An antistatic agent coating device

Abstract

The invention discloses an antistatic agent coating device, comprising a high liquid storage tank and a low liquid storage tank for storing the antistatic agent, the high liquid storage tank is provided with a first opening, and the low liquid storage tank is provided with a The first opening communicates with the second opening through the first connecting pipe. The first opening is higher than the second opening so that the antistatic agent in the high-level liquid storage tank flows into the low-level liquid storage tank. A float valve with opening and closing, so that the liquid level in the low-level liquid storage tank is maintained at the first position, and also includes a second connecting pipe and an oiling tank located below the first position for applying antistatic agent, and the second connecting pipe One end of the second connecting pipe is located in the low-level liquid storage tank and lower than the first position, the other end is connected to the oiling groove, and the bottom of the highest point of the second connecting pipe is located above the first position. Use the principle of siphon to evenly transport the antistatic agent to the oiling tank to ensure that the oiling tank will evenly spread the antistatic agent on the glass fiber.

Description

technical field [0001] The invention relates to the technical field of antistatic agent coating, and more specifically, relates to an antistatic agent coating device. Background technique [0002] In the process of glass fiber production, especially in the production of ply yarn roving, it is usually necessary to apply a certain amount of antistatic agent on the surface of glass fiber to avoid the harm caused by static electricity on the surface of glass fiber in the subsequent use of customers. Such as fiber electrostatic adhesion knife stick, poor dispersion and other problems. [0003] Since the flow rate required for coating the antistatic agent on the glass fiber is small, generally 0.5-4ml / min, in order to ensure the controllability of the flow rate of the antistatic agent coated on the surface of the glass fiber, a peristaltic pump is used in the existing solution The electrostatic agent is delivered quantitatively. However, since the principle of peristaltic pump de...

[0003] Since the flow rate required for coating the antistatic agent on the glass fiber is small, generally 0.5-4ml / min, in order to ensure the controllability of the flow rate of the antistatic agent coated on the surface of the glass fiber, a peristaltic pump is used in the existing solution The electrostatic agent is delivered quantitatively. However, since the principle of peristaltic pump delivery is to use the motor to drive the steel ball to rotate, and periodically squeeze the outer wall of the latex hose to transport the fluid, the flow rate of the antistatic agent presents an obvious pulse phenomenon, which causes the surface of the glass fiber to be coated with an antistatic dose. Inhomogeneity affects the antistatic effect of fibers
