Description

Technical Field

[0001] The present application relates to the technical field of food testing, and in particular to a food testing, metering and weighing device. Background Art

[0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly the detection of some harmful and toxic indicators, such as heavy metals, aflatoxins, etc. During the food testing process, it is necessary to first accurately weigh the weight of the food being tested, which requires the use of a measuring weighing device.

[0003] Patent announcement number CN220542232U proposes a food inspection, metering and weighing device, which uses a weighing hopper with a trapezoidal cross-section to load and weigh the food to be weighed, and measures the volume of the weighed food while weighing. If the weight of the weighed food in the weighing hopper is overweight, the control plate is driven by the operating handle to move, and the food in the weighing hopper is discharged and reduced in weight, thereby solving the problems of existing flat-plate weighing, which is inconvenient in using powdered or granular food, and inconvenient in reducing the weight of the weighed food when the weight is higher than the required metering weight.

[0004] However, when food is unloaded and reduced in weight, the food falls through the feed tube onto the electronic weighing scale. Thus, the reduced weight of the food is still weighed, resulting in the total weighing weight remaining unchanged, thus affecting the food weight reduction and reducing the food weighing effect. Therefore, those skilled in the art have provided a food detection, metering and weighing device to solve the problems raised in the above background technology. Utility Model Content

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] The embodiment of the present application discloses a food detection, measurement and weighing device. Figure 1-5 A food detection and metering weighing device includes an electronic weighing scale body 1, the top of the electronic weighing scale body 1 is connected with a detection support frame 2, the top of the detection support frame 2 is fixed with a weighing hopper 3, the bottom end of the weighing hopper 3 is rotatably connected with a discharge plate 4, a discharge port 5 is opened in the middle of the bottom end of the weighing hopper 3, and a baffle 6 for blocking the discharge port 5 is fixed to the top of the discharge plate 4. A pull plate 7 is provided on one side of the weighing hopper 3 which can be lifted and lowered, and a lifting component 8 is provided on one side of the weighing hopper 3 to drive the pull plate 7 to move, and the pull plate 7 is connected to the discharge plate 4 through a sliding component 9.

[0030] In this embodiment, after the food is loaded into the weighing hopper 3, the food is weighed by the electronic weighing scale body 1. When it is necessary to reduce the material, the movement of the lifting component 8 drives the pull plate 7 to move downward, and the pull plate 7 drives the discharge plate 4 to rotate downward through the sliding component 9. The discharge plate 4 drives the baffle 6 to rotate downward, and the discharge port 5 is opened. The food that needs to be reduced in weight falls through the discharge port 5 onto the discharge plate 4, and then is discharged outward through the discharge plate 4, avoiding the food from falling onto the electronic weighing scale body 1 and affecting the weighing, thereby facilitating the reduction and weighing of the food and improving the weighing effect of the food.

[0031] It should be noted that this application is improved on the basis of patent number CN220542232U. The structures such as the electronic weighing scale 1, the detection support frame 2 and the weighing hopper 3 in this application have been disclosed in the above patent, so this application will not go into details.

[0032] In a further embodiment, Figure 3-4 As shown, the lifting assembly 8 includes a first slider 81 fixedly arranged at the top of the pull plate 7, a first slide groove 82 for the first slider 81 to slide is opened on one side of the weighing hopper 3, a screw rod 83 threadedly connected to the first slider 81 is rotatably connected in the first slide groove 82, and a driving motor 84 fixed to the screw rod 83 is fixed at the bottom end of the inner wall of the first slide groove 82, and the sliding assembly 9 includes a second slider 91 rotatably arranged at the bottom end of the pull plate 7, and a second slide groove 92 for the second slider 91 to slide is opened on one side of the blanking plate 4.

[0033] When the food needs to be reduced during the weighing process, the driving motor 84 drives the screw rod 83 to rotate, and the screw rod 83 drives the first slide 81 to move downward, and the first slide 81 drives the pull plate 7 to move downward, and the pull plate 7 drives the second slide 91 to slide in the second slide groove 92. Under the downward push of the pull plate 7, the unloading plate 4 can be driven to rotate downward. At the same time, the second slide 91 and the pull plate 7 cooperate with each other to facilitate the rotation of the unloading plate 4 during the rotation of the unloading plate 4. The second slide 91 adapts to the second slide groove 92 to facilitate the sliding of the second slide 91 in the second slide groove 92. During the rotation of the unloading plate 4, the baffle 6 can be driven to rotate, so that the baffle 6 is separated from the unloading port 5, and the food can fall onto the unloading plate 4 through the unloading port 5, and then be discharged outward through the unloading plate 4, avoiding the food falling onto the electronic weighing scale body 1 and affecting the weighing, thereby facilitating the unloading weighing of food and improving the weighing effect of food.

[0034] In a further preferred embodiment of the present invention, Figure 2 As shown, a slide bar 10 is provided in the weighing hopper 3 which can be raised and lowered. A vertical bar 11 is fixed at the bottom end of the slide bar 10. A plurality of dredging rods 12 are fixed obliquely on both sides of the vertical bar 11. A driving assembly 13 is provided in the weighing hopper 3 to drive the slide bar 10 to move.

[0035] When food is discharged into the weighing hopper 3, the movement of the driving component 13 drives the slide rod 10 to move up and down, and the slide rod 10 drives the vertical rod 11 to move up and down, and the vertical rod 11 drives the dredging rod 12 to move up and down to dredge the food, avoiding the impact of food blockage on the discharge, and improving the food discharge efficiency.

[0036] In a further embodiment, Figure 5 As shown, the driving assembly 13 includes a third slider 131 fixedly arranged at both ends of the slide rod 10, and a third slide groove 132 for the third slider 131 to slide is provided on both sides of the inner wall of the weighing hopper 3. The third slide groove 132 is fixedly connected to the third slider 131 through an electric telescopic rod 133, and sealing plates 14 are fixed on both sides of the third slider 131, which are respectively fixed to the two sides of the inner wall of the third slide groove 132.

[0037] When food is unloaded, the movement of the electric telescopic rod 133 drives the third slider 131 to move up and down, and the third slider 131 drives the slide rod 10 to move up and down, and the slide rod 10 drives the vertical rod 11 to move up and down, and the vertical rod 11 drives the dredging rod 12 to move up and down to dredge the food, thereby avoiding food accumulation and blockage that affects the unloading of food, thereby improving the unloading efficiency of food. The sealing plate 14 can be a telescopic plate or a rubber plate with the ability to shrink. In this way, when the third slider 131 moves up and down, the sealing plate 14 will not affect the normal movement of the third slider 131, and the third chute 132 can be sealed by the sealing plate 14 to avoid food falling into the third chute 132 and affecting the normal movement of the electric telescopic rod 133 and the third slider 131.

[0038] The implementation principle of a food detection and metering weighing device in the embodiment of the present application is as follows: after the food is loaded into the weighing hopper 3, the food is weighed by the electronic weighing scale 1. When the food needs to be reduced, the driving motor 84 drives the screw rod 83 to rotate, and the screw rod 83 drives the first slider 81 to move downward, and the first slider 81 drives the pull plate 7 to move downward, and the pull plate 7 drives the second slider 91 to slide in the second slide groove 92. Under the downward push of the pull plate 7, the discharge plate 4 can be driven to rotate downward. During the rotation of the discharge plate 4, the baffle 6 can be driven to rotate, so that the baffle 6 is separated from the discharge port 5, and the food The food can be dropped onto the discharge plate 4 through the discharge port 5 and then discharged outward through the discharge plate 4, thereby preventing the food from falling onto the electronic weighing scale body 1 and affecting the weighing, thereby facilitating the weight reduction and weighing of the food and improving the weighing effect of the food. When the food is weighed and discharged, the electric telescopic rod 133 moves, which drives the third slider 131 to move up and down, and the third slider 131 drives the slide bar 10 to move up and down, and the slide bar 10 drives the vertical rod 11 to move up and down, and the vertical rod 11 drives the dredging rod 12 to move up and down to dredge the food, thereby preventing food from accumulating and clogging and affecting the discharge, thereby improving the discharge efficiency of the food.
