Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging machines, and in particular to a vibratory rice shaping vacuum packaging machine. Background Technology

[0002] Rice is one of the staple foods for humans. Inadequate packaging can make rice susceptible to moisture and mold. Prolonged contact with air, including moisture and oxygen, can easily cause rice to spoil. To prevent moisture and mold growth and improve preservation, a vibratory shaping vacuum packaging machine is typically used to reshape the rice before vacuum packaging. This process not only vacuum-packs the rice but also reshapes it during packaging, ensuring the rice is evenly distributed within the vacuum bag.

[0003] When using a vibratory shaping vacuum packaging machine, a vacuum bag containing rice is placed in the vacuum chamber. A pressure strip pre-compresses and positions the bag opening, then the vacuum lid is closed, followed by vacuuming and shaping to achieve vacuum packaging. However, in this type of vacuum packaging machine, the vacuum lid is simply sealed with a rubber strip, resulting in a mediocre seal and a tendency for incomplete vacuuming, thus affecting the overall vacuum packaging effect. Furthermore, the silicone strip on the vacuum lid that compresses and secures the bag is a single, integral structure and cannot self-adjust. When the bag opening is uneven or wrinkled, excessive local pressure can occur, affecting the overall compression effect. Utility Model Content

[0004] The main purpose of this invention is to provide a vibratory rice shaping vacuum packaging machine, which can effectively solve the problems in the background art.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-4 As shown, a vibratory rice shaping vacuum packaging machine includes a device body 1, a vibratory plate 2 inside the device body 1, a vacuum cover 3 on the device body 1, a sealing groove 4 and a trapezoidal groove 5 on the device body 1, a sealing rod 6 inside the device body 1, a pressure strip 7 inside the device body 1, a sealing component 9 installed on the vacuum cover 3, and a pressing component 10 on the vacuum cover 3.

[0016] The main body 1 of the device is equipped with a moving cylinder 8 inside, and the telescopic shaft of the moving cylinder 8 is connected to the sealing rod 6. The main body 1 of the device is equipped with a tilting cylinder 11 on the outside, and the upper end of the tilting cylinder 11 is rotatably connected to the vacuum cover 3. The main body 1 of the device is equipped with a controller 12 at the front end.

[0017] When using a vibratory shaping vacuum packaging machine to package rice, after connecting the pipeline and ventilating, the flipping cylinder 11 on the main body 1 drives the vacuum cover 3 to flip open. The packaging bag containing rice is placed flat on the vibratory plate 2, and the bag opening is placed on the sealing rod 6. The flipping pressure strip 7 pre-fixes the bag opening. Then, after starting the flipping cylinder 11, the vacuum cover 3 flips down onto the main body 1. The sealing component 9 is inserted into the sealing groove 4 and the trapezoidal groove 5. The components in the sealing component 9 are inflated to ensure the sealing performance of the vacuum cover 3 after it is closed. At the same time, the pressing component 10 presses and fixes the bag opening of the vacuum bag. After the device is started by controller 12, vacuuming begins. After vacuuming, the sealing rod 6 performs instant heat sealing. After sealing, the moving cylinder 8 moves through the sealing rod 6, carrying the rice bag back to the middle of the vibrating plate 2. Since the inside of the main body 1 is under negative pressure at this time, the packaging bag will expand and bulge. The vibrating plate 2 starts to vibrate and shape the rice. After shaping, air is injected into the main body 1, and the air pressure inside the main body 1 increases and recovers. Under the action of air pressure, the packaging bag shrinks back and wraps around the shaped rice. Then, the vacuum cover 3 is opened and the rice is taken out.

[0018] According to the above implementation scheme, the sealing component 9 includes a rubber strip 901, an airbag 902 and an air tube 903. The rubber strip 901 is fixed on the vacuum cover 3, the airbag 902 is connected to the rubber strip 901, and the air tube 903 is connected to the airbag 902 and passes through the rubber strip 901 and the vacuum cover 3.

[0019] When the vacuum cover 3 is closed, the rubber strip 901 is inserted into the sealing groove 4, and the airbag 902 is inserted into the trapezoidal groove 5. The gas source provides gas to inflate the airbag 902 through the air pipe 903. The airbag 902 expands and fills the trapezoidal groove 5, thereby forming an effective seal. Together with the sealing effect of the rubber strip 901, the connection and sealing of the vacuum cover 3 can be ensured. Then, the shaping and vacuum packaging operation can be carried out. After the packaging is completed, the air is evacuated through the air pipe 903, the airbag 902 shrinks and recovers, and then the vacuum cover 3 can be opened.

[0020] According to the above implementation scheme, the clamping assembly 10 includes a fixed plate 1001, a mounting block 1002, a pressure plate 1003, a silicone strip 1004, a movable rod 1005, a spring 1006, a stud 1007, and an adjusting plate 1008. The fixed plate 1001 and the mounting block 1002 are fixedly connected, and the upper end of the mounting block 1002 is connected to the vacuum cover 3. The pressure plate 1003 is fixedly connected to the silicone strip 1004 and the movable rod 1005. The spring 1006 is sleeved on the movable rod 1005 and is located between the fixed plate 1001 and the pressure plate 1003. The stud 1007 is set on the movable rod 1005, and the structure formed by the movable rod 1005 and the stud 1007 passes through the fixed plate 1001. The adjusting plate 1008 is threadedly connected to the stud 1007.

[0021] When the vacuum cover 3 is closed, the silicone strip 1004 at the lower end of the pressure plate 1003 presses against the opening of the packaging bag. During this process, the pressure plate 1003 moves via the movable rod 1005 and compresses the spring 1006. After compression, the spring 1006 acts as an adaptive elastic clamping fixation, ensuring uniform compression. After compression, the shaping vacuum packaging process is performed. When needed, the adjusting plate 1008 can be rotated, causing the stud 1007 to move relative to the fixed plate 1001, thereby moving the pressure plate 1003 and silicone strip 1004 relative to the fixed plate 1001. This allows for adjustment of the position of the pressure plate 1003, improving its flexibility and adaptability.

[0022] It should be noted that by opening a sealing groove 4 and a trapezoidal groove 5 on the main body 1 of the device, and using it in conjunction with the sealing component 9, after the vacuum cover 3 is closed, air is injected into the air bag 902 through the air pipe 903. The expansion of the air bag 902 is used for sealing. Combined with the sealing groove 4 and the rubber strip 901, the sealing performance of the vacuum cover 3 after closing can be ensured, thus guaranteeing the subsequent vacuum packaging effect. The pressing component 10 is used, which sets the pressure plate 1003 and the silicone strip 1004 in segments. Combined with the movable rod 1005 and the spring 1006, it can form an adaptive elastic pressing when pressing the bag opening. It can automatically adjust the position according to the local pressure to ensure the uniformity of the overall pressing. The relative position of the pressure plate 1003 can be adjusted by using the stud 1007 and the adjusting plate 1008, which is convenient for adjustment and highly flexible.

[0023] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
