Description

Technical Field

[0001] The utility model relates to the field related to food detection, and more specifically to a food placing device for food detection. Background Art

[0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly some harmful and toxic indicators, such as heavy metals, aflatoxin, etc. An important aspect of food science and engineering is to introduce and apply chemical unit operations and develop food engineering unit operations, thereby promoting the development of the food industry towards large-scale, continuous and automated production.

[0003] The existing food testing placer clamps the container at the bottom to ensure the fixation. Although the bottom clamp can adapt to containers of different diameters, the placer is prone to tilt when it is bumped due to the clamping at one end. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a food placer for food testing. The device fixes the container by clamping it up and down to ensure that the container will not fall or tilt even if it is bumped. At the same time, it can adapt to containers of different heights and has a sealing function for open containers.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A food placing device for food testing comprises a placing box, the opening end of the placing box is threadedly connected with a sealing cover, and is characterized in that: a plurality of fixed sealing components are circumferentially mounted on the lower end surface of the sealing cover;

[0007] The fixed sealing assembly includes an externally threaded rod and an internally threaded rod, one end of the externally threaded rod is rotatably mounted in a groove provided on the lower end surface of the sealing cover, the other end of the externally threaded rod is fixedly mounted with an external sprocket, one end of the internally threaded rod is rotatably mounted in another groove provided on the lower end surface of the sealing cover, the other end of the internally threaded rod is fixedly mounted with an internal sprocket, the chain is mounted on the external sprocket and the internal sprocket, a turning knob is fixedly mounted on the lower end surface of the external sprocket, and the two ends of the support plate are respectively threadedly connected with the externally threaded rod and the internally threaded rod.

[0008] As a further optimization of the technical solution, the lower end surface of the sealing cover of the food placing device for food testing of the utility model is provided with a rubber layer.

[0009] As a further optimization of the technical solution, the upper end surface of the support plate of the food placement device for food testing of the utility model is provided with a rubber layer.

[0010] As a further optimization of the technical solution, a hemispherical groove is provided in the middle position of the upper end surface of the support plate of the food placement device for food testing of the utility model.

[0011] As a further optimization of the technical solution, the upper end surface of the sealing cover of the food placing device for food testing of the utility model is provided with a strip handle which is easy to rotate.

[0012] The beneficial effects of the food placing device for food testing of the utility model are as follows:

[0013] The sealing cover is opened through the bar handle, and the container to be placed is placed on the support plate. Then the outer sprocket is rotated through the knob. The outer sprocket drives the inner sprocket to rotate synchronously through the chain, so that the outer threaded rod and the inner threaded rod rotate synchronously, and then the support plate moves upward, so that the support plate and the sealing cover clamp the container to achieve the purpose of fixing. The lower end surface of the sealing cover is provided with a rubber layer, which can increase the friction with the container to ensure the stability of the container and seal the opened container. Multiple fixed sealing components are all independently operated, and containers of different heights can be placed at the same time. A hemispherical groove is provided in the middle position of the upper end surface of the support plate, which can place round-bottomed test tubes to increase stability.
