Description

Technical Field

[0001] The present invention relates to the technical field of conveying channels, in particular to a conveying channel for luggage security inspection. Background Art

[0002] With the rapid development of global aviation, railways, highways and other transportation industries, the passenger flow and luggage volume continue to rise, which puts higher requirements on the efficiency and safety of the baggage security inspection system. In order to prevent pedestrians from carrying dangerous goods in their luggage, they usually need to place the luggage on the conveyor channel when entering the station, and then use the security scanner to conduct luggage security inspection.

[0003] For example, the Chinese patent with announcement number: CN207473106U, patent name: security inspection machine, and announcement date: 2018-06-08, includes a conveyor belt and a security inspection room. The security inspection room is provided with a lead curtain to prevent X-ray leakage. The conveyor belt is provided with a limiter for limiting the position of light and small items on the conveyor belt, and the limiter can be overwhelmed when a heavy object is placed on the conveyor belt. When light and small items are placed on the conveyor belt, the friction between the light and small items and the conveyor belt is less than the force of the lead curtain acting on the light and small items, so that the light and small items cannot enter the security inspection room. At this time, the limiter fixes the position of the light and small items on the conveyor belt, and the lead curtain is not easy to push the light and small items, so that the light and small items can enter the security inspection room for security inspection, which is convenient for transportation; when a heavy object is placed on the conveyor belt, the limiter falls over, reducing the influence of the limiter on the transportation of the heavy object to the security inspection room. The above-mentioned prior art has the following technical problems: When the conveying channel of the existing security inspection machine is conveying luggage, the limiter on the belt is used to block the small luggage and provide support for the small luggage. However, the limiter has a single function and can only play a supporting role. When the luggage on the conveying channel collapses, it is not convenient to play a buffering role for the luggage. At the same time, during the luggage inspection, pedestrians also need to undergo full-body inspection. When the luggage enters the interior of the security inspection machine for inspection, it is not convenient to slow down the luggage. The luggage is easily dropped before the pedestrians have completed the inspection due to the excessively fast conveying speed during the luggage inspection.

[0004] Therefore, we propose a conveying channel for luggage security inspection to solve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide a conveying channel for luggage security inspection, so as to solve the problem raised in the above background technology that the conveying channel of the existing security inspection machine on the market is used to block the small luggage through the limiter on the belt when conveying the luggage, so as to provide support force for the small luggage.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: Please refer to Figure 1-Figure 9When the conveying channel of the existing security inspection machine is conveying luggage, the limiter on the belt is used to block the small luggage and provide support for the small luggage. However, the limiter has a single function and can only play a supporting role. When the luggage on the conveying channel collapses, it is not convenient to play a buffering role for the luggage. At the same time, pedestrians also need to undergo full-body security inspection during luggage inspection. When the luggage enters the interior of the security inspection machine for security inspection, it is not convenient to slow down the luggage. It is easy for the luggage to fall before the pedestrians have completed the security inspection due to the excessively fast conveying speed during the luggage inspection. To solve this technical problem, the following technical contents are disclosed in this embodiment: a conveying channel for baggage security inspection, comprising two supporting side plates 1 and a driving roller 2 installed between the two supporting side plates 1, the outer side of the driving roller 2 is wrapped with a conveying belt 3 for conveying baggage, and the end of one of the driving rollers 2 is connected to the output end of the power motor 4, a neutral space is formed in the middle of the conveying belt 3, and a deceleration resistance plate 5 is arranged in the neutral space in the middle of the conveying belt 3, the deceleration resistance plate 5 is fixed on the supporting side plates 1, and the deceleration resistance plate 5 is located on the inner side of the security inspection instrument, and the conveying belt 3 is fixed with A first elastic rubber block 6 is provided, and a gap for placing security check luggage is formed between adjacent first elastic rubber blocks 6. The first elastic rubber block 6 is connected to the second elastic rubber block 8 through a drainage air pipe 7, and the second elastic rubber block 8 is fixed to a positioning side plate 9, and the positioning side plate 9 is fixed to the side of the conveyor belt 3. An extrusion block 10 is fixed to the supporting side plate 1 for extruding the second elastic rubber block 8. The width of the deceleration resistance plate 5 is set to be between 5cm and 10cm, and the upper surface of the deceleration resistance plate 5 is flush with the surface of the conveyor belt 3, and the upper surface of the deceleration resistance plate 5 is set to be a rough surface. There are multiple first elastic rubber blocks 6 evenly distributed on the conveyor belt 3 at equal intervals, and each first elastic rubber block 6 is connected to the second elastic rubber block 8 through a drainage air pipe 7, and each second elastic rubber block 8 is fixed on the positioning side plate 9. The interiors of the first elastic rubber block 6 and the second elastic rubber block 8 are both set to hollow structures, and the airflow inside the first elastic rubber block 6 and the second elastic rubber block 8 can communicate with each other through the drainage air pipe 7. The extrusion blocks 10 are symmetrically arranged about the central axis of the supporting side plate 1, and the symmetrically distributed extrusion blocks 10 are located on the lead curtain side of the inlet and outlet of the security inspection instrument.

[0028] When the luggage needs to be inspected, the luggage is placed in the gap formed between the adjacent first elastic rubber blocks 6 of the conveyor belt 3. The first elastic rubber block 6 can buffer the collapsed luggage when it collapses. The transmission roller 2 is controlled by the power motor 4 to drive the conveyor belt 3 to operate, and the conveyor belt 3 can drive the inspected luggage to be transported during transportation. After the conveyor belt 3 moves, the first elastic rubber block 6 and the second elastic rubber block 8 can operate synchronously. When the second elastic rubber block 8 is squeezed by the extrusion block 10, the airflow inside the second elastic rubber block 8 can enter the first elastic rubber block 6 through the drainage air pipe 7 to expand it. At this time, the small items After the luggage enters the security scanner and is blocked by the lead curtain, the expanded first elastic rubber block 6 can provide greater support resistance to the luggage, so that the small luggage can enter the security scanner better. After the luggage enters the security scanner, the bottom of the luggage contacts the deceleration resistance plate 5, and the deceleration resistance plate 5 can provide movement resistance to the luggage, thereby achieving deceleration of the luggage to prevent pedestrians from falling before the security inspection is completed due to the excessively fast conveying speed of the luggage security inspection room. In the initial state, the air volume inside the first elastic rubber block 6 is moderate, so as to avoid directly filling the first elastic rubber block 6 with too much air volume, which will not provide more elastic buffering when it collides with the collapsed luggage later.

[0029] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. This embodiment discloses the following technical content: a self-cleaning component 11 is arranged below the conveyor belt 3, and the self-cleaning component 11 includes a supporting base plate 111 and a pressure block 112 installed through the side, the pressure block 112 is connected to the supporting base plate 111 through an auxiliary spring 113, and a first magnetic block 114 is fixed above the bottom of the pressure block 112, a movable support plate 115 is arranged above the first magnetic block 114, and the movable support plate 115 is connected to the supporting base plate 111 through a reset spring 116, an impact rod 117 is fixed to the upper end of the movable support plate 115, and a second magnetic block 118 is fixed below the impact rod 117, and a brush for cleaning the surface of the conveyor belt 3 is arranged on the upper end of the supporting base plate 111. The upper end of the pressure block 112 is located on the side of the moving track of the second elastic rubber block 8 on the conveyor belt 3, and the pressure block 112 forms an elastic telescopic structure through the auxiliary spring 113 and the supporting base plate 111. The bristles on the upper surface of the supporting base plate 111 are in contact with the conveyor belt 3 in the initial state. The first magnetic block 114 on the pressure block 112 and the second magnetic block 118 on the movable support plate 115 have opposite magnetic properties, and the movable support plate 115 and the supporting base plate 111 are slidably connected. The impact rod 117 is evenly distributed at equal intervals on the upper end of the movable support plate 115, and the upper end of the impact rod 117 is set to an arc shape, and the arc end of the impact rod 117 is in contact with the bottom of the supporting base plate 111 in the initial state.

[0030] When the conveyor belt 3 is running, it can drive the first elastic rubber block 6 and the second elastic rubber block 8 to run synchronously, and the impurities attached to the surface of the belt can be cleaned by the bristles on the supporting substrate 111 at the bottom of the conveyor belt 3. When the conveyor belt 3 drives the first elastic rubber block 6 to move downward and contact the supporting substrate 111, the first elastic rubber block 6 can be squeezed by the supporting substrate 111. After the supporting substrate 111 is compressed, the internal airflow can enter the second elastic rubber block 8 through the drainage air pipe 7. At this time, the second elastic rubber block 8 corresponding to the first elastic rubber block 6 squeezed by the supporting substrate 111 expands to push the compressed block 112 on the supporting substrate 111 to move. When the compressed block 112 moves, the first magnetic block 114 on it can move synchronously. After the compressed block 112 moves, the first magnetic block 114 When the second magnetic block 118 on the movable support plate 115 approaches each other, the magnetic attraction between the first magnetic block 114 and the second magnetic block 118 can make the movable support plate 115 move downward. When the conveyor belt 3 continues to operate and the first elastic rubber block 6 is separated from the supporting base plate 111, the first elastic rubber block 6 and the second elastic rubber block 8 are reset by their own elasticity, and the compressed block 112 is also reset under the action of the auxiliary spring 113. After the compressed block 112 is reset, the first magnetic block 114 and the second magnetic block 118 move away from each other, and the movable support plate 115 is reset and rebounded by the reset spring 116, thereby realizing the reciprocating movement of the movable support plate 115 and the impact rod 117. The impact of the reciprocating movement of the impact rod 117 on the supporting base plate 111 can use the vibration generated by the impact to shake off the impurities attached to the bristles.
