[0001] The utility model relates to the technical field of silk strand strip slicing processing, in particular to an underwater strip-drawing roller device for polyester pelletizing. Background Art
[0002] The polyester raw material is esterified and polycondensed to form a polymer melt, which is solidified by air sprayed out from the spinneret and then further cooled by desalted water to form silk strands. The silk strands are subsequently pelletized, dried, screened and finally transported to the slicing silo.
[0003] The existing polyester pelletizing wire strand pressing roller device is often directly fixed on the upper end of the water cooling tank and cannot be easily moved. In addition, the pressing roller device usually cannot adjust the height, which makes it difficult to reasonably guide the wire strands of different specifications. Therefore, in the actual pelletizing process, due to the disadvantages of the fixed pressing roller device, it is difficult to comb the disordered wire strands, which is easy to cause oblique cuts and abnormal slices, and even cause the pelletizer to malfunction, wasting a lot of manpower and material resources, affecting the polyester wire strand conveying effect and slice quality. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the invention

[0035] The cross bar 6 can rotate to adjust the angle of the pressure roller assembly, and the pulley 3 rolls to realize the movement of the pressure roller assembly, which is convenient for the re-arrangement of the chaotic silk strands, reduces the combing time, and improves the work efficiency and product quality. The telescopic drive device 7 can drive the roller frame to move to adjust the height of the pressure roller rod 11 to adapt to drive devices of different specifications. The rotating setting of the pressure roller rod 11 realizes the dynamic displacement of the silk strands, while avoiding excessive wear of the pressure roller rod 11, ensuring the slicing quality, and minimizing the generation of abnormal slicing.

Furthermore, a guide pad 10 is laid on the inner bottom of the water-cooling groove 1, and a plurality of arc-shaped guide grooves 1001 are arranged on the upper side of the guide pad 10. The guide grooves 1001 are arranged corresponding to the annular grooves 1101, and the annular grooves 1101 and the guide grooves 1001 cooperate to guide the wire strands, so that the wire strands can be further corrected in displacement.
[0037] like Figure 1-Figure 5As shown, a first bearing 5 is disposed in the upper bearing seat 15 , and the first bearing 5 is sleeved on the cross bar 6 , so that the first bearing 5 enables the cross bar 6 to rotate.

The first limit block 19 and the second limit block 20 form a 90° angle, so that the limit rod 18 can rotate within a range of 270°.
[0043] like Figure 1-Figure 5As shown, the magnetic cylindrical first limit block 19, the second limit block 20, the third limit block 21 and the fourth limit block 22 all have internal threads, and the sides of the first limit seat 12 and the second limit seat 13 and both sides of the end of the limit rod 18 are provided with matching threaded rods.
