Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of quantitative weighing equipment for fruits and vegetables, specifically a quantitative weighing device for fruits and vegetables. Background Technology
[0002] In the sale and packaging of fruits and vegetables, it is often necessary to weigh them quantitatively, thus requiring the use of quantitative weighing equipment. Utility model patent application number CN202320909429.7 discloses a quantitative weighing device for fruits and vegetables. Both support plates are equipped with height-adjusting components. In this utility model, the blocking rod effectively prevents excessively large fruits and vegetables from falling into the bottom frame, affecting the accuracy of the weighing value. Simultaneously, when fruits and vegetables fall into the bottom frame and reach the required weight, they will press against the support plate. The carrier plate rotates downwards, causing fruits and vegetables that have reached the expected weight to fall off for the next packaging step. According to the publicly available technical solution, existing quantitative weighing equipment for fruits and vegetables has two main problems. First, when weighing fruits and vegetables, the electronic scale is prone to tilting, which can lead to inaccurate weighing and compromise the accuracy of the weighing process. Second, when weighing longer fruits and vegetables (such as cucumbers, sugarcane, and loofah), the vegetables are prone to rolling or even falling off the tray, which can compromise the safety of the weighing process.
[0003] Therefore, how to design a quantitative weighing device for fruits and vegetables has become a problem we need to solve. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quantitative weighing device for fruits and vegetables to solve the problems mentioned in the background technology. This utility model is reasonably designed, convenient to use, and suitable for quantitative and accurate weighing of fruits and vegetables.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative weighing device for fruits and vegetables, comprising an electronic scale and a tray. A positioning component is installed on the top of the electronic scale, the positioning component comprising a guide frame and a protective frame. A horizontal component is installed on the tray, the horizontal component comprising a circular sleeve and an inner cavity. A calibration component is installed on the inner cavity, the calibration component comprising a float and a crosshair. A protective component is installed on the tray, the protective component comprising a baffle and a rotating shaft. A support component is installed on the rotating shaft, the support component comprising a support rod and a spring.
[0006] Furthermore, the bottom of the tray is placed on top of the electronic scale, the guide frame is welded to the top of the electronic scale, the protective frame is welded to the bottom of the tray, the protective frame is fitted over the outside of the guide frame, and the height of both the protective frame and the guide frame is less than the distance between the tray and the electronic scale.
[0007] Furthermore, the tray has an opening at its center, and the sleeve is welded to the inner wall of the opening, with the top of the sleeve flush with the inner wall of the bottom of the tray.
[0008] Furthermore, the inner cavity is located inside the circular sleeve, and the height at the center of the inner cavity is greater than the height around the perimeter of the inner cavity. The inner cavity is filled with purified water.
[0009] Furthermore, the float is placed inside the inner cavity, the cross mark is engraved on the top of the float, the top of the circular sleeve is provided with an angle mark, and the circular sleeve is made of transparent material.
[0010] Furthermore, notches are provided on both sides of the tray, and the baffle is secured to the outer side of the tray, with the baffle located outside the notch.
[0011] Furthermore, one end of the rotating shaft is welded to one end of the baffle, and the other end of the rotating shaft passes through the side wall of the tray and extends to the inside of the tray.
[0012] Furthermore, the top end of the support rod is welded to the bottom of the other end of the rotating shaft, and one side of the bottom end of the support rod is connected to the inner wall of the tray by a spring. The baffles are symmetrically distributed on both sides of the notch.
[0013] Beneficial effects: 1. When using this quantitative weighing device for fruits and vegetables, the electronic scale is placed on the weighing platform. When the electronic scale tilts, the circular plate on the tray will also tilt, which in turn will cause the inner cavity to tilt. The float, due to the buoyancy of the pure water, will always be at the top of the inner cavity, keeping the float away from the center of the inner cavity. By using the cross mark on the float to correspond to the position of the inclination mark, the direction and angle of the electronic scale's tilt can be determined, allowing for appropriate height adjustments. Once the cross mark on the float is aligned with the center of the inclination mark, both the electronic scale and the tray can be adjusted to be completely level, avoiding weighing deviations caused by the tilt of the electronic scale and ensuring the accuracy of fruit and vegetable weighing.
[0014] 2. When weighing fruits and vegetables, this quantitative weighing device places the fruits and vegetables on a tray and weighs them using an electronic scale. When weighing longer fruits and vegetables (such as sugarcane, cucumbers, and stalks), the bottom of the longer fruits and vegetables is placed on top of the baffle. Under the influence of gravity, the baffle rotates via a pivot, causing the support rod to rotate. The support rod compresses the spring, causing the baffle to rotate downwards, thus supporting the bottom of the longer fruits and vegetables on the tray. The notch also limits the length of the longer fruits and vegetables, preventing them from rolling on the tray and thus preventing them from falling, ensuring the safety of the fruits and vegetables.
[0015] 3. This quantitative weighing device for fruits and vegetables is reasonably designed, highly efficient and convenient to use, and suitable for the quantitative and accurate weighing of fruits and vegetables. Attached Figure Description

[0021] 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.
[0022] Please see Figures 1 to 4This utility model provides a technical solution: a quantitative weighing device for fruits and vegetables, including an electronic scale 1 and a tray 2. A positioning component is installed on the top of the electronic scale 1, the positioning component including a guide frame 3 and a protective frame 4. A horizontal component is installed on the tray 2, the horizontal component including a circular sleeve 5 and an inner cavity 6. A calibration component is installed on the inner cavity 6, the calibration component including a float 7 and a crosshair 9. A protective component is installed on the tray 2, the protective component including a baffle 11 and a rotating shaft 12. A support component is installed on the rotating shaft 12, the support component including a support rod 13 and a spring 14. Notches 10 are provided on both sides of the tray 2. The baffle 11 is engaged with the outer side of the tray 2, the baffle 11 being located outside the notch 10. One end of the rotating shaft 12 is welded to one end of the baffle 11, and the other end of the rotating shaft 12 passes through the side wall of the tray 2 and extends to... Inside the tray 2, the top of the support rod 13 is welded to the bottom of the other end of the rotating shaft 12. One side of the bottom end of the support rod 13 is connected to the inner wall of the tray 2 through a spring 14. The baffles 11 are symmetrically distributed on both sides of the notch 10. When weighing fruits and vegetables, the fruits and vegetables are placed on the tray 2 and weighed by the electronic scale 1. When it is necessary to weigh longer fruits and vegetables (such as sugarcane, cucumber, silk stalks, etc.), the bottom of the longer fruits and vegetables is placed on the top of the baffle 11. After being subjected to gravity, the baffle 11 will drive the support rod 13 to rotate through the rotating shaft 12. The support rod 13 compresses the spring 14 and causes the baffle 11 to rotate downward, so that the bottom of the longer fruits and vegetables is supported on the tray 2. The notch 10 limits the length of the longer fruits and vegetables, preventing them from rolling on the tray 2 and thus preventing them from falling, ensuring the safety of the fruits and vegetables.
[0023] In this embodiment, the bottom of the tray 2 is placed on top of the electronic scale 1, the guide frame 3 is welded to the top of the electronic scale 1, and the protective frame 4 is welded to the bottom of the tray 2. The protective frame 4 is fitted over the outside of the guide frame 3. The height of both the protective frame 4 and the guide frame 3 is less than the distance between the tray 2 and the electronic scale 1. An opening is provided at the center of the tray 2, and a circular sleeve 5 is welded to the inner wall of the opening. The top of the circular sleeve 5 is flush with the inner wall of the bottom of the tray 2. An inner cavity 6 is opened inside the circular sleeve 5, and the height at the center of the inner cavity 6 is greater than the height of the perimeter of the inner cavity 6. The inner cavity 6 is filled with purified water. A float 7 is placed inside the inner cavity 6, and a cross mark 9 is engraved on the top of the float 7. An oblique opening is provided at the top of the circular sleeve 5. The circular sleeve 5, made of transparent material, is used when the electronic scale 1 is placed on the weighing platform. When the electronic scale 1 tilts, the circular plate 5 on the tray 2 will also tilt, causing the inner cavity 6 to tilt as well. The float 7, due to the buoyancy of the pure water, is always located at the top of the inner cavity 6, keeping it away from the center of the inner cavity 6. By using the cross mark 9 on the float 7 to correspond to the position of the inclination mark 8, the tilt direction and angle of the electronic scale 1 can be determined, allowing for appropriate height adjustments. Once the cross mark 9 on the float 7 is aligned with the center of the inclination mark 8, both the electronic scale 1 and the tray 2 can be adjusted to be completely level, preventing weighing deviations caused by the tilt of the electronic scale 1 and ensuring the accuracy of weighing fruits and vegetables.
[0024] When using this quantitative weighing device for fruits and vegetables, the electronic scale 1 is placed on the weighing platform. When the electronic scale 1 tilts, the circular plate 5 on the tray 2 will also tilt, causing the inner cavity 6 to tilt as well. The float 7, due to the buoyancy of the pure water, will always be at the top of the inner cavity 6, keeping it away from the center. By using the crosshair 9 on the float 7 to correspond to the inclination mark 8, the direction and angle of the tilt of the electronic scale 1 can be determined, allowing for appropriate height adjustments. Once the crosshair 9 on the float 7 is aligned with the center of the inclination mark 8, both the electronic scale 1 and the tray 2 are perfectly level, preventing weighing deviations caused by the tilt of the electronic scale 1. To ensure the accuracy of fruit and vegetable weighing, the fruits and vegetables are placed on tray 2 and weighed using electronic scale 1. When weighing longer fruits and vegetables (such as sugarcane, cucumbers, and stalks), the bottom of the longer fruits and vegetables is placed on top of baffle 11. After being subjected to gravity, baffle 11 will rotate via pivot 12, causing support rod 13 to rotate. Support rod 13 compresses spring 14 and causes baffle 11 to rotate downward, so that the bottom of the longer fruits and vegetables is supported on tray 2. The notch 10 limits the length of the longer fruits and vegetables, preventing them from rolling on tray 2 and thus preventing them from falling, ensuring the safety of the fruits and vegetables.
