Abstract

The invention provides an overturning device used on a transportation line under the irradiation of an electron beam which consists of two rotary shafts rotatably arranged in parallel on a frame and two overturning retarding motors fixed on the frame. The two ends of each rotary shaft are fixedly provided with a pair of tumblers. The two pairs of tumblers on two rotary shafts have same structures which consist of a middle body and four overturning arms fixed that is combined with the middle body to be a whole or fixed on the middle body and the axle wires of the four overturning arms are all uniformly arranged on the tangent direction of a same circumference. The corresponding overturning arms of the tumblers on the two rotary shafts are arranged mutually parallel and overlapped. The invention has simple structure, can adopt 90 DEG overturning for twice, shorts one time of the working period and improves the working efficiency and simultaneously ensures reliable transportation.

Description

technical field [0001] The invention relates to an overturning device, in particular to an overturning device used on a conveying line under electron beam irradiation. Background technique [0002] At present, the commonly used security inspection system adopts the form of electron beam irradiation. When electron beams are used to irradiate items with packaging boxes, due to the weak penetrating power of electron beams, the irradiation dose of single-sided irradiation on the upper and lower sides of the object is very uneven. In order to improve its uniformity, it is often necessary to irradiate the object both sides. At this time, it is necessary to turn the packing box 180° after irradiating one side on the conveyor line, and irradiate the other side of the object. The structure of the existing turning device comprises a turning frame, a turning mechanism, a hydraulic or pneumatic pressing mechanism, a hydraulic or pneumatic pushing mechanism, etc., and the structure is ...
