Description

Technical Field

[0001] The utility model relates to the technical field of nylon 6 industrial yarn production, in particular to a nylon 6 industrial yarn hot drawing roller. Background Art

[0002] Nylon 6 industrial yarn, whose full name is polycaprolactam fiber industrial yarn, is an industrial fiber material made of caprolactam polymerization. The hot drawing roller is one of the key equipment in the production process of nylon 6 industrial yarn. It is mainly used for hot drawing treatment of nylon 6 filaments to improve the orientation, strength and toughness of the filaments.

[0003] The existing hot stretching roller is mainly composed of a roller body, a heating system, a transmission system and a control system. In the production process of nylon 6 industrial yarn, the filament is sent into the hot stretching roller area after melt spinning. At this time, the roller body has been heated to the set temperature and driven to rotate through the transmission system. The filament is subjected to the high temperature and stretching force on the roller body, and the molecular chain is oriented and rearranged, thereby improving the orientation degree and strength of the filament.

[0004] Since nylon 6 industrial yarns of different batches or for different purposes may require different drawing conditions and roller diameters to achieve the best drawing effect, the roller diameter of the existing hot drawing roller is often fixed, which is difficult to meet the requirements of different fiber properties, and may lead to unsatisfactory drawing effect or damage to fiber performance, thereby affecting the quality of the product, and the overall heat dissipation effect is poor, resulting in large loss during use; therefore, a nylon 6 industrial yarn hot drawing roller is proposed to address the above problems. Utility Model Content

There is a curved roller plate, and one end of the bidirectional screw rod away from the driving shaft is fixedly connected with a rotating cap, and the bidirectional screw rod and the driving shaft are coaxially arranged. When the diameter of the hot stretching roller is adjusted according to demand, the rotating cap is rotated to rotate the bidirectional screw rod, and with the cooperation of the limiting slide groove, the two circular movable plates are moved closer to or away from each other, and then the swing rod drives the curved roller plate to expand or contract, so that the diameter and tensile strength of the hot stretching roller can be flexibly adjusted according to different fiber types and their characteristics to meet the needs of different fiber types and characteristics, so as to achieve the best stretching effect and avoid the phenomenon of unsatisfactory stretching effect or damaged fiber performance, thereby improving the quality of the product, and can improve the overall heat dissipation effect and reduce energy consumption.

[0007] Preferably, each fixing plate is provided with a screw hole, and a locking bolt is rotatably assembled in each screw hole, and the end of the locking bolt is in contact with the outer surface of the curved roller plate.

During the hot drawing process, when the driving shaft and the cavity roller body are on the same axis, with the cooperation of the counterweight ball, the fixing rod will maintain a relatively straight state, and the detection plate will not move significantly. When the driving shaft and the cavity roller body are not on the same axis, the fixing rod will swing, and with the cooperation of the spring, the detection plate will move up and down reciprocatingly. By setting up a detection mechanism, it is possible to make an accurate judgment on whether the driving shaft and the cavity roller body are coaxial. When the two are not coaxial, timely adjustment is required to ensure that the driving shaft and the cavity roller body are coaxially arranged, thereby ensuring that the wire is evenly stressed, the forming effect is good, and the drawing roller movement is stable and the wear is small.

[0009] Preferably, the detection board is equipped with two fluorescent plates, and the two fluorescent plates are respectively located on both sides of the fixing rod. When the device is used, by setting the fluorescent plates, sufficient light is provided in a dark environment, making it easy to observe whether the detection board moves.

[0025] Working principle: Since different batches or different uses of nylon 6 industrial yarns may require different stretching conditions and roller diameters to achieve the best stretching effect, the roller diameter of the existing hot stretching roller is often fixed, which is difficult to meet the needs of different fiber characteristics, and may lead to unsatisfactory stretching effects or damage to fiber performance, thereby affecting the quality of the product, and the overall heat dissipation effect is poor, and the use loss is large; therefore, in view of the above problems, a nylon 6 industrial yarn hot stretching roller is proposed; when the diameter of the hot stretching roller is adjusted according to demand, the rotating cap 12 is rotated to rotate the bidirectional screw rod 4, and with the cooperation of the limiting slide groove 3, the two circular movable plates 5 are moved closer to or away from each other, and then the swing rod 7 drives the curved roller plate 10 to expand or contract, so that the diameter and tensile strength of the hot stretching roller can be flexibly adjusted according to different fiber types and their characteristics to meet the needs of different fiber types and characteristics.
