Description

Be used for long filament production winder chuck end cover

Technical Field

The utility model relates to a chemical fibre automated production field, more specifically say, it relates to one kind and is used for long filament production winder chuck end cover.

Background

At present, the parallel winding and spooling of high-speed spinning in the chemical fiber field are mainly finished by winding machines, each winding machine is provided with two chucks, the yarn can be automatically wound into a finished spinning cake, and the winding is automatically switched between the two chucks. The yarn is wound on a special paper tube, the paper tube is sleeved on the chuck, the paper tube is tensioned through the chuck tensioning block, and after the automatic winding of one chuck is finished, the other chuck is automatically switched to continue to automatically wind. After the yarns are wound, compressed air is introduced from the tail part of the chuck, the air passes through an air inlet hole in the inner wall of the chuck to act on the wedge-shaped block, the wedge-shaped block moves towards the pressure spring and compresses the pressure spring, the tension block loosens and contracts towards the inner part of the chuck, the paper tube can smoothly loosen the tube, and then the finished spinning cake is withdrawn. Such a chuck has a few drawbacks: when the air leakage occurs to the chuck, the air pressure of the compressed air introduced from the tail of the chuck is generally constant, and the air pressure of the compressed air cannot or cannot completely retract the tension block, so that the paper tube is clamped on the chuck and cannot be loosened, and only 12 finished spinning cakes can be cut off by a cutter every time when the situation occurs, and the loss is large.

SUMMERY OF THE UTILITY MODEL

The utility model provides a be used for filament production winder chuck end cover, to when the inside sealing member of chuck damaged and arouse gas leakage trouble appearing, can get off the smooth back of paper tube on the chuck.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a be used for filament production winder chuck end cover, include the end cover body and with end cover body integrated into one piece stretch the board in, the size of end cover body is greater than stretch the size in, stretch the board in can go deep into inside the chuck and laminate with the chuck inside wall, all be equipped with gas passage on end cover body and the interior board of stretching, be connected with the air pipe connector on the gas passage of end cover body. Therefore, in the production process, the damage of a sealing element inside the chuck occurs to cause air leakage, when the paper tube is blocked on the chuck and cannot be loosened, the original end cover of the chuck head is removed, the end cover is replaced, the compressed air hose is connected, a large amount of compressed air is introduced from the air pipe joint on the end cover, the air inflow is far larger than the air leakage, the air passes through the air inlet hole in the inner wall of the chuck and acts on the wedge-shaped block, the wedge-shaped block moves towards the direction of the pressure spring and compresses the pressure spring, the tension block is loosened and shrinks towards the inside of the inner chuck, and the paper tube can be smoothly loosened.

Preferably, the end, far away from the end cover body, of the gas channel on the inward extending plate is in threaded connection with the partition plate, a plurality of vent holes communicated with the gas channel are formed in the partition plate, a rubber pad used for shielding the vent holes is further arranged on one side, far away from the gas pipe joint, of the partition plate, a through hole is formed in the middle of the rubber pad, and a screw penetrates through the through hole and the partition plate to fix the rubber pad on the partition plate. The end cover can be directly installed at the head of the chuck, under a normal working state, namely, the sealing element in the chuck is well sealed, compressed air is introduced from the tail of the chuck, the rubber pad on the end cover blocks the vent hole in the partition plate, the compressed air is prevented from leaking through the vent hole in the partition plate, the compressed air acts on the wedge block, the wedge block moves towards the direction of the pressure spring and compresses the pressure spring, the tensioning block is loosened and shrinks towards the inside of the inner chuck, and the paper tube can be smoothly loosened. When the sealing element inside the chuck is damaged to cause air leakage, and the paper tube is blocked on the chuck and cannot be loosened, a large amount of compressed air can be directly introduced from the air pipe joint at the head of the chuck, so that the air input is far greater than the air leakage, the compressed air passes through the through hole in the partition plate to act on the rubber pad, the air pushes the peripheral part of the rubber pad to be away from the air vent, the air enters the chuck and further acts on the wedge block, the wedge block moves towards the direction of the pressure spring and compresses the pressure spring, the tension block is loosened and shrinks towards the inside of the inner chuck, and the paper tube can be smoothly loosened.

Preferably, an annular groove is formed in the side wall, attached to the chuck, of the inner extending plate, and an annular sealing ring is embedded in the annular groove. Therefore, the sealing ring can increase the sealing performance between the end cover and the chuck, and gas is prevented from leaking from a gap between the end cover and the chuck during inflation.

To sum up, the utility model discloses following beneficial effect has: aiming at the problem that the air leakage fault is caused by the damage of the sealing element in the chuck, the paper tube on the chuck can be smoothly withdrawn, the operation is simple and convenient, and the manpower and material resources are saved.
