Abstract

The invention relates to an automatic opening and closing device for hank reels of a hank reeling machine. The hank reels are movably connected with a spindle through a parallelogram mechanism; an AB connecting rod in the parallelogram mechanism is connected with one push rod through a BE driving connecting rod; each push rod is fixedly connected with a nut which is connected with a belt pulley through a screw rod; and the belt wheels are synchronous toothed belt wheels. According to the automatic opening and closing device, rectilinear motion of a screw rod pair is used, the four-bar linkage hank reels are driven by the push rods, and expansion and reduction of the outer diameter of each reel are finished. The automatic opening and closing device has the advantages that the motor-driven degree of automation is high, the reel positioning accuracy is high, and the self-locking is reliable; the reels can be positioned in multiple appointed positions, so that requirements for different reel circumferences of various yarns in hank reeling can be met flexibly; and the device is simple in structure, convenient to mount and low in cost.

Description

technical field [0001] The invention relates to a skein stretcher of a yarn swinging machine, in particular to an opening and closing device for the skein stretcher of a swinging machine. Background technique [0002] The automatic opening and closing of the skein tension frame of the existing domestic yarn shaking machine is to adopt the artificial manual shaking wheel to drive the four-linkage method. The degree of automation is low, and the stretcher cannot meet the requirements of repeated positioning and high precision, and the mechanical structure is cumbersome and easy to break. The automatic opening and closing of the skein frame of the foreign yarn shaking machine adopts the method of adding a hydraulic pump station and a hydraulic cylinder to push the four-link method. The hydraulic seal is easy to leak, resulting in low repeat positioning accuracy of the stretcher, and the maintenance of the hydraulic system is complicated and expensive, and the equipment investm...
