Technical Field

[0001] The present invention relates to the technical field of food additive detection, and particularly discloses a multifunctional detection device for food chemical additives. Background Art

[0002] Food additives refer to artificial or natural substances added to food to improve the variety, color, aroma, and taste of food, as well as for preservation and processing technology needs. Food additive detection is to ensure that the additives in food comply with national or regional regulatory standards to protect the health and safety of consumers. The general steps for food additive detection are to dissolve the food in a base solution to obtain a test solution, then add different detection reagents in sequence, and finally put the test reagent into a chromatograph to obtain the additive content.

[0003] The applicant found that the existing detection devices on the market only have a single function of adding liquid test solutions and do not have a fast addition function for powdery / granular reagents, such as powdery color developers and indicators, and granular precipitants. Therefore, there is an urgent need for a multifunctional detection device for food chemical additives. Summary of the Invention

[0004] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the present invention is to provide a multifunctional detection device for food chemical additives.

[0005] To achieve the above purpose, a multifunctional detection device for food chemical additives of the present invention includes a box body. A storage module and a sample tube from the outside for adding a test reagent to be added are arranged inside the box body. The storage module includes a test reagent tube for installing an external test reagent. It further includes a conversion module and a first driving member for driving the conversion module to approach or move away from the test reagent tube. A first material taking component and a second material taking component are arranged on the conversion module. The conversion module includes a fourth driving member, and the fourth driving member is used for the first material taking component / the second material taking component to approach the test reagent tube and the sample tube. The first driving member is used for driving the conversion module to approach or move away from the test reagent tube and the sample tube.

[0006] Preferably, the conversion module includes a first frame and a second frame rotatably disposed on the first frame. A fourth driving member is disposed on the first frame for rotating the second frame relative to the first frame. The first material taking assembly and the second material taking assembly are fixedly disposed relative to the second frame. By designing the first frame and the second frame rotatably disposed on the first frame, and cooperating with the fourth driving member disposed on the first frame to drive the second frame to rotate relative to the first frame, it has the function of flexibly adjusting the operation range, achieving the effect of efficiently picking and placing materials at different positions or angles. In this embodiment, it mainly reflects the replacement of different material taking assemblies. At the same time, the first material taking assembly and the second material taking assembly are fixedly disposed relative to the second frame, ensuring the stability and accuracy of the material taking process, and further improving the efficiency and precision of material conversion.

[0007] Preferably, a rod body is disposed on the second frame, and a first plate body is disposed at the free end of the rod body. The end of the material taking assembly is provided with a second plate body for cooperating with the first plate body. The material taking assembly is disposed on the first plate body via the second plate body. By disposing the rod body on the second frame and configuring the first plate body at the free end of the rod body, and at the same time designing the end of the material taking assembly with a second plate body that cooperates with the first plate body, the material taking assembly can be stably disposed on the first plate body through the second plate body. This technical means has the functions of enhancing structural stability and facilitating the installation and disassembly of the material taking assembly, achieving the effects of improving the convenience of equipment maintenance and ensuring the stable progress of the material taking operation. It not only simplifies the replacement process of the material taking assembly but also ensures that under different operation requirements, the material taking assembly can be quickly and accurately positioned and fixed at the predetermined position, improving the overall operation efficiency and flexibility.

[0008] Preferably, a fifth driving member is further disposed on the second frame. The output end of the fifth driving member is connected to the end of the rod body away from the material taking assembly. The fifth driving member is used to rotate the material taking assembly disposed on the rod body relative to the second frame. By disposing the fifth driving member on the second frame and connecting the output end of the fifth driving member to the end of the rod body away from the material taking assembly, the material taking assembly disposed on the rod body can be rotatably disposed relative to the second frame, having the function of flexibly adjusting the angle and position of the material taking assembly, achieving the effect of precisely and efficiently picking and placing materials in a complex operation environment.

[0009] Preferably, the first material taking assembly includes a column body. Second plate bodies and a material taking member are respectively disposed at both ends of the column body. The material taking member is arranged in an inverted frustum shape, which is convenient for picking and placing external powdery / granular materials. By designing the column body and respectively disposing the second plate bodies and the material taking member arranged in an inverted frustum shape at both ends thereof, this technical means has the functions of enhancing the stability of material taking and improving the efficiency of material picking and placing, achieving the effect of stably carrying and efficiently transporting materials during the material taking process. The column body, as a connecting structure, ensures the stable connection between the second plate body and the material taking member.

[0010] Preferably, the number of material taking members is at least two, and the two material taking members are stacked. The size of the material taking member at the end far from the column is not larger than that of the material taking member at the end close to the column. A protruding portion is formed between the material taking member and the adjacent material taking member / column. The protruding portion is used to carry external materials, and has the functions of adaptively grasping a large amount of materials and increasing the load-bearing stability. The multi-stage stacked material taking members and the protruding portions therebetween provide multi-point support for the materials, and the amount of materials to be picked and placed can be determined according to the depth dimension of the material taking member.

[0011] Preferably, the second material taking assembly includes a conical member. A second plate body is arranged on the conical member. An extension member is arranged on the conical member and extends by bending from the end of the conical member. The extension member is arranged in a disc shape for accommodating external materials, and has the functions of expanding the material accommodating range and enhancing the material grasping stability, achieving the effect of effectively accommodating various liquid materials. The design of the conical member enables the second material taking assembly to flexibly adapt to the material accommodating range and provides a wider support surface for the materials. At the same time, the close combination of the extension member and the conical member enhances the stability of the materials during the grasping process and reduces the possibility of the materials slipping or tilting.

[0012] Preferably, an arc transition is formed between the bottom end of the conical member and the extension member. An inner ring and a top ring are also arranged on the conical member. The inclination angle of the inner ring relative to the horizontal plane is not less than the inclination angle of the extension member relative to the horizontal plane, and the inclination angle of the top ring relative to the horizontal plane is not greater than the inclination angle of the extension member relative to the horizontal plane. The design of the arc transition helps the smooth transition of the materials between the conical member and the extension member, reduces the jamming or accumulation of the materials during the transfer process, and improves the smoothness of the material flow. At the same time, the larger inclination angle of the inner ring can guide the materials to gather towards the center, which is beneficial to the centralized treatment and grasping of the materials; while the smaller inclination angle of the top ring provides a stable support surface, enhances the overall stability of the structure, and prevents the materials from falling off due to shaking during the grasping or handling process. This design not only improves the material handling capacity of the second material taking assembly but also ensures the safety and reliability of the materials during the grasping process.

[0013] Preferably, a first magnetic member is arranged on the first plate body, and a second magnetic member for cooperating with the first magnetic member is arranged on the second plate body.

[0015] The beneficial effects of the present invention are as follows: by driving the conversion module by the first driving member to be close to or away from the detection agent tube, the relative positions of the first material picking component and the second material picking component and the detection agent tube can be flexibly adjusted, which is convenient for automatic taking of medicines, improves the degree of automation of the detection process, reduces the tediousness of manual operation, and improves work efficiency. At the same time, the function of the fourth driving member is to drive the first material picking component or the second material picking component to be close to the detection agent tube and the sample tube, thereby realizing the precise taking and placing of medicines and samples by different material picking components, ensuring the accuracy and reliability of the detection, not only optimizing the operating process of the equipment, but also enhancing the versatility of the equipment, so that the equipment can be suitable for the detection needs of various food chemical additives, and improving the practicality and application value of the equipment.
