In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] The security inspection equipment disclosed by the utility model is described below in conjunction with the accompanying drawings. Figure 1As shown, it includes a security inspection machine 100 and a first conveyor 200 passing through the security inspection machine 100. The specific structure of the security inspection machine 100 is a known technology and is not described here. The first conveyor 200 can be a known feasible conveying device, preferably a belt conveyor.

[0030] The output end of the first conveyor 200 is connected to the second conveyor 300. The second conveyor 300 is also preferably a belt conveyor. The main function of the second conveyor 300 is to buffer luggage and keep the distance between luggage. Its length can be selected according to needs, preferably not less than 1m. The specific length can be adjusted according to the actual site needs and is not limited here. When abnormal luggage enters the second conveyor 300, the second conveyor 300 accelerates, and when abnormal luggage is output from the second conveyor 300, the second conveyor 300 decelerates. In order to prevent the belt from running off when the belt conveyor accelerates or decelerates suddenly, the inner wall of the belt of the second conveyor 300 is provided with limit strips close to its two sides, and the belt support plate of the second conveyor 300 is provided with two limit grooves matching the limit strips.

[0031] As attached Figure 1 As shown, the output end of the second conveyor 300 is connected to the oscillating wheel sorter 400. The oscillating wheel sorter 400 may be a known feasible device, for example, it may be the structure disclosed in the utility model patent with the authorization announcement number CN215744872U, which will not be described here. The first output side of the oscillating wheel sorter 400 is connected to the first storage slot 500, and the second output side of the oscillating wheel sorter 400 is connected to the second storage slot 600. A display 700 is provided on the side of the security inspection machine 100, the first storage slot 500 and the display 700 are located on the same side of the oscillating wheel sorter 400, and the second storage slot 600 and the second conveyor 300 are located on both sides of the oscillating wheel sorter 400. This can greatly facilitate the security personnel to check abnormal packages without affecting the normal passage of passengers.

[0032] As attached Figure 1As shown, in order to better control the conveyance of luggage, the security inspection machine 100 is provided with an image acquisition device 800, which can be a feasible device such as a camera or a webcam. The image acquisition device 800 is installed on the top of the chassis of the security inspection machine 100 through a mounting frame, and the lens of the image acquisition device 800 extends toward the first conveyor 200 to the part outside the delivery port of the security inspection machine 100. The balance wheel sorting machine 400 includes multiple sorting areas. Preferably, the balance wheel sorting machine 400 includes three sorting areas, each of which can include one or more rows of balance wheel sorting units, and the balance wheels of the balance wheel sorting units swing simultaneously to achieve sorting, and the swing angles of the balance wheels of the three sorting areas increase from upstream to downstream, that is, the swing angles of the balance wheels of the three sorting areas can be set to 30°, 60°, and 90° respectively. During operation, the position of the abnormal baggage in the width direction of the second conveyor line is determined based on the image captured by the image acquisition device 800, so as to control the three sorting areas to adopt different conveying speeds to make the baggage more flexible to enter the second storage tank 600. At the same time, polyurethane coating is added to the surface of the balance wheel to protect the surface of the baggage.

[0033] As attached Figure 2As shown, since luggage often has various small and soft parts, it is easy to get stuck in the gap and cannot be transported normally. Therefore, an anti-stuck device 900 is provided between the first conveyor 200 and the second conveyor 300 and / or between the second conveyor 300 and the swing wheel sorter 400. In addition, the height of the conveying surface of the first conveyor 200 is higher than the height of the conveying surface of the second conveyor, and the height of the conveying surface of the second conveyor is higher than the height of the conveying surface of the swing wheel sorter. The anti-stuck device 900 includes a fixed plate 910, and a scraper 920 is provided on the fixed plate 910. The top of the scraper 920 is provided with wear-resistant bristles 930. The fixed plate 910 can adjust the installation position along the conveying direction of the first conveyor 200, and the scraper 920 can adjust the installation position along the vertical direction. Taking the adjustment of the anti-stuck device 900 between the first conveyor 200 and the second conveyor 300 as an example, the fixed plate 910 is L-shaped and fixed at the side plate of the second conveyor 300. One of the fixed plate 910 and the side plate of the second conveyor 300 is formed with a strip hole extending in the conveying direction of the second conveyor 300, and the other is formed with a through hole matching the strip hole. After adjusting the corresponding positions of the through hole and the strip hole, the fixed plate 910 and the side plate are locked by bolts and nuts to achieve the position adjustment of the fixed plate 910. One of the scraper 920 and the fixed plate 910 is formed with a waist hole extending in the vertical direction, and the other is provided with a connecting hole matching the waist hole. After adjusting the corresponding positions of the connecting hole and the waist hole, the scraper 920 and the fixed plate 910 are locked by bolts and nuts to achieve the installation height adjustment of the scraper 920, so as to better meet the conveying requirements.

[0034] The first storage slot 500 and / or the second storage slot 600 have the same structure. The second storage slot is taken as an example for description. Figure 3 As shown, the bottom plate of the second storage slot includes an inclined plate 610 and a horizontal plate 620, and side guards 630 are provided on the three sides of the bottom plate that are not connected to the swing wheel sorter 400. The closed structure can better store the luggage and facilitate passengers to take the luggage.

[0035] As attached Figure 3 , Attachment Figure 4 As shown, in order to make the luggage enter the storage slot and the second storage slot 600 more smoothly, a roller 640 is provided at the upper end of the first storage slot 500 and the second storage slot 600, and the roller 640 is a non-powered roller. At the same time, a disassembly notch 650 for installing the roller 640 is provided at the beam side stop 630 of the first storage slot 500 and the second storage slot 600. When there is a stuck cargo that needs to be repaired, the roller 640 can be quickly disassembled and assembled through the disassembly notch 650.

[0036] When the whole sorting equipment is working, the control device controls the first conveyor 200 to convey, and detects whether the luggage is abnormal when the luggage moves through the security inspection machine 100. When it is determined that there is an abnormal piece, the image acquisition device 800 is controlled to acquire the image of the abnormal luggage and determine its position on the second conveyor line according to the conveying speed of the first conveyor 200, the shape of the abnormal luggage and other data, and then determines the conveying speed and swing angle of each sorting area of ​​the swing wheel sorter 400, and at the same time displays the image of the luggage through the display 700 and the alarm light is turned on through the indicator light.

[0037] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
