Description

Technical Field

[0001] This utility model relates to the field of food safety testing technology, specifically to an automatic discharging device. Background Technology

[0002] With the accelerating pace of globalization and the increasing diversification of consumer demands, the complexity of the food supply chain is constantly rising, making food safety issues increasingly intricate and a global challenge. Food safety is not only closely related to everyone's life and health, but also the cornerstone of social stability and economic development. Ensuring food safety and preventing all potential risks has become a major issue of widespread concern across all sectors of society.

[0003] Food testing, as the first line of defense in safeguarding food safety, is becoming increasingly important. Traditional food testing methods often prove inadequate when faced with massive volumes of samples. The testing process involves treating each batch of samples with a specific soaking solution, accompanied by a series of tedious manual operations. Testing personnel must manually pick up and repeatedly stir the soaking solution with stirring rods to ensure the sample and solution are fully mixed; subsequently, they must manually pick up and extract the soaking solution with pipettes, and precisely add various reagents to prepare the test sample for subsequent analysis.

[0004] This process is not only time-consuming and labor-intensive, but also fraught with risks. On the one hand, faced with a large volume of samples, testing personnel must frequently select the necessary tools one by one from piles of materials, which not only significantly slows down testing efficiency but also increases uncertainties in the operation. On the other hand, whether it's stirring rods, pipettes, or other testing instruments, repeated handling and operation can introduce secondary contamination due to operational errors or improper cleaning, thus seriously affecting the accuracy of the test results. Such contamination may not only lead to misjudgments or omissions of food safety issues but may also mask true food safety risks, posing a threat to consumers' health. Summary of the Invention

[0023] Compared with the prior art, the automatic discharging device of this utility model has the following advantages:

[0024] (1) The automatic discharging device of this utility model includes at least a fixed plate, a movable plate, and a first driving mechanism. The fixed plate is provided with a slot and a discharging channel located below the slot. The movable plate is slidably connected to the fixed plate. The movable plate is provided with a first working part and a second working part extending towards the fixed plate. The second working part is provided with a discharging port adapted to the side of the discharging channel away from the slot. The first working part has a first state in which it extends into the slot and the discharging channel to isolate the slot and the discharging channel, and a second state in which it exits the slot and the discharging channel to connect the slot and the discharging channel.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0044] An automatic discharging device according to this embodiment, such as Figure 1 As shown, it includes at least a fixed plate 1, a movable plate 2, and a first drive mechanism 3. Figure 2 and Figure 3 As shown, the fixed plate has a slot 11 and a discharge channel 12 located below the slot. The movable plate is slidably connected to the fixed plate, as shown. Figure 4 As shown, the movable plate is provided with a first working part 21 and a second working part 22 extending towards the fixed plate. The second working part is provided with a discharge port 221 that is adapted to the side of the discharge channel 12 away from the slot 11.

[0045] The first working part 21 has a first state in which it extends between the slot 11 and the discharge channel 12, isolating the slot from the discharge channel, and a second state in which it exits the slot from the discharge channel, connecting the slot to the discharge channel. The second working part 22 has a third state in which the discharge port is misaligned with the discharge channel, closing the discharge channel, and a fourth state in which the discharge port is connected to the discharge channel, opening the discharge channel. The output end of the first drive mechanism 3 is fixedly connected to the moving plate 2. This design allows the discharge process to be automated without manual intervention, greatly improving work efficiency and accuracy.

[0046] The first drive mechanism drives the movable plate to slide relative to the fixed plate, causing the first working part to switch from a first state to a second state, while the second working part switches from a fourth state to a third state; and vice versa. On one hand, the first and second working parts on the movable plate work together to achieve the isolation and connection between the slot and the discharge channel, as well as the closure and opening of the discharge channel. This dual-working-part design makes the discharge device more functional and can meet different discharge requirements. On the other hand, the structure is compact, requiring only one drive mechanism to achieve flexible switching between the first and second working parts, resulting in low manufacturing costs and ease of installation and maintenance.

[0047] In this embodiment, as Figure 2 and Figure 3 As shown, the fixed plate 1 has a first groove 13 between the slot 11 and the discharge channel 12. The first working part of the moving plate 2 is adapted to the first groove. The first driving mechanism 3 is used to drive the first working part of the moving plate to slide relative to the first groove, thereby allowing the first working part to switch between a first state and a second state. On the one hand, by providing a groove on the fixed plate, the moving plate can slide along the groove instead of occupying extra space for linear movement. This makes the overall structure more compact and improves space utilization. On the other hand, the moving plate can maintain a stable motion trajectory during sliding. This helps to ensure the accuracy and reliability of the moving plate switching between the first state and the second state.

[0048] In this embodiment, the fixed plate 1 has a second chute 14 arranged parallel to the first chute on the side of the discharge channel 12 away from the slot. The moving plate 2 has a second working part 22 adapted to the second chute on the side of the first working part 21 near the discharge channel. The first driving mechanism 3 is used to drive the first working part of the moving plate to slide relative to the first chute, while the second working part slides relative to the second chute, thereby allowing the second working part to switch between the fourth state and the third state. On the one hand, through the dual guidance of the first and second chutes, the moving plate achieves better stability and guidance during the sliding process, which helps to reduce the shaking and offset of the moving plate during the sliding process and ensures its precise switching between different states. On the other hand, the parallel arrangement of the first and second chutes allows the moving plate to maintain balance and stability during the sliding process. This design helps to extend the service life of the moving plate and reduce the failure rate caused by unstable sliding.

[0049] The first drive mechanism 3 includes a linear motor, a hydraulic cylinder, or a pneumatic cylinder. In this embodiment, the first drive mechanism uses a linear motor, with a slider in the linear motor serving as its output end. The slider is fixedly connected to the end of the moving plate furthest from the first and second working parts.

[0050] Preferred, such as Figure 2 As shown, the outer edge of the fixing plate 1 extends outward to form several mounting parts 15 for mounting with external equipment.

[0051] An automatic discharging device according to this embodiment, such as Figure 1 As shown, it also includes a turntable 4 located above the fixed plate 1, and a second drive mechanism 5. (As shown...) Figure 5 As shown, the turntable 4 is provided with several material boxes 41 at intervals along the circumference, which are adapted to the positions of the slots for loading materials. Loading materials through the material boxes effectively ensures the cleanliness of the materials, eliminates uncertainties in the testing process, and improves the accuracy of the testing. The turntable 4 is provided with openings 42 that correspond one-to-one with the material boxes to accommodate the materials passing through sequentially, allowing the materials to fall one by one, avoiding the accumulation of materials at the discharge port, and improving the testing efficiency.

[0052] Preferably, the inner cavity of the material box 41 is tapered radially along the turntable 4 to reduce material shaking and scattering during transfer, thereby ensuring the integrity and safety of the material during transportation or processing. The material box 41 has mounting grooves 411 on both side walls.

[0053] The output end of the second drive mechanism 5 is fixedly connected to the turntable 4, and is used to drive the turntable 4 to rotate relative to the fixed plate 1. In this embodiment, as shown... Figure 6 As shown, the second drive mechanism 5 includes a drive element 51 located below the fixed plate 1, and a flange 52 with one end connected to the output end of the drive element and the other end fixedly connected to the turntable; the fixed plate is provided with a relief groove 16 that matches the flange.

[0054] In this embodiment, as Figure 1 and Figure 5 As shown, the outer edge of the turntable 4 is provided with first positioning parts 43 corresponding to the material boxes 41 at intervals around its rotation center axis, and first positioning sensors 44 adapted to the first positioning parts. The material boxes are adapted to the materials. Through the coordinated action of the first positioning parts and the first positioning sensors, different sampling and testing materials can be loaded into the material boxes. By adjusting the rotation angle and speed of the turntable, as well as the correspondence between the material boxes and the slots, the dropping of different materials and the quantity of materials dropped can be achieved.

[0055] In this embodiment, as Figure 1As shown, the automatic discharge device also includes at least two second positioning sensors 6 arranged at intervals along the sliding direction of the moving plate 2. The moving plate 2 is provided with a second positioning part 23 adapted to the second positioning sensors to achieve precise discharge control. This can not only avoid material waste, but also ensure the accuracy and consistency of the discharge quantity.

[0056] In summary, the above description is only a preferred embodiment of the present utility model and is 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.
