Description

Technical Field

[0001] The utility model relates to the technical field of sealing and packaging machines, in particular to an automatic sealing and packaging machine for rice noodles. Background Art

[0002] After processing, the rice noodles need to be put into a packaging bag, and then the opening of the packaging bag is sealed to form bagged rice noodles, thereby completing the sealed packaging of the rice noodles. During the sealing and packaging process of the bagged rice noodles, the air in the packaging bag needs to be extracted to make the packaging bag shrink inward, so that the volume of the bagged rice noodles is reduced, which is convenient for transportation and increases the shelf life of the rice noodles.

[0003] The Chinese utility model patent with announcement number CN220181261U discloses a hot-pressing sealing device for rice noodle packaging bags, including a base plate, an air extrusion assembly arranged on an L-shaped bracket, and a hot-pressing sealing assembly arranged on the L-shaped bracket, a bevel gear 1 fixedly connected to the end of the double-axis motor rotor, a turntable rotatably connected to the L-shaped bracket through a rotating shaft, a bevel gear 2 fixedly connected to the rotating shaft and meshingly connected to the bevel gear 1, a rectangular frame movably connected to a column, a piston plate movably connected to the inside of an exhaust chamber, a placement chamber fixedly mounted on the top of the base plate, an air bag arranged inside the placement chamber, and a connecting pipe for connecting the exhaust chamber and the air bag. The air extrusion assembly is effectively avoided because of the lack of an integrated air extrusion structure, so that air remains in the sealed packaging bag, thereby accelerating the deterioration of food and shortening the storage time of food.

The sealing device comprises a sealing drive 51 and an electric heating plate 52 . The sealing drive 51 is mounted on the connecting frame 31 , and the electric heating plate 52 is mounted at the output end of the sealing drive 51 . The sealing drive 51 is a cylinder.

[0037] The clamping plate 32 is provided with a clamping groove 34 cooperating with the material blocking tube 41 , and the clamping plate 32 is slidably connected with a movable plate 35 located at the clamping groove 34 , and a clamping elastic member 36 is provided between the movable plate 35 and the clamping plate 32 , and the clamping elastic member 36 is a spring.

[0038] The air extraction pipe 23 is provided with an air inlet groove 24, which extends along the length direction of the air extraction pipe 23. The air inlet groove 24 extends to one end of the air extraction pipe 23 close to the conveying device 11. The width of the cross section of the air inlet groove 24 gradually increases along the direction close to the outer wall of the air extraction pipe 23. The material blocking pipe 41 is fixedly connected with a material blocking block 42 that cooperates with the air inlet groove 24.

[0039] An air extraction drive 25 is provided between the air extraction workbench 12 and the sliding seat 21. The air extraction drive 25 is a cylinder. Both ends of the air extraction drive 25 are connected to the air extraction workbench 12 and the sliding seat 21, respectively. The sliding seat 21 is fixedly connected with a push block 43. The material blocking tube 41 is fixedly connected with a push frame 44. The side of the push block 43 away from the air extraction tube 23 is clamped with the push frame 44. The push frame 44 is provided with a movable groove 45 for the push block 43 to move. A material blocking elastic member 46 is provided between the material blocking tube 41 and the air extraction workbench 12. The material blocking elastic member 46 is a spring.

[0040] After the rice noodles are loaded into the packaging bag at the filling workbench 13, the conveying device 11 conveys the packaging bag containing the rice noodles to the suction device, and the clamping drive 33 drives the clamping plate 32 and the suction nozzle 26 to move toward the packaging bag, so that the suction nozzle 26 connected to the external negative pressure device sucks the outer wall of the packaging bag, and then the clamping drive 33 drives the clamping plate 32 and the suction nozzle 26 to move toward the outside of the packaging bag to open the opening of the packaging bag. Then the suction drive 25 drives the sliding seat 21 and the suction pipe 23 to move, so that the suction pipe 23 is inserted into the opening of the packaging bag, and the material blocking pipe 41 moves between the two clamping plates 32 under the elastic force of the material blocking elastic member 46, and the limit block 47 is clamped with the suction workbench 12. The clamping drive 33 drives the two clamping plates 32 to approach each other and clamp the packaging bag, and the air in the packaging bag is extracted through the suction pipe 23 connected to the external negative pressure device. After the air in the packaging bag is extracted, the suction drive 25 drives the suction pipe 23 to move outside the packaging bag. At this time, the blocking block 42 moves relative to the suction pipe 23 and pushes out the rice noodles in the air inlet groove 24 through the blocking block 42. The end of the suction pipe 23 close to the inner side of the packaging bag moves to the blocking plate, and the push block 43 is engaged with the push frame 44, so that the sliding seat 21 drives the blocking pipe 41 and the suction pipe 23 to move synchronously to the side away from the packaging bag through the push block 43 and the push frame 44. In the process of the blocking pipe 41 sliding out of the packaging bag opening, the two movable plates 35 move toward the packaging bag under the elastic force of the clamping elastic member 36 and clamp the packaging bag at the clamping groove 34 to prevent the rice noodles from leaking out from the clamping groove 34 after the blocking pipe 41 is extracted. Then the sealing drive 51 drives the two electric heating plates 52 to clamp the packaging bag, so that the packaging bag is thermoplastically sealed. Then, the clamping drive 33 and the sealing drive 51 drive the clamping plate 32 and the electric heating plate 52 respectively to loosen the packaging bag, so that the conveying device 11 can convey the sealed packaging bag to the outside of the equipment.

[0041] This embodiment has the following advantages:

[0042] After the exhaust pipe 23 extracts the air in the packaging bag, the driving device drives the sliding seat 21 and the exhaust pipe 23 to move away from the packaging bag. In this process, the material blocking tube 41 is set to block the rice noodles driven by the exhaust pipe 23, preventing the rice noodles from moving to the electric heating plate 52 with the exhaust pipe 23, preventing air leaks and loose seals in the packaging bag, thereby improving the reliability of the seal and achieving the advantage of higher reliability in the continuous production process.

[0043] The clamping groove 34 cooperates with the material blocking tube 41 to improve the sealing performance of the clamping plate 32 during the process of the exhaust pipe 23 extracting the air in the packaging bag, thereby improving the exhaust efficiency and preventing air backflow. The clamping elastic member 36 drives the movable plate 35 to clamp the packaging bag at the clamping groove 34 to prevent the rice noodles from accidentally leaking from the clamping groove 34 to the opening of the packaging bag after the material blocking tube 41 is extracted, thereby ensuring the sealing performance during sealing and achieving the advantage of higher reliability in the continuous production process.

[0044] The air inlet groove 24 extends along the length direction of the air extraction pipe 23, so that the air inlet groove 24 is relatively long, thereby preventing the air inlet groove 24 from being completely blocked by rice noodles, ensuring that the air extraction pipe 23 can extract the air in the packaging bag, and improving reliability.

[0045] When the air extraction pipe 23 moves away from the packaging bag, the blocking block 42 can push the rice noodles in the air inlet groove 24 to the outside of the air inlet groove 24, preventing the rice noodles from moving to the opening of the packaging bag along with the air extraction pipe 23, thereby ensuring the sealing performance during sealing and achieving the advantage of high reliability in the continuous production process. At the same time, the air inlet groove 24 can be blocked during the continuous circulation of the air extraction pipe 23, thereby playing the function of cleaning the air inlet groove 24.

[0046] One end of the air inlet groove 24 close to the inner wall of the air extraction pipe 23 has a smaller width to prevent rice noodles from entering the air extraction pipe 23; one end of the air inlet groove 24 close to the outer wall of the air extraction pipe 23 has a larger width to prevent the air inlet pipe from being blocked by rice noodles.

[0047] During the process of the vacuum pipe 23 drawing out the packaging bag, the push block 43 moves in the movable groove 45. When the vacuum pipe 23 moves to the blocking block 42 at one end close to the packaging bag, the push block 43 is engaged with the push frame 44, so that the sliding seat 21 can drive the blocking pipe 41 to move through the push block 43 and the push frame 44, so that the blocking pipe 41 can draw out the packaging bag along with the vacuum pipe 23, thereby realizing the function of driving the blocking pipe 41 to slide out of the packaging bag.

[0048] The limiting block 47 is engaged with the workbench to limit the material blocking tube 41 , thereby preventing the material blocking tube 41 from entering too deeply into the packaging bag and blocking the air inlet groove 24 .

[0049] The sealing drive 51 drives the electric heating plate 52 to move toward the packaging bag, so that the electric heating plate 52 contacts the packaging bag. The electric heating plate 52 heats the packaging bag to increase the temperature at the opening of the packaging bag, thereby realizing the function of thermoplastic sealing the packaging bag through the sealing device.

[0050] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
