Description

Technical Field

[0001] This invention relates to the field of meat pretreatment equipment technology, specifically to a meat raw material pretreatment system for ham sausage processing. Background Technology

[0002] Meat cutting and grinding is a core step in the pre-processing of ham sausage production. The cutting accuracy, adaptability to working conditions, and operational stability of the equipment directly determine the quality of the subsequent minced meat and the production efficiency of the entire production line. At present, a large number of technical solutions for cutting and grinding equipment used in the pre-processing of ham sausage raw materials have been disclosed, such as those with publication numbers CN209106098U, CN115299480A, and CN217160946U. The aforementioned patents and similar conventional meat pre-processing equipment in the industry generally adopt a fixed-spacing combination blade structure, and the blade position cannot be changed according to the feeding state. In actual continuous production, the feed rate of the production line often fluctuates. When the instantaneous feed rate increases and the material accumulates above the blade assembly, the fixed-spacing blade assembly cannot change the shearing space. The material passes through quickly and is subjected to insufficient shearing, which easily leads to problems such as large particle size and uneven meat particles. At the same time, a large amount of material concentrates and squeezes the blades and the main shaft, which increases the equipment load sharply and is very likely to cause machine jamming and material jamming failures. It also accelerates blade wear and shortens the service life of the equipment. Existing equipment with adjustable blade spacing mostly relies on manual adjustment during shutdown or the addition of independent motors and electrical control components. This not only involves cumbersome operation and an inability to respond to dynamic changes in the feed rate in real time, but also results in significant adjustment lag and increases the overall structural complexity of the equipment, raising the probability of failure and subsequent maintenance costs. Furthermore, traditional equipment lacks an active unloading protection structure against material accumulation. The weight and pressure of excessive material are directly applied to the cutting blades, further exacerbating the risk of equipment overload and making it unsuitable for the requirements of large-scale continuous production of ham sausages. Therefore, a meat raw material pretreatment system for ham sausage processing is proposed, which can adaptively adjust the blade spacing according to the feed rate. During high flow rates, the spacing automatically decreases to improve the crushing effect. The entire process requires no manual intervention, effectively improving overall production efficiency and equipment operational stability. Summary of the Invention

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] To adaptively adjust the blade spacing according to the feed rate, and automatically reduce the spacing to improve the crushing effect at high flow rates, as one embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the meat raw material pretreatment system for ham sausage processing according to the present invention includes a shell 1. A feeding port is provided at the top of the shell 1, and a baffle ring 2 is fixedly installed inside the feeding port. A conical feeding hopper 3 is slidably assembled on the outside of the baffle ring 2. A cutting sleeve 4 is provided inside the shell 1 below the conical feeding hopper 3. A discharge sleeve 5 is fixedly connected to the bottom end of the cutting sleeve 4. A horizontally arranged feeding structure is connected to the lower end of the discharge sleeve 5. A drive spindle 6 is vertically provided inside the cutting sleeve 4. A fixed cutting blade 12 is fixedly installed at the bottom end of the drive spindle 6. A sliding bushing 7 is slidably sleeved on the drive spindle 6. A movable cutting blade 8 is assembled on the outer wall of the sliding bushing 7. A transmission component for driving the sliding bushing 7 to slide up and down is installed at the top of the drive spindle 6. The outer side of the cutting sleeve 4 is connected to the outer wall of the conical feed hopper 3 through multiple sets of circumferentially arranged weighing and pressure supply components. Several sets of telescopic support components are installed circumferentially on the outer wall of the conical feed hopper 3. The weighing and pressure supply components are respectively connected to the transmission components and the telescopic support components through oil circuits.

[0019] When in use, the meat raw material to be processed is put into the feeding port at the top of the shell 1. If the feeding amount is within the normal range, the load on the conical feeding hopper 3 is small, and the weighing and pressure supply component and the telescopic top support component are in the initial state. The movable cutting blade 8 and the fixed cutting blade 12 maintain a preset fixed distance. After the equipment is started, the main shaft 6 is driven to rotate, which synchronously drives the sliding bushing 7 to rotate together. The fixed cutting blade 12 and the movable cutting blade 8 rotate synchronously, and continuously shear and crush the meat raw material falling from the conical feeding hopper 3 into the cutting sleeve 4. The crushed material is conveyed backward through the discharge sleeve 5. The equipment stably completes the raw material pretreatment operation under normal working conditions. The fixed blade group spacing can ensure that the material passes smoothly and the crushed particle size is uniform when feeding normally. When the instantaneous feed rate increases and the material accumulates in the conical feed hopper 3, the material's own weight causes the conical feed hopper 3 to slide downwards. The downward movement of the conical feed hopper 3 triggers the weighing and pressure supply component, which supplies pressure medium to the transmission component and the telescopic support component through the oil circuit. The transmission component drives the sliding bushing 7 to slide downwards along the drive shaft 6, reducing the distance between the movable cutting blade 8 and the fixed cutting blade 12, narrowing the material passage space, reducing the overall material falling velocity, extending the material cutting time, and increasing the shearing frequency and crushing force of the blades on large-flow materials. This effectively solves the problems of excessively fast material passage, insufficient shearing, and uneven particle size under large feed rates. The drive spindle 6 and the sliding bushing 7 always rotate synchronously, and the cutting action is not interrupted during the adjustment process, ensuring the continuity of operation. The blade spacing can be dynamically adjusted according to the feed rate. The crushing effect is enhanced under high flow conditions, ensuring that the meat particles are uniform under different feeding conditions, and adapting to continuous operation of the production line. The weighing and pressure supply component synchronously drives the telescopic top support component to move. The end of the telescopic top support component extends into the feed hopper to support and support the accumulated material, share the material's own weight and accumulation pressure, and prevent a large amount of material from concentrating and squeezing the cutting blade and drive spindle 6 below. This prevents the equipment from stalling or jamming, while also reducing the wear rate of the blade and spindle and extending the service life of the equipment. When the feed rate of the production line returns to normal and the material accumulation in the conical feed hopper 3 decreases, the overall load decreases accordingly. The weighing and pressure supply component automatically resets and extends, and drives the conical feed hopper 3 to reset upward. The transmission component drives the sliding bushing 7 and the movable cutting blade 8 to move upward back, and the blade spacing returns to the initial set value. The telescopic top support component retracts to the initial position simultaneously, and the equipment returns to the normal cutting condition. No manual intervention is required throughout the process, and it can adapt to the fluctuation of the feed rate in real time. After being thoroughly pulverized by the cutting blades, the meat is continuously conveyed to the feeding structure through the cutting sleeve 4 and the discharge sleeve 5. During the operation of the feeding structure, the meat is continuously conveyed on the one hand, and the initially pulverized meat is further squeezed and crushed on the other hand to meet the raw material requirements for ham sausage production. The processed meat is discharged from the end of the feeding structure. The entire set of equipment can adapt to fluctuations in the feed rate throughout the process, stably complete the raw material pretreatment process, and fully meet the needs of large-scale continuous production.

[0020] To improve the shearing frequency and pulverizing effect of high-flow-rate materials, for example, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the present invention also includes a transmission assembly comprising a first mounting plate 9 fixedly connected to the upper end of a drive spindle 6, a second mounting plate 10 fixedly connected to the upper end of a sliding bushing 7, and a return spring 11 connected between the first mounting plate 9 and the second mounting plate 10; a horizontally arranged support plate 13 fixedly connected to the upper part of the housing 1 via a connecting column 46, a drive motor 14 mounted on the support plate 13, and the output shaft of the drive motor 14 connected to the drive spindle 6; an adjusting plate 15 rotatably connected to the outer side of the sliding bushing 7, and a plurality of first hydraulic cylinders 16 installed between the support plate 13 and the adjusting plate 15, the first hydraulic cylinders 16 being connected to a weighing and pressure supply assembly via pipelines; and a meshing transmission assembly being provided between the drive spindle 6 and the sliding bushing 7 to achieve synchronous rotation.

[0021] During use, the drive motor 14 drives the drive spindle 6 to rotate continuously. The drive spindle 6 drives the sliding sleeve 7 to rotate synchronously through the meshing transmission component, so that the fixed cutting blade 12 and the movable cutting blade 8 operate synchronously and perform uniform cutting of the meat raw material that falls into the cutting sleeve 4. When the feed rate is stable within the normal range, the cone feed hopper 3 is under light load, the weighing and pressure supply component has no pressure output, the first hydraulic cylinder 16 remains in the retracted state, the adjusting plate 15 and the sliding bushing 7 are both in the initial position, the movable cutting blade 8 and the fixed cutting blade 12 maintain the standard blade distance, and the equipment continuously and stably completes the raw material shearing work. As the feed rate increases, the material accumulation causes the conical feed hopper 3 to move downward under pressure, triggering the weighing and pressure supply component to deliver hydraulic oil to the first hydraulic cylinder 16. The first hydraulic cylinder 16 pushes the adjusting plate 15 downward, and the adjusting plate 15 drives the sliding bushing 7 to move downward along the drive shaft 6. The movable cutting blade 8 moves downward synchronously, reducing the blade group distance between the movable cutting blade 8 and the fixed cutting blade 12. The larger the feed rate, the greater the downward movement of the conical feed hopper 3, the longer the extension stroke of the first hydraulic cylinder 16, the greater the downward movement of the sliding bushing 7, and the smaller the blade group distance. The reduced blade group distance can improve the shearing frequency and crushing effect of high-flow-rate materials, and prevent the problem of insufficient cutting and uneven particle size caused by the material passing through too fast. During the downward movement of the sliding bushing 7, the return spring 11 between the first mounting plate 9 and the second mounting plate 10 will be stretched, so that the return spring 11 stores elastic potential energy and stores force for subsequent reset action; at the same time, the meshing transmission assembly always ensures that the drive spindle 6 and the sliding bushing 7 rotate synchronously, and the adjustment process will not interrupt the cutting process, ensuring production continuity. When the feed rate drops, the load on the conical feed hopper 3 decreases and resets upwards. The pressure supply of the weighing and pressure supply component decreases, the first hydraulic cylinder 16 retracts, and the reset spring 11 releases its elastic potential energy, pulling the second mounting plate 10 and the sliding bushing 7 upwards. The movable cutting blade 8 moves upwards synchronously. When the feed rate drops back to the standard range, the blade spacing returns to the initial range. No manual intervention is required, and it can quickly adapt to the dynamic changes in the feed rate, further simplifying the equipment control structure and reducing the probability of failure.

[0022] For example, such as Figure 7 , Figure 8 , Figure 9 As shown, the present invention also includes a meshing transmission assembly comprising a spline shaft 17 and a spline sleeve 18. The spline shaft 17 is integrally disposed on the outer side of the drive spindle 6. The spline sleeve 18 matching the spline shaft 17 is fixed on the inner side of the upper end of the sliding sleeve 7. The spline shaft 17 and the spline sleeve 18 are in sliding engagement.

[0023] When the equipment is in use, the drive spindle 6 rotates, the spline shaft 17 meshes with the spline sleeve 18 inside the sliding sleeve 7, and the torque is transmitted to the sliding sleeve 7. The sliding sleeve 7 rotates synchronously with the drive spindle 6, ensuring that the fixed cutting blade 12 and the movable cutting blade 8 rotate at the same speed, so that the meat raw material is subjected to balanced force and the cutting is uniform and stable. When the feed rate changes, the first hydraulic cylinder 16 pushes the sliding sleeve 7 to move up and down along the drive shaft 6, and the spline sleeve 18 can slide axially along the spline shaft 17. The two always maintain a meshing state. While realizing the up and down displacement of the sliding sleeve 7 and adjusting the distance between the tool sets, there will be no interruption of power transmission or slippage, which is suitable for the needs of long-term continuous operation of the equipment.

[0024] To reduce the pressure on the fixed cutting blade 12 and the movable cutting blade 8, for example, such as Figure 3 , Figure 4 , Figure 7 As shown, the present invention also includes a telescopic top support assembly comprising multiple sets of second hydraulic cylinders 19. The second hydraulic cylinders 19 are fixed to the outer wall of the conical feed hopper 3. The piston rod of the second hydraulic cylinder 19 passes through the conical feed hopper 3 and is in a sealed sliding fit with the conical feed hopper 3. In the initial state, the end face of the piston rod of the second hydraulic cylinder 19 is flush with the inner wall of the conical feed hopper 3. The second hydraulic cylinder 19 is connected to the weighing and pressure supply assembly through a pipeline.

[0025] During use, when the feed rate increases sharply and the material accumulates in the conical feed hopper 3, the weighing and pressure supply component delivers hydraulic oil to the second hydraulic cylinder 19 through the pipeline, pushing the piston rod to extend into the conical feed hopper 3, supporting and lifting the accumulated meat material upwards. On the one hand, this distributes the overall weight of the material, reducing the pressure on the fixed cutting blade 12 and the movable cutting blade 8, preventing machine jamming and material jamming, and reducing wear on the blades and spindle. On the other hand, the lifting action can break up the clumps and piles of meat material, preventing local compaction and clumping, making the meat material more loose and uniform, facilitating subsequent cutting by the blades and improving the crushing quality. At the same time, after the material is appropriately lifted, the thickness of the material layer is controlled, preventing excessive accumulation that obstructs the blades and ensuring sufficient operating space for the blades. When the feed rate returns to normal, the conical feed hopper 3 is raised, the weighing and pressure supply component reduces the pressure supply, the second hydraulic cylinder 19 automatically retracts, and the piston rod end face of the second hydraulic cylinder 19 is flush with the inner wall of the feed hopper again. The entire process is automated and requires no manual intervention. It can repeatedly adapt to the dynamic changes in the feed rate and meet the needs of long-term continuous operation of the production line.

[0026] For example, such as Figure 4 , Figure 7 As shown, the present invention also includes a weighing and pressure supply assembly comprising multiple sets of pressure supply cylinders 20 vertically installed on the outer wall of the discharge sleeve 5, a horizontal fixing ring 21 fixed on the lower outer wall of the conical feed hopper 3, and the piston rod of the pressure supply cylinder 20 connected to the lower surface of the fixing ring 21; the pressure supply cylinder 20 is connected to the first hydraulic cylinder 16 and the second hydraulic cylinder 19 through pipelines.

[0027] When in use, as the feed rate increases, the conical feed hopper 3 moves downward under the weight of the material, pressing down the horizontal fixing ring 21, which in turn squeezes the piston rod of the pressure cylinder 20. The hydraulic oil of the pressure cylinder 20 is delivered to the first hydraulic cylinder 16 and the second hydraulic cylinder 19 through pipelines, providing stable hydraulic power for the adjustment of the blade spacing and the material support action. When the feed rate returns to normal, the load on the conical feed hopper 3 decreases, the pressure cylinder 20 resets and drives the conical feed hopper 3 to reset upwards, and the first hydraulic cylinder 16 and the second hydraulic cylinder 19 retract and reset in sequence. Pressure triggering and pressure relief are achieved by relying on the weight of the material itself. No additional sensors and electrical control components are required. It has a rapid response, low failure rate, and can work continuously for a long time, adapting to the working conditions of repeated fluctuations in the feed rate of the production line.

[0028] To prevent meat from remaining on the blade surface and in the gaps between the blades for extended periods, and to prevent material from accumulating and clumping, for example, such as Figure 6 , Figure 10 , Figure 11As shown, the present invention also includes an installation groove 22 formed on the inner side of the lower end of the sliding bushing 7, an installation ring 23 fixed on the lower outer side of the sliding bushing 7, and a horizontally arranged movable cutting blade 8 provided on the outer side of the installation ring 23; one end of the movable cutting blade 8 is connected to a drive shaft 24, and the drive shaft 24 passes through the installation ring 23 and extends into the installation groove 22. The first worm gear 25 is rotatably mounted in the mounting groove 22. The end of the transmission shaft 24 is fixedly connected to the first worm wheel 26, which meshes with the first worm gear 25. The first worm gear 25 has an axially oriented positioning hole 27 inside. The inner wall of the positioning hole 27 has a spiral guide groove 28. The upper end of the sliding bushing 7 has an axial sliding hole 29, which is connected to the mounting groove 22 vertically. The vertically arranged adjusting rod 30 is slidably mounted in the sliding hole 29. The upper end of the adjusting rod 30 is fixedly connected to the lower surface of the first mounting plate 9. The lower end of the adjusting rod 30 extends into the spiral guide groove 28. The bottom end of the adjusting rod 30 is fixed with a guide block 31 that slides with the spiral guide groove 28.

[0029] During use, under normal feeding conditions, the sliding bushing 7 is in the initial high position, and the movable cutting blade 8 maintains a horizontal state to carry out cutting operations. The horizontally arranged movable cutting blade 8 can perform all-round uniform shearing of the falling meat, ensuring smooth material passage and stable overall processing. When the amount of feed increases, the weighing and pressure supply component drives the first hydraulic cylinder 16 to extend, pushing the adjusting plate 15 to move the sliding bushing 7 downward as a whole. During the downward movement of the sliding bushing 7, the sliding hole 29 moves down synchronously with the sliding bushing 7, causing the guide block 31 at the bottom of the adjusting rod 30 to slide relative to the spiral guide groove 28 inside the first worm 25, driving the first worm 25 to rotate. The first worm gear 25 drives the first worm wheel 26 to rotate synchronously. The first worm wheel 26 drives the transmission shaft 24 to rotate, which in turn drives the movable cutting blade 8 at the end of the transmission shaft 24 to deflect synchronously. This causes the movable cutting blade 8 to gradually tilt downward from its initial horizontal state, which can change the direction of material falling and prevent meat from staying on the blade surface and in the gap between the blades for a long time, thus preventing material from accumulating and clumping. Secondly, the tilted blade surface can squeeze and crush the flowing meat and tendons, achieving secondary refinement processing outside of the main shearing process, further improving the uniformity of the meat. At the same time, the tilted structure can prevent a large amount of meat from being directly spread and piled up on the horizontal blade surface, preventing the thick layer of material from continuously pressing on the blade body, reducing the load on the blade, and eliminating damage such as blade deformation and chipping caused by material accumulation and squeezing, effectively protecting the cutting blade. When the feed rate returns to normal, the weighing and pressure supply component reduces the pressure supply. The reset spring 11 releases its elastic potential energy and pulls the sliding bushing 7 upward. During the upward movement of the sliding bushing 7, the adjusting rod 30 and the guide block 31 slide in the opposite direction along the spiral guide groove 28, driving the first worm gear 25 to rotate in the opposite direction. After being driven by the first worm wheel 26 and the transmission shaft 24, the movable cutting blade 8 gradually rotates back to its horizontal position, which can quickly adapt to changes in working conditions and continuously cycle.

[0030] For example, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes a feeding structure comprising a feeding pipe 32 connected to the lower end of the discharge sleeve 5, a spiral feeding shaft 33 assembled inside the feeding pipe 32, and an extrusion orifice plate 34 detachably installed at the end of the feeding pipe 32 that protrudes from the housing 1; a first pulley 35 is fixed to the lower end of the drive spindle 6, a protective shell 36 is fitted on the outside of the drive spindle 6, the first pulley 35 is housed inside the protective shell 36, a tapered guide surface is provided on the upper outer edge of the protective shell 36, and the protective shell 36 is positioned corresponding to the position of the discharge sleeve 5. A discharge port 37 is provided; a transmission rod 38 is vertically provided inside the housing 1, and multiple sets of bearing seats 39 are rotatably mounted on the transmission rod 38. The bearing seats 39 are fixedly connected to the inner wall of the housing 1 through a connecting rod 40; a second pulley 41 is fixed to the upper end of the transmission rod 38, and the first pulley 35 and the second pulley 41 are connected by a transmission belt 42; a second worm 43 is fixed to the lower end of the transmission rod 38, and a second worm wheel 44 is fixed to one end of the spiral feeding shaft 33. The second worm 43 and the second worm wheel 44 mesh with each other for transmission.

[0031] In use, the drive spindle 6 rotates continuously, and the first pulley 35 rotates synchronously. The first pulley 35 transmits power to the second pulley 41 through the transmission belt 42. The second pulley 41 drives the transmission rod 38 to rotate, and the second worm gear 43 on the transmission rod 38 rotates synchronously. The second worm gear 43 meshes with the second worm wheel 44, and the torque is further transmitted through the worm wheel and worm gear transmission, driving the spiral feeding shaft 33 to rotate. The meat material cut by the upper blade group falls smoothly into the feeding pipe 32 through the discharge sleeve 5. The rotating spiral feeding shaft 33 continuously pushes the material forward. The spiral blades can further stir and knead the meat material. The material is continuously squeezed forward under the action of the spiral thrust, and finally squeezed out from the extrusion plate 34 at the end of the feeding pipe 32. It is divided into meat particles of uniform size by the extrusion plate 34, completing the final forming process. The top of the protective shell 36 is provided with a conical guide surface, which can effectively prevent materials from accumulating on the upper surface of the protective shell 36, ensuring smooth material passage. At the same time, the materials can fall smoothly into the discharge sleeve 5 through the discharge port 37.

[0032] For example, such as Figure 2As shown, the present invention also includes a material blocking hopper 45 fixedly installed at the upper end of the housing 1, and the material blocking hopper 45 is arranged around the feeding port.

[0033] When meat is fed into the feeding port, the baffle 45 can effectively prevent the material from scattering in all directions, greatly reducing material waste, and at the same time preventing meat from dripping onto the outside of the equipment or the ground, keeping the production environment clean.

[0034] In use, the drive motor 14 is started, and the output shaft of the drive motor 14 drives the drive spindle 6 to rotate continuously. The drive spindle 6, through the meshing transmission between the spline shaft 17 and the spline sleeve 18, synchronously drives the sliding sleeve 7 to rotate together, so that the fixed cutting blade 12 and the movable cutting blade 8 operate synchronously. The raw meat to be processed is put into the feeding port at the top of the shell 1. The baffle ring 2 limits and blocks the material to prevent it from scattering. At the same time, it leaves room for the conical feeding hopper 3 to slide up and down. The baffle hopper 45 at the top of the shell 1 is arranged around the feeding port to further prevent the material from scattering in all directions, greatly reducing raw material waste and preventing meat from dripping outside the equipment, keeping the production environment clean. At the same time, it blocks the upper operating area of ​​the equipment, improving operational safety. The material falls into the conical feeding hopper 3 and then enters the cutting sleeve 4 below. When the feed rate is within the normal range, the load on the conical feed hopper 3 is small. The movable cutting blade 8 and the fixed cutting blade 12 maintain a preset fixed distance. The two sets of blades rotating synchronously continuously shear and crush the meat raw material falling into the cutting sleeve 4. The crushed material is conveyed backward through the discharge sleeve 5. The fixed standard blade distance can ensure that the material passes smoothly and the crushed particle size is uniform when feeding normally. When the instantaneous feed rate increases and the material accumulates in the conical feed hopper 3, the material's own weight drives the conical feed hopper 3 to slide down along the baffle ring 2, pressing down the horizontal fixing ring 21, which in turn squeezes the piston rod of the pressure cylinder 20. The hydraulic oil in the pressure cylinder 20 is delivered to the first hydraulic cylinder 16 and the second hydraulic cylinder 19 through pipelines. The pressure is triggered by the material's own weight, without the need for additional sensors and electrical control components. It has a rapid response, low failure rate, and can work continuously for a long time, adapting to the working conditions of repeated fluctuations in the feed rate of the production line. The piston rod of the first hydraulic cylinder 16 extends outward, pushing the adjusting plate 15 downward. The adjusting plate 15 drives the sliding bushing 7 to move downward along the drive shaft 6, and the movable cutting blade 8 moves downward synchronously, reducing the blade group distance between the movable cutting blade 8 and the fixed cutting blade 12. The larger the feed rate, the greater the downward movement of the conical feed hopper 3, the longer the extension stroke of the first hydraulic cylinder 16, the greater the downward movement of the sliding bushing 7, and the smaller the blade group distance. This narrows the material passage space, reduces the overall material falling velocity, extends the material cutting time, and increases the shearing frequency and crushing force of the blades on large-flow materials. This effectively solves the problems of excessively fast material passage, insufficient shearing, and uneven particle size under large feed rates. The cutting action will not be interrupted during the distance adjustment process, ensuring continuous operation. During the downward movement of the sliding bushing 7, the return spring 11 between the first mounting plate 9 and the second mounting plate 10 is stretched, allowing the return spring 11 to store elastic potential energy. Simultaneously, the sliding hole 29 moves downward synchronously with the sliding bushing 7, and the guide block 31 at the bottom of the adjusting rod 30 slides relative to each other along the spiral guide groove 28 inside the first worm 25, driving the first worm 25 to rotate. The first worm 25 drives the first worm wheel 26 to rotate synchronously, and the first worm wheel 26 drives the transmission shaft 24 to rotate, ultimately driving the movable cutting blade 8 to gradually tilt downward from the initial horizontal state. This changes the direction of material falling, preventing meat from staying on the blade surface and in the blade gap for a long time, and preventing material from accumulating and clumping. The tilted blade surface exerts a squeezing and kneading effect on the flowing meat and tendons, achieving secondary refinement processing outside of the main shearing process, further improving the uniformity of the meat. At the same time, it prevents a large amount of meat from being directly spread and piled up on the horizontal blade surface, preventing the thick layer of material from continuously pressing on the blade, reducing the load on the blade, and eliminating damage such as blade deformation and chipping caused by material accumulation and squeezing, effectively protecting the cutting blade. The second hydraulic cylinder 19 synchronously receives hydraulic oil, and the piston rod extends into the conical feed hopper 3, supporting and lifting the accumulated meat material upwards. On the one hand, this distributes the overall weight of the material, reduces the pressure on the fixed cutting blade 12 and the movable cutting blade 8, prevents jamming and material blockage, reduces wear on the blades and main shaft, and extends the service life of the core components of the equipment. On the other hand, the lifting action can break up the clumps and piles of meat material, prevent local compaction and clumping, and make the meat material more loose and uniform in distribution, which is more convenient for subsequent blades to cut fully and improve the crushing quality. At the same time, the thickness of the material layer is controlled, and it will not be excessively piled up and block the blades, ensuring sufficient operating space for the blades. When the feed rate of the production line returns to normal and the material accumulation in the conical feed hopper 3 decreases, the overall load decreases accordingly. The pressure of the pressure cylinder 20 is released, and it automatically resets and extends, driving the conical feed hopper 3 to reset upward. After the pressure cylinder 20 is depressurized, the piston rod of the first hydraulic cylinder 16 retracts, and the stretched reset spring 11 releases its elastic potential energy, pulling the second mounting plate 10 and the overall sliding bushing 7 to move upward. The movable cutting blade 8 moves upward synchronously, and the blade spacing gradually returns to the initial standard size. During the upward movement of the sliding bushing 7, the adjusting rod 30 and the guide block 31 slide in opposite directions along the spiral guide groove 28, driving the first worm gear 25 to rotate in the opposite direction. After being driven by the first worm wheel 26 and the transmission shaft 24, the movable cutting blade 8 gradually rotates back to its horizontal position. Simultaneously, the second hydraulic cylinder 19 automatically retracts, and the piston rod end face is flush with the inner wall of the feed hopper again, and the equipment returns to normal cutting conditions. No manual intervention is required throughout the process. It can adapt to fluctuations in the feed rate in real time, avoid over-crushing of small-flow materials, and quickly adapt to dynamic changes in the feed rate. It further simplifies the equipment control structure, reduces the probability of failure, and can quickly adapt to changes in working conditions for continuous cyclic operation. After being thoroughly pulverized by the blade assembly, the meat material continuously falls through the cutting sleeve 4 and the discharge sleeve 5, driving the main shaft 6 to rotate continuously. At the same time, the first pulley 35 at the lower end rotates synchronously, and the power is transmitted to the second pulley 41 through the transmission belt 42. The second pulley 41 drives the transmission rod 38 to rotate, and the second worm gear 43 on the transmission rod 38 rotates synchronously. Through the meshing transmission with the second worm wheel 44, the spiral feeding shaft 33 is driven to rotate. The entire feeding mechanism relies on the main drive motor 14 to provide unified power, without the need for an additional independent drive source, simplifying the overall circuit and control structure, and reducing energy consumption and failure probability. The rotating spiral feeding shaft 33 continuously pushes the material forward, and the spiral blades further stir and knead the meat, making the meat texture more uniform and delicate. Under the action of the spiral thrust, the material is continuously squeezed forward and finally squeezed out from the extrusion plate 34 at the end of the feeding pipe 32. It is divided into meat particles of uniform size by the plate and the final forming process is completed.
