[0002] The carbohydrates in rice are mainly starch, and the proteins it contains are mainly rice glutenin, followed by rice glutenin and globulin.

[0003] The utility model patent with authorization announcement number CN215044020U discloses a rice vacuum packaging device, which solves the problem that in the process of using general rice vacuum packaging devices, it is necessary to manually smooth out the wrinkles of rice packaging bags, which increases the labor intensity of workers.

[0004] In the aforementioned patent, when using a suction tube for vacuuming, it is difficult to ensure the seal between the suction tube and the bag opening. Consequently, it is difficult to remove the air from the inner wall of the rice packaging bag during the vacuuming process, affecting the quality of the rice packaging. To solve the above problems, we propose a rice vacuum packaging device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vacuum packaging device for rice.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rice vacuum packaging device includes a packaging platform. A rice packaging sealing assembly and a vacuum packaging assembly are sequentially arranged on the upper side of the packaging platform. The rice packaging sealing assembly includes a placement groove with sliding grooves on both sides. A heating plate is symmetrically slidably installed inside the sliding grooves. A fixing block is located in the middle of the heating plate. A semi-circular groove is formed inside the fixing block, and a concave sliding groove is formed inside the semi-circular groove. A sliding plate is slidably installed inside the concave sliding groove. A heating wire is embedded inside the sliding plate. A second synchronous electric push rod is fixedly installed behind the fixing block, and the output end of the second synchronous electric push rod is fixedly connected to the sliding plate.

[0008] Furthermore, mounting plates are symmetrically fixedly installed on both sides of the placement slot, and a first synchronous electric push rod is fixedly installed between the mounting plates and the heating plate.

[0009] By adopting the above technical solution, the first synchronous electric push rod can push the heating plates on both sides closer to each other, thereby pressing the bag opening of the packaging bag against the inside of the heating plates on both sides for heat fusion sealing.

[0010] Furthermore, a heat insulation plate is fixedly connected between the fixing block and the heating plate.

[0011] Furthermore, the vacuum packaging assembly includes a structural frame groove, a vacuum pump is fixedly installed inside the structural frame groove, an air suction pipe is fixedly installed at the bottom of the structural frame groove, the air suction pipe is connected to the suction end of the vacuum pump, and a rubber sleeve is fitted on the outer wall of the lower end of the air suction pipe.

[0012] By adopting the above technical solution, the rubber sleeve ensures that when the suction tube is inserted into the inside of the bag opening, the outer wall of the suction tube and the bag opening remain sealed, thus facilitating subsequent vacuuming work.

[0013] Furthermore, the outer diameter of the rubber sleeve is slightly larger than the inner diameter of the semi-circular groove, and a metal filter screen is fixedly installed at the lower end of the suction pipe.

[0014] Furthermore, an outlet pipe is fixedly connected to the upper side of the vacuum pump, and a flow meter is fixedly installed on the outer wall of the outlet pipe.

[0015] By adopting the above technical solution, the flow meter is used to monitor the air output of the air outlet pipe and to determine the air evacuation status inside the packaging bag.

[0016] Furthermore, several side ribs are fixedly connected between the outer wall of the air intake pipe and the bottom of the structural frame groove.

[0017] Furthermore, the rubber sleeve is made of silicone rubber.

[0018] By adopting the above technical solution, the silicone rubber material has high temperature resistance, avoiding the heating effect of the side heating plate.

[0019] Furthermore, a support frame is fixedly installed on the upper side of the packaging table, and a controller is fixedly installed on the side wall of the support frame.

[0020] Furthermore, an electric telescopic rod is fixedly installed on the bottom of the upper side of the support frame, and the output end of the electric telescopic rod is fixedly connected to the upper side of the structural frame groove.

[0021] By adopting the above technical solution, when the electric telescopic rod is started, it can drive the entire vacuum packaging assembly to move up and down, thereby driving the suction tube to be inserted into the inside of the packaging bag.

[0022] Compared with related technologies, the rice vacuum packaging device proposed in this utility model has the following beneficial effects:

[0023] In this utility model, a rice vacuum packaging device is provided. The rice packaging sealing assembly has heating plates on both sides that clamp and heat-seal the bag opening. A fixing block with a semi-circular groove is located in the middle of the heating plates. When the heating plates are closed, a groove matching the suction pipe is formed in the middle. Before the heating plates close, the suction pipe descends to the middle position between the two semi-circular grooves. After closing, the bag opening is tightly abutted against the outer wall of the suction pipe by the groove, keeping the suction area sealed. This facilitates subsequent vacuuming, improves the vacuuming effect, and enhances the packaging quality of the rice. Furthermore, a sliding groove is provided inside the semi-circular groove of the fixing block, and a sliding plate with an embedded heating wire is provided inside the sliding groove. After vacuuming, sliding out the sliding plate completes the sealing of the suction area, ensuring the integrity of the bag opening seal. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figures 1-5 A rice vacuum packaging device includes a packaging platform 1, on which a rice packaging sealing assembly 5 and a vacuum packaging assembly 6 are sequentially arranged. The rice packaging sealing assembly 5 includes a placement groove 51, with sliding grooves 52 on both sides of the placement groove 51. A heating plate 53 is symmetrically slidably installed inside the sliding groove 52. A fixing block 56 is provided in the middle of the heating plate 53. A semi-circular groove 59 is provided inside the fixing block 56. A concave sliding groove 510 is provided inside the semi-circular groove 59. A sliding plate 511 is slidably installed inside the concave sliding groove 510. A heating wire 512 is embedded inside the sliding plate 511. A second synchronous electric push rod 58 is fixedly installed on the rear side of the fixing block 56. The output end of the second synchronous electric push rod 58 is fixedly connected to the sliding plate 511.

[0032] In this embodiment, a support frame 2 is fixedly installed on the upper side of the packing table 1, a controller 3 is fixedly installed on the side wall of the support frame 2, and an electric telescopic rod 4 is fixedly installed at the bottom of the upper side of the support frame 2. The output end of the electric telescopic rod 4 is fixedly connected to the upper side of the structural frame groove 61.

[0033] With the above structure, the electric telescopic rod 4 can drive the structural frame groove 61 to move up and down.

[0034] In this embodiment, mounting plates 54 are symmetrically fixedly installed on both sides of the placement groove 51, and a first synchronous electric push rod 55 is fixedly installed between the mounting plates 54 and the heating plate 53.

[0035] With the above structure, when the first synchronous electric push rod 55 starts synchronously, it can drive the heating plates 53 to move closer to each other, so as to perform heat sealing work on the opening of the packaging bag.

[0036] In this embodiment, a heat insulation plate 57 is fixedly connected between the fixing block 56 and the heating plate 53.

[0037] With the above structure, the heat insulation plate 57 allows the heating plate 53 to perform heat-sealing on the bag opening areas on both sides of the fixing block 56. Its heating temperature will not interfere with the circular groove inside the fixing block 56, so that the area inside the semi-circular groove of the suction pipe 65 will not be heat-sealed before the suction is completed. This makes it easier for the suction pipe 65 to be pulled out of the bag opening. After the suction pipe 65 is pulled out, the second synchronous electric push rod 58 and the heating wire 512 are quickly activated, so that the heated sliding plates 511 on both sides seal the bag opening inside the semi-circular groove 59, completing the sealing and sealing of the suction point and ensuring the integrity of the packaging bag.

[0038] In this embodiment, the vacuum packaging assembly 6 includes a structural frame groove 61, a vacuum pump 62 is fixedly installed inside the structural frame groove 61, a suction pipe 65 is fixedly installed at the bottom of the structural frame groove 61, the suction pipe 65 is connected to the suction end of the vacuum pump 62, a rubber sleeve 67 is fitted on the outer wall of the lower end of the suction pipe 65, the outer diameter of the rubber sleeve 67 is slightly larger than the inner diameter of the semi-circular groove 59, and a metal filter screen 68 is fixedly installed at the lower end of the suction pipe 65.

[0039] With the above structure, the vacuum pump 62 is started to draw air out, and the air inside the packaging bag is discharged through the suction pipe 65, the working chamber of the vacuum pump 62 and the exhaust pipe 63. The metal filter 68 is set to prevent rice from being drawn into the vacuum pump 62 and to provide protection for the vacuum pump 62.

[0040] In this embodiment, an outlet pipe 63 is fixedly connected to the upper side of the vacuum pump 62, and a flow meter 64 is fixedly installed on the outer wall of the outlet pipe 63.

[0041] With the above structure, the flow meter 64 is used to monitor the air flow rate in the exhaust pipe 63. When the air flow rate in the exhaust pipe 63 approaches zero, it indicates that the vacuum suction operation is completed.

[0042] In this embodiment, a number of side ribs 66 are fixedly connected between the outer wall of the air intake pipe 65 and the bottom of the structural frame groove 61.

[0043] The structure described above, including the side rib plate 66, improves the structural installation strength of the intake pipe 65.

[0044] In this embodiment, the rubber sleeve 67 is made of silicone rubber.

[0045] Through the above structure, the silicone rubber material has high temperature resistance, which enables the rubber sleeve 67 to maintain its sealing performance when subjected to high temperatures.

[0046] In this utility model, the working process is as follows:

[0047] Air suction pipe positioning: The electric telescopic rod 4 on the support frame 2 is activated by the controller 3. The output end of the electric telescopic rod 4 extends, which drives the structural frame groove 61 in the vacuum packaging assembly 6 to move downward, so that the air suction pipe 65 is lowered to the middle position between the two semi-circular grooves 59. The rubber sleeve 67 fitted on the lower outer wall of the air suction pipe 65 has an outer diameter that is slightly larger than the inner diameter of the semi-circular groove 59, to ensure that it can be tightly abutted against the opening of the packaging bag and to ensure the airtightness of the suction point.

[0048] Pre-sealing of the bag opening: The first synchronous electric push rod 55 between the folding plate 54 and the heating plate 53 installed on both sides of the placement slot 51 is activated. The first synchronous electric push rod 55 pushes the heating plates 53 on both sides to move closer together, pressing the bag opening of the packaging bag against the inner side of the heating plates 53 on both sides. At this time, the heating plates 53 heat-seal the bag opening. Since there is a heat insulation plate 57 connecting the fixing block 56 and the heating plate 53, the heating temperature of the heating plate 53 will not interfere with the semi-circular groove 59 on the inner side of the fixing block 56. This ensures that the area inside the semi-circular groove 59 will not heat-seal before the air extraction is completed, making it convenient for the suction pipe 65 to be pulled out from the bag opening later. During the closing process of the heating plates 53 on both sides, the semi-circular groove 59 on the inner side of the fixing block 56 forms a circular groove in the middle position that matches the suction pipe 65. After the packaging bag opening is closed, the circular groove abuts against the outer wall of the suction pipe 65.

[0049] Vacuuming Operation: After the bag opening is pre-sealed and tightly abuts against the suction pipe 65, the vacuum pump 62 inside the structural frame groove 61 is activated. The vacuum pump 62 extracts air from the inside of the packaging bag through the suction pipe 65. The air passes sequentially through the suction pipe 65, the working chamber of the vacuum pump 62, and the exhaust pipe 63 before being discharged. The metal filter 68 at the lower end of the suction pipe 65 effectively prevents rice from being sucked into the vacuum pump 62, thus protecting the vacuum pump 62. Simultaneously, the flow meter 64 on the outer wall of the exhaust pipe 63 monitors the air velocity in the exhaust pipe 63 in real time. When the flow meter 64 shows that the air velocity in the exhaust pipe 63 approaches zero, it indicates that the air inside the packaging bag has been basically evacuated, and the vacuuming operation is complete.

[0050] Sealing at the vacuum extraction point: After the vacuum extraction is completed, the electric telescopic rod 4 drives the vacuum packaging assembly 6 to rise, causing the suction pipe 65 to be pulled out from the bag opening. At this time, the second synchronous electric push rod 58 on the rear side of the fixing block 56 is quickly activated. The second synchronous electric push rod 58 pushes the slide plate 511 to slide out from the concave groove 510. At the same time, the heating wire 512 embedded in the slide plate 511 is activated, so that the heated slide plate 511 on both sides seals the bag opening in the inner area of ​​the semi-circular groove 59, completing the sealing of the vacuum extraction point, ensuring the integrity of the packaging bag, and finally completing the vacuum packaging of rice.
