The outer cylinder 2 is rotatably connected, one end of the second fixing frame 13 is connected to the conveying assembly 3, and the other end of the second fixing frame 13 is movably connected to the outer cylinder 2. A rice discharge port 24 is provided at the bottom of the outer cylinder 2. A pressure rod 10 is installed on the side of the outer cylinder 2 away from the vacuum machine upper cover 4. The pressure rod 10 is intermittently contacted and connected with the vacuum machine upper cover 4. The inner sleeve 8 is rotatably installed on the inner wall of the outer cylinder 2. A plurality of sieve holes 83 are provided on the inner wall of the inner sleeve 8. A The inner sleeve 8 has a cavity 84, a broken rice discharge port 85 is provided on the outer wall of the inner sleeve 8, a through hole 86 is provided on the inner wall and the outer wall of the inner sleeve 8, the cavity 84 is located at the position of the through hole 86 and is sealed and connected to the inner wall and the outer wall of the inner sleeve 8, and rotating plates 87 are rotatably installed on both sides of the through hole 86, and electromagnets 25 are provided on both sides of the rice discharge port 24, and the rotating plate 87 is made of a magnetophilic metal, and a third spring 89 is provided between the rotating plate 87 and the outer wall of the inner sleeve 8, and the first A mounting frame 16 is fixedly mounted on the support frame 11 and the second support frame 15, the vacuum machine lower cover 5 is fixedly connected to the mounting frame 16, a telescopic member 9 is mounted on the mounting frame 16, the output end of the telescopic member 9 is connected to the extrusion plate 6, a conveying assembly 3 is mounted on one end of the outer cylinder 2, a driving assembly 7 is mounted on the other end of the outer cylinder 2, the conveying assembly 3 is used to transport rice to the center of the inner sleeve 8, and the driving assembly 7 is used to drive the inner sleeve 8 to rotate intermittently and drive the outer cylinder 2 to swing intermittently.

[0031] In this embodiment, the top of the mounting frame 16 is an inclined surface, and a second spring 41 is provided between the upper cover 4 of the vacuum machine and the lower cover 5 of the vacuum machine. When vacuum packaging of rice is performed, the conveying assembly 3 is firstly started to convey the rice to the inside of the inner sleeve 8, and the rice packaging bag is placed below the rice discharge port 24, and the inner sleeve 8 is driven to rotate by the driving assembly 7; when the rice discharge port 24 coincides with the through-hole 86, the electromagnet 25 is energized, and the rotating plate 87 is opened for unloading through the attraction of the electromagnet 25 and the rotating plate 87, and the rotating plate 87 is rotated. As the movable plate 87 is rotated to open, the rotating plates 87 on both sides extend into the packaging bag, and the packaging bag is stretched open as it rotates. While unloading, the extrusion plates 6 are driven by the telescopic member 9 to squeeze the two sides of the packaging bag, so that the shape of the packaging bag can be fixed. In the prior art, the vacuum shape is fixed by an open limit box, but it is difficult to take out the packaging bag after the vacuum is completed. In this embodiment, the vacuum shape is limited by the extrusion plates 6 movable on both sides. After the rice is filled, the electromagnet 25 is powered off, and the rotating plates 87 on both sides are opened again. The outer cylinder 2 and the inner sleeve 8 are driven to rotate in the opposite direction by the driving assembly 7, and the outer cylinder 2 rotates toward the upper cover 4 of the vacuum machine. During the rotation, the outer cylinder 2 drives the sealing end of the packaging bag to bend relative to the lower half of the packaging bag until the sealing end extends between the upper cover 4 and the lower cover 5 of the vacuum machine. At this time, during the reverse rotation of the outer cylinder 2 and the inner sleeve 8, the broken rice discharge port 85 partially overlaps with the rice discharge port 24, and the broken rice is discharged at this time. Through the oblique setting of the upper cover 4 of the vacuum machine and the mounting frame 16 The top inclined surface is used to guide the material. During the continuous rotation of the outer cylinder 2, the pressure rod 10 acts on the upper cover 4 of the vacuum machine, squeezes the upper cover 4 of the vacuum machine, so that the upper cover 4 of the vacuum machine and the lower cover 5 of the vacuum machine are closed. At this time, the vacuuming operation and the sealing operation are performed. After the operation is completed, the outer cylinder 2 and the inner sleeve 8 rotate in the same direction, and the inner sleeve 8 always rotates in one direction. The outer cylinder 2 swings intermittently. After the outer cylinder 2 rotates in the opposite direction, the pressure rod 10 moves away from the upper cover 4 of the vacuum machine. At this time, the upper cover 4 of the vacuum machine rotates to the initial position, and the vacuum packaging operation can be completed.

[0032] See also Figure 4 , Figure 5 , Fig. 9 In one embodiment, a disturbance plate 81 is fixedly installed on the inner wall of the inner sleeve 8 in the circumferential direction. The disturbance plate 81 is provided with a plurality of through holes 82 , and the aperture of the through holes 82 is larger than the aperture of the sieve hole 83 .

[0033] In this embodiment, by providing a disturbance plate 81, the inner sleeve 8 can drive the disturbance plate 81 to rotate inside the inner sleeve 8 while rotating, so as to achieve the stirring of the internal rice and prevent the rice from agglomerating inside and blocking the rice discharge port 24 and the through-hole 86. Secondly, by providing a through hole 82 with a larger aperture than the sieve hole 83, the rice particles can pass through the through hole 82. The sieve hole 83 is used to screen broken rice.

[0034] See also Figure 1 , Figure 2 , Figure 5 In one embodiment, the conveying assembly 3 includes a conveying cylinder 31, a first motor 32, a feed port 33, a rotating shaft 34, and a spiral blade 35. The conveying cylinder 31 and the first motor 32 are fixedly connected to the first fixed frame 12, the first motor 32 is connected to the rotating shaft 34, the rotating shaft 34 is provided with a spiral blade 35, and a feed port 33 is opened at the top of the conveying cylinder 31.

[0035] In this embodiment, the spiral blades 35 can be used to transport the rice, and the rice can be transported to the inner sleeve 8 for packaging.

[0036] See also Figure 1 , Figure 2 In one embodiment, the driving assembly 7 includes a second motor 71, a half gear 72, a toothless gear 73, a full gear 74, and a fixed gear 75. The second motor 71 is fixedly mounted on the first support frame 11, and the second motor 71 is connected to the half gear 72 and the toothless gear 73. A full gear 74 is fixedly mounted on the other end of the inner sleeve 8, and a plurality of fixed teeth 75 are fixedly mounted on one end of the outer cylinder 2. The fixed teeth 75 are meshed and connected with the half gear 72, and the toothless gear 73 is meshed and connected with the full gear 74. The outer cylinder 2 is connected to the second fixed frame 13 through a torsion spring 21.

[0037] In this embodiment, the intermittent rotation of the inner sleeve 8 and the intermittent swinging of the outer cylinder 2 are realized through a group of drives. The intermittent rotation is to stop for a short time when the through-port 86 rotates to the bottom, and keep rotating for the rest of the time. The intermittent swinging is to swing back and forth at a small angle, and stop for a short time when the rice discharge port 24 rotates to the bottom.

[0038] In this embodiment, by connecting the half gear 72 and the toothless gear 73 to the second motor 71, the toothless gear 73 is disengaged from the full gear 74, and the half gear 72 is also disengaged from the fixed tooth 75. The through-hole 86 rotates to the bottom, and the rice discharge port 24 is also located at the bottom, that is, the rice discharge port 24 coincides with the through-hole 86. When the half gear 72 is just disengaged from the fixed tooth 75, the outer cylinder 2 is rotated from the position of the vacuum machine cover 4 to just below under the action of the torsion spring 21, and then remains stationary for a period of time.

[0039] The driving assembly 7 may also use two separate motors to drive the inner sleeve 8 and the outer sleeve 2 separately.

[0040] See also Fig. 9 In one embodiment, a flexible block 88 is installed on one side of the rotating plate 87 close to the third spring 89 .

[0041] In this embodiment, by providing a flexible block 88, when the rotating plate 87 is rotated to open, the flexible block 88 fits exactly into the interior of the packaging bag, which can increase the friction between the flexible block 88 and the interior of the packaging bag, thereby preventing the packaging bag from detaching from the rotating plate 87, making the rice feeding process smoother.

[0042] See also Figures 1 to 4 In one embodiment, it also includes a hollow frame 17, a hollow tube 18, a fixed rod 19, a sliding frame 20, and a storage table 22. The hollow frame 17 is slidably connected to the sliding frame 20, and a first spring 23 is installed between the hollow frame 17 and the sliding frame 20. The storage table 22 is fixedly installed at one end of the sliding frame 20 away from the hollow frame 17. Hollow tubes 18 are arranged on both sides of the hollow frame 17. One end of the hollow tube 18 is connected to the inner cavity of the hollow frame 17, and the other end of the hollow tube 18 is slidably and sealingly connected to the fixed rod 19. The end of the fixed rod 19 away from the hollow tube 18 is connected to the extrusion plate 6, and the hollow frame 17 and the hollow tube 18 are filled with hydraulic oil.

[0043] In this embodiment, hydraulic oil is filled between the hollow frame 17 and the sliding frame 20 and in the hollow tube 18. During the rice discharging process, due to the gravity of the rice, the storage table 22 and the sliding frame 20 sink, and the extrusion plates 6 on both sides move toward each other to squeeze the two sides of the rice packaging bag, thereby plasticizing the rice packaging bag.

[0044] See also Figures 2 to 4 In one embodiment, a telescopic member 9 is fixedly mounted on the extrusion plate 6 close to the upper cover 4 of the vacuum machine, and a conveying assembly 1 is arranged below the extrusion plate 6 .

[0045] In this embodiment, after the vacuum operation is completed, the packaged rice still remains on the storage table 22. At this time, the telescopic member 9 drives one extrusion plate 6 to move toward the direction close to the upper cover 4 of the vacuum machine, and the other extrusion plate 6 naturally moves toward the direction close to the upper cover 4 of the vacuum machine, thereby tilting the packaged rice. Under the continuous push of the telescopic member 9, the rice packaging bag moves to the conveying component 1.

[0046] See also Figure 1 , Figure 3 In one embodiment, a collection frame 14 is fixedly mounted on the mounting frame 16 .

[0047] In this embodiment, the broken rice can be collected by the collecting frame 14 .
