Problems solved by technology

The disadvantages of this shredder are: 1. Only one blade is installed in the wire guide groove. When the tow is driven in, it does not directly hit the blade but hits the other side of the wire guide groove without a blade. Cannot be effectively cut off instantly
2. The wire catcher adopts a rotary

Embodiment Construction

[0012] As shown in the figure, a passive shredder of the present invention includes a knife rest 7, two shred blades 6, a safety knife cover 5 and a wire catcher; The cross is obliquely installed on the knife rest 7, and forms the wire guide groove 4 with the notches on the knife rest 7 and the safety knife cover 5. In order to ensure that the silk catcher can catch the tow 2 smoothly, the silk catcher adopts pneumatic control.

[0013] The wire catcher comprises a cylinder base 11, a cylinder 14, a screw rod 8 and a spring 9; wherein the cylinder 14 is installed on the cylinder base 11, and the wire catcher 8 is installed on the upwardly extending boss of the cylinder base 11 with a support shaft 10, catching The lower edge of the front end of the screw rod 8 is provided with a slot for catching wire, and the boss on the lower edge of the rear end is placed in the screw catching rod shelf 13 which is integrated with the piston 18, so that the screw rod 8 follows the up and dow...

Abstract

The invention discloses a passive yarn cutter which is characterized by comprising a cutter rest, a yarn-cutting blade, a safe cutter cover and a yarn-capturing device; the yarn-cutting blade is obliquely arranged on the cutter rest; the cutting edge thereof is scissor-type and form a yarn-leading groove with the cutter rest and a notch of the safe cutter cover; and the yarn-capturing device which arranges filament bundles into the yarn-leading groove is arranged at the front of the cutter rest. Compared with the prior art, the yarn cutter has the advantages of fast yarn capturing and yarn cutting, high success ratio of yarn cutting, simple structure and stable quality of products.

Description

technical field [0001] The invention relates to a shredder in a textile machine, in particular to a shredding device for catching and cutting silk threads during the spinning process of chemical fiber filaments. Background technique [0002] During the spinning process of the automatic doffing false twist texturing machine, the chemical fiber filament needs to be wound onto the bobbin through the winding mechanism to complete the winding of the thread. When a bobbin is fully wound, it is necessary to automatically replace the bobbin through a series of mechanical action combinations. During this process, the filaments must be cut and the winding stopped. On the one hand, the broken filaments are sent to the suction device for the spinning of empty bobbins, and on the other hand, new bobbins are replaced. [0003] The device used to cut the filament is called the shredding device. Usually, there are two types of shredding devices, one is active shredding, that is, after the...
