[0002] Pizza dumplings are a type of food made primarily from high-gluten and low-gluten flour. During the production process, pizza dumplings need to be packaged according to a certain weight. In order to ensure uniform weight, the pizza dumplings must first be weighed to the appropriate weight before being sealed and packaged.
[0003] For example, Chinese patent CN220153698U discloses a weighing device for pizza dumpling processing, including: a weighing device body with a matching weighing pan; a push rod slidably disposed inside the weighing pan, and a scraper is mounted on the push rod; a second guide groove is formed on the side wall of the weighing pan, and a first guide groove is formed on the second guide groove, and a guide block installed on the end of the scraper is slidably disposed inside the first guide groove or the second guide groove.
[0004] The aforementioned weighing device for pizza dumpling processing still has certain shortcomings. It uses the sliding of a push rod to drive a scraper to scrape the bottom of the weighing pan. During the movement of the scraper, the guide block moves inside the first or second guide groove. When the guide block slides to the first guide groove above the second guide groove, the bottom of the scraper will not contact the bottom of the weighing pan, preventing the scraped material from being carried to the other side of the weighing pan when the scraper moves in the opposite direction, which is convenient for the operator to clean. However, when the scraper scrapes the material, some powder from the outside of the pizza dumpling may remain on the scraper, affecting the efficiency of powder cleaning. Therefore, this application proposes a weighing device for pizza dumpling processing to solve the above problems. Utility Model Content

[0010] Furthermore, the end of the discharge pipe away from the air pump is connected to the right side of the storage tank, and the filter plate is inclinedly arranged inside the storage tank.
[0011] Furthermore, the filter pad is movably attached to the inner wall of the weighing pan cavity, and the extraction tube is a flexible tube.
[0012] Furthermore, the weighing pan moves vertically inside the groove, and both strain sensors are installed on the inner bottom wall of the groove. The inner bottom wall of the groove has four positioning grooves, and the four positioning posts are welded to the bottom of the weighing pan and slide inside the four positioning grooves respectively.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figs. 1-2 This embodiment of a weighing device for processing pizza dumplings includes a weighing device body 1, a weighing pan 3 that slides vertically above the weighing device body 1, a filter pad 4 placed inside the weighing pan 3, a cleaning mechanism 2 for extracting pizza dumpling powder inside the weighing device body 1, and a groove formed on the upper surface of the weighing device body 1.
[0022] A display screen 7 is provided on the front side of the weighing device body 1. An operable button is provided on the left side of the display screen 7 and on the weighing device body 1. The weighing pan 3 moves vertically inside the groove. Two strain gauge sensors 5 are both set on the inner bottom wall of the groove. Four positioning grooves are opened on the inner bottom wall of the groove. Four positioning columns 6 are welded to the bottom of the weighing pan 3 and slide inside the four positioning grooves respectively.
[0023] Understandably, the produced pizza dumplings are placed inside the weighing pan 3 and on the upper surface of the filter pad 4. At this time, the weighing pan 3 begins to move downward and squeeze the strain gauge sensor 5. When the strain gauge sensor 5 is squeezed and bent, its resistance value changes. By measuring the change in resistance value, the weight of the produced pizza dumplings can be calculated.
[0024] Please see Figs. 3-4 In this embodiment, the cleaning mechanism 2 includes multiple suction slots 201 formed on the bottom wall of the weighing pan 3. An air pump 202 is provided on the right side of the weighing device body 1. The suction end of the air pump 202 is connected to a suction pipe 203, and the discharge end of the air pump 202 is connected to a discharge pipe 204. A storage box 205 is fixed on the front side of the weighing device body 1. A box cover is provided on the front side of the storage box 205. A filter plate 206 is provided inside the storage box 205. The box cover can be opened to take out the filter plate 206 inside.
[0025] Multiple suction slots 201 are connected to a connecting slot at the bottom of the weighing pan 3. The end of the extraction pipe 203 furthest from the air pump 202 is fixed to the bottom of the weighing pan 3 via a flange and connected to the connecting slot. After measuring the pizza dumpling, it is removed. This may cause powder from the outside of the pizza dumpling to adhere to the outside of the filter pad 4. Therefore, the air pump 202 is activated, and the extraction pipe 203 generates a strong suction force on the multiple suction slots 201, drawing the powder from the outside of the pizza dumpling into the air pump 202 and transferring it to the inside of the storage tank 205. The discharge pipe 20... 4. The end away from the air pump 202 is connected to the right side of the storage box 205. The filter plate 206 is inclinedly set inside the storage box 205. The filter pad 4 is movably attached to the inner wall of the weighing pan 3. The extraction tube 203 is a flexible tube. When the powder on the outside of the pizza dumpling is drawn into the air pump 202 and transferred to the inside of the storage box 205, it is filtered and stored by the filter plate 206. Larger pizza dumpling pieces can be cleaned by picking up the filter pad 4. It has the advantages of quickly cleaning the powder on the outside of the pizza dumpling, which facilitates the subsequent weighing work.
[0026] It is understood that all electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned in this article are conventional and known devices.

[0028] The working principle of the above embodiments is as follows:
[0029] When the weighing device for pizza dumpling processing is needed, the produced pizza dumpling is placed inside the weighing pan 3 and on the upper surface of the filter pad 4. At this time, the weighing pan 3 begins to move downward and squeeze the strain gauge sensor 5. When the strain gauge sensor 5 is squeezed and bent, its resistance value changes. By measuring the change in resistance value, the weight of the produced pizza dumpling can be calculated. After the pizza dumpling is measured, it is taken out. The powder on the outside of the pizza dumpling may adhere to the outside of the filter pad 4. Therefore, the air pump 202 is started. The extraction tube 203 generates a large suction force on multiple suction slots 201 to draw the powder on the outside of the pizza dumpling into the air pump 202 and transfer it to the inside of the storage box 205. It is then filtered and stored by the filter plate 206. Larger pizza dumpling pieces can be cleaned by picking up the filter pad 4. It has the advantages of quickly cleaning the powder on the outside of the pizza dumpling, which facilitates subsequent weighing work.
