Description
Technical Field
The utility model relates to the field of textiles, in particular to a rapid cooling device for high-strength nylon 6 DTY.
Background
The existing nylon 6DTY preparation process needs a cooling plate. The existing cooling plate is generally a V-shaped metal plate with the length of 1-1.5 meters, and plays the following roles: 1. cooling the tow to provide sufficient rigidity to false twist; 2. the cooling and fixing function is performed on the curled structure of the false-twisted fiber.
In general, the conventional chinlon 6POY is used as a raw material, the temperature of an elastic heating box is 165-175 ℃, and the filament can be cooled to below 80 ℃ after coming out of the heating box through a cooling plate; when the high-strength chinlon 6FDY is used as the elasticizing raw material, the temperature of the hot box during elasticizing must be higher than that of the conventional POY due to the high orientation degree and the crystallinity, so that the molecular chain of the high-strength chinlon 6FDY has the movement capability, namely the tows have plasticity. The temperature of a hot box is 185-195 ℃ when the high-strength nylon 6FDY is subjected to texturing, the residual temperature of the tows after the tows come out of the hot box with the high temperature is higher, and if the tows are cooled by a common cooling plate, the temperature of the tows cannot reach below 80 ℃, so that false twisting cannot be normally performed.
The defects of the prior cooling plate are as follows: 1. the existing cooling plate can not enable the polyamide-6 at high temperature to be rapidly cooled to the required temperature (below 80 ℃); 2. the existing cooling plate can only play a role in cooling after being directly contacted with the tows, so that the abrasion of the cooling plate on the tows can be increased, and the quality problems of broken filaments, broken ends and the like of products are caused.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a rapid cooling device for high-strength nylon 6DTY, which can rapidly cool tows and simultaneously does not need to be in direct contact with the tows to cause the reduction of product quality.
The utility model is realized in the following way:
a rapid cooling device for a high-strength nylon-6 DTY comprises a strip-shaped hollow sleeve body, wherein a cavity for circulating chilled water is arranged in the sleeve body, and a circulating water inlet and outlet communicated with the cavity is arranged on the outer wall of the sleeve body; openings for the silk strips to come in and go out are formed in the two ends and the upper end of the sleeve body.
Furthermore, the sleeve body is of a hollow annular structure.
Further, the inner diameter of the sleeve body is 1.5-3 cm.
Further, the length of the sleeve body is 1.0-1.5 m.
Further, the thickness of the cavity is 0.7-1.2 cm.
Further, the width of the opening is 0.3-0.7 cm.
Furthermore, the circulating water inlet and outlet is arranged on one side of the outer wall of the sleeve body, and the circulating water outlet and outlet is arranged on the other side of the outer wall of the sleeve body and is respectively connected to the lowest end and the highest end of the outer wall.
Furthermore, the circulating water inlet and outlet is connected with the chilled water circulating system through a chilled water circulating pipeline.
Furthermore, wire guides are distributed at two ends of the sleeve body.
The utility model has the advantages that: the utility model designs the cooling device for high-strength nylon 6FDY texturing, which has higher cooling efficiency and lower cooling temperature, can effectively and rapidly cool the nylon 6 fiber at high temperature to the temperature (below 80 ℃) required by processing, so that the texturing process can be smoothly carried out, the production stability is ensured, the elasticity and the fluffiness of the high-strength nylon 6DTY are ensured, the generation of stiff yarns and hard end yarns is reduced, and the yield and the high-quality product rate of products are improved.
Drawings
The utility model will be further described with reference to the following examples with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to fig. 1, the rapid cooling device for high-strength nylon 6DTY of the present invention comprises a sheath body 1; the sleeve body 1 is formed by a hollow pipe fitting formed by combining two linear pipes with the cross sections of major arcs inside and outside, and the end parts of the two linear pipes are connected to ensure that two end surfaces of the hollow pipe fitting are both major arc structures with certain thickness; the structure of the major arc enables the cooling and heat dissipation of the strand silk to be more uniform, and the strand silk 100 is put into the hollow structure of the hollow pipe fitting through the gap 14 formed by the major arc in the process of threading; a cavity 11 is formed between the two linear tubes and used for circulating chilled water;
a water inlet 12 and a water outlet 13 are arranged on the outer linear pipe, the water inlet 12 and the water outlet 13 are respectively arranged at the lower end and the upper end of the outer linear pipe (the water inlet 12 and the water outlet 13 can be used alternately), and the water inlet 12 and the water outlet 13 are connected with a chilled water circulating system (the existing device) through a chilled water circulating pipeline; the chilled water circulation system enables the circulating water in the cavity to maintain a low temperature of 2-5 ℃, so that the temperature of the filament is rapidly reduced. The chilled water backwater enters the refrigerating unit through the circulating water pump to reduce the temperature of the chilled water to be chilled water, the chilled water is pressurized by the chilled water circulating pump and then conveyed into the cavity, and the chilled water comes out from the water outlet 13 after heat exchange and then returns to the refrigerating unit for recycling;
the two ends of the sleeve body 1 are distributed with the thread guides 2. The strand silk is led out from the first hot box and then is led by the yarn guide 2, enters the hollow structure through a gap 14 formed by the major arc on the sleeve body for cooling and cooling, so that the strand silk 100 is effectively cooled to be below 80 ℃, and is led by the other yarn guide 2 after being cooled. Two ends of the sleeve body are respectively provided with a yarn guide 2 so as to prevent the yarn bundle from directly contacting with the cooling plate and reduce the friction of the yarn bundle. The temperature sensor is arranged on the inner wall of the sleeve body, so that the temperature of the sleeve body is monitored, and the temperature of the strand silk is judged.
