Water coating device and water coating method in fiber chopping process

Abstract

The invention provides a water coating device in a fiber chopping process. The water coating device comprises a water coating roller and a drive device of the water coating roller. The water coating device is characterized by further comprising a tension rod, wherein the tension rod is close to the water coating roller and parallel to the water coating roller; and yarns are enabled to firstly pass through the upper cutting surface of the water coating roller and then pass through the upper cutting surface of the tension rod during the chopping process by virtue of the installation position of the tension rod, i.e., the tension rod is arranged in front of the water coating roller through which the yarns pass. The water coating device is used for solving the problem that the yarns are easily wound on the water coating roller during the chopping process, and used for improving the production efficiency and reducing the rejection rate; and moreover, the water coating device is low in cost, simple and convenient to operate and capable of greatly improving the production efficiency without changing the original production process. The invention further discloses a water coating method in the fiber chopping process.

Description

technical field [0001] The invention relates to a water coating device and a water coating method in the fiber chopping process, in particular to a water coating device and a water coating method that do not involve yarns. Background technique [0002] At present, in the chopping process of glass fiber or other fibers, usually the yarn cake yarn 1 passes through the yarn threading plate hole of the front threading plate 2, and passes through the water application roller 3 of the water application device (the effect of the water application roller 3 After the yarn 1 is coated with water), it is directly fed into the chopping machine 7 through the yarn threading plate 6 and chopped, such as Figure 1a shown. This water applicator has the following disadvantages: when the rotation frequency of the water applicator 3 is opened to a relatively high frequency (such as 20Hz), the yarn 1 is easily entangled in the water applicator 3 (such as Figure 1b Involved in the direction sho...
