Description

Technical Field

[0001] The present application relates to the technical field of packaging machinery, and in particular to a vacuum packaging bag flattening device. Background Art

[0002] Vacuum packaging, also known as reduced-pressure packaging, involves completely removing all air from a container and sealing it. This process maintains a highly reduced pressure within the bag. The resulting air depletion creates a hypoxic environment, making it impossible for microorganisms to survive, thus ensuring food remains fresh and free from disease and decay. This process protects products from environmental contamination, extends their shelf life, and ultimately safeguards their value and quality.

[0003] There are problems with the vacuum packaging bags produced by current vacuum packaging bag production equipment. During the vacuuming process of the packaging bags, the food in the packaging bags will pile up under the influence of gravity, and the food cannot be dispersed in the packaging bags.

[0047] The following is combined with Figures 1 to 9 This application is described in further detail.

[0048] The embodiment of the present application discloses a vacuum packaging bag flattening device.

[0049] Reference Figures 1 to 9 , a vacuum packaging bag flattening device, comprising:

[0050] Base 1, base 1 is the bottom support base of the vacuum packaging bag flattening device.

[0051] A rotating table 2 is rotatably provided on the base 1 through a slewing support, a driven gear 3 is provided on the rotating table 2, and a power unit A4 is provided on the base 1. The power unit A4 drives the driving gear engaged with the driven gear 3 to rotate. Through the setting of the power unit A4, the power unit A4 can be a motor reduction unit, which drives the rotating table 2 to rotate through gear transmission. The rotation form is simple and reliable.

[0052] Eight leveling mechanisms are distributed on the rotating table 2 at equal angular intervals along the circumference.

[0053] The leveling mechanism includes a sealing cover 5, which is buckled on the rotating table 2. The sealing cover 5 is provided with a vacuum extraction interface. The edge of the sealing cover 5 is opened in a sealing groove. A sealing ring is provided in the sealing groove. Through the setting of the sealing groove and the sealing ring, when the sealing cover 5 is buckled on the rotating table 2, a sealed space can be formed to ensure that a vacuum operation can be achieved in the sealing cover 5. After vacuuming, when the vacuum degree is greater than the vacuum degree inside the vacuum packaging bag, that is, when the ambient air pressure of the vacuum packaging bag is less than the internal air pressure of the vacuum packaging bag, the vacuum packaging bag expands, so that the food inside the vacuum packaging bag is evenly dispersed.

[0054] The sealing cover 5 is lifted and lowered by a lifting assembly. The lifting assembly includes a pad plate 6. The pad plate 6 is arc-shaped, and the two ends of the pad plate 6 are set at an inclined angle and fixed to the pad plate fixing seat 7 by bolts. There are three pad plate fixing seats 7. The pad plate 6 is set on the base 1 at the bottom of one side of the rotating table 2. A guide sleeve 8 is provided on the rotating table 2. A lifting column 9 is axially slidably provided in the guide sleeve 8. The bottom end of the lifting column 9 is rotatably provided with an abutting roller. The top end of the lifting column 9 is hinged to the bottom end of the hinged plate 10. The top end of the hinged plate 10 is hinged to the middle section of the swing arm 11. The two ends of the swing arm 11 are respectively connected to the rotating table 2 and the sealing cover 5. When the lifting column 9 rotates with the rotating table 2 to the position above the pad plate 6, the bottom end of the lifting column 9 abuts against the pad plate 6, causing the lifting column 9 to rise, thereby driving the swing arm 11 to swing, and driving the sealing cover 5 to rise. A vertical frame 12 is provided on the rotating table 2, and the two ends of the swing arm 11 are respectively hinged to the vertical frame 12 and the cover frame 13 provided on the sealing cover 5, and the vertical frame 12 and the cover frame 13 are also hinged by a connecting rod 14. Through the arrangement of the vertical frame 12, the swing arm 11, the cover frame 13 and the connecting rod 14, a quadrilateral mechanism is formed, thereby better realizing the lifting and lowering control of the sealing cover 5.

[0055] The flattening mechanism also includes a flattening assembly, which is used to flatten the vacuum packaging bag on the rotating table 2 within the sealing cover 5. The flattening assembly includes a flattening cylinder 15 installed on the sealing cover 5, which drives the pressure plate 16 within the sealing cover 5 to rise and fall. Through the arrangement of the flattening assembly, the flattening cylinder 15 drives the pressure plate 16 to rise and fall. When the vacuum packaging bag expands under the vacuum environment and the food inside is loosened, the vacuum packaging bag is squeezed, thereby flattening the food inside the vacuum packaging bag, that is, flattening the vacuum packaging bag and making the vacuum packaging bag more regular.

[0056] The leveling mechanism also includes a vibration assembly. A vibration opening is provided on the rotating table 2 at the bottom of the corresponding sealing cover 5. The vibration assembly includes a vibration plate 17 disposed at the vibration opening. The vibration plate 17 is driven to vibrate by a pneumatic vibrator 18 disposed on the rotating table 2. The vibration assembly also includes a fixed cover 19, which is fixed to the bottom of the rotating table 2 by bolts, and the vibration opening is located within the fixed cover 19. That is, the vibration plate 17 is completely captured by the sealing cover 17. The pneumatic vibrator 18 is disposed on the fixed cover 19. Through the configuration of the vibration assembly, when the vacuum packaging bag expands in a vacuum environment and the food inside is loosened, vibration is performed. Vibrating the food inside the vacuum packaging bag can make the food inside more loose and even.

[0057] A buffer assembly is provided at the bottom of the vibration plate 17. The buffer assembly includes a buffer plate 20 connected to the turntable 2 and a buffer rod 21 disposed at the bottom of the vibration plate 17. The buffer plate 20 is connected to the turntable 2 via a buffer plate connecting rod 22. The buffer rod 21 extends vertically through the buffer plate 20. Springs 23 are provided on the buffer rod 21 between the buffer plate 20 and the vibration plate 17 and between the buffer plate 20 and the bottom end of the buffer rod 21. The buffer assembly provides a buffering and vibration-absorbing effect for the vibration plate 17, while also preventing excessive pressure from the flattening cylinder 15 from damaging the vacuum packaging bag and the food inside.

[0058] A conveying mechanism is provided on the base 1 on one side of the rotating table 2 . When the sealing cover 5 rises, the conveying mechanism is used to unload the vacuum packaging bag on the rotating table 2 inside the sealing cover 5 .

[0059] The conveying mechanism includes a conveying frame 24, on which a conveying assembly is provided. The conveying assembly includes a conveying bracket 25, on which a plurality of rotating rollers 26 are arranged at intervals, on which a toggle wheel 27 is provided, and on which a power unit B28 for driving the plurality of rotating rollers 26 to rotate is provided.

[0060] Several rotating rollers 26 are connected by belt transmission. The power unit B28 is a motor reduction unit. The power unit B28 drives the rotating rollers 26 to rotate through the belt transmission. Several rotating rollers 26 are connected by belt transmission. Under the drive of the power unit B28, multiple rotating rollers 26 can rotate, and then the vacuum packaging bags can be transported.

[0061] The toggle wheel 27 includes a toggle hub, on which a plurality of toggle plates 29 are circumferentially distributed. The toggle plates 29 on the toggle hub rotate with the toggle wheel 27 to toggle the vacuum packaging bag to move, thereby realizing the conveying operation.

[0062] The conveyor frame 24 is equipped with a power unit C30, which is used to drive the conveyor bracket 25 to rise and fall. The power unit includes two cylinders, which are mounted on the conveyor frame 24 and drive the conveyor bracket 25 to rise and fall. The cylinders can drive the conveyor frame 24 to rise and fall. When the vacuum packaging bag needs to be unloaded, it is lowered. That is, when the vacuum packaging bag rotates with the turntable 2 to a position below the conveyor frame 24, it is lowered. The toggle wheel 27 descends and contacts the vacuum packaging bag. As the toggle wheel 27 rotates, the vacuum packaging bag is toggled to remove the vacuum packaging bag. When the vacuum packaging bag is no longer needed, the cylinder drives the conveyor frame 24 to rise. The simple structure and simple and reliable operation of the cylinders make it easy to achieve lifting and lowering control.

[0063] In the present application, by setting a leveling mechanism, the sealing cover 5 can be buckled on the rotating table 2 and vacuumized to form a certain vacuum degree in the environment of the vacuum packaging bag. When the vacuum degree is greater than the vacuum degree inside the vacuum packaging bag, that is, when the air pressure of the environment in which the vacuum packaging bag is located is less than the air pressure inside the vacuum packaging bag, the vacuum packaging bag expands, so that the food inside the vacuum packaging bag is evenly dispersed. After that, the air pressure inside the sealing cover 5 is restored, and the vacuum packaging bag returns to the vacuumed state, and the shape of the vacuum packaging bag becomes more uniform and regular. Then, by setting a lifting component, the sealing cover 5 is driven to rise and fall, and the rotating table 2 is rotated. When the sealing cover 5 rotates to a position above the pad 6, that is, a position on one side of the rotating table 2, the lifting component drives the sealing cover 5 to rise, and can rise to avoid the conveying mechanism set on one side of the rotating table 2. By rotating the rotating roller 26, the toggle wheel 27 to toggle the vacuum packaging bag, the vacuum packaging bag is unloaded from the rotating table 2, and the unloading is completed.

[0064] Through the arrangement of the present application, the vacuum packaging bag can be flattened, so that the shape of the vacuum packaging bag becomes uniform and regular, more beautiful, and more conducive to packaging and transportation.
