing 9.

[0040] The cutting milling cutter 4 comprises a cutter body and a rotating shaft, one end of the rotating shaft is connected with the cutter body, bearings are installed on both sides of the rotating shaft and connected with the cutter body, and the cutter body is rotated by driving the bearings. The cutter body comprises a plurality of blades 20, and the cutting edge part of the blade 20 separates the fascia from the meat by high-speed rotation. The power transmission shaft 3 is a flexible shaft, one end of the power transmission shaft 3 is connected with the rotating shaft of the cutting milling cutter 4, and the other end is connected with the driving motor 2. The milling cutter fixing seat 6 is used to fix the cutter body and the rotating shaft relatively, and the milling cutter fixing seat 6 is connected with the rotating shaft of the cutting milling cutter 4 through the supporting bearing 9. The milling cutter depth adjusting plate 5 is used to limit the depth of the cutting milling cutter embedded in the meat product, and the milling cutter depth adjusting plate 5 has two pieces, which are installed on the front side and the rear side of the cutting milling cutter 4 respectively. The connecting plate 1 has a flexible floating hinge 7 connected at both ends, one end of the connecting plate 1 is connected with the milling cutter fixing seat 6 through the first flexible floating hinge 7, and the other end is connected with the driving motor 2 through the second flexible floating hinge 7; one end of the steel wire rope 8 is connected with the connecting plate 1, and the other end is connected with the milling cutter fixing seat 6, which is used to adjust the initial position of the cutting milling cutter to avoid the cutting milling cutter from falling due to gravity.

[0041] In this embodiment, the cutting milling cutter is made of alloy steel material, and can separate beef fascia from beef by high rotation. Since the beef fascia is difficult to remove, the fascia removing cutter of the present application is not limited to removing beef products, but can also remove fascia of mutton, pork and other meat products. However, the present embodiment is suitable for frozen meat products, and is not suitable for fresh meat or thawed meat products.

[0042] As shown in Figure 5 The main body of the cutting milling cutter is cylindrical, and the side surface of the main body is provided with a plurality of outwardly extending blades 20. The rotating shaft penetrates the cutting milling cutter body and forms a long shaft 18 and a short shaft 19 at both ends. The long shaft 18 side is provided with a key groove 17, and the long shaft 18 side is connected to the coupling through the key groove 17, so that the long shaft 18 side is connected to the power transmission shaft 3 through the coupling. The long shaft 18 side and the short shaft 19 side are respectively installed on the first fixed plate 12 and the third fixed plate 13 of the milling cutter fixing seat through the supporting bearing 9.

[0043] In this embodiment, the elastic floating hinge includes a first elastic floating hinge and a second elastic floating hinge, and the connecting plate is L-shaped. The longer end is connected to the driving motor through the second elastic floating hinge, and the shorter end is connected to the milling cutter fixing seat through the first elastic floating hinge. In this way, sufficient floating space can be provided for the power transmission shaft.

[0044] The elastic floating hinge is connected to the connecting plate by screws. As shown in Figure 3 The second elastic floating hinge is not directly connected to the motor. One side of the second elastic floating hinge is installed on the L-shaped connecting plate through two screw holes, and the other side is installed on the milling cutter fixing seat through two screw holes. Specifically, it refers to the extension plate extending obliquely upward on the third fixed plate of the milling cutter fixing seat 6, as shown in Figure 4

[0045] The elastic floating hinge 7 is composed of two plate-shaped hinges made of aluminum alloy material. A round shaft 15 is arranged in the middle of the two hinges, and the two hinges are combined together through the round shaft 15. A spring 16 is added to the round shaft 15, so that the two plate-shaped hinges can rotate around the shaft while having a certain elastic force. The elastic force of the elastic floating hinge provides the downward force of the cutter, and the cutting milling cutter is pressed on the meat surface. When the pressure exceeds the elastic force of the spring on the hinge, it will adaptively float up. The cutting milling cutter is always attached to the meat surface with uniform force. In this embodiment, the elastic force of the elastic floating hinge can be self-defined by adjusting the spring of the elastic floating hinge. The purpose of the steel wire rope is to prevent the cutting milling cutter from tilting downward due to the downward elastic force of the spring at the beginning, which causes inaccurate attachment to the meat surface. Therefore, the direction of the cutting milling cutter is constrained at a suitable horizontal position by the steel wire rope. As shown in Figure 3 ​As shown, the tension of the steel wire is to ensure that the initial state of the cutter is horizontal, and will not be pressed down by the elastic force of the hinge, so that the cutter is initially smoothly attached to the meat surface. Figure 4 As shown, the steel wire 8 is fixed to the lower cutter fixing seat 6 through the hook 10, and is fixed to the upper connecting plate through the clasp. The position of the steel wire clamped by the clasp is adjustable, so as to realize the adjustment and fixation of the length.

[0046] In this embodiment, the driving motor provides rotary power for the cutting mill. By adjusting the rotating speed of the driving motor, the cutting mill is driven to realize different rotating speeds for cutting the fascia.

[0047] In this embodiment, the cutter fixing seat is composed of a first fixing plate 12, a second fixing plate 14 and a third fixing plate 13 connected in sequence. The first fixing plate 12 and the third fixing plate 13 are the same shape and parallel, and the second fixing plate 14 is perpendicular to the first fixing plate 12 and the third fixing plate 13, as shown in FIG. 4. The rotating shaft of the cutting mill is provided with a support bearing at both ends, and the two support bearings are connected with the first fixing plate and the third fixing plate of the cutter fixing seat, which can reduce the friction resistance of the cutting mill rotating and improve the transmission efficiency. The second fixing plate 14 is also designed with an extension plate 11 extending obliquely upward, and the first elastic floating hinge is fixed on the extension plate 11 through two threaded holes.

[0048] The cutter fixing seat is used for fixing the cutter head, and the first fixing plate and the third fixing plate of the cutter fixing seat are provided with through holes corresponding to the rotating shaft, and the support bearings are installed in the through holes to support the rotating shaft and maintain the rotating action. The rotating shaft is a stepped shaft, and the two ends can be inserted into the holes of the support bearings to realize fixation.

[0049] In this embodiment, the two pieces of cutter depth adjusting plates are the same and parallel, which can limit the depth of the cutting mill embedded in the beef, realize the control of the cutting amount, and reduce the loss of meat quality in the process of removing the fascia. The side surface of the cutter depth adjusting plate is crescent-shaped, and the cutter depth adjusting plate is distributed on both sides of the cutter body to wrap the cutter body and support on the meat surface. The cutter depth adjusting plate adjusts the exposed length of the cutter head by the length of the crescent in the upward and downward directions. If the crescent of the adjusting plate is short, the cutter is exposed more, and the cutting depth is deeper. Conversely, the same principle applies. The cutter depth adjusting plate is fixed below the first fixing plate and the third fixing plate of the upper cutter fixing seat through screw connection. The cutter depth adjusting plate has multiple different sizes, and the cutter head feeding depth is adjusted by replacing the cutter depth adjusting plate.

[0050] In the embodiment, the surface of the connecting plate is provided with a plurality of mounting holes, and the fascia knife is connected with the fixing device through the mounting holes. The fixing device can be an operating table, a mechanical arm, a robot or any carrier that can support the fascia knife of the application. The fascia knife of the application can effectively compensate for the visual error of the artificial or visual recognition device caused by the uneven surface of the meat during cutting, and can make the cutting mill more closely fit the different concave and convex surfaces of the frozen meat surface, so as to realize the complete removal of the fascia.

[0051] Embodiment two

[0052] The embodiment two of the application provides a use method of the fascia knife in the embodiment one, and the use method comprises the following steps:

[0053] The meat product to be processed is in a frozen state, and the surface of the meat product to be processed is provided with a known fascia area. The initial position of the cutting mill is adjusted by the steel wire rope, so that the cutting edge of the cutter body contacts the fascia area. The depth adjusting plate of the mill is adjusted according to the thickness of the fascia, the driving motor is used to drive the rotation of the rotating shaft of the cutting mill, the cutter body is rotated, and the cutting edge of the cutter body removes the fascia of the meat product.

[0054] The steps in the above embodiment two correspond to the embodiment one, and the specific implementation can refer to the related description part of the embodiment one.

[0055] Although the specific embodiments of the application are described above with reference to the accompanying drawings, the description is not a limitation on the protection scope of the application. It should be understood by those skilled in the art that various modifications or changes made on the basis of the technical solutions of the application without creative labor are still within the protection scope of the application.
