Problems solved by technology

[0005] The above-mentioned melt-blown die head has the following defects: the die body of the above-mentioned melt-blown die head is fixedly connected to the air plate and the spinneret, so that the size of the gap formed between the air plate and the spinneret is also fixed. Yes, but in the process of actual parts production, there will be dimensional tolerances between the air plate and the spinneret itself, so that the two gaps formed after the die head is assembled will have different sizes, resulting in the ejected airflow The size is different, which affects the uniformity of the die spraying

Embodiment 1

[0033] see figure 1 and figure 2 , the embodiment of the application discloses a melt-blown die head with a hot runner system, which includes a long strip-shaped main body mold 2, and a connecting pipe 17 is connected to the middle position of the upper end surface of the main body mold 2; the main body mold 2 includes a mold body 21, a set Diverter plate 24 and several hot nozzles 25 in mold body 21, divider plate 24 is provided with the buffer channel 26 that communicates with connecting pipe 17, buffers, and buffer channel 26 includes two horizontal flow channels 261 extending horizontally up and down. and the arc-shaped flow channel 262 that communicates with two transverse flow channels 261, the hot nozzles 25 are all located under the splitter plate 24, and each hot nozzle 25 is connected to the buffer flow channel 26, and the raw materials entering from the connecting pipe 17 will be Pass through the buffer channel 26 of the splitter plate 24 and continuously split in...

Embodiment 2

[0041] see Figure 4 The difference between this embodiment and Embodiment 1 is that the fixing screw 11 is fixedly connected to the mold body 21 after passing through the second through hole 12. When disassembling and cleaning the crevice channel 5, it is necessary to unscrew the fixing screw 11 and the mold body 21 respectively. Bolt 13.

Abstract

The invention relates to a melt-blowing die head with a hot runner system, and belongs to the field of die equipment. A spinneret orifice is formed in the bottom part of a main die; two air plates aremutually symmetrical with respect to the axis of the spinneret orifice; gap channels are respectively formed between the two air plates and the main die; air inlets of the two gap channels are in butt joint and communication with airflow channels; air outlets of the two gap channels face the discharging direction of the spinneret orifice; the main die is provided with an installation groove for installing the air plates; the length, opposite to the connection direction of the two air plates, of the installation groove is larger than the length of each air plate; the air plates are fixed to the main die through adjusting screws and locking screws; the main die is provided with threaded holes adaptive to the adjusting screws; the screw-thread sections of the adjusting screws are arranged inthe threaded holes; the inner ends of the adjusting screws are abutted against the side walls of one sides, far away from the spinneret orifice, of the air plates; the main die is provided with firstthrough holes; and the screw-thread sections of the locking screws penetrate through the first through holes and are in threaded connection with the side walls of one sides, far away from the spinneret orifice, of the air plates. The melt-blowing die head can spray silks uniformly.

Description

technical field [0001] The present application relates to the technical field of mold equipment, in particular to a melt blown die head with a hot runner system. Background technique [0002] Meltblown method is a commonly used textile method in non-woven fabric production technology. Generally, high-speed hot air flow in cross direction is used to draw and solidify the high polymer extruded from the mold hole. It is often used to produce polypropylene, polyester, etc. Nonwovens. [0003] The melt blown machine is the core component of the non-woven fabric produced by the melt blown method, and the melt blown die head is the core component of the high polymer wire drawing in the melt blown machine. The design of the melt blown die head directly affects the length and uniformity of the wire drawing. properties, toughness, fineness and many other aspects, which have a decisive impact on the final cloth product. [0004] The Chinese patent with the application number: 2018105...
