Abstract
Description
Technical Field
[0001] This utility model relates to food inspection equipment, and in particular to a food inspection weighing and fixing device, belonging to the technical field of food testing auxiliary tools. Background Technology
[0002] Food safety testing must be conducted according to relevant national standards to detect harmful substances in food, with toxic and harmful indicators such as heavy metals and aflatoxin being key targets. The weighing process is crucial in the inspection of grain and oil products. Since grains and oils are not packaged before production, they are usually poured into weighing dishes before weighing for testing. This process directly affects the accuracy of subsequent test results. However, shallow and flat weighing dishes can easily cause liquid to spill, thus affecting weighing accuracy.
[0003] Publication number CN223005607U discloses a food inspection weighing and fixing device, including an upper support cylinder and a lower support base. Four connecting screws are interlaced on the outer surface of the lower support base, arranged in a circular array. The upper support cylinder is detachably mounted on the upper end of the lower support base via the four connecting screws. Two positioning components are disposed within the upper support cylinder, arranged vertically. The design of the positioning components in this food weighing and fixing device ensures that the container is stably and vertically placed on the balance tray, avoiding the risk of sample spillage due to container tilting, and reducing shaking during the weighing process, thus improving the accuracy of the weighing results. Furthermore, the overall assembly is simple and quick, reducing operating steps and improving work efficiency. In addition, it can adapt to containers of different sizes and shapes, exhibiting strong versatility.
[0004] While this device effectively avoids the risk of sample spillage due to container tilting, its design, which uses four sets of electric telescopic rods to move the clamping plate towards the center to contact and wrap around the outer wall of the container for anti-slip fixation, offers high flexibility and helps improve the accuracy of weighing results. However, it has significant limitations in practical applications. On the one hand, the synchronous extension and retraction control of the four sets of telescopic rods requires extremely high precision. If the movements are not synchronized, the container is prone to tilting due to an imbalance in clamping force, which could even cause the sample to tip over. On the other hand, the initial purchase cost of the four sets of electric telescopic rods is relatively high, and the subsequent maintenance costs are also relatively high. Therefore, improvements are needed.
[0005] Therefore, a fixed device for weighing and inspecting food is proposed. Utility Model Content
[0006] In view of this, the present invention provides a food inspection and weighing fixing device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0008] In a further preferred embodiment, the lever is slidably disposed within the arc-shaped groove, and the protrusion is disposed within the guide groove.
[0009] More preferably, one end of the coil spring is installed on the inner wall of the placement cylinder, and the other end of the coil spring is installed below the rotating plate.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0027] like Figure 1-5 As shown, this utility model embodiment provides a food inspection weighing and fixing device, including a weighing platform 1, a placement cylinder 2 connected to the weighing platform 1, a perforated guide groove 3 provided in the placement cylinder 2, a bearing 4 provided in the placement cylinder 2, a rotating plate 5 rotatably mounted in the placement cylinder 2 via the bearing 4, a guide groove 6 provided in the rotating plate 5, an arc-shaped groove 7 provided in the placement cylinder 2, a coil spring 9 provided in the placement cylinder 2, a fixing plate 10 installed in the placement cylinder 2, the bearing 4 and the rotating plate 5 are both located below the fixing plate 10, a limit groove 11 provided in the fixing plate 10, a guide rod 12 slidably disposed in the perforated guide groove 3, an mounting plate 13 installed at one end of the guide rod 12, a slider 14 installed below the mounting plate 13, a protrusion 15 installed below the slider 14, a lever 8 installed below the rotating plate 5, and a buffer plate 16 connected to the mounting plate 13 via a quick-release structure.
[0028] In one embodiment, the lever 8 is slidably disposed within the arc-shaped groove 7, and the protrusion 15 is disposed within the guide groove 6. The sliding of the lever 8 within the arc-shaped groove 7 can limit the rotation range of the rotating plate 5, preventing excessive rotation that could damage the components; the protrusion 15 is disposed within the guide groove 6 to ensure that the rotating plate 5 can accurately drive the mounting plate 13 to open and close through the guide groove 6 when it rotates.
[0029] In one embodiment, one end of the coil spring 9 is installed on the inner wall of the placement cylinder 2, and the other end of the coil spring 9 is installed below the rotating plate 5. The two ends of the coil spring 9 are connected to the placement cylinder 2 and the rotating plate 5 respectively. When the rotating plate 5 rotates, the coil spring 9 generates elastic deformation and stores potential energy. After the lever 8 is released, it can drive the rotating plate 5 to automatically reset, thereby driving the mounting plate 13 to complete the clamping of the grain and oil product container.
[0030] In one embodiment, the slider 14 is adapted to the limiting groove 11, and the slider 14 is slidably disposed within the limiting groove 11. The slider 14 is adapted to and slidably connected to the limiting groove 11, which restricts the movement direction of the mounting plate 13, ensuring that the mounting plate 13 can only open and close smoothly in the radial direction, avoiding offset or shaking.
[0031] In one embodiment, the quick-release structure includes a slot 17, an insert plate 18, a pin 19, a limiting plate 20, and a torsion spring 21. The slot 17 is disposed within the mounting plate 13, the insert plate 18 is mounted on the buffer plate 16, the pin 19 is mounted on the back of the mounting plate 13, the limiting plate 20 is rotatably mounted on the pin 19, and the torsion spring 21 is sleeved on the pin 19. The quick-release structure enables rapid assembly and disassembly of the buffer plate 16 and the mounting plate 13. Under the action of the torsion spring 21, the limiting plate 20 can automatically abut against the insert plate 18 to ensure a stable connection.
[0032] In one embodiment, the slot 17 is adapted to the insert plate 18, and both the slot 17 and the insert plate 18 are T-shaped. The adaptation design of the T-shaped slot 17 and the T-shaped insert plate 18 allows the insert plate 18 to be positioned axially after being inserted into the slot 17, while preventing it from falling out in the vertical direction.
[0033] In one embodiment, one end of the torsion spring 21 is mounted on the pin 19, and the other end of the torsion spring 21 is mounted below the limiting plate 20. The torsion spring 21 drives the limiting plate 20 to tend to abut against the slot 17. The torsion spring 21 releases potential energy to cause the limiting plate 20 to rotate in the opposite direction, so that it abuts against the slot 17.
[0034] In operation, when weighing grain and oil products, the operator first moves the lever 8. The lever 8 slides along the arc-shaped groove 7 inside the placement cylinder 2, causing the rotating plate 5 to rotate around the bearing 4. At this time, the coil spring 9 connected below the rotating plate 5 is twisted and stores elastic potential energy. During the rotation of the rotating plate 5, the guide groove 6 inside it slides relative to the protrusion 15 below the slider 14. Under the pushing force of the guide groove 6, the slider 14 slides outward along the limiting groove 11 inside the fixed plate 10, thereby causing the mounting plate 13 connected to the slider 14 to open synchronously towards the inner wall of the placement cylinder 2, forming a space that can accommodate the container to be measured. After placing the grain and oil container inside, release the lever 8. The coil spring 9 releases its elastic potential energy and drives the rotating plate 5 to rotate in the opposite direction. The guide groove 6 and the protrusion 15 cooperate again, pushing the slider 14 to slide inward along the limiting groove 11. This causes multiple sets of mounting plates 13 to converge towards the center simultaneously. The buffer plate 16 on the mounting plate 13 fits tightly against the outer wall of the container, forming a wrapping limit on the container. This effectively prevents the container from becoming unstable during the weighing process and stabilizes the item to be weighed. After the container to be weighed stabilizes, the weighing reading can be taken.
[0035] When the buffer plate 16 becomes aged, damaged, or needs replacement or maintenance, the operator moves the limiting plate 20. The limiting plate 20 rotates around the pin 19. At this time, the torsion spring 21 sleeved on the pin 19 is compressed and stores elastic potential energy, and the limiting plate 20 disengages from the tight-fitting limiting state against the insert plate 18. Since the insert plate 18 and the slot 17 in the mounting plate 13 are both T-shaped and mutually compatible, the insert plate 18 along with the buffer plate 16 can be directly pulled out from the slot 17 to complete the disassembly. When installing a new buffer plate 16, the insert plate 18 on the buffer plate 16 is aligned with the slot 17 and inserted. The limiting plate 20 is released, and the torsion spring 21 releases its potential energy, causing the limiting plate 20 to rotate in the opposite direction, so that it rests against the slot 17 again, forming a stable limiting position on the insert plate 18, ensuring that the buffer plate 16 is firmly installed and guaranteeing its buffering protection effect on the container during clamping.
[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
