AI Technical Summary

Problems solved by technology

However, in the existing melt-blown cloth production line, the pressure of the molten material is unstable, resulting in poor quality of the produced melt-blown cloth, which cannot reach the 95 standard, and in the existing melt-blown cloth production line, the screw in the extruder needs Withstand large axial force, reducing the service life of the screw
In addition, the existing melt-blown cloth production line has a low degree of automation, requires multiple people to operate at the same time and the operation is complicated, the production labor cost is high, and the production efficiency is low.

[0046] The extruder 1 is used to insert raw materials and extrude the raw materials to form molten materials after melting and plasticizing;

[0047] The screen changer 3 is connected to the discharge port of the extruder 1 and is used to filter the molten material extruded by the extruder 1;

[0048] The inlet of the metering pump 4 is connected to the screen changer 3, the outlet of the metering pump 4 is connected to the meltblown cloth mold 5, and the metering pump 4 is used to connect to the screen changer 3 after filtering The molten material and pump t...

Embodiment 2

[0067] Such as Figure 1~5 As shown, a method for starting the melt-blown cloth production line as described in Embodiment 1, the steps of the method include:

[0068] S1: heating the barrel of the extruder 1 to a specified temperature through the heating device 2 and then keeping it warm for a period of time;

[0069] S2: In the state where the screen changer 3 is disconnected from the outlet of the extruder 1, feed raw materials into the extruder 1 through the automatic feeder to make the extruder Machine 1 melts and plasticizes the raw materials and extrudes them;

[0070] S3: In the state where no spinneret is installed in the melt-blown cloth mold 5, connect the screen changer 3 to the outlet of the extruder 1, so that the melt in the extruder 1 The material is extruded after passing through the screen changer 3, the metering pump 4 and the meltblown cloth mold 5; Clean up to prevent the spinneret from being blocked due to raw materials not reaching a molten state, and...

Embodiment 3

[0075] Such as Figure 1~5 As shown, a method for producing melt-blown cloth, the method is implemented based on the melt-blown cloth production line as described in Embodiment 1, and the steps of the method include:

[0076] M1: the extruder 1 connects the raw material and extrudes the raw material to form a molten material after melting and plasticizing;

[0077] M2: the screen changer 3 filters the molten material extruded by the extruder 1;

[0078] M3: the metering pump 4 is connected to the molten material filtered by the screen changer 3 and pumped into the meltblown cloth mold 5 at a certain pressure;

[0079] M4: The air supply device sends hot air into the melt-blown cloth mold 5, and the molten material in the melt-blown cloth mold 5 is ejected by the hot air to form fiber filaments;

[0080] M5: The web forming machine 6 accepts and absorbs the fiber filaments so that the fiber filaments are formed into a melt-blown cloth in the web forming machine 6 .

Abstract

The invention discloses a melt-blown fabric production line, a startup method, and a melt-blown fabric production method. The melt-blown fabric production line comprises an extruder, a heating device,a screen exchanger, a measuring pump, a melt-blown fabric die, a gas supply device and a screen former, wherein the extruder is used for feeding raw materials, carrying out melting-plasticizing on the raw materials, and then extruding to form melt materials; the screen exchanger is connected with a discharge port of the extruder and used for filtering the melt materials which are extruded by theextruder; the measuring pump is used for feeding the melt materials which are filtered by the screen exchanger and feeding the fed melt materials into the blown fabric die by a certain pressure pump;and the gas supply device is used for feeding hot air into the blown fabric die, so that the melt materials in the blown fabric die are blown through the hot air to form fiber yarns. According to themelt-blown fabric production line, the startup method, and the melt-blown fabric production method, the pressure of the melt materials can be stabilized, the production quality for the melt-blown fabric can be improved, and moreover, the automation degree of production can be increased, the operation can be simplified, the labor cost of production can be lowered, and the production efficiency canbe increased.

Description

technical field [0001] The invention relates to a meltblown cloth production line, a start-up method and a meltblown cloth production method. Background technique [0002] At present, melt-blown cloth is the core material for the production of masks. In the production process of melt-blown cloth, the raw materials need to be extruded and plasticized into molten materials through an extruder, and the molten materials are then sprayed out through a melt-blown cloth mold to produce melt-blown cloth. However, in the existing melt-blown cloth production line, the pressure of the molten material is unstable, resulting in poor quality of the produced melt-blown cloth, which cannot reach the 95 standard, and in the existing melt-blown cloth production line, the screw in the extruder needs It bears a large axial force, which reduces the service life of the screw. In addition, the existing melt-blown cloth production line has a low degree of automation, requires multiple people to o...
