Smelting nozzle structure for chemical resin

Abstract

The invention relates to a smelting nozzle structure for chemical resin. The smelting nozzle structure comprises a support, wherein the support is fixedly connected with a cylinder and a heating block; the heating block is connected with a guide tube; the guide tube is connected with a capillary tube; air flow distribution devices are fixedly connected to the lower part of the heating block through a bracket plate; an air flow inlet and a guide channel are formed in each air flow distribution device; a first inclined tube and a second inclined tube which are communicated with the guide channels are fixedly connected between the guide channels and the bracket plate; a first through hole and a second through hole are formed in the center of the bracket plate; the heating block is provided with first baffles in symmetry; first arc-shaped guide plates are arranged at the lower ends of the first baffles; the lower ends of the first arc-shaped guide plates extend into the second through holes; a plurality of first guide holes are formed in the first arc-shaped guide plates in the first through holes and the second through holes; second baffles are symmetrically arranged on the first bracket plate; second arc-shaped guide plates are arranged at the lower ends of the second baffles; second guide holes are formed in the second arc-shaped guide plates; the second guide holes tilt towards the lower end of the capillary tube.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a resin melt blown machine. Background technique [0002] The meltblown machine is a one-step cloth-forming equipment that uses the meltblown method to make resin slices or resin particles into fiber webs. The fiber webs are generally used for filter materials, oil-absorbing materials, sanitary materials, etc. The meltblown die head is a key component of the meltblown machine, and the uniformity of the meltblown nonwoven fabric is closely related to the design and manufacture of the die head. The structure of the existing melt-blown die head is relatively complicated, the cost is high, and the melt-blown head adopts a stretching action on the polymer melt, resulting in an uneven processed fiber web and low product quality. At present, there has been a melt-blown die head for secondary stretching of the resin, which avoids the defect of primary stretching, but there is still a s...

Problems solved by technology

The structure of the existing melt-blown die head is relatively complex, the cost is high, and the melt-blown head adopts a stretching action on the polymer melt, resulting in the processed fiber web not being uniform enough and the quality of the product is low

At present, there has been a melt-blown die head for secondary stretching of the resin, which avoids the defect of primary stretching, but there is still a shortcoming that the resin fuse is stretched by using the upper and lower direct injection method, and the fuse is easy to be drawn by both sides. Uneven spraying and uneven thickness, long-lasting spraying is required, and its quality and efficiency need to be improved
