SJ Series LLDPE Agriculture Mulch Film Blowing Machine

SJ70-1200 / SJ75-1500


Ⅰ. Use

Its extruder,cylinder and screw rods are made of quality alloy Steel that have been nitrogen and processed in a precision way. Hence it is sound in hardness,durable in corrosion resistans.

The specially-designed screw is of sound quality in plasticizing which helps increase the production capacity.

It is applied to blowing the plastic films like Low-Density Polythylene(LDPE),High Density Polyethylene(HDPE) and Linear Low Density Polyethylene(LLDPE). It is widely applied to producing the packing bag for foodstuff,clothing rubbish,vest ones and inddustrial packaging and etc.

II. feature

  • The machine take the HDPE or LDPE as raw material, through heating, extrusion, blowing, stretch, winder and final be roll thin film.
  • The finished plastic thin film is widely used for supermarket bags, garbage bags, various plastic package bags, shopping bags,cote film and compound thin film.

IV. The structure of the film blowing machine is described as follows:

1, Extruder: motor, gear reducer, screw, barrel, die head and so on.

2, Traction auxiliary machine: traction frame, human splint, traction roller (2-3), drive shaft, roll roll and so on. It is driven by a traction motor. The tubular membrane extruded by the die mouth is drawn and stretched through the reel plate, the traction roll, the drive roll and the roll reel roll. Each part is equipped with an adjusting device to adjust when used.

3, The wind ring: from the upper and lower two parts, into the air pipe, fan and other auxiliary components. The wind is sent into the air pipe and the air ring by the fan, and the cold air is uniformly blown to the outlet of the die outlet, and the tube shaped bad film is cooled, wherein the wind ring has a regulating device to regulate the air volume.

3-4 Rotary Die Device 3-5 Double Sides Winder .. 3-6 Up and Down

..3-7 Pneumatic Device .3-8 Air Compressor

Schematic diagram of transmission film blowing machine

4, Air compressor: the compressed air is filled through the center of the air pipe and air valve from the center of the die head to the tubular bad film, and the bad film is blown to the required film width.

5. Distribution box: installation of electrical components to control the operation and heating of the whole unit (see electrical schematic diagram).



The machine working principle: the temperature up to working temperature required for raw materials, adding a hopper through the screw operation, automatically enter the feeding section, compression plasticizing, enters the die head three after filtration, the die discharging cooling after pulling collapser, traction roll again stretching, the film thickness and width, strength reach certain requirements, after the first film and roll around.

The adjustment of host temperature is based on electric heating, and the selection of temperature should be controlled by an automatic controller. It should be adjusted according to the type, performance, plasticizing index and the running speed of the whole machine. The host temperature adjustment is generally increased gradually from the feed port to three, die three tonglue low temperature ratio.

Because the heating is transferred from outside to the center, during normal operation, the partial heat produced during screw extrusion should be taken into account, and the internal control temperature difference should be adjusted appropriately, so that the temperature of each part can meet the normal requirement.

6, lift, control the size and thickness of the film, the traction button can be directly raised and down.
