The invention discloses a controllable vibration electrostatic spinning device and belongs to the field of electrostatic spinning. The controllable vibration electrostatic spinning device mainly comprises a feed motor, a heating device, a feed cylinder, a sprayer, a receiving device, a high-voltage electrostatic generator, a screw, a temperature sensor, piezoelectric chip transducers and the like. The feed cylinder is connected with the feed cylinder through bolts. The upper end of the screw is connected with the feed motor through a coupler. The lower end of the screw is disposed in the cavity of the feed cylinder. A gap controlling body is mounted at the lower end of the screw. The sprayer is mounted on the rotary rail of the feed cylinder through mounting nuts and the studs on the upper side of the sprayer. A stepping motor allows the sprayer to rotate around a central shaft through gear transmission. A square groove is formed in the upper side of the sprayer and used for mounting the piezoelectric chip transducers. Each piezoelectric chip transducer is sequentially connected with a frequency converter, a power amplifier and a pulse signal source. The high-voltage electrostatic generator is connected with the receiving device. The temperature sensor is connected with a temperature control cabinet. The controllable vibration electrostatic spinning device has the advantages that the controllable ultrasonic waves generated by the piezoelectric chip transducers are used to act on spinning, melt spinning efficiency is increased, fiber diameter is lowered, the speed of the rotary sprayer is controllable, and uniformity of spinning fiber is increased.
Description
technical field [0001] A controllable vibration electrostatic spinning device belongs to the field of electrostatic spinning. Background technique [0002] Vibration is a common phenomenon in nature. In many cases, vibration is harmful. It will affect the working performance and service life of machinery and equipment, generate noise and dynamic load, and may cause accidents in severe cases. However, in some cases, the principle of vibration can be used to accomplish a lot of work. For example, the application of vibration technology in construction machinery is very common, such as soil compaction, pile sinking and pulling out, concrete tamping and molding, etc., and ultrasonic cleaning machines in the cleaning field. When vibrating, the relative movement between the pellets or between the pellets and other materials increases, and the internal friction of the materials decreases significantly. At this time, the material has a liquid-like property, which is generally cal...
