Embodiment 1

[0054] This embodiment provides a double-row synthetic tow cooling device, such as Figure 3-4 As shown, the double-row synthetic tow cooling device includes a cooling box 100, a housing 200, and a porous plate 201 with a plurality of ventilation holes 111 arranged between the cooling box 100 and the housing 200, wherein the cooling box 100 It includes an upper part 101 and a lower part 102. The upper part 101 includes an upper cover plate 108 and a seal. The lower part 102 is a hollow box structure, and its upper part is connected to the upper part 101 through a seal. After the connection, the The upper part 101 and the lower part 102 are communicated to form a box structure of the cooling box 100 .

[0055] The upper cover plate 108 is provided with two rows of parallel and evenly staggered circular through holes, and the wire mesh cylinders 103 are respectively installed into the interior of the upper part 101 from the position of the above circular through holes, and then en...

Embodiment 2

[0077] The present embodiment provides a double-row synthetic tow cooling device, which is a deformation based on Embodiment 1, such as Figure 9 and Figure 10 As shown, in this embodiment, the wall structure of the cooling box 100 is different from that of Embodiment 1, specifically, the cooling box 100 is a housing, and the housing includes a horizontal inner wall 100c and a horizontal inner wall 100c connected to at least one inclined inner wall 100d, multiple rows of the wire mesh cylinders 103 are respectively arranged parallel to the horizontal inner wall 100c, the adjacent rows of the wire mesh cylinders 103 are arranged in a staggered manner, different rows close to the inclined inner wall 100d A line connecting the centers of a plurality of adjacent wire mesh cylinders 103 forms a straight line, the inclined inner wall 100d is arranged parallel to the straight line, and the inclined inner wall 100d intersects the perforated plate 201 at the hypotenuse 107 . Wherein,...

Embodiment 3

[0080] This embodiment provides a double-row synthetic tow cooling device, which is a modification of Embodiment 1. In this example, if Figure 11 As shown, the means of reducing the amount of cold air entering the first circulation space A through the ventilation holes 111 per unit time is different from that of Embodiment 1. In this embodiment, by changing the perforated plate 201 The arrangement of the ventilation holes 111 is to change the amount of cold air entering the first circulation space A, specifically, the density of the ventilation holes 111 on the perforated plate 201 opposite to the first circulation space A The density of the ventilation holes 111 on the perforated plate 201 opposite to the other circulation spaces B is lower than that of the ventilation holes 111 in the first circulation space A, so that the amount of cold air in the first circulation space A is different from the amount of cool air in the other circulation spaces B. Basically the same.

Abstract

The invention provides a multi-row synthetic tow cooling device, which includes a cooling box, a perforated plate and a housing connected under the perforated plate. Multiple rows of wire mesh cylinders are arranged on the cooling box for the tow to pass through. A perforated plate is set between the air devices, and several ventilation holes are set on the perforated plate. The cold air from the air supply device enters the outside of the wire mesh cylinder through the ventilation holes, and enters the wire mesh cylinder through the outer circumference of the wire mesh cylinder. Inside, the fine flow of polymer melt that enters the inside of the screen cylinder and is sprayed out by the spinneret is cooled into filaments, and a circulation space is formed on the outer circumference of the screen cylinder, and the circulation space communicates with adjacent screens in the same row cylinder, different rows of adjacent wire mesh cylinders, and different inner walls of the cooling box, by controlling the amount of cold air entering different positions in the circulation space, the wind pressure of the cold air at different positions in the circulation space is the same as that inside the wire mesh cylinder The difference in wind pressure is basically the same.

Description

technical field [0001] The invention relates to a multi-row synthetic tow cooling device, which belongs to the technical field of synthetic tow cooling. Background technique [0002] When producing synthetic filaments, the thin stream of polymer melt ejected from the micropores of the spinneret is forced to cool in the cooling device by blowing cold air, and condenses and solidifies into filaments in a short time. The wind pressure and wind speed of the cold air in the cooling device have a great influence on the uniformity of the filaments formed after the polymer melt fine stream condenses and solidifies. The above-mentioned uniformity mainly refers to the diameter, strength, elongation, etc. of the filament. Therefore, maintaining the uniformity and stability of the external cooling conditions (mainly controlling the uniformity and stability of the wind speed) is very important for spinning high-quality filaments.
