Abstract

The utility model belongs to an extrusion mould head mechanism for plastic film blowing machines, and a flow divider (13) is arranged behind a filter (12); two mould head mechanisms are arranged behind the flow divider (13); the flow passage of the extruded plastics are divided into a left and a right branch passages by the divider, and then are connected to the two mould head mechanisms behind the divider; thus a structure of one machine with two extruding mould heads is formed. The yield can be increased by nearly one time, while the power consumption can be economized by 20% than two machines, and the equipment investment, ground, staff, etc. can be reduced. The utility model is suitable for producing thin and ultra-thin films and film bags.

Description

Double mould head extruding mechanism for plastic film blowing machine

The utility model relates to plastics and extrudes process equipment, belongs to the extrusion die mechanism of plastic film blowing machine, is used for inflation film, bag film etc.

Existing plastic film blowing machine, by body, power, feed in raw material, heat, extrude, filtration, die head, blown film etc. partly form.Its extrusion die mechanism is that the screw extruder structure connects with die mechanism through filter.Die mechanism extrusion plastic cast base is after blown film mechanism blown film produces film, bag film etc., but producing ultrathin film, and during small-sized film, in the unit interval, the plastics extrusion capacity is controlled, and board production capacity is provided with to be given full play to; Too fast because of blown film mechanism revolution again, operating personnel's service speed such as does not catch up with at reason, and sticking folded the causing of the product that blows out scrapped, and output can not improve on the contrary.

The purpose of this utility model provides a kind of extrusion die mechanism, and its adopts bimodulus head, gives full play to the production capacity of inflation film manufacturing machine, enhances productivity, and increases output.

The purpose of this utility model reaches by following technical solution, it comprises screw extruder structure, filter, die mechanism, after described filter, be provided with current divider, be provided with two described die mechanism after this current divider, the circulation road that the plastics of this filter are extruded is connected with the circulation road of this current divider, be divided into left and right two tributary circulation roads through this current divider and be connected, and correspondence is provided with left flow control valve and right flow control valve on left and right two affluent channels of described current divider with the circulation road of two die mechanism of back.

The utility model is work like this, the screw rod rotation is extruded plastics and is entered filter from the stream pipe, after filtering, filter enters current divider, enter next two die mechanism through shunting from left and right affluent channel, left flow control valve and right flow control valve are regulated, are controlled left and right affluent channel.

Behind two die mechanism extrusion plastic cast bases, two corresponding blowing mould mechanisms work simultaneously, and the plastic tube parison is blown out film, and are received by two pairs of rubber rolls and smooth roll.

The utility model adopts bimodulus head extrusion mechanism, output is doubled during work, but electricity consumption saves 20% than two plastic film blowing machines, can save equipment investment, reduce place, workman etc., therefore have the effect that improves output, the saving energy, increases economic benefit.

Fig. 1 is the structure chart of the utility model in conjunction with plastic film blowing machine

Footing, 2. gear housing, 3. screw, 4. bearing, 5. nut, 6. gear, 7. suspension ring, 8. loading hopper, 9. bearing, 10. screw rod, 11. stream pipes, 12. filters, 13. current dividers, 14. die head ectosomes, 15. outlet outer rings, 16. export, 17. flow regulators.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.The screw extruder structure comprises screw rod 10, stream pipe 11.Connect filter 12 after the screw extruder structure, filter 12 backs connect current divider 13.Establish left die mechanism and right die mechanism after this current divider 13.Left and right die mechanism comprises die head ectosome 14, outlet outer ring 15, outlet 16.Plastics are clamp-oned filter (12) from the screw extruder structure and are filtered, and enter current divider 13 then.The circulation road of this current divider 13 is divided into left affluent channel and right affluent channel in the centre, and corresponding be connected with the left die mechanism of back and the circulation road of right die mechanism, left affluent channel on current divider 13 and right affluent channel correspondence are provided with left flow control valve and right flow control valve.

Claims (1)

1, a kind of plastic film blowing machine extrude the bimodulus head mechanism, comprise the screw extruder structure, filter (12), die mechanism (14.15.16), it is characterized in that: be provided with current divider (13) afterwards at described filter (12), this current divider (13) is provided with two described die mechanism (14.15.16) afterwards, the circulation road that the plastics of this filter (12) are extruded is connected with the circulation road of this current divider (13), be divided into a left side through this current divider (13), right two affluent channels are connected with the circulation road of two die mechanism of back, and the left side of described current divider (13), correspondence is provided with left flow control valve and right flow control valve on right two affluent channels.
