Automatic weighing and dispensing structure for pre-packaged food

Abstract

This utility model belongs to the field of food packaging technology and discloses an automatic weighing and dispensing structure for pre-packaged food. It includes a support frame with a support ring fixedly connected to it. A ring-shaped pressure sensor is connected to the top of the support ring, and a fixed ring is connected to the top of the ring-shaped pressure sensor. A storage container is connected to the inner wall of the fixed ring. The ring-shaped pressure sensor can weigh the storage container and its connected structures, indicating any reduction in material. The weighing platform can weigh the dispensed product. The combination of these two components ensures accurate weighing data, which is beneficial for food weighing and dispensing. A shock-absorbing component prevents vibrations generated by the motor structure on the sealed cover from being transmitted to the ring-shaped pressure sensor, avoiding interference with the weighing data.

[0030] like Figures 1 to 5 As shown, this utility model provides an automatic weighing and dispensing structure for pre-packaged food, including a support frame 1, a support ring 2 fixedly connected to the support frame 1, an annular pressure sensor 3 connected to the top of the support ring 2, a fixing ring 4 connected to the top of the annular pressure sensor 3, a storage container 5 connected to the inner wall of the fixing ring 4, a sealing cover plate 7 connected to the top of the storage container 5 through a shock-absorbing component 6, a stirring component 8 installed on the sealing cover plate 7, a discharge pipe 9 connected to the bottom of the storage container 5, a discharge port 10 provided at the bottom of the discharge pipe 9, and a shifting component 11 provided on one side of the storage container 5 at a position corresponding to the discharge port 10;

[0031] The transposition assembly 11 includes a crossbeam 111 fixedly connected to the feed pipe 9. A first motor 112 is mounted on the crossbeam 111. The first motor 112 is connected to a drive gear 113 via a motor shaft. The drive gear 113 meshes with a driven gear 114. A rotating column 115 is fixedly connected to the center of the bottom of the driven gear 114. The bottom end of the rotating column 115 passes through the crossbeam 111 and is fixedly connected to a connecting frame 116. The connecting frame 116 is connected to multiple evenly distributed placement plates 117. The position of the placement plates 117 corresponds to the feed port 10. A weighing platform 118 is provided on the top of the placement plates 117. A limit groove plate 119 is provided on the top of the weighing platform 118. The annular pressure sensor 3 can weigh the storage container 5 and its connected structures to detect any reduction in material. The weighing platform 118 can weigh the packaged products. The combination of the two can ensure the accuracy of the weighing data, which is beneficial for the weighing and packaging of food.

[0032] Specifically, the shock-absorbing component 6 includes a shock-absorbing pad ring 61 located on the top of the storage container 5, a sealing cover plate 7 located on the shock-absorbing pad ring 61, and a plurality of evenly distributed positioning rods 62 fixedly connected to the top of the fixing ring 4. The top of the positioning rods 62 passes through the sealing cover plate 7 and is connected to a rubber end cap 63. The shock-absorbing component 6 prevents the vibration generated by the motor structure on the sealing cover plate 7 from being transmitted to the annular pressure sensor 3, thus avoiding interference with the weighing data. Furthermore, the feeding pipe 9 and its internal spiral blades 12 can prevent material blockage, which is beneficial for food packaging.

[0033] Furthermore, a through hole 64 is provided on the sealing cover plate 7 at the position corresponding to the positioning rod 62, and the positioning rod 62 passes through the through hole 64.

[0034] Furthermore, the stirring assembly 8 includes a second motor 81 located on top of the sealing cover plate 7. The output end of the second motor 81 is connected to a stirring shaft 82. The stirring shaft 82 extends through the sealing cover plate 7 into the storage container 5. A stirring rod 83 is provided on the stirring shaft 82 inside the storage container 5.

[0035] It is worth noting that the bottom end of the stirring shaft 82 extends into the feed pipe 9, and the stirring shaft 82 inside the feed pipe 9 is equipped with a spiral blade 12, the structure of which matches the feed pipe 9.

[0036] It is worth noting that the limiting groove plate 119 is a certain distance away from the feeding port 10, and the container of the packaged food is placed on the limiting groove plate 119.

[0037] Among them, the ring pressure sensor 3, the second motor 81, the first motor 112, and the weighing platform 118 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0038] Working principle and process: First, place the food to be packaged into the storage container 5, place the packaging container on the limiting groove plate 119 of the switching component 11, open the feeding port 10, and start the second motor 81 of the stirring component 8. Then, the stirring shaft 82 drives the stirring rod 83 to rotate, which can stir the food in the storage container 5 and prevent some powdery food from sticking together. The spiral blades 12 in the feeding pipe 9 can output the food and then fall onto the packaging container. The ring pressure sensor 3 can weigh the storage container 5 and its connected structure to weigh the reduced material. The weighing platform 118 can weigh the packaged product. The combination of the two can ensure the accuracy of the weighing data and facilitate the weighing and packaging of food. Start the first motor 112 of the switching component 11, then the driving gear 113 drives the driven gear 114 to rotate, and then the rotating column 115 drives the connecting frame 116 to rotate, which can change the position of the placement plate 117 so as to remove the packaging container containing food and improve the packaging efficiency.
