A polymer monofilament liquid applying (oil applying, functional sizing agent applying and wrapping) device

Abstract

The invention provides a polymer monofilament liquid applying (oil applying, functional sizing agent applying and wrapping) device. The device mainly comprises a liquid applying and filament guide channel assembly 1, a liquid applying and filament guide channel assembly drive device 2, a liquid storage assembly 3, a liquid quantitative conveying assembly 4 and an overflow assembly 5. A liquid applying and filament guide assembly channel can be in the shape of a flat surface or a curved surface; the carrier thereof can be roller-shaped or wheel-shaped and is fixed on a liquid applying and filament guide member base. The drive device 2 is connected to one end of the liquid applying and filament guide channel assembly. The liquid applying and filament guide channel assembly is characterized in that a liquid applying surface is provided with liquid guide grooves of different shapes and specifications. The device is simple in structure; the liquid applying surface processing precision and fineness are high, and damage to polymer monofilaments can be reduced; the liquid applying uniformity in the radial direction and the axial direction of the monofilaments can be guaranteed and the liquid applying efficiency is increased; the device can fulfill the functions of a filament guide device and a filament separating device and can be used for the liquid applying (oil applying, functional sizing agent applying and wrapping) of various kinds of polymer monofilament materials.

Description

technical field [0001] The invention discloses a polymer monofilament coating (oiling, functional slurry and coating) device, which belongs to the equipment for uniform coating (oiling, sizing and functional liquid coating) in the process of polymer polymerization and device field. technical background [0002] The melt spinning process of polymer monofilament mainly includes chip conveying-crystallization drying-melt spinning-water bath cooling-drying-drawing-heat treatment-oiling winding-inspection and storage. Oiling of polymer monofilaments is an important step in the production process. At present, the oiling devices used in the melt spinning process of polymer monofilaments are mainly divided into two types: non-porous and porous. The non-porous oiling roller, such as patent 95108006.7, replaces traditional pottery with magnesium oxide and magnesium chloride as a binding agent. The oiling of this oiling roller is uneven and the oiling performance is poor. [0003] Pa...

Problems solved by technology

The non-porous oiling roller, such as patent 95108006.7, uses magnesium oxide and magnesium chloride instead of traditional ceramics as a binder. The oiling of this oiling roller is uneven and the oiling performance is poor

[0003] Patents 200320127174.1 and 200310116626.0 provide an oiler and roller with a metal substrate. Although the metal substrate has micropores, the metal substrate is too heavy, which increases the driving load; and the micropores of the metal substrate are too small, which seriously affects oiling. effect, resulting in reduced oiling performance

Patent 200720129082.5 discloses a microporous oiling roller and wheel with an oil storage tank, but the oiling roller with micropores is easy to block, which reduces the oiling effect; during the oiling process, the monofilaments tend to stick together , the dispersion effect is poor, which is not conducive to the subsequent winding process; the above designs are all plane oiling devices, the monofilament oiling angle is small, the oiling uniformity is poor, and the oiling rate is low; moreover, the design of this oiling roller and wheel is complicated , difficult to process, high production cost
