Yarn retention device

Abstract

The invention relates to a yarn ending device. The yarn ending device comprises a rotatable open type yarn bank provided with a plurality of containing cavities, an air suction pipeline fixed to the center of the open type yarn bank and an inclined track located on the lower portion of the bottom of the open type yarn bank. An outlet allowing bobbins to go in and out is formed in the outer side of the open type yarn bank. The outer side of the air suction pipeline is provided with a core tube which is integrated with the open type yarn bank. The bottom of the core tube is provided with a rotary plate, and the periphery of the rotary plate is serrated. One side of the rotary plate is provided with a push plate, and the inner side of the push plate is provided with ratchets. The arc-shaped front side of the push plate is matched with a tray. The rear side of the push plate is connected with an air cylinder. The ratchets are matched with the rotary plate to push the open type yarn bank to rotate and also drive the tray with the bobbins to move towards the inclined track. An exhaust inlet of the air suction pipeline directly faces the small end of the bobbin which is about to move onto the inclined track. The yarn ending device has the beneficial effects that the structure is simple, and the bobbins are separated from the tray smoothly after yarn is ended.

Description

technical field [0001] The invention relates to a yarn end retention device. Background technique [0002] The yarn bobbin that finds the yarn end needs to be left before the bobbin can be sent to the yarn loading machine. The yarn end in the bobbin needs to be taken out, and the bobbin is separated from the tray, and the tray is reused. Manual detachment is cumbersome, which is not conducive to Assembly line operation, so it is necessary to design a convenient and quick yarn end retention device. Contents of the invention [0003] Based on the above problems, the present invention provides a yarn end retention device. [0004] A technical solution adopted by the present invention to solve the technical problem is: a yarn head retaining device, which includes a rotating open yarn storehouse with several cavities, a suction duct fixed in the center of the open yarn storehouse and an open The inclined track below the bottom of the yarn storehouse is used to separate the bo...
