Embodiment Construction

[0020] combine figure 1 and image 3 The integrated radiation-shielding lead curtain of the present invention is described. The outer contour shape of the lead curtain is adapted to the longitudinal section shape of the entrance of the inspection channel of the security inspection machine. It is composed of a first part 1 and a second part 2 which are integrated, the first part 1 is an integral structure, and the second part 2 is composed of a number of sheet-like lead curtains 3 closely arranged in sequence along the width direction. In the second part 2, a gap structure 4 is provided at the junction between every two adjacent sheet-shaped lead curtains 3, which is used to prevent the gap between the sheet-shaped lead curtains 3 from extending upward. The cut-off structure 4 can be a through hole, a riveted piece or a hot-pressed piece, etc. The shape of the through hole can be circular, oval or polygonal. The connecting line of the check-stop structure 4 can be arc-shaped...

Abstract

The invention discloses an integrated ray-shielding lead curtain and a manufacturing method thereof, and relates to the technical field of X-ray security inspection machines. Aiming at the problems of large amount of ray leakage and low production efficiency of the lead curtain assembled by lamination on the existing security inspection machine when it is set off. The integrated ray-shielding lead curtain is composed of a first part and a second part which are made into one. The first part is an integral structure, and the second part is composed of several sheet-shaped lead curtains arranged closely in sequence. The manufacturing method: a. uniformly cutting the lead-containing inner layer of the second part of the lead curtain to obtain a plurality of sheet-shaped lead curtains; b. sealing and packaging the lead-containing inner layer obtained through step a with a wrapping layer. The invention is especially suitable for the radiation shielding lead curtain of the security inspection machine and its manufacture.

Description

technical field [0001] The invention relates to the technical field of X-ray security inspection machines, in particular to an integrated ray-shielding lead curtain and a manufacturing method thereof. Background technique [0002] The security inspection machine is an electronic device that sends the inspected baggage into the X-ray inspection channel by means of a conveyor belt to complete the inspection. It is widely used in security inspections of airports, customs, land / sea transportation departments, activities with high security levels and organizations (units). [0003] In order to protect the security staff from radiation hazards, traditional rubber / plastic lead curtains are installed at the entrance / exit of the security inspection machine. Lead curtains consist of a leaded inner layer and a wrapping that seals the inner layer. In the prior art, the lead-containing inner layer is made by dissolving lead powder into rubber or other rubber-plastic materials, or is fo...
