The working principle is as follows: when the melt-blown fiber production mechanism is used, molten polypropylene raw materials are ejected in a filiform manner through the melt-blown machine body 3, meanwhile, the belt pulley I4 and the winding roller 2 are driven to synchronously rotate through the transmission shaft 7 under the action of the transmission part, so that the belt 6 is continuously transmitted, when the surface of the belt 6 passes right below the melt-blown machine body 3, the melt-blown fibers fall on the belt 6, the melt-blown fabric 26 is formed along with the continuous movement of the belt 6, then the melt-blown fabric 26 can be automatically and continuously wound under the rotation of the winding roller 2, and the automation degree is higher;

in the production process, once the spinning speed of the upper discharge hole of the melt-blown machine body 3 is increased, under the condition of not changing the spinning distance, high-speed spinning can generate higher-intensity pressing on the upper part of the belt 6, then the spinning pressing intensity is sensed by the monitoring part, the sensed pressure value is changed into an electric signal and transmitted to the telescopic driving part, the telescopic driving part reasonably controls the melt-blown machine body 3 to be lifted relative to the belt 6 according to the signal, so that the blanking distance of the spinning is adjusted, the final blanking speed is changed, and the problems that manual adjustment of the spacing of the spinning blanking is time-consuming and labor-consuming and the efficiency is lower due to the change of the spinning speed of a melt are solved;

in the process of lifting the melt-blown machine body 3, the rack plate 10 is synchronously driven to lift through the connecting arm 11, the friction driving wheel 15 is driven to rotate clockwise by taking the transmission shaft 7 as the center of a circle through the lifting of the rack plate 10 and the meshing relation between the rack plate 10 and the gear 9 and the fixed relation between the supporting plate 12 and the gear 9, the center of the circle where the arc of the side edge of the conical friction wheel 8 is positioned is concentric with the transmission shaft 7, and then the circle can be always contacted with the side edge of the conical friction wheel 8 in the rotating process of the friction driving wheel 15, so as to ensure the transmission between the conical friction driving wheel and the conical friction wheel 8 to be carried out, when the friction driving wheel 15 rotates clockwise, the transmission ratio between the friction driving wheel 15 and the conical friction wheel 8 is gradually increased, and then when the rotating speed of the motor 5 is not changed, the rotating speed of the transmission shaft 7 is gradually reduced through the transmission of the conical friction driving wheel 8, the friction driving wheel 15, the connecting shaft 13 and the two conical gears 14, therefore, considering that the high-speed spinning is relatively short in moving down time of the low-speed spinning in the air, and the carried heat is less lost in high-speed contact with the air, after the rotating speed of the transmission shaft 7 is reduced, the rotating speeds of the first belt pulley 4 and the winding roller 2 are reduced, and at the moment, the winding and receiving speed of the winding roller 2 on the melt-blown fabric 26 is reduced, so that the contact time of the melt-blown fabric 26 and the air can be prolonged, the carried heat is transferred to the air, and the heat accumulation when the melt-blown fabric is wound by the winding roller 2 is avoided, and the influence on the quality of a product is caused;

the conical friction wheel 8 rotates, the connecting rod 16 drives the induced fan 18 to synchronously rotate, and then the air is blown to the conical friction wheel 8 direction through the rotation of the induced fan 18, so that on one hand, the heat generated at the friction contact part between the conical friction wheel 8 and the friction driving wheel can be quickly taken away under the action of flowing wind force, on the other hand, the redundant hot air can be absorbed through the induced wind port I20 and the induced wind port II 21 on the induced air cover 19, and simultaneously, the flow of normal temperature air above the belt 6 can be accelerated, and the fiber bundle can be better cooled;

when the rotating speed of the transmission shaft 7 is changed, the rotating speed of the motor 5 can be kept unchanged, and further the induced air strength of the induced air fan 18 can not be changed, so that the induced air strength can be kept in a proper range all the time, and the phenomenon that when the induced air strength is too high, the fiber bundles sprayed by the melt-blown machine body 3 are sucked, the fiber bundles are irregular, and the forming of the melt-blown cloth 26 is influenced is avoided.
