Description

A kind of plastic extruder filters threeway

Technical field

The utility model is related to package packing machine field, and especially a kind of plastic extruder filters threeway.

Background technology

Plastic extruder employed both at home and abroad filters the heating of threeway at present, typically in the filtration three of an oblate type Logical upper installation strip heater, not only firing rate is slow, it usually needs the time of more than 2 hour, and heat time underswell is time-consuming Between and power consumption, and plastic melt filter threeway in be detained produce oxidation and affect product quality, oxidation deterioration also wastes former Material.

Content of the invention

The purpose of this utility model is to overcome drawbacks described above, provides a kind of plastic extruder to filter threeway, filters threeway bag Housing 4, screen pack 14, gland 7 are included, housing 4 and extruder barrel 1 pass through thread connection, gland 7 passes through screw 8 with housing 4 Connection, screen pack 14 be arranged between barrel 1 and gland 7 it is characterised in that：More than 4 deep holes 3 are designed with described housing 4, In deep hole 3, electrothermal tube is installed.

Preferably, being designed with porous plate 13, discharging chamber 5, discharge opening 10, boss 11 and step 12 in described gland 7, many Orifice plate 13, discharging chamber 5 and boss 11 outer surface and discharge opening 10 hole wall are high burnishing surface and scribble hard metal chromium, in discharging chamber 5 It is designed with step 12 and boss 11, porous plate 13 is engaged with step 12, boss 11.

Preferably, the electric heating pipe joint on described housing 4 is provided with protective cover, protective cover is fixed on housing 4.

The beneficial effects of the utility model：Using the art of this patent, the firing rate of filter is from original little more than 2 When accelerate to half an hour, not only save the heat time, the waste also saved power consumption and reduce Head material, increase substantially product Quality, production efficiency and Business Economic Benefit.

Brief description

Fig. 1 is the structural representation of one embodiment of apparatus of the present invention；

Fig. 2 is the house portion structure schematic diagram of one embodiment of apparatus of the present invention；

Specific embodiment

Further describe embodiment below in conjunction with accompanying drawing：

With reference to Fig. 1, Fig. 2：1- extruder barrel, 2- housing A end face, 3- deep hole, 4- housing, 5- discharging chamber, 6- housing B end Face, 7- gland, 8- fixing screws, 9- screw, 10- discharge opening, 11- boss, 12- step, 13- porous plate, 14- screen pack, one Plant plastic extruder and filter threeway, filter threeway and include housing 4, screen pack 14, gland 7, housing 4 is led to extruder barrel 1 Cross thread connection, gland 7 is coupled by screw 8 with housing 4, and screen pack 14 is arranged between barrel 1 and gland 7, described housing 4 On be designed with more than 4 deep holes 3, be from housing A end face dress electrothermal tube enter deep hole 3 in, be designed with gland 7 porous plate 13, Discharging chamber 5, discharge opening 10, boss 11 and step 12, porous plate 13, discharging chamber 5 and boss 11 outer surface and discharge opening 10 hole wall For high burnishing surface and scribble hard metal chromium, in discharging chamber 5, it is designed with step 12 and boss 11, porous plate 13 and step 12, boss 11 ends contact cooperations, the electric heating pipe joint on housing 4 is provided with protective cover, and protective cover is fixed on housing 4, filters threeway work When making, filter threeway and heat together with the plastic extruder before and after it and die head, the heating filtering threeway is by some Electrothermal tube electrified regulation in deep hole 3, because heating tube is carried out in the inside filtering three-way body 4, the fast efficiency high of firing rate, Thus overcome that heating wire externally heated slow shortcoming is usually used, make extruder, filtration threeway and die head three's temperature same Step reaches specifies index, and typically in half an hour, the heat time more originally filtering threeway greatly shortens, and meanwhile, extruder squeezes Go out plastic melt and flow through screen pack 14, porous plate 13, discharging chamber 5 and discharge opening 10, due to porous plate 13, discharging chamber 5 and boss 11 outer surfaces and discharge opening 10 hole wall are high burnishing surface and scribble hard metal chromium, all plastic melts flowing through will not be detained, gram Take existing filtration threeway melt to be detained generation oxidation and affect the defect of product quality, the electric heating pipe joint peace of housing A end face 2 Equipped with protective cover, effective guarantee can keep the safety in production, and improve the aesthetic in appearance of product.

The beneficial effects of the utility model：Using the art of this patent, the firing rate of filter is from original little more than 2 When accelerate to half an hour, not only save the heat time, the waste also saved power consumption and reduce Head material, increase substantially product Quality, production efficiency and Business Economic Benefit.
