Polyurethane is a strong and tough material, so the performance of polyurethane will directly affect the strength of carbon fiber. Therefore, sampling and testing are required during its preparation.

Generally speaking, sufficient samples need to be taken in experiments or production to ensure the accuracy and reliability of the test results. Therefore, multiple groups of samples are generally required. If the sampling tube is difficult to replace during this process, it is easy for samples to remain in the sampling tube and mix, affecting the accuracy of sample testing. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects: the polyurethane automatic sampling mechanism for carbon fiber not only improves the convenience of replacing the sampling tube, but also improves the height adjustment ability and sample cup clamping ability of the sampling mechanism;

[0014] (1) The embedding groove is opened inside the connection block, and then the connection plate is used to complete the connection and installation between the insertion block and the sampling tube. At this time, when assembling the sampling tube, the insertion block can be inserted into the embedding groove. After the insertion is completed, the through groove is flush with the installation hole on the side of the connection block, and the bayonet is inserted through the installation hole and the through groove. Then, the two ends are threadedly locked with locking nuts. Therefore, the sampling tube can be assembled. When sampling, the sampling tube reaches the inside of the sample cup, and then the material is fed through the sampling hole to the inside of the sampling tube for collection. When taking out the sample, the conical block can be rotated to make the thread column leave the inside of the thread groove. When replacing, the locking nut is disassembled and the bayonet is taken out, and then the insertion block is removed from the inside of the connection block. Then, the sampling tube can be assembled in the same way, thereby improving the overall convenience during the work process;

[0015] (2) The guide block is used to connect the threaded block and the horizontal plate. When the servo motor is working, the threaded rod can be driven to rotate. At this time, the threaded block and the threaded rod cooperate with each other to form a thread path. At this time, the guide block guides along the guide groove, so the height of the horizontal plate can be adjusted. The height adjustment position is monitored by the position sensor, which facilitates the adjustment of the sampling height.

[0016] (3) The fixing plate is installed on one side of the top of the supporting bottom plate, the sampling cup is placed between the fixing plates, and then the telescopic rod is started to drive the clamping plate to move, and the clamping plate is used to clamp the sampling cup. When clamping, the protective pad directly contacts to form a clamping protection, and the retaining spring is correspondingly compressed to form a certain buffer protection, thereby improving the overall sample cup clamping ability during the working process.
