Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, in particular to a glutinous rice and yam vacuum packaging machine. Background Art

[0002] Glutinous rice yam: The appearance is similar to ordinary yam, which is thick and slightly flat. The overall color is off-white or grayish white. There is a thin skin on the surface that is easy to peel off. After cutting, you can see that the inside is glutinous rice-like, and there is mucus attached to the cut surface. Due to the special shape of glutinous rice yam, it is mostly transported after peeling and cutting. Glutinous rice yam contains more mannan, multiple amino acids, mucin and water, which are easily invaded by mold and bacteria, resulting in quality deterioration. It is often preserved by vacuum packaging.

The turntable vacuum system includes several vacuum boxes and vacuum covers hinged to the vacuum boxes. The vacuum boxes are equipped with a clamping mechanism, a tightening mechanism, a synchronous drive mechanism, and a heat sealing mechanism. It utilizes the closing stroke of the vacuum cover to cooperate with the active airbag, and then utilizes the air pressure after the active airbag is squeezed to cooperate with hydraulic oil to achieve multi-point fixation of the packaging bag, automatic centering and correction clamping of the corn, and further fixation of the front and rear clamping, thereby greatly improving the vacuum packaging quality of the corn.

[0004] However, the above device still has the following defects: after bagging, the glutinous rice and yam pieces gather at the bottom of the packaging bag under the action of gravity, while the upper part of the packaging bag is in an empty state. There are vacuum blind spots between the glutinous rice and yam pieces concentrated at the bottom of the packaging bag, and it is difficult for quality inspectors or consumers to detect whether the glutinous rice and yam pieces hidden inside are of qualified quality; the packaging bag can only be vacuumed after the entire vacuum box is vacuumed, the vacuuming operation volume is large, the energy consumption is high, and the vacuuming efficiency of the packaging bag needs to be further improved.

After the transmission of the cross arm 23 and the swing arm 21, the two fixed clamping arms 22 frequently move away from or close to each other, and the bag mouth of the packaging bag is folded in half and then separated. The packaging bag containing the glutinous rice and yam pieces moves back and forth between the two halves of the inflatable airbags 6. During the movement, the elastic extrusion force of the airbag 6 acts on the glutinous rice and yam blocks in the packaging bag, so that the aggregated glutinous rice and yam blocks are dispersed to a single layer state under the action of the extrusion force, further improving the dispersion of the glutinous rice and yam blocks in the packaging bag, and providing a guarantee for the subsequent vacuum exhaust of the packaging bag; under the action of the tension spring 34, the reset speed of the swing arm 21 can be further increased to improve the up and down displacement vibration effect of the packaging bag, and the limiting screw 35 can limit the downward position of the drive seat 24 to avoid excessive downward movement of the drive seat 24 to prevent the drive wheel 30 from moving out of the open slide groove 29.

[0039] The bag opener 36 is used for opening the packaging bag. After the bag clamping and loading mechanism 18 clamps the packaging bag in the closed state, the first lifting drive mechanism 38 drives the first drive to move downward so that the first suction cups 40 are respectively located on both sides of the packaging bag. After the first drive is started, the two first suction cups 40 move synchronously toward the packaging bag and adsorb the outer walls of the two sides of the packaging bag. Then the first drive is started again, the two first suction cups 40 move away from each other, and the bag opening of the packaging bag is opened. It should be noted that at this time the output end of the fourth telescopic cylinder 25 is in a shortened state, the driving seat 24 moves freely up and down, and the two fixed clamping arms 22 approach each other under the pulling force of the first suction cup 40 to realize the opening of the packaging bag. Then the second lifting drive mechanism 41 drives the second drive to move downward, and the two inner support plates 43 are inserted into the bag opening of the packaging bag in the open state 8. The second drive is started, the two inner support plates 43 move away from each other, and the bag opening of the packaging bag is fully opened, so that the operator can load the glutinous rice and yam pieces into the packaging bag.

[0040] The second suction cup 56 can be used to absorb a packaging bag stacked on the lifting frame 51, and then the rotary cylinder 54 drives the telescopic rotating arm 55 to rotate 90 degrees. The telescopic rotating arm 55 extends and sends the packaging bag between the fixed clamp 31 and the movable clamp 32 at the two fixed clamp arms 22 on the bag clamping and loading mechanism 18, thereby realizing automatic loading of the packaging bag to the bag clamping and loading mechanism 18, thereby improving the loading convenience of the packaging bag; as the packaging bags are used, the height of the stacked packaging bags becomes smaller. At this time, by starting the seventh telescopic cylinder 50, the output end of the seventh telescopic cylinder 50 is shortened, the lifting frame 51 moves up, and the packaging bag moves up between the limiting angle supports 52, so that the bag suction assembly can suck the packaging bag on the lifting frame 51.

[0041] When the opening of the packaging bag is stretched open by the inner support plate 43, the output end of the eighth telescopic cylinder 58 extends, and the loading bell mouth 59 moves downward and extends into the packaging bag in the open state, and the glutinous rice and yam blocks are loaded into the packaging bag through the loading bell mouth 59, which can prevent the mucus on the glutinous rice and yam blocks from adhering to the bag opening of the packaging bag, and prevent residual mucus from affecting the sealing of subsequent packaging bags. At the same time, it can prevent excessive mucus from adhering to the upper part of the packaging bag to form stains, so as to ensure the sensory cleanliness of the upper part of the packaging bag.

[0042] After the bag is packed up, the bag is put into the bag and the glutinous rice and yam pieces are put into the bag. The nozzle 15 is inserted into the bag opening of the packaging bag and presses the bag opening of the packaging bag against the top of the first heat-sealing plate 9 and the second heat-sealing plate 10. The air extraction nozzle 15 is sealed with the inner wall of the packaging bag, and the vacuum pump 12 is started to extract the air in the packaging bag. At the same time, the air extracted by the vacuum pump 12 enters the two air bags 6 through the air inflation pipe 14 and the air distribution pipe 17. As the air in the packaging bag decreases, the two air bags 6 gradually expand and squeeze the two sides of the packaging bag. Under the squeezing action, the air in the packaging bag is accelerated to be discharged. Since the outer wall of the glutinous rice and yam blocks is adhered to mucus, the friction resistance between the glutinous rice and yam blocks is small. Under the squeezing action of the air bags 6, the glutinous rice and yam blocks are separated from each other and gradually change from a gathered state to a dispersed and flat state in the packaging bag. The distance between adjacent glutinous rice and yam blocks becomes larger, thereby reducing the dead angle of air extraction between the glutinous rice and yam blocks. The inner wall of the packaging bag is tightly fitted with the glutinous rice and yam blocks, thereby realizing the flat positioning and vacuuming of the glutinous rice and yam blocks in the packaging bag.

[0043] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication between them; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise expressly limited. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
