Problems solved by technology
[0002] The yarn bobbin on the spinning frame needs to be removed after it is full of yarn, and replaced with an empty bobbin to continue spinning. This process is usually manually removed and replaced, and the manual operation efficiency is extremely low. Winding on the spindle, so that the empty bobbin is placed on the spinning frame spindle to continue winding
However, due to the fine and light characteristics of the yarn, the operator is likely to fail to keep the tail yarn wound on the spindle during operation, resulting in an increase in the breakage rate of the start-up, wasting a lot of working time to manually start the joint, and affecting the overall work efficiency

Embodiment Construction
[0016] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.
[0017] like Figure 1-Figure 3 As shown, the yarn clamping synchronous mechanism of the doffing machine of the present invention includes a mounting frame 1 on which a crossbeam 2 is installed. Both ends of the crossbeam 2 are equipped with sprockets 3, and one of the sprockets 3 is connected to a drive The motor 4 is driven by the drive motor 4 during work. The chain 5 is installed on the sprocket 3. Several tail yarn cutting mechanisms and tail yarn fixing mechanisms are installed on the chain 5. The tail yarn fixing mechanism is located in front of the tail yarn cutting mechanism. .
[0018] The tail yarn fixing mechanism includes a yarn clamping device and a yarn clamping device mounting seat, and the yarn clamping device is installed on the yarn clamping device mounting base.
[0019] The yarn cl...

The invention relates to a yarn clamping synchronization mechanism of a doffer. The yarn clamping synchronization mechanism comprises a mounting frame, wherein a cross beam is mounted on the mounting frame; chain wheels are respectively mounted at the two ends of the cross beam; one of the chain wheels is connected with a driving motor; a chain is mounted on the chain wheels; a plurality of tail yarn shearing mechanisms and tail yarn fixing mechanisms are mounted on the chain; and the tail yarn fixing mechanisms are positioned in the front of the tail yarn shearing mechanisms. Tail yarns are clamped on clamping springs without sliding off from ingots after passing through guide grooves and being cut by cutters, so that the tail yarns are wound on the ingots; when empty yarn tubes are inserted in the ingots, the tail yarns are not required to be wound manually, so that the head leave rate of the yarns is increased when a spinning frame is started, broken heads are decreased, the yarn head connecting time is saved when the spinning frame is started, and the working efficiency is improved.
Description
technical field [0001] The invention relates to a yarn clamping synchronous mechanism of a doffer, and belongs to the technical field of auxiliary equipment of a doffer. Background technique [0002] The yarn bobbin on the spinning frame needs to be removed after it is full of yarn, and replaced with an empty bobbin to continue spinning. This process is usually manually removed and replaced, and the manual operation efficiency is extremely low. Winding on the spindle, the empty bobbin is placed on the spinning frame spindle to continue winding. However, due to the thin and light characteristics of the yarn, the operator is prone to the tail yarn not being wound on the spindle during operation, resulting in an increase in the breakage rate at start-up, wasting a lot of working time to manually start the joint, and affecting the overall work efficiency. [0003] Based on this, the present invention is proposed. Contents of the invention [0004] Aiming at the above-mention...
