Technical Field

[0001] The utility model relates to the technical field of food detection, and particularly relates to a weighing and screening device for food detection. Background Technique

[0002] Food packaging is an integral part of food products. It is 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. It facilitates the consumption of food and is the first to show the appearance of the food, attracting consumers. It has value beyond the material cost.

[0003] In the current bagging process of bagged food, it is not possible to well ensure that the weight of the food in each bag meets the standard requirements. When the food content in the bag is higher than the standard content, it will cause losses to the merchant. When the food content in the bag is lower than the standard content, the consumer value cannot be guaranteed. Therefore, it is necessary to weigh and screen the food. Most of the existing weighing and screening are completed manually. Through a dynamic weighing detector, the weight of the food is detected. If it is unqualified, it is manually selected. This method is time-consuming and laborious, with low efficiency. In view of this, a weighing and screening device for food detection is now proposed. Content of the Utility Model

This method has a high degree of automation and fast screening, can adapt to the high-efficiency production of food, further improve the weight control of food when leaving the factory, and the weighing and screening device for food detection can correct the inclined food through two T-shaped deviation rectifying plates, so that it can accurately pass through the dynamic weighing sensor for accurate weighing, which is convenient for subsequent screening.

[0040] Working principle: When the weighing and screening device for food detection is in use, the food to be weighed is placed on the first conveyor belt 1 for transportation. At this time, by starting two first hydraulic cylinders 5, the two first hydraulic cylinders 5 drive two first hydraulic rods 6 sleeved on the inner surface to move towards the opposite side through operation. At the same time, the two first hydraulic rods 6 drive two sliding blocks 7 sleeved on the inner surface to rotate and move towards the opposite side in two first sliding grooves 9. While moving, the two sliding blocks 7 drive two T-shaped deviation rectifying plates 8 sleeved on the outer surface to move towards the opposite side. While moving, the two T-shaped deviation rectifying plates 8 gradually rotate on the vertical plates on the relative two sides of the first conveyor belt 1 and gradually become inclined. At this time, the food can be corrected by the two T-shaped deviation rectifying plates 8 to keep it at the center of the first conveyor belt 1 for transportation. At this time, the food passes above the dynamic weighing sensor 10, and the weighing threshold is set manually through the weighing threshold controller 11. If it meets the standard, the food is transported through the second conveyor belt 2 and the third conveyor belt 3 in sequence. If it does not meet the standard, at this time, by starting two second hydraulic cylinders 13, the two second hydraulic cylinders 13 drive two second hydraulic rods 14 sleeved on the inner surface to move downward through operation. The two second hydraulic rods 14 apply a downward pulling force to the second conveyor belt 2 rotatably connected at the upper end, so that the second conveyor belt 2 slides downward on the inner surfaces of two second sliding grooves 16 through the fixing rods 17 fixedly installed on the lower surface, making the second conveyor belt 2 gradually become inclined. At this time, the second conveyor belt 2 is connected to the fourth conveyor belt 4, and at this time, the food with unqualified weight can be transported.
