Description
Technical Field
[0001] This invention belongs to the technical field of rice processing equipment, and relates to a rice bagging and packaging device, particularly a rice bagging and packaging device and its usage method. Background Technology
[0002] In the grain processing industry, bagging and packaging rice after processing is a crucial step in ensuring product storage, transportation, and sales. With the development of agricultural industrialization and large-scale production, traditional manual bagging and packaging methods can no longer meet the demands of large-volume, high-standard production, and automated bagging and packaging equipment is gradually becoming the industry mainstream.
[0003] Currently, rice bagging and packaging equipment on the market still has many shortcomings in practical applications: the stability of the bag supply and loading process is poor, the positioning accuracy of the packaging bags is low, and problems such as bag mouth deviation and skewing often occur, which makes it difficult to smoothly connect the subsequent bag opening and filling processes, requiring manual assistance to adjust and affecting the overall operation efficiency; the degree of automation is low, and there are interruptions and jams in the operation, and the degree of automation needs to be improved; the shaping and sewing mechanism does not have a good effect on the bag mouth, the sewing thread is uneven, and quality problems such as skipped stitches and missing stitches are prone to occur, which reduces the sealing and aesthetics of the packaging.
[0004] Therefore, we propose a rice bagging and packaging device and its usage method. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a rice bagging and packaging device and its usage method. The technical problem to be solved by this invention is: how to automate the quantitative bagging of rice through bag supply, clamping and dragging, positioning, bag delivery, bag opening, bag opening and transportation, quantitative filling, stable clamping and conveying, conveying, shaping and sewing, and conveying process, thereby improving overall operation efficiency and packaging stability.
[0006] The objective of this invention can be achieved through the following technical solutions: A rice bagging and packaging device and its usage method include a frame assembly, a conveying mechanism, and a bag feeding mechanism. The frame assembly includes a packaging frame, a material conveying frame at the upper front of the packaging frame, a bag feeding frame on the inner right side of the packaging frame, a quantitative material conveying mechanism on the material conveying frame extending into the packaging frame, a vertically mounted electric push rod nine on the bag feeding frame, a bag feeding roller below the telescopic end of the electric push rod nine, a bag picking mechanism on the rear side of the packaging frame located above the bag feeding mechanism, and a support mechanism on the lower inner side of the packaging frame. The packaging machine includes a centering mechanism located below the bag feeding rollers, a support mechanism located to the left of the centering mechanism, a conveying mechanism located in front of the support mechanism, and a centering mechanism located in front of the bag feeding mechanism. The inner top of the packaging machine frame is equipped with a shaping and sewing mechanism, a clamping and dragging mechanism, and a knife-inserting mechanism. The shaping and sewing mechanism is located above the support mechanism and in front of the quantitative feeding mechanism. The knife-inserting mechanism is located to the upper left of the centering mechanism, and the clamping and dragging mechanism is located directly above the feeding frame. A bag-opening mechanism is located to the left of the centering mechanism, to the right of the quantitative feeding mechanism, and the knife-inserting mechanism is located directly above the bag-opening mechanism.
[0007] The working principle of this invention is as follows: First, a bag supply mechanism provides packaging bags. Then, a bag retrieval mechanism picks up the packaging bags from the bag supply mechanism. Next, a clamping and dragging mechanism clamps the packaging bags from the bag retrieval mechanism and moves them to a centering mechanism. After the centering mechanism completes the centering and positioning of the packaging bags, the telescopic end of the electric push rod nine drives the bag feeding rollers on the bag feeding frame to abut against the packaging bags, thereby conveying the packaging bags to a bag opening mechanism. The bag opening mechanism simultaneously suctions the upper and lower sides of the bag opening, and an inserting mechanism inserts into the bag, clamping the front and rear sides of the packaging bags and moving them. The rice is conveyed to the quantitative feeding mechanism below, where it clamps the opening of the packaging bag and then feeds a measured amount of rice into the bag. During and after the rice is conveyed, the supporting mechanism supports the packaging bag and simultaneously vibrates it to ensure that the rice fully fills the bag and prevents it from tipping over. After the rice is conveyed, the supporting mechanism conveys the packaging bag containing the rice to the shaping and sewing mechanism, which shapes the opening of the bag. After the packaging bag is shaped and sewn, the conveying mechanism finally transports the packaged rice out.
[0008] The shaping and sewing mechanism includes a mounting frame, which is fixedly installed on the inner top front side of the packing machine frame. A drive motor is provided on the side of the mounting frame, and two shaping frames are provided on the lower end face of the mounting frame. A sewing machine is provided on one of the shaping frames, and a belt conveyor is provided at the lower end of each shaping frame. The output shaft of the drive motor is connected to the rotating shaft of one of the belt conveyors, and the rotating shafts of the two belt conveyors are connected by a gear pair.
[0009] With the above structure, the mounting frame is fixed to the top front side inside the packaging machine frame. The output shaft of the drive motor drives the rotating shaft of a belt conveyor connected to it to rotate. This rotating shaft drives the rotating shaft of another belt conveyor to rotate synchronously through a gear pair, so that the two belt conveyors symmetrically set at the lower end of the shaping frame can run in opposite directions. When the bag opening of the rice packaging bag is sent to this station, the two belt conveyors work together to clamp and transport the bag opening. During this process, the bag opening is sorted and flattened. At the same time, the sewing machine on one of the shaping frames completes the sewing operation of the bag opening. During the sewing process, the supporting mechanism drives the packaging bag and rice to move at a uniform speed to cooperate with the sewing process and ensure that the stitching is uniform and the sewing is stable and reliable.
[0010] The quantitative feeding mechanism includes a quantitative feeding hopper and a filling nozzle. The quantitative feeding hopper is fixedly installed between the upper end of the baling machine frame and the feeding frame. The filling nozzle is fixedly installed at the lower end of the baling machine frame. Both sides of the filling nozzle are hinged with duckbill plates and electric push rods 1. The telescopic ends of the electric push rods 1 are hinged to the duckbill plates on the same side. Each duckbill plate is hinged with a clamping top plate and an electric push rod 1. The electric push rod 1 is hinged to the clamping top plate on the same side.
[0011] Using the above structure, the quantitative feeding hopper fixed between the upper end of the baling machine frame and the feeding frame first completes the precise measurement of rice. When the packaging bag is sent to the fixed filling nozzle below it, the duckbill plates hinged on the left and right sides of the filling nozzle move under the drive of the corresponding electric push rods to adjust the shape of the filling channel. At the same time, the electric push rods hinged on each duckbill plate push the clamping top plate hinged on the same side to move, so that the clamping top plate and the duckbill plate cooperate to stably clamp the bag opening from the inside and outside. After the bag opening is firmly clamped, the measured material is smoothly poured into the bag from the quantitative feeding hopper through the filling nozzle, thus completing the quantitative filling operation.
[0012] The bag feeding mechanism includes a bag feeding frame, with several clearance holes on the upper surface of the bag feeding frame. The bag feeding frame has a slide rail inside, and a slide block is slidably mounted on the slide rail. Several push plates are mounted on the slide block, and the number and position of the push plates match the clearance holes. All push plates pass through the clearance holes at the corresponding positions. An electric push rod is fixed to the side of the bag feeding frame, and the telescopic end of the electric push rod is fixedly connected to the slide block.
[0013] With the above structure, the packaging bags are stacked and placed on the upper surface of the bag feeding machine frame. The slide seat 1, which is slidably set on the slide rail 1 inside, is connected to the telescopic end of the electric push rod 2, which is fixed on the side of the frame. When it is necessary to replenish the bags, the electric push rod 2 pushes the slide seat 1 to slide forward along the slide rail 1, which drives several push plates fixed on the slide seat 1 to move forward synchronously. These push plates pass through the corresponding clearance holes 1 opened on the upper surface of the bag feeding machine frame, thereby smoothly pushing the entire stack of packaging bags to the preset position, ensuring that the top layer of packaging bags on the top of the stack is always accurately in the set position, so that the bag picking mechanism above can stably and reliably pick up individual packaging bags, and continuously provide materials for the subsequent automated process.
[0014] The centering mechanism includes a centering frame, on which several clearance holes are provided. Several guide rods are fixed inside the centering frame. The number and position of the clearance holes match the guide rods. Two electric push rods are fixed on each guide rod, arranged symmetrically front to back. A centering bracket is fixed on the telescopic end of the electric push rod. The centering bracket passes through the clearance holes at the corresponding positions.
[0015] With the above structure, when the packaging bag is moved to the preset position above the centering frame, the centering program is started. The electric push rods three fixed on several guide rods inside the centering frame move simultaneously. Their telescopic ends move synchronously towards each other, driving the centering brackets fixed at their ends to move smoothly along the direction of the guide rods. Each centering bracket passes through the corresponding clearance hole two opened on the centering frame, thus extending from the left and right sides of the packaging bag and contacting the bag body. Through the coordinated pushing or pulling of the electric push rods three on both sides, the centering brackets can adjust the lateral position of the packaging bag so that its center line is precisely aligned with the preset filling center line. After the positioning is completed, the mechanism resets, providing a packaging bag with accurate positioning for subsequent bag feeding or bag opening processes.
[0016] The supporting mechanism includes a supporting frame, with horizontally arranged guide rails on both the left and right sides of the supporting frame. Sliding blocks are mounted on the guide rails, and a supporting plate is positioned between the two sliding blocks. An electric push rod six is fixed to the inner bottom of the supporting frame, with its telescopic end fixedly connected to the supporting plate. A fixed plate, an electric push rod five, and two symmetrically arranged clamping assemblies are located at the upper end of the supporting plate. The fixed plate is situated between the two clamping assemblies and has a rotatable connecting piece. Each clamping assembly includes a support plate with clearance openings. A clamping frame is hinged to the upper end of the support plate, and an electric push rod four is fixed to the inner side of the clamping frame. A clamping rod is provided on the telescopic end of push rod four. A connecting rod one is fixed on the hinge shaft of the clamping frame. Connecting rod one passes through the clearance opening, and connecting rod three is hinged between the end of connecting rod one and the connecting piece. Two connecting rods two are hinged between the clamping frame and the support plate, arranged symmetrically in front and behind. A connecting seat is fixed on the rear side of the support plate. A rotating plate is hinged on the upper end of the connecting seat. Connecting rod four is hinged between the rotating plate and the connecting seat. An arc-shaped clamping plate is fixed on the upper end of the rotating plate. An electric push rod eleven is fixed on the connecting seat. The telescopic end of the electric push rod eleven is hinged to the rotating plate on the same side. A vibration seat is fixed on the upper end of the support plate. The vibration seat is located between the two clamping components.
[0017] With the above structure, during operation, the packaging bag to be filled falls onto the vibrating seat, and two symmetrically arranged clamping components begin to work in tandem: On one hand, in each clamping component, the electric push rod four fixed inside the clamping frame drives the clamping rod to rise and fall, adjusting the height of the clamping rod to clamp the bag from both sides. On the other hand, this action is transmitted through the hinge shaft of the clamping frame and the fixed connecting rod one. Connecting rod one passes through the clearance opening on the support plate and is connected to the rotating connector on the fixed plate through connecting rod three, thereby ensuring the linkage and symmetry of the clamping actions on both sides. At the same time, the two connecting rods two hinged between the clamping frame and the support plate play a stabilizing and guiding role. To prevent the packaging bag from tilting backward during filling and vibration, the electric push rod eleven on the rear connecting seat of the support plate is activated, driving the rotating plate hinged to it to rotate. The arc-shaped clamping plate at the top of the rotating plate then closes forward, clamping the body of the packaging bag from the rear. This is transmitted and constrained through the connecting rod four hinged between the rotating plate and the connecting seat. With the packaging bag reliably clamped and held, the vibrating seat fixed between the two clamping components on the support plate is activated, generating high-frequency micro-amplitude vibration, which compacts the material filled into the bag. After the filling and compaction processes are completed, the electric push rod six drives the support plate to move horizontally, thereby transferring the fully loaded packaging bag laterally to the next process.
[0018] The inserting knife mechanism includes a mounting plate 1, which is set at the top inside the packing machine frame. On the left side of the mounting plate 1, there are two inserting knife supports arranged symmetrically front to back. A rotating shaft 1 is rotatably connected between the two inserting knife supports. A drive motor 2 is fixed to the side of one of the inserting knife supports. The output shaft of the drive motor 2 is connected to the rotating shaft 1. An inserting knife holder and a clamping plate are fixed on the rotating shaft 1. The end of the inserting knife holder is fixed to the rotating shaft 2. Two open inserting knives arranged symmetrically front to back are fixed at both ends of the rotating shaft 2. An electric push rod 7 is hinged between the rotating shaft 2 and the inserting knife holder. The end of the clamping plate is fixed to the rotating shaft 3. Two clamping rods arranged symmetrically front to back are fixed on the rotating shaft 3. The end of each clamping rod is provided with two gear clamps that can mesh with each other. One end of the gear clamp is a half gear, and the other end of the gear clamp is a clamping plate.
[0019] With the above structure, mounting plate 1 is fixed to the top of the packaging machine frame. Rotating shaft 1, which is rotatably set between the two insert knife brackets on its left side, is driven to rotate by drive motor 2 on the side of one of the insert knife brackets. During operation, the output shaft of drive motor 2 drives rotating shaft 1 to rotate by a certain angle, causing the two open insert knives at the front end of the insert knife bracket and the two clamping rods at the front end of the clamping plate to swing downward and insert into the already opened packaging bag opening. Then, electric push rod 7, which is hinged between rotating shaft 2 and insert knife bracket, actuates, pushing rotating shaft 2 and the two open insert knives fixed thereon to rotate relative to insert knife bracket, adjusting the insert knife angle to better penetrate into the bag and slightly open the bag opening. Subsequently, the two gear clamping plates at the end of the clamping rods begin to work, with their half gear ends meshing and rotating, driving the clamping plates at the other end to move towards each other, thereby firmly clamping the front and rear sides of the packaging bag. Finally, the output shaft of drive motor 2 drives rotating shaft 1 to rotate, using the clamping rods clamping the bag sides to drag the entire packaging bag to the accurate filling position below the quantitative feeding mechanism, completing the continuous action of opening, holding, and feeding the bag.
[0020] The bag-opening mechanism includes a mounting rod and a second mounting plate. The mounting rod is fixedly mounted on a crossbeam in the middle of the inside of the packing machine frame. An electric push rod is provided on the front side of the mounting rod. A bag-opening frame is provided on the telescopic end of the electric push rod. The second mounting plate is fixedly mounted on the left side of the centering frame. A guide plate is provided on the upper end of the second mounting plate. A second bag-opening frame is provided on the left side of the second mounting plate. The second bag-opening frame and the first bag-opening frame are arranged symmetrically. Both the second bag-opening frame and the first bag-opening frame are provided with two bag-opening suction cups arranged symmetrically from left to right. The bag-opening suction cups are connected to an external vacuum pump through a multi-way valve.
[0021] Using the above structure, when the packaging bag is positioned by the centering mechanism, the telescopic end of the electric push rod nine drives the bag feeding roller on the bag feeding frame to abut against the packaging bag. Through the friction of the bag feeding roller, the bag is guided by the guide plate at the upper end of the mounting plate two, so that the packaging bag reaches the opening position, ensuring that the bag opening can be opened smoothly and accurately to the predetermined shape and size. The electric push rod eight, which is fixed on the crossbeam in the middle position inside the packaging machine frame, is activated, driving the opening frame one on its telescopic end to move downward. At the same time, the opening frame two, which is fixed on the mounting plate two on the left side of the centering frame, remains stationary or is finely adjusted according to the command. The external vacuum pump is activated through the multi-way valve, so that the opening suction cups on the opening frame one and the opening frame two respectively adhere to the upper and lower surfaces of the packaging bag opening. Then, the electric push rod eight retracts, pulling the opening frame one upward, thereby opening the bag opening and preparing for the subsequent insertion and operation of the opening inserter.
[0022] The clamping mechanism includes an electric lead screw component, with connecting plates at both ends of the electric lead screw component. The connecting plates are all located on the inner top right side of the packing machine frame. An installation rod is fixed on the lead screw slide of the electric lead screw component, and several equally spaced electric grippers are fixed on the installation rod.
[0023] With the above structure, after the bag-picking mechanism picks up the packaging bag and lifts it to a predetermined height, the mounting rod installed on the screw slide of the electric screw component, through the synchronous action of several equally spaced electric grippers, clamps the bag opening from both sides or above. Subsequently, the electric screw component starts, driving its screw slide to move precisely in the horizontal direction, thereby causing the packaging bag held by the electric grippers to move horizontally as a whole, stably and linearly dragging the packaging bag from the bag-picking station located above the bag-feeding mechanism to the designated position above the centering mechanism in front, completing the station transfer of the packaging bag and preparing for the subsequent centering, bag feeding and bag opening processes.
[0024] The bag-retrieving mechanism includes an electric push rod twelve, with a suction cup frame fixed to the telescopic end of the electric push rod twelve. The suction cup frame is provided with several vacuum suction cups distributed at equal intervals, and the vacuum suction cups are connected to an external vacuum pump through a multi-way valve.
[0025] With the above structure, when a bag-retrieving command is received, the suction cup frame fixed to the telescopic end of the electric push rod 12 first descends, causing several vacuum suction cups on it to contact the surface of the top layer of packaging bag in the bag supply mechanism. Subsequently, the external vacuum pump is started through the multi-way valve, causing all vacuum suction cups to generate negative pressure simultaneously, thereby reliably adsorbing a single packaging bag. After the adsorption is firm, the telescopic end of the electric push rod 12 retracts, raising the suction cup frame and the suctioned packaging bag to a predetermined height. Finally, the mechanism transfers the packaging bag or hands it over to the subsequent clamping and dragging mechanism for handover, thus completing one bag-retrieving operation.
[0026] Compared with existing technologies, this rice bagging and packaging device and its usage method have the following advantages: 1. Through the automatic pushing of bag stacks by the bag feeding mechanism, the precise bag picking by the bag picking mechanism, the horizontal transfer by the clamping and dragging mechanism, the centering and positioning by the centering mechanism, and the coordinated conveying of the electric push rod nine of the bag feeding frame with the bag feeding rollers, the packaging bags are automatically, continuously transferred and positioned from the pallet to the bag opening station, thereby improving the efficiency and reliability of the bag feeding and bag loading process.
[0027] 2. The bag opening mechanism achieves stable adsorption and opening of the bag mouth; the inserting mechanism inserts, expands and firmly clamps the bag mouth, and delivers the bag to the filling position; the quantitative feeding mechanism clamps the bag mouth and performs quantitative filling at the filling nozzle; the supporting mechanism supports the bag body from the bottom, clamps it from the side and holds it from the rear during the filling and compaction process to prevent tipping and ensure the dense filling of the material, thus ensuring stable filling operation.
[0028] 3. The shaping and sewing mechanism completes the sorting and flattening, and works with the sewing machine to achieve stable sewing. Finally, the finished product is automatically output through the conveying mechanism. The various mechanisms are highly integrated based on the packaging frame and are linked in an orderly manner through electrical and pneumatic control to form a highly efficient, continuous, and automated rice bagging and packaging device, which reduces labor costs and labor intensity, and ensures the consistency of packaging quality.

[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.
[0045] like Figures 1-14As shown, this rice bagging and packaging device and its usage method include a frame assembly 1, a conveying mechanism 3, and a bag feeding mechanism 7. The frame assembly 1 includes a packaging frame 10. A material conveying frame 9 is provided on the upper front side of the packaging frame 10. A bag feeding frame 11 is provided on the inner right side of the packaging frame 10. A quantitative material conveying mechanism 52 is provided on the material conveying frame 9, and the quantitative material conveying mechanism 52 extends into the interior of the packaging frame 10. A vertically arranged electric push rod 9 is provided on the bag feeding frame 11. A bag feeding roller is provided below the telescopic end of the electric push rod 9. A bag picking mechanism 8 is provided on the rear side of the packaging frame 10. The bag picking mechanism 8 is located above the bag feeding mechanism 7. The bag feeding mechanism 7 is located on the rear side of the packaging frame 10. A bag feeding mechanism 8 is provided on the lower part of the interior of the packaging frame 10. The packaging machine frame 10 has a supporting mechanism 4 and a centering mechanism 5. The centering mechanism 5 is located below the bag feeding roller, and the supporting mechanism 4 is located to the left of the centering mechanism 5. The conveying mechanism 3 is located in front of the supporting mechanism 4, and the centering mechanism 5 is located in front of the bag feeding mechanism 7. The inner top of the packaging machine frame 10 is equipped with a shaping and sewing mechanism 2, a clamping and dragging mechanism 6, and a knife insertion mechanism. The shaping and sewing mechanism 2 is located above the supporting mechanism 4 and in front of the quantitative feeding mechanism 52. The knife insertion mechanism is located to the upper left of the centering mechanism 5. The clamping and dragging mechanism 6 is located directly above the feeding frame 9. The left side of the centering mechanism 5 is equipped with a bag opening mechanism, which is located to the right of the quantitative feeding mechanism 52. The knife insertion mechanism is located directly above the bag opening mechanism.
[0046] In this embodiment, the bag supply mechanism 7 first provides the packaging bag, then the bag retrieval mechanism 8 picks up the packaging bag from the bag supply mechanism 7, and then the clamping and dragging mechanism 6 clamps the packaging bag from the bag retrieval mechanism 8 and moves the packaging bag to the centering mechanism 5. After the centering mechanism 5 completes the centering and positioning of the packaging bag, the telescopic end of the electric push rod nine drives the bag feeding roller on the bag feeding frame 11 to abut against the packaging bag, thereby conveying the packaging bag to the bag opening mechanism. The bag opening mechanism simultaneously sucks up the upper and lower sides of the bag opening, and the inserting knife mechanism inserts into the bag, clamping the front and rear sides of the packaging bag and moving the packaging bag to the bag opening mechanism. Below the quantitative feeding mechanism 52, the quantitative feeding mechanism 52 clamps the opening of the packaging bag and then quantitatively feeds rice into the bag. During and after the rice is fed, the supporting mechanism 4 supports the packaging bag and simultaneously performs vibration to ensure that the rice fully fills the packaging bag and prevents the packaging bag from tipping over. After the rice is fed, the supporting mechanism 4 transports the packaging bag containing rice to the shaping and sewing mechanism 2. The shaping and sewing mechanism 2 shapes the opening of the bag. After the packaging bag is shaped and sewn, the conveying mechanism 3 finally transports the packaged rice out.
[0047] The shaping and sewing mechanism 2 includes a mounting frame 12, which is fixedly installed on the inner top front side of the packing machine frame 10. A drive motor 13 is provided on the side of the mounting frame 12. Two shaping frames are symmetrically arranged on the lower end face of the mounting frame 12. A sewing machine 16 is provided on one of the shaping frames. A belt conveyor 15 is provided at the lower end of each shaping frame. The output shaft of the drive motor 13 is connected to the rotating shaft of one of the belt conveyors 15. The rotating shafts of the two belt conveyors 15 are connected by a gear pair.
[0048] In this embodiment, the mounting frame 12 is fixed to the top front side inside the packaging machine frame 10. The output shaft of the drive motor 13 drives the rotating shaft of a belt conveyor 15 connected to it to rotate. This rotating shaft drives the rotating shaft of another belt conveyor 15 to rotate synchronously through a gear pair, so that the two belt conveyors 15, which are symmetrically arranged at the lower end of the shaping frame, can run in opposite directions. When the bag opening of the rice packaging bag is sent to this station, the two belt conveyors 15 work together to clamp and transport the bag opening. During this process, the bag opening is sorted and flattened. At the same time, the sewing machine 16 on one of the shaping frames completes the sewing operation of the bag opening. When sewing, the supporting mechanism 4 drives the packaging bag and rice to move at a uniform speed to cooperate with the sewing process and ensure that the stitching is uniform and the sewing is stable and reliable.
[0049] The quantitative feeding mechanism 52 includes a quantitative feeding hopper 17 and a filling nozzle 19. The quantitative feeding hopper 17 is fixedly installed between the upper end of the baling machine frame 10 and the feeding frame 9. The filling nozzle 19 is fixedly installed at the lower end of the baling machine frame 10. Both sides of the filling nozzle 19 are hinged with duckbill plates and electric push rods 10. The telescopic ends of the electric push rods 10 are hinged to the duckbill plates on the same side. Each duckbill plate is hinged with a clamping top plate 53 and an electric push rod 18. The electric push rod 18 is hinged to the clamping top plate 53 on the same side.
[0050] In this embodiment, the quantitative feeding hopper 17, fixed between the upper end of the packaging frame 10 and the feeding frame 9, first completes the precise measurement of rice. When the packaging bag is sent to the fixed filling nozzle 19 below it, the duckbill plates hinged on the left and right sides of the filling nozzle 19 move under the drive of the corresponding electric push rod 10 to adjust the shape of the filling channel. At the same time, the electric push rod 18 hinged on each duckbill plate pushes the clamping top plate 53 hinged on the same side to move, so that the clamping top plate 53 and the duckbill plate cooperate to stably clamp the bag opening from the inside and outside. After the bag opening is firmly clamped, the measured material is smoothly poured into the bag from the quantitative feeding hopper 17 through the filling nozzle 19, thereby completing the quantitative filling operation.
[0051] The bag feeding mechanism 7 includes a bag feeding frame 20. The upper end face of the bag feeding frame 20 is provided with several clearance holes. The bag feeding frame 20 is provided with a slide rail. A slide seat 23 is slidably mounted on the slide rail. Several push plates 22 are mounted on the slide seat 23. The number and position of the push plates 22 match the clearance holes. All push plates 22 pass through the clearance holes at the corresponding positions. An electric push rod 21 is fixed to the side of the bag feeding frame 20. The telescopic end of the electric push rod 21 is fixedly connected to the slide seat 23.
[0052] In this embodiment, the stack of packaging bags is placed on the upper surface of the bag feeding machine frame 20. The slide block 23, which is slidably mounted on the slide rail 1 inside the frame, is connected to the telescopic end of the electric push rod 21 fixed on the side of the frame. When it is necessary to replenish the bag supply, the electric push rod 21 pushes the slide block 23 to slide forward along the slide rail 1, which drives several push plates 22 fixed on the slide block 23 to move forward synchronously. These push plates 22 pass through the corresponding clearance holes 1 opened on the upper surface of the bag feeding machine frame 20, thereby smoothly pushing the entire stack of packaging bags to the preset position, ensuring that the topmost packaging bag on the top of the stack is always accurately in the set position, so that the bag picking mechanism 8 above can stably and reliably pick up individual packaging bags, and continuously provide materials for the subsequent automated process.
[0053] The centering mechanism 5 includes a centering frame 24, which has several clearance holes 2. Several guide rods 25 are fixed inside the centering frame 24. The number and position of the clearance holes 2 match the guide rods 25. Two electric push rods 3 26 are fixed on each guide rod 25. A centering bracket 27 is fixed on the telescopic end of the electric push rod 3 26. The centering brackets 27 pass through the clearance holes 2 at the corresponding positions.
[0054] In this embodiment, after the packaging bag is moved to the preset position above the centering frame 24, the centering program is started. The electric push rods 26 fixed on several guide rods 25 inside the centering frame 24 move simultaneously. Their telescopic ends move synchronously towards each other, driving the centering brackets 27 fixed at their ends to move smoothly along the direction of the guide rods 25. Each centering bracket 27 passes through the corresponding clearance hole 2 opened on the centering frame 24, thereby extending from the left and right sides of the packaging bag and contacting the bag body. Through the coordinated pushing or pulling of the electric push rods 26 on both sides, the centering brackets 27 can adjust the lateral position of the packaging bag so that its center line is precisely aligned with the preset filling center line. After the positioning is completed, the mechanism resets, providing a packaging bag with accurate position for the subsequent bag feeding or bag opening process.
[0055] The supporting mechanism 4 includes a supporting frame 28. Horizontally arranged guide rails 29 are provided on both the left and right sides of the supporting frame 28. Slide seats 30 are slidably mounted on each guide rail 29. A supporting plate is located between the two slide seats 30. An electric push rod 40 is fixed to the inner bottom of the supporting frame 28. The telescopic end of the electric push rod 40 is fixedly connected to the supporting plate. A fixing plate 38, an electric push rod 37, and two symmetrically arranged clamping assemblies 31 are provided at the upper end of the supporting plate. The fixing plate 38 is located between the two clamping assemblies 31. A connecting piece 39 is rotatably mounted on the fixing plate 38. Each clamping assembly 31 includes a support plate with clearance openings. A clamping frame is hinged to the upper end of the support plate, and an electric push rod is fixed to the inner side of the clamping frame. The telescopic end of the electric push rod 32 is equipped with a clamping rod 33. A connecting rod 14 is fixed on the hinge shaft of the clamping frame. The connecting rod 14 passes through the clearance opening, and the end of the connecting rod 14 is hinged to the connecting member 39 with a connecting rod 3. Two connecting rods 24 are hinged between the clamping frame and the support plate and are arranged symmetrically in front and behind. A connecting seat is fixed on the rear side of the support plate. A rotating plate is hinged to the upper end of the connecting seat. A connecting rod 4 is hinged between the rotating plate and the connecting seat. An arc-shaped clamping plate 36 is fixed to the upper end of the rotating plate. An electric push rod 11 is fixed on the connecting seat. The telescopic end of the electric push rod 11 is hinged to the rotating plate on the same side. A vibration seat 35 is fixed to the upper end of the support plate. The vibration seat 35 is located between the two clamping components 31.
[0056] In this embodiment, during operation, the packaging bag to be filled falls onto the vibrating seat 35, and two symmetrically arranged clamping components 31 begin to work in concert: on the one hand, in each clamping component 31, the electric push rod 32 fixed inside the clamping frame drives the clamping rod 33 to rise and fall, adjusting the height of the clamping rod 33 to clamp the bag from both sides. On the other hand, this action is transmitted through the hinge shaft of the clamping frame and the fixed connecting rod 14. The connecting rod 14 passes through the clearance opening on the support plate and is connected to the rotating connecting piece 39 on the fixed plate 38 through the connecting rod 3, thereby ensuring the linkage and symmetry of the clamping action on both sides. At the same time, the two connecting rods 2 34 hinged between the clamping frame and the support plate play a role in... For stabilization and guidance, to prevent the packaging bag from tilting backward during filling and vibration, the electric push rod eleven on the rear connecting seat of the support plate is activated, driving the rotating plate hinged to it to rotate. The arc-shaped clamping plate 36 at the upper end of the rotating plate then closes forward, clamping the body of the packaging bag from the rear. This is transmitted and constrained through the connecting rod four hinged between the rotating plate and the connecting seat. With the packaging bag reliably clamped and held, the vibration seat 35 fixed between the two clamping components 31 on the support plate is activated, generating high-frequency micro-amplitude vibration, which compacts the material filled into the bag. After the filling and compaction processes are completed, the electric push rod six 40 drives the support plate to move horizontally, thereby transferring the fully loaded packaging bag laterally to the next process.
[0057] The inserting knife mechanism includes a mounting plate 41, which is set at the top inside the packing machine frame 10. Two inserting knife supports 42 are symmetrically arranged on the left side of the mounting plate 41. A rotating shaft 43 is rotatably connected between the two inserting knife supports 42. A drive motor 2 is fixed to the side of one of the inserting knife supports 42. The output shaft of the drive motor 2 is connected to the rotating shaft 43. An inserting knife holder and a clamping plate holder are fixed on the rotating shaft 43. The rotating shaft 2 is fixed to the end of the inserting knife holder. Two open inserting knives 44 are fixed to both ends of the rotating shaft 2. An electric push rod 46 is hinged between the rotating shaft 2 and the inserting knife holder. A rotating shaft 3 is fixed to the end of the clamping plate holder. Two clamping rods 45 are fixed to the rotating shaft 3. Each clamping rod 45 has two meshing gear clamps at its end. One end of the gear clamp is a half gear, and the other end of the gear clamp is a clamping plate.
[0058] In this embodiment, mounting plate 41 is fixed to the top of the packaging machine frame 10. A rotating shaft 43, rotatably mounted between the two insert knife brackets 42 on its left side, is driven to rotate by a drive motor 2 on the side of one of the insert knife brackets 42. During operation, the output shaft of drive motor 2 drives the rotating shaft 43 to rotate by a certain angle, causing the two open insert knives 44 at the front end of the insert knife bracket and the two clamping rods 45 at the front end of the clamping plate frame to swing downwards and insert into the opened packaging bag opening. Then, the electric push rod 46, hinged between the rotating shaft 2 and the insert knife bracket, actuates, pushing the rotating shaft 2... The two open inserts 44 fixed on it rotate relative to the insert holder, adjusting the insert angle to better penetrate into the bag and slightly open the bag opening. Then, the two gear clamps at the end of the clamping rod 45 start to work, with their half gear ends meshing and rotating, driving the clamping plates at the other end to move towards each other, thereby firmly clamping the front and rear sides of the packaging bag. Finally, the output shaft of the second drive motor drives the rotating shaft 43 to rotate, using the clamping rod 45 that clamps the bag sides to drag the entire packaging bag to the accurate filling position below the quantitative feeding mechanism 52, completing the continuous action of opening, holding and feeding the bag.
[0059] The bag-opening mechanism includes a mounting rod 50 and a mounting plate 47. The mounting rod 50 is fixedly mounted on a crossbeam in the middle of the inside of the packing machine frame 10. An electric push rod 49 is provided on the front side of the mounting rod 50. A bag-opening frame 54 is provided on the telescopic end of the electric push rod 49. The mounting plate 47 is fixedly mounted on the left side of the centering frame 24. A guide plate 51 is provided on the upper end of the mounting plate 47. A bag-opening frame 55 is provided on the left side of the mounting plate 47. The bag-opening frame 55 and the bag-opening frame 54 are arranged symmetrically from top to bottom. Both the bag-opening frame 55 and the bag-opening frame 54 are provided with two bag-opening suction cups 48 arranged symmetrically from left to right. The bag-opening suction cups 48 are connected to an external vacuum pump through a multi-way valve.
[0060] In this embodiment, when the packaging bag is positioned by the centering mechanism 5, the telescopic end of the electric push rod nine drives the bag feeding roller on the bag feeding frame 11 to abut against the packaging bag. Through the friction of the bag feeding roller, the bag is guided by the guide plate 51 at the upper end of the mounting plate two 47, so that the packaging bag reaches the opening position, ensuring that the bag opening can be opened smoothly and accurately to the predetermined shape and size. The electric push rod eight 49 on the front side of the mounting rod 50 fixed on the crossbeam in the middle position inside the packaging machine frame 10 is activated, driving the opening frame one 54 on its telescopic end to move downward. At the same time, the opening frame two 55 on the mounting plate two 47 fixed on the left side of the centering machine frame 24 remains stationary or is finely adjusted according to the command. The external vacuum pump is activated through the multi-way valve, so that the opening suction cups 48 on the opening frame one 54 and the opening frame two 55 respectively adsorb the upper and lower surfaces of the packaging bag opening. Subsequently, the electric push rod eight 49 retracts, pulling the opening frame one 54 upward, thereby opening the bag opening and preparing for the subsequent insertion and operation of the opening inserter.
[0061] The clamping mechanism 6 includes an electric lead screw 58. Both ends of the electric lead screw 58 are provided with connecting plates 57. The connecting plates 57 are all located on the inner top right side of the packing machine frame 10. An installation rod 61 is fixed on the lead screw slide of the electric lead screw 58. Several electric grippers 56 are fixed on the installation rod 61 at equal intervals.
[0062] In this embodiment, after the bag-picking mechanism 8 picks up the packaging bag and lifts it to a predetermined height, the mounting rod 61 installed on the screw slide of the electric screw component 58, through the synchronous action of several equally spaced electric grippers 56, clamps the bag opening from both sides or above. Subsequently, the electric screw component 58 is activated, driving its screw slide to move precisely in the horizontal direction, thereby causing the packaging bag held by the electric grippers 56 to move horizontally as a whole, stably and linearly dragging the packaging bag from the bag-picking station located above the bag-feeding mechanism 7 to the designated position above the centering mechanism 5 in front, completing the station transfer of the packaging bag and preparing for the subsequent centering, bag feeding and bag opening processes.
[0063] The bag-retrieving mechanism 8 includes an electric push rod 12 59. A suction cup frame 60 is fixed on the telescopic end of the electric push rod 12 59. The suction cup frame 60 is provided with several vacuum suction cups 62 that are evenly distributed. The vacuum suction cups 62 are connected to an external vacuum pump through a multi-way valve.
[0064] In this embodiment, when a bag-retrieving command is received, the suction cup frame 60 fixed on the telescopic end of the electric push rod 12 59 first descends, causing several vacuum suction cups 62 on it to contact the surface of the uppermost packaging bag of the bag supply mechanism 7. Subsequently, the external vacuum pump is started through the multi-way valve, causing all the vacuum suction cups 62 to generate negative pressure simultaneously, thereby reliably adsorbing a single packaging bag. After the adsorption is firm, the telescopic end of the electric push rod 12 59 retracts, raising the suction cup frame 60 and the suctioned packaging bag to a predetermined height. Finally, the mechanism transfers the packaging bag or hands it over to the subsequent clamping and dragging mechanism 6 for handover, thereby completing one bag-retrieving operation.
[0065] The method of using this invention is as follows: First, the stacked packaging bags are placed on the bag feeding frame 20 of the bag feeding mechanism 7. The electric push rod 21 inside pushes the slide 23 and the push plate 22 to push the stack of bags forward to the bag picking position. Then, the electric push rod 59 of the bag picking mechanism 8 drives the suction cup frame 60 to descend. The vacuum suction cup 62 on it is connected to the vacuum pump through a multi-way valve. Then, the vacuum suction cup 62 adsorbs the top layer of packaging bags and is lifted to the preset position by the extension end of the electric push rod 59. Next, the clamping and dragging mechanism 6 is activated. The electric gripper 56 clamps the packaging bag. The screw slide of the electric screw component 58 drives the electric gripper 56 and the packaging bag and drags the packaging bag horizontally above the centering mechanism 5. The multiple sets of electric push rods 26 fixed on the guide rod 25 move synchronously, driving the centering bracket 27 to pass through the clearance hole 2 to center and position the packaging bag from both sides. After positioning, the electric push rod 9 on the bag feeding frame 11 is activated. The telescopic end of the electric push rod nine drives the bag feeding roller to press down, so that the bag feeding roller contacts the packaging bag. With the help of friction, the packaging bag is conveyed forward along the guide plate 51 of the bag opening mechanism. After reaching the bag opening position, the bag opening suction cups 48 connected to the vacuum pump through the multi-way valve on the bag opening frame one 54 and bag opening frame two 55 respectively adsorb the upper and lower sides of the bag opening. Then, the electric push rod eight 49 retracts, pulling the bag opening frame one 54 up to open the bag opening. Immediately afterwards, the output shaft of the drive motor two of the inserting knife mechanism drives the rotating shaft one 43, so that the opening inserting knife 44 on the inserting knife frame and the clamping rod 45 on the clamping plate frame swing down and insert into the bag opening. The electric push rod seven 46 moves to adjust the angle of the opening inserting knife 44. At the same time, the half gear ends of the two gear clamping plates at the end of the clamping rod 45 mesh and rotate, driving the clamping plate ends to move towards each other, thereby clamping the front and rear sides of the packaging bag. Finally, the output shaft of the drive motor two drives the rotating shaft one 43 to rotate, dragging the packaging bag to the bottom of the quantitative feeding mechanism 52. After the packaging bag is in place, the electric push rod 10 and electric push rod 18 on both sides of the filling nozzle 19 of the quantitative feeding mechanism 52 work together to drive the duckbill plate and the clamping top plate 53 to clamp the bag mouth from the inside and outside. At the same time, the supporting mechanism 4 starts to work: during filling, the vibrating seat 35 supports the bottom of the bag, and in the clamping components 31 on both sides, the electric push rod 32 drives the clamping rod 33 to fall and clamp the bag body from the side. This action is linked by the connecting rod 14, the connecting rod 3 and the connecting piece 39. At the same time, the electric push rod 11 drives the rotating plate to rotate, and through the transmission of the connecting rod 4, the arc-shaped clamping plate 36 clamps the bag body from the rear. After the packaging bag is stabilized in multiple directions, the material accurately measured by the quantitative feeding hopper 17 is poured into the bag through the filling nozzle 19. At the same time, the vibrating seat 35 starts to vibrate, so that the material is densely filled in the bag. After filling and compaction, the telescopic end of the electric push rod 40 drives the support plate to move horizontally, transferring the fully loaded packaging bag to the bottom of the shaping and sewing mechanism 2. The drive motor 13 of the shaping and sewing mechanism 2 starts, driving two left and right symmetrical belt conveyors 15 to rotate synchronously in opposite directions through the gear pair, clamping and sorting the bag opening. During this process, the sewing machine 16 completes the sewing of the bag opening. After the sewing is completed, the bagged rice is conveyed to the conveying mechanism 3, and finally the conveying mechanism 3 outputs the finished product, completing the entire automated packaging process.
[0066] In summary, through the automatic pushing of bag stacks by the bag feeding mechanism 7, the precise bag picking by the bag picking mechanism 8, the horizontal transfer by the clamping and dragging mechanism 6, the centering and positioning by the centering mechanism 5, and the coordinated conveying of the electric push rod nine and the bag feeding rollers by the bag feeding frame 11, the packaging bags are automatically, continuously transferred and positioned from the stack to the bag opening station, thereby improving the efficiency and reliability of the bag feeding and bag loading process. The bag opening mechanism achieves stable adsorption and opening of the bag opening, the inserting mechanism inserts, expands and firmly clamps the bag opening, and delivers the bag to the filling position; the quantitative feeding mechanism 52 clamps the bag opening and performs quantitative filling at the filling nozzle 19; the supporting mechanism 4 supports the bag body from the bottom, clamps it from the side and holds it from the rear during the filling and compaction process to prevent tipping and ensure the dense filling of the material, thus ensuring stable filling operation. The shaping and sewing mechanism 2 completes the sorting and flattening, and works with the sewing machine 16 to achieve stable sewing. Finally, the finished product is automatically output through the conveying mechanism 3. All mechanisms are highly integrated based on the packaging frame 10 and are linked in an orderly manner through electrical and pneumatic control to form a highly efficient, continuous, and automated rice bagging and packaging device, which reduces labor costs and labor intensity, and ensures the consistency of packaging quality.
