Description
Technical Field
[0001] The invention relates to the field of crushing equipment, in particular to a crushing mixer for crushing meat. Background Art
[0002] Currently, there are two types of small meat grinders. One type uses a motor to drive the blade or meat grinder to rotate at high speed, generating powerful cutting and mixing forces. The other type uses a screw. When the meat is put into the feed port of this type of meat grinder, the meat is gradually transported, pressurized, and cut into small pieces under the action of the screw. However, these two types of grinders have their own disadvantages.
[0003] First of all, the blade-type meat grinder cuts by high-speed rotation of the blade, which makes a lot of noise, is prone to heat up, and has poor mixing continuity. In addition, blade wear can cause the blade to become blunt, reducing the effect or resulting in uneven meat filling, and is less convenient.
[0004] Secondly, compared with the motor-driven rotary blade meat grinder, the screw meat grinder relies on the pushing and squeezing of the screw in conjunction with the sharpening of the blade to grind the meat, and has better continuity. However, for some meats with a harder texture or more fascia, the screw is often easily entangled. In addition, if too much meat is put in at one time, or the shape of the meat is irregular, it will easily cause blockage during the screw pushing process, and the meat needs to be stirred independently after grinding, which is inconvenient to use.
[0005] In summary, both of the above-mentioned two meat grinders have certain drawbacks, and both require the meat to be cut in advance before being put in. Among them, the screw meat grinder often requires personnel to continuously apply pressure during the feeding process to ensure the best efficiency, otherwise it will be blocked and unable to feed, affecting the actual use effect. Based on this, this scheme proposes a crushing mixer for crushing meat to solve the above problems. Summary of the invention
[0006] The purpose of the present invention is to solve the problems of poor stirring effect, easy clogging, troublesome feeding and the need to pre-cut the whole meat in the current small meat grinder, resulting in low efficiency, and to propose a crushing and mixing machine for crushing meat.
[0007] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a crushing and mixing machine for crushing meat, comprising a meat mincing module and a feeding module and a cover respectively installed at both ends thereof, and a driving assembly is arranged at the bottom of the cover, the meat mincing module comprises a conical cylinder and a variable pitch screw directly driven by the driving assembly therein, and a grinding knife and a perforated plate are sequentially penetrated at the bottom end of the variable pitch screw;

[0009] The elastic constraint sheet reciprocates up and down with the rotating body, is blocked and gathered when moving up, and spreads and squeezes the meat pieces when moving down to contact the variable pitch screw for pressure and crushing.
[0010] As a further description of the above technical solution: the variable pitch screw rotates in a penetrating manner on the inner wall of the conical barrel, and the two ends of the variable pitch screw are arranged in a rectangular shape, the bottom end of the variable pitch screw is rotated in a penetrating manner on the orifice plate, and the grinder is embedded in the bottom end of the variable pitch screw and fits the orifice plate.

[0012] As a further description of the above technical solution: the feeding module also includes a hopper that cooperates with the top thread of the conical barrel, the seat body is fixed on the top of the hopper, the bottom end of the spring is fixed on the inner wall of the seat body, the top pin passes through and is fixed on the top of the inner wall of the seat body, and its bottom end is provided with a slot that engages with the top of the variable pitch screw, the top of the spinning body is arranged in an inclined shape, and the inner wall of the hopper is fixed with a plurality of fixed knives that fit with the cutter.
[0013] As a further description of the above technical solution: the drive assembly includes a driver and a stirring box fixed thereon, the inner wall of the stirring box is provided with a rotating seal for sealing the output end of the driver, and the output end of the driver is shaped in conjunction with the bottom end of the variable pitch screw.
[0014] As a further description of the above technical solution: the sealing cover includes a cover body that seals with the top of the stirring box, the inner wall of the cover body is equipped with an inner cover through a bearing, a plurality of stirring rods are rotatably installed on the surface of the inner cover, and the top ends of the plurality of stirring rods are commonly meshed with an inner gear ring, the inner gear ring is fixed to the inner wall of the cover body, a plurality of scrapers are integrally formed on the inner wall of the inner cover, and a plurality of scrapers are commonly fixed with a ferrule, and the inner wall of the ferrule is engaged with the bottom end of the variable pitch screw.
[0015] As a further description of the above technical solution: the top of the cover body is threadedly matched with the bottom end of the conical cylinder, and the cover body and the threaded cylinder cooperate to press and hold the limiting orifice plate, and the scraper slides on one side of the orifice plate.
[0016] As a further description of the above technical solution: the conical tube is narrow at the top and wide at the bottom, and its inner wall is arranged in an inclined wavy shape.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0018] The inclined top of the rotator cooperates with the inclined surface of the ejector pin to form a reciprocating lifting motion under the support of the spring, driving the elastic constraint sheet to move up and down periodically. When the elastic constraint sheet moves upward, the meat pieces piled up around it squeeze the edge of the elastic constraint sheet due to gravity, forcing it to shrink and gather; when it moves downward, the elastic constraint sheet unfolds and spreads flat, providing a support platform for the meat pieces and pushing the meat pieces toward the variable pitch screw through the lateral expansion force generated by deformation recovery. This method realizes dynamic adjustment of material stacking density and avoids the occurrence of material jamming caused by static stacking. At the same time, it utilizes the bidirectional force of vertical force and lateral thrust generated by elastic deformation. When it moves upward, the bidirectional force applied by elastic tension applies pressure to the meat pieces around it. When it moves upward, multiple piled meat pieces are squeezed and moved, destroying the original stacking state, so that the meat pieces can move downward to avoid material jamming. Under the subsequent tension, pressure can be applied to the meat pieces below, thereby improving the conveying efficiency of the variable pitch screw. Combined with intermittent downward pressing operation, excessive material pressing of the variable pitch screw is avoided. Compared with traditional spiral forced propulsion or vibration anti-blocking solutions, this design realizes adaptive anti-blocking with a very simple mechanical structure, which is particularly suitable for processing fresh meat with uneven fiber content and achieves industrial-grade anti-jamming performance in portable devices.
[0019] When the driver drives the variable pitch screw to rotate, it drives the spinner to rotate synchronously, and the spinner drives the cutter to rotate. When the cutter rotates, it cooperates with the fixed knife to cut the meat into pieces. At the same time, it drives the elastic constraint sheet to reciprocate up and down under the cooperation of the spring and the ejector pin. The elastic constraint sheet moves up and is blocked by the meat piece and gathered. When it moves down, it spreads and presses the meat piece to contact the variable pitch screw. The variable pitch screw cuts the meat piece and pressurizes it to form meat stuffing through the grinder and the orifice plate, and is stirred by the cover. In this way, the whole meat is pre-cut. At the same time, the meat piece can be intermittently pressed down by the elastic constraint sheet, so that the variable pitch screw can be kept to continuously and stably transmit the meat piece. After the meat piece is crushed in cooperation with the grinder and the orifice plate, the crushed minced meat and seasoning are stirred under the action of the cover.
[0020] This method saves energy and improves work efficiency without the need for pre-cutting the meat. The meat blocks are pressurized using an intermittent downward pressure method combined with continuous conveying and pressurization by a variable pitch screw to achieve high-efficiency continuous crushing. There will be no problem of meat blockage during continuous crushing. The cut meat blocks are shorter and are less likely to have fascia entanglement. Overall, this method has made significant progress compared to traditional solutions. At the same time, this method can achieve direct stirring after mincing the meat, and does not require manual stirring compared to traditional methods, making it more convenient to use.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0035] like Figure 1 - Figure 8As shown, the present invention provides: a meat crushing and mixing machine, comprising a meat mincing module 10 and a feeding module 20 and a cover 30 respectively installed at both ends thereof, and a driving assembly 40 is arranged at the bottom of the cover 30, the meat mincing module 10 comprises a conical cylinder 11 and a variable pitch screw 12 therein directly driven by the driving assembly 40;
[0036] Specifically, Figure 5 As shown, the variable pitch screw 12 is rotated in a penetrating manner on the inner wall of the conical cylinder 11, and the two ends of the variable pitch screw 12 are arranged in a rectangular shape, the bottom end of the variable pitch screw 12 is rotated through and arranged on the orifice plate 14, and the grinder 13 is embedded in the bottom end of the variable pitch screw 12 and fits on the orifice plate 14. By setting the variable pitch screw 12, a composite compression field is formed by changing the pitch and the diameter to achieve nonlinear extrusion force growth, so that the end pressure of the variable pitch screw 12 reaches 8 times that of the initial section, and compared with the equal pitch screw, the firmness of the meat filling is increased by 40% and the muscle fiber damage rate is reduced by 15%. The bottom end of the variable pitch screw 12 is successively penetrated by the grinder 13 and the orifice plate 14;
[0037] Compared with the motor-driven rotary blade meat grinder, the current screw-type meat grinder relies on the pushing and squeezing of the screw in conjunction with the grinder 13 to grind the meat, which has better continuity. However, for some meats with a harder texture or more fascia, it is often easy to get entangled with the screw. In this solution, the whole meat is cut by the cooperation of the cutter 29 and the fixed knife 22 to reduce the continuity of the fascia. At the same time, when the meat piece enters the conical cylinder 11 and is pressurized by the variable pitch screw 12, the meat piece contacts the inner wall of the wavy conical cylinder 11, so that the meat piece is continuously filled into its wavy groove under the action of pressure and is cut off accordingly. If there is fascia in this process, it will be separated from the meat piece and balled until it is transported to the bottom end and sheared by the grinder 13 and the orifice plate 14, which can effectively prevent the fascia from being entangled with the variable pitch screw 12 in a spreading state.
[0038] In addition, if too much meat is put into the current screw meat grinder at one time, or the shape of the meat is irregular, it will easily cause blockage during the screw pushing process, and the meat needs to be stirred independently after being minced, which is inconvenient to use. When the variable pitch screw 12 of this scheme rotates, it synchronously drives the spinner 24 to rotate, and the spinner 24 drives the cutter 29 to rotate. When the cutter 29 rotates, it cooperates with the fixed knife 22 to cut the meat into pieces. At the same time, it drives the elastic constraint sheet 26 to reciprocate up and down with the cooperation of the spring 28 and the top pin 27. The elastic constraint sheet 26 moves upward and is blocked by the meat piece and gathered. When it moves downward, it spreads and presses the meat piece down to contact the variable pitch screw 12. The top of the spiral leaf of the variable pitch screw 12 is sharp, which can further cut the pressed meat piece and then transmit it for pressurization, and this process can avoid blockage caused by too much meat.
[0039] The feeding module 20 includes a spinner 24 that rotates synchronously with the variable pitch screw 12, a top pin 27 slides on the top of the spinner 24, a spring 28 is arranged on the surface of the spinner 24, an elastic constraint sheet 26 is arranged on the arc-shaped side wall of the spinner 24, and a cutter 29 is installed on the surface of the spinner 24 through a support assembly 23;
[0040] At present, meat grinders that use blades to cut and stir at high speed are noisy, easy to heat up, have poor stirring continuity, and the wear of the blades will lead to reduced effect after the blade becomes blunt or uneven meat filling, which is less convenient. This solution does not require a faster rotation speed for crushing, so that the noise is small, and the cutting is mainly based on shear force, and the sharpness of the grinder 13 has a limited effect on the cutting uniformity.
[0041] The elastic restraining sheet 26 reciprocates up and down with the rotating body 24. When moving upward, it is blocked and gathered. When moving downward, it spreads and squeezes the meat pieces to contact the variable pitch screw 12 for pressure crushing.
[0042] Specifically, Figure 6 As shown, the support assembly 23 includes a seat body 231 and an outer ring 232 fixed thereon, and the inner wall of the outer ring 232 is rotatably mounted with an inner ring 233 through a plurality of rollers. The inner ring 233 is arranged in a polygonal shape and partially fits and slides with the spinner 24, and the cutter 29 is fixed at the bottom of the inner ring 233. The support assembly 23 serves as a rotation support for the spinner 24, and the inner ring 233 on its surface can slide in accordance with the shape of the spinner 24. When the spinner 24 rotates, the inner ring 233 rotates on the inner wall of the outer ring 232 through the rotor, and the inner ring 233 rotates with the cutter 29. When the spinner 24 slides in the axial position, its surface is in a polygonal shape and fits with the inner ring 233, and when the power transmission is maintained during rotation, the spinner 24 can slide vertically back and forth without motion interference.
[0043] Specifically, Figure 6 As shown, the feeding module 20 also includes a hopper 21 that is threadedly matched with the top of the conical cylinder 11, a seat body 231 is fixed on the top of the hopper 21, the bottom end of the spring 28 is fixed on the inner wall of the seat body 231, a top pin 27 is passed through and fixed on the top of the inner wall of the seat body 231, and a slot 25 is provided at the bottom end thereof for engaging with the top of the variable pitch screw 12, the top of the rotator 24 is arranged in an inclined shape, and a plurality of fixed knives 22 that are in contact with the cutter 29 are fixed on the inner wall of the hopper 21.
[0044] Specifically, Figure 3As shown, the drive assembly 40 includes a driver 41 and a stirring box 42 fixed thereon, and the inner wall of the stirring box 42 is provided with a rotating seal 43 for sealing the output end of the driver 41, and the output end of the driver 41 is shaped to fit with the bottom end of the variable pitch screw 12. By adopting the driver 41, the driver 41 is a reduction motor with a built-in planetary gear, and also includes electronic components such as an electric control board, which is used to provide high-torque and low-speed power, and its output end can fit with the bottom end of the variable pitch screw 12 to maintain transmission, and when the bottom end of the variable pitch screw 12 is inserted, power transmission is realized.
[0045] Specifically, Figure 4 As shown, the cover 30 includes a cover body 31 which is sealed with the top of the stirring box 42, an inner cover 32 is installed on the inner wall of the cover body 31 through a bearing, a plurality of stirring rods 35 are rotatably installed on the surface of the inner cover 32, and the top ends of the plurality of stirring rods 35 are commonly meshed with an inner gear ring 36, the inner gear ring 36 is fixed to the inner wall of the cover body 31, a plurality of scrapers 33 are integrally formed on the inner wall of the inner cover 32, and a plurality of scrapers 33 are commonly fixed with a ferrule 34, and the inner wall of the ferrule 34 is embedded with the bottom end of the variable pitch screw 12. The ferrule 34 inside the cover 30 can rotate slowly along with the variable pitch screw 12, and during the slow rotation, it can scrape the crushed meat filling on the orifice plate 14 with the scraper 33. At the same time, when the inner cover 32 rotates along with the scraper 33, the stirring rod 35 thereon slowly revolves, and the gear at the top of the stirring rod 35 can mesh with the inner gear ring 36, realizing rapid rotation, and then realizing stirring, so that the meat filling can be mixed with the added ingredients.
[0046] Specifically, Figure 2 and Figure 4 As shown, the top of the cover body 31 is threadedly matched with the bottom end of the conical cylinder 11 , and the cover body 31 and the threaded cylinder cooperate to press and hold the limiting orifice plate 14 , and the scraper 33 slides on one side of the orifice plate 14 .
[0047] The installation is performed by threaded engagement, which facilitates assembly and disassembly. The cover body 31 and the conical cylinder 11 can be threadedly engaged to press the orifice plate 14, and the orifice plate 14 can be taken out after separation.
[0048] Specifically, Figure 3 and Figure 7 As shown, the conical barrel 11 is narrow at the top and wide at the bottom, and its inner wall is arranged in an inclined wave shape. The feeding end of the conical barrel 11 is narrow, and the discharging end is wide, which can meet the pitch and diameter changes of the variable pitch screw 12 during the feeding process and achieve the best pressurization state.
[0049] At the same time, the inner wall of the conical cylinder 11 is wavy and fits the sliding of the variable pitch screw 12. The meat piece is relatively soft and will deform under pressure and fill the shape of the inner wall of the conical cylinder 11, so that the variable pitch screw 12 can cut it during its rotation. In particular, the fascia on the surface of the meat piece can be kneaded into a ball in this process, which makes it convenient to transport it to the sharpening position 13 for processing and avoids the situation of being entangled in the variable pitch screw 12.
[0050] When the present solution is in use, the output end of the driver 41 passes through the rotary seal 43 and engages with the bottom end of the variable pitch screw 12, and rotates synchronously with it at a slow speed. When the variable pitch screw 12 rotates slowly, it drives the top spinner 24 to rotate, wherein the spinner 24 drives the inner ring 233 on the surface to rotate synchronously, and when the inner ring 233 rotates, it drives the cutter 29 to rotate, and when the cutter 29 and the fixed knife 22 are staggered, the whole meat is cut into pieces, so that the whole meat can be directly put in without the need for pre-cutting operation;
[0051] After the meat piece falls, it contacts the elastic constraint sheet 26. As the spinner 24 rotates, its inclined top end is always in contact with the ejector pin 27 under the support of the spring 28, and the spinner 24 repeatedly compresses the spring 28 in the reciprocating up and down motion under the action of the inclined surface of its top end. In this process, the spinner 24 reciprocates up and down with the elastic constraint sheet 26 at the same time, wherein a lot of meat pieces are piled up around the elastic constraint sheet 26. When it moves up, the meat pieces squeeze the elastic constraint sheet 26 to gather and shrink. When it moves down, the elastic constraint sheet 26 contacts the meat pieces, causing them to gradually spread out, and squeezes the meat pieces toward the variable pitch screw 12. At this time, the elastic constraint sheet 26 intermittently squeezes the meat pieces toward the variable pitch screw 12 during the up and down reciprocating process to avoid the meat pieces from getting stuck.
[0052] The pitch of the variable pitch screw 12 gradually decreases from the feeding end to the discharging end, and the diameter of the screw gradually increases, which generates a gradually increasing extrusion force on the material, so that the material can move more smoothly in the discharging direction. Combined with the gradual expansion of the diameter of the conical barrel 11 during transmission, the conveying effect of the meat blocks is increased until the meat blocks are squeezed at the position of the grinder 13, and the grinder 13 and the orifice plate 14 form a shear force to break the meat blocks into meat fillings.
[0053] At the same time, the variable pitch screw 12 rotates with the ferrule 34 based on the shape of the bottom end. When the ferrule 34 rotates, the meat filling under the orifice plate 14 is scraped off and dropped by the scraper 33. The scraper 33 rotates with the inner cover 32 at the same time. The inner cover 32 rotates in the cover body 31 through the bearing. As the inner cover 32 rotates, the multiple stirring rods 35 rotatably mounted thereon revolve accordingly. At the same time, when the stirring rod 35 revolves, the inner gear ring 36 meshing at the top of the stirring rod 35 causes the stirring rod 35 to rotate on its own, thereby achieving the stirring of the meat filling.
[0054] When in use, the meat and other dishes or seasonings can be added together in a quantitative manner, without the need for other operations and management. After a period of time, a prepared meat filling product is formed. The overall continuity is high, the size is small and portable, and the raw materials can be directly put into the machine after cleaning. The operation is simple and convenient.
[0055] When necessary, the hopper 21 and the conical cylinder 11 can be separated separately by rotating the cover body 31 and the conical cylinder 11, so as to separate the cover body 31 from the meat mincing module 10 and the feeding module 20 from the meat mincing module 10. At the same time, the interference fit state of the cover body 31 and the stirring box 42 can be directly separated, and the whole can be easily cleaned after separation. The separation method is simple and quick. After separation, the variable pitch screw 12 can be taken out for convenient and thorough cleaning.
[0056] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
