Description

Technical Field

[0001] The utility model belongs to the technical field of belt scales, and in particular relates to a multi-support-roller array type high-precision belt scale. Background Art

[0002] The multi-roller array belt scale adopts a multi-roller array structural design, which consists of multiple single-point suspended weighing units. Each unit consists of a weighing sensor and two sets of rollers. This design can effectively improve the accuracy and stability of weighing.

[0003] Most high-precision belt scales with multiple support rod arrays have some drawbacks. For example, when weighing powdered items, powders falling vertically onto the device can cause them to scatter, affecting the weighing results and leading to inaccurate data. Furthermore, powders can accumulate on the device, causing uneven weighing and affecting the results. To address these issues, we propose a high-precision belt scale with multiple support rod arrays. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-support rod array type high-precision belt scale to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a multi-support rod array type high-precision belt scale, comprising:

[0006] A multi-support roller array belt scale body, on which a feed shell is fixedly installed, two rotating plates are symmetrically installed in the feed shell, and a power chamber is opened in the feed shell, two worms are rotatably installed in the power chamber, and two worm gears are meshed and installed on one side of each of the two worms. The four worm gears are respectively located on one side of the four rotating plates, and one end of the four worm gears passes through the power chamber and is fixedly connected to the four rotating plates respectively. The four worm gears are all rotatably connected to the power chamber;

[0007] A drive assembly is located in the feed housing and is used to drive the two worms to rotate in opposite directions;

[0008] Two sliding grooves 1, both of which are opened in the multi-support rod array belt scale body and located on one side of the feed shell, and a guide plate is slidably installed between the two sliding grooves 1;

[0009] A power assembly, the power assembly being located in the multi-support roller array type belt scale body and being used to drive the guide plate to slide;

[0010] Sliding groove 2 is opened in the body of the multi-support rod array belt scale and is located at the exit of the body of the multi-support rod array belt scale. A scraper is slidably installed in the sliding groove 2, and a plurality of springs fixed to the inner wall of the sliding groove 2 are fixed on the bottom of the scraper.

[0011] In this technical solution, when powdery items need to be weighed, the powdery items are first poured into the feed shell, and then the powdery items fall to the top of the uppermost rotating plate. Under the action of gravity and the inclined rotating plate, the powdery items will move downward to the remaining rotating plates. Under the action of the four rotating plates, it can be ensured that the powdery items will not fall vertically onto the belt of the multi-support stick array belt scale body. The powdery items will move slowly downward, avoiding the situation where the powdery items float around and affect the weighing results, thereby ensuring high weighing data accuracy.

[0012] When the feeding speed of the powdered article needs to be adjusted, the driving assembly provided can drive the two worms to rotate in opposite directions. The two worms respectively drive the worm wheels meshing with them to rotate downward, and the four worm wheels respectively drive the four rotating plates to rotate downward. The greater the downward rotation angle of the rotating plates, the faster the feeding speed of the powdered article, which makes it convenient for the staff to control the feeding speed of the powdered article.

[0013] The power assembly is set up to drive the guide plate to slide downward, and the guide plate can intercept the powdered objects accumulated on the belt of the multi-support rod array belt scale body, ensuring that the powdered objects on the belt of the multi-support rod array belt scale body will not accumulate too high, ensuring that the powdered objects are weighed evenly. At the same time, the interception height can be adjusted according to the type of objects. It has a wide range of applications, and uniform weighing reduces rework and waste caused by inaccurate weighing, further improving production efficiency.

[0014] At the same time, under the action of several spring rebound forces, the scraper will slide upward and contact with the belt on the multi-support rod array belt scale body, ensuring that the powdery items on the belt of the multi-support rod array belt scale body can be scraped off, ensuring that no powdery items are attached to the belt of the multi-support rod array belt scale body, and ensuring that the weighing data is the same as the data of the powdery items discharged from the multi-support rod array belt scale body, reducing rework and waste caused by the difference between weighing and actual data, and further improving production efficiency.

[0017] In this technical solution, when it is necessary to adjust the feeding speed of powdered materials, first rotate one of the bevel gears 1 and drive the other bevel gear 1 to rotate, the two bevel gears 1 respectively drive the two bevel gears 2 engaged with them to rotate in the opposite direction, the two bevel gears 2 respectively drive the two worms to rotate in the opposite direction, the two worms respectively drive the worm wheels engaged with them to rotate downward, the four worm wheels respectively drive the four rotating plates to rotate downward, the greater the downward rotation angle of the rotating plates, the faster the feeding speed of the powdered materials, which is convenient for the staff to control the feeding speed of the powdered materials.

[0018] In the above technical solution, further, the power assembly includes:

[0019] A threaded rod is rotatably mounted in one of the sliding grooves and is located below the guide plate. The upper end of the threaded rod passes through the guide plate and one of the sliding grooves and extends to the outside. The threaded rod is threadedly connected to the guide plate.

[0020] In this technical solution, the staff rotates the threaded rod, and under the action of the thread, the guide plate will slide downward, and at the same time the guide plate slides on the guide column to ensure the stability of the sliding on both sides of the guide plate. The guide plate can intercept the powdered items accumulated on the belt of the multi-support rod array belt scale body, ensuring that the powdered items on the belt of the multi-support rod array belt scale body will not accumulate too high, ensuring that the powdered items are weighed evenly, and at the same time the interception height can be adjusted according to the type of item. It has a wide range of applications, and uniform weighing reduces rework and waste caused by inaccurate weighing, further improving production efficiency.

[0082] Working principle: When powdery items need to be weighed, first pour the powdery items into the feed shell 2, and then the powdery items fall to the top of the uppermost rotating plate 4.

The two bevel gears 12 respectively drive the two bevel gears 2 13 meshing therewith to rotate in the opposite direction. The two bevel gears 2 13 respectively drive the two worm gears 5 to rotate in the opposite direction. The two worm gears 5 respectively drive the worm gears 6 meshing therewith to rotate downward.

Under the action of the thread, the guide plate 8 slides downward, and at the same time, the guide plate 8 slides on the guide column 17 to ensure the stability of the sliding of the guide plate 8 on both sides. The guide plate 8 can intercept the powdery items accumulated on the belt of the multi-support stick array belt scale body 1, ensuring that the powdery items on the belt of the multi-support stick array belt scale body 1 will not accumulate too high, ensuring that the powdery items are evenly weighed, and at the same time, the interception height can be adjusted according to the type of items. The application range is wide, and the uniform weighing reduces rework and waste caused by inaccurate weighing, further improving production efficiency.
