Description

Technical Field

[0001] This utility model belongs to the field of chlorophyll content detection technology, specifically relating to an automatic chlorophyll content detection device for fresh tea leaves. Background Technology

[0002] Hexanthol in fresh tea leaves is a low-boiling-point aromatic substance with a strong grassy aroma. It is the most prominent volatile aroma in fresh tea leaves, accounting for about 60% of the total volatile substances. During tea processing, such as the fixation step in green tea and Pu-erh tea, heat and enzymatic reactions cause some hexanthol to volatilize, while another part of hexanthol undergoes isomerization to form trans-hexanthol, which has a fresh aroma. This changes the aroma of the tea from grassy and unpleasant to fresh and fragrant.

[0003] To detect the chlorophyll content in freshly picked tea leaves, a gas chromatograph (GC) is used. First, a chlorophyll solution of the fresh tea leaves is prepared. This solution is then injected into the GC's detection port using a syringe to plot a sample curve. Next, a chlorophyll standard solution of known concentration is injected into the sample port, and the GC plots a standard curve. By comparing the sample curve with the standard curve, the chlorophyll content in the fresh tea leaves can be calculated. However, the aforementioned GC requires manual operation of the syringe, necessitating precise injection of the detection solution. Slight deviation can cause the needle to bend, and prolonged manual operation can lead to hand fatigue. To address these issues, a new automatic chlorophyll content detection device for fresh tea leaves is proposed. Utility Model Content

A clamping rod 55 is installed on the first slider 53 and the second slider 54. The automatic clamping mechanism 5 also includes a transmission spur gear 56 rotatably installed inside the first clamping seat 51 and the second clamping seat 52. A first rack 57 is fixedly installed on the first slider 53 and a second rack 58 is fixedly installed on the second slider 54. The transmission spur gear 56 meshes with the first rack 57 and the second rack 58. A first electric push rod 59 with a movable end connected to the first slider 53 is fixedly installed inside the first clamping seat 51 and the second clamping seat 52.

[0041] In this embodiment, the box-type gas chromatograph 1 is first adjusted, the dust cap 4 at the top of the detection port 3 is opened, and the cyanidin sample solution is injected into one of the detection ports 3 through a syringe. Then, the cyanidin sample solution is injected into the other detection port 3. The syringe is located in the middle of the clamping rod 55. The first electric push rod 59 inside the first clamping seat 51 and the second clamping seat 52 is activated. The output shaft of the first electric push rod 59 retracts, driving the first slider 53 to move closer to the second slider 54.

[0045] In this embodiment, the second electric push rod 10 on the reinforcing base 8 is activated. The moving end of the second electric push rod 10 retracts, driving the reinforcing plate 9 closer to the reinforcing base 8. The linkage block 12 enters the linkage hole 11, limiting the clamping rod 55 and firmly connecting the other side of the clamping rod 55, thus firmly clamping the syringe.

[0046] like Figure 7 As shown, a third electric push rod 13 is provided on one side of the first clamping seat 51, located above the box-type gas chromatograph 1. A lifting seat 14 is installed on one side surface of the first clamping seat 51, and a lifting block 15 is installed on one side surface of the second clamping seat 52.

Guide blocks 18 are symmetrically installed on the lifting block 15, and the guide blocks 18 are slidably connected to the guide grooves 17.

[0047] In this embodiment, the moving end of the third electric push rod 13 retracts, causing the lifting block 15 to move downwards and approach the lifting seat 14. The guide block 18 moves downwards along the inner wall of the guide groove 17, causing the second clamping seat 52 to approach the first clamping seat 51, pressing the clamped syringe and injecting the solution into the detection port 3.

[0048] like Figure 8 As shown, a protective shell 19 is installed on the upper surface of the box-type gas chromatograph 1. A rotating seat 20 connected to the bottom end of the third electric push rod 13 is provided above the protective shell 19. A drive motor 21 is installed inside the protective shell 19. The output shaft of the drive motor 21 is connected to the lower surface of the rotating seat 20. An annular groove 22 is opened on the upper surface of the protective shell 19. Reinforcing blocks 23 are symmetrically installed on the lower surface of the rotating seat 20, and the reinforcing blocks 23 are slidably connected to the annular groove 22.

[0049] In this embodiment, the drive motor 21 inside the protective shell 19 is activated. The output shaft of the drive motor 21 drives the rotating seat 20 to rotate, which in turn drives the third electric push rod 13 to approach the top of one of the detection ports 3 or the top of the other detection port 3. The reinforcing block 23 slides along the inside of the annular groove 22 to ensure that the rotating seat 20 rotates horizontally.
