Description

Technical Field

[0001] The utility model relates to the technical field of food packaging weighing, in particular to a weighing device for convenient food packaging. Background Technique

[0002] Food packaging is an integral part of food products and one of the main processes in the food industry. It protects food from damage by biological, chemical, and physical external factors during the circulation process from the factory to the hands of consumers. It can also maintain the stable quality of the food itself, facilitate the consumption of food, and is the first to show the appearance of the food, attracting consumers. It has value beyond the material cost. During the food packaging process, it is necessary to weigh the food.

[0003] For example, the Chinese utility model provides a "weighing device for food packaging", with the publication number: CN213109878U. This application includes a countertop, on the top of which are respectively fixedly connected an electronic scale and an L-shaped frame located behind the electronic scale and extending above the electronic scale at one end. The rear side wall of the inner cavity of the L-shaped frame is fixedly connected with a display. The top of the L-shaped frame is fixedly connected with a conduit extending into the L-shaped frame. The bottom end of the conduit is fixedly connected with an electric butterfly valve communicating with the top wall of the inner cavity of the L-shaped frame. The bottom of the electric butterfly valve is communicated with an outlet pipe. The top end of the conduit is fixedly connected with a connecting pipe. This weighing device for food packaging has the advantages of facilitating material discharge, etc., and solves the problem in the prior art that when weighing powdery food with a weighing device for food packaging, the powdery food is likely to be blocked at the discharge pipe of the hopper, resulting in difficult material discharge, which affects the subsequent weighing and packaging of food.

The setting of the feed hopper 4 makes it convenient for personnel to add powdered food to the inside of the weighing box 5. The setting of the support frame 2 achieves the purpose of supporting the weighing box 5.

[0029] The working principle of the utility model is as follows: Through the setting of the belt conveyor 1, during the food packaging process, while supporting the container, it can drive the container to move below the feeding frame 19. Through the setting of the weighing box 5 and the material guiding frame 23, during the food packaging process, the powdered food to be weighed can be contained. And when it is necessary to weigh the powdered food to be packaged, by starting the second motor 24 to work, it can drive the feeding roller 6 and the material trough 25 to rotate. Under the action of the rotation of the material trough 25, the powdered food contained inside can fall to the top of the weighing platform 7. And under the action of the pressure sensor 21 and the display screen 3, the weight of the powdered food received on the top of the weighing platform 7 can be weighed and displayed. And when the weighed weight of the powdered food meets the packaging requirements, by starting the first motor 14 to work, it can drive the screw rod 12 to rotate. The rotation of the screw rod 12 can drive the moving plate 11 to move downward. The movement of the moving plate 11 can drive the support plate 8 to rotate along the bearing on the weighing box 5 through the connecting rod 9. The rotation of the support plate 8 can drive the pressure sensor 21, the weighing platform 7, the baffle plate 22, the vertical rod 29 and the roller 28 to rotate. While the weighing platform 7 can be inclined under the action of the rotation, the roller 28 can contact the inclined surface of the feeding frame 19 and push the vertical rod 29 and the baffle plate 22 to move upward along the inner cavity of the weighing platform 7 until the bottom of the baffle plate 22 can be separated from the bottom of the inner cavity of the weighing platform 7. Thus, the powdered food inside the weighing platform 7 can fall into the feeding frame 19 and then fall into the container on the top of the belt conveyor 1, achieving the effect of automatically weighing and discharging the powdered food. The overall operation is convenient and fast, bringing great convenience to the work of personnel, and effectively avoiding the fluctuation of the weighed weight of the powdered food affected by the container during the weighing process, ensuring the weighing quality during the food packaging process.
