Description

TECHNICAL FIELD

[0001] The utility model relates to a polyamide production equipment technical field especially relates to a polyamide 6 winding oiling system tension adjusting device. BACKGROUND

[0002] The conventional spinning oiling usually cannot reach the cooling state when producing the single fiber thicker product. This is because the single fiber is thicker, and the specific surface area is relatively small. Under the same cooling condition, the heat is dissipated slowly, which leads to that the fiber cannot be cooled sufficiently in the conventional spinning oiling process. The insufficient cooling of the fiber will bring many problems, such as the unstable physical properties of the fiber, which affects the subsequent processing and product quality; and it can also lead to the uneven adhesion of the oil agent on the fiber surface, which reduces the oiling effect.

[0003] Therefore, it is necessary to prolong the cooling distance, so that the fiber has more time and space to dissipate heat, and a better cooling state is achieved. For this purpose, when producing the single fiber thicker product, the conventional oiling method is changed to winding oiling. The winding oiling is an oiling operation before the winding process. The advantage of this is that the single fiber thicker polyamide product has sufficient cooling distance and cooling time. The surface temperature of the fiber that has been sufficiently cooled is lower, and the oil agent can be better adhered to the fiber surface, which improves the uniformity and stability of the oiling; and it can also avoid the volatilization or decomposition of the oil agent due to the high temperature of the fiber surface when the fiber is oiled without being sufficiently cooled, which affects the oiling effect and the fiber properties.

[0004] However, the existing winding oiling device has some problems in actual use. Due to the low friction coefficient and small tension, part of the tow is concentrated and clumped before entering the oil nozzle. This is because the low friction coefficient makes the interaction force between the tows small, which is difficult to maintain the dispersed state, thereby leading to the aggregation of the tows before entering the oil nozzle. This concentrated clumping phenomenon will lead to uneven or insufficient oiling of the tows. The fibers on the outside of the tow can contact more oil agent, and the oiling is sufficient, but the fibers on the inside may be wrapped by the outside fibers and cannot fully contact the oil agent, thereby leading to uneven oiling; at the same time, due to the insufficient oiling of part of the fibers, the overall oiling will also be insufficient, which affects the dyeing effect of the tow. TECHNICAL PROBLEM

[0005] The technical problem to be solved by the utility model is to provide a polyamide 6 winding oiling system tension adjusting device, which can improve the tension of the winding oiling system, prevent the tows from being concentrated and clumped before entering the oil nozzle, and improve the uniformity of the tow oiling.
