A first drive motor is located on the opposite side of one side of the frame, and a rotating rod is fixedly connected to the output shaft of the first drive motor. By coordinating the frame, weighing seat, rotating seat, through slot, first drive motor, and rotating rod, the weighing device can be placed inside a sorting platform during use, allowing packages on the sorting platform to be conveyed to the conveying component and weighed by the weighing seat. After weighing, the rotating motor drives the weighing seat and the conveying component to rotate, thereby conveying packages of a specific weight to a specific sorting platform. This avoids the need for manual weighing of packages, improving work efficiency and reducing the labor intensity of personnel.

[0004] When a conveyor belt comes into contact with goods, dust and impurities may adhere to its surface. If these dust and impurities are not cleaned in time, they may affect the accuracy of weighing and cause errors in the weighing data. Over time, this accumulation may also affect the service life of the conveyor belt. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a dust removal component, the scraper can clean the impurities attached to the surface of the conveyor belt, and the dust discharge plate can discharge the dust and impurities, preventing a large amount of dust and impurities from adhering to the surface of the conveyor belt and affecting the weighing effect. When encountering dust and impurities with strong adhesion, the torsion spring will apply a reverse force to the dust discharge plate through the rotating shaft, so that the scraper always fits tightly against the surface of the conveyor belt. At the same time, the tension sensor monitors the contact pressure between the scraper and the conveyor belt in real time through the connecting rod. When the pressure value exceeds the preset threshold, it can promptly remind the operator to inspect and maintain the scraper or the conveyor belt. 2. By setting up scanning components, the connecting frame provides stable support for the universal seat, and the omnidirectional ball can drive the fixed rod to rotate flexibly, allowing the measuring device to adjust its angle according to the position and shape of different goods. This ensures accurate scanning and measurement of goods moving on the conveyor belt, identifies the packaging area of ​​the goods, and calculates the weight per unit area of ​​the goods by combining dynamic weighing data, providing multi-dimensional data support for cargo classification and loading planning in logistics transportation.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a dynamic weighing device for a logistics conveyor line, including a support frame 1, an electronic scale platform 2 fixedly installed on the top of the support frame 1, a drive frame 3 fixedly installed on the top of the electronic scale platform 2, a conveyor belt 4 connected to the top of the drive frame 3, dust removal components symmetrically arranged on both sides of the support frame 1, a display screen 6 fixedly installed on the top of the support frame 1, a scanning component arranged on one side of the support frame 1, and auxiliary slots 8 symmetrically opened on both sides of the drive frame 3. The dust removal assembly includes mounting blocks 51, with two mounting blocks 51 symmetrically fixed on both sides of the support frame 1. A dust removal plate 52 is rotatably connected between each two mounting blocks 51. A scraper 53 is fixedly mounted on the top of the dust removal plate 52. The scraper 53 is made of high-elasticity rubber, and its top contacts the bottom of the conveyor belt 4. When the conveyor belt 4 is running, the scraper 53 can scrape off dust, fine debris, etc., adhering to the surface of the conveyor belt 4, preventing impurities from accumulating and affecting subsequent weighing accuracy. The dust removal assembly also includes rotating shafts 54, each rotatably connected inside the mounting block 51. A torsion spring 55 is fitted around the outer end of each rotating shaft 54. A connecting rod 56 is fixedly installed at one end of the rotating shaft 54, and a tension sensor 57 is fixedly installed at the other end of the connecting rod 56. The ash discharge plate 52 passes through the interior of the auxiliary trough 8. The top of the scraper 53 is slidably connected to the bottom of the conveyor belt 4. The two ends of the torsion spring 55 are fixedly connected to the inner wall of the mounting block 51 and the ash discharge plate 52, respectively. The connecting rod 56 passes through one of the mounting blocks 51. The operator can intuitively understand the working status of the scraper 53 through the display screen 6. When the tension value exceeds the preset range, the system will automatically issue an early warning prompt so that the scraper 53 can be checked or replaced in time to ensure the continuous and stable operation of the ash removal component and further ensure the measurement accuracy and reliability of the weighing device.

[0018] Please see Figure 1 and Figure 2 The scanning assembly includes a connecting frame 71, which is fixedly mounted on one side of the support frame 1. A universal base 72 is fixedly mounted on the bottom of the connecting frame 71. A universal ball 73 is rotatably connected inside the universal base 72. A fixing rod 74 is fixedly mounted on the bottom of the universal ball 73. A measuring device 75 is fixedly mounted on the bottom end of the fixing rod 74. A tension sensor 57 is located on one side of one of the mounting blocks 51. The measuring device 75 is located on the top of the conveyor belt 4. The fixing rod 74 and the universal ball 73 are detachably connected. In this embodiment, the design of the universal base 72 and the universal ball 73... This allows the measuring device 75 to flexibly adjust its detection angle. Workers can change the scanning direction of the measuring device 75 by rotating the universal ball 73 according to the different sizes and shapes of the goods, ensuring that the goods can be accurately scanned during transportation. The measuring device 75 has a built-in high-definition camera and laser scanning module, which can quickly identify the shape and surface information of the goods and transmit the data to the control system in real time. It is then linked with the weight data obtained by the electronic scale platform 2 for analysis, providing more comprehensive goods information for the logistics management system and helping to achieve refined management and tracking of goods.

[0019] Working principle: When goods are conveyed to the electronic weighing platform 2 via conveyor belt 4, the weighing sensor inside the electronic weighing platform 2 collects the weight data of the goods in real time and transmits the data to the control system. After processing the weight data, the control system displays the weighing result on the display screen 6. At the same time, the measuring device 75 in the scanning component scans the goods to obtain information such as the shape and size of the goods. This information, along with the weight data, is transmitted to the control system to realize the integration and recording of goods information. During the operation of conveyor belt 4, the scraper 53 of the dust removal component is always in contact with the bottom of conveyor belt 4. As the conveyor belt 4 rotates, the scraper 53 scrapes off the dust and debris on its surface, and the scraped impurities fall onto the ash discharge plate 5. 2. As the ash discharge plate 52 maintains a stable angle under the action of the torsion spring 55, impurities can slide down the ash discharge plate 52 to the outside of the device. When the scraper 53 is worn or jammed by foreign objects due to long-term use, the friction between it and the conveyor belt 4 changes, causing the deformation degree of the torsion spring 55 to change. The connecting rod 56 drives the rotating shaft 54 ​​to rotate. The tension sensor 57 detects the change in tension value and transmits the signal to the control system. If the tension value exceeds the preset range, the display screen 6 will display a warning message to remind the staff to check or replace the scraper 53. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
