Problems solved by technology
In order to overcome the defects of low lifting precision, short life and high cost in the prior art, the utility model provides a double-row outer ring blowing tow cooling device, which includes an air duct, an air inlet box, and a ring blowing box. The air duct is connected with the horizontal air inlet box, and the air duct is provided with filter drawers and the first layer of perforated plates in sequence from bottom to top; the surrounding air box is arranged above the air inlet box, and a horizontal porous plate is arranged between the air inlet box; There are a number of guide tube seats in the air inlet box, and the same number of wind direction rectifiers as the guide tube seats in the ring blower box. The guide tube seats are connected with the wind direction rectifiers in a double-row staggered arrangement
The air duct in this utility model is more complicated and the cost is higher

The invention provides an airflow type strand pre-extraction device. The airflow type strand pre-extraction device is provided with a first strand guiding ring, an extractor and a second strand guiding ring. The extractor is composed of a bottom plate and a cover plate. One side of the cover plate and one side of the bottom plate are hinged together through a hinge, and the other side of the cover plate and the other side of the bottom plate can be opened and connected through attraction force of a magnet buried in the bottom plate. The bottom plate is provided with a strand passing cavity and an air blowing groove. The strand passing cavity is located in the center position of the bottom plate, and the air blowing groove is located at an inlet of the strand passing cavity and is perpendicular to the strand passing cavity. The front section, in the strand walking direction, of the cavity wall of the strand passing cavity has inclination, and therefore the thickness of the position of the inlet is larger than that of the position of an outlet. According to the airflow type strand pre-extraction device, the strand advancing friction is small, the damage to a strand is small, the strand walking power is provided, and the environment pollution is reduced.
Description
technical field [0001] The invention relates to a tow extraction or guiding restraint device produced or used in the chemical fiber or tobacco industry. Background technique [0002] During production or use, tows of natural or synthetic fibers usually rely on godet rolls, godet wheels, godet rings or godet plates to determine and control their position or direction. [0003] The utility model with the application number 2011205490992 discloses a guide ring structure and a tow guide device of a forming machine, and relates to the technical field of cigarette manufacturing. The invention solves the technical problem in the prior art that the tow swings are relatively large in the process of extracting the tow, which leads to unsatisfactory effects of stretching and opening of the tow. The guide ring structure includes a first annular body, a connecting body fixedly connected to the first annular body, and at least one second annular body fixedly connected to the connecting b...
