Description

Technical Field

[0001] The invention relates to the technical field of food detection, in particular to a food quality detection device. Background Art

[0002] After the production and packaging of various foods, they need to be inspected for quality. For example, the weight of the food can reflect whether the food filling reaches the preset value. In the existing food inspection device, there is a load-bearing sensor installed on the inner side of the conveyor belt to inspect the food conveyed by the conveyor belt. However, the conveyor belt may be affected by vibration, temperature, humidity and other factors during operation, which makes it difficult for the weighing sensor to maintain high precision and stability. This instability may introduce errors and affect the accuracy of the measurement results.

[0003] To solve this problem, a patent with application number CN202110031210.7 proposes a food quality detection device that is easy to maintain. The device drives the connecting plate and the extension plate to move through a stepper motor through a rotating roller and a conveyor belt. The extension plate pushes the food to the left, and the food is moved to the upper part of the flat pressing plate by the extension plate. The food pushes the flat pressing plate downward by gravity, and the pressure sensor is subjected to force to detect the weight of the food to see whether it meets the standard, thereby placing the food directly on the weighing equipment for testing, avoiding the problem that the conveyor belt may be affected by vibration, temperature, humidity and other factors during operation, which makes it difficult for the weighing sensor to maintain high accuracy and stability;

[0004] However, when this device is used in practice, if the food is to be kept relatively still on the weighing device in order to improve the detection accuracy, it is necessary to control the transmission belt through a program to intermittently transport the food, thereby ensuring that the food is kept relatively still relative to the weighing device during detection. This operation will repeatedly start the conveyor belt discontinuously and reduce the service life of the transmission belt. For this reason, we propose a food quality detection device.

[0042] Example 1: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a food quality detection device, including a mounting frame 1, and also including:

[0043] A material guide plate 2 is fixedly connected to the mounting frame 1 and is used for placing food;

[0044] The conveyor belt 3 is arranged on the mounting frame 1 and is located above the guide plate 2;

[0045] A plurality of material shifting plates 4 are evenly and equidistantly arranged on the conveyor belt 3. When the conveyor belt 3 is started, the material shifting plates 4 are used to push the food to move along the material guide plate 2.
