Description

Technical Field

[0001] This utility model belongs to the field of weighing equipment technology, specifically a weighing device with multiple weighing ranges. Background Technology

[0002] In daily production and processing, it is often necessary to weigh the finished parts. Weighing typically involves transporting the object to be weighed onto a weighing device. Existing weighing devices, such as the weighing display board disclosed in Chinese patent document CN217845368U, include a detection module consisting of a weighing transport device, a sensing module, a counting module, and a control module, as well as a display module consisting of an electronic display board. In actual use, workers can more conveniently know the quantity and quality of the items being weighed during production. However, this device can only weigh items within a certain weighing range. When the mass of the item being weighed is less than the predetermined range of the weighing sensor, inaccurate weighing may occur, requiring replacement of the weighing sensor or the weighing device, which is quite troublesome. Utility Model Content

[0003] To address the above problems, this utility model provides a weighing device with multiple weighing ranges. By integrating two weighing devices with different weighing ranges within a single weighing device, the weight of small objects can be accurately identified when using this device, eliminating the need to change weighing devices during the weighing process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A multi-range weighing device, the weighing mechanism including a primary weighing machine and a secondary weighing mechanism; the primary weighing machine includes a first frame; a first conveying roller is provided on the first frame, and a first weighing sensor is provided under the first frame; the secondary weighing mechanism includes a second frame, a second conveying roller is provided on the second frame, and the second frame is mounted on a lifting mechanism; the lifting mechanism is used to push the second frame upward; a second weighing sensor is provided on the second frame.

[0006] As a further improvement to the above technical solution, the range of the first weighing sensor is greater than the range of the second weighing sensor.

[0007] As a further improvement to the above technical solution, the first conveying rollers are spaced apart on the first frame, and the second conveying roller is located directly below the gap formed by two adjacent first conveying rollers. The width of the gap formed by the two adjacent first conveying rollers is greater than the diameter of the second conveying roller.

[0008] As a further improvement to the above technical solution, the second conveying roller is mounted on the second frame on both sides by mounting plates, and the length of the mounting plates is greater than the diameter of the first conveying roller.

[0009] As a further improvement to the above technical solution, the second frame is mounted on the support plate, and a second weighing sensor is provided between the second frame and the support plate; the support plate is mounted on the lifting mechanism.

[0010] As a further improvement to the above technical solution, the length of the second conveying roller is less than the length of the first conveying roller.

[0011] As a further improvement to the above technical solution, the support leg of the first frame is located on the first weighing sensor; the first frame and the second frame are set independently of each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: It provides a weighing device with multiple weighing ranges. By integrating two weighing devices with different weighing ranges in one weighing device, when using this device to weigh small objects, the weight of the object can be accurately identified without changing the weighing device during the weighing process.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the protection scope of this utility model in any way. Example

[0018] like Figure 1-3As shown, a weighing device with multiple weighing ranges includes a first frame 1 and a second frame 2. The first frame 1 is provided with a first conveying roller 11. The second frame 2 is provided with a second conveying roller 21 and is mounted on a lifting mechanism 5. The lifting mechanism 5 is used to push the second frame 2 upward so that the second conveying roller 21 on the second frame 2 replaces the first conveying roller 11 on the first frame 1 to perform the weighing function. A first weighing sensor 6 is provided under the first frame 1 and a second weighing sensor 3 is provided on the second frame 2.

[0019] Specifically, the range of the first weighing sensor 6 is greater than the range of the second weighing sensor 3.

[0020] Specifically, the first conveying rollers 11 are spaced apart on the first frame 1, and the second conveying roller 21 is located directly below the gap formed by two adjacent first conveying rollers 11. The width of the gap formed by two adjacent first conveying rollers 11 is greater than the diameter of the second conveying roller 21.

[0021] Specifically, the second conveying roller 21 is mounted on the second frame 2 on both sides via mounting plates 22, and the length of the mounting plates 22 is greater than the diameter of the first conveying roller 11.

[0022] Specifically, the second frame 2 is mounted on the support plate 4, and a second weighing sensor 3 is disposed between the second frame 2 and the support plate 4; the support plate 4 is mounted on the lifting mechanism 5; the lifting mechanism 5 can be one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, wherein at least two lifting mechanisms 5 are provided, and in this embodiment, four are provided, located at the four corners of the support plate 4 respectively.

[0023] Specifically, such as Figure 2 As shown, the length of the second conveying roller 21 is less than the length of the first conveying roller 11, which facilitates the second conveying roller 21 extending out from the gap between the first conveying rollers 11.

[0024] Specifically, such as Figure 1 As shown, each of the four support legs of the first frame 1 is equipped with a first weighing sensor 6; the first frame 1 and the second frame 2 are set independently of each other.

[0025] When weighing items, the items first go onto the first conveyor roller 11 and are weighed by the first weighing sensor 6 set under the first frame 1. When the weight of the item is less than the preset weighing range of the first weighing sensor 6, the lifting mechanism 5 lifts the second conveyor roller 21 and the second frame 2, so that the item is separated from the first conveyor roller 11 and the weight of the item falls onto the second weighing sensor 3. The weight of the item is accurately weighed by the second weighing sensor 3.

[0027] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only used to help understand the method and core ideas of this utility model.

[0028] The above description is only a preferred embodiment of this utility model. It should be noted that due to the limitations of written expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principle of this utility model, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
