Technical Field
[0001] The utility model relates to the technical field of X-ray foreign body detectors, in particular to a protective device for X-ray foreign body detectors. Background Art
[0002] X-ray foreign body detector is also called X-ray foreign body detector. It generates X-rays and uses the penetrating ability of X-rays to detect foreign matter mixed in food. When food is processed and packaged, such as meat puree and fruit puree, some foreign matter, such as metal, glass, stone, plastic and rubber, will appear. These foreign matter not only affects the quality of food, but also some foreign matter is difficult to detect with the naked eye, and it is easy for consumers to eat it by mistake, causing food safety accidents. Therefore, X-rays are generally used to detect whether there are foreign matter in food, which requires the use of X-ray foreign body detector.
[0003] The X-ray foreign body detector currently in use mainly includes a detection box, a conveying mechanism for conveying food, a light source system installed in the detection box and used to emit X-rays, and an image acquisition system for collecting projected X-rays. During the detection process, the food is transported to the detection box through the conveying mechanism, and the detection box is equipped with a light source system for emitting X-rays. At present, the inlet and outlet of the detection box are both equipped with barrier curtains to block X-rays. However, when food enters or leaves the detection box, the barrier curtains will swing, causing X-ray leakage. X-rays are very harmful to the human body, so the current X-ray foreign body detection equipment has poor safety and cannot meet the use requirements. Summary of the invention

Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0019] like Figure 1-3 As shown, a protective device for an X-ray foreign body detector comprises a frame 1, the frame having a detection cavity, a feed inlet and a discharge outlet are respectively provided at both ends of the frame, and a barrier curtain 2 is installed downwardly at the upper ends of the feed inlet and the discharge outlet;
[0020] The frame is respectively installed with a feed conveyor belt bracket and a discharging conveyor belt bracket opposite to the feed port and the discharging port, a feed conveyor belt 3 is installed on the feed conveyor belt bracket, and a discharging conveyor belt 4 is installed on the discharging conveyor belt bracket, and the loading end of the feed conveyor belt and the unloading end of the discharging conveyor belt are both located outside the frame; a detection conveyor belt bracket is installed in the frame, a detection conveyor belt 5 is installed on the detection conveyor belt bracket, and the loading end and unloading end of the detection conveyor belt are respectively located below the unloading end of the feed conveyor belt and the loading end of the discharging conveyor belt; a blocking protection structure is also symmetrically installed in the frame, and a lifting structure is arranged in the frame.
[0021] In this way, the food to be inspected is placed on the feed conveyor belt, which drives the food through the barrier curtain at the feed port and then drops onto the inspection conveyor belt. The light source system installed in the frame emits X-rays, and the image acquisition system is used to acquire images. The inspection conveyor belt drives the food to move to the lifting structure, and the lifting structure lifts the inspected food to the discharge conveyor belt. The discharge conveyor belt drives the food through the barrier curtain at the discharge port and then transmits it outward.
[0022] During the detection process, although the barrier curtain at the feed port is in a swinging state, the symmetrical barrier protection structure blocks the rays at the feed port and the discharge port, which can reduce the leakage of X-rays.
[0023] During implementation, the barrier protection structure includes a shield 6 and an upper baffle, the upper baffle is fixedly installed in the frame, the shield includes an integrally formed vertical plate 11, a curved plate 12 and a horizontal plate 13, the vertical plate is slidably fitted with the baffle, the curved plate is bent and extended outward, the upper end of the vertical plate is bent to the side away from the upper baffle to form a connecting section 14, and a lifting cylinder 8 is fixedly installed on the outer side of the frame facing the horizontal plate and the connecting section, and the cylinder rod of the lifting cylinder passes through the frame and is fixedly connected to the horizontal plate and the connecting section respectively. The shield is arranged between the light source system and the barrier curtain, the light source system and the barrier curtain are staggered, and the light source system is located below the barrier curtain in the vertical direction. When blocking X-rays, the curved plate and the baffle form a light barrier to the barrier curtain. According to the height required by different foods, the shield is driven to rise and fall by the lifting cylinder to avoid interference between the shield and the food.
[0024] During implementation, a lower baffle is fixedly installed in the frame, and the lower baffle is located between the feeding conveyor belt bracket and the detection conveyor belt bracket. The barrier effect can be further improved. The lower baffle is fixedly connected to the feeding conveyor belt bracket and the detection conveyor belt bracket.
[0025] During implementation, a plurality of reinforcing rods 15 are fixed between the vertical plate and the curved plate to improve the strength of the protective cover.
[0026] During implementation, the lifting structure includes an inclined lifting conveyor belt bracket, on which a lifting conveyor belt 21 is installed, and a plurality of lifting plates 22 are installed at intervals on the outer side of the lifting conveyor belt. The loading end of the lifting conveyor belt is located below the unloading end of the detection conveyor belt, and the unloading end of the lifting conveyor belt is located above the loading end of the discharge conveyor belt. The detection conveyor belt drives the food to move, and when it moves to the unloading end, due to inertia, the food can reach the lifting conveyor belt. The lifting conveyor belt is inclined, which can drive the food to be lifted. After being lifted into place, due to inertia, the food can reach the discharge conveyor belt and complete the lifting.
[0027] Specifically, a light source system for emitting X-rays and an image acquisition system for collecting projected X-rays are installed in the frame, both of which are existing systems and will not be described in detail.
[0028] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention.
