The specimen is first manually loaded into a capsule and then the capsule is loaded into a pneumatic launch device. The capsule is pneumatically transported through a pipeline and reaches the designated position of the pipeline. Capsule-type pneumatic tube logistics mainly requires manual loading of a single specimen into a capsule for launch, and then taking out the specimen from the capsule after arriving at the receiving point. Both the loading and taking out processes require manual operation, which is inefficient. Summary of the Invention

[0023] See also Figures 1 to 3 As shown, a single-specimen pneumatic rotary circulating launching device includes a mounting base 1, on which a driving mechanism 2, a specimen loading wheel platform 3, a rotating shaft 4, a turntable 5, a detecting mechanism 6, a sealing mechanism 7, a conveying pipe 8 and a ventilation pipe 9 are provided. The specimen loading wheel platform 3 is arranged in the middle of the mounting base 1, and the sealing mechanism 7 is symmetrically arranged at both ends of the mounting base 1 and presses the specimen loading wheel platform 3 inwardly. The rotating shaft 4 passes through the sealing mechanism 7 and the specimen loading wheel platform 3 in turn and is connected to both ends of the mounting base 1. The driving mechanism 2 is arranged on one side of the mounting base 1 for driving the specimen loading wheel platform 3 to rotate. The turntable 5 is provided with a sealing mechanism 7. It is placed on the rotating shaft 4 and can rotate with the rotating shaft 4. The conveying pipe 8 is arranged at the top of the mounting seat 1 and one end of it passes through the top of the mounting seat 1 and the sealing mechanism 7 in sequence and extends to the inner surface of the sealing mechanism 7. The ventilation pipe 9 is arranged at the bottom end of the mounting seat 1 and corresponds to the conveying pipe 8 coaxially. One end of it passes through the top of the mounting seat 1 and the sealing mechanism 7 in sequence and extends to the inner surface of the sealing mechanism 7. A plurality of through holes 10 for placing specimens are provided axially on the specimen loading wheel 3. The detection mechanism 6 is arranged on the top of the mounting seat 1, and is used to detect the rotation angle of the turntable 5 and the specimens filled into the through holes 10.

[0024] In some embodiments, the driving mechanism 2 includes a motor mounting base 21, a motor 22, a driving gear 23, and a driven gear 24. The motor mounting base 21 is located on one side of the mounting base 1, and the motor 22 is located on the motor mounting base 21. The driving gear 23 is connected to the output end of the motor 22. The driven gear 24 is sleeved on the lower end of the specimen loading wheel 3 and meshes with the driving gear 23. The driving gear 23 and the driven gear 24 are driven by the motor 22, thereby causing the specimen loading wheel 3 to rotate.

[0025] In some embodiments, the specimen loading wheel 4 is convex-shaped. There are at least two through-holes 10 evenly arranged in a circular pattern on the specimen loading wheel 3. When the through-holes 10 rotate to be coaxial with the delivery pipe 8 and the ventilation pipe 9, air pressure is used to eject the specimen in the through-holes 10 along the delivery pipe 8.

[0026] In some embodiments, the upper diameter of the through hole 10 is larger than the lower diameter and is funnel-shaped. The lower diameter of the through hole 10 is larger than the specimen diameter and smaller than the specimen cover diameter. This structure allows the specimen to be hung on the through hole without being blocked during launch.

[0027] In some embodiments, the sealing mechanism 7 includes a positioning bolt 71, a compression spring 72, and a pressure plate 73. The positioning bolt 71 is threadedly connected to the mounting base 1 and extends at one end toward the specimen loading wheel 3. The pressure plate 73 is movably connected to the extended end of the positioning bolt 71 and abuts against the specimen loading wheel 3. The compression spring 72 is mounted on the positioning bolt 71 and positioned between the mounting base 1 and the pressure plate 73. The pressure plate 73 is semicircular in shape. The pressure of the compression spring 72 ensures that the pressure plate 73 is in airtight contact with the specimen loading wheel 3, preventing air leakage from affecting the launch force.

[0028] In some embodiments, the detection mechanism 6 includes a connecting plate 61, a turntable detector 62, and a specimen detector 63. The connecting plate 61 is disposed on the upper side of the mounting base 1. The turntable detector 62 is disposed on the connecting plate 61 and corresponds to the turntable 5. The specimen detector 63 is disposed above the specimen loading wheel 3 and corresponds to the through hole 10. The turntable detector 62 is used to detect the rotation angle of the turntable 5 and indirectly detects the rotation angle of the specimen loading wheel 3. The specimen detector 63 is used to detect whether the specimen is loaded into the through hole 10.

[0029] In some embodiments, scales are evenly distributed on the turntable 5. Each scale corresponds to a through hole 10. When the specimen loading wheel 3 rotates, the turntable 5 rotates accordingly. The detection mechanism 6 controls the rotation angle by detecting the scales, so that one of the through holes 10 can be coaxial with the delivery pipe 8.

[0030] In some embodiments, a compressed gas inlet 11 is provided on the delivery pipeline 8 for providing launching power.

[0031] The specific working process is as follows: the scale on the turntable 5 corresponds to the through-hole 10 of the specimen loading wheel 3. When the compressed air inlet 11 is energized, it is in the ventilation state. The compression spring 72 acts on the pressure plate 73, making the pressure plate 73 and the specimen loading wheel 3 tightly fit and prevent air leakage. When a specimen enters the through-hole 10, the specimen detector 63 detects that the specimen is loaded and sends a signal to the motor 22. The motor 22 drives the specimen loading wheel 3 to rotate through the driving gear 23 and the driven gear 24. The specimen loading wheel 3 rotates one position, and its rotation angle is one scale mark detected by the turntable detector 62. It enters the through-hole 10 of the next specimen loading wheel 3, and the loading cycle continues. When the through-hole 10 of the specimen loading wheel 3 reaches the launch position, that is, coaxial with the delivery pipe 8, compressed air is introduced into the ventilation pipe 9, and the specimen enters the delivery pipe 8 through the through-hole 10 and is transported to the designated position.

[0032] The present invention does not require manual loading of specimens into carriers for transportation, thus simplifying the transportation operation process, and can continuously launch and transport in a rotary manner, thereby improving operation efficiency.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
