Description

Technical Field

[0001] The invention relates to the technical field of frozen raw beef tallow cutting, and in particular to a frozen raw beef tallow cutting system. Background Art

[0002] In tallow production, tallow cutting is an important part of the preliminary processing to optimize subsequent processing steps and improve production efficiency. The main purpose of tallow cutting is to cut large pieces of frozen raw tallow into small pieces suitable for subsequent processing, so as to facilitate uniform heating, melting and further processing. This process includes freezing treatment, selection of cutting equipment and application of cutting technology. Tallow re-cutting is crucial to production efficiency and product quality. The existing technology usually uses mechanical cutting to process frozen raw tallow. The advantages of mechanical cutting are low equipment cost and relatively simple operation. The existing mechanical cutting methods usually use equipment such as band saws, circular saws or slicers, which can efficiently cut the tallow into uniform blocks. However, the existing frozen raw tallow cutting equipment still has the following problems:

[0003] (1) Existing cutting equipment can usually only cut and produce frozen raw beef tallow blocks of preset particle sizes, and different beef tallow melting equipment has different requirements for the optimal size of beef tallow particles. This mainly depends on the heating method, processing capacity, melting efficiency and design characteristics of the equipment. Indirect heating equipment, such as electric furnaces or steam heating devices, are generally more suitable for smaller particles because they can melt more evenly and quickly. Direct heating equipment may have looser requirements on particle size, but uniform particles help to achieve stable melting results. In addition, large-scale processing equipment often accepts larger particles, while precision equipment may require smaller and more uniform particles to ensure the uniformity and efficiency of the melting process. Therefore, the size of frozen raw beef tallow blocks required by specific melting equipment types and production needs will be different;

[0004] (2) When cutting frozen raw beef fat with existing cutting equipment, the fascia at the bottom is difficult to cut effectively after cutting the frozen raw beef fat to the bottom, so that the beef fat cannot be effectively separated. This is because the toughness of the fascia may make it difficult for the cutting blade to cut completely, thereby affecting the cutting efficiency and the quality of the frozen raw beef fat particles. Summary of the invention

[0005] The object of the present invention is to provide a frozen raw beef tallow cutting system to solve the above problems.

[0006] The present invention is achieved through the following technical solutions:

[0007] A frozen raw beef tallow cutting system comprises a conveying unit, an unpacking unit and a cutting unit, wherein the conveying unit is used to convey materials to the unpacking unit, the unpacking unit is used to unpack the materials and push the unpacked materials to the cutting unit, and the cutting unit is used to cut the materials and output the cut materials through the conveying unit.

[0008] The unpacking unit includes a cutting assembly, a push plate, an unpacking platform and an air suction assembly, wherein the push plate includes a base plate, a bag placing box, a first telescopic rod, a bag rolling roller and a driving mechanism thereof; the unpacking platform includes an adsorption portion, a bag suction port and a negative pressure suction port; the air suction assembly is connected to a suction pump and a vacuum negative pressure machine corresponding to the bag suction port and the negative pressure suction port respectively;

[0009] The cutting unit is provided with a cutting box, which includes a first cutting knife, a roller cutter and a second cutting knife, wherein first screw rods are provided at both ends of the first cutting knife, the first screw rod is meshed with a first nut, the first nut is fixed with a vertical groove piece, the first cutting knife is slidably arranged on the vertical groove piece, the vertical groove piece is also provided with a third telescopic rod, the third telescopic rod is connected to the first cutting knife, and the third telescopic rod is used to drive the first cutting knife to slide up and down; the roller cutter includes a main roller, a plurality of annular blades and a distance adjustment mechanism, the plurality of annular blades are coaxially arranged on the main roller, the edges of the plurality of annular blades are all slidably connected to the distance adjustment mechanism, the distance adjustment mechanism includes a plurality of limit clamps, a scissors telescopic frame and a second screw rod, each annular blade corresponds to a limit clamp, the limit clamp is hinged on the scissors telescopic frame, the second screw rod is used to adjust the telescopic of the scissors telescopic frame, and the main roller is connected to the first motor; the second cutting knife is correspondingly provided with a first transmission wheel, the first transmission wheel is provided with an eccentric shaft, the second cutting knife is connected to the eccentric shaft through a connecting rod, and the first transmission wheel is connected to the second motor.

[0010] In general, the conveying unit included in the present invention includes a first conveyor belt and a second conveyor belt, wherein the first conveyor belt is connected to the unpacking unit, and the unpacking unit has a material pushing function (rolling away the material bag during the pushing process) in addition to the unpacking function, and the cutting unit includes a cutting box, and the first screw rod and the second screw rod of the cutting box are respectively used to adjust the thickness of the slices of the first cutting knife and the width of the strips cut by each annular blade, and the cutting box can adjust the length and width of the longitudinal surface of the material strips by adjusting the first screw rod and the second screw rod, and finally the cutting box cuts the material strips into particles by adjusting the cutting speed of the second cutting knife (the material strips are transported to the second conveyor belt by the cutting box, in coordination with the conveying speed of the second conveyor belt), and the cutting box can customize the size of the cut material particles by rotating the first screw rod, the second screw rod and adjusting the cutting speed of the second cutting knife.

[0011] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0012] 1. The cutting equipment in the prior art usually cuts frozen raw beef tallow into particles of fixed size, mainly because these devices are designed with standardized cutting modes to simplify operation and maintenance. This fixed particle size facilitates the adjustment and management of the equipment, but lacks flexibility in meeting the needs of different smelting equipment, limiting the ability to handle different size requirements. The present invention controls the distance between the first cutting knife and the abutment plate through a first screw rod, thereby controlling the thickness of the slices cut by the first cutting knife, and controls the width of the cut wire strips by adjusting the spacing between the multiple annular blades on the main roller through a second screw rod in conjunction with a scissors telescopic frame and multiple limit clamps. Finally, the size of the cut particles is controlled by controlling the cutting speed of the second cutting knife, so that the present invention can customize the finished size of the frozen raw beef tallow cut particles, thereby improving the adaptability of the present invention in different application scenarios;

[0013] 2. When cutting frozen raw beef fat, the cutting equipment in the prior art often fails to effectively cut the fascia at the bottom of the frozen raw beef fat when cutting to the bottom, which makes it difficult to completely separate the beef fat. This is because the toughness of the fascia makes it difficult for the cutting blade to completely cut, thereby affecting the cutting efficiency and the quality of the frozen raw beef fat particles. The present invention forms a scissors-like design between the first cutting knife and the bottom plate, so that the first cutting knife can effectively separate the fascia. In addition, the present invention arranges the sliding connection side of each annular blade and the limiting clamp on the side where the frozen raw beef fat slices are cut. After the frozen raw beef fat slices are squeezed and cut by each annular blade and the curved plate, the fascia adhesion that may exist in the gap between the two is blocked by the limiting clamp and forcibly separated, thereby completing the separation of the fascia of the frozen raw beef fat strips. Finally, the present invention arranges a push bar on the second cutting knife. When the second cutting knife cuts the frozen raw beef fat to the bottom, the push bar pushes the particles cut from the front in the conveying direction under the inertia of the counterweight block, and the second cutting knife body blocks the influence on the frozen raw beef fat strips on the rear side, thereby separating the fascia between the particles during the rapid cutting of the second cutting knife. Through the fascia separation design for three cuts, the present invention can effectively ensure the quality of the cut product under the premise of ensuring the cutting efficiency.

[0014] 3. There may be adhesion in some areas between the plastic-sealed frozen raw beef fat and the packaging bag. In order to avoid this situation, the prior art usually adopts multiple cuts and then uses a hook-tooth arrangement to grab the packaging bag. This method may not be thorough when unpacking some of the frozen raw beef fat, for example, the hook teeth may break the packaging bag or some packaging debris may remain on the frozen raw beef fat. The present invention adopts the method of first inflating (using gas to drive the plastic packaging film to expand) to drive the plastic packaging bag to be completely separated from the frozen raw beef fat, and then cuts horizontally, and then uses the adsorption part to adsorb the plastic packaging film at the bottom. Finally, the raw beef fat is pushed by the push plate. Due to the strong adsorption effect of the adsorption part, the plastic packaging bag will be retained on the adsorption part. In the process of pushing the frozen raw beef fat by the push plate (the bag rolling roller of the push plate continuously rolls into the rear packaging bag to squeeze the frozen raw beef fat out of the packaging bag, similar to squeezing toothpaste), the bottom area where the plastic packaging film and the frozen raw beef fat may be adhered will also be forcibly separated (the bottom area is not separated during the inflation separation, and the bag rolling roller cooperates with the adsorption effect of the adsorption part to separate during pushing). The bag rolling pushing design avoids the problem of debris retention in the existing technology and ensures the unpacking efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0041] like Figures 1 to 23 As shown, this embodiment includes a conveying unit, an unpacking unit and a cutting unit, wherein the conveying unit is used to convey the frozen raw beef fat packaged in a plastic bag to the unpacking unit, the unpacking unit is used to remove the outer plastic packaging bag of the frozen raw beef fat, and push the removed frozen raw beef fat into the cutting unit, and the cutting unit cuts the frozen raw beef fat and then outputs the frozen raw beef fat blocks through the conveying unit.

[0042] The conveying unit includes a first conveyor belt 1 and a second conveyor belt 4, wherein the first conveyor belt 1 is responsible for conveying the plastic-sealed frozen raw beef fat to the unpacking unit. The width of the first conveyor belt 1 matches the packaging setting of the frozen raw beef fat (its width matches the length of the frozen raw beef fat), and guard plates are arranged on both sides thereof. The guard plates on both sides can restrain the movement of the frozen raw beef fat during the conveying process of the frozen raw beef fat (for convenience of cutting and conveying position positioning, the frozen raw beef fat is frozen in a rectangular plate state), and the first conveyor belt 1 is also provided with a cutting assembly on the side close to the unpacking unit, and the cutting assembly includes an inflation plate 12 and a telescopic cutting knife 16, and the inflation plate A plurality of barbed tubes 14 are provided at the bottom of 12, and the barbed tubes 14 are connected to an air pump. The first conveyor belt 1 sequentially conveys the plastic-sealed frozen raw beef fat to the bottom of the air-filled plate 12, and the air-filled plate 12 is provided with a second telescopic rod 13. When the first conveyor belt 1 conveys the plastic-sealed frozen raw beef fat to the bottom of the air-filled plate 12, the air-filled plate 12 penetrates into the plastic-sealed packaging bag of the frozen raw beef fat under the push of the second telescopic rod 13, and rapidly fills the plastic-sealed packaging bag with nitrogen. The barbed tubes 14 separate the frozen raw beef fat from the plastic-sealed packaging bag through nitrogen (the gas expands the packaging bag, and then separates it), so as to facilitate subsequent unpacking. After the air-filled plate 12 is inflated, the first conveyor belt 1 continues to convey the plastic-sealed frozen raw beef fat backward. The first conveyor belt 1 is provided with a telescopic cutter 16 on the rear side of the inflation plate 12 (the cutter used in the existing unpacking process of frozen raw beef fat is usually a fixed cutter, which is arranged on the path through which the plastic-sealed frozen raw beef fat passes, but the surface of the frozen raw beef fat in the frozen state is usually not a regular plane state, which makes some packages After passing through the fixed cutter, some plastic bags in the recessed positions of the frozen raw beef fat are not cut open, which affects the subsequent processing. The use of the telescopic cutter 16 can effectively solve this problem). During the transportation of the plastic-sealed frozen raw beef fat, the telescopic cutter 16 can cut an opening horizontally on one side thereof to facilitate further subsequent unpacking processing.

[0043] The first conveyor belt 1 conveys the plastic-sealed frozen raw beef fat with an opening to the unpacking unit. The unpacking unit includes a push plate 17, an unpacking table 2 and an air suction component. The unpacking table 2 is provided with an adsorption portion 7. The first conveyor belt 1 conveys the plastic-sealed frozen raw beef fat to the adsorption portion 7. Due to the restraining effect of the guard plates on both sides of the first conveyor belt 1, the opening of the plastic-sealed frozen raw beef fat is always facing one side after being conveyed to the adsorption portion 7. In the embodiment, a cutting unit is provided on one side of the opening of the plastic-sealed package of the frozen raw beef fat, and a push plate 17 is provided on the opposite side of the opening of the plastic-sealed package of the frozen raw beef fat. The push plate 17 is directed to the A first telescopic rod 11 should be provided, and a push plate 17 is used to push the frozen raw beef fat into the cutting unit and out of the plastic-sealed packaging bag of the frozen raw beef fat. The adsorption part 7 is provided with a plurality of suction grooves, and the suction grooves are connected to a negative pressure chamber, and the negative pressure chamber is connected to a negative pressure suction port 6, and the negative pressure suction port 6 is connected to a vacuum negative pressure machine. The vacuum negative pressure machine continuously extracts the air inside the negative pressure chamber, and the negative pressure chamber then absorbs the air through the plurality of suction grooves of the adsorption part 7. When the frozen raw beef fat in the plastic-sealed state is conveyed to the adsorption part 7 by the first conveyor belt 1, the plurality of suction grooves of the adsorption part 7 adsorb the plastic-sealed packaging bag of the frozen raw beef fat onto the table top.

[0044] After the plastic-sealed packaging bag of the frozen raw beef fat is adsorbed, the push plate 17 at the rear side of the opening of the plastic-sealed bag pushes the frozen raw beef fat into the cutting unit. A bag rolling roller 18 is also arranged on the base plate of the push plate 17. The bag rolling roller 18 consists of two rollers arranged closely side by side. The bag rolling roller 18 is arranged in the middle position of the push plate 17 and is parallel to the push plate 17. A driving mechanism is arranged on one side of the bag rolling roller 18. The driving mechanism includes a first transmission box 19. The first transmission box 19 is provided with a third motor 10. The third motor 10 drives one of the rollers of the bag rolling roller 18 to rotate (the other roller is driven to rotate. The two rollers of the bag rolling roller 18 are made of high-friction elastic material, such as a rubber roller). A bag placing box 20 is arranged on the rear side of the push plate 17. The bag rolling roller 18 is connected to the bag placing box 20. A baffle is arranged on a longitudinal side of the push plate 17. A bag suction port 5 is provided on the top, and an opening is provided on the bag placing box 20 toward one side of the baffle (when the first telescopic rod 11 is fully retracted, the opening of the bag placing box 20 is connected to the bag suction port 5). In the process of the push plate 17 pushing the frozen raw beef fat in the plastic-sealed packaging bag into the cutting unit, the adsorption portion 7 hinders the advancement of the packaging bag, and at the same time, the roller continues to roll into the plastic-sealed packaging bag at the rear side, and the frozen raw beef fat is removed (similar to the process of squeezing paste). In addition, when the push plate 17 pushes the frozen raw beef fat into the cutting unit, the bag rolling roller 18 rolls the plastic-sealed packaging bag that the frozen raw beef fat has removed into the bag placing box 20. After the push plate 17 pushes the frozen raw beef fat to complete cutting, the first telescopic rod 11 is retracted to restore the push plate 17 to its initial position. At this time, the plastic-sealed packaging bag can be sucked out through the bag suction port 5 (the bag suction port 5 is connected to a suction pump).

[0045] The cutting unit is provided with a cutting box 3, which is provided with an inlet 31 and an outlet 32, wherein the first telescopic rod 11 pushes the frozen raw beef fat into the inlet 31 by means of a push plate 17, and is gradually pushed forward as the frozen raw beef fat is cut; the cutting box 3 is provided with a first cutting knife 41 inside the inlet 31, the first cutting knife 41 is vertically arranged, and vertical grooves 44 are respectively arranged on both sides of the first cutting knife 41, and the first cutting knife 41 is slidably arranged on the vertical grooves 44 on both sides, and the vertical grooves 44 on both sides are also provided with third telescopic rods 33, and the third telescopic rods 33 can drive the first cutting knife 41 to slide up and down, so that the first cutting knife 41 can cut the frozen raw beef fat, and the vertical grooves 44 on both sides of the first cutting knife 41 are respectively arranged on the vertical grooves 44. A first nut 45 is separately provided, and the vertical groove members 44 on both sides are respectively fixed on the corresponding first nuts 45. The first nuts 45 on both sides are also respectively provided with first screw rods 42, and the first nuts 45 on both sides are respectively engaged with the corresponding first screw rods 42. The first screw rod 42 has the same orientation as the first telescopic rod 11. The rotation of the first screw rod 42 can drive the first cutting knife 41 to slide in the pushing direction of the frozen raw beef fat. A back plate 43 is also provided behind the first cutting knife 41. After the first telescopic rod 11 pushes the frozen raw beef fat into the feed inlet 31, the first cutting knife 41 is pulled up under the drive of the third telescopic rod 33, and the frozen raw beef fat abuts on the back plate 43. The third telescopic rod 33 presses down the first cutting knife 41 to complete the cutting.

[0046] The first screw rods 42 on both sides are respectively provided with second transmission boxes 40, and the first screw rods 42 are respectively driven by the corresponding second transmission boxes 40. The two second transmission boxes 40 are provided with third rotating shafts 39. The third rotating shafts 39 are horizontally arranged and perpendicular to the first screw rods 42. The two second transmission boxes 40 are both connected to the third rotating shafts 39. The third rotating shafts 39 drive the two second rotating boxes to drive. The rotation of the third rotating shafts 39 can synchronously drive the two first screw rods 42 to rotate synchronously, and then drive the first nuts 45 on both sides to slide synchronously, so that the first cutting knife 41 can be smoothly displaced. It is worth mentioning that the rotation of the first screw rod 42 drives the first cutting knife 41 to slide on the first telescopic rod 11 (i.e., its pushing direction), which is used to control the distance between the first cutting knife 41 and the abutment plate 43. The distance between the two is the thickness of the frozen raw beef tallow cutting piece. By controlling the distance between the two, it can be used to preliminarily control the cutting particle size of the frozen raw beef tallow; in addition, in view of the problem of difficulty in cutting the fascia in the frozen raw beef tallow, as a preferred embodiment, the metal plate at the bottom of the first cutting knife 41 is fixed to the first nuts 45 on both sides, and the metal plate is slidably connected to the bottom plate of the feed inlet 31. During the downward cutting process of the first cutting knife 41, it can fit tightly with the front end edge of the metal plate (forming a cutting similar to scissors, the first cutting knife 41 cuts deeply at the edge of the metal plate, that is, over-cuts, so that the first cutting knife 41 is staggered with the metal plate, thereby completely shearing the frozen raw beef tallow fascia). When the first nut 45 drives the first cutting knife 41 under the rotation of the first screw rod 42, the metal plate moves synchronously with each other, ensuring the cutting effect of the first cutting knife 41 on the frozen raw beef tallow under different cutting particle sizes.

[0047] The cutting box 3 is also provided with a first rotating shaft 50 below the first cutting knife 41. The first rotating shaft 50 is horizontally arranged and parallel to the third rotating shaft 39. The first rotating shaft 50 is also coaxially provided with a main roller 46. The first rotating shaft 50 drives the main roller 46 to rotate. A plurality of annular blades 28 are overlapped and arranged on the main roller 46. The annular blades 28 are coaxial with the main roller 46 and can slide along the axis on the main roller 46 and cannot rotate relative to the main roller 46. Each annular blade cooperates with the main roller 46 to form a rolling cutter. The rolling cutter is also provided with a curved plate 53 on the side where the first cutting knife 41 cuts off the raw frozen beef fat slices. The curved plate 53 is used to cooperate with the rolling cutter to squeeze the frozen raw beef fat slices for cutting. The first rotating shaft 50 is also connected to a first motor 8. The first motor 8 is used to drive the main roller 46 to rotate, and the main roller 46 is used to drive the plurality of annular blades 28 to rotate. Each annular blade 28 is also provided with a distance adjustment mechanism, which includes a plurality of limit clamps 49, a scissors telescopic frame 38, a second nut 48 and a second screw rod 47. Each layer of annular blades 28 on the main roller 46 is provided with a limit clamp 49, and the limit clamp 49 is provided with a U-shaped part, and the U-shaped part opening faces the corresponding annular blade 28. Each annular blade 28 is slidably clamped in the opening of the U-shaped part. The plurality of limit clamps 49 are also respectively provided with a slip ring 54, and the plurality of slip rings 54 are correspondingly provided with a second screw rod 47. The plurality of slip rings 54 are sleeved on the second screw rod 47. The plurality of limit clamps 49 are also correspondingly provided with a scissors telescopic frame 38. Adjacent limit clamps 49 are rotatably arranged on the adjacently connected telescopic frame strips of the scissors telescopic frame 38 in sequence. The slip ring 54 corresponding to the first limit clamp 49 near one end of the first motor 8 is axially fixed relative to the second screw rod 47. The last limit clamp 49 at one end of the first motor 8 corresponds to the slip ring 54 which is the second nut 48 (the slip ring 54 between the two end slip rings 54 is a tubular ring, which can slide back and forth on the axis of the second screw rod 47). The second nut 48 is meshed and arranged on the second screw rod 47. The rotation of the second screw rod 47 can drive the second nut 48 to slide on the axis of the second screw rod 47. The sliding of the second nut 48 drives the multiple limit clamps 49 between the two end limit clamps 49 to slide through the scissors telescopic frame 38 to adjust the spacing between the multiple annular blades 28. The multiple limit clamps 49 are initially equidistantly arranged, and the telescopic characteristics of the scissors telescopic frame 38 can drive the multiple annular blades 28 to adjust the equidistant width, so that the hob formed by the main roller 46 can further control the cutting particle size of the frozen raw beef tallow (the spacing of the annular blades 28 is adjusted, and the cutting width changes).

[0048] Furthermore, a second screw rod 47 is rotatably arranged on the body of the cutting box 3 near one end of the first motor 8. The second screw rod 47 on this side is connected to the third rotating shaft 39 through a chain belt 37 (keeping the second screw rod 47 and the third rotating shaft 39 synchronous, and then the second screw rod 47 and the first screw rod 42 synchronous). The transmission of the second screw rod 47 can drive the third rotating shaft 39 to rotate through the chain belt 37. The rotation of the second screw rod 47 can drive the roller formed by the main roller 46 to adjust the cutting spacing. The third rotating shaft 39 can adjust the spacing between the first cutting knife 41 and the abutment plate 43. That is, the rotation of the second screw rod 47 can synchronously adjust the size of the particles cut by the first cutting knife 41 and the roller, so that the cutting box 3 can accurately and stably control the size of the frozen raw beef tallow particles. The second screw rod 47 is also connected to a clutch 36 on a side close to the first motor 8. The clutch 36 is provided with a second rotating shaft 52 as an input shaft. The second rotating shaft 52 is coaxially provided with a driven gear 35. The first rotating shaft 50 drives the clutch 36 to move through a gear set. The first rotating shaft 50 is provided with a driving gear 34, and the driving gear 34 is meshed with the driven gear 35 (that is, the second rotating shaft 52 obtains power through the first rotating shaft 50).

[0049] It is worth mentioning that when the roller formed by the first cutting knife 41 and the main roller 46 needs to adjust the cutting width, the clutch 36 engages the second screw rod 47 and transmits power to the second screw rod 47, the second screw rod 47 rotates and drives the third shaft 39 through the chain belt 37 (and then drives the first screw rod 42 to rotate synchronously, and synchronously adjusts the slice thickness of the first cutting knife 41). When the roller cooperates to adjust the spacing, the main roller 46 will synchronously drive the annular blade 28 to rotate, and the limit clamp 49 can drive the annular blade 28 to slide axially on the main roller 46 during the rotation of the annular blade 28, so as to prevent the limit clamp 49 from being stuck when statically adjusting the spacing between each annular blade 28 on one side of the annular blade 28. In addition, corresponding to the size of the cutting particles (the cutting particles become larger or smaller, and the blades shrink or expand), the first motor 8 controls the specific position of the first cutting knife 41 and each annular blade 28 by controlling the rotation direction and cooperating with the clutch 36. When the positions of the first cutting knife 41 and the annular blades 28 are controlled, the transmission between the clutch 36 and the second screw 47 is cut off, and the first nut 45 and the second nut 48 can respectively lock the specific positions of the first cutting knife 41 and the annular blades 28 to ensure the stability of the subsequent cutting particle size.

[0050] Specifically, as a preferred embodiment, each limit clamp 49 is arranged on the cutting side of the frozen raw beef tallow slice, and the corresponding curved plate 53 is provided with a sliding cutout corresponding to each limit clamp 49 (the limit clamp 49 can slide therein, and the extension direction of the cutout is consistent with the axial direction of the second screw rod 47), and one side of the U-shaped part of each limit clamp 49 is arranged on the side of the hob, and the U-shaped part of each limit clamp 49 is sharpened at one end close to the first cutting knife 41, so that the fascia between the frozen raw beef tallow slice cut by the hob and the gap of the curved slice can be forcibly cut and separated at the sliding connection position between the annular blade 28 and the limit clamp 49, and form an independent frozen raw beef tallow strip, thereby preventing the frozen raw beef tallow strips with fascia adhesion formed by the hob cutting, which affects the quality of the final frozen raw beef tallow particles.

[0051] The conveying unit is further provided with a second conveyor belt 4 below the cutting box 3. The conveying direction of the second conveyor belt 4 is the same as that of the first screw rod 42. The frozen raw fat is cut by the roller formed by the first cutting knife 41 and the main roller 46 to form a strip of raw fat and is conveyed to the second conveyor belt 4. The placement direction of the strip of frozen raw fat will be the same as that of the conveying direction of the second conveyor belt 4. The cutting box 3 is further provided with a second cutting knife 24 laterally above the second conveyor belt 4. Sliding clips 29 are further provided at both ends of the second cutting knife 24. Both ends of the second cutting knife 24 are arranged in the sliding clips 29. The second cutting knife 24 can slide up and down in the sliding clips 29. Both ends of the second cutting knife 24 are also rotatably connected with connecting clips Rod 23, the other end of the connecting rod 23 is rotatably connected to the eccentric shaft 22 (the eccentric shaft 22 is arranged above the second cutting knife 24), the eccentric shaft 22 is parallel to the third rotating shaft 39, the eccentric shaft 22 is fixed on the first transmission wheel 21, the axis of the first transmission wheel 21 is parallel to the axis of the eccentric shaft 22, the first transmission wheel 21 is connected to the second motor 9, the second motor 9 drives the eccentric shaft 22 to rotate through the first transmission wheel 21, the eccentric shaft 22 makes a circular motion around the axis of the first transmission wheel 21, and drives the connecting rod 23 to move up and down, the connecting rod 23 drives the second cutting knife 24 to slide up and down in the sliding clamp 29, and cooperates with the frozen raw beef tallow strips transported by the second conveyor belt 4 to cut the frozen raw beef tallow strips.

[0052] Specifically, as a preferred embodiment, a recessed portion is provided on the side of the second cutting knife 24 away from the annular blade 28, and a push strip 25 is provided in the recessed portion. The push strip 25 is arranged horizontally and parallel to the second cutting knife 24. The push strip 25 is arranged in the recessed portion (the push strip 25 can be accommodated in the recessed portion, so that the cutting surface of the second cutting knife 24 cutting the frozen raw beef fat strip does not hinder the cutting of the second cutting knife 24), and the push strip 25 is arranged close to the cutting edge of the second cutting knife 24. A rotatable fourth rotating shaft 30 is also provided at the vertical upper end of 24, the fourth rotating shaft 30 is parallel to the second cutting knife 24, the fourth rotating shaft 30 is connected to the push bar 25 through spokes, the second cutting knife 24 is also provided with a coil spring tube 27 on both sides thereof, a coil spring is provided inside the coil spring tube 27, the fourth rotating shaft 30 is connected to the coil spring tube 27 through the coil spring, both side ends of the fourth rotating shaft 30 continue to extend, and both side ends are also connected to counterweight blocks 26, and the counterweight block 26 is arranged on the side of the second cutting knife 24 close to the annular blade 28. The second motor 9 drives the second cutting knife 24 to cut the frozen raw beef fat strips into particles. During the cutting process, unlike the fascia separation setting of the rolling knife formed by the first cutting knife 41 and the main roller 46, when the second cutting knife 24 cuts the frozen raw beef fat strips to the bottom, a small amount of fascia silk or net may adhere to the bottom, causing the particles to adhere. After the second cutting knife 24 behind the pusher 25 cuts the frozen raw beef fat strips, the pusher 25 will expand relative to the second cutting knife 24 under the inertia of the counterweight block 26 (the second cutting knife 24 The up and down sliding cutting speed will be much higher than that of the first cutting knife 41. The slices cut by the first cutting knife 41 need to be cut by many cuts of the second cutting knife 24. The pause when the second cutting knife 24 cuts to the bottom can make the counterweight block 26 have a large inertia force. The counterweight block 26 drives the push strip 25 to open through the inertia force. After the second cutting knife 24 rises, the coil spring set on the second cutting knife 24 makes the counterweight block 26 return to its initial position), pushing the particles cut by the second cutting knife 24 forward. If there are fascia fibers or nets at the bottom of the particles, the pushing process can separate the fascia of the frozen raw beef tallow particles.

[0053] Furthermore, by controlling the rotation speed of the second motor 9 in coordination with the conveying speed of the second conveyor belt 4, the cutting width of the cut frozen raw beef tallow strips can be controlled, and ultimately the particle size of the cut frozen raw beef tallow strips can be controlled. In addition, the second conveyor belt 4 is also provided with a monitoring head 15, and the monitoring head 15 is used to detect whether there are packaging debris in the frozen raw beef tallow particles on the second conveyor belt 4 (in order to prevent the packaging bag from mixing into the raw beef tallow particles, the existing frozen raw beef tallow is usually packaged in a blue plastic packaging bag, so that the packaging bag debris mixed into the frozen raw beef tallow can be found at the first time. Therefore, the monitoring head 15 can perform color recognition to detect whether there are plastic packaging bag debris mixed in the cut frozen raw beef tallow particles).

[0054] It is worth noting that the embodiment controls the width of the first cutting knife 41 and the abutment plate 43, the width of each annular blade 28, the cutting speed of the second cutting knife 24 and the speed of the second conveyor belt 4 through a controller, so as to customize the particle size of the cut frozen raw beef tallow. This is a conventional technical means and is not within the feature scope of this embodiment, and the embodiment is only briefly mentioned here.
