【摘要】：通過(guò)對(duì)D型打結(jié)器空間傳動(dòng)方案改進(jìn)提出了雙齒盤驅(qū)動(dòng)打結(jié)器,將驅(qū)動(dòng)夾繩器的空間傳動(dòng)布置在打結(jié)器支架的另一側(cè),將進(jìn)口打結(jié)器支架一組空間交錯(cuò)軸角度關(guān)系簡(jiǎn)化為平面相交軸角度關(guān)系,降低了打結(jié)器支架的加工難度,克服了進(jìn)口打結(jié)器空間交錯(cuò)軸錐齒輪齒廓設(shè)計(jì)與制造難的問(wèn)題,便于批量化生產(chǎn)。通過(guò)將蝸桿與斜齒輪的傳動(dòng)比調(diào)整為1∶3使原四槽口夾繩盤改進(jìn)為三槽口夾繩盤,并匹配設(shè)計(jì)了夾繩盤、打結(jié)嘴和刀臂的運(yùn)動(dòng)時(shí)序,建立了雙齒盤驅(qū)動(dòng)打結(jié)器的結(jié)構(gòu)模型。與進(jìn)口打結(jié)器的成結(jié)動(dòng)作對(duì)比試驗(yàn)表明雙齒盤驅(qū)動(dòng)打結(jié)器的空間傳動(dòng)方案改進(jìn)合理,驅(qū)動(dòng)夾繩器、打結(jié)嘴和刀臂的運(yùn)動(dòng)時(shí)序匹配設(shè)計(jì)正確,夾繩和割繩動(dòng)作比進(jìn)口打結(jié)器更優(yōu),夾繩時(shí)捆繩直接入夾繩盤槽口,割繩時(shí)捆繩靠近刀片中間位置。室內(nèi)臺(tái)架的打結(jié)試驗(yàn)表明雙齒盤驅(qū)動(dòng)打結(jié)器的成結(jié)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.
