Chemical fiber thread cutting machine

Abstract

The invention discloses a chemical fiber thread cutting machine in the technical field of chemical fiber thread production. The chemical fiber thread cutting machine comprises a machine base, whereinthe machine base is connected with a machine body through a fixing rod, the machine body is provided with a first cutting cavity and a second cutting cavity, the first cutting cavity is communicated with the second cutting cavity, the machine base is also connected with an air cylinder through a connecting rod, a telescopic end of the air cylinder is inserted in the first cutting cavity, the telescopic end of the air cylinder is connected with a connecting sliding block, the connecting sliding block is provided with a first cutting knife, and the second cutting cavity is internally in insertedconnection with a second cutting cavity. The chemical fiber thread cutting machine has the advantages that a plurality of chemical fiber threads are conveniently cut simultaneously, the threads are pulled conveniently through a power pulling roller, the cutting length is controlled by controlling the turning laps of the power pulling roller, the first cutting knife cooperates with the second cutting knife, a cutting principle is utilized for cutting, the wear caused by cutting with cutters is reduced, the service life is longer, and the maintenance and replacement are more convenient.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production, in particular to a chemical fiber cutting machine. Background technique [0002] Today's filament cutting uses a round shaft with a pulley on the workbench, a circular blade is fixed on the round shaft, and a motor is installed on the lower part of the workbench. The motor is driven by a belt to the installation circle. The circular shaft of the circular blade is connected with each other, and the circular blade is driven by a motor to rotate and cut. When cutting in this way, there will be constant high-speed friction between the circular blade and the chemical fiber yarn, which will generate heat, causing scorching or melting at the incision of the chemical fiber yarn, and causing serious quality problems for the head material of the chemical fiber yarn. It is not conducive to product quality; and in the whole chemical fiber cutting work, the motor drives the circular blade t...
