[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-2 This embodiment provides a fruit sugar content testing tray, including a tray body 1, a fruit support plate 2, and a light-proof sealing ring 3. The tray body 1 is a cylindrical structure with an open top. A sugar content testing window 101 is provided at the center of the bottom of the tray body 1. The light-proof sealing ring 3 is installed inside the bottom of the tray body 1 and is located outside the sugar content testing window 101. The light-proof sealing ring 3 is a hollow annular structure. The fruit support plate 2 is installed on the top of the tray body 1. The fruit support plate 2 is a circular structure. A through hole 201 is provided at the center of the fruit support plate 2. The tray body 1 and the fruit support plate 2 are made of plastic. The through hole 201 is coaxially arranged with the sugar content testing window 101. The diameter of the through hole 201 is larger than the diameter of the sugar content testing window 101. In use, the tray is installed on a fruit testing conveyor line, and the fruit to be tested is placed on the fruit support plate 2. The fruit portion passes through the through-hole 201 for positioning on the tray, and abuts against the light-proof sealing ring 3 to seal the fruit detection area from light. A fruit sugar content device is installed on the fruit detection conveyor line. The fruit sugar content device can be a near-infrared sugar content detector or other fruit sugar content measuring equipment. The near-infrared sugar content detector utilizes the fact that different sugars have different absorption characteristics for specific wavelengths of light after near-infrared light penetrates the fruit skin. The sugar content is estimated by analyzing the reflection or transmission spectrum data. This is existing technology and will not be elaborated on here. When the tray is transported to the fruit sugar content device, the detection light of the fruit sugar content device passes through the sugar content detection window 101 to detect the fruit sugar content, which can greatly improve the efficiency of fruit sugar content detection. The detection is completed during the fruit transportation and packing process. Moreover, the tray has a simple structure, low manufacturing cost, and is suitable for mass production.

[0022] In this embodiment, the height of the top outer side of the fruit support plate 2 gradually decreases towards the center. Multiple limiting claws are evenly spaced along the circumferential direction on the inner wall of the through hole 201 of the fruit support plate 2. Through this structural design, the top of the fruit support plate 2 presents a shape with a high edge and a central point, which is adapted to the shape of the fruit. The limiting claws help to better fix the fruit on the fruit support plate 2.

[0023] In this embodiment, a sealing ring positioning groove 102 is provided at the bottom of the tray body 1 and outside the sugar content detection window 101. The light leakage prevention sealing ring 3 is installed inside the sealing ring positioning groove 102 to position and assemble the light leakage prevention sealing ring 3 with the tray body 1, which facilitates the disassembly and replacement of the light leakage prevention sealing ring 3.

[0024] In this embodiment, a positioning structure is provided between the fruit support plate 2 and the tray body 1. The positioning structure includes a support plate positioning groove 103 annularly formed at the top of the tray body 1. An assembly plate 202 is fixedly connected to the bottom of the fruit support plate 2. The assembly plate 202 is integrally formed with the fruit support plate 2 and is aligned and inserted into the support plate positioning groove 103. The positioning structure also includes multiple limiting strips 104 fixedly connected at equal intervals along the circumferential direction of the inner wall of the tray body 1. A limiting groove 203 for the limiting strips 104 to be inserted is provided on the side wall of the assembly plate 202. When assembling the fruit support plate 2 and the tray body 1, the assembly plate 202 of the fruit support plate 2 is aligned and installed into the support plate positioning groove 103 of the tray body 1, and the limiting strips 104 are aligned and inserted into the limiting groove 203 to complete the assembly of the fruit support plate 2 and the tray body 1. This facilitates the disassembly and replacement of the fruit support plate 2, allowing for the replacement of fruit support plates 2 with different sizes and specifications of through holes 201. It is suitable for the fixed placement of fruits of different specifications and types, and has high practicality.

[0025] Example 2: It is basically the same as Example 1, such as... Figure 3 and Figure 4 As shown, the difference is that its light-proof sealing ring 3 is fixedly connected to the fruit support plate 2. The light-proof sealing ring 3 is set on the outside of the through hole 201 of the fruit support plate 2, so that the light-proof sealing ring 3 can be replaced synchronously with the fruit support plate 2, thereby improving the light-proof sealing of the fruit detection part and improving the detection effect.

[0026] Working principle: In use, the tray is installed on the fruit detection conveyor line. The fruit to be tested is placed on the fruit support plate 2, with the fruit part passing through the through hole 201 for positioning on the tray. The fruit part abuts against the light-proof sealing ring 3. The tray and fruit are transported by the fruit detection conveyor line. When transported to the fruit sugar content device, the detection light of the fruit sugar content device passes through the sugar content detection window 101 to detect the fruit sugar content, which can greatly improve the fruit sugar content detection efficiency. The assembly plate 202 of the fruit support plate 2 is aligned and installed into the support plate positioning groove 103 of the tray body 1, and the limiting strip 104 is aligned and inserted into the limiting groove 203, which facilitates the assembly of the fruit support plate 2 and the tray body 1 and facilitates the disassembly and replacement of the fruit support plate 2. The light-proof sealing ring 3 is installed in the sealing ring positioning groove 102 for assembling the light-proof sealing ring 3 and the tray body 1, which facilitates the disassembly and replacement of the light-proof sealing ring 3. It is suitable for the fixed placement of fruits of different specifications and types and has high practicality.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
