Description

Technical Field

[0001] This utility model relates to the field of salted duck egg processing technology, specifically a salted duck egg sorting device. Background Technology

[0002] As is well known, salted duck eggs, as a traditional food, need to be graded by weight and quality during their production process to meet the standardized demands of the market. Currently, the sorting process mainly relies on manual sorting and fixed mechanical sorting.

[0003] However, manual sorting, which relies on manual weight estimation or simple weighing tools, is not only inefficient and labor-intensive, but also subject to subjective sorting standards. Furthermore, long-term exposure to salty environments can pose health risks. Although mechanical sorting equipment uses a combination of conveyor belts and weighing sensors, the sorting mechanism often employs semi-automatic push rod sorting, which has a complex transmission structure, slow sorting action, and difficulty in achieving high-speed continuous operation. At the same time, the feeding process often relies on vibratory feeders or manual placement, which can easily lead to stacking and jamming, further increasing the risk of damage.

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a salted duck egg sorting device.

[0006] (II) Technical Solution

[0008] To ensure that the weighing plate moves along a predetermined trajectory, the present invention is improved as follows: the sorting device includes a rotating rod and a translating block, the rotating rod passes through the cavity, the translating block is on the rotating rod and threadedly connected to it, the translating block is adapted to and slidably connected to the cavity, the upper side wall of the moving box is provided with a through hole, the translating block passes through the through hole and is slidably connected to it, and the weighing plate is connected to the translating block.

[0009] In order to achieve precise control of the start and stop of the sorting action and the stroke, the present invention has the following improvements: a rotating motor is provided on one side wall of the moving box, and the rotating rod passes through the moving box and is connected to the output end of the rotating motor.

[0010] To guide the duck eggs along a predetermined trajectory, this utility model improves upon the following: the auxiliary device includes a limit motor, an auxiliary rod, and a contact rod. The limit motor is located inside the weighing plate, the auxiliary rod passes through the upper side wall of the weighing plate and is connected to the output end of the limit motor, and the contact rod is located on one side of the auxiliary rod and is in contact with the weighing plate.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a salted duck egg sorting device, which has the following beneficial effects:

[0017] This salted duck egg sorting device is equipped with a sorting unit, a weighing plate, and multiple conveyor belts, forming a continuous conveying channel for seamless sorting of duck eggs. Simultaneously, a rotating motor drives a rotating rod, which in turn moves a translation block, causing the weighing plate to move. This precise displacement control ensures that the weighing plate moves synchronously with the translation block, allowing the duck eggs to accurately slide into the corresponding collection area according to a preset weight threshold.

[0025] 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.

[0026] Please see Figure 1-4A salted duck egg sorting device includes a movable box 8, characterized in that: multiple sets of parallel conveyor plates 1 are arranged on one side of the movable box 8, and a conveyor belt 2 adapted to the conveyor plate 1 is arranged on the conveyor plate 1; a cavity is provided inside the movable box 8, and a sorting device is arranged in the cavity; a weighing plate 9 is arranged on the upper side of the movable box 8, the weighing plate 9 is adapted to the conveyor belt 2, the weighing plate 9 is connected to the sorting device, a weighing system 10 is arranged at one end of the upper side wall of the weighing plate 9, and an auxiliary device for unloading is arranged at the other end; a connecting plate 5 is arranged on the side wall of the movable box 8 away from the conveyor plate 1, and a feeding device is arranged on the upper end of the connecting plate 5; the sorting device includes a rotating rod 12 and a translation block 13, the rotating rod 12 passing through the cavity, and the translation block 13 being threadedly connected to the rotating rod 12; the translation block 13 being threadedly connected to the rotating rod 12. The shift block 13 is adapted to and slidably connected to the cavity. The upper side wall of the moving box 8 is provided with a through hole. The shift block 13 passes through the through hole and is slidably connected to it. The weighing plate 9 is connected to the shift block 13. A rotating motor 11 is provided on one side wall of the moving box 8. The rotating rod 12 passes through the moving box 8 and is connected to the output end of the rotating motor 11. The auxiliary device includes a limit motor 14, an auxiliary rod 15, and a contact rod 16. The limit motor 14 is inside the weighing plate 9. The auxiliary rod 15 passes through the upper side wall of the weighing plate 9 and is connected to the output end of the limit motor 14. The contact rod 16 is on one side of the auxiliary rod 15 and fits against the weighing plate 9. A control panel 4 is provided on one side wall of the moving box 8. The control panel integrates a PLC control system. All the above devices are connected to the PLC control system.

[0027] During operation, the PLC control system on control panel 4 presets the weight grading range of salted duck eggs (e.g., light, medium, and heavy), and sets the sorting speed, conveyor belt 2 operating parameters, and feeding device operation mode. After starting the equipment, the PLC automatically initializes each component, and the rotating motor 11, limit motor 14, and feeding device enter standby mode. The feeding device grabs duck eggs from the raw material basket, flexibly clamps and smoothly transfers them to the weighing system 10 above the weighing plate 9, ensuring that the duck eggs are placed without collision. The weighing system 10 measures the weight of the duck eggs in real time. Its internal pressure sensor immediately senses the vertical pressure applied by the duck eggs and converts the pressure signal into an electrical signal. The electrical signal is converted into a digital signal by the internal analog-to-digital converter (ADC) and transmitted to the microprocessor in the control system. At the same time, the data is synchronously transmitted to the control panel 4 for display. The PLC determines the grade (light, medium, or heavy) of the duck eggs according to the preset range. When the control system analyzes the weight of the duck eggs... If the weight meets the intermediate weight zone, the PLC immediately sends a command to the limit motor 14. The limit motor 14 drives the auxiliary rod 15 to rotate, which in turn drives the contact rod 16 to rotate around its axis. The contact rod 16 rotates and contacts the surface of the duck egg, smoothly pushing it to the intermediate conveyor belt 2 and into the standard grade collection area. If the weight is less than or greater than the range, the PLC starts the rotating motor 11. The output shaft of the rotating motor 11 drives the rotating rod 12 to rotate. Since the translation block 13 is threadedly connected to the rotating rod 12, the rotation of the rotating rod 12 is converted into the linear displacement of the translation block 13, which drives the weighing plate 9 to move horizontally to directly above the corresponding light or heavy conveyor belt 2. Then the limit motor 14 starts, and the contact rod 16 rotates according to the above operation to push the duck egg to the target conveyor belt 2 and into the light or heavy collection area. After completing a single sorting, the weighing plate 9 returns to its initial position, and the feeding device cyclically grabs the next duck egg. The conveyor belt 2 continues to operate, transporting the sorted duck eggs to the corresponding area, realizing fully automatic continuous operation.

[0028] In practical use, duck eggs need to be grasped flexibly and accurately to avoid collision damage caused by manual placement. To meet the above requirements, in this embodiment, the feeding device includes a robotic arm 6 and a gripping claw 7. The robotic arm 6 is located on the upper end of the connecting plate 5, and the gripping claw 7 is located at one end of the robotic arm 6. The PLC transmits the preset motion route to the robotic arm 6. The robotic arm 6 generates the optimal motion trajectory according to the coordinates, quickly moves to directly above the target duck egg, and descends vertically to the preset grasping height. At this time, the gripping claw 7 opens and flexibly grips (the gripping force is controlled by the PLC) the duck egg. Then, the robotic arm 6 is raised at a constant speed along the planned path and moves horizontally to above the weighing plate 9. The posture is finely adjusted to align the center of the duck egg with the center of the weighing plate 9. Finally, the gripping claw 7 opens at a constant speed until it completely detaches from the duck egg, ensuring vertical and gentle placement.

[0029] In actual use, it is necessary to improve the stability of the equipment. In order to meet the above requirements, in this embodiment, both the moving box 8 and the bottom wall of the conveyor plate 1 are provided with multiple sets of support rods 3.

[0030] In actual use, it is necessary to prevent duck eggs from sliding and shifting in order to improve positioning accuracy. In order to meet the above requirements, in this embodiment, the surface of the conveyor belt 2 is provided with anti-slip silicone texture.
