A fixed spinneret die is fixedly installed on a fixed spinning box body, and a movable spinneret die is fixedly installed on a movable spinning box body. During the process of the melt being ejected through the fixed spinneret die and the movable spinneret die, the fixed spinneret die remains stationary, and the movable spinneret die makes a reciprocating linear motion along the length direction of the steel platform driven by a moving component, thereby adjusting the distance between the movable spinneret die and the fixed spinneret die. The movable spinneret die makes a reciprocating linear motion along the height direction of the steel platform driven by a lifting component, thereby adjusting the distance between the movable spinneret die and the web forming machine. The present invention adopts a fixed spinneret die and a movable spinneret die, and the movable spinneret die is adjustable. The double-layer composite meltblown fabric produced by this adjustable dual spinneret system effectively solves the drawbacks of traditional single spinneret meltblown fabric, such as uneven fabric basis weight, large resistance, low filtration efficiency, and poor hand feeling.

Description

Technical Field

[0001] The present invention relates to the technical field of meltblown cloth production equipment, and more particularly to an adjustable dual die head meltblown cloth production system. Background Art

[0002] In the traditional production line of meltblown cloth, during the production process of non-woven fabric, the melt is ejected through a spinneret to form primary filaments. After being cooled by side air blowing, it enters a stretcher and is stretched into long filaments by air flow, then the filaments are laid into a web, and then dried and electret-treated in sequence to form a non-woven fabric with a certain filtering effect. However, the traditional production line only has a single die head. During the process of the melt being ejected through the spinneret to form primary filaments, the gram weight of the meltblown cloth surface ejected by the single die head is uneven, with large resistance, low filtering efficiency, and poor hand feeling. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to overcome the problem that the traditional production line of meltblown cloth only has a single die head, and during the process of the melt being ejected through the spinneret to form primary filaments, the gram weight of the meltblown cloth surface ejected by the single die head is uneven, with large resistance, low filtering efficiency, and poor hand feeling, and to provide an adjustable dual die head meltblown cloth production system.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an adjustable dual die head meltblown cloth production system, including a steel platform, on which a mixer, a screw extruder, a hot air heater, a screen changer, a metering pump, and a fixed spinning box are sequentially arranged. The fixed spinning box is arranged on the steel platform through a lifting component. Below the steel platform, a web forming machine, an electret equipment, and a slitting and winding machine are sequentially arranged. The screw extruder and the hot air heater are both communicated with the fixed spinning box. A fixed spinneret die head is arranged on the fixed spinning box, and the fixed spinneret die head is communicated with the fixed spinning box. The fixed spinneret die head is located directly above the web forming machine.

[0005] A moving component is fixedly installed on the steel platform. An lifting component is fixedly installed on the moving component. A moving spinning box is fixedly installed on the lifting component. The moving spinning box is communicated with both the screw extruder and the hot air heater. A moving spinneret die head is fixedly installed on the moving spinning box, and the moving spinneret die head is communicated with the moving spinning box. The moving component drives the moving spinning box to perform a reciprocating linear motion along the length direction of the steel platform, and the lifting component drives the moving spinning box to perform a reciprocating linear motion along the height direction of the steel platform.

[0006] An adjustable double spinneret meltblown fabric production system of the present invention includes a fixed spinning box body and a movable spinning box body. A fixed spinneret is fixedly installed on the fixed spinning box body, and a movable spinneret is fixedly installed on the movable spinning box body. During the process of the melt being ejected through the fixed spinneret and the movable spinneret, the fixed spinneret remains stationary, and the movable spinneret makes a reciprocating linear motion along the length direction of the steel platform driven by a moving component, thereby adjusting the distance between the movable spinneret and the fixed spinneret. The movable spinneret makes a reciprocating linear motion along the height direction of the steel platform driven by a lifting component, thereby adjusting the distance between the movable spinneret and the web forming machine. The present invention adopts a fixed spinneret and a movable spinneret, and the movable spinneret is adjustable. The double-layer composite meltblown fabric produced by this adjustable double spinneret system effectively solves the drawbacks of traditional single spinneret meltblown fabric, such as uneven fabric grammage, large resistance, low filtration efficiency, and poor hand feeling.

[0007] In order to enable the moving component to drive the movable spinning box body to make a reciprocating linear motion along the length direction of the steel platform, the moving component includes a pneumatic slide rail. The pneumatic slide rail is fixedly installed on the steel platform and is arranged along the length direction of the steel platform. A slider is slidably installed on the pneumatic slide rail, and the slider can make a reciprocating linear motion on the driving slide rail.

[0008] In order to enable the lifting component to drive the movable spinning box body to make a reciprocating linear motion along the height direction of the steel platform, the lifting component includes a mounting plate. The mounting plate is fixedly installed on the slider, and a positive and negative thread lifting mechanism is fixedly installed on the mounting plate. The movable spinning box body is fixedly installed on the positive and negative thread lifting mechanism.

[0009] Furthermore, the positive and negative thread lifting mechanism includes an upper reverse thread adjusting stud, a lower positive thread adjusting stud, and a positive and negative thread adjusting nut. The upper reverse thread adjusting stud and the lower positive thread adjusting stud are threadedly connected through the positive and negative thread adjusting nut. The upper reverse thread adjusting stud is fixedly connected to the slider, and the lower positive thread adjusting stud is fixedly connected to the movable spinning box body. By rotating the positive and negative thread adjusting nut forward and backward, the mutual approach and mutual separation of the upper reverse thread adjusting stud and the lower positive thread adjusting stud can be realized. After the upper reverse thread adjusting stud and the lower positive thread adjusting stud approach each other, the distance between the movable spinning component and the web forming machine increases. When the upper reverse thread adjusting stud and the lower positive thread adjusting stud move away from each other, the distance between the movable spinning component and the web forming machine decreases.

[0010] After the distance adjustment is completed, during the spinning process, in order to prevent the positive and negative thread adjusting nut from rotating, a reverse thread locking nut is threadedly installed on the upper reverse thread adjusting stud, and a positive thread locking nut is threadedly installed on the lower positive thread adjusting stud. The positive and negative thread adjusting nut is located between the reverse thread locking nut and the positive thread locking nut, and the reverse thread locking nut and the positive thread locking nut limit the positive and negative thread adjusting nut between them.

[0011] The beneficial effects of the present invention are as follows: An adjustable dual spinneret meltblown fabric production system of the present invention includes a fixed spinning box body and a movable spinning box body. A fixed spinneret is fixedly installed on the fixed spinning box body, and a movable spinneret is fixedly installed on the movable spinning box body. During the process of the melt being ejected through the fixed spinneret and the movable spinneret, the fixed spinneret remains stationary, and the movable spinneret makes a reciprocating linear motion along the length direction of the steel platform driven by a moving component, thereby adjusting the distance between the movable spinneret and the fixed spinneret. The movable spinneret makes a reciprocating linear motion along the height direction of the steel platform driven by a lifting component, thereby adjusting the distance between the movable spinneret and the web forming machine. The present invention adopts a fixed spinneret and a movable spinneret, and the movable spinneret is adjustable. The double-layer composite meltblown fabric produced by this adjustable dual spinneret system effectively solves the drawbacks of traditional single-spinneret meltblown fabric, such as uneven fabric grammage, large resistance, low filtration efficiency, and poor hand feeling.
