Problems solved by technology

Its weak point is: 1, in the course of work, yarn sometimes breaks, and after yarn breaks, bobbin A9 still presses against on groove drum A6 and rotates, and the yarn that has been waxed passes through groove drum A6 together Friction and rotation will generate harmful gas, which will pollute the working environment and damage the yarn
Special personnel come to watch the work of the drum doffing machine. One is to increase the labor cost, and the other is that the staff are very prone to fatigue while holding the drum doffing machine.

Abstract

The invention discloses a device for automatically separating a bobbin from a groove drum after yarns of a groove drum doffer are broken. A separating unit is fixed on a rack and has a structure as follows: a coil holder is fixed on a shell and fixed with an electromagnetic coil, an electromagnet is sheathed in the electromagnetic coil in an inserting manner, a power on-off switch of the electromagnetic coil is arranged on the shell, a zigzag-shaped trigger rod is hinged on the shell, one end of a first tension spring acts on the shell, the other end of the first tension spring acts on the zigzag-shaped trigger rod, the electromagnet is hinged with a lever which is hinged on the shell and extends out of the shell to be opposite to a manual operation rod, one end of a second tension spring acts on the lever, the other end of the second tension spring acts on the shell or the coil holder, the rear part of the zigzag-shaped trigger rod is opposite to the power on-off switch of the electromagnetic coil, and the front part of the zigzag-shaped trigger rod extends out of the shell and is pressed below the yarns between a rear yarn guiding lug and a waxing shaft. According to the device, the environmental pollution is avoided, the labor cost is saved, the work efficiency is improved, the production cost is lowered simultaneously, and the yarns are prevented from being damaged to produce more defectives.

Description

Technical field: [0001] The invention relates to a device for automatically separating a winding shaft from a groove drum after the yarn is broken during the waxing process of the yarn on a drum winder. Background technique: [0002] Such as figure 1 , 2 When the existing groove drum doffing machine shown is waxing the yarn, after the yarn is released from the pay-off shaft A1, the yarn goes around the machine side thread lug A2, the thread wheel A3, the positioning thread lug A4, and the rear thread lug A4. Pass the wire ear A5 and the groove tube A6, and then wind on the bobbin A9, the yarn is pressed between the wax block A8 and the tray A12 on the waxing shaft A7, and the wax block A8 is inserted and sleeved on the tray A12 fixed on it. On the wax shaft A7, the winding shaft A9 is hinged on the winding bracket A10 and pressed against the groove cylinder A6, the groove cylinder A6 is driven by the motor to rotate, and the winding shaft A9 itself has no rotational power,...
