Description

Technical Field

[0001] The utility model belongs to the technical field of rotor scales, and in particular relates to a rotor scale and a weighing system. Background Art

[0002] A rotor scale is a weighing device commonly used for quantitative feeding of powders. In actual use, the rotor scale feeds materials in a consistent manner to ensure that the amount of material fed each time is consistent. For existing rotor scales, if materials are transported through equipment such as conveyor belts, the feeding amount can be controlled by controlling the speed of the conveyor belt. However, for rotor scales with silos, materials are placed in the silo at one time, and subsequent materials enter the rotor scale by gravity. At this time, it is difficult to ensure the consistency of material feeding. Utility Model Content

[0017] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0018] Example:

[0019] like Figure 1 As shown, a rotor scale includes a rotor scale body 100, a storage bin 200, a feed valve 300 and a bracket 400;

[0020] The rotor scale body 100 is provided with a feed inlet and a discharge port, wherein the feed inlet is located on the top surface of the rotor scale body 100 and the discharge port is located on the bottom surface of the rotor scale body 100;

[0021] The storage bin 200 is connected to the feed port, the feed valve 300 is arranged at the discharge end of the storage bin 200, and the feed valve 300 is provided with a pressure detection module 500; a control module 600 is provided on the rotor scale body 100, the control module 600 is electrically connected to the feed valve 300 and the pressure detection module 500, and the control module 600 is used to control the opening of the feed valve 300; the bracket 400 is connected to the rotor scale body 100.

[0022] The rotor scale controls the opening of the storage bin 200 through the feed valve 300, thereby controlling the speed at which the material in the storage bin 200 falls into the rotor scale body 100, and achieving the purpose of controlling the material feeding amount. At the same time, a pressure detection module 500 is provided on the feed valve 300, so as to detect the pressure of the material on the feed valve 300 in real time, and the control module 600 compares the actual pressure value with the preset pressure value. The control module 600 adjusts the opening of the feed valve 300 in real time according to the difference, so as to ensure the consistency of the pressure of the material entering the rotor scale body 100 on the feed valve 300, reduce the influence of the pressure change in the storage bin 200 on the material feeding amount, and help to improve the control accuracy.

[0023] During operation, the feed valve 300 is closed, and an appropriate amount of material is poured into the storage bin 200. The pressure detection module 500 starts and measures the pressure of the material on the feed valve 300. The control module 600 is provided with a preset pressure value. The difference is obtained by comparison. The control module 600 controls the feed valve 300 to open, so that the material flows from the storage bin 200 to the rotor scale body 100, and the material flows out through the discharge port of the rotor scale. At the same time, during the discharge process of the storage bin 200, the pressure detection module 500 and the control module 600 keep working throughout the whole process to measure and compare the pressure in real time, so as to adjust the opening of the feed valve 300 in real time to ensure that the material feeding amount remains consistent. After the feeding is completed or all the materials are transported, the control module 600 controls the feed valve 300 to close.

[0024] It is easy to understand that the bracket 400 is used to install the rotor scale body 100 and to raise the discharge port of the rotor scale body 100 to facilitate the outflow of materials. In addition, the bracket 400 can be constructed as any suitable structure; similarly, the pressure detection module 500 can select any suitable commercially available pressure detection sensor.

[0025] In a possible implementation, the storage bin 200 is constructed as a conical bin with a large top and a small bottom. Based on the above design, the storage bin 200 uses gravity to realize the flow of materials, which reduces the related power equipment, reduces costs and can reduce the failure rate. Figure 1 As shown, the conical bin is vertical, and the lower end of the conical bin is the discharge end of the storage bin 200. There is no need to worry about the phenomenon of material residue, which helps to improve the thoroughness of material delivery.

[0026] In a possible implementation, the control module 600 uses an electric actuator. Based on the above design, the electric actuator has a variety of types and models, with a wide range of options, and can be selected according to different use environments, with good adaptability, which improves the practicality of the rotor scale.

[0027] In a possible implementation, the upper portion of the bracket 400 is connected to the rotor scale body 100, and the lower portion of the bracket 400 extends to below the discharge port of the rotor scale body 100. Based on the above design, the bracket 400 effectively raises the height of the discharge port of the rotor scale body 100 to facilitate the placement of storage equipment or other equipment, which helps to improve the convenience of subsequent processing and use of materials.

[0028] In a possible implementation, a storage device is provided below the discharge port of the rotor scale body 100, and the upper part of the storage device extends to the lower part of the bracket 400. Based on the above design, the storage device can be any suitable commercially available device to meet the use requirements under different production conditions.

[0029] This embodiment introduces a weighing system based on the rotor scale, and the weighing system includes the rotor scale. Based on the above design scheme, the weighing system can add any suitable number and type of functional modules, and further enrich the functions on the basis of achieving weighing to meet different production needs. And it is easy to understand that the functional modules can be selected from any suitable commercially available equipment, with a wide range of choices and good practicality.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
