[0002] Currently, cities across China are strengthening enforcement of regulations regarding food waste management, incorporating the collection, transportation, and disposal of food waste into the routine supervision of environmental protection departments. Food waste trucks typically weigh the waste in the bins before loading.

[0003] A search revealed Chinese Patent Publication No. CN211401397U, which discloses an intelligent garbage bin weighing scale. The scale includes a weighing body equipped with a weighing sensor. The weighing body employs a suspended upper and lower structure. The lower structure is composed of a keel structure, with protective bolts located at the four corners of the lower structure on the surface of the circumferential keel. A balance base is located at the bottom of the circumferential keel. The weighing body has an upper structure arranged parallel to the lower structure, comprising keel units and a steel plate structure arranged on top of the keel units. A weighing sensor is located in the middle of the weighing body, positioned between the upper and lower structures. Obstructions are provided on the left, right, and front edges of the steel plate structure.

[0004] Existing garbage bin weighing devices lack lifting and front-to-back position adjustment functions, limiting their applicability. Furthermore, their guiding and positioning functions are relatively simple.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a weighing device for kitchen waste, making it more valuable for industrial use. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a weighing device for kitchen waste.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A weighing device for food waste includes a lifting component and a weighing component;

[0009] The lifting assembly includes a motion platform, on which a lifting frame is mounted. A lifting motor module mounted on top of the lifting frame drives the lifting frame to move vertically. A hanger is mounted on the right side of the lifting frame via a robotic arm.

[0010] The weighing assembly, from bottom to top, includes a base and a weighing platform, with a weighing sensor installed in the middle of the weighing platform.

[0011] Guide sliders are installed at the bottom of the base near the left and right sides. Guide rails distributed along the front and back direction are set on the ground directly below the guide sliders. The guide sliders move along the front and back direction within the guide rails below. Fixed feet are installed at the four opposite corners of the base.

[0012] Rear limit blocks are installed on the bases on both the left and right sides behind the weighing platform, and front guide blocks are installed on the bases on both the left and right sides in front of the weighing platform.

[0013] As a further improvement of this utility model, the lifting frame is slidably installed on the lifting frame in the vertical direction.

[0014] As a further improvement of this utility model, guide rods distributed along the vertical direction are installed on both the front and rear sides of the lifting frame, and guide wheels are installed on the lifting frames on both the left and right sides of the guide rods. The two guide wheels are respectively connected to the guide grooves opened along the vertical direction on the inner side of the guide rods.

[0015] As a further improvement of this utility model, several pads are installed on the hanger.

[0016] As a further improvement of this utility model, the pad is an elastic block structure.

[0017] As a further improvement of this utility model, the rear limiting block has an L-shaped structure and is mounted on the base through the rear locking block at the bottom.

[0018] As a further improvement of this utility model, the front guide block is a plate-shaped structure distributed along the front-rear direction and is mounted on the base by the front locking block at the bottom.

[0019] As a further improvement of this utility model, a stop block is installed on the rear side inside the guide rail.

[0033] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] The first embodiment of this utility model:

[0036] like Figure 1 The weighing device for kitchen waste in this embodiment mainly includes a lifting component and a weighing component 7. The lifting component can lift and transport the garbage bin containing kitchen waste to the weighing component 7 on one side for weighing.

[0037] like Figure 1 and Figure 2 The lifting assembly in this embodiment mainly includes a motion platform 1, a lifting frame 2, a lifting motor module 3, a lifting frame 4, and a hanger 6.

[0038] The lifting frame 2 serves as the main structure of the lifting assembly. A motion platform 1 is installed on the ground below the lifting frame 2. The motion platform 1 can realize one or more combinations of forward and backward movement, left and right movement, and rotational movement according to the actual situation. The above-mentioned movement structure and principle are all existing technologies in this field.

[0039] A lifting motor module 3 is installed on the top of the lifting frame 2. This module drives the lifting frame 4 to move vertically along the lifting frame 2. A hanger 6 is installed on the right side of the lifting frame 4 via a robotic arm 5, which can lift the food waste bin. This automatically lifts the food waste bin from the ground to the weighing platform 702, reducing manual handling and labor intensity, making it especially suitable for large-capacity waste bin scenarios.

[0040] During the lifting process of the food waste bin, the lifting bracket 6 rises from bottom to top until it engages with the top end of the food waste bin. Alternatively, the lifting bracket 6 can be designed as a movable gripper structure common in this field, which can be used for lifting various models of food waste bins.

[0041] Among them, several pads 8 are installed on the hanger 6 to reduce damage to the surface of the kitchen waste bin. The pads 8 are elastic block structures (such as rubber blocks or silicone blocks).

[0042] Furthermore, the lifting frame 4 moves vertically along the lifting frame 2 under the drive of the lifting motor module 3. A guide structure for the lifting frame 4 during its movement is installed between the lifting frame 2 and the lifting frame 4. The vertical movement of the lifting frame 4, in conjunction with the robotic arm, ensures that the container is placed stably on the weighing platform 702, avoiding swaying errors caused by manual handling.

[0043] The guide structure mainly includes guide rods installed on the front and rear sides of the hoist frame 2 and distributed along the vertical direction, and guide wheels installed on the left and right sides of the guide rods on the hoist frame 4. Guide grooves distributed along the vertical direction are opened on the side of the guide rod facing the guide wheel, and the two guide wheels are respectively connected to the inner guide grooves.

[0044] like Figure 3 The weighing component 7 in this embodiment mainly includes a base 701, a weighing platform 702, and a weighing sensor 703. The weighing platform 702 is fixedly installed on the base 701. A weighing sensor 703 for weighing the food waste bin is installed in the weighing platform 702. The weighing sensor 703 is a common weighing mechanism in the prior art. When the food waste bin is placed on the weighing platform 702, it is weighed by the weighing sensor 703, and the weighed value can be displayed on an externally electrically connected display.

[0045] When the food waste bin is lifted by the hanger 6 and placed on the weighing platform 702, the food waste bin is placed on the weighing platform 702 from front to back.

[0046] Front guide blocks 709 are respectively installed on the left and right sides of the front of the weighing platform 702. The bottom of the front guide blocks 709 is locked to the base 701 by front locking blocks 710 and bolts. The front guide blocks 709 are plate-shaped structures distributed along the front-back direction. When the kitchen waste bin initially enters the front of the weighing platform 702, it is guided by the front guide blocks 709.

[0047] Rear limit blocks 707 are respectively installed on the left and right sides of the rear of the weighing platform 702. The bottom of the rear limit block 707 is locked to the base 701 by a rear locking block 708 and bolts. The rear limit block 707 has an L-shaped structure. The first end of the L-shaped structure is parallel to the front guide block 709, and the second end of the L-shaped structure is located behind and perpendicular to the first end of the L-shaped structure. When the kitchen waste bin enters the rear of the weighing platform 702, it is first guided by the first end of the L-shaped structure, and then the rear limit is achieved by the second end of the L-shaped structure.

[0048] In summary, the cooperation between the front guide block 709 and the rear limit block 707 ensures precise positioning of the container in both front-to-back and left-to-right directions, ensuring that the center of gravity is strictly aligned with the center of the weighing sensor and reducing eccentricity errors. The active guidance (front guide block 709) and the limiting (rear limit block 707) create a dual constraint, resulting in more reliable positioning.

[0049] The second embodiment of this utility model:

[0050] like Figure 3 The base 701 is structurally adapted to the guide slider 706 and the guide rail 705, allowing for flexible movement and precise positioning.

[0051] 1. Adaptability of forward and backward movement: The bottom of the base 701 is connected to the guide rail 705 on the ground through the guide slider 706, which can move in the forward and backward direction to adapt to the position adjustment of different garbage disposal points. It is especially suitable for scenarios with compact space such as kitchens where equipment needs to be flexibly arranged.

[0052] A stop is installed on the rear side of the guide rail 705 to limit the movement of the guide slider 706 on the base 701. Furthermore, this stop can be detachably installed within the guide rail 705, allowing for more flexible adjustment.

[0053] 2. Stability of fixed support feet: The fixed support feet 704 at the four corners of the base 701 can be fixed after positioning. Combined with the guiding function of the guide rail 705, it takes into account both the flexibility of movement and the stability during weighing.

[0054] This utility model, through three core innovations—enhancing automation, mobility flexibility, and multi-dimensional positioning accuracy—better meets the needs of "efficient handling, accurate weighing, and flexible layout" in the kitchen and dining scenarios. It is especially suitable for scenarios such as canteens and restaurant kitchens that require frequent handling of bulk waste, and has higher engineering application value and market competitiveness.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0056] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
