[0038] Such as figure 1As shown, the existing production process of centrifugal spinning equipment can be summarized as long and short fibers required by the fiber production assembly 1 to generate non-woven fabrics, which are collected through the belt-shaped collection assembly 4 to form a centrifugal spinning fiber web 7 and slowly move forward, and then passed through the bonding assembly 5 The centrifugally spun web 7 is bonded into a felt and wound by the bobbin assembly 6 to obtain a finished non-woven fabric.
[0039] Such as figure 2 As shown, the fiber production component 1 can be simply summarized as a bracket 11, a rotating motor 12, a liquid inlet pipe 13, and a liquid outlet pipe 14; the bracket 11 is a double-degree-of-freedom bracket, which can move freely along the vertical direction and the vertical direction of the conveyor belt. There are two fiber production units symmetrically distributed on the left and right sides to form a fiber production unit; eac...

The invention discloses a centrifugal spinning negative-pressure traction device. The centrifugal spinning negative-pressure traction device comprises porous partition plates, a negative-pressure generating device and a funnel cavity, wherein the negative-pressure generating device is connected with the funnel cavity to provide negative-pressure suction force for a large-area fiber collecting plate, and the traction adsorption forces of provided negative pressure to various portions of the fiber collecting plate are evenly distributed through a plurality of layers of porous partition plates with gradually changed pore diameters. On the one hand, through the simple structure, secondary traction of negative pressure on the fibers is utilized, so that the fiber solidification forming speed and the fiber falling speed are increased, fiber thickness and distribution are uniform, and the efficiency of the production process is high; and on the other hand, the fibers are guided to collect andabsorb impurities such as excessive volatile solvents and boundary-crossing fibers through the traction effect of the negative pressure, so that the production safety and the quality of finished products are improved.
Description
technical field [0001] The invention relates to the field of nonwoven fabric production, in particular to a centrifugal spinning negative pressure traction device. Background technique [0002] Non-woven fabrics or non-woven fabrics and non-woven fabrics, which directly use polymer chips, short fibers or filaments to form fibers through airflow or mechanically, and then undergo hydroentanglement, needle punching, or hot rolling reinforcement, and finally Compared with traditional woven fabrics, the non-woven fabrics formed after finishing have broken through the traditional textile principles. Antibacterial, environmental protection and other advantages, widely used in people's daily life. [0003] Compared with the traditional textile industry, the production of non-woven fabrics, an emerging industry, has also been greatly developed. At the same time, as the demand for non-woven fabrics increases, there are more and more preparation technologies, and centrifugal spinning ...
