Abstract
A fusion welding die set of non-PVC film for making plastic packing bag is composed of an upper die with cooling plate and a lower die, and features that said upper and lower dies have the holes in which the electrically heating rods and the thermoelectric couple are inserted.
Description
Technical field
The present invention relates to a kind of non PVC film welding mould, belong to the bag welding and forming device in the non-PVC film full automatic bag making, filling and sealing machine, be the auxiliary facility of non-PVC film full automatic bag making, filling and sealing machine pharmaceutical machine.
Background technology
The non PVC film welding mould that one cover is complete is made up of mold, mold heating plate, last coldplate, bed die, bed die heating plate and following coldplate.In the wherein upper and lower mold heated plate electrically heated rod and thermocouple are housed respectively, in order to control the operating temperature of upper and lower mould, by plate the contact of plate form are conducted heat between heating plate and the mould respectively.In the middle of upper and lower die-face, process a groove respectively in order to inlay upper and lower coldplate respectively.When non-PVC film moved to up and down between the mould, upper and lower coldplate moved at first, and the non-solder side of non-PVC film is compressed cooling, prevented that non-PVC film from melting, and mould moves simultaneously up and down then, with non-PVC film periphery welding fabrication.
But, owing to be that a kind of plate conducts heat to the contact of plate form between heating plate and the mould, inevitably there is a large amount of thermal losses in the centre, and electrically heated rod and thermocouple are installed on the heating plate, so in fact control is the temperature on heating plate temperature inside rather than mold work surface, so not only caused a large amount of thermal losses, wasted the energy, also cause the control of mold work surface temperature inaccurate easily, influence the attractive in appearance and peripheral weld strength of bag type, directly have influence on the qualification rate of product.And this mould needs the flatness and the depth of parallelism of high request in the course of the work, produce when the necessary three kinds of mould specifications of infusion solutions (100ml, 250ml, 500ml) are mutual to be changed, to replace with respectively, bed die and upper and lower coldplate, Installation and Debugging are loaded down with trivial details, efficient is low, more time of needing of mold exchange long, this relatively consumptive materials of costliness of the necessary non-PVC film of a large amount of waste debugging moulds.
Summary of the invention
The object of the present invention is to provide a kind of non PVC film welding mould, can change adjustment fast, and can make the temperature control of die-face accurate, guarantee weld strength, improve product percent of pass and production efficiency.
Non PVC film welding mould of the present invention, comprise that corresponding patrix is concrete and counterdie is concrete, patrix specifically is provided with coldplate, its improvements are that concrete and counterdie is directly set up electrically heated rod jack and thermocouple jack on concrete at patrix, and electrically heated rod and thermocouple are inserted into respectively in the jack of correspondence.
At mold inner directly plug-in mounting electrically heated rod and thermocouple, mold is directly heated and the temperature of mold itself is directly detected feedback, solved original plate plate contact a large amount of thermal losses and the mold work temperature that exists of conducting heat controlled coarse phenomenon.And electrically heated rod and thermocouple are directly installed on the mold, when changing mould specification, being connected of carrying out for convenience and master control system can be installed in the lead that is connected of electrically heated rod and thermocouple on separately the mold with the form of fast plug-in unit, change regulate quick and convenient.
In counterdie is concrete, be provided with cooling liquid circulation inner chamber, be about to the concrete and coldplate of counterdie and be made as integral structure, several mould specifications, as the welding of the bag of 100ml, 250ml, 500ml etc., can a shared cover bed die, after bed die is in place and adjusts flatness, when changing specification, only need replace with mould and get final product, it is convenient to change adjustment, and cost is low.
The design of heater block of the present invention and temperature-measuring part with being integral of mould structure, reduced hot slippages, saved energy consumption, the temperature detection feedback of mould directly accurately, be convenient to accurate control, improve weld strength, guarantee welding quality, the product percent of pass height, and plug-in mounting mode and bed die integrated design have been adopted, it is quick and convenient to change adjusting, and cost is low, the production efficiency height.
Description of drawings
Fig. 1, one embodiment of the invention structural representation.
Among the figure: 1, concrete 2, the coldplate 3 of patrix, non-PVC film periphery welding profile 4, the concrete electrically heated rod 5 of patrix, mold body heat galvanic couple 6, the concrete electrically heated rod 7 of counterdie, bed die body heat galvanic couple 8, counterdie are concrete.
The specific embodiment
The invention will be further described in conjunction with the foregoing description accompanying drawing.
As shown in the figure, non PVC film welding mould of the present invention, comprise corresponding patrix concrete 1 and counterdie concrete 8, patrix specifically is provided with coldplate 2, be provided with cooling liquid circulation inner chamber in the counterdie concrete 8, be about to counterdie concrete 8 and coldplate and be made as integral structure, establish electrically heated rod jack and thermocouple jack on patrix concrete 1 and counterdie concrete 8, concrete 1,8 electrically heated rod 4,6 of upper and lower mould and thermocouple 5,7 are inserted into respectively in each self-corresponding jack.
2 pairs of non-PVC films of coldplate on the patrix concrete 1 cool off, non-solder side when preventing to weld melts owing to temperature is too high, and only process non-PVC film periphery welding profile 3 at the concrete 1 welding job face of patrix, counterdie concrete 8 adopts integrated design, it is one flat plate, like this, the control of bag type just only is subjected to non-PVC film periphery welding profile 3 controls in the patrix concrete 1, irrelevant with counterdie concrete 8, like this when changing specification, only need replace with mold 1 and get final product, reduce more mold exchange time and mould adjustment time.
Claims (2)
1, a kind of non PVC film welding mould, comprise that corresponding patrix is concrete and counterdie is concrete, patrix specifically is provided with coldplate, it is characterized in that concrete and concrete electrically heated rod jack and the thermocouple jack of being provided with of counterdie of patrix, and electrically heated rod and thermocouple are inserted into respectively in the corresponding jack.
2, non PVC film welding mould according to claim 1 is characterized in that counterdie is provided with cooling liquid circulation inner chamber in concrete.
