Description

Technical Field

[0001] The present invention relates to the technical field of rice production, and more particularly to automatic rice bagging and packaging equipment. Background Art

[0002] Rice is a staple food consumed widely around the world. It's the husked rice grain, primarily composed of carbohydrates, and is an important part of many people's daily diet. After undergoing a series of processes on the production line, including screening, stone removal, and impurity removal, rice enters the packaging stage. The specific packaging steps generally include: weighing, bagging, sealing, coding, testing, and packaging.

[0003] The rice bagging and delivery methods in the prior art are generally divided into two types according to the production scale: 1. In small-scale production processes, in order to save costs, a manual assisted method is generally used to open the rice bag, and then the bag mouth is placed on the outside of the discharge hopper of the rice loading equipment, and then the rice bag is clamped on the discharge hopper of the rice loading equipment by an automatic clamp for loading rice; 2. In large-scale production processes, a robotic arm and a suction cup are generally used to absorb and move the rice bag to the discharge hopper of the rice loading equipment, automatically open the rice bag, place the rice bag on the outside of the discharge hopper of the rice loading equipment, and then clamp the rice bag on the discharge hopper of the rice loading equipment by an automatic clamp for loading rice. However, both bag delivery methods have certain defects: First, when the rice bag is clamped only from the outside, the clamping force is mainly concentrated on the outer edge of the rice bag. This single-point or local clamping method cannot form a uniform support force distribution on the entire rice bag. During the rice loading process, as rice grains are continuously injected, the internal pressure of the rice bag gradually increases, and the outer clamping point may not be able to withstand this internal pressure, causing the rice bag to deflect or slip under uneven force.

[0004] Secondly, rice bags are usually made of soft cloth with certain elasticity and ductility. During the rice filling process, the rice bag will deform according to the distribution and weight changes of the rice grains inside. If it is only clamped from the outside, the deformation of the rice bag may not be effectively controlled. When the rice is filled at a fast speed, the bag mouth and bag body may easily loosen due to the impact of the rice grains inside. Summary of the Invention

[0005] The invention provides an automatic rice bagging and packaging device, which solves the technical problem in the prior art that the stability of the rice bag clamped from the outside needs to be improved.

[0007] The outer adsorption assembly includes two mounting plates that are symmetrical front and back and two sliding rods that are slidably mounted on the mounting plates and are symmetrical left and right.

[0014] Further, the translation and avoidance unit includes two pairs of second fixed seats fixedly installed on the frame and symmetrically arranged front and back, and a truss fixedly installed between the two pairs of second fixed seats and located at the bottom of the second fixed seats. A second driving motor is fixedly installed on the right side of the truss.

[0018] The beneficial effects of the present invention are: 1. The bag opening suction cup absorbs the bag opening from the outside to provide preliminary fixing force. At the same time, the inner support plate 1 and the inner support plate 2 open the bag opening from the inside to form a double clamping mechanism. This internal and external coordinated action mode greatly enhances the stability of the rice bag during the rice filling process and effectively prevents the bag opening from deflecting or slipping.

[0019] 2. By utilizing the movement of the bag opening suction cup to drive the expansion of the inner support plate 1 and the inner support plate 2, the inner support plate can be expanded at the same time as the rice bag is adsorbed. No additional power source or mechanism is required, achieving high efficiency and energy saving. In addition, the adsorption of the bag opening suction cup and the expansion of the inner support plate are carried out synchronously, which greatly shortens the preparation time of the entire bagging process and improves production efficiency.

[0020] 3. When the inner support plate 1 and the inner support plate 2 are expanded into place, the locking rod is simultaneously inserted into the locking groove to lock and fix the inner support plate 1, the inner support plate 2, the suction cup and the movable plate, thereby ensuring the relative position stability of each component during the rice filling process, avoiding the loosening or falling of the rice bag due to vibration or impact, and in the locked state, even in the event of an emergency or external force impact, the rice bag can remain stable to prevent the occurrence of problems such as rice bag rupture or rice leakage.

[0033] See Figure 1 and Figure 2In this embodiment, an automatic rice bagging and packaging device is proposed, including a conveyor belt 2, a sealer 5, a frame 1 mounted above the conveyor belt 2, and a liftable rice loading unit 4 fixedly mounted on the frame 1 via two left-right symmetrical fixing seats 3. A bag flipping and feeding unit 8, a translation avoidance unit 9, an inner and outer bag clamping unit 7, and a bag opening flattening unit 6 are provided between the conveyor belt 2 and the liftable rice loading unit 4. The inner and outer bag clamping unit 7 includes an outer suction component 701, a pulling component 702, an inner support locking component 703, and a squeezing component 704 for driving the inner support locking component 703 to cooperate with the outer suction component 701 to clamp and lock the bag.

[0034] See Figure 1 and Figure 5 The liftable rice loading unit 4 includes two pairs of guide rails 401 respectively fixedly mounted on one side of two fixed seats 3, a slider 402 is slidably connected to the outer side of the guide rail 401, a lifting frame 403 is commonly installed between the sliders 402 on the left and right sides, a hydraulic cylinder 404 is fixedly mounted on the top of the two fixed seats 3, the output ends of the two hydraulic cylinders 404 are fixedly connected to the lifting frame 403, a rice loading bucket 405 is fixedly mounted on the top of the lifting frame 403, a fixed guide plate 406 is fixedly mounted on the rear side of the rice loading bucket 405, an adjusting guide plate 408 is hinged to the bottom of the lifting frame 403 through a hinged frame 407, a cylinder 409 is hinged to the top of the lifting frame 403, and the output end of the cylinder 409 is hinged to the adjusting guide plate 408.

[0035] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The translation avoidance unit 9 includes two pairs of fixed seats 901 fixedly mounted on the frame 1 and symmetrically front and back, and a truss 902 fixedly mounted between the two pairs of fixed seats 901 and located at the bottom of the fixed seats 901. A driving motor 903 is fixedly mounted on the right side of the truss 902. A synchronous pulley 904 is rotatably mounted on the front side of the truss 902 and on the outer side of the output shaft of the driving motor 903. A synchronous belt 905 is commonly connected to the two synchronous pulleys 904 for transmission. A moving seat 906 is fixedly mounted on the outer side of the synchronous belt 905. Two guide rails 907 are fixedly mounted on the bottom of the truss 902 and are symmetrically front and back. Sliders 908 are slidably connected to the bottom of the two guide rails 907. A moving frame 909 fixedly connected to the moving seat 906 is commonly mounted between the two slides 908. Two mounting frames 910 symmetrically front and back are fixedly mounted on the bottom of the moving frame 909.

[0036] See Figure 1 、 Figure 2 and Figure 3Two adjustable mounting rods 10 are fixedly mounted on the mounting frame 910, and a baffle 11 is installed between the two adjustable mounting rods 10 on the same mounting frame 910. The front and rear baffles 11 are symmetrical to each other. Two baffles 13 that are symmetrical front and back and used to limit the rice bags are fixedly mounted on the support frame of the conveyor belt 2 through a number of L-shaped frames 12.

[0037] During specific use, the two hydraulic cylinders 404 are started, so that the output end of the hydraulic cylinder 404 pulls the lifting frame 403 to move upward. During the movement, the slider 402 slides along the guide rail 401 to maintain stability. The upward movement of the lifting frame 403 will drive the rice loading bucket 405 to move upward, thereby driving the fixed guide plate 406 and the adjustment guide plate 408 to move upward. At the same time, the driving motor 2 903 is started, and the output shaft of the driving motor 2 903 rotates to drive the right synchronous pulley 2 904 to rotate, thereby driving the synchronous belt 2 905 to transmit, and then driving the moving frame 909 to move to the right through the moving seat 906. During the movement, the slider 2 908 slides along the guide rail 2 907 to maintain stability, thereby driving the two mounting frames 910 to move to the right, causing the inner and outer bag clamping units 7 to move to the right to avoid, thereby making room for rice bag loading.

[0038] After making room for the rice bag to be loaded, the rice bag is flipped and moved to the left side of the two mounting racks 910 by flipping the bag feeding unit 8, and then the output shaft of the driving motor 2 903 is started to rotate to drive the right synchronous pulley 2 904 to rotate, thereby driving the synchronous belt 2 905 to transmit, and then the moving rack 909 is driven to move to the left through the moving seat 906, thereby driving the two mounting racks 910 to move to the left, so that the inner and outer bag clamping units 7 move to the left, and then the rice bag is located between the two mounting racks 910, then the bag mouth is opened and locked by the inner and outer bag clamping units 7, and then the two hydraulic cylinders 4 are started. 04, the output end of the hydraulic cylinder 404 pushes the lifting frame 403 to move downward, driving the rice loading hopper 405 to move downward, thereby driving the fixed guide plate 406 and the adjustable guide plate 408 to move downward and insert into the rice bag, and finally introducing rice into the rice loading hopper 405. The rice passes through the fixed guide plate 406 and the adjustable guide plate 408 and is loaded into the rice bag. After a single bagging is completed, the cylinder 1 409 is started, and the output end of the cylinder 1 409 pushes the adjustable guide plate 408 to rotate until the adjustable guide plate 408 and the fixed guide plate 406 are tightly closed and the rice stops flowing out.

[0039] After the rice is loaded, the lifting frame 403 is driven to move upward, driving the rice loading bucket 405 to move upward, thereby driving the fixed guide plate 406 and the adjustable guide plate 408 to move upward, and at the same time driving the output shaft of the second motor 903 to rotate to drive the right synchronous pulley 904 to rotate, thereby driving the synchronous belt 905 to drive the moving frame 909 to move to the right through the moving seat 906, and again moving the inner and outer bag clamping units 7 to the right to avoid, thereby making room for the rice bag to be loaded again, in preparation for the next rice loading operation.

[0040] See Figure 1 and Figure 6 The flipping and bag feeding unit 8 includes two U-shaped frames 801 fixedly mounted on the frame 1 and symmetrically on the left and right, and a rotating shaft 2 802 rotatably mounted between the two U-shaped frames 801. Two flip plates 803 are fixedly mounted on the outside of the rotating shaft 2 802. A cylinder 3 804 is installed between the two flip plates 803. A bag feeding suction cup 805 for adsorbing rice bags is fixedly mounted on the output end of the cylinder 3 804. A driving motor 3 806 with an output shaft fixedly connected to the rotating shaft 2 802 is fixedly mounted on the frame 1.

[0041] During specific use, in the initial state, the bag feeding suction cup 805 is facing downward, opposite to the external rice bag placement platform. After making room for the rice bag loading, the cylinder three 804 is started, and the output end of the cylinder three 804 pushes the bag feeding suction cup 805 to move downward, adsorbing the rice bag on the external rice bag placement platform. Then the output end of the cylinder three 804 contracts, driving the rice bag to separate from the rice bag placement platform. Next, the drive motor three 806 is started, and the output shaft of the drive motor three 806 drives the rotating shaft two 802 to rotate, thereby driving the flip plate 803 to flip 90°, flipping the rice bag to the left side of the two mounting racks 910. Next, the inner and outer bag clamping units 7 are controlled to move to the left, and then the bag opening is opened and locked by the inner and outer bag clamping units 7. After the bag opening is opened and locked, the bag feeding suction cup 805 releases the rice bag. At the same time, the output end of the cylinder three 804 contracts, so that the bag feeding suction cup 805 is separated from the rice bag, and then the rice loading operation is performed.

[0042] After the rice is loaded, the filled rice bag is transported to the right by the conveyor belt 2, and after making room for the next rice bag to be loaded, the drive motor 3 806 is started. The output shaft of the drive motor 3 806 rotates to drive the rotating shaft 2 802 to rotate, thereby driving the flip plate 803 to flip 90°, driving the bag feeding suction cup 805 to reset, and preparing to perform the bag feeding operation again.

[0043] See Figure 2 、 Figure 3 and Figure 7 The external adsorption component 701 includes two mounting plates 7011 fixedly mounted on the top of the two mounting frames 910 and symmetrical in front and back, and two sliding rods 7012 slidably mounted on the mounting plates 7011 and symmetrical in left and right. A movable plate 7013 is commonly installed between the two sliding rods 7012 on the same mounting plate 7011. Bag opening suction cups 7014 are fixedly mounted on the adjacent sides of the two movable plates 7013. Both the bag feeding suction cup 805 and the bag opening suction cup 7014 adopt existing porous vacuum suction cups, which disperse the vacuum suction force through multiple independent small holes to avoid the problem of insufficient adsorption stability caused by the pores on the rice bag.

[0044] See Figure 2 、 Figure 3 、 Figure 7 、 Figure 9 and Figure 10 The pulling component 702 includes a cylinder 2 7021 fixedly mounted on the front side of the front mounting plate 7011, and the output end slides through the front mounting plate 7011 and is fixedly connected to the front movable plate 7013. A fixed pulley 1 7022 is fixedly mounted on the right side of the front mounting plate 7011, and a pull rope 1 7023 is wound around the outer side of the fixed pulley 1 7022. The two ends of the pull rope 1 7023 are respectively fixedly connected to the front movable plate 7013 and the rear movable plate 7013. The rear ends of the two rear sliding rods 7012 are fixedly mounted with a circular plate 7024, and a return spring 3 7025 is jointly installed between the circular plate 7024 and the rear mounting plate 7011.

[0045] During specific use, when the two mounting frames 910 move to the left so that the rice bag is located between the two mounting frames 910, cylinder 2 7021 is started, and the output end of cylinder 2 7021 pushes the front movable plate 7013 to move backward, thereby driving the two front bag-opening suction cups 7014 to move backward. At the same time, during the backward movement of the front movable plate 7013, the front end of the pull rope 1 7023 is also pulled backward and the backward pulling force is converted into forward pulling force under the action of the fixed pulley 1 7022, thereby pulling the rear movable plate 7013 forward and causing the circular plate 7024 to compress the reset spring 3 7025, so that the two movable plates 7013 are close to each other, thereby causing the front and rear bag-opening suction cups 7014 to approach each other and suck the rice bag.

[0046] Then, the output end of cylinder 2 7021 contracts, and the front movable plate 7013 moves forward, thereby driving the two front bag-opening suction cups 7014 to move forward, and then driving the two front bag-opening suction cups 7014 to move forward and reset. During the forward movement of the front movable plate 7013, the pressure on the reset spring 3 7025 gradually decreases, thereby gradually resetting, driving the circular plate 7024 to move backward, thereby driving the rear movable plate 7013 to move backward through the two rear sliding rods 7012, and then driving the two rear bag-opening suction cups 7014 to move backward and reset, so that the front and rear bag-opening suction cups 7014 are synchronously moved away from and reset, and the mouth of the rice bag is opened.

[0047] See Figure 2 、 Figure 3 、 Figure 7 、 Figure 9 and Figure 10, the inner support locking component 703 includes two symmetric front and rear slide rails 7031 and a sliding plate 7032 slidably connected within the slide rails 7031. On the side away from each other of the two sliding plates 7032, an inner support plate one 7034 is fixedly installed through a push rod 7033 that slides through the slide rail 7031. On the left side of the inner support plate one 7034, an inner support plate two 7037 is fixedly installed through a connecting plate. The inner support locking component 703 further includes a first return spring 7036 fixedly installed between the side of the sliding plate 7032 close to the push rod 7033 and the inner wall of the slide rail 7031 and sleeved outside the push rod 7033. On the side close to each other of the two moving plates 7013, locking grooves 7030 are provided. Locking rods 7035 that cooperate with the corresponding locking grooves 7030 are fixedly installed on both the inner support plate one 7034 and the inner support plate two 7037. On the top of the two mounting plates 7011, limit plates 7038 with limit grooves are fixedly installed. On the side away from each other of the two inner support plates two 7037, limit rods 7039 that are slidably connected to the limit grooves on the same-side limit plates 7038 are respectively fixedly installed.

[0048] Refer to Figure 2 , Figure 3 , Figure 7 , Figure 9 and Figure 10 , the extrusion component 704 includes a U-shaped frame 7046 fixedly installed between the two mounting plates 7011 and located at the top of the two mounting plates 7011, and a second return spring 7041 fixedly installed on the top of the U-shaped frame 7046. The top of the second return spring 7041 is fixedly installed with a return plate 7042. At the bottom of the return plate 7042, a moving shaft 7043 is fixedly installed. A sleeve 7044 is slidably sleeved outside the moving shaft 7043. At the top of the sleeve 7044, a contact plate 7045 that cooperates with the U-shaped frame 7046 is fixedly installed. Both of the two slide rails 7031 are fixedly installed on the outside of the sleeve 7044 and are symmetric front and rear.

[0049] Refer to Figure 2 , Figure 3 , Figure 7 , Figure 9 and Figure 10 , on the inner walls of the front and rear sides of the U-shaped frame 7046, second fixed pulleys 7047 are fixedly installed. On the front and rear sides of the top of the U-shaped frame 7046, third fixed pulleys 7048 are fixedly installed. A second pull rope 7049 is commonly wound around the outside of the second fixed pulley 7047 and the third fixed pulley 7048 on the same side. The two ends of the second pull rope 7049 are respectively fixedly connected to the moving plate 7013 and the return plate 7042. At the bottom end of the moving shaft 7043, a trapezoidal block 7040 that cooperates with the sliding plate 7032 is fixedly installed. On the side of the sliding plate 7032 close to the trapezoidal block 7040, an inclined surface corresponding to the hypotenuse of the trapezoidal block 7040 is provided.

[0050] When in use, when the front and rear movable plates 7013 have not yet moved closer to each other, the front and rear movable plates 7013 are away from each other, the inner support plate 1 7034 is located between the two movable plates 7013, and the two inner support plates 1 7034 are in a state of moving away from each other. When the front and rear movable plates 7013 move closer to each other, the bottom ends of the pull ropes 2 7049 are pulled closer to each other synchronously. The pulling force of the pull ropes 2 7049 is converted into an upward pulling force under the action of the fixed pulleys 2 7047 and the fixed pulleys 3 7048, and the reset plate 7042 is pulled upward, and the reset spring 2 7041 is stretched at the same time, thereby pulling the movable shaft 7043 upward. During the upward movement of the movable shaft 7043, the trapezoidal block 7040 is first driven to move upward, and as the trapezoidal block 7040 moves upward, the reset plate 7042 is pulled upward. 7040 gradually moves upward, and the pressure on the two sliding plates 7032 gradually decreases. The reset spring 1 7036 drives the sliding plate 7032 to reset, and the inner support plate 1 7034 contracts and resets. At the same time, the inner support plate 2 7037 is driven to reset through the connecting plate to prevent the inner support plate 1 7034 from blocking the movement of the movable plate 7013. When the trapezoidal block 7040 moves to abut against the sleeve 7044, the movable shaft 7043 continues to move upward and will push the sleeve 7044 upward through the trapezoidal block 7040, thereby driving the inner support plate 1 7034 to move upward, and then driving the inner support plate 1 7034 to move upward from between the two movable plates 7013, further preventing the inner support plate 1 7034 from blocking the movement of the movable plate 7013, and then the movable plate 7013 drives the bag opening suction cup 7014 to adsorb the rice bag.

[0051] After the rice bag is adsorbed by the bag-opening suction cups 7014, when the output end of the second cylinder 7021 contracts to make the bag-opening suction cups 7014 on both the front and back sides move away synchronously and reset to open the mouth of the rice bag, first, the pressure on the second reset spring 7041 gradually decreases, pulling the reset plate 7042 downward to reset, which in turn drives the moving shaft 7043 downward. As the moving shaft 7043 gradually moves downward, the sleeve 7044 moves downward under the action of gravity. When the abutting plate 7045 at the top of the sleeve 7044 abuts against the top of the U-shaped frame 7046, the first inner support plate 7034 and the second inner support plate 7037 are inserted into the mouth of the rice bag and are opposite to the corresponding bag-opening suction cups 7014. At the same time, the locking rod 7035 is aligned with the corresponding locking groove 7030. Then, when the moving shaft 7043 continues to move, it will drive the trapezoidal block 7040 to squeeze the inclined surface of the sliding plate 7032, causing the two sliding plates 7032 to move away from each other and compress the first reset spring 7036, thereby pushing the two first inner support plates 7034 to move away from each other to support the bag mouth from the inside to the outside and abut against the bag-opening suction cups 7014. At the same time, at this moment, the locking rod 7035 is inserted into the corresponding locking groove 7030, thus achieving the locking between the first inner support plate 7034, the second inner support plate 7037 and the moving plate 7013, preventing the first inner support plate 7034, the second inner support plate 7037, the bag-opening suction cups 7014 and the moving plate 7013 from deflecting during the bagging process and causing the rice bag to slip. After the rice bag is filled, the first inner support plate 7034, the second inner support plate 7037 and the bag-opening suction cups 7014 are driven to release the internal and external clamping of the rice bag, allowing the rice bag to fall on the top of the conveyor belt 2.

[0052] Refer to Figure 2 、 Figure 4 and Figure 8 As shown in FIGS.

[0053] During specific use, the filled rice bag is released and falls on the top of the conveyor belt 2, and the rice bag is transported to the right through the conveyor belt 2. At the same time, the drive motor 606 is started, and the output shaft of the drive motor 606 rotates to drive the front rotating shaft 602 to rotate and drives the rear rotating shaft 602 and the front rotating shaft 602 to rotate relative to each other through gear engagement, thereby driving the two synchronous pulleys 604 to rotate relative to each other, and then driving the front and rear synchronous belts 605 to transmit relative to each other, so that the rice bag is squeezed and flattened by the two synchronous belts 605 when passing through the two synchronous belts 605 to the right, so that the front and rear sides of the bag opening are tightly attached. Finally, the rice bag is sewn and sealed by the sealer 5 and then sent out.

[0054] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
