Three side edge-folding mechanisms, are shown here only a kind of embodiment.
The fold method of edge-folding mechanism 5 is as follows:The plastic sheet 45 to flanging is fixed on positioning mechanism 4 first, it is vertical to drive
Mould group drives two upper hem knives 51 to push, and will roll under the both sides of plastic sheet 45 respectively, vertical that mould group is driven to drive upper hem knife 51
It resets, horizontal drive mould group drives the mutual closing of two lower hem knife 52, and vertical 45 edge of plastic sheet is bent inwardly.
Specifically, the upper hem knife 51 includes heat insulation pedestal 511, heat-conducting plate 512, the first thermal insulation board 513, the second thermal insulation board
514, the bottom surface of electrically heated rod, the heat insulation pedestal 511 is inclined-plane, and the heat-conducting plate 512 is attached at the bottom of heat insulation pedestal 511
The bottom surface in face, heat-conducting plate 512 is vertical and flushes with the side of heat insulation pedestal 511, and first thermal insulation board 513 is attached at heat-insulated bottom
The side of seat 511, the bottom surface of the first thermal insulation board 513 is horizontal simultaneously to be flushed with the lower edge of 511 bottom surface of heat insulation pedestal, described second every
Hot plate 514 is attached at 512 side of heat-conducting plate, and the bottom surface of the second thermal insulation board 514 is horizontal and neat with the lower edge of 512 bottom surface of heat-conducting plate
Flat, the bottom surface of the heat insulation pedestal 511 offers fixing groove 515, the electrically heated rod be installed in fixing groove 515 and with it is thermally conductive
Plate 512 contacts, and the thermal coefficient of first thermal insulation board 513 is lower than the thermally conductive system of heat insulation pedestal 511 and the second thermal insulation board 514
Number.
Existing upper hem knife 51 is usually a kind of stainless steel knife of heated type, is equipped with electrically heated rod in cutter and is heated,
When upper hem knife 51 and plastic sheet 45 contact, cutter heats the edge of plastic sheet 45, to carry out flanging.But this cutter
Because stainless steel material is made, heat is easy Quick diffusing into air, and heat energy loss is serious, and electrically heated rod needs to heat on cutter
It works to 150-200 degree, electrically heated rod electricity consumption is big, increases energy loss and production cost;And this cutter
Bottom surface is horizontal plane, and big with 45 contact area of plastic sheet, i.e., heating surface (area) (HS is big, and being also possible to when contacting with plastic sheet 45 can be because
The excessively high scald plastic sheet 45 of temperature causes 45 edge of plastic sheet to wrinkle, so that the edge out-of-flatness of plastic sheet 45, influences flanging effect
Fruit.
In the present invention, upper hem knife 51 in the side of heat insulation pedestal 511 by being sticked the first thermal insulation board 513, in heat insulation pedestal 511
Ramped bottom surface be sticked heat-conducting plate 512 and the second thermal insulation board 514, form stair-stepping working end.When upper hem knife 51 works, every
Heat is transferred directly to heat-conducting plate 512 by the electrically heated rod built in hot pedestal 511, and the width of the vertical bottom surface of heat-conducting plate 512 is
1.2 ㎜, accurately contact with the edge of plastic sheet 45 during flanging and are allowed to heated and be easy to bend, meanwhile, with plastic sheet 45
First thermal insulation board 513 of contact, which again can fully obstruct heat with plastic sheet 45, to come, and guarantees that non-tuck portion is notheated
Corrugation, ensure that flanging effect;In addition, the heat loss of electrically heated rod has been delayed in heat insulation pedestal 511 and the resistance of the second thermal insulation board 514,
Electrically heated rod only needs heat-conducting plate 512 being heated to 70-80 degree can to work, and is greatly saved the energy and cost, also, first every
The thermal coefficient of hot plate 513 is lower than the thermal coefficient namely heat insulation pedestal 511 of heat insulation pedestal 511 and the second thermal insulation board 514 and the
Two thermal insulation boards 514 still retain certain heat spreading function, and upper hem knife 51 is made to guarantee necessary heat dissipation, to prevent the heat of upper hem knife 51
Amount aggregation is excessive to be influenced to work normally.
Specifically, the heat-conducting plate 512 is made of copper material.
In the present embodiment, the preferred copper material of heat-conducting plate 512 is made, and copper material heating conduction is good, is used for 45 side of heating of plastic piece
Edge, effect are obvious.
Specifically, first thermal insulation board 513 is made of compound stone material.
In the present embodiment, the preferably synthetic stone material of the first thermal insulation board 513 is made, compound stone high temperature resistant, can play well every
Heat effect.
Specifically, the heat insulation pedestal 511 and 514 fibreglass material of the second thermal insulation board are made.
In the present embodiment, heat insulation pedestal 511 and the preferred glass fiber material of the second thermal insulation board 514 are made, glassfiber insulation
Well, heat resistance is strong, can be by the reservation appropriate of the heat of electrically heated rod.
Specifically, the driving end of the vertical driving mould group is connect by upper tool post with upper hem knife 51, and the upper tool post is equipped with
With the slide bar 57 of 51 horizontal vertical of upper hem knife, the upper hem knife 51 is socketed on 57 surface of slide bar, and the upper hem knife 51 is opened
Positioning screw hole equipped with straight-through slide bar 57 passes through positioning screw hole by bolt and pushes against slide bar 57, and upper hem knife 51 is fixed on cunning
On bar 57.
Using the above scheme, moved by upper hem knife 51 along slide bar 57, adjustable upper hem knife 51 and plastic sheet 45 away from
From to adapt to the flanging to various sizes of plastic sheet 45.In the present embodiment, the slide bar 57 is screw rod, and upper hem knife 51 is logical
It crosses nut and is placed on screw surface, bolt passes through upper hem knife 51 and nut is butted on screw rod.
Specifically, the board 1 is equipped with the guide rod 58 with 52 horizontal vertical of lower hem knife, and the lower hem knife 52 passes through sliding block
It is socketed on 58 surface of guide rod.
Using the above scheme, guide rod 58 is that the movement of lower hem knife 52 provides guiding role, keeps lower hem knife 52 mobile steady.
In the present embodiment, it is the combination of motor and screw rod driving pair that the flanging drives mould group 53 vertically, and the flanging level is driven
Dynamic model group 54 is cylinder.
