[0022] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0023] An embodiment of the present utility model discloses a dynamic weighing system.

[0024] According to the appendix Figures 1-5As shown in the figure, it includes a support frame 1. On the top of the support frame 1, there is a side weighing plate 2. On the outer walls on both sides of the support frame 1, there are material boxes 203. On one side of the weighing plate 2, there is an identification display screen 201. On both sides of the top of the support frame 1, there are fixedly connected fixed side plates 101. On both sides of the weighing plate 2, they are fixedly connected to the outer wall of the support frame 1 through connection components. A conveyor belt 202 is sleeved on the outer peripheral wall of the weighing plate 2. The inner peripheral wall of the conveyor belt 202 is in mutual fit with the outer peripheral wall of the weighing plate 2. On the outer walls on both sides of the support frame 1, there are drive components. Both sides of the conveyor belt 202 are connected to the drive components. When the drive components work, they drive the conveyor belt 202 to rotate to convey materials; when weighing an item, first place the item to be weighed on one side of the top of the conveyor belt 202. Drive the driving roller 205 to work through a driver, so that the conveyor belt 202 conveys the item on the top. During the conveying process, the weighing plate 2 can weigh the weight of the item and transmit the detected data to the identification display screen 201. The weighing data is analyzed by the identification display screen 201 to obtain a result. Finally, according to the obtained weight result of the item, the discharge drive plates 204 at the material boxes 203 are respectively started, so that the discharge drive plates 204 rotate to the top of the conveyor belt 202 to block the item in the weighing and conveying process. Then, start the driver at the discharge drive plate 204 again, so that the discharge drive plate 204 drives the blocked item into the interior of the material box 203 for collection, and thus different weights of items can be collected.

[0025] A cavity is formed between the conveyor belt 202 and the support frame 1. At the bottom of the conveyor belt 202, there is a cleaning scraper 3. The cleaning scraper 3 is fixedly connected to the fixed side plate 101 through a mounting component. The top of the cleaning scraper 3 is in fit with the bottom of the conveyor belt 202. There is a waste box 4 at the cleaning scraper 3. The waste box 4 collects the cleaning waste. The cleaning scraper 3 and the waste box 4 are located inside the cavity. During the weighing process, by installing the cleaning scraper 3 at the bottom of the conveyor belt 202, the waste adhered to the top of the conveyor belt 202 can be scraped and cleaned by the cleaning scraper 3, and thus it can be avoided that during the weighing and conveying process, the waste adheres to the top of the conveyor belt 202 and affects the weight of the weighed item. Furthermore, the waste on the top of the conveyor belt 202 can be cleaned in advance to avoid the waste affecting the weighing accuracy of the weighing plate 2 for the item.

[0026] The driving component drives the conveyor belt 202 to rotate, enabling the cleaning scraper 3 to comprehensively scrape and clean the waste on the outer peripheral wall of the conveyor belt 202. The cleaning scraper 3 is located between the two fixed side plates 101. The installation component includes a connecting piece 301 and a fixing bolt 302. The connecting piece 301 is fixedly installed on the outer walls on both sides of the cleaning scraper 3, and the fixing bolt 302 is threadedly connected inside the connecting piece 301 and the fixed side plate 101. When the driving component works and the driving roller 205 drives the conveyor belt 202 to rotate for item conveying, the position of the cleaning scraper 3 remains unchanged. Thus, the purpose of always enabling the cleaning scraper 3 to comprehensively clean the waste adhered to the top of the conveyor belt 202 can be achieved, avoiding the waste from affecting the weighing accuracy of the weighing plate 2 for the item.

[0027] The driving component includes a driving roller 205, a driving gear 206, and a driving toothed belt 207. The driving roller 205 is rotatably connected to the inner parts at both ends of the conveyor belt 202. Both ends of the driving roller 205 pass through the inner wall of the fixed side plate 101 and are fixedly connected to the driving gear 206. The side walls on both sides of the conveyor belt 202 pass through the inner wall of the fixed side plate 101 and are fixedly connected to the driving toothed belt 207. The driving toothed belt 207 is sleeved on the outer peripheral wall of the driving gear 206 and meshes with the driving gear 206. By starting the driver, the driver drives the driving component to work. Thus, the driving gears 206 at both ends can mesh with the driving toothed belt 207, enabling the driving toothed belt 207 to drive the conveyor belt 202 to rotate for item conveying. At the same time, it can ensure that the inner peripheral wall of the conveyor belt 202 fits with the outer peripheral wall of the weighing plate 2, enabling the weighing plate 2 to weigh the item on the top of the conveyor belt 202, and the weighing plate 2 supports the item.

[0028] The connecting component includes a fixing rod 208. One end of the fixing rod 208 is fixedly connected to the outer wall of the fixed side plate 101, and the other end passes through the outer wall of the fixed side plate 101 and is fixedly connected to the weighing plate 2. A limiting groove 401 is opened at the top of the support frame 1, and a first magnet 402 is arranged at the inner bottom of the limiting groove 401. A second magnet 403 is fixedly connected to the bottom of the waste box 4. The first magnet 402 and the second magnet 403 are magnetically attracted to each other. When installing the waste box 4 and the support frame 1, first pick up the waste box 4, align the bottom of the waste box 4 with the limiting groove 401, and insert the waste box 4 into the limiting groove 401. Through the magnetic attraction of the two groups of magnets, the purpose of installing and locking the waste box 4 can be achieved. During the process of scraping and cleaning the waste by the cleaning scraper 3, the waste box 4 at the cleaning scraper 3 can collect the scraped waste, enabling the scraped waste to fall into the waste box 4 for collection.

[0029] The material box 203 is located on one side of the weighing plate 2. A plurality of discharging driving plates 204 are arranged at the top of the support frame 1. The discharging driving plates 204 correspond to the positions of the material boxes 203 respectively. The plurality of material boxes 203 correspond to four groups of articles with different weights. The weight of the article is weighed and detected by the weighing plate 2. Subsequently, the discharging driving plate 204 at the material box 203 corresponding to the weight of the weighed article is activated, and the article is blocked and driven into the interior of the material box 203 for collection by the discharging driving plate 204.
