[0048] The device is mainly applied to the detection of packaged products. The weighing conveying mechanism 2 and the buffer conveying mechanism 1 are arranged at intervals, so that the X-ray can pass through the gap without penetrating the conveying belt, the absorption of the ray is reduced, and the packaging edge of the product to be tested can be better imaged and detected.

[0049] Specifically, referring to the drawings Figure 1 The buffer conveying belt 12 comprises a first buffer conveying section 121 located on the side close to the weighing conveying belt 22. The weighing conveying belt 22 comprises a first weighing conveying section 221 located on the side close to the buffer conveying belt 1. The first buffer conveying section 121 and the first weighing conveying section 221 are arranged at a preset angle, so that the first buffer conveying section 121 and the first weighing conveying section 221 form a mounting space in which at least part of the structure of the image detection mechanism 3 is located.

[0050] Further, the buffer conveying belt 12 further comprises a second buffer conveying section 122 and a third buffer conveying section 123. The first buffer conveying section 121, the second buffer conveying section 122 and the third buffer conveying section 123 are sequentially connected end to end.

The third buffer conveying section 123 is arranged on the buffer conveying table 11.

[0051] The weighing conveying belt 22 further comprises a second weighing conveying section 222 and a third weighing conveying section 223, the first weighing conveying section 221, the second weighing conveying section 222 and the third weighing conveying section 223 are sequentially connected end to end, the first weighing conveying section 221 and the second weighing conveying section 222 are both arranged obliquely, the second driving member 23 is arranged below the weighing conveying table 21 and located at the connection between the first weighing conveying section 221 and the second weighing conveying section 222, and the third weighing conveying section 223 is arranged on the weighing conveying table 21.

[0052] The image detection mechanism 3 comprises a detection box 31 and a ray source 32, the detection box 31 and the ray source 32 are respectively connected with the control mechanism 4, the detection box 31 is arranged in the installation space, and the ray source 32 is located above the gap between the buffer conveying mechanism 1 and the weighing conveying mechanism 2. Among them, the first buffer conveying section 121 and the first weighing conveying section 221 are both arranged obliquely, the detection box 31 has an upper-thin lower-thick structure, the photosensitive element of the detection box 31 is arranged at the upper end of the detection box 31, and the auxiliary element of the detection box 31 is arranged at the lower end of the detection box 31.

[0053] In the prior art, the X-ray of the image detection mechanism 3 can pass through the conveying belt, so that the X-ray is attenuated, the image noise is increased, and the signal-to-noise ratio is reduced, at this time, the accuracy of foreign matter detection and sealing detection can be reduced; the device can support the image detection mechanism 3 between the weighing conveying mechanism and the buffer conveying mechanism, the X-ray does not need to pass through the conveying belt, and therefore the image signal-to-noise ratio can be improved to a certain extent.

[0054] Because the shaft diameter of the conventional conveying mechanism is much larger than the thickness of the conveying belt, even if a knife-edge shaft is used, due to structural problems, the space below the weighing conveying mechanism and the buffer conveying mechanism is limited, and the conventional X-ray detection box is flat and cannot be directly placed in the gap between the weighing conveying mechanism and the buffer conveying mechanism, so the distance between the detection box 31 and the product to be detected is large, at this time, the image quality is also poor. According to the principle of X-ray imaging, the closer the detection box 31 is to the object to be detected and the closer it is to the X-ray source, the better the image quality is. Therefore, the shape structure of the detection box 31 is designed, a knife-edge detection box is designed, the detection box 31 is arranged in an upper-thin lower-thick structure and is roughly in the shape of a convex character and a trapezoid (or a similar shape), the photosensitive element is arranged at the top thin position of the trapezoidal detection box, and other elements are arranged at the bottom thick position of the trapezoidal detection box, and the other elements are vertically arranged, so that the horizontal size of the detection box can be better reduced; the photosensitive area of the detection box can be closer to the product to be detected, and the image quality can be improved.

In the working state, the control mechanism 4 receives the image sent by the image detection mechanism 3 and judges whether the product in the image is qualified, and receives the weighing result sent by the weighing conveying mechanism 2, then processes the X-ray image result and the weight result, and finally obtains the product detection result. According to the result, a signal is sent to control the destination of the product. Qualified products will enter the subsequent process of the production line, and unqualified products will be rejected.

[0058] Further, the multifunctional X-ray detection device further comprises a rejection mechanism and a collection box.
