Description
Technical field
The utility model belongs to the technical field of plastic packing product production equipment, and in particular to a kind of by plastic sheet heat
Pressure is processed into the hot pressing machine-shaping device of plastic packing product.
Background technology
Plastic sheet（I.e. coiled plastic sheet）Plastic containers product, such as Gel can be processed into by hot-forming
Cup of curry fruit jelly food etc. etc., the equipment for implementing above-mentioned process are exactly plastic sheet hot pressing machine-shaping device.
Plastic sheet hot pressing machine-shaping device includes haulage gear, heating arrangements, compressing mechanism, punching mechanism；
Compressing mechanism is provided with mould, forms several cavitys in mould, and each cavity distribution turns into that M is horizontally-arranged, N files；Adjacent lines
Or/and cavity gap is there are between adjacent column cavity.
During work, coiled plastic sheet（Coiled plastic material）Gradual unwinding simultaneously takes production line, and is drawn by haulage gear
Plastic sheet advance, receives to be heated to soft state when plastic sheet passes through heating arrangements, when plastic sheet is by suppressing
It is pressed during shaping mechanism, the plastic sheet of soft state is close to the type face of mould, obtains and die face phase
Imitative cavity shapes, then cooling and shaping, the demoulding, punching, each punching can obtain M × N number of plastics package with cavity
Product.The mode of above-mentioned compressing action includes a variety of, common are three kinds of mechanical pressure, negative pressure plastic uptake, positive air pressure bases
This method, the mode of wherein negative pressure plastic uptake are the type faces for making plastic sheet be close to mould using vacuum suction, the side of positive air pressure
Formula is that blowout carries the gas of certain pressure and plastic sheet is close to the type face of mould, and the mode of mechanical pressure is to utilize top pressure
Plastic sheet top pressure is entered die cavity therein and is close to the type face of mould by part, and top pressure part can be the formpiston coordinated with cavity
Tool either push rod；Above-mentioned three kinds of basic skills can be applied in combination.
In order that the plastic packing product of concave-convex surface can be formed with pattern, CN100475492C devises a kind of production
Technique, it is printed with multiple plane patterns, position, spacing and the die cavity therein of each group of plane pattern on plastic sheet in advance
Position, spacing it is corresponding, i.e., each group of pattern is also disposed to for M is horizontally-arranged, N files, and during compressing, allows plane
The cavity of the position alignment mould of pattern, so, it is compressing after product ridge also just carried relief pattern, and
Although above-mentioned pattern is finally concavo-convex, can be printed prior using ripe, exquisite lithography techniques.
In the prior art, plastic sheet receives the area size that heating arrangements are heated and corresponds to plastic sheet each time
Upper M × N number of pattern region size, and be linked to be whole piece and carry out unified heating, during heating, by heat block from vertical
Plastic sheet heating position is clamped up and down, heat block is close to plastic sheet and transmits heat.Above-mentioned mode of heating exist with
Lower deficiency：First, when the heating-up temperature of needs is higher or heat resistance is poor, plastic sheet is easily heated block and burns or seriously scald
Wound, the plastics close to molten condition easily sticky arrive heat block surface；2nd, when the depth-width ratio of product reaches 1.2:1 or so even
When bigger, it is meant that plastic containers recess stretch ratio is big, and then means the thickness of the plastics at position during unstamped shaping
Greatly, weight is big, and requires that softening degree is high, heating-up temperature is high, and the plastic sheet position that such softening degree is high, weight is big exists
After heating, it is easy to due to slavering over（Center drops）And irregular stretcher strain occurs, particularly pulled in plastic sheet
During, irregular horizontal stretch deformation more likely occurs due to the transmission of horizontal drag force, plastic sheet is irregularly drawn
The irregular stretcher strain of pattern can be caused by stretching the result of deformation, ultimately resulted in the pattern and character after shaping and gone out irregular deformation.Institute
The depth-width ratio of product is called, refers to the cavity height of product the ratio between with cavity width.In each product cavity, its cavity opening across
The size of degree maximum is referred to as cavity length, and the full-size on the direction vertical with cavity length is referred to as cavity width.Cavity
Highly it is also cavity depth.
Utility model content
The purpose of this utility model is to overcome disadvantages mentioned above and provide a kind of plastic sheet hot pressing machine-shaping device, it
Plastic sheet can be avoided to be burned in heating process, while mitigate plastic sheet pattern during traveling and irregularly stretch change

The utility model has advantages below and effect：
First, in the utility model production process, the position that plastic sheet is not softened by the position of thermal softening is separated into
Multiple disconnected regions, the position not softened can be such that the size in the region of each maceration significantly reduces, therefore
Maceration edge can be reduced and slaver over tenesmus and under tension due to overall, mitigate the degree of maceration tenesmus deformation, subtract
The degree of the light heated maceration irregular deformation of plastic sheet；On the other hand, in plastic sheet in by drawing traveling process,
The position that plastic sheet does not soften, while the lower folder frame edge of servomotor drive mechanism driving can be held by lower folder frame
Longitudinal rail moves horizontally, and the speed for moving horizontally lower folder frame is equal to the speed that plastic sheet advances, and does not soften portion so
What position was subject to involves pulling force very little, makes the traction force for passing to maceration smaller, the position without softening can pull
Protect-ing frame structure in journey as maceration, make the degree of the irregular stretcher strain of plastic sheet pattern during traveling more
Slightly.
When the 2nd, heating, plastic sheet is clamped at clamping face position, due to heating block and clamping face stagger one section vertically away from
From heating block is not directly contacted with plastic sheet, therefore avoids plastic sheet heat block from burning or rats after severe scald burn, also avoids proximity to melt
The plastics that melt are sticky to arrive heat block surface.
