Problems solved by technology

[0002] The short-cut water coating system has undergone three improvement processes, from roller coating to conventional spray head water coating to conventional spray plus water vapor mixed coating water; roller coating adopts a large roller installed in the water tank, which is tumbling according to the motor speed , the yarn rubs through the upper end of the roller, and the water is coated at the moment of friction. This water coating mode is gradually replaced by the conventional spray head due to the large water flow, poor uniformity, inconvenient operation, and potential safety hazards.
Although the conventional spray head is superior to the water application method of roller coating to a certain extent, the spray head is easy to block and the divergence angle is not enough, etc., still cannot meet the requirements of uniformity control of chopped particle size
At present, the short-cut water coating system mainly uses conventional spray and water vapor mixing methods to achieve the spray effect. However, when conventional spray and water vapor mixing methods are used to spray, due to the low pressure of conventional spraying, the uniformity of water coating is poor, and the number of spray heads in the water vapor mixing method is small and the spray Unreasonable placement of the position will often make the water coating effect of the yarn less than the effect of a reasonable spray
[0003] In actual production, the chopping water coating system often has the following problems: when each bundle of yarn passes through the water coating box, the spray effect is uneven, and the structure of the spray box is unreasonable, causing the mist to flow out to the steel platform; the yarn enters the water coating box. Single-row porcelain eye design results in wide yarn distribution, the spray head cannot spray the yarn, and the water coating efficiency is low
The water coating equipment uses the rotation of the water coating roller to coat the glass fiber with water, but there are problems such as uneven water coating and insufficient water coating

Abstract

The invention relates to a water coating system of glass fiber chopped yarns. The water coating system comprises a water coating box body, and the top of the water coating box body is provided with awater coating tank cover. The water coating system is characterized in that the water coating system also comprises a water inlet pipe, an air pipe, water-air pipelines and double-fluid spray heads; the water inlet pipe is positioned at one side of the water coating box body; the air pipe is positioned at the other side of the water coating box body; the water-air pipelines are connected between the water inlet pipe and the air pipe; the water-air pipelines are positioned in the water coating box body; a valve and a plurality of double-fluid spraying heads are arranged in each water-gas pipeline; one end of the water-coating box body is provided with an upper rows and a lower rows of porcelain eyelets for yarns to enter the water-coating box body; the other end of the water-coating box body is provided an upper row and a lower row of porcelain eyelets for the yarns to leave the water-coated box body; the water tank cover has a structure that the middle part id high and two end parts are low; and the water coating box cover is made of a transparent material. The invention also provides a water coating method of the water coating system. According to the invention, the water coatingof the chopped yarns is more uniform, and the stability of product quality is ensured.

Description

technical field [0001] The invention relates to a water coating system for chopped glass fiber yarns, which is used for the water coating steps of chopped glass fiber chopped yarns in the production process. At the same time, the invention also relates to a water coating method of the water coating system. Background technique [0002] The short-cut water coating system has undergone three improvement processes, from roller coating to conventional spray head water coating to conventional spray plus water vapor mixed coating water; roller coating adopts a large roller installed in the water tank, which is tumbling according to the motor speed , The yarn rubs through the upper end of the roller, and the water is coated at the moment of friction. This water coating mode is gradually replaced by the conventional spray head because of the large water flow rate, poor uniformity, inconvenient operation, and potential safety hazards. Although the conventional spray head is superior ...
