　　The performance of security inspection equipment has improved a lot compared with previous years. Security inspection X-ray machines are essential equipment for security inspection channels. How this equipment can distinguish dangerous items such as explosives, drugs, guns, knives, etc., we need to start with the principle of security inspection machines.

　　x-ray machines

　　ZA5030A

　　The security inspection machine is an electronic device that uses a conveyor belt to send the checked luggage into the X-ray inspection channel to complete the inspection. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part, generating an X-ray trigger signal, triggering the X-ray source to emit an X-ray beam.

　　The X-ray beam passes through the inspected objects on the conveyor belt, and the X-rays are absorbed by the inspected objects and finally bombard the semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these very weak signals are amplified and sent to the signal processing chassis for further processing. After these signals are processed, they are displayed on the display screen.

　　”No matter how many layers a package has, X-rays can penetrate it and display the items in the package layer by layer.” Dangerous items are identified by different colors. Multi-energy colored organic matter is displayed in orange, inorganic matter is displayed in blue, and mixtures are displayed in green. High energy/low energy are switched to display. High energy displays metals, etc., and low energy displays non-metals. In the image display system, the X-ray sensor L-shaped photodiode array detector (multiple energies are optional), 12-bit depth, high penetration display increases the brightness of dark areas in the image, so that items hidden behind highly absorbent objects are clearly displayed. Low penetration display increases the contrast of low absorption (easy to penetrate) objects, making easy to penetrate objects clearer; therefore, the X-ray security inspection machine is not a decoration, but actually undertakes the work of protecting railway safety.

　　So how does the security inspection machine detect these dangerous items?

　　1. Image monitoring method

　　Image monitoring method directly determines the object from the X-ray image configuration. Therefore, whether the object is suspicious depends on the image on the monitor or display. Unusual objects or objects with different shapes that appear on the display or monitor should be considered suspicious objects. Objects that cannot be accurately identified should also be considered suspicious objects and need to be carefully investigated. The image can be located and analyzed as needed.

　　2. Color analysis method

　　The color analysis method is to identify the type of material based on the different colors that different materials show under the x-ray image. The various colors that appear on the monitor are a reflection of the density, quality and quantity of the object. Therefore, the quality of the object can be evaluated based on the depth of the image color.

　　Light yellow is generally the color of a single piece of clothing, thin plastic, and a small amount of paper.

　　Orange is generally the color of soap, soap, explosives, drugs, wood, leather products, etc.

　　Dark orange is generally the color of a large number of books, paper, RMB, high-concentration liquids, large bags of rice and flour, etc.

　　Blue is the color of inorganic substances such as copper, iron, and zinc. Thick cables, stun guns, bullets, gun barrels, guns, and knives show different shades of blue. Green is the color of mixtures, stainless steel products, cables, etc. show different shades of green. Red is the color of impenetrable objects, mostly heavy metals and thick objects.

　　In recent years, sustainability and eco-conscious fashion have taken center stage. One of the most popular materials to emerge from this shift is cork, which is being used to create eco-friendly products like cork bags. As more consumers look for sustainable alternatives, cork bags are becoming a sought-after replacement for traditional leather bags.

　　The mold steel material used in mold parts processing has high hardness, and the mold processing equipment is required to have thermal stability and high reliability.know plastic moulding parts The market will definitely bring great influence to the whole industry. https://www.dghrjmmj.com

　　For complex cavities and multifunctional composite molds, as the shape of the parts becomes more complicated, the design and manufacturing level of the mold must be improved. Multifunctional composite molds that form or assemble multiple grooves and multiple materials in a set of molds require a large amount of processing programming, high deep hole comprehensive cutting ability and high stability, which increases the difficulty of processing. The processing quality of mold parts includes processing accuracy and surface quality: processing accuracy is the degree of conformity between the three geometric parameters of the actual size, shape, and position of the surface of the part after processing and the ideal geometric parameters required by the drawing; the deviation value between the actual geometric parameters of the part and the ideal geometric parameters is called processing error.

　　Processing accuracy and processing error are both terms for evaluating the geometric parameters of the processing surface. Processing accuracy is measured by tolerance grade. The smaller the grade value, the higher the accuracy; processing error is expressed by numerical value. The larger the numerical value, the greater the error. High processing accuracy means small processing error, and vice versa; the actual parameters obtained by any processing method will not be absolutely accurate. From the function of the part, as long as the processing error is within the tolerance range required by the part drawing, it is considered that the processing accuracy is guaranteed.

　　The quality of a machine depends on the processing quality of the parts and the assembly quality of the machine. The processing quality of the parts includes two parts: processing accuracy and surface quality. Machining accuracy refers to the degree to which the actual geometric parameters (size, shape and position) of the parts after processing are consistent with the ideal geometric parameters. The difference between them is called processing error. The size of the processing error reflects the level of processing accuracy. The larger the error, the lower the processing accuracy, and the smaller the error, the higher the processing accuracy; the main aspects that affect processing accuracy: dimensional accuracy, the degree to which the actual size of the part after processing is consistent with the center of the tolerance zone of the part size.
