3) Screw speed: 20-80r / min

4) Maximum screw pressure: 25MPa

5) Driving motor power: 15kw

6) Screw heating power: 16kw

7) Screw heating section: Zone 4

8) Equipped with stainless steel hopper, the volume is 50kg

3. Equipment composition and technical description

It is mainly composed of screw (pin mixing head form), screw barrel, electric heater, platinum thermistor, reducer, transmission system, frame, insulation cover, solution temperature detection, discharging machine neck, etc. Equipped with automatic heating and insulation, the main drive adopts frequency converter speed regulation and pressure closed-loop control. The imported temperature control instrument and solid state thermal relay are used for temperature control of each zone. Temperature control accuracy ± 1 ℃. The reducer adopts famous brand hard tooth face wide tooth large torque reducer and forced lubrication system.

The temperature control system of each zone is composed of temperature control instrument and platinum thermistor. The maximum temperature of screw mixing section is 330 ℃, and the screw drive motor is controlled by frequency converter, which is used to accurately control the screw speed.

2, 1 set of solution filter

The flange is connected with the extruder. Two groups of filter units can be set to clean and change the screen. The extruded and plasticized melt material is filtered through the filter to completely filter out the magazine and prevent blocking the spinneret hole.

Main technical parameters

Filtration accuracy: 200 μ M

Filter diameter: 80mm

Electric heating power: 2KW

3, Spinning box (including 2 metering pumps)

1. Purpose: to keep the material constant temperature in the box, and to quantitatively discharge silk through the metering pump.

2. Parameters: length 966 * width 3290 * height 1800, heating power 40kW, air inlet requirement 0.1MPa,

4, 2 sets of melt blown mould 650mm

1. High quality alloy steel heat treatment, surface mirror polishing treatment

2. Mold parameters

1) The extrusion meets the product width of 600mm,

2) Fiber thickness: 3-6 μ m (designed and made according to the sample)

3) Mold heating section 2, each zone 1500W, stainless steel heating rod.

5, 2 melt blown receivers

1. Purpose: stack the filamentous fibers ejected from the mold into a net for continuous molding.

2. Main technical parameters
