Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] refer to Figures 1-3 The present invention provides a material box 100, which is used in the shelf 200 of an automatic weighing vending machine, and includes a box body 10 and a bottom support 20.

[0033] The box body 10 includes a base plate 11 and side plates 12 disposed around the base plate 11.

[0034] The bottom bracket 20 is integrated into the base plate 11. The bottom bracket 20 has a protrusion protruding from the lower surface of the base plate 11. The material box 100 is installed such that the protrusion abuts against the weighing sensor 201 in the shelf 200 and the base plate 11 is suspended.

[0035] In this embodiment, the installation of the material box 100 can be completed by integrating the bottom bracket 20 into the bottom of the material box 100 and fixing the bottom bracket 20 to the weighing sensor 201. This effectively reduces the number of installation parts and makes the installation simple, thus reducing the installation time.

[0036] Furthermore, sheet metal processing is complex. Traditional sheet metal boxes require multiple processing steps such as stamping, bending, and welding, resulting in low material utilization and high costs associated with repeated mold development, making it difficult to meet the economic requirements of large-scale production.

[0037] In this embodiment, the box body 10 and the bottom support 20 are integrally formed by injection molding.

[0038] Specifically, the box body 10 and the bottom support 20 can be integrally molded from alloy plastic through injection molding, which effectively simplifies the manufacturing process, improves manufacturing efficiency, and reduces mass production costs.

[0039] Part of the side of the bottom bracket 20 extends downward to form a stop 21, which surrounds and forms a positioning area that matches the side end of the load cell 201.

[0040] Specifically, the existing installation and connection between the weighing sensor and the material box mostly relies on manual alignment, lacks positioning assistance structures, and is relatively cumbersome and unreliable.

[0041] refer to Figure 3 and Figure 4 In this embodiment, the bottom support 20 is rectangular and protrudes from the lower surface of the base plate 11. Three sides of the bottom support 20 extend vertically downwards to form flanges 21. These flanges 21 enclose and merge with the remaining open side to form a rectangular positioning area, thus forming a U-shaped open rectangular structure. Simultaneously, this positioning area matches the outer contour of the load cell 201's force-bearing end. When the bottom support 20 needs to be installed on the load cell 201, the open side of the positioning area is aligned with the force-bearing end side of the load cell 201, and the material box 100 is pushed accordingly. The positioning area assists in positioning the bottom support 20 at the force-bearing end of the load cell 201, achieving precise positioning during installation, effectively improving installation positioning accuracy, and reducing installation time.

[0042] The bottom bracket 20 has a connecting through hole 22, and the base plate 11 has a mounting hole 111 that communicates with the connecting through hole 22.

[0043] refer to Figure 4In this embodiment, the mounting hole 111 on the upper surface of the base plate 11 is connected to the connecting through hole 22, and the load cell 201 is provided with a threaded hole. After the bottom bracket 20 is positioned at the force-bearing end of the load cell 201 by the flange 21, the bottom end of the connecting through hole 22 is correspondingly abutted in the threaded hole of the load cell 201. The bottom bracket 20 can be connected to the load cell 201 simply by inserting a screw 115 through the mounting hole 111 and fixing it through the connecting through hole 22 and the threaded hole. The installation is simple and quick, further reducing the installation time.

[0044] Furthermore, the material box 100 is connected to the weighing sensor 201 via the bottom bracket 20, and is then used in the shelf 200 of the automatic weighing vending machine. Specifically, the automatic weighing vending machine has multiple product channels along its height, each channel has a shelf 200, and each shelf 200 can have multiple installation positions to install the material box 100, through which products are placed. Each installation position is equipped with a weighing sensor 201. By connecting the weighing sensor 201 to the bottom of the material box 100, the products in the material box 100 can be weighed. At the same time, each material box 100 in the shelf 200 also has a display screen, which displays the weight of the weighed products in the material box 100. The display screen can also display product information such as the product type in the material box 100.

[0045] refer to Figure 1 and Figure 2 The upper surface of the base plate 11 has an opening area 112 surrounding the mounting holes 111. The opening area 112 is detachably equipped with a matching cover plate 30. The opening area 112 has a guide groove 113 and a retaining groove 114 arranged opposite to each other. (Reference) Figure 5 The cover plate 30 is provided with a guide protrusion 31 and a buckle 32 corresponding to the guide groove 113 and the slot 114, respectively.

[0046] Specifically, the buckle 32 is a cantilever buckle, including a U-shaped elastic cantilever 321, a hook 322 disposed on the elastic cantilever 321, and a pressing boss 323. During assembly of the cover plate 30, the cover plate 30 is tilted so that the two guide protrusions 31 are aligned and placed in the two guide grooves 113, and the cover plate 30 is pushed along the guide grooves 113 until the guide protrusions 31 reach the end of the guide grooves 113. Subsequently, downward force is applied to deform the elastic cantilever 321 and embed it into the slot 114. The slot 114 has a horizontal section. When the hook 322 passes the critical point, it will be embedded into the horizontal section of the slot 114, thus completing the locking and fixing. During disassembly, force is applied by pressing the boss 323 to deform the elastic cantilever 321, causing the hook 322 to disengage from the critical point and correspondingly lift upward, thus completing the disassembly of the cover plate 30. The cover plate 30 can be quickly installed and removed through the cooperation between the guide groove 113 and the slot 114 with the guide protrusion 31 and the buckle 32.

[0047] Furthermore, the size of the cover plate 30 matches the size of the opening area 112, and the opening area 112 is in the form of a groove. After the cover plate 30 is installed on the base plate 11, it can completely cover the opening area 112, thereby shielding the mounting hole 111 and the screw 115 placed in the mounting hole 111, making the overall appearance more aesthetically pleasing and providing a protective effect.

[0048] The top of the side plate 12 is provided with a flange 121, and the outer surface of the side plate 12 is provided with a side reinforcing rib 122, which is connected to the flange 121.

[0049] Specifically, the base plate 11 and the side plates 12 surrounding the perimeter form a box 10. The opening edge of the box 10 is provided with a flange 121 as a reinforcing structure, and the outer surface of the side plates 12 on both sides and the back side is provided with side reinforcing ribs 122 to improve strength. At the same time, the flange 121 and the side reinforcing ribs 122 are connected to form a continuous support frame, which can further improve the strength of the box 10.

[0050] Furthermore, the flange 121 and the side reinforcing rib 122 can be integrally formed by injection molding, without the need for additional processing steps, thus avoiding the complexity and high cost of traditional metal sheet bending processes and effectively reducing the cost of mass production.

[0051] The bottom support 20 is located at the center of the lower surface of the base plate 11.

[0052] Specifically, the bottom bracket 20 is located at the center of the lower surface of the base plate 11 and directly abuts against the weighing sensor 201, which enables the vertical load generated by the weight of the product inside the box 10 to be transmitted to the weighing sensor 201 along the shortest path, effectively improving the weighing accuracy and response speed.

[0053] The lower surface of the base plate 11 is provided with a bottom reinforcing rib 116 surrounding the bottom support 20, and the bottom reinforcing rib 116 is a radial reinforcing rib. The bottom end of the side plate 12 extends from the base plate 11, one end of the bottom reinforcing rib 116 is connected to the bottom support 20, and the other end is connected to the side plate 12.

[0054] refer to Figure 3 The bottom reinforcing rib 116 is a radial reinforcing rib, which extends radially towards the side plate 12 from the bottom support 20 located at the center of the lower surface of the bottom plate 11, forming a continuous force transmission path from the center to the edge. This can avoid stress concentration in the central area, prevent local dents or cracks in the bottom plate 11, further improve the strength of the box, and improve the load-bearing performance.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
