Heat setting unit for monofilament production line

Abstract

The invention provides a heat setting device for a monofilament production line. The heat setting device belongs to the technical field of equipment for the monofilament production line. The heat setting device for the monofilament production line comprises a baking oven cover, a pressure roller, a square oil trough for containing high-temperature oil, and a setting motor which is fixed with the outer surface of the oil trough. The inner bottom of the oil trough is provided with an electric heater. The upper port of the oil trough is provided with a setting roller. The baking oven cover covers the oil trough and the setting roller. Two ends of the baking oven cover are provided with baking box holes for incoming and outgoing of a monofilament. The rotating shaft of the setting roller is rotatably connected with the upper end surface of the sidewall of the oil trough through a bearing. The setting motor drives the setting roller to rotate through a belt pulley assembly. The front end of the oil trough is provided with a height-adjustable supporting beam. The central axis of the supporting beam is parallel with that of the setting roller. Two ends of the supporting beam are connected with the front end of the oil trough through bolts. The bolts are vertically connected with the front end of the oil trough through threaded connection. A positioning nut which abuts against the lower end surface of the supporting beam sleeves each bolt. The heat setting device can apply an adjustable tensioning force on the monofilament, thereby greatly improving a heat setting effect.

Description

technical field [0001] The invention belongs to the technical field of equipment for a monofilament production line, and relates to a heat setting device for a monofilament production line. Background technique [0002] Monofilament production line: The primary filament extruded from the spinneret is first water-cooled and shaped, and then stretched, heat-set, and cooled in sequence, and finally the static electricity is eliminated and wound into a finished product. [0003] During the forming process of synthetic fibers, the spinning solution or melt is extruded from the holes, and then undergoes subsequent stretching after solidification. The molecular structure has been basically formed, but because some molecular segments are in a relaxed state, while others are in a state of In the tense state, there is uneven internal stress inside, and there are many defects in the crystallization in the fiber. In the wet-formed fiber, sometimes there are holes of different sizes. Th...

Problems solved by technology

[0004] Generally, the current heat setting device includes an oil tank and a setting roller on the upper end of the oil tank. In this heat setting device, the tension of the monofilament cannot be changed, the scope of application is low, and the heat setting effect is poor. In addition, the oil will flow out with the monofilament during heat setting. The oil tank drips to the ground, and people are prone to fall when they step on it, and the waste phenomenon is also serious, and the cost of oil is huge.
