[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] In the related art, a balance scale is a commonly used weighing device, which is composed of a scale plate, a crossbeam, a balance nut, a scale, a dial, a pointer, a knife edge, a base, a ruler, a sliding weight, a weight, etc. The use of a balance scale is very simple. There is a small plate at each end of the lever. The object to be weighed is placed on the left end, and the weight is placed on the right end. There is a pointer in the center of the lever. When the two ends are balanced, the mass of the two ends is equal, and the mass of the object can be measured.

[0038] Balance scales are commonly used weighing equipment. The weighing pans of balance scales are mostly round. After the materials are weighed, they need to be poured into small bags for packaging. During this process, it is difficult to operate and easy to drop, which greatly reduces production efficiency.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, in order to solve the above technical problems, an embodiment of the present application provides a weighing pan, which includes a pan body 200 and a tube body 100, wherein the tube body 100 and the pan body 200 are connected, and the tube body 100 is tapered in a direction away from the pan body 200; wherein the side wall of the tube body 100 has a notch 110, and the notch 110 extends from the end surface of the tube body 100 away from the pan body 200 in a direction close to the pan body 200, and the side wall of the tube body 100 is elastic.

[0040] In this embodiment, the core of the scale pan lies in its unique integrated structure of the pan body 200 and the tube body 100. This design not only maintains the original load-bearing function of the scale pan, but also provides a smooth transition channel for material transfer through the introduction of the tube body 100, avoiding the risk of scattering when directly dumping.

[0041] The tube body 100 is designed to be tapered in the direction away from the tray body 200. This structure not only provides a clear material guide for the operator visually, but also effectively controls the material flow rate through the gradually reduced caliber, reduces splashing, and improves the accuracy of pouring. In addition, the gradually reduced caliber can be used to insert the packaging bag to further reduce the risk of splashing.

[0042] Of course, the notch 110 on the side wall of the tube body 100 starts from the end face of the tube body 100 away from the disc body 200 and extends toward the disc body 200. This design facilitates cleaning and reduces the probability of jamming during the flow of materials. In addition, by utilizing the notch 110 and the elasticity of the side wall of the tube body 100, the caliber of the tube body 100 can be changed by swinging the tube body 100 through the elastic deformation of the tube body 100, so as to adapt to packaging bags of various calibers.

[0043] Exemplarily, the tube body 100 is a thin-walled elastic tube, such as a plastic tube, a thin-walled metal tube, etc., which is not specifically limited here.

[0044] In summary, the scale pan design of the present application significantly improves the convenience and efficiency of material transfer and effectively reduces the risk of material scattering through the innovative combination of an integrated structure, a tapered tube body 100, a side wall notch 110 and an elastic side wall. It is very suitable for production environments that require frequent precise weighing and material packaging, such as the pharmaceutical and food processing industries, and is of great significance for improving production efficiency and reducing waste.

[0045] like Figure 2 As shown, in some embodiments, the bottom of the tray 200 is configured as a planar structure.

[0046] In these embodiments, the bottom of the pan body 200 is designed with a planar structure. The planar structure of the bottom of the pan body 200 can provide a stable supporting surface, so that the scale pan is more stable when placed on various workbenches or platforms, reducing the risk of shaking or tipping due to imbalance, especially when placing heavy objects or performing precision weighing operations, stability is crucial.

[0047] The flat bottom design has no grooves or complex structures, which facilitates quick and thorough cleaning. After handling materials that are easy to adhere to or penetrate, such as powders and liquids, the flat structure can reduce residues and is easy to rinse with water or wipe with detergent, ensuring hygiene standards and meeting the strict cleanliness requirements of industries such as food and medicine.

[0048] In addition, for applications that require high-precision weighing, especially weighing medicines, the flat bottom can ensure that the center of gravity of the weighed object is stably located in the center of the scale pan, reducing uneven weight distribution or center of gravity offset caused by the bottom shape, thereby improving weighing accuracy and repeatability.

[0049] Illustratively, the disc body 200 and the tube body 100 are formed into a spoon-shaped structure.

[0050] like Figure 3 As shown, in some embodiments, the tray body 200 has a feed opening 210 , and the slot 110 penetrates through a side wall of the feed opening 210 .

[0051] In these embodiments, a feed port 210 is intentionally added to the design of the weighing pan, and the slot 110 is cleverly designed to penetrate the side wall of the feed port 210. The provision of the feed port 210 makes material addition more convenient and directional, and the user can directly introduce the material into the weighing pan through the feed port 210. The slot 110 penetrating the side wall of the feed port 210 can further increase the area of ​​the feed port 210, making it easier to add materials.

[0052] In addition, the through slot 110 design is not only conducive to the introduction of materials, but also convenient for cleaning after use, helping water or air flow to penetrate into the interior of the scale pan, quickly removing residual materials, reducing cleaning dead corners, and maintaining the hygiene of the scale pan, meeting high cleaning standards such as food safety and pharmaceutical production.

[0053] like Figure 3 As shown, in some embodiments, one end of the tube body 100 facing away from the disc body 200 is configured as a tip 120 .

[0054] That is to say, in practical applications, a tip 120 is provided at one end of the tube body 100 away from the disc body 200 to guide the tube body 100 and facilitate the insertion of the tube body 100 into the packaging bag.

[0055] For example, one end of the tube body 100 away from the disc body 200 extends away from the notch 110 to form a tip 120 , and the tip 120 is rounded to avoid scratching the user.

[0056] like Figure 4 As shown, in some embodiments, the side walls on both sides of the slot 110 are respectively provided with mounting ear plates 300 , and the mounting ear plates 300 are located on a side of the slot 110 away from the tube body 100 .

[0057] In these embodiments, mounting ear plates 300 are additionally provided on the side walls on both sides of the slot 110, and these mounting ear plates 300 are arranged on the side of the slot 110 away from the tube body 100. The mounting ear plates 300 are provided for users to hold. The user can control a pair of mounting ear plates 300 to move closer to or away from each other to change the width of the slot 110, thereby achieving the effect of adjusting the diameter of the tube body 100 to adapt to packaging bags of different sizes.

[0058] In addition, the mounting ear plate 300 is designed to be able to install various accessories or fixings, such as hooks, chains, fixing screws, etc., which provides more flexibility for the use of the scale plate. For example, the ear plate can be used to mount small cleaning tools for easy cleaning and maintenance; or the scale plate can be fixed on an automated assembly line to achieve fast and accurate material transfer.

[0059] For example, the mounting ear plate 300 is integrated with the pipe body 100. Alternatively, the mounting ear plate 300 is assembled to the pipe body 100 by gluing or screwing.

[0060] like Figure 5 and Figure 6 As shown, in some embodiments, the scale pan further includes an adjusting member, which is connected to the pan body 200 , and the adjusting member can adjust the width of the notch 110 .

[0061] In these embodiments, an adjustment member is introduced into the scale pan design to control the width of the slot 110. This design innovation brings significant flexibility and practicality to the use of the scale pan. By adjusting the width of the slot 110, the scale pan can adapt to materials or packaging bags of different sizes and shapes. Whether it is powder, granules or blocks, a suitable opening size can be found to ensure smooth passage of materials, reduce blockage or overflow, and improve the versatility of weighing and transfer.

[0062] Adjusting the width of the slot 110 also means that the speed and amount of material outflow can be controlled. This design is particularly important for operations that require precise control of the feeding speed, as it can help users make precise adjustments to avoid inaccurate metering or bag damage caused by rapid material outflow.

[0063] In addition, when the scale pan needs to be cleaned, the larger width of the slot 110 makes it easier to use cleaning tools to deeply clean the inside, while the smaller width helps to reduce material residue after use. The combination of the two can be adjusted according to actual conditions to achieve fast and effective cleaning.

[0064] Of course, the addition of the adjustment parts allows the operator to quickly adjust the scale pan according to actual work needs without having to replace the scale pan or perform complicated operations, thereby improving work efficiency.

[0065] like Figure 5 and Figure 6 As shown, in some embodiments, the adjusting member includes an adjusting bolt 400, one of the side walls on both sides of the slot 110 is provided with a through hole, and the other side wall on both sides of the slot 110 is provided with a threaded hole, and the adjusting bolt 400 is passed through the through hole and threadedly connected to the hole wall of the threaded hole.

[0066] In these embodiments, the design of using the adjusting bolt 400 as an adjusting member to control the width of the slot 110 demonstrates the significant advantages of the scale plate in terms of flexibility and adjustability. The adjusting bolt 400 is combined with the through hole and the threaded hole on the side wall, allowing the user to accurately adjust the width of the slot 110 by rotating the adjusting bolt 400. This adjustment method is simple and direct, and the operator can easily fine-tune the size of the slot 110 according to actual needs, ensuring that the control of material flow reaches the optimal state.

[0067] The threaded connection ensures stability and reliability during the adjustment process. When the adjustment bolt 400 is screwed into the threaded hole, the mechanical locking effect formed can withstand a certain working stress, avoid accidental loosening due to external force during use, and ensure the fixity of the adjustment position.

[0068] Obviously, this design makes the adjustment operation simple and quick, usually without special tools, and only a wrench is needed to adjust the width of the slot 110. At the same time, when it is necessary to clean or inspect the inside of the scale pan, the adjustment bolt 400 can also be quickly disassembled for easy maintenance.

[0069] Due to the wide adjustment range of the adjusting bolt 400, this design enables the scale pan to adapt to materials of different sizes, shapes and flow characteristics, broadening its application field. Whether it is fine particles or large solids, the appropriate passing size can be found through adjustment. Or, it is suitable for packaging bags of different sizes. By quickly and accurately adjusting the size of the notch 110, the waiting and adjustment time in the material handling process is reduced, and the production efficiency and process continuity are improved. This design advantage is more significant, especially in a production environment where materials or packaging specifications need to be frequently changed.

[0070] Of course, in other embodiments, the adjusting member may also be an elastic clamping jaw with different elastic forces, and the outer diameter of the tube body 100 can be changed by replacing the elastic clamping jaw. In other words, the elastic deformation ability of the tube body 100 is used in conjunction with the elastic clamping jaw. The larger the elastic clamping jaw, the smaller the outer diameter of the tube body 100. After removing or replacing the elastic clamping jaw with less elastic force, the tube body 100 returns to the initial outer diameter state under the action of its own elastic deformation.

[0071] like Figure 5 and Figure 6 As shown, in some embodiments, the through hole and the threaded hole are respectively disposed on the mounting ear plate 300 on the corresponding side, and the position of the mounting ear plate 300 is configured to enable the adjusting bolt 400 to be located outside the pipe body 100 .

[0072] In these embodiments, by designing through holes and threaded holes on the mounting ear plate 300 and ensuring that the adjusting bolt 400 is located outside the tube body 100, the operator does not need to touch or interfere with the inside of the tube body 100 when adjusting the width of the slot 110, thereby avoiding contamination or damage to the material or the inside of the scale pan during the adjustment process.

[0073] Integrating through holes and threaded holes on the mounting ear plate 300 not only provides a stable basis for the adjustment function, but also avoids drilling holes in the weighing pan and reduces the risk of leakage.

[0074] Obviously, by arranging the adjustment mechanism outside the weighing pan, especially by using the mounting ear plate 300 to realize this design, the occupation of the internal space of the tube body 100 of the weighing pan is reduced, and the impact on the unloading of the weighing pan is reduced.

[0075] In some embodiments, the tube body 100 and the disk body 200 are integrally configured, the tube body 100 is configured as a thin-walled structure, and the disk body 200 is configured as a thin-walled structure.

[0076] In these embodiments, the weighing pan design adopts a thin-walled structure in which the tube body 100 and the pan body 200 are integrated, which greatly reduces the weight of the weighing pan. The lightweight design makes the weighing pan easier to carry and operate, reduces energy consumption during transportation and use, and is particularly suitable for occasions that require frequent movement or operation.

[0077] Moreover, it is beneficial for the elastic deformation of the tube body 100. For example, the tube body 100 and the plate body 200 are both made of plastic.

[0078] In some embodiments, the present application also provides a balance scale, which includes a weight pan and a weighing pan as described in any one of the above embodiments.

[0079] Since the weighing pan has the above technical effects, the balance scale including the weighing pan should have the same technical effects, which will not be described in detail. The weight pan and the weighing pan are respectively placed on both sides of the balance scale, the weight pan is used to place weights, and the weighing pan is used to place materials to be weighed.

[0080] Of course, in other embodiments, the scale pan can also be used for other weighing equipment, such as a beam scale and the like.

[0081] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0082] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0083] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
