DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] The present invention provides a food packaging machine, comprising a machine body 1 and a universal wheel 11, wherein the top of the machine body 1 is sealed with a sealing cover 2, and a rice bin 3 is fixedly connected to the machine body 1;

[0033] A feeding cavity 4 is connected below the rice bin 3, one end of the feeding cavity 4 passes through the machine body 1 and extends to the outside of the machine body 1, and a discharge port 41 is provided at one end of the feeding cavity 4 extending out of the machine body 1;

[0034] A packaging barrel 5 is provided directly below the discharge port 41, and the packaging barrel 5 is fixedly connected to the machine body 1 via a connecting plate 51;

[0035] The inner wall of the feeding cavity 4 is provided with one or more hollow protrusions 42, and the inner wall of the feeding cavity 4 is provided with one or more through holes 43. An air blowing pipe 44 is fixedly connected to the outer side of the feeding cavity 4, and one end of the air blowing pipe 44 is connected to the hollow protrusion 42 through the through hole 43 provided on the inner wall of the feeding cavity 4, and the other end of the air blowing pipe 44 passes through the machine body 1 and extends to the upper side of the edge of the packaging barrel 5;

[0036] A feeding auger 45 is installed in the feeding cavity 4, and a crank 46 is provided at one end of the feeding auger 45 away from the discharge port 41;

[0037] One end of the crank handle 46 is fixedly connected to the feeding auger 45, and the other end thereof penetrates the feeding cavity 4 and the machine body 1, and is rotatably connected to the feeding cavity 4 and the machine body 1;

[0038] When the food packaging machine is in use, the universal wheel 11 is pushed to push the food packaging machine to a designated position, and the rice is loaded into the rice bin 3. The sealing cover separates the rice from the air. When the customer purchases, the packaging bag is put into the packaging barrel 5, and the crank 46 is shaken. The rice enters the feeding cavity 4 and moves forward under the push of the auger 45, and is poured out from the discharge port 41 and falls into the packaging bag. At the same time, the rice squeezes the hollow protrusion 42 when moving in the feeding cavity 4, and the air in the hollow protrusion 42 is squeezed into the blowing pipe 44 and blown from the other end of the blowing pipe 44 to the edge of the packaging bag on the packaging barrel 5. The generated airflow can make the packaging bag close to the edge of the packaging barrel 5. The edge of the packaging bag is realized to prevent rice from spilling outside the packaging bag while loading, thereby reducing food waste. At the same time, the present invention stores rice in the rice bin 3 and seals it with a sealing cover, and matches the crank 46 with the auger 45, the hollow protrusion with the blowing pipe 44. Compared with the prior art, in which the rice is directly exposed to the air for sale in supermarkets, the present invention avoids exposing the rice to the air, avoids direct contact between the rice and multiple consumers, and may cause unsanitary conditions. At the same time, the blowing pipe 44 blows air toward the edge of the packaging bag while feeding, thereby avoiding rice waste caused by the packaging bag falling off during packaging.

[0039] As a specific embodiment of the present invention, an exhaust pipe 6 is provided directly below the feeding chamber 4, one end of the exhaust pipe 6 is welded to the inner wall of the body 1, and the other end is connected to a transmission shaft 7, one end of the transmission shaft 7 extends into the exhaust pipe 6, and the other end is rotatably connected to the inner wall of the body 1, and an exhaust pipe 61 that penetrates the body 1 is connected below the exhaust pipe 6;

[0040] One end of the transmission shaft 7 extending into the exhaust pipe 6 is fixedly connected to the exhaust fan 72, and the other end passes through the exhaust pipe 6 and is rotatably connected to the inner wall of the body 1;

[0041] The packaging barrel 5 is evenly distributed with air passages 52, one end of the air passage 52 is connected to a suction cup 53, and the other end is connected to a first air extraction pipe 62;

[0042] One end of the exhaust pipe 6 away from the exhaust fan 72 is connected to the first exhaust pipe 62, and one end of the first exhaust pipe 62 away from the air duct 52 passes through the machine body 1 and is connected to the exhaust pipe 6;

[0043] A driving gear 47 is installed at one end of the crank 46 located inside the body 1, and a driven gear 71 is installed at one end of the transmission shaft 7 away from the fan 72, and the driving gear 47 meshes with the driven gear 71;

[0044] When the crank 46 rotates, the driving gear 47 rotates accordingly, driving the driven gear 71, and the driven gear 71 drives the exhaust fan 72 to rotate, generating an air pressure difference in the exhaust pipe 6, thereby reducing the air pressure in the No. 1 exhaust pipe 62, realizing the contraction of the suction cup, and the suction of the suction cup can make the edge of the packaging bag further close to the packaging barrel 5, reducing the rice spilled outside the packaging bag and further reducing the waste of rice. The present design realizes that while loading, the blowing pipe 44 blows air above the edge of the packaging bag and the suction pipe sucks air below the packaging bag, so that the packaging bag is further close to the packaging barrel 5, further reducing the possibility of the packaging bag falling off and reducing the waste caused by rice spilled outside the packaging bag.

[0045] As a specific embodiment of the present invention, the side wall of the rice bin 3 is provided with an exhaust hole 31, and a waterproof breathable membrane 311 is provided in the exhaust hole 31;

[0046] One end of the exhaust hole 31 is connected to a second exhaust pipe 63, and one end of the second exhaust pipe 63 away from the exhaust hole 31 is connected to the exhaust pipe 6; a one-way valve 631 is installed in the second exhaust pipe 63;

[0047] When the exhaust fan 72 rotates, the excess air in the rice bin 3 is sucked out through the exhaust hole 31 through the No. 2 exhaust pipe 63, so as to reduce the air content in the rice bin 3, which is helpful to improve the storage environment of the rice, keep the rice dry, and prevent the rice from getting damp and deteriorating. The waterproof and breathable membrane 311 can prevent moisture from entering the rice bin 3 through the exhaust hole 31 and maintain the air permeability of the rice bin 3. The one-way valve 631 can prevent the air in the exhaust pipe 6 from flowing back. The present invention cooperates the No. 1 blowing pipe 44, the No. 2 blowing pipe 44 and the exhaust pipe to achieve blowing above the edge of the packaging bag and sucking below the edge of the packaging bag while feeding, so as to further make the packaging bag close to the packaging barrel 5, improve the packaging quality of the rice, and achieve exhaust in the rice bin 3, thereby improving the storage environment of the rice and reducing the probability of the rice getting damp and rotting.

[0048] As a specific embodiment of the present invention, one or more heating plates 21 are fixedly connected to the side of the sealing cover 2 that contacts the rice bin 3, and the heating plates 21 are evenly distributed on the sealing cover 2;

[0049] The rice bin 3 is heated by the design of the single heating plate 21, which further improves the storage environment of the rice. At the same time, the single heating plate 21 evenly distributed on the sealing cover can be inserted into the rice bin 3 to separate the rice, prevent the rice from piling up, and avoid the rice from getting moldy and rotting.

[0050] As a specific embodiment of the present invention, a door cabinet 12 is provided on the side wall of the machine body 1, a door body 123 is connected to one side of the door cabinet through a hinge, and an activated carbon bag 13 is placed in the machine body 1;

[0051] The activated carbon bag 13 can effectively absorb water vapor and impurities, further improve the storage environment of rice, and prevent the rice from being damp and contaminated. The door 123 opened on the side wall of the body 1 can conveniently replace the activated carbon bag.

[0052] As a specific embodiment of the present invention, the sealing cover 2 is provided with a groove 22, a label column 23 is provided on one side of the groove 22, and the sealing cover is made of a transparent material;

[0053] The groove 22 is used as a display stand to hold samples so that customers can understand the rice. The label 23 on one side of the groove 22 indicates the type and price of the rice. When the customer decides to buy, he can observe whether the rice is consistent with the sample through the transparent sealing cover.

[0054] The specific working process is as follows: when the food packaging machine is in use, the universal wheel 11 is pushed to push the food packaging machine to the designated position, the rice is loaded into the rice bin 3, and the sealing cover separates the rice from the air. When the customer buys, the packaging bag is put into the packaging barrel 5, and the crank 46 is shaken. The rice enters the feeding cavity 4 and moves forward under the push of the auger 45, and is poured out from the discharge port 41 and falls into the packaging bag. At the same time, the rice squeezes the hollow protrusion 42 when moving in the feeding cavity 4, and the air in the hollow protrusion 42 is squeezed into the blowing pipe 44, and is blown from the other end of the blowing pipe 44 to the edge of the packaging bag on the packaging barrel 5. The generated airflow can make the packaging bag close to the packaging bag. The edge of the packaging barrel 5 prevents rice from spilling outside the packaging bag while loading, thereby reducing food waste. At the same time, the present invention stores rice in the rice bin 3 and seals it with a sealing cover, and matches the crank 46 with the auger 45, the hollow protrusion with the blowing pipe 44. Compared with the prior art, in which rice is directly sold in the supermarket exposed to the air, the present invention avoids exposing the rice to the air, avoids direct contact between the rice and multiple consumers, and may cause unsanitary conditions. It realizes that the blowing pipe 44 blows air toward the edge of the packaging bag while feeding, thereby avoiding rice waste caused by the packaging bag falling off during packaging.

[0055] When the crank 46 rotates, the driving gear 47 rotates accordingly, driving the driven gear 71, and the driven gear 71 drives the exhaust fan 72 to rotate, generating an air pressure difference in the exhaust pipe 6, thereby reducing the air pressure in the No. 1 exhaust pipe 62, realizing the contraction of the suction cup, and the suction of the suction cup can make the edge of the packaging bag further close to the packaging barrel 5, reducing the rice spilled outside the packaging bag and further reducing the waste of rice. The present design realizes that while loading, the blowing pipe 44 blows air above the edge of the packaging bag and the suction pipe sucks air below the packaging bag, so that the packaging bag is further close to the packaging barrel 5, further reducing the possibility of the packaging bag falling off and reducing the waste caused by rice spilled outside the packaging bag.

[0056] When the exhaust fan 72 rotates, the excess air in the rice bin 3 is sucked out through the exhaust hole 31 through the No. 2 exhaust pipe 63, so as to reduce the air content in the rice bin 3, which is helpful to improve the storage environment of the rice, keep the rice dry, and prevent the rice from getting damp and deteriorating. The waterproof and breathable membrane 311 can prevent moisture from entering the rice bin 3 through the exhaust hole 31 and maintain the air permeability of the rice bin 3. The one-way valve 631 can prevent the air in the exhaust pipe 6 from flowing back. The present invention cooperates the No. 1 blowing pipe 44, the No. 2 blowing pipe 44 and the exhaust pipe to achieve blowing above the edge of the packaging bag and sucking below the edge of the packaging bag while feeding, so as to further make the packaging bag close to the packaging barrel 5, improve the packaging quality of the rice, and achieve exhaust in the rice bin 3, thereby improving the storage environment of the rice and reducing the probability of the rice getting damp and rotting.

[0057] The activated carbon bag 13 can effectively absorb water vapor and impurities, further improve the storage environment of rice, and prevent the rice from being damp and contaminated. The door 123 opened on the side wall of the body 1 can conveniently replace the activated carbon bag.

[0058] The groove 22 is used as a display stand to hold samples so that customers can understand the rice. The label 23 on one side of the groove 22 indicates the type and price of the rice. When the customer decides to buy, he can observe whether the rice is consistent with the sample through the transparent sealing cover.
