Description

Technical Field

[0001] This utility model relates to the field of cargo transportation technology, and in particular to a customs inspection cargo transportation and guiding device. Background Technology

[0002] In customs inspection, efficient and safe transport of goods is crucial for ensuring the smooth progress of the inspection process. Currently, roller conveyors are widely used as the primary transport equipment for customs inspections. These conveyors achieve automated or semi-automated transport of goods through the rotation of rollers, effectively reducing manual handling costs and improving cargo transfer efficiency. They are widely used in various import and export cargo inspection scenarios. However, in actual use, roller conveyors have certain limitations in transporting goods. Due to the wide variety of goods, their different sizes and shapes, and factors such as placement misalignment, roller vibration, or external interference during transport, goods may shift or deviate during transport, posing a risk of falling off the conveyor's edge. To address this issue, traditional roller conveyors typically have supports on both sides or ends of the machine to limit the movement of goods and prevent them from falling.

[0003] However, this traditional support system exhibits significant drawbacks in practical applications: firstly, goods are prone to violent impacts when they come into contact with the support during transport. For fragile items (such as glassware and precision instruments) or goods with delicate packaging, such impacts can directly lead to damage, causing economic losses and affecting the normal progress of inspection work; secondly, the contact between goods and the support generates considerable friction, which hinders the smooth movement of goods, increasing the operating load on the roller conveyor and significantly reducing the transport speed, thus affecting overall inspection efficiency. Therefore, this application proposes a customs inspection cargo conveying and guiding device to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a customs inspection cargo conveying and guiding device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A customs inspection cargo conveying and guiding device includes a roller conveyor body. Mounting brackets are fixedly installed at both ends of the roller conveyor body. Each mounting bracket consists of an L-shaped support plate, a support rod, a connecting rod, a hand-tightening bolt, and a support limiting plate. The support rod is fixedly installed on the upper end of the L-shaped support plate. The connecting rod is movably inserted into the support rod. The hand-tightening bolt is installed on the support rod, with one end of the hand-tightening bolt simultaneously abutting against the connecting rod. The support limiting plate is fixedly installed on the inner end of the connecting rod. Several drag-reducing buffer structures are evenly and movably installed on the support limiting plate. Each drag-reducing buffer structure consists of a mounting square rod, a buffer spring, an anti-detachment baffle, a mounting base block, and a contact roller. The buffer spring is sleeved on the mounting square rod. The anti-detachment baffle is fixedly installed on the outer end of the mounting square rod. The mounting base block is fixedly installed on the inner end of the mounting square rod. The contact roller is rotatably installed within the mounting base block.

[0007] Preferably, a number of support legs are fixedly installed at the lower end of the main body of the roller conveyor.

[0008] Preferably, the L-shaped support plate on the mounting bracket is fixedly installed at one end of the roller conveyor body by bolts, and a through hole is provided on the side wall of the support rod to pass through the support rod. A threaded hole is provided at the upper end of the support rod, and the threaded hole and the through hole are interconnected.

[0009] Preferably, the hand-tightening bolt is installed in the threaded hole at the upper end of the support rod, the connecting rod is movably inserted into the through hole on the support rod, and the support limiting plate is provided with a plurality of mounting square holes, which penetrate the support limiting plate inside and out.

[0010] Preferably, the mounting rod on the drag-reducing buffer structure is slidably mounted in the mounting hole opened on the support limiting plate, the anti-detachment baffle is located on the outside of the support limiting plate, and the buffer spring is located on the inside of the support limiting plate.

[0011] Preferably, the inner end of the mounting base block on the drag reduction and buffer structure is provided with a roller receiving groove, and the contact roller is rotatably installed in the roller receiving groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By installing a drag-reducing buffer structure consisting of a mounting square rod, a buffer spring, an anti-detachment baffle, a mounting base block, and a contact roller on an mounting bracket composed of an L-shaped support plate, support rod, connecting rod, hand-tightening bolts, and a support limiting plate, when goods deviate in position during transport on the roller conveyor body and are about to contact the support limiting plate, the contact roller on the drag-reducing buffer structure will replace the support limiting plate in contact with the goods. The rotation of the contact roller transforms the sliding friction between the goods and the support limiting plate into rolling friction between the goods and the contact roller, significantly reducing the frictional resistance of the goods' movement, ensuring smooth transport, reducing the operating load on the roller conveyor body, and improving the transport speed and overall inspection efficiency. Simultaneously, the impact force generated when the goods contact the contact roller causes the mounting square rod to slide within the mounting square hole, and the buffer spring is subsequently compressed by the mounting base block. The elastic deformation of the buffer spring absorbs the impact force, achieving buffer protection for the goods, preventing violent collisions, effectively reducing the risk of damage to fragile or poorly packaged goods, minimizing economic losses, and ensuring the normal operation of inspection work.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a customs inspection cargo conveying and guiding device includes a roller conveyor body 1. Mounting brackets 2 are fixedly installed at both ends of the roller conveyor body 1. Each mounting bracket 2 consists of an L-shaped support plate 5, a support rod 6, a connecting rod 7, a hand-tightening bolt 8, and a support limiting plate 9. The support rod 6 is fixedly installed on the upper end of the L-shaped support plate 5. The connecting rod 7 is movably inserted into the support rod 6. The hand-tightening bolt 8 is installed on the support rod 6, with one end of the hand-tightening bolt 8 simultaneously abutting against the connecting rod 7. The support limiting plate 9 is fixedly installed on the inner end of the connecting rod 7. Several drag-reducing buffer structures 3 are evenly and movably installed on the 9th. Each drag-reducing buffer structure 3 consists of a mounting square rod 11, a buffer spring 12, an anti-detachment baffle 13, a mounting base 14, and a contact roller 16. The buffer spring 12 is sleeved on the mounting square rod 11, the anti-detachment baffle 13 is fixedly installed on the outer end of the mounting square rod 11, the mounting base 14 is fixedly installed on the inner end of the mounting square rod 11, and the contact roller 16 is rotatably installed inside the mounting base 14. The system is connected by a support plate 5, a support rod 6, a connecting rod 7, a hand-tightening bolt 8, and a support limiting plate 9. The mounting bracket 2 is equipped with a drag-reducing buffer structure 3, consisting of a mounting square rod 11, a buffer spring 12, an anti-detachment baffle 13, a mounting base block 14, and a contact roller 16. When the goods are conveyed on the roller conveyor body 1 and their position deviates and they are about to contact the support limiting plate 9, the contact roller 16 on the drag-reducing buffer structure 3 will replace the support limiting plate 9 and contact the goods. With the rotation of the contact roller 16, the sliding friction between the goods and the support limiting plate 9 can be transformed into rolling friction between the goods and the contact roller 16, which greatly reduces the frictional resistance of the goods movement. The force ensures smooth cargo transportation, reduces the operating load of the main body 1 of the roller conveyor, and improves the cargo transportation speed and overall inspection efficiency. At the same time, the impact force generated when the cargo comes into contact with the contact roller 16 will cause the mounting square rod 11 to slide in the mounting square hole 10, and the buffer spring 12 will be compressed by the mounting base block 14. The elastic deformation of the buffer spring 12 absorbs the impact force, thereby achieving buffer protection for the cargo, avoiding violent collisions, effectively reducing the risk of damage to fragile or poorly packaged goods, reducing economic losses, and ensuring the normal operation of inspection work.

[0021] Specifically, several support legs 4 are fixedly installed at the lower end of the roller conveyor body 1. An L-shaped support plate 5 on the mounting bracket 2 is fixedly installed at one end of the roller conveyor body 1 by bolts. A through hole is opened on the side wall of the support rod 6, and a threaded hole is opened at the upper end of the support rod 6. The threaded hole and the through hole are interconnected. A hand-tightening bolt 8 is installed in the threaded hole at the upper end of the support rod 6. A connecting rod 7 is movably inserted into the through hole on the support rod 6. Several mounting square holes 10 are opened on the support limiting plate 9, penetrating both the inside and outside of the support limiting plate 9. A mounting square rod 11 on the drag-reducing buffer structure 3 is slidably installed in the mounting square holes 10 on the support limiting plate 9. An anti-detachment baffle 13 is located on the outside of the support limiting plate 9. A buffer spring 12 is located on the inside of the support limiting plate 9. A roller receiving groove 15 is opened at the inner end of the mounting base block 14 on the drag-reducing buffer structure 3. A contact roller 16 is rotatably installed in the roller receiving groove 15. The spacing between two adjacent drag-reducing buffer structures 3 on the limiting plate 9 needs to be reasonably set according to the actual size and shape of the transported goods. Generally, this spacing should be smaller than the minimum lateral dimension of common goods to ensure that the goods can contact at least one contact roller 16 on the drag-reducing buffer structure 3 when they deviate, thereby ensuring the effective performance of drag reduction and buffering. For example, for general boxed goods, the spacing between two adjacent drag-reducing buffer structures 3 can be set to 10-20 cm, so that the goods can be promptly affected by the drag-reducing buffer structure 3 during the deviating process, avoiding the situation where the edges of the goods do not contact the drag-reducing buffer structure 3 due to excessive spacing and directly hit the supporting limiting plate 9. At the same time, this spacing should not be too small to prevent the drag-reducing buffer structures 3 from being too dense, increasing the load on the supporting limiting plate 9 and the installation difficulty, and to reserve enough space for the deformation of the buffer spring 12, ensuring that each drag-reducing buffer structure 3 does not interfere with each other during operation, and ensuring the stable operation of the overall device.

[0022] When customs inspects and transports goods, the goods are first placed on the main body 1 of the roller conveyor. Then, the main body 1 of the roller conveyor is started. At this time, the rollers on the main body 1 rotate, causing the goods to move along the conveying direction. During the transport of goods, the mounting bracket 2 is fixed to both ends of the main body 1 of the roller conveyor via L-shaped support plates 5. The insertion depth of the connecting rod 7 in the through hole on the support rod 6 can be adjusted by loosening the hand-tightening bolt 8 according to the width of the goods, thereby changing the distance between the two opposing support limit plates 9. After adjustment, the hand-tightening bolt 8 is tightened to fix the connecting rod 7. When deviation occurs during the transport of goods... When the contact roller 16 contacts the drag-reducing buffer structure 3, it first contacts the goods. As the goods move, they drive the contact roller 16 to rotate in the roller receiving groove 15. At the same time, the impact force of the goods on the contact roller 16 causes the mounting base 14 to drive the mounting square rod 11 to slide outward in the mounting square hole 10 of the support limiting plate 9. At this time, the mounting base 14 will compress the buffer spring 12, and the elastic deformation of the buffer spring 12 will absorb the impact force. When the offset of the goods decreases, the buffer spring 12 resets and pushes the mounting square rod 11 and the mounting base 14 to move inward, so that the contact roller 16 continues to contact the goods and play a guiding role.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
