Secondary sizing device of glass fiber

Abstract

The invention provides a secondary sizing device of glass fiber. The secondary sizing device of the glass fiber comprises a pulp pool, a sizing system, a pulp pool heating system and a filtering device, wherein the sizing system comprises a sizing roller set and a pulp pouring device, and the sizing roller set is arranged in the pulp pool, is used for sizing warp yarns of the glass fiber, and comprises at least three sequentially-arranged sizing rollers; the pulp pouring device comprises a pulp pouring pipe and a pulp pouring head; the pulp pool heating system comprises a heat preservation layer and a temperature adjusting device, the heat preservation layer is arranged on the outer side of the pulp pool in an enclosing mode, and the temperature adjusting device comprises a temperature sensor, a controller and a temperature adjusting actuating mechanism; the filtering device is used for filtering pulp in the pulp pouring device and is fixedly arranged on the pulp pouring pipe. According to the secondary sizing device of the glass fiber, the pulp pool heating device is arranged, the temperature of the pulp in the pulp pool can be adjusted, the situation that the quality of glass fiber cloth is affected by pulp oxidation film forming is avoided, and the production cost is reduced.

Description

technical field [0001] The invention relates to warp yarn sizing equipment, in particular to a glass fiber secondary sizing device. Background technique [0002] When weaving glass fiber cloth on the loom, the warp yarn, the heald and the reed will have severe and rapid friction. In order to avoid damage to the yarn bundle, another layer of slurry is applied to the yarn to obtain a protective effect. Also known as secondary sizing. [0003] At present, the secondary sizing device for sizing mainly adopts upper and lower sizing tanks, the upper sizing tank is used for warp yarn sizing, and the lower sizing tank is used for heating the size and pumping the size to the sizing tank through the size pump to circulate the size. The upper sizing tank has a roller that rotates at high speed to stir the slurry, while the liquid level in the lower sizing tank is calm, the slurry is in contact with air for a long time to oxidize the conjunctiva, and the lower sizing tank will circulat...

AI Technical Summary

Problems solved by technology

The upper sizing tank has a roller that rotates at high speed to stir the slurry, while the liquid level in the lower sizing tank is calm, the slurry is in contact with air for a long time to oxidize the conjunctiva, and the lower sizing tank will circulate the slurry in the conjunctiva to the sizing tank to The produced glass fiber cloth causes sizing scars and affects the quality. In order to eliminate the conjunctiva, the operator needs to clean the conjunctiva continuously; at the same time, the temperature loss of the slurry during the circulation process makes the temperature of the slurry circulated to the sizing tank lower than the ideal temperature, which affects sizing Quality, and each production also needs to prepare the slurry of the lower trough, which increases the production cost
