Description

Technical Field

[0002] X-ray food foreign body detector is an important part of ensuring quality in the production, processing and packaging of food. It is used to detect metal foreign bodies and non-metallic foreign bodies with high density mixed in the product. In addition, it can also detect product missing, package damage and weight. In the HACCP standard currently widely used in large-scale food processing and packaging industries, X-ray food foreign body detector is an indispensable detection equipment. The market size of my country's food safety testing industry has basically maintained a growth rate of about 20% in recent years.

[0003] X-ray food foreign body detectors are mainly composed of radiation sources, linear array detectors, image workstations and fixed racks.

Among them, the radiation sources used in high-end X-ray food foreign body detectors are mainly imported because they have high requirements for continuous working reliability and radiation leakage safety, which are difficult for ordinary X-ray machines to meet.

[0036] Working principle:

[0037] like Figure 5 and Figure 6As shown, the tube box 1 is electrically connected to the control box 2, the control box 2 is connected to the host computer for communication, the control box 2 is connected to the external power supply, and outputs high-frequency alternating current to the tube box 1 after passing through the rectifier circuit, voltage stabilizing circuit, and high-frequency inverter circuit on the internal control board 5. After receiving, the tube box 1 is stepped up by the main transformer 8 and stepped up and rectified by the voltage multiplier board 3, and then outputs positive and negative high-voltage direct current to both ends of the tube to form a high-voltage electric field. The filament driving circuit on the control board 5 in the control box 2 generates a filament driving signal to the tube box 1. After receiving, the tube box 1 is isolated and stepped down by the filament transformer assembly 7, and then applied to the filament inside the tube assembly 4 to light the filament. After the voltage is applied and the filament is lit, the tube assembly 4 generates X-rays and outputs them through the ray port 120. The control box 2 also outputs a cooling fan driving signal to the tube box 1, so that the first cooling fans 111 on both sides of the tube box 1 work. When the control box 2 and the tube box 1 start working, the cooling fan starts working to dissipate heat. A temperature sensor is provided inside the tube box 1, and the temperature sampling signal is fed back to the control board 5 of the control box 2. When the temperature signal is higher than 50 degrees, the circulating oil pump 6 in the tube assembly 4 starts to work, accelerating the internal oil circulation speed and greatly increasing the heat dissipation of the tube assembly; when the oil temperature is lower than 45 degrees, the circulating oil pump 6 stops working, thereby ensuring that the temperature inside the tube box 1 is appropriate and avoiding damage to the X-ray tube 44 assembly or shortening its life due to high temperature. A sampling circuit is provided on the voltage multiplier board 3. When the tube assembly 4 emits X-rays, the actual state signal collected is fed back to the control board 5, and the operational amplifier circuit on the control board 5 is compared with the set signal, thereby forming a closed-loop feedback.
