[0030] It should be understood that when one element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element, or there can be an intervening element (e.g., a third element) between the element and the other element.

[0031] The embodiment of the present utility model provides an X-ray detection equipment with a belt anti-displacement device, as shown in Figures 1-6 The embodiment of the present utility model provides an X-ray detection equipment with a belt anti-displacement device, as shown in

[0032] The support frame 100 is used for mounting the belt conveying component, and the support frame 100 comprises two groups of first roller mounting parts 110 arranged horizontally symmetrically left and right, and further comprises two groups of second roller mounting parts 120 arranged horizontally.

[0033] two first rollers 200 are respectively installed on the first roller mounting portions 110;

[0034] two second rollers 300 are respectively installed on the second roller mounting portions 120;

[0035] a detection assembly 400 is provided on the support frame 100, which includes a detection plate 410 with a detection opening 420;

[0036] two limiting assemblies 500 are used to limit the position of the belt, and are fixed on the support frame 100 and respectively abut the edges on both sides of the belt.

[0037] The support frame 100 is used to install the belt conveying components. It includes two groups of first roller mounting portions 110 arranged symmetrically left and right, and two groups of second roller mounting portions 120 arranged horizontally with the two groups of first roller mounting portions 110. Two first rollers 200 are respectively installed on the first roller mounting portions 110. These rollers are used to drive or guide the movement of the belt. Two second rollers 300 are respectively installed on the second roller mounting portions 120. These rollers are used to assist the stable operation of the belt or adjust the tension of the belt. The detection assembly 400 includes a detection plate 410 provided on the support frame 100, and has a detection opening 420. The detection opening 420 is the place where the X-ray detection equipment detects, and the objects on the belt will pass through this detection opening 420. The limiting assembly 500 limits the position of the belt to prevent it from shifting. The limiting assembly 500 is fixed on the support frame 100 and abuts the edges on both sides of the belt, which can ensure that the belt maintains the correct position during conveying. This design uses rollers and limiting assemblies 500 to ensure the stability and accuracy of the belt during X-ray detection, reducing detection errors caused by belt shifting.

[0038] The working principle of the utility model is as follows:

[0039] The belt is conveyed through the cooperation of the first rollers 200 and the second rollers 300. One of the first rollers 200 serves as the driving roller, responsible for driving the movement of the belt, while the other first roller and the two second rollers 300 serve as the driven rollers, assisting the stable operation of the belt and maintaining the tension of the belt. The limiting assembly 500 limits the position of the belt during conveying to prevent it from shifting. These limiting assemblies 500 abut the edges on both sides of the belt, ensuring that the belt always maintains the center position during conveying, so as to ensure that the objects passing through the detection opening 420 can be accurately detected. When the objects pass through the detection opening 420 with the belt, the X-ray machine can detect and analyze the objects passing through the detection opening 420.

[0040] The design of the belt anti-displacement device ensures the stability of the entire device operation, so that the belt will not be displaced during operation due to external factors, thereby ensuring the continuity and accuracy of the detection. The first roller mounting part 110 designed with left-right symmetry helps to maintain the balance of the belt during transportation, reducing the deviation of the belt caused by asymmetry. Through this design, the X-ray detection equipment with the belt anti-displacement device can effectively reduce the displacement of the belt during detection, improve the accuracy and reliability of the detection.

[0041] In some embodiments, the limiting component 500 includes a rotating roller 510 that abuts the edge of the belt.

[0042] The rotating roller 510 in the limiting component 500 is designed to abut the edge of the belt. This design allows the belt to contact the rotating roller 510 during transportation, thereby limiting the lateral movement of the belt and preventing it from deviating from the predetermined transportation path. The material of the rotating roller 510 is selected to be wear-resistant and have a moderate friction coefficient, such as rubber, polyurethane or other engineering plastics, to ensure that the belt can be effectively limited when contacting the rotating roller 510 without causing excessive wear. By using the rotating roller 510 as the limiting component 500, the X-ray detection equipment with the belt anti-displacement device can more effectively control the position of the belt, reduce detection errors caused by belt deviation, and improve the accuracy of detection and the reliability of the equipment. This design also helps to reduce the wear of the belt and prolong its service life.

[0043] Further, the limiting component 500 also includes a fixed part 520 fixed on the support frame 100, and the fixed part 520 is provided with an extension rod 530, and the rotating roller 510 is rotationally connected with the extension rod 530.

[0044] The fixed part 520 is a part of the limiting component 500 and is fixed on the support frame 100. Its function is to provide a stable installation basis for the limiting component 500. The fixed part 520 can be designed in various shapes, such as plates, strips or blocks, to adapt to different support frame 100 structures and installation requirements. The extension rod 530 is an extension of the fixed part 520, and its length and shape can be designed according to actual needs to ensure that the rotating roller 510 can abut the edge of the belt. The extension rod 530 can be adjustable to adjust according to the width and position of the belt, ensuring that the rotating roller 510 always maintains contact with the edge of the belt. The rotating roller 510 and the extension rod 530 are rotationally connected, and this connection allows the rotating roller 510 to rotate freely under the pressure of the belt, reducing friction and wear. The rotating connection can use bearings, shaft sleeves or other mechanical structures that allow rotation to ensure the flexibility and stability of the rotating roller 510.

[0045] In some embodiments, the rotating rollers 510 are inclinedly arranged. The inclinedly arranged rotating rollers 510 means that the rotating rollers 510 are inclinedly abut against the belt. This is conducive to preventing the belt from being deformed under the limiting of the rotating rollers 510.

[0046] In some embodiments, the two groups of second roller mounting portions 120 are arranged below the two groups of first roller mounting portions 110, and the distance between the two groups of second roller mounting portions 120 is less than the distance between the two groups of first roller mounting portions 110.

[0047] Since the second roller mounting portions 120 are located below the first roller mounting portions 110, the belt will experience a downward force when passing through the second rollers 300, which helps to increase the tension of the belt and reduce the sagging and swinging of the belt. The increased tension helps to improve the stability of the belt, especially under high-speed conveying or heavy load conditions.

[0048] Further, the limiting assembly 500 is arranged near one side of the second roller mounting portions 120.

[0049] The limiting assembly 500 is arranged near one side of the second roller mounting portions 120, which can ensure that the belt is correctly aligned when passing through the second rollers 300 on that side.

[0050] Still further, the second roller mounting portions 120 near the side of the limiting assembly 500 are provided with stepped grooves 140 for limiting the second rollers 300.

[0051] The stepped groove 140 is a groove on the second roller mounting portion 120, designed to accommodate the shaft of the second roller 300. The stepped groove 140 is used to limit the movement of the second roller 300 perpendicular to the direction of belt conveying, preventing the roller from deviating during operation. The stepped groove 140 can also provide additional stability, as it can limit the movement of the roller in the horizontal direction, thereby maintaining the tension and alignment of the belt.

[0052] Still further, the second roller mounting portions 120 near the side of the limiting assembly 500 are provided with protrusions 130 for limiting the second rollers 300.

[0053] The protrusion 130 is used to limit the movement of the shaft of the second roller 300 on the second roller mounting portion 120, preventing the second roller 300 from disengaging from the second roller mounting portion 120. The protrusion 130 can be round, square, or other shapes.

[0054] In some embodiments, the detection assembly 400 further includes a sensor rack 430 fixed to the support frame 100, which is used to place the sensor.

[0055] The sensor holder 430 is used to fix and support the sensor. The sensor holder 430 can protect the sensor from the external environment, such as dust, humidity or other factors that may affect the performance of the sensor.

[0056] In some embodiments, the X-ray detection device with a belt anti-displacement device further comprises a driving component 600 for driving the first roller 200, which is fixed on the support frame 100 and connected with the first roller 200 on one side.

[0057] The driving component 600 is a component for transmitting power to the first roller 200, which can be a motor, a gear, a belt or other mechanical transmission devices. By driving the first roller 200, the continuous movement of the belt during the conveying process can be ensured, and the slipping and wear of the belt can be reduced.

[0058] The connection between the driving component 600 and the first roller 200 can be direct, such as through a shaft connection, or indirect, such as through a belt, chain or gear. The choice of connection method depends on the required power transmission efficiency and the maintenance requirements of the device. The driving component 600 is fixed on the support frame 100 to ensure stability and reduce vibration during operation. The fixing method can be bolted, welded or other mechanical fixing methods to ensure the stability of the driving component 600 under high load.

[0059] Further, the limiting component 500 is arranged on the other side away from the driving component 600.

[0060] The limiting component 500 is arranged on the other side away from the driving component 600, so that power and limiting can be provided at both ends of the belt conveying system, enhancing the stability of the belt. This layout helps to reduce the deviation of the belt on the driving side due to uneven power transmission or changes in belt tension. By arranging the limiting component 500 on the opposite side of the driving component 600, uniform support can be provided at both ends of the belt conveying system, achieving better mechanical balance. This balance helps to reduce the vibration and swing of the belt during operation, improving the accuracy of detection.
