[0022] The rotating table 3 is cylindrical, and the sample holes 5 are evenly distributed in a circular shape on the rotating table 3. The support frame 8 is evenly distributed in a circular shape on the rotating frame 9, which can ensure that the punching block 6 or the sample hole 5 is in the working position with each rotation.

[0023] like Figure 4As shown in the figure, the clamping mechanism includes an arc-shaped clamping plate 4, and the clamping plate 4 is slidably arranged on the rotating table 3; a chute 15 is opened inside the rotating table 3, and a slider 16 is slidably arranged in the chute 15; a guiding groove 17 communicating with the chute 15 is opened on the rotating table 3, and the slider 16 passes through the guiding groove 17 and is fixedly connected with the clamping plate 4.

[0025] The principle of the present utility model

[0026] As Figures 1-2 shown in the figure is the structural diagram of the polymer sample preparation device. When preparing samples of polymers, a cylindrical polymer is placed on the rotating table 3. As Figure 4 shown in the figure, the screw rod 18 is turned. Driven by the slider 16, the two clamping plates 4 move towards the direction close to the polymer until the clamping plates 4 fixedly clamp the polymer. The hydraulic cylinder at the working position 7 is started to make the stamping block 6 move downward, and the polymer is blanked in cooperation with the sample preparation hole 5. The blanked samples fall into the collection box 11 through the dropping groove 14 and are collected.

[0027] When samples of different sizes need to be prepared, there is no need to disassemble the clamping mechanism. The controller 10 is used to start the first motor 12 to drive the rotating table 3 to rotate, so that different sample preparation holes 5 are located at the working position. At the same time, the controller 10 correspondingly controls the second motor 13 to start. Driven by the rotation of the rotating frame 9, the stamping block 6 corresponding to the sample preparation hole 5 rotates to the working position, quickly completing the replacement of the blanking die and greatly improving the sample preparation efficiency.
