Description

Technical Field

[0001] This utility model relates to the field of cargo reweighing technology, specifically a high-precision dynamic reweighing device for air cargo. Background Technology

[0002] In the air cargo sector, the accuracy of cargo weight directly affects flight loading safety and logistics timeliness. If the weight data deviation is too high, it may cause the aircraft's center of gravity to shift, leading to safety hazards. At the same time, the traditional reweighing mode of multi-level air cargo terminals relies on manual weighing and handwritten records, which has problems such as low efficiency, high error rate, and high cost of rework due to abnormalities.

[0003] The device consists of a multi-level hardware system, a data collaboration module, and an intelligent management and control platform. After the container is unloaded, the TV truck transports the goods to the ETV entrance on this floor. The sensors automatically collect the weight and compare it with the pre-weighing data. If the error is below the threshold, the green light is activated to allow passage; if the error exceeds the threshold, the red light is activated to trigger the TV truck to return along the original route. The unloading platform on the first floor retrieves the data from the entire process to complete the final reweighing and synchronizes it with the flight loading system.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional reweighing devices mostly use single-point weighing sensors. During cargo transportation, the weight error is easily caused by the center of gravity shift, which exceeds the threshold. Especially for irregular cargo, the error rate is as high as 100%. Manual second static reweighing is required, and the daily processing capacity is low, far below the needs of air cargo terminals. In view of this, we propose a high-precision dynamic reweighing device for air cargo. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision dynamic weighing device for air cargo to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-precision dynamic weighing device for air cargo includes a mounting box, a display device fixedly mounted on the mounting box, and a weighing component disposed on the mounting box, the weighing component comprising: A weighing sensor is fixedly installed inside the mounting box. A signal processing device is fixedly installed on the mounting box. A mounting bracket is placed on the mounting box, and a rubber pad is fixedly installed at the bottom of the mounting bracket. A servo motor is fixedly mounted on the mounting frame, and a hinge box is fixedly mounted inside the mounting frame. A power roller is rotatably mounted on the hinge box. A conveying roller is fixedly installed on the power roller, and a rubber ring and a threaded rubber strip are fixedly installed on the conveying roller.

[0007] In a further embodiment, multiple sets of the rubber pad, power roller, conveyor roller, rubber ring, and threaded rubber strip are provided.

[0008] In a further embodiment, belts are installed between multiple sets of power rollers for transmission, and multiple sets of partitions are fixedly installed on the mounting frame, with the multiple sets of partitions arranged between multiple sets of conveyor rollers.

[0009] In a further embodiment, two sets of threaded rubber strips are provided on a single set of conveying rollers, with the two sets of threaded rubber strips rotating in opposite directions. The rubber pad is attached to the top of the weighing sensor, and the output end of the servo motor is connected to a single set of power rollers.

[0010] In a further embodiment, the mounting frame is provided with a support assembly, which includes a square box. The square box is fixedly installed inside the mounting frame, and one end of a spring rod is fixedly installed inside the square box. The other end of the spring rod is fixedly installed with a hinge frame, and a rubber roller is hingedly installed on the hinge frame.

[0011] In a further embodiment, the square box, spring rod, hinge frame, and rubber roller are provided in multiple sets.

[0012] In a further embodiment, the hinge frame slides inside the square box, and multiple sets of rubber rollers are attached to the bottom of the conveyor roller.

[0013] Compared with the prior art, this utility model provides a high-precision dynamic weighing device for air cargo, which has the following advantages: 1. This high-precision dynamic reweighing device for air cargo is designed to meet the efficient reweighing requirements of air cargo terminal departure scenarios. By setting up a reweighing component, this component works with a weighing sensor to collect cargo weight data in real time. The signal processing equipment processes the data and transmits it to the display device, replacing traditional manual reweighing and reducing the weight error rate. At the same time, a servo motor drives a power roller to drive multiple sets of conveyor rollers to rotate synchronously via a belt. The rubber rings on the conveyor rollers increase the friction with the cargo, and the threaded rubber strips with opposite rotation directions guide the cargo to the center from both sides, avoiding cargo deviation that could lead to inaccurate weighing and enabling parallel reweighing of multiple cargoes.

[0014] 2. This high-precision dynamic reweighing device for air cargo is equipped with a support component to meet the high-intensity continuous reweighing operation requirements of air cargo stations. This component, together with multiple sets of rubber rollers, fits against the bottom of the conveyor roller and provides support under the thrust of the spring rod. This prevents the conveyor roller from deforming due to uneven cargo weight and prevents wear of the conveyor roller caused by rigid support. The square box provides a stable installation space for the spring rod and the hinge frame, avoiding interference between components. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship.

[0019] Please see Figures 1-8 This utility model provides a technical solution: A high-precision dynamic weighing device for air cargo includes a mounting box 1, on which a display device 2 is fixedly mounted.

[0020] In one embodiment of this utility model, a weighing assembly 3 is provided on the mounting box 1. The weighing assembly 3 includes a weighing sensor 31, which is fixedly installed inside the mounting box 1. A signal processing device 32 is fixedly installed on the mounting box 1. A mounting frame 33 is placed on the mounting box 1. A rubber pad 34 is fixedly installed at the bottom of the mounting frame 33. A hinge box 36 is fixedly installed inside the mounting frame 33. A power roller 37 is rotatably mounted on the hinge box 36 and fixedly installed on the power roller 37. A rubber ring 39 is fixedly installed on the conveying roller 38. The mounting frame 33 is fixedly installed with threaded rubber strips 310, rubber pads 34, power rollers 37, conveyor rollers 38, rubber rings 39, and multiple sets of threaded rubber strips 310. Belts 311 are installed between the multiple sets of power rollers 37 for transmission. Multiple sets of partitions 312 are fixedly installed on the mounting frame 33 and are arranged between the multiple sets of conveyor rollers 38. Two sets of threaded rubber strips 310 are provided on each set of conveyor rollers 38, with the two sets of threaded rubber strips 310 rotating in opposite directions. Rubber pads 34 are attached to the top of the load cell 31. The output end of the servo motor 35 is connected to a single set of power rollers 37.

[0021] In this embodiment, during operation, the servo motor 35 on the mounting frame 33 is started, and its output drives a single set of power rollers 37 to rotate. The power rollers 37 drive multiple sets of power rollers 37 and conveyor rollers 38 to rotate synchronously through the belt 311, forming a continuous conveying channel. Air cargo is placed on the conveyor rollers 38 and moves into the weighing area with the conveyor rollers 38. At this time, the rubber pad 34 at the bottom of the mounting frame 33 transmits the weight of the cargo to the weighing sensor 31 inside the mounting box 1. The rubber pad 34 can buffer the impact of the cargo and avoid instantaneous pressure damage to the sensor. The weighing sensor 31 collects weight data and transmits it to the signal processing device 32 on the mounting box 1. After processing, the weight information is sent to the display device 2 to realize dynamic weighing. During the conveying process, the rubber ring 39 on the conveyor roller 38 increases the friction with the bottom of the cargo to prevent the cargo from slipping. The two sets of threaded rubber strips 310 on the single set of conveyor rollers 38 rotate synchronously with opposite directions, applying lateral thrust from both sides of the cargo to guide the cargo to the center of the conveying channel, avoiding the cargo from shifting and causing the center of gravity to deviate from the weighing sensor 31, thus ensuring accurate weight data.

[0022] In one embodiment of this utility model, a support component 4 is provided on the mounting frame 33. The support component 4 includes a square box 41, which is fixedly installed inside the mounting frame 33. One end of a spring rod 42 is fixedly installed inside the square box 41, and a hinge frame 43 is fixedly installed at the other end of the spring rod 42. A rubber roller 44 is hingedly installed on the hinge frame 43. Multiple sets of square box 41, spring rod 42, hinge frame 43 and rubber roller 44 are provided. The hinge frame 43 slides inside the square box 41, and multiple sets of rubber rollers 44 are attached to the bottom of the conveyor roller 38.

[0023] In this embodiment, when the conveyor roller 38 carries air cargo of different weights, the bottom of the conveyor roller 38 contacts multiple sets of rubber rollers 44. The spring rod 42 inside the square box 41 applies a continuous thrust to the hinge frame 43, so that the rubber rollers 44 fit tightly against the conveyor roller 38, providing upward support for the conveyor roller 38 and preventing the conveyor roller 38 from bending and deforming due to uneven cargo weight or overload. This ensures that the conveying channel is flat. The rubber rollers 44 rotate synchronously with the conveyor roller 38. By using rolling contact instead of rigid support, the wear of the conveyor roller 38 can be greatly reduced, and its service life can be extended.

[0024] In this application, all electrical components are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the display device 2, the weighing sensor 31, the signal processing device 32, and the servo motor 35.

The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. In addition, the standard parts are all conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art.
