Abstract

The invention relates to the technical field of non-woven fabric production equipment, and discloses production equipment for electrostatic stretching high-pressure melt-blown non-woven fabrics, the production equipment comprises a melt-blown clamping plate, a spray head, an adjusting mechanism and an anti-blocking mechanism, the spray head is movably connected in the melt-blown clamping plate, the adjusting mechanism is arranged on the outer side of the melt-blown clamping plate, and the anti-blocking mechanism is arranged in the melt-blown clamping plate. The anti-blocking mechanism is fixedly connected to the interior of the right end of the spray head, a material injection pipe is movably connected to the interior of the left side of the spray head, and a fan is fixedly connected to the top end of the side, close to the material injection pipe, of the melt-blowing clamping plate. The air outlet speed of the fan can be changed while the receiving distance is changed through the adjusting mechanism, so that the bulkiness of a melt-blown fiber web and the bonding degree between fibers can be increased, and the quality of a non-woven fabric product is improved; and when the spray head is blocked by the polymer particles which are not completely molten, the polymer particles are reheated in time through the anti-blocking mechanism, and the heated and molten polymer is blown out by hot air flow, so that the effect of preventing the spray head from being blocked is achieved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production equipment, in particular to production equipment and methods for electrostatically stretching high-pressure melt-blown non-woven fabrics. Background technique [0002] Melt-blown non-woven fabrics are different from traditional non-woven spunbond methods. The melt-blown method uses high-speed hot air to stretch the polymer ejected from the spinneret hole of the mold, so that the molten polymer is stretched. It becomes a kind of ultra-fine short fiber, and then it will be sprayed onto the receiving roller by the nozzle, and the setting effect can be achieved through its own bonding force. [0003] When the existing high-pressure melt-blown non-woven fabric production equipment processes non-woven fabrics, when the receiving distance decreases or increases, the speed and temperature of the hot air flow will not change accordingly, so it will affect the melt-blown fiber web. The ...
