Description

Improved X-ray detector Technical Field The utility model relates to the field of physics, in particular to a metal detection technology, and especially relates to an improved X-ray detector. Background The X-ray detector accelerates electron beams to strike a metal target (such as a tungsten target) through a high-voltage electric field to generate high-energy X-rays, when the X-rays penetrate through an object to be detected, the absorption degree is different due to the density, thickness and composition difference of materials, and the non-absorbed rays are projected onto a detector, converted into electric signals and generated into digital images so as to identify the problems of foreign matters or defects in the product. In the prior art, the ray radiation protection of the X-ray detector is usually protected by shielding by a lead curtain, and in order to avoid the leakage of X-rays, the gap between the lead curtain and a conveying belt is usually very small. Such an X-ray detector of the prior art has the following problems: 1. In order to prevent radiation from leaking, the gap between the lead curtain and the conveyor belt is very small, the lead curtain contains lead, sags and has a certain weight, and for light detection objects (such as clothes and the like), the detection objects can be blocked by the lead curtain in the conveying process and cannot be effectively conveyed, and if the gap between the lead curtain and the conveyor belt is too large, X-rays can leak. 2. Sometimes, according to the wiring position requirement, the conveying directions of the X-ray detector are required to be exchanged, but after the exchange, the channel components of the inlet and the outlet are different in structure, so that the material to be detected can not be conveyed. Disclosure of utility model The utility model aims to provide an improved X-ray detector, and the structure of an access passage of the X-ray detector aims to solve the technical problems that in the prior art, a light object is blocked due to too small gap between a lead curtain and a conveyor belt, and X-rays are possibly leaked due to too large gap between the lead curtain and the conveyor belt. An improved X-ray detector comprises a detector body, wherein a detection channel penetrating front and back is arranged in the detector body, a transmission belt is arranged in the detection channel, the detector comprises an inlet component and an outlet component, the inlet component is arranged at the inlet of the detection channel, the outlet component is arranged at the outlet of the detection channel, a first slope channel penetrating front and back is arranged in the inlet component, the height of the inlet of the first slope channel from the ground is higher than the height of the outlet of the first slope channel from the ground, the outlet of the first slope channel is communicated with the inlet of the detection channel, a first sliding plate is paved at the bottom in the first slope channel, the outlet end of the first sliding plate is positioned above the inlet end of the transmission belt, a second shielding curtain is arranged at the inlet of the first slope channel, a second slope channel penetrating front and back is arranged in the outlet component, the height of the inlet of the second slope channel is higher than the height of the outlet from the ground, the outlet of the first slope channel is communicated with the inlet of the second slope channel, a second sliding plate is arranged at the bottom of the second slope channel, and the second sliding plate is arranged at the bottom of the second slope channel.
