Description

Technical Field

[0001] The invention belongs to the technical field of food packaging machines, and in particular relates to a rice packaging machine. Background Art

[0002] A rice packing machine is a device for packing rice, and is widely used in the field of catering.

[0003] Patent application number CN202311103002.9 discloses a rice baler comprising a frame, a rice trough and several weighing modules mounted on the frame, a bracket connected to the weighing modules, a rice dispensing trough connected to the bracket, the rice dispensing troughs located below the rice trough, two opening and closing buckets rotatably connected to the lower ends of the rice dispensing troughs, an opening and closing mechanism connected between the two opening and closing buckets; a transverse movement mechanism mounted on the transverse movement mechanism, a clamping mechanism for clamping rice bags, a sealing mechanism for sealing the rice bags mounted on the frame, the sealing mechanism corresponding to one side of the transverse movement mechanism, and a bag dispensing mechanism disposed at the bottom of the frame. The present invention provides a rice baler capable of accurately filling rice bags and automatically sealing rice bags.

[0004] However, the above rice packing machine requires manual operation to put rice into the bag, and cannot realize fully automatic rice packing. Summary of the Invention

[0005] In order to solve the above problems existing in the prior art, the object of the present invention is to provide a rice packaging machine that does not require manual operation.

[0006] The technical solution adopted in the present invention is:

[0007] A rice packaging machine comprises a frame, on which are mounted, from top to bottom, a bulk material bin, a rice weighing unit, a rice temporary storage bin, a rice bag sealing unit, a rice bag fixing and sucking mechanism, a vibration unit and a rice bag conveyor belt; the frame is also mounted with a rice bag clamping unit, a rice bag flipping and sucking mechanism and a rice bag storage bin; when the rice bag flipping and sucking mechanism is flipped to a horizontal position, it faces directly below the rice bag storage bin; when the rice bag flipping and sucking mechanism is flipped to a vertical position, it faces directly opposite the rice bag fixing and sucking mechanism; the rice bag clamping unit is located between the rice bag fixing and sucking mechanism and the rice bag flipping and sucking mechanism.

[0008] The cooked rice is poured into the bulk hopper, which then breaks it up. The broken rice falls at a uniform rate into the rice weighing unit, where it is weighed. Once the rice in the rice weighing unit reaches the set value, the rice is pushed into the temporary rice storage hopper. The rice bag flipping and closure mechanism then pulls the bottom rice bag into the storage hopper, flipping it to a position aligned with the fixed bag closure mechanism. The bag clamping unit clamps both ends of the bag, while the fixed bag closure mechanism clamps the other side of the bag opening, opening it. The temporary rice storage hopper then opens, allowing the rice to fall into the bag. The lower part of the bag is supported by a vibration unit, which vibrates the bag to ensure that the rice falls into the bag. Once all the rice in the temporary rice storage hopper has fallen into the bag, the bag sealing unit clamps the bag opening and heats it to seal it. After sealing, the bag falls onto the bag conveyor, where the packaged rice is automatically discharged.

[0009] The bulk silo of the present invention breaks up the rice, the rice weighing unit accurately weighs it, and the rice temporary storage bin temporarily stores the rice in preparation for packaging. A rice bag flipping and closure mechanism automatically draws in and transfers the rice bag to a predetermined position. With the rice bag clamping unit clamping both ends of the rice bag, the rice bag flipping and closure mechanism and the rice bag fixing and closure mechanism open the rice bag. Rice from the temporary rice storage bin falls into the rice bag, which is vibrated by a vibration unit to ensure a fixed and reliable amount of rice is loaded into the bag. After packaging, the rice bag sealing unit automatically seals the bag. The entire process of breaking up, weighing, temporary storage, bag retrieval, bag clamping, bag opening, packaging, bag sealing, vibration, and delivery is automated, eliminating the need for manual operation. The present invention accurately weighs the rice and breaks and shakes it during rice transportation, ensuring accuracy and reliability during rice packaging. The rice bag flipping and closure mechanism automatically removes the rice bag from the rice bag storage bin and flips it to a predetermined position, eliminating the need for manual bag placement.

[0010] As a preferred embodiment of the present invention, the bulk material bin includes a bulk material hopper fixed to the top of a frame. Several bulk material rollers rotate within the hopper. These rollers are equipped with bulk material teeth and are connected to adjacent rollers via a gear transmission. A bulk material drive mechanism is also mounted on the hopper, with the output end of the drive mechanism connected to one of the rollers. The bulk material drive mechanism comprises a motor and a reducer. After the motor is started, it drives the reducer, which in turn drives one of the bulk material rollers to rotate. Adjacent rollers are connected via a gear transmission. Consequently, when adjacent rollers rotate in opposite directions, the rice clumps are fully broken up, allowing the rice to fall into the rice weighing unit at a uniform rate.

[0011] As a preferred embodiment of the present invention, the rice weighing unit includes a rice weighing device installed on a frame, a rice tray is installed on the rice weighing device, a rice pushing cylinder is installed on the rice tray, a displacement weighing bucket is fixed on the piston rod of the rice pushing cylinder, and a rice receiving plate is also fixed on the displacement weighing bucket; when the piston rod of the rice pushing cylinder is retracted, the upper opening of the displacement weighing bucket is aligned with the lower opening of the bulk hopper, and the lower side of the displacement weighing bucket contacts the rice tray; when the piston rod of the rice pushing cylinder is extended, the rice receiving plate is aligned with the lower opening of the bulk hopper, and the lower opening of the displacement weighing bucket is aligned with the upper opening of the rice temporary storage bin.

[0012] As the rice in the bulk silo falls into the rice weighing unit, the rice tray seals the lower opening of the mobile weighing hopper, and the rice scale performs real-time weighing. When the rice weight reaches the set value, the rice pushing cylinder pushes the mobile weighing hopper into the temporary rice storage bin, allowing all the weighed rice to fall into the temporary storage bin. At this point, the rice receiving plate seals the lower opening of the bulk silo to prevent further rice from falling. The rice weighing unit automatically weighs and transfers the rice.

[0013] As a preferred embodiment of the present invention, the rice temporary storage bin includes a temporary storage lifting cylinder installed on a frame, the piston rod of the temporary storage lifting cylinder is connected to a temporary rice storage bucket, both sides of the lower opening of the temporary rice storage bucket are rotatably connected to an opening and closing plate, an opening and closing cylinder is installed on the temporary rice storage bucket, the piston rod of the opening and closing cylinder is fixed with a driving rod, both ends of the driving rod are rotatably connected to an opening and closing connecting rod, a rocker arm is fixed to the opening and closing plate, and the other end of the rocker arm is rotatably connected to the opening and closing connecting rod through an opening and closing shaft.

[0014] When the rice pushing cylinder pushes the shifted weighing bucket to above the rice temporary storage bucket, the temporary storage lifting cylinder lifts the rice temporary storage bucket to ensure that the rice temporary storage bucket can accurately catch the rice. After the rice bag flipping suction mechanism and the rice bag fixing suction mechanism open the rice bag, the rice temporary storage bucket is lowered. The opening and closing cylinder drives the two opening and closing connecting rods through the driving rod, and the opening and closing connecting rods drive the opening and closing plates to open through the opening and closing rotating shaft. After the two opening and closing plates are opened, the rice falls into the rice bag. The rice temporary storage bin of the present invention can temporarily store the weighed rice and drop the rice into the rice bag at the right time, ensuring the continuity of the entire rice packaging process.

[0015] As a preferred embodiment of the present invention, a plurality of scattering rods rotate within the temporary rice storage bucket. The scattering rods are provided with scattering teeth, and adjacent scattering rods are connected by a gear transmission. The temporary rice storage bucket is also equipped with a scattering drive mechanism, and the output end of the scattering drive mechanism is connected to one of the scattering rods. The scattering drive mechanism comprises a motor and a reducer. When the motor is started, it drives the reducer. The reducer drives one of the scattering rods to rotate, and adjacent scattering rods are connected by a gear transmission. Thus, when adjacent scattering rods rotate in opposite directions, the rice in the temporary rice storage bucket is fully scattering, allowing the rice to fall completely into the rice bag.

[0016] As a preferred embodiment of the present invention, the rice bag sealing unit includes a rice bag sealing forward cylinder and a rice bag sealing reverse cylinder installed on a frame and arranged in opposite directions. The piston rod of the rice bag sealing forward cylinder is connected to a rice bag forward sealing heating block, and the piston rod of the rice bag sealing reverse cylinder is connected to a rice bag reverse guide rod. The other end of the rice bag reverse guide rod is connected to the rice bag reverse sealing heating block. The rice bag sealing forward cylinder and the rice bag sealing reverse cylinder are both located on a side of the rice bag forward sealing heating block away from the rice bag reverse sealing heating block.

[0017] The forward and reverse seal cylinders operate simultaneously. The forward cylinder extends the forward seal heating block, while the reverse cylinder pushes the reverse guide rod, which in turn extends the reverse seal heating block. The forward and reverse seal heating blocks clamp and heat the bag opening from opposite directions, achieving automatic sealing.

[0018] The rice bag sealing forward cylinder and the rice bag sealing reverse cylinder are both located on the side of the rice bag forward sealing heating block away from the rice bag reverse sealing heating block, so that the space between the rice bag forward sealing heating block and the rice bag reverse sealing heating block is not blocked, ensuring that the rice falls smoothly into the rice bag from the space.

[0019] A rice bag forward guide plate is fixed to the piston rod of the rice bag forward sealing cylinder. A rice bag reverse guide rod extends through the rice bag forward guide plate. The rice bag forward sealing heater block is mounted on the rice bag forward guide plate. A rice bag reverse guide plate is fixed to the piston rod of the rice bag reverse sealing cylinder. A rice bag guide rod is fixed to the machine frame. The rice bag reverse guide rod extends through the rice bag reverse guide plate. The rice bag reverse guide rod is also fixed to the machine frame. A rice bag reverse guide sleeve is also mounted on the machine frame. The rice bag reverse guide rod extends through the rice bag reverse guide sleeve. Both the rice bag forward and reverse sealing heater blocks are reliably guided during movement, ensuring a secure rice bag seal.

[0020] As a preferred embodiment of the present invention, the rice bag clamping unit includes a rice bag clamping lifting cylinder mounted on a frame. The piston rod of the rice bag clamping lifting cylinder is connected to a rice bag clamping bracket. A rice bag clamping adjustment cylinder is mounted at each end of the rice bag clamping bracket. The piston rods of the rice bag clamping adjustment cylinders are mounted to rice bag clamping claw cylinders. The rice bag clamping lifting cylinder drives the rice bag clamping bracket to a predetermined height. Depending on the size of the rice bag, the rice bag clamping adjustment cylinder moves the rice bag clamping claw cylinders to a predetermined position, adjusting the spacing between the two rice bag clamping claw cylinders to suit the size of the rice bag. The rice bag clamping claw cylinders clamp the two ends of the rice bag, facilitating the opening of the rice bag to be opened by the rice bag flipping and fixing mechanisms.

[0021] As a preferred embodiment of the present invention, the rice bag securing and closing mechanism includes a rice bag securing and closing telescopic cylinder mounted on a frame. The piston rod of the rice bag securing and closing telescopic cylinder is connected to a rice bag securing and closing frame. The rice bag securing and closing frame is equipped with a plurality of rice bag securing suction cups for securing one side of the rice bag. The rice bag securing suction cups are located on the side of the rice bag gripper cylinder away from the rice bag flipping and closing frame. The rice bag securing and closing telescopic cylinder pushes the rice bag securing and closing frame out, and the plurality of rice bag securing suction cups on the rice bag securing and closing frame securely securely secure one side of the rice bag.

[0022] As a preferred embodiment of the present invention, the rice bag turning and closing mechanism includes a rice bag turning cylinder installed on a frame, the frame is rotatably connected to a rice bag turning frame, a rice bag turning connecting rod is fixed to the rice bag turning frame, the piston rod of the rice bag turning cylinder is rotatably connected to the other end of the rice bag turning connecting rod, a rice bag first-level extending cylinder is installed on the rice bag turning frame, the piston rod of the rice bag first-level extending cylinder is connected to the rice bag second-level extending cylinder, the piston rod of the rice bag second-level extending cylinder is connected to the rice bag turning and closing frame, a number of rice bag turning suction cups for closing the other side of the rice bag are installed on the rice bag turning and closing frame, when the rice bag turning and closing frame is turned horizontally, it is opposite to the bottom of the rice bag storage bin, and when the rice bag turning and closing frame is turned vertically, it is opposite to the rice bag fixed suction mechanism.

[0023] The piston rods of the first and second rice bag extension cylinders extend sequentially, allowing the rice bag flipping suction cups on the rice bag flipping and closing frame to close the rice bag on the bottom layer of the rice bag storage compartment. The rice bag flipping cylinder drives the rice bag flipping frame to flip 90 degrees, allowing the rice bag to be flipped to a position directly opposite the rice bag securing and closing mechanism. At this point, the rice bag clamping unit clamps both ends of the rice bag, and the rice bag securing and closing mechanism closes the other side of the rice bag, thereby opening the rice bag. The rice bag flipping and closing mechanism of the present invention automatically draws in the rice bag and flips it to the packaging position, eliminating the need for manual operation.

[0024] As a preferred embodiment of the present invention, the vibration unit includes a vibrating lifting cylinder mounted on a frame, the piston rod of the vibrating lifting cylinder being connected to a vibrating mounting plate, the vibrating plate being rotatably connected to the vibrating plate. The vibrating plate is located below the rice bag clamping unit, and the vibrating cylinder is mounted on the vibrating mounting plate, the piston rod of the vibrating cylinder being rotatably connected to the vibrating plate. The vibrating lifting cylinder can drive the vibrating mounting plate to rise and fall, thereby enabling the vibrating plate to accurately support the bottom of the rice bag. After the vibrating cylinder is activated, the piston rod of the vibrating cylinder pulls the vibrating plate to tilt slightly up and down, thereby achieving the vibrating effect of the vibrating plate on the rice bag, thereby evenly vibrating the rice within the rice bag.

[0025] The beneficial effects of the present invention are:

[0026] The bulk silo of the present invention breaks up the rice, the rice weighing unit accurately weighs it, and the rice temporary storage bin temporarily stores the rice in preparation for packaging. A rice bag flipping and closure mechanism automatically draws in and transfers the rice bag to a predetermined position. With the rice bag clamping unit clamping both ends of the rice bag, the rice bag flipping and closure mechanism and the rice bag fixing and closure mechanism open the rice bag. Rice from the temporary rice storage bin falls into the rice bag, which is vibrated by a vibration unit to ensure a fixed and reliable amount of rice is loaded into the bag. After packaging, the rice bag sealing unit automatically seals the bag. The entire process of breaking up, weighing, temporary storage, bag retrieval, bag clamping, bag opening, packaging, bag sealing, vibration, and delivery is automated, eliminating the need for manual operation. The present invention accurately weighs the rice and breaks and shakes it during rice transportation, ensuring accuracy and reliability during rice packaging. The rice bag flipping and closure mechanism automatically removes the rice bag from the rice bag storage bin and flips it to a predetermined position, eliminating the need for manual bag placement.

DETAILED DESCRIPTION

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0049] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0050] like Figures 1 to 20As shown, the rice packaging machine of this embodiment includes a frame 1, on which are mounted, from top to bottom, a bulk material bin 2, a rice weighing unit 3, a rice temporary storage bin 4, a rice bag sealing unit 5, a rice bag fixing and suction mechanism 6, a vibration unit 7, and a rice bag conveyor belt 11. The frame 1 is also mounted with a rice bag clamping unit 8, a rice bag flipping and suction mechanism 9, and a rice bag storage bin 12. When the rice bag flipping and suction mechanism 9 is flipped to a horizontal position, it faces the bottom of the rice bag storage bin 12. When the rice bag flipping and suction mechanism 9 is flipped to a vertical position, it faces the rice bag fixing and suction mechanism 6. The rice bag clamping unit 8 is located between the rice bag fixing and suction mechanism 6 and the rice bag flipping and suction mechanism 9.

[0051] The bulk material bin 2, the rice weighing unit 3, the rice temporary storage bin 4, the rice bag sealing unit 5, the rice bag fixing and suction mechanism 6, the vibration unit 7, the rice bag conveyor belt 11, the rice bag clamping unit 8, the rice bag turning and suction mechanism 9 and the rice bag storage bin 12 serve as a group of rice packaging units. The present invention has two groups of rice packaging units arranged side by side.

[0052] The cooked rice is poured into the bulk hopper 2, which then breaks it up. The broken rice falls at a uniform rate into the rice weighing unit 3, where it is weighed. Once the rice in the rice weighing unit 3 reaches the set value, the rice is pushed into the rice temporary storage hopper 4. At this point, the rice bag flipping and closure mechanism 9 pulls the rice bag in from the bottom of the rice bag storage hopper 12, flipping it to a position aligned with the rice bag fixing mechanism 6. The rice bag clamping unit 8 clamps both ends of the rice bag, while the rice bag fixing mechanism 6 clamps the other side of the rice bag opening, opening the bag. The temporary storage hopper now opens, allowing the rice to fall into the rice bag. The lower portion of the rice bag is supported by the vibration unit 7, which vibrates the rice bag to ensure that it falls into the bag. Once all the rice in the temporary rice storage hopper 42 has fallen into the rice bag, the rice bag sealing unit 5 clamps and heats the opening of the rice bag to seal it. After sealing, the rice bag falls onto the rice bag conveyor belt 11 and the packaged rice is automatically output.

[0053] The bulk silo 2 of the present invention breaks up the rice, the rice weighing unit 3 accurately weighs it, and the rice temporary storage silo 4 temporarily stores the rice in preparation for packaging. The rice bag flipping and suction mechanism 9 can automatically suck up the rice bag and transfer it to a certain position. When the rice bag clamping unit 8 clamps both ends of the rice bag, the rice bag opening is opened by the rice bag flipping and suction mechanism 9 and the rice bag fixing and suction mechanism 6. The rice in the rice temporary storage silo 4 falls into the rice bag and is vibrated by the vibration unit 7 to ensure that the rice is quantitatively and reliably loaded into the rice bag. After packaging, the rice bag sealing unit 5 automatically seals the bag. The entire process of breaking up, weighing, temporarily storing, taking out the bag, clamping the bag, opening the bag, packaging, sealing, vibrating, and outputting is automated, requiring no manual operation. The present invention can accurately weigh the rice, break it up and vibrate it during the rice transportation process, and ensure accuracy and reliability during the rice packaging process. The meal bag turning and sucking mechanism 9 of the present invention can automatically take out the meal bag in the meal bag storage bin 12 and turn the meal bag to a certain position, thereby avoiding the operation of manually placing the bag.

[0054] Specifically, the bulk material bin 2 includes a bulk material hopper 21 fixed to the top of the frame 1. Several bulk material rollers 22 rotate within the bulk material hopper 21. Each of the bulk material rollers 22 is equipped with bulk material teeth, and adjacent bulk material rollers 22 are connected via a gear transmission. A bulk material drive mechanism 23 is also mounted on the bulk material hopper 21, and the output end of the bulk material drive mechanism 23 is connected to one of the bulk material rollers 22. The bulk material drive mechanism 23 comprises a motor and a reducer. After the motor is started, the motor drives the reducer, which in turn drives one of the bulk material rollers 22 to rotate. Adjacent bulk material rollers 22 are connected via a gear transmission. As a result, when adjacent bulk material rollers 22 rotate in opposite directions, the rice clumps are fully broken up, allowing the rice to fall into the rice weighing unit 3 at a uniform speed.

[0055] The rice weighing unit 3 includes a rice weighing device 31 mounted on the frame 1, a rice tray 32 mounted on the rice weighing device 31, a rice pushing cylinder 33 mounted on the rice tray 32, a displacement weighing bucket 34 fixed on the piston rod of the rice pushing cylinder 33, and a rice receiving plate 35 fixed on the displacement weighing bucket 34; when the piston rod of the rice pushing cylinder 33 is retracted, the upper opening of the displacement weighing bucket 34 is aligned with the lower opening of the bulk hopper 21, and the lower side of the displacement weighing bucket 34 contacts the rice tray 32; when the piston rod of the rice pushing cylinder 33 is extended, the rice receiving plate 35 is aligned with the lower opening of the bulk hopper 21, and the lower opening of the displacement weighing bucket 34 is aligned with the upper opening of the rice temporary storage bin 4.

[0056] As the rice in the bulk silo 2 falls into the rice weighing unit 3, the rice tray 32 seals the lower opening of the movable weighing hopper, and the rice weighing unit 31 performs real-time weighing. When the rice weight reaches the set value, the rice pushing cylinder 33 pushes the shifting weighing hopper 34 into the rice temporary storage silo 4, allowing all the weighed rice to fall into the temporary storage silo 4. At this point, the rice receiving plate 35 seals the lower opening of the bulk silo 2 to prevent further rice from falling. The rice weighing unit 3 enables automatic weighing and transfer of rice.

[0057] The rice temporary storage bin 4 includes a temporary storage lifting cylinder 41 installed on the frame 1, a temporary storage lifting cylinder 41 is connected to a temporary rice storage bucket 42 on the piston rod, and both sides of the lower opening of the temporary rice storage bucket 42 are rotatably connected to an opening and closing plate 43, an opening and closing cylinder 44 is installed on the temporary rice storage bucket 42, a driving rod 45 is fixed to the piston rod of the opening and closing cylinder 44, and both ends of the driving rod 45 are rotatably connected to an opening and closing connecting rod 46, a swing rod 47 is fixed to the opening and closing plate 43, and the other end of the swing rod 47 is rotatably connected to the opening and closing connecting rod 46 through an opening and closing rotating shaft.

[0058] When the rice pushing cylinder 33 pushes the shifting weighing bucket 34 to above the rice temporary storage bucket 42, the temporary storage lifting cylinder 41 lifts the rice temporary storage bucket 42 to ensure that the rice temporary storage bucket 42 can accurately catch the rice. After the rice bag flipping suction mechanism 9 and the rice bag fixing suction mechanism 6 open the rice bag, the rice temporary storage bucket 42 is lowered. The opening and closing cylinder 44 drives the two opening and closing connecting rods 46 to move through the driving rod 45, and the opening and closing connecting rods 46 drive the opening and closing plates 43 to open through the opening and closing rotating shaft. After the two opening and closing plates 43 are opened, the rice falls into the rice bag. The rice temporary storage bin 4 of the present invention can temporarily store the weighed rice and drop the rice into the rice bag at the right time to ensure the continuity of the entire rice packaging process.

[0059] Several scattering rods 48 rotate within the temporary rice storage hopper 42. Each scattering rod 48 is equipped with scattering teeth, and adjacent scattering rods 48 are connected by a gear transmission. A scattering drive mechanism 49 is also mounted on the temporary rice storage hopper 42, and the output end of the scattering drive mechanism 49 is connected to one of the scattering rods 48. The scattering drive mechanism 49 comprises a motor and a reducer. The motor starts, driving the reducer. The reducer drives one of the scattering rods 48 to rotate, and adjacent scattering rods 48 are connected by a gear transmission. Thus, when adjacent scattering rods 48 rotate in opposite directions, the rice in the temporary rice storage hopper 42 is fully scattering, allowing the rice to fall completely into the rice bag.

[0060] The rice bag sealing unit 5 includes a rice bag sealing forward cylinder 51 and a rice bag sealing reverse cylinder 52 installed on the frame 1 and arranged in opposite directions. The piston rod of the rice bag sealing forward cylinder 51 is connected to the rice bag forward sealing heating block 53, and the piston rod of the rice bag sealing reverse cylinder 52 is connected to the rice bag reverse guide rod 54. The other end of the rice bag reverse guide rod 54 is connected to the rice bag reverse sealing heating block 55. The rice bag sealing forward cylinder 51 and the rice bag sealing reverse cylinder 52 are both located on the side of the rice bag forward sealing heating block 53 away from the rice bag reverse sealing heating block 55.

[0061] The forward and reverse seal cylinders 51 and 52 operate simultaneously. The forward cylinder 51 extends the forward seal heating block 53, while the reverse cylinder 52 extends the reverse guide rod 54. The reverse guide rod 54 then extends the reverse seal heating block 55. The forward and reverse seal heating blocks 53 and 55 clamp and heat the opening of the rice bag from opposite directions, achieving automatic sealing.

[0062] The rice bag sealing forward cylinder 51 and the rice bag sealing reverse cylinder 52 are both located on the side of the rice bag forward sealing heating block 53 away from the rice bag reverse sealing heating block 55, so that the space between the rice bag forward sealing heating block 53 and the rice bag reverse sealing heating block 55 is not blocked, ensuring that the rice falls smoothly into the rice bag from this space.

[0063] A rice bag forward guide plate 56 is fixed to the piston rod of the rice bag sealing forward cylinder 51. A rice bag reverse guide rod 54 passes through this guide plate 56. The rice bag forward heating block 53 is mounted on this guide plate 56. A rice bag reverse guide plate 57 is fixed to the piston rod of the rice bag reverse cylinder 52. A rice bag guide rod 58 is fixed to the frame 1. This guide rod 58 passes through this guide plate 57. The rice bag reverse guide rod 54 is fixed to this guide plate 57. A rice bag guide sleeve 59 is also fixed to the frame 1. The rice bag reverse guide rod 54 passes through this sleeve 59. Both the rice bag forward heating block 53 and the rice bag reverse heating block 55 are reliably guided during movement, ensuring a secure rice bag seal.

[0064] The rice bag clamping unit 8 comprises a rice bag clamping lifting cylinder 81 mounted on the frame 1. A rice bag clamping bracket 82 is connected to the piston rod of the rice bag clamping lifting cylinder 81. A rice bag clamping bracket 82 is mounted at each end with a rice bag clamping adjustment cylinder 83. A rice bag clamping claw cylinder 84 is mounted on the piston rod of the rice bag clamping adjustment cylinder 83. The rice bag clamping lifting cylinder 81 drives the rice bag clamping bracket 82 to a predetermined height. The rice bag clamping claw cylinder 84 is moved to a predetermined position based on the size of the rice bag, adjusting the distance between the two rice bag clamping claw cylinders 84 to suit the size of the rice bag. The rice bag clamping claw cylinders 84 clamp the two ends of the rice bag, facilitating the opening of the rice bag to be opened by the rice bag turning and closing mechanism 9 and the rice bag fixing and closing mechanism 6.

[0065] The rice bag securing and closing mechanism 6 includes a rice bag securing and closing telescopic cylinder 61 mounted on the frame 1. The piston rod of the rice bag securing and closing telescopic cylinder 61 is connected to a rice bag securing and closing frame 62. The rice bag securing and closing frame 62 is equipped with a plurality of rice bag securing suction cups 63 for securing one side of the rice bag. The rice bag securing suction cups 63 are located on the side of the rice bag gripper cylinder 84 away from the rice bag flipping and closing frame 96. The rice bag securing and closing telescopic cylinder 61 pushes the rice bag securing and closing frame 62 out, and the plurality of rice bag securing suction cups 63 on the rice bag securing and closing frame 62 securely securely secure one side of the rice bag.

[0066] The rice bag turning and closing mechanism 9 includes a rice bag turning cylinder 91 mounted on the frame 1, to which a rice bag turning frame 92 is rotatably connected, a rice bag turning connecting rod 93 is fixed on the rice bag turning frame 92, a piston rod of the rice bag turning cylinder 91 is rotatably connected to the other end of the rice bag turning connecting rod 93, a rice bag first-level extending cylinder 94 is mounted on the rice bag turning frame 92, the piston rod of the rice bag first-level extending cylinder 94 is connected to the rice bag second-level extending cylinder 95, the piston rod of the rice bag second-level extending cylinder 95 is connected to the rice bag turning and closing frame 96, and a plurality of rice bag turning suction cups 97 for closing the other side of the rice bag are mounted on the rice bag turning and closing frame 96. When the rice bag turning and closing frame 96 is turned horizontally, it faces the bottom of the rice bag storage bin 12. When the rice bag turning and closing frame 96 is turned vertically, it faces the rice bag fixed suction mechanism 6.

[0067] The piston rods of the first and second rice bag extension cylinders 94 and 95 extend sequentially, allowing the several rice bag flipping suction cups 97 on the rice bag flipping and closing frame 96 to close the rice bags on the bottom layer of the rice bag storage compartment 12. The rice bag flipping cylinder 91 drives the rice bag flipping frame 92 to flip 90 degrees, allowing the rice bags to be flipped to a position directly opposite the rice bag securing and closing mechanism 6. At this point, the rice bag clamping unit 8 clamps both ends of the rice bag, and the rice bag securing and closing mechanism 6 closes the other side of the rice bag, thereby opening the rice bag. The rice bag flipping and closing mechanism 9 of the present invention automatically sucks in the rice bag and flips it to the packaging position, eliminating the need for manual operation.

[0068] A rice bag turning frame position detection sensor 98 is mounted on the frame 1, and a rice bag turning frame sensing plate 99 is fixed to the rice bag turning frame 92. When the rice bag turning and closing frame 96 rotates to face directly below the rice bag storage bin 12, the rice bag turning frame sensing plate 99 contacts the rice bag turning frame position detection sensor 98, ensuring that the rice bag turning and closing frame 96 can reliably suck up the rice bag.

[0069] The rice bag storage bin 12 includes a rice bag drop-out opening 121 provided on the frame 1. Rice bag baffles 122 are provided around the rice bag drop-out opening 121. These baffles 122 are spaced a certain distance from the edges of the rice bag drop-out opening 121 to ensure that the rice bags are supported on all sides of the rice bag drop-out opening 121. When a plurality of stacked rice bags are placed in the rice bag storage bin 12, the rice bag flipping suction cups 97 on the rice bag flipping and closing frame 96 suck the bottom rice bag and pull it out, while the remaining rice bags are still supported by the edges of the rice bag drop-out opening 121.

[0070] The vibration unit 7 includes a vibration lift cylinder 71 mounted on the frame 1. The piston rod of the vibration lift cylinder 71 is connected to a vibration mounting plate 72, to which a vibration plate 73 is rotatably connected. The vibration plate 73 is located below the rice bag clamping unit 8. A vibration cylinder 74 is mounted on the vibration mounting plate 72, and the piston rod of the vibration cylinder 74 is rotatably connected to the vibration plate 73. The vibration lift cylinder 71 can drive the vibration mounting plate to rise and fall, so that the vibration plate 73 can accurately support the bottom of the rice bag. After the vibration cylinder 74 is activated, the piston rod of the vibration cylinder 74 pulls the vibration plate 73 to tilt slightly up and down, thereby achieving the vibration effect of the vibration plate 73 on the rice bag, thereby evenly vibrating the rice within the rice bag.

[0071] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
