Grains and their products are prone to mold during production, processing, storage and transportation, leading to contamination by mycotoxins. Therefore, for grains and their oil products, mycotoxin detection is a common method to assess their safety level. With the improvement of food safety awareness, the detection of grains and their products has also extended to pesticide residues, heavy metal residues, etc. In addition, oil products in grain products also need to detect acid value, peroxide value, etc.

[0044] Figure 1 The perspective view of the automatic processing device provided by the embodiment of the present application.

[0045] Please refer to Figure 1 The automatic processing device 100 of the embodiment of the present application comprises a grinding module 10, a carrying module 20, a cap screwing module 30, a weighing and liquid adding module 40, a vortex module 50 and a centrifugal module 60.

[0046] The grinding module 10 is used for grinding the sample to be detected and pouring the ground sample to be detected (i.e. forming a powder material) into the opened sample tube.

[0047] The carrying module 20 is used for transferring the sample tube between the cap screwing module 30, the weighing and liquid adding module 40, the vortex module 50 and the centrifugal module 60. That is, the carrying module 20 is used for transferring the sample tube between the cap screwing station, the weighing and liquid adding station, the vortex station and the centrifugal station.

[0048] The cap screwing module 30 is used for opening or tightening the sample cover on the sample tube, and the opened sample tube is used for loading the sample to be detected. The weighing and liquid adding module 40 is used for weighing the opened sample tube and the sample to be detected in it and adding the extraction liquid matching the weight of the sample to be detected in the sample tube.

[0049] It can be understood that after the empty sample tube is placed at the cap screwing station by the carrying module 20, the cap screwing module 30 can unscrew the sample cap on the sample tube, at this time, the sample tube can be directly poured into the sample to be detected through other modules, or the sample tube can be transferred to the receiving station by the carrying module 20 to receive the sample to be detected. The application does not make specific limitations.

[0050] After the sample tube receives the sample to be detected, the weighing and liquid adding module 40 is used for weighing and liquid adding, and after the weighing and liquid adding module 40 adds the extraction liquid to the sample tube, the cap screwing module 30 can screw the sample cap on the sample tube, and then is transferred to the vortex station through the carrying module 20.

[0051] The vortex module 50 is used for vortex processing of the sample tube screwed by the cap screwing module 30, so as to mix the sample to be detected and the extraction liquid in the sample tube. The extraction liquid can be determined based on the target extract, and different target extracts can use different extraction liquids. After the vortex processing of the vortex module 50, the sample to be detected and the extraction liquid can be fully mixed, so as to fully extract the target extract in the sample to be detected.

[0052] The centrifugal module 60 is used for centrifugal processing of the sample tube after the vortex processing, so as to obtain the sample to be detected by centrifugal separation. The separated sample to be detected can be detected by the detection device 200, and finally the detection result of the sample to be detected is obtained.

[0053] In the automatic detection system of the application, based on the cooperation between the grinding module 10, the carrying module 20, the cap screwing module 30, the weighing and liquid adding module 40, the vortex module 50 and the centrifugal module 60 of the automatic processing device 100, the sample to be detected can be realized from grinding, weighing, liquid adding, cap closing extraction and separation (also called sample pretreatment process), so as to automatically and quickly obtain the target extract of the sample to be detected. This way of obtaining the sample to be detected in the whole process of automation not only greatly saves manpower, improves the sample pretreatment efficiency and the subsequent detection efficiency, but also avoids the influence of subjective misoperation and manual intervention on the detection accuracy. Therefore, the processing efficiency and the processing accuracy of the automatic processing device 100 based on the application are high, and it can perform various quality evaluations in the production, processing, storage and flow process of the sample to be detected (especially the grain and its products).

[0054] Please continue to refer to Figure 1 The automatic processing device 100 of the embodiment of the application further comprises a sample rack 70, and the sample rack 70 is provided with a plurality of sample slots, each sample slot being used for placing a corresponding sample tube.

[0055] Please continue to refer to Figure 1The automatic processing device 100 provided in the embodiments of the present application can further comprise a drying module 80, which is used to dry the sample to be detected before the sample to be detected enters the grinding module 10, so as to avoid the influence of moisture in the sample to be detected on the detection result.

[0056] Please continue to refer to Figure 1 The automatic processing device 100 provided in the embodiments of the present application further comprises a first mounting bracket 90, wherein the grinding module 10, the conveying module 20, the cap screwing module 30, the weighing and liquid adding module 40, the vortex module 50, the centrifugal module 60, the sample rack 70 and the drying module 80 are all mounted on the first mounting bracket 90.

[0058] Figure 2 An internal structure schematic view of the centrifugal module provided in the embodiments of the present application.

[0059] Please refer to Figure 2 The centrifugal module 60 in the embodiments of the present application comprises a centrifugal mounting seat 61, a centrifugal driving unit 62 and a pushing unit 64.

[0060] The centrifugal mounting seat 61 is provided with a plurality of centrifugal grooves 611, and the sample tube A to be centrifuged is placed in a corresponding centrifugal groove 611. The centrifugal driving unit 62 is connected with the centrifugal mounting seat 61, and is used to drive the centrifugal mounting seat 61 to rotate, so as to realize the centrifugal processing of the sample to be detected in the sample tube A.

[0061] The pushing unit 64 is used to drive the centrifugal mounting seat 61 to rotate. The pushing unit 64 can drive the centrifugal mounting seat 61 to rotate and rotate to a preset position in the corresponding centrifugal groove 611 before centrifugation, so that the sample tube A can be placed in the corresponding centrifugal groove 611. After centrifugal processing, the centrifugal mounting seat 61 will continue to rotate due to inertia. At this time, the centrifugal mounting seat 61 can be decelerated by the pushing unit 64, until the sample tube A after centrifugal processing is rotated to the preset position and is taken out.

[0062] In this embodiment, the centrifugal driving unit 62 is used to ensure the centrifugal effect of the mixture of the sample to be detected and the extraction liquid in the sample tube A, so as to achieve solid-liquid separation, and the liquid in the upper layer is the liquid to be detected. The pushing unit 64 can ensure that the sample tube A can be placed at a specific position before centrifugation, and after centrifugation, the centrifugal mounting seat 61 can be slowed down and the sample tube A to be detected in the centrifugal mounting seat 61 can be rotated to a preset position and taken out, so as to realize the taking and placing of the sample tube A at a specific position in the centrifugal mounting seat 61, thereby helping to improve the processing efficiency of the automatic processing device 100.

[0063] Further, the centrifugal module 60 in the embodiment of the present application further comprises an induction unit (not shown), which is arranged on the centrifugal mounting seat 61 (such as the bottom of the centrifugal mounting seat 61), and is used to induce whether the centrifugal mounting seat 61 is rotated to a preset position and / or whether the sample tube A exists in the centrifugal groove 611 corresponding to the preset position. The specific arrangement position of the induction unit can be determined according to the preset position.

[0064] Please continue to refer to Figure 2 The pushing unit 64 comprises a roller 641, a rotating mechanism 642 and a pushing mechanism 643. The rotating mechanism 642 is connected with the roller 641, and the pushing mechanism 643 is connected with the rotating mechanism 642. The pushing mechanism 643 is used to drive the roller 641 to approach or move away from the centrifugal mounting seat 61 along the transverse direction W, and the rotating mechanism 642 is used to drive the roller 641 to rotate, so that the sample tube A can be placed in the corresponding centrifugal groove 611 and / or the sample tube A after centrifugal processing can be rotated to the preset position and taken out.

[0065] Specifically, before centrifugal processing, the roller 641 is brought into contact with the centrifugal mounting seat 61 by the pushing mechanism 643, and then the rotating mechanism 642 drives the roller 641 to rotate, so that the corresponding centrifugal groove 611 in the centrifugal mounting seat 61 is slowly rotated to a tube receiving position, so that the sample tube A to be centrifugally processed can be received in the centrifugal groove 611. After centrifugal processing, the roller 641 is brought into contact with the centrifugal mounting seat 61 by the pushing mechanism 643, and then the rotating mechanism 642 drives the roller 641 to rotate, so that the sample tube A to be detected in the centrifugal mounting seat 61 is slowly rotated to a preset position, thereby triggering the induction unit and stopping the action of the terminal roller 641, so that the sample tube A to be detected can be taken out at the preset position (i.e. the tube outlet position).

[0066] Please continue to refer to Figure 2 The centrifugal module 60 further comprises a cover plate 66 and a push-pull mechanism 63, the push-pull mechanism 63 is connected with the cover plate 66 and is used to drive the cover plate 66 to reciprocate along the transverse direction W, so that the cover plate 66 can be arranged on the plurality of centrifugal grooves 611 or opened.

[0067] Based on the arrangement of the cover plate 66 and the push-pull mechanism 63, the plurality of centrifugal grooves 611 can be closed by the cover plate 66 in the centrifugal process, so as to restrict the to-be-detected target sample tube A in the corresponding centrifugal groove 611, thereby preventing accidents caused by objects entering the centrifugal groove 611 or the sample tube A in the centrifugal groove 611 being thrown out due to imbalance in the centrifugal process; and the centrifugal groove 611 can be opened before the centrifugal process, so as to place the sample tube A in the corresponding centrifugal groove 611.

[0068] Figure 3 A structural schematic diagram of a balancing unit of a centrifugal module provided in the embodiment of the present application.

[0069] Referring to Figure 3 The centrifugal module 60 in the embodiment of the present application further includes a balancing unit 65, which can be arranged near the centrifugal mounting base 61 and includes a balancing rack 651 and a plurality of balancing tubes (not shown) of different weights arranged on the balancing rack 651.

[0070] Specifically, the balancing rack 651 is provided with a plurality of balancing grooves 6511 for placing the balancing tubes, and in order to accurately determine whether the balancing tube exists in each balancing groove 6511, a detection sensor 652 can be arranged in each balancing groove 6511.

[0071] When the weighing and liquid adding module 40 obtains the weight of the sample tube A and the to-be-detected sample in the sample tube A, the balancing tube with the smallest difference can be selected, and the balancing tube can be placed in the centrifugal groove 611 symmetrical to the sample tube A by the carrying module 20, so that the centrifugal mounting base 61 can be kept balanced in the centrifugal process. Moreover, based on the arrangement of the detection sensor 652, the carrying module 20 can accurately take the balancing tube in the corresponding balancing groove 6511, thereby avoiding the imbalance caused by taking empty or taking wrong.

[0072] Figure 4 A first cover body of a centrifugal module provided in the embodiment of the present application and a positional relationship between the centrifugal mounting base and the roller are shown in a schematic diagram.

[0073] Referring to Figure 4 The centrifugal module 60 in the embodiment of the present application further includes a first cover body 67, and the centrifugal mounting base 61 is movably arranged in the first cover body 67. The first cover body 67 is provided with a limiting opening 671 communicating with the inside of the first cover body 67, and the limiting opening 671 faces the roller 641 in the transverse direction W, so as to accommodate the roller 641.

[0074] In this embodiment, the centrifugal mounting seat 61 and the pushing unit 64 are isolated by the first cover body 67, so that the centrifugal imbalance can avoid affecting the pushing unit 64 by throwing the sample tube A inside. In addition, the position of the roller 641 can be positioned by the limiting opening 671 on the first cover body 67, so that the roller 641 can be in contact with the centrifugal mounting seat 61 appropriately, thereby ensuring that the centrifugal mounting seat 61 can still run smoothly after being in contact with the roller 641.

[0075] Figure 5 A structural schematic diagram of a support assembly provided in the embodiment of the application is shown.

[0076] Please refer to Figure 5 The centrifugal module 60 further includes a support assembly 68, which includes a support piece 681 and a damping piece 682. The support piece 681 is used to support the centrifugal mounting seat 61 in the first cover body 67, and the damping piece 682 is arranged at the bottom of the support piece 681.

[0077] In this embodiment, the centrifugal mounting seat 61 is supported by the additional support assembly 68, which can avoid the influence on the centrifugal driving unit 62 by directly supporting the centrifugal mounting seat 61 on the housing of the centrifugal driving unit 62. In addition, based on the arrangement of the damping piece 682, the vibration generated by the centrifugal mounting seat 61 during the centrifugal process can be timely absorbed by the damping piece 682.

[0078] Please continue to refer to Figure 5 The support piece 681 includes a support body 6811 and a plurality of support leg portions 6812. The centrifugal mounting seat 61 is placed on the support body 6811, and the plurality of support leg portions 6812 are arranged at intervals along the circumference of the support body 6811. The bottom of each support leg portion 6812 is provided with a corresponding damping piece 682. The plurality of damping pieces 682 are used for damping at multiple positions, which further improves the stability during the centrifugal process.

[0079] Figure 6 An external structural schematic diagram of the centrifugal module provided in the embodiment of the application is shown.

[0080] Please refer to Figure 6 The centrifugal module 60 in the embodiment of the application further includes a bottom plate 691 and an outer cover 692. The outer cover 692 is connected with the bottom plate 691 and forms a mounting chamber. The centrifugal driving unit 62 and the pushing unit 64 are mounted on the bottom plate 691 in the mounting chamber. The outer cover 692 is provided with a taking and placing opening 6921 on the side facing the centrifugal groove 611 in the upward and downward direction H. The taking and placing opening 6921 is used to place and take out the sample tube A.

[0081] Based on the setting of the cover 692 and the setting and taking opening 6921 of the cover 692, the safety in the centrifugal process is increased. Specifically, before the centrifugal treatment, after the roller 641 is in contact with the centrifugal mounting seat 61 by the pushing mechanism 643, the roller 641 is rotated by the rotating mechanism 642, so that the corresponding centrifugal groove 611 in the centrifugal mounting seat 61 is slowly rotated to the position of the setting and taking opening 6921, so that the centrifugal groove 611 can receive the sample tube A to be centrifuged placed by the carrying module 20. After the centrifugal treatment, after the roller 641 is in contact with the centrifugal mounting seat 61 by the pushing mechanism 643, the roller 641 is rotated by the rotating mechanism 642, so that the sample tube A to be detected in the centrifugal mounting seat 61 is slowly rotated to the position of the setting and taking opening 6921, so that the carrying module 20 can be used to take out the sample tube A to be detected through the setting and taking opening 6921.

[0082] It can be understood that the up-down direction H, the lateral direction W and the longitudinal direction L of the automatic processing device 100 in the application are three coordinate axis directions perpendicular to each other, wherein the up-down direction H is the depth direction of the centrifugal groove 611, the lateral direction W is the movement direction of the pushing mechanism 643 driving the roller 641, and the longitudinal direction L is the direction perpendicular to the up-down direction H and the lateral direction W.

[0083] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model. Those skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.
