Embodiment 1

[0048] Such as figure 1 As shown, this embodiment discloses a differential conveyor security inspection system, which includes a security inspection machine 100 and a power transmission device 200. The security inspection machine 100 includes a detector 110 and a belt conveyor 120. The detector 110 is arranged on the belt conveyor 120. , To detect the luggage parcels conveyed by the belt conveyor 120. The power transmission device 200 is docked at the entrance of the belt conveyor 120. The transmission plane of the power transmission device 200 and the transmission plane of the belt conveyor 120 are on the same level. The transmission direction of the power transmission device 200 and the belt conveyor 120 are the same, and the power transmission The conveyor line speed of the conveyor 200 is lower than the conveyor line speed of the belt conveyor 120. The baggage parcels are conveyed to the belt conveyor 120 through the power transmission device 200, and the belt conveyor 120 q...

Embodiment 2

[0054] This embodiment also discloses a differential conveyor security inspection system. This embodiment is a further improvement on the basis of the above embodiment 1. The main difference from the embodiment 1 is that this embodiment further improves the belt conveyor 120 and the structure of the power transmission device 200. Because the applicant found in the process of using the differential conveyor security inspection system of the first embodiment, if the existing belt conveyor or power transmission device is directly used for assembly and use, there are some shortcomings: manual frequent debugging is required to ensure the belt during production and installation. The tension and position of the belt are correct; after delivery to the customer, the belt will be loose after long-term use and the belt will shift to the correct position due to the impact of the belt, which will cause the belt conveyor to slip and reduce its life. It requires regular after-sales maintenance...

Embodiment 3

[0069] This embodiment also discloses a differential conveyor security inspection system. This embodiment is a further improvement on the basis of the above embodiment 1, to solve the application of the existing belt conveyor or power transmission device to the differential conveyor security inspection system There are some shortcomings: the existing belt conveyors and power transmission devices will cause the belt lateral deviation during long-term operation due to its own aging and unilateral conveying conditions, that is, left and right swings, which can seriously cause belt damage. Therefore, the applicant has made further improvements. Several automatic belt deviation adjustment devices 400 are added to the security inspection system. An automatic belt deviation adjustment device 400 is installed below the belt position that needs to be adjusted to correct the inclination of the roller 410. Set under the belt to effectively correct the lateral inclination deviation, prevent...

Abstract

The invention discloses a differential conveying security check system which comprises a security check machine and a power conveying device. The power conveying device is in butt joint with the inlet of a belt conveyor. The power conveying device and the belt conveyor are located on the same horizontal plane and identical in conveying direction. The conveying linear speed of the power conveying device is smaller than that of the belt conveyor. Luggage parcels are conveyed to the belt conveyor through the power conveying device. The belt conveyor quickly increases the distances between the adjacent luggage parcels. The differential conveying security check system can quickly increase the distances between the luggage parcels which are compactly stacked in the prior art, and the luggage parcels enter a detector as a queue at certain intervals one by one, so that the defect that in the conveying process of an existing security check machine, luggage parcels are stacked is overcome, image uniformity of luggage parcels which pass through the security check machine each time is guaranteed, the check leakage phenomenon is effectively avoided, and the abnormal luggage parcels can be conveniently checked.

Description

Technical field [0001] The invention relates to the technical field of security inspection equipment design, in particular to a differential conveying security inspection system. Background technique [0002] The security inspection machine is an electronic device that uses a belt conveyor to send the checked luggage into the X-ray inspection channel to complete the inspection. At present, the common security inspection machines on the market are mainly used in important places such as railway stations, bus stations, airports, customs, ports, logistics, warehouses, etc., to detect luggage and parcels, large and medium-sized luggage, suitcases, checked items and other larger items. The applicant found that the existing security inspection machines often encounter the following two situations when performing routine security inspections: 1. There are many luggage packages, which cause accumulation during transportation; 2. The piled luggage packages flood into the detection channel...
