[0048] Specifically,

[0049] The rotating unit comprises the rotating disc 7, the protective cover 5, a gear assembly and a damping assembly. The gear assembly is connected between the bottom surface of the rotating disc and the protective cover 5, and is used to drive the intermittent rotation of the rotating disc 7. The gear assembly comprises a first gear set and a second gear set.

[0050] The first gear set comprises a driven rotating shaft 17b and a full gear 12. The driven rotating shaft 17b is fixed to the rotating disc 7 after penetrating the full gear 12 and the protective cover 5 in sequence. The driven rotating shaft 17b is fixed to the full gear 12, and the other end of the driven rotating shaft 17b is rotatably connected to the protective cover 5. In addition, the shaft body of the driven rotating shaft 17b extends outward to form an extension edge 18 at the portion below the full gear. The second gear set comprises an incomplete gear 13 and a driving rotating shaft 17a. The incomplete gear 13 is engaged with the full gear 12. The driving rotating shaft 17a is fixed to the incomplete gear 13 at one end, and the other end of the driving rotating shaft 17a penetrates the protective cover 5 and is connected to a handle 19.

[0051] The handle 19 is rotated to drive the rotation of the incomplete gear 13, so that the full gear 12 can rotate intermittently, and then the driven rotating shaft 17b can rotate to drive the rotating disc 7 to rotate synchronously with the driven rotating shaft 17b.

[0052] The damping assembly comprises a spring 14 and a friction plate 15. The spring 14 is fixed between the bottom surface of the friction plate and the protective cover 5. The spring 14 is in a compressed state, and the top surface of the friction plate abuts against the extension edge 18. The spring 14 drives the friction plate 15 to abut against the extension edge 18 upwardly by the restoring force of the spring 14, so as to increase the interaction force between the friction plate 15 and the bottom surface of the extension edge 18, and the rotation of the full gear 12 requires a certain starting force.

[0053] The positioning unit comprises a positioning assembly and a thrust assembly. The positioning assembly is arranged on the top surface of the rotating disc in the circumferential direction of the rotating disc, and one of the positioning assemblies is located directly below the detection head 4. Each positioning assembly comprises a positioning block 10 and a limiting piece. The limiting piece penetrates the side wall of the positioning block.

[0054] The positioning block 10 is provided with a positioning groove in the direction from the top to the bottom, and is used for placing the slice. An installation groove is formed in the groove bottom of the positioning groove.

[0055] The limiting member is used for positioning and fixing the slice, and comprises spring rods 9 and limiting plates 11. The spring rods 9 are arranged on the two side walls of the positioning block respectively. The extending and retracting ends of the spring rods are penetrated through the side walls of the positioning block 10 and located in the positioning block. The limiting plates 11 are arranged on the extending and retracting ends of the spring rods. Each limiting plate 11 is provided with a sliding rod extending towards the bottom end of the limiting plate. The bottom of the positioning groove is provided with a sliding groove 101 matched with the sliding rod, so that each sliding rod is slidably connected to the corresponding sliding groove 101. The slice placed in the positioning groove is surrounded by the limiting plates 11 and the inner wall of the positioning groove. The slice is abutted against the limiting plates 11, the extending and retracting ends of the spring rods are compressed, and the restoring force is generated to press the slice, so that the edge of the slice is abutted against the inner wall of the positioning groove, thereby realizing the fixation of the slice in the positioning block.

[0056] Preferably, the above-mentioned positioning assembly is provided with eight positioning blocks, one of which is located directly below the detection head 4. One rotation of the incomplete gear 13 can drive the complete gear 12 to rotate by 1 / 8 of a circle, so that the turntable 7 can drive one positioning block 10 to move directly below the detection head 4 every time the intermittent movement is performed, thereby enabling all the positioning blocks 10 to be rotated by the turntable 7 to be in turn moved directly below the detection head 4 for detection.

[0057] The thrust assembly comprises a push plate 16 and a push rod 6. The push plate 16 is arranged in the installation groove, i.e., the size and shape of the push plate 16 are the same as those of the installation groove, so that the top surface of the push plate 16 located in the installation groove is flush with the bottom of the positioning groove. The push rod is fixed at the bottom end of the push plate and extends through the bottom of the positioning groove and the turntable 7. The push rod 6 is pushed upward to drive the push plate 16 to move upward, thereby facilitating the push plate 6 to be pushed out of the positioning groove. When the slice needs to be detected, the push plate 16 is located in the installation groove; when the detection of the slice is completed, the push plate 6 is pushed to move the slice out of the positioning groove, thereby facilitating the slice to be taken out.

[0058] The lifting unit comprises a threaded sleeve 31, a threaded rod 30, a rotating ring 8 and a guide rod 2. The threaded sleeve 31 is sleeved and threadedly connected to the outer wall of the threaded rod. The threaded sleeve 31 and the threaded rod 30 are arranged between the protective cover 5 and the base 1. The threaded sleeve 31 is fixed to the bottom end of the protective cover, and the threaded rod 30 is rotatably connected to the top end of the base. The rotating ring 8 is fixedly sleeved on the outer wall of the threaded rod 30 near the bottom end of the threaded rod 30. The rotation of the rotating ring 8 drives the rotation of the threaded rod 30 relative to the base 1 and the threaded sleeve 31, thereby realizing the displacement change of the threaded sleeve 31 in the vertical direction, so that the distance between the slice and the detection head 4 can be adjusted. One end of the guide rod is connected to the threaded sleeve 31 through a mounting bracket, and the other end is fixed to the base 1.

[0059] Based on the above embodiment, the working principle of the present application is as follows:

[0060] The slice is positioned in the positioning groove, and the spring rod 9 and the inner wall of the positioning groove cooperate to position and fix the slice in the positioning groove. Turn the handle 19, and the intermittent rotation of the rotating disc 7 is realized through the transmission of the gear assembly, so that the slice can be intermittently rotated to the position directly below the detection head 4 for detection. After the detection is completed, the slice is pushed out of the positioning groove by the thrust assembly and then removed. The slices in the subsequent positioning assemblies can be adjusted by the rotation of the rotating disc 7 through the gear assembly. In addition, the detection distance between the slice and the detection head 4 can be adjusted by adjusting the lifting of the lifting unit.

[0061] Based on the above embodiment, the advantages of the present application are:

[0062] (1) Through the cooperation between the spring rod 9 and the inner wall of the positioning groove, the slice can be positioned and fixed directly below the detection head 4, and can adapt to slices of different sizes. By designing the transmission ratio between the complete gear 12 and the incomplete gear 13, the rotating disc 7 is intermittently rotated, which can make the positioning assembly rotate to the position directly below the detection head 4 according to the detection requirement, so that the operator only needs to rotate the incomplete gear 13 to rotate the slice to the right position, so as to facilitate the accurate detection of the slice.

[0063] (2) Through the restoring force generated by the compression of the spring 14 in the damping assembly, the interaction force between the friction plate 15 and the bottom surface of the extension edge is increased, so that the gear assembly needs a certain starting force when rotating, that is, when the incomplete gear 13 is rotated, there will be a certain damping feedback. When detecting, the operator can judge whether the rotating disc 7 has been intermittently rotated through the feedback damping.
