【摘要】：通過對D型打結器空間傳動方案改進提出了雙齒盤驅動打結器,將驅動夾繩器的空間傳動布置在打結器支架的另一側,將進口打結器支架一組空間交錯軸角度關系簡化為平面相交軸角度關系,降低了打結器支架的加工難度,克服了進口打結器空間交錯軸錐齒輪齒廓設計與制造難的問題,便于批量化生產。通過將蝸桿與斜齒輪的傳動比調整為1∶3使原四槽口夾繩盤改進為三槽口夾繩盤,并匹配設計了夾繩盤、打結嘴和刀臂的運動時序,建立了雙齒盤驅動打結器的結構模型。與進口打結器的成結動作對比試驗表明雙齒盤驅動打結器的空間傳動方案改進合理,驅動夾繩器、打結嘴和刀臂的運動時序匹配設計正確,夾繩和割繩動作比進口打結器更優(yōu),夾繩時捆繩直接入夾繩盤槽口,割繩時捆繩靠近刀片中間位置。室內臺架的打結試驗表明雙齒盤驅動打結器的成結率為100%。
[Abstract]:By improving the space drive scheme of D type knotting device, a double tooth disk drive knotting device is proposed. The space drive of the drive rope clamp is arranged on the other side of the tie holder. This paper simplifies a group of spatial staggered axis angle relations of imported knotter bracket to plane intersecting axis angle relation, reduces the processing difficulty of the knotter bracket, and overcomes the problem of the difficult design and manufacture of the bevel gear profile of the imported knotter space staggered shaft. By adjusting the transmission ratio of worm and helical gear to 1:3, the original four-slot clamping rope disc is improved to three-notch rope clamping disc, and the motion timing of clamping disc, knot mouth and knife arm is matched. The structure model of the double tooth disc driven knotting device is established. The results of the comparison test with the imported knotting device show that the spatial transmission scheme of the double tooth disc driven knotting device is improved reasonably, and the rope clamping device is driven. The timing matching of the movement of knotted mouth and knife arm is correct, the action of clamping rope and cutting rope is better than that of the imported knotting device, and when the rope is clamped, the rope is directly inserted into the slot of the clamping rope disc. The tie rope is close to the middle position of the blade when the rope is cut. The knot test of the laboratory bench shows that the knot forming rate of the double tooth disc driven knotting device is 100.
