Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically to a conveyor for baggage security checks. Background Technology

[0002] With the rapid development of global transportation industries such as aviation, railways, and highways, passenger traffic and baggage volume are constantly increasing, which puts forward higher requirements for the efficiency and security of baggage security inspection systems. In order to prevent pedestrians from carrying dangerous items in their baggage, baggage usually needs to be placed on the conveyor channel when entering the station, and then baggage is inspected by security inspection equipment.

[0003] For example, Chinese patent CN207473106U, entitled "Security Inspection Machine," published on June 8, 2018, includes a conveyor belt and a security inspection chamber. The security inspection chamber is equipped with a lead curtain to prevent X-ray leakage. The conveyor belt has a limiting member to restrict the position of small, lightweight items. When a heavy object is placed on the conveyor belt, the limiting member can be tilted down. When a small, lightweight item is placed on the conveyor belt, the friction between the item and the belt is less than the force exerted by the lead curtain on the item, preventing it from entering the security inspection chamber. The limiting member fixes the item's position on the conveyor belt, and the lead curtain is less likely to push it, allowing the item to enter the security inspection chamber for inspection, facilitating transportation. When a heavy object is placed on the conveyor belt, the limiting member tilts, reducing its impact on the transport of heavy objects to the security inspection chamber. However, the above-mentioned prior art has the following technical problems:

[0004] Existing security screening machines use belt-mounted limiters to block and support small items during baggage transport. However, these limiters are limited in function, only providing support. They do not cushion baggage in case it collapses. Furthermore, pedestrians also undergo full-body security checks during baggage screening. The machine does not slow down baggage as it enters the screening room, and the baggage may fall before the pedestrian has finished their screening due to the high transport speed.

[0005] Therefore, we propose a baggage security screening conveyor to address the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a baggage security screening conveyor channel to solve the problem mentioned in the background art. Currently available security screening machines use belt-mounted limiters to block small items and provide support, but these limiters are limited in function, only providing support. When baggage collapses on the conveyor channel, they do not provide adequate cushioning. Furthermore, during baggage screening, pedestrians also undergo full-body checks. When baggage enters the machine, it is difficult to slow it down, and the excessively fast conveying speed can cause baggage to fall before the pedestrian's screening is complete.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a baggage security inspection conveyor channel, comprising two supporting side plates and a transmission roller installed between the two supporting side plates. The outer side of the transmission roller is wrapped with a conveyor belt for transporting baggage, and one end of the transmission roller is connected to the output end of a power motor. A gap is formed in the middle of the conveyor belt, and a deceleration resistance plate is provided in the gap in the middle of the conveyor belt. The deceleration resistance plate is fixed on the supporting side plate and is located inside the security inspection instrument. A first elastic rubber block is fixed on the conveyor belt, and a gap for placing security inspection baggage is formed between adjacent first elastic rubber blocks. The first elastic rubber blocks are connected to a second elastic rubber block through a drainage air pipe, and the second elastic rubber block is fixed on a positioning side plate. The positioning side plate is fixed to the side of the conveyor belt, and a compression block is fixed on the supporting side plate for compressing the second elastic rubber block.

[0008] Preferably, the width of the deceleration resistance plate is set between 5cm and 10cm, and the upper surface of the deceleration resistance plate is flush with the surface of the conveyor belt, and the upper surface of the deceleration resistance plate is set as a rough surface.

[0009] By adopting the above technical solution, the contact friction between the deceleration resistance plate and the bottom of the baggage can be increased, thereby decelerating the baggage during the security check process.

[0010] Preferably, multiple first elastic rubber blocks are evenly distributed at equal intervals on the conveyor belt, and each first elastic rubber block is connected to a second elastic rubber block through a drain pipe, and each second elastic rubber block is fixed to the positioning side plate.

[0011] By adopting the above technical solution, the expansion direction of the second elastic block can be limited by fixing the second elastic block to the positioning side plate.

[0012] Preferably, the interiors of both the first and second elastic blocks are hollow, and the airflow inside the first and second elastic blocks can be interconnected through the drainage tube.

[0013] By adopting the above technical solution, when the second elastic rubber block is squeezed, the airflow inside it can enter the interior of the first elastic rubber block through the drainage pipe.

[0014] Preferably, the compression blocks are symmetrically arranged about the central axis of the support side plate, and the symmetrically distributed compression blocks are located on the side of the lead curtain at the entrance and exit of the security inspection instrument.

[0015] By adopting the above technical solution, and by setting the extrusion block on the support side plate, the second elastic rubber block on the side can be extruded when the conveyor belt moves.

[0016] Preferably, a self-cleaning component is provided below the conveyor belt. The self-cleaning component includes a support base plate and a pressure block installed through the side. The pressure block is connected to the support base plate by an auxiliary spring. A first magnetic block is fixed above the bottom of the pressure block. A movable support plate is provided above the first magnetic block. The movable support plate is connected to the support base plate by a return spring. An impact rod is fixed at the upper end of the movable support plate. A second magnetic block is fixed below the impact rod. The upper end of the support base plate is provided with bristles for cleaning the surface of the conveyor belt.

[0017] By adopting the above technical solution, when the conveyor belt is conveying, the bristles on the upper end of the support base plate can clean the impurities attached to the conveyor belt, ensuring the cleanliness of the conveyor belt surface.

[0018] Preferably, the upper end of the pressure block is located on the side of the movement trajectory of the second elastic rubber block on the conveyor belt, and the pressure block forms an elastic telescopic structure through the auxiliary spring and the supporting base plate. The bristles on the upper surface of the supporting base plate are in contact with the conveyor belt in the initial state.

[0019] By adopting the above technical solution, the auxiliary spring can be used to reset and rebound the pressed block after it has moved, and the expansion of the second elastic block can push the pressed block.

[0020] Preferably, the first magnetic block on the pressure block and the second magnetic block on the movable tray have opposite magnetic properties, and the movable tray and the supporting base plate are slidably connected.

[0021] By adopting the above technical solution, when the first magnetic block on the pressure block moves and the second magnetic block on the movable tray approaches each other, the movable tray can move on the support base plate.

[0022] Preferably, the impact rods are evenly distributed at equal intervals on the upper end of the movable support plate, and the upper end of the impact rod is set in an arc shape, and the arc-shaped end of the impact rod is in contact with the bottom of the supporting base plate in the initial state.

[0023] By adopting the above technical solution, the movement of the movable pallet can drive the impact rod to move synchronously, and the movement of the impact rod can collide with the supporting base plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the baggage security inspection conveyor can decelerate the baggage after it enters the security inspection machine, preventing pedestrians from falling before the security inspection is completed due to the excessive speed of the baggage conveyor.

[0025] 1. Equipped with deceleration resistance plates, the baggage can be transported through the conveyor belt. The deceleration resistance plates in the middle of the conveyor belt provide resistance to the deceleration resistance plates inside the security inspection equipment during baggage transport, thereby slowing down the baggage and preventing pedestrians from falling before the baggage is fully inspected due to excessive transport speed.

[0026] 2. A first elastic rubber block is provided. The first elastic rubber block can act as a buffer when the goods collapse by using its own elastic deformation. At the same time, when the conveyor belt is running, it can drive the first elastic rubber block and the second elastic rubber block to move synchronously. After the second elastic rubber block moves, it can be squeezed by the compression block. At this time, the airflow inside the second elastic rubber block enters the interior of the first elastic rubber block through the air guide pipe. The first elastic rubber block expands after being inflated. When small luggage is blocked by the lead curtain during transportation, the expanded first elastic rubber block can provide greater support and resistance for the small luggage, making it easier for the small luggage to pass through the lead curtain for security inspection.

[0027] 3. A support base plate is provided. The brush bristles on the upper end of the support base plate can clean the adhering substances on the surface of the conveyor belt. When the conveyor belt is conveying, the first elastic rubber block on it can be squeezed by the support base plate. At this time, the airflow inside the first elastic rubber block can enter the interior of the second elastic rubber block through the air guide pipe. The expansion of the second elastic rubber block after inflation can push the pressure block to move. After the pressure block moves, the movable tray can drive the impact rod to move up and down reciprocally through the magnetic force. The impact rod moves up and down reciprocally and collides with the support base plate, which can shake off the impurities attached to the brush bristles. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-9Existing security screening machines use belt-mounted limiters to support small items during baggage transport. However, these limiters are limited to support and don't provide adequate cushioning when baggage collapses. Furthermore, pedestrians also undergo full-body security checks during baggage screening. The machine's slowing mechanism makes it difficult to decelerate baggage as it enters the machine, increasing the risk of baggage falling before the pedestrian's check is complete. To address this issue... To address this technical problem, this embodiment discloses the following technical content: a baggage security inspection conveyor channel, including two supporting side plates 1 and a transmission roller 2 installed between the two supporting side plates 1. A conveyor belt 3 for transporting baggage is wrapped around the outside of the transmission roller 2, and one end of the transmission roller 2 is connected to the output end of a power motor 4. A gap is formed in the middle of the conveyor belt 3, and a deceleration resistance plate 5 is provided in the gap. The deceleration resistance plate 5 is fixed on the supporting side plate 1 and located inside the security inspection instrument. A [missing information - likely a device or component] is fixed on the conveyor belt 3. The first elastic rubber block 6 forms a gap for placing security baggage between adjacent first elastic rubber blocks 6. The first elastic rubber blocks 6 are connected to the second elastic rubber block 8 through the air drainage pipe 7, and the second elastic rubber block 8 is fixed on the positioning side plate 9, which is fixed to the side of the conveyor belt 3. The support side plate 1 is fixed with a compression stop 10 for compressing the second elastic rubber block 8. The width of the deceleration resistance plate 5 is set between 5cm and 10cm, and the upper surface of the deceleration resistance plate 5 is flush with the surface of the conveyor belt 3. The upper surface of the deceleration resistance plate 5 is set as a rough surface. Multiple first elastic rubber blocks 6 are evenly distributed at equal intervals on the conveyor belt 3, and each first elastic rubber block 6 is connected to a second elastic rubber block 8 through a drainage air pipe 7. Each second elastic rubber block 8 is fixed on the positioning side plate 9. The interior of the first elastic rubber block 6 and the second elastic rubber block 8 are both 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 side of the lead curtain at the entrance and exit of the security inspection instrument.

[0040] When baggage needs to be inspected, it is placed in the gap between the first elastic rubber blocks 6 adjacent to the conveyor belt 3. The first elastic rubber blocks 6 cushion the baggage in the event of a collapse. The drive motor 4 controls the transmission roller 2 to drive the conveyor belt 3, which in turn transports the baggage for inspection. The movement of the conveyor belt 3 synchronizes the movement of the first elastic rubber blocks 6 and the second elastic rubber blocks 8. When the second elastic rubber block 8 is squeezed by the compression block 10, the airflow inside the second elastic rubber block 8 enters the interior of the first elastic rubber block 6 through the air duct 7, causing it to expand. At this time, small items... After the luggage is blocked by the lead curtain inside the security scanner, the expanded first elastic rubber block 6 provides greater support and resistance, allowing smaller luggage to enter the scanner more easily. Once inside the scanner, the bottom of the luggage contacts the deceleration resistance plate 5, which provides resistance to movement and slows down the luggage. This prevents the luggage from falling before the security check is completed due to excessive speed. In the initial state, the first elastic rubber block 6 has a moderate amount of air to avoid overfilling it with air, which would prevent insufficient cushioning when it collides with falling luggage.

[0041] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. The technical content disclosed in this example is as follows: A self-cleaning component 11 is provided below the conveyor belt 3. 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. A first magnetic block 114 is fixed above the bottom of the pressure block 112. A movable support plate 115 is provided above the first magnetic block 114. The movable support plate 115 is connected to the supporting base plate 111 through a reset spring 116. An impact rod 117 is fixed at the upper end of the movable support plate 115. A second magnetic block 118 is fixed below the impact rod 117. The upper end of the supporting base plate 111 is provided with bristles for cleaning the surface of the conveyor belt 3. The upper end of the pressure block 112 is located on the side of the movement trajectory 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 tray 115 have opposite magnetic properties. The movable tray 115 and the supporting base plate 111 are slidably connected. The impact rods 117 are evenly distributed at equal intervals on the upper end of the movable tray 115, and the upper end of the impact rods 117 is set as an arc. The arc end of the impact rods 117 is in contact with the bottom of the supporting base plate 111 in the initial state.

[0042] When the conveyor belt 3 operates, it drives the first elastic rubber block 6 and the second elastic rubber block 8 to operate synchronously. The bristles on the support base plate 111 at the bottom of the conveyor belt 3 can clean the impurities attached to the belt surface. When the conveyor belt 3 drives the first elastic rubber block 6 to move downward and contact the support base plate 111, the first elastic rubber block 6 can be squeezed by the support base plate 111. After the support base plate 111 is compressed, the airflow inside can enter the interior of the second elastic rubber block 8 through the air guide pipe 7. At this time, the second elastic rubber block 8 corresponding to the first elastic rubber block 6 compressed by the support base plate 111 expands, which can push the pressure block 112 on the support base plate 111 to move. When the pressure block 112 moves, it can cause the first magnetic block 114 on it to move synchronously. After the pressure block 112 moves, the first magnetic block 114 on it moves synchronously. When the second magnetic block 118 on the movable tray 115 approaches each other, the magnetic attraction between the first magnetic block 114 and the second magnetic block 118 can make the movable tray 115 move downward. When the conveyor belt 3 continues to run, causing the first elastic rubber block 6 to separate from the supporting base plate 111, the first elastic rubber block 6 and the second elastic rubber block 8 reset themselves through their own elasticity. The pressure block 112 also resets under the action of the auxiliary spring 113. After the pressure block 112 resets, the first magnetic block 114 and the second magnetic block 118 move away from each other, and the movable tray 115 resets and rebounds through the reset spring 116. Thus, the reciprocating movement of the movable tray 115 and the impact rod 117 is realized. By impacting the supporting base plate 111 through the reciprocating movement of the impact rod 117, the impurities attached to the brush bristles can be shaken off by the vibration generated by the impact.
