Technical Field
[0001] This utility model relates to the field of electronic scale technology, and in particular to an electronic scale roller. Background Technology
[0002] In production lines, express sorting, warehousing and logistics scenarios, a large number of items need to be weighed continuously. Traditional static electronic scales require placing each item individually, waiting for weighing, and manual handling, which is inefficient and difficult to adapt to the needs of high-speed operations. Electronic scale rollers, due to their dynamic weighing characteristics, can complete weight detection during the conveying of items without requiring items to stop, greatly improving weighing efficiency. They have become key equipment in continuous operation scenarios. Their core requirements are not only to achieve the convenience of dynamic weighing, but also to ensure the stability of the equipment when handling items of different weights, especially to avoid damage to core components due to overloading, and to ensure long-term reliable operation.
[0003] In mainstream electronic scales, the rollers are connected to the scale sensor via a bracket. The sensor is fixed in the equipment base or mounting box. When the item moves with the roller, the weight is transmitted to the sensor through the weighing plate. The sensor converts the pressure signal into weight data to achieve dynamic weighing. Some devices will add a simple rigid support structure around the sensor to support the weight of the roller assembly when not weighing.
[0004] However, when the weight of an item exceeds the maximum pressure limit of the electronic scale sensor, the lack of effective physical support means that the sensor is easily damaged, leading to equipment downtime for repair and increased maintenance costs. Utility Model Content
[0005] In view of the above-mentioned problem that when the weight of the item exceeds the maximum pressure limit of the electronic scale sensor, the lack of effective physical support means makes the sensor easily damaged, leading to equipment downtime for maintenance and increased maintenance costs, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to enable dynamic weighing of items by moving the rollers without stopping, adapting to continuous operation scenarios and greatly improving weighing efficiency. The device is equipped with a limit adjustment block to limit the weighing connection block. When the weight is overloaded, the two abut against each other to form a rigid support, bearing the excess weight, effectively protecting the electronic scale sensor, reducing equipment maintenance costs and downtime. At the same time, the limit adjustment block can be driven to rise and fall by rotating the motor, flexibly adapting to electronic scale sensors of different specifications without replacing the entire equipment, reducing adaptation costs.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0028] Example 1
[0029] Reference Figure 1-4 This is the first embodiment of the present invention, which provides an electronic scale roller, including an electronic scale mounting box 1 and a fixed mounting base 2 inside the electronic scale mounting box 1. The fixed mounting base 2 is provided with a mounting connecting block 3 on one side, and an electronic scale sensor 4 is provided on one side of the mounting connecting block 3. It includes a weighing connecting block 5 installed on one side of the electronic scale sensor 4, a mounting bracket 6 on one side of the weighing connecting block 5, a mounting sleeve 7 on one side of the mounting bracket 6, a fixed connecting plate 8 on one side of the electronic scale mounting box 1, one end of the mounting sleeve 7 being inserted into the inside of the fixed connecting plate 8, and a fixed mounting rod 9 being provided inside the mounting sleeve 7.
[0030] A weighing plate 10 is provided on one side of the fixed mounting rod 9, and multiple weighing rollers 11 are provided on the inner side of the weighing plate 10. Multiple fixed bases 12 are provided on one side of the electronic scale mounting box 1. A limiting constraint groove 13 is opened on the inner side of the fixed mounting base 2. A lifting fixing block 17 is provided on the inner side of the limiting constraint groove 13. A lifting constraint groove 14 is opened on the inner side of the electronic scale mounting box 1. The lifting constraint groove 14 is connected to the inner side of the limiting constraint groove 13.
[0031] Example 2
[0032] Reference Figure 3-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it includes a lifting threaded sleeve 20 installed inside the electronic scale mounting box 1. A lifting fixing block 17 is provided on one side of the lifting threaded sleeve 20, and a limit adjustment block 18 is provided on one side of the lifting fixing block 17. The lifting threaded sleeve 20 is located inside the lifting constraint groove 14. A rotating connection groove 15 is opened on one side of the electronic scale mounting box 1. A rotating motor 21 is provided inside the rotating connection groove 15, and a rotating screw 22 is provided on one side of the rotating motor 21.
[0033] One end of the rotating screw 22 is inserted into the inner side of the lifting threaded sleeve 20. Two guide constraint grooves 16 are opened inside the electronic scale mounting box 1. Each guide constraint groove 16 is connected to the limit constraint groove 13. Two guide constraint rods 19 are provided on one side of the lifting fixing block 17. Each guide constraint rod 19 is inserted into the inner side of the corresponding guide constraint groove 16. The limit adjustment block 18 is located directly below the weighing connecting block 5.
[0034] In use, the electronic scale mounting box 1 is fixed to the ground by the fixed base 12 on one side to ensure the stability of the overall structure. The fixed mounting base 2 is installed inside the electronic scale mounting box 1. The mounting connecting block 3 on one side is fixedly connected to the electronic scale sensor 4. In the weighing assembly, the weighing connecting block 5 is fastened to the mounting bracket 6 by bolts. The mounting sleeve 7 on the other side of the mounting bracket 6 is connected to the fixed mounting rod 9 by bolts. The fixed mounting rod 9 is rigidly connected to the weighing plate 10. The weighing roller 11 inside the weighing plate 10 can rotate freely to provide rolling support for the transport of items.
[0035] When an item enters the weighing area, it moves on the weighing plate 10 as the weighing roller 11 rotates. The weight of the item is transmitted to the fixed mounting rod 9 through the weighing plate 10, and then to the weighing connecting block 5 through the mounting sleeve 7 and mounting bracket 6. Finally, it acts on the electronic scale sensor 4, which converts the pressure signal into weight data, completing the dynamic weighing of the item in real time. This eliminates the need for the item to stop, making it suitable for continuous operation scenarios such as production lines and express sorting. During this process, the weighing connecting block 5 and the electronic scale sensor 4 are in close contact to ensure accurate weight signal transmission without any errors caused by extra gaps.
[0036] Based on the maximum pressure limit of the electronic scale sensor 4, the height of the limit adjustment block 18 is pre-adjusted, and the rotation motor 21 inside the rotation connection groove 15 is started. Its output shaft drives the rotation screw 22 to rotate. One end of the rotation screw 22 is inserted into the inside of the lifting threaded sleeve 20, and the lifting threaded sleeve 20 is driven to move up and down along the lifting constraint groove 14 through thread engagement.
[0037] The lifting threaded sleeve 20 is fixedly connected to the lifting fixed block 17. The lifting fixed block 17 moves synchronously with it. At the same time, the guide constraint rod 19 on one side of the lifting fixed block 17 slides along the guide constraint groove 16 to avoid deviation during the lifting process and ensure that the limit adjustment block 18 is accurately lifted to the preset height. When the weight of the item does not exceed the limit, the weighing connecting block 5 and the limit adjustment block 18 maintain a small gap, which does not affect the weighing accuracy. When the item is overweight, the weighing connecting block 5 can move down to abut against the limit adjustment block 18.
[0038] When the weight of the item exceeds the maximum pressure limit of the electronic scale sensor 4, the weighing connecting block 5 moves downward slightly under the action of the excess weight, gradually approaching the limit adjustment block 18 until the two are completely in contact. At this time, the limit adjustment block 18 forms a rigid support with the electronic scale mounting box 1 through the lifting fixing block 17, the lifting threaded sleeve 20, and the lifting fixed block 17, bearing the weight exceeding the upper limit of the electronic scale sensor 4, preventing the weighing connecting block 5 from moving downward further, avoiding the electronic scale sensor 4 from being crushed due to overload, and realizing the protection of the core component.
[0039] When replacing the electronic scale sensor 4 with a different specification, the height of the limit adjustment block 18 needs to be readjusted, and the rotating motor 21 needs to be started again. Through the transmission of the rotating screw 22 and the lifting threaded sleeve 20, the lifting fixed block 17 and the limit adjustment block 18 are driven to rise and fall. The cooperation between the guide constraint rod 19 and the guide constraint groove 16 ensures that the limit adjustment block 18 always remains horizontal and is accurately located directly below the weighing connecting block 5, so as to avoid the failure of protection due to positional deviation.
[0040] After adjustment, turn off the rotating motor 21. The self-locking characteristics of the threads of the lifting threaded sleeve 20 and the rotating screw 22 can fix the height of the limit adjustment block 18 without the need for an additional locking structure.
[0041] The remaining structure is the same as that in Example 1.
[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
