Description

Technical Field

[0001] This utility model relates to the field of flour weighing technology, and more specifically, to an automatic flour weighing device for flour processing machinery. Background Technology

[0002] Flour is a powder made from wheat and is a staple food in most parts of northern China. There are many kinds of foods made from flour, with a wide variety of styles and flavors. Flour is rich in protein, fat, carbohydrates and dietary fiber. Traditional Chinese medicine believes that flour is sweet and cool in nature and has the effects of nourishing the heart and kidneys, strengthening the spleen and intestines, and relieving heat and thirst. After processing, flour needs to be weighed and bagged for easy storage.

[0003] Existing flour processing machinery and automatic flour weighing devices require multiple weighings if a certain amount of flour is needed. More importantly, when the conveyor mechanism delivers the flour to the weighing mechanism, the flour is loosely packed and occupies a large volume. After the flour is put into a quantitative packaging bag, there will be a situation where the packaging bag is full, but the required amount of flour has not yet been added. Therefore, it is inconvenient for users.

[0004] For example, the "Automatic Weighing Device for Flour Processing Machinery" disclosed in Chinese Patent (Application No.: CN202021603597.6) describes a device comprising a housing with two fixed seats fixedly connected to the inner wall of its bottom. A first groove is formed at the top of each fixed seat, and a second slider is slidably connected inside the first groove. A movable plate is fixedly connected to the top of the second slider. A second groove is formed on the side of the two movable plates that are close to each other, and the first slider is slidably connected inside the second groove. A second telescopic rod is fixedly connected to the inner wall of the second groove. This utility model device has a simple structure, is easy to operate, speeds up weighing, improves accuracy, and thus increases work efficiency while saving significant manpower, enhancing the device's practicality.

[0005] The automatic flour weighing device proposed in the aforementioned patent only achieves rapid weighing and improves weighing accuracy through the setting of multiple chutes, sliders and telescopic rods. However, it does not solve the problem of compressing the volume of flour to be weighed before packaging. Therefore, we have made improvements and proposed an automatic flour weighing device for flour processing machinery. Utility Model Content

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0040] Please refer to Figure 1 An automatic flour weighing device for flour processing machinery includes an installation component 10. The installation component 10 includes a base, and a working group 11 is provided on the top of the base. A processing channel 12 is provided through one side of the working group 11. A weighing trough 13 is provided on the bottom wall of the processing channel 12 on one side of the opening of the processing channel 12. An electronic scale 60 is provided at the bottom of the weighing trough 13. A transmission component 20 is provided on one side of the weighing trough 13 on the other side of the opening of the processing channel 12. A feeding component 50 is slidably connected above the electronic scale 60 inside the weighing trough 13. A pressing component 30 is installed on the top wall of the processing channel 12. A gathering component 40 is provided at the bottom of the pressing component 30. The transmission component 20 is used to transfer flour into the weighing trough 13. The weighed flour is compacted by the pressing component 30. The gathering component 40 is used to prevent the flour from overflowing from the weighing trough 13 during the compaction process. The weighed flour is bagged by the feeding component 50.

[0041] Please refer to Figure 2 An automatic flour weighing device for flour processing machinery is described. Its operation is as follows: First, the transmission component 20 continuously transfers the flour into the weighing tank 13. Once the reading on the electronic scale 60 indicates the required flour weight, the weighed flour is compacted by the pressing component 30. The gathering component 40 prevents the flour from overflowing from the weighing tank 13 during compaction. Then, the discharging component 50 is pulled out of the weighing tank 13, thereby bagging the weighed flour. This prevents the bag from being full due to large gaps between flour particles, even if the flour in the bag has not reached the required weight.

[0042] Furthermore, such as Figure 4 As shown, the transmission assembly 20 includes a conveyor frame 21. A feeding plate 22 is rotatably connected to the side of the conveyor frame 21 near the weighing tank 13. A support rod 23 is fixedly connected between the end of the feeding plate 22 away from the conveyor frame 21 and the conveyor frame 21. The support rod 23 is made of rubber. The bottom end of the feeding plate 22 is located inside the weighing tank 13, thereby preventing flour from overflowing from the weighing tank 13 during the process of the flour being transferred from the conveyor frame 21 to the weighing tank 13. During the process of the pressing assembly 30 compacting the flour, the rubber support rod 23 allows the feeding plate 22 to move closer to the conveyor frame 21. After the pressing is completed, the restoring force of the support rod 23 allows the feeding plate 22 to return to its original position where its lower end is located inside the weighing tank 13.

[0043] Furthermore, such as Figure 5As shown, the pressing assembly 30 includes a fixed frame 31 fixedly connected to the top wall of the processing channel 12. A hydraulic rod 32 is fixedly connected to the center of the fixed frame 31. A pressing plate 33 is provided at the end of the hydraulic rod 32 away from the fixed frame 31. The pressing plate 33 and the piston end of the hydraulic rod 32 are fixedly connected. Several stabilizing rods 34 are slidably connected to the edge of the pressing plate 33. One end of each of the stabilizing rods 34 is fixedly connected to the fixed frame 31. After the flour is weighed, the piston end of the hydraulic rod 32 drives the pressing plate 33 to compact the flour on the top of the feeding assembly 50 with the cooperation of the stabilizing rods 34.

[0044] Furthermore, such as Figure 6 As shown, the gathering assembly 40 includes a gathering groove 41 extending upwards from the bottom of the pressure plate 33, a sliding groove extending upwards from the bottom of the pressure plate 33 and located around the gathering groove 41, and a plurality of limiting grooves 44 extending upwards from the bottom of the sliding groove. Each of the limiting grooves 44 has a limiting rod 43 slidably connected within it. Each limiting rod 43 has a limiting arm 42 fixedly connected at its end away from the limiting groove 44. The limiting arm 42 is slidably connected to the sliding groove. A plurality of springs 45 are fixedly connected between the limiting arm 42 and the top wall of the sliding groove, and each spring 45 is sleeved on the limiting arm 44. Outside of rod 43; during the process of the pressing assembly 30 compacting the flour, the limiting arm 42 first contacts the feeding assembly 50, thereby confining the flour within the limiting arm 42 and the gathering groove 41 to prevent it from overflowing. As the pressing plate 33 moves closer to the flour, the limiting rod 43 slides into the limiting groove 44, causing the limiting arm 42 to retract into the chute. During this period, the spring 45 is compressed. After the flour is compacted, the hydraulic rod 32 removes the thrust on the pressing plate 33, and the limiting arm 42 is extended from the chute under the restoring force of the spring 45, waiting for the next operation.

[0045] Furthermore, such as Figure 7 As shown, the feeding assembly 50 includes a holding plate 51. A pair of distancing edges on the top of the holding plate 51 are each provided with actuating grooves 52. Actuating frames 53 are slidably connected within each of the two actuating grooves 52. A mounting frame is fixedly connected between the two actuating frames 53, and a cleaning brush 54 is snapped onto the top of the mounting frame. The outer wall of the pressing plate 33 is attached to the inner wall of the weighing tank 13. The holding plate 51 is made of polytetrafluoroethylene (PTFE). PTFE has a very smooth surface and hardly adheres to any substance, providing good sliding performance and preventing flour from adhering to the holding plate 51. After the flour on the top of the holding plate 51 is weighed, the holding plate 51 is pulled out of the weighing tank 13. The actuating frames 53 are continuously pushed back and forth, driving the cleaning brush 54 to scrape the flour on the top of the holding plate 51 into the packaging bag. After bagging, the holding plate 51 is reinserted into the weighing tank 13, and the actuating frames 53 return to their original position under the action of the outer wall of the weighing tank 13.

[0046] The automatic flour weighing device for flour processing machinery provided by this utility model is used as follows:

[0047] First, the transmission component 20 continuously transfers flour into the weighing tank 13. Specifically, the bottom end of the feeding plate 22 is located inside the weighing tank 13 to prevent flour from overflowing during the process of being transferred from the conveyor frame 21 to the weighing tank 13. During the process of the pressing component 30 compacting the flour, the rubber support rod 23 allows the feeding plate 22 to move closer to the conveyor frame 21, and after the pressing is completed, the restoring force of the support rod 23 allows the feeding plate 22 to return to its original position inside the weighing tank 13. After the reading on the electronic scale 60 shows that the required weight of flour has been reached, the pressing component 30 compacts the weighed flour. Specifically, after the flour is weighed, the piston end of the hydraulic rod 32 drives the pressing plate 33, with the cooperation of the stabilizing rod 34, to compact the flour at the top of the feeding component 50. The gathering component 40 is used to prevent flour from overflowing from the weighing tank 13 during the compaction process. Specifically, during the process of the pressing component 30 compacting the flour, the limiting arm 42 first engages with the feeding component. The pressure plate 33 moves closer to the flour, and the limiting rod 43 slides into the limiting groove 44, causing the limiting arm 42 to retract into the chute. During this process, the spring 45 is compressed. After the flour is compacted, the hydraulic rod 32 releases its thrust on the pressure plate 33, and the limiting arm 42 extends out of the chute under the restoring force of the spring 45, ready for the next operation. Then, the feeding assembly 50 is pulled out of the weighing tank 13, thereby... The weighed flour is bagged to prevent the bag from being full but not yet reaching the required weight due to large gaps between the flour particles. Specifically, after the flour on the top of the holding plate 51 is weighed, the holding plate 51 is pulled out of the weighing trough 13, and the agitator 53 is pushed back and forth to drive the cleaning brush 54 to scrape the flour on the top of the holding plate 51 into the bag. After bagging, the holding plate 51 is reinserted into the weighing trough 13, and the agitator 53 returns to its original position under the action of the outer wall of the weighing trough 13.
