Description

Technical Field

[0001] This utility model relates to the field of rice processing equipment, specifically to a novel rice sealing and packaging mechanism. Background Technology

[0002] After rice is hulled, it needs to be packaged. High-end rice is generally packaged using negative pressure, forming a brick-like shape for easy stacking and transportation. The current method of sealing rice involves placing a bag into a rectangular mold, filling the bag with rice, and then placing the mold and bag into a negative pressure space. This vacuums the bag and heat-seals it within the negative pressure cavity. However, this packaging process still requires manual placement of the bag into the sealed space, resulting in low packaging efficiency and making continuous packaging impossible. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model proposes a novel rice sealing packaging mechanism that facilitates continuous rice packaging without manual operation, thereby improving packaging efficiency.

[0004] To achieve the above objectives, the present invention provides a novel rice sealing packaging mechanism, comprising a conveyor chain, a forming mold, a bagging mechanism, and a negative pressure mechanism. Multiple mounting plates arranged side-by-side are mounted on the conveyor chain, and a vertical forming mold is mounted on each mounting plate. The forming mold has an opening at the top. A negative pressure mechanism is located above the conveyor chain. The mounting plates are mounted on the conveyor chain via telescopic components, which allow the mounting plates to rise and fall. A filling component is located above the mounting plates to fill the rice. A bagging mechanism is located below the filling component to place the bag onto the filling component.

[0005] The negative pressure mechanism is a negative pressure chamber with an open bottom. A sealing component is installed at the top inside the negative pressure chamber, and a lifting component is installed below the negative pressure chamber. The mounting plate is raised by the lifting component, and the mounting plate closes the bottom of the negative pressure chamber by lifting and lowering. In this way, a negative pressure area is formed inside the negative pressure chamber by drawing a vacuum.

One end of the swing arm is rotatably connected to the outer wall of the molding box. The swing clamp is installed on the swing arm. When the swing arm closes, the swing clamp clamp clamps the bag opening. A negative pressure hole is provided at the bottom of the molding box, which is connected to a negative pressure pump to adsorb the bottom of the bag. Gears are fixed at the rotatable connection between the two swing arms on the same side and the molding box. A rack that meshes with the two gears is inserted between the two gears. The rack slides against the outer wall of the molding box. A trigger rod is fixed at the top of the rack. A spring is provided between the trigger rod and the molding box to lift the trigger rod upward.

[0007] Preferably, connectors are fixed on both sides of the bottom of the molding box, and the connectors are connected to the negative pressure holes. Telescopic plates are provided on both sides below the filling component, and through holes are opened on the end face of the telescopic plates facing the molding box for the connectors to extend into, and the through holes are connected to the negative pressure pump.

[0008] Preferably, the bagging mechanism includes a conveyor chain, a bag opening plate, and a negative pressure suction head. The conveyor chain consists of two parallel conveyor chains. Multiple bag opening plates are installed on each conveyor chain. A negative pressure suction head is installed on the opposite face of each bag opening plate.

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] like Figure 1-7As shown, a novel rice sealing packaging mechanism includes a conveyor chain 1, a forming mold 2, a bagging mechanism 24, and a negative pressure mechanism 14. The conveyor chain 1 consists of two parallel conveyor chains 1, each mounted on two conveyor chain wheels 25. The center of the outer end face of each conveyor chain wheel 25 is welded to the output shaft of a motor. The motor drives the conveyor chain wheels 25 to rotate, which in turn drives the conveyor chain 1. Multiple mounting plates 16 are mounted side-by-side on the conveyor chain 1. The bottom of each mounting plate 16 rests on the conveyor chain 1, and a sleeve is welded to the conveyor chain 1. A column is fixed to the bottom of each mounting plate 16, passing through the sleeve for lifting and lowering. A vertical forming mold 2 is mounted on the top of each mounting plate 16. The forming mold 2 is a rectangular box with an open top. The negative pressure mechanism 14 is positioned above the conveyor chain 1. The mounting plates 16 are mounted on the conveyor chain 1 via telescopic components 19, which also serve as the columns. The mounting plate 16 is raised and lowered via the telescopic component 19. When a bag is placed inside the forming mold 2 and filled with rice, the mounting plate 16 is lifted upwards, so that the top of the mounting plate 16 fits tightly against the bottom of the negative pressure mechanism 14. The mounting plate 16 extends into the negative pressure mechanism 14 through the forming mold 2. To ensure a tight seal, the bottom of the negative pressure mechanism 14 is covered with sealing rubber. When the negative pressure mechanism 14 is under negative pressure, the bag is sealed inside the negative pressure mechanism 14, and the bag is also under negative pressure. In this configuration, a filling assembly 20 is provided above the mounting plate 16. The filling assembly 20 is located to the left of the negative pressure mechanism 14. The filling assembly 20 is used to fill rice into the negative pressure seal. A bagging mechanism 24 is provided below the filling assembly 20. The bagging mechanism 24 transports the bag body located on the left side to the bottom of the filling assembly 20. The filling assembly 20 descends, the bag body is placed on the filling assembly 20, the filling assembly 20 descends and is inserted into the forming mold 2, so that the bag body is also embedded in the forming mold 2.

[0021] The negative pressure mechanism 14 is a negative pressure chamber 15 with an open bottom. The outer wall of the negative pressure chamber 15 is mounted on the frame via a support column. The bottom of the frame is placed on the ground via support legs. The conveyor chain 25 is mounted on the frame via bearings. The negative pressure chamber 15 is a rectangular box. A vacuum pump for vacuuming is installed at the top of the negative pressure chamber 15. The vacuum pump is connected to the inside of the negative pressure chamber 15 via a pipe. The bottom of the negative pressure chamber 15 has a cavity for the molding mold 2 to extend into. The bottom of the negative pressure chamber 15 is covered with sealing rubber with glue. When the mounting plate 16 rises, the top of the mounting plate 16 presses against the sealing rubber to seal. A sealing assembly 17, which is a heat sealing strip, is provided at the top inside the negative pressure chamber 15. The heat sealing strip consists of two... The two heat-sealing strips are arranged opposite each other. When the mounting plate 16 rises and the forming mold 2 is located between the two heat-sealing strips, each heat-sealing strip is fixed to the inner wall of the negative pressure chamber 15 by bolts with a cylinder. The cylinders lift the heat-sealing strips to close them, thus heat-sealing the bag opening. After heat-sealing, the mounting plate 16 descends. A lifting assembly 18 is set directly below the negative pressure chamber 15. The bottom of the lifting assembly 18 is fixed to the frame by bolts. The lifting assembly 18 can extend and retract. The lifting assembly 18 pushes the bottom of the mounting plate 16, thus raising the mounting plate 16. The mounting plate 16 closes the bottom of the negative pressure chamber 15 by lifting and lowering, thus creating a negative pressure area inside the negative pressure chamber 15 by vacuuming.

[0022] The molding die 2 includes a molding box 3 and a swing clamping plate 4. Swing arms 5 are installed on the left and right sides of the molding box 3, with two swing arms 5 on each side. One end of the swing arm 5 is rotatably connected to the outer wall of the molding box 3. The two ends of the swing clamping plate 4 are fastened to the swing arms 5 by bolts. When the swing arms 5 close inward, the two swing clamping plates 4 swing inward to clamp the bag opening, which facilitates the sealing assembly 17 to seal. Gears 7 are fixed to the rotatable connection between the two swing arms 5 on the same side and the molding box 3 by welding. A rack 8 (with teeth on both sides) is inserted between the two gears 7 on the same side and meshes with the two gears 7 respectively. Sliding grooves are opened on the left and right outer walls of the molding box 3, and the rack 8 is fixed by welding. A slider moves up and down within a groove, thus enabling the rack 8 to move up and down. A trigger rod 9 extending upwards is fixed to the top of the rack 8 by welding. A spring that raises the trigger rod 9 is fixed between the trigger rod 9 and the forming box 3 by welding. When the mounting plate 16 is not rising, the rack 8 and the trigger rod 9 rise through the spring. This causes the rack 8 to rise, and the swing arm 5 swings outwards under the action of the gear 7. This causes the swing clamp 4 to separate. When the mounting plate 16 rises, the trigger rod 9 rests against the top of the negative pressure chamber 15. As the mounting plate 16 continues to rise, the height of the rack 8 does not change, the forming box 3 moves upwards, and the rack 8 drives the swing arm 5 to swing inwards. This causes the swing clamp 4 to clamp the bag opening, and then the heat sealing strip closes to heat seal the bag.

[0023] Multiple negative pressure holes 6 are opened at the bottom of the molding box 3. Hollow connectors 10 are fixed to both sides of the bottom of the molding box 3 by welding. The connectors 10 are connected to the negative pressure holes 6. Telescopic plates 11 are set on the front and rear sides below the filling component 20. The molding box 3 is located between two telescopic plates 11. A cylinder is fixed between the telescopic plate 11 and the frame by bolts. The telescopic plate 11 moves closer to / away from the molding box 3 by extending and retracting the cylinder. A docking point is opened on the end face of the telescopic plate 11 facing the molding box 3. The head 10 extends into the through hole 12, which is connected to the negative pressure pump through a pipe. When the filling component 20 inserts the bag into the forming box 3, the rising of the filling component 20 will also lift the bag upward. At the top of the telescopic plate 11, the connector 10 extends into the through hole 12 of the telescopic plate 11. Thus, the negative pressure hole 6 is in a negative pressure state to adsorb the bottom of the bag. In this way, when the filling component 20 rises, it will not drive the bag upward. When the filling component 20 rises completely, the telescopic plate 11 is retracted.

[0024] The bagging mechanism 24 includes a conveyor chain 25, a bag opening plate 26, and a negative pressure suction head 27. There are two conveyor chains 25 arranged side-by-side. Multiple bag opening plates 26 are installed on each conveyor chain 25, and a negative pressure suction head 27 is bolted to the opposite face of each bag opening plate 26. The negative pressure suction head 27 is connected to a negative pressure pump via a pipe, thus creating a negative pressure state that adsorbs the outer wall of the bag. The back of the bag opening plate 26... A guide rod 28 is installed by welding. A collar is fixed to the conveyor chain 25 by welding. The guide rod 28 passes through the collar and slides with the conveyor chain 25. An opening spring 29 is fitted on the guide rod 28. The opening spring 29 pulls the two bag opening plates 26 to the sides and opens them. An opening cylinder 30 is set on the outside of the guide rod 28 to move the guide rod 28 inward. The cylinder lifts and pushes the guide rod 28 inward, so that the opening plates close and the bag is attracted to a certain position. The side opening plate is sufficient; during operation, the bag body is adsorbed onto the side opening plate 26. This can be accomplished using a robotic arm (the robotic arm grips the bag close to the opening plate 26 to ensure the correct position between the opening plate 26 and the bag; currently, fixed-point feeding is done using robotic arms). When the bag body is conveyed through the opening plate to the opening cylinder 30, the opening cylinder 30 rises, the two opening plates close, and the bag body is adsorbed by the negative pressure suction heads 27 on both sides. When the bag leaves the opening cylinder 30, the opening plate moves to both sides under the action of the opening spring 29, so that the bag opens and is transported to the bottom of the filling component 20. The filling component 20 moves downward and inserts into the bag. As the filling component 20 moves downward, the bag moves downward and disengages from the negative pressure suction head 27 (the negative pressure suction head 27 mainly adsorbs the outer wall of the bag. When the filling component 20 descends, it can drive the bag to slide with the negative pressure suction head 27, which is just an increase in the distance between the bag and the negative pressure suction head 27).

[0025] The filling assembly 20 consists of a receiving hopper 21 and a feeding pipe 22. The feeding pipe 22 is fixed to the bottom of the receiving hopper 21 by welding. The feeding pipe 22 is attached to the inner wall of the bag body. The feeding hopper is fixed to the outer wall of the frame by bolts and a cylinder is fixed thereto. A support leg (not shown in the figure) is fixed to the bottom of the frame by bolts. The support leg is placed on the ground. The feeding hopper is raised and lowered by the cylinder. The feeding pipe 22 and the receiving hopper 21 are raised and lowered by the lifting assembly 23. The bottom of the feeding pipe 22 is chamfered by grinding to facilitate the insertion of the feeding pipe 22 into the bag body and the forming box 3. When the feeding pipe 22 is inserted into the forming box 3, a certain amount of rice is conveyed through the receiving hopper 21. The rice flows through the receiving hopper 21 to the feeding pipe 22 and then into the bag body of the forming box 3.

[0026] This application uses a PLC controller for operation. Multiple cylinders are connected to the air compressor via solenoid valves, which are connected to the output of the PLC controller. The PLC controller controls the extension and retraction of the cylinders. Multiple motors are connected to the output of the PLC controller via encoders. The PLC controller controls the start, stop, and speed of the motors, ensuring that the linear speed of the conveyor chain 25 and the conveyor chain 1 are consistent. The conveyor chain 1 conveys a distance equal to the distance between two mounting plates each time it starts. The power switch of the vacuum pump is connected to the output of the PLC controller, which controls the start and stop of the vacuum pump. When the motor stops working, the vacuum pump starts; before the motor starts working, the vacuum pump stops working. During filling, the mounting plate 16 of the next process is simultaneously lifted. After filling is closed, the mounting plate 16 of the next process is lowered, and the bag of the next process is sealed.
