[0032] See also Figure 1-Figure 2 In an embodiment of the present invention, a meat slicing device includes a base 1, side panels 2 are fixedly connected to both sides of the base 1, a placing table 3 for placing meat is closely arranged in the middle of the upper end of the base 1, a fixing plate 4 is fixedly connected between the middle parts of the upper ends of the symmetrical side panels 2, a mounting plate 9 is fixedly connected to the middle part of the lower end of the fixing plate 4, a double-sided blade 10 for cutting meat is fixedly connected to the lower end of the mounting plate 9, a driving structure for driving the mounting plate 9 to move vertically is arranged in the middle part of the upper end of the mounting plate 9, and the driving structure includes a servo motor 5, which is transmission-connected to the upper end of the fixing plate 4. When the output end of the servo motor 5 rotates, it drives the mounting plate 9 to reciprocate in the vertical direction.

[0033] See also Figure 5-Figure 6The output end of the servo motor 5 is fixedly connected with a cam 21, and the side of the cam 21 away from the servo motor 5 is fixedly connected with a driving rod 22. A symmetrical balance rod is fixedly connected to the middle of the lower end of the fixed plate 4, and the outer wall of the balance rod is vertically slidably connected to the middle of both sides of the mounting plate 9, that is, when the mounting plate 9 moves in the vertical direction, the balance rod can limit the mounting plate 9 in the horizontal direction and guide it in the vertical direction, so that the mounting plate 9 can move more smoothly in the vertical direction. A driven rod 25 is vertically slidably connected to the middle of the upper end of the fixed plate 4, and a driven frame 23 is fixedly connected to the middle of the upper end of the driven rod 25. A driven groove 24 is opened in the middle of the driven frame 23, and the outer wall of the driving rod 22 is slidably connected to the inner cavity of the driven groove 24, that is, when the cam 21 moves along with the servo motor During the rotation of the machine 5, the driving rod 22 will be synchronously driven to rotate. Since the driving rod 22 slides with the driven groove 24, when the driving rod 22 rotates, the driven frame 23 will be driven to move in the vertical direction, thereby driving the driven rod 25 to move in the vertical direction. As the cam 21 continues to rotate, the driven frame 23 and the driven rod 25 will continuously reciprocate in the vertical direction. The end of the driven rod 25 away from the driven frame 23 passes through the fixed plate 4 and is fixedly connected to the mounting plate 9, so that the cam 21 is driven to rotate by the servo motor 5, and the driven frame 23, the driven rod 25 and the mounting plate 9 are driven to reciprocate continuously in the vertical direction, thereby driving the double-sided blade 10 to continuously reciprocate in the vertical direction, thereby conveniently cutting meat.

[0034] See also Fig. 9 A rotating column 39 is fixedly connected to the middle of the lower end of the placing table 3, and a push plate 41 is rotatably connected to the lower end of the rotating column 39. A cavity is opened in the inner cavity of the base 1, and the lower end of the push plate 41 is slidably connected to the bottom of the cavity. A first sliding groove that slides with the rotating column 39 is opened in the middle of the upper end of the base 1. A moving frame 40 is arranged above the push plate 41, and a driving groove 28 is opened in the middle of the moving frame 40. The outer wall of the rotating column 39 slides with the driving groove 28, and the outer wall of the moving frame 40 is slidably connected to the side wall of the cavity. An electric push rod is transmission-connected to one side close to the placement table 3, and the output end of the electric push rod is transmission-connected to the middle part of the moving frame 40 close to the placement table 3, that is, the electric push rod will push the moving frame 40 to reciprocate horizontally. During the movement of the moving frame 40, the rotating column 39 and the placement table 3 will be pushed to move synchronously, thereby driving the meat to synchronously approach the position of the double-sided blade 10, and the cutting process of the meat is completed through the relative movement of the placement table 3 and the double-sided blade 10 and the vertical reciprocating movement of the double-sided blade 10.

[0035] See also Figure 3A plurality of symmetrical grooves 6 are provided at the upper end of the placing table 3. The positions of the grooves 6 correspond to the positions of the double-sided blades 10. The horizontal width of the grooves 6 is greater than the horizontal width of the double-sided blades 10. After the placing table 3 is close to the double-sided blades 10, the double-sided blades 10 will be in the grooves 6 and will not touch the placing table 3 during the process of the double-sided blades 10 cutting the meat. When the placing table 3 drives the meat to contact the double-sided blades 10 for the first time, the double-sided blades 10 reciprocate in the vertical direction to cut the meat, so that the meat is divided into multiple meat strips during the first cutting process, until the moving frame 40 is pushed by the electric push rod to move to the other side of the cavity, that is, the moving frame 40 and the cavity are in contact. When the side of the interior away from the electric push rod is in contact, the initial cutting of the meat is completed, so that the meat is cut into multiple strips. In order to cut the meat strips into several small pieces, the meat strips need to be cut again. Since the horizontal length of the drive groove 28 is greater than the diameter of the rotating column 39, during the process of the electric push rod driving the moving frame 40 to reset, the side of the inner cavity of the drive groove 28 away from the electric push rod will be close to the outer wall of the rotating column 39, and the side of the inner cavity of the drive groove 28 close to the electric push rod will be away from the outer wall of the rotating column 39, until the side of the inner cavity of the drive groove 28 away from the electric push rod contacts the outer wall of the rotating column 39, the rotating column 39 will be driven to move horizontally again, thereby returning to the initial position.

[0036] See also Fig.10 A rack 42 is fixedly connected to the middle of one side of the inner cavity of the driving groove 28, and a gear 27 is fixedly connected to the middle of the outer wall of the rotating column 39. The rack 42 and the gear 27 are meshed with each other. When the moving frame 40 moves horizontally and the rotating column 39 remains stationary, the rack 42 and the gear 27 cooperate with each other to drive the rotating column 39 to rotate 90°, thereby driving the placement table 3 to rotate 90°. The rotation of the placement table 3 synchronously drives a number of meat strips to rotate 90°, that is, before the moving frame 40 pushes the rotating column 39 to move horizontally, it will first drive the rack 42 to move horizontally, so that the placement table 3 will rotate 90° before approaching the double-sided blade position. , so that the position of the meat strips is perpendicular to the position of the double-sided blade 10, so that when the moving frame 40 drives the placement table 3 to reset, the meat strips will contact the double-sided blade 10 again, and the double-sided blade 10 will perform a secondary cutting on the meat strips, and cut several meat strips into multiple meat pieces. By making the placement table 3 drive the meat strips to rotate 90° and drive the meat strips to approach the double-sided blade 10 again for secondary cutting, there is no need to manually place the meat strips for secondary cutting after the meat is cut into meat strips. At the same time, it also avoids the problem that the position of the meat strips is difficult to align when the meat strips are manually placed, resulting in excessive differences in the size of the small pieces of meat cut out.

[0037] See also Figure 3, a plurality of positioning rods 7 are fixedly connected around the placing table 3, and the positioning rods 7 are located between two adjacent grooves 6. Through the setting of the positioning rods 7, the space above the placing table 3 can be enclosed to a certain extent, thereby preventing the meat strips located at the corners of the placing table 3 from rotating due to the effect of inertia, causing part of the meat strips to exceed the side of the placing table 3, resulting in uneven meat pieces cut during the secondary cutting process of the meat strips. The reciprocating vertically moving double-sided blade 10 makes it easier to cut meat, while also continuously generating friction with the meat, especially after the meat is cut into meat strips, the friction between the double-sided blade 10 and the meat will cause the position of the meat to shift and affect the uniformity of cutting. For frozen meat, the influence of friction is relatively small, while for fresh meat, the friction generated by the double-sided blade 10 when cutting will have a greater influence on the position of the meat strips, which requires applying pressure to the meat during the cutting process to limit the position of the meat, thereby ensuring that the cut meat pieces are relatively uniform.

[0038] See also Figure 4, a plurality of pressing plates 11 are arranged above the placing table 3, and the length of the pressing plates 11 is greater than the length of the placing table 3, so that the placing table 3 can avoid the contact between the corners of the placing table 3 and the connecting rod 12 during the rotation of the rotating column 39, thereby affecting the rotation process of the placing table 3, and the lower end of the pressing plate 11 away from the placing table 3 is fixedly connected with the connecting rod 12, and the upper end surface of the base 1 is provided with a second sliding groove used to cooperate with the connecting rod 12, and the lower ends of the plurality of connecting rods 12 are fixedly connected with a No. 1 rod 17, and the plurality of pressing plates 11 are connected together by the fixed connection between the connecting rod 12 and the No. 1 rod 17, and a No. 2 rod 18 is arranged below the No. 1 rod 17, and the No. 2 rod 18 is slidably connected to the bottom of the cavity inner cavity, and a symmetrical telescopic rod 19 is fixedly connected to the middle part of the upper end of the No. 2 rod 18, and the upper end of the telescopic rod 19 is fixedly connected to the lower end of the No. 1 rod 17, and the telescopic rod 19 is a sliding telescopic rod commonly used in the prior art, so that the No. 1 rod 17 can move in the vertical direction relative to the No. 2 rod 18 When the moving frame 40 is moved, the second rod 18 will still drive the first rod 17 to move in the horizontal direction through the telescopic rod 19. The middle part of the end of the second rod 18 close to the rotating column 39 is fixedly connected to the end of the push plate 41 away from the rotating column 39. That is, when the rotating column 39 moves with the moving frame 40, the second rod 18 will be driven to move synchronously through the push plate 41, so that the placing table 3 and the pressing plate 11 can move synchronously. Then, in the process of the double-sided blade 10 cutting the meat, the pressing plate 11 will continue to apply pressure to the meat to avoid the position of the meat from being shifted. The pressing plate 11 close to the position of the first rod 17 is fixedly connected to the side of the side plate 2 with the extension plate 13, and the side edge of the extension plate 13 is fixedly connected to the position of the first rod 17 with the extension rod 15. The side wall of the extension plate 13 is fixedly connected to the side plate 2 with the first guide rod 14, and the top of the extension rod 15 is fixedly connected to the side plate 2 with the second guide rod 16. The first guide rod 14 and the second guide rod 16 only differ in their positions.

[0039] See also Figure 7A moving groove 29 is provided in the middle of one side of the side plate 2 close to the base 1, and a moving plate 30 is vertically slidably connected to the inner cavity of the moving groove 29. Two parallel guide grooves 33 are provided on the side of the moving plate 30 close to the base 1. The two guide grooves 33 are different only in their positions, that is, the outer wall of the second guide rod 16 on the side away from the extension rod 15 is slidably matched with the inner cavity of the guide groove 33 located above, and the first guide rod 14 is slidably matched with the guide groove 33 located below. When the pressing plate 11 moves synchronously with the placing table 3, the first guide rod 14 and the second guide rod 16 will slide in the inner cavity of the guide groove 33, and the guide groove 33 is away from the electric push rod A first inclined groove 34 is provided on one side of the guide groove 33, a second inclined groove 35 is provided on one end of the guide groove 33 away from the first inclined groove 34, and a balancing groove 36 is provided on one end of the second inclined groove 35 away from the guide groove 33. The vertical height of the two ends of the first inclined groove 34 is less than the vertical height between the two ends of the second inclined groove 35. When the rotating column 39 drives the placing table 3 to approach the position of the first inclined groove 34, the first guide rod 14 and the second guide rod 16 will enter the inner cavity of the guide groove 33 from the inner cavity of the balancing groove 36 through the second inclined groove 35. After the first guide rod 14 and the second guide rod 16 enter the inner cavity of the guide groove 33, the position of the pressing plate 11 remains fixed, thereby pressing the meat The second inclined groove 35 and the balancing groove 36 are arranged so that when the placing table 3 does not move, the pressing plate 11 can be away from the upper end surface of the placing table 3, so as to facilitate the placement of meat on the placing table 3, or the removal of the cut meat on the placing table 3 and the placement of new meat to be cut. The first inclined groove 34 guides the first guide rod 14 and the second guide rod 16, and the pressing plate 11 is separated from the meat strips when the placing table 3 stops moving and rotates, so as to facilitate the rotation of the placing table 3 and the meat strips. When the placing table 3 approaches the double-sided blade 10 again, the pressing plate 11 will limit and fix the position of the meat strips again. In the process of the extension plate 13 moving downward along with the pressure plate 11, in order to prevent the positioning rod 7 from hindering the downward movement of the extension plate 13 and the pressure plate 11, the positioning rod 7 is specially set to an elastic telescopic structure, that is, the positioning rod 7 is an elastic telescopic rod commonly used in the prior art, the lower part of which is fixed and the upper part can move in the vertical direction. In the process of the extension plate 13 moving downward, even if it contacts the upper part of the positioning rod 7, the upper part of the positioning rod 7 will automatically move downward without affecting the downward movement of the extension plate 13, and the upper part of the positioning rod 7 will fit with the lower part of the extension plate 13, and after the extension plate 13 is separated from the positioning rod 7, the upper part of the positioning rod 7 will automatically reset.

[0040] See also Figure 7-Figure 8In the process of cutting meat, the thickness of the meat will change, so the position of the pressing plate 11 also needs to change with the change of the thickness of the meat. A through slot 37 is provided on the upper side of the side wall of the base 1 near the electric push rod. A push rod 38 is slidably connected to the inner cavity of the through slot 37. The middle part of the push rod 38 is threadedly connected to a screw 20. The end of the screw 20 away from the through slot 37 is fixedly connected to the rotating wheel 8. The screw 20 can be driven to rotate synchronously by rotating the rotating wheel 8, so that the rotation of the screw 20 drives the The push rod 38 moves horizontally in the inner cavity of the through groove 37. Both ends of the push rod 38 are fixedly connected with sliding rods 31. The end of the sliding rod 31 away from the push rod 38 is slidably connected to the lower part of the inner cavity of the side plate 2. The lower end of the movable plate 30 is provided with an inclined surface 26. The sliding rod 31 is slidably connected to the middle part of the lower side of the movable plate 30. The outer wall of the sliding rod 31 is fixedly connected to the position near the inclined surface 26. The side of the inclined block 32 close to the inclined surface 26 is in contact with the side edge of the inclined surface 26. The horizontal width of the inclined block 32 is the same as that of the movable plate 30. The horizontal widths of the movable plates 30 are the same, and the horizontal widths of the inclined blocks 32 are greater than the horizontal widths of the sliding rods 31. When the screw rod 20 drives the push rod 38 to move horizontally, the push rod 38 will push the symmetrical sliding rod 31 to move horizontally, thereby driving the inclined blocks 32 to move horizontally through the sliding rod 31. The inclined blocks 32 cooperate with the inclined surfaces 26 to push the movable plate 30 to move in the vertical direction, thereby changing the distance between the guide groove 33 and the upper end surface of the placement table 3, thereby adapting to meat of different thicknesses. When the thickness of the meat changes, the height of the guide groove 33 can be changed by rotating the rotating wheel 8. The guide groove 33 will drive the pressure plate 11 to change its position by cooperating with the second guide rod 16 and the first guide rod 14, thereby driving the No. 1 rod 17 to move in the vertical direction through the connecting rod 12. Since the No. 1 rod 17 and the No. 2 rod 18 are connected by the telescopic rod 19, the telescopic rod 19 can be telescopic, and the position state of the No. 2 rod 18 will not affect the movement of the No. 1 rod 17 in the vertical direction.

[0041] A method for cutting meat into pieces comprises the following steps:

[0042] S1. Place the meat on the upper end surface of the placement table 3, and then start the electric push rod to push the moving frame 40 to move horizontally. After the inner cavity side wall of the driving groove 28 contacts the outer wall of the rotating column 39, it will push the rotating column 39 to drive the placement table 3 and the push plate 41 to move synchronously, and then drive the placement table 3 close to the double-sided blade 10 while allowing the pressing plate 11 to squeeze and limit the meat, so that the meat is cut into strips for the first time.

[0043] S2. While the moving frame 40 is being driven to reset by the electric push rod, the rotating column 39 is driven to rotate 90° through the cooperation of the rack 42 and the gear 27, and then approaches the position of the double-sided blade 10 again, thereby cutting the meat strips into meat chunks for the second time. After the cutting of the meat strips is completed, the pressing plate 11 is moved away from the position of the meat chunks again, thereby facilitating the removal of the cut meat chunks.
