Embodiment 1

[0074] Such as Figure 3-5 As shown, this embodiment provides a double-row synthetic tow cooling device, which includes a cooling box 100 , a housing 200 and an air supply device for sending cold air into the cooling box 100 . The cooling box 100 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 being connected, the upper part 101 and the lower part 102 are arranged in communication, so as to form the box structure of the cooling box 100 .

[0075] The upper cover plate 108 is provided with two rows of parallel and evenly staggered circular holes. The wire mesh cylinders 103 are respectively installed into the interior of the upper part 101 from the position of the above circular holes, and then enter the lower part 102. After the lower part 102 is described, it is sealed and fixed on the wire...

Embodiment 2

[0091] This embodiment provides a double-row synthetic tow cooling device, which is a modification based on Embodiment 1. 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, and the inclined inner wall 100 d is substantially parallel to the straight line, and the inclined inner wall 100 d intersects the perforated plate 201 at the hypotenuse 107 . Wherein, th...

Embodiment 3

[0093] 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 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. The multi-row synthetic tow cooling device comprises a cooling box and an air supply device used for supplying cold air into the cooling box. A plurality of rows of air duct assemblies for tows to pass through are arranged on the cooling box, a perforated plate is arranged between the cooling box and the air supply device, and a plurality of vent holes are formed in the perforated plate. Cold air from the air supply device enters the exteriors of silk screen cylinders in the air duct assemblies through the vent holes and enters the interiors of the silk screen cylinders through the outer circumferences of the silk screen cylinders. Circulation space is formed in the outer circumferences of the silk screen cylinders, and the adjacent silk screen cylinders in the same row, the adjacent silk screen cylinders in different rows and different inner walls of the cooling box are communicated through the circulation space. By controlling the amount of the cold air entering different positions in the circulation space, the differential values between air pressures of the cold air at different positions in the circulation space and air pressures inside the silk screen cylinders are basically consistent.

Description

technical field [0001] The invention relates to a cooling device for multi-row synthetic tow, 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 uniform and stable external cooling conditions (mainly controlling the uniform and stable wind speed) is very important for spinning high-quality filaments. [0003] Chinese patent document CN201377007Y discloses a cooling device for cooli...
