Abstract

The utility model relates to a yarn-saving winding head for an automatic cone winder, characterized in that a pressing plate screw rod is movably assembled with a yarn saving device which is fixed via a check ring and screws. When the end is connected, a shear cam is laid down and the yarn saving device is pressed on the upper side of a cop under the action of a pressing spring. Connecting flange with the lower induced draft is additionally provided with a limit plate and is fixed by the screws for limiting the closing degrees of an air door and forming a normally-opened state. The pendulum hook of a yarn clamping device with a pendulum cover is moved backward for making the air inlet of the pendulum cover and the opening degree of the upper opening of air pipe adjusted from full opening to 1/2 open degree. The winding head has the advantages of convenient modification, no influence for the performance of the original device, reasonable induced draft selection, no unwinding for the cop, and thread waste saving from 40 to 50%. Each machine can save the yarn from 1000 to 1500 kilograms and be suitable for the West Germany 238 type machine.

Description

Yarn-saving winding head for automatic cone winder

The utility model relates to a kind of automatic winder winding head, is a kind of automatic winder winding head with the joint yarn feeding device.

At present, domestic introduction automatic winder kind is a lot, its winding head structure is roughly the same, all be by the guide transmission device, twist with the fingers knot mechanism, the tension force clearing, the yarn storehouse, air valve openers etc. are partly formed, the nearly cone yarn of last suction arm rest holds loose thread and sends into sth. made by twisting knot chamber, under inhale arm and the cop loose thread is inhaled toward sending into twisted with the fingers the knot chamber, under system controlled by computer, finish yarn feeding by machinery, cut off, yarn clipping, twist with the fingers the knot overall process, because covering yarn gripper and inhale on the excessive cop of arm suction down, pendulum is provided with yarn saving device again, cause suction tail yarn long, the good yarn unwinding of part has become hard waste, and about 2.2 kilograms of hard wastes are produced in every machine per tour according to statistics, produce about 2250 kilograms of hard wastes per year, the wasting of resources is big, the cost height.

The purpose of this utility model provides some joint yarn measures, improves existing automatic winder winding head, and is long to solve the tail yarn, makes the good yarn of part become hard waste, and the wasting of resources is big, shortcomings such as cost height.

The purpose of this utility model is achieved in that existing winding head air valve opener, the yarn storehouse, pendulum covers yarn gripper, the tension force clearing, twist with the fingers the knot parts, the pressing plate screw rod, under inhale arm, last suction arm, the guide transmission device, twist with the fingers the knot camshaft, weft cutter cam, cop, loose thread, air duct, air door, butt flange, screw is formed constant, movable assembling one yarn saving device on the pressing plate screw rod, it is by back-up ring and screw retention, when replace tubes yarn or broken end, weft cutter cam puts down, and the pressured bullet effect of yarn saving device is pressed in cop top, under inhale arm and hold loose thread, cop is difficult for unwinding, finishes when twisting with the fingers knot, and weft cutter cam resets, lift yarn saving device again, do not influence former machine performance; On following air draught butt flange, increase positioning plate, it leans on screw retention, and to limit throttle opening,, pass dead three-state little by opening greatly, opening changes into open greatly, opens little two states, becomes the standard-sized sheet attitude; It is constant that pendulum covers yarn gripper airduct, Bai Gai, torsion spring, pin, swing arm, its shape and structure of swing hook, just will move behind the swing hook, make swing hook and pin move after contact time, shorten, make Bai Gai air port and the airduct aperture that overlaps suitable for reading be transferred to maximum by standard-sized sheet and can only reach 1/2, can reduce airduct suction suitable for reading like this, under the situation that guarantees the loose thread inhalation rate, can prevent the unwinding of yarn shed tube yarn again, shortened the tail yarn length.

This utility model compared with prior art has the following advantages: 1) former automatic winder parts shape and structure is constant, only increases individual parts or adjusts the individual parts activity thresholds, and it is convenient to transform; 2) transform parking period weak point, small investment, instant effect; 3) do not influence the original equipment performance after changing; 4) change every the machine in back and can reduce hard waste 40--50%, every machine can save yarn 1000--1500 kilogram every year.
