[0025] S4. When the flow rate value detected by the multiple flow rate sensors below is less than the preset flow rate value, the movable conical tube moves toward the middle shaft end, the axial distance between the movable conical tube and the linkage shaft decreases, the auger drives the movable conical tube to vibrate up and down to increase the amplitude, and the drying gas discharged from the exhaust hole increases the force of clearing the meat inside the minced meat chamber.

[0026] The application of the meat mincing device in the production of meat sausages.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention sets a shell assembly, a meat grinding assembly and an adjustment assembly and other components to cooperate with each other. The device is simple to operate, stable and efficient, meets the needs of fast and efficient meat grinding processing of meat blocks, has stronger adaptability and higher stability, realizes batch production needs, and has better controllability and higher safety, reduces labor intensity, improves meat grinding efficiency, and ensures the quality of minced meat.

[0029] 2. The present invention sets an intermediate shaft and a movable cone tube and other components to cooperate with each other. When the meat is fed between the intermediate shaft and the movable cone tube, the rotation of the movable cone tube improves the uniformity and dispersion of the meat inside the arc bucket, and multiple exhaust holes discharge dry gas, which not only realizes the wind-driven dredging and dehumidification of the meat, but also can perform wind-driven cleaning on the meat mincing chamber and the inside of the arc bucket to avoid the meat from sticking and reducing the feeding efficiency. The auger continuously squeezes and collides with the movable cone tube and drives the movable cone tube to vibrate up and down, further improving the feeding and dredging of the meat.

[0030] 3. The present invention cooperates with other components such as flow rate sensors and movable cone tubes. When the meat is blocked between the middle shaft and the movable cone tube, the flow rate values ​​detected by the multiple flow rate sensors above are reduced, and the gap between the movable cone tube and the middle shaft is adjusted accordingly, thereby ensuring that the meat is fed quickly and efficiently, and can also drive the movable cone tube to vibrate back and forth to further improve the feeding effect.

[0031] 4. The present invention sets the coordination between the intermediate shaft and the annular cutter and other components. When a large piece of meat is blocked between the intermediate shaft and the movable conical tube, the movable conical tube moves toward the end of the intermediate shaft and cooperates with the rotation and cutting of the annular cutter to decompose the large piece of meat, thereby ensuring that the subsequent pieces of meat can be unloaded smoothly.

[0032] 5. The present invention sets the meat grinder chamber and the auger to cooperate with each other. When the meat blocks in the meat grinder chamber are blocked, the movable conical tube continuously moves back and forth, and the axial positions of the movable conical tube and the intermediate shaft continuously change, and the extrusion pressure of the movable conical tube and the auger continuously changes, thereby improving the unblocking and cleanliness of the movable conical tube on the meat blocks in the meat grinder chamber.

[0048] The adjusting component 3 includes an intermediate shaft 301, which is located at the central axis position inside the arc bucket 107. Both sides of the intermediate shaft 301 are fixedly connected to the inner wall of the arc bucket 107, so the position of the intermediate shaft 301 does not change, thereby realizing the zoned discharge of the meat chunks inside the arc bucket 107, avoiding the accumulation of the meat chunks inside the arc bucket 107 inside the feeding tube 201 and affecting the subsequent transmission and cutting effects. Both sides of the intermediate shaft 301 are symmetrically and movably connected with movable conical tubes 302 at an angle below. The length of the movable conical tubes 302 is less than the length of the arc bucket 107. The movable conical tubes 302 can move and swing in any direction inside the arc bucket 107, further improving the discharge efficiency and discharge effect of the meat chunks inside the arc bucket 107, and avoiding blockage and the like that may affect the subsequent discharge of the meat chunks.

[0049] If the height of the middle shaft 301 is greater than the height of the movable conical tubes 302 on both sides, the movable conical tubes 302 will continuously rotate on both sides and realize the sliding efficiency of the meat pieces above the middle shaft 301 to both sides, ensuring that the meat pieces can evenly and quickly fall down to the inside of the feeding tube 201 for mincing. The diameter of the movable conical tube 302 gradually increases from the middle to both sides.

An annular cutter 322 is provided in the middle of the outer surface of the movable conical tube 302. The diameter of the annular cutter 322 is the same as the maximum diameter on both sides of the movable conical tube 302. When the meat pieces inside the arc bucket 107 are too large and affect the subsequent feeding of the meat pieces, the movable conical tube 302 moves toward the end close to the middle shaft 301 and cooperates with the rotation of the annular cutter 322 to quickly cut the meat pieces, so as to avoid blocking the arc bucket 107 and affecting the subsequent feeding.

[0050] A circulation cavity 303 is provided inside the movable conical tube 302, and gas circulates inside the circulation cavity 303.

Then, the gas inside the circulation cavity 303 is discharged along the plurality of exhaust holes 304, which can not only improve the feeding efficiency and cleaning effect of the meat pieces inside the arc bucket 107, but also monitor the blockage of the meat pieces inside the arc bucket 107 in real time and adjust the feeding efficiency accordingly. A flow rate sensor 305 is provided inside the exhaust hole 304, and the flow rate sensor 305 is used to detect the flow rate value inside the exhaust hole 304.

[0051] Two side grooves 306 are symmetrically arranged on both sides of the interior of the arc-shaped bucket 107, and bottom grooves 307 are arranged at the inner bottoms of the side grooves 306, and the side grooves 306 and the bottom grooves 307 are symmetrically distributed.

The other end of the ventilation pipe 324 passes through the material transfer pipe 201 and the box body 101 and is connected to the output end of the air pump 323. The air pump 323 is started and the drying gas is pumped into the ventilation pipe 324. The gas inside the ventilation pipe 324 enters the center hole 309 inside the connecting pipe 308 through the hose 311, and finally enters the circulation cavity 303 along the center hole 309. The drying gas inside the circulation cavity 303 is finally discharged along a plurality of exhaust holes 304, further improving the dredging, cleaning and dehumidification effect of the meat pieces inside the arc bucket 107.

[0052] The other end of the bearing seat 310 is evenly provided with a plurality of first elastic rods 312. The setting of the first elastic rods 312 realizes the inclination of the bearing seat 310. The other end of the first elastic rods 312 is provided with a first magnetic ring 313.

The setting of the first spring 314 improves the elastic reset effect of the first magnetic ring 313. The first electromagnetic block 315 The other end is fixedly connected to the inner wall of the side groove 306. When the positive current passed through the first electromagnetic block 315 increases and the magnetic repulsion force on the first magnetic ring 313 increases, the first magnetic ring 313 stretches the first spring 314 to move away from the end of the first electromagnetic block 315. The hose 311 is located between the multiple first elastic rods 312, and the outer surface of the ventilation pipe 324 matches the inner wall of the first magnetic ring 313. Even if the bearing seat 310 moves inside the side groove 306, the hose 311 can still pass gas into the center hole 309, thereby ensuring the discharge efficiency and discharge stability of the gas inside the exhaust hole 304.

A plurality of second elastic rods 318 are evenly provided at the other end of the transmission motor 317, and a second magnetic ring 319 is provided at the other end of the second elastic rod 318. The second elastic rod 318 elastically connects the second magnetic ring 319 and the transmission motor 317, so as to realize the transmission motor 317 in the side groove 306. The second magnetic ring 319 is movably connected internally, and the outer surface of the second magnetic ring 319 matches the inner wall of the bottom groove 307. A second spring 320 is provided on one side of the second magnetic ring 319, and a second electromagnetic block 321 is provided on the other end of the second spring 320. The setting of the second spring 320 further improves the elastic reset performance of the second magnetic ring 319. The second electromagnetic block 321 is fixedly connected to the inner wall of the side groove 306. When the positive current passed through the second electromagnetic block 321 increases, the magnetic repulsion force applied by the second electromagnetic block 321 to the second magnetic ring 319 increases, and the second magnetic ring 319 stretches the second spring 320 and moves away from the end of the second electromagnetic block 321, thereby driving the movable cone tube 302 to be movably connected inside the arc bucket 107.

[0054] When the meat chunks enter the arc bucket 107 along the inclined bucket 104 and are discharged, if the amount of meat chunks is too much, they will accumulate in the middle of the arc bucket 107, which will easily cause blockage in the arc bucket 107 and reduce the feeding efficiency of the meat chunks, and ultimately affect the subsequent feeding of the meat chunks; at the same time, when the size of the meat chunks inside the arc bucket 107 is too large, it will get stuck inside the arc bucket 107, and it will not be able to continue to enter the feeding pipe 201 for subsequent transmission. If the larger meat chunks inside the arc bucket 107 are taken out manually, the operation will be difficult and the safety factor will be low, which may easily lead to major personal safety accidents; and the meat chunks will adhere to the inner wall of the device when being discharged, which will not only reduce the accuracy and cleanliness of the transmission, but also cause pollution to the subsequent feeding and transmission of the meat chunks.

[0055] In order to solve the above problems, the meat grinder is used in practice. Figure 4 After the left and right directions are determined, the box 101 is moved to a suitable position, the controller 103 controls the driving motor 208 to start and the output end drives the driving wheel 209 to rotate, the driving wheel 209 drives the driven wheel 211 to rotate through the conveyor belt 210, the driven wheel 211 drives the linkage shaft 202 to rotate through the coupling 213, the linkage shaft 202 drives the auger 203 to rotate inside the meat-grinding chamber 212, and the linkage shaft 202 synchronously drives the multiple cutting knives 204 to rotate, pouring the meat pieces into the inclined bucket 104, and the meat pieces pass through the arc bucket 107 and enter the meat-grinding chamber 212 inside the feeding tube 201. 12, the auger 203 drives the meat block to be continuously squeezed and conveyed forward in the meat grinding chamber 212 as the linkage shaft 202 continuously rotates, and when the meat block reaches the end of the protective shell 205 in the meat grinding chamber 212, the intermediate shaft 301 drives the multiple cutting knives 204 to continuously rotate, and the cutting knives 204 cut and crush the meat block in the meat grinding chamber 212 to form meat paste, and the meat paste is squeezed and discharged from the multiple sieve holes 207 in the sieve plate 206 under the continuous squeezing action of the subsequent meat blocks, thereby forming meat paste of the required size, and finally completing the meat grinding process of the meat block.

[0056] When the meat pieces move downward along the inclined bucket 104 to the inside of the arc bucket 107, due to the uneven distribution of the sizes of the meat pieces themselves, the meat pieces will be randomly piled up inside the arc bucket 107 and divided into sections by the intermediate shaft 301 and the movable cone tubes 302 on both sides. When the size of the meat pieces is smaller than the size between the movable cone tube 302 and the intermediate shaft 301 or between the movable cone tube 302 and the inner wall of the arc bucket 107, the meat pieces will fall downward to the inside of the meat-grinding chamber 212 inside the feeding tube 201 for subsequent extrusion and transmission, and the controller 103 controls the first electromagnetic block 315 and the second electromagnetic block 321 to be in the power-off state. The movable cone tube 302 is in the state, and the transmission motor 317 is started and drives the movable cone tube 302 to rotate through the transmission shaft 316. The other end of the movable cone tube 302 drives the connecting tube 308 to rotate inside the bearing seat 310. The two movable cone tubes 302 rotate in opposite directions and both rotate along the intermediate shaft 301 toward the front and rear side wall ends of the arc bucket 107. The meat pieces falling between the intermediate shaft 301 and the movable cone tube 302 will slide to the front and rear sides under the rotation of the movable cone tube 302, thereby improving the unblocking of the meat pieces and avoiding the accumulation of the meat pieces in the middle of the arc bucket 107 and affecting the subsequent feeding efficiency of the meat pieces.

[0057] At the same time, the controller 103 controls the air pump 323 to start and apply suction force to the drying box, so that the drying gas enters the ventilation pipe 324, and enters the center hole 309 along the ventilation pipe 324 through the hose 311, and the drying gas inside the center hole 309 enters the circulation chamber 303, and the drying gas inside the circulation chamber 303 is finally discharged along the multiple exhaust holes 304. The flow rate value detected by the flow rate sensor 305 reaches the set flow rate preset value. The drying gas exerts a gas effect on the meat pieces inside the arc bucket 107, which not only improves the fluidity of the meat pieces, avoids their accumulation inside the arc bucket 107 and affects the feeding efficiency, but also uses the drying gas to exert a drying and cleaning effect on the internal structure of the arc bucket 107 and the feeding pipe 201, further improving the transmission and unblocking properties of the meat pieces.

[0058] When the intermediate shaft 301 drives the auger 203 to rotate continuously, the auger 203 reaches the bottom of the movable cone tube 302 and applies a thrust to the movable cone tube 302, so that the movable cone tube 302 stretches the first elastic rods 312 and the second elastic rods 318 on both sides to move upward, and the movable cone tube 302 drives the top meat block to move upward. When the auger 203 is separated from the movable cone tube 302, the movable cone tube 302 is driven downward to return to its original position under the action of the gravity of the movable cone tube 302 and the meat block, and cooperates with the auger 203 to move upward. Due to its spiral structure, the contact position between the movable conical tube 302 and the auger 203 is different, which drives the movable conical tube 302 to vibrate back and forth in a wave-like manner inside the arc bucket 107. At the same time, combined with the shape and size of the movable conical tube 302, which is narrow in the center and wide on both sides, the meat pieces accumulated on the left and right sides of the arc bucket 107 are continuously gathered to the middle position and fed downward, further improving the vibration feeding effect of the meat pieces inside the arc bucket 107, avoiding the blockage of the meat pieces inside the arc bucket 107 and reducing the unblockability of the arc bucket 107.

[0059] When the meat pieces accumulate above the movable cone tube 302 on one side, the movable cone tube 302 keeps rotating and the flow rate values ​​detected by the multiple flow rate sensors 305 located above decrease, and the controller 103 controls the positive current passed into the first electromagnetic block 315 and the second electromagnetic block 321 to increase, so that the magnetic repulsion forces exerted by the first electromagnetic block 315 and the second electromagnetic block 321 on the first magnetic ring 313 and the second magnetic ring 319 respectively increase, and the first magnetic ring 313 and the second magnetic ring 319 respectively stretch the first elastic rod 312 and the second elastic rod 318 to move away from the first electromagnetic block 315 and the second electromagnetic block 321. The ring 319 drives the middle movable cone tube 302 to move away from the middle shaft 301, and the gap between the movable cone tube 302 and the middle shaft 301 increases. The meat pieces can rotate and vibrate up and down in the movable cone tube 302, and fall downward between the middle shaft 301 and the movable cone tube 302 under the driving effect of the drying gas discharged from the multiple exhaust holes 304. The flow rate values ​​detected by the multiple flow rate sensors 305 located above continue to increase and reach the set flow rate preset value, further improving the feeding efficiency and feeding unblocking of the meat pieces, and effectively avoiding the accumulation of meat pieces between the middle shaft 301 and the movable cone tube 302 and affecting the efficiency.

[0060] When the time reaches the set first time preset value, the flow rate values ​​detected by the multiple flow rate sensors 305 above are still less than the set flow rate preset value. At this time, it means that the blockage between the intermediate shaft 301 and the movable cone tube 302 is too large, and the feeding of the meat block cannot be achieved by simply increasing the gap between the intermediate shaft 301 and the movable cone tube 302. Then the controller 103 controls the positive current passed into the first electromagnetic block 315 and the second electromagnetic block 321 to increase intermittently. Then the magnetic repulsion force applied by the first electromagnetic block 315 and the second electromagnetic block 321 to the first magnetic ring 313 and the second magnetic ring 319 changes intermittently, and the first magnetic ring 313 and the second magnetic ring 319 move intermittently in the bottom groove 307 respectively. When the second electromagnetic block 321 is powered off and the first magnetic ring 313 moves away from the end of the first electromagnetic block 315, the first magnetic ring 313 drives the movable cone tube 302 to the right side away from the second electromagnetic block 315 through the first elastic rod 312, the bearing seat 310 and the connecting pipe 308. The first electromagnetic block 315 moves, and the right side of the movable cone tube 302 tilts and moves. Then, the first electromagnetic block 315 is powered off and the second electromagnetic block 321 is powered on. The second magnetic ring 319 drives the left side of the movable cone tube 302 to move away from the second electromagnetic block 321 through the second elastic rod 318, the transmission motor 317 and the transmission shaft 316, and the left side of the movable cone tube 302 tilts and moves. Then, the above process is repeated continuously, and the movable cone tube 302 continuously tilts and swings back and forth inside the arc bucket 107. In combination with the structure of the movable cone tube 302 that is narrow in the middle and wide on both sides, the meat pieces between the intermediate shaft 301 and the movable cone tube 302 are continuously squeezed in the front-to-back direction. In combination with the up and down vibration of the movable cone tube 302 and the drying gas discharged from the exhaust hole 304, the unblockability of the meat pieces falling downward from the intermediate shaft 301 and the movable cone tube 302 to the minced meat chamber 212 inside the feeding pipe 201 is further improved, so as to ensure that the meat pieces inside the arc bucket 107 are stably and efficiently discharged.

[0061] When the time reaches the set second time preset value, and the second time preset value is greater than the first time preset value, the flow rate value detected by the multiple flow rate sensors 305 above is still less than the set flow rate preset value, it means that the volume of the meat block between the intermediate shaft 301 and the movable cone tube 302 is too large and the meat block needs to be divided. At this time, the controller 103 controls the first electromagnetic block 315 and the second electromagnetic block 321 to pass reverse current and reach the maximum value. The magnetic attraction force applied by the first electromagnetic block 315 and the second electromagnetic block 321 to the first magnetic ring 313 and the second magnetic ring 319 reaches the maximum value. The first magnetic ring 313 and the second magnetic ring 319 squeeze the first spring 314 and the second spring 320 to move to the maximum value close to the first electromagnetic block 315 and the second electromagnetic block 321. The two movable cone tubes 302 move to the maximum value close to the intermediate shaft 301. The movable cone tube 302 cooperates with the intermediate shaft 301 to squeeze the meat block. The meat pieces are squeezed and cut by the movable cone tube 302 and the intermediate shaft 301, thereby quickly separating the larger pieces of meat and further improving the feeding efficiency of the subsequent pieces of meat. After the cutting of the meat pieces is completed, the controller 103 controls the first electromagnetic block 315 and the second electromagnetic block 321 to be powered off, and the first magnetic ring 313 and the second magnetic ring 319 are driven to move in the opposite direction and return to their original positions under the elastic force of the first spring 314 and the second spring 320. At this time, the flow rate value detected by the flow rate sensor 305 increases continuously to the initial value, and the above process is repeated to feed the subsequent pieces of meat.

[0062] As the movable conical tube 302 and the auger 203 continue to rotate, the meat pieces in the meat-grinding chamber 212 inside the feeding tube 201 are continuously transferred backwards. At the same time, when the meat pieces are accumulated between the meat-grinding chamber 212 and the arc-shaped bucket 107, the amount of meat pieces inside the meat-grinding chamber 212 continues to increase, and the meat pieces block the multiple exhaust holes 304 located below the movable conical tube 302. The flow rate values ​​detected by the multiple flow rate sensors 305 located below decrease, and the controller 103 controls the first electromagnetic block 315 and the second electromagnetic block 321 to pass reverse current and continuously increase it, and the magnetic attraction force exerted by the first electromagnetic block 315 and the second electromagnetic block 321 on the first magnetic ring 313 and the second magnetic ring 319 increases, and the first magnetic ring 313 and the second magnetic ring 319 squeeze the first spring 314 and the second spring 320 to approach the first electromagnetic The block 315 and the second electromagnetic block 321 end move, and the two movable conical tubes 302 move toward the middle shaft 301 end, and the distance between the movable conical tube 302 and the middle shaft 301 is reduced. Since the height of the movable conical tube 302 remains unchanged, and the linkage shaft 202 drives the auger 203 to rotate in a circle inside the minced meat chamber 212, the distance between the movable conical tube 302 and the axis of the linkage shaft 202 is reduced. When the auger 203 rotates, the extrusion pressure on the movable conical tube 302 increases, and the extrusion pressure of the movable conical tube 302 on the meat blocks inside the minced meat chamber 212 and accumulated between the arc buckets 107 increases. When the auger 203 rotates, the movable conical tube 302 is driven to increase the amplitude of the up and down vibration, thereby further improving the vibration dredging effect on the meat blocks blocked in the minced meat chamber 212, thereby avoiding long-term blockage of the meat blocks and reducing the subsequent meat mincing effect.

[0063] After the flow rate value detected by the flow rate sensor 305 returns to the initial value, the controller 103 controls the first electromagnetic block 315 and the second electromagnetic block 321 to cut off the power. Then, under the elastic force of the first spring 314 and the second spring 320, the first magnetic ring 313 and the second magnetic ring 319 are driven to move in the opposite direction and return to their original positions. The above process is repeated continuously to feed and mince the subsequent meat blocks.

[0064] The device is simple to operate, stable and efficient, meets the needs of fast and efficient meat grinding processing of meat blocks, has stronger adaptability, higher stability, meets the needs of mass production, and has better controllability and higher safety, reduces labor intensity, improves meat grinding efficiency, and ensures the quality of minced meat; at the same time, when the meat blocks are fed between the intermediate shaft 301 and the movable cone tube 302, the rotation of the movable cone tube 302 improves the uniformity and dispersion of the meat blocks inside the arc bucket 107, and the multiple exhaust holes 304 discharge dry gas, which not only realizes the wind dredging and dehumidification of the meat blocks, but also can perform wind cleaning on the meat grinding chamber 212 and the inside of the arc bucket 107, avoids the adhesion of the meat blocks and reduces the feeding efficiency, and the auger 203 continuously squeezes and collides with the movable cone tube 302 and drives the movable cone tube 302 to vibrate up and down, further improving the feeding dredging of the meat blocks; and when the meat blocks are blocked between the intermediate shaft 301 and the movable cone tube 302 When the meat is blocked, the flow rate values ​​detected by the multiple flow rate sensors 305 above are reduced, and the gap between the movable conical tube 302 and the intermediate shaft 301 is adjusted accordingly, so as to ensure that the meat is fed quickly and efficiently, and can also drive the movable conical tube 302 to vibrate back and forth to further improve the feeding effect; but when a large piece of meat is blocked between the intermediate shaft 301 and the movable conical tube 302, the movable conical tube 302 moves toward the end close to the intermediate shaft 301 and cooperates with the rotation and cutting of the annular cutter 322 to decompose the large piece of meat, so as to ensure that the subsequent meat can be fed smoothly; and when the meat inside the minced meat chamber 212 is blocked, the movable conical tube 302 moves back and forth continuously, and the axial position of the movable conical tube 302 and the intermediate shaft 301 changes continuously, then the extrusion pressure of the movable conical tube 302 and the auger 203 changes continuously, thereby improving the unblocking and cleanliness of the movable conical tube 302 on the meat inside the minced meat chamber 212.

[0065] The meat mincing method of the meat mincing device as described above comprises the following steps:

[0066] S1. The meat pieces are moved downward along the arc bucket 107 to the inside of the meat grinding chamber 212 for extrusion and transmission, the movable conical tube 302 rotates inside the arc bucket 107 and cooperates with the intermediate shaft 301 to disperse the meat pieces, the exhaust hole 304 discharges the drying gas to the outside, the flow rate value detected by the flow rate sensor 305 reaches the set flow rate preset value, the auger 203 and the movable conical tube 302 are continuously squeezed and collided and drive the movable conical tube 302 to continuously tilt and vibrate up and down.

[0067] S2. When the flow rate values ​​detected by the multiple flow rate sensors 305 above are less than the set flow rate preset value, the movable cone tube 302 moves away from the middle shaft 301, and the gap between the movable cone tube 302 and the middle shaft 301 increases. When the time reaches the first time preset value, the flow rate values ​​detected by the multiple flow rate sensors 305 above are still less than the set flow rate preset value, and the movable cone tube 302 tilts and swings back and forth inside the arc bucket 107.

[0068] S3. When the time reaches the second time preset value, the second time preset value is greater than the first time preset value, and the flow rate values ​​detected by the multiple flow rate sensors 305 above are still less than the set flow rate preset value, the movable cone tubes 302 on both sides move toward the end close to the middle shaft 301, and the movable cone tubes 302 rotate in the opposite direction and cooperate with the middle shaft 301 to cut the meat.

[0069] S4. When the flow rate value detected by the multiple flow rate sensors 305 below is less than the preset flow rate value, the movable conical tube 302 moves toward the end close to the intermediate shaft 301, the axial distance between the movable conical tube 302 and the linkage shaft 202 decreases, the auger 203 drives the movable conical tube 302 to increase its up and down vibration amplitude, and the drying gas discharged from the exhaust hole 304 increases the clearing force of the meat pieces inside the minced meat chamber 212.

[0070] The meat mincing method has high meat mincing efficiency, good meat mincing effect, strong flowability and stable material feeding.
