[0002] Rice grains consist of the husk, bran, germ, and endosperm. The purpose of rice processing is to separate the endosperm from the other parts with minimal breakage, producing rice with good eating quality. After rice production, the rice needs to be packaged and sealed for transportation and sale.

[0003] The packaging bags at the bottom of existing rice packaging machines are usually manually placed on the rice hopper outlet. After the bags are filled with rice, they are vacuum-sealed. During the bag placement process, manual bag filling and opening are required, while mechanical equipment completes a series of mechanized operations such as filling and vacuuming. Therefore, if the packaging bags can be opened automatically, it can replace manual labor and further improve the level of automation in rice packaging.

Detailed Implementation

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] Reference Figures 1 to 6 This invention discloses a multi-station intelligent packaging machine for rice processing, comprising: a turntable 1, which is rotatably mounted on a base 7 via a drive structure, and a plurality of rice filling mechanisms 2 are provided at equal intervals around the turntable 1, with packaging bags placed inside the rice filling mechanisms 2.

[0057] The rice loading mechanism 2 is connected to a negative pressure adsorption mechanism, and the inner wall of the rice loading mechanism 2 is provided with an air hole matrix 204.

[0058] After the packaging bag is placed in the rice filling mechanism 2, the negative pressure adsorption mechanism adsorbs the outer wall of the packaging bag through the air hole matrix 204, making it open.

[0059] It also includes a rice outlet 10 and a capping mechanism 17, located above the turntable 1. Any rice loading mechanism 2 moves to the direct below the rice outlet 10 or the capping mechanism 17 after the turntable 1 rotates.

[0060] Rice outlet 10 fills rice into an open packaging bag.

[0061] The capping mechanism 17 is driven by a lifting mechanism. The capping mechanism 17 is combined with any opposite rice loading mechanism 2. The capping mechanism 17 and the rice loading mechanism 2 together form a vacuum adsorption cavity 1705. The vacuum adsorption cavity 1705 is connected to the negative pressure adsorption mechanism through the capping mechanism 17, the rice loading mechanism 2 and the negative pressure adsorption mechanism in sequence.

[0062] The sealing mechanism 17 includes a sealing part, which seals the opening of the packaging bag after the rice is vacuumed.

[0063] In use, multiple rice filling mechanisms 2 are mounted on the turntable 1. By directly inserting the packaging bag into the rice filling mechanism 2 with the opening facing upward, the negative pressure adsorption mechanism will adsorb the side wall of the packaging bag through the air hole matrix 204 opened on the inner wall of the rice filling mechanism 2, making it adhere to the inner wall of the rice filling mechanism 2, with the packaging bag in an open shape. Then, the drive structure makes the turntable 1 rotate, moving the rice filling mechanism 2 carrying the open packaging bag to directly below the rice discharge port 10. Rice is quantitatively discharged into the packaging bag from the rice discharge port 10, making the packaging bag full of rice. Then, the turntable 1 rotates, and the previous packaging bag containing rice moves to below the sealing mechanism 17, and the other rice filling mechanism 2 carrying the open packaging bag moves to below the rice discharge port 10, thus realizing continuous bagging. After the sealing mechanism 17 is aligned with one of the rice filling mechanisms 2, it is lowered by the lifting mechanism, and the sealing mechanism 17 and the corresponding rice filling mechanism 2 are combined to form a vacuum adsorption chamber 1705. At this time, the vacuum adsorption chamber 1705 is connected to the negative pressure adsorption mechanism through the sealing mechanism 17, the rice filling mechanism 2, and the rice packaging bag is located in the vacuum adsorption chamber 1705. The air in the packaging bag is extracted, and at the same time, the sealing part closes the opening of the packaging bag, completing the rice packaging process. After the sealing mechanism 17 is separated from the corresponding rice filling mechanism 2, the rice packaging bag can be taken out.

[0064] As an optional implementation, the meter loading mechanism 2 includes: The box 201 has an air intake channel 202 inside, and an air hole matrix 204 is formed on the inner wall of the box 201, and the air hole matrix 204 is connected to the air intake channel 202.

[0065] The bottom of the air intake channel 202 is connected to an air outlet 205, and the top of the air intake channel 202 is connected to multiple connecting nozzles 203.

[0066] The air outlet 205 is connected to the negative pressure adsorption mechanism.

[0067] After the connecting nozzle 203 is inserted into the sealing mechanism 17, it communicates with the vacuum adsorption cavity 1705 formed by the sealing mechanism 17 and the box 201.

[0068] In use, the packaging bag is placed inside the box 201. The negative pressure adsorption mechanism acts on the suction channel 202 through the air outlet 205 and adsorbs the side wall of the packaging bag through the air hole matrix 204, fixing it and leaving it open. When the filling mechanism rotates to the sealing position, the sealing mechanism 17 descends and assembles, and its connecting air nozzle 203 is inserted into the sealing mechanism 17, so that the vacuum adsorption cavity 1705 formed by the two and the box 201 is connected to the suction channel 202. At this time, the same negative pressure adsorption mechanism can be reused to evacuate the packaging bag through this passage. This design realizes the efficient reuse of the negative pressure system in the two core processes of "fixing and opening the bag" and "evacuating the bag", and simplifies the air path structure.

[0069] As an optional implementation, the connecting nozzle 203 includes a tube 2031, which is fixed on the housing 201, and the bottom end of the tube 2031 is connected to the air intake channel 202.

[0070] Two second limiting rings 2032 are coaxially fixed inside the tube body 2031. A magnetic piston 2033 is slidably arranged between the two second limiting rings 2032. The magnetic piston 2033 is magnetically engaged with the capping mechanism 17.

[0071] A first connecting vent 2034 is provided between the two second limiting rings 2032.

[0072] The magnetic piston 2033 is used to block the first connecting vent 2034.

[0073] After the tube body 2031 is inserted into the capping mechanism 17, the magnetic piston 2033 moves in conjunction with the capping mechanism 17, so that the air intake channel 202 is connected to the vacuum adsorption chamber 1705 through the tube body 2031 and the first connecting air hole 2034.

[0074] When the sealing mechanism 17 is not engaged with the housing 201, the magnetic piston 2033 inside the tube 2031 connecting the air nozzle 203 naturally blocks the first connecting air hole 2034. When the sealing mechanism 17 descends and engages with the housing 201, the magnetic force it generates attracts the magnetic piston 2033 to move between the two second limiting rings 2032 inside the tube 2031, thereby opening the first connecting air hole 2034. This allows the suction channel 202 on the housing 201 to connect with the vacuum adsorption cavity 1705 formed by the sealing mechanism 17 and the housing 201 through the tube 2031 and the first connecting air hole 2034. This structure utilizes magnetic force to achieve automatic and reliable opening and closing of the air path, ensuring that the negative pressure adsorption mechanism can be reused for both the fixing and opening of the packaging bag and the vacuuming process.

[0075] As an optional implementation, the capping mechanism 17 includes: The cover 1701 is fixed to the movable end of the lifting mechanism.

[0076] The bottom of the cap 1701 is provided with an air nozzle channel 1704 that is compatible with the tube body 2031, and the air nozzle channel 1704 corresponds one-to-one with the tube body 2031.

[0077] A magnet 1703 is fixedly attached to the top of the air nozzle channel 1704, and the magnet 1703 is magnetically engaged with the magnetic piston 2033.

[0078] The air nozzle channel 1704 has a second connecting air hole 1706 on its side wall, which matches and connects with the first connecting air hole 2034.

[0079] The cover 1701 and the box 201 together form a vacuum adsorption cavity 1705.

[0080] After the tube body 2031 is inserted into the air nozzle channel 1704, the magnet 1703 and the magnetic piston 2033 are magnetically engaged, and the first connecting air hole 2034 and the second connecting air hole 1706 are connected accordingly. At this time, the vacuum adsorption chamber 1705 is connected to the air intake channel 202.

[0081] The sealing part is located inside the vacuum adsorption chamber 1705.

[0082] When the lifting mechanism drives the capping mechanism 17 to descend, the air nozzle channel 1704 at the bottom of the cap 1701 precisely aligns with and inserts into the tube 2031 on the metering mechanism 2. At this time, the magnet 1703 fixed at the top of the air nozzle channel 1704 magnetically engages with the magnetic piston 2033 inside the tube 2031, attracting the magnetic piston 2033 to move upward within the tube 2031, thereby releasing its blockage of the first connecting air hole 2034. As the magnetic piston 2033 moves, the first connecting air hole 2034 on the tube 2031 corresponds to and connects with the second connecting air hole 1706 on the side wall of the air nozzle channel 1704. Thus, the vacuum adsorption cavity 1705 formed by the cap 1701 and the box 201 is connected to the suction channel 202 inside the box 201 through this connecting air path: second connecting air hole 1706 → first connecting air hole 2034. This allows the negative pressure adsorption mechanism to perform vacuuming on the packaging bag inside the vacuum adsorption chamber 1705. After completion, the sealing part located inside the vacuum adsorption chamber 1705 immediately seals the bag opening. This design achieves automatic and precise connection of the vacuum path through magnetic coupling, ensuring the reliability of the seal.

[0083] As an alternative implementation, the sealing part includes a guide rail 1709, which is formed on the inner wall of the cover 1701 inside the vacuum adsorption chamber 1705.

[0084] Two symmetrically arranged clamps 1710 slide within the guide rail 1709. One end of a flexible metal 1708 is fixed to the clamp 1710. The middle part of the flexible metal 1708 slides with the cover 1701 through a 90-degree bent slide. The other end of the flexible metal 1708 is used to contact the top of the housing 201.

[0085] A spring is provided inside the guide rail 1709. The spring is located between two clamps 1710, and the end of the spring is fixed to the corresponding clamp 1710.

[0086] The chuck 1710 and the flexible metal 1708 are integrated into one structure, and the chuck 1710 and the flexible metal 1708 are heat exchanged.

[0087] It also includes a heating strip 1707, which is in contact with and heat-exchanges with the sidewall of the flexible metal 1708, and the heating strip 1707 is fixed inside the cover 1701.

[0088] The heating strip 1707 is electrically connected to the power supply 1702, which is fixed to the cover 1701.

[0089] When the cap 1701 is assembled with the box 201, the bottom end of the box 201 contacts the flexible metal 1708. As the cap 1701 and the box 201 approach each other, the flexible metal 1708 is pushed, causing one end of the flexible metal 1708 carrying the clamp 1710 to slide along the guide rail 1709 and compress the spring. The opening of the packaging bag closes as the two clamps 1710 approach each other. As the cap 1701 and the box 201 are assembled, the packaging bag is also sealed.

[0090] After the vacuum adsorption chamber 1705 evacuates the packaging bag, the power supply 1702 supplies power to the heating strip 1707.

[0091] The heating strip 1707 transfers heat to the flexible metal 1708 in contact with it, and through heat transfer, the clamp 1710 heats and presses the sealing area of ​​the packaging bag to complete the sealing.

[0092] As an optional implementation, the driving structure includes: Rotate the ventilation shaft 4, which is fixed on the base 7, and rotate the ventilation shaft 4 in a coaxial manner with the turntable 1.

[0093] A driven gear 5 is coaxially fixed at the bottom of the turntable 1, and the driven gear 5 is driven by a drive unit.

[0094] As an optional implementation, the drive unit includes a first servo motor 9, with its fixed end fixed to the base 7. The output shaft of the first servo motor 9 is coaxially fixed with a drive gear 11, which meshes with the driven gear 5.

[0095] When the equipment is running, the first servo motor 9 starts, and its output shaft drives the drive gear 11 to rotate. The drive gear 11 meshes with the driven gear 5 fixed to the bottom of the turntable 1, thereby transmitting power to the driven gear 5 and driving the turntable 1 to rotate precisely around the rotating ventilation shaft 4 fixed on the base 7. This design not only achieves stable drive and multi-station switching of the turntable 1, but its core advantage lies in the fact that the structure of the rotating ventilation shaft 4 provides coaxial rotational support for the turntable 1 and also provides a central channel for the air passage connection required by the multiple meter loading mechanisms 2 above it, making the overall structure more compact and reliable.

[0096] As an optional implementation, the negative pressure adsorption mechanism includes: The first airway 3 is located inside turntable 1.

[0097] The second airway 8 is located inside the rotating ventilation shaft 4.

[0098] The first airway 3 is connected to the second airway 8.

[0099] The first air passage 3 is connected to the bottom of the rice loading mechanism 2.

[0100] The first airway 3 is connected to the air outlet 205.

[0101] The second air passage 8 is connected to a vacuum exhaust pump 6, which is fixed on the base 7.

[0102] The vacuum exhaust pump 6 starts, establishing negative pressure through the second air passage 8 inside the rotating ventilation shaft 4 and the first air passage 3 inside the turntable 1. This negative pressure is sequentially transmitted to the air outlet 205 at the bottom of each rice filling mechanism 2, and finally acts on the packaging bag through the air passage inside the box. The core advantage of this design is that, by setting a fixed air passage connected inside the rotating parts, it cleverly solves the technical problem of needing to stably and continuously supply negative pressure to each station during the continuous rotation of the turntable, ensuring the continuity and reliability of processes such as packaging bag adsorption and vacuuming.

[0103] As an optional implementation, the lifting mechanism includes a platform 15, which is fixed to the cover mechanism 17 and the cover 1701. The platform 15 is driven by a lifting part.

[0104] As an optional implementation, the lifting unit includes a threaded rod 14, which is threadedly engaged with the base 15. The output shaft of the second servo motor 13 is coaxially fixed to the threaded rod 14. The fixed end of the second servo motor 13 is fixed to the base 7. The base 15 is vertically slidably engaged with a slide rod 12. The bottom end of the slide rod 12 is fixed to the base 7. A first limiting ring 16 is fixed to the slide rod 12. The first limiting ring 16 is engaged with the top of the base 15 for limiting.

[0105] When vacuuming and sealing operations are required, the second servo motor 13 starts, driving the threaded rod 14 on its output shaft to rotate. The rotational motion of the motor is converted into precise vertical lifting and lowering motion of the support 15 along the stationary slide rod 12 via the support 15, which is threaded into the support 14. The entire capping mechanism 17, including the cap 1701, fixed to the support 15, rises and falls synchronously. When the support 15 rises to the top, it engages with the first limiting ring 16 fixed to the slide rod 12, thus stopping accurately. This structure achieves smooth and precise lifting and lowering control of the capping mechanism through the servo motor and threaded rod pair, ensuring reliable assembly with the metering mechanism below.
