Abstract
The invention discloses a curling-inhibiting punching method for an aluminium-plastic bag, comprising the following steps of: heating the top surface of an aluminium-plastic packaging bag before punching so that material surfaces and inside aluminium layers are heated and a 15-30 DEG C temperature difference exists between a top surface layer and a bottom surface layer opposite to the top surface layer; and punching from one side of the top surface of the aluminium-plastic packaging bag to one side of a bottom surface. The deformation of the aluminium-plastic packaging bag is compensated through creating of a proper external environment so that the shell-punching and cutting effects are ensured. Poor curling of the aluminium-plastic packaging bag can be effectively inhibited, and the inhibiting means can not cause any undesirable impact on the material per se of the aluminium-plastic packaging bag or bring any inconvenience to the shell-punching and cutting process. In addition, the method provided by the invention has strong operability and can ensure the product material with less energy consumption.
Description
Technical field
The present invention relates to a kind of processing method of aluminium plastic bag, relate in particular to the method for die cutting in aluminium plastic bag cutting process.
Background technology
Aluminium plastic bag (plastic-aluminum encapsulation bag) is widely used in the product encapsulation of numerous industrial circles as the encapsulating material of function admirable.
Yet when plastic-aluminum encapsulation bag is carried out die-cut cutting, die cutting die can stretch to plastic-aluminum encapsulation bag and make it distortion, referring to Fig. 1, plastic-aluminum encapsulation bag 1 is placed on the workbench 3, otch 2 is positioned at workbench 3 edges, and plastic-aluminum encapsulation bag 1 is positioned at the part on workbench 3 right sides for needing die-cut part among the figure.Referring to Fig. 2, plastic-aluminum encapsulation bag 1 along otch 2 die-cut downwards after, remaining part can upsweep near the position of otch 2 on the workbench 3, causes the plastic-aluminum encapsulation bag after cutting a gross distortion to take place, be difficult to store and further processing.
Summary of the invention
The objective of the invention is to change the external environmental condition of plastic-aluminum encapsulation bag when die-cut, it is poor to form real-time temperature on the inside and outside two sides of plastic-aluminum encapsulation bag, suppress it by reconciliation statement layer material and inner aluminium lamination temperature and when surfacing stretches, housing is produced irreversible Texturizedly, make it behind shell, do not curl (or amount of crimp does not extremely slightly influence following process).
A kind of aluminium plastic bag method for die cutting that can suppress to curl, end face to plastic-aluminum encapsulation bag before die-cut heats, material surface and inner aluminium lamination are heated, end face and and its opposing top layer, bottom surface between 15 ℃～30 ℃ the temperature difference is arranged, from end face one side of plastic-aluminum encapsulation bag towards the bottom surface one side carry out die-cut.
As preferably, when plastic-aluminum is encapsulated the end face heating of bag, make the temperature of end face reach 40 ℃～45 ℃.After end face is heated to predetermined temperature range, need in time carry out die-cutly, can not be in the high temperature attitude for a long time, in order to avoid end face and bottom surface temperature reach unanimity gradually.
As preferably, during to the end face heating of plastic-aluminum encapsulation bag, heating incision site near zone, promptly original position of curling of easily taking place.
End face described in the present invention and bottom surface are comparatively speaking, refer to two opposing sides of plastic-aluminum encapsulation bag respectively, and are not to refer to its absolute position.
When the end face of plastic-aluminum encapsulation bag heats, but can near end face, be equipped with the switching regulator heater, and have temperature controlling function, all can adopt prior art as for plastic-aluminum pouch material itself and blanking units.
The present invention is compensated the distortion that plastic-aluminum encapsulates bag by creating suitable external environment, to guarantee towards shell and to cut effect.Can effectively suppress bad the curling of plastic-aluminum encapsulation bag, and these inhibition means can be to any harmful effect of plastic-aluminum pouch material generation itself, the shell that also can not liquidate cuts operation and causes any inconvenience.The inventive method is workable in addition, the assurance that the enough few energy resource consumptions of energy bring product material.
Description of drawings
Fig. 1 is the schematic diagram before the aluminium plastic bag material die in the prior art;
Fig. 2 is the schematic diagram after the aluminium plastic bag material die in the prior art;
Fig. 3 is the schematic diagram that utilizes before the inventive method is carried out the aluminium plastic bag material die;
Fig. 4 is the schematic diagram that utilizes after the inventive method is carried out the aluminium plastic bag material die.
The specific embodiment
Referring to Fig. 3,4, a kind of aluminium plastic bag method for die cutting that can suppress to curl of the present invention, end face to plastic-aluminum encapsulation bag 1 before die-cut heats, heating region is near the zone the otch 2, it among the figure hatching position, the control heating-up temperature makes the temperature of end face reach 45 ℃, should guarantee to have between end face and the bottom surface temperature difference about 20 ℃ this moment.
After end face is heated to predetermined temperature range, need in time carry out die-cut, can not be in the high temperature attitude for a long time, in order to avoid material character changes, plastic-aluminum encapsulation bag 1 is positioned on the workbench 3 (bed die) when die-cut, mold from top to bottom, promptly from end face one side of plastic-aluminum encapsulation bag 1 towards the bottom surface one side carry out die-cut.
Fig. 4 as seen, die-cut back is because end face is positioned near the otch 2 zone through preheating, even therefore after the cooling, still can keep the smooth of plastic-aluminum encapsulation bag 1.
Claims (2)
1. aluminium plastic bag method for die cutting that can suppress to curl, it is characterized in that, end face to plastic-aluminum encapsulation bag before die-cut heats, material surface and inner aluminium lamination are heated, end face and and its opposing top layer, bottom surface between 15 ℃～30 ℃ the temperature difference is arranged, from end face one side of plastic-aluminum encapsulation bag towards the bottom surface one side carry out die-cut.
2. the aluminium plastic bag method for die cutting that can suppress to curl as claimed in claim 1 is characterized in that, when plastic-aluminum is encapsulated the end face heating of bag, makes the temperature of end face reach 40 ℃～45 ℃.
