Description
Technical field:
The present invention relates to field of plastics processing, is a kind of plastic extrusion and absorption integrated forming circular production process specifically.
Background technology:
Domesticly existing squeeze, the plastic uptake forming system production technology, its roughly step be:
1, plastic materials such as PE, PP, PET extrude, are cooled to the rolling sheet material such as PE, PP, PET of all size by the high temperature heating plasticizing.
2, rolling sheet materials such as PE, PP, PET through the high temperature heating, become the food product packets harness of various model once more through the vacuum forming of Packing Machine.
3, stamping-out goes out in the semifinished or finished goods process to remain rim charge after crushed, adds in the raw material again and uses.
4, have shortcoming crowded, the plastic uptake forming system production technology now:
A, production technology program are many.At first must go out the rolling sheet material by extrusion molding, sheet material need pass through the post bake plastics sucking moulding again.
B, energy resource consumption are big.In the post bake process of rolling sheet material, need to expend a large amount of electric energy.
Taking of C, production space.By the rolling sheet material that extrusion molding comes out, need take bigger production space and storage space, be unfavorable for field management and increased management cost.
D, be subject to secondary pollution.The rolling sheet material is in the storage process, and is long time of contact with air, is subject to secondary pollution.
E, learies are big.In the process of post forming, increased the moulding difficulty because of weighing down sheet, cause and scrap too much, increased production cost.
Summary of the invention:
For solving the problem that prior art exists, the invention provides a kind of plastic extrusion and absorption integrated forming circular production process, the sheet material that comes out by extrusion molding need not to cool off heating more directly plastic uptake become the food container of all kinds of models, saved because of electric energy in the post bake plastics sucking moulding and heat energy, simplified several procedures, saved a large amount of time, greatly improved production efficiency, it is artificial also to have saved simultaneously operation, has saved spending, for enterprise creates economic benefit.
The technical solution used in the present invention:
The plastic uptake integrated forming circular production process is characterized in that, may further comprise the steps:
(1) raw material stirs, and all kinds of raw materials evenly stir in mixer by the pipeline input in the ratio of setting in the material container, are convenient to plasticizing, and whipping temp is: the 50-80 degree;
(2) raw material that stirs in the mixer is transferred in the raw material transport trolley by delivery outlet;
(3) raw material on the raw material transport trolley is input in the crowded plastic uptake all-in-one by barrel according to actual needs;
(4) squeeze raw material in the plastic uptake all-in-one under the plasticizing of machine screw rod high temperature, in blocks by the roll extrusion of the extruding of die head, cylinder, plasticization temperature is: the 180-250 degree;
(5) in the continual extrusion of high temperature sheet material, by squeezing the plastic uptake all-in-one, synchronous vacuum suction moulding;
(6) semi-finished product after the moulding are through ultraviolet sterilization; Under driving, the rim charge draw-gear is transported to the pulverizer pulverizing automatically and cut out the remaining rim charge in back through the blowing pipeline at machinery;
(7) semi-finished product after purifying through manually cut out, operation output finished products such as machine is die-cut, packing;
(8) rim charge after pulverizing between crushing vehicle directly is transported in the high floor rim charge reservoir vessel through air-suction duct by the rim charge EGR;
(9) rim charge in the rim charge reservoir vessel re-enters in the mixer through pipeline with the raw material in the material container according to a certain percentage and stirs, and begins the circulation plasticizing and uses;
Described plastic extrusion and absorption integrated forming circular production process, it is characterized in that: described chassis mould linkage, chassis mould linkage is positioned at extruding machine plastics sucking moulding section, mainly comprise parts such as mould, chassis, support arm, screw mandrel, cylinder, the chassis is connected on the extrusion moulding machine by support arm and screw mandrel, mould is fixed on the chassis, plastics sucking moulding motion about chassis mould linkage is done by cylinder drive chassis, screw mandrel drive the chassis and do the round contact pin campaign in front and back, are synchronized with the sheet material plastics sucking moulding of uninterruptedly extruding.
Described plastic extrusion and absorption integrated forming circular production process is characterized in that: described raw material is plastic materials such as PE, PP, PET, and its concrete composition is adjustable according to producing needs.
Advantage of the present invention:
1, the saving of electric energy and heat energy.The sheet material that comes out by extrusion molding need not to cool off heating more directly plastic uptake become the food container of all kinds of models, saved because of electric energy in the post bake plastics sucking moulding and heat energy, active response national energy-saving and cost-reducing requirement.
2, the saving in production space.The sheet material of all kinds of materials of producing need not to seek accommodation space and place, becomes the varieties of food items packing container and be directly used in plastic uptake, has not only simplified operating process, but also has saved semi-finished product and stacked space, the efficient of the field management of raising.
3, the raising of product quality, health.By the sheet material straight forming that new technology high temperature plasticizing is extruded, reduced the time of contact with air, prevent sheet cools and stacked possible because of the secondary pollution that causes with the air Long contact time, guaranteed the quality and the health of product effectively.
4, the raising of production efficiency and personnel's saving.This process program expect that from former sheet material to direct plastics sucking moulding, simplified several procedures, saved a large amount of time, greatly improved production efficiency, also saved 3-4 name operating personnel simultaneously, saved spending.
5, the raising of formed product effect.Cooled sheet material because of being subjected to the influence of environment temperature, is easy to weigh down the sheet modification in heating process again, the formed product effect is undesirable, scraps more; And using the control of backing material that new technology extrudes by technological means, sheet temperature is evenly, plastic uptake puts in place, finished product grammes per square metre error is little, has significantly reduced learies.
6, the virus killing decontamination procedure is simplified.The backing material that the high temperature plasticizing is extruded can effectively be removed the bacterium that is adsorbed on sheet surface, and omit the virus killing in the sheet material post bake, has simplified production routine, has saved cost.
7, automaticity improves, improved efficiency.With respect to existing rim charge circulation technology, the automaticity of new technology significantly improves, and it is extremely pulverized from the automatic traction of rim charge, is transported to stirring after the pulverizing, and the automation of a series of circulation link has improved the efficient of producing widely.
8, this technology has reduced the generation of rim charge, has improved the service efficiency of sheet material.Former technology needs cutting sheet material both sides when pulling-on piece; In addition when plastic uptake, because of fixing sheet material also needs cutting sheet material both sides, technology is compared therewith, and former technology has the generation of twice rim charge, and new technology only produces rim charge one time, has improved the sheet material service efficiency.
