Pressure-adjustable tobacco shred sample pressing device

The utility model relates to a pressure-adjustable tobacco shred sample pressing device, which comprises a sample presser and a sample cup, the sample presser comprises a pressure plate and a vertical rod arranged at the top of the pressure plate, and the pressure plate can extend into the sample cup; the vertical rod is detachably connected to the shell, the shell is movably provided with a weight, the lifting motor is arranged on the support, the output end of the lifting motor is connected with the transmission mechanism, the output end of the transmission mechanism extends into the hollow cavity, and the output end of the transmission mechanism is connected with the vertical rod. The output end of the transmission mechanism can be connected with the top of the shell in a clamped mode so that the shell can ascend and descend along the support. The weight can be taken out smoothly after sample pressing is completed, abrasion of the weight to the near-infrared spectrometer during follow-up detection is preve
