A nylon monofilament constant tension wire feeder

Abstract

The invention discloses a constant tension filament feeder for a nylon monofilament. The constant tension filament feeder comprises monofilament pan heads, motors, input pulleys, output pulleys, weight pulleys, sensor groups, input sensors, output sensors and controllers, wherein the nylon monofilament is wound inside the monofilament pan heads and connected with the motors in a transmission manner; the nylon monofilament sequentially passes through the input pulleys, the weight pulleys and the output pulleys and is fed to a nylon molding machine after being led out from the monofilament pan heads; the input sensors detect the rotating speeds of the input pulleys; the output sensors detect the rotating speeds of the output pulleys; each sensor group at least comprises an upper limit sensor and a lower limit sensor, and the controllers are connected with the motors and control the rotating speeds of the motors according to signals of the input sensors, the output sensors and the sensor groups, so that the weight pulleys are between the upper limit sensors and the lower limit sensors. Compared with the prior art, constant static tension can be achieved in a pulley weighting manner by control, so that the product quality is ensured.

Description

technical field [0001] The present invention relates to the field of feeding and supplying nylon monofilament, and more specifically relates to a nylon monofilament constant tension wire feeding machine, which is used to supply nylon monofilament to a nylon molding machine with constant tension. Background technique [0002] During the molding process of the nylon molding machine, if the tension of the nylon monofilament feeding is different, it will cause the consequences of different zipper widths on the formed nylon sprockets, which greatly increases the defective rate of the nylon zipper and seriously affects The quality of the nylon zipper is compromised, and it will be difficult to bite after the two nylon chain teeth mesh with each other. [0003] Please refer to the Chinese invention patent publication CN1421371A related to the method and device for stabilizing the wire feeding of the zipper forming machine, which uses the outer edge of the wire frame of the zipper f...
