Description

The tray shaping mechanism of full-automatic controlled atmosphere hard packet packer

Technical field

The utility model relates to packaging facilities, and in particular to a kind of tray molding machine of full-automatic controlled atmosphere hard packet packer Structure.

Background technique

On the market, most of food on the market, patch is not aquatic products, needs to carry out vacuum to food by gas-control packing device Packaging, in particular to food is placed in plastic casing, then stretched film is blocked to the upper opening of plastic casing again, while to modeling It carries out vacuumizing in magazine being re-filled with preset gas, finally stretched film heat-sealing is connected on plastic casing and then completes to pack 's.Wherein, plastic casing is to carry out in tray shaping mechanism made of thermoforming, its working principle is that first by flaky plastics The heated device of substrate is heated, and is then transported to molding machine again and plastic basis material is pressed into required shape, currently, market On heating device generally comprise the lower heating plate of a upper heating plate moving up and down and fixed setting, when plastic basis material quilt It send to after between upper and lower heating plate, plastic basis material is pressed between upper and lower heating plate and then to plastics by upper heating plate decline Substrate is heated, and this structure has a defect that once upper and lower heating plate does not measure up with placing, and will result in upper and lower Heating plate cannot be pressed together fully, have partly plastic substrate that cannot be heated well, so influence it is subsequent at Type operation；In addition, be usually that location hole is set in lower heating plate, and the guide post with location hole cooperation is arranged on pedestal, into And what the positioning of the lower heating plate of realization was placed, since the weight of lower heating plate is generally bigger, installation, which constantly needs to lift down, to be added Location hole is aligned, when putting down gently on pedestal, and dismantling by lower heating plate again later, it is also desirable to entirely lift by hot plate with guide post Lower heating plate extracts it out out of guide post, and operation is cumbersome, time-consuming and laborious.

Summary of the invention

In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide a kind of structure is simple, if Meter rationally, so that the movement of heat sealing mechanism is more smooth, and can be better achieved the heating and heat dissipation of heat sealing plate, ensures simultaneously The tray shaping mechanism of the full-automatic controlled atmosphere hard packet packer for the case where integrality of heat-sealing is not in leakage envelope.

For this purpose, the utility model is realized using following scheme:

The tray shaping mechanism of full-automatic controlled atmosphere hard packet packer, including the heating device and molding device set gradually, The molding device includes upper die and lower die, and the upper die is connected with the piston rod of molding driving cylinder, the molding Driving cylinder is fixedly mounted on upper mounted plate, it is characterised in that: the heating device includes upper heating plate, lower heating plate and bottom Seat, the upper heating plate are connect with the piston rod of heat driven cylinder, and the heat driven cylinder is fixedly mounted in fixed plate, The pedestal is in there are two I-shaped and compartment of terrain is set, the first placement counterbore to be offered at the both ends of the base top, in institute The bottom for stating lower heating plate, which is equipped with, places counterbore with the first placement counterbore corresponding second, is equipped with bullet in the first placement counterbore Spring, the top of the spring are higher by the first placement counterbore and place counterbore with wearing into second so that pedestal and lower heating plate it Between have certain interval, it is described first placement counterbore bottom end offer the threaded hole communicated therewith, it is described second place The top of counterbore offers the location hole communicated therewith, and positioning screw is bolted in the threaded hole, and the positioning screw passes through First, second placement counterbore is simultaneously worn into positioning hole.

The bottom end of the lower die is connect with heat sink, and inlet opening is offered on the heat sink, and the heat sink is placed In mounting base, the mounting base is equipped with the drainage hole being connected to inlet opening.And then ensure that lower die can carry out in time Heat dissipation.

By adopting the above technical scheme, the advantages of the utility model are as follows: by the way that spring is arranged between pedestal and lower heating plate, There is certain gap, so that lower heating plate is flexibly to be placed on pedestal, when upper heating between pedestal and lower heating plate When heating plate heats plastic basis material under plate decline compresses, even if upper and lower heating plate does not measure up with placing, lower heating plate Also slight flexible offset can occur under the extruding of upper heating plate, and be fully bonded with upper heating plate, so that upper and lower heating Each position of plastic basis material between plate can obtain identical heating effect, it is ensured that subsequent molding operation is gone on smoothly； In addition, being oriented to using positioning screw to lower heating plate, when needing to dismantle lower heating plate, positioning screw, Ji Kefang are screwed out Just it is lifted from one end of lower heating plate, without being entirely lifted lower heating plate, when needing to install lower heating plate, It only need to be directed at position, one end of lower heating plate is first resisted against on pedestal, then the overturning of lower heating plate is placed on pedestal, later The position of lower heating plate is finely adjusted again, so that positioning screw penetrates location hole, easy to operate, more time saving province Power.
