[0007] In one embodiment, the fine cutting assembly includes a threaded positioning ring threadedly connected to the end of the meat grinder away from the machine base, the surface of the threaded positioning ring is fixedly connected to a positioning arc plate, the side of the threaded positioning ring away from the meat grinder is fixedly connected to a plurality of first shearing pieces, one side of the positioning arc plate is connected to a connecting round cover, the connecting round cover is sleeved on the surface of the threaded positioning ring, the surface of the connecting round cover is connected to a guide circulation sleeve, and the inner wall of the connecting round cover is rotatably connected to a rotating disk. The rotating disk is fixedly connected to the end of the meat grinder spiral. When the meat grinder spiral guides the cut meat block, the meat mincer seat and the rotating disk are driven to rotate synchronously, and the meat block is initially cut by the meat mincer seat and the meat outlet plate. When fine meat filling is needed, the connecting round cover can be sleeved on the surface of the threaded positioning ring, and is positioned and connected to the positioning arc plate by bolts. Since the side of the threaded positioning ring away from the machine base is a conical arc surface, and the first shearing piece is fixedly connected to the conical arc surface.

The annular sleeve is connected to the fixed pipe, the meat filling enters the inside of the connecting elbow through the fixed pipe and the rotating pipe, and is introduced into the meat grinder for re-mincing, so that the meat filling does not need to be manually put into the meat grinder again, forming an automatic circulation effect.

[0009] In one embodiment, one end of the first rotating shaft passes through the interior of the machine base and is fixedly connected to a first gear, and a second gear is fixedly connected to the surface of the second rotating shaft, and the second gear is meshed with the first gear. The second gear and the upper pulley are driven to rotate synchronously by the rotation of the second rotating shaft, and the second rotating shaft can also drive multiple cutting blades to follow the rotation. Under the cooperation of the second gear and the first gear, the first rotating shaft rotates relatively slowly relative to the second rotating shaft, and the first rotating shaft and the second rotating shaft rotate in opposite directions, and the first rotating shaft drives the rolling seat to follow and rotate synchronously.

[0010] In one embodiment, two pulleys are arranged on the side of the second gear away from the cutting blade, the two pulleys are respectively fixedly connected to the second rotating shaft and the surface of the meat mincer, and the surfaces of the two pulleys are sleeved with transmission belts.

The above-mentioned split-type automatic meat grinder does not require the operator to pre-cut the meat block. The rolling seat and the cutting blade can automatically cut the meat block through the combination. At the same time, under the cooperation of the second gear and the first gear, when the cutting blade cuts the meat block, the rolling seat can assist the cutting blade to squeeze and position the meat block, assist the cutting blade to cut the meat block, and automatically guide the meat block into the meat grinder, while driving the meat grinder spiral to work, thereby saving the labor intensity of the operator to pre-process the meat block. During the processing of the device, the fine cutting component is set to automatically cut the initially cut meat filling into finer pieces, so that the meat filling can be cut more delicately, reducing the user's manual operation of fine cutting of the meat filling, saving the user's labor intensity, and at the same time, it can also form an automatic circulation effect on the meat filling, so that the fine cutting component automatically cuts the meat filling multiple times, reducing the labor intensity of the operator.

One end of the second rotating shaft 312 passes through the interior of the machine base 100 and is fixedly connected to the output shaft of the motor 110. A rolling seat 313 is fixedly connected to the surface of the first rotating shaft 311. A plurality of cutting blades 314 are fixedly connected to the surface of the second rotating shaft 312. A plurality of cutting ring grooves 315 are provided on the surface of the rolling seat 313. The surfaces of the cutting blades 314 extend to the interior of adjacent cutting ring grooves 315. A tooth groove 316 is provided on the surface of the rolling seat 313. One end of the first rotating shaft 311 passes through the interior of the machine base 100 and is fixedly connected to the output shaft of the motor 110. A rolling seat 313 is fixedly connected to the surface of the second rotating shaft 312. A plurality of cutting ring grooves 315 are provided on the surface of the rolling seat 313. The surfaces of the cutting blades 314 extend to the interior of adjacent cutting ring grooves 315. A tooth groove 316 is provided on the surface of the rolling seat 313. A first gear 318 is inserted into the interior of the machine base 100 and is fixedly connected thereto. A second gear 319 is fixedly connected to the surface of the second rotating shaft 312. The second gear 319 is meshedly connected to the first gear 318. Two pulleys 3110 are arranged on the side of the second gear 319 away from the cutting blade 314. The two pulleys 3110 are respectively fixedly connected to the second rotating shaft 312 and the surface of the meat mincing spiral 220. A transmission belt 3111 is sleeved on the surface of the two pulleys 3110. A plurality of spring pieces 317 are fixedly connected to both sides of the cutting blade 314. The plurality of spring pieces 317 are distributed in a ring shape along the surface of the second rotating shaft 312. When the device is in use, a whole piece of meat can be put into the hopper 210. At this time, the driving motor 110 causes the second rotating shaft 312 to rotate accordingly, and then the second rotating shaft 312 drives the second gear 319 and the upper pulley 3110 to rotate synchronously, and the second rotating shaft 312 can also drive the multiple cutting blades 314 to rotate accordingly. Under the cooperation of the second gear 319 and the first gear 318, the first rotating shaft 311 rotates relatively slowly relative to the second rotating shaft 312. , and the first rotating shaft 311 and the second rotating shaft 312 rotate in opposite directions, the first rotating shaft 311 drives the rolling seat 313 to rotate synchronously, and at the same time the pulley 3110 drives the meat mincing spiral 220 to rotate synchronously through the transmission belt 3111, and the meat pieces are put into the hopper 210 and fall on the upper ends of the rolling seat 313 and the cutting blade 314. Driven by the first rotating shaft 311 and the second rotating shaft 312, the meat pieces are squeezed by the rolling seat 313 and the cutting blade 314 and transported to the bottom of the hopper 210; The tooth grooves 316 on the surface of the rolling seat 313 and the depressions on the surface of the cutting blade 314 assist in positioning the meat block to prevent the meat block from slipping. When the meat block falls into the groove on the surface of the cutting blade 314, it is supported and positioned. When the cutting blade 314 rotates, the groove gradually enters the cutting ring groove 315. At this time, the cutting blade 314 can cut the meat block. At the same time, the spring piece 317 contacts the surface of the rolling seat 313. Since the rotation speed of the second rotating shaft 312 is faster than that of the first rotating shaft 314, the meat block can be cut. 11. When the meat is cut and located between adjacent cutting blades 314, the spring piece 317 contacts the surface of the rolling seat 313 and deforms and accumulates elastic potential energy during the rotation. When the spring piece 317 separates from the surface of the rolling seat 313, the elastic potential energy is released, and the cut meat is pushed into the meat grinder 200. A longitudinal groove is provided on the surface of the spring piece 317. A vertical plate can be placed on the inner wall of the hopper 210 to pass through the longitudinal groove to assist the spring piece 317 in separating from the meat. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, the fine cutting assembly 320 includes a threaded positioning ring 321 threadedly connected to the end of the meat grinder 200 away from the machine base 100, a positioning arc plate 322 is fixedly connected to the surface of the threaded positioning ring 321, a plurality of first shearing pieces 323 are fixedly connected to the side of the threaded positioning ring 321 away from the meat grinder 200, a connecting round cover 324 is connected to one side of the positioning arc plate 322, the connecting round cover 324 is sleeved on the surface of the threaded positioning ring 321, a guide circulation sleeve 325 is connected to the surface of the connecting round cover 324, a rotating disk 326 is rotatably connected to the inner wall of the rotating disk 326, a guide block 327 is fixedly connected to one side of the rotating disk 326, the guide block 327 is rotatably connected to the inner wall of the threaded positioning ring 321, a plurality of second shearing pieces 328 are fixedly connected to the surface of the rotating disk 326, the rotating disk 326 is fixedly connected to the end of the meat grinder spiral 220, and a guide outlet hole 329 is provided on the surface of the connecting round cover 324; The rotating disk 326 is fixedly connected to the end of the meat mincer 220. When the meat mincer 220 guides the cut meat, the meat mincer seat 240 and the rotating disk 326 are driven to rotate synchronously. The meat mincer seat 240 and the meat outlet plate 230 are used to make a preliminary cut of the meat. When fine meat filling is needed, the connecting round cover 324 can be sleeved on the surface of the threaded positioning ring 321. At this time, it is positioned and connected to the positioning arc plate 322 by bolts. Since the side of the threaded positioning ring 321 away from the machine base 100 is a conical arc surface, and the first shearing piece 323 is fixedly connected to the conical arc surface, the meat filling passes through the meat outlet plate 230 and is moved toward the first shearing piece 323 by the guide shifting block 327; The meat filling moves through the adjacent first shearing pieces 323 toward the outside of the connecting circular cover 324. Since the width of the first shearing pieces 323 close to the rotation center of the rotating disk 326 is greater than the width of the first shearing pieces 323 away from the rotation center of the rotating disk 326, the gap between the adjacent first shearing pieces 323 is gradually reduced from the rotating disk 326 toward the connecting circular cover 324. When the meat filling passes through the adjacent first shearing pieces 323, it is gradually squeezed and overflows in the direction of the first shearing pieces 323 away from the threaded positioning ring 321. The second shearing pieces 328 and the guide The second shearing piece 328 and the guide block 327 are in contact with each other, and the second shearing piece 328 and the guide block 327 are both curved arc-shaped. At the same time, the bending directions of the second shearing piece 328 and the guide block 327 are opposite, so that the second shearing piece 328 and the guide block 327 form a shearing effect in combination, which helps to cut the meat filling more delicately, wherein the outlet hole 329 is connected with the gap between the adjacent first shearing pieces 323, and after the second shearing piece 328 cuts the overflowing meat filling, the meat filling is driven by the second shearing piece 328 and discharged through the outlet hole 329 under the action of centrifugal force and subsequent meat filling; like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig. 9 , Fig.10 As shown, the guide circulation sleeve 325 includes an annular sleeve 3251 fixedly connected to the surface of the connecting circular cover 324, one side of the annular sleeve 3251 is connected to a fixed pipe 3252, the other end of the fixed pipe 3252 is rotatably connected to a rotating pipe 3253, the other end of the rotating pipe 3253 is threadedly connected to a connecting elbow 3254, the connecting elbow 3254 is connected to the surface of the meat grinder 200, the other side of the annular sleeve 3251 is fixedly connected to a fixing frame 3255, the inner wall of the fixing frame 3255 is rotatably connected to a threaded ring 3256, the other side of the annular sleeve 3251 is provided with a discharge port 3259, the inner wall of the threaded ring 3256 is threadedly connected to a threaded shaft 3257, the surface of the threaded shaft 3257 is fixedly connected to a sealing plug 3258, and the sealing plug 3258 is located on the inner wall of the discharge port 3259; After the meat filling is squeezed out of the outlet hole 329, it is located inside the annular sleeve 3251. If more delicate meat filling is needed, the threaded ring 3256 can be manually turned to cooperate with the threaded shaft 3257 threadedly connected thereto to drive the sealing plug 3258, and the sealing plug 3258 can be moved to the outlet 3259, so that the annular sleeve 3251 is connected to the fixed tube 3252, and the meat filling enters the interior of the connecting elbow 3254 through the fixed tube 3252 and the rotating tube 3253, and is introduced into the meat grinder 200 for a second mincing operation, so that the meat filling does not need to be manually put into the meat grinder 200 again, forming an automatic circulation effect; When the meat filling reaches a fine degree, the operator can manually turn the knob of the threaded ring 3256 so that the threaded shaft 3257 drives the sealing plug 3258 to move to the inside of the fixed tube 3252. At this time, the meat filling cannot enter the fixed tube 3252. Due to the subsequent replenishment of the meat filling, the meat filling inside the annular sleeve 3251 is discharged to the outside through the discharge port 3259. At the same time, the meat filling inside the fixed tube 3252 can be turned by the knob to rotate the tube 3253, so that the rotating tube 3253 is separated from the connecting bend 3254 to take out the internal meat filling, thereby reducing the labor intensity of the operator.

[0024] Working principle: When the device is in use, a whole piece of meat is put into the hopper 210, and the driving motor 110 drives the second rotating shaft 312 to rotate accordingly, and then the second rotating shaft 312 drives the second gear 319 and the upper pulley 3110 to rotate synchronously, and the second rotating shaft 312 also drives multiple cutting blades 314 to rotate accordingly. Under the cooperation of the second gear 319 and the first gear 318, the first rotating shaft 311 rotates relatively slowly relative to the second rotating shaft 312, and the first rotating shaft 311 and the second rotating shaft 312 rotate in opposite directions. The first rotating shaft 311 drives the rolling seat 313 to rotate accordingly, and the pulley 3110 drives the meat mincing spiral 220 to rotate synchronously through the transmission belt 3111. The meat piece is put into the hopper 210 and falls on the upper end of the rolling seat 313 and the cutting blade 314. Under the drive of the first rotating shaft 311 and the second rotating shaft 312, the meat piece is squeezed by the rolling seat 313 and the cutting blade 314 to be transported to the bottom of the hopper 210; The connecting round cover 324 is sleeved on the surface of the threaded positioning ring 321 and is positioned and connected to the positioning arc plate 322 by bolts. When the mincing spiral 220 guides the cut meat block, it drives the mincing knife seat 240 and the rotating disk 326 to rotate synchronously. The mincing knife seat 240 and the meat outlet plate 230 form a preliminary cut on the meat block. When the meat filling passes through the adjacent first shearing piece 323, it is gradually squeezed. The second shearing piece 328 and the guide block 327 form a shearing effect to help cut the meat filling more delicately. The second shearing piece 328 cuts the overflowing meat filling and discharges it to the annular sleeve 325 through the outlet hole 329. 1, the operator manually turns the knob threaded ring 3256 to make the threaded shaft 3257 drive the sealing plug 3258 to move to the discharge port 3259, at which time the annular sleeve 3251 is connected to the fixed tube 3252, and the meat filling enters the connecting elbow 3254 through the fixed tube 3252 and the rotating tube 3253, and is introduced into the meat grinder 200 to be minced again. When the meat filling reaches a good and delicate degree, the operator manually turns the knob threaded ring 3256 to make the threaded shaft 3257 drive the sealing plug 3258 to move to the inside of the fixed tube 3252, and the meat filling inside the annular sleeve 3251 is discharged to the outside through the discharge port 3259.

[0025] The technical features of the above-described embodiments may be arbitrarily combined.
